Description

Technical Field

[0001] The utility model relates to the technical field of residual film recovery equipment, in particular to a residual film picking machine. Background Art

[0002] Nowadays, more and more crops are planted with film mulching. Film mulching is an effective agricultural technology that can increase soil temperature, retain water and fertilizer, prevent diseases and weeds, improve the growth environment, and enhance the soil's ability to retain water and fertilizer, thereby increasing the yield and quality of crops. However, after the crops are harvested, the film needs to be removed when the fields are plowed. Since the ends of the film are buried underground and the film is attached to the ground surface, it is not easy to remove. Manual cleaning is time-consuming and laborious. Therefore, special agricultural machinery is needed to remove the film.

[0003] Through searching, the announcement number is: CN217694224U. A residual film picking machine includes a frame, and the inner walls on both sides of one end of the frame are bolted with protective plates, a cross frame is fixedly connected between the two protective plates, a front shovel is fixedly installed between the two protective plates, and front wheel frames are provided at both ends of the cross frame.

One end of the power transmission component is connected to a conveyor chain through a belt drive, and the conveyor chain is rotatably connected between the two protective plates. The middle part of the frame is connected to a screening drum through roller sliding, and a gearbox is provided between the screening drum and the conveyor chain. This residual film picking machine can turn out the residual film in the soil with a shovel, and the nail teeth provided can prevent the residual film from falling to the ground before reaching the conveyor chain when transferring the residual film, thereby improving its picking efficiency.

[0004] However, there are two problems with this type of residual film picking machine.

Therefore, a residual film picking machine is provided, which is improved on the residual film picking machine mentioned in the background technology, and solves the problem that the existing residual film picking machine cannot crush the collected hard soil blocks wrapped in the ground film and the collected residual film cannot be dumped on the transport vehicle.

[0035] Embodiment 1: Connect the machine to the rear end of the traction device, connect the input shaft of the power transmission device 4 with the power output shaft of the traction device, drag the machine to the edge of the farmland that needs to be cultivated, and then adjust the height of the front walking wheel 101 and the rear walking wheel 15 to make the whole machine descend, so that the front shovel 2 contacts the ground, then start the traction device to move forward, and at the same time turn on the power output shaft of the traction device to drive the power input shaft of the power transmission device 4 to rotate, the soil film scooped up by the front shovel 2 will be transported from front to back by the conveyor belt 5, and when the soil film is transported to the bottom of the soil pressing roller 1206, the rotating soil pressing roller 1206 crushes the soil blocks wrapped by the ground film under the downward pressure of the adjusting rods A1207 and B1208 at its two ends, and the soil blocks are pressed by the soil pressing roller 12 06 After being rotated and crushed, the soil film will leak out from the gap of the conveyor belt 5 when it moves backward on the conveyor belt 5. Then the compacted soil film will be transported to the rear by the conveyor belt 5 and enter the rotating screen film cylinder 1301. Because the compacted soil film is still wrapped with soil and soil particles, the soil and soil particles in the ground film will leak out from the gap of the screen film cylinder 1301 under the rotation of the rotating screen film cylinder 1301. Because the screen film cylinder 1301 is high in front and low in the back, the residual film will be slowly sent into the film collecting bucket 1402 at the rear during rotation. After the film collecting bucket 1402 is full of residual film, the oil cylinder 1404 will be started to lift the film collecting bucket 1402 upward and backward, and finally the residual film in the film collecting bucket 1402 will be poured into the bucket of the transport vehicle behind the film collecting frame 1401.

[0036] Working principle: the power input shaft of the traction equipment drives the power input shaft of the power transmitter 4 to rotate, and then the power output shaft of the power transmitter 4 rotates. The rotation of the power output shaft of the power transmitter 4 drives the second transmission shaft 7 to rotate through the first chain 8. The rotation of the second transmission shaft 7 drives the conveyor belt 5 sleeved thereon to drive the first rotating shaft 6 to rotate. While the second rotating shaft 7 rotates, one end of the second rotating shaft 7 drives the second chain 9 to rotate. The rotation of the second chain 9 drives the input shaft of the gearbox 10 to rotate, and then the gear plate of the output shaft of the gearbox 10 drives the gear plate 1304 connected to the front end of the screen membrane cylinder 1301 to rotate, and then drives the screen membrane cylinder 1301 to rotate under the limiting action of the roller 1302 and roller 1 1303 connected to the inner wall of the side frame 1. At the same time, the rotation of the second rotating shaft 7 will also drive the sprocket 11 connected to its end to rotate, and the rotation of the sprocket 11 drives the first sprocket 1204 to rotate through the third chain 1205, and the first sprocket 1204 drives the second gear 1203 connected thereto. The second gear 1203 rotates, and then the first gear 1202 meshing with it rotates. The rotation of the first gear 1202 drives the soil-pressing roller 1206 connected thereto to rotate. When working, the soil-pressing roller 1206 moves upward due to the soil block cushion wrapped with the ground film. The upward movement of the soil-pressing roller 1206 causes its two ends to slide upward in the arc-shaped through holes 102 opened on the surface of the side frame 1. At this time, the telescopic adjustment rods A1207 and B1208 hinged at both ends of the soil-pressing roller 1206 Rod A12071 and telescopic rod B12081 will be compressed into guide cylinder A12072 and guide cylinder B12082. Under the action of the springs in guide cylinder A12072 and guide cylinder B12082, telescopic rod A12071 and telescopic rod B12081 will be extended, so that the soil pressing roller 1206 will move downward again to crush the soil blocks wrapped in the ground film, so that the soil pressing roller 1206 can crush the soil blocks wrapped in the ground film while rotating, and at the same time has up and down adjustability.

[0037] The film collecting bucket 1402 of the subsequent film collecting assembly 14 will collect the residual film from the film screening cylinder 1301. When it is full, the oil cylinder 1404 will be started, and the telescopic rod of the oil cylinder 1404 will extend to drive the fixed ear 1403 hinged to the telescopic rod to move upward, thereby driving the film collecting bucket 1402 to rotate with the lower end of the connecting arm 1406. As a result, the film collecting bucket 1402 moves backwards with the connecting arm 1406 while the fixed rod 1405 connected to it rotates at the upper end of the connecting arm 1406, until the rear side of the film collecting bucket 1402 leans against the rear end of the film collecting frame 1401, and the film collecting bucket 1401 leans against the mouth and tilts downward to pour out the residual film inside.

[0038] The above description is only a preferred embodiment of the utility model and does not limit the utility model in any form. Any ordinary technician in the industry can smoothly implement the utility model as shown in the drawings of the specification and described above. However, any equivalent changes, modifications and evolutions made by technicians familiar with the profession without departing from the scope of the technical solution of the utility model using the technical content disclosed above are all equivalent embodiments of the utility model.
