Description

Technical Field

[0001] The utility model relates to the technical field of a spring shock-absorbing total pull rod, and more specifically, to a spring shock-absorbing total pull rod based on a tractor. Background Art

[0002] Tractors are self-propelled power machines used to pull and drive operating machinery to complete various mobile operations. They can also be used as fixed operating power. They are composed of engine, transmission, travel, steering, hydraulic suspension, power output, electrical instruments, driving control and traction systems or devices. The engine power is transmitted to the drive wheels by the transmission system to make the tractor move. In real life, the most common ones are those that use rubber belts as the medium for power transmission. Tractors are divided into agricultural, industrial and special-purpose tractors according to their functions and uses. They are divided into wheeled, crawler, boat-shaped tractors and self-propelled chassis according to their structural types. In tractors, the spring shock-absorbing master rod is one of the most important parts.

[0003] However, when the mounting joint of the existing spring shock absorber total tie rod is damaged, the spring shock absorber total tie rod is generally replaced as a whole, or the mounting joint is replaced separately when the spring shock absorber total tie rod has the function of disassembly and adjustment. However, since the spring is in direct contact with the mounting joint, the spring will fall off when the spring shock absorber total tie rod is disassembled, and the mounting joint is difficult to install due to the elastic force during installation. Utility Model Content

[0004] In order to overcome the above-mentioned defects of the prior art, an embodiment of the utility model provides a spring shock-absorbing master tie rod based on a tractor. Through the setting of a connecting mechanism, when the joint needs to be replaced, it can be achieved without changing the spring, so as to solve the problems raised in the above-mentioned background technology.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solution: a spring shock-absorbing total pull rod based on a tractor, comprising a spring body, a pull rod body is arranged inside the spring body, a mounting block is arranged on the top of the pull rod body, a first groove is provided at the bottom of the mounting block, a connecting plate is provided at the bottom of the spring body, a threaded through hole is provided inside the connecting plate, a threaded plate is provided inside the threaded through hole, the top of the threaded plate is connected to the bottom of the pull rod body, and a connecting mechanism is provided at the top of the mounting block and the bottom of the threaded plate.

[0006] In a preferred embodiment, the connection mechanism comprises a connection block, a joint is arranged on the top of the connection block, and a second groove is formed inside the joint.

[0007] In a preferred embodiment, a first washer is disposed inside the second groove, the first washer is made of rubber material, and a connecting pin is disposed on the top of the first washer.

[0008] In a preferred embodiment, the cross-sectional shape of the connecting pin is set to be T-shaped, and one end of the connecting pin passes through the joint and the connecting block in sequence and extends into the interior of the connecting block.

[0009] In a preferred embodiment, a second washer is provided on one side of the connection block, the second washer is made of rubber material, and a bolt is provided on one side of the second washer.

[0011] In a preferred embodiment, one end of the positioning pin passes through the connecting block and the connecting pin in sequence and extends into the interior of the connecting block.

[0012] In a preferred embodiment, a limiting ring is provided on the top of the connecting plate.

[0013] Technical effects and advantages of the utility model:

[0014] By setting up a connecting mechanism, the joint is installed in a way that is different from the previous way of directly contacting the spring, but is installed by avoiding contact between the connecting block and the spring. This installation method allows the joint to be replaced without changing the position of the spring. The cooperation between the connecting plate and the threaded plate allows the spring to be installed in a new way, so that the spring can still be easily replaced. The reasonable setting of the connecting mechanism makes the joint simpler and more convenient for operators to operate during installation and replacement. Through such a series of measures, the practicability of the device during use is significantly improved. BRIEF DESCRIPTION OF THE DRAWINGS
