The maintenance is convenient. The segmented pedal design makes the maintenance work more convenient and fast, shortens the maintenance time, reduces the maintenance cost, and improves the availability and service life of the equipment.

[0009] In a preferred embodiment of the present invention, a cab is fixed to the upper end of the bracket assembly. The cab includes a frame structure and a windshield embedded around the frame structure. An instrument display screen is disposed inside the cab, and the instrument display screen is installed on one side below the front windshield of the cab; the angle of the instrument display screen is adjustable by a damping hinge.

[0010] In a preferred embodiment of the present invention, the seat and the steering wheel assembly are both disposed inside the cab. The main fuel tank housing assembly and the auxiliary fuel tank housing assembly are respectively fixed to both sides of the bracket assembly, and the main fuel tank housing assembly and the auxiliary fuel tank housing assembly are disposed outside the cab. The comfort is improved. The reasonable space layout and ergonomic design make the driver more comfortable during operation, effectively reduce fatigue, and improve work efficiency and driving experience.

[0011] In a preferred embodiment of the present invention, a limit retaining groove through which a continuously variable transmission handle passes is formed on the transmission handle maintenance and installation plate, and the electronic hand throttle knob is rotatably installed on the upper surface of the electronic hand throttle knob; a shift groove through which the shift operating handle passes is formed on the surface of the shift handle maintenance and installation plate. The present invention solves the existing problems and improves the overall performance of the tractor by optimizing the cab space layout, adopting ergonomic design, and innovating the segmented pedal structure.

[0012] In a preferred embodiment of the present invention, the shift operating handle, the continuously variable transmission handle, and the electronic hand throttle knob are symmetrically arranged with the seat as the center. The corresponding shift operating handles and continuously variable transmission handles on the left and right sides are consistent in position, shape, and operating force. This allows the driver to have the same operating experience whether using the left hand or the right hand, reducing the inconvenience caused by differences in operating habits; the symmetrical layout and ergonomic design enable the driver to easily and naturally operate each component, effectively reducing operating fatigue and making it less likely to feel tired during long-term operation.

[0013] In a preferred embodiment of the present invention, the length and angle of the shift control handle conform to the natural stretching and force-generating posture of the human arm; the size and touch of the control buttons on the control panel are suitable for finger pressing; the spacing between the various operating components is reasonable to avoid mutual interference during operation; the shock absorption and noise reduction design is adopted to reduce the vibration and noise transmitted to the driver during operation; the comfortable operating experience helps the driver to control the tractor more accurately, reduce operating errors, and thus improve work efficiency and quality.

[0014] In a preferred embodiment of the present invention, the steering wheel assembly has a multi-directional adjustment function, including up and down height adjustment and front and rear distance adjustment. The height adjustment is achieved through an electric or manual lifting mechanism, and the adjustment range is 5 cm, which can meet the needs of drivers of different heights. The front and rear distance adjustment uses a slide rail and a locking device, which can be adjusted freely, so that the driver can adjust the distance between the steering wheel and the body according to the length of his own arm to adapt to the different operating habits of the driver.

[0015] In a preferred embodiment of the present invention, a shock absorbing system is provided between the seat and the seat mounting plate.

[0016] The existing tractor seat is fixed, not easy to adjust, and cannot accommodate people of different sizes. In addition, during the maintenance process, it cannot be moved back, and the maintenance space cannot be expanded. Therefore, the specific implementation plan of the cab of the light crawler tractor according to this application is as follows: In a preferred embodiment of the present invention, a base is fixedly installed on the upper surface of the seat mounting plate, and a slide A is slidably connected to the base, a tooth block is fixed to the slide A, a rack is installed on the base, the tooth block is clamped with the rack, a pull rod is fixed to the rack, the pull rod slides through the base, a compression spring is connected between the rack and the base, a lever is installed on one side of the base, and one end of the lever is connected to the pull rod.

[0017] In a preferred embodiment of the present invention, two pull rods are arranged in parallel, and the two pull rods are respectively arranged at the two ends of the rack, and a connecting rod is connected between the two pull rods. The connecting rod rotating sleeve is provided with a sliding sleeve, and the sliding sleeve is fixed with a rotating shaft. The rotating shaft is rotatably clamped on the end of the lever, and the rotation fulcrum of the lever is close to one end of the rotating shaft.

[0018] By toggling one end of the lever, the other end of the lever pulls the pull rod to slide, causing the rack to slide away from the tooth block and compressing the compression spring. The rack is separated from the tooth block so that the slide A can slide back and forth along the base, which is convenient for adjusting the position of the seat. After sliding to the desired position, release the lever, and the compressed compression spring pushes the rack to slide and engage with the tooth block, thereby locking the slide A and facilitating rearward movement, thereby increasing the internal space of the cab and facilitating inspection and maintenance operations.

