[0021] When grinding the raw materials, the raw materials to be ground are put into the feed bin 11, and the raw materials fall into the grinding trough 7 through the feed bin 11, and then the grinding motor 8 is started to drive the rotating shaft 9 to rotate, and then the grinding disc 10 is driven to rotate in the grinding trough 7 through the rotating shaft 9, so that the raw materials in the grinding trough 7 are ground. A discharge port is opened at the bottom of the grinding trough 7, and the ground raw materials will pass through the discharge port and fall to the bottom of the grinding trough 7.

[0022] A screen 2 is obliquely provided in the grinding box 1, a U-shaped baffle 3 is fixedly installed on the screen 2, the screen 2 is horizontally slidably installed in the grinding box 1 through a supporting assembly, a moving hole is opened at the back of the grinding box 1, a moving block 4 is fixedly installed on the baffle 3, the moving block 4 is horizontally slidably installed in the moving hole, and one end of the moving block 4 passes through the moving hole, the grinding box 1 is provided with a transmission assembly for driving the moving block 4 to reciprocate, a mounting hole is opened on the side of the grinding box 1, a guide slot plate 5 is obliquely installed in the mounting hole, and one end of the guide slot plate 5 is located directly below the screen 2.

[0023] The supporting assembly includes two support rods 12 fixedly installed in the grinding box 1 and two sliders 13 horizontally slidably sleeved on the two support rods 12, the two sliders 13 are fixedly connected to the baffle 3, the screen 2 and the baffle 3 are installed in the grinding box 1 through the support rods 12 and the sliders 13, and the sliders 13 can slide on the support rods 12, so that when the sliders 13 slide back and forth on the support rods 12, the screen 2 can be driven to swing back and forth in the grinding box 1.

[0024] The screen 2 is installed obliquely in the grinding box 1, and the downwardly inclined end of the screen 2 is located directly above the outlet slot plate 5. The raw materials will fall on the screen 2 after being ground, and the raw materials will roll along the screen 2 toward the outlet slot plate 5. During the rolling process, the screen 2 screens the raw materials, and the raw materials that do not meet the requirements will automatically fall onto the outlet slot plate 5.

[0025] The transmission assembly includes a first rotating shaft 15 rotatably mounted on the side of the grinding box 1 through a first mounting block 14, a rotating disk 16 fixedly mounted at one end of the first rotating shaft 15, two hinged columns 17 respectively fixedly mounted on the rotating disk 16 and the moving block 4, a hinged rod 18 and a driving component for driving the first rotating shaft 15 to rotate, the two ends of the hinged rod 18 are respectively rotatably connected with the two hinged columns 17, the driving component includes a second rotating shaft 20 rotatably mounted on the side of the grinding box 1 through a second mounting block 19, a driving motor 21 fixedly mounted on the grinding box 1, a first bevel gear 22 fixedly sleeved on the second rotating shaft 20 and a second bevel gear 23 fixedly mounted at one end of the first rotating shaft 15, the first bevel gear 22 is meshedly connected with the second bevel gear 23, and the output shaft of the driving motor 21 is fixedly connected to one end of the second rotating shaft 20.

[0026] During the grinding process, the driving motor 21 is started to drive the second rotating shaft 20 to rotate, and then the first bevel gear 22 is driven to rotate through the second rotating shaft 20. Since the first bevel gear 22 is meshed and connected with the second bevel gear 23, the first rotating shaft 15 is driven to rotate through the second bevel gear 23. When the first rotating shaft 15 rotates, it drives the rotating disk 16 to rotate, and then the movable block 4 can be driven to reciprocate in the movable hole through the hinge column 17 and the hinge rod 18. When the movable block 4 reciprocates, it drives the screen 2 and the baffle 3 to swing back and forth in the grinding box 1. When the raw material falls on the screen 2, the swinging screen 2 can speed up the screening of the raw material, and at the same time, it is convenient for the raw material that does not meet the requirements on the screen 2 to move toward the direction of the outlet slot plate 5 to avoid the accumulation of raw materials on the screen 2, so that there is no need to disassemble the screen 2, the operation is simple, time-saving and labor-saving, and the grinding efficiency is effectively improved to ensure the screening effect of the screen 2.

[0027] A plurality of strip rods 24 are fixedly mounted on the screen 2, and the plurality of strip rods 24 are staggered and arranged on both sides of the screen 2. When the screen 2 swings back and forth, the raw materials will contact the strip rods 24 on both sides. The staggered strip rods 24 can extend the moving time of the raw materials when the raw materials move toward the guide slot 5, thereby lengthening the screening time of the raw materials, ensuring that the raw materials can be fully screened, and improving the screening effect of the screen 2.

[0028] A feeding barrel 26 is fixedly installed on the grinding box 1 through a supporting block 25, and a feeding pipe 27 is fixedly connected to the lower end of the feeding barrel 26, and one end of the guide slot plate 5 is inserted in the feeding pipe 27, and a guide pipe 28 is fixedly connected to the upper end of the feeding barrel 26, and one end of the guide pipe 28 extends into the grinding box 1 and is located above the grinding assembly. A feeding assembly for driving the raw material to move toward one end of the guide pipe 28 is provided in the feeding barrel 26, and the feeding assembly includes a rotating rod 29 vertically rotatably installed in the feeding barrel 26, a spiral blade 30 fixedly sleeved on the rotating rod 29, and a rotating component that drives the rotating rod 29 to rotate, one end of the rotating rod 29 passes through the feeding barrel 26, and the rotating component includes a first transmission wheel 31 fixedly sleeved on the rotating rod 29, a second transmission wheel 32 fixedly installed at one end of the second rotating shaft 20 and a transmission belt 33, and the transmission belt 33 is sleeved on the first transmission wheel 31 and the second transmission wheel 32.

[0029] One end of the guide slot plate 5 is inserted into the feed pipe 27, and the end of the guide pipe 28 away from the feeding barrel 26 is located directly above the grinding groove 7. When the raw material band that does not meet the requirements on the screen 2 falls on the guide slot plate 5, the raw material will enter the feeding barrel 26 through the feed pipe 27. When the driving motor 21 drives the second rotating shaft 20 to rotate, it will also drive the second transmission wheel 32 to rotate, and then drive the first transmission wheel 31 to rotate through the transmission belt 33. When the first transmission wheel 31 rotates, it will drive the rotating rod 29 to rotate, and at the same time drive the spiral blade 30 to rotate in the feeding barrel 26. When the spiral blade 30 rotates in the feeding barrel 26, it will drive the raw material in the feeding barrel 26 to move upward. When the raw material moves to one end of the guide pipe 28, it will enter the guide pipe 28 and fall into the grinding groove 7 again through the guide pipe 28. The raw material that does not meet the requirements is ground again until the raw material meets the requirements. The degree of automation is high, and no staff operation is required, which further improves the grinding efficiency.

[0030] In the present invention, during the grinding process, the ground raw materials will automatically fall onto the screen 2, and at the same time, the moving block 4 is driven by the transmission component to reciprocate in the moving hole. When the moving block 4 reciprocates, it drives the screen 2 and the baffle 3 to swing back and forth in the grinding box 1. When the raw materials fall on the screen 2, the swinging screen 2 can speed up the screening of the raw materials. At the same time, the tilted screen 2 facilitates the movement of raw materials that do not meet the requirements toward the guide slot 5 to avoid the accumulation of raw materials on the screen 2, so there is no need to disassemble the screen 2, the operation is simple, time and labor are saved, the grinding efficiency is effectively improved, and the screening effect of the screen 2 is guaranteed.
