Description

Technical Field

[0001] This utility model belongs to the technical field of field residual film collection and recycling equipment, specifically relating to a collection mechanism for a residual film recycling machine. Background Technology

[0002] Mulch film, also known as ground cover film, is usually transparent or green / silver. It is used to cover the ground to increase soil temperature, retain soil moisture, maintain soil structure, prevent pests from attacking crops and diseases caused by certain microorganisms, thereby promoting plant growth. Because mulch film is non-biodegradable, residual film must be collected and recycled after the crops mature to prevent environmental pollution and hinder the cultivation of the next season's crops.

[0003] For example, in the case of existing cotton crops, when cotton harvesting is completed and seasonal planting is needed, the straw in the field needs to be crushed and rotary tilled, and the existing residual film needs to be picked up and recycled in order to prepare the land. The existing residual film recycling machine is integrated with the tractor, straw machine and rotary tiller, and directly uses the power output of the tractor. The pickup part relies on the power output of the tractor to drive at a fixed speed. However, because the tractor's travel speed is unstable, the fixed speed transmission of the pickup does not match the travel speed, which will affect the pickup effect when picking up residual film.

[0004] Therefore, how to provide a picking mechanism for a residual film recycling machine with a high picking rate that adapts to the operating speed is a problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0005] In view of this, the present invention provides a picking mechanism for a residual film recycling machine, which can adapt to the walking speed of the traction equipment to ensure the picking effect of the picking mechanism.

[0006] To achieve the above objectives, this utility model adopts the following technical solution: a picking mechanism for a residual film recycling machine, comprising:

[0007] The ground roller has side frames rotatably connected to its two shaft ends, and the side frames can be detachably connected to the frame of the residual film recycling machine;

[0008] A pickup roller assembly, wherein the two shaft ends of the pickup roller assembly are respectively rotatably connected to the side frame on the corresponding side;

[0009] A bridge-drive gear set is rotatably connected to the side frame on either end of the floor roller. The bridge-drive gear set transmits power between the floor roller and the pickup roller assembly. The floor roller is the driving end, and the pickup roller assembly is the driven end, with the floor roller and the pickup roller assembly rotating in opposite directions.

[0010] The beneficial effects of this utility model are: the ground roller serves as the power source for the pickup roller assembly, ensuring that the rotational pickup speed of the pickup roller assembly matches the traveling speed of the traction equipment, thus preventing the problem of mismatch between the rotational speed of the pickup roller assembly and the traveling speed of the equipment. The bridge transmission gear set can output the rotational power of the ground roller to the pickup roller assembly, and the rotational direction of the pickup roller assembly is opposite to that of the ground roller, thereby ensuring the pickup effect.

[0011] Preferably, the outer wall of the ground roller is provided with spiral wolf teeth, and the ground roller rolls in the field and provides rotational power to the pickup roller assembly.

[0012] The resulting technical effect is that the spiral teeth ensure the rolling effect of the ground roller, prevent the ground roller from slipping and not rotating, and thus ensure the rotation and picking effect of the subsequent pickup roller assembly.

[0013] Preferably, the pickup roller assembly includes a central shaft, mounting plates, support rods, support plates, and spring claws. The two ends of the central shaft are rotatably connected to the side frames on the corresponding sides. There are two sets of mounting plates, which are fixed to the edges of both ends of the central shaft. There are multiple support rods, which are circumferentially spaced between the two mounting plates. The support plates are fixed on the central shaft and limit the deflection of the multiple support rods. There are multiple sets of spring claws, which are spaced apart and fixed on the support rods. The spring claws can hook out residual film in the field. The inner diameter of the roller is smaller than the inner diameter of the circle containing the support rods, and the edge linear velocity of the roller is smaller than the edge linear velocity of the circle containing the support rods.

[0014] The resulting technical effect is as follows: the pickup roller assembly consists of a central shaft, mounting plate, support rod, support plate, and spring claws. During pickup operation, the ground roller rotates counterclockwise, while the pickup roller assembly rotates clockwise. Since the size of the ground roller is smaller than the inner diameter of the circle containing the support rod, the spring claws on the pickup roller assembly have a forward displacement relative to the field to actively pick up residual film. It should also be noted that the pickup roller assembly of the pickup mechanism is not installed on the same horizontal line as the ground roller. The pickup roller assembly is installed higher than the ground roller to avoid the rotational influence caused by the compaction of the field.

