Description

Technical Field

[0001] This invention relates to the field of agricultural machinery. More specifically, this invention relates to a composite vibratory rat-track plow. Background Technology

[0002] Rat tunnel drainage technology is an effective underground drainage measure for farmland. It creates deep cavities in the soil to drain excess groundwater or perched water from the surface, thereby lowering the water table, improving soil aeration, and promoting crop root growth. In areas with high rainfall or high water tables, soil waterlogging is a major factor limiting agricultural production. The underground drainage system created by rat tunnel plows can effectively solve this problem, significantly increasing crop yields and the sustainable use of farmland.

[0003] Existing rat track plows are mainly divided into two categories: towed and suspended. Towed rat track plows rely on a tractor for support, using plow blades to cut the soil and a sculptor to create rat tracks. Suspended rat track plows are connected to the tractor via a three-point suspension system, with the tractor's hydraulic system controlling their raising and lowering during operation. In recent years, vibratory rat track plows have gradually gained application. These plows use a vibration mechanism on the frame to cause the entire frame and all plow heads to vibrate together, thereby reducing soil resistance and improving soil penetration. This overall vibration method is effective in clay and heavy loam soils and represents the main development direction for current rat track plow technology.

[0004] However, existing vibratory ratchet plows have significant shortcomings. First, the overall vibration mode results in dispersed vibration energy, with the frame itself consuming a large amount of energy during vibration, leaving a low percentage of energy actually used for soil cutting. Second, the intense vibration of the entire frame is directly transmitted to the tractor through the suspension system, severely impacting driving comfort and the lifespan of critical tractor components. Third, all plowshares use a uniform vibration frequency and amplitude, making it impossible to differentiate adjustments based on the soil hardness encountered by different plowshares, resulting in poor adaptability. Furthermore, the overall vibration places extremely high demands on the fatigue strength of the frame structure, easily leading to frame cracking and high equipment maintenance costs.

[0005] Therefore, it is necessary to propose a novel composite vibration rat plow to solve the above-mentioned problems existing in the prior art. Summary of the Invention

[0006] This invention provides a composite vibratory rat-track plow, which achieves energy concentration, drag reduction and efficiency improvement, comfort and durability through an independent vibrating plow head, elastic suspension vibration isolation and composite impact mechanism.

[0007] To achieve these objectives and other advantages according to the invention, according to one aspect of the invention, a composite vibratory rat-path plow is provided, comprising: a frame for connection to a traction vehicle; a power source fixedly mounted on the frame; at least one suspension damping assembly mounted on the frame; at least one plow handle, the upper end of which is connected to the suspension damping assembly, and the lower end of which is connected to a plowshare, the plowshare having a cylindrical structure and a receiving cavity therein, wherein a rotating shaft is rotatably supported within the receiving cavity by bearings, and an eccentric block is provided on the shaft body of the rotating shaft; a flexible shaft corresponding to each plowshare, the first end of which is drivenly connected to the rear end of the rotating shaft, and the second end of which is drivenly connected to the power source, the shaft body of which is located at the rear of the plow handle; and a rat-path extruder flexibly connected to the rear of the plowshare.

[0008] Preferably, the suspension shock absorption assembly includes a distribution beam and a leaf spring assembly, the beam body of the distribution beam is mounted on the frame, the leaf spring assembly is mounted on the distribution beam, and the upper end of the plow handle is connected to the leaf spring assembly.

[0009] Preferably, each of the suspension shock absorber assemblies includes two leaf spring assemblies spaced apart front to back. The leaf spring assembly located in front is connected to the upper end of the plow handle, and the leaf spring assembly located in the rear is connected to an inclined support.

[0010] Preferably, a connecting plate is provided at the upper end of the inclined support and the upper end of the plow handle. The connecting plate is in contact with the lowermost plate of the corresponding leaf spring assembly. A limiting block is provided above the uppermost plate of each leaf spring assembly. The connecting plate and the corresponding limiting block are fastened together by at least one U-bolt. The arc-shaped bend of the U-bolt is wrapped around the limiting block and the leaf spring assembly. After the threaded part of the U-bolt passes through the connecting plate, the connecting plate, the leaf spring assembly and the limiting block are clamped and fixed by a nut.

[0011] Preferably, at least one constraint ring is provided at intervals along the length of the rear part of the inclined support, and the shaft of the flexible shaft passes through the constraint ring in sequence.

[0012] Preferably, the distribution beam includes two C-shaped steel sections arranged opposite to each other, with the leaf spring assembly installed between the two C-shaped steel sections. The front lugs of the two leaf spring assemblies are installed between the two C-shaped steel sections via hinge supports. A connecting rod assembly is connected between the rear lugs of the two leaf spring assemblies. The connecting rod assembly includes two triangular lifting lug brackets and a force transmission connecting rod. The triangular lifting lug brackets have a first hinge portion, a second hinge portion, and a third hinge portion arranged in a triangle. The first hinge portion is rotatably installed between the two C-shaped steel sections. The second hinge portion is rotatably connected to the corresponding rear lug. The two ends of the force transmission connecting rod are rotatably connected to the third hinge portions of the two triangular lifting lug brackets, respectively.

[0013] Preferably, the device includes several plow handles arranged side by side along the width of the frame. A first gearbox and several second gearboxes are fixedly mounted on the frame. The first gearbox is located in the middle of the several second gearboxes. The first gearbox has two power output ends connected to drive shafts. The two drive shafts extend to the arrangement direction of the plow handles on both sides. The power input end of each second gearbox is connected to the drive shaft. The power output end of each second gearbox is connected to the second end of a corresponding flexible shaft. The power input end of the first gearbox is connected to the power source.

