Detailed ways

The tobacco harvester shown in Figures 1 to 3 includes a vehicle frame and a vehicle part. The vehicle frame includes a main frame top plate 8, a left bottom leaf box baffle 13 and a right bottom leaf box baffle 2. The main frame The top plate 8 is connected with the left bottom leaf box baffle plate 13 and the right bottom leaf box baffle plate 2 through several vehicle frame frames. Engine 7 and tobacco leaf collection box 26 are housed on the main frame top plate 8, left main conveyer belt 25 is housed between left side bottom leaf box baffle plate 13 and tobacco leaf collection box 26, right bottom leaf box baffle plate 2 and tobacco leaf collection The right side main conveyor belt 22 is housed between the case 26, the left side main conveyor belt 25, the right side main conveyor belt 22, the middle part main conveyor belt 23 link to each other with the engine 7 by the conveyor belt input system 21. The vehicle frame is divided into three groups of the left side, the middle part and the right side, and each group is distinguished from the front and back, the inner and outer sides or the left and right sides. 15. Between the middle front left frame frame 9 and the middle front right frame frame 6, a middle bottom conveyor belt 17 is installed, and between the right front inner frame frame 5 and the right front outer frame frame 3, a right bottom conveyor belt 19 is installed . The left bottom conveyor belt 15 , the middle bottom conveyor belt 17 and the right bottom conveyor belt 19 are also connected to the engine 7 by a conveyor belt input system 21 . the

As shown in Fig. 6 and Fig. 7, the structure of each tobacco harvesting knife box in the present invention is illustrated by taking the left outer tobacco harvesting knife box 11 as an example. Tobacco leaf harvesting knife box 11 has box top vertical bar 34, left cross bar 35 and right cross bar 35 ', and tobacco leaf gathers motor 30 in the knife box, and motor main shaft links to each other with supporting shaft 39 by shaft coupling 36, and tobacco leaf harvesting The rotating disk slider mechanism is also housed in the knife receiving box, and the rotating disk 31 of the rotating disk sliding block mechanism is contained on the supporting shaft 39, and the rotating disk 31 is fixed with the rotating disk outer end pin 37, and the rotating slider 32 and the rotating disk outer end pin 37 constitutes the connection relationship of the rotating pair (the connection of the rotating pair refers to that when the pin shaft 37 at the outer end of the turntable rotates, it drives the rotating slider to rotate synchronously), and the rotating slider 32 and the guide rod 33 constitute the connecting relationship of the moving pair (the connecting relationship of the moving pair Refer to the rotating slide block 32 and the guide rod 33 to refer to the connection that the two can relatively move in the horizontal direction), the guide rod 33 is located in the chute 40 on the tobacco leaf harvesting knife box, and the lower end of the guide rod 33 passes through the clamping disc 38 It is connected with the flexible cutter head 16, and the flexible cutter head 16 is disc-shaped. The flexible cutter head is a flexible cutter head made of rubber material, plastic material or other materials. the

The tobacco leaf harvesting knife box is divided into the left outer tobacco leaf harvesting knife box 11, the left inner tobacco leaf harvesting knife box 11', the right outer tobacco leaf harvesting knife box 4 and the right inner tobacco leaf harvesting knife box 4', as shown in Figures 4-5 Shown, the main frame roof 8 is equipped with a hanger 28 on the collection box, and the box top vertical bar of the left outer tobacco leaf collection knife box 11 is fixed on the top hanger 28 of the collection box by a bolt 28 ', and the left cross bar 35 Fixed in the fixing groove on the left rear outer frame frame 24 by bolts, the right cross bar 35' is fixed in the fixing groove 10' on the left front outer frame frame 10. The left inner tobacco leaf harvesting knife box 11' is installed between the middle front left side frame frame 9 and the middle rear left side frame frame in the same connection mode, and the right outer side tobacco leaf harvesting knife box 4 is installed on the right front inner side frame frame 5 and between the right rear inner side frame frame, the right inner side tobacco leaf harvesting cutter box 4 ' is contained between the middle front right side frame frame 6 and the middle rear right side side frame frame. the

The driving part includes a front wheel steering system 20 and four wheels, wherein the front wheel steering system 20 controls the forward direction of the right front wheel 1 and the left front wheel 14, and the right rear wheel 14' and the left rear wheel are driven by the engine. the

The stress principle of the present invention is as follows: when the motor 30 drives the rotating disk 31 to rotate, the guide rod 33 rotates thereupon, the force on the guide rod 33 can be decomposed into two directions, horizontal and vertical, and the force in the horizontal direction makes the rotating slider 32 and The guide rod 33 slides relatively in the horizontal direction, and the force in the vertical direction makes the guide rod 33 move up and down along the chute 40 in the vertical direction. the

Take the left outer tobacco leaf harvesting cutter box 11 as an example to illustrate the working method of the present invention: after the motor 30 starts, it is passed to the rotating disk 31 of the rotating disk slider mechanism through the coupling 36, and the rotating disk 31 rotates 360 ° to be a movement cycle. In the movement cycle, corresponding to each position of the turntable 31, the guide rod 33 occupies each specific horizontal position. At the same time, the vertical part of the guide rod 33 bottom reciprocates up and down in the chute 40, and the flexible cutter head 16 at the lower end moves up and down with the guide rod 33, and the tobacco leaves at the stem part are slapped under the downward action of the beating force. down, fall into the bottom harvesting box, and send it into the right main conveyor belt 22, the middle part main conveyor belt 23, the left main conveyor belt 25 by the left bottom conveyor belt 15, the middle bottom conveyor belt 17, and the right bottom conveyor belt 19, and finally send Into the tobacco leaf collection box 26. Because the contact area of the flexible cutter head 16 (disc-shaped cutter head) and the tobacco leaf is larger, so the stress on the unit area of the tobacco leaf is less, so the flexible cutter head 16 can both pat the mature leaf stem from the root when beating. broken without damaging the tobacco leaves. the

The average height of tobacco is about 1.5m, and the height of the main frame top plate 8 of the tobacco harvester exceeds the average height of tobacco. As shown in Figure 3, when the harvester is walking forward, the right front inner side frame frame 5 and the middle front right side frame frame 6 points across the left and right sides of the right ridge tobacco rod 29', while the left front inner side frame frame 10, 9 points in the front left side of the vehicle frame frame straddle the left and right sides of the left ridge tobacco rod 29. The flexible cutter head protruding from the harvesting knife box reciprocates up and down to slap the tobacco leaves on the tobacco rods 29, 29', causing the tobacco leaves to break from the stalks, and under the action of the downward slapping force, fall into the tobacco leaves on the stems respectively. In the bottom leaf case of left, middle and right position, tobacco leaf is sent on the main conveyer belt respectively by the bottom conveyer belt of bottom leaf case bottom then, and finally sends in the tobacco leaf collecting box 26 of top. the

Since the tobacco matures from the bottom to the top, the first layer of tobacco leaves at the bottom is harvested for the first time, and after a period of time, the second and third layers are harvested at different times according to the maturity, and the upper layer is gradually harvested. receive. By putting the left and right crossbars of the harvesting box into different fixing grooves on the vehicle frame, the position of the harvesting box can be changed from bottom to top. the

The engine 7 is a diesel engine with a generator. the
