Compared with the conventional track driving technology, the crawler belt of the present invention is connected by the track chain through the rotating shaft, and the corner of the casing is caught in the chain slope of the track chain to drive the track to rotate, and the principle is similar to the principle of the conventional track and the driving wheel; The body corner and the adjacent sharp corner are covered by the retaining sleeve, the inner panel and the side baffle to prevent the general weed or the wrap object from being wound around the sharp corner of the driving wheel, thereby causing the crawler wheel to fail; Passability.

The rotation of the drive wheel housing will drive the track movement through the sharp corner. After the corner of the housing contacts the track, the top surface of the chain of the track chain exerts a downward force on the cover, the top shaft and the inner plate, and then the top axial direction Moving, at the same time driving the telescopic body composed of the baffle and the inner plate to rotate around the end shaft, and the top shaft drives the side baffle to swing downward, so that the sharp corner completely leaks out and protrudes into the chain bevel in the track chain; Acts with the chain bevel to drive the chain. In order to block the sharp corners in the design, a structure such as a retaining sleeve is used, in which the inner panel can slide in the retaining sleeve, which belongs to the telescopic structure, and the distance between the top shaft and the end shaft in the lower axial movement. Will increase, this increase in distance is compensated by the extension of the inner panel from the retaining sleeve; the total length of the inner panel in the retaining sleeve is 1/2 of the total length of the retaining inner panel completely extending the retaining sleeve, and completely When the protrusion is extended, the top shaft should be at the bottom end of the groove between the sharp corner and the sharp corner. The retaining sleeve and the inner panel are in contact with the sharp bevel, which requires that the distance between the adjacent sharp corners is larger than the sharp bevel. The length of 1/2; theoretical calculations show that the angle of apex angle of 50-65 degrees can meet the above structural requirements. The sharp corner angle in the present invention is much larger than that of the conventional driving wheel, which causes the casing to fall off when the crawler belt is driven, so that an adjustment mechanism is added to the design. The adjusting mechanism uses the downward movement of the top shaft to obtain power, and relies on the power to push the card out from the card passage at the top end of the pointed corner, and the ejected card board cooperates with the chain top of the track chain to prevent the drive from falling off. In the adjusting mechanism, the S-shaped lever can rotate around the sliding shaft and can move along the axis of the sliding shaft, compressing the first spring during movement, the first spring has a reset function for the S-shaped lever, the rotating scroll spring, the scroll spring The S-type lever also has a reset function; because the rotation of the S-type lever causes the first spring to rotate, and the rotation of the first spring destroys the compression performance of the first spring, a rotating mechanism is designed to eliminate the S-type lever rotational motion. The effect on the first spring; the same S-type lever movement will drive the scroll spring to move, so the designed inner fixed block can move laterally with the scroll spring, but does not affect the compression of the scroll spring. The rotation of the S-shaped lever and the movement of the first spring in the rotational direction are blocked by the sliding of the first annular sleeve and the second inner ring in the rotating mechanism. The S-type lever is designed to have an S-shaped lever because The distance between the pressure plate and the card plate pressed by the top shaft is small, but the amplitude of the up and down movement is large. In this case, it is impossible to install the linear lever transmission motion on the lower side of the both sides, which easily leads to the lever. With the pressure plate and the card plate falling off, the S-shaped lever is designed to prevent falling off and ensure smooth transmission. The top shaft middle rotation sleeve in the middle of the top shaft is connected with the pressure plate, and the movement of the top shaft drives the pressure plate to move; when the top axial direction moves downward, the pressure plate is driven to move downward, and the pressure plate applies