Description

Technical Field

[0001] This utility model relates to a rubber track, specifically a rubber track for use in snow and grassland, and belongs to the field of rubber track technology. Background Technology

[0002] Currently, rubber tracks, as a type of ring-shaped belt made of rubber and metal or fiber materials, are widely used in various engineering machinery, agricultural machinery, and special equipment. They typically consist of a rubber matrix and core iron components. Core iron components are evenly distributed within the rubber matrix. The rubber matrix is ​​in direct contact with the ground, bearing the friction and impact forces during vehicle movement, while the core iron primarily serves to transmit power, guide, and provide lateral support.

[0003] In practical applications, the rubber tracks used in grassland and snow removal equipment are mostly modified from conventional engineering machinery. These conventional rubber tracks, on hard surfaces such as concrete, asphalt, or compacted soil, generate significant friction and resistance with the ground due to their tread structure, enabling stable operation. However, in special scenarios such as snow and grassland, existing rubber tracks reveal significant shortcomings. The smooth and easily deformable surface of snow, coupled with the soft texture and insufficient root support of grassland vegetation, drastically reduces the coefficient of friction between the rubber tracks and the ground. When equipment travels on these terrains, it is highly susceptible to slippage and spinning, leading not only to low operating efficiency but also potential safety hazards such as loss of control and rollover, thus reducing the stability of the equipment. Utility Model Content

[0004] The purpose of this utility model is to provide a rubber track for use on snow and grass to solve the above-mentioned problems. By setting detachable anti-slip lugs on the core iron, the anti-slip lugs will insert into the ground when traveling on snow and grass, thereby playing an anti-slip role and ensuring the stability of the equipment. At the same time, the anti-slip lugs can be disassembled, so they can be replaced individually when damaged, thereby improving the efficiency of track inspection and maintenance.

[0005] This utility model achieves the above-mentioned objective through the following technical solution: a rubber track for use in snow and grass, comprising a core iron, on which two protrusions are integrally formed, and a rubber matrix is ​​wrapped around the outside of multiple core irons. One end of each protrusion is integrally formed with a positioning protrusion, and an anti-slip lug is engaged on the positioning protrusion. A fixing bolt is provided through the anti-slip lug, and the fixing bolt is threaded to the protrusion. The anti-slip lug is provided with a stop structure.

[0006] Preferably, the positioning protrusion has an overall quadrangular prism structure, and the top of the cross-section of the positioning protrusion has a trapezoidal structure.

[0007] Preferably, the two protrusions are symmetrically distributed about the middle of the core iron, and the rubber matrix is ​​provided with multiple anti-slip grooves.

[0008] Preferably, the rubber matrix has a reinforcing layer inside, which is formed by multiple strands of steel wire rope.

[0009] Preferably, the outer side of the anti-slip lug is provided with two anti-slip recesses, and the two anti-slip recesses are symmetrically distributed about the middle of the anti-slip lug.

[0010] Preferably, the anti-slip lug has a through hole in the middle, the diameter of the through hole cross section is equal to the diameter of the middle cross section of the fixing bolt, and the diameter of the through hole cross section is smaller than the diameter of the top cross section of the fixing bolt.

[0011] Preferably, the blocking structure includes a stop block and a limiting block. One end of the anti-slip lug is engaged with the stop block. Two limiting blocks are integrally formed on both sides of the stop block. The limiting blocks are slidably connected to the anti-slip lug. A rotating shaft is rotatably connected to the stop block. One end of the rotating shaft is fixedly connected to a rotating block. A torsion spring is fixedly connected between the rotating shaft and the stop block. Two locking blocks are fixedly connected to the rotating shaft. The anti-slip lug is provided with two locking grooves. The two locking grooves are arranged in a circumferential array about the center of the anti-slip lug. One end of the locking block engages with the adjacent locking groove.

[0012] Preferably, the abutment block is provided with two sliding grooves, and the locking block slides inside the adjacent sliding grooves.

[0013] Preferably, the rotating block has multiple openings, and the multiple openings are arranged in a circular array about the center of the rotating block.

[0014] The beneficial effects of this utility model are as follows: When driving on grass or snow, multiple anti-slip lugs will insert into the ground to provide anti-slip protection and ensure the stability of the equipment. When an anti-slip lug is damaged, the fixing bolt can be unscrewed from the lug using an Allen wrench, and then pulled out from the inside of the lug. The damaged lug can then be removed from the positioning protrusion, thus achieving disassembly. Therefore, when an anti-slip lug is damaged, it only needs to be removed and replaced individually, effectively improving the efficiency of track maintenance. When installing a new anti-slip lug, the positioning protrusion engages with the anti-slip lug to position it and improve its stability after installation. After the anti-slip lug engages with the positioning protrusion, the fixing bolt can be passed through the lug and tightened. Finally, the abutment structure blocks the hexagonal groove at the bolt end, preventing mud and sand from clogging the groove and facilitating bolt installation and removal.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figures 1-7 As shown, a rubber track for use on snow and grass includes a core iron 1. Two protrusions 2 are integrally formed on the core iron 1. A rubber matrix 9 is wrapped around the outside of multiple core irons 1. A positioning protrusion 3 is integrally formed at one end of each protrusion 2. An anti-slip lug 4 is engaged on the positioning protrusion 3. A fixing bolt 5 is provided through the anti-slip lug 4. The fixing bolt 5 is threaded to the protrusion 2. A blocking structure 6 is provided on the anti-slip lug 4.

[0025] As a technical optimization of this utility model, the positioning protrusion 3 is generally in the shape of a quadrangular prism, which can prevent rotation between the anti-slip lug 4 and the positioning protrusion 3. The top of the cross section of the positioning protrusion 3 is in the shape of a trapezoid, which can play a guiding role when the positioning protrusion 3 and the anti-slip lug 4 are engaged.

