Description

Technical Field

[0001] This invention belongs to the field of agricultural machinery technology, specifically a multi-functional paddy field stubble burying, slurry lifting, and leveling machine. Background Technology

[0002] Paddy field preparation is a crucial step in rice production, and the quality of this work directly affects the growth of rice. Paddy field stubble burying is a common farming technique in rice cultivation, which refers to burying the remaining rice stubble in the soil after rice harvest.

[0003] The multi-functional paddy field stubble burying and leveling machine is a type of machinery used in paddy field agricultural production. It is mainly used to complete multiple tasks in paddy field operations, especially in the process of cultivating and leveling paddy fields. It combines multiple functions, which can effectively improve work efficiency and reduce labor intensity. Furthermore, paddy field stubble burying is a technology that has both economic and ecological benefits. It improves soil organic matter content, soil structure, reduces pests and diseases, and enhances crop yield and quality.

[0004] Currently, most mainstream paddy field tillage machinery is based on rotary tillers, equipped with components such as leveling harrows or leveling shovels. It mainly relies on high-speed rotating rotary tiller rollers to break up the soil and bury the stubble. The rotary tiller blades cut and throw the rice stubble by rotating at high speed, but cannot compress it downwards. As a result, some rice stubble is broken up but still floats on the surface, making it difficult to bury deeply and affecting rice transplanting. Therefore, it needs to be improved. Summary of the Invention

[0005] To address the problem mentioned in the background technology that the rice stubble cannot be compressed downwards, resulting in some of the stubble remaining on the surface after being chopped up and difficult to bury deeply, thus affecting rice transplanting, this invention provides a multi-functional paddy field stubble burying and leveling machine.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a multi-functional paddy field stubble burying and leveling machine, comprising a support shell, a soil-breaking component fixedly installed on the inner side of the support shell, a control component provided at the upper end of the support shell, a leveling component fixedly installed on the side of the support shell near the control component, a drive component fixedly installed on the top of the support shell, a fixing frame fixedly installed on the top of the support shell, and a suspension component fixedly installed on the top of the fixing frame. The soil-breaking component includes a first connecting shaft and a second connecting shaft. A plurality of rotating units and connecting units are fixedly installed on the outer wall of the first connecting shaft, and the rotating units and connecting units are staggered. Two rotating components are fixedly installed on the outer wall of the second connecting shaft.

[0007] Preferably, the rotating unit includes a connecting ring, a vertical block is fixedly installed on the outer wall of the connecting ring, and fixing members are fixedly installed on both sides of the outer wall of the vertical block.

[0008] Preferably, the connecting unit includes a connecting plate, a second spring is fixedly installed at the bottom of the connecting plate, a connector is fixedly installed at the end of the second spring, and an eccentric block is fixedly installed on the outer wall of the first connecting shaft.

[0009] Preferably, a servo motor is fixedly connected to the end of the first connecting shaft, a transmission component is provided on the outer wall of the first connecting shaft, and a second connecting shaft is connected to the end of the transmission component away from the first connecting shaft. Both the first connecting shaft and the second connecting shaft are movably connected to the support housing.

[0010] Preferably, the control component includes a control board, a hydraulic rod is fixedly installed between the support housing and the control board, a fixing groove is provided on the top of the support housing, and the control board and the support housing are movably connected.

[0011] Preferably, the leveling component includes a leveling piece, a fixing block is fixedly installed on the top surface of the leveling piece, a pneumatic cylinder is provided at the upper end of the fixing block, the pneumatic cylinder is fixedly connected to the support housing, and the inner wall of the leveling piece is set as a smooth arc shape.

[0012] Preferably, the end of the movable block is set as an inclined surface, the upper end of the soil crushing component is provided with a through hole, the movable block is movably connected to the soil crushing component, and a groove is provided on one side of the movable block.

[0013] Preferably, the eccentric block is fixedly connected to the first connecting shaft, the top of the connecting plate is fixedly connected to the supporting shell, the connecting member is in abutting connection with the eccentric block, and the bottom of the connecting member is provided with rigid comb teeth, and the phases of adjacent rows of rigid comb teeth are staggered.

[0014] Preferably, the bottom of the movable block and both sides of the vertical plate are provided with sliders, and the bottom and both sides of the fixing member are provided with sliding grooves, and the movable block and the vertical plate are movably connected to the fixing member.

[0015] Preferably, the outer walls of both rotating parts are fixedly equipped with helical blades, and the helical blades are in opposite directions. The connecting ring is fixedly connected to the first connecting shaft, and the supporting shell is made of stainless steel.

