An electromagnetic valve water inlet pipe 16 is fixedly installed on the left side of the water tank 9. The water outlet end of the water pump 11 is fixedly installed with a conduit 17 extending into the inside of the spray box 10, and a nozzle 18 is fixedly installed on the conduit 17. The water pump 11 transports the water inside the water tank 9 to the conduit 17, and then sprays it out from the nozzle 18 to spray and reduce the dust inside the spray box 10.

[0040] In the case implementation, a controller 14 is fixedly installed on the front side of the crushing box 2. The controller 14 is electrically connected to the electronic components in this patent through wires, so as to facilitate the operation of the controller 14 to control the operation of the electronic components. A maintenance door 15 is arranged on the front side of the crushing box 2. The maintenance door 15 can facilitate the maintenance of the component mechanism inside the crushing box 2 and the replacement of the raw material sieve mesh 5.

[0041] In the case implementation, the crusher 3 includes a driving motor and a crushing shaft. Crushing plates 20 are fixedly installed on the inner walls on the left and right sides of the crushing box 2. Through the cooperation among the driving motor, the crushing shaft and the crushing plates 20, the steel casting raw materials can be effectively and quickly crushed.

[0042] A using method of a crushing device for steel casting raw material processing, including the above-mentioned crushing device for steel casting raw material processing, and the operation steps are as follows:

[0043] Step 1: First, pour the steel casting raw materials into the inside of the crushing box 2 from the feed hopper 13, and then quickly crush them through the crusher 3 and the crushing plates 20;

[0044] Step 2: Then, the servo motor 701 runs to drive the output shaft to drive the rotating shaft 702 to rotate. The rotation of the rotating shaft 702 drives the rotating block 703 to rotate, so that the rotating block 703 rotates to push the raw material sieve mesh 5;

[0045] Step 3: The up and down movement of the raw material sieve mesh 5 drives the installation strip 405 to move. The movement of the installation strip 405 drives the moving block 403 to move, so that the moving block 403 moves on the outside of the fixed rod 402. The movement of the moving block 403 presses against the spring 404, and the elasticity of the spring 404 is used to vibrate and accelerate the raw material sieve mesh 5 for screening;

[0046] Step 4: Meanwhile, a large amount of dust is generated when the steel casting raw materials are broken. The dust inside the crushing box 2 is sucked into the inside of the spray box 10 by the dust collector 12, and the water pump 11 transports the water inside the water tank 9 to the conduit 17 and then sprays it out through the nozzle 18 to spray and reduce the dust inside the spray box 10;

[0047] Step 5: The selected steel casting raw materials can be exported from the inside of the crushing box 2 through the guide plate 8.

[0048] In summary, for the crushing device for steel casting raw material processing and its usage method, by setting the insertion rods 608, when it is necessary to disassemble the raw material screen 5 for replacement, first rotate the rotating rod 601 to make it rotate through the bearing 602. The rotation of the rotating rod 601 drives the gear 603 to rotate, so that the rotation of the gear 603 drives the engaged rack 606 to move. The rack 606 moves stably through the slider 607 and the guide rod 605, so that the two insertion rods 608 move out of the slots inside the installation strip 405. At this time, the installation strip 405 and the raw material screen 5 are no longer fixed. Then pull the raw material screen 5 to move it away from the installation strip 405, so as to facilitate the disassembly of the raw material screen 5 for replacement. The same operation can be carried out when installing the raw material screen 5.

[0049] Moreover, by setting the servo motor 701 and the spring 404, when the crusher 3 crushes the steel casting raw materials, first operate the servo motor 701 to drive the output shaft to drive the rotating shaft 702 to rotate. The rotation of the rotating shaft 702 drives the rotating block 703 to rotate, so that the rotating block 703 pushes the raw material screen 5 upward. The up and down movement of the raw material screen 5 drives the installation strip 405 to move. The movement of the installation strip 405 drives the moving block 403 to move, so that the moving block 403 moves outside the fixed rod 402. The movement of the moving block 403 presses against the spring 404, and the elasticity of the spring 404 is used to make the raw material screen 5 vibrate and accelerate. Thus, the function of quickly screening out the steel casting raw materials is realized.
