Description

Technical Field

[0001] This utility model relates to the field of agricultural machinery technology, specifically to a picking device for an anti-tangling farmland residual film recycling machine. Background Technology

[0002] In agricultural production, plastic film mulching technology is widely used in various crop cultivation fields because it can increase soil temperature, maintain soil moisture, and reduce weed growth. However, if plastic film is not recycled in a timely and thorough manner after use, it will remain in the soil for a long time, damaging soil structure, hindering crop root development, and even causing soil pollution. Therefore, the recycling of residual plastic film in farmland has become a key link in the green development of agriculture.

[0003] In the prior art, for example, Chinese Patent Publication No. CN218456669U discloses a picking mechanism for a roller-type residual film recycling machine, belonging to the field of agricultural machinery technology. This utility model includes: a drive wheel, which is mounted on the frame of the roller-type residual film recycling machine and rests on the ground during operation; a traction arm, whose two ends are rotatably connected to the picking roller assembly and the two sides of the drive wheel of the roller-type residual film recycling machine; and a transmission mechanism, which is connected to the picking roller assembly and the drive wheel respectively, and is used to transmit the driving force generated by the drive wheel to the picking roller assembly, so that the linear velocity of the picking roller assembly matches the forward speed of the roller-type residual film recycling machine. The picking mechanism of the roller-type residual film recycling machine provided by this invention has its rotational speed driven according to the forward speed of the roller-type residual film recycling machine, ensuring that the linear velocity of the picking roller assembly and the forward speed of the roller-type residual film recycling machine are maintained at the designed ratio, thus ensuring the operational quality of the residual film recycling machine.

[0004] While the above-mentioned technical solutions have the aforementioned advantages, their disadvantages are as follows: During the rewinding process of residual film, soil particles, crop straw, and other impurities attached to the surface of the residual film may enter the pickup roller assembly along with the residual film. These impurities are easily stuck in the gaps between the rollers or wrapped around the surface of the roller shaft, requiring manual cleaning of the wrapped material, which seriously affects the efficiency of the operation. Furthermore, as the thickness of the residual film roll increases, the residual film is prone to loose wrinkles, and the wrinkled areas are prone to entanglement with adjacent components, further aggravating the risk of entanglement. It is impossible to prevent entanglement from occurring throughout the entire process of conveying and winding, resulting in extremely poor anti-entanglement effect. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a picking device for an anti-tangling farmland residual film recycling machine, which solves the problem of residual film easily tangling during winding.

[0006] To achieve the above objectives, this utility model is implemented through the following technical solution: a picking device for an anti-tangling farmland residual film recycling machine, including a movable frame, a guide roller rotatably connected to the outer side of the movable frame, an mounting frame fixedly connected to the side of the movable frame near the guide roller, a cleaning brush fixedly connected to the inner side of the mounting frame, and further including: a fixing component, the fixing component being fixedly installed on the inner side of the movable frame, the bristles of the cleaning brush continuously sweeping away soil, straw and other impurities adhering to the surface of the residual film, the guide roller adopting a conical structure with a small diameter in the middle and gradually increasing towards both sides, which can generate a guiding force that converges towards the middle when the residual film is conveyed, avoiding the residual film from spreading to both sides due to conveying deviation, and reducing the risk of tangling caused by the edge of the residual film hooking onto the mounting frame;

[0007] The fixing assembly includes a fixing frame, a sliding seat slidably connected to the inner side of the fixing frame, a compression spring fixedly connected to the bottom of the sliding seat, a pressure roller rotatably connected to the outer side of the sliding seat, a bearing snapped into the top of the fixing frame, and a limit block rotatably connected to the outer side of the fixing frame. The pressure roller drives the winding roller to rotate synchronously inside the bearing through friction, realizing continuous winding and collection of residual film. As the thickness of the residual film on the winding roller increases, the residual film roll will push the pressure roller to move downward, causing the sliding seat to squeeze the compression spring. The spring force adaptively adjusts the clamping force to ensure that the pressure roller is always in close contact with the surface of the residual film roll.

[0008] Preferably, the bottom of the fixed frame is fixedly connected to the inner side of the movable frame, and the bottom end of the compression spring is fixedly connected to the inner side of the fixed frame. Under the elastic force of the compression spring, the sliding seat can always maintain an upward movement trend.

