Description

Technical Field

[0001] This invention belongs to the field of agricultural tillage machinery technology, specifically referring to a soil-turning device for agricultural planting. Background Technology

[0002] Soil turning is the core of agricultural tillage, aiming to loosen the soil, uncover deep nutrients, and clear straw and weeds to create conditions for crop growth. Currently, soil turning devices on the market have many shortcomings, failing to meet the demands of refined and efficient tillage: First, they are functionally limited and inefficient, often only capable of turning soil, requiring additional straw processing, and integrated devices have poor connectivity; second, they lack adaptability, with fixed turning teeth and rudimentary depth adjustment, failing to adapt to different soil and crop needs; third, power transmission is unstable, open structures easily allow debris to enter, components wear out quickly, and multi-power source devices are costly and energy-intensive; fourth, operation and maintenance are inconvenient, disassembly and assembly are cumbersome, and replacement of vulnerable parts is costly. Summary of the Invention

[0003] In order to overcome the shortcomings of the prior art, the present invention provides a soil-turning device for agricultural planting, which effectively solves the above problems.

[0004] The technical solution adopted by this invention is as follows: This invention proposes a soil turning device for agricultural planting, including a soil turning and crushing structure, a straw crushing component, a power component, and a load-bearing component. The power component is located on the load-bearing component, the soil turning and crushing structure is located at the bottom rear side of the power component, and the straw crushing component is located at the bottom front side of the power component. The load-bearing component includes a frame and wheels, the wheels are located on the frame, the power component includes a drive motor, a transmission box, and a drive shaft, the transmission box is located on the frame, the drive motor is located above the transmission box, and the drive shaft is located at the bottom front and rear of the transmission box.

[0005] Furthermore, the transmission box is provided with a lifting rod, a triangular crossbeam and a rear crossbeam. The lifting rod is located at the top center, the triangular crossbeam is located at the front of the top, and the rear crossbeam is located at the rear of the top. The side wall of the rear crossbeam is provided with a plow plate. The transmission box is provided with a transmission wheel. The drive motor is located on the triangular crossbeam, and the output shaft of the drive motor is provided with a motor drive wheel.

[0006] Preferably, the drive shaft provides direct power output to the soil turning and crushing structure and the straw crushing component; the linear array installation ensures uniform force on the working parts; the drive columns at both ends of the drive shaft provide connection points for the drive belt, with a large transmission contact area to prevent the drive belt from slipping and improve the stability of power transmission; the transmission box provides protection for the internal drive wheels to prevent soil, straw and other debris from entering and causing transmission jamming, and to extend the life of the transmission components; the drive wheels and drive columns work together to achieve synchronous linkage of the front and rear drive shafts, ensuring the consistency of the rotation speed of straw crushing and soil turning and crushing operations, and improving the overall operation coordination.

[0007] Furthermore, the power assembly also includes a chain box and a drive shaft sleeve. The top of the chain box is mounted on a triangular crossbeam, and the drive shaft on the front side passes through the bottom of the chain box. The drive shaft sleeve is located at the center of the front drive shaft and is housed inside the chain box. Drive columns are provided at both ends of the drive shaft.

[0008] Preferably, the chain box provides enclosed protection for the internal drive shaft sleeve and drive belt, isolating them from field debris and preventing the drive belt from aging or jamming. The drive shaft sleeve is fitted onto the center of the front drive shaft, allowing the power of the motor drive wheel to be evenly transmitted to the drive shaft, avoiding localized deformation of the drive shaft and ensuring the coaxiality of the drive shaft rotation.

[0009] Furthermore, the motor drive wheel and the transmission shaft sleeve are connected by a transmission belt, the transmission column of the front transmission shaft is connected to the transmission wheel by a transmission belt, and the transmission column of the rear transmission shaft is connected to the transmission wheel by a transmission belt.