[0014] Preferably, the plowshare includes: a cylindrical body, the outer wall of which is fixedly connected to the lower end of the plow handle; a first support and a second support are axially spaced on the inner wall of the cylindrical body, each of the first and second supports being provided with a bearing, the inner ring of which is used to support the rotating shaft; an eccentric block located between the first and second supports; a head end, threadedly connected to the front end of the cylindrical body; a rear end end, threadedly connected to the rear end of the cylindrical body, the rear end end having a through hole for the flexible shaft to pass through, the flexible shaft passing through the through hole and being driven to the rear end of the rotating shaft; and the outer wall of the rear end end being connected to the rat-track extruder via steel strand.

[0015] Preferably, an impact cavity is formed within the end head, and an impact seat is fixedly disposed within the impact cavity. The front end of the rotating shaft extends into the impact cavity and its diameter increases to form an impact block. An impact column is also disposed within the impact cavity. The impact column can slide axially between the impact block and the impact seat. The rear end of the impact column increases to form an impact-receiving block. The surfaces of the impact-receiving block and the impact block opposite to each other are respectively configured as a first wave surface and a second wave surface that can mesh with each other. A return spring is disposed between the impact-receiving block and the impact seat, and the return spring keeps the impact column always close to the impact block.

[0016] Preferably, the flexible shaft is a steel cable covered with a sheath.

[0017] The present invention has at least the following beneficial effects: First, this invention employs an independent vibrating plowshare structure. Each plowshare contains a rotating shaft and an eccentric block supported by bearings, driven independently by a flexible shaft. This allows the vibration energy to act directly on the plowshare's soil-breaking part, avoiding energy dispersion and loss caused by the frame's involvement in vibration in traditional integral vibration methods. Simultaneously, the plowshare is elastically suspended from the frame via a leaf spring assembly, effectively isolating the vibration from transmission to the frame and traction vehicle, significantly improving driving comfort and reducing the risk of fatigue damage to the traction vehicle.

[0018] Secondly, the present invention sets two leaf spring assemblies spaced apart in the suspension shock absorption assembly, and forms a connecting rod assembly through a triangular hanger bracket and a force transmission link, so that the deformation of the two leaf spring assemblies is coupled with each other to achieve load balance and posture stability. This structure, in conjunction with the plow handle and the diagonal support, significantly enhances the torsional resistance of the plow head during operation, ensures that the mouse track is straight and consistent in depth, and at the same time extends the service life of the leaf spring assembly and reduces maintenance costs.

[0019] Third, this invention features an impact chamber within the plowshare's end head. Inside the chamber, an impact seat, impact block, impact column, and intermeshing wave-like structure, along with a return spring, constitute the impact mechanism. This mechanism converts the rotational motion of the shaft into axial high-frequency impact, creating a combined vibration effect with the radial vibration generated by the eccentric block, significantly improving soil-breaking ability and soil-penetrating efficiency in hard soil. Furthermore, a centrally symmetrical first and second gearbox transmission system allows a single power source to drive multiple plowshares independently, resulting in a compact structure and high transmission efficiency.

It does not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this invention.

[0025] like Figures 1-9 As shown, the present invention provides a composite vibration rat track plow, which includes: A frame 1 is used to connect to a tractor vehicle; a power source 9 is fixedly mounted on the frame 1; at least one suspension shock absorber assembly is mounted on the frame 1; at least one plowshare 3 has its upper end connected to the suspension shock absorber assembly and its lower end connected to a plow head 5, which is a cylindrical structure with a receiving cavity 500 inside. A rotating shaft 54 ​​is rotatably supported in the receiving cavity 500 via a bearing 523, and an eccentric block 541 is provided on the shaft of the rotating shaft 54; a flexible shaft 6 corresponding to each plow head 5, with its first end drivenly connected to the rear end of the rotating shaft 54 ​​and its second end connected to the power source 9, and the shaft of the flexible shaft 6 located at the rear of the plowshare 3; and a rat-path extruder 8, which is flexibly connected to the rear of the plow head 5.

[0026] The frame 1 serves as the load-bearing foundation of this invention and is used for connection to a tractor vehicle. The frame 1 can be constructed from welded steel sections, such as rectangular steel pipes or channel steel, to form a rectangular frame structure, ensuring overall rigidity. The front of the frame 1 is provided with a mounting point 11 for connection to the tractor vehicle; specifically, a standard three-point suspension connection structure can be used for connection to tractors or other tractor vehicles. The upper part of the frame 1 is provided with a mounting base for installing the power source 9, and the lower part of the frame 1 is provided with mounting positions for installing suspension and shock absorber components.

[0027] Power source 9 is fixedly mounted on frame 1. Power source 9 provides rotational power and can be either an electric motor or a hydraulic motor. If an electric motor is used, it is bolted to a motor mounting bracket on frame 1, with the motor's output shaft facing rearward or sideways for connection to flexible shaft 6. If a hydraulic motor is used, it is connected to the hydraulic system of the traction vehicle via hydraulic lines, and the motor housing is bolted to frame 1. The output end of power source 9 has an interface for connecting to flexible shaft 6, which can be keyed or splined for transmission connection to the second end of flexible shaft 6.

[0028] The suspension damping assembly is mounted on the frame 1 and is used to flexibly suspend the plow handle 3. There is at least one suspension damping assembly, but multiple assemblies can be installed depending on the working width; for example, 2-4 suspension damping assemblies can be arranged side-by-side along the width of the frame 1. Each suspension damping assembly is used to connect to one plow handle 3. The specific structure of the suspension damping assembly can employ a leaf spring assembly or a coil spring assembly to achieve flexible suspension.

[0029] The plow handle 3 is a rod-shaped structure, with its upper end connected to the suspension damping assembly and its lower end extending downwards to connect to a plow head 5. The plow handle 3 can be made of steel with a rectangular or circular cross-section to ensure sufficient strength and rigidity. The upper end of the plow handle 3 has a connection structure for connecting to the suspension damping assembly, such as a connecting plate, connecting lug, or hinge hole. The lower end of the plow handle 3 has an interface for connecting to the plow head 5, such as a flange or welding seat, for securing the plow head 5. The rear of the plow handle 3 has a space or guide structure for accommodating a flexible shaft 6, ensuring that the flexible shaft 6 extends along the rear of the plow handle 3.

