Description

Technical Field

[0001] The utility model relates to the technical field of coal mining, in particular to a system for cleaning coal gangue sticking to a warehouse wall by ultrasonic resonance. Background Art

[0002] Coal mines currently use mine cars or bucket elevators for lifting. Due to the high viscosity of the coal being transported, the coal on the mine cars or bucket elevators often sticks to the conveying channel of the unloading station, causing blockage, which seriously affects the transportation efficiency.

[0003] In order to solve the above problems, the prior art mainly uses sound waves for dredging. For example, patent application number CN202122194871.X discloses a silo leaking coal bunker acoustic energy dredging device, which connects the acoustic energy conduit 4 to the silo wall, and then connects the servo motor 2 to the external power supply through the frequency conversion control cabinet 5, and the acoustic wave generator host 1 is connected to the external power supply. The acoustic wave generator host 1 and the frequency conversion control cabinet 5 are started, and the voltage regulator tank 7 is adjusted. The compressed air enters the modulation core 3 inside the acoustic wave generator host 1 through the pipe section. The modulation core 3 is driven by the servo motor 2, and the speed of the servo motor 2 is controlled by the frequency conversion control cabinet 5. A high speed generates a high frequency of sound waves, and a low speed generates a low frequency of sound waves. The sound waves are transported to the blocked position of the silo through the acoustic energy conduit 4 to cause material vibration to achieve the purpose of dredging. In summary, the speed of the servo motor is adjusted by the frequency conversion control cabinet to achieve the purpose of changing the frequency of the sound waves. Different sound wave frequencies can cause larger amplitudes for different materials, and the dredging effect is better and more significant.

[0004] The acoustic energy dredging device in the prior art has a technical defect in actual use. The acoustic energy dredging device cannot be moved. After being fixedly installed, it can only dredge blockages within a certain range. The scope of application is relatively narrow. When encountering coal mine transfer equipment such as silos, mine cars, and elevator buckets with a large space width, it is necessary to install multiple acoustic energy dredging devices to achieve effective dredging, and the procurement cost is relatively high.

DETAILED DESCRIPTION

[0025] The embodiments of the present utility model are described in detail below with reference to the accompanying drawings.

[0028] The slide plate 30 is movably disposed between two opposite plates of the baffle 20;

[0029] Two movable plates 31 are respectively fixedly connected to the slide plate 30;

[0030] A plurality of rotating plates 52 are rotatably disposed between the two moving plates 31;

[0031] The box body 50 is fixedly connected to the rotating plate 52 and has an opening facing downward;

[0032] A box cover 51 is detachably fixedly connected to the lower end of the box body 50;

[0033] The sound wave generator 70 is fixedly connected to the box cover 51 and is located inside the box body 50;

[0034] The speaker 71 is fixedly connected to the sound outlet end of the sound wave generator 70 , and the speaker 71 slides through the side wall of the box body 50 .

[0035] This embodiment is implemented as follows:

[0036] When the present application is in use, the movement of the slide plate 30 and the movable plate 31 can drive the rotating plate 52 to move, and the rotating plate 52 can rotate between the two movable plates 31, so the rotating plate 52 can drive the box body 50 to move, and at the same time can drive the box body 50 to rotate. The movement of the box body 50 can adjust the position of the opening of the speaker 71 on the sound wave generator 70, and the rotation of the rotating plate 52 can adjust the inclination angle of the speaker 71, so that the speaker 71 can clear the blocked position in the material guide channel 10.

[0038] See also Figure 1 , 3 4. A threaded rod 40 and a fixedly arranged limiting rod 42 are rotatably arranged between two opposite side walls of the baffle 20. A driving motor 41 is fixedly connected to one side wall of the baffle 20. The output end of the driving motor 41 is fixedly connected to the threaded rod 40.
