Description

Technical Field

[0001] This invention relates to the field of agricultural machinery technology, and in particular to a self-cleaning soil turning device for a tracked rotary tiller. Background Technology

[0002] A tracked rotary tiller is a type of agricultural machinery. Tracked rotary tillers typically consist of one or more pairs of rubber tracks, replacing the traditional tire design. The track design provides better traction and maneuverability in various terrains and soil conditions, especially on wet or uneven ground. Tracked rotary tillers are characterized by strong traction, stability and smoothness, minimal soil compaction and rolling, and high adaptability. They are mainly used for deep tillage and land preparation, effectively loosening, turning, and mixing the soil to create more ideal soil conditions for crop growth. Tracked rotary tillers are commonly used in large fields or situations requiring frequent terrain changes, such as orchards and vineyards. Overall, tracked rotary tillers, with their superior traction, stability, and adaptability, provide an important tool in modern agricultural production, effectively improving soil quality and increasing crop yields.

[0003] In existing technologies, soil needs to be turned over during crop planting to loosen it for better planting. However, when using a typical tracked rotary tiller, the tilling claws on the tiller cannot loosen the soil and remove the soil adhering to them at the same time. If the soil is relatively moist, the soil will adhere to the tilling claws, filling the gaps between the claws and increasing the resistance during tilling. This increases the burden on the tilling claws, and prolonged use can easily cause them to bend and break. Therefore, we propose a self-cleaning tilling device for tracked rotary tillers to solve the above problems. Summary of the Invention

[0004] The purpose of this application is to provide a self-cleaning soil-turning device for a tracked rotary tiller, in order to solve the problem mentioned in the background art that when a conventional tracked rotary tiller is used for planting and turning soil, the turning claws on the rotary tiller are difficult to loosen the soil and remove the soil adhering to the turning claws at the same time. If the soil is relatively moist, the soil will adhere to the turning claws, which will fill the gaps on or between the turning claws with soil, increasing the resistance when turning the soil, increasing the burden on the turning claws, and making the turning claws prone to bending and damage after long-term use.

[0005] To achieve the above objectives, this application provides the following technical solution: a self-cleaning soil-turning device for a tracked rotary tiller, comprising: A track drive unit and a transmission rod, wherein the right end of the transmission rod is mounted on the track drive unit; A docking block, which is fixedly installed on the left end of the transmission rod; Mounting plate, which is fixedly installed on the bottom of the docking block; The side plates are configured as two, with the top ends of the two side plates respectively fixedly installed on the left and right sides of the mounting plate; The housing is fixedly installed on the bottom of the mounting plate; An adjustment box, which is slidably connected to the bottom of the box body; A rotary tillage assembly includes: two support rods, a rotary shaft, multiple turning claws, a first motor, and two drive wheels. The top ends of the two support rods are fixedly connected to the bottom of the mounting plate. The front and rear ends of the rotary shaft pass through the two support rods and are rotatably connected to them. The multiple turning claws are fixedly mounted on the rotary shaft. The first motor is fixedly mounted on the front side of the front support rod. The two drive wheels are fixedly mounted on the output shaft of the first motor and the front end of the rotary shaft, respectively. The same drive belt is fitted on the two drive wheels. The cleaning assembly includes: a high-pressure nozzle, a first connector, a water tank, a high-pressure water pump, and a second connector. The high-pressure nozzle is located below the regulating box. The first connector is fixedly connected to the high-pressure nozzle. The water tank is fixedly installed on the top of the mounting plate. A filling port is provided on the top of the water tank. The high-pressure water pump is fixedly connected to the front side of the water tank. The second connector is fixedly connected to the front side of the high-pressure water pump. The first connector and the second connector cooperate with each other. Here, the first connector and the second connector are connected through a corrugated expansion tube to realize the water supply operation. A transmission assembly is disposed inside the housing and cooperates with the regulating housing; An adjustment component is disposed inside the adjustment box and cooperates with the high-pressure nozzle; A dustproof component is installed at the bottom of the housing and works in conjunction with the regulating box; A soil scraping assembly is mounted on the right-side side plate and engages with a soil-turning claw.

