Description

Technical Field

[0001] This invention relates to the field of agricultural machinery technology in hilly and mountainous areas, specifically to a lateral and longitudinal movement mountain tracked tractor. Background Technology

[0002] my country's hilly and mountainous regions are vast, with complex and varied topography, and arable land is mostly on slopes. Due to the special nature of the working environment, the level of agricultural mechanization in these areas lags significantly behind that in plains areas. Currently, tracked tractors, with their low ground pressure and strong mobility, have become the main power machinery in hilly and mountainous areas. However, existing conventional tracked tractors still have significant structural limitations and applicability issues in actual sloping farmland operations.

[0003] The main problem is that most existing tracked tractors use a rigid connection between the chassis and the body, lacking the ability to actively adjust the center of gravity. When the tractor is working laterally or climbing on sloping farmland, the body will tilt with the slope, causing a passive shift in the machine's center of gravity. This shift in the center of gravity directly results in uneven distribution of contact pressure between the two tracks and the ground: one track has excessive traction, while the other has insufficient traction or even hangs in the air. This not only prevents effective traction output, severely affecting work efficiency, but also leads to a significant decrease in vehicle stability, insufficient climbing ability, and even rollover accidents, posing a considerable safety hazard.

[0004] In addition, in terms of the transmission system, existing mountain tractors often struggle to balance the smoothness of power transmission and load-bearing capacity when dealing with complex terrain. Under frequent load changes and bumpy conditions, transmission efficiency may decrease or precision may be insufficient, making it difficult to meet the needs of efficient and precise modern mountain agricultural operations. Therefore, there is an urgent need for a new type of tractor that can adjust the center of gravity position in real time according to terrain conditions and has excellent transmission performance. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides a lateral traverse mountain tracked tractor, which solves the problems of existing tractors being unsuitable for hilly and mountainous operating environments, being affected by slope factors during operation, having uneven track ground pressure distribution when the tractor is in different operating states, and being prone to problems such as hill-climbing wheelies, steering skidding, and poor straight-line driving and operating stability.

[0012] Preferably, the engine bracket is rotatably connected to the movable frame via a pin, and lateral adjustment hydraulic cylinders are fixedly installed on both sides of the movable frame, with the upper end of the lateral adjustment hydraulic cylinders fixedly connected to the diesel engine.

[0013] Preferably, the movable frame is connected to the unleveled frame via a longitudinal adjustment hydraulic cylinder, and a three-point suspension system is installed on the upper part of the unleveled frame.

[0014] Preferably, the seat angle adjustment mechanism includes a cylinder, a guide block is fixedly connected to the output end of the cylinder, a limit block is fixedly connected to the outside of the guide block, a rack plate is fixedly connected to the right side of the outside of the guide block, a rotating shaft is rotatably connected to the middle of the seat support frame, a spur gear is fixedly connected to the outside of the rotating shaft, the spur gear meshes with the rack plate, a connecting block is fixedly connected to the top of the rotating shaft, an auxiliary rod is fixedly connected to the lower right side of the connecting block, a connecting seat is fixedly connected to the upper part of the connecting block, and the top of the connecting seat is installed at the bottom of the seat assembly.

[0016] This invention provides a lateral traverse and longitudinal movement mountain tracked tractor. It has the following beneficial effects:

[0017] 1. This invention achieves the lateral and longitudinal shift of the machine's center of gravity by coordinating the actions of the lateral and longitudinal adjustment hydraulic cylinders. When working on slopes, the lateral adjustment hydraulic cylinder drives the machine to rotate around the pivot, which can offset the risk of rollover caused by the body tilting. The longitudinal adjustment hydraulic cylinder changes the length of the machine, which can optimize the distribution of the center of gravity to cope with steep slopes. This active center of gravity adjustment mechanism effectively solves the problems of unstable center of gravity, easy rollover, and insufficient grip when climbing slopes in traditional tractors under complex terrain.

[0018] 2. This invention employs a seat angle adjustment mechanism consisting of a cylinder, a rack and pinion, and a spur gear. The extension and retraction of the cylinder drives the rack to move horizontally, which in turn drives the spur gear and the seat shaft to rotate, thus achieving flexible adjustment of the left and right angles of the seat. This design allows the driver to easily obtain dual visibility of the road conditions ahead and the working equipment behind without having to twist their waist or turn their head significantly. This fundamentally eliminates occupational strain on the lumbar and cervical spine caused by long-term back-turning during work, while also avoiding operational errors caused by blind spots, thereby improving driving safety and comfort.

[0019] 3. The present invention incorporates a structure in the transmission system in which a telescopic shaft sleeve engages with a splined shaft. When the longitudinal adjustment hydraulic cylinder drives the movable frame to extend or retract to adjust the center of gravity, the splined shaft can slide freely axially within the telescopic shaft sleeve. Simultaneously, the transmission of torque is maintained through spline engagement. This design cleverly solves the problem of power interruption when the variable wheelbase chassis changes shape, ensuring that the tractor can maintain stable power output while adjusting its posture, thus guaranteeing the continuity of operation.

