[0025] like Figure 1 - Figure 3 As shown, a mobile coal washing equipment of the present invention includes a coal washing machine body 1, a support frame 2 and a roller assembly 3;

[0026] The frame 10 is disposed at the bottom of the coal washer body 1, and a washing tank 11 is connected to the upper end of the frame 10. The washing tank 11 serves as a container for the raw coal. A screw conveyor assembly 12 is connected to the washing tank 11. The screw conveyor assembly 12 transports the raw coal placed in the washing tank 11, and during transportation, the raw coal is cleaned by a spray assembly connected to the inner wall of the washing tank 11. A drive assembly 13 connected to the rotating shaft of the screw conveyor assembly 12 is provided on the side of the frame 10. Driven by the drive assembly 13, the screw conveyor assembly 12 rotates, causing the skewer connected to and surrounding the outer periphery of the rotating shaft to rotate together.

[0027] The driving assembly 13 also includes a corresponding reduction gear transmission structure and a motor.

[0028] The coal washer body 1 is symmetrically provided with support frames 2, and the bottom of each support frame 2 is connected to a roller assembly 3. The roller assembly 3 can facilitate the movement of the entire device and reduce transportation costs. In addition, the roller assembly 3 is provided with a wheel brake 30 to prevent the device from moving after it is positioned and in operation.

[0029] Each support frame 2 includes an upper support 20 arranged in pairs and connected to the frame body 10 , a lower support 21 sleeved on the outer periphery of the upper support 20 , and an adjustment mechanism for controlling the relative sliding of the upper support 20 and the lower support 21 .

[0030] A support frame 2 is provided at the lower part of the coal washer body 1. The upper support 20 and the lower support 21 are moved relative to each other through the action of the adjusting machine, so that the coal washer body 1 is raised or lowered to facilitate the subsequent loading of the conveyor. The height adjustment process is simple and easy.

[0031] Specifically, the adjustment mechanism includes a screw 220 and a handle 221. The ends of the screw 220 are connected to a cross frame 222. The ends of the cross frame 222 are respectively connected to the inner sides of the upper bracket 20 and the lower bracket 21. The adjustment mechanism can also adopt other structures with telescopic functions, such as a cylinder.

[0032] Since the adjustment mechanism adopts the screw 220 transmission method, compared with the existing fixed adjustment, there is no need to stop the machine and it can be operated with tools such as wrenches and jacks. It is convenient to adjust the equipment height according to work needs and use environment during the coal washing process, and the coal washing efficiency is high.

[0033] In addition, an arc-shaped rotating block 23 is provided at the end of the upper bracket 20, and the upper bracket 20 is connected to the frame body 10 via the arc-shaped rotating block 23. By providing the arc-shaped rotating block 23, the connection angle between the support frame 2 and the frame body 10 can be adjusted, so that it can be used in sites with complex and uneven ground conditions, and the connection between the support frame 2 and the frame body 10 does not have to be vertical.

[0034] In addition, since the support frames 2 are symmetrically arranged at the lower part of the coal washer body 1, each group of support frames 2 can be adjusted independently. When the height adjustment of the two groups of support frames 2 is inconsistent, the coal washer body 1 can be tilted at a certain angle as needed.

[0035] Specifically, an arc-shaped through hole 230 for a fastener to extend into is provided on the side of the arc-shaped rotating block 23, and the fastener can be a bolt.

[0036] To facilitate angle adjustment, an angle mark (not shown) is provided near the arc-shaped through hole 230 . By observing the angle mark, the angle between the upper bracket 20 and the frame body 10 at this time can be determined.

[0037] It is worth noting that the wheel used in the roller assembly 3 can be made of a material with a buffering effect such as rubber, which can reduce damage to the ground and improve mechanical stability.

[0038] The above are only embodiments of the present invention. Common knowledge such as the known specific structures and characteristics in the scheme is not described in detail here. Ordinary technicians in the relevant field are aware of all common technical knowledge in the technical field of the utility model before the application date or priority date, can obtain all existing technologies in the field, and have the ability to apply conventional experimental means before that date. Ordinary technicians in the relevant field can improve and implement this scheme based on their own abilities under the guidance of this application. Some typical known structures or methods should not become obstacles for ordinary technicians in the relevant field to implement this application. It should be pointed out that for those skilled in the art, without departing from the structure of the utility model, they can also make several variations and improvements, which should also be regarded as the scope of protection of the utility model. These will not affect the effect of the implementation of the utility model and the practicality of the patent.
