[0034] In use, when the concrete mixing operation starts, the operator transports the sand and stone raw materials into the mixing barrel 44 through the feeding frame 3. At this time, the servo reducer motor 41 is started, the rotating shaft 42 rotates, the rotating shaft 42 rotates, the cross-shaped frame 43 also rotates, the mixing barrel 44 is driven by the cross-shaped frame 43 to start rotating, and the side roller 45 also rotates synchronously with the rotation of the mixing barrel 44. Under the joint action of the mixing barrel 44 and the side roller 45, the sand and stone raw materials start to tumble and rotate in the barrel, achieving sufficient mixing. During the mixing process, due to the different particle sizes, the raw materials with larger particle sizes will fall into the discharge frame 47 below through the discharge port 46 of the mixing barrel 44 under the action of centrifugal force and gravity. The discharge frame 47 transports these raw materials with larger particle sizes to the subsequent equipment, which is the existing equipment, so it is not described here. The raw materials with smaller particle sizes will fall onto the fixed inclined frame 48 between the adjacent side rollers 45 under the action of gravity. Further, at the same time when the mixing process is started, the dust suction pump 49 is opened, and the dust suction pump 49 starts to work to generate suction force. The suction force is transmitted to the horizontal pipe 411 through the vertical pipe 410, and then dispersed to the conical cover 413 through the horizontal pipe 411. The fixed frame 412 supports the horizontal pipe 411 and the conical cover 413. Under the action of the suction force, an air current is formed inside the conical cover 413. Since dust is generated during the mixing process, the dust is sucked into the conical cover 413 along with the air current. In order to prevent large impurities from being sucked in, a filter plate 414 is clamped at the bottom end of the conical cover 413. The mesh design of the filter plate 414 can effectively filter out larger impurities and only allow dust and small particles to pass through. The dust filtered by the filter plate 414 is sucked into the dust collecting cylinder 416 through the dust discharge pipe 415 along with the air current. The dust collecting cylinder 416 plays a role in collecting dust. When the dust in the dust collecting cylinder 416 accumulates to a certain extent, the dust collecting cylinder 416 can be removed to open the cylinder cover 417 for cleaning. Finally, the filter screen clamped at the bottom end of the filter 418 filters the gas. The filtered gas is discharged through the gas outlet provided on the filter 418 to ensure that the discharged gas meets the environmental protection requirements and reduces the pollution to the environment.

[0035] In an embodiment of the utility model, the stirring barrel 44 is externally provided with an auxiliary assembly 5, the auxiliary assembly 5 includes a hydraulic cylinder 51, the hydraulic cylinder 51 fixed end is hingedly installed on the outer wall of the frame 2, the hydraulic cylinder 51 piston end is hingedly installed with one end of the movable inclined frame 52, the other end of the movable inclined frame 52 is hingedly connected with the fixed inclined frame 48 through the hinge 53, in addition, the movable inclined frame 52 is provided with a through rectangular groove 54, the rectangular groove 54 is provided with multiple groups, the spacing between the two groups of side rollers 45 is greater than the width of the cross section of the rectangular groove 54, the collecting box 55 is placed on the top of the bottom plate 1, and the collecting box 55 is located directly below the rectangular groove 54, so that the sandstone raw materials are further screened better, in addition, the upper surface of one end of the fixed inclined frame 48 close to the movable inclined frame 52 is fixedly installed with a U-shaped plate 56, the outer wall of the frame 2 is fixedly installed with an N-shaped frame 57, and the N-shaped frame 57 is located directly above the hydraulic cylinder 51 fixed end, which can prevent the raw materials from splashing to the fixed end of the hydraulic cylinder 51.

[0036] In the use of the embodiment, when the sandstone raw materials preliminarily screened fall from the fixed inclined frame 48 to the movable inclined frame 52, the hydraulic cylinder 51 is started, the piston end starts to do reciprocating extension and retraction small amplitude movement, the movable inclined frame 52 is driven to reciprocate up and down small amplitude through the hinge 53, and the sandstone raw materials preliminarily screened falling from the fixed inclined frame 48 to the movable inclined frame 52 are further screened in the process of the movable inclined frame 52 swinging. The raw materials with smaller granularity fall into the collecting box 55 placed on the top of the bottom plate 1 below through the rectangular groove 54 under the action of gravity and the swinging of the movable inclined frame 52, and the raw materials with larger granularity cannot pass through the rectangular groove 54 due to the size being greater than the width of the cross section of the rectangular groove 54, are output from the movable inclined frame 52 and enter the subsequent collecting equipment, and the subsequent collecting equipment is the existing equipment, so the details are not described here. The U-shaped plate 56 can prevent the raw materials from entering the connection between the fixed inclined frame 48 and the movable inclined frame 52, avoid the raw materials from being stuck and affect the normal operation of the equipment, and simultaneously, the N-shaped frame 57 can effectively prevent the raw materials from splashing to the fixed end of the hydraulic cylinder 51 and protect the hydraulic cylinder 51.

[0037] In the application file, all the electrical components are electrically connected with the controller and 220V mains, and the controller is a conventional known device capable of controlling the servo reducer motor 41, the dust suction pump 49 and the hydraulic cylinder 51.
