Description

Technical Field

[0001] The present invention relates to the technical field of residual film recycling machines, and particularly to a residual film recycling machine capable of automatic cleaning. Background Art

[0002] In the mid-late 20th century, the plastic film mulching technology was widely applied globally (especially in arid regions), significantly improving crop yields and water use efficiency. However, traditional PE plastic films are difficult to degrade naturally, and long-term use results in a large number of residual film fragments. Therefore, a residual film recycling machine is needed to effectively collect the plastic films.

[0003] For example, a Chinese patent (publication number: CN109287155A) discloses a residual film recycling baling machine, which includes a frame and a film picking roller, a cutting device, a film storage device, and a compression device arranged on the frame. The film picking roller is rotatably connected to the frame and is driven to rotate by a hydraulic motor fixedly arranged on the frame. The film storage device is arranged at the rear side of the film picking roller. The upper end of the compression device is communicated with the lower end of the film storage device. The cutting device is arranged above the film picking roller and in front of the film storage device. A film lifting shovel is arranged below the film picking roller, and both ends of the film lifting shovel are fixedly connected to the frame. The cutting device of this invention can prevent the residual film from winding around the film picking roller, making it easier for the residual film to enter the film storage device, improving the operation efficiency and the residual film recovery rate. This invention also uses a compression device to bale the residual film, with a high bale density, which is more convenient for storage and transportation.

[0004] However, the film picking roller of this device cannot be adjusted in height. In actual use, the heights of plastic film mulching are different, and this device cannot adapt to different plastic film heights, which will affect the plastic film recycling effect.

Detailed implementation manners

[0021] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0022] Please refer to Figures 1 to 4, A kind of residual film recycling machine capable of automatic cleaning in this embodiment includes a box body 1. A hook 2 is fixed on the right side of the box body 1. The hook 2 is used to connect the device and a tractor. A movable door 3 is hinged on the left side of the box body 1 through a hinge. After the plastic film recycling is completed, opening the movable door 3 can quickly take out the collection box 9, which is convenient for subsequent unified collection of plastic film fragments. A driving mechanism 4 for providing stable power for the device is arranged on the top of the box body 1. Two transmission components 5 for transmitting power are arranged on the outer surface of the driving mechanism 4. Two quick-release components 6 for facilitating the user to clean the residual film are arranged on the inner top wall of the box body 1. Both transmission components 5 penetrate the top of the box body 1 and extend into the two quick-release components 6 respectively. A placement groove is formed on the inner bottom wall of the box body 1. The inner side wall of the placement groove is attached to the outer side wall of the collection box 9. The placement groove can not only improve the stability of the collection box 9 but also facilitate the user to remove the collection box 9 for unified collection of plastic film fragments. A collection box 9 is placed in the placement groove. A film raking component 8 for collecting fine residual film is arranged between the front and rear side walls in the box body 1 and on the right side of the collection box 9. A cleaning component 7 that penetrates the box body 1 and can automatically clean the film raking component 8 is arranged on the top of the box body 1. A rolling mechanism 10 for winding and collecting the residual film is arranged between the two quick-release components 6.

[0023] In addition, the driving mechanism 4 includes a first servo motor 401 fixed to the top of the box body 1. The output shaft of the first servo motor 401 is fixed with a driving shaft 402. The driving shaft 402 is rotationally connected to the top of the box body 1 through a bearing. The bearing can improve the rotational stability of the driving shaft 402.

[0024] Furthermore, each transmission component 5 includes a driving sprocket 501 fixed to the outer surface of the driving shaft 402. The driving sprocket 501 is driven to rotate by the driving shaft 402. The chain 504 transmits the power of the driving sprocket 501 to the driven sprocket 503, prompting the two driven shafts 502 to rotate synchronously. The outer surface of the driving sprocket 501 is engaged with the chain 504. The side of the chain 504 away from the driving sprocket 501 is engaged with the driven sprocket 503. The inner side of the driven sprocket 503 is fixed with a driven shaft 502 penetrating the top wall of the box body 1. The driving sprocket 501 and the driven sprocket 503 are driven by the chain 504. Using the chain drive method can take into account both long-distance transmission and transmission synchronism, and the two driven shafts 502 are symmetrically arranged before and after with the driving shaft 402 as the vertical bisector.

