Description

Technical Field

[0001] The invention relates to the technical field of excavator track cleaning, in particular to an auxiliary device for cleaning soil blocks from an excavator track. Background Art

[0002] The crawler is the key to the movement of the excavator. The wheel belt of the excavator is called the crawler. The crawler of the excavator is usually composed of many steel links and connecting plates. The crawler links of the excavator are connected by hinges, and there are some rubber or metal gears to enhance friction and traction. This design enables the excavator to move and work on various terrains.

[0003] Excavators are widely used, but at the same time, it is a common problem that the tracks of excavators are often stuck by hard objects such as stones when moving, causing power failure of the excavator. Gravel often appears in the working environment of the excavator, so stones are often stuck in the tracks during the movement of the excavator. Because the stones that can be stuck in the gaps in the tracks are relatively tight, stones stuck in the tracks will affect the movement of the excavator, and the stones in the tracks will be squeezed and bounced when the tracks touch the ground, which will increase the danger of the excavator during work. When the staff manually cleans it, it is not only difficult to clean it, but also time-consuming and labor-intensive, affecting the excavation efficiency of the excavator. In order to prevent the excavator from being caused by track failure, it is necessary to provide an excavator track clod cleaning auxiliary device to solve the above problems.

Through the movement of the baffle, soil blocks can be prevented from splashing into the crawler, reducing the situation of excavator failure caused by bumps splashing into the crawler.

[0019] 3. The excavator track soil block cleaning auxiliary device, through the coordinated use of steel plates, T-bars and steel brush wires in the steel brush assembly, allows the soil blocks stuck in the track gap during the movement of the track to be brushed off by the steel brush, preventing the soil blocks from being stuck in the track gap and causing the excavator to be unable to move normally. When the excavator moves, the soil blocks stuck in the track gap move to the surface, and the track and the ground generate mutual force, which will cause the stones to be squeezed and bounced off, causing safety hazards.

[0037] Working process and principle:

[0038] When the crawler 2 of the excavator starts to move, the machine body 1 drives the first power rod 11 and the second power rod 12 to rotate. The first power rod 11 drives the first transmission belt 511 on the outer wall of the third groove 510 to transmit during the rotation process. The first transmission belt 511 drives the groove plate 59 to rotate. During the rotation of the groove plate 59, the circular groove disc 53 is driven to rotate. During the rotation of the circular groove disc 53, the concave column 52 is driven to rotate in the first groove 42 at the top of the fixed block 41. When the circular groove disc 53 passes through the outer notch of the arc wheel 45 during the rotation process, the hollow tube 55 in the second groove 54 of the circular groove disc 53 will rotate synchronously. When the convex block 57 passes through the outer notch of the arc wheel 45, the convex block 57 moving inside the hollow tube 55 is quickly ejected outward from the hollow tube 55 under the elastic extension action of the first spring 56. Because the first power rod 11 rotates synchronously with the crawler 2, when the convex block 57 is ejected, the stone in the gap on the outer surface of the crawler 2 will be ejected.

[0039] When the convex block 57 pops out, the circular groove disk 53 continues to rotate, because the arc-shaped groove 58 on the outer surface of the convex block 57 is slidably connected with the convex block 58 on the outer wall of the arc wheel 45, and then during the rotation of the convex block 57, it will move toward the circular groove disk 53 under the action of the convex block 45. At this time, one end of the first spring 56 is squeezed by the convex block 57. When the convex block 57 moves into the hollow tube 55, the first spring 56 is squeezed by the convex block 57 and the hollow tube 55. The first spring 56 is in a stressed state in the hollow tube 55. At this time, the convex block 57 moves into the hollow tube 55 and the top is resisted by the convex block on the outside of the arc wheel 45 until it moves to the notch on the outside of the arc wheel 45 and performs the next movement to clean the crawler 2, thereby achieving the goal that during the operation of the crawler 2, the convex block will move in the gap of the crawler 2 to prevent the gap of the crawler 2 from being stuck by hard objects such as stones, causing problems such as failure of the excavator power system.

[0040] When the machine body 1 drives the first power rod 11 and the second power rod 12 to rotate, the first power rod 11 and the second power rod 12 drive the crawler 2 to rotate. When the crawler 2 passes the bottom of the steel brush wire 73, the soil blocks knocked down or scattered by the striking component 5 can be cleaned up again by the steel brush wire 73, so that the soil blocks stuck in the gap of the crawler 2 during the movement of the crawler 2 can be brushed off by the steel brush, preventing the soil blocks from being stuck in the gap of the crawler 2, causing the excavator to be unable to move normally, or when the soil blocks stuck in the gap of the crawler 2 move to the surface when the excavator moves, the crawler 2 and the ground generate a mutual force, which will cause the stones to be squeezed and bounced, causing safety hazards.

[0041] At the same time, the second power rod 12 drives the first rotating rod 62 to rotate through the second transmission belt 63 on the outer wall of the fourth groove 61 during the rotation process. Because the first rotating rod 62 is meshed with the side of the second rotating rod 64 away from the body 1, the second rotating rod 64 is driven to rotate during the rotation of the first rotating rod 62. At the same time, because the gear on the other side of the second rotating rod 64 is meshed with the internal gear of the slide plate 65, the slide plate 65 is driven to reciprocate during the rotation of the second rotating rod 64. The slide plate 65 drives the baffle plate 67 to move through the groove block 66. The movement of the baffle plate 67 can push out the soil blocks inside the crawler 2. When the crawler 2 of the excavator is working, if the soil blocks splash into the crawler 2, it may cause the crawler 2 to malfunction, resulting in a decrease in working efficiency. The movement of the baffle plate 67 can prevent the soil blocks from splashing into the crawler 2, thereby reducing the situation where the excavator malfunctions due to the protrusions splashing into the crawler 2.
