Description

Technical Field

[0001] The present invention relates to the technical field of ground film recovery devices, in particular to a ground film recovery device for agricultural environmental protection. Background Art

[0002] Film mulching for agricultural fields is widely used, especially in arid regions. However, if the old plastic film from years of cultivation is not promptly and effectively recycled, it can cause soil compaction and degradation, hindering crop germination, rapidly degrading soil quality and reducing land use efficiency. Furthermore, it can cause severe white pollution to the environment, becoming a major environmental hazard. Currently, the widespread use of mulch film has made its recycling a major challenge, especially since the film's edges are buried in the soil and are virtually impossible to remove. Year after year, the film residue accumulates in the soil, causing soil pollution and severely restricting crop cultivation, to the point where the land is uncultivable.

[0003] According to the published patent 202111429420.8, a mulch film recovery device for agricultural environmental protection uses a front shovel to collect the soil wrapped in mulch film, and then the mulch film is separated from the soil through a vibration crushing device, and then the larger mulch film is recovered through a transmission recovery device with a telescopic hook. Finally, the mulch film and the soil are separated by the cooperation of the rear wheel stirring mechanism and the screen drum to complete the mulch film collection work; wherein, the design of the telescopic hook enables the mulch film collected on the hook to automatically detach from the hook and fall into the collection box, without manual cleaning, which is convenient and fast, and the rear wheel stirring mechanism uses the rolling of the rear wheel to drive the stirring scraper to rotate in the screen drum to complete the stirring work. The design is exquisite and cost-saving; in addition, the rotating front wheel utilizes a fixed corner leg and a rotating corner leg with a rotating connection. The position of the front wheel can be adjusted by adjusting the rotating corner leg to realize the folding or lowering of the front wheel, which is easy to operate.

[0004] According to the published patent 202321840761.9, it includes a recovery device body and a film-shoveling guide plate fixedly installed in front of the bottom surface of the recovery device body; the left and right sides of the bottom surface of the recovery device body are symmetrically arranged with movable guide wheels on bearings for rotation; it also includes: a ground film winding roller is arranged at the rear of the top surface of the recovery device body through bearing rotation; wherein, the front and rear sides of the middle part of the recovery device body are both provided with cleaning rollers for leveling the ground film through bearing rotation; wherein, the driving motor on the right side of the rear of the recovery device body is fixedly connected to the movable guide wheel. In the process of realizing the invention, the inventor found that at least the following problems in the prior art have not been solved. The ground film is positioned by the ground film winding roller inside the recovery device body, and the ground film is cleaned by the cleaning roller and the knocking flip rod during the oblique transportation, and the wrinkles formed on the ground film due to long-term covering are smoothed out, which solves the problem that the ground film cannot be used twice.

[0005] According to the published patent 202420114192.8, a ground film recovery device for agricultural environmental protection includes a ground film recovery casing, the interior of the ground film recovery casing includes a film inlet and a film storage tank, and a baffle is fixedly installed inside the ground film recovery casing, wherein the film inlet and the film storage tank are separated by the baffle, and a metal roller is arranged inside the film inlet, wherein the metal roller includes a central rotating shaft 1, and the surface of the metal roller is provided with U-shaped metal distributed in a central array, and a square hole is opened on the right upper surface of the ground film recovery casing, and a motor is provided on the right upper surface of the ground film recovery casing and on one side of the square hole. In the process of realizing the invention, the inventor found that at least the following problems in the prior art have not been solved. By starting the motor, the metal roller and the roller brush are driven to rotate counterclockwise, thereby rolling up the ground film laid on the ground, and after being cleaned by the roller brush, it is stored in the film storage tank. This design can efficiently recycle and clean the ground film, solving the problem that the ground film cannot be reused.

[0006] According to the published patent 202421042628.3, an adjustable agricultural environmental protection ground film recovery device includes a recovery box, a push-pull rod, a box bracket, a roller, a closed door, a ground film recovery mechanism, an adjustable winding assembly, a ground film fixing assembly and a ground film cleaning mechanism. The ground film recovery mechanism includes a bottom support plate, a fixed vertical plate, a winding motor, a telescopic rod, a winding frame, a telescopic hydraulic rod, a mobile vertical plate, a slide groove, a slider, a rotating support, a rotating splint and a clamping spring. The ground film cleaning mechanism includes a top support plate, a support shaft, a lifting hydraulic rod, Brush support, debris removal brush, rotating motor and fan. In the process of realizing the invention, the inventor found that at least the following problems in the prior art have not been solved. By turning on the telescopic hydraulic rod to make it extend and retract, the two sets of winding frames move accordingly to adjust the spacing to adapt to different widths of ground films. At the same time, the winding motor can be turned on to automatically rewind and recycle the ground film; by turning on the lifting hydraulic rod to adjust the distance between the debris removal brush and the supporting shaft, and at the same time turning on the rotating motor to clean and remove debris from the surface of the ground film between them, the problem of the ground film not being able to be cleaned is solved.