[0030] The plowshare 5 has a cylindrical structure and is fixedly connected to the lower end of the plow handle 3. The plowshare 5 can be made of high-strength steel, and its front end can be equipped with a cutting edge to reduce soil penetration resistance. A receiving cavity 500 is provided inside the plowshare 5 to accommodate components such as the rotating shaft 54 ​​and the eccentric block 541. The receiving cavity 500 is a cylindrical cavity extending along the axial direction of the plowshare 5, and its diameter is determined according to the dimensions of the rotating shaft 54 ​​and the eccentric block 541. End caps can be provided at the front and rear ends of the receiving cavity 500 or it can be connected to other components. A rotating shaft 54 ​​is rotatably supported inside the receiving cavity 500 by bearings 523. At least two bearings 523 are provided, located at the front and rear ends of the rotating shaft 54 ​​respectively, to ensure the stability of the rotating shaft 54's rotation. The bearings 523 can be rolling bearings, such as deep groove ball bearings or tapered roller bearings, with their outer rings fixedly connected to the inner wall of the receiving cavity 500 and their inner rings fixedly connected to the shaft body of the rotating shaft 54. The rotating shaft 54 ​​is a slender shaft made of high-strength alloy steel, and steps or shoulders can be provided at its front and rear ends for axial positioning. An eccentric block 541 is fixedly mounted on the shaft body of the rotating shaft 54. The eccentric block 541 is a fan-shaped or semi-circular block, which is fixed to the rotating shaft 54 ​​by bolts or welding. It rotates with the rotating shaft 54 ​​to generate centrifugal force, thereby creating vibration. The mass and eccentricity of the eccentric block 541 are determined according to the required vibration force.

[0031] A flexible shaft 6, corresponding to the plowshare 5, is used to transmit power. The first end of the flexible shaft 6 is driven to the rear end of the rotating shaft 54, and the connection can be achieved via a key, pin, or coupling. The second end of the flexible shaft 6 is connected to the power source 9. The shaft body of the flexible shaft 6 is located at the rear of the plowshare 3 and extends along the length of the plowshare 3. The flexible shaft 6 can be a standard flexible shaft assembly, with an internal core made of multiple strands of steel wire wound together, and an external sheath 61 to protect the core and contain lubricant. The flexible shaft 6 has good flexibility, allowing it to transmit rotational motion even when bent, adapting to the relative movement of the plowshare 3 during operation.

[0032] The rat-path extruder 8 is flexibly connected to the rear of the plowshare 5. The rat-path extruder 8 is a bullet-shaped, enlarged-hole body, with a rear diameter larger than its front diameter, used to compress the soil into rat-paths after the plowshare 5 breaks through the soil. The connection between the rat-path extruder 8 and the rear of the plowshare 5 is flexible, specifically using a steel strand 81 or a chain. One end of the steel strand 81 is fixedly connected to the rear end 53 of the plowshare 5, and the other end is fixedly connected to the front end of the rat-path extruder 8. This flexible connection allows the rat-path extruder 8 to deflect slightly when encountering stones or hard objects, preventing jamming or damage.

[0033] During operation, the tractor unit moves the frame 1 forward, and the suspension shock absorber suspends the plow handle 3 and plow head 5 below the frame 1. After the power source 9 starts, it drives the rotating shaft 54 ​​to rotate via the flexible shaft 6. The eccentric block 541 on the rotating shaft 54 ​​rotates, generating centrifugal force, causing the plow head 5 to vibrate. This vibration is transmitted to the soil through the plow head 5, reducing soil resistance and assisting the plow head 5 in breaking through the soil. After the plow head 5 breaks through the soil, the rear rat-track extruder 8 compresses the soil, forming a smooth and compact rat track. The suspension shock absorber assemblies provide elastic support and vibration isolation during operation, minimizing the transmission of plow head 5 vibration to the frame 1 and the tractor unit. The flexible shaft 6 extends along the rear of the plow handle 3, avoiding direct contact between the plow handle 3 and the soil, thus reducing wear.

[0034] In another technical solution, the suspension shock absorber assembly includes a distribution beam 2 and a leaf spring assembly 4. The beam body of the distribution beam 2 is mounted on the frame 1, and the leaf spring assembly 4 is mounted on the distribution beam 2. The upper end of the plow handle 3 is connected to the leaf spring assembly 4. The distribution beam 2 is a long strip beam structure, which can be made of rectangular steel pipe or channel steel. Its beam body is fixed to the lower part of the frame 1 by bolts or welding. The distribution beam 2 extends along the width direction of the frame 1 to provide a mounting base for the leaf spring assembly 4. Mounting seats or connecting lugs for mounting the leaf spring assembly 4 are provided at both ends or in the middle of the distribution beam 2. The leaf spring assembly 4 is mounted on the distribution beam 2. The leaf spring assembly 4 can be made of multiple steel leaf springs of equal or unequal length stacked together. Lubricating gaskets can be provided between the steel plates to reduce friction. The middle part or one end of the leaf spring assembly 4 is fixed to the distribution beam 2 by bolts, center bolts, or U-bolts. The two ends of the leaf spring assembly 4 are free ends or are provided with lugs. The upper end of the plow handle 3 is connected to the leaf spring assembly 4. The specific connection position can be selected according to the stress conditions, such as connecting it to the middle or one end of the leaf spring assembly 4. The upper end of the plow handle 3 is provided with a connecting plate 32 or a connecting lug, which is fixedly connected to the plate body of the leaf spring assembly 4 by bolts, pins, or U-bolts. This suspension shock absorption assembly has a simple structure, utilizing the elastic deformation of the leaf spring to achieve elastic suspension of the plow handle 3, while also playing a role in vibration isolation. The setting of the distribution beam 2 allows multiple leaf spring assemblies 4 to be arranged side by side on the frame 1, facilitating multi-plow operation. The stiffness of the leaf spring assembly 4 can be selected according to the required suspension characteristics and vibration isolation effect, for example, by adjusting the number of leaf springs, length, and thickness to obtain different elastic characteristics.

