Description

A machine tool for removing and recycling farmland residual mulch film

The utility model belongs to the field operation machinery in the agricultural machinery, in particular to a machine tool for removing and recovering the agricultural mulch film remaining on the ground surface and in the cultivated layer.

In the prior art, film clearing and land preparation operations are carried out separately, and two kinds of machines are used to work independently. Membrane clearing mechanisms are often unreliable. Or it requires a lot of auxiliary labor and consumes a lot of power. Use the following method:

1) Manual removal and recycling, the work efficiency is low, sometimes it is too late to recycle, and the deep residual film is not easy to clean.

2) Elastic-tooth film rake machine, which uses the principle of a hay rake or a rolling tooth disc to integrate the residual film on the surface into piles or strips, and then manually pick up the residual film in the pile. This method has a low removal rate, especially cannot remove the edge film and deep film, and the overall productivity is low.

3) 1MC-70 type waste film recovery machine, the working principle is to cut off, loosen and lift all the surface soil with a flat bucket, and then remove the soil, residual film, root stubble, large soil clods and other miscellaneous materials through the conveyor belt. The material is conveyed into the screen drum, the broken soil and fine sundries are screened out, and then the cleared mixture is poured into many piles or strips, and the residual film and root stubble in the pile are picked up by hand. This method has a high removal rate, but consumes a lot of power, has a complex structure, low production efficiency, shallow working depth, and requires a lot of auxiliary labor.

The residual film left near the upper surface of the stripping cylinder 3, together with the stubble, weeds and other sundries, is pushed backwards and upwards through the high-speed reverse-rotating impeller 4 on the stripping cylinder 3 to make it away from the stripping The drum 3 enters the shroud 5 and is conveyed upwards and backwards. When the residual film and sundries reach the inclined conveyor belt 6, they are sent to the vibrating film collecting frame 7 by the conveyor belt 6. The effect of the tooth 8 is to further crush the soil and level and compact the ground surface. When the film cleaning machine is working in the plowed field, a set of driven deep-lift film teeth can also be used, that is, the deep residual film is collected and lifted to the surface layer reached by the reverse-rotary gear rod, and then the gear rod 22 to further promote and collect film.