the concave surface to the S-shaped lever surface. Under the force, the S-shaped lever rotates around the sliding axis, and the S-shaped lever convex surface will jack up the card board, and the card board passes through the card channel upwards, and at the same time compresses the leaf spring, and the leaf spring is designed to reset the card board. During the S-type lever rotary motion, a certain force is transmitted to the trigger mechanism. At the beginning of the rotation, the pressure plate moves downward, and the side of the S-shaped lever contacts the trigger horizontal plate, and the trigger horizontal plate, the trigger vertical rod and the trigger block can be The slidably slides along the traverse guide groove; the lower side of the pressure plate contacts the trigger slant surface of the trigger block, and the trigger block slides up and down through the vertical movement vertical plate in the vertical movement guide groove. When the pressing plate moves downward, the trigger block generates driving in two directions. On the one hand, the trigger block moves toward the vertical moving rail, and on the other hand, moves downward, and the second spring and the third spring are both compressed and triggered. The lateral movement of the block causes the contact surface of the trigger block and the pressure plate to gradually become the trigger plane, and then moves downward with the trigger block; when the track chain is ready to be separated from the corner of the housing, the trigger vertical rod is moved down to the card slot and The card block cooperates, and the card block is inserted into the card slot through the sliding of the third telescopic rod and the third telescopic sleeve, and the card block arc and the card slot bevel are designed to facilitate the card to enter the card. In the slot; when the track chain starts to leave the corner of the housing, the top shaft moves up, the pressure plate moves, and the S-shaped lever is reset by the scroll spring. At this time, the trigger block cannot be stuck because the card block is stuck. Move up and down, but the trigger block moves in the direction of the S-shaped lever under the action of the third spring, and the S-shaped lever slides along the sliding axial fixed column by triggering the horizontal plate, and the sliding of the S-shaped lever causes the card on the lower side of the card The lever is disengaged from the S-type lever and Into the gap of the S-type lever, the card loses the role of the S-shaped lever top, and moves downwards in time under the action of the leaf spring to prevent the top end of the card from being separated from the chain top and disturbing the track chain from the sharp corner; triggering The lateral movement of the horizontal plate will cause the block to gradually disengage from the card slot. When the card block is separated from the card slot, the card slot, the triggering vertical rod and the trigger block will move upward under the action of the second spring, and return to the lower side of the pressure plate. Trigger the original position of the ramp contact. The first telescopic rod and the first telescopic sleeve, the second telescopic rod and the second telescopic sleeve are designed to increase the lateral stability when the spring is compressed. The design of the top-shaft side swivel sleeves on both sides of the same top shaft, the same end shafts are staggered from each other, and the two anti-collision block lugs are designed to provide two swivel sleeve rotations by using one rotating shaft. The top shaft drives the side baffle to rotate, and the side baffle moves to the lower side of the sharp side, and no interference occurs between the side baffles. The invention uses the driving wheel for shielding the sharp corners, can prevent the general weeds or the entangled objects from being wound around the sharp corners on the driving wheel, causes the failure of the track wheel, improves the passability of the track wheel, and has better practical effect. .

The rotation of the drive wheel housing will drive the track movement through the sharp corner. After the corner of the housing contacts the track, the top surface of the chain of the track chain exerts a downward force on the cover, the top shaft and the inner plate, and then the top axial direction Moving, at the same time driving the telescopic body composed of the baffle and the inner plate to rotate around the end shaft, and the top shaft drives the side baffle to swing downward, so that the sharp corner completely leaks out and protrudes into the chain bevel in the track chain; Acts with the chain bevel to drive the chain.

