Residual film recovery device and residual film recovery machine formed by same

Abstract

The invention discloses a residual film recovery device and a residual film recovery machine formed by the same. The residual film recovery device comprises a cylindrical hollow roller (4). The periphery of the outer wall of the roller (4) is provided with fingered picking teeth (6). Film withdrawing sliding blocks (3) are arranged on the picking teeth (6). The roller (4) is provided with a hollow shaft (8). A sliding sleeve (7) and chute plates (5) are arranged on the hollow shaft (8). Push-pull connecting rods (2) are arranged between the chute plates (5) and the film withdrawing sliding blocks (3). The residual film recovery device can be applied to various farmland operation machinery to form the residual film recovery machine or a combined land preparation operation machinery. Compared with the prior art, the residual film recovery device and the residual film recovery machine have simple structures and good operation effect; the problem of eliminating wound residual films and plant straws in the operating process is solved; the operation is ensured to be normally carried out; the residual film recovery device can be applied onto various residual film recovery machines and can also be integrated onto other combined land preparation operation machineries or similar operation machineries.

Description

technical field [0001] The invention relates to a residual film recovery device and a residual film recovery machine constituted by the device. Background technique [0002] At present, the application of plastic film planting technology in agricultural production has been very common, which has brought huge benefits to agriculture, but at the same time it has also brought great pollution and harm to the soil and the environment. The soil is hindered by white pollution, which hinders the growth of crops. Severe loss of support ability. Therefore, in the current production, people have fully paid attention to the recycling of the used plastic film, and concentrated recycling through various machines, so that most of the residual film in the production can be recycled, and the phenomenon of large-scale pollution has been suppressed. However, due to years of use, there will always be some mulch film fragments remaining in the soil during the recycling process, which is difficu...

Problems solved by technology

However, there is an obvious deficiency in the pick-up device in the present type of residual film recycling machine: in the operation process, there will always be residual film and plant straws that are difficult to be brushed off by the film brushing mechanism in time and are constantly wrapped around the thorns of the drum. On the nail teeth, the accumulation on the thorn-shaped nail teeth of the drum nee...
