[0002] Mulch film increases warmth, retains water, and retains soil moisture and fertilizer, effectively increasing crop yields and making it a vital agricultural production resource. With the rapid development of agricultural production, the use of mulch film has also grown rapidly. However, after years of rotating sowing, the amount of mulch film remaining in the fields has increased year by year, causing serious residual film pollution in farmland. Currently, most residual film recycling machines are designed to recover whole residual film after the autumn harvest. Research on machines to recover pre-sowing residual film fragments is relatively limited, and there is still a lack of effective methods for cleaning the broken residual film on the surface of cotton fields before sowing.

[0003] In recent years, in order to treat cotton fields contaminated by residual film before sowing, domestic and foreign scholars have developed a variety of methods and equipment for recovering residual film before sowing. The main research is as follows:

DETAILED DESCRIPTION

[0032] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. 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 making creative efforts 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 the 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 Figures 1-4As shown, this embodiment provides a scraper-gathering type pre-sowing cotton field surface residual film cleaning device, 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 arranged in sequence 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 cleaning assemblies 3, one symmetrically positioned below the front end of the main frame 1. Each cleaning assembly 3 includes a cleaning disc 301 and a cleaning motor 302. The motor 302 is mounted on the upper end of the cleaning disc 301. Multiple cleaning blades 303 are evenly distributed around the lower end of the disc. The motor 302 drives the blades 303 to rotate. The cleaning blades 303 on both sides sweep residual film and other impurities toward the center and rear of the two surfaces.

[0037] The spoke film pickup roller assembly 4 includes a spoke roller 401, which is structured with multiple spokes evenly distributed around the sidewall of the roller. Cleaning blades 303 can sweep residual film and other impurities to the spoke roller 401, and the drive assembly 2 can drive the spoke roller 401 to rotate.

[0038] The cleaning conveyor assembly 5 includes two closed-loop cleaning chains 501, one on each side of the main frame 1. Each cleaning chain 501 is engaged with a sprocket assembly, which supports the cleaning chain 501 and enables its normal transmission operation. A drive device is used to drive the sprocket assembly to rotate. Multiple cleaning conveyor shafts 502 are connected between the two cleaning chains 501. Each cleaning conveyor shaft 502 is equipped with a number of cleaning comb teeth 503. The cleaning comb teeth 503 can be formed by wrapping steel wire around the ends of the cleaning conveyor shaft 502 multiple times, or they can be raised tooth-like structures fixed to the outer wall of the cleaning conveyor shaft 502, as long as they can hook the residual film. The spoke roller 401 can also flip the residual film during rotation and convey it to the cleaning comb teeth 503, where they are hooked.

[0039] The film collecting assembly 6 is provided 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 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 provided at the lower end of the frame body 1 , and is used to drive the frame body 1 to move.

[0041] In actual use, the main frame 1 is driven by the running gear 8. During operation, the cleaning blades 303 in the two cleaning assemblies 3 at the front of the main frame 1 sweep residual film and other impurities toward the center and rear of the two cleaning assemblies, where they are deposited on the spoke rollers 401. The spoke rollers 401 then toss the residual film and other impurities onto the cleaning conveyor assembly 5, where the cleaning combs 503 effectively capture the remaining film in the air. Dirt, straw, and other impurities fall directly to the ground. If they fall onto the cleaning conveyor shaft 502 or the cleaning chain 501, the vibration of the cleaning chain 501 during movement can cause them to fall back onto the ground. Finally, once the residual film has been transported to the rear by the cleaning combs 503, the film collection assembly 6 blows air onto it and blows it into the feed port of the film collection box 7, completing the cleaning and recovery of the residual film on the cotton field surface.

[0042] In this embodiment, if Figure 2 As shown, the drive device includes a drive motor 201, which uses an existing Mitsubishi servo motor and is fixed to the frame body 1 via a motor frame. The output shaft of the drive motor 201 is in driving connection with the input shaft of the drive reducer 202. When the drive motor 201 is started, it can drive the drive reducer 202 to operate. The drive reducer 202 uses an existing PLX120 precision planetary reducer. In addition, the output shaft of the drive reducer 202 is in driving connection with the drive spindle 204. The two ends of the drive spindle 204 are rotatably connected to the frame body 1 via bearing seats. A drive shaft end pulley 2042 is provided at each end of the drive spindle 204. The drive shaft end pulley 2042 can provide kinetic energy for the web film pickup roller assembly 4 and the debris removal conveyor assembly 5. In addition, a retaining ring is provided on the inner side of the drive shaft end pulley 2042, which is mounted on the groove of the drive main shaft 204. A pulley limiting cover 2043 is provided on the outer side of the drive shaft end pulley 2042, which is screwed to the end of the drive main shaft 204. The retaining ring and the pulley limiting cover 2043 work together to prevent the drive shaft end pulley 2042 from moving along the axial direction of the drive main shaft 204. The drive motor 201 is electrically connected to the power supply battery 203 to provide it with electrical energy.

[0043] In addition, a protective shell is provided on the outside of the driving assembly 2. The protective shell is located on the outside of the driving motor 201, the driving reducer 202 and the power supply battery 203, and is used to protect the various components inside them.

[0044] In this embodiment, the output shaft of the driving reducer 202 is provided with a reducer pulley through a key connection, and a driving shaft middle pulley 2041 is provided at the middle position of the driving main shaft 204. The reducer pulley and the driving shaft middle pulley 2041 are connected through a reducer synchronous belt transmission, thereby achieving the technical effect of driving the driving reducer 202 to drive the driving main shaft 204 to run.