[0025] It can be known that each quick-release component 6 includes a stabilizing seat 601 fixed to the inner top wall of the box body 1. The driven shaft 502 penetrates through the stabilizing seat 601 and is rotatably connected to the stabilizing seat 601 through a bearing. The stabilizing seat 601 cooperates with the bearing to significantly improve the stability of the driven shaft 502. A transmission table 602 is threadedly connected to the outer surface of the driven shaft 502 and is located below the stabilizing seat 601. A dust-proof cylinder 603 extending into the stabilizing seat 601 and movably connected to the stabilizing seat 601 is fixed to the top of the transmission table 602. The dust-proof cylinder 603 is used for dust prevention and can protect the thread on the outside of the driven shaft 502. A limiting ring is fixed to the outside of the dust-proof cylinder 603. A connecting cylinder is fixed to the outer surface of the transmission table 602. A limiting portion 604 is provided inside the connecting cylinder and below the transmission table 602. A connecting block 605 is threadedly connected to the inside of the connecting cylinder and below the limiting portion 604. A limiting platform 606 extending into the transmission table 602 is fixed to the top of the limiting portion 604.

[0026] It should be further explained that each limiting part 604 includes a protective shell 6041 threadedly connected to the inner side of the connecting tube, the protective shell 6041 is used to protect the parts inside it, and the inner top wall of the protective shell 6041 is movably connected with an active gear rod 6042 that passes through the inner top wall of the protective shell 6041 and the inner bottom wall of the transmission platform 602 from bottom to top. A plane bearing is fixed on the top of the active gear rod 6042 and located in the transmission platform 602. When the transmission platform 602 moves up, it will drive the limiting part 604 to move up as a whole. , so that the plane bearing will abut against the driven shaft 502, ensuring that the torque of the driven shaft 502 will not be transmitted to the active gear rod 6042. At the same time, the plane bearing can also play a limiting role, ensuring that the active gear rod 6042 will not completely separate from the transmission platform 602. The inner top wall of the active gear rod 6042 abuts against a compression spring 6043 extending to the outside of the active gear rod 6042, and the bottom of the compression spring 6043 abuts against the inner bottom wall of the protective shell 6041. The left and right sides of the active gear rod 6042 are meshed with connecting The connecting gears 6044 are connected, and a connecting rod is fixed on the inner side of each connecting gear 6044. Each connecting rod is rotatably connected to the inner front wall and the inner rear wall of the protective shell 6041 through a bearing. The two connecting gears 6044 are meshed with a driven gear rod 6045 on the opposite sides. The connecting gears 6044 can change the direction of power transmission and convert the downward moving force of the active gear rod 6042 into the vertical moving force of the driven gear rod 6045. T-shaped grooves are opened on the left and right side walls of the inner cavity of the protective shell 6041. There are two engaging holes at the bottom of 41, and the two driven gear rods 6045 are fixed with a primary limit block 6046 extending into the T-slot and movably connected to the T-slot on the opposite sides. The two driven gear rods 6045 extend into the two engaging holes respectively, and the top of the connecting block 605 is provided with two engaging grooves respectively matched with the two driven gear rods 6045. When the driven gear rods 6045 move into the engaging grooves, the limiting effect on the connecting block 605 will be transmitted to the limiting portion 604 and the transmission platform 602.

[0027] In this embodiment, when the quick release assembly 6 moves to the bottom, due to the limiting effect of the limiting ring, the quick release assembly 6 cannot move further downward. At this time, the transmission platform 602 and the driven shaft 502 are locked again, and the transmission platform 602 will rotate with the rotation direction of the driven shaft 502. At this time, you only need to align the two connecting blocks 605 with the connecting tube to complete the automatic installation.

[0028] Please refer again Figure 1 and Figures 5 to 7, in order to facilitate the removal of the residual film, the cleaning component 7 in this embodiment includes an air pump 701 fixed to the top of the box body 1. The air pump 701 is used to drive the air flow. At the same time, the air driven by the air pump 701 is relatively small, and the air flow can only blow off the film fragments attached to the film raking component 8, without causing the film fragments to fly around. A dust-proof block 702 is fixedly connected to the right side of the air pump 701. A dust-proof net is fixed in the dust-proof block 702 for filtering dust. A connecting pipe 703 penetrating the top wall of the box body 1 is fixedly connected to the left side of the air pump 701. A nozzle 704 is fixed to the inner top wall of the box body 1. The input end of the nozzle 704 is fixedly connected to the connecting pipe 703. At the same time, during the movement of the device, it will vibrate slightly. By cooperating with the cleaning component 7 through vibration, the residual film fragments on the film raking component 8 are automatically cleaned.

