After the motor is installed on the fixing frame 1, the motor can drive the transmission shaft to rotate through the belt, and then drive the striking plate 17 to rotate to generate striking force on the material entering the casing 201 to perform the first step of crushing. After the material is crushed by the first step, it is hit by the striking plate 17 onto the counter-attack plate 26 to collide and be crushed again, and the process is repeated. The material is beaten into sand particles through reciprocating impact and counterattack, and finally falls from the discharge hopper 4 onto the conveyor belt of the conveying device 27, and is finally transported to the designated position through the conveying device 27; in this process, the baffle plate arranged inside the fixed frame 1 can prevent the sand particles falling from the discharge hopper 4 from falling into the water tank 29, and the water flowing out of the discharge hopper 4 can flow through the gap between the baffle plate and the conveyor belt of the conveying device 27 and fall into the water tank 29, so that the water entering the inside of the casing 201 can be recycled.

[0029] The working principle of the impact crusher for sand making in the utility model is:

[0030] When in use, the external motor driving the transmission roller 5 rotates, and the transmission roller 5 rotates through the belt, which in turn drives the striking plate 17 to rotate to generate a striking force on the material entering the casing 201 to perform the first step of crushing. After the material is crushed by the first step, it is hit by the striking plate 17 onto the impact plate 26 to cause collision and crushing again, and the material is repeatedly struck and impacted back and forth, and finally is beaten into sand particles, and finally falls from the discharge hopper 4 onto the conveyor belt of the conveying device 27, and is finally transported to the designated position after being transported by the conveying device 27. , the synchronous water pump 30 and the conveying device 27 are started. The water pump 30 can be started to extract and pressurize the water inside the water tank 29, and finally sprayed out from the first nozzle 9 and the second nozzle 11 respectively. When water is sprayed out from the first nozzle 9, the striking plate 17, the mounting cylinder 13, the circular fixing plate 14 and the abutting plate 16 will be cooled down, thereby enhancing durability. When water is sprayed out from the second nozzle 11, the material entering the casing 201 will be soaked, thereby preventing the material from generating dust during the collision process. Furthermore, the impact plate 26 can be cooled down, thereby enhancing durability of the impact plate 26.

[0031] It is worth noting that: in the utility model, the motor driving the transmission roller 5, the operating motor in the transmission device and the water pump 30 are all electrically connected to the external power supply through the electric control cabinet, and the action is controlled by the electric control cabinet, which is a common setting in the field, so no further explanation is given in the utility model.

[0032] This article uses specific examples to illustrate the principles and implementation methods of the utility model. The above examples are only used to help understand the method and core ideas of the utility model. It should be pointed out that for ordinary technicians in this technical field, without departing from the principles of the utility model, the utility model can also be improved and modified, and these improvements and modifications also fall within the scope of protection of the claims of the utility model.
