Description

Technical Field

[0001] This invention relates to the field of agricultural machinery technology, specifically to a residual film recycling machine with a side film recycling device. Background Technology

[0002] Mulching technology has the functions of heat preservation, moisture retention, pest control, and weed control, which can effectively promote crop yield and income and is widely used in crop cultivation both domestically and internationally. However, with the increase in the area and amount of mulching, more and more residual mulch film is left in farmland. This accumulated film residue leads to a decline in soil fertility, accelerates soil compaction, and significantly affects the growth of crops the following year, hindering sustainable agricultural development.

[0003] CN112056017B discloses a residual film recycling machine with an edge film recycling device, including a frame, a film cutting disc, a film box, a gearbox, a first chain, a second chain, a third chain, a fourth chain, and an edge film recycling device. This invention allows the frame to be quickly connected to a tractor via a traction frame. As the machine moves forward, a soil-crushing roller breaks up compacted soil, the film cutting disc separates the surface film from the edge film, the front of the biomimetic soil-loosening and film-lifting component generates vibration to reduce soil cover on the edge film and decrease resistance, and the rear of the biomimetic soil-loosening and film-lifting component prevents the film from snagging or tearing. The lifted edge film is then conveyed to a conveyor belt.

[0004] The aforementioned patent has the following shortcomings: During the recycling process, the residual film recycling machine with edge film recycling device is prone to static electricity in a dry environment, and there is a certain adhesion between the residual film and the equipment parts, resulting in some residual film adhering to the inside of the equipment and not being completely collected, which reduces the recycling rate. At the same time, the residual film recycling machine has a relatively simple method of separating residual film from broken soil, and the separation effect is not good. The residual film often contains a lot of broken soil, which increases the difficulty of subsequent processing and affects the screening efficiency and recycling quality.

[0005] Therefore, it is urgent to improve the residual film recycling machine with edge film recycling device to solve the above-mentioned problems. Summary of the Invention

[0006] To address the shortcomings of existing technologies, this invention provides a residual film recycling machine with an edge film recycling device. This machine features dynamic adjustment of residual film moisture, high-frequency vibration screening, and airflow-assisted separation, significantly improving residual film recycling efficiency and purity, reducing energy consumption and maintenance costs, and offering significant economic and ecological benefits. It solves the problems encountered in existing residual film recycling machines with edge film recycling devices during the recycling process.

[0020] Compared with the prior art, the present invention provides a residual film recycling machine with an edge film recycling device, which has the following beneficial effects:

[0021] 1. This residual film recovery machine with edge film recovery device uses a piston conveying assembly to evenly spray water onto the outside of the residual film on the screen plate through atomizing nozzles, fully wetting the residual film. This helps reduce the static electricity and adhesion of the residual film, reducing its adhesion inside the equipment and improving the recovery rate. By adjusting the screw and adjusting block to change the stroke of the piston plate in the piston cylinder, the pumping frequency of the piston conveying assembly can be flexibly adjusted to adapt to different static electricity conditions, improve wetting efficiency, optimize spraying effect, and further improve the recovery efficiency of the residual film.

[0022] 2. This residual film recycling machine with edge film recycling device drives the transmission shaft and connecting frame to rotate through the linkage of the drive motor. This causes two sets of rollers to roll alternately on the upper surface of the moving plate and the buffer plate. The moving plate is driven to vibrate at high frequency under the action of the impact spring, which in turn drives the top rod and top block to impact the screen plate at high frequency, thereby achieving efficient separation of residual film. At the same time, the high-frequency vibration can accelerate the movement of residual film on the screen plate, prevent residual film from clogging at the screen holes, and help to further remove residual soil in the residual film, thereby improving screening efficiency and residual film recycling quality.