[0007] During use, although the traditional agricultural environmental protection ground film recovery device can clean the ground film surface during the ground film recovery process, there will still be a large amount of lumped soil on the ground film surface after cleaning that cannot be cleaned off, and the moist soil attached to the ground film surface cannot be cleaned off during the ground film recovery process. Moreover, when only a roller brush is used to clean the moist soil, the more it is cleaned, the dirtier it will become, resulting in a relatively poor cleaning effect of the ground film recovery device during the ground film recovery process. For this reason, a new technical solution needs to be designed to solve this problem. Summary of the Invention

[0028] As a preferred embodiment of the present invention, the external thread of the second bidirectional threaded screw is connected to a scraper, and an air outlet hole inclined downward at an angle of 30 degrees is opened on one side of the scraper.

[0031] When the ground film cleaning roller and crushing mechanism are cleaning the ground film surface, the air compressor will compress the external air and store it in the air tank. Since heat is generated during the air compression process, the external air will be heated to 60-80 degrees.

At this time, the two driven gears will drive the two second bidirectional threaded screws to rotate clockwise and counterclockwise inside the two ground film pretreatment mechanisms, so that the two second bidirectional threaded screws drive the two sets of scrapers to move back and forth on the ground film, thereby cleaning the agglomerated soil on the ground film and cleaning other debris attached to the surface of the ground film. At the same time, it can also flatten the folded ground film on both sides of the ground film. In this process, the hot air in the air tank of the air compressor will be transported to the inside of the air guide pipe, and then the air guide pipe will transport the hot air to the hose, and then the hose will transport the hot air to the inside of the scraper, and finally there is an air outlet to spray the hot air, so that the moist soil on the front and back of the ground film can be preliminarily dried, and the soil or other objects attached to the surface of the ground film can be blown away, which is conducive to further improving the cleaning effect during ground film recycling.

[0053] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0054] In the description of the present invention, it should be understood that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore should not be understood as limiting the present invention.

[0055] Example 1: An agricultural environmental protection film recovery device, see Figures 1 to 13 , comprising two carriers 1, the upper surfaces of one side of the two carriers 1 are respectively fixedly connected with support plates 11, and further comprising:

[0056] There are two ground film cleaning rollers 2, which are symmetrically installed with the ground film. The two ends of the ground film cleaning rollers 2 are rotatably connected to the inside between the two support plates 11, and are used to roll and brush clean the soil attached to the surface of the ground film;

[0057] The two mulch film cleaning rollers 2 also include:

[0058] A first transmission gear 21, the shaft of which movably passes through the interior of the support plate 11 and is fixedly connected to one end of the mulch cleaning roller 2, the toothed end of the first transmission gear 21 meshes with one end of the second chain 22, and the other end of the second chain 22 meshes with the toothed end of the second transmission gear 12;

[0059] It should be understood that in actual use, the dual-axis motor 16 will drive the second transmission gear 12 to rotate, and then the second transmission gear 12 will drive the two first transmission gears 21 to rotate through the second chain 22. At this time, the two first transmission gears 21 will drive the two mulch cleaning rollers 2 to rotate, so that the soft hairs on the two mulch cleaning rollers 2 can simultaneously clean the soil attached to the front and back sides of the mulch, which is conducive to improving the efficiency of the mulch in cleaning the soil attached to the surface;

[0060] The outer diameter of the second transmission gear 12 is three times the outer diameter of the first transmission gear 21;

[0061] It should be understood that in actual use, when the second transmission gear 12 rotates one circle, the first transmission gear 21 rotates three circles, thereby making the speed of the ground film when winding slower than the speed of the ground film when cleaning, which is conducive to improving the adequacy of the ground film surface when cleaning;

