The sieve plate 3 is lower on the left and higher on the right, and the left end is lower than the lower end of the partition 2; the pushing member includes a horizontal plate 6, an n-type plate 7 and a pushing plate 8. The horizontal plate 6 is fixed to the lower end of the inner surface of the left side of the shell 1, and a vertical plate 9 located below the partition 2 is fixed to the right end of the top surface of the horizontal plate 6. The horizontal plate 6 and the vertical plate 9 are both rectangular plates. The front and rear ends and the lower end of the n-type plate 7 are open. The n-type plate 7 is stuck outside the vertical plate 9, and a plurality of springs 10 are connected between the inner top surface and the vertical plate 9. The outer right side surface of the n-type plate 7 slides in contact with the left end of the sieve plate 3. A baffle 11 is provided at the lower part of the outer left side surface of the n-type plate 7. The baffle 11 is a long rod body arranged along the length direction of the n-type plate 7. A hydraulic cylinder 12 is fixed on the cross plate 6. The piston end of the hydraulic cylinder 12 faces upward and is connected to a push plate 8. The push plate 8 is a rectangular plate. The push plate 8 is higher on the left and lower on the right, and the right end is opposite to the baffle 11 up and down.

[0023] An observation window 13 is provided at the lower part of the left side plate of the shell 1; a lower hopper 14 is connected to the lower end of the shell 1, and the lower hopper 14 is a hollow quadrangular platform with a larger upper part and a smaller lower part and openings at both ends; the upper end of the lower hopper 14 is connected to the lower end of the shell 1, and a discharge door 15 is provided at the opening at the lower end; and support legs 16 are provided on the outer wall of the lower hopper 14.

[0024] The front and rear ends of the horizontal plate 6 are fixedly connected to the front and rear inner surfaces of the shell 1 respectively, the right end of the horizontal plate 6 is flush with the left end of the screen plate 3, the front and rear ends of the vertical plate 9 are fixedly connected to the front and rear inner surfaces of the shell 1 respectively, the front and rear ends of the n-type plate 7 slide in contact with the front and rear inner surfaces of the shell 1, the inner side surface of the n-type plate 7 slides in contact with the vertical plate 9, the outer left side of the n-type plate 7 is flush with the left side of the partition 2, the front and rear ends of the push plate 8 slide in contact with the front and rear inner surfaces of the shell 1 respectively, and the left end of the push plate 8 slides in contact with the left inner surface of the shell 1.

[0025] The upper end surface of the partition 2 is an inclined surface which is higher on the left and lower on the right. When the hydraulic cylinder 12 drives the push plate 8 to move upward to the limit state, the top surface of the push plate 8 is flush with the upper end surface of the partition 2; the top surface of the guide plate 5 is flush with the upper end surface of the partition 2, and the right end of the guide plate 5 is located above the left grinding roller 4. A guide plate 22 is fixed on the right side plate of the shell 1. The guide plate 22 is a rectangular plate whose front and rear ends are fixedly connected to the front and rear inner surfaces of the shell 1. The guide plate 22 is lower on the left and higher on the right, and the left end is located above the right grinding roller 4.

[0026] The outer top surface of the n-type plate 7 is a slope that is lower on the left and higher on the right. The lower end surface of the partition 2 is a slope that is lower on the left and higher on the right. The outer top surface of the n-type plate 7 is parallel to the lower end surface of the partition 2. When the push plate moves downward to the limit state, the right end of the push plate presses the baffle bar downward to drive the n-type plate 7 to move, and the lower end contacts the top surface of the cross plate 6. The spring 10 is in a compressed state. The outer top surface of the n-type plate 7 is flush with the top surface of the sieve plate 3. When the outer top surface of the n-type plate 7 contacts the lower end surface of the partition 2, the spring 10 is in a natural state.

[0027] The front ends of the two grinding rollers 4 are connected to a rotating shaft 17, each rotating shaft 17 penetrates and is rotatably connected to the front side plate of the shell 1, the front ends of the two rotating shafts 17 are connected to gears 19, the two gears 19 are meshed, and the rear ends of the two grinding rollers 4 are rotatably connected to the rear side plate of the shell 1 via a rotating shaft 20. The rotating shaft 20 on the left side is driven to rotate by a motor 21, and the rear end of the rotating shaft 20 on the left side penetrates the rear side plate of the shell 1. A motor 21 is fixed on the outer rear side of the shell 1, and the output end of the motor 21 is connected to the rear end of the rotating shaft 20 on the left side.

[0028] When in use, close the discharge door 15, and the hydraulic cylinder 12 drives the push plate 8 to move downward. During the downward movement of the push plate 8, the right end of the push plate 8 presses the baffle 11 downward, and the baffle 11 drives the n-type plate 7 to move downward. The spring is compressed. Through the observation window 13, when the outer top surface of the n-type plate 7 is flush with the top surface of the sieve plate 3, the push plate 8 stops moving downward. At this time, there is a gap between the n-type plate 7 and the partition 2; start the motor 21, and the motor 21 drives the grinding roller 4 on the left to rotate clockwise. Since the front ends of the two grinding rollers 4 are meshed through the gear 19, the grinding roller 4 on the right rotates counterclockwise (the clockwise or counterclockwise rotation of the grinding roller 4 is Figure 1 main viewing angle);

[0029] The quartz sand to be ground is put into between the guide plate 1 5 and the guide plate 2 22. Under the guidance of the guide plate 1 5 and the guide plate 2 22, the quartz sand enters between the two grinding rollers 4 and is ground. The ground quartz sand falls onto the sieve plate 3. The quartz sand particles falling on the sieve plate 3 roll to the lower left along the inclined direction of the sieve plate 3. In the process of rolling of the quartz sand particles, the quartz sand particles smaller than the diameter of the sieve hole 18 on the sieve plate 3 fall into the lower hopper 14 through the sieve hole 18, and the quartz sand particles larger than the diameter of the sieve hole 18 of the sieve plate 3 roll to the lower left, pass between the n-type plate 7 and the partition plate 2, and fall between the push plate 8 and the n-type plate 7. The outer top surface of the n-type plate 7 is a slope with a lower left and a higher right, which is conducive to the rolling of the quartz sand particles. Through the observation window 13, when the quartz sand particles between the push plate 8 and the n-type plate 7 When the particles are accumulated close to the upper end of the n-type plate 7, the hydraulic cylinder 12 is started to drive the push plate 8 to move upward. When the push plate 8 moves upward, the spring 10 pushes the n-type plate 7 upward under the restoring force of the spring 10, and the baffle 11 keeps in contact with the right end of the push plate 8 until the outer top surface of the n-type plate 7 contacts the lower end surface of the partition 2. The push plate 8 continues to push the quartz sand particles on the upper side of the push plate 8 to move upward until the top surface of the push plate 8 is flush with the upper end surface of the partition 2. The quartz sand particles on the upper side of the push plate 8 are guided by the guide plate 5 and enter between the two grinding rollers 4 for secondary grinding. Therefore, driving the push plate 8 to reciprocate up and down can grind the large-diameter quartz sand particles again until they are ground to a diameter smaller than the sieve hole 18 on the sieve plate 3. After the grinding is completed, the discharge door 15 is opened to facilitate unloading.

Without violating the spirit of the present invention, i.e., the disclosure scope, any equivalent or equivalent deformation or replacement of the technical solution of the present invention shall fall within the protection scope of the present invention.