[0029] Furthermore, the film raking component 8 includes an electric rotating table 801 fixed to the inner rear wall of the box body 1. The output end of the electric rotating table 801 is fixed with a connecting shaft 802. The side of the connecting shaft 802 away from the electric rotating table 801 is rotatably connected to the inner front wall of the box body 1 through a bearing. A plurality of evenly arranged film raking teeth 803 are fixed to the bottom of the connecting shaft 802. A plurality of film raking teeth 803 all extend outside the bottom of the box body 1. The rotation of the rolling mechanism 10 has loosened the soil on the surface of the farmland. Therefore, the actual resistance received by the film raking teeth 803 is relatively low.

[0030] In addition, the rolling mechanism 10 includes a second servo motor 101 fixed to the front side of the front connecting block 605. The second servo motor 101 is used to provide stable and continuous power for the overall rotation of the rolling mechanism 10. The output shaft of the second servo motor 101 penetrates the connecting block 605. The output shaft of the second servo motor 101 is fixed with a housing 102 located between the two connecting blocks 605. The housing 102 is rotatably connected to the rear connecting block 605 through a bearing. The two connecting blocks 605 and the housing 102 cooperate to achieve the effect of mutual limitation. The inner rear wall of the housing 102 is rotatably connected with a driving rod 103 through a bearing. A driving motor is fixed to the front side of the driving rod 103. The driving motor is fixed to the inner front wall of the housing 102. A plurality of driving gears 104 are fixed to the outer surface of the driving rod 103. A winding cylinder 105 is fixed to the front side of each driving gear 104. Seven connecting ropes 106 are wound around the outer surface of each winding cylinder 105. When the winding cylinder 105 rotates, it can simultaneously pull seven connecting ropes 106, thereby promoting the stable expansion and contraction of the telescopic component 108. Seven output components 107 and seven telescopic components 108 penetrating the side wall of the housing 102 are arranged between the front and rear side walls of the inner cavity of the housing 102. Seven stabilizing blocks 109 are fixed between the front and rear side walls of the inner cavity of the housing 102. The stabilizing blocks 109 are used to improve the stability of the telescopic component 108.

[0031] It should be further noted that each output component 107 includes a transmission rod 1071 rotatably connected to the front and rear side walls of the inner cavity of the housing 102 through bearings. There is a driven rod 1072 rotatably connected to the front and rear side walls of the inner cavity of the housing 102 through bearings and located outside the transmission rod 1071. The bearings can improve the stability of the transmission rod 1071 and the driven rod 1072. Transmission gears 1073 and driven gears 1074 are respectively fixed on the outer surfaces of the transmission rod 1071 and the driven rod 1072. The transmission gears 1073 are engaged with a plurality of driving gears 104. When the driving rod 103 rotates, it simultaneously drives a plurality of driving gears 104 to rotate. The driving gears 104 transmit power to the transmission gears 1073, further causing the driven gears 1074 to rotate. The driven gears 1074 are engaged with the transmission gears 1073.

[0032] It can be understood that each telescopic component 108 includes a first-stage telescopic rod 1081 engaged with the driven gear 1074. The first-stage telescopic rod 1081 penetrates the side wall of the housing 102. A connecting spring 1082 abuts against the inner bottom wall of the first-stage telescopic rod 1081. The connecting spring 1082 is in a compressed state. When the connecting rope 106 is gradually released, the second-stage telescopic rod 1083 will move outward under the action of the connecting spring 1082. The side of the connecting spring 1082 away from the first-stage telescopic rod 1081 abuts against a second-stage telescopic rod 1083 extending outside the first-stage telescopic rod 1081. Each connecting rope 106 penetrates the first-stage telescopic rod 1081 and the connecting spring 1082 and is fixed to the second-stage telescopic rod 1083. A plurality of limiting grooves are formed on the side of each stabilizing block 109 close to the first-stage telescopic rod 1081. A second-stage limiting block 1085 extending into the limiting grooves is fixed on the side of each first-stage telescopic rod 1081 away from the driven gear 1074. Through the cooperation of the second-stage limiting block 1085 and the limiting grooves, the stability of the telescopic component 108 can be significantly improved.