[0023] 3. This residual film recycling machine with edge film recycling device uses a drive motor as a power source. Through the meshing of transmission gears and driven gears, it drives a fan to rotate and generate airflow, accelerating the movement of the residual film on the screen plate. At the same time, through a synchronous structure, it drives the transmission shaft to rotate, realizing the linkage operation of the thrust reciprocating mechanism, piston conveying assembly and stroke changing structure. This achieves power concentration and efficient utilization, realizes dynamic adjustment of residual film wetness, high-frequency vibration screening and airflow-assisted separation, significantly improves residual film recycling efficiency and purity, reduces energy consumption and maintenance costs, and has significant economic benefits and ecological value.

[0033] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0034] Please see Figures 1 to 8This embodiment of a residual film recycling machine with a side film recycling device includes a housing 1, a feed hopper 2 fixedly connected to the top of the housing 1, and a screen plate 3 disposed inside the housing 1. A piston conveying assembly 4 extending into the housing 1 is disposed on the outside of the housing 1 for wetting the residual film, reducing static electricity and adhesion. A stroke adjustment structure 5 for flexibly adjusting the pumping frequency of the piston conveying assembly 4 is disposed on the outside of the housing 1. A thrust reciprocating mechanism 6 for driving the screen plate 3 to vibrate at high frequency is disposed inside the housing 1. A discharge port 8 is provided on the right side of the housing 1, and a discharge port 9 is provided inside the housing 1 on the lower surface of the screen plate 3. A movable wheel is rotatably mounted on the bottom of the housing 1. The feed hopper 2 is equipped with a crushing mechanism for crushing the residual film and broken soil. The crushing mechanism includes two crushing rollers rotatably mounted inside the feed hopper 2, synchronous pulleys fixedly mounted on one end of the two crushing rollers, and a belt connecting the two synchronous pulleys. A servo motor is fixedly mounted on the back of the feed hopper 2, and the output shaft of the servo motor is fixed to one end of one of the crushing rollers.

[0035] The piston conveying assembly 4 includes a piston cylinder 41 fixedly connected to the outside of the housing 1, a water tank 44 fixedly connected to the back of the housing 1, a water pumping cylinder 42 and an extraction pipe 45 fixedly connected to the left side of the piston cylinder 41, a drain cylinder 43 fixedly connected to the right side of the piston cylinder 41, a diversion pipe 48 fixedly installed on the inner wall of the housing 1, an atomizing nozzle 49 fixedly connected to the outside of the diversion pipe 48, a jet pipe 47 disposed between the drain cylinder 43 and the diversion pipe 48, and a pumping assembly disposed inside the piston cylinder 41 and extending to its outside. The water pumping cylinder 42 and the extraction pipe 45 are connected. Both the water pumping cylinder 42 and the drain cylinder 43 are rotatably connected to a one-way valve plate to prevent backflow of water during the operation of the piston conveying assembly 4. When pumping water, the one-way valve plate opens, and water flows smoothly into the piston cylinder 41; when the piston rod 411 moves in the opposite direction, the one-way valve plate closes to prevent water from flowing back to the water pumping cylinder 42 or the drain cylinder 43, thereby ensuring unidirectional water flow and improving the efficiency of pumping and draining. The one-way valve plate allows the piston plate 410 to effectively draw water from the water tank 44 into the piston cylinder 41 as the piston plate 410 slides within the piston cylinder 41, and then further deliver it to the spray system. This one-way flow design reduces energy loss during water delivery, improves pumping efficiency, and ensures that the spray system receives a sufficient water supply, thereby achieving a more uniform spray effect.

[0036] Specifically, the pumping assembly includes a piston plate 410 slidably connected inside the piston cylinder 41 and a piston rod 411 fixedly connected to the bottom of the piston plate 410 and extending to the lower surface of the piston cylinder 41. The piston rod 411 is slidably connected inside the piston cylinder 41, and the end of the piston rod 411 away from the piston plate 410 is hinged to the top of the swing rod 57. A delivery pipe 46 is fixedly connected between the drain cylinder 43 and the jet pipe 47. The jet pipe 47 is fixedly installed outside the housing 1, and a connecting pipe is fixedly connected between the jet pipe 47 and the diversion pipe 48. There are several atomizing nozzles 49, which are distributed at equal intervals outside the diversion pipe 48 and located on the upper surface of the screen plate 3. The jet pipe 47 helps to maintain stable water pressure and ensures that the water mist sprayed by the atomizing nozzles 49 is uniform and powerful.