[0016] Compared with the prior art, the beneficial effects of the present invention are as follows: This invention, through the cooperation of structures such as a rotating unit and a connecting unit, allows the rotating unit to cut and throw the rice stubble, while the rigid comb teeth of the connecting unit vibrate and gradually insert the raised rice stubble into the soil, effectively grabbing and scooping the rice stubble and pressing it downward into the soil layer to achieve forced deep burial. At the same time, the vibration helps to break up soil clods.

[0017] This invention, through the combination of a first spring and a vertical block, allows for the rapid replacement of the soil-crushing components. Timely replacement of the cutter head ensures that the equipment operates in optimal condition, reducing operational downtime and power waste caused by cutter head dulling. This extends the overall service life of the equipment, reduces the frequency of maintenance and replacement of other parts, and improves soil-crushing efficiency.

[0018] This invention, through the coordination of transmission and rotating components, allows the rotating component to transport excess soil to both sides. When the spiral blades rotate, they exert a strong shearing force on the soil. Especially when the soil is hard or sticky, the spiral blades can break the soil through repeated cutting and compression, thereby effectively breaking up larger soil clumps and improving the looseness of the soil.

[0021] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0022] like Figures 1 to 10 As shown, the present invention provides a multifunctional paddy field stubble burying and leveling machine, including a support shell 1, a soil breaking component 2 fixedly installed on the inner side of the support shell 1, a control component 3 provided at the upper end of the support shell 1, a leveling component 4 fixedly installed on the side of the support shell 1 near the control component 3, a drive component 5 fixedly installed on the top of the support shell 1, a fixing frame 6 fixedly installed on the top of the support shell 1, and a suspension component 7 fixedly installed on the top of the fixing frame 6. The soil breaking component 2 includes a first connecting shaft 22 and a second connecting shaft 24. A plurality of rotating units 25 and connecting units 26 are fixedly installed on the outer wall of the first connecting shaft 22, and the rotating units 25 and connecting units 26 are staggered. Two rotating components 27 are fixedly installed on the outer wall of the second connecting shaft 24. A servo motor 21 is fixedly connected to the end of the first connecting shaft 22. A transmission component 23 is provided on the outer wall of the first connecting shaft 22. The end of the transmission component 23 away from the first connecting shaft 22 is connected to the second connecting shaft 24. Both the first connecting shaft 22 and the second connecting shaft 24 are movably connected to the support shell 1.

[0023] The above scheme is adopted: through the cooperation of rotating unit 25 and rotating component 27, the device is connected to the tractor via suspension component 7. Servo motor 21 is started, driving the first connecting shaft 22 to rotate. The first connecting shaft 22 drives the transmission component 23 and the second connecting shaft 24 to rotate. The first connecting shaft 22 drives rotating unit 25 and connecting unit 26 to rotate. The connecting unit 26 and rotating unit 25 are installed alternately, with the connecting unit 26 positioned slightly behind the rotating unit 25, and the two not on the same horizontal line. This allows the connecting unit 26 to better bury the rice stubble in the soil. Rotating unit 25 breaks up the soil. When connecting unit 26 moves downwards, the rigid comb teeth at the bottom of connecting unit 26 effectively grab and scoop up the buried stubble and press it downwards into the soil layer, achieving forced deep burial. Simultaneously, the vibration of the rigid comb teeth helps break up soil clods, and compared to rotary tillage, it causes less soil disturbance and significantly reduces energy consumption. Furthermore, after the soil is broken up by the rigid comb teeth, soil compaction can be effectively alleviated. The problem is that it helps to make the soil particles finer, which can enhance the soil's water retention capacity. At the same time, the first connecting shaft 22 drives the transmission component 23 and the rotating component 27 to rotate. The rotating component 27 transports excess soil to both sides. When the spiral blades rotate, they will apply a strong shearing force to the soil. Especially when the soil is relatively hard or sticky, the spiral blades can split the soil through repeated cutting and pressing, thereby effectively breaking up larger soil clumps. During the process of the soil being transported to both sides, the friction and collision forces generated will gradually disperse the soil particles, reduce the compactness of the soil clumps, and thus improve the looseness of the soil. The control component 3 moves up and down by sensing the amount of soil. Then, the leveling component 4 levels the soil after the stubble is buried, which can squeeze the stubble downward so that the stubble can be better buried in the soil and will not remain on the surface. The drive component 5 controls the power supply of the entire leveling machine. When an adverse situation occurs, the device can be quickly switched on and off by controlling the drive component 5.

