Description

Technical Field

[0001] This invention relates to the field of agricultural reclamation technology, and in particular to an agricultural reclamation and soil-turning device. Background Technology

[0002] In agricultural tillage and soil-turning devices, the plowshare is typically rigidly fixed to the mounting frame by welding or bolts, forming an integral structure with the frame. This method ensures stable tillage depth in uniformly cultivated land, but when operating on wasteland containing stones, tree roots, or compacted layers, the resistance experienced by the plowshare is abrupt. Instantaneous impact loads are directly transmitted to the plowshare and its connecting parts, lacking a load release path, which can easily lead to plowshare breakage, frame deformation, and power system overload.

[0003] Existing technologies suffer from the problem that rigid connections of soil-turning components lack the ability to allow for clearance, making the device prone to damage when subjected to impact. Summary of the Invention

[0004] In order to overcome the shortcomings of the prior art, the purpose of this invention is to provide an agricultural tillage and soil turning device that enables the tillage components to have the ability to give way, so as to reduce the probability of damage to the device when subjected to impact.

[0005] The objective of this invention is achieved through the following technical solution:

[0006] An agricultural tillage and soil-turning device, comprising:

[0007] The mounting frame is defined as the forward direction of the mounting frame as the first direction;

[0008] A support rod is mounted on the mounting frame, and the extension direction of the support rod is parallel to the vertical plane containing the first direction.

[0009] A guide groove is provided on the support rod and is arranged along the extension direction of the support rod;

[0010] A guide slider is disposed within the guide groove and slides in cooperation with the guide groove;

[0011] A soil-turning component is hinged to the lower part of the support rod, and the extension direction of the support rod is parallel to the plane of the swing path of the soil-turning component. The soil-turning component is used to till the land.

[0012] A connecting rod, one end of which is hinged to the soil-turning component and the other end of which is hinged to the guide slider, the connecting rod being used to transmit the impact force received by the soil-turning component to the guide slider;

[0013] A wedge block is slidably mounted on the support rod and positioned on the sliding path of the guide slider, away from the soil-turning component. The guide slider has a first inclined surface facing the wedge block, and the wedge block has a second inclined surface facing the guide slider. The first and second inclined surfaces slide in contact with each other so that when the guide slider is subjected to force and moves along the guide groove away from the soil-turning component, the first and second inclined surfaces slide in contact with each other to force the wedge block to move away from the support rod.

[0014] An elastic buffer assembly, one end of which is located on the wedge block at the end away from the support rod;

[0015] A linear drive mechanism is provided on the support rod, and the other end of the elastic buffer assembly is provided at the output of the linear drive mechanism. The linear drive mechanism is used to drive the elastic buffer assembly to move along the axial direction of the elastic buffer assembly, so as to adjust the elastic preload of the elastic buffer assembly on the wedge block, and drive the wedge block to press against the guide slider through the inclined surface, so as to restrict the soil turning component from swinging toward the support rod via the connecting rod.

[0016] Further, the elastic buffer assembly includes a first sleeve, a second sleeve, a first elastic element, and a threaded sleeve. One end of the first sleeve is located on the wedge block at the end away from the support rod. One end of the second sleeve is located at the output portion of the linear drive mechanism. The first sleeve is slidably sleeved on the outside of the second sleeve. A limiting portion is provided on the outer wall of the second sleeve, which abuts against the end of the first sleeve near the second sleeve to limit the sliding stroke of the first sleeve relative to the second sleeve. The first elastic element is housed within the first sleeve and the second sleeve, and one end of the first elastic element is connected to the end of the first sleeve near the support rod. The other end of the first elastic element is connected to the end of the second sleeve near the linear drive mechanism; the threaded sleeve is sleeved on the outside of the first sleeve and the second sleeve, and the end of the threaded sleeve near the first sleeve is threadedly connected to the outer wall of the first sleeve. The end of the threaded sleeve near the second sleeve is provided with a limiting ring. The first sleeve, the limiting part, and the limiting ring are arranged sequentially along the extension direction of the first sleeve. The limiting ring is used to abut against the limiting part when the linear drive mechanism drives the elastic buffer assembly away from the support rod, so as to drive the first sleeve to move away from the support rod via the threaded sleeve.

[0017] Furthermore, the agricultural land reclamation and soil turning device also includes a mounting housing, the mounting housing and the outer wall of the support rod together enclosing a mounting cavity, the linear drive mechanism and the elastic buffer assembly are both housed in the mounting cavity, and the linear drive mechanism is mounted on the inner wall of the mounting housing.

[0018] Furthermore, the agricultural tillage and soil-turning device also includes a force sensor, which is mounted on the support rod. The end of the elastic buffer assembly near the support rod is pressed against the force sensor, and the force sensor is used to monitor the initial elastic preload of the elastic buffer assembly.

[0019] Furthermore, the agricultural tillage and soil-turning device further includes a guide beam and an elastic locking assembly. The guide beam is mounted on the mounting frame, and its extension direction is perpendicular to a first direction. The guide beam has an installation channel and a through hole. The installation channel extends through the guide beam along its extension direction, and the through hole connects the installation channel to the external environment along the radial direction of the guide beam. The support rod also has a through sleeve, which is slidably fitted onto the outside of the guide beam. The inner wall of the through sleeve has an arc-shaped groove. The elastic locking assembly is located within the installation channel along the radial direction of the guide beam. The elastic locking assembly has a ball bearing at one end facing the through hole. The ball bearing is rotatably embedded in the end of the elastic locking assembly near the through hole, passing through the through hole and fitting into the arc-shaped groove. The elastic locking assembly applies an elastic force to the ball bearing, causing it to press against the arc-shaped groove, thereby elastically locking the through sleeve onto the guide beam. When the lateral force on the through sleeve exceeds the elastic preload of the elastic locking assembly, the ball bearing overcomes the elastic force and exits the arc-shaped groove. The through sleeve slides along the guide beam, thereby achieving lateral clearance of the support rod and the soil-turning component on it.

