A support assembly 8 is sleeved on the outer surface of the support screw rod 7;

[0026] In this embodiment, the support assembly 8 includes an adjustment assembly 81. A second motor 85 is installed at the left part of the upper end of the adjustment assembly 81. The output end of the second motor 85 is fixedly connected with a spray assembly 82. The right end of the spray assembly 82 is fixedly connected through a connecting pipe 83. The right end of the connecting pipe 83 is fixedly connected through a water pump 84, and the water pump 84 is fixedly connected with the fixed plate 1; The adjustment assembly 81 includes a support plate 811. Sliders 812 are fixedly connected to the rear parts of the left and right ends of the support plate 811. Two telescopic cylinders 813 are fixedly connected to the front end of the support plate 811. The output ends of the two telescopic cylinders 813 are jointly fixedly connected with a support plate 814. Two support blocks 815 are fixedly connected to the upper end of the support plate 814. Both of the two sliders 812 are inserted and connected with the fixed frame 5; The output end of the second motor 85 passes through the right support block 815 and is fixedly connected with a rotating block 825, and the rotating block 825 is movably connected with the left support block 815 through a connecting shaft; The water pump 84 is fixedly connected through a pipeline to penetrate the water tank 4.

[0027] Through the above solution: During the process of spraying and dust reduction on the mining face by the support assembly 8, the height adjustment process of the adjustment assembly 81 can be limited and supported by the two sliders 812. The two telescopic cylinders 813 jointly push the support plate 814, and the position of the spray assembly 82 arranged between the two support blocks 815 can be adjusted, improving flexibility. By setting the support assembly 8 to spray and dust reduce the mining face, the support plate 811 is sleeved on the support screw rod 7. The second motor 85 drives the spray assembly 82 to rotate, and the angle of the spray assembly 82 can be adjusted, improving flexibility. The water pump 84 is fixedly connected through a pipeline to penetrate the water tank 4 to convey water to the connecting pipe 83. The connecting pipe 83 is fixedly connected through to penetrate the annular pipe 824 on the spray assembly 82 to supply water to the annular pipe 824 and several nozzles 823.

[0028] In this embodiment, the spraying assembly 82 includes a support ring 821. A rotating block 825 is fixedly connected to the lower part of the outer surface of the support ring 821. A plurality of third motors 822 are fixedly connected to the inner ring wall of the support ring 821 in an annular array. The output ends of the plurality of third motors 822 are fixedly connected with spray nozzles 823. An annular pipe 824 is fixedly connected to the inner ring wall of the support ring 821. And the annular pipe 824 and the plurality of spray nozzles 823 are connected through rubber hoses in a penetrating manner. The rotating block 825 is inserted and connected with the two support blocks 815.

[0029] Through the above scheme: The spraying assembly 82 can be used to perform spray dust reduction treatment on the excavation face. The annular pipe 824 can supply water to the plurality of spray nozzles 823. The plurality of third motors 822 can respectively rotate and adjust the use angles of the plurality of spray nozzles 823, so as to adjust the spraying range size of the entire spraying assembly 82 and improve flexibility.

[0030] It should be noted that the present utility model is a spray dust reduction device for an excavation face. During use, the device fixedly connects the water pump 84 and the water tank 4 through a pipeline. When the water pump 84 is started, it will draw water from the water tank 4 and transport the water to the connecting pipe 83 through the pipeline. The connecting pipe 83 serves as a water transmission channel and further transports the water to the annular pipe 824 on the spraying assembly 82. This step ensures that water can be stably and continuously supplied to the spraying system. The annular pipe 824, as the main water supply pipeline of the spraying assembly 82, is connected to the connecting pipe 83 through a penetrating fixed connection. After the water enters the annular pipe 824, it will be distributed to the plurality of spray nozzles 823. The spray nozzles 823 are fixedly connected to the annular pipe 824 through rubber hoses in a penetrating manner to ensure that each spray nozzle 823 can obtain a stable water flow. When the water sprays out from the spray nozzles 823, it will form fine water mist, thereby achieving the effect of dust reduction. The four universal wheels 2 allow the entire spray dust reduction device to move freely on the excavation face to adapt to different working environments and requirements. By driving the support screw 7 to rotate through the first motor 6, the use height of the support assembly 8 (including the spraying assembly 82) can be adjusted. This adjustment improves the applicability and flexibility of the spray dust reduction device at different heights. The rotation of the second motor 85 can drive the entire spraying assembly 82 to rotate, thereby realizing the adjustment of the spraying angle. This adjustment enables the spray to cover a wider area of the excavation face. By respectively driving the plurality of spray nozzles 823 to rotate through the plurality of third motors 822, the spraying range size of the spraying assembly 82 can be further adjusted. This fine adjustment can ensure that the spray more evenly covers the excavation face and improves the dust reduction effect. The two telescopic cylinders 813 jointly push the pallet 814 to realize fine adjustment of the use position of the spraying assembly 82. This adjustment helps to ensure that the spray can accurately be sprayed onto the area where dust reduction is required.
