Self-unloading type residual film recycling machine for straw smashing and returning to field and lifting chain bundling and using method

Abstract

The invention relates to a self-unloading type residual film recycling machine for straw smashing and returning to field and lifting chain bundling and a using method. The residual film recycling machine comprises a rack, a straw smashing and returning-to-field device and a residual film picking and conveying device, wherein the straw smashing and returning-to-field device and the residual film picking and conveying device are arranged on the rack, a residual film bundling self-unloading device is arranged behind the residual film picking and conveying device, the straw smashing and returning-to-field device comprises a smashing shell, the front end of the smashing shell is connected with the machine tool through a three-point suspension mechanism, a stubble cleaning mechanism is arranged on the lower portion in the smashing shell, and a horizontal conveying mechanism is arranged above the stubble cleaning mechanism; the residual film picking and conveying device comprises a film lifting shovel and an inclined conveying mechanism, and the film lifting shovel is used for separating mulching films from the ground, so that the mulching films are conveyed upwards under the action of the inclined conveying mechanism; and the residual film bundling self-unloading device comprises a film collecting box with a top opening, a film collecting box connecting rod and a hydraulic cylinder, the film collecting box is arranged behind the residual film picking and conveying device through the film collecting box connecting rod, the hydraulic cylinder is arranged outside the film collecting box, one end of the hydraulic cylinder is connected with the film collecting box, and the other end of the hydraulic cylinder is connected with the inclined conveying mechanism.

Description

technical field [0001] The invention relates to the technical field of agricultural residual film recycling, in particular to a straw crushing and returning to the field, lifting chain, rolling, bundling and self-unloading residual film recycling machine and its use method. Background technique [0002] Mulch film is a non-degradable material that will deteriorate the soil. A large amount of residual mulch film will affect the growth of crops. Therefore, mulch film is a more distressing problem for farmers when they harvest plants and prepare the ground. It needs to be cleaned up for better planting in the second year. out of the field. [0003] For the recycling of mulch film, the machines currently used are mainly miniaturized. Due to the complicated picking conditions of the mulch machine, the mulch, straw, stubble, and soil are mixed together, and it is difficult to separate the film from the stubble, straw, and soil. The recovered mulch film has high impurity content a...

Problems solved by technology

[0003] For the recycling of mulch film, the machines currently used are mainly miniaturized. Due to the complicated picking conditions of the mulch machine, the mulch, straw, stubble, and soil are mixed together, and it is difficult to separate the film from the stubble, straw, and soil. The recovered mulch film has high impurity rate and low recovery efficiency. In addition, it is also very easy to cause stubble to block the equipment during the recovery process.
