Description

Technical Field

[0001] This solution belongs to the field of agricultural machinery technology, specifically involving a segmented integrated roller for waste removal and transmission used in a combined machine for residual film recycling. Background Technology

[0002] The application of plastic film mulching technology has become very widespread, bringing huge benefits to agriculture. However, the white pollution caused by residual film in the soil has also become a serious problem, causing significant pollution and harm to the soil and environment. White pollution hinders crop growth and severely impairs the soil's nutrient supply capacity. To solve this problem, combined plastic film recycling machines have emerged.

[0003] See the existing publication (announcement) document CN218859941U, which discloses a replaceable agricultural residual film packaging box for a residual film recycling machine. The box includes a box body, and a second belt packaging mechanism is installed on the side of the box door facing the box body. The second belt packaging mechanism includes a tension adjusting belt roller, a drive belt roller, a secondary belt roller, a belt angle adjusting roller, and a friction packing belt that is rotatably connected to the left and right side walls of the box door. The secondary belt roller and the tension adjusting belt roller have the same roller structure, both including a spiral main shaft and a right spiral auger plate, a right spiral auger for removing debris, an intermediate support sleeve, a left spiral auger plate, and a left spiral auger for removing debris, all mounted on the spiral main shaft.

[0004] The auger inside the aforementioned packing film box supports the corresponding friction packing straps one and two while discharging impurities to both sides. However, due to the varying sizes of different models of packing film boxes, the installation dimensions of the auger (such as the length of the spiral spindle, the auger cover plate, and the radial dimensions of the auger) are difficult to match with the internal space of the film box, making it difficult for the auger to be adapted to different models of packing film boxes. Utility Model Content

[0005] The purpose of this solution is to provide a segmented integrated impurity removal and transmission roller for use in a combined residual film recycling machine, in order to solve the problem that the installation dimensions of existing impurity removal augers are difficult to adapt due to the different sizes of the packaging film boxes.

[0006] To achieve the above objectives, this solution provides a segmented integrated roller for residual film recycling combined operation machine, including a discharge auger, which is composed of multiple auger units; each auger unit includes a spiral main shaft and spiral auger plates respectively disposed on the spiral main shaft; adjacent auger units are connected by detachable connectors, which enable the spiral main shafts of adjacent auger units to be coaxially connected, and enable the spiral auger plates of adjacent auger units to form a continuous spiral structure after splicing.

[0007] The principle and effect of this solution are as follows: By designing the auger for removing debris as a detachable structure composed of multiple auger units, and using detachable connectors to achieve coaxial docking of the spiral main shafts of adjacent auger units and continuous splicing of the spiral auger plates, when faced with packing film boxes of different models and sizes, different specifications and quantities of auger units can be selected for combination and installation according to the internal space dimensions of the film box. Unlike traditional debris removal augers, it is not subject to fixed size restrictions, which solves the problem that the installation size of existing debris removal augers is difficult to adapt due to the different sizes of packing film boxes, and improves the versatility of debris removal augers for different packing film boxes.

[0008] Furthermore, the connector includes a flat key, a retaining ring, and a nut. The flat key is embedded in the keyway at the mating end of the adjacent auger central shaft. The retaining ring is fitted on the spiral spindle and located at the mating gap of the adjacent auger units. The nut is threaded to the end of the spiral spindle, and the retaining ring is pressed against the mating end face of the adjacent auger units by the nut.

[0009] The principle and effect of this solution are as follows: A connecting component consisting of a flat key, a retaining ring, and a nut is used. The flat key is embedded in the keyway at the mating end of the central shaft of adjacent augers to achieve circumferential fixation, preventing relative rotation of the auger units. The retaining ring is fitted onto the screw shaft at the mating gap. The nut is threaded to the end of the screw shaft. After tightening the nut, the retaining ring is pressed against the mating end face of the adjacent auger units, thereby achieving axial limitation and ensuring a tight connection between adjacent auger units and coaxial mating of the screw shafts. This detachable connection method not only ensures the structural stability of the assembled augers but also facilitates the quick disassembly, replacement, and assembly of auger units of different specifications according to the different sizes of packaging film boxes.

