[0026] Please refer to Figure 1 - Figure 5 As shown in the figure, this embodiment provides a screening assembly for raw materials in cement product manufacturing, including a screening box body 1 and a feeding box body 2. A screening frame 3 is arranged at the upper end of the inner wall of the screening box body 1. A screening net 4 is fixedly connected inside the screening frame 3 through a fixing component. The screening net 4 is inclined. A control component for controlling the up and down swing of the screening frame 3 is arranged inside the screening box body 1;

[0027] Two rotating rods 5 are rotatably connected to the lower surface of the screening frame 3 through connecting blocks. Movable sleeves 6 are fixedly sleeved on the outer parts of the two rotating rods 5. A plurality of flapping rods 7 are fixedly connected to the outer walls of the two movable sleeves 6. A plurality of rubber bumps 8 are fixedly connected to the outer walls on both sides of the plurality of flapping rods 7;

[0028] Reserved grooves 9 for the two rotating rods 5 to move are opened on the outer wall of the screening box body 1. The two rotating rods 5 are connected by a belt and belt pulleys. A C-shaped sliding block 10 is arranged on the outer wall of the screening box body 1. Sliding grooves 11 for the two ends of the C-shaped sliding block 10 to slide are opened on the outer wall of the screening box body 1. A first motor 12 is fixedly installed on the outer wall of the C-shaped sliding block 10. The output end of the first motor 12 is fixedly connected to one of the rotating rods 5;

[0029] Among them, a movable through groove for the belt to move is opened on the side wall of the C-shaped sliding block 10.

[0030] The above working principle: When in use, the raw materials to be screened are put into the feeding box body 2, so as to convey the raw materials to the screening mesh 4 of the screening frame 3. At the same time, under the control of the control component, the screening frame 3 can be controlled to move up and down, so that the screening mesh 4 can filter and screen the raw materials, enabling the qualified raw materials to fall below the screening mesh 4, while the unqualified raw materials can be discharged along the inclined screening mesh 4. After the raw material screening is completed, the first motor 12 can be started to drive one of the rotating rods 5 to rotate. With the cooperation of the belt and the pulley, the other rotating rod 5 can be driven to rotate simultaneously, so that the movable sleeves 6 outside the two rotating rods 5 can rotate, and drive the rubber bumps 8 on the plurality of flapping rods 7 to contact the lower surface of the screening mesh 4, flapping the screening mesh 4, and discharging the raw materials stuck in the mesh holes of the screening mesh 4, thereby preventing screening blockage from occurring during the next screening work, which affects the screening and filtering effect and efficiency of the screening mesh 4 on the raw materials. The cooperation of the C-shaped sliding block 10, the sliding groove 11 and the reserved groove 9 is provided to ensure that the control component will not be restricted when controlling the screening frame 3 to move up and down.

[0031] In order to facilitate driving the screening frame 3 to move downward, the control component includes a driving rod 13. The two driving rods 13 are rotatably connected to the inner wall of the screening box body 1. The outer walls of the two driving rods 13 are fixedly sleeved with cams 14. The outer wall of the cam 14 abuts against the upper surface of the screening frame 3. A second motor 15 is fixedly installed on the outer wall of the screening box body 1. The output end of the second motor 15 is fixedly connected to one of the driving rods 13. The two driving rods 13 are传动连接通过皮带配合皮带轮. When in use, the second motor 15 is started to drive one of the driving rods 13 to rotate. With the cooperation of the belt and the pulley, the other driving rod 13 can be driven to rotate, so that the cams 14 on the two driving rods 13 can push the screening frame 3 to move downward during the rotation process, facilitating the up and down swing of the screening frame 3.

[0032] Considering that it is necessary to ensure the effect of the up and down movement of the screening frame 3, control blocks 16 are symmetrically and fixedly connected to the front and rear ends of the screening frame 3. Control grooves 17 for the control blocks 16 to move are opened on the inner wall of the screening box body 1. A return spring 18 is fixedly connected to the inner wall of the control groove 17. The other end of the return spring 18 is fixedly connected to the lower surface of the control block 16. Guide rods 19 are fixedly connected to the inner walls of the plurality of control grooves 17. Guide grooves adapted to the guide rods 19 are opened inside the control blocks 16. The return spring 18 is movably sleeved outside the guide rods 19. After the cam 14 pushes the screening frame 3 to move downward, under the elastic force of the return spring 18, the plurality of control blocks 16 can drive the screening frame 3 to move upward, completing one up and down movement of the screening frame 3, ensuring the effect of the up and down movement of the screening mesh 4 in the screening frame 3, and ensuring the screening effect of the screening mesh 4 on the raw materials.

[0033] For the convenience of replacing and cleaning the screening mesh 4, the fixing assembly includes a positioning block 20. A sliding groove for the positioning block 20 to slide is provided on the inner wall of the screening frame 3. The positioning block 20 abuts against the upper surface of the screening mesh 4. Clamping blocks 21 are symmetrically rotatably connected to the upper surface of the screening frame 3. The lower surface of the clamping block 21 abuts against the upper surface of the positioning block 20. A limiting block 22 is fixedly connected to the downwardly inclined end of the screening mesh 4. A limiting groove corresponding to the limiting block 22 is provided on the inner wall of the screening frame 3. The screening box body 1 and the feeding box body 2 are fixedly connected by a plurality of fixing screws 23 and nuts 24. During use, the plurality of fixing screws 23 can be rotated first to release the connection between the screening box body 1 and the feeding box body 2. Then, the limiting block 22 can be rotated to release the limitation on the position of the positioning block 20. Then, the positioning block 20 can be taken out of the screening frame 3 to release the fixation of the upwardly inclined end of the screening mesh 4, so as to facilitate taking out the screening mesh 4 from the screening frame 3 for replacement.

[0034] During operation, it is convenient to send the raw materials to be screened into the screening frame 3. Therefore, a feeding port 25 is provided on the upper surface of the feeding box body 2. An inclined plate 26 is inclinedly arranged directly below the feeding port 25. A U-shaped diversion block 27 is fixedly connected to the inner wall of the feeding box body 2. The U-shaped diversion block 27 is arranged below the downwardly inclined end of the inclined plate 26. After the raw materials to be screened are put into the feeding port 25, the raw materials can move downward through the inclined plate 26 and finally fall on the screening mesh 4 in the screening frame 3 after passing through the U-shaped diversion block 27. The provided U-shaped diversion block 27 can prevent the raw materials from falling into the gap between the screening frame 3 and the inner wall of the screening box body 1 during falling, which affects the movement of the screening frame 3. At the same time, the provided inclined plate 26 can prevent dust from overflowing from the feeding port 25 when screening the raw materials.

[0035] In addition, it is necessary to collect the qualified and unqualified raw materials after screening. Therefore, a V-shaped discharge plate 28 is arranged below the downwardly inclined end of the screening mesh 4. A guide plate 29 is fixedly connected to the lower surface of the screening frame 3. An activity groove for the V-shaped discharge plate 28 to move is provided inside the guide plate 29. A discharge port 30 is provided on the outer wall of the screening frame 3. A discharge groove 31 corresponding to the V-shaped discharge plate 28 is provided on the side wall of the screening box body 1. A collection box 32 is slidably connected to the lower end of the screening box body 1. The qualified raw materials after screening will fall into the collection box 32 for storage, while the unqualified raw materials will pass through the discharge port 30 and be discharged from the discharge groove 31 through the V-shaped discharge plate 28, which is convenient for subsequent processing of the qualified and unqualified raw materials.
