[0002] The mulching cultivation technology has the functions of heat preservation, moisture conservation, insect control, and weed control, which can effectively promote the increase of crop yield and income, and is widely used in crop planting at home and abroad. With the increase of mulching area and usage, more and more mulching film is left in the farmland. The accumulated residual film in the farmland will lead to the decline of soil fertility and accelerate soil compaction, which will greatly affect the growth of crops in the next year and is not conducive to the sustainable development of agriculture.

The invention can quickly connect the frame to the tractor through a traction frame, and when the tractor moves forward, the soil crushing roller crushes the compacted soil, the film cutting disc separates the surface film from the film edge, the front part of the bionic loosening and film lifting component can generate vibration to reduce the soil covering the film edge and reduce resistance, and the rear part of the bionic loosening and film lifting component can prevent the film from getting stuck or breaking the film, and the removed film edge is transported to the conveyor belt.

[0004] The above patent has the following shortcomings: during the recycling process, the residual film recovery machine with edge film recovery device is prone to generate static electricity in a dry environment, and there is a certain adhesion between the residual film and the equipment components, resulting in part of the residual film adhering to the inside of the equipment and unable to be completely collected, thereby reducing the recovery rate. At the same time, the residual film recovery machine has a relatively simple method for separating the residual film and the broken soil, and the separation effect is not good. A lot of broken soil is often mixed in the residual film, which increases the difficulty of subsequent processing and affects the screening efficiency and recovery quality.

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

DETAILED DESCRIPTION

[0022] 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.

[0023] See also Figures 1 to 8In this embodiment, a residual film recovery machine with an edge film recovery device comprises a housing 1, a feed hopper 2 fixedly connected to the top of the housing 1, and a sieve plate 3 arranged inside the housing 1. The housing 1 is provided with a piston conveying assembly 4 extending to the inside thereof for wetting the residual film, reducing static electricity and adhesion, and the housing 1 is provided with a stroke changing structure 5 for flexibly adjusting the pumping frequency of the piston conveying assembly 4. The housing 1 is provided with a thrust reciprocating mechanism 6 for driving the sieve plate 3 to vibrate at a high frequency. A discharge port 8 is provided on the right side of the housing 1, and a feed port 9 is provided inside the housing 1 and on the lower surface of the sieve plate 3. A moving wheel is rotatably installed at the bottom of the housing 1. A crushing mechanism for crushing residual film and broken soil is arranged inside the feed hopper 2. The crushing mechanism comprises two crushing rollers rotatably installed inside the feed hopper 2, a synchronous wheel fixedly installed at one end of the two crushing rollers, and a belt drivingly connected between the two synchronous wheels. A servo motor is fixedly installed 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.

[0024] The piston delivery 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 water discharge cylinder 43 fixedly connected to the right side of the piston cylinder 41, a diverter pipe 48 fixedly installed on the inner wall of the housing 1, an atomizing nozzle 49 fixedly connected to the outside of the diverter pipe 48, a jet pipe 47 arranged between the water discharge cylinder 43 and the diverter pipe 48, and a pumping assembly arranged inside the piston cylinder 41 and extending to the outside. The water pumping cylinder 42 and the extraction pipe 45 are connected. The inside of the water pumping cylinder 42 and the water discharge cylinder 43 are both rotatably connected with a one-way valve plate to prevent water from flowing back during the operation of the piston delivery 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 water discharge cylinder 43, thereby ensuring the one-way flow of water and improving the efficiency of pumping and draining. The setting of the one-way valve plate enables the piston plate 410 to effectively draw water from the water tank 44 to the piston cylinder 41 when sliding in the piston cylinder 41, and further transport it to the spray system. This one-way flow design reduces the energy loss of water during the transportation process, improves the pumping efficiency, ensures that the spray system can obtain sufficient water supply, and thus achieves a more uniform spray effect.

[0025] 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 one end of the piston rod 411 away from the piston plate 410 is hinged to the top end 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. A connecting pipe is fixedly connected between the jet pipe 47 and the shunt pipe 48. The number of atomizing nozzles 49 is several, and several atomizing nozzles 49 are arranged at equal intervals in sequence outside the shunt pipe 48 and located on the upper surface of the sieve plate 3. By providing the jet pipe 47, it helps to maintain the stability of the water flow pressure and ensure that the water mist sprayed by the atomizing nozzles 49 is uniform and powerful.