[0010] Furthermore, the auger unit includes a left-handed auger unit and a right-handed auger unit, which are symmetrically distributed along the central axis of the main helical shaft.

[0011] The principle and effect of this scheme are as follows: the auger unit is designed as a left-handed auger unit and a right-handed auger unit, and they are symmetrically distributed along the central axis of the main spiral shaft. Utilizing the opposite spiral thrust generated by the left-handed and right-handed spiral structures, during the rotation of the impurity removal auger, the left-handed auger unit pushes the impurities on one side to one end along the spiral direction, while the right-handed auger unit pushes the impurities on the other side to the other end, thereby allowing the impurities to be discharged to both sides respectively.

[0012] Furthermore, it also includes a cleaning component, the cleaning component comprising:

[0013] A high-pressure nozzle is located on one side of the debris removal auger, with the outlet end of the high-pressure nozzle facing the debris removal auger.

[0014] A drive unit is provided to drive a high-pressure nozzle to move along the length of the auger. The drive unit includes a cylinder, an air pump, a cam, and a guide rail. The high-pressure nozzle is mounted on the piston rod of the cylinder. The cam is coaxially and fixedly connected to the end of the auger. The air pump is located inside the membrane housing. The cam is used to intermittently collide with the air pump. The air outlet of the air pump is connected to the air inlet of the cylinder through a pipe. A pressure relief valve is provided on the guide rail. One end of the pressure relief valve is connected to the air inlet of the cylinder through a pipe, and the other end is connected to the high-pressure nozzle through a pipe.

[0015] The principle and effect of this solution are as follows: During the operation of the auger, impurities such as grass roots and damp soil mixed with residual film are adhesive, causing them to accumulate on the auger surface. If not cleaned in time, these adhering impurities will clog the spiral gap, increasing operating resistance and reducing impurity removal efficiency. Long-term accumulation may also cause equipment jamming or accelerated wear, affecting the continuity of residual film recovery. Therefore, it is necessary to remove the impurities adhering to the auger to ensure stable equipment operation. Therefore, in this solution, during the operation of the auger, a cam coaxially fixed to its end rotates synchronously with the auger, intermittently colliding with the air pump. When the air pump is collided, it generates gas, which is transported through a pipeline to the cylinder, pushing the cylinder piston rod to move the high-pressure nozzle along the guide rail. Simultaneously, the high-pressure gas is sprayed from the high-pressure nozzle towards the auger through a pressure relief valve and pipeline, using the high-pressure airflow to sweep away the grass roots, damp soil, and other impurities adhering to the auger surface, preventing impurities from clogging the spiral gap and avoiding long-term accumulation that affects residual film recovery.

[0016] Furthermore, a guide rail slider is slidably provided on the guide rail along the length direction of the auger for removing debris. The high-pressure nozzle is provided on the guide rail slider. The pressure relief valve is a push-button type pressure relief valve. The guide rail slider is used to press the pressure relief valve. The cylinder is provided with a reset spring for resetting the cylinder piston. One end of the reset spring is fixedly connected to the piston, and the other end is fixedly connected to the cylinder body.

[0017] The principle and effect of this solution are as follows: By mounting the high-pressure nozzle on the guide rail slider of the linear motor, it provides positioning and guidance for the high-pressure nozzle's movement on the guide rail. When the piston rod of the cylinder extends to its limit position, the guide rail slider contacts and presses the pressure relief valve, causing the gas in the cylinder to pass through the pipe and the pressure relief valve, and finally be ejected from the high-pressure nozzle. This utilizes the gas generated by the air pump to drive the cylinder, moving the high-pressure nozzle, and the pressure relief valve releases pressure from the cylinder, allowing the gas to clean the impurity removal auger. Simultaneously with the cylinder pressure relief, the piston assembly resets under the preload of the spring, and the piston rod slowly retracts to its initial position. After the guide rail slider moves away from the pressure relief valve, the air pump continues to generate gas and send it into the cylinder, repeating the cycle to clean the impurity removal auger.

