Description

Technical Field

[0001] The utility model relates to the field of tractors, in particular to an adjustable tractor traction structure. Background Art

[0002] A tractor's towing structure refers to the device or system used by a tractor to connect and tow agricultural implements or trailers. It usually includes a series of mechanical components designed to ensure that the tractor can safely and efficiently tow various agricultural equipment such as tillage tools, seeders, sprayers, harvesters, etc.

[0003] Traditional tractor traction structures usually use a fixed-length traction device. Although this method is simple in structure, it has certain limitations in actual agricultural operations. Due to different farmland environments and operating requirements, fixed-length traction devices are often difficult to adapt to various working conditions. In particular, when different types of agricultural implements are connected, the distance between the tractor and the agricultural implement may be inappropriate. If the length is too long, it will increase the overall length of the tractor and reduce its flexibility and turning radius; if it is too short, it will affect the operating effect of the agricultural machinery and even affect the balance and safety of the tractor, thereby affecting operating efficiency.

[0004] For this reason, this patent urgently needs to provide a kind of adjustable tractor traction structure. Utility Model Content

[0007] Furthermore, it also includes a rotating seat, which is installed on the second mounting ring; a mounting block, which is rotatably mounted on the rotating seat and can rotate 360 ​​degrees; a mounting cylinder, which is arranged at the lower part of the rotating seat; and a second mounting bolt, which is arranged at the upper part of the rotating seat.

[0008] Furthermore, it also includes a screw rod, which is installed inside the mounting block; a guide sleeve, which is threadedly installed on the screw rod; a damping rod, which is slidably installed on the guide sleeve; and a shock-absorbing spring, which is sleeved on the outside of the guide sleeve.

[0009] Furthermore, a first anti-slip pad is included, and the first anti-slip pad is arranged inside the connecting hole of the damping rod.

[0010] Furthermore, a dust plug is included, which is arranged in the remaining installation hole.

[0011] Furthermore, a second anti-slip pad is included, and the second anti-slip pad is arranged inside the connecting hole of the second mounting ring.

[0012] Compared with the prior art, the utility model has the following technical effects: 1. The adjustable tractor traction structure can realize the length adjustment function through the combination of the first mounting ring, the second mounting ring, the limit guide block and the first mounting bolt. Such a design facilitates the flexible adjustment of the traction length according to actual operation requirements to ensure that the optimal working distance is maintained between the tractor and the connected agricultural implements, which not only improves the flexibility of operation but also enhances stability.

[0022] During use, the agricultural implement is connected through the second mounting ring 6 to realize the traction function of the tractor. In addition, according to actual operation requirements, the first mounting bolt 8 can be loosened first, and then the second mounting ring 6 can be pulled to extend or shorten to adjust the traction length to ensure the stability and appropriate distance between the tractor and the agricultural implement. After the adjustment is completed, the first mounting bolt 8 is re-tightened into the threaded hole 301 on the second mounting ring 6 to complete the position fixation.

[0023] Example 2: Based on Example 1, please refer to Figure 4 , also includes: a rotating base 10, the rotating base 10 is installed on the second mounting ring 6; a mounting block 9, the mounting block 9 is rotatably mounted on the rotating base 10, and the mounting block 9 can achieve 360-degree rotation; a mounting cylinder 301, the mounting cylinder 301 is arranged at the lower part of the rotating base 10; a second mounting bolt 12, the second mounting bolt 12 is arranged at the upper part of the rotating base 10, and is connected to the mounting cylinder 301 through the second mounting screw thread 301 to achieve the installation and fixation of the rotating base 10.

[0024] Before connecting the agricultural implement, the mounting block 9 and the rotating seat 10 are mounted on the second mounting ring 6 using the mounting tube 301 and the second mounting bolt 12. The 360-degree rotatable feature of the mounting block 9 facilitates flexible movement of different agricultural implements after connection.

[0025] See also Figure 5 , further comprising: a screw 13, the screw 13 being mounted inside the mounting block 9; a guide sleeve 14, the guide sleeve 14 having a thread 301 mounted on the screw 13; a damping rod 15, the damping rod 15 being slidably mounted on the guide sleeve 14, a shock-absorbing spring 16, the shock-absorbing spring 16 being sleeved on the outside of the guide sleeve 14, the two ends of the shock-absorbing spring 16 being respectively connected to the guide sleeve 14 and the damping rod 15; a first anti-slip pad 17, the first anti-slip pad 17 being arranged inside the connecting hole of the damping rod 15, for increasing the friction between the damping rod 15 and the agricultural implement.

[0026] After the mounting block 9 and the rotating seat 10 are installed, a buffer protection area can be added to the mounting block 9 by installing a guide sleeve 14 in conjunction with the screw 13. When the device is subjected to an external force, the damping rod 15 will slide along the guide sleeve 14 and compress the shock-absorbing spring 16. At this time, the shock-absorbing spring 16 acts as a buffer to absorb the external force. The buffer protection area can protect other components in the system from damage when the agricultural implement is subjected to impact or vibration, while reducing the vibration generated by the connection between the machines and improving the operation stability.