[0010] Furthermore, the soil turning and breaking structure includes soil turning tooth seats and adjustable soil turning teeth. The soil turning tooth seats are arranged in a linear array on the rear drive shaft. The soil turning tooth seats have a mounting bushing at the center. The mounting bushing is fixed to the drive shaft by fasteners. The soil turning tooth seats have a circular array of multi-hole fixing grooves. The adjustable soil turning teeth are fixed to the multi-hole fixing grooves by bolts.

[0011] Preferably, the mounting bushing is connected to the drive shaft via fasteners, facilitating easy installation and disassembly while maintaining high coaxiality to prevent eccentric vibration during the rotation of the turning teeth. The circular array of multi-hole fixing slots provides multiple installation options for the adjustable turning teeth, allowing for flexible adjustment of the tooth extension length and installation angle to suit different soil hardness (increase extension length for hard soil, decrease length for soft soil) and turning depth requirements, making it highly versatile. The teeth are securely fixed to the multi-hole fixing slots via bolts, and easy to replace; worn teeth can be replaced individually, reducing maintenance costs. The tooth structure design combines turning and crushing functions, simultaneously completing soil tillage and large clod impact crushing during rotation, achieving integrated turning and crushing without the need for separate crushing equipment, thus improving operational efficiency.

[0012] Furthermore, the straw crushing assembly includes a follower blade, a crushing blade, a rotating shaft seat, a side blade seat, and a soil-dividing plow. The side blade seats are symmetrically arranged on both sides of the rotating shaft seat, and the rotating shaft seat is linearly arrayed on the front drive shaft. The crushing blade is arranged on the side blade seat, the follower blade is arranged on the rotating shaft seat, and the top of the soil-dividing plow is provided with a top mounting rod, which is fixed to the plow plate by fasteners.

[0013] Preferably, the rotating base provides a pivot point for the follower blades, allowing them to rotate with the drive shaft and perform follow-up motion. This, combined with the crushing blades, creates a double-layer shearing effect, improving the thoroughness of straw crushing. The connecting holes of the mounting base precisely align with the side blade holders, and the second fixing hole ensures a secure fixation to the drive shaft, resulting in high installation accuracy and preventing component loosening during operation. The follower blades rotate to perform initial shearing and cutting of the straw, while the high-speed rotation of the crushing blades completes secondary fine crushing. Together, they achieve efficient crushing of straw and weeds in the field, and the crushed straw can be directly returned to the field. The crushing blades are installed independently and can be replaced individually after wear, resulting in low maintenance costs.

[0014] Furthermore, the rotating shaft seat has a rotating seat at its center, and mounting seats are provided on both sides of the rotating shaft seat. The mounting seats on both sides are symmetrically provided with connecting holes, and a second fixing hole is provided on one side of the mounting seat. The second fixing hole is fixed to the transmission shaft by fasteners, and the follower blade is sleeved on the rotating seat.

[0015] Furthermore, the side blade holder has a fixed seat and a blade holder on each side, respectively. The side blade holder has a mounting hole at its center, a rotating ring at the inner edge of the fixed seat, and a side mounting hole on the side wall of the blade holder. The fixed seat is nested on the mounting seat, and the connecting hole and the mounting hole are connected by fasteners. The rotating ring is attached to the side wall of the follower blade. The crushing blade has a fixing groove plate at its center, and a fixing hole is provided on the fixing groove plate. The fixing hole and the side mounting hole are connected by fasteners.

[0016] Preferably, the fixing seat is nested on the mounting seat, with a firm connection and high coaxiality, avoiding eccentricity when the blade rotates; the rotating ring on the inner wall of the fixing seat fits against the side wall of the follower blade, changing the sliding friction of the follower blade into rolling friction, greatly reducing rotational resistance and energy consumption, while ensuring the smooth rotation of the follower blade; the side mounting hole of the blade holder precisely matches the fixing groove plate of the crushing blade, realizing the quick installation / removal of the crushing blade and improving the debugging efficiency before operation.

