Remnant film recovery device for efficiently cleaning remnant films

Abstract

The invention provides a remnant film recovery device for efficiently cleaning remnant films. The remnant film recovery device comprises a framework and film picking teeth, wherein a connecting mechanism is welded to the external wall of the front end of the framework; and right ends of two middle gears of four gears are rotatably connected with two auxiliary fixing shaft blocks through cylindersand bearings welded to axis positions of the two corresponding gears, and left ends of the two corresponding gears are rotatably connected with a guard shield and corresponding positions thereof through the cylinders and bearings welded to axis positions of the two corresponding gears. According to the remnant film recovery device, a first remnant film cleaning roller and a second remnant film cleaning roller are sequentially arranged at the inner end of the framework from front to back, and the first remnant film cleaning roller and the second remnant film cleaning roller are of engaged rotation through the four gears. When the remnant film recovery device is in use, firstly, the first remnant film cleaning roller hooks up remnant films buried in soil, thus, soil and stones covering the remnant films fall off, and thus, a plurality of subsequent remnant film intercepting hooks can conveniently intercept the remnant films hooked from the soil and drive recovery.

Description

technical field [0001] The invention belongs to the technical field of agricultural equipment, and in particular relates to a residual film recovery device for efficiently cleaning residual film. Background technique [0002] With the improvement of agricultural production level, the role of agricultural residual film in agricultural production is increasing, which promotes the increase of farmers' production and income. However, with the continuous increase in the amount of use, farmers' awareness is not enough, resulting in unfavorable cleaning and recycling of agricultural residual film, and the amount of soil residue is increasing year by year, which has brought serious negative effects to the agricultural ecological environment. Therefore, it is urgent to remediate the pollution of agricultural residual film. A large amount of residual agricultural film is difficult to be decomposed naturally in the soil, which affects the water, fertilizer, gas and heat activities in t...

AI Technical Summary

Problems solved by technology

[0005] In order to solve the above technical problems, the present invention provides a residual film recovery device for efficiently cleaning residual film, so as to solve the problem that the existing residual film recovery device recovers the residual film due to the relatively weak material of the residual film. Under the cover of heavy soil and stones, only a part of the residual film is hooked by the residual film device, because the hook length of the residual film is too long and the remaining part is hooked under the cover of heavy soil and stones. The part is prone to breakage, resulting in the remaining residual film remaining in the soil, which requires multiple recycling operations, which affects the efficiency of the problem
