A farmland harvester

Abstract

The invention discloses a farmland film harvesting machine, which comprises a frame on which a film lifting structure, a film rolling mechanism and a film winding mechanism are arranged, wherein the film winding mechanism includes a film unloading assembly and a conveying device, and the film unloading assembly is arranged on On the transfer box of the frame, the film unloading assembly acts on the film rolling wheel of the film rolling mechanism; the conveying device is arranged at the discharge end of the film unloading assembly, and the conveying device includes a first pulley device and a second pulley device. The pulley device is arranged on the truss on the frame, the second pulley device is arranged on the transfer box, and the first pulley device and the second pulley device send the recycled plastic film into the film collection box. Due to the adoption of the above structure, the present invention can not only recycle the mulch film, but also prevent the mulch film fragments from being left in the field and causing white pollution.

Description

technical field [0001] The invention relates to the field of agricultural equipment, in particular to a farmland film harvester. Background technique [0002] Mulch film is the ground covering film, usually transparent or black PE film, and there are also green and silver films, which are used for ground covering to increase soil temperature, maintain soil moisture, maintain soil structure, prevent pests from invading crops and diseases caused by certain microorganisms, etc. , the function of promoting plant growth. When a crop matures, the plastic film needs to be recycled in time to plant other crops. At the same time, it can also prevent the plastic film from staying in the field and causing damage to the soil and ecological environment. In the prior art, the plastic film The removal of most of them adopts manual cleaning and collection mode, which is labor-intensive and high-efficiency. [0003] Chinese patent CN201720442703.9 discloses a farmland film harvesting machin...

AI Technical Summary

Problems solved by technology

[0004] The mulch film in the above patent document will be rolled on the roll film wheel after being picked up by the film lifting teeth, and it needs to be manually unloaded before it can be recycled. The labor intensity is high and the work efficiency is low. In addition, the starting film in the above patent document The filming teeth are all set on the same level. Since the plastic film is in a state of low middle and high sides when covering the crops, the filming teeth set on the same level are likely to form more residual film during the filming process, and It is not easy to pick up the whole piece of mulch by the roots. In this way, the formed residual film left in the farmland will damage the soil and ecological environment and form white pollution