[0019] In a preferred embodiment of the present invention, a slide rail is fixed to the seat mounting plate, and a slider is slidably clamped on the upper surface of the slide rail. The slider is fixedly connected to the slide seat A.

[0020] Different heights have different height requirements for the backrest. However, the backrests of current seats are all fixed. Therefore, according to the specific implementation of the light tracked tractor cab in this application: In a preferred embodiment of the present invention, the seat includes a seat cushion and a backrest. A support rod is fixed to the slide seat A. A slide seat B is slidably clamped on the support rod. A screw rod is rotatably installed on the support rod. The upper end of the screw rod is in threaded connection with a threaded through hole formed in the slide seat B. A motor A for driving the screw rod to rotate is fixed to the support rod. The backrest is installed at the upper end of the slide seat B.

[0021] In a preferred embodiment of the present invention, the motor A is fixedly connected to the slide seat B, and the drive shaft of the motor A is in transmission connection with the lower end of the screw rod through a reduction gear.

[0022] By controlling the motor A to drive the screw rod to rotate forward, the slide seat B is pushed upward. By controlling the motor A to drive the screw rod to rotate in the reverse direction, the slide seat B is controlled to move downward, realizing the adjustment of the up and down position of the backrest, which is convenient for personnel of different heights to adjust and use.

[0023] A suitable inclination angle of the seat backrest can relieve the fatigue of the staff. Due to different heights, body shapes, and personal preferences, the required inclination angles of the backrests are different. Therefore, according to the specific implementation of the light tracked tractor cab in this application: In a preferred embodiment of the present invention, a shaft rod is rotatably installed at the upper end of the slide seat B. A worm gear is coaxially fixed to the shaft rod. A motor B is fixed to the upper end of the slide seat B. A worm is coaxially fixed to the drive shaft of the motor B. The worm is meshed with the worm gear. Mounting plates are respectively fixed to both ends of the shaft rod. The mounting plates are fixedly connected to the backrest.

[0024] In a preferred embodiment of the present invention, mounting holes are formed in the mounting plates. Screws are arranged in the mounting holes. The screws are in threaded connection with the back of the backrest. A bearing seat is installed at the upper end of the slide seat B. A bearing is installed in the bearing seat. The inner ring of the bearing is fixedly sleeved on the surface of the shaft rod.

[0025] By controlling the motor B to drive the worm to rotate forward and backward, the meshing worm drives the worm wheel to rotate, and then drives the shaft rod to rotate. The rotation of the shaft rod synchronously drives the adjustment of the backrest angle. Due to the reverse self-locking characteristic of the meshing of the worm and the worm wheel, the shaft rod will not drive the worm wheel to rotate when subjected to torsion, which is convenient for adjustment and use, and realizes the effect of adjustment and locking. It has functions such as backrest tilt angle adjustment and seat height adjustment. The driver can easily adjust the seat position and angle according to his own body size and driving habits, and find the most comfortable driving posture.

[0026] The existing seat shock absorption usually uses shock absorption springs to perform shock absorption in the up and down directions. The shock absorption effect is average, and the upper surface of the seat is sunken, so it is easy to accumulate water when the tractor is parked outdoors. Therefore, the following is based on the specific implementation plan of the cab of the light tracked tractor of the present application: In a preferred embodiment of the present invention, a rotating rod is rotatably installed on the sliding seat A, a support tube is fixed on the side wall of the rotating rod, a sliding rod is hinged at the bottom of the seat cushion, one end of the sliding rod is slidably inserted into the support tube, a shock absorption spring is connected between the support tube and the sliding rod, a rubber ring is clamped in a limiting groove opened on the outer wall of the sliding rod, the rubber ring is in sealed contact with the inner wall of the support tube, a damping hole is opened at the bottom of the support tube, and one end of the seat cushion is hinged to the lower end of the sliding seat B.

[0027] In a preferred embodiment of the present invention, two support tubes are arranged in parallel, the sliding rod, the support tube and the shock absorption spring are arranged in one-to-one correspondence, an arc-shaped connecting plate is fixed at the rear end of the seat cushion, and one end of the arc-shaped connecting plate is hinged to the lower end of the sliding seat B through a hinge seat.

[0028] When the seat cushion is not subjected to external force, the seat cushion is in an inclined state. When the seat cushion is subjected to downward gravity, while compressing the shock absorption spring, it pushes the rotating rod to rotate by a certain angle, so that the upper surface of the seat cushion is in a parallel state, improving the seat comfort. And when not sitting, it is in an inclined state, and water will not accumulate or impurities will not gather; when driving on a bumpy road section, the shock absorption spring expands and contracts in cooperation with the damping characteristic of the damping hole to achieve the shock absorption effect, and the seat cushion has an inclined swing amplitude. Compared with the traditional up and down swing amplitude, this shock absorption design in the inclined direction divides the force displacement in the single up and down direction into two directions of up and down, front and back, making the swing amplitude smaller and the shock absorption effect better.