[0062] It is worth noting that, see Figures 8 to 11 , crushing mechanism, there are six groups of crushing mechanisms, which are respectively installed inside the six track grooves 3 on the outer surface of the film cleaning roller 2. The crushing mechanism is used to crush the soil condensed on the surface of the film. The crushing mechanism includes:

[0063] The crushing assembly includes a crushing sleeve 31 and a crushing extension plate 32. One end of the crushing extension plate 32 is fixedly connected to a first magnet block 33. The other end of the crushing extension plate 32 is slidably connected to the inner wall of the crushing sleeve 31. A second magnet block 34 is fixedly installed inside the crushing sleeve 31. A third magnet block 35 is fixedly connected inside the crushing sleeve 31.

[0064] For details, see Figure 11 The magnetic force of the first magnet block 33 is twice that of the second magnet block 34. The end of the first magnet block 33 installed inside the six crushing extension plates 32 on one film cleaning roller 2, which is away from the second magnet block 34, is a cathode. The end of the first magnet block 33 installed inside the six crushing extension plates 32 on the other film cleaning roller 2, which is away from the second magnet block 34, is anode. When both crushing extension plates 32 are in contact with the film, the two symmetrical first magnet blocks 33 will be adsorbed, so that one end of the two crushing extension plates 32 is adsorbed together, so that the film is fully contacted. The magnetic forces at the opposite ends of the second magnet block 34 and the third magnet block 35 are cathode and anode, respectively, so that the second magnet block 34 and the third magnet block 35 can generate an adsorption force. When the two crushing extension plates 32 are separated, the crushing extension plate 32 will retract into the inside of the crushing sleeve plate 31 again under the condition that the second magnet block 34 and the third magnet block 35 generate an adsorption force.

[0065] It should be understood that in actual use, when the crushing extension plates 32 on both sides of the ground film come into contact with the ground film, the crushing extension plates 32 on the two ground film cleaning rollers 2 will generate an adsorption force. During this process, the crushing extension plates 32 will move outward inside the crushing sleeve 31, so that the crushing surfaces of the two crushing extension plates 32 are clamped on the surface of the ground film.

[0066] The guide assembly includes a guide rod 36 and a guide block 37. Both ends of the guide rod 36 are fixedly connected to the inner wall of the track groove 3. The guide block 37 is sleeved on the outer surface of the guide rod 36 and is slidably connected to the inner wall of the track groove 3.

[0067] It should be understood that in actual use, when the guide block 37 reciprocates within the track groove 3, the guide rod 36 will limit the position of the guide block 37, thereby improving the stability of the guide block 37 when moving within the track groove 3;

[0068] The transmission assembly includes a connecting arm 38 rotatably connected to the upper surface of the guide block 37, the other end of the connecting arm 38 is rotatably connected to a transmission arm 39, the other end of the transmission arm 39 is fixedly connected to the mounting end of the first bevel gear 40, the toothed end of the first bevel gear 40 is meshed with the toothed end of the second bevel gear 41, the shaft portion of the first bevel gear 40 is rotatably connected to one end of the connecting plate 42, the other end of the connecting plate 42 is fixedly connected to the end surface of the film cleaning roller 2, one side of the second bevel gear 41 is fixedly connected to a gear ring 43, the toothed portion of the gear ring 43 is meshed with one end of the first chain 44;

[0069] The inner ring of the second bevel gear 41 is fixedly connected to the outer ring of the connecting bearing 45, and the inner ring of the connecting bearing 45 is fixedly connected to the outer surface of one end of the ground film cleaning roller 2. The other end of the first chain 44 is installed on the gear ring 43 at one end of the other ground film cleaning roller 2;

[0070] It should be understood that in actual use, when the soft hairs on the two mulch cleaning rollers 2 are simultaneously cleaning the soil attached to the front and back sides of the mulch, the first chain 44 will drive the gear ring 43 to rotate, and the gear ring 43 will drive the second bevel gear 41 to rotate. At this time, the second bevel gear 41 will drive the connecting bearing 45 to rotate on the mulch cleaning roller 2, and the second bevel gear 41 will also drive the first bevel gear 40 to rotate. The shaft of the first bevel gear 40 will rotate on the connecting plate 42, so that the shaft of the first bevel gear 40 drives one end of the transmission arm 39 to make a circular motion. At this time, the transmission The other end of the arm 39 drives the connecting arm 38 to reciprocate on the guide block 37, and the connecting arm 38 drives the guide block 37 to reciprocate outside the guide rod 36 and inside the track groove 3, so that the guide block 37 drives the crushing sleeve 31 and the crushing extension plate 32 to reciprocate, and then the crushing extension plates 32 on both sides of the ground film cooperate to reciprocate along the two ends of the ground film cleaning roller 2, thereby generating a rubbing force on the agglomerated soil attached to the surface of the ground film, crushing the agglomerated soil, which is beneficial to improving the cleaning effect during the ground film recovery process;

