[0019] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0020] like Figure 1-4As shown, the utility model provides a technical solution: a dust suppression device for coal mine excavation, comprising a bottom plate 1, a plurality of moving wheels 101 are fixedly connected to the bottom end of the bottom plate 1, an inner box 2 is fixedly connected to the top end of the bottom plate 1, a rubber ring 201 is fixedly connected to the top end of the inner box 2, and an outer box 202 is fixedly connected to the top end of the rubber ring 201. Since the outer box 202 has a larger diameter than the inner box 2, and the material of the rubber ring 201 is bendable, the outer box 202 can be located at the top end of the bottom plate 1 and sleeved on the outer end of the inner box 2 after pressing the outer box 202 downward, and the rubber ring 201 is in a folded state between the inner wall of the outer box 202 and the outer wall of the inner box 2. At this time, the position of all devices on the top end of the top cover 5 is lowered along with the outer box 202, and the overall volume of the device is reduced. The outer box 202 can be folded and reduced in size, so that the device as a whole does not occupy a large storage space when not in use. The left and right side ends of the outer box 202 are fixedly connected with a supporting mechanism for supporting the outer box 202. The supporting mechanism can support the outer box 202 after the outer box 202 and the inner box 2 are unfolded to prevent the outer box 202 from collapsing downward. The top of the outer box 202 is installed with a top cover 5 by a buckle. The top of the top cover 5 is fixedly connected with two groups of vertical plates 501. A dust reduction mechanism is provided between the inner sides of the two groups of vertical plates 501. The dust reduction mechanism includes a spraying assembly. The spraying assembly is arranged between the inner sides of the two groups of vertical plates 501. A pumping assembly is provided between the top of the top cover 5 and the bottom of the spraying assembly. A blowing assembly is provided inside the spraying assembly. The dust reduction mechanism can realize dust reduction treatment in the coal mine excavation area.

[0021] As an implementation method in this embodiment, Figure 1 and Figure 2 As shown, the supporting mechanism includes a side plate 203, which is fixedly connected to the side end of the outer box 202, and a handle 206 is fixedly connected to the side end of the side plate 203. Through the arrangement of the handle 206 and the moving wheel 101, it is also convenient to move flexibly in the construction area of ​​coal mine excavation, and the range of the dust reduction area can be increased. A side groove 204 is opened at the side end of the side plate 203, and a supporting plate 4 is installed between the inside of the side groove 204 and the top of the bottom plate 1. The bottom end of the bottom plate 1 is fixedly connected to a placement frame 102, and the placement frame 102 can facilitate the removal of the support plate 4. For placement and storage, a socket 401 is provided at the side end of the support plate 4, and mounting grooves 205 are provided at intervals at the side ends of the side grooves 204. A fixing assembly for fixing the support plate 4 is provided inside the mounting grooves 205. During implementation, the support plate 4 is fixed in the side grooves 204 by the fixing assembly, which can facilitate the support of the outer box 202 to prevent the outer box 202 from collapsing downward, making the outer box 202 and the inner box 2 more stable after being unfolded. Then the top cover 5 can be opened to transport water to the inside of the outer box 202 and the inner box 2. After the top cover 5 is re-covered, subsequent dust suppression spraying can be facilitated.

[0022] Furthermore, the fixing assembly includes an insertion rod 3, which is inserted into the mounting groove 205 from the outer side end of the side plate 203, and the outer end of the insertion rod 3 is fixedly connected to a circular plate 301, and the outer end of the insertion rod 3 is sleeved with a spring 302, and the side end of the insertion rod 3 is fixedly connected to a pull rod 303, and the insertion rod 3 is adapted to the socket 401. In implementation, the insertion rod 3 is moved by pulling the pull rod 303, and the circular plate 301 will press the spring 302 to shrink, and the support plate 401 will be pressed. Placed in the side groove 204, the bottom end of the support plate 4 contacts with the top of the bottom plate 1, thereby supporting the outer box 202. At this time, after the support plate 4 is placed in the side groove 204, the side end socket 401 is opposite to the position of the insertion rod 3. At this time, after the pull rod 303 is released, the spring 302 will push the circular plate 301 to drive the insertion rod 3 to rebound, so that the insertion rod 3 is inserted into the socket 401, thereby limiting and fixing the support plate 4 to prevent the support plate 4 from leaving the side groove 204.