The sharp corner angle in the present invention is much larger than that of the conventional driving wheel, which causes the casing to fall off when the crawler belt is driven, so that an adjustment mechanism is added to the design. The adjusting mechanism uses the downward movement of the top shaft to obtain power, and relies on the power to push the card out from the card passage at the top end of the pointed corner, and the ejected card board cooperates with the chain top of the track chain to prevent the drive from falling off. In the adjusting mechanism, the S-shaped lever can rotate around the sliding shaft and can move along the axis of the sliding shaft, compressing the first spring during movement, the first spring has a reset function for the S-shaped lever, the rotating scroll spring, the scroll spring The S-type lever also has a reset function; because the rotation of the S-type lever causes the first spring to rotate, and the rotation of the first spring destroys the compression performance of the first spring, a rotating mechanism is designed to eliminate the S-type lever rotational motion. The effect on the first spring; the same S-type lever movement will drive the scroll spring to move, so the designed inner fixed block can move laterally with the scroll spring, but does not affect the compression of the scroll spring. As shown in FIG. 12, the rotation of the first ring sleeve and the second inner ring is used to isolate the rotation of the S-type lever and the movement of the first spring in the rotational direction. The S-type lever is designed to have an S-shaped lever because the distance between the pressure plate and the card plate pressed by the top shaft is small, but the amplitude of the up-and-down motion is large. In this case, a straight line is installed on the lower side of the both sides. It is impossible to transmit the lever, which is easy to cause the lever and the pressure plate and the card to fall off. Therefore, the S-type lever is designed to prevent falling off and ensure smooth transmission. The top shaft middle rotation sleeve in the middle of the top shaft is connected with the pressure plate, and the movement of the top shaft drives the pressure plate to move; as shown in a in FIG. 5 and FIG. 2, when the top axial direction moves downward, the pressure plate is driven downward. Movement, the pressure plate applies a downward force to the concave surface of the S-shaped lever, and the S-shaped lever rotates around the sliding shaft. As shown in FIG. 16, the S-shaped lever convex surface will jack up the card, and the card plate passes through the card passage upwards. At the same time, the leaf spring is compressed, and the leaf spring is designed to reset the card. During the S-type lever rotation movement, a certain force is transmitted to the trigger mechanism, and at the beginning of the rotation, The pressing plate moves downward, the side of the S-shaped lever is in contact with the triggering horizontal plate, and the triggering horizontal plate, the triggering vertical rod and the triggering block can slide laterally along the lateral guiding groove; the lower side of the pressing plate contacts the triggering inclined surface of the trigger block, and the trigger block The vertical movement is performed by sliding the vertical plate in the vertical movement guide groove. When the pressing plate moves downward, the trigger block generates driving in two directions. On the one hand, the trigger block moves toward the vertical moving rail, and on the other hand, moves downward, and the second spring and the third spring are both compressed and triggered. The lateral movement of the block causes the contact surface of the trigger block and the pressure plate to gradually become the trigger plane, and then moves downward with the trigger block; when the track chain is ready to be separated from the corner of the housing, the trigger vertical rod is moved down to the card slot and The card block cooperates, and the card block is inserted into the card slot through the sliding of the third telescopic rod and the third telescopic sleeve, and the card block arc and the card slot bevel are designed to facilitate the card to enter the card. In the notch; as shown by b in Fig. 5, when the track chain starts to break away from the corner of the casing, the top shaft moves up, the pressure plate moves, and the S-shaped lever is reset by the scroll spring. The card block catches the card slot and cannot move up and down, but the trigger block moves in the direction of the S-shaped lever under the action of the third spring, and the S-shaped lever slides along the sliding axis in the direction of the fixed column by triggering the horizontal plate, as shown in FIG. 15 As shown, the sliding of the S-shaped lever makes the card The lower side of the card lever is separated from the S-shaped lever and enters the gap of the S-shaped lever. The card loses the role of the S-shaped lever top, and moves downwards in time to prevent the top end of the card and the chain top. Without disengagement, the track chain is disengaged from the sharp corner; the lateral movement of the triggering horizontal plate causes the block to gradually come off the card slot. When the card block is separated from the card slot, the card slot, the triggering vertical bar and the trigger block will be under the action of the second spring. Move up and return to the original position where the lower side of the pressure plate is in contact with the trigger bevel. The first telescopic rod and the first telescopic sleeve, the second telescopic rod and the second telescopic sleeve are designed to increase the lateral stability when the spring is compressed. The design of the top-shaft side swivel sleeves on both sides of the same top shaft, the same end shafts are staggered from each other, and the two anti-collision block lugs are designed to provide two swivel sleeve rotations by using one rotating shaft. The top shaft drives the side baffle to rotate, and the side baffle moves to the lower side of the sharp side, and no interference occurs between the side baffles. The invention uses the driving wheel for shielding the sharp corners, can prevent the general weeds or the entangled objects from being wound around the sharp corners on the driving wheel, causing the failure of the track wheel, improving the passability of the track wheel, and having better practical effects. .
