[0002] When a coal mining machine is used for mining, a large amount of dust will be generated, and a spray device is needed to reduce the dust.
[0003] For example, the Chinese patent publication number CN219262365U discloses a coal mining machine spray device, which includes a mounting plate, a spray mechanism, a mounting mechanism and a control mechanism; the spray mechanism includes a nozzle and a water tank, a water tank is mounted on one side of the top of the mounting plate, a water pump is mounted on the top of the water tank, one side of the top of the water pump is connected to the nozzle through a water pipe, a mounting frame is mounted on one side of the nozzle, the mounting frame is sleeved on the surface of the mounting block, and a positioning rod is mounted on the inner side of the mounting frame, a positioning groove is provided on one side of the mounting block, and one end of the positioning rod extends to the inside of the positioning groove. The present application is simple to operate, and is easy to install through the mounting plate and mounting bolts. Water can be transported to the nozzle through the water pipe through the water tank and the water pump, which is convenient for spraying and dust reduction. Moreover, the nozzle can be easily installed and replaced through the mounting frame, the plug rod and the mounting block to avoid clogging after long-term use.
[0004] Some problems were found during the use of the above-mentioned existing coal mining machine spray device. First, in order to ensure that the water pipe can always be connected to the nozzle during the movement of the nozzle, the water pipe needs to be a hose and has a long length. During the movement of the nozzle, the water pipe will be driven to move, and the water pipe is easy to bend and entangled together, resulting in obstruction of clean water delivery and the nozzle cannot work normally. Secondly, a screw is used to drive the nozzle to move up and down. In the coal mine, slag and dust will enter the screw thread groove, which may easily cause the sleeve to be stuck.

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] In this embodiment, the limiting slider 301 is slidably installed inside the first limiting groove 202, so that the nozzle 3 can be easily moved. The first limiting groove 202 is provided with a through state, so that dust, slag and other impurities entering the first limiting groove 202 can be easily removed, and the limiting slider 301 is prevented from being stuck inside the first limiting groove 202 due to the accumulation of impurities. When the nozzle 3 moves, the linear distance between the nozzle 3 and the water tank 101 changes, and the two fixed frames 4 are symmetrically staggered. At this time, the two tensioning wheels 503 approach each other to release a certain output hose 102, and the two tensioning wheels 503 move away from each other to retract a certain output hose 102, so that the output hose 102 is in a bent and tightened state, such as Figure 1 As shown, the output hoses 102 are prevented from being loosely stacked together, causing problems such as entanglement or bending during use.
[0025] Among them, in order to achieve the purpose of conveying clean water, the present device is implemented by the following technical scheme: a pump is fixedly installed inside the mounting plate 1, an output hose 102 is fixedly installed at the output end of the pump, a second hydraulic adjusting rod 203 is fixedly installed in the adjusting frame 201, one end of the second hydraulic adjusting rod 203 is fixedly connected to the limiting slider 301, a connector 302 is fixedly installed in the limiting slider 301, the connector 302 is communicated with the inside of the nozzle 3, and the other end of the output hose 102 is fixedly connected to the connector 302.
[0026] A certain amount of clean water can be stored in the water tank 101. When the pump is started, the clean water will be pumped into the output hose 102. The output hose 102 is fixedly connected to the connector 302, so that the clean water can be transported to the nozzle 3 through the connector 302 for spraying.
[0027] Among them, in order to achieve the purpose of keeping the output hose 102 in a taut state, the present device is implemented by the following technical scheme: a slide rod 402 is fixedly installed in the second limit groove 401, a return spring 403 is sleeved on the slide rod 402, a through hole 501 is opened in the earth-shaped sliding block 5, the through hole 501 is slidably matched with the slide rod 402, a U-shaped ring 504 is sleeved on the connecting shaft 502, a mounting seat 6 is fixedly installed on the mounting plate 1, and a guide wheel 601 is rotatably installed on the front of the mounting seat 6.
[0028] The sliding rod 402 and the through hole 501 are slidably matched, so that the soil-shaped slider 5 can only slide inside the second limit groove 401. The return spring 403 can provide a certain thrust for the soil-shaped slider 5. The soil-shaped slider 5 will move to both sides under the thrust, so that the tensioning wheels 503 are separated from each other, so that the output hose 102 is always in a taut state. The U-shaped ring 504 is sleeved on the connecting shaft 502 and cooperates with the tensioning wheel 503 to prevent the output hose 102 from slipping off the tensioning wheel 503. The guide wheel 601 is used to guide the direction of the output hose 102.
[0029] The working principle and use process of the utility model are as follows: when using the device, it is necessary to place the device in a suitable position, and starting the first hydraulic telescopic rod 2 can drive the adjustment frame 201 to move, thereby driving the nozzle 3 to move up and down, and starting the second hydraulic adjustment rod 203 can drive the limit slider 301 to move, and the limit slider 301 can drive the nozzle 3 to move left and right, thereby adjusting the position of the nozzle 3, and at the same time, the two tensioning wheels 503 will be adjusted according to the nozzle 3, approaching or moving away from each other, so that the output hose 102 is always in a taut state. After the adjustment is completed, start the pump to transport the clean water stored in the water tank 101 to the nozzle 3 for spraying operation.