[0037] In this embodiment, the reciprocating motion of the piston plate 410 within the piston cylinder 41 draws water from the water tank 44 through the extraction pipe 45, then transports it through the drain cylinder 43, conveying pipe 46, jet pipe 47, and connecting pipe to the distribution pipe 48. Finally, it is evenly sprayed onto the exterior of the residual film on the screen plate 3 by several equally spaced atomizing nozzles 49, significantly reducing the static electricity and adhesion of the residual film and improving wetting efficiency. The stroke of the piston rod 411 can be flexibly adjusted through the stroke changing structure 5, thereby changing the pumping frequency to adapt to the wetting requirements of the residual film under different operating conditions. The atomizing nozzles 49 are evenly distributed outside the distribution pipe 48 to ensure uniform wetting of the residual film and avoid localized insufficient or excessive wetting.

[0038] Please see Figures 4 to 6 In this embodiment, the stroke-changing structure 5 includes a mounting box 51 fixedly connected to the outside of the housing 1, an adjusting screw 52 rotatably connected to the inside of the mounting box 51, a knob 53 fixedly connected to the right end of the adjusting screw 52, ​​an adjusting block 54 threadedly connected to the outside of the adjusting screw 52, ​​a rotating seat 55 rotatably connected to the inside of the adjusting block 54, a connecting rod 56 slidably connected to the inside of the rotating seat 55 and extending to its outside, a swing rod 57 hinged to the left end of the connecting rod 56, and a transmission assembly disposed at the right end of the connecting rod 56. By setting the sliding connection between the rotating seat 55 and the connecting rod 56, and the hinged design between the hinged seat 58 and the connecting rod 56, stability and flexibility during the transmission process are ensured.

[0039] The transmission assembly includes a hinge seat 58 hinged to the right end of the connecting rod 56, a connecting rod 59 fixedly connected to the top of the hinge seat 58, an abutment spring 510 fixedly connected to the top of the hinge seat 58, and an abutment block 511 fixedly connected to the top of the connecting rod 59. A limit plate is fixedly connected to the top of the abutment spring 510, and the limit plate is slidably connected to the outside of the connecting rod 59 and abuts against the inner top wall of the mounting box 51. The abutment spring 510 is wrapped around the outside of the connecting rod 59. By setting the abutment spring 510, the impact force during the transmission process is effectively buffered, protecting the equipment from damage and extending its service life.

[0040] Specifically, a guide shaft 512 is fixedly connected inside the mounting box 51, and a limiting hole adapted to the guide shaft 512 is opened inside the adjusting block 54. The guide shaft 512 is slidably connected to the outside of the adjusting block 512 through the limiting hole. The adjusting block 54 and the rotating seat 55 are slidably connected inside the mounting box 51 through the adjusting screw 52. By setting the cooperation between the guide shaft 512 and the limiting hole inside the adjusting block 54, the stability of the adjusting block 54 during horizontal sliding is ensured, and the adjustment accuracy is improved.

[0041] In this embodiment, rotating the knob 53 drives the adjusting screw 52 to rotate, and the adjusting block 54 slides horizontally on the guide shaft 512, precisely changing the swing amplitude of the connecting rod 56, thereby adjusting the stroke of the piston rod 411 and realizing the dynamic adjustment of the pumping frequency.

[0042] Please see Figure 3 , Figure 4 and Figure 7 In this embodiment, the reciprocating mechanism 6 includes a mounting shell 61 fixedly connected to the inner wall of the housing 1, a connecting shell 62 fixedly connected to the bottom of the mounting shell 61, an impact spring 63 fixedly installed on the inner bottom wall of the connecting shell 62, a moving plate 64 fixedly connected to the top of the impact spring 63, a top rod 65 fixedly connected to the top of the moving plate 64, a top block 66 fixedly connected to the top of the top rod 65, a buffer plate 68 fixedly connected to the left side of the moving plate 64, a connecting frame 69 rotatably connected inside the mounting shell 61, and rollers 610 rotatably connected to both ends of the connecting frame 69. By setting the moving plate 64 and the connecting shell 62 to be connected by the impact spring 63, the buffer plate 68 to be fixedly connected to the left side of the moving plate 64, and the two sets of rollers 610 respectively abutting against the upper surfaces of the moving plate 64 and the buffer plate 68, a stable mechanical structure is formed, ensuring stability and reliability during high-frequency vibration. The buffer plate 68 can effectively buffer the impact force during the rolling process of the rollers 610, protecting the moving plate 64 and the connecting shell 62 from damage.