[0035] In another technical solution, each of the suspension shock absorption components includes two leaf spring assemblies 4 spaced apart front to back. The leaf spring assembly 4 located in front is connected to the upper end of the plow handle 3, and the leaf spring assembly 4 located in the rear is connected to an inclined support 31. The upper end of the inclined support 31 is connected to the leaf spring assembly 4 located in the rear, and the lower end of the inclined support 31 is connected to the plow head 5.

[0036] Each suspension damping assembly includes two leaf spring assemblies 4 spaced apart front to back. The two leaf spring assemblies 4 are arranged parallel to each other along the front-rear direction of the frame 1, with an appropriate gap between them to accommodate subsequent linkage mechanisms or other connecting components. The front leaf spring assembly 4 is connected to the upper end of the plow handle 3, specifically by using a connecting plate 32 and U-bolts 34 for fastening, so that the plow handle 3 is suspended below the front leaf spring assembly 4. The rear leaf spring assembly 4 is connected to an inclined support 31, which is an inclined rod-like structure and can be made of steel pipe or shaped steel. The upper end of the inclined support 31 is connected to the rear leaf spring assembly 4, also using a connecting plate 32 and U-bolts 34 for fastening, so that the inclined support 31 is suspended below the rear leaf spring assembly 4. The lower end of the inclined support 31 extends rearward and downward and connects to the plow head 5, specifically by welding or bolting, so that the inclined support 31 provides auxiliary support to the plow head 5. This double-leaf spring and diagonal support structure allows the plowshare 5 to be constrained simultaneously by the front plow handle 3 and the rear diagonal support 31, forming a stable triangular support structure. The front leaf spring assembly 4 mainly bears the vertical load and vibration, while the rear leaf spring assembly 4 applies a diagonal support force to the plowshare 5 through the diagonal support 31, effectively resisting the lateral force and torsional moment experienced by the plowshare 5 during operation and maintaining the stability of the plowshare 5's posture. Simultaneously, the elastic deformation of the two leaf spring assemblies 4 works in tandem, allowing the plowshare 5 to adaptively adjust when encountering soil of uneven hardness, reducing jamming and deflection. The connection point between the lower end of the diagonal support 31 and the plowshare 5 is located near or slightly rear of the plowshare 5's center of gravity for optimal support. The stiffness of the two leaf spring assemblies 4 can be selected to be the same or different specifications according to actual needs; for example, the front leaf spring assembly 4 can use greater stiffness to bear the main load, while the rear leaf spring assembly 4 can use less stiffness to provide auxiliary support.

[0037] In another technical solution, a connecting plate 32 is provided at the upper end of the inclined support 31 and the upper end of the plow handle 3. The connecting plate 32 is in contact with the lowermost plate of the corresponding leaf spring assembly 4. A limiting block 33 is provided above the uppermost plate of each leaf spring assembly 4. The connecting plate 32 and the corresponding limiting block 33 are fastened together by at least one U-bolt 34. The arc-shaped bend of the U-bolt 34 is wrapped around the limiting block 33 and the leaf spring assembly 4. After the threaded part of the U-bolt 34 passes through the connecting plate 32, the connecting plate 32, the leaf spring assembly 4 and the limiting block 33 are clamped and fixed by a nut.

[0038] A connecting plate 32 is respectively provided at the upper end of the inclined support 31 and the upper end of the plow handle 3. The connecting plate 32 is a flat plate structure, which can be made by cutting steel plate, and its lower surface is in contact with the lowermost plate of the corresponding leaf spring assembly 4. The connecting plate 32 has through holes for the threaded part of the U-bolt 34 to pass through, and the position and number of through holes correspond to the threaded part of the U-bolt 34. A limiting block 33 is provided above the uppermost plate of each leaf spring assembly 4. The limiting block 33 is a block structure, which can be made of steel plate or cast steel. The lower surface of the limiting block 33 is in contact with the uppermost plate of the leaf spring assembly 4, and the limiting block 33 has through holes for the threaded part of the U-bolt 34 to pass through. The function of the limiting block 33 is to provide an upper clamping point when the U-bolt 34 is tightened, and at the same time limit the excessive deformation of the leaf spring assembly 4.

[0039] The connecting plate 32 and the corresponding limiting block 33 are fastened together by at least one U-bolt 34. The U-bolt 34 is a bolt bent into a U-shape, having an arc-shaped bend and threaded portions extending from both ends of the arc-shaped bend. The arc-shaped bend wraps around the outside of the limiting block 33 and the leaf spring assembly 4, so that the leaf spring assembly 4 and the limiting block 33 are contained between the arc-shaped bend and the connecting plate 32. The threaded portions extend downwards, pass through a through hole in the connecting plate 32, and are then tightened by a nut. The nut cooperates with the threaded portion 34 to clamp and fix the connecting plate 32, the leaf spring assembly 4, and the limiting block 33 together.

[0040] This fastening connection method ensures that the connecting plate 32 fits tightly against the lowest plate of the leaf spring assembly 4, and the limiting block 33 fits tightly against the uppermost plate of the leaf spring assembly 4. The arc-shaped bend of the U-bolt 34 embraces the entire leaf spring assembly 4 and the limiting block 33 from above, while the screw pulls the connecting plate 32 and the limiting block 33 from above, thus firmly clamping the entire leaf spring assembly 4 between the connecting plate 32 and the limiting block 33. This structure avoids drilling holes in the leaf spring assembly 4, maintains the overall strength of the leaf spring assembly 4, and allows the leaf spring assembly 4 to undergo normal elastic deformation under stress. The limiting block 33 also limits the maximum deformation of the leaf spring assembly 4, preventing damage due to excessive deformation. The number of U-bolts 34 can be determined according to the width of the leaf spring assembly 4 and the required clamping force; typically, two or three are arranged at intervals along the length of the leaf spring assembly 4. Washers can be placed between the nut and the connecting plate 32 to increase the contact area and prevent loosening.

