[0002] The excavator roller is an important part of the excavator, mainly responsible for supporting and guiding the walking of the excavator track. The roller reduces the friction between the track and the ground through its rolling motion, enabling the excavator to move easily on various terrains. When the excavator roller is in transmission, a certain amount of heat is generated, which may cause damage to it. Therefore, it is necessary to dissipate heat from the excavator roller.

Therefore, those skilled in the art provide a heat dissipation structure for excavator rollers to solve the problems raised in the above background art. Summary of the Utility Model

[0019] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the scope of protection of the present utility model.

[0020] Please refer to Figures 1-4 , the present utility model provides a heat dissipation structure technical solution for an excavator roller: including: a connecting plate 4 and a mounting plate 41 fixed at the end position on the upper surface of the connecting plate 4. A connecting rod 5 penetrates through the lower surface of the mounting plate 41. A first nut 51 is threadedly connected to the upper surface of the connecting plate 4 on the outer side of the connecting rod 5, and a second nut 54 is threadedly connected to the lower surface of the connecting plate 4 on the outer side of the connecting rod 5. The lower end of the connecting rod 5 is further connected to a heat dissipation box 1. Heat dissipation fans 3 are symmetrically arranged on the rear surface of the heat dissipation box 1, and a filter screen 21 is arranged inside the heat dissipation box 1. A sealing plate 2 is installed on the front surface of the heat dissipation box 1 on the front surface of the filter screen 21. This setting uses the filter screen 21 to filter the dust entering the interior of the heat dissipation box 1, which can improve the service life of the heat dissipation fans 3, and the position of the heat dissipation box 1 can be adjusted by sliding the connecting plate 4 on the outer side of the connecting rod 5, so as to achieve the purpose of efficiently dissipating heat from the excavator roller.

[0021] As Figure 1 shown, the connecting plate 4 and the mounting plate 41 are arranged in an "L" shape. Bolts are symmetrically arranged on the outer side of the mounting plate 41. This setting uses the bolts to install the mounting plate 41 on the outer wall of the excavator, so as to achieve the purpose of dissipating heat from the roller subsequently.

[0022] As Figure 3 and Figure 4 shown, a first gasket 52 is sleeved on the outer side of the connecting rod 5 below the first nut 51, and a second gasket 53 is also sleeved on the outer side of the connecting rod 5 above the second nut 54. The first nut 51 and the second nut 54 have the same radius, and the first gasket 52 and the second gasket 53 are of the same size. This setting uses the first nut 51 and the second nut 54 to lock and position the connecting rod 5, and the first gasket 52 and the second gasket 53 can protect the first nut 51 and the second nut 54.

[0023] As Figure 1 shown, an air inlet hole 11 is opened on one side of the heat dissipation box 1. Two groups of heat dissipation fans 3 are symmetrically arranged on the other side of the heat dissipation box 1. This setting uses the air inlet hole 11 to suck external air into the interior of the heat dissipation box 1 for filtering treatment when the heat dissipation fans 3 are working, and the two groups of heat dissipation fans 3 can efficiently dissipate heat from the excavator roller.

[0024] As shown Figure 2 in the figure, positioning pins 23 are symmetrically arranged on the rear surface of the sealing plate 2, and positioning holes 22 that are engaged with the positioning pins 23 are formed on the front surface of the heat dissipation box 1. By embedding the positioning pins 23 into the positioning holes 22, the positioning and installation of the sealing plate 2 can be realized, ensuring the sealing of the connection.

[0025] The working principle of the present utility model is as follows: When the heat dissipation structure of the excavator roller of the present utility model is in use, first, the mounting plate 41 is installed on the side of the excavator through bolts. After installation, by rotating the first nut 51 and the second nut 54 outside the connecting rod 5, the connecting rod 5 can slide inside the connecting plate 4 to adjust the height of the heat dissipation box 1. After adjustment, the first nut 51 and the second nut 54 can be rotated again, so that the distance between the first nut 51 and the second nut 54 is reduced to fix the connecting rod 5. After fixation, the heat dissipation fan 3 can be aligned with the excavator roller. When heat dissipation is required, by starting the heat dissipation fan 3, external air can enter the heat dissipation box 1 through the air inlet hole 11. After entering, the dust in the air will be filtered by the filter screen 21, which can improve the service life of the heat dissipation fan 3. When the filter screen 21 inside the heat dissipation box 1 needs to be replaced, at this time, only need to pull the sealing plate 2 forward so that the positioning pin 23 is separated from the positioning hole 22, which can facilitate the extraction of the filter screen 21 from the inside of the heat dissipation box 1 to achieve the purpose of replacement and cleaning.

[0026] The above is only the preferred embodiment of the present utility model. It should be noted that for those of ordinary skill in the art in this technical field, without departing from the principle of the present utility model, several improvements and refinements can still be made, and these improvements and refinements should also be regarded as the protection scope of the present utility model. The structures, devices, and operation methods not specifically described and explained in the present utility model, without special instructions and limitations, are implemented according to the conventional means in this field.
