[0021] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, a coal material mixing and stirring device includes a belt conveyor 1, an auxiliary device 2, a stirring device 3, a driving device 4, and a workbench 5;

The bracket 2.1 is composed of two upright posts 2.1.1 and a horizontal plate 2.1.2 fixed between the two upright posts 2.1.1. The two upright posts 2.1.1 are placed on both sides of the belt conveyor 1, the horizontal plate 2.1.2 is placed above the top belt of the belt conveyor 1, the rotating shaft 2.2 is placed above the horizontal plate 2.1.2, the rotating shaft 2.2 is designed to be parallel to the horizontal plate 2.1.2, and the rotating shaft 2.2 is arranged to be parallel to the horizontal plate 2.1.2. One end is rotatably connected with a column 2.1.1, the other end of the rotating shaft 2.2 is rotatably inserted into another column 2.1.1, a cam 2.3 is sleeved and fixed on the rotating shaft 2.2, a vertical rod 2.4 is slidably inserted into the horizontal plate 2.1.2, the bottom end of the vertical rod 2.4 is fixed to the rake claw 2.5, the top end of the vertical rod 2.4 is fixed to the bottom plate 2.6, a spring 2.8 is sleeved on the vertical rod 2.4 between the horizontal plate 2.1.2 and the bottom plate 2.6, a roller 2.7 is rotatably installed on the top of the bottom plate 2.6, and the wheel surface of the cam 2.3 is in rolling contact with the wheel surface of the roller 2.7;

[0023] The rotating shaft 2.2 can drive the cam 2.3 to rotate, and the elastic force of the spring 2.8 drives the vertical rod 2.4 to push upward, and the wheel surface of the roller 2.7 is close to the wheel surface of the cam 2.3, and the cam 2.3 and the roller 2.7 roll. Because the cam 2.3 is an eccentric circle, the wheel surface of the cam 2.3 far from the center of the circle pushes the vertical rod 2.4 and the rake claw 2.5 to descend, and the spring 2.8 drives the vertical rod 2.4 to rise, and the rake claw 2.5 is driven by the vertical rod 2.4 to reciprocate and rise and fall. The auxiliary device 2 is installed at the front end of the nozzle. Before spraying water, the rake claw 2.5 frequently disrupts the surface of the coal and cuts open the inside of the coal, which is conducive to spraying water on more surfaces of the coal and inside the coal.

[0024] The stirring device 3 comprises a rectangular shell 3.1, one side of the rectangular shell 3.1 is provided with an opening 3.2, the bottom of the rectangular shell 3.1 is provided with an outlet 3.3, the tail end of the belt conveyor 1 extends into the rectangular shell 3.1 through the opening 3.2, and the coal falls from the tail end of the belt conveyor 1 into the outlet 3.3 of the rectangular shell 3.1, and an active roller 3.4 and a passive roller 3.5 are respectively provided above and below the rectangular shell 3.1, and blades 3.6 are fixed on the surfaces of the active roller 3.4 and the passive roller 3.5, the active roller 3.4 is placed between the side wall of the rectangular shell 3.1 and the tail end of the belt conveyor 1, and the passive roller 3.5 is placed below the active roller 3.4 and the tail end of the belt conveyor 1, and a baffle 3.7 fixed to the edge of the outlet 3.3 is provided on one side of the passive roller 3.5, and the baffle 3.7 prevents the coal from leaking out;

[0025] A brush 3.8 is fixed on the top of the baffle 3.7. The brush 3.8 contacts the belt at the bottom of the belt conveyor 1. The brush 3.8 prevents the coal from leaking out and can also scrape off the sticky coal on the belt at the bottom of the belt conveyor 1 to a certain extent.

[0026] One end of the cylinder shaft of the active roller 3.4 is rotatably connected to the inner wall of the rectangular shell 3.1, and the other end of the cylinder shaft of the active roller 3.4 is rotatably inserted into the side wall of the rectangular shell 3.1. The cylinder shafts of the passive roller 3.5 are all rotatably connected to the inner wall of the rectangular shell 3.1.

[0027] The coal falls from the tail end of the belt conveyor 1 and is first broken up by the blades 3.6 of the rotating active roller 3.4. Figure 2 As shown, the counterclockwise rotation is conducive to the coal material colliding with the side wall of the rectangular shell 3.1, and being beaten more loosely. Then the coal material hits the passive roller 3.5. The passive roller 3.5 rotates after being impacted by the coal material, and the coal material is scattered, so that when the coal material falls into the inlet 3.3, it presents a scattered and mixed effect.

[0028] The driving device 4 is fixed on the workbench 5, and comprises a motor 4.1 and a reducer 4.2.

[0029] The motor 4.1 and the reducer 4.2 drive the rotating shaft 2.2 and the cam 2.3 to rotate, and drive the active roller 3.4 to rotate.

[0030] Working principle: In this embodiment, the attached Figure 2 The motor 4.1 and the reducer 4.2 drive the rotating shaft 2.2 and the cam 2.3 to rotate counterclockwise, and drive the active roller 3.4 to rotate counterclockwise. When the coal is transported by the belt conveyor 1, the cam 2.3 drives the vertical rod 2.4 to rise and fall back and forth. Before spraying water, the rake claws 2.5 frequently disrupt the surface of the coal and cut open the inside of the coal, which is conducive to spraying water on more surfaces of the coal and inside the coal. The coal falls from the tail end of the belt conveyor 1 into the outlet 3.3 of the rectangular shell 3.1. During the process, the coal is first broken up by the blades 3.6 of the active roller 3.4, and the coal collides with the side wall of the rectangular shell 3.1, and is broken up more. Then, the coal hits the passive roller 3.5. After being impacted by the coal, the passive roller 3.5 rotates to scatter the coal. After being broken up and mixed, the coal falls into the inlet 3.3.

[0031] Before the coal is sprayed with water, the present application can utilize the lifting and lowering of the rake claws 2.5 and the angle of the belt conveyor to disrupt the surface of the coal, which is conducive to spraying water on more surfaces of the coal and inside the coal. Later, during the falling process of the coal, the actively rotating active roller 3.4 and the passively rotating passive roller 3.5 are utilized to scatter the coal, so that the coal is scattered and mixed, and the water and the coal are mixed together.

[0032] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
