Description

Technical Field

[0001] This utility model relates to the technical field of crushing and returning devices to the field, and in particular to a crushing and returning device for sweet potato vines to the field. Background Technology

[0002] In the large-scale cultivation of sweet potatoes, the post-harvest treatment of vines is a crucial link affecting both planting efficiency and environmental protection. Traditional methods, such as burning vines, produce harmful gases that pollute the air, and indiscriminate disposal easily breeds pests. Silage processing requires additional investment in transportation and storage equipment, resulting in high costs and making it unsuitable for the high-efficiency operations required by small and medium-sized growers and large-scale planting bases. Against this backdrop, the sweet potato vine crushing and returning-to-the-field device has emerged, offering advantages such as on-site crushing and nutrient return to the soil. It not only transforms vines into natural organic fertilizer, improving soil fertility, but also significantly reduces labor costs, aligning with the modern agricultural development concept of green and efficient farming. It has become an important piece of equipment in agricultural machinery operations in major sweet potato producing areas.

[0003] The existing sweet potato vine crushing and returning device mainly consists of core components such as a power input mechanism, a feeding and conveying mechanism, a crushing and cutting mechanism, a spreading mechanism, and a frame. In actual operation, a tractor serves as the power source, transmitting power to the device's input shaft via a universal joint drive shaft. The input shaft then drives the feeding rollers through a transmission component, evenly conveying the sweet potato vines collected from the field into the crushing chamber. Inside the crushing chamber, high-speed rotating blades and fixed blades work together to cut and crush the vines into short segments through shearing and impact. The crushed vine segments are accelerated by a spreading impeller under centrifugal force and finally evenly scattered onto the farmland surface through an adjustable spreading cylinder, completing the crushing and returning process.

[0004] Existing sweet potato vine crushing and returning devices, during long-term continuous operation, are prone to gradual loosening of the transmission belt due to frequent stress and stretching, frictional heating and aging, and material fatigue. Furthermore, existing equipment generally lacks a convenient and efficient tension adjustment structure. When the transmission belt loosens, the power transmission efficiency decreases significantly, and slippage may even occur. This leads to unstable blade speed and insufficient cutting force in the crushing and cutting mechanism, resulting not only in incomplete crushing of the sweet potato vines and uneven fragment lengths, but also increased cutting resistance further exacerbates transmission belt wear, severely affecting the equipment's operational quality and continuous operating efficiency. Therefore, a new sweet potato vine crushing and returning device is proposed to address these problems. Summary of the Invention

[0005] In order to solve the above-mentioned technical problems, this utility model provides a sweet potato vine crushing and returning device, which aims to improve the problem of reduced transmission efficiency or slippage caused by the loosening of the transmission belt due to long-term use.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A sweet potato vine crushing and returning device includes a vine-killing machine.

Detailed Implementation

[0024] 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.

[0025] Reference Figures 1-4This utility model discloses a sweet potato vine crushing and returning device, including a vine-killing machine 1. The vine-killing machine 1 is driven by a power device to operate the working parts, and uses cutting, crushing or crushing methods to physically process the sweet potato vines, cutting, crushing or crushing them, making them easier to return to the field for decomposition or cleaning, thereby completing the removal of sweet potato vines in the field after crop harvest. This is prior art, so it will not be described in detail. The top of the vine-killing machine 1 is fixedly connected to a YJ-500 motor 2, which serves as the core power source. This motor 2 is used to provide stable power output for the rotation of the blade connecting shaft 6. The output end of the motor 2 is fixedly connected to... A pulley 4, in conjunction with a motor 2, rotates synchronously, achieving the initial transmission of power. A blade connecting shaft 6 is rotatably connected to the inner wall of the vine-killing machine 1 via a deep-groove ball bearing. This blade connecting shaft 6 is used to mount blades and rotate at high speed, effectively cutting and returning the sweet potato vines to the field. A pulley 5 is fixedly connected to one end of the blade connecting shaft 6. A transmission belt 7 made of high-wear-resistant rubber is installed between pulley 4 and pulley 5, connecting the two pulleys and precisely transmitting the power of the motor 2 to the blade connecting shaft 6, ensuring the continuity of the cutting operation. A lifting mechanism is located on one side of the vine-killing machine 1. The protective shell 3 serves a safety function, shielding the high-speed rotating transmission belt 7 to prevent accidents and ensure operator safety. The outer wall of the transmission belt 7 is equipped with an adjustment component to adjust its surface tension according to wear and usage, preventing reduced transmission efficiency or slippage due to belt slack. The top of the seedling cutter 1 is equipped with a dust removal component, which sprays water mist to settle dust generated during the cutting process, aiming to purify the working environment and protect the respiratory health of workers. The adjustment component includes a roller 8 made of nylon, which is connected to the transmission belt. The outer walls of the 7 are fitted together, and the tension of the transmission belt 7 is changed by applying pressure. The outer wall of the roller 8 is rotatably connected to the connecting frame 9. The connecting frame 9 is fixedly connected to the rotating shaft 10 by welding. The connecting frame 9 swings at a certain angle with the rotating shaft 10, thereby driving the roller 8 to move. One end of the rotating shaft 10 is rotatably connected to the inside of the seedling killer 1. The outer wall of the rotating shaft 10 is provided with a sliding groove 11. The sliding groove 11 is used to provide a linear sliding guide track for the square slider 12, ensuring that the sleeve 13 will not cause the rotating shaft 10 to deflect at an angle when rotating. One end of the rotating shaft 10 is provided with a rotating component.The rotating assembly includes a precision threaded rod 14 made of 45# steel. The threaded rod 14 is located at one end of the rotating shaft 10. A fixing frame 30 is fixedly connected to one side of the protective shell 3. The threaded rod 14 is threaded into the inside of the fixing frame 30. By rotating the handle 15, it can be screwed in or out of the fixing frame 30, thus converting rotational motion into linear motion. A sleeve 13 is fixedly connected to one end of the threaded rod 14. The sleeve 13 is used to move along the axial direction of the rotating shaft 10 under the drive of the threaded rod 14, thereby changing the position of the roller 8. A square slider 12 is fixedly connected to the inner wall of the sleeve 13. The square slider 12 is slidably connected to the inner wall of the groove 11. The square slider 12 cooperates with the groove 11 to achieve stable linear sliding, achieving the purpose of constraining the sleeve 13 while transmitting thrust, preventing it from rotating with the threaded rod 14. A handle 15 is fixedly connected to the other end of the threaded rod 14 for easy manual operation. The handle 15 allows the operator to easily and effortlessly rotate the threaded rod 14, achieving precise control of tension adjustment.