[0017] Furthermore, the front end of the frame is provided with a travel connecting seat, the top center of the frame is provided with a lifting crossbeam, the lifting crossbeam is provided with a depth adjustment device, the depth adjustment device is provided with an adjustment handwheel and an adjustment screw, the adjustment screw is located at the bottom of the adjustment handwheel and passes through the lifting crossbeam, and the adjustment handwheel rotates on the lifting crossbeam.

[0018] Furthermore, the lifting rod is provided with a locking rod, a threaded hole and a limiting nut. The locking rod is symmetrically arranged on the top of the lifting rod and passes through the lifting crossbeam and is fixed by the limiting nut. The threaded hole is located at the center of the lifting rod and is connected to the adjusting screw by a thread.

[0019] Preferably, a screw drive system is used, allowing for manual adjustment of the power unit's raising and lowering by turning the adjustment handwheel. This simple operation requires no additional power and is suitable for field work environments without electricity. The screw drive offers high adjustment precision, enabling fine adjustments to the tilling and pulverizing depth to meet the soil depth requirements of different crops (e.g., shallow tillage for shallow-rooted crops, deep tillage for deep-rooted crops). The threaded holes of the adjustment screw and the lifting rod fit tightly, ensuring zero backlash and no depth deviation during operation, guaranteeing consistency in field work. Locking rods on both sides guide the movement of the lifting rod, preventing deviation during raising and lowering. Limit nuts provide double locking of the position after raising and lowering, ensuring no loosening during operation and maintaining consistent working depth.

[0020] The beneficial effects achieved by the present invention using the above structure are as follows: 1. The device adopts a layout design of front crushing and rear tillage. The front straw crushing component can complete the double-layer efficient crushing of straw and weeds in the field, realizing the return of straw to the field on the spot. The rear soil turning and crushing structure simultaneously completes soil turning and soil clod crushing. The soil divider plow opens the furrows and rows in advance to assist the tillage operation. All components are connected and cooperate with each other, eliminating the need for separate straw cleaning, soil crushing and other processes. It completes the preparation and core operation before tillage in one stop, greatly improving the efficiency of field operation.

[0021] 2. The extension length and installation angle of the turning teeth can be flexibly adjusted through the multi-hole fixing groove on the turning tooth seat to adapt to different soil hardness and tillage needs; the depth adjustment device realizes precise fine adjustment and locking of the working depth through the screw drive, and the soil plow rises and falls synchronously with the power component, which can match the planting soil depth requirements of different crops such as shallow roots and deep roots, and can adapt to a variety of farmland scenarios and planting needs, with extremely strong versatility.

[0022] 3. Using a single drive motor as the core power source, the synchronous linkage of the front and rear drive shafts is achieved through the transmission belt. The transmission path is short, the power transmission loss is small, and the speed consistency of straw crushing and soil turning is guaranteed. The transmission box and chain box enclose and protect the internal transmission wheels, transmission shaft sleeves and other components to prevent soil, straw and other debris from entering and causing jamming and wear. The cooperation between the transmission column and the transmission belt increases the contact area, effectively preventing slippage, and ensuring good stability and continuity of power transmission.

[0023] 4. The travel coupling seat at the front of the frame can be quickly connected or disconnected from external traction equipment such as tractors, and the operation is simple; the depth adjustment is completed by manually adjusting the handwheel, without the need for additional power, which is suitable for field operation environments without power; the crushing blades, adjustable turning teeth and other vulnerable parts are all independently installed structures, which can be disassembled and replaced individually without the need for overall disassembly and assembly, resulting in low maintenance costs; the connection method of each component is simple, and daily maintenance operations such as cleaning and lubrication are convenient, which meets the actual use needs of farmland operations.

The transmission box 33 is mounted on the frame 41, the drive motor 31 is located above the transmission box 33, and the transmission shaft 34 is located at the front and rear bottoms of the transmission box 33.

[0030] A lifting rod 331, a triangular crossbeam 332, and a rear crossbeam 333 are provided between the transmission box 33. The lifting rod 331 is located at the top center, the triangular crossbeam 332 is located at the front of the top, and the rear crossbeam 333 is located at the rear of the top.