[0041] In another technical solution, at least one constraint ring 7 is spaced apart along the length of the rear part of the inclined support 31, and the shaft of the flexible shaft 6 passes through the constraint ring 7 in sequence. The constraint ring 7 is a ring or semi-ring structure and can be made by bending metal tubing or sheet metal. The inner diameter of the constraint ring 7 is clearance-fitted with the outer diameter of the flexible shaft 6 to allow the flexible shaft 6 to pass through smoothly. Connecting lugs or welding seats are provided on the outer side of the constraint ring 7, which are fixed to the rear part of the inclined support 31 by bolts or welding. The number of constraint rings 7 can be determined according to the length of the inclined support 31 and the required degree of constraint for the flexible shaft 6; for example, 2-4 constraint rings 7 can be evenly spaced along the length of the inclined support 31.

[0042] The shaft of the flexible shaft 6 is sequentially threaded through the constraint rings 7. After being led out from the power source 9, the flexible shaft 6 first passes through the upper constraint ring 7, then sequentially through each of the lower constraint rings 7, and finally connects to the rotating shaft 54 ​​inside the plow head 5. The constraint rings 7 guide and constrain the flexible shaft 6, ensuring that the shaft extends close to the rear of the inclined support 31, preventing the flexible shaft 6 from swinging, tangling, or interfering with surrounding components due to vibration during operation. Simultaneously, the constraint rings 7 limit the bending radius of the flexible shaft 6, preventing excessive bending that could lead to fatigue fracture of the internal steel wires. The inner wall of the constraint rings 7 can be lined with lubricating material or wear-resistant bushings to reduce friction with the sheath 61 of the flexible shaft 6. The spacing between adjacent constraint rings 7 is determined based on the stiffness of the flexible shaft 6 and the allowable overhang length, typically 200-500 mm, ensuring that the sag of the flexible shaft 6 between any two points is controlled within the allowable range. The arrangement of this constraint ring 7 ensures that the flexible shaft 6 maintains a stable posture as it follows the movement of the plow handle 3 and the inclined support 31, which not only guarantees the reliability of power transmission but also extends the service life of the flexible shaft 6.

[0043] In another technical solution, the distribution beam 2 includes two C-shaped steel sections 21 arranged opposite to each other. The leaf spring assembly 4 is installed between the two C-shaped steel sections 21. The front lugs 401 of the two leaf spring assemblies 4 are installed between the two C-shaped steel sections 21 through hinge supports 41. A connecting rod assembly is connected between the rear lugs 402 of the two leaf spring assemblies 4. The connecting rod assembly includes two triangular lifting lug brackets 42 and a force transmission connecting rod 43. The triangular lifting lug brackets 42 have a first hinge portion 421, a second hinge portion 422 and a third hinge portion 423 distributed in a triangular pattern. The first hinge portion 421 is rotatably installed between the two C-shaped steel sections 21. The second hinge portion 422 is rotatably connected to the corresponding rear lug 402. The two ends of the force transmission connecting rod 43 are rotatably connected to the third hinge portion 423 of the two triangular lifting lug brackets 42 respectively.

[0044] C-shaped steel section 21 is a cold-formed steel section with a C-shaped cross-section, possessing high bending strength. The openings of the two C-shaped steel sections 21 are arranged opposite to each other, with one opening to the left and the other to the right. They are arranged parallel to each other and fixed together by welding or bolts to form a composite beam structure. An installation space is formed between the two C-shaped steel sections 21 for installing the leaf spring assembly 4 and other connecting components. This structure ensures the overall strength of the distribution beam 2 while providing convenient installation space.

[0045] Two leaf spring assemblies 4 are spaced apart on the distribution beam 2 along the front-to-back direction. Each leaf spring assembly 4 has a front lug 401 at its front end and a rear lug 402 at its rear end. Both the front lug 401 and the rear lug 402 are annular structures, which can be formed at the ends of the leaf springs through a rolling process, for hinged connection with other components. The front lugs 401 of the two leaf spring assemblies 4 are mounted between two C-shaped steel sections 21 via hinge supports 41. The hinge supports 41 are block-shaped or plate-shaped structures, with both ends fixedly connected to the inner walls of the two C-shaped steel sections 21, for example, by welding or bolting. The hinge supports 41 are provided with pin holes, and the front lugs 401 are rotatably mounted on the hinge supports 41 via pins, allowing the front end of the leaf spring assembly 4 to swing up and down around the pin.

[0046] A connecting rod assembly connects the rear lugs 402 of the two leaf spring assemblies 4. The connecting rod assembly includes two triangular lug supports 42 and a force transmission link 43. The triangular lug supports 42 are triangular plate structures, which can be machined from steel plates. They have three corners arranged in a triangle, forming a first hinge 421, a second hinge 422, and a third hinge 423, respectively. Each hinge has a pin hole for hinged connection with other components. The first hinge 421 is rotatably mounted between two C-shaped steel sections 21, specifically connected via a pin to a support fixed inside the C-shaped steel section 21 or directly to the web of the C-shaped steel section 21. The second hinge 422 is rotatably connected to the corresponding rear lug 402 via a pin. The third hinge 423 is used to connect the force transmission link 43.

