Pickup device of suspension type residual film recovering and bundling combined operation machine

Abstract

The invention discloses a pickup device of a suspension type residual film recovering and bundling combined operation machine. The pickup device comprises a film taking comb and a rotary pickup device which are arranged on a suspension type machine frame; the front ends of the comb teeth of the film taking comb incline downwards and are used for lifting residual films in soil; the rotary pickup device is positioned above the film taking comb; the rotary pickup device comprises a rotary cylinder in rolling connection with the suspension type machine frame; the rotary cylinder is provided with a transmission structure in transmission connection with a driving device; raking finger constraining strip holes are distributed in the cylinder body of the rotary cylinder uniformly; an eccentric shaft is arranged in the rotary cylinder; eccentric rotors are distributed on the shaft body of the eccentric shaft uniformly; the left end and the right end of the eccentric shaft are fixedly connected with the suspension type machine frame; each raking finger constraining strip hole corresponds to one raking finger; the inner end of each raking finger is hinged with each eccentric rotor; the outer end of the each raking finger stretches out of the outer side of the cylinder body of the rotary cylinder through the raking finger constraining strip hole, and corresponds to the comb tooth gap of the film taking comb. The pickup device and effectively pick up small fragmentary residual films, can consider the residual films in deep soil, and has the characteristics of high pickup efficiency, good pickup effect and the like.

Description

technical field [0001] The invention relates to the technical field of agricultural machinery. Background technique [0002] Film mulching is a kind of agricultural cultivation technology, which has the functions of increasing temperature, water retention, fertilizer retention, improving soil physical and chemical properties, increasing soil fertility, inhibiting weed growth, and reducing diseases. It also has the function of reducing humidity in the case of continuous rainfall. Thereby promoting plant growth and development, early flowering and fruiting, increasing production, reducing labor costs, etc. Therefore, with the enhancement of scientific farming concepts, the application of plastic film mulching in agricultural production is becoming more and more widespread. The mulch is not easy to decompose, and the pollution to the environment cannot be ignored. As the residues in the farmland accumulate year by year, its impact cannot be ignored.

[0002] Film mulching is a kind of agricultural cultivation technology, which has the functions of increasing temperature, water retention, fertilizer retention, improving soil physical and chemical properties, increasing soil fertility, inhibiting weed growth, and reducing diseases. It also has the function of reducing humidity in the case of continuous rainfall. Thereby promoting plant growth and development, early flowering and fruiting, increasing production, reducing labor costs, etc. Therefore, with the enhancement of scientific farming concepts, the application of plastic film mulching in agricultural production is becoming more and more widespread. The mulch is not easy to decompose, and the pollution to the environment cannot be ignored. As the residues in the farmland accumulate year by year, its impact cannot be ignored. The thickness of the mulch used in our country is thin, the tensile strength is low, it is easy to oxidize, and it is easy to be broken. Therefore, there is an urgent need for a residual film recycling machine. The residual film picking efficiency of the residual film picking device plays a decisive role in the residual film picking effect of the residual film recycling machine.