[0026] Reference Figure 1 and Figure 5 The dust removal assembly includes a stainless steel spray pipe 20, located at the top of the seedling killer 1. The spray pipe 20 has evenly distributed nozzles on its surface for atomizing pressurized water and spraying it over a wide area to effectively suppress dust. A fixed frame 23 and a fixed block 28 are fixedly connected to the top of the seedling killer 1. A 370W micro motor 29 is fixedly connected to one side of the fixed block 28. A transmission plate 27 is fixedly connected to the output end of the motor 29. A connecting block 25 is rotatably connected to one side of the transmission plate 27. This connecting block 25 works in conjunction with the transmission plate 27 to achieve stable circular motion, providing continuous driving force for the oscillation of the spray pipe 20. A rotating bar 22 is fixedly connected to the inner wall of the fixed frame 23. A connecting plate 21 is fixedly connected to the outer wall of the rotating bar 22. One side of the connecting plate 21 is fixedly connected to the outer wall of the spray pipe 20. A connecting plate 24 is fixedly connected to one side of the connecting plate 21. The connecting plate 24 has an arc-shaped groove inside to constrain the sliding bar 26. The motion trajectory is as follows: both sides of the connecting block 25 are fixedly connected to the sliding strips 26. The sliding strips 26 are slidably connected to the inner wall of the groove of the connecting plate 24. The sliding strips 26, in conjunction with the revolution force of the connecting block 25, slide in the arc groove of the connecting plate 24, realizing the clever transmission of the rotational motion into the reciprocating oscillating force. Finally, the connecting plate 21 is driven to oscillate back and forth with the rotating strip 22 as the fulcrum, so that the spray pipe 20 can spray comprehensively. The other side of the seedling killer 1 is fixedly connected to the fixing plate 16. The top of the fixing plate 16 is fixedly connected to the large-capacity PE material water tank 17 and the water pump 18. The water tank 17 is used to store the water source required for dust suppression, and the water pump 18 is used to provide pressure to the water supply pipeline to ensure that the nozzle can spray a sufficiently fine water mist. The output end of the water tank 17 and the input end of the water pump 18 are connected through a pipe. The output end of the water pump 18 is fixedly connected to the high-pressure resistant delivery hose 19. One end of the delivery hose 19 is connected to the spray pipe 20.

[0027] The working principle of this utility model is as follows: During the use of the equipment, the vehicle tows the vine-killing machine 1 to move in the field, and at the same time, the motor 2 is started. The output end of the motor 2 drives the pulley 4 to rotate, and through the transmission belt 7, it drives the pulley 5 and the blade connecting shaft 6 to rotate. The blades on the surface of the blade connecting shaft 6 cut the sweet potato vines and return them to the field. When it is necessary to adjust the surface tension of the transmission belt 7, the handle 15 is rotated, causing the threaded rod 14 to rotate inside the fixed frame 30, and driving the sleeve 13 to rotate and move on the outer wall of the rotating shaft 10. While the sleeve 13 is rotating, it will drive the roller 8 to rotate around the rotating shaft 10, applying different degrees of pressure to the surface of the transmission belt 7, thereby adjusting the surface tension of the transmission belt 7. The moving force of the sleeve 13 will drive the square slider 12 to move on the surface of the rotating shaft 10. The sliding of the inner wall of the groove 11 does not affect the angle of the rotating shaft 10. While the vine-killing machine 1 is running, the water pump 18 will also transport the water in the water tank 17 to the nozzle 20 at one end of the conveying hose 19, and spray it out through the nozzle on one side of the nozzle 20. Then the motor 29 is started, and the output end of the motor 29 drives the transmission plate 27 to rotate, so that the connecting block 25 rotates around the output end of the motor 29. During this process, the slide bar 26 will slide on the surface of the arc groove inside the connecting plate 24. The revolution force of the connecting block 25 will drive the connecting plate 21 on one side of the connecting plate 24 to swing within a certain range around the rotating bar 22, so that the spraying range of the nozzle 20 is more comprehensive, and the dust generated by the cutting of sweet potato vines is reduced to prevent the dust from being inhaled by the surrounding workers.
