[0003]

Such scraper 1
Since No. 2 is worn by the rotation of the compaction roller 5, if a scraper 12 having a large width (D in FIG. 5) is used in order to maintain the scraping function for a long time, the conventional device is not Since the scraper 12 is connected to the swinging member 4 at its upper end portion, the amount of protrusion to the tip end in the direction of the pressure roller is large. Therefore, the attached matter R attached to the rotating outer peripheral surface 5a of the pressure roller is bent relatively easily (that is, the stiffness is weak), and a sufficient resistance force to scrape off the attached matter R is obtained. Therefore, there is a problem that a predetermined scraping function cannot be obtained. The problem of the present application is to provide the outer peripheral surface 5 of the pressure roller with the scraper 12 for a long period of time.
It is to obtain an adhered substance removing device that can reliably remove the adhered substance of a.

[0004]

[Means for Solving the Problems] In order to solve the above problems,
In the present application, a swing support is swingably supported in a vertical direction on a frame that rotatably supports a pressure roller, a scraper is attached to the swing support, and the scraper is pressed against the outer surface of the pressure roller by a spring force. In the adhering material removing device for the pressure roller, the scraper is detachably attached to the swing support at the center portion in the width direction.

[0005]

According to the above, even if the width of the scraper is made large corresponding to the extension of the wear life, the scraper is attached to the swing support body at the central portion thereof. The scraper becomes smaller than in the conventional case in which one end of the scraper is attached to the swing support, and as a result, the rigidity is increased and the bending due to the adhered material is reduced, so that the adhered material can be reliably scraped off. In addition, if one end of the scraper is worn, it can be used from the other end by removing it from the central portion, turning it upside down, and reattaching it, and it is possible to maintain a high scraping function for a long period of time.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. In FIG. 3, in the frame 3, a compaction roller 5 for compaction is rotatably supported between the left and right roller support portions 3 a, and the frontmost end of the compaction roller 5 projects forward from the front end of the frame 3, The pressure roller 5 and the front surface of the frame 3 are made parallel to each other. The compaction roller 5 is configured so that the rotational force transmitted from a drive source (not shown) is switched by a well-known forward / reverse switching device to rotate forward / reversely, so that the compaction vehicle 2 moves forward / backward. Further, by operating the handle 6, the guide roller 5A provided at the rear portion of the frame changes the traveling direction of the compaction vehicle 2.

Next, the attached matter removing device 1 will be described. In FIGS. 1 and 2, a pair of left and right support members 4 are fastened to the lower surface of the front end of the frame 3 at a position that is inward from the end surface of the compaction roller 5 in the vehicle width direction (left and right direction in FIG. 2). A plate-shaped rocking member 10 is supported by a support pin 8 on the outer surface of the support member 4 in the vehicle width direction so as to be vertically rockable. A plate 11, which is shown as a mounting member, is integrally welded between the left and right rocking members 10 and is horizontally mounted to form a rocking support 7. The plate 11 has a mounting surface 11b having a length that is at least half the width (vertical length) D of the scraper 12 described below, and has a lower end portion in the axial direction of the pressure roller 5 (left and right of the frame 3). A plurality of mounting holes 11c are provided at a predetermined pitch Q in the width direction). On the other hand, the scraper (removal member) 12 has a length in the left-right direction that is substantially equal to the axial length of the pressure roller 5 and the roller 5 for a long period of time.
The width D is set to be large in consideration of the wear caused by. The scraper 12 is made of polyurethane, for example, and a mounting hole 12c corresponding to the mounting hole 11c is provided on the center line S in the width direction of the scraper 12. The scraper 12 includes a mounting plate 11 and a contact plate 13 having a mounting hole 13c corresponding to the mounting hole 12c.
The center line S is formed by the bolts 14 inserted into 12c and 13c.
It is held and fastened at the part (center part in the width direction). Further, the swinging member 10 is pulled upward by the pulling force of the spring 17 stretched between the pin 15 of the supporting member 4 and the pin 16 of the swinging member 10, and in the state of FIG. It is in contact with the attached eccentric cam 9. By eccentrically rotating the eccentric cam 9 to adjust the position, the eccentric cam 9 and the swinging member 1 can be adjusted.
The pressure contact position of 0 is changed, the vertical position of the scraper 12 is adjusted, and the pressure contact state of the tip of the scraper 12 with the outer peripheral surface 5a of the pressure roller 5 is adjusted. This position of the scraper 12 is the pressure contact position A for removing the deposits on the pressure roller 5.