[0018] Furthermore, the spray axis of the high-pressure nozzle forms a perpendicular angle with the axis of the debris removal auger; the high-pressure nozzle is located below the transverse symmetrical axis of the debris removal auger.

[0019] The principle and effect of this solution are as follows: the spray axis of the high-pressure nozzle is set to a vertical angle with the axis of the debris removal auger, and the high-pressure nozzle is placed below the transverse symmetrical axis of the debris removal auger, so that the high-pressure airflow can impact the surface of the debris removal auger, thereby blowing away the grass roots, wet soil and other impurities adhering to the auger.

[0020] Furthermore, the number of the debris removal augers is two symmetrically arranged, and both debris removal augers are driven and connected to friction packing straps; the number of the cleaning components is two sets, and they are respectively arranged on both sides of the two debris removal augers.

[0021] The principle and effect of this solution are as follows: the residual film is collected by using two augers to drive and connect the friction packing belt. Therefore, cleaning components are set on both sides of the two augers to simultaneously remove impurities from their respective augers.

[0022] Furthermore, it also includes a detection component, which includes a wind-receiving plate and a push-button switch. The wind-receiving plate is disposed on the guide rail slider and located directly above the outlet end of the high-pressure nozzle. The wind-receiving plate is connected to a spring, and the free end of the spring is fixedly connected to the guide rail slider. The push-button switch is disposed on the back of the wind-receiving plate, and the wind-receiving plate is used to touch the push-button switch.

[0023] The principle and effect of this scheme are as follows: (1) When the friction strapping is loose and shifted, the friction strapping will tilt and drive on the auger. Therefore, this scheme uses the airflow from the high-pressure nozzle to detect whether the friction strapping is loose. When the high-pressure nozzle moves to the position of the friction strapping, the airflow from the high-pressure nozzle should be horizontal, that is, the gas will pass through the friction strapping, or only a small amount of airflow will flow back in reverse, which is insufficient to act on the air receiving plate to make it press the switch. When the friction strapping is loose and shifted, the airflow from the high-pressure nozzle will blow towards the tilted strapping due to the change in the position of the strapping, so that most of the gas will flow back in reverse to the air receiving plate. After the air receiving plate is subjected to force, it compresses the spring and presses the switch on its back, thereby detecting whether the friction strapping is shifted. (2) The airflow from the high-pressure nozzle of this scheme can clean the auger and detect whether the friction strapping is loose and shifted, and no additional detection device is required, so the structure is simple.

[0024] Furthermore, the guide rail slider is provided with a slide rail for guiding the wind-receiving plate, and the wind-receiving plate is slidably connected to the slide rail.

[0025] The principle and effect of this solution are as follows: the slide rail is used to provide positioning and guidance for the movement of the wind-receiving plate, preventing it from dislodging during the movement process.

[0026] Furthermore, the push switch is electrically connected to an alarm. The push switch is a normally open switch, and the alarm will sound when the push switch is pressed.

[0027] The principle and effect of this solution are as follows: When an alarm is set up, the internal contacts are connected when the switch is pressed, causing the alarm to sound and reminding the staff that the packing strap has shifted or loosened. Attached Figure Description

Detailed Implementation

[0036] The following will describe the concept and technical effects of this utility model clearly and completely with reference to the embodiments, so as to fully understand the purpose, features and effects of this utility model. Obviously, the described embodiments are only a part of the embodiments of this utility model, not all of them. Other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are all within the scope of protection of this utility model.