[0020] Furthermore, the elastic locking assembly includes a ball bearing, a ball seat, a second elastic element, and a limiting sleeve. The ball bearing is rotatably embedded in the ball seat; the ball seat is slidably disposed within the limiting sleeve; the second elastic element is disposed within the limiting sleeve, one end of the second elastic element is connected to the ball seat, and the other end of the second elastic element is connected to the inner wall of the limiting sleeve; the limiting sleeve is disposed within the mounting channel.

[0021] Furthermore, the agricultural tillage and soil-turning device further includes an adjusting crossbar, which has a threaded adjusting section and a tapered adjusting section, and the adjusting crossbar passes through the installation channel; the ball seat is slidably inserted into the through hole; the threaded adjusting section is threadedly engaged with the inner wall of the installation channel to drive the adjusting crossbar to move axially along the installation channel as a whole when the adjusting crossbar is rotated; a third inclined surface is provided on the limiting sleeve near the tapered adjusting section, and the third inclined surface slides in engagement with the tapered surface of the tapered adjusting section, so that when the tapered adjusting section moves axially, it pushes the limiting sleeve through the third inclined surface, and the limiting sleeve then pushes the ball seat and the ball bearing to move radially along the through hole through the second elastic element, thereby adjusting the clamping force of the ball bearing on the arc-shaped groove.

[0022] Furthermore, the ball seat is also provided with a limiting rod, which is located on one end of the ball seat facing the limiting sleeve. The limiting rod is used to press against the limiting sleeve to prevent the second elastic element from being over-compressed.

[0023] Furthermore, multiple arc-shaped grooves are provided, and the multiple arc-shaped grooves are spaced apart along the axial direction of the through sleeve.

[0024] Furthermore, multiple arc-shaped grooves are provided, and the multiple arc-shaped grooves are spaced apart along the circumference of the through sleeve; multiple through holes are provided, and the multiple through holes are spaced apart along the circumference of the guide beam; multiple elastic locking components are provided, and the multiple elastic locking components are spaced apart along the circumference of the guide beam, and the elastic locking components correspond to and cooperate with the arc-shaped grooves and the through holes one by one.

[0025] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0026] 1. The linear drive mechanism is mounted on the support rod, and the other end of the elastic buffer assembly is located at the output of the linear drive mechanism. The linear drive mechanism drives the elastic buffer assembly to move axially along the elastic buffer assembly, thereby adjusting the elastic preload of the elastic buffer assembly on the wedge block and driving the wedge block to press against the guide slider through the inclined surface. This restricts the swing of the tilling component towards the support rod via the connecting rod. Within the normal tillage resistance range, the inclined surface forms a self-locking clamp, firmly holding the guide slider against the wedge block, preventing it from moving away from the tilling component along the guide groove. This avoids the displacement and shaking of the tilling component due to insufficient spring stiffness during normal operation, resulting in better tillage depth consistency.

[0027] 2. One end of the elastic buffer component is located on the wedge block away from the support rod; the other end is located at the output of the linear drive mechanism. The elastic buffer component absorbs impact energy, converting rigid impact into elastic buffering. When encountering a sudden impact from a hard object during operation, the elastic buffer component can effectively absorb the instantaneous impact energy, transforming the rigid hard impact of the traditional structure into a flexible elastic buffering process. The tilling component can achieve small-amplitude adaptive yielding, avoiding hard impact of the plowshare onto obstacles, effectively reducing the risk of damage to the tilling component. After the impact load is eliminated, the elastic buffer component can release elastic potential energy to assist in structural reset, allowing the tilling component to quickly return to the standard working tilt angle, ensuring the continuity of operation.

[0028] 3. The tilling component is hinged to the lower part of the support rod, and the extension direction of the support rod is parallel to the plane of the swing path of the tilling component. The tilling component is used to till the land. One end of the connecting rod is hinged to the tilling component, and the other end is hinged to the guide slider. The connecting rod is used to transmit the impact force received by the tilling component to the guide slider. A wedge block is slidably inserted through the support rod. The wedge block is located on the sliding path of the guide slider and is located on the side of the guide slider away from the tilling component. The guide slider has a first inclined surface facing the wedge block, and the wedge block has a second inclined surface facing the guide slider. The first and second inclined surfaces slide in engagement so that when the guide slider is subjected to force and moves along the guide groove in a direction away from the tilling component, the first and second inclined surfaces slide in engagement to force the wedge block to move in a direction away from the support rod. When the impact force further exceeds the disengagement limit of the inclined surface engagement, the first and second inclined surfaces slide relative to each other until they disengage, the guide slider moves along the guide groove in a direction away from the tilling component, and the tilling component swings backward to make way. As a result, the soil-turning component achieves maximum clearance travel, completely avoiding obstacles, and the impact load is no longer transmitted to the device, thereby reducing the risk of damage to the device when subjected to impact.

[0029] 4. A linear drive mechanism is used to drive the elastic buffer assembly to move along its axial direction, thereby adjusting the elastic preload of the elastic buffer assembly on the wedge block. By changing the compression of the elastic buffer assembly through the linear drive mechanism, the clamping force of the inclined plane can be adjusted, allowing the same equipment to adapt to various working environments such as sand, clay, and gravel. The protective force can be adjusted without replacing parts, improving the adaptability of the device to different working conditions. Attached Figure Description

[0039] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0040] It should be noted that when an element is described as being "fixed to" another element, it can be directly attached to the other element or there may be an intervening element. When an element is described as being "connected to" another element, it can be directly connected to the other element or there may be an intervening element. The terms "vertical," "horizontal," "left," "right," and similar expressions used herein are for illustrative purposes only and do not represent the only possible implementations.

