[0030] The brush cleaning assembly includes a lifting cylinder 206 arranged on the side wall of the movable frame 201, and a lifting plate 207 is provided at the lower end of the lifting cylinder 206. A rotating plate 209 is rotatably installed at the lower end of the lifting plate 207, and a rotating motor 208 is installed at the rotating end of the rotating plate 209. A cleaning brush 211 is rotatably installed at one end of the rotating plate 209 close to the fabric tube 205. The bristles on the cleaning brush 211 are tilted downward at one end away from the center of the cleaning brush 211, and a rotating motor 210 is installed at the rotating end of the cleaning brush 211. A vibration assembly for driving the fabric tube 205 to vibrate is provided on the side of the cleaning brush 211 close to the lifting plate 207.

[0031] The vibration assembly includes a convex strip 214 arranged on one side of the pipe sleeve 204 near the lifting plate 207, and a connecting plate 212 is provided below the convex strip 214. The connecting plate 212 is fixedly connected to the rotating plate 209. A convex block 213 is slidably installed on the upper end of the connecting plate 212. A compression spring is connected between the convex block 213 and the connecting plate 212. The convex block 213 slides in cooperation with the convex strip 214. Concrete spreading equipment is needed in water conservancy and hydropower construction. The concrete is spread in different positions through the adjustment mechanism and the spreading assembly. After the concrete is spread, the cleaning assembly is used to clean the concrete remaining on the inner wall of the distribution pipe 205 outlet in all directions. The cleaning assembly generates a certain vibration on the distribution pipe 205 while moving up and down to clean the inner wall of the distribution pipe 205, thereby effectively causing the cleaned concrete to vibrate downward, thereby improving the cleaning quality and making the cleaning more comprehensive without affecting the normal use of the distribution pipe 205 in the later stage.

[0032] Working principle: First, start the adjustment motor 303 to drive the fixed sleeve 301 to rotate, use the lifting cylinder 302 to drive the rotating frame 304 to move up and down, and then use the telescopic cylinder 306 to push the connecting seat 307 to move back and forth, thereby adjusting the cloth position of the cloth pipe 205 in all directions to increase the coverage area of ​​the cloth.

[0033] Then connect the input end of the delivery pipe 216 to the external concrete delivery box, and then pump the mixed concrete into the distribution pipe 205 through the pump body 215, and then drive the moving cylinder 203 to push the distribution pipe 205 to move back and forth to distribute the concrete in all directions in the distribution area, so that the concrete is spread more evenly.

[0034] After the concrete is distributed, some residual concrete may adhere to the inner wall of the distribution pipe 205 outlet, thereby driving the moving cylinder 203 to drive the distribution pipe 205 to move the distribution pipe 205 to the middle position of the moving frame 201. In the initial state, the cleaning brush 211 is located on the side of the lifting plate 207 away from the distribution pipe 205. Then the lifting cylinder 206 is driven to drive the lifting plate 207 to move downward, driving the cleaning brush 211 to move downward, and then driving the rotating motor 208 to drive the rotating plate 209 to rotate, thereby driving the cleaning brush 211 to rotate to the bottom of the distribution pipe 205. Then the rotating motor 210 is driven to drive the cleaning brush 211 to rotate at high speed, and then the lifting cylinder 206 is used to drive the cleaning brush 211 to move up and down, thereby cleaning the residual concrete on the inner wall of the distribution pipe 205.

[0035] When the rotating plate 209 moves upward, it drives the connecting plate 212 upward, and the protrusion 213 at the upper end of the connecting plate 212 squeezes and collides with the ridge 214 on the side wall of the pipe sleeve 204, prompting the ridge 214 to drive the pipe sleeve 204 to vibrate, thereby driving the distribution pipe 205 to vibrate, which is more conducive to the falling of the concrete after cleaning, completing the cleaning operation of the inner wall of the distribution pipe 205, thereby improving the cleaning quality, cleaning more comprehensively, and not affecting the normal use of the distribution pipe 205 in the later stage. After cleaning the inner wall of the distribution pipe 205, the cleaning brush 211 moves to the side of the lifting plate 207 away from the distribution pipe 205, so that the cleaning brush 211 does not affect the normal distribution operation of the distribution pipe 205.

[0036] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions are merely illustrative of the principles of the present invention. Various changes and improvements may be made to the present invention without departing from the spirit and scope of the present invention, and such changes and improvements shall fall within the scope of the present invention as claimed.