The drive motor 31 is mounted on the triangular crossbeam 332, and a motor drive wheel 311 is provided on the output shaft of the drive motor 31.

[0031] The power assembly 3 also includes a chain box 32 and a drive shaft sleeve 35. The top of the chain box 32 is mounted on the triangular crossbeam 332, and the drive shaft 34 on the front side passes through the bottom of the chain box 32. The drive shaft sleeve 35 is located at the center of the drive shaft 34 on the front side and is located inside the chain box 32. The drive shaft 34 has drive columns 341 at both ends.

[0032] The motor drive wheel 311 is connected to the transmission shaft sleeve 35 by a transmission belt. The transmission column 341 of the front transmission shaft 34 is connected to the transmission wheel 334 by a transmission belt, and the transmission column 341 of the rear transmission shaft 34 is connected to the transmission wheel 334 by a transmission belt.

[0033] The soil turning and breaking structure 1 includes a soil turning tooth seat 11 and adjustable soil turning teeth 12. The soil turning tooth seat 11 is linearly arranged on the drive shaft 34 at the rear. The center of the soil turning tooth seat 11 is provided with a mounting sleeve 111, which is fixed to the drive shaft 34 by fasteners. The soil turning tooth seat 11 is provided with a circular array of multi-hole fixing grooves 112, and the adjustable soil turning teeth 12 are fixed to the multi-hole fixing grooves 112 by bolts.

[0034] The straw crushing assembly 2 includes a follower blade 21, a crushing blade 22, a rotating shaft seat 23, a side blade seat 24, and a soil dividing plow 25. The side blade seats 24 are symmetrically arranged on both sides of the rotating shaft seat 23. The rotating shaft seat 23 is linearly arranged on the front drive shaft 34. The crushing blade 22 is arranged on the side blade seat 24, and the follower blade 21 is arranged on the rotating shaft seat 23. The top of the soil dividing plow 25 is provided with a top mounting rod 251, which is fixed to the plow plate 3331 by fasteners.

[0035] The rotating shaft seat 23 has a rotating seat 231 at its center, and mounting seats 232 on both sides of the rotating shaft seat 23. The mounting seats 232 on both sides are symmetrically provided with connecting holes 2321. The mounting seat 232 on one side is provided with a fixing hole 2322. The fixing hole 2322 is fixed to the transmission shaft 34 by fasteners. The follower blade 21 is sleeved on the rotating seat 231.

[0036] The side blade holder 24 has a fixed seat 241 and a blade holder 242 on both sides. The side blade holder 24 has a mounting hole 243 at its center. The fixed seat 241 has a rotating ring 244 at its inner edge. The blade holder 242 has a side mounting hole 245 on its side wall. The fixed seat 241 is nested on the mounting seat 232, and the connecting hole 2321 is connected to the mounting hole 243 by fasteners. The rotating ring 244 is attached to the side wall of the follower blade 21. The crushing blade 22 has a fixed groove plate 221 at its center. The fixed groove plate 221 has a fixed hole 222, and the fixed hole 222 is connected to the side mounting hole 245 by fasteners.

[0037] The front end of the frame 41 is provided with a travel connecting seat 411, and the top center of the frame 41 is provided with a lifting crossbeam 412. The lifting crossbeam 412 is provided with a depth adjustment device 43. The depth adjustment device 43 is provided with an adjustment handwheel 431 and an adjustment screw 432. The adjustment screw 432 is located at the bottom of the adjustment handwheel 431 and passes through the lifting crossbeam 412. The adjustment handwheel 431 rotates on the lifting crossbeam 412.

[0038] The lifting rod 331 is provided with a locking rod 3311, a threaded hole 3312 and a limiting nut 3313. The locking rod 3311 is symmetrically arranged on the top of the lifting rod 331, and the locking rod 3311 passes through the lifting crossbeam 412 and is fixed by the limiting nut 3313. The threaded hole 3312 is located at the center of the lifting rod 331, and the threaded hole 3312 is connected to the adjusting screw 432 by threads.