[0024] like Figures 6 to 9 As shown, the rotating unit 25 includes a connecting ring 251, a vertical block 252 is fixedly installed on the outer wall of the connecting ring 251, and fixing members 253 are fixedly installed on both sides of the outer wall of the vertical block 252. A movable block 254 is provided in the inner cavity of the fixing member 253, and a vertical plate 255 is fixedly installed on the top surface of the movable block 254. A first spring 256 is elastically connected between the vertical plate 255 and the fixing member 253. A soil crushing member 257 is movably connected to the inner cavity of the vertical block 252. The first spring 256 includes a connecting plate 261, a second spring 262 is fixedly installed at the bottom of the connecting plate 261, a connecting member 263 is fixedly installed at the end of the second spring 262, and an eccentric block 264 is fixedly installed on the outer wall of the first connecting shaft 22.

[0025] Using the above solution: Through the cooperation of the rotating unit 25 and the connecting unit 26, when the soil-breaking component 257 has been used for a long time, it needs to be replaced. The movable block 254 is pulled to both sides, causing it to engage with the soil-breaking component 257. Then, the soil-breaking component 257 is moved downwards, connecting the replaced component 257 to the vertical block 252. The soil-breaking component 257 is then pushed upwards, causing it to abut against the movable block 254. When the soil-breaking component 257 abuts against the movable block 254, the soil-breaking component... 257 moves upward to abut against movable block 254. The two movable blocks 254 drive the vertical plate 255 to move to both sides, pressing against the first spring 256. When the movable block 254 engages with the through hole of the soil-crushing component 257, the first spring 256 drives the vertical plate 255 and movable block 254 to reset, thus quickly replacing the soil-crushing component 257. Timely replacement of the cutter head ensures the equipment operates in optimal condition, improves soil-crushing efficiency, reduces work stoppages and power waste caused by cutter head dulling, and reduces the risk of damage due to cutter head dulling. The damaged head prevents excessive wear and tear on the equipment, protecting other machine components from damage and extending the overall lifespan of the equipment. This reduces the frequency of maintenance and replacement of other parts. The new cutter head ensures the quality of each operation, resulting in more uniform and thorough soil pulverization, thus improving the soil's adaptability for planting. The first connecting shaft 22 rotates while simultaneously driving the eccentric block 264 to rotate. The eccentric block 264 abuts against the connecting piece 263, causing it to move downwards. When the eccentric block 264 no longer abuts against the connecting piece 263, the second spring 262 drives the connecting piece 263 to reset. As the connecting piece 263 moves downwards, the rigid comb teeth at the bottom of the connecting piece 263 effectively grab and pick up the buried stubble and press it downwards into the soil layer, achieving forced deep burial. Simultaneously, the vibration of the rigid comb teeth helps break up soil clods, and compared to rotary tillage, it causes less soil disturbance and significantly reduces energy consumption. Furthermore, after being treated by the rigid comb teeth, the soil compaction problem can be effectively alleviated, resulting in finer soil particles and enhanced soil water retention capacity.

[0026] like Figure 9 and Figure 10 As shown, the control component 3 includes a control plate 31, a hydraulic rod 32 is fixedly installed between the support housing 1 and the control plate 31, a fixing groove 33 is opened on the top of the support housing 1, the control plate 31 and the support housing 1 are movably connected, the leveling component 4 includes a leveling piece 41, a fixing block 42 is fixedly installed on the top surface of the leveling piece 41, a pneumatic cylinder 43 is provided at the upper end of the fixing block 42, the pneumatic cylinder 43 is fixedly connected to the support housing 1, and the inner wall of the leveling piece 41 is set as a smooth arc.

[0027] The above scheme is adopted: through the cooperation of control component 3 and leveling component 4, when there is a lot of soil during stubble burial and the rotating part 27 does not convey it to both sides in time, a soil sensor is set at the lower end of control plate 31. The soil sensor at the lower end of control plate 31 senses the amount of soil at the front end of control plate 31, thereby controlling hydraulic rod 32 to drive control plate 31 to move up and down. When control plate 31 moves in fixed groove 33, fixed groove 33 limits control plate 31, making control plate 31 more stable during movement. According to the leveling conditions, the position of leveling component 41 is adjusted before use, and then started. The pneumatic cylinder 43 adjusts the position and height of the leveling component 41 to adapt it to the land, thereby enabling better leveling. The pneumatic cylinder 43 is fixedly connected to the support housing 1, thereby fixing the leveling component 4. The smooth arc design inside the leveling component 41 reduces soil compaction by applying force evenly, especially in moist soil environments, thus protecting the soil structure and making maintenance more convenient. The smooth design reduces friction with the soil, thereby reducing the adhesion between the soil and the leveling component 41, making cleaning and maintenance of the leveling component 41 easier.