[0026] When this embodiment is in use, through the reciprocating movement of the piston plate 410 inside the piston cylinder 41, the water in the water tank 44 is pumped in through the extraction pipe 45, and then is transported to the shunt pipe 48 through the drain cylinder 43, the delivery pipe 46, the jet pipe 47 and the connecting pipe. Finally, it is evenly sprayed by several atomizing nozzles 49 arranged at equal intervals to the outside of the residual film on the sieve plate 3, significantly reducing the static electricity and adhesion force of the residual film and improving the wetting efficiency. The stroke of the piston rod 411 can be flexibly adjusted through the stroke change structure 5, thereby changing the pumping frequency to adapt to the wetting requirements of the residual film under different working conditions. The atomizing nozzles 49 are arranged at equal intervals outside the shunt pipe 48 to ensure uniform wetting of the residual film and avoid insufficient or excessive local wetting.

[0027] Please refer to Figures 4 to 6 In this embodiment, the stroke change structure 5 includes a mounting box 51 fixedly connected to the outside of the housing 1, an adjusting screw 52 rotatably connected inside 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 inside the adjusting block 54, a connecting rod 56 slidably connected inside the rotating seat 55 and extending to the outside thereof, a swing rod 57 hinged to the left end of the connecting rod 56, and a transmission assembly provided at the right end of the connecting rod 56. By providing the sliding connection between the rotating seat 55 and the connecting rod 56 and the hinge design between the hinge seat 58 and the connecting rod 56, the stability and flexibility during the transmission process are ensured.

[0028] The transmission assembly includes an articulated seat 58 hinged to the right end of the connecting rod 56, a connecting rod 59 fixedly connected to the top of the articulated seat 58, an abutting spring 510 fixedly connected to the top of the articulated seat 58, and an abutting block 511 fixedly connected to the top of the connecting rod 59. The top of the abutting spring 510 is fixedly connected to a limit plate, the limit plate is slidably connected to the outside of the connecting rod 59 and abuts against the inner top wall of the installation box 51, and the abutting spring 510 is connected around the outside of the connecting rod 59. The abutting spring 510 is provided to effectively buffer the impact force during the transmission process, protect the equipment from damage, and extend the service life.

[0029] Specifically, the interior of the installation box 51 is fixedly connected with a guide shaft 512, the interior of the adjustment block 54 is provided with a limiting hole adapted to the guide shaft 512, the guide shaft 512 is slidably connected to the exterior of the guide shaft 512 through the limiting hole, and the adjustment block 54 and the rotating seat 55 are slidably connected to the interior of the installation box 51 through the adjustment screw 52. By setting the guide shaft 512 to cooperate with the limiting hole inside the adjustment block 54, the stability of the adjustment block 54 during the horizontal sliding process is ensured, and the adjustment accuracy is improved.

[0030] When this embodiment is in use, the adjusting screw 52 is driven to rotate by rotating the knob 53, and the adjusting block 54 slides horizontally on the guide shaft 512 to accurately change the swing amplitude of the connecting rod 56, thereby adjusting the stroke of the piston rod 411 and realizing dynamic adjustment of the pumping frequency.

[0031] See also Figure 3 , Figure 4 and Figure 7 In this embodiment, the thrust 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 to the inside of the mounting shell 61, and rollers 610 rotatably connected to the two 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 is fixedly connected to the left side of the moving plate 64, and the two groups of rollers 610 are respectively abutted against the upper surfaces of the moving plate 64 and the buffer plate 68, a stable mechanical structure is formed to ensure stability and reliability during high-frequency vibration. The buffer plate 68 can effectively buffer the impact force of the roller 610 during the rolling process, protecting the moving plate 64 and the connecting shell 62 from damage.

[0032] Among them, two groups of rollers 610 are respectively in contact with the upper surfaces of the moving plate 64 and the buffer plate 68, a moving hole adapted to the push rod 65 is opened inside the connecting shell 62, the push rod 65 is slidably connected to the inside of the moving hole, the top block 66 is in contact with the lower surface of the sieve plate 3, and a limiting column 67 is fixedly connected to the inner bottom wall of the connecting shell 62. The push rod 65 is a hollow cylinder, and the push rod 65 is slidably connected to the outside of the limiting column 67. By setting the push rod 65 to be slidably connected to the moving hole inside the connecting shell 62 and the outside of the limiting column 67, the precise guidance of the push rod 65 during high-frequency vibration is ensured to avoid deviation or jamming.

[0033] When this embodiment is in use, the drive motor 73 is linked to drive the transmission shaft 77 and the connecting frame 69 to rotate, so that the two sets of rollers 610 roll alternately on the upper surfaces of the movable plate 64 and the buffer plate 68, pushing the movable plate 64 to vibrate at a high frequency under the action of the impact spring 63, and then driving the top rod 65 and the top block 66 to impact the screen plate 3 at a high frequency, thereby realizing efficient separation of residual film.