[0041] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein in the description of the invention is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0042] See Figures 1-8 An agricultural tillage and soil-turning device according to a preferred embodiment of the present invention includes: a mounting frame 1, a support rod 2, a guide chute 3, a guide slider 4, a tillage component 5, a connecting rod 6, a wedge block 7, an elastic buffer assembly 8, and a linear drive mechanism 9.

[0043] The forward direction of the mounting frame 1 is defined as the first direction. This agricultural tillage and soil-turning device uses the mounting frame 1 as its overall supporting foundation. The mounting frame 1 is used to install and support the various working components of the device, and to attach the entire device to a tractor or other traction power equipment. During operation, the device moves continuously along the field surface with the traction power equipment to complete the tillage operation. When the device is operating normally, the direction in which the mounting frame 1 moves forward with the traction power equipment is its forward direction, which is defined as the first direction.

[0044] Support rod 2 is mounted on the mounting frame 1, and its extension direction is parallel to the vertical plane containing the first direction. Support rod 2 serves as the load-bearing and mounting base for the tilling operation component. It is fixedly assembled onto the mounting frame 1 and moves synchronously with it. To ensure that the subsequent swinging and avoidance of the tilling component 5 is within a regular and uniform working plane, and to prevent jamming or force shifting due to spatial misalignment, the extension direction of support rod 2 is parallel to the vertical plane containing the first direction. The support rod 2 can be installed on the mounting frame 1 using direct fixing methods such as welding or bolting, or using hinged or sliding adjustment assembly methods. Rigid fixing ensures the overall structural strength and operational stability of support rod 2, suitable for stable tilling operations on conventional leveled land; while hinged or sliding installation methods allow for fine-tuning of the angle or position of support rod 2.

[0045] A guide groove 3 is provided on the support rod 2, and the guide groove 3 is set along the extension direction of the support rod 2. The guide groove 3 is arranged along the extension direction of the support rod 2 so that the sliding stroke direction of the groove is consistent with the arrangement direction of the support rod 2. This ensures that the force on the components moving along the guide groove 3 on the support rod 2 is transmitted along the extension direction of the groove, thereby constraining the sliding motion trajectory and avoiding lateral deviation. The guide groove 3 can be a T-shaped groove, a V-shaped groove, or an L-shaped groove, etc. Preferably, the guide groove 3 is integrally formed on the support rod 2, but it can also be fixed to the surface of the support rod 2 by means of separate assembly methods such as bolt connection or welding. Among them, the guide groove 3 is integrally formed on the support rod 2, which can reduce the assembly gap, increase the overall structural strength, and make it less prone to deformation and loosening when subjected to impact loads.

[0046] The guide slider 4 is disposed within the guide groove 3 and slides in conjunction with the guide groove 3. The guide slider 4 can be a T-shaped slider, an L-shaped slider, or a rectangular slider, etc., with its shape matching the cross-sectional profile of the guide groove 3. This restricts the lateral displacement of the guide slider 4 relative to the guide groove 3, allowing it to slide linearly only along the extension direction of the guide groove 3. This fit ensures that the guide slider 4 will not dislodge from the guide groove 3 during impact load transmission, maintaining the reliability of the sliding guidance.

[0047] The soil-turning component 5 is hinged to the lower part of the support rod 2. The extension direction of the support rod 2 is parallel to the plane of the swing path of the soil-turning component 5. The soil-turning component 5 is used to till the land. The soil-turning component 5 can be a plowshare, harrow teeth, tillage shovel, etc. The soil-turning component 5 is hinged to the lower part of the support rod 2, and can swing with the hinge position as the swing fulcrum. The extension direction of the support rod 2 is parallel to the plane of the swing path of the soil-turning component 5, which ensures that the swing motion of the soil-turning component 5 is within a preset plane when encountering obstacles, avoiding spatial torsional interference. The soil-turning component 5 cuts into the soil during the device's forward movement, realizing the breaking and tilling of wasteland. Different types of soil-turning components 5 can be selected and adapted according to environmental factors such as soil hardness and stone content.

[0048] One end of the connecting rod 6 is hinged to the soil-turning component 5, and the other end is hinged to the guide slider 4. The connecting rod 6 is used to transmit the impact force received by the soil-turning component 5 to the guide slider 4. When the guide slider 4 is a rectangular slider, the connecting rod 6 should be movably inserted through the guide groove 3 to avoid the groove body structure and ensure that the connecting rod 6 will not interfere with the side wall of the groove when it swings with the soil-turning component 5 and drives the guide slider 4 to slide. As a force-transmitting link, the connecting rod 6 directly transmits the impact load generated by the soil-turning component 5 hitting the obstacle to the guide slider 4, converting the swing displacement of the soil-turning component 5 into the linear sliding displacement of the guide slider 4 along the guide groove 3, providing a force and displacement transmission path for subsequent buffering and yielding actions. Both ends of the connecting rod 6 are hinged, which can adapt to the small changes in the distance between the two hinge points during the swing of the soil-turning component 5, so as to avoid force transmission jamming and thus ensure the smooth transmission of impact load.