[0006] With the above structure, starting the first motor drives the upper transmission wheel to rotate. Then, through the transmission cooperation between the two transmission wheels and the transmission belt, the rotary tiller shaft can be driven to rotate. When the rotary tiller shaft rotates, it drives multiple turning claws to rotate. At this time, the turning claws can perform rotary tillage and turning operations on the soil. In addition, starting the high-pressure water pump can draw water from the water tank and transport it through the first connector, the corrugated telescopic pipe and the second connector. Then, water is sprayed through the high-pressure nozzle. In this way, the soil on the rotary tiller shaft and multiple turning claws can be washed away, thereby preventing soil from covering the rotary tiller shaft and multiple turning claws, reducing the running resistance of multiple turning claws, and preventing the multiple turning claws from being damaged due to excessive resistance caused by soil.

[0007] Preferably, a protective cover is fixedly installed on the front side of the support rod located at the front. The first motor, two transmission wheels and transmission belt are all located inside the protective cover. A breathable dustproof net can be installed on the protective cover for heat dissipation of the first motor.

[0008] Furthermore, by setting up a protective cover, the first motor, the two drive wheels, and the drive belt can be protected from dust, preventing dirt and dust from contaminating the first motor, the two drive wheels, and the drive belt, and ensuring stable transmission between the first motor, the two drive wheels, and the drive belt.

[0009] Preferably, the left side of the water tank is provided with an observation window and a scale line, and the scale line cooperates with the observation window.

[0010] Furthermore, by setting up observation windows and scale lines, it is easy for personnel to check the water level inside the water tank and to add water to the tank in a timely manner.

[0011] Preferably, the transmission assembly includes a second motor, a lead screw, a nut, and a slider. The second motor is fixedly installed on the front side of the housing. The front end of the lead screw is fixedly installed on the output shaft of the second motor. The rear end of the lead screw is rotatably connected to the inner wall of the rear side of the housing. The nut is threaded onto the lead screw. The slider is fixedly installed at the bottom of the nut. The bottom end of the slider penetrates the bottom inner wall of the housing and extends to the outside of the housing. The bottom end of the slider is fixedly installed at the top of the adjustment box.

[0012] Furthermore, starting the second motor can drive the lead screw to rotate. When the lead screw rotates, it can drive the nut to move laterally. When the nut moves laterally, it can drive the slider, the adjusting box and the high-pressure nozzle to move laterally. When the high-pressure nozzle moves laterally, it can facilitate the high-pressure nozzle to thoroughly flush and clean the entire rotary tiller shaft and multiple tilling claws, improving the cleaning efficiency and effect of the rotary tiller shaft and multiple tilling claws.

[0013] Preferably, a first sliding hole is provided on the bottom inner wall of the box body, and the bottom end of the slider passes through the first sliding hole and is slidably connected to the inner wall of the first sliding hole.

[0014] Furthermore, by opening the first sliding hole, the slider can be stably limited and supported, while also facilitating transmission between the nut and the adjusting box.

[0015] Preferably, the adjustment assembly includes a third motor, a half-tooth gear, a rotating shaft, a drive gear, a torsion spring, and a swing rod. The third motor is fixedly installed on the inner front wall of the adjustment box. The half-tooth gear is fixedly sleeved on the output shaft of the third motor. The rotating shaft is rotatably connected to the inner wall of the adjustment box. The drive gear is fixedly sleeved on the rotating shaft and meshes with the half-tooth gear. The torsion spring is sleeved on the rotating shaft. The rear end of the torsion spring is fixedly connected to the front side of the drive gear, and the front end of the torsion spring is fixedly connected to the inner front wall of the adjustment box. A second sliding hole is provided on the inner bottom wall of the adjustment box. The top end of the swing rod passes through the second sliding hole and is fixedly connected to the drive gear. The bottom end of the swing rod is fixedly connected to the top end of the high-pressure nozzle.