[0015] Preferably, the support plate has multiple limiting slots spaced apart on its periphery, and the multiple support rods are respectively located in the multiple limiting slots.

[0016] The resulting technical effect is that, due to the long length of the support rod, it may bend during operation, which could affect the operation of the spring claw. The support plate ensures that the support rod does not deflect and also guarantees the installation stability of the support rod.

[0017] Preferably, the spring claw includes an integrally connected coil spring fixing section, a straight rod section, and a hook membrane section. The coil spring fixing section is fixedly connected to the support rod. The straight rod section is located between the coil spring fixing section and the hook membrane section and is arranged perpendicular to the axial direction of the support rod. The hook membrane section is fixed to the end of the straight rod section and is set to be deflected clockwise at a certain angle corresponding to the rotation direction of the mounting plate.

[0018] The resulting technical effect is that the coil spring fixing section serves as a stable foundation for the spring-loaded claw to be installed on the support rod. Specifically, the coil spring fixing section can be detachably fixed to the support rod using bolts. The support rod section and the film-hooking section work together to hook out the residual film in the field. Based on its elastic characteristics, the spring-loaded claw has a certain amount of working float, allowing it to enter the soil and hook out the residual film.

[0019] Preferably, the bridge transmission gear set includes an even number of meshing gear components. The shaft ends of the ground roller and the pickup roller assembly are both provided with meshing gears that mesh with the transmission gear components. The side frame on which the bridge transmission gear set is installed is provided with a surrounding plate, which, together with the side frame on the corresponding side, the transmission gear set and the meshing gears, forms a gearbox.

[0020] The resulting technical effect is that the bridge drive gear assembly realizes the reversal of the ground roller and the pickup roller assembly through an even number of gear components, and the gearbox structure can ensure the working environment of the gears and avoid premature gear damage.

[0021] Preferably, it also includes a stripping roller, which is located above the pickup roller assembly and rotatably connected to the frame. The power of the stripping roller comes from the power output shaft of the traction device. The stripping roller rotates in the opposite direction to the pickup roller assembly and removes residual film from the pickup roller assembly.

[0022] The resulting technical effect is that the stripping roller can remove the residual film hooked out by the pickup roller assembly, and the rotation of the stripping roller is independent of the rotation of the pickup roller assembly, thereby ensuring the stripping effect of the pickup roller assembly.

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] See appendix to this utility model Figures 1 to 4 According to an embodiment of the present invention, a picking mechanism for a residual film recycling machine includes:

[0030] The ground roller 1 has two shaft ends that are rotatably connected to the side frame 2, which can be detachably connected to the frame of the residual film recycling machine.

[0031] The pickup roller assembly 3 has two shaft ends that are rotatably connected to the corresponding side frame 2.

[0032] The bridge transmission gear set 4 is rotatably connected to the side frame 2 on either end of the ground roller. The bridge transmission gear set 4 transmits power between the shaft end of the ground roller 1 and the shaft end (central shaft) of the pickup roller assembly 3. The ground roller 1 is the driving end, and the pickup roller assembly 3 is the driven end, and the rotation directions of the ground roller 1 and the pickup roller assembly 3 are opposite.

[0033] It should be noted that the rotation center of the ground roller is lower than the rotation center of the pickup roller assembly. In other words, the installation position of the ground roller is lower than the installation position of the pickup roller assembly. During actual operation, the ground roller rolls in the field, and the main body (support rod) of the pickup roller assembly 3 does not compact the field. Instead, there is a certain gap on the ground surface, and the residual film in the field is picked up by the spring claw 35 on the pickup roller assembly 3.