[0049] A wedge 7 is slidably mounted on the support rod 2. The wedge 7 is positioned on the sliding path of the guide slider 4, away from the soil-turning component 5. The guide slider 4 has a first inclined surface 401 facing the wedge 7, and the wedge 7 has a second inclined surface 701 facing the guide slider 4. The first inclined surface 401 and the second inclined surface 701 are slidably engaged, so that when the guide slider 4 is subjected to force and moves along the guide groove 3 away from the soil-turning component 5, the first inclined surface 401 and the second inclined surface 701 are slidably engaged, forcing the wedge 7 to move away from the support rod 2. The wedge 7 can slide along the support rod 2 and is positioned at the rear end of the guide slider 4's travel path to receive the impact load transmitted from the guide slider 4. The guide slider 4 and the wedge block 7 rely on a pair of mutually fitting inclined surfaces to achieve force direction transmission. When the soil-turning component 5 encounters an obstacle and is impacted, the guide slider 4 slides backward along the guide groove 3. The first inclined surface 401 slides relative to the second inclined surface 701. Utilizing the wedge-tightening transmission effect of the inclined surfaces, the horizontal thrust of the guide slider 4 along the groove direction is converted into a displacement of the wedge block 7 along the direction perpendicular to the groove, causing the wedge block 7 to move away from the support rod 2. This inclined surface transmission structure can realize the conversion of load direction, transferring the instantaneous impact on the soil-turning component 5 to the subsequent buffer structure, providing a motion basis for the release of impact energy and the longitudinal clearance of the soil-turning component 5.

[0050] One end of the elastic buffer assembly 8 is located on the wedge block 7 at the end away from the support rod 2. The connection between the elastic buffer assembly 8 and the wedge block 7 can be achieved by bolt fastening, flange connection, clamp connection, or welding, etc., to ensure stable transmission of impact load and maintain synchronous feed and retraction. The elastic buffer assembly 8 can be a gas spring assembly, a spring-hydraulic damper, or a wave spring combined with a guide spindle assembly, etc.

[0051] A linear drive mechanism 9 is mounted on the support rod 2. The other end of the elastic buffer assembly 8 is located at the output of the linear drive mechanism 9. The linear drive mechanism 9 drives the elastic buffer assembly 8 to move axially along its axis, adjusting the elastic preload of the elastic buffer assembly 8 on the wedge block 7. It also drives the wedge block 7 to press against the guide slider 4 via an inclined surface, thus restricting the swing of the soil-turning component 5 towards the support rod 2 via the connecting rod 6. The linear drive mechanism 9 can be fixed to the support rod 2 using auxiliary installation structures such as brackets and support plates, along with welding and bolt fastening, to ensure the stability of the linear drive mechanism 9 during operation. The linear drive mechanism 9 can be selected as a linear reciprocating drive mechanism such as an electric push rod, a cylinder, or a hydraulic cylinder. Its output is a telescopic output structure such as the push rod of an electric push rod, the piston of a cylinder, or the piston rod of a hydraulic cylinder, capable of stably outputting axial thrust and displacement along a linear direction. The linear drive mechanism 9 can drive the elastic buffer assembly 8 to adjust its position along its own axis, thereby precisely changing the compression preload of the elastic buffer assembly 8 and controlling the preload elastic force of the wedge block 7. Under the pre-tightening force, the wedge block 7, through the inclined surface cooperation, always presses against the guide slider 4, keeping the guide slider 4 and connecting rod 6 in a limited locked state. This restricts the soil-turning component 5 from swinging towards the support rod 2 under normal tillage operation conditions, ensuring stable tillage depth and connection rigidity during conventional tillage. It is understandable that after the elastic buffer assembly 8 completes its pre-compression assembly, its remaining compression amount needs to be matched with the sliding stroke of the wedge block 7. During assembly, the remaining compression amount of the elastic buffer assembly 8 is controlled to be greater than the sliding stroke of the wedge block 7. When the guide slider 4 is impacted and slides backward, pushing the wedge block 7 to displacement through the inclined surface, the elastic buffer assembly 8 still retains a margin of compression during the entire sliding stroke of the wedge block 7. It will not lock the mechanism due to being compressed to the limit dead point, thus ensuring that the first inclined surface 401 and the second inclined surface 701 can smoothly slide relative to each other to complete the separation and avoid component breakage due to premature locking of the buffer structure preventing the soil-turning component 5 from avoiding obstacles.

[0052] The working principle of this device is as follows: The device moves forward in the first direction along with the traction equipment. Under normal tillage conditions, the linear drive mechanism 9 drives the elastic buffer component 8 to generate pre-compression. The elastic buffer component 8 applies a continuous thrust to the wedge block 7. The wedge block 7 presses against the guide slider 4 with its inclined surface. The guide slider 4 is confined within the guide groove 3 and constrained by the connecting rod 6. The tillage component 5 maintains a fixed posture and cuts into the soil, ensuring stable tillage depth and achieving normal tillage. When the tillage component 5 encounters obstacles such as stones or tree roots and experiences instantaneous impact loads, the impact force is transmitted to the guide slider 4 via the connecting rod 6, pushing the guide slider 4 to slide along the guide groove 3. Through the inclined surface cooperation between the guide slider 4 and the wedge block 7, the elastic buffer component 8 is further compressed, absorbing and buffering the impact energy. Because the parameters have been pre-matched during the assembly stage, the remaining compression of the elastic buffer component 8 is greater than the sliding stroke of the wedge block 7. The elastic buffer component 8 will not reach its compression limit within the complete sliding stroke of the wedge block 7, ensuring that the inclined surface can continue to slide relative to the wedge block and the mechanism will not lock. When the resistance encountered by the soil-turning component 5 exceeds a certain limit, the first inclined surface 401 and the second inclined surface 701 slide relative to each other until they separate, the guide slider 4 continues to slide along the guide groove 3, and the soil-turning component 5 swings backward to complete the complete repositioning.