[0034] See also Figures 1 to 3 In this embodiment, the outside of the shell 1 is provided with a linkage driving stroke changing structure 5, a thrust reciprocating mechanism 6 and a linkage separation mechanism 7 for accelerating the movement of the residual film on the sieve plate 3. The linkage separation mechanism 7 includes a fixed shell 71 fixedly connected to the outside of the shell 1, a fan 72 rotatably connected to the inside of the fixed shell 71, a driving motor 73 fixedly installed on the outside of the shell 1, a transmission gear 74 fixedly connected to the output shaft of the driving 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 shell 1 and extending to the outside thereof, an eccentric block 710 fixedly connected to the left end of the transmission shaft 77, and a synchronous structure arranged on the outside of the transmission shaft 77. The eccentric block 710 is rotatably connected to the outside of the shell 1 and abuts against the upper surface of the abutment block 511.

[0035] The transmission gear 74 and the driven gear 75 are meshed with each other, and one end of the transmission shaft 77 away from the eccentric block 710 is fixedly connected to the middle of the connecting frame 69 , and the eccentric block 710 and the connecting frame 69 rotate synchronously through the transmission shaft 77 .

[0036] Specifically, the synchronous structure is fixedly connected to the transmission wheel 76 outside the transmission gear 74, the driven wheel 78 fixedly installed in the middle of the transmission shaft 77, and the synchronous belt 79 connected to the outside of the transmission wheel 76 and the driven wheel 78. A fixed block 711 is fixedly connected to the inner wall of the shell 1, and a spring 712 is fixedly connected between the fixed block 711 and the sieve plate 3. The number of the fixed block 711 and the spring 712 is four groups. The sieve plate 3 is elastically connected to the fixed block 711 through four groups of springs 712 to form an elastic support structure, which effectively buffers the impact force during the high-frequency vibration of the thrust reciprocating mechanism 6 and protects the sieve plate 3 from damage. The elastic support structure enables the sieve plate 3 to respond quickly to the vibration of the thrust reciprocating mechanism 6 and improve the residual film separation efficiency; at the same time, the elastic deformation of the spring 712 also has a certain energy storage effect, which helps to improve the utilization rate of vibration energy.

[0037] When this embodiment is in use, the controller starts the drive motor 73 to synchronously drive the fan 72 and the transmission shaft 77. The fan 72 is driven by the meshing transmission of the transmission gear 74 and the driven gear 75 to form a directional airflow above the sieve plate 3, which significantly accelerates the separation and transportation of the residual film and avoids accumulation and blockage. The transmission shaft 77 synchronously transmits power to the eccentric block 710 and the connecting frame 69 through rotation, thereby realizing the linkage operation of the advance reciprocating mechanism 6, the piston conveying assembly 4 and the stroke change structure 5, reducing the intermediate transmission links and improving the power transmission efficiency. The eccentric block 710 is linked with the stroke change 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 operation state, realize the airflow to accelerate the movement of the residual film and the high-frequency vibration of the sieve plate 3, reduce the number of power sources, and reduce the complexity of the equipment.

[0038] The working principle of the above embodiment is: When in use, the residual film and broken soil are crushed by the crushing roller inside the feed hopper 2 and enter the shell 1. The driving motor 73 is started by the controller to drive 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 the abutment block 511, so that the hinge seat 58 overcomes the elastic force of the abutment spring 510 and moves downward through the connecting rod 59, pushing 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, so that the piston plate 410 periodically squeezes the water in the piston cylinder 41, and the water is sucked in through the extraction pipe 45, and is transported to the jet pipe 47 through the drainage cylinder 43 and the delivery pipe 46, and then diverted to the diversion pipe 48 through the connecting pipe, and finally evenly sprayed onto the screen plate 3 through the atomizing nozzle 49, so that the residual film is fully moistened and static electricity and adhesion are reduced. When adjusting the pumping frequency, the adjusting screw 52 is driven to rotate by turning the knob 53, so that the adjusting block 54 moves horizontally under the guidance of the guide shaft 512, and 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 flexible adjustment of the pumping frequency and meet the residual film treatment with different humidity requirements. The transmission shaft 77 rotates under the drive of the linkage separation mechanism 7, driving the connecting frame 69 to rotate synchronously, and the rollers 610 at both ends of the connecting frame 69 alternately roll against the moving plate 64 and the buffer plate 68, and 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 limit column 67, and then the top block 66 impacts the sieve plate 3 at high frequency, so that the sieve plate 3 vibrates at high frequency, and accelerates the separation of the wetted residual film and impurities. The driving motor 73 drives the fan 72 to rotate at high speed in the fixed shell 71 through the meshing transmission of the transmission gear 74 and the driven gear 75, thereby generating a directional airflow, accelerating the separation and transportation of the residual film on the sieve plate 3, and allowing the residual film to be quickly discharged through the discharge port 8, thereby realizing the synchronous linkage operation of the pumping frequency adjustment of the stroke change structure 5, the vibration drive of the advance reciprocating mechanism 6, and the airflow acceleration of the fan 72.
