Description

Technical Field

[0001] This utility model relates to the field of coal mine tunnel engineering technology, specifically to a water spraying dust suppression device. Background Technology

[0002] In coal conveyor roadways, to better reduce dust and provide a good working environment for employees, the currently used automatic sprinkler system employs an external control system, such as a compressed air or power supply, to control the sprinkler system. External sensors and control boxes are used to synchronize the system with the conveyor belt. Because this is a coal mine roadway project, it is essential to ensure no explosion-proof operation; therefore, the control box and other equipment must be explosion-proof, resulting in high investment costs and stringent installation requirements.

Attached Figure Description

[0016] Figure 1 This is a structural schematic diagram of an embodiment of the present utility model. Detailed Implementation

[0017] To facilitate understanding of the technical solution of this utility model by those skilled in the art, the technical solution of this utility model will now be further described in conjunction with the accompanying drawings.

[0018] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection, an electrical connection, or a communication connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0019] In this application, unless otherwise expressly specified and limited, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, "multiple" means two or more, unless otherwise expressly and specifically limited.

[0020] See Figure 1 This embodiment discloses a water spraying dust suppression device, including a spray frame 1, a spray structure 2, a water gun 3, a connecting rod 4, a transmission frame 5, a transmission roller 6, and a counterweight 7.

[0021] The spray frame 1 is fixed on the conveyor belt and is set perpendicular to the conveying direction of the conveyor belt 8. The spray frame 1 is fixed with a spray mechanism 2 and a water gun 3. The spray mechanism 2 includes a spray hose 21, a spray pipe 22 and a nozzle 23. The spray hose 21 is connected to the input end of the water gun 3 to provide a water source for the water spraying dust suppression device. The input end of the spray pipe 22, which is welded and fixed on the spray frame 1, is connected to the output end of the water gun 3. Multiple nozzles 23 are provided on the spray pipe 22.

[0022] In this embodiment, the transmission frame 5 is triangular in shape, and one corner of the transmission frame 5 is connected to the handle 31 of the water gun 3 via a connecting rod 4. The transmission roller 6 is rotatably positioned between the two corners of the handle 31 away from the water gun 3. The counterweight 7 is positioned on the transmission frame 5 above the transmission roller 6.

[0023] The working principle of this embodiment is as follows: When the conveyor belt 8 in Figure 1 moves to the right, the counterweight 7 is placed on the transmission frame 5 above the transmission idler 6. Under the action of gravity, the transmission frame 5 descends, causing the transmission idler 6 to roll on the conveyor belt 8. The transmission idler 6 runs by relying on the friction between itself and the conveyor belt 8. Since the conveyor belt 8 moves to the right, the transmission idler 6 has a force to the right, which causes the transmission frame 5 to drive the handle 31 to move to the right, opening the water gun 3 and causing the nozzle 23 in the spray structure 2 to spray water, thus completing the dust suppression of the conveyor belt 8.

[0024] In this embodiment, the water spraying dust suppression device uses the friction between the transmission roller 6 and the conveyor belt 8 as a power source to control the spraying of the spray structure 2. There is no need to set up an electrical control system, or invest in external control lines and external control boxes, which not only makes installation convenient, but also reduces investment costs.

[0025] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description.

The scope of protection of this utility model is not limited to the above-described embodiments. For those skilled in the art, several modifications and improvements can be made without departing from the concept of this utility model, and these all fall within the scope of protection of this utility model.