[0043] Two sets of rollers 610 abut against the upper surfaces of the moving plate 64 and the buffer plate 68, respectively. The connecting shell 62 has a movable hole adapted to the top rod 65, which is slidably connected inside the movable hole. The top block 66 abuts against the lower surface of the sieve plate 3. A limiting post 67 is fixedly connected to the inner bottom wall of the connecting shell 62. The top rod 65 is a hollow cylinder, slidably connected to the outside of the limiting post 67. By setting the top rod 65 to slide slidably connected to the movable hole inside the connecting shell 62 and the outside of the limiting post 67, the precise guidance of the top rod 65 during high-frequency vibration is ensured, preventing deviation or jamming.

[0044] In this embodiment, the drive motor 73 drives the transmission shaft 77 and the connecting frame 69 to rotate, causing the two sets of rollers 610 to roll alternately on the upper surfaces of the moving plate 64 and the buffer plate 68. This causes the moving plate 64 to vibrate at high frequency under the action of the impact spring 63, which in turn drives the top rod 65 and the top block 66 to impact the screen plate 3 at high frequency, thereby achieving efficient separation of the residual film.

[0045] Please see Figures 1 to 3 In this embodiment, the outer side of the housing 1 is provided with a linkage drive stroke change structure 5, a protruding reciprocating mechanism 6, and a linkage separation mechanism 7 for accelerating the movement of residual film on the screen plate 3. The linkage separation mechanism 7 includes a fixed shell 71 fixedly connected to the outside of the housing 1, a fan 72 rotatably connected to the inside of the fixed shell 71, a drive motor 73 fixedly installed on the outside of the housing 1, a transmission gear 74 fixedly connected to the output shaft of the drive motor 73, a driven gear 75 fixedly installed on the outside of the fan 72, a transmission shaft 77 rotatably connected to the inside of the housing 1 and extending to its outside, an eccentric block 710 fixedly connected to the left end of the transmission shaft 77, and a synchronization structure provided on the outside of the transmission shaft 77. The eccentric block 710 is rotatably connected to the outside of the housing 1 and abuts against the upper surface of the abutment block 511.

[0046] Among them, the drive gear 74 and the driven gear 75 are meshed with each other, and the end of the drive shaft 77 away from the eccentric block 710 is fixedly connected to the middle of the connecting frame 69. The eccentric block 710 and the connecting frame 69 rotate synchronously through the drive shaft 77.

[0047] Specifically, the synchronous structure includes a transmission wheel 76 fixedly connected to the outside of the transmission gear 74, a driven wheel 78 fixedly installed in the middle of the transmission shaft 77, and a synchronous belt 79 connecting the transmission wheel 76 and the driven wheel 78. A fixing block 711 is fixedly connected to the inner wall of the housing 1, and a spring 712 is fixedly connected between the fixing block 711 and the screen plate 3. There are four sets of both the fixing block 711 and the spring 712. The screen plate 3 is elastically connected to the fixing block 711 through the four sets of springs 712, forming an elastic support structure. This effectively mitigates the impact force during the high-frequency vibration of the reciprocating mechanism 6, protecting the screen plate 3 from damage. The elastic support structure allows the screen plate 3 to quickly respond to the vibration of the reciprocating mechanism 6, improving the residual film separation efficiency. Simultaneously, the elastic deformation of the spring 712 also has a certain energy storage function, helping to improve the utilization rate of vibration energy.