[0037] Example 1:

[0038] Please see Figure 1This embodiment provides a segmented integrated roller for residual film recycling combined operation, including a residual film auger 1, a cleaning component 2, a detection component 3, and a tensioning device 4. Two symmetrically arranged residual film augers 1 are provided, each with a friction packing strap 5 connected to its central portion for residual film collection. The residual film augers 1 have ordinary coarse threads and are located at the edge of the packing strap, completely replacing conventional drive rollers to rotate the packing strap, saving metal materials and further simplifying the structure. The residual film auger 1 is composed of multiple auger units 11, including a left-handed auger unit 111 and a right-handed auger unit 112. The left-handed and right-handed auger units 111 and 112 are symmetrically distributed along the central axis of the spiral main shaft 12, allowing debris to be discharged from both sides of the residual film auger 1 inside the packing strap. Each auger unit 11 includes a spiral spindle 12 and spiral auger plates 13 respectively disposed on the spiral spindle 12. Adjacent auger units 11 are connected by detachable connectors, which make the spiral spindles 12 of adjacent auger units 11 coaxially connected and make the spiral auger plates 13 of adjacent auger units form a continuous spiral structure after splicing. The connectors include a flat key 14, a stop ring 16 and a nut 17. The flat key 14 is embedded in the keyway 15 at the docking end of the central shaft of the adjacent auger. The stop ring 16 is fitted on the spiral spindle 12 and located at the docking gap of the adjacent auger units 11. The nut 17 is threaded to the end of the spiral spindle 12. By tightening the nut 17, the stop ring 16 is pressed against the docking end face of the adjacent auger units 11. By designing the auger for removing debris as a detachable structure composed of multiple auger units, and using a flat key 14, a stop ring 16, and a nut 17 to achieve coaxial connection of the spiral main shaft 12 of adjacent auger units 11 and continuous splicing of the spiral auger packing plate 13, when faced with packing film boxes of different models and sizes, different specifications and quantities of auger units 11 can be selected for combination and installation according to the internal space dimensions of the film box.

[0039] Please see Figure 4 and Figure 5 The tensioning device 4 includes a support plate 41, a bolt 42, and a movable plate 43. The support plate 41 is fixed to the inner wall of the membrane box, and the movable plate 43 is slidably connected to the support plate 41 via a dovetail groove. The end of the auger 1 is coaxially fixed to the support plate 41 via a bearing 44, and the inner ring of the bearing 44 is interference-fitted with the rotating shaft of the auger 1. When it is necessary to adjust the tension of the friction packing strap 5, the bolt 42 is rotated so that its end abuts against the movable plate 43. By adjusting the screw depth of the bolt 42, the movable plate 43 is pushed to slide along the support plate 41, thereby changing the axial position of the auger 1 and realizing the tensioning or relaxation of the friction packing strap 5.

[0040] Example 2:

[0041] The difference between this embodiment and the previous embodiment is as follows: Please refer to... Figures 2-7 Each auger 1 is equipped with a set of cleaning components 2 on its outer side to remove impurities adhering to the surface of the auger 1. The cleaning component 2 includes a high-pressure nozzle 21 and a drive unit. The drive unit includes a cylinder 22, an air pump 23, a cam 24, and a guide rail 25. The cylinder 22 is equipped with a return spring (not shown) for resetting the piston of the cylinder 22. One end of the return spring is fixedly connected to the piston, and the other end is fixedly connected to the cylinder body of the cylinder 22. A guide rail slider 251 is slidably arranged on the guide rail 25 along the length direction of the auger 1. The high-pressure nozzle 21 is arranged on the guide rail slider 251 to provide positioning and guidance for the high-pressure nozzle 21 to move on the guide rail. The outlet end of the high-pressure nozzle 21 faces the outer edge of the auger blade of the auger 1. The spray axis forms a perpendicular angle (preferably 80°-90°) with the axis of the auger 1. The high-pressure nozzle 21 is located below the transverse symmetrical axis of the auger 1, and the distance between it and the outer edge of the auger blade is 2-8cm, so that the high-pressure airflow can maintain an appropriate distance and avoid impurities being blown back into the nozzle due to excessive distance. Cam 24 is coaxially fixedly connected to the end of the auger 1. Air pump 23 is located inside the membrane box and is a push-type air pump 23. Air pump 23 is located below cam 24. Cam 24 is used to intermittently collide with air pump 23. The air outlet of air pump 23 is connected to the air inlet of cylinder 22 through a pipe. A pressure relief valve 26 is provided on guide rail 25. Pressure relief valve 26 is an electronic push-type pressure relief valve 26. This is an existing electronic push-type pressure relief valve 26. When pressure relief valve 26 is pressed, it automatically closes after a 15-second delay. Guide rail slider 251 is used to press pressure relief valve 26. One end of pressure relief valve 26 is connected to the air inlet of cylinder 22 through a pipe, and the other end is connected to high-pressure nozzle 21 through a pipe.