[0053] After the obstacle passes, the linear drive mechanism 9 actively retracts, causing the elastic buffer component 8 and the wedge block 7 to move back and release the force, thereby releasing the limit on the guide slider 4. The tilling component 5 automatically swings down and resets under its own weight, and pulls the guide slider 4 back to its original position via the connecting rod 6. After the guide slider 4 is reset, the linear drive mechanism 9 extends again to push the wedge block 7, causing the first inclined surface 401 and the second inclined surface 701 to re-fit and tighten, restoring the pre-tightened locking state of the mechanism, and the device returns to stable tilling operation.

[0054] The linear drive mechanism 9 is mounted on the support rod 2, and the other end of the elastic buffer assembly 8 is located at the output of the linear drive mechanism 9. The linear drive mechanism 9 drives the elastic buffer assembly 8 to move axially along the elastic buffer assembly 8, thereby adjusting the elastic preload of the elastic buffer assembly 8 on the wedge block 7 and driving the wedge block 7 to press against the guide slider 4 through the inclined surface, thereby restricting the swing of the tilling component 5 towards the support rod 2 via the connecting rod 6. Within the normal tillage resistance range, the inclined surface forms a self-locking clamp, and the guide slider 4 is firmly held against the wedge block 7, preventing it from moving away from the tilling component 5 along the guide groove 3. This avoids the displacement and shaking of the tilling component 5 due to insufficient spring stiffness during normal operation, resulting in better tillage depth consistency.

[0055] One end of the elastic buffer component 8 is located on the wedge block 7 away from the support rod 2; the other end of the elastic buffer component 8 is located at the output of the linear drive mechanism 9. The elastic buffer component 8 absorbs impact energy, converting rigid impact into elastic buffering. When encountering a sudden impact from a hard object during operation, the elastic buffer component 8 can effectively absorb the instantaneous impact energy, transforming the rigid hard impact of the traditional structure into a flexible elastic buffering process. The tilling component 5 can achieve small-amplitude adaptive yielding, avoiding hard impact of the plowshare onto obstacles, effectively reducing the risk of damage to the tilling component 5. After the impact load is eliminated, the elastic buffer component 8 can release elastic potential energy to assist in structural reset, allowing the tilling component 5 to quickly return to the standard working tilt angle, ensuring the continuity of operation.

[0056] The tilling component 5 is hinged to the lower part of the support rod 2, and the extension direction of the support rod 2 is parallel to the plane of the swing path of the tilling component 5. The tilling component 5 is used to till the land. One end of the connecting rod 6 is hinged to the tilling component 5, and the other end of the connecting rod 6 is hinged to the guide slider 4. The connecting rod 6 is used to transmit the impact force received by the tilling component 5 to the guide slider 4. The wedge block 7 is slidably inserted through the support rod 2. The wedge block 7 is located on the sliding path of the guide slider 4 and is located on the side of the guide slider 4 away from the tilling component 5. The guide slider 4 has a first inclined surface 401 facing the wedge block 7 and a second inclined surface 701 facing the guide slider 4. The first inclined surface 401 and the second inclined surface 701 are slidably engaged so that when the guide slider 4 is subjected to force and moves along the guide groove 3 in a direction away from the tilling component 5, the first inclined surface 401 and the second inclined surface 701 are slidably engaged to force the wedge block 7 to move in a direction away from the support rod 2. When the impact force further exceeds the disengagement limit of the inclined plane engagement, the first inclined plane 401 and the second inclined plane 701 slide relative to each other until they disengage. The guide slider 4 moves away from the soil-turning component 5 along the guide groove 3, and the soil-turning component 5 swings backward to make way. As a result, the soil-turning component 5 obtains its maximum clearance stroke, completely avoids the obstacle, and the impact load is no longer transmitted to the device, thereby reducing the risk of damage to the device when subjected to impact.

[0057] The linear drive mechanism 9 is used to drive the elastic buffer assembly 8 to move along the axial direction of the elastic buffer assembly 8, so as to adjust the elastic preload of the elastic buffer assembly 8 on the wedge block 7. By changing the compression of the elastic buffer assembly 8 through the linear drive mechanism 9, the clamping force of the inclined surface can be adjusted, so that the same equipment can be adapted to various working environments such as sand, clay, and gravel. The protection force can be adjusted without changing parts, which improves the adaptability of the device to working conditions.

[0058] See Figure 2 , Figure 3 and Figure 4Preferably, the elastic buffer assembly 8 includes a first sleeve 801, a second sleeve 802, a first elastic element 803, and a threaded sleeve 804. One end of the first sleeve 801 is located on the wedge block 7 away from the support rod 2. One end of the second sleeve 802 is located at the output of the linear drive mechanism 9. The first sleeve 801 is slidably sleeved on the outside of the second sleeve 802. A limiting part 8021 is provided on the outer wall of the second sleeve 802. The limiting part 8021 is used to abut against the end of the first sleeve 801 near the second sleeve 802 to limit the sliding stroke of the first sleeve 801 relative to the second sleeve 802. The first elastic element 803 is housed within the first sleeve 801 and the second sleeve 802. One end of the first elastic element 803 is connected to the threaded sleeve 804 near the support rod 2 on the first sleeve 801. One end of the first elastic element 803 is connected to the other end of the second sleeve 802 near the linear drive mechanism 9; the threaded sleeve 804 is sleeved on the outside of the first sleeve 801 and the second sleeve 802. The end of the threaded sleeve 804 near the first sleeve 801 is threadedly connected to the outer wall of the first sleeve 801. The end of the threaded sleeve 804 near the second sleeve 802 is provided with a limiting ring 8041. The first sleeve 801, the limiting part 8021, and the limiting ring 8041 are arranged sequentially along the extension direction of the first sleeve 801. The limiting ring 8041 is used to abut against the limiting part 8021 when the linear drive mechanism 9 drives the elastic buffer assembly 8 away from the support rod 2, so that the first sleeve 801 is driven to move away from the support rod 2 via the threaded sleeve 804.