[0047] The force transmission link 43 is a rod-shaped structure, which can be made of steel pipe or solid steel bar. Both ends are provided with connecting lugs or can be directly machined into a flat shape with pin holes. The two ends of the force transmission link 43 are rotatably connected to the third hinge portion 423 of the two triangular lifting lug supports 42 via pins. In this way, the two triangular lifting lug supports 42 are connected as a whole through the force transmission link 43, forming a four-bar linkage.

[0048] The working principle of this linkage assembly is as follows: When one of the leaf spring assemblies 4 is impacted and compressed, its rear lug 402 swings upward, causing the triangular hanger bracket 42 connected to it to rotate around the first hinge 421. The rotation of the triangular hanger bracket 42 is transmitted to the force transmission link 43 through the third hinge 423. The force transmission link 43 transmits the motion to the other triangular hanger bracket 42, forcing the rear lug 402 of the other leaf spring assembly 4 to swing synchronously, thereby coupling and coordinating the deformation of the two leaf spring assemblies 4. This structure allows the two leaf spring assemblies 4 to deform collaboratively under force, resulting in a more uniform load distribution and preventing excessive stress on a single leaf spring assembly 4. At the same time, this linkage mechanism also plays an anti-torsional role. When the plowshare 5 is subjected to lateral force, the two leaf spring assemblies 4 support each other through the linkage assembly, effectively resisting the torsional torque and maintaining the stability of the plowshare 5. The arrangement and angle of the three hinges of the triangular lug bracket 42 can be optimized according to the required motion characteristics and force conditions, such as adjusting the relative distance between each hinge point to obtain the best synergistic effect.

[0049] In another technical solution, a plurality of plow handles 3 are arranged side by side along the width direction of the frame 1. A first gearbox 91 and a plurality of second gearboxes 92 are fixedly mounted on the frame 1. The first gearbox 91 is located in the middle of the plurality of second gearboxes 92. The first gearbox 91 has two power output ends connected to drive shafts 93. The two drive shafts 93 extend in the arrangement direction of the plow handles 3 on both sides. The power input end of each second gearbox 92 is connected to the drive shaft 93. The power output end of each second gearbox 92 is connected to the second end of the corresponding flexible shaft 6. The power input end of the first gearbox 91 is connected to the power source 9.

[0050] A first gearbox 91 and several second gearboxes 92 are fixedly mounted on the frame 1. Both the first gearbox 91 and the second gearboxes 92 are reduction or speed-up gear transmission devices, and power distribution and transmission are achieved internally through gear pairs. The first gearbox 91 is located in the middle of the several second gearboxes 92, that is, centrally arranged along the width direction of the frame 1. The housing of the first gearbox 91 is fixed to the frame 1 with bolts, and its power input end faces the power source 9, and is drively connected to the output end of the power source 9. The first gearbox 91 has two power output ends, facing the left and right sides of the frame 1 respectively, and each power output end is connected to a drive shaft 93.

[0051] Two drive shafts 93 extend in the direction of the plowshares 3 on both sides. Specifically, the left drive shaft 93 extends to the left along the frame 1, passing through the second gearboxes 92 located on the left; the right drive shaft 93 extends to the right along the frame 1, passing through the second gearboxes 92 located on the right. The drive shafts 93 are slender shafts, made of high-strength alloy steel, and their ends are rotatably supported on the frame 1 by drive shaft bearings 95. The drive shaft bearings 95 are fixedly mounted on the frame 1 and contain bearings to support the drive shafts 93 and allow them to rotate freely. The number of drive shaft bearings 95 is determined by the length of the drive shaft 93; typically, one bearing is provided at each end of each drive shaft 93. If the drive shaft 93 is long, one or more drive shaft bearings 95 can be added in the middle to improve support rigidity.

[0052] The power input end of each second gearbox 92 is connected to the drive shaft 93. The housing of the second gearbox 92 is fixed to the frame 1 by a gearbox bracket 94. The gearbox bracket 94 is a metal component, which can be welded or cast from steel plates. Its lower end is fixedly connected to the frame 1, and its upper end is fixedly connected to the housing of the second gearbox 92, for example, by bolts. The height of the gearbox bracket 94 is determined according to the position of the drive shaft 93 to ensure that the power input end of the second gearbox 92 is accurately aligned with the drive shaft 93. The power input end of the second gearbox 92 is provided with an input gear or sprocket, which meshes with the corresponding output gear or sprocket on the drive shaft 93, or is directly connected to the drive shaft 93 by a key connection to realize power transmission. The power output end of each second gearbox 92 is connected to the second end of the corresponding flexible shaft 6. The second end of the flexible shaft 6 is connected to the output shaft of the second gearbox 92 by a coupling or key connection.

[0053] The power input end of the first gearbox 91 is connected to the power source 9. After the power source 9 is started, power is input to the first gearbox 91, and after being distributed by the gears inside the first gearbox 91, it is output to the drive shafts 93 on the left and right sides respectively through the two power output ends. When the drive shafts 93 rotate, they drive the second gearboxes 92 arranged along the line to work. Each second gearbox 92 then transmits power to the rotating shaft 54 ​​in its corresponding plowshare 5 through the corresponding flexible shaft 6, driving the eccentric block 541 to rotate and generate vibration.

[0054] This centrally symmetrical transmission layout has the following advantages: the first gearbox 91 is centrally located, ensuring that the transmission path lengths on both sides are equal, resulting in balanced power distribution and avoiding power loss and phase difference caused by long-distance transmission; the transmission shaft 93 extends along the frame 1, making the structure compact and facilitating the side-by-side arrangement of multiple second gearboxes 92; each second gearbox 92 independently drives a flexible shaft 6, allowing the vibration frequency and amplitude of each plowshare 5 to be independently adjusted to adapt to the operational needs under different soil conditions; the gearbox bracket 94 and the transmission shaft seat 95 ensure the stability and reliability of the transmission system, reducing vibration and noise.

