Background technique

The laying of plastic film can prevent the temperature from being too high in summer, increase the temperature and preserve moisture in winter, but with the continuous use of plastic film, the content of residual film in the soil increases, resulting in a downward trend in agricultural crop yield. Relevant domestic scientific research institutes have developed various types of residual film recovery machines based on the relevant technologies of residual film recovery. However, there are still various deficiencies in today's various residual film recycling machines that need to be improved. Common problems include incomplete collection of plastic film, high rate of damage, serious phenomenon of soil clumps mixed with straw, and excessive reliance on labor.

With the continuous increase of the area and years of use of agricultural mulch films in my country, the content of mulch film residues in all farmlands is also increasing. Since the raw materials for the production of agricultural mulch films in my country are basically expanded polystyrene, polyethylene or polypropylene, etc. , it is almost impossible to degrade itself under natural conditions, and more and more agricultural mulch residues will have many adverse effects on the farmland ecological environment and agricultural production. Relevant issues have also been raised in Gan Furong's "Current Situation and Development Trend of Plastic Film Recycling Machinery in my country" [J]. Agricultural Engineering, 2019, 9(09): 23-26. Therefore, the recycling of residual film is particularly important.

CN202222979572.1 discloses a residual mulch film collection roller assembly and a residual mulch film recovery machine, but this device cannot complete automatic film unloading and related actions, and there is a possibility that the needle will be stuck, the film unloading is incomplete, and the film-soil separation is not complete And other issues.

The traction frame of this residual film recycling machine is connected to the tractor, and the drive shaft 12 is connected to the power output shaft of the tractor, and the power of the tractor provides power to the bellows 1 and the whole implement through the drive shaft 12 . The driving shaft 12 is connected with the large pulley 14 to provide power for the large pulley 14 to rotate. The large pulley 14 is connected with the small pulley 18 through the belt 17. The speed of the large pulley 14 and the small pulley 18 increases through the radius difference, so that the bellows 1 The multiplied speed increase of the rotating speed on the fan spindle provides greater power for the bellows 1, and the wind blows out from the air outlet 25 to blow away the impurities on the mulching film, preparing for the next step of starting and closing the film.

This implement advances forward, and the mulching shovel 8 carries out breaking stubble and breaking the soil at the burrowing 7cm place and then the mulch is separated from the land.

The power of the driving shaft 12 of the implement is output to the gear pump 19 through the transmission shaft 11. The gear pump 19 works and transmits the power to the hydraulic motor 15 by the hydraulic oil. Power, so that the segmented film roll 16 rotates to take up the film picked up by the film picker 26, and then completes the film wrapping action.