[0059] One end of the first sleeve 801 is fixed to the end of the wedge block 7 away from the support rod 2. One end of the second sleeve 802 is preferably fixed to the output part of the linear drive mechanism 9 by welding, bonding, or bolting. The first sleeve 801 is slidably fitted onto the outside of the second sleeve 802, allowing axial relative sliding between them, providing a structural basis for buffering telescopic movement. A limiting part 8021 is provided on the outer wall of the second sleeve 802. The limiting part 8021 can be a limiting ring, limiting block, or other limiting structure, which can form a mechanical abutment limit during the sliding process of the first sleeve 801 relative to the second sleeve 802, effectively limiting the maximum sliding stroke of the first sleeve 801 to avoid excessive compression of the first elastic element 803, thereby ensuring the stability of the buffering movement.

[0060] The first elastic element 803 is housed within the nested cavity of the first sleeve 801 and the second sleeve 802, achieving a concealed, built-in installation. This results in a compact structure that is resistant to external soil and debris. The first elastic element 803 can be selected from elastic buffer components such as compression springs, wave springs, and disc springs, with compression springs being preferred. Both ends of the first elastic element 803 are connected to the first sleeve 801 and the second sleeve 802, respectively. The connection can be achieved through welding, bonding, bolting, or other fixing methods. A preferred installation method is a fixed connection at one end and an abutment or detachable assembly at the other, ensuring stable elastic force transmission while facilitating component assembly and subsequent maintenance.

[0061] The threaded sleeve 804 is integrally fitted onto the outside of the first sleeve 801 and the second sleeve 802. The end of the threaded sleeve 804 near the first sleeve 801 is threadedly connected to the outer wall of the first sleeve 801, achieving adjustable assembly and fixation. A limit ring 8041 is integrally provided at the end of the threaded sleeve 804 near the second sleeve 802. The first sleeve 801, the limit part 8021, and the limit ring 8041 are arranged sequentially along the axial direction of the first sleeve 801. When the linear drive mechanism 9 drives the overall elastic buffer assembly 8 to move axially away from the support rod 2, the limit part 8021 on the second sleeve 802 can form an abutment engagement with the limit ring 8041 at the end of the threaded sleeve 804. This allows the threaded sleeve 804 to pull the first sleeve 801 to move axially synchronously, and drives the wedge block 7 to perform overall repositioning and reset. The mechanical linkage structure ensures the adjustment accuracy and synchronous movement effect of the buffer assembly, effectively improving the overall reliability of the mechanism.

[0062] See Figure 2 , Figure 3 and Figure 4 Preferably, an agricultural tillage and soil-turning device further includes a mounting housing 10. The mounting housing 10 and the outer wall of the support rod 2 together enclose a mounting cavity 1001. The linear drive mechanism 9 and the elastic buffer assembly 8 are both housed within the mounting cavity 1001, with the linear drive mechanism 9 mounted on the inner wall of the mounting housing 10. The mounting housing 10 can be fixed to the outer wall of the support rod 2 by bolt connection, welding, or snap-locking. By enclosing and forming an independent mounting cavity 1001, the precision transmission and buffering structures such as the linear drive mechanism 9 and the elastic buffer assembly 8 can be completely isolated and internally protected, effectively preventing various impurities from the field from entering the mechanism, thereby improving the service life of components such as the linear drive mechanism 9 and the elastic buffer assembly 8. Simultaneously, maintenance windows can be opened at corresponding positions on the mounting housing 10, allowing for direct observation and inspection of the internal linear drive mechanism 9 and elastic buffer assembly 8 during routine maintenance without the need for complete disassembly of the housing.

[0063] See Figure 5 and Figure 6Preferably, an agricultural tillage and soil-turning device further includes a force sensor 11, which is mounted on the support rod 2. One end of the elastic buffer assembly 8 near the support rod 2 is pressed against the force sensor 11. The force sensor 11 monitors the initial elastic preload of the elastic buffer assembly 8. The force sensor 11 can be fixed to a preset mounting point on the support rod 2 using methods such as embedded installation, flange fixing, or bolt tightening. The installation position is precise and secure, effectively avoiding the risk of sensor displacement or detachment due to operational vibration. The force sensor 11 can be selected as a strain gauge pressure sensor, piezoelectric pressure sensor, diaphragm pressure sensor, etc., suitable for static preload pressure detection and dynamic impact pressure detection scenarios. The sensor's detection end face can maintain close contact with the end of the elastic buffer assembly 8 to collect the preload pressure signal applied by the elastic buffer assembly 8, avoiding numerical deviations caused by indirect detection. By monitoring the initial preload in real time, the adjustment action of the linear drive mechanism 9 can be used to achieve precise calibration of the preload, solving the problems of inaccurate parameters and poor adaptability to working conditions caused by traditional manual adjustment of preload based on experience. This ensures that the device's avoidance trigger threshold always matches the current tillage conditions, thereby further improving the device's operational stability and intelligent adjustment accuracy.