[0071] It is worth mentioning that see Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 and Figure 13 , jet cleaning mechanism, the jet cleaning mechanism includes jet holes 5, the jet cleaning mechanism is provided with six groups, and is respectively installed on one side of the six track grooves 3, and is connected to the gas flow channel 54 inside the film cleaning roller 2. Each group of jet holes 5 consists of two groups of holes symmetrically arranged and at an angle of 60 degrees to the gas flow channel 54. The jet cleaning mechanism is used to dry and clean the wet soil and clean the crushed soil;

[0072] The diameter of the air jet hole 5 is 2 mm, which can increase the pressure of the gas ejected from the film cleaning roller 2, thereby enhancing the effect of cleaning the soil on the film surface;

[0073] The jet cleaning mechanism also includes;

[0074] A rotary joint 51, one end of which is rotatably connected to the other end of the mulch cleaning roller 2. The other end of the mulch cleaning roller 2 is in communication with the interior of the rotary joint 51 and the interior of the rotary joint 51. The other end of the rotary joint 51 is sealed with an air pipeline 52. One end of the air pipeline 52 is sealed with an air outlet control valve of an air compressor 53.

[0075] The rotary joint 51 is composed of a pipe joint and a sealed bearing. The outer ring of the sealed bearing is sealed to the inner wall of the pipe joint, and the inner ring of the sealed bearing is sealed to the outside of one end of the film cleaning roller 2. The design of the rotary joint 51 can prevent the gas pipeline 52 from rotating with the film cleaning roller 2 during rotation, thereby preventing the gas pipeline 52 from being entangled and broken.

[0076] It should be understood that in actual use, when the ground film cleaning roller 2 and the crushing mechanism are combined to clean the surface of the ground film, the air compressor 53 will compress the outside air and store it in the air tank. Since heat is generated during the air compression process, the outside air will be heated to 60-80 degrees. The gas in the air tank of the air compressor 53 is then transported to the interior of the rotary joint 51 by the air pipeline 52, and the hot air is then introduced into the interior of the ground film cleaning roller 2 by the rotary joint 51. The hot air is then blown out from the middle of the ground film to both sides by the air jet holes 5 on the ground film cleaning roller 2, thereby blowing away the soil attached to the ground film while quickly drying the moist soil on the ground film, which is beneficial to further improve the cleaning effect during the ground film recycling process.

[0077] It is worth noting that, see Figures 3 to 5 One side of the second transmission gear 12 is fixedly connected to one end of the mounting shaft 13, the middle of the mounting shaft 13 is rotatably connected to one end of the fixing plate 14, the other end of the fixing plate 14 is fixedly connected to the carrier 1, the other end of the mounting shaft 13 is fixedly connected to one end of the extension column 151, the other end of the extension column 151 is slidably connected to the inner wall of the sleeve column 15, the other end of the sleeve column 15 is fixedly connected to one output end of the dual-axis motor 16, and the other output end of the dual-axis motor 16 is fixedly connected to one side of a winding roller chuck 17;

[0078] The winding roller chuck 17 is rotatably connected to one end of the support arm 18, and the other end of the support arm 18 is slidably connected to the inner wall of the mounting base plate 19 and is connected to the toothed portion of the first bidirectional threaded screw 191. Both ends of the first bidirectional threaded screw 191 are rotatably connected to the inner wall of the mounting base plate 19, one end of which movably passes through one side of the mounting base plate 19 and is fixedly connected to the middle of the turntable 192. The mounting end of the dual-axis motor 16 is fixedly connected to one side of a support arm 18;

[0079] It should be understood that in actual use, when the sizes of the recovery rollers used for film recovery are different, first place the two ends of the film recovery roller between the two winding roller chucks 17, and then rotate the turntable 192 so that the turntable 192 drives the first bidirectional threaded screw 191 to rotate clockwise, thereby allowing the first bidirectional threaded screw 191 to drive the two support arms 18 to move relative to each other, so that the winding roller chuck 17 on the support arm 18 clamps and fixes the film recovery roller. When the support arm 18 moves, the dual-axis motor 16 will move together. At this time, one output end of the dual-axis motor 16 will drive the sleeve column 15 to move outside the extension column 151, thereby achieving the fixation of film recovery rollers of different sizes without affecting the normal operation of other transmission components.