[0029] Improved comfort: The ergonomic shape design, good shock absorption performance and adjustable function can effectively reduce the fatigue of the driver and improve the comfort of long-term driving.

[0030] Health guarantee: The correct sitting posture support and shock absorption design help to reduce the strain on the waist, neck and other parts, reduce the risk of the driver suffering from occupational diseases, and guarantee physical health.

[0031] Improved work efficiency: A comfortable seat environment enables the driver to maintain a good state, be more focused on the operation, and thus improve work efficiency and operation quality.

[0032] Additional aspects and advantages of the present application will be given in part in the following description, will become apparent in part from the following description, or will be learned through the practice of the present application. Brief Description of the Drawings

[0049] In a specific embodiment of the present invention, a shock absorption system is provided between the seat 300 and the seat installation plate 110.

[0050] The existing tractor seats are fixed, not easy to adjust, cannot adapt to people of different body sizes to sit on, and during the overhaul process, they cannot be moved backward, and the overhaul space cannot be expanded. Therefore, the following refers to the drawings for the specific implementation plan of the light tracked tractor cab of the present application: Specifically, if Figures 6-8 As shown, in a specific embodiment of the present invention, a base 350 is fixedly installed on the upper surface of the seat mounting plate 110, and the base 350 is slidably connected to a slide A370, and a tooth block 371 is fixed to the slide A370, and a rack 351 is installed on the base 350, and the tooth block 371 is engaged with the rack 351, and a pull rod 353 is fixed to the rack 351, and the pull rod 353 slides through the base 350, and a compression spring 355 is connected between the rack 351 and the base 350, and a lever 390 is installed on one side of the base 350, and one end of the lever 390 is connected to the pull rod 353.

[0051] In a specific embodiment of the present invention, two pull rods 353 are arranged in parallel, and the two pull rods 353 are respectively arranged at the two ends of the rack 351. A connecting rod 357 is connected between the two pull rods 353. The connecting rod 357 is rotatably sleeved with a sliding sleeve 358, and the sliding sleeve 358 is fixed with a rotating shaft 359. The rotating shaft 359 is rotatably clamped on the end of the lever 390, and the rotation fulcrum of the lever 390 is close to one end of the rotating shaft 359.

[0052] By toggling one end of the lever 390, the other end of the lever 390 pulls the pull rod 353 to slide, so that the rack 351 slides away from the tooth block 371 and compresses the compression spring 355. The rack 351 is separated from the tooth block 371 so that the slide A370 can slide back and forth along the base 350, which is convenient for adjusting the position of the seat 300. After sliding to the desired position, the lever 390 is released, and the compressed compression spring 355 pushes the rack 351 to slide and engage with the tooth block 371, thereby locking the slide A370 and facilitating rearward movement, thereby increasing the internal inspection space of the cab 190 and facilitating inspection and maintenance operations.

[0053] In a specific embodiment of the present invention, a slide rail 111 is fixed to the seat mounting plate 110, a slider 113 is slidably engaged on the upper surface of the slide rail 111, and the slider 113 is fixedly connected to the slide seat A370.

[0054] Different heights have different requirements for the height of the backboard, but the backboards of the current seats are all fixed. For this reason, the following is a specific implementation plan of the cab of the light crawler tractor according to the present application with reference to the accompanying drawings: Specifically, if Figures 6-10As shown in the figure, in a specific embodiment of the present invention, the seat 300 includes a seat cushion 310 and a backrest 330. A support rod 320 is fixed to the sliding seat A370. The support rod 320 is slidably clamped with a sliding seat B321. A screw rod 325 is rotatably installed on the support rod 320. The upper end of the screw rod 325 is in fit connection with a threaded through hole formed in the sliding seat B321. The support rod 320 is fixed with a motor A323 for driving the screw rod 325 to rotate. The backrest 330 is installed at the upper end of the sliding seat B321.

[0055] In a specific embodiment of the present invention, the motor A323 is fixedly connected to the sliding seat B321, and the drive shaft of the motor A323 is in transmission connection with the lower end of the screw rod 325 through a reduction gear.

[0056] By controlling the motor A323 to drive the screw rod 325 to rotate forward, the sliding seat B321 is pushed to move upward. By controlling the motor A323 to drive the screw rod 325 to rotate reversely, the sliding seat B321 is controlled to move downward, so as to adjust the up-and-down position of the backrest 330, which is convenient for personnel of different heights to adjust and use.