[0045] In this embodiment, the cleaning disc 301 includes a cleaning fixed disc and a cleaning rotating disc. The cleaning rotating disc is rotatably connected to the lower end of the cleaning fixed disc, and the upper end of the cleaning rotating disc can be connected to the cleaning fixed disc through a bearing; or, the upper surface of the cleaning rotating disc is only in sliding contact with the lower surface of the cleaning fixed disc, and there is no other connection relationship. The cleaning motor 302 is installed on the upper surface of the cleaning fixed disc through the motor fixing plate. It can be understood that the motor fixing plate is fixed to the upper surface of the cleaning fixed disc by bolts, and the cleaning motor 302 is fixed to the motor fixing plate by bolts. 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. The cleaning blades 303 are 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, while at the same time it can also drive the cleaning rotating disc to rotate.

[0046] In this embodiment, the cleaning disc 301 is connected to the frame body 1 through a four-link assembly 304. The specific structure of the four-link assembly 304 is as follows:

[0047] like Figure 3 As shown, the four-bar linkage assembly 304 includes a telescopic rod 3041, a connecting rod 3042, a frame connecting plate 3043, and a motor connecting plate 3044. The telescopic rod 3041, connecting rod 3042, frame connecting plate 3043, and motor connecting plate 3044 can be considered the four connecting rod structures of the four-bar linkage assembly 304. Specifically, the frame body 1 is provided with a connecting rod fixing seat 306, and the frame connecting plate 3043 is bolted to the connecting rod fixing seat 306. The motor connecting plate 3044 is bolted to the motor fixing seat 305. Both ends of the telescopic rod 3041 and the connecting rod 3042 are hinged to the frame connecting plate 3043 and the motor connecting plate 3044. Specifically, the ends of the telescopic rod 3041 are hinged to the frame connecting plate 3043 and the motor connecting plate 3044, while the ends of the connecting rod 3042 are hinged to the frame connecting plate 3043 and the motor connecting plate 3044. Furthermore, both the frame connecting plate 3043 and the motor connecting plate 3044 are provided with hinged seats for easy hinge connection with the telescopic rod 3041 and the connecting rod 3042.

[0048] The purpose of setting up the four-link assembly 304 is to adjust the inclination angle of the sweeping disc and the cleaning blade 303, and the purpose of setting up the telescopic rod 3041 on this basis is to maintain the sweeping disc 301 and the cleaning blade 303 at the required angle.

[0049] In this embodiment, a drum shaft is fixed to the center of the spoke drum 401. Both ends of the drum shaft are rotatably connected to the lower end of the frame body 1 via bearing blocks. A drum pulley 402 is provided at each end of the drum shaft. The drum pulley 402 and the corresponding drive shaft end pulley 2042 are connected via a drum timing belt transmission. When the drive assembly 2 is in operation, the drive shaft end pulley 2042 drives the drum pulley 402 and the spoke drum 401 to rotate synchronously.

[0050] In this embodiment, if Figure 1 As shown, the sprocket assembly includes a first sprocket 504, a second sprocket 505, and a third sprocket 506. The first sprocket 504, the second sprocket 505, and the third sprocket 506 are all engaged with the cleaning chain 501 and are rotatably connected to the frame body 1 via sprocket bearing seats. The first sprocket 504 serves as a driving wheel and is connected to the drive shaft end pulley 2042 via a sprocket synchronous belt transmission. When the drive assembly 2 is in operation, the drive shaft end pulley 2042 drives the first sprocket 504 and the cleaning chain 501 to rotate. The second sprocket 505 and the third sprocket 506 primarily support the cleaning chain 501.

[0051] In addition, a synchronous belt protective shell is provided on the outside of the sprocket synchronous belt and the roller synchronous belt. The synchronous belt protective shell is fixed to the frame body 1 by screws. Its function is to prevent the sprocket synchronous belt and the roller synchronous belt from being exposed, thereby increasing the service life of the equipment.

[0052] In this embodiment, the film-blowing assembly 6 includes a fan body 601 and a fan housing 602. The fan body 601 is mounted on a fan mounting bracket 604, which is bolted to the frame body 1. The air outlet of the fan body 601 is connected to the air inlet of the fan housing 602 via a cable tie 603. The air outlet of the fan housing 602 is positioned toward the feed inlet of the film-collecting housing 7, and a gap exists between the air outlet of the fan housing 602 and the feed inlet at the rear end of the film-collecting housing 7. When the cleaning comb teeth 503 transport residual film to the gap between the fan housing 602 and the film-collecting housing 7, the fan body 601 blows the residual film into the film-collecting housing 7.

[0053] In this embodiment, the upper end of the film collecting box 7 is an open structure and is hinged with a film collecting box cover. When the work is completed, the staff can open the film collecting box cover and take out the residual film in the film collecting box 7.

[0054] In this embodiment, the traveling device 8 is an existing crawler chassis, so that it can run smoothly in uneven cotton fields.

[0055] The present invention uses specific examples to illustrate the principles and implementation methods of the present invention. The above examples are only intended to help understand the method and core concept of the present invention. At the same time, those skilled in the art will find that the specific implementation methods and application scopes may vary based on the concept of the present invention. In summary, the contents of this specification should not be construed as limiting the present invention.