[0026] As a technical optimization of this utility model, the two protruding pillars 2 are symmetrically distributed about the middle of the core iron 1, and the rubber matrix 9 is provided with multiple anti-slip grooves 11. The stability of the equipment during operation can be improved by the multiple anti-slip grooves 11.

[0027] As a technical optimization of this utility model, the rubber matrix 9 is provided with a reinforcing layer 10 inside, which can improve the overall strength of the rubber track. The reinforcing layer 10 is formed by multiple strands of steel wire rope.

[0028] As a technical optimization of this utility model, the outer side of the anti-slip lug 4 is provided with two anti-slip recesses 8. The two anti-slip recesses 8 are symmetrically distributed about the middle of the anti-slip lug 4. When pulling out the anti-slip lug 4, the two anti-slip recesses 8 can prevent the hand from slipping, thereby facilitating the disassembly of the anti-slip lug 4.

[0029] As a technical optimization of this utility model, the anti-slip lug 4 has a through hole 7 in the middle. The diameter of the cross-section of the through hole 7 is equal to the diameter of the cross-section of the middle part of the fixing bolt 5. Therefore, the outer side of the fixing bolt 5 can fit with the inner wall of the anti-slip lug 4, thereby improving the stability of the anti-slip lug 4 after installation. The diameter of the cross-section of the through hole 7 is smaller than the diameter of the top cross-section of the fixing bolt 5. Therefore, when the fixing bolt 5 and the protrusion 2 are threaded together, the anti-slip lug 4 can be fixed.

[0030] As a technical optimization of this utility model, the blocking structure 6 includes a stop block 601 and a limiting block 602. One end of the anti-slip lug 4 is engaged with the stop block 601. Two limiting blocks 602 are integrally formed on both sides of the stop block 601. The limiting blocks 602 can position the stop block 601 during installation, thereby facilitating the insertion of the locking block 607 into the slot 609. The limiting blocks 602 and the anti-slip lug 4 are slidably connected. A rotating shaft 605 is rotatably connected to the stop block 601, and a rotating block 603 is fixedly connected to one end of the rotating shaft 605. A torsion spring 606 is fixedly connected between the rotating shaft 605 and the abutment block 601. Under the action of the torsion spring 606, the rotating shaft 605 can rotate automatically, causing the two locking blocks 607 to move to the inside of the locking slot 609. Two locking blocks 607 are fixedly connected to the rotating shaft 605. The anti-slip lug 4 is provided with two locking slots 609. The two locking slots 609 are arranged in a circular array about the center of the anti-slip lug 4. One end of the locking block 607 engages with the adjacent locking slot 609. The abutment block 601 can be fixed by the engagement between the locking block 607 and the locking slot 609.

[0031] As a technical optimization of this utility model, the abutment 601 is provided with two sliding grooves 608. The sliding grooves 608 can limit the movement range of the locking block 607, and the locking block 607 slides inside the adjacent sliding grooves 608.

[0032] As a technical optimization of this utility model, the rotating block 603 is provided with multiple openings 604. By inserting a flathead screwdriver into the opening 604, the rotating block 603 can be easily rotated. The multiple openings 604 are arranged in a circular array about the center of the rotating block 603.

[0033] In use, when driving on grass or snow, multiple anti-slip lugs 4 insert into the ground to prevent slippage and ensure the stability of the equipment. When the anti-slip lugs 4 are damaged, a flathead screwdriver can be inserted into the opening 604, and then the rotating block 603 can be rotated. The rotation of the rotating block 603 will drive the rotating shaft 605 to rotate, which in turn will cause the two locking blocks 607 to move within the two locking slots 609 respectively. The torsion spring 606 will undergo elastic deformation, and with the movement of the locking blocks 607, one of the locking blocks will... When the anti-slip lug 4 comes into contact with the stop block 601, the rotating block 603 cannot be rotated. Simultaneously, the locking block 607 is located at the outlet outside the slot 609, so the anti-slip lug 4 will not obstruct the locking block 607 when the stop block 601 is moved. Then, the stop block 601 can be moved so that it no longer obstructs the fixing bolt 5. Next, the fixing bolt 5 can be unscrewed from the protrusion 2 using an Allen wrench, and then pulled out from the inside of the anti-slip lug 4. The damaged anti-slip lug 4 can then be removed from the positioning protrusion 3, thus achieving the disassembly of the anti-slip lug 4. Therefore, when the anti-slip lug 4 is damaged, it only needs to be removed and replaced individually, which effectively improves the efficiency of track maintenance. When installing a new anti-slip lug 4, the positioning protrusion 3 can engage with the anti-slip lug 4 to achieve positioning of the anti-slip lug 4, and also improve the stability of the anti-slip lug 4 after installation. After the anti-slip lug 4 engages with the positioning protrusion 3, the fixing bolt 5 can be passed through the anti-slip lug 4 and tightened. Finally, the abutment block 601 is inserted into the end of the anti-slip lug 4, and by setting two The limiting block 602 can prevent the abutment block 601 and the anti-slip lug 4 from rotating. When the abutment block 601 and the end of the fixing bolt 5 come into contact, the torsion spring 606 will reset and cause the rotating shaft 605 to rotate. The rotation of the rotating shaft 605 will cause the locking block 607 to move to the inside of the locking groove 609. At this time, the abutment block 601 cannot move. The abutment block 601 can not only block the hexagonal groove at the end of the fixing bolt 5 to prevent mud and sand from blocking it, but also block the end of the fixing bolt 5 to prevent the fixing bolt 5 from loosening.
