DETAILED DESCRIPTION

[0023] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0024] This utility model provides a technical solution: such as Figure 1 and Figure 3 As shown in this embodiment, a spray structure for a horizontal mixer includes a gantry frame 1. A movable component 3 is installed inside the gantry frame 1. The movable component 3 includes two lead screws 303 rotatably connected inside the gantry frame 1 via bearings. Both lead screws 303 are vertically arranged. The two lead screws 303 are threaded onto the same mounting plate 302. Four vertically arranged guide rollers 301 are arranged inside the gantry frame 1. The mounting plate 302 is slidably sleeved on the outside of the four guide rollers 301. A bevel gear 304 is coaxially fixed at one end of the top of each of the two lead screws 303.

[0025] Inside the gantry frame 1, a horizontally arranged drive rod 305 is rotatably connected via bearings. Two bevel gears 2 are arranged outside the drive rod 305, and the two bevel gears 2 mesh with two bevel gears 1 304 respectively. A motor 1 306 is fixedly installed on the top of the outer wall of one side of the gantry frame 1. The output end of the motor 1 306 is coaxially fixed with one end of the drive rod 305.

[0026] When the motor 306 on the outside of the gantry frame 1 is started, the drive rod 305 connected to its output end is driven to rotate. The bevel gear 2 on its outside will rotate synchronously. The bevel gear 2 drives the two bevel gears 304 to rotate through meshing. Then the two lead screws 303 follow the rotation of the bevel gears 304. The mounting plate 302, which can only move horizontally due to the guide roller 301, will be driven by the lead screws 303 to move vertically. Consequently, the spray pipe 401 at its bottom will also move synchronously until the spray pipe 401 is just close to the mixer and then stops. This ensures that the water mist sprayed from the spray pipe 401 can just cover the opening of the mixer, ensuring that the dust can be just right to be suppressed, while the water mist will not fall outside the mixer.

[0027] like Figure 2 As shown, a spray assembly 4 is installed on the outside of the mounting plate 302. The spray assembly 4 includes a spray pipe 401 hinged to the bottom of the mounting plate 302 and the spray pipe 401 is horizontally arranged. An adapter component 5 is installed at both ends of the spray pipe 401. A horizontally arranged electric telescopic rod 402 is fixedly installed on the top outer wall of the mounting plate 302. A vertically arranged drive ring 403 is fixedly connected to the output end of the electric telescopic rod 402 and is sleeved on the outside of the spray pipe 401.

[0028] The electric telescopic rod 402 at the top of the installation plate 302 is started, the electric telescopic rod 402 drives the driving ring 403 to reciprocate forward and backward, the driving ring 403 can drive the spray pipe 401 to overturn at the bottom of the installation plate 302, when the spray pipe 401 overturns, the height is also increased, because the groove of the driving ring 403 is long strip-shaped, so that the upward movement of the spray pipe 401 is not hindered, so that the effect of increasing the spraying range is realized.

[0029] As shown in Figure 2 and Figure 4 , the adapter assembly 5 includes a support plate 501 fixedly connected to the circumferential outer wall of the spray pipe 401, two horizontally arranged limit rods 503 are fixedly connected inside the support plate 501, the same push rod 504 is slidably sleeved outside the limit rod 503, the push rod 504 is fixedly connected with a piston 505, and the piston 505 is slidably inserted into the inside of the spray pipe 401.

[0030] The support plate 501 is rotatably connected with a horizontally arranged screw rod two 502 through a bearing, the push rod 504 is threadedly sleeved outside the screw rod two 502, a motor two 506 is fixedly installed on the outer wall of one side of the support plate 501, and the output end of the motor two 506 is coaxially fixed with one end of the screw rod two 502.

[0031] If the stirring chamber is short, the motor two 506 outside the support plate 501 is started, the screw rod two 502 connected with the output end of the motor two 506 is driven to rotate, the push rod 504 limited to be able to only translate by the limit rod 503 is driven to move by the screw rod two 502, and then the piston 505 also slides in the inside of the spray pipe 401. At this time, water cannot continue to flow beyond the piston 505, and several nozzles on one side of the piston 505 cannot spray water, so that the number of water-spraying nozzles is adjusted, and the adaptability of the device is further enhanced.

[0032] As shown in Figure 1 , a plurality of rollers 2 are arranged on the outer wall of the bottom of the gantry 1, so that the movement of the device is facilitated.

[0033] As shown in Figure 3 and Figure 4 , the thread angles of the threads outside the two screw rods one 303 and the screw rod two 502 are smaller than the equivalent friction angles, so that both have self-locking property, and the positions of the installation plate 302 and the push rod 504 connected with the two are ensured not to be changed at will.