[0016] Furthermore, starting the third motor drives the semi-tooth gear to rotate. Through the meshing transmission between the semi-tooth gear and the drive gear, the drive gear rotates counter-clockwise. When the drive gear rotates counter-clockwise, it drives the rotating shaft to rotate counter-clockwise, and the torsion spring is twisted. When the drive gear aligns with the plane on the semi-tooth gear, the drive gear disengages from the semi-tooth gear. Then, through the elastic reset characteristic of the torsion spring, the rotating shaft and drive gear rotate and reset. Through the continuous rotation of the semi-tooth gear and the cooperation between the torsion spring, the rotating shaft and drive gear can reciprocate in both directions. When the drive gear reciprocates in both directions, it drives the swing arm and high-pressure nozzle to reciprocate in both directions. When the high-pressure nozzle reciprocates in both directions, it increases the spray range of the high-pressure nozzle, thereby ensuring the complete cleaning of the rotary tiller shaft and multiple tilling claws, and improving the cleaning effect.

[0017] Preferably, an arc-shaped dustproof plate is fixedly sleeved on the swing rod, the arc-shaped dustproof plate is slidably connected to the bottom of the adjustment box, and the arc-shaped dustproof plate cooperates with the second sliding hole.

[0018] Furthermore, by setting an arc-shaped dustproof plate, the second sliding hole can be sealed when the swing arm swings back and forth, preventing dust and dirt from entering the adjustment box and ensuring the stable drive of the adjustment component.

[0019] Preferably, the dustproof assembly includes four first hydraulic rods and two dustproof baffles. The four first hydraulic rods are fixedly installed on the outside of the housing in a rectangular array. The two dustproof baffles are slidably connected to the bottom of the housing. The output shafts of the first hydraulic rods are fixedly installed on the corresponding dustproof baffles. The two dustproof baffles are provided with adapter grooves on the side that is close to each other. Both adapter grooves are matched with the adjustment box.

[0020] Furthermore, by activating the four first hydraulic rods, the two dust baffles can be moved closer or further apart, thereby blocking the first sliding hole when the rotary tiller and multiple tilling claws are tilling the soil. The two adapter slots can also engage with the regulating box to achieve a perfect fit, preventing dust and soil from entering the box and ensuring the stable operation of the transmission components. At the same time, when using the high-pressure nozzle, opening the two dust baffles and releasing the obstruction limit on the regulating box and the high-pressure nozzle will not affect the normal lateral movement of the regulating box and the high-pressure nozzle.

[0021] Preferably, the soil scraping assembly includes a second hydraulic rod, a movable plate, and multiple cleaning blocks. The second hydraulic rod is fixedly installed on the right side of the right side plate. The output shaft of the second hydraulic rod passes through the right side plate and is slidably connected to it. The output shaft of the second hydraulic rod is fixedly installed on the right side of the movable plate. The right ends of the multiple cleaning blocks are all fixedly installed on the left side of the movable plate. The cleaning blocks cooperate with the corresponding soil turning claws.

[0022] Furthermore, by activating the second hydraulic rod, the moving plate can be moved. When the moving plate moves, it can move multiple cleaning blocks. At this time, the corresponding turning claws can be inserted into two adjacent cleaning blocks, and then drive the rotary tiller and multiple turning claws to rotate. The cleaning blocks can scrape away the soil from the rotary tiller and multiple turning claws, thus enabling preliminary cleaning of the rotary tiller and multiple turning claws before the cleaning component is used. This achieves pre-removal of large pieces of soil, reduces the amount of soil covering, lightens the cleaning burden on the cleaning component, and greatly improves the cleaning effect.

[0023] Preferably, two stabilizing rods are fixedly connected to the right side of the movable plate, and the right ends of the two stabilizing rods pass through the side plate located on the right side and are slidably connected to the side plate located on the right side.

[0024] Furthermore, by setting up stabilizing bars, the moving plate can be stably supported, improving the stability of the moving plate and multiple cleaning blocks.