[0055] In another technical solution, the plow head 5 includes: a cylindrical body 52, which is cylindrical in shape and whose outer wall is fixedly connected to the lower end of the plow handle 3. The inner wall of the cylindrical body 52 is provided with a first support 521 and a second support 522 spaced apart along the axial direction. Each of the first support 521 and the second support 522 is provided with a bearing 523. The inner ring of the bearing 523 is used to support the rotating shaft 54. The eccentric block 541 is located between the first support 521 and the second support 522. An end head 51 is threadedly connected to the front end of the cylindrical body 52. ​​A rear end head 53 is threadedly connected to the rear end of the cylindrical body 52. ​​The rear end head 53 has a through hole for the flexible shaft 6 to pass through. After the flexible shaft 6 passes through the through hole, it is driven to connect with the rear end of the rotating shaft 54. The outer wall of the rear end head 53 is connected to the rat-track extruder 8 through a steel strand 81.

[0056] In another technical solution, the plowshare 5 includes a cylindrical body 52, an end head 51, and a rear end 53. The cylindrical body 52 is a cylindrical structure made of high-strength seamless steel pipe or machined cylinder, and its outer wall is fixedly connected to the lower end of the plow handle 3. The connection method can be welding or flange bolt connection. The inner wall of the cylindrical body 52 is axially spaced with a first support 521 and a second support 522. Both the first support 521 and the second support 522 are annular bosses or independently machined annular components, which can be fixed to the inner wall of the cylindrical body 52 by welding. The distance between the first support 521 and the second support 522 is determined according to the length of the rotating shaft 54 ​​and the size of the eccentric block 541. The space between them is used to accommodate the eccentric block 541. Each of the first support 521 and the second support 522 is provided with a bearing 523. The outer ring of the bearing 523 is tightly fitted and fixed with the inner hole of the corresponding support, for example, by transition fit or interference fit, and can be axially positioned by a retaining ring through the hole. The inner ring of bearing 523 supports the rotating shaft 54. The rotating shaft 54 ​​passes through the inner holes of the two bearings 523 and fits tightly with the inner ring, for example, by using an transition fit and providing a shoulder for axial positioning. An eccentric block 541 is fixedly mounted on the shaft body of the rotating shaft 54 ​​and located between the first support 521 and the second support 522. The eccentric block 541 can be fixed to the rotating shaft 54 ​​by key connection, pin connection, or welding. This double-support, double-bearing support structure ensures good stability and concentricity of the rotating shaft 54 ​​during high-speed rotation. The vibration force generated by the eccentric block 541 is evenly transmitted to the cylinder body 52 through the bearings 523, and then to the soil.

[0057] The end head 51 is threaded to the front end of the cylinder body 52. ​​The end head 51 is tapered or bullet-shaped with a sharp front end to reduce soil penetration resistance. The rear end of the end head 51 has external threads that engage with the internal threads at the front end of the cylinder body 52. ​​This threaded connection facilitates disassembly and replacement of the end head 51. When the end head 51 wears down, it is not necessary to replace the entire plowshare 5; simply unscrew the old end head 51 and replace it with a new one, reducing maintenance costs. A sealing gasket can be installed between the end head 51 and the cylinder body 52 to prevent mud and sand from entering the receiving cavity 500.

[0058] The rear end portion 53 is threaded to the rear end of the cylinder body 52. ​​The rear end portion 53 is cylindrical or disc-shaped, with an external thread at its front end that engages with the internal thread at the rear end of the cylinder body 52. ​​This threaded connection facilitates disassembly; when the shaft 54, bearing 523, or eccentric block 541 needs maintenance or replacement, simply unscrewing the rear end portion 53 opens the receiving cavity 500 without disassembling the entire plowshare 5. The rear end portion 53 has a through hole for the flexible shaft 6 to pass through, the position of which corresponds to the rear end of the shaft 54. The flexible shaft 6 passes through the through hole and drives into the rear end of the shaft 54; this connection can be achieved using a key, pin, or coupling. A sealing ring or wear-resistant bushing can be installed inside the through hole to prevent sand and dirt from entering and reduce wear on the flexible shaft 6. The outer wall of the rear end portion 53 is connected to the rat-track extruder 8 via a steel strand 81. The steel strand 81 is a flexible rope made of multiple strands of steel wire twisted together. One end is fixedly connected to the outer wall of the rear end 53, for example, by a connecting lug fixed by welding or bolts, and the other end is fixedly connected to the front end of the rat tunnel extruder 8. The length of the steel strand 81 is determined according to the required connection distance, and usually leaves an appropriate margin so that the rat tunnel extruder 8 can swing freely within a certain range. This flexible connection method allows the rat tunnel extruder 8 to automatically deflect when encountering stones or hard objects, avoiding jamming or damage, while transmitting traction force so that the rat tunnel extruder 8 follows the plow head 5 forward and compresses and shapes the soil.

[0059] In another technical solution, an impact cavity 501 is formed within the end head 51, and an impact seat 511 is fixedly disposed within the impact cavity 501. The front end of the rotating shaft 54 ​​extends into the impact cavity 501 and its diameter increases to form an impact block 542. An impact column 512 is also disposed within the impact cavity 501. The impact column 512 can slide axially between the impact block 542 and the impact seat 511. The rear end of the impact column 512 is enlarged to form an impact-receiving block 5121. The surfaces of the impact-receiving block 5121 and the impact block 542 opposite to each other are respectively configured as a first wave surface 5120 and a second wave surface 5420 that can mesh with each other. A return spring 513 is disposed between the impact-receiving block 5121 and the impact seat 511. The return spring 513 keeps the impact column 512 always close to the impact block 542.