[0042] During operation, the auger 1 rotates, and the cam 24, which is coaxially fixed at its end, rotates synchronously with the auger 1, intermittently colliding with the air pump 23. When the air pump 23 is collided with, it generates gas, which is transported to the cylinder 22 through the pipeline. This pushes the piston rod of the cylinder 22, causing the guide rail slider 251 to move, thereby moving the high-pressure nozzle 21 along the guide rail 25. When the piston rod of the cylinder 22 extends to its limit position, it touches the pressure relief valve 26 through the guide rail slider 251, allowing the gas in the cylinder 22 to pass through the pipeline and the pressure relief valve 26, and finally be ejected from the high-pressure nozzle 21. At the same time as the gas is ejected, the piston rod slowly retracts under the action of the spring, thereby moving the high-pressure nozzle 21 and using the pressure relief valve 26 to release pressure on the cylinder 22, so that the gas cleans the auger 1, removing grass roots, wet soil and other impurities adhering to its surface, preventing impurities from clogging the spiral gap and avoiding long-term accumulation of impurities that affect the recovery of residual film.

[0043] The detection component 3 includes an air receiving plate 31, a push-button switch 32, and a spring 33. The air receiving plate 31 is slidably mounted on the guide rail slider 251 via a slide rail (not shown) and is located directly above the outlet end of the high-pressure nozzle 21. One end of the spring 33 is fixed to the guide rail slider 251, and the other end is connected to the back of the air receiving plate 31, so that the air receiving plate 31 maintains a distance from the push-button switch 32 in its natural state. When the friction packing strap 5 becomes loose and shifts, causing the airflow of the high-pressure nozzle 21 to be obstructed, the airflow reverses and impacts the air receiving plate 31, causing it to compress the spring 33 and trigger the normally open push-button switch 32 on the back. The push-button switch 32 is electrically connected to an alarm (such as a buzzer). After being triggered, the alarm emits a warning signal, prompting the operator to adjust the tensioning device 4 in time.

[0044] During equipment operation, the auger 1 rotates to convey impurities, while the high-pressure nozzle 21 reciprocates along the length of the auger, continuously flushing the surface of the auger blades with high-pressure airflow to remove adhering impurities. Each time the high-pressure nozzle 21 moves to the back area of ​​the friction strapping 5, it passes through the area of ​​the friction strapping 5 to detect whether the friction strapping 5 has shifted. When the high-pressure nozzle 21 moves to the position of the friction strapping 5, the airflow emitted by the high-pressure nozzle 21 should ideally be horizontal, such as... Figure 6 As shown, point A should be unobstructed, meaning that gas will pass through the friction strapping 5, or only a small amount of airflow will flow back, insufficient to act on the air receiving plate 31 to cause it to press the switch 32. When the friction strapping 5 becomes loose and shifts, the airflow from the high-pressure nozzle 21 will blow towards the tilted strapping due to the change in the position of the friction strapping 5 (e.g., ...). Figure 7 As shown in the diagram, most of the gas will flow back to the air receiving plate 31. Under pressure, the air receiving plate 31 compresses the spring 33 and abuts against the push-button switch 32 on its back, activating the alarm to prompt maintenance. The operator adjusts the position of the auger 1 using the tensioning device 4 to restore the friction strapping 5 to its correct tension, ensuring stable equipment operation.

It should be noted that those skilled in the art can make various modifications and improvements without departing from the structure of this utility model, and these should also be considered within the scope of protection of this utility model. These modifications will not affect the effectiveness of the implementation of this utility model or the practicality of the patent.