[0080] It is worth noting that see Figure 1 and Figure 3 A linkage mechanism is installed between the first chain 44 and the second chain 22. The linkage mechanism includes a linkage rod 23, a large gear 24 and a small gear 25. The linkage rod 23 is rotatably connected to one side of the support plate 11. The centers of the large gear 24 and the small gear 25 are fixedly connected to the two ends of the linkage rod 23 respectively. The toothed end of the large gear 24 is engaged with the toothed end of the second chain 22, and the toothed end of the small gear 25 is engaged with the toothed end of the first chain 44.

[0081] It should be understood that in actual use, when the second transmission gear 12 drives the two first transmission gears 21 to rotate through the second chain 22, the second chain 22 will also drive the large gear 24 to rotate, and then the large gear 24 drives the linkage rod 23 to rotate on the support plate 11, and the linkage rod 23 will also drive the small gear 25 to rotate, so that the small gear 25 drives the first chain 44 to rotate, so that one motor can drive multiple transmission mechanisms to rotate at the same time, saving the cost of the ground film recovery device during production and manufacturing, and reducing the cost and difficulty of subsequent maintenance of the ground film recovery device.

[0082] It is worth emphasizing that see Figure 1 、 Figure 2 and Figure 12, two ground film pretreatment mechanisms 6 are fixedly installed on the support plate 11, and the two ground film pretreatment mechanisms 6 are internally rotatably connected with a second bidirectional threaded screw 61, one end of the second bidirectional threaded screw 61 movably passes through one end of the ground film pretreatment mechanism 6, and is fixedly connected to the center of the driven gear 62, and the toothed end of the driven gear 62 is engaged with a driving gear 63, and the center of the driving gear 63 is fixedly connected to the output end of the servo motor 68, and the mounting end of the servo motor 68 is fixedly connected to one side of the support plate 11, and the external thread of the second bidirectional threaded screw 61 is connected to a scraper 64, and an air outlet hole 65 inclined downward at an angle of 30 degrees is provided on one side of the scraper 64, and one end of the scraper 64 is sealed with a hose 66, and the other end of the hose 66 is sealed to one end of the air guide pipe 67, and the other end of the air guide pipe 67 is sealed to another air outlet control valve of the air compressor 53;

[0083] It should be understood that in actual use, when the ground film is being recycled, it will pass through the two ground film pretreatment mechanisms 6. During this process, the output end of the servo motor 68 will drive the driving gear 63 to rotate, and then the driving gear 63 will drive the two driven gears 62 to rotate. At this time, the two driven gears 62 will drive the two second bidirectional threaded screws 61 to rotate clockwise and counterclockwise inside the two ground film pretreatment mechanisms 6, so that the two second bidirectional threaded screws 61 drive the two sets of scrapers 64 to move back and forth on the ground film, thereby cleaning the agglomerated soil on the ground film. The hot air is then blown away by the blower 64, and then the hot air is blown away by the blower 65. The hot air is then blown away by the blower 66, and then the blower 66 is blown away by the blower 65. The hot air is then blown away by the blower 65, and then the hot air is blown away by the blower 65.

[0084] It should be noted that the diameter of the air outlet 65 is 3 mm, and the rotation speed of the servo motor 68 is three times that of the dual-axis motor 16, thereby preventing the ground film from being transported too fast and causing part of the ground film to not be cleaned by the scraper 64;

[0085] It should also be noted that one end of the carrier 1 is rotatably connected to the first film guide roller 101, and the top of the carrier 1 is rotatably connected to the second film guide roller 102. The first film guide roller 101 and the second film guide roller 102 are the same size. When the ground film is recovered, one output end of the dual-axis motor 16 will drive the ground film recovery roller on the winding turntable 192 to rotate. At this time, the ground film will be wound on the ground film recovery roller. During this process, the ground film will be transported by the first film guide roller 101 and the second film guide roller 102. The first film guide roller 101 and the second film guide roller 102 play a role in limiting the ground film.