[0025] The beneficial effects of this invention are: 1. By starting the high-pressure water pump, water can be drawn out from the water tank and transported through the first connector, the corrugated expansion pipe and the second connector. Then, water is sprayed through the high-pressure nozzle. In this way, the soil on the rotary tiller shaft and multiple tilling claws can be washed away, thereby preventing soil from covering the rotary tiller shaft and multiple tilling claws, reducing the running resistance of multiple tilling claws, and preventing multiple tilling claws from being damaged due to excessive resistance caused by soil. 2. By starting the second motor, the lead screw can be driven to rotate. When the lead screw rotates, it can drive the nut to move laterally. When the nut moves laterally, it can drive the slider, the adjusting box and the high-pressure nozzle to move laterally. When the high-pressure nozzle moves laterally, it can facilitate the high-pressure nozzle to thoroughly flush and clean the entire rotary tiller shaft and multiple tilling claws, improving the cleaning efficiency and effect of the rotary tiller shaft and multiple tilling claws. 3. By starting the third motor, the half-tooth gear can be driven to rotate. At this time, through the meshing transmission between the half-tooth gear and the drive gear, the drive gear can be driven to rotate counterclockwise. When the drive gear rotates counterclockwise, it can drive the rotating shaft to rotate counterclockwise, and the torsion spring can be twisted. When the plane on the drive gear corresponds to the half-tooth gear, the drive gear and the half-tooth gear disengage. Then, through the elastic reset characteristic of the torsion spring, the rotating shaft and the drive gear can be driven to rotate and reset. At this time, through the continuous rotation of the half-tooth gear and the cooperation between the torsion spring, the rotating shaft and the drive gear can be driven to rotate back and forth in both directions. When the drive gear rotates back and forth in both directions, it can drive the swing arm and the high-pressure nozzle to swing back and forth in both directions. When the high-pressure nozzle swings back and forth in both directions, it can increase the spray range of the high-pressure nozzle, thereby ensuring the cleanliness of the rotary tiller shaft and multiple turning claws and improving the cleaning effect. 4. By activating the four first hydraulic rods, the two dust baffles can be moved closer or further apart, thereby blocking the first sliding hole when the rotary tiller and multiple turning claws are turning the soil. The two adapter slots can also engage with the regulating box to achieve a complete fit, preventing dust and soil from entering the box and ensuring the stable operation of the transmission components. At the same time, when using the high-pressure nozzle, by opening the two dust baffles and releasing the obstruction limit on the regulating box and the high-pressure nozzle, the normal lateral movement of the regulating box and the high-pressure nozzle will not be affected. 5. By activating the second hydraulic rod, the moving plate can be driven to move. When the moving plate moves, it can drive multiple cleaning blocks to move. At this time, the corresponding turning claws can be inserted into two adjacent cleaning blocks, and then drive the rotary shaft and multiple turning claws to rotate. The cleaning blocks can scrape the soil off the rotary shaft and multiple turning claws, thus enabling preliminary cleaning of the rotary shaft and multiple turning claws before the cleaning component is used. This achieves pre-removal of large pieces of soil, reduces the amount of soil covering, reduces the cleaning burden on the cleaning component, and greatly improves the cleaning effect. This invention achieves efficient cleaning of the rotary tiller shaft and multiple tilling claws through a simple structure, reducing the amount of soil covering, alleviating the running resistance of the multiple tilling claws, preventing damage to the tilling claws due to excessive resistance caused by soil, and is easy to operate, highly automated, and practical.

The moving plate 40 is driven to move, and when the moving plate 40 moves, it can drive multiple cleaning blocks 41 to move. At this time, the corresponding turning claws 7 can be inserted into two adjacent cleaning blocks 41, and then drive the rotary shaft 6 and multiple turning claws 7 to rotate. The soil on the rotary shaft 6 and multiple turning claws 7 can be scraped off by the multiple cleaning blocks 41. Thus, the rotary shaft 6 and multiple turning claws 7 can be pre-cleaned before the cleaning component is used, realizing the pre-removal of large pieces of soil, reducing the amount of soil covering, reducing the cleaning burden of the cleaning component, and greatly improving the cleaning effect.

[0039] As a preferred embodiment, two stabilizing rods 42 are fixedly connected to the right side of the moving plate 40. The right ends of the two stabilizing rods 42 pass through the side plate 12 on the right side and are slidably connected to the side plate 12 on the right side. By setting the stabilizing rods 42, the moving plate 40 can be stably supported, thereby improving the stability of the moving plate 40 and the multiple cleaning blocks 41.

[0040] It should be noted that the specific models of track drive equipment 1, transmission rod 2, first motor 8, second motor 14, third motor 20, high-pressure nozzle 27, high-pressure water pump 32, first hydraulic rod 36, and second hydraulic rod 39 used can be selected by those skilled in the art. Furthermore, the above-mentioned track drive equipment 1, transmission rod 2, first motor 8, second motor 14, third motor 20, high-pressure nozzle 27, high-pressure water pump 32, first hydraulic rod 36, and second hydraulic rod 39 are all existing technologies and will not be elaborated upon in this solution.