[0033] In this embodiment, when the driving motor drives the driving rod 103 to rotate, the driving gears 104 and the winding drum 105 on the driving rod 103 will start to rotate simultaneously. The driving gears 104 drive the transmission gears 1073 and the driven gears 1074 to rotate, driving the first-stage telescopic rod 1081 to move. The winding drum 105 will drive the connecting rope 106 to be stretched or released, and in cooperation with the connecting spring 1082, drive the second-stage telescopic rod 1083 to move.

[0034] It can be understood that storage batteries are respectively fixed on the rear side of the box body 1 and the back surface of the connecting block 605 located at the rear. This device can adjust the height of the rolling mechanism 10, facilitating the collection of plastic films at different heights. At the same time, the rolling mechanism 10 is convenient for disassembly and assembly, and it is very convenient to collect plastic films later. The film raking component 8 and the cleaning component 7 cooperate with each other to effectively collect plastic film fragments and perform automatic cleaning.

[0035] All the electrical components mentioned in the text are electrically connected to the controller and the power supply. The control method of the present invention is controlled by the controller. The control circuit of the controller can be realized by simple programming of those skilled in the art. The power supply provided by the storage battery also belongs to the common knowledge in the art. And the present invention is mainly used to protect mechanical devices, so the control method and circuit connection of the present invention will not be explained in detail hereinafter.

[0036] The working principle of the above embodiment is as follows: (1) During use, first connect the hook 2 to the tractor, start the first servo motor 401, the power output of the first servo motor 401 is transmitted to the driving shaft 402, and the power is transmitted to the two driven shafts 502 by the two transmission components 5. Since the driven rack 6045 on the limiting part 604 is located in the connecting block 605, and at the same time the two connecting blocks 605 and the rolling mechanism 10 limit each other, at this time, neither the limiting part 604 nor the transmission table 602 can rotate. When the driven shaft 502 rotates, due to the threaded connection relationship, the transmission table 602 and the limiting part 604 can only move up and down, so as to achieve the purpose of adjusting the height of the rolling mechanism 10.

[0037] (2) After the adjustment is completed, start the tractor and start the second servo motor 101. The second servo motor 101 drives the outer shell 102 to rotate, so as to drive the multiple first telescopic rods 1081 and the second telescopic rods 1083 in the outer shell 102 to rotate. By rotating the first telescopic rod 1081 and the second telescopic rod 1083, the plastic film is lifted and the plastic film is promoted to wind around the surface of the outer shell 102. The broken plastic film fragments will be blocked by the rake teeth 803, so as to realize the function of recycling the plastic film.

[0038] (3) After the plastic film recycling is completed, start the electric rotating table 801. The electric rotating table 801 drives the connecting shaft 802 and the rake teeth 803 thereon to rotate until the rake teeth 803 are completely buckled above the collection box 9, and start the air pump 701. The gas blows upward above the rake teeth 803 through the air pump 701, the connecting pipe 703 and the nozzle 704, so as to promote the plastic film fragments adhered to the rake teeth 803 to fall into the collection box 9. At the same time, reverse-start the first servo motor 401 to promote the quick-release assembly 6 to drive the rolling mechanism 10 to move upward.

[0039] (4)When the tractor moves outside the farmland and it is necessary to collect the plastic film, reverse-start the first servo motor 401 again. At this time, since the driven shaft 502 and the transmission table 602 are engaged to the deepest position, and as the driven shaft 502 approaches the inner bottom wall of the transmission table 602, the driven shaft 502 also pushes the driving tooth bar 6042 downward. Through the action of the two connecting gears 6044, the two driven tooth bars 6045 are urged to move upward. At this time, the connection between the driven tooth bar 6045 and the connection block 605 is disengaged. At this time, the driven shaft 502 drives the transmission table 602 and the limiting part 604 thereon to rotate together, and the two connection blocks 605 will drive the rolling mechanism 10 to fall off together.
