Description

Technical Field

[0001] This utility model belongs to the field of coal mine dust suppression technology, specifically relating to a full-section spray device. Background Technology

[0002] Dust control is one of the key challenges in coal mine production, as the concentration of dust in the air directly affects the health and safety of underground workers. Therefore, full-face dust suppression spraying must be installed within 50 meters of the underground tunneling face. However, with the continuous extension of mining distances and the increasing complexity of mining layouts, conventional water curtains cannot be used for dust suppression in many locations, and these conventional water curtains are also too long. Existing full-face spraying devices need to be suspended from the roof, requiring construction personnel to climb to install them, which is extremely inconvenient. Furthermore, their spraying effect is unsatisfactory, their structure is complex, and their size is too large to be moved in conjunction with bridge-type transfer machines or self-propelled conveyor tail sections. Utility Model Content

[0003] In view of this, the purpose of this utility model is to provide a full-section spraying device that solves the problems of the existing full-section spraying devices being unable to be portable, having a complex structure, and being too large.

[0004] To achieve the above objectives, the technical solution of this utility model is implemented as follows:

[0005] A full-section spraying device for coal mining equipment includes a water inlet mechanism, a nozzle mechanism, and a support mechanism. The water inlet mechanism is located on one side of the nozzle mechanism. One end of the support mechanism is connected to the coal mining equipment, and the other end is connected to the nozzle mechanism. In use, the water inlet mechanism transports water to the nozzle mechanism, and the nozzle mechanism sprays the water out.

[0006] In the above scheme, the support mechanism includes a support rod and a connector. One end of the support rod is connected to the nozzle mechanism, and the other end is connected to the coal mining equipment through the connector.

[0007] In the above scheme, the full-section spraying device also includes a wind pressure mechanism, which is connected to the nozzle mechanism.

[0008] In the above scheme, the air pressure mechanism is an arc-shaped pipeline.

[0009] In the above scheme, the nozzle mechanism includes a water tank and several nozzle assemblies, with the several nozzle assemblies disposed on the side end of the water tank; the water inlet mechanism, the air pressure mechanism, and the support rod are all connected to the water tank.

[0010] In the above scheme, the cross-section of the water bag is circular.

[0011] In the above scheme, the nozzle assembly includes a nozzle tube and a nozzle, and the nozzle is connected to the water bag through the nozzle tube.

[0012] In the above scheme, the nozzle is provided with spray holes for spraying.

[0013] In the above scheme, the water inlet mechanism is an arc-shaped pipe.

[0014] Compared with the prior art, this utility model enhances the dust removal effect by setting a nozzle mechanism on the support mechanism, which enables the support mechanism to support the nozzle mechanism to a certain height. This utility model also uses the support mechanism to connect the nozzle mechanism and the coal mining equipment, so that the nozzle mechanism can move with the coal mining equipment, enhancing portability. This utility model has a simple structure and low cost, and is worth promoting and using. Attached Figure Description

[0021] Example 1

[0022] Embodiment 1 of this utility model provides a full-section spraying device for use in coal mine equipment. See [link / reference]. Figures 1 to 3 It includes a water inlet mechanism 1, a nozzle mechanism 2, and a support mechanism 3. The water inlet mechanism 1 is located on one side of the nozzle mechanism 2. One end of the support mechanism 3 is connected to the coal mining equipment, and the other end is connected to the nozzle mechanism 2. When in use, the water inlet mechanism 1 transports the water to the nozzle mechanism 2, and the nozzle mechanism 2 sprays the water out.

[0023] By adopting the above solution, this utility model enhances the dust removal effect by setting the nozzle mechanism 2 on the support mechanism 3, so that the support mechanism 3 can support the nozzle mechanism 2 to a certain height; this utility model also uses the support mechanism 3 to connect the nozzle mechanism 2 and the coal mining equipment, so that the nozzle mechanism can move with the coal mining equipment, enhancing portability; this utility model has a simple structure and low cost, and is worth promoting and using.