[0041] Working Principle: The track drive unit 1 is used to move the entire tracked rotary tiller. The track drive unit 1, in conjunction with the transmission rod 2, drives the mounting plate 4, the rotary shaft 6, and multiple tilling claws 7 to move up and down. In operation, the first motor 8 is started to rotate the upper transmission wheel 9. Then, through the transmission between the two transmission wheels 9 and the transmission belt 10, the rotary shaft 6 is rotated. When the rotary shaft 6 rotates, it drives the multiple tilling claws 7 to rotate, thus performing rotary tillage and turning of the soil. When it is necessary to clean the rotary shaft 6 and the multiple tilling claws 7, the second hydraulic rod 39 is activated to move the moving plate 40. When the moving plate 40 moves, it drives... Multiple cleaning blocks 41 move, allowing the corresponding turning claws 7 to insert into adjacent cleaning blocks 41. This drives the rotary tiller 6 and the multiple turning claws 7 to rotate, scraping away soil from the rotary tiller 6 and the multiple turning claws 7 through the cleaning blocks 41. This allows for preliminary cleaning of the rotary tiller 6 and the multiple turning claws 7 before the cleaning components are used, achieving pre-removal of large clumps of soil, reducing the amount of soil covering, lessening the cleaning burden on the cleaning components, and greatly improving the cleaning effect. Then, by activating the high-pressure water pump 32, water is drawn from the water tank 30 and transported through the first connector 28, the corrugated telescopic pipe, and the second connector 33. Water is then sprayed through the high-pressure nozzle 27. In this way, the rotary tiller 6 and the multiple turning claws 7 can be cleaned. The soil-washing operation on the tilling claws 7 prevents soil from accumulating on the rotary tiller shaft 6 and multiple tilling claws 7, reducing the operating resistance of the tilling claws 7 and preventing damage due to excessive resistance caused by soil. Here, starting the second motor 14 drives the lead screw 15 to rotate. When the lead screw 15 rotates, it drives the nut 16 to move laterally. When the nut 16 moves laterally, it drives the slider 17, the adjusting box 19, and the high-pressure nozzle 27 to move laterally. When the high-pressure nozzle 27 moves laterally, it facilitates a thorough water flushing and cleaning of the entire rotary tiller shaft 6 and multiple tilling claws 7, improving the cleaning efficiency and effectiveness. Furthermore, starting the third motor 20 drives the semi-tooth... When gear 21 rotates, the meshing transmission between the half-gear 21 and the drive gear 23 drives the drive gear 23 to rotate counterclockwise. When the drive gear 23 rotates counterclockwise, it drives the shaft 22 to rotate counterclockwise, and the torsion spring 24 is twisted. When the drive gear 23 aligns with the plane on the half-gear 21, the drive gear 23 disengages from the half-gear 21. Then, through the elastic restoring characteristic of the torsion spring 24, the shaft 22 and the drive gear 23 can rotate and reset. Through the continuous rotation of the half-gear 21 and the cooperation of the torsion spring 24, the shaft 22 and the drive gear 23 can reciprocate in both directions. Then, when the drive gear 23 reciprocates in both directions...The system can drive the swing arm 25 and the high-pressure nozzle 27 to reciprocate in both directions. When the high-pressure nozzle 27 reciprocates, it increases the spray range of the high-pressure nozzle 27, thereby ensuring the integrity of cleaning the rotary tiller 6 and multiple turning claws 7 and improving the cleaning effect. Finally, by activating the four first hydraulic rods 36, the two dust baffles 37 can move closer or further apart, thus blocking the first sliding hole 18 when the rotary tiller 6 and multiple turning claws 7 are turning the soil. The two adapter slots 38 can also engage with the regulating box 19, achieving a complete fit and preventing dust and soil from entering the box 13, ensuring the stable operation of the transmission components. Furthermore, when using the high-pressure nozzle 27, opening the two dust baffles 37 and releasing the obstruction limit on the regulating box 19 and the high-pressure nozzle 27 will not affect the normal lateral movement of the regulating box 19 and the high-pressure nozzle 27.