[0039] In practical use, depending on the required tillage depth and soil hardness for agricultural planting, the adjustable tillage teeth 12 are fixed to the corresponding holes in the multi-hole fixing groove 112 of the tillage tooth base 11 with bolts. The extension angle and length of the adjustable tillage teeth 12 are adjusted, and the bolts are tightened to ensure a firm fixation. If the soil is too hard, the extension length of the adjustable tillage teeth 12 can be increased. If it is a shallow tillage operation, the extension length can be reduced.

[0040] Rotating the adjustment handwheel 431 of the depth adjustment device 43 drives the adjustment screw 432 to rotate. The adjustment screw 432 engages with the threaded hole 3312 of the lifting rod 331, causing the lifting rod 331 to move vertically up and down along the locking rod 3311. This, in turn, causes the transmission box 33, transmission shaft 34, and the straw crushing component 2 and the soil turning and crushing structure 1 below to rise and fall synchronously. The soil-dividing plow 25 rises and falls synchronously with the plow plate 3331. After adjusting to the preset soil turning depth, tighten the limit nuts 3313 on both sides of the lifting crossbeam 412 to lock the lifting rod 331 and prevent structural displacement during operation. The traction end of the external traction equipment is securely connected to the travel connection seat 411 at the front end of the frame 41 using pins and other connecting parts to ensure that the device does not fall off during travel.

[0041] When the drive motor 31 is powered on, the drive motor 31 starts and drives the motor drive wheel 311 on the output shaft to rotate. The motor drive wheel 311 drives the transmission shaft sleeve 35 to rotate through the transmission belt, which in turn drives the front transmission shaft 34 to rotate. The transmission columns 341 at both ends of the front transmission shaft 34 drive the transmission wheel 334 in the transmission box 33 to rotate through the transmission belt. The transmission wheel 334 then drives the transmission column 341 of the rear transmission shaft 34 to rotate through the transmission belt, thus achieving synchronous high-speed rotation of the front and rear transmission shafts 34.

[0042] The traction device drives the unit to move at a constant speed along the field operation path. The straw crushing component 2 at the front of the device first contacts the straw and weeds in the field. The drive shaft 34 at the front drives the linear array of rotating shaft seats 23 to rotate synchronously. The follower blades 21 on the rotating shaft seats 23 rotate with the movement of the device on the rotating seat 231. At the same time, the side blade seat 24 drives the crushing blades 22 to rotate at high speed. The follower blades 21 and the crushing blades 22 work together to cut and crush the straw and weeds, realizing on-site crushing of straw in the field. The rotating ring 244 fits against the side wall of the follower blades 21, effectively reducing the frictional resistance during the rotation of the follower blades 21 and ensuring the smoothness of the crushing operation. At the same time, the soil divider 25 moves with the device to divide the soil into rows and ditches, and pushes the soil to both sides to prepare for subsequent tilling operations.

[0043] As the device continues to move forward, the drive shaft 34 at the rear drives the linear array of turning teeth 11 to rotate at high speed. The adjustable turning teeth 12 on the turning teeth 11 are inserted into the soil to turn over the soil after it has been divided into rows, turning the lower soil to the surface. At the same time, the adjustable turning teeth 12 impact and break up large clods of soil during rotation, realizing the integrated operation of turning and breaking up soil. The soil texture after turning is uniform and meets the soil requirements for agricultural planting.

[0044] During operation, if changes in soil moisture or a sudden increase in straw volume occur, the travel speed can be adjusted using the traction equipment to ensure the effectiveness of straw crushing and soil turning. If the turning depth needs to be adjusted temporarily, the limit nut 3313 can be loosened and the adjusting handwheel 431 can be rotated for fine adjustment. After adjustment, the limit nut 3313 should be tightened again. When encountering obstacles such as stones or tree roots in the field, the machine should be stopped in time, the obstacles should be cleared, and the operation should continue to prevent damage to the blades, turning teeth, and transmission structure.