[0048] In this embodiment, the controller starts the drive motor 73 to synchronously drive the fan 72 and the drive shaft 77. The fan 72 is driven by the meshing of the drive gear 74 and the driven gear 75, forming a directional airflow above the screen plate 3, which significantly accelerates the separation and conveying of the residual film, avoiding accumulation and blockage. The drive shaft 77 transmits power synchronously to the eccentric block 710 and the connecting frame 69 through rotation, realizing the linkage operation of the thrust reciprocating mechanism 6, the piston conveying assembly 4 and the stroke changing structure 5, reducing intermediate transmission links and improving power transmission efficiency. The eccentric block 710 is linked with the stroke changing structure 5 through the abutment block 511, which can quickly respond to the speed change of the drive motor 73 and adjust the stroke of the piston rod 411 in real time to ensure that the residual film wetting effect matches the equipment operating status, realizing the airflow to accelerate the movement of the residual film and the high-frequency vibration of the screen plate 3, reducing the number of power sources and reducing the complexity of the equipment.

[0049] The working principle of the above embodiments is as follows:

[0050] During use, residual film and broken soil are crushed by the crushing roller inside the feed hopper 2 and enter the shell 1. The drive motor 73 is started by the controller and drives the transmission shaft 77 to rotate through the linkage separation mechanism 7. The eccentric block 710 rotates synchronously with the transmission shaft 77 and periodically presses down on the abutment block 511, causing the hinge seat 58 to move down through the connecting rod 59 to overcome the elastic force of the abutment spring 510. This pushes the connecting rod 56 to slide in the rotating seat 55, thereby driving the swing rod 57 to swing. The swing rod 57 pushes the piston rod 411 to make reciprocating linear motion in the piston cylinder 41, causing the piston plate 410 to periodically squeeze the water in the piston cylinder 41. The water is drawn in through the extraction pipe 45, transported to the jet pipe 47 through the drain pipe 43 and the conveying pipe 46, and then diverted to the diversion pipe 48 through the connecting pipe. Finally, it is evenly sprayed onto the screen plate 3 through the atomizing nozzle 49, so that the residual film is fully wetted, reducing static electricity and adhesion. When adjusting the pumping frequency, the adjusting screw 52 is rotated by turning the knob 53, causing the adjusting block 54 to move horizontally under the guidance of the guide shaft 512. The adjusting block 54 drives the rotating seat 55 and the connecting rod 56 to move synchronously, changing the sliding amplitude of the connecting rod 56 in the rotating seat 55, thereby changing the swing amplitude of the swing rod 57, and finally changing the reciprocating stroke of the piston rod 411, so as to realize the flexible adjustment of the pumping frequency and meet the residual film treatment requirements of different humidity. The transmission shaft 77 rotates under the drive of the linkage separation mechanism 7, driving the connecting frame 69 to rotate synchronously. The rollers 610 at both ends of the connecting frame 69 alternately roll and abut against the moving plate 64 and the buffer plate 68. Under the joint action of the impact spring 63, the moving plate 64 reciprocates at high frequency, driving the top rod 65 to slide at high frequency under the guidance of the moving hole and the limiting post 67, thereby causing the top block 66 to impact the screen plate 3 at high frequency, causing the screen plate 3 to vibrate at high frequency, accelerating the separation of the wetted residual film and impurities. The drive motor 73 drives the fan 72 to rotate at high speed inside the fixed shell 71 through the meshing of the transmission gear 74 and the driven gear 75, generating directional airflow to accelerate the separation and conveying of the residual film on the screen plate 3, so that the residual film can be quickly discharged through the discharge port 8. This realizes the synchronous linkage operation of the pumping frequency adjustment of the stroke change structure 5, the vibration drive of the thrust reciprocating mechanism 6, and the airflow acceleration of the fan 72. The separated residual film is discharged from the discharge port 8, and the crushed soil is discharged from the discharge port 9. The moving wheels at the bottom of the shell 1 facilitate the movement of the equipment.

[0051] The installation, connection, or setting methods disclosed in this embodiment are all common mechanical connection methods.
