Problems solved by technology

However, there is an obvious deficiency in the pick-up device in this type of residual film recycling machine: in the process of operation, there will always be residual film and plant stems that are difficult to be brushed off by the film brushing mechanism in time and are constantly wrapped around the thorns of the drum. On the nail teeth, the accumulation on the thorn-shaped nail teeth of the drum needs to stop the operation for cleaning before it can work normally
[0012] With the renewal of the concept of agricultural planting, while promoting the cultivation of plastic film, it is also advocated that the crop straw should be crushed and returned to the field to increase the organic matter in the land, which further creates difficulties for the recycling of plastic film

Embodiment 1

[0057] Embodiment 1: with reference to attached figure 1 , figure 2 , is a schematic structural view of the integrated operating machine for crushing and returning mulch film to the field according to Embodiment 1 of the present invention, including a traction or suspension frame 11, a frame 12 and a transmission mechanism, and the frame 12 is sequentially provided with a stalk crushing mechanism, The film edge lifting mechanism 4 and the horizontal membrane mechanism, the stalk crushing mechanism includes a crushing chamber 21, the crushing chamber 21 is a horizontal cylindrical body, the cylindrical body is provided with a fixed knife 20, and the crushing chamber 21 is provided with a rotary knife 22. The rotary knife 22 is set on a drum body. There are two openings on the wall of the cylindrical body of the crushing chamber 21. One opening is located at the front and lower part of the cylindrical body, which is the entrance of the stem, and the other opening is located at ...

Embodiment 2

[0063] Embodiment 2: refer to image 3 , Figure 4 , which is a structural schematic diagram of Embodiment 2 of the present invention. Compared with Embodiment 1, the difference of this embodiment is that: the arm frame 31 of the horizontal membrane mechanism is a frame body, and the frame body is densely covered with tooth bars 32 Form the rake body, and the rake body is arranged on the frame 12 in a group of two in an inverted "eight" shape inclined or transversely.

Embodiment 3

[0064] Embodiment 3: refer to Figure 5-Figure 7 , is a structural schematic diagram of Embodiment 3 of the present invention. Compared with Embodiment 1, the difference of this embodiment is that: the arm frame 31 of the horizontal membrane mechanism is a chain, and tooth bars 32 are densely distributed on the chain to form The rake body, two groups of rake bodies are inclined or transversely arranged on the frame 12 in an inverted "eight" shape, and are driven by the sprocket 35.

Abstract

The invention discloses a method for straw crushing and field-returning and mulching film recycling operation. Firstly, crop straws are crushed and collected to a conveying channel, that is, the crop straws on the mulching film portions are removed in a crushing mode, crushed, and not returned to field immediately; secondly, edge raising and gathering are performed on the mulching film on which the crop straws are removed, the mulching film is gathered into narrower mulching film strips, wider open space is vacated among the mulching film strips, and then the crop straws which are crushed and collected in the conveying channel are released to the open space among the mulching film strips. Compared with the prior art, the method for the straw crushing and field-returning and mulching film recycling operation has the advantages that not only can edge raising and gathering be performed on the mulching film, but also the crop straws can be crushed and returned to the field, and the operation efficiency is high.

Description

technical field [0001] The invention relates to an agricultural mechanical device, in particular to a method for crushing crop stems and returning them to the field for plastic film recycling after autumn crops are harvested, especially a method for integrating crop stem crushing and returning to the field and recycling plastic film. Background technique [0002] The application of plastic film planting technology has become very common, but the residue of plastic film in the land has also become a serious problem. [0003] At present, the first method of recycling residual film is manual recycling, which mainly picks up large pieces of residual film floating on the land surface, which is inefficient and labor-intensive; the second is mechanical recycling, but the current recycling machinery mainly uses hook rakes or sieves Mode. The pick-up effect of the hook rake is poor, especially for small residual film fragments. The sieve type collection effect is better, but the ef...