[0009] Preferably, a locking block is slidably connected to the inner side of the fixing frame, and a return spring is fixedly connected to the inner side of the locking block. The end of the return spring away from the locking block is fixedly connected to the inner side of the fixing frame. A sliding rod is slidably connected to the inner wall of the fixing frame. When the locking block is located inside the fixing frame, the return spring is compressed by force.

[0010] Preferably, one end of the slide rod is fixedly connected to the inner side of the locking block, and the other end of the slide rod is fixedly connected to a handle. The outer wall of the slide rod is slidably connected to the inner wall of the movable frame. By pulling the handle, the slide rod is moved outward, and the slide rod pulls the locking block into the inner side of the fixed frame.

[0011] Preferably, the outer side of the locking block is inserted into the inner wall of the limiting block through a groove, and the groove is formed in the wall of the limiting block. The reset spring can push the locking block to reset and insert it into the groove on the limiting block to lock the limiting block.

[0012] The beneficial effects of this utility model are as follows:

[0013] (i) The device quickly completes the installation of the winding roller by setting a fixed component, and at the same time sets a compression spring to keep the sliding seat always moving upward, so that the pressure roller presses tightly against the surface of the residual film on the winding roller; the pressure roller drives the winding roller to rotate synchronously inside the bearing through friction, so as to realize the continuous winding and collection of residual film. As the thickness of the residual film on the winding roller increases, the residual film roll will push the pressure roller to move downward, causing the sliding seat to squeeze the compression spring. The spring force adaptively adjusts the clamping force to ensure that the pressure roller is always in close contact with the surface of the residual film roll, ensuring the winding tightness, thereby reducing the risk of entanglement.

[0014] (ii) The device uses a cleaning brush to continuously sweep away soil, straw, and other impurities adhering to the surface of the residual film. After cleaning, the residual film bypasses the guide roller and is finally fixed at the starting end of the winding roller. The guide roller adopts a conical structure with a small diameter in the middle and gradually increasing in size towards both sides. During the conveying of the residual film, it can generate a guiding force that converges towards the center, preventing the residual film from spreading to both sides due to conveying deviation and reducing the risk of entanglement caused by the edge of the residual film catching on the mounting frame.

[0020] 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.

[0021] Example: Please refer to Figure 1-4This utility model provides a technical solution: a picking device for an anti-tangling agricultural film residue recycling machine, including a movable frame 1, a guide roller 2 rotatably connected to the outer side of the movable frame 1, an mounting frame 4 fixedly connected to the side of the movable frame 1 near the guide roller 2, and a cleaning brush 5 fixedly connected to the inner side of the mounting frame 4. It also includes a fixing component 3, which is fixedly installed on the inner side of the movable frame 1. One end of the residual film to be recycled passes through the gap between the cleaning brushes 5 on the mounting frame 4. During the film winding process, the bristles of the cleaning brush 5 continuously clean the soil, straw, and other impurities adhering to the surface of the residual film. After cleaning, the residual film bypasses the guide roller 2 and is finally fixed at the starting end of the winding roller. The guide roller 2 adopts a conical structure with a small diameter in the middle and gradually increasing diameter towards both sides. During the conveying of the residual film, it can generate a guiding force that converges towards the center, preventing the residual film from spreading to both sides due to conveying deviation and reducing the risk of tangling caused by the edge of the residual film hooking onto the mounting frame 4.

[0022] The fixing assembly 3 includes a fixing frame 31, a sliding seat 32 slidably connected to the inner side of the fixing frame 31, a compression spring 33 fixedly connected to the bottom of the sliding seat 32, a pressure roller 34 rotatably connected to the outer side of the sliding seat 32, a bearing 35 snapped into the top of the fixing frame 31, a limit block 36 rotatably connected to the outer side of the fixing frame 31, a bottom of the fixing frame 31 fixedly connected to the inner side of the movable frame 1, and a bottom end of the compression spring 33 fixedly connected to the inner side of the fixing frame 31. A motor mounted on the sliding seat 32 drives the pressure roller 34 to rotate actively, pressing... Under the elastic force of the compression spring 33, the sliding seat 32 always maintains an upward movement trend, so that the pressure roller 34 is pressed tightly against the surface of the residual film on the winding roller. The pressure roller 34 drives the winding roller to rotate synchronously inside the bearing 35 through friction, so as to realize the continuous winding and collection of residual film. As the thickness of the residual film on the winding roller increases, the residual film roll will push the pressure roller 34 to move downward, causing the sliding seat 32 to squeeze the compression spring 33. The spring force adaptively adjusts the clamping force to ensure that the pressure roller 34 is always in close contact with the surface of the residual film roll, thus ensuring the winding tightness.

