Wheel rake type mulching film strip collecting device and mulching film strip collecting type straw returning machine

Abstract

The invention relates to the technical field of agricultural machinery, in particular to a wheel rake type mulching film strip collecting device and a mulching film strip collecting type straw returning machine. The wheel rake type mulching film strip collecting device comprises a strip collecting frame and at least one pair of rake wheel components, wherein strip collecting frame comprises a leftframe pole and a right frame pole, the rake wheel component comprises a rake wheel and a spring cantilever device. The mulching film strip collecting type straw returning machine comprises a returning machine frame, a straw crushing device, an auger device and a wheel rake type mulching film strip collecting device. The wheel rake type mulching film strip collecting device and the mulching film strip collecting type straw returning machine are reasonable and compact in structure and convenient to use. Arranged at the rear part of the straw crushing device capable of conveying crushed straws to two sides of a mulching film, the wheel rake type mulching film strip collecting device and the mulching film strip collecting type straw returning machine can pick up the mulching film by the rakewheels at the left side and the right side and furl the mulching film towards the middle part of a strip collecting interval, so that the mulching film is stacked into a strip shape. Through practicaltests, the collected mulching film contains less broken straws and other impurities, the mulching film is not lifted up in the collecting process and will not be scattered everywhere, meanwhile, themulching film is not easy to be broken, so subsequent packaging and collection and subsequent secondary utilization of the mulching film are easy.

Description

technical field [0001] The application relates to the technical field of agricultural machinery, and relates to a wheel rake type mulch film collection device and a mulch film collection type straw returning machine. Background technique [0002] With the widespread application of film-laying planting methods in arid areas, the agricultural film buried in the soil after the autumn harvest of the year needs to be recycled effectively and in time, otherwise it will cause soil compaction and degradation, resulting in a rapid decline in land quality, which will not only hinder the growth of new crops in the second year. The germination of planted crops also causes environmental pollution. At present, there are many mulch film recycling devices, but the mulch film recovered by the existing mulch film recycling devices is usually relatively broken, which is not conducive to subsequent packaging collection and processing. and other reasons cause the broken residual film to fly arou...

AI Technical Summary

Problems solved by technology

[0003] The purpose of this application is to provide a wheel-rake type mulch collection device and a mulch collection type straw returning machine, which overcome the above-mentioned deficiencies in the prior art, and can effectively solve the problem that the mulch recovered by the existing mulch recovery device is relatively broken, It is not conducive to subsequent packaging collection and processing, and the broken and residual film is easy to fly, causing secondary pollution

[0004] This application further solves the problem that the existing mulch recycling device cannot complete straw crushing and returning to the field at the same time, and multiple operations are required for straw returning to the field and mulching film recycling, resulting in many operation steps, long time consumption, high operating costs, and high debris content after mulching film recycling. Many problems affecting secondary use
