Abstract

The invention relates to a clamp finger chain-type used plastic film collector which comprises a traction device, a rack, a film collection device, a film collection driving system, a film stripping device, a film stripping driving device, land wheels and a used plastic film tank, wherein the traction device is arranged at the front side of the rack; the film collection device is arranged at the middle of the rack; the film stripping device is arranged above the rear side of the film collection device; the used plastic film tank is arranged on the rear side of the film collection device; the film collection driving system and the film stripping driving system are respectively arranged on the rack; the film collection driving system is connected with the film stripping device; the land wheels are arranged at two sides of the rack; the film collection device consists of a film collection rack, a tensioning mechanism, a film clamping mechanism and a support chain roll; the tensioning mechanism consists of a support base, a spring, a bracket and a tensioner sprocket; the film clamping mechanism consists of a lower film collection sprocket, an upper film collection sprocket, a film collection chain and a clamp finger; the support chain roll is arranged at the lower sides of the film collection rack and the film collection chain. The clamp finger chain-type used plastic film collector has the advantages of simple structure, high operation speed and high used plastic film recovery rate, and can meet the used plastic film recovery requirement.

Description

technical field [0001] The invention relates to an agricultural land surface residual film recovery operation machine, in particular to a finger chain type residual film recovery machine, which belongs to the field of agricultural machinery equipment. Background technique [0002] Film mulching planting technology is an advanced agricultural planting technology that improves and optimizes the growing environment of crops, overcomes the influence of adverse conditions, and achieves early maturity, high yield, high quality and high efficiency. Plastic film mulching planting technology not only increases the effective accumulated temperature and prolongs the growth period of crops, but also can inhibit the growth of weeds; at the same time, it can effectively use land resources and water resources to increase temperature and preserve moisture. Therefore, plastic film mulching technology has important strategic significance to the development of my country's agriculture, especia...

AI Technical Summary

Problems solved by technology

The telescopic rod-tooth type picking roller film collecting mechanism works reliably and has a high rate of residual film collection, but the structure of the mechanism is complex and the cost is high; the spring-tooth type film-picking part is driven by the ground wheel to collect the spring teeth. The structure is simple and the residual film The film collection rate is high, but it is difficult to manufacture, and it is difficult to separate the residual film and debris, resulting in a relatively high impurity rate; the shovel-type stubble film collection part has a simple structure, reliable operation, and a high recovery rate, but it has requirements for soil performance. It is difficult to separate the residual film from the crop stubble, which is not conducive to the recycling of the residual film; the gear-type film collecting part rotates the film by the friction between the film wheel and the ground, the structure is simple, and the collected residual film has a low impurity rate, which is convenient Recycling and utilization, but the recovery effect of the severely damaged residual film after the harvest of the autumn crops is not ideal, which affects the operation efficiency

[0003] The residual film recovered by the above types of residual film recovery machines contains a relatively large amount of straw, weeds and soil, and the residual film is easy to entangle the working parts of the film collection, which affects the continuous recovery operation of the residual film recovery machine, and the recovery rate of the residual film is low. There are still a large amount of residual film left on the surface, which is difficult to meet the requirements of residual film recycling