[0023] As an implementation method in this embodiment, Figure 3 and Figure 4 As shown, the spray assembly includes an outer cylinder 6, which is rotatably arranged between the side ends of two groups of vertical plates 501 through a rotating rod, and a motor 602 is fixedly installed on the side end of one group of vertical plates 501, and the output end of the motor 602 is connected to the rotating rod. An inner cylinder 601 is fixedly installed inside the outer cylinder 6, and a cavity 603 is formed between the inner wall of the outer cylinder 6 and the outer wall of the inner cylinder 601. A plurality of atomizing nozzles 604 are fixedly installed on the side end of the outer cylinder 6 near the cavity 603. During implementation, the rotating rod, the outer cylinder 6 and the inner cylinder 601 can be driven to rotate by starting the motor 602, thereby facilitating the expansion of the dust reduction spraying range.

[0024] Furthermore, the pumping assembly includes a pump 8, which is fixedly mounted on the top of the top cover 5. An input pipe 801 is installed at the input end of the pump 8, and the input pipe 801 extends to the bottom end of the inner box 2. An output pipe 802 is installed at the output end of the pump 8, and the output pipe 802 is fixedly connected to the outer cylinder 6. During implementation, by starting the pump 8, the water in the outer box 202 and the inner box 2 is pumped into the cavity 603 through the output pipe 802 through the input pipe 801. At this time, the water will be sprayed out through the atomizing nozzle 604. With the rotation of the outer cylinder 6 and the inner cylinder 601, the range of dust reduction spraying can be increased.

[0025] As an implementation method in this embodiment, Figure 3 and Figure 4As shown, the blowing assembly includes a fixing frame 7, which is fixedly connected to the inner wall of the inner cylinder 601, and a motor 2 701 is fixedly installed on the side end of the fixing frame 7, a rotating rod 702 is installed on the output end of the motor 2 701, and a fan blade 703 is fixedly installed on the side end of the rotating rod 702, and a filter screen 704 is threadedly connected at the port of the inner cylinder 601. During implementation, by starting the motor 2 701 to drive the rotating rod 702 and the fan blade 703 to rotate, the sprayed atomized water can be blown and diffused, and the dust reduction efficiency of the atomized water can be accelerated. The dust brought into the inner cylinder 601 when the fan blade 703 rotates can be filtered through the filter screen 704, and the filter screen 704 can be disassembled and cleaned by rotating it.

[0026] Working principle: When the dust suppression device is not in use, it is in a folded state. By pulling the pull rod 303 to drive the insertion rod 3 to move, the circular plate 301 will press the spring 302 to shrink, so that the insertion rod 3 leaves the insertion hole 401. At this time, the support plate 4 can be taken out from the side groove 204, so that the outer box 202 loses the support of the support plate 4, and then the support plate 4 is placed in the placement rack 102. At this time, since the outer box 202 has a larger diameter than the inner box 2, and the material of the rubber ring 201 is bendable, the outer box 202 can be pressed downward to make the outer box 202 It is located at the top of the bottom plate 1 and is sleeved on the outer end of the inner box 2, while the rubber ring 201 is folded between the inner wall of the outer box 202 and the outer wall of the inner box 2. At this time, the positions of all devices on the top of the top cover 5 are lowered along with the outer box 202, so that the overall volume of the device is folded and reduced, so that the device as a whole does not occupy a large storage space when not in use. At the same time, since the volume of the device is not very large after being unfolded, the handle 206 and the moving wheel 101 can be set to facilitate flexible movement in the construction area of ​​coal mine excavation, which can increase the range of the dust reduction area.

[0027] The above embodiments are only used to illustrate the technical solution of the present invention, but not to limit it.