[0023] A locking block 38 is slidably connected to the inner side of the fixed frame 31. A return spring 311 is fixedly connected to the inner side of the locking block 38. The end of the return spring 311 away from the locking block 38 is fixedly connected to the inner side of the fixed frame 31. A sliding rod 39 is slidably connected to the inner wall of the fixed frame 31. One end of the sliding rod 39 is fixedly connected to the inner side of the locking block 38, and the other end of the sliding rod 39 is fixedly connected to a handle 310. The outer wall of the sliding rod 39 is slidably connected to the inner wall of the movable frame 1. The outer side of the locking block 38 is inserted into the inner wall of the limiting block 36 through a groove 37, and the groove 37 is opened in the wall of the limiting block 36. When installing the winding roller, first... The bearing 35 is fitted onto both sides of the winding roller, and then the bearing 35 is snapped into the top slot of the fixing frame 31. By pulling the handle 310, the slide bar 39 is moved outward, and the slide bar 39 pulls the locking block 38 into the inner side of the fixing frame 31. At this time, the return spring 311 is compressed. The limiting block 36 is flipped downward so that it fits against the outer side of the bearing 35. After releasing the handle 310, the return spring 311 pushes the locking block 38 to reset and insert it into the groove 37 on the limiting block 36, thereby locking the limiting block 36. This, together with the fixing frame 31, completes the axial fixation of the bearing 35 and the winding roller, and quickly completes the installation of the winding roller.

[0024] Working principle: During use, the mobile frame 1, acting as the overall load-bearing structure, is connected to an external traction device, moving the entire device directly above the area of ​​residual plastic film in the farmland. Before operation, the winding roller must be installed using the fixing component 3.

[0025] When installing the winding roller, first, place the bearing 35 on both sides of the winding roller, and then insert the bearing 35 into the top slot of the fixing frame 31. By pulling the handle 310, the slide bar 39 is moved outward, and the slide bar 39 pulls the locking block 38 into the inner side of the fixing frame 31. At this time, the return spring 311 is compressed. Flip the limiting block 36 downward so that it fits against the outside of the bearing 35. After releasing the handle 310, the return spring 311 pushes the locking block 38 to reset and insert it into the groove 37 on the limiting block 36, thereby locking the limiting block 36. This, together with the fixing frame 31, completes the axial fixation of the bearing 35 and the winding roller, and quickly completes the installation of the winding roller. Then, one end of the residual film to be recycled is passed through the gap between the cleaning brushes 5 on the mounting frame 4. During the winding process of the residual film, the bristles of the cleaning brushes 5 will continuously clean the soil, straw and other impurities attached to the surface of the residual film. After cleaning, the residual film passes around the guide roller 2 and is finally fixed at the starting end of the winding roller. The guide roller 2 adopts a conical structure with a small diameter in the middle and gradually increasing diameter towards both sides. When the residual film is conveyed, it can generate a guiding force that converges towards the middle, preventing the residual film from spreading to both sides due to conveying deviation and reducing the risk of entanglement caused by the edge of the residual film getting caught on the mounting frame 4.

[0026] During operation, the motor installed on the sliding seat 32 drives the pressure roller 34 to rotate actively. Under the elastic force of the compression spring 33, the sliding seat 32 always maintains an upward movement trend, so that the pressure roller 34 presses tightly against the surface of the residual film on the winding roller. The pressure roller 34 drives the winding roller to rotate synchronously inside the bearing 35 through friction, so as to realize the continuous winding and collection of residual film. As the thickness of the residual film on the winding roller increases, the residual film roll will push the pressure roller 34 to move downward, causing the sliding seat 32 to squeeze the compression spring 33. The spring force adaptively adjusts the clamping force to ensure that the pressure roller 34 is always in close contact with the surface of the residual film roll, thus ensuring the winding tightness.

[0027] Once the winding roller is fully loaded with residual film, pull the handle 310 to disengage the locking block 38 from the groove 37, and flip the limiting block 36 upward to release the winding roller from its fixation. Remove the winding roller to unload the residual film. After replacing with a new winding roller, repeat the above installation steps to continue the operation.