[0060] The impact cavity 501 is a cylindrical cavity extending axially inside the end head 51, with a diameter larger than that of the rotating shaft 54, used to accommodate the relevant components of the impact mechanism. The rear end of the impact cavity 501 is connected to the receiving cavity 500, allowing the rotating shaft 54 ​​to extend into the receiving cavity 500 from front to back. An impact seat 511 is fixedly installed inside the impact cavity 501. The impact seat 511 has an annular or disc-shaped structure, which can be made of high-strength steel, and its outer wall is fixedly connected to the inner wall of the impact cavity 501, for example, by welding or threaded connection. The impact seat 511 is located at the front of the impact cavity 501, and has a through hole in its middle for the subsequent impact pin 512 to pass through or avoid.

[0061] The front end of the rotating shaft 54 ​​extends into the impact cavity 501, and the diameter of this front end is increased to form an impact block 542. The impact block 542 has a disc-shaped or cylindrical structure and is integrally formed with the rotating shaft 54 ​​or fixed to the front end of the rotating shaft 54 ​​by welding or keying. The diameter of the impact block 542 is larger than the diameter of the rotating shaft 54 ​​and smaller than the inner diameter of the impact cavity 501, allowing it to rotate freely within the impact cavity 501. The rear end face of the impact block 542 (i.e., the side facing the impact post 512) is set as a second wave surface 5420.

[0062] An impact column 512 is also provided inside the impact cavity 501. The impact column 512 is a cylindrical rod-shaped structure with an outer diameter slightly smaller than the inner diameter of the impact cavity 501, allowing it to slide freely axially within the impact cavity 501. The impact column 512 is located between the impact block 542 and the impact seat 511, with its rear end (i.e., the end closer to the impact block 542) having an increased diameter to form the impact receiving block 5121. The impact receiving block 5121 is a disc-shaped structure, integrally formed or fixedly connected to the impact column 512. The front end face of the impact receiving block 5121 (i.e., the side facing the impact block 542) is set as a first wave surface 5120. The first wave surface 5120 and the second wave surface 5420 are arranged opposite each other, and their surfaces are set as interlocking wave-shaped curved surfaces. The crests and troughs of the wave surface are evenly distributed along the circumferential direction, and their number and shape are determined according to the required impact frequency and stroke, for example, set to 3-6 crests.

[0063] A return spring 513 is provided between the impact block 5121 and the impact seat 511. The return spring 513 is a cylindrical helical compression spring, sleeved on the outside of the impact column 512. The front end of the return spring 513 abuts against the rear end face of the impact block 5121, and the rear end abuts against the front end face of the impact seat 511. The return spring 513 is always in a compressed state, and its elastic force keeps the impact column 512 tending to move closer to the impact block 542, that is, pushing the first wave surface 5120 of the impact block 5121 to press tightly against the second wave surface 5420 of the impact block 542.

[0064] During operation, the rotating shaft 54 ​​rotates under the drive of the flexible shaft 6, causing the impact block 542 and its second wave surface 5420 to rotate together. Due to the elastic force of the return spring 513, the first wave surface 5120 of the impact block 5121 always remains in contact with the second wave surface 5420. When the crest of the second wave surface 5420 aligns with the crest of the first wave surface 5120, the impact block 5121 is pushed forward, and the impact column 512 slides towards the impact seat 511 against the elastic force of the return spring 513. When the crest of the second wave surface 5420 passes and the trough aligns with the crest of the first wave surface 5120, the impact block 5121 quickly rebounds backward under the elastic force of the return spring 513, and the rear end face of the impact column 512 or the rear end face of the impact block 5121 impacts the impact seat 511, generating an axial impact force. For each rotation of the rotating shaft 54, the impact column 512 completes one reciprocating slide and one impact, forming a high-frequency axial impact. The axial impact and the radial vibration generated by the eccentric block 541 work together on the plowshare 5 to create a composite vibration effect, significantly improving the soil-breaking ability in hard soil. The impact surfaces of the impact seat 511 and the impact column 512 can be fitted with a wear-resistant layer or inlaid with wear-resistant materials to extend their service life.

[0065] In another technical solution, the flexible shaft 6 is a steel cable covered with a sheath 61. The inner core of the flexible shaft 6 is a steel cable made of multiple strands of high-strength steel wires twisted together, which has good flexibility and tensile strength, can withstand high-frequency rotational torque, and can stably transmit power under bending conditions. The core of the steel cable can be provided with a central steel wire, and the outer layer is made of multiple layers of steel wires wound in opposite directions. This structure ensures flexibility while having high torsional strength and fatigue life.

[0066] The sheath 61 covers the outside of the steel cable. The sheath 61 can be made of wear-resistant rubber, polyurethane, or nylon, and has good wear resistance, oil resistance, and weather resistance. A lubrication layer, such as grease, can be provided between the sheath 61 and the steel cable to reduce friction between them, thus reducing wear and heat generation. The outer diameter of the sheath 61 is determined according to the application requirements and is usually designed to match the inner diameter of the constraint ring 7, allowing the flexible shaft 6 to slide smoothly within the constraint ring 7 without excessive clearance.

[0067] The flexible shaft 6 has connectors at both ends for connecting to the output end of the power source 9 or the second gearbox 92, as well as the rear end of the rotating shaft 54. The connectors can be made of metal and are fixedly connected to the end of the steel cable by pressing, welding, or casting. The connectors have keyways, pin holes, or splines that mate with the corresponding connection structure on the power output shaft or rotating shaft 54 ​​to transmit torque. The outer wall of the sheath 61 can be provided with a wear-resistant layer or spiral reinforcing ribs to improve its wear resistance and compression resistance. At the position where the flexible shaft 6 passes through the constraint ring 7, the sheath 61 forms a sliding fit with the inner wall of the constraint ring 7. The constraint ring 7 guides and limits the flexible shaft 6, preventing excessive swaying during high-speed rotation. The sheath 61 also prevents mud, water, and corrosive substances from entering the interior of the flexible shaft 6, protecting the steel cable from corrosion and wear, and significantly extending the service life of the flexible shaft 6. When the flexible shaft 6 wears out after prolonged use, only the entire flexible shaft 6 needs to be replaced, making maintenance convenient.