[0031] Please see the appendix Figure 2 -Appendix Figure 5 The seat angle adjustment mechanism includes a cylinder 34, a guide block 38 fixedly connected to the output end of the cylinder 34, a limit block 39 fixedly connected to the outside of the guide block 38, a rack plate 37 fixedly connected to the right side of the outside of the guide block 38, a rotating shaft 35 rotatably connected to the middle of the seat support frame 4, a spur gear 36 fixedly connected to the outside of the rotating shaft 35, the spur gear 36 meshing with the rack plate 37, a connecting block 41 fixedly connected to the top of the rotating shaft 35, an auxiliary rod 43 fixedly connected to the lower right side of the connecting block 41, a connecting seat 42 fixedly connected to the upper part of the connecting block 41, the top of the connecting seat 42 being installed at the bottom of the seat assembly 2, a limit groove 40 being opened inside the seat support frame 4, the limit block 39 being slidably connected inside the limit groove 40, an arc groove 44 being opened on the right side of the inside of the seat support frame 4, the auxiliary rod 43 being slidably connected inside the arc groove 44, a fixing block 33 being fixedly connected to the upper left side of the seat support frame 4, and the cylinder 34 being fixedly connected inside the fixing block 33.

[0032] Specifically, the seat angle adjustment mechanism includes a cylinder 34 fixedly connected to a fixing block 33 on the upper left side of the seat support frame 4. A guide block 38 is fixedly connected to the output end of the cylinder 34. A rack plate 37 is fixedly connected to the outer right side of the guide block 38. A rotating shaft 35 is rotatably connected to the middle of the seat support frame 4. A spur gear 36 is fixedly connected to the outside of the rotating shaft 35, and the spur gear 36 meshes with the rack plate 37.

In order to ensure the smoothness of the seat adjustment process and the structural strength, the guide block 38 is fixedly connected to the outside of the limiting block 39. The limiting block 39 is slidably connected in the limiting groove 40 opened inside the seat support frame 4 to limit the stroke and direction of linear movement. At the same time, the lower right side of the connecting block 41 is fixedly connected to the auxiliary rod 43.

Through the cooperation of the auxiliary rod 43 and the arc-shaped groove 44, auxiliary support and guidance are provided for the rotation of the seat.

[0033] Working principle: When lateral adjustment of the center of gravity is required, the extension and retraction of the lateral adjustment hydraulic cylinder 15 pushes the machine body to rotate around the pin shaft 30 and the hollow pin shaft assembly 29 by a certain angle to achieve lateral adjustment of the machine body; when longitudinal adjustment of the center of gravity is required, the extension and retraction of the telescopic shaft sleeve 25 and the spline shaft 24 move forward or backward by a certain distance to ensure power transmission, and the extension and retraction of the longitudinal adjustment hydraulic cylinder 12 will cause the movable frame 16 to move forward or backward by a certain distance to achieve longitudinal adjustment of the machine body; it can realize the lateral and longitudinal adjustment of the tractor, improve the stability and climbing performance of the tractor in hilly and mountainous areas, and improve the working environment and safety of the driver when operating in hilly and mountainous areas.

[0034] When the seat angle needs to be adjusted to the left, the operator controls the cylinder 34 to retract via the control panel, which moves the guide block 38 fixedly connected to the output end. The movement of the guide block 38 moves the rack plate 37 fixedly connected to the outer right side synchronously. When the rack plate 37 moves, it rotates the spur gear 36 externally meshing with it. The rotation of the spur gear 36 causes the rotating shaft 35 fixedly connected in the middle to rotate inside the seat support frame 4. When the rotating shaft 35 rotates, it causes the connecting block 41 fixedly connected at the top to rotate. The rotation of the connecting block 41 causes the auxiliary rod 43 fixedly connected to the lower right side to rotate inside the arc groove 44. When the connecting block 41 rotates, it causes the connecting seat 42 fixedly connected at the upper part to rotate. The rotation of the connecting seat 42 causes the seat assembly 2 mounted at the top to rotate, thus completing the adjustment operation of the seat to the left.

[0035] When the seat angle needs to be adjusted to the right, the seat first resets, and then the extension movement of cylinder 34 moves the guide block 38 fixedly connected to the output end. The movement of guide block 38 moves the rack plate 37 fixedly connected to the outer right side synchronously. When rack plate 37 moves, it drives the externally meshing spur gear 36 to rotate. The rotation of spur gear 36 drives the rotating shaft 35 fixedly connected in the middle to rotate inside the seat support frame 4. When rotating shaft 35 rotates, it drives the connecting block 41 fixedly connected at the top to rotate. The rotation of connecting block 41 drives the auxiliary rod 43 fixedly connected to the lower right side to rotate inside the arc groove 44. When connecting block 41 rotates, it drives the connecting seat 42 fixedly connected at the upper part to rotate. The rotation of connecting seat 42 drives the seat assembly 2 mounted at the top to rotate, thus completing the seat adjustment operation to the right. This allows the operator to easily adjust the left and right angle of the seat during the use of the mountain tracked tractor without having to turn around or turn their head. It allows the operator to take into account the road conditions in front and the work situation behind, fundamentally eliminating the problem of physical strain, thereby improving driving comfort and work safety in complex mountain conditions.
