Straw supporting cutting field returning and residual film collecting machine

Abstract

The invention relates to a farmland surface residual film recycling machine, in particular to a straw supporting cutting field returning and residual film collecting machine, and belongs to the field of agricultural machines. By means of the straw supporting cutting field returning and residual film collecting machine, straw can be returned to fields, and residual films can be recycled. The straw supporting cutting field returning and residual film collecting machine comprises a main machine frame, transmission devices and depth wheels. A suspension machine frame is arranged on the front portion of the main machine frame. Root cutting shovels are arranged below the depth wheels. A straw pulling roller and straw pushing wheels are arranged on the main machine frame and rotate oppositely. A driving straw conveying roller and a driven straw conveying roller are arranged behind the straw pushing wheels and rotate oppositely. A straw chopper roller is arranged behind the driving straw conveying roller and the driven straw conveying roller. A baffle is arranged below the straw chopper roller. A film collecting harrow is arranged below the baffle. The straw supporting cutting field returning and residual film collecting machine is reasonable in structure and can meet the requirements for being good in performance, high in mulching film recycling rate, simple in structure, low in consumed power and convenient to popularize, and the working efficiency can be greatly improved.

Description

technical field [0001] The invention relates to a machine for recovering residual film on the surface of farmland, in particular to a machine for collecting residual film by straw support cutting and returning to the field, which can return stems to the field and recover the residual film, and belongs to the field of agricultural machinery. Background technique [0002] Film mulching cultivation technology has the functions of increasing temperature, retaining moisture, resisting drought and promoting root system development, which can greatly increase crop yield and shorten the growth period. However, with the expansion of the mulching area and the increase of the mulching years, the residual film remaining in the field has caused serious pollution to the farmland and the environment. Although there are degradable mulch films available, the popularization and use of degradable mulch films is limited. The cleaning of residual mulch films in farmland still requires a lot of m...

AI Technical Summary

Problems solved by technology

[0004] 1. For harvesting film before irrigation of crops, this kind of machinery can no longer be used because the crops have adopted the water supply method of drip irrigation under the film;

[0005] 2. To recycle the mulch film after the crops are harvested, since the crop stalks must be removed first, the structure is mostly complicated, the price is too high, and it is not easy to promote;

[0006] 3. Spike rollers are also used to prick the film for recycling, but the recovery rate is too low, and the plastic film stuck on the spikes cannot be removed, so it can only be burned with fire after pricking too much, which is troublesome;

[0007] 4. It is cheap and convenient to use film rakes to form film rakes. However, due to the obstruction of straw, the recovery rate is too low, which brings more troubles to farmers, so the promotion has become a problem.