[0028] like Figure 6 and Figure 7 As shown, the end of the movable block 254 is set as an inclined surface, the upper end of the soil crushing component 257 is provided with a through hole, the movable block 254 is movably connected to the soil crushing component 257, a groove is provided on one side of the movable block 254, sliders are provided on the bottom of the movable block 254 and both sides of the vertical plate 255, and sliding grooves are provided on the bottom and both sides of the fixing component 253. The movable block 254 and the vertical plate 255 are movably connected to the fixing component 253.

[0029] The above solution employs the following design: Through the design of the first spring 256 and the inclined surface of the movable block 254, when the soil-breaking component 257 needs to be replaced, pushing the soil-breaking component 257 upwards causes it to move upwards and contact the movable block 254. The two movable blocks 254 then move the vertical plate 255 to both sides, compressing the first spring 256. The first spring 256 has sufficient elasticity to prevent the soil-breaking component 257 from falling or shaking during operation. When the movable block 254 engages with the through hole of the soil-breaking component 257, the first spring 256 drives the vertical plate 255 and the movable block 254 to reset, thus quickly replacing the soil-breaking component. Replace the soil crushing component 257. Timely replacement of the cutter head ensures that the equipment operates in optimal condition, improves soil crushing efficiency, reduces work stoppages and power waste caused by cutter head dulling, and reduces excessive wear of the equipment caused by cutter head damage, protecting other parts of the machine from damage, thereby extending the overall service life of the equipment and reducing the frequency of maintenance and replacement of other parts. The bottom of the movable block 254 and the two side sliders of the vertical plate 255 cooperate with the sliding groove of the fixed component 253 to limit the movement of the movable block 254 and the vertical plate 255, making them more stable during movement and preventing shaking during movement.

[0030] like Figure 3 , Figure 7 and Figure 8 As shown, the eccentric block 264 is fixedly connected to the first connecting shaft 22, the top of the connecting plate 261 is fixedly connected to the support housing 1, the connecting piece 263 is in contact with the eccentric block 264, the bottom of the connecting piece 263 is provided with rigid comb teeth, and the phases of the two adjacent rows of rigid comb teeth are staggered. The outer walls of the two rotating parts 27 are fixedly installed with helical blades, and the directions of the helical blades are opposite. The connecting ring 251 is fixedly connected to the first connecting shaft 22, and the support housing 1 is made of stainless steel.

[0031] The above scheme employs the following method: The eccentric block 264 is fixedly connected to the first connecting shaft 22 through its cooperation. When the first connecting shaft 22 rotates, causing the eccentric block 264 to rotate, the eccentric block 264 abuts against the connecting member 263, causing the connecting member 263 to move downwards. When the eccentric block 264 no longer abuts against the connecting member 263, the second spring 262 drives the connecting member 263 to reset. As the connecting member 263 moves downwards, the rigid comb teeth at the bottom of the connecting member 263 effectively grab and pick up the buried stubble and press it downwards into the soil layer, achieving forced deep burial. Simultaneously, the vibration of the rigid comb teeth helps break up soil clods, and compared to rotary tillage, it causes less soil disturbance and significantly reduces energy consumption. Furthermore, after the soil is broken up by the rigid comb teeth, it effectively alleviates soil compaction, helps the soil particles become finer, and enhances the soil's water retention capacity. The two rotating parts 27 have spiral blades with opposite directions. After the plant stubble is buried underground, excess soil accumulates on the surface. The design of the two opposing spiral blades helps to transport the excess soil to both sides, effectively dispersing the soil and preventing it from concentrating on one side to form uneven soil accumulation, resulting in a smoother ground surface. This accelerates the land leveling process and reduces uneven soil surface, making subsequent crop planting and management more efficient and reducing the need for secondary adjustments. The connecting ring 251 is fixedly connected to the first connecting shaft 22, so that the rotation of the first connecting shaft 22 drives the connecting ring 251 to rotate, thereby allowing the rotating unit 25 to better break up the soil. The support shell 1 is made of stainless steel, which does not contain harmful substances and has good chemical stability, reducing the risk of harmful substance pollution caused by metal corrosion. The surface is smooth and hard, making it easy to clean and less prone to stains. It also has high mechanical strength and durability, extending its service life.