Next, the upper end of the plate 11 of the swing support 7 is bent into an L-shape, and the abutment surface 11a on the upper surface, as shown at position B in FIG. The spring 17 acts to abut the slope 4a of the support member 4 when the temperature exceeds the limit, and the position B of the scraper 12 removes the deposit R from the pressure roller 5.
Is an open position B far away from the pressure roller 5 for cleaning when scraped by the scraper 12.

Next, the intermediate locking mechanism 25 will be described.
On the side surface of each support member 4, a locking member 20 is swingably moved forward and backward through a pin 18 on the outside of the swinging member 10 in the left-right vehicle width direction. A locking pin 19 is provided at the lower part of each locking member 20 so as to project toward the swinging member 10, and the locking groove 10a provided in the swinging member 10 and the locking pin 19 of the locking member 20 can be engaged with each other. I am doing it. Then, the locking groove 10a
When the locking pin 19 is engaged with the locking pin 19, the scraper 12 is separated from the outer peripheral surface 5a of the pressure roller 5 as shown in the position C of FIG. It is adapted to be held at an intermediate position C on the inner side by the pulling force of the spring 17.

[0010] The adhering matter removing apparatus 1 configured as described above.
The scraper 12 has its tip pressed against the outer peripheral surface 5a of the pressure roller 5 at the pressure contact position A, and removes the adhering matter R adhering to the outer peripheral surface 5a of the roller 5 by scraping it off as the roller 5 rotates. At this time, the amount of protrusion of the scraper 12 from the bolt 14 is half the width D of the scraper 12, and compared to the conventional structure in which the scraper 12 having the same width is attached to the swing member at one end, strong. Therefore, the attached matter R is less likely to bend, and the attached matter R can be reliably scraped off. Adhesion R on the outer peripheral surface 5a of the pressure roller 5
When the scraper 12 is worn by scraping off the scraper, the bolt 14 is removed, the scraper 12 is turned upside down, and the scraper 12 is attached to the plate 11 again by the bolt 14. By doing so, the other end side of the scraper 12 can be made to function as a completely new scraping action portion, and the scraper 12 can be made to continue the scraping operation in a strong state. In addition, the scraper 12 is used in a state where there is no wear (FIG. 1), and the scraper 12 is used.
If the lower part of the back surface of the is worn down in the thickness direction (Fig. 4),
Replace the top and bottom (Fig. 4), then reverse the back side and the front side, and once again the bottom side of the back side is half worn in the thickness direction (Fig. 4).
), And the top and bottom may be exchanged (FIG. 4).

During the rolling operation in which no foreign matter adheres to the outer periphery of the pressure roller 5, the scraper 12 is separated from the outer periphery of the roller 5 and the engaging groove 10a and the pin 19 of the engaging member 20 are engaged, so that the scraper 12 is engaged. Is held at an intermediate position C inside the vertical plane L including the outer end P of the pressure roller 5. Even if the compaction vehicle 2 moves, the scraper 12 is inside the vertical plane L including the outermost end P of the outer periphery of the compaction roller 5,
Even when rolling is performed near the wall surface of a building, it does not come into contact with the wall and will not be damaged. When the scraper 12 is rubbed against the scraper and needs to be cleaned, the scraper 12 is rotated further upward to bring the contact surface 11a into contact with the slope 4a, and the scraper 12 is moved to the open position B where the clean of the sticker is easy. Cleaning is performed by holding and scraping off the adhered matter scraped on the scraper 12.

From the pressure contact position A to the intermediate position C, the scraper 1
When moving 2, the operator rotates the scraper 12 clockwise so as not to cross the dead center and releases the hand, and the locking member 20 swings from the state of FIG. 2 to the vertical position by its own weight. Since the locking pin 19 of the locking member 20 naturally enters the locking groove 10a, the operation of positioning it at the intermediate position C is easy.
In this embodiment, the scraper is provided for the front roller of the compaction vehicle, but the scraper may be provided for the rear roller. If a push-pull wire is connected to the swing member so that the position of the swing member can be switched from the driver's seat, the operator does not have to step down from the driver's seat and operability is improved.

[0013]

As described above, according to the invention of the present application, when the width of the scraper is set to be large so as to correspond to the extended wear life, the scraper is attached to the swinging member at the center portion in the width direction. , The amount of protrusion from this mounting portion is smaller than in the conventional case where a scraper of the same width is mounted on the swing member at one end, and as a result, the scraper is less likely to bend and Becomes stronger, and the deposit can be scraped off reliably. Moreover, if one end of the scraper becomes worn, it can be removed from the center and turned upside down to be reattached. In this way, the other end of the scraper with a large width can be used, and a high scraping function can be achieved for a long time. Can be maintained.