[0064] See Figure 1 , Figure 7 and Figure 8 Preferably, an agricultural tillage and soil-turning device further includes a guide beam 12 and an elastic locking assembly 13. The guide beam 12 is mounted on the mounting frame 1, and its extension direction is perpendicular to a first direction. The guide beam 12 has an installation channel 1201 and a through hole 1202. The installation channel 1201 extends through the guide beam 12 along its extension direction, and the through hole 1202 connects the installation channel 1201 to the external environment along the radial direction of the guide beam 12. The support rod 2 is also provided with a through sleeve 201, which is slidably fitted onto the outside of the guide beam 12. The inner wall of the through sleeve 201 has an arc-shaped groove 2011. The elastic locking assembly 13 is located within the installation channel 1201 along the radial direction of the guide beam 12. The end of the locking assembly 13 facing the through hole 1202 is provided with a ball bearing 1301. The ball bearing 1301 is rotatably embedded in the end of the elastic locking assembly 13 near the through hole 1202. The ball bearing 1301 passes through the through hole 1202 and is adapted to the arc-shaped groove 2011. The elastic locking assembly 13 is used to apply an elastic force to the ball bearing 1301, so that the ball bearing 1301 is pressed against the arc-shaped groove 2011 to elastically lock the through sleeve 201 onto the guide beam 12. When the lateral force on the through sleeve 201 exceeds the elastic preload of the elastic locking assembly 13, the ball bearing 1301 overcomes the elastic force and exits the arc-shaped groove 2011. The through sleeve 201 slides along the guide beam 12 to achieve lateral clearance of the support rod 2 and the soil turning component 5 on it.

[0065] The elastic locking assembly 13 can be selected from ball spring assemblies, disc spring and top ball assemblies, wave spring and top ball assemblies, etc. The elastic locking assembly 13 can be directly installed on the inner wall of the installation channel 1201 by welding, bolt fastening or other fixed connection methods. This method is simple in structure and convenient to assemble, and locking is achieved by relying on preset elastic force. Alternatively, the elastic locking assembly 13 can be assembled on a matching drive assembly. By changing the compression of the elastic element with the help of the drive assembly, the output elastic force of the elastic locking assembly 13 can be adjusted to change the trigger elastic force threshold of lateral clearance. Under normal tillage conditions, the elastic locking assembly 13 continuously applies radial elastic force to the ball 1301. The ball 1301 is engaged in the arc-shaped groove 2011 on the inner wall of the through sleeve 201, locking the through sleeve 201 on the guide beam 12, restricting the lateral sliding of the support rod 2, and ensuring the lateral position stability of the tilling component 5. When the soil turning component 5 is subjected to a lateral impact and generates a lateral load exceeding the preset threshold, the ball bearing 1301 overcomes the elastic force of the elastic locking component 13 and disengages from the arc-shaped groove 2011. The through sleeve 201 can slide along the guide beam 12, causing the support rod 2 and the soil turning component 5 to make lateral avoidance, thus mitigating the lateral impact.

[0066] See Figure 7 and Figure 8Preferably, the elastic locking assembly 13 includes a ball bearing 1301, a ball seat 1302, a second elastic element 1303, and a limiting sleeve 1304. The ball bearing 1301 is rotatably embedded in the ball seat 1302; the ball seat 1302 is slidably disposed within the limiting sleeve 1304; the second elastic element 1303 is disposed within the limiting sleeve 1304, one end of the second elastic element 1303 is connected to the ball seat 1302, and the other end of the second elastic element 1303 is connected to the inner wall of the limiting sleeve 1304; the limiting sleeve 1304 is disposed within the installation channel 1201. The second elastic element 1303 can be selected as a compression spring, disc spring, wave spring, etc., preferably a compression spring. The connection method can be selected as welding, bonding, snap-fit, or abutment fit. One end of the second elastic element 1303 can be fixedly connected to the ball seat 1302, and the other end abuts against the inner wall of the limiting sleeve 1304, without the need for rigid fixation at both ends, facilitating assembly and disassembly. The limiting sleeve 1304 provides radial guiding constraint for the ball seat 1302 and the second elastic element 1303, allowing the second elastic element 1303 to extend and retract only radially. During normal operation, the second elastic element 1303 continuously pushes against the ball seat 1302 and the ball 1301, keeping the ball 1301 in an outward-extending state, passing through the through hole 1202 and engaging in the arc-shaped groove 2011 of the through sleeve 201, achieving elastic locking. When the lateral load exceeds the preload of the second elastic element 1303, the ball 1301 is compressed, pushing the ball seat 1302 to compress the second elastic element 1303 and retract into the limiting sleeve 1304. The ball 1301 disengages from the arc-shaped groove 2011, releasing the lock, and the through sleeve 201 can slide along the guide beam 12, completing lateral clearance. After the lateral impact is eliminated, under the elastic force of the second elastic element 1303, the ball 1301 can be re-engaged into the arc-shaped groove 2011 to achieve locking and reset.

[0067] See Figure 7 and Figure 8Preferably, an agricultural tillage and soil-turning device further includes an adjusting crossbar 14, which has a threaded adjusting section 1401 and a tapered adjusting section 1402. The adjusting crossbar 14 passes through the installation channel 1201. A ball seat 1302 is slidably inserted into the through hole 1202. The threaded adjusting section 1401 is threadedly engaged with the inner wall of the installation channel 1201 to drive the adjusting crossbar 14 to move axially along the installation channel 1201 when the adjusting crossbar 14 is rotated. A limiting sleeve 1304 is positioned near the tapered section. One end of the tapered adjustment section 1402 is provided with a third inclined surface 13041, which slides in engagement with the tapered surface 14021 of the tapered adjustment section 1402. This allows the tapered adjustment section 1402 to push the limiting sleeve 1304 through the third inclined surface 13041 when moving axially. The limiting sleeve 1304 then pushes the ball seat 1302 and the ball bearing 1301 to move radially along the through hole 1202 through the second elastic element 1303, thereby adjusting the clamping force of the ball bearing 1301 on the arc-shaped groove 2011. The adjusting crossbar 14 achieves threaded feed transmission through the threaded adjustment section 1401. Rotating the adjusting crossbar 14 will drive the adjusting crossbar 14 itself to move axially along the mounting channel 1201. The tapered adjusting section 1402 and the third inclined surface 13041 on the limiting sleeve 1304 form an inclined transmission pair, converting the axial displacement of the adjusting crossbar 14 into the radial displacement of the limiting sleeve 1304. This radial displacement is then transmitted to the ball seat 1302 and the ball bearing 1301 via the second elastic element 1303, changing the preload of the ball bearing 1301 and achieving continuous adjustment of the lateral clearance trigger load. This adjusting structure is integrated inside the installation channel 1201 of the guide beam 12, eliminating the need for a complex external adjusting handle. Its compact structure makes it less susceptible to damage from impacts by field straw, stones, etc.

