Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of tractors, and in particular to a shock absorption mechanism for tractors. Background Technology
[0002] A tractor is a self-propelled power unit used to traction and drive construction machinery to complete various mobile tasks, and can also be used for stationary work. It consists of an engine, transmission, running gear, steering, hydraulic suspension, power output, electrical instruments, driving controls, and traction systems or devices. Engine power is transmitted to the drive wheels through the transmission system, enabling the tractor to move. In tractor manufacturing, to meet the needs of some field operations and transportation, and to reduce impact losses to tractor components caused by vibration, tractor shock absorption devices are often added. For example, a tractor shock absorption device proposed in existing technology announcement number CN201021090Y includes the tractor's rear wheels and rear axle half-shaft. A leaf spring assembly is installed on the rear axle half-shaft between the rear wheels, and both ends of the leaf spring assembly are connected to lugs mounted on a bracket. However, its shock absorption effect is relatively poor. Since most tractors operate in field environments, resulting in significant vibration, this vibration, when transmitted to the seat, can cause shaking for the operator, easily affecting their normal operation. Utility Model Content
[0003] To solve the above-mentioned technical problems, this utility model provides a shock-absorbing mechanism for a tractor that allows for easy adjustment of the seating position according to operating habits, reduces vibrations caused by the tractor, makes the seat more stable, and makes operation more convenient for the operator.
[0004] This utility model discloses a shock absorption mechanism for a tractor, comprising a base, a fixing cylinder, a position adjustment component, a shock absorption buffer component, and a seating component. The base has fixing holes at its four corners. The position adjustment component is installed on the top of the base, the fixing cylinder is installed at the output end of the position adjustment component, the shock absorption buffer component is installed inside the fixing cylinder, and the seating component is installed on top of the shock absorption buffer component. In use, the base is installed on the tractor through the fixing holes. The position adjustment component can adjust the position of the seating component to accommodate drivers with different operating habits. When the tractor chassis vibrates, the shock absorption buffer component provides initial shock absorption, and the seating component further reduces the vibration from the tractor, thereby reducing the transmission of vibration energy from the mounting plate to the seat, making the seat more stable and the operator more convenient.
[0005] Preferably, the position adjustment assembly includes two slide rails, two limit baffles, two sliders, a mounting plate, and a limit component. The two slide rails are fixedly installed on the front and rear sides of the top of the base, and the limit baffles are fixedly installed on the left and right ends of the two slide rails. The sliders are slidably installed on the slide rails, and the mounting plate is installed on the top of the two sliders. The bottom of the fixed cylinder is installed on the top of the mounting plate. Through the cooperation of the sliders and slide rails, the mounting plate can be moved on the base to adjust the position of the fixed cylinder, which is convenient for drivers with different operating habits and improves practicality.
[0006] Preferably, the limiting assembly includes a connecting seat, a pressure arm, a limiting tooth, a spring, and a rack. The connecting seat is installed at the bottom left end of the mounting plate, the middle of the pressure arm is rotatably installed below the connecting seat, the right end of the pressure arm is equipped with a limiting tooth, the top of the limiting tooth is connected to a spring, the top of the spring is connected to the bottom end of the mounting plate, and the rack is installed on the top of the base between the two slide rails. When the position of the mounting plate needs to be adjusted, the left end of the pressure arm is pressed, causing the limiting tooth at the right end of the pressure arm to move upward and compress the spring, which allows the mounting plate to move. After moving to the working position, the pressure arm is released, and the spring pushes the limiting tooth downward to cooperate with the rack, limiting the mounting plate and ensuring stability.
[0007] Preferably, the shock absorption assembly includes a telescopic cylinder, a buffer plate, multiple buffers, multiple shock-absorbing springs, an airbag, and a telescopic column. The telescopic cylinder is slidably mounted on top of the fixed cylinder, and the telescopic column is slidably and sealed inside the telescopic cylinder. Buffer gas is installed inside the telescopic cylinder. A buffer plate is fixedly mounted at the bottom of the telescopic cylinder, and multiple buffers are mounted on top of the buffer plate. The tops of the buffers are connected to the top of the interior of the fixed cylinder. Shock-absorbing springs are fitted onto the outer walls of the buffers, with their bottoms connected to the buffer plate and their tops connected to the top of the fixed cylinder. The airbag is mounted at the bottom of the fixed cylinder, with its top contacting the bottom of the buffer plate. When the driver is seated, pressing down on the telescopic column compresses the buffer gas, providing initial shock absorption and improving driver comfort. When the tractor chassis vibrates, the telescopic cylinder moves downward, pulling down the buffers and shock-absorbing springs via the buffer plate. Combined with the airbag, this further reduces the vibrations from the tractor, thereby reducing the transmission of vibration energy from the mounting plate to the seat, making the seat more stable and the operator more convenient.

The seat board is fixedly installed on the top of the telescopic column, the backrest is installed on the right end of the seat board, the backrest foam is installed on the lower part of the left side wall of the backrest, and the foam seat cushion is installed on the top of the seat board. The seat board supports the driver, the foam seat cushion increases the comfort of riding, and the backrest and backrest foam support the driver's back, reducing driver fatigue.
[0009] Preferably, the device also includes a lifting sleeve, multiple guide sliders, two fixed plates, and multiple guide posts. The upper part of the lifting sleeve is fixedly installed on the top of the telescopic cylinder, and the lower part of the lifting sleeve is fitted onto the outside of the fixed cylinder. A guide slider is fixedly installed on the inner wall of the bottom of the lifting sleeve. Multiple guide grooves matching the guide sliders are opened on the outer wall of the fixed cylinder, and the guide sliders are slidably installed in the guide grooves. The two fixed plates are fixedly installed on the left and right side walls of the lifting sleeve. The multiple guide posts are slidably installed on the fixed plates, and the tops of the guide posts are connected to the bottom of the seat plate. After the driver sits on the seat plate, he pushes the guide posts to slide on the fixed plates to support and guide the seat plate and ensure stability. When the telescopic cylinder moves, it drives the lifting sleeve to slide on the outer wall of the fixed cylinder and drives the guide sliders to move in the guide grooves to guide and limit the telescopic cylinder.
