The lower part of the beam of the frame, the rear side of the gearbox, the transverse film cutting device is set on the rear side of the disc cutter, the film picking device is set on the rear side of the transverse film cutting device, the film stripping device is set above the film picking device, and the film collecting device is set On the rear side of the stripping device, the film collecting box is set on the back side of the film collecting device, the ground wheels are set on both sides of the frame, and the transmission system of the transverse film cutting device, the film collecting device, and the stripping device are respectively installed on the frame. Above all, the present invention has the characteristics of low impurity rate of collected film, reliable operation, high clean rate and good ground profiling, etc., and can meet the requirements of residual film recovery operation.

Description

technical field [0001] The invention relates to an agricultural land surface residual film recovery operation machine, in particular to a farmland plastic film recovery machine, which belongs to the field of agricultural machinery equipment. Background technique [0002] Film mulching planting technology is an advanced agricultural planting technology that improves and optimizes the growing environment of crops, overcomes the influence of adverse conditions, and achieves early maturity, high yield, high quality and high efficiency. Plastic film mulching planting technology not only increases the effective accumulated temperature and prolongs the growth period of crops, but also can inhibit the growth of weeds; at the same time, it can effectively use land resources and water resources to increase temperature and preserve moisture. Therefore, plastic film mulching technology has important strategic significance to the development of my country's agriculture, especially dry la...

Problems solved by technology

However, due to years of filming and the failure of timely and effective recycling of used plastic films, serious "white pollution" has been caused to the land, resulting in a decline in crop yields year after year. Therefore, the recycling of residual film has become an important issue that needs to be solved urgently in agriculture.

At present, there are two methods of recycling farmland residual mulch film: manual picking and mechanical recycling: manual picking is labor-intensive, low-efficiency, and high-cost; however, although mechanical recycling overcomes the shortcomings of manual picking, because the existing agricultural Thin, with a thickness of only about 0.006mm~0.008mm, low tensile strength, and easy to break. The main types of working parts of existing mulch recycling machines include telescopic rod-toothed pick-up rollers, spring-toothed pick-up parts, and shovel-type stubble pickers. Film collecting parts, gear tooth film collecting parts, tooth chain film collecting parts, etc. These film collecting parts can only recover large pieces of plastic film, but cannot effectively recover plastic film fragments

However, when the above types of residual film recycling parts recycle a large area of ​​plastic film, the residual film contains a relatively large amount of straw, plant branches and leaves, weeds and soil, and the residual film is easy to wrap around the working parts of the film, which affects the continuous recycling operation of the residual film recycling machine. , and the recovery rate of residual film is low. Due to the unevenness of the ground, there is still a large amount of residual film left on the ground after one operation, which is difficult to meet the requirements of residual film recovery.