[0057] The inclination angle of the seat backrest is appropriate, which can relieve the fatigue of the staff. Due to different heights, different body shapes, and personal preferences, the required inclination angles of the backrest are different. Therefore, the following is a specific implementation plan of the light crawler tractor cab of the present application with reference to the accompanying drawings: Specifically, as Figures 6-11 shown, in a specific embodiment of the present invention, a shaft rod 326 is rotatably installed at the upper end of the sliding seat B321. A worm gear 327 is coaxially fixed to the shaft rod 326. A motor B328 is fixed to the upper end of the sliding seat B321. A worm 329 is coaxially fixed to the drive shaft of the motor B328. The worm 329 meshes with the worm gear 327. Installation plates are respectively fixed to both ends of the shaft rod 326, and the installation plates are fixedly connected to the backrest 330.

[0058] In a specific embodiment of the present invention, installation holes are formed in the installation plates, and screws are arranged in the installation holes. The screws are in threaded connection with the back of the backrest 330. A bearing seat is installed at the upper end of the sliding seat B321, and a bearing is installed in the bearing seat. The inner ring of the bearing is fixedly sleeved on the surface of the shaft rod 326.

[0059] By controlling the motor B328 to drive the worm 329 to rotate forward and backward, the engaged worm 329 drives the worm wheel 327 to rotate, thereby driving the shaft rod 326 to rotate. The rotation of the shaft rod 326 synchronously drives the adjustment of the angle of the backrest 330. Due to the reverse self-locking characteristic of the meshing between the worm 329 and the worm wheel 327, the shaft rod 326 will not drive the worm wheel 327 to rotate when subjected to torsion, which is convenient for adjustment and use, and realizes the effect of adjustment and locking. It has the functions of adjusting the inclination angle of the backrest 330 and the height of the seat 300, etc. The driver can easily adjust the position and angle of the seat 300 according to his own body size and driving habits to find the most comfortable driving posture.

[0060] The existing seat shock absorption usually uses shock absorbers to carry out shock absorption in the up and down directions, and the shock absorption effect is average. In addition, the upper surface of the seat is sunken, and it is easy to accumulate water when the tractor is parked outdoors. Therefore, the following is a specific implementation plan of the cab of the light tracked tractor according to the present application with reference to the attached drawings: Specifically, as Figures 6-12 shown, in the specific implementation manner of the present invention, the sliding seat A370 is rotatably installed with a rotating rod 710, a support tube 711 is fixed on the side wall of the rotating rod 710, one end of the seat cushion 310 is hinged with a sliding rod 311, one end of the sliding rod 311 is slidably inserted into the support tube 711, a shock absorption spring 730 is connected between the support tube 711 and the sliding rod 311, a rubber ring is clamped in a limiting groove opened on the outer wall of the sliding rod 311, the rubber ring is in sealing contact with the inner wall of the support tube 711, a damping hole 713 is opened at the bottom of the support tube 711, and one end of the seat cushion 310 is hinged with the lower end of the sliding seat B321.

[0061] In the specific implementation manner of the present invention, two support tubes 711 are arranged in parallel, the sliding rod 311, the support tube 711 and the shock absorption spring 730 are arranged in one-to-one correspondence, an arc-shaped connecting plate is fixed at the rear end of the seat cushion 310, and one end of the arc-shaped connecting plate is hinged with the lower end of the sliding seat B321 through a hinge seat.

[0062] When the seat cushion 310 is not subjected to external force, the seat cushion 310 is in an inclined state. When the seat cushion 310 is subjected to downward gravity, while compressing the shock absorption spring 730, it pushes the rotating rod 710 to rotate a certain angle, so that the upper surface of the seat cushion 310 is in a parallel state, improving the seat comfort. And when not sitting, it is in an inclined state, and water will not accumulate and impurities will not gather. When driving on a bumpy road section, the shock absorption spring 730 expands and contracts in cooperation with the damping characteristic of the damping hole 713 to achieve the shock absorption effect. Moreover, the seat cushion 310 has an inclined swing amplitude. Compared with the traditional up and down swing amplitude, this shock absorption design in the inclined direction divides the force displacement in the single up and down direction into two directions of up and down and front and back, making the swing amplitude smaller and the shock absorption effect better.

[0063] Comfort improvement: The ergonomic shape design, good shock absorption performance and adjustable functions can effectively reduce the fatigue of drivers and enhance the comfort during long - time driving.

[0064] Health protection: The correct sitting posture support and shock absorption design help reduce strain on parts such as the waist and neck, lower the risk of drivers getting occupational diseases, and protect physical health.

[0065] Improved work efficiency: A comfortable seat environment enables drivers to maintain a good state, be more focused on operations, thus improving work efficiency and operation quality.

[0066] The above are only examples of the present application and are not used to limit the protection scope of the present application. For those skilled in the art, the present application can have various changes and modifications. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application. It should be noted that similar reference numerals and letters represent similar items in the following drawings. Therefore, once an item is defined in one drawing, it does not need to be further defined and explained in subsequent drawings.
