Specific embodiments

[0025] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0026] The present utility model provides a Figures 1-4 dust-proof concrete mixing station as shown, including a mixer 1 and a main body 2 of a fog cannon. The main body 2 of the fog cannon is composed of a main body 201 of the fog cannon and a water tank 202. A self-closing mechanism 3 is provided on one side of the main body 201 of the fog cannon. The self-closing mechanism 3 is used to automatically close the switch of the fog cannon to avoid the situation of the fog cannon idling.

[0027] The self-closing mechanism 3 includes a straight pipe 301, and the straight pipe 301 is fixedly connected to the bottom of the inner wall of the water tank 202. The straight pipe 301 is communicated with the feeding hole of the water tank 202. A lifting cross plate 302 is sleeved on the outer wall of the straight pipe 301. A plurality of floating plates 303 are arranged at the bottom of the lifting cross plate 302. The number and size of the floating plates 303 can be changed according to actual situations. The straight pipe 301 passes through the gap between two of the floating plates 303. The plurality of floating plates 303 are fixedly connected to the bottom of the lifting cross plate 302 at equal intervals. A U-shaped binding rod 313 is arranged at the top of the lifting cross plate 302. The U-shaped binding rod 313 is fixedly connected to the top of the lifting cross plate 302. The connection work between the connection rope 304 and the lifting cross plate 302 is completed by tying the connection rope 304 to the U-shaped binding rod 313. A rope passing hole is opened at the top of the water tank 202. The connection rope 304 is arranged in the inner cavity of the rope passing hole. The inside of the connection rope 304 can be mixed with metal wires to increase the strength of the connection rope 304. Two guiding components 305 are arranged outside the connection rope 304. The guiding components 305 play a guiding role for the connection rope 304. One end of the connection rope 304 is provided with a strip-shaped block 306. The strip-shaped block 306 is fixedly connected to one side of the water tank 202. A T-shaped hole is opened on the back of the strip-shaped block 306. A flashlight 307 is arranged in the inner cavity of the T-shaped hole. The flashlight 307 can be replaced by other lighting devices. The premise is that the light source can irradiate the photosensitive switch 308 through the light passing hole 311. A T-shaped hole plug 312 is arranged on the back of the flashlight 307. The T-shaped hole plug 312 plays a role in closing the T-shaped hole. The outer wall of the T-shaped hole plug 312 is threadedly connected to the inner wall of the T-shaped hole. A light transmitting hole is opened on one side of the inner wall of the T-shaped hole. A rectangular cavity is opened in the strip-shaped block 306. A photosensitive switch 308 is installed on one side of the inner wall of the rectangular cavity. When no light source irradiates the photosensitive switch 308, the photosensitive switch 308 will control the fog cannon machine to close. Strip-shaped holes are symmetrically opened at the top and bottom of the strip-shaped block 306. The lifting vertical plate 309 is arranged in the inner cavities of the two strip-shaped holes. A light passing hole 311 is opened on the front of the lifting vertical plate 309. An anti-slip and anti-disengagement hole is opened on one side of the lifting vertical plate 309. An anti-slip and anti-disengagement rod 314 is slidably sleeved in the inner cavity of the anti-slip and anti-disengagement hole. The anti-slip and anti-disengagement rod 314 and the anti-slip and anti-disengagement hole are used to ensure that the lifting vertical plate 309 will not completely disengage from the strip-shaped block 306. The anti-slip and anti-disengagement rod 314 is fixedly connected to the inner cavity of the rectangular cavity. A connection cross plate 310 is arranged at the top of the lifting vertical plate 309. The connection cross plate 310 is used for the connection work between the connection rope 304 and the lifting vertical plate 309. The bottom of the connection cross plate 310 is fixedly connected to the top of the lifting vertical plate 309. The top of the connection cross plate 310 is fixedly connected to one end of the connection rope 304;

[0028] The guiding component 305 is composed of a U-shaped plate 3051 and an I-shaped wheel 3052. The I-shaped wheel 3052 is rotatably connected to the inner cavity of the U-shaped plate 3051. The connecting rope 304 is movably arranged between the I-shaped wheel 3052 and the U-shaped plate 3051. One of the U-shaped plates 3051 is fixedly connected to the top of the water tank 202. The bottom of the other U-shaped plate 3051 is fixedly connected with two extension plates 4. The extension plates 4 are used for installing the U-shaped plate 3051 and also for increasing the distance between the vertical part of the connecting rope 304 and the water tank 202. Both of the two extension plates 4 are fixedly connected to one side of the water tank 202.

[0029] The working principle of the present utility model:

[0030] As the water resources in the water tank 202 of the fog cannon machine for the concrete mixing plant gradually decrease, the lifting cross plate 302 will move along with the liquid level through a plurality of floating plates 303. During this process, the lifting cross plate 302 will drive the connecting rope 304 to move. When the connecting rope 304 is in a taut state, as the lifting cross plate 302 continues to move downward, the lifting cross plate 302 will drive the connecting cross plate 310 and the lifting vertical plate 309 to move vertically upward through the connecting rope 304. When the light source emitted by the flashlight 307 cannot pass through the light passing hole 311 on the lifting vertical plate 309 and irradiate on the photosensitive switch 308, the photosensitive switch 308 will control the fog cannon machine to shut down, avoiding the situation of the fog cannon machine idling, preventing the components of the fog cannon machine from being damaged, and improving the service life of the fog cannon machine.

[0031] Finally, it should be noted that the above are only the preferred embodiments of the present utility model and are not used to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included in the protection scope of the present utility model.