[0068] See Figure 7 and Figure 8 Preferably, the ball seat 1302 is further provided with a limiting rod 13021. The limiting rod 13021 is located on one end of the ball seat 1302 facing the limiting sleeve 1304. The limiting rod 13021 is used to press against the limiting sleeve 1304 to prevent the second elastic element 1303 from being over-compressed. The limiting rod 13021 can be provided by integral molding, welding, threaded connection, or snap-fit ​​fixing. The limiting rod 13021 moves radially synchronously with the ball seat 1302. When the ball seat 1302 retracts into the limiting sleeve 1304 to its limit position, the end of the limiting rod 13021 abuts against the inner wall end face of the limiting sleeve 1304, restricting the ball seat 1302 from continuing to move inward, thus preventing the second elastic element 1303 from being pressed to a dead point and experiencing elastic failure when subjected to excessive impact load. The limit rod 13021 provides mechanical overload protection for the second elastic element 1303, maintaining the long-term stable elastic performance of the second elastic element 1303. This prevents the elastic element from being permanently crushed and losing its locking and yielding function, thereby improving the service life and operational reliability of the elastic locking assembly 13.

[0069] See Figure 7 and Figure 8 Preferably, multiple arc-shaped grooves 2011 are provided, and the multiple arc-shaped grooves 2011 are spaced apart along the axial direction of the through sleeve 201. The multiple arc-shaped grooves 2011 are arranged sequentially along the axial direction of the through sleeve 201, providing multiple sets of selectable locking points. When it is necessary to adjust the lateral installation position of the support rod 2 on the guide beam 12, the ball bearings 1301 of the elastic locking assembly 13 can be engaged with the arc-shaped grooves 2011 at different positions to lock, thereby changing the lateral position of the tillage component 5, realizing the adjustment of the tillage ridge spacing, and adapting to the ridge spacing requirements of different reclamation operations.

[0070] See Figure 7 and Figure 8 Preferably, multiple arc-shaped grooves 2011 are provided, and the multiple arc-shaped grooves 2011 are spaced apart along the circumference of the through sleeve 201; multiple through holes 1202 are provided, and the multiple through holes 1202 are spaced apart along the circumference of the guide beam 12; multiple elastic locking components 13 are provided, and the multiple elastic locking components 13 are spaced apart along the circumference of the guide beam 12, and the elastic locking components 13 correspond to and cooperate with the arc-shaped grooves 2011 and the through holes 1202 one by one. Multiple sets of elastic locking components 13 are evenly arranged circumferentially, and the balls 1301 are simultaneously engaged in the corresponding arc-shaped grooves 2011 on the inner wall of the through sleeve 201, which can form multi-point elastic support locking in the circumferential direction, disperse the lateral load generated during operation, reduce the wear of single-point balls 1301 and arc-shaped grooves 2011, and improve the stability and structural strength of locking positioning, thereby effectively suppressing the force offset of the through sleeve 201 relative to the guide beam 12.

[0071] When designing for lateral clearance, a sliding groove and pulley can be installed behind the support rod 2 as an auxiliary guiding structure. The sliding groove can be fixed to the rear side of the mounting frame 1, and the pulley is rotatably mounted on the rear side of the support rod 2, slidably embedded inside the sliding groove. During the lateral clearance process of the through sleeve 201 sliding along the guide beam 12, the pulley behind the support rod 2 provides auxiliary support and guidance by rolling along the sliding groove, constraining the rear end of the support rod 2 and preventing sagging, swaying, or torsional deviation. This ensures that both ends of the support rod 2 receive guiding support simultaneously, guaranteeing a smooth and stable lateral sliding process.

[0072] Additionally, a control panel can be installed. The control panel can be fixed to the traction equipment cab or mounting frame 1 via a bracket. Installation can be achieved using bolt fastening or snap-fit ​​assembly, facilitating operator observation and manual operation. The control panel is electrically connected to the force sensor 11 and the linear drive mechanism 9. The preload signal collected by the force sensor 11 is transmitted to the control panel, which can display the preload value of the elastic buffer component 8 in real time. The operator can input the target preload parameter on the control panel. Based on the detection signal fed back by the force sensor 11, the control panel outputs control commands to the linear drive mechanism 9, driving the linear drive mechanism 9 to extend and retract, automatically adjusting the precompression of the elastic buffer component 8 until the preload reaches the set threshold. This setup enables visualized and closed-loop control of the preload, eliminating the need for repeated manual adjustments on-site, and providing convenient operation. It also allows for quick setting of the longitudinal avoidance trigger load according to different site conditions. The control panel can be a touch screen, a physical button panel, or a simple operation panel with a digital display. Additionally, an over-limit warning function can be added. When the preload exceeds the preset safety range, the control panel will issue a warning, which will help operators to promptly check for equipment abnormalities and further improve the intelligence level and operational safety of the device.
