[0022] In a preferred embodiment: a grinding motor is fixedly mounted on the outer wall of the box body 1, and a driving wheel is fixedly sleeved on the output shaft of the grinding motor, a transmission belt is rollingly connected to the middle of the driving wheel, a transmission gear is rollingly connected to the end of the transmission belt, and a driven gear is meshed on the outer wall of the transmission gear, and a grinding rod is fixedly mounted on the outer walls of the driven gear and the driving wheel.

[0023] In the above structure, through the set driven gear, driving wheel and transmission belt structure, the user can directly put the production raw materials into the box 1, and use the grinding motor to synchronously drive the two grinding rods to rotate, so that the raw materials are ground, and the use of a single grinding motor improves the energy utilization rate of the device.

[0024] In a preferred embodiment, the outer wall of the cam 3 is tightly fitted with the outer wall of the screen 4 , and the outer wall of the screen 4 is also slidably connected with the inner wall of the docking groove 11 .

[0025] In the above structure, by means of the cam 3, the screen 4 and the docking groove 11 structure, when the cam 3 rotates, it will come into contact with the screen 4, causing the outer wall of the screen 4 to slide along the inner wall of the strip groove 6 and the docking groove 11 at the same time, so that the screen 4 can screen the raw materials after grinding when it contacts the raw materials, thereby improving the production quality of the device for artificial sand.

[0026] In a preferred embodiment, there are two baffles 7 , an outer wall of one baffle 7 is fixedly equipped with a connecting rod, and one baffle 7 is fixedly connected to the outer wall of another baffle 7 via the connecting rod.

[0027] In the above structure, through the connection rod and baffle 7 structure, when the production materials are screened by the screen 4, the rough production materials will accumulate on the screen 4, and at this time, the two baffles 7 are both located in the box 1, so that the accumulated production materials cannot fall to the outside of the box 1. The user can drive the screw 13 to rotate through the motor 14, so that the slider 15 drives the baffle 7 to move synchronously, so that the accumulated production materials can move to the outside of the box 1 under the pushing action of the baffle 7, thereby facilitating the user to recycle the rough production materials, thereby improving the automation of the device and the user's maintenance efficiency of the device.

[0030] In a preferred embodiment, a limiting groove is provided on the inner wall of the box body 1, and the shape of the inner wall of the limiting groove matches the shape of the slider 15, and the outer wall of the slider 15 is slidably connected to the inner wall of the limiting groove.

[0031] In the above structure, by setting the limit groove structure, when the screw rod 13 is rotating, the limit groove can restrict the slider 15 so that the slider 15 cannot rotate with the screw rod 13, thereby ensuring that the slider 15 can drive the baffle 7 to move, thereby achieving the effect of automatically cleaning the stacked production materials, and improving the automation of the device.

[0032] Working principle: First, after the user assembles the device, he directly puts the production raw materials into the box 1 for grinding. After the ground production raw materials pass through two grinding rods, they fall on the screen 4. At this time, the user can drive the cam 3 to rotate through the screening motor 2 to make the screen 4 shake to screen the raw materials. Qualified raw materials will be directly discharged to the outside of the box 1. The user can collect the fallen qualified raw materials. Finally, the motor 14 drives the screw rod 13 to rotate so that the baffle 7 pushes the accumulated rough raw materials to the outside of the box 1, and the user can collect them.

[0033] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
