[0002] Deep tillage is the process of using equipment to deeply pulverize the soil. This process prevents soil turbulence and increases nutrients, water, and oxygen, thereby increasing productivity. There are two main types of subsoilers available: one that uses a tractor-driven deep tillage and pulverization head, and one that uses a newly developed walking mechanism to drive the deep tillage and pulverization box. These machines primarily consist of a walking mechanism, frame, cab, power system, and deep tillage and pulverization mechanism.

[0003] A patent document in China with application number 202011597391.1 and publication date 2021.3.12 discloses a deep plowing crushing and loosening machine, including a front traction device, a connecting mechanism, and a rear floating oil tank; the front traction device is connected to the rear floating oil tank through a connecting mechanism, and the connecting mechanism includes a front connecting block, a rear connecting block, a joint bearing and a hydraulic cylinder connecting mechanism; one end of the front connecting device is fixedly connected to the front traction device, and the other end of the connecting device is hinged to the joint bearing, and an articulated shaft passes through the joint bearing, one end of the rear connecting block is hinged to the articulated shaft, and the other end of the rear connecting block is fixedly connected to the rear floating oil tank.

[0004] The front traction device of the tiller is fixedly connected to the front connecting block, and the connection between the front traction device and the front connecting block is prone to breakage when subjected to stress; the rear floating oil tank is fixedly connected to the rear connecting block, and the front connecting block and the rear connecting block are hinged, and the rear connecting block can only rotate left and right relative to the front connecting block; along the axial direction of the hinge shaft, the rear connecting block is fixed relative to the front connecting block, and the rear connecting block is fixed relative to the front traction device; when the tiller is traveling on an uneven road, the front traction device and the rear floating oil tank are at different levels, which will cause the connection between the front traction device and the rear floating oil tank to be disconnected.

[0005] And like the prior art similar to the above-mentioned patent document, the connection between the walking swing frame and the load-bearing wheel of the walking swing assembly in this structure is only the connection between the two ends of the load-bearing wheel and the walking swing frame. During the process of loosening the soil with the plow blade, due to the different loads of the tiller, different degrees of load will be exerted on the load-bearing wheel, which will easily cause the load-bearing wheel to bear too much load, thereby affecting the walking operation. Summary of the Invention

[0006] The present invention provides a power traction device for a floating deep tillage and crushing tiller, in which a first articulated seat is movably connected to a connecting seat. The first articulated seat rotates relative to the connecting seat to consume energy generated by the force at the connection between the first articulated seat and the connecting seat, thereby reducing the risk of damage to the connecting seat and the steering component. In addition, during the movement of the tiller, the longitudinal load can be better borne, thereby facilitating walking operations.

[0007] To achieve the above-mentioned purpose, the technical solution of the present invention is: a floating deep tillage and crushing ripper power traction device, including a ripper frame and a traveling device, the ripper frame includes a frame body and a steering member, a connecting seat is provided at one end of the frame body, the steering member includes a steering bracket, a front connecting block is provided on one side of the steering bracket, and a first articulated seat is provided on the other side of the steering bracket; the first articulated seat and the connecting seat are movably connected through a connecting column; along the height direction of the frame body, the steering member is rotatably arranged relative to the frame body; the front connecting block is hingedly connected to a rear connecting block at one end away from the steering bracket, and a fixed shaft is provided on both sides of the frame body and the rear connecting block; a fixed shaft is provided for installing the traveling device.

[0008] In the above arrangement, the frame is used to carry the front traction device, and the front connecting block is hinged to the rear connecting block for carrying the rear floating oil tank; when the horizontal heights of the front traction device and the rear floating oil tank are different; the first hinge seat is movably connected to the connecting seat, and then the front connecting block and the frame are movably connected; thereby, the rear floating oil tank can be rotated relative to the front traction device along the height direction of the frame; the first hinge seat is rotated relative to the connecting seat to consume the energy generated by the force at the connection between the first hinge seat and the connecting seat, thereby reducing the risk of damage to the connecting seat and the steering member; thereby, the connection between the frame and the front connecting block, and the connection between the frame and the rear floating oil tank are not easy to disconnect.

[0009] The walking device includes a walking bracket, a walking drive assembly and a walking swing assembly. A through hole matching the fixed shaft is provided in the middle of the walking bracket, and a locking device matching the fixed shaft is provided at one end of the fixed shaft passing through the through hole. The walking drive assembly includes a walking track, a walking drive wheel and two walking driven wheels. The walking swing assembly includes more than one walking swing frame and a load-bearing wheel. The top end of the walking swing frame is hinged to the bottom of the walking bracket, and load-bearing wheels are distributed on both sides of the bottom end of the walking swing frame. The walking track is sleeved on the walking drive wheel, the walking driven wheel and the load-bearing wheel.

[0010] The above arrangement, by arranging through holes on the walking bracket, allows the walking device to pass through the through holes and be sleeved on the fixed shafts on both sides of the frame body and the rear connecting block and be locked and fixed by the locking device, so that the walking device can be fixed on the tiller frame, and then the tiller frame is driven to travel by the walking device; at the same time, the crawler track and the walking driven wheel are driven to move by the rotation of the walking driving wheel, and the load-bearing wheels of the walking swing assembly swing on the walking swing frame under the drive of the crawler track. During the travel of the tiller, after the walking device is fixed to the walking bracket by the locking device, the walking swing assembly swings upward when encountering a suddenly higher ground, thereby preventing the upward force from being mainly concentrated on the walking device and the loosening machine locking device when subjected to the upward swinging force due to the absence of the walking swing assembly, thereby causing the locking device to be easily damaged. In addition, the longitudinal load can be better carried, and the vehicle can travel reliably and smoothly for easy operation.

