It is an important agricultural production material. With the rapid development of agricultural production, the use of ground film has also increased rapidly. However, after years of rotational sowing, the amount of ground film remaining in the field has increased year by year, causing serious residual film pollution to the farmland. At present, most of the existing residual film recycling machines are residual film recycling machines after autumn harvest, while there are relatively few studies on pre-sowing fragmented residual film recycling machines. There is still a lack of effective cleaning methods for the broken residual film on the surface of the cotton field before sowing.

DETAILED DESCRIPTION

[0032] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0033] The purpose of the present invention is to provide a scraper-converging type device for cleaning residual film on the surface of a cotton field before sowing, so as to solve the problems existing in the above-mentioned prior art and to clean the residual film on the surface of a cotton field.

[0034] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0035] like Figure 1-Figure 4As shown, the present embodiment provides a scraper-gathering type cotton field surface residual film cleaning device before sowing, including a frame body 1, on which a driving component 2, a cleaning component 3, a spoke plate film picking roller component 4, a debris conveying component 5, a blowing film collecting component 6, a film collecting box 7 and a walking device 8 are provided, wherein the cleaning component 3, the spoke plate film picking roller component 4, the debris conveying component 5 and the blowing film collecting component 6 are sequentially arranged from front to back, so as to realize the sequential transportation of soil, residual film and other impurities, and the driving component 2 and the film collecting box 7 are installed at the upper end of the frame body 1, and the driving component 2 is located in front of the frame body 1, and the film collecting box 7 is located behind the frame body 1. The structure of each device and its working principle are further explained below.

[0036] There are two groups of cleaning components 3, which are respectively arranged on both sides of the lower front end of the frame body 1 and are symmetrically arranged. The cleaning components 3 include a cleaning sweeping disc 301 and a cleaning motor 302. The cleaning motor 302 is installed on the upper end of the cleaning sweeping disc 301. A plurality of cleaning blades 303 are evenly arranged in the circumferential direction of the lower end of the cleaning sweeping disc 301. The cleaning motor 302 is used to drive the cleaning blades 303 to rotate. The cleaning blades 303 on both sides can clean the residual film and other impurities on the surface to the middle and rear of the two.

[0037] The spoke film picking roller assembly 4 includes a spoke roller 401. The spoke roller 401 is a roller having a plurality of spokes evenly distributed on the side wall thereof. The cleaning blades 303 can clean the residual film and other impurities to the spoke roller 401. The driving assembly 2 can drive the spoke roller 401 to rotate.

[0038] The cleaning conveying assembly 5 includes two closed-loop cleaning chains 501, which are respectively arranged on the left and right sides of the frame body 1. Each cleaning chain 501 is meshed with a sprocket set, which supports the cleaning chain 501 and enables it to operate normally. The driving device is used to drive the sprocket set to rotate. A plurality of cleaning conveying shafts 502 are connected between the two cleaning chains 501, and each cleaning conveying shaft 502 is provided with a plurality of cleaning comb teeth 503. The cleaning comb teeth 503 can be the two ends of the cleaning conveying shaft 502 after the steel wire is wound around multiple circles, or can be a toothed structure protruding on the outer wall of the cleaning conveying shaft 502, as long as it can hook the residual film. The spoke plate roller 401 can also flip the residual film and convey it to the cleaning comb teeth 503 during the rotation process, and the residual film is hooked by the cleaning comb teeth 503.

[0039] The blowing film collecting assembly 6 is arranged on the side of the cleaning conveying assembly 5 away from the spoke film picking roller assembly 4, that is, the rear side of the cleaning conveying assembly 5. The blowing film collecting assembly 6 is used to blow the residual film on the cleaning comb teeth 503 into the film collecting box 7.

[0040] The walking device 8 is arranged at the lower end of the frame body 1 , and the walking device 8 is used to drive the frame body 1 to walk.

[0041] In actual use, the frame body 1 is driven by the walking device 8. During the operation of the frame body 1, the cleaning blades 303 in the two cleaning components 3 at the front end can clean the residual film and other impurities on the surface to the middle and rear of the two, and accumulate them at the spoke roller 401. Then the spoke roller 401 flips it, so that the residual film and other impurities are flipped together to the cleaning conveying component 5, and the cleaning comb teeth 503 can effectively hook the residual film in the air. As for other impurities such as soil and straw, they will fall directly to the ground. If they fall on the cleaning conveying shaft 502 or the cleaning chain 501, they will fall to the land again as the cleaning chain 501 shakes during the movement. Finally, when the residual film is transported to the rear by the cleaning comb teeth 503, the blowing film collection component 6 blows the residual film and blows it into the feed port of the film collection box 7, thereby completing the cleaning and recovery of the residual film on the surface of the cotton field.

[0042] In this embodiment, if Figure 2 As shown, the driving device includes a driving motor 201, and the driving motor 201 adopts an existing Mitsubishi servo motor, and the driving motor 201 is fixed to the frame body 1 through a motor frame.

The output shaft of the cleaning motor 302 passes through the cleaning fixed disc and is fixedly connected to the central through hole of the cleaning rotating disc. Each cleaning blade 303 is circumferentially distributed on the cleaning rotating disc. Such a connection can enable the cleaning motor 302 to be stably fixed to the cleaning fixed disc, and at the same time can also drive the cleaning rotating disc to rotate.

[0049] In this embodiment, a drum shaft is fixed at the center of the spoke drum 401, and both ends of the drum shaft are rotatably connected to the lower end of the frame body 1 through bearing seats. A drum pulley 402 is provided at each end of the drum shaft, and the drum pulley 402 and the corresponding drive shaft end pulley 2042 are connected through a drum synchronous belt transmission.