[0024] See Figure 1 and Figure 2 In a specific implementation of Embodiment 1 of this utility model, the support mechanism 3 further includes a support rod 31 and a connector 32. One end of the support rod 31 is connected to the nozzle mechanism 2, and the other end is connected to the coal mining equipment via the connector 32. The support rod 31 can support the nozzle mechanism 2 at a certain height, thus enabling dust removal over a larger area. The connector 32 can connect the support rod 31 to the coal mining equipment, allowing the full-section spraying device to move with the coal mining equipment, reducing the workload of construction personnel.

[0025] Furthermore, the coal mine equipment in this utility model can be a bridge transfer machine or a self-propelled tail section machine, etc. In Embodiment 1 of this utility model, the coal mine equipment preferably adopts a bridge transfer machine.

[0026] Furthermore, in Embodiment 1 of this utility model, the connector 32 is connected to the bridge transfer machine by bolts.

[0027] See Figure 1 In a specific implementation of Embodiment 1 of this utility model, the full-section spraying device further includes a wind pressure mechanism 4, which is connected to the nozzle mechanism 2. When the pressure of the full-section spraying device is insufficient, the wind pressure mechanism 4 is used to pressurize the water in the nozzle mechanism 2, thereby increasing the spray pressure.

[0028] In a specific implementation of Embodiment 1 of this utility model, the air pressure mechanism 4 is further configured as an arc-shaped pipeline. This arrangement facilitates connection to an external air pressure device without affecting the normal operation of the full-section spray device.

[0029] See Figures 1 to 3 In a specific implementation of Embodiment 1 of this utility model, the nozzle mechanism 2 further includes a water tank 21 and several nozzle assemblies 22, with the nozzle assemblies 22 disposed on the side of the water tank 21; the water inlet mechanism 1, the air pressure mechanism 4, and the support rod 31 are all connected to the water tank 21. The water tank 21 is used to store the liquid transported in by the water inlet mechanism 1, and the nozzle assemblies 22 are used to atomize and spray the liquid in the water tank 21.

[0030] In a specific implementation of Embodiment 1 of this utility model, the water bag 21 has a circular cross-section. This design expands the spray area and allows the spray to become a full-section spray.

[0031] See Figure 3 In a specific implementation of Embodiment 1 of this utility model, the nozzle assembly 22 further includes a nozzle tube 221 and a nozzle 222, with the nozzle 222 connected to the water tank 21 via the nozzle tube 221. The nozzle tube 221 is used to supply water flow; the nozzle 222 is used to spray water out.

[0032] Furthermore, the nozzle 222 is provided with spray holes for spraying.

[0033] See Figure 1 and Figure 2 In a specific implementation of Embodiment 1 of this utility model, the water inlet mechanism 1 is further designed as an arc-shaped pipe. This design facilitates connection to an external water supply pipe without affecting the normal operation of the full-section spray device.

[0034] The working principle of the full-section spraying device provided in Embodiment 1 of this utility model is as follows:

[0035] See Figures 1 to 3First, the support rod 31 is fixedly connected to the bridge transfer machine through the connector 32, at which time the support rod 31 supports the nozzle mechanism 2; then, the external water source enters the water tank 21 through the water inlet mechanism 1; finally, the water is sprayed out through the nozzle 222 to form a full-section spray; when the atomization effect is poor or the water pressure is insufficient, an external air pressure device is connected to pressurize the water in the water tank 21 to make the atomization effect of the full-section spray better.

[0036] In summary, this utility model enhances the dust removal effect by setting the nozzle mechanism 2 on the support mechanism 3, enabling the support mechanism 3 to support the nozzle mechanism 2 to a certain height. This utility model also utilizes the support mechanism 3 to connect the nozzle mechanism 2 to the coal mining equipment, allowing the nozzle mechanism to move with the coal mining equipment and enhancing portability. This utility model has a simple structure and low cost, and is worthy of widespread promotion and use.

[0037] The above description is merely a preferred embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