[0011] Furthermore, the connecting seat includes two spaced-apart connecting ears, and the first hinge seat is arranged between the two connecting ears; the first hinge seat includes a first through-hole, and the first through-hole passes through the first hinge seat; the connecting ear includes a second through-hole, and the connecting column is passed through the first through-hole and the second through-hole; a limiting device is provided between the connecting seat and the first hinge seat, and the limiting device limits the rotation amplitude of the first hinge seat.

[0012] The above arrangement, which connects the connecting post, the connecting ear, and the first hinge seat, has a simple structure. A limit device is provided to limit the rotation range of the first hinge seat to prevent excessive rotation between the connecting seat and the first hinge seat. At the same time, when the first hinge seat reaches the limit position, the limit device provides support for the first hinge seat. In this way, the support effect between the connecting seat and the first hinge seat is good after reaching the limit position, and the rigid connection strength is high.

[0013] Furthermore, the limiting device includes a limiting member, a limiting mounting hole and a limiting groove; the limiting grooves are arranged at both ends of the first hinge seat; the limiting groove is recessed inward from the end surface of the first hinge seat, and the limiting groove is located on one side of the first through-hole; the limiting mounting hole is arranged in the connecting ear, the limiting member is passed through the limiting mounting hole, and one end of the limiting member is fixedly connected to the connecting ear; the other end of the limiting member extends into the limiting groove; the length between the top of the limiting groove and the bottom of the limiting groove is greater than the length between the top surface of the limiting member and the bottom surface of the limiting member, and the limiting groove is movably arranged relative to the limiting member.

[0014] In the above arrangement, the first articulated seat rotates relative to the connecting ear, the limit member is fixedly connected to the connecting ear, and the limit member limits the first articulated seat; limit grooves and limit members of different sizes are provided so that the first articulated seat can rotate relative to the limit member; along the height direction of the frame, the steering member rotates upward, and when the top of the limit groove contacts the top surface of the limit member, the limit member limits the first articulated seat; along the height direction of the frame, the steering member rotates downward, and when the bottom of the limit groove contacts the bottom and top surfaces of the limit member, the limit member limits the first articulated seat; thereby realizing the limitation of the steering member along the two rotation directions of the steering member.

[0015] Furthermore, the connecting ear and the limiting member are connected by a fixing device; the fixing device includes a cover plate and two or more connecting members, the cover plate is arranged on the outside of the connecting ear, one or more first connecting holes are provided on the connecting ear, and a second connecting hole is provided in the limiting member; the connecting members are passed through the through holes of the cover plate, one connecting member passes through a through hole to be connected to the first connecting hole, and the other connecting member passes through a through hole to be connected to the second connecting hole.

[0016] The above arrangement connects the limiting member and the connecting ear simultaneously through the fixing device, so that the limiting member and the connecting ear are fixedly connected, and the structure is simple.

[0017] Furthermore, the steering member further includes a second articulated seat and a third articulated seat, and the second articulated seat and the third articulated seat are arranged above the front connecting block.

[0018] In the above arrangement, the second articulated seat and the third articulated seat are both used to install hydraulic cylinders, and the other ends of the hydraulic cylinders are connected to the rear floating oil tank to drive the rear floating oil tank to swing left and right relative to the front traction device.

[0019] Furthermore, the locking device includes a first connecting ring, a second connecting ring, and a detachable bolt. One end face of the first connecting ring is in contact with a side face of the traveling bracket, and the other end face of the first connecting ring is fixedly connected to one end face of the second connecting ring. The other end face of the second connecting ring is provided with a groove that matches the detachable bolt.

[0020] Furthermore, the outer ring radius of the first connecting ring is larger than the outer ring radius of the second connecting ring, and there are more than two grooves, which are evenly distributed on the other end face of the second connecting ring. One end of the detachable bolt slides into the groove, passes through the through hole of the fixed shaft, and then slides out of the groove. The nut cooperates with the detachable bolt to lock it.

[0021] The above arrangement facilitates the passage of detachable bolts through the grooves and through holes, and at the same time, the locking of the fixed shaft is completed by cooperating with the nut. In addition, multiple grooves are arranged and spaced apart, and can be locked in different directions, which is convenient for installation and disassembly. At the same time, the outer ring of the first connecting ring is larger than the outer ring of the second connecting ring, so that the contact area of ​​the first connecting ring connected to the walking bracket is large, and the smaller size of the outer ring of the second connecting ring can make it better locked by the detachable bolts.

The two ends of the connecting rod are fixedly connected to the two oppositely arranged swing frames. The middle of the swing plate is higher than the two ends, and the two ends of the swing plate are respectively rotatably connected to the load-bearing wheels. The middle of the swing plate is rotatably connected to the bottom of the walking bracket through a through hole.

[0023] The above setting is to set a swing plate, and the middle part of the swing plate is higher than the two ends, so that when the load-bearing wheel receives the force of the ground, the load-bearing wheel can swing under the drive of the swing plate. In addition, the connecting rod can make the walking swing group have better stability and load-bearing capacity when in contact with the walking track.

[0024] Furthermore, the travel driving wheel is arranged at the top end of the travel bracket, and the two travel driven wheels are arranged on both sides of the travel bracket in a triangular shape.

[0025] The above arrangement, by arranging the travel driving wheel at the top of the travel bracket and arranging the travel driven wheels on both sides of the travel bracket, is arranged in a triangular shape, which can increase the contact distance with the ground and make walking more convenient.

[0026] Furthermore, a connecting device is provided at the through-hole position of the walking bracket corresponding to the walking swing assembly, and the connecting device includes a connecting plate and a fixing piece.
