Description

Technical Field

[0001] This utility model relates to the field of bulldozers, and in particular to a structure for preventing the dust ring of a tensioning mechanism for bulldozers from falling off. Background Technology

[0002] A bulldozer is a piece of equipment used for bulldozing and leveling soil. It has wide applications in various engineering construction fields and is considered a pre-construction work equipment. The working environment for foundation work is often harsh. During normal operation, the springs in the tensioning mechanism automatically expand and contract under resistance, causing the tensioning cylinder to move back and forth within the tensioning box. To prevent dust, dirt, and other foreign objects from entering the tensioning box, dust seals are usually installed. However, during prolonged expansion and contraction of the tensioning cylinder and under vibration, the dust seals may shift or even fall off, allowing dust, dirt, and other foreign objects to enter the box and affect the bulldozer's normal operation. Replacing the dust seals and cleaning foreign objects from the tensioning mechanism requires disassembling the tracks. Disassembling the tracks requires specialized equipment and tools. In the field or in general repair shops, the lack of specialized equipment makes it impossible to properly disassemble the tracks, severely impacting repair time, preventing the bulldozer from being quickly restored to normal operation, prolonging the construction period, and increasing user costs.

[0003] Currently, most bulldozer tensioning mechanisms on the market use dustproof rings to prevent dust, mud, and other foreign objects from entering the tensioning box. However, the dustproof rings may move or fall off, affecting the normal operation of the bulldozer.

[0004] Therefore, it is necessary to develop a dustproof ring anti-detachment structure to overcome the problems of existing technologies. Summary of the Invention

[0005] Purpose of the utility model: In view of the shortcomings and defects of the existing technology, this utility model provides a structure for preventing the dust ring from falling off in the tensioning mechanism of a bulldozer, which effectively prevents the dust ring from falling off.

[0006] Technical Solution: This utility model discloses a dustproof ring anti-detachment structure for a tensioning mechanism of a bulldozer, characterized in that it includes a tensioning cylinder, a baffle, a dustproof ring, a tensioning housing, a spring, and a guide seat; one end of the spring is installed inside the tensioning cylinder, and the other end of the spring contacts one end of the guide seat, while the other end of the guide seat contacts the end face of the tensioning housing for limiting; the tensioning cylinder is installed inside the tensioning housing, and the outer diameter of the tensioning cylinder and the inner diameter of the tensioning housing are sealed by the dustproof ring, with a baffle provided on the outside of the dustproof ring.

[0007] The baffle is fixed to the end face of the tensioning box.

[0008] The baffle is provided with a boss.

[0009] The boss is in direct contact with the outer side of the dustproof ring or has a gap of less than 2mm.

[0010] The baffle is semi-circular, circular, or fan-shaped.

[0011] Its beneficial effects: Compared with the prior art, the present invention has the following significant advantages: The present invention effectively prevents the dust ring from falling off. Attached Figure Description

[0017] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0018] This utility model discloses a dustproof ring anti-detachment structure for a bulldozer tensioning mechanism, comprising a tensioning cylinder 1, a baffle 2, a dustproof ring 3, a tensioning housing 4, a spring 5, and a guide seat 6. One end of the spring 5 is installed inside the tensioning cylinder 1, and the other end of the spring 5 contacts one end of the guide seat 6. The other end of the guide seat 6 contacts the end face of the tensioning housing 4 for limiting its position. The tensioning cylinder 1 is installed inside the tensioning housing 4, and the outer diameter of the tensioning cylinder 1 and the inner diameter of the tensioning housing 4 are sealed by the dustproof ring 3 to prevent dust, dirt, and other foreign objects from entering the tensioning housing 4. A baffle 2 is provided on the outer side of the dustproof ring 3. The baffle 2 is fixed to the end face of the tensioning housing 4. The baffle 2 has a boss 21. The boss 21 is in direct contact with the outer side of the dustproof ring 3 or has a gap of less than 2mm to prevent the dustproof ring 3 from moving or detaching. The baffle 2 can be semi-circular, circular, or fan-shaped.

[0019] During normal operation of the bulldozer, when the spring 5 in the tensioning mechanism automatically expands and contracts due to resistance, the tensioning cylinder 1 reciprocates within the tensioning housing 4. The dustproof ring 3, which acts as a seal between the tensioning cylinder 1 and the tensioning housing 4, is moved by lateral thrust. When the thrust on the dustproof ring 3 is sufficiently large, it begins to move, allowing dust, dirt, and other foreign matter to enter the tensioning housing 4. After prolonged operation, the dustproof ring 3 may detach, causing seal failure and preventing the bulldozer from operating normally. To prevent the dustproof ring 3 from moving, this invention adds a baffle 2 to the outside of the dustproof ring 3. The protrusion 21 on the baffle 2 directly contacts the outside of the dustproof ring 3 or leaves a gap of less than 2mm, thus blocking the dustproof ring 3. When the dustproof ring 3 begins to move under force, the baffle 2 can prevent the dustproof ring 3 from moving or falling off, preventing dust, mud and other foreign objects from entering the tensioning box 4, ensuring the normal operation of the bulldozer, guaranteeing the construction period, and reducing user operating costs. It has broad application prospects and good economic benefits.