[0034] In other embodiments, the outer side wall of the ground roller 1 is provided with spiral wolf teeth 11. The ground roller 1 rolls in the field and provides rotational power for the pickup roller assembly 3. The rolling of the ground roller is based on the travel speed of the equipment. That is, the rotation of the pickup roller assembly is based on the rotation of the ground roller. The rotation speed of the pickup roller assembly 3 is adaptively adjusted based on the travel speed of the equipment.

[0035] In other specific embodiments, the pickup roller assembly 3 includes a central shaft 31, mounting plates 32, support rods 33, support plates 34, and spring claws 35. The two ends of the central shaft 31 are rotatably connected to the side frames 2 on the corresponding sides. There are two sets of mounting plates 32, which are fixed to the edges of the two ends of the central shaft 31. There are multiple support rods 33, which are circumferentially spaced between the two mounting plates 32. The support plates 34 are fixed on the central shaft 31 and restrict the deflection of the multiple support rods 33. There are multiple sets of spring claws 35, which are spaced and fixed on the support rods 33. The spring claws 35 can hook out residual film in the field. The inner diameter of the ground roller 1 is smaller than the inner diameter of the circle where the support rods 33 are located. The edge linear velocity of the ground roller 1 is smaller than the edge linear velocity of the circle where the support rods 33 are located. The purpose is to ensure that the pickup roller assembly 3 actively picks up the film.

[0036] Understandably, when the ground roller is rolling normally, the edge linear velocity of the pickup roller assembly must be greater than the edge linear velocity of the ground roller. This is to ensure that the spring claws have a certain speed to actively hook out the residual film from the field.

[0037] In some other specific embodiments, the support plate 34 is provided with multiple limiting slots 341 at intervals on its periphery, and multiple support rods 33 are respectively located in multiple limiting slots 341, thereby ensuring the installability and axiality of the support rods and preventing deflection deformation that would affect the hooking effect of the spring claw.

[0038] In some other specific embodiments, the spring claw 35 includes an integrally connected coil spring fixing section 351, a straight rod section 352, and a film hooking section 353. The coil spring fixing section 351 is fixedly connected to the support rod 33. It should be noted that there is a ring plate on the end side of the coil spring fixing section 351, and bolt holes are opened on the ring plate. The support rod has fixing holes, and the connection between the coil spring fixing section 351 and the support rod 33 is achieved by bolts. The straight rod section 352 is located between the coil spring fixing section 351 and the film hooking section 353 and is arranged perpendicular to the axial direction of the support rod 33. The film hooking section 353 is fixed to the end of the straight rod section 352 and is set to bend clockwise at a certain angle corresponding to the rotation direction of the mounting plate 32, so that the film hooking section can extend into the field to hook out the residual film. Due to the curved design of the film hooking section 353 and the straight rod section 352, the hooked residual film can move upward, and then the external film removal roller can complete the process of removing and collecting the residual film.

[0039] In other embodiments, the bridge drive gear set 4 includes an even number of meshing gear components. The shaft ends of the ground roller 1 and the pickup roller assembly 3 are both provided with meshing gears of the meshing drive gear components. The side frame 2 on which the bridge drive gear set 4 is installed is provided with a surrounding plate and formed with a gearbox. The meshing gears and the bridge drive gear set rotate within the gearbox. The gearbox can provide a stable gear operating environment and extend the service life of the equipment.

[0040] In some other embodiments, a stripping roller 5 is also included. The stripping roller 5 is located above the pickup roller assembly 3 and is rotatably connected to the frame. The power of the stripping roller 5 comes from the power output shaft of the traction device. The stripping roller 5 rotates in the opposite direction to the pickup roller assembly 3 and removes residual film from the pickup roller assembly 3.

[0041] It should be noted that the rotational speed of the stripping roller is provided by an external power output, and its rotational speed must be greater than that of the pickup roller assembly to ensure that the residual film on the spring claws is removed.

[0042] The ground roller drives the pickup roller assembly of this device, which can change with the travel speed and adjust adaptively to ensure the pickup effect of the pickup mechanism.

[0043] The apparatus and methods disclosed in the embodiments are described simply because they correspond to the methods disclosed in the embodiments. For relevant details, please refer to the method section.

[0044] The above description of the disclosed embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention.
