[0026] Please refer to Figure 1 , Figure 2 and Figure 6The organic fertilizer screening device comprises a frame 1, a screening frame 2 movably arranged on the frame 1 in a horizontal direction and a screening net 3 arranged in the screening frame 2, and a movable plate 21 arranged on opposite sides of the screening frame 2 respectively, a sliding groove 11 arranged on the frame 1 and matched with the movable plate 21, the sliding groove 11 being used to limit the moving direction of the screening frame 2 on the frame 1, a slot 22 arranged on the movable plate 21 and a transmission rod 4 arranged in the slot 22, arc-shaped grooves 41 arranged on opposite ends of the transmission rod 4 respectively and the centers of the two arc-shaped grooves 41 coinciding, a first protrusion 23 arranged on the inner wall of the slot 22 and matched with the arc-shaped grooves 41, the transmission rod 4 being able to rotate around the center of the arc-shaped grooves 41 in the slot 22, a rotatable eccentric wheel 5 arranged on the frame 1 and a driving assembly 6 in transmission connection with the eccentric wheel 5, a through hole 42 arranged on the transmission rod 4 and matched with the eccentric wheel 5 and close to one end of the transmission rod 4, a knocking assembly 7 arranged on the screening frame 2, the knocking assembly 7 comprising a connecting rod 71 and a knocking block 72 arranged on the connecting rod 71, the connecting rod 71 being matched with the transmission rod 4 one by one at both ends respectively and the connecting rod 71 being arranged at intervals with the center of the arc-shaped grooves 41 at the connecting position of the connecting rod 71 and the transmission rod 4, and the knocking block 72 being arranged below the screening net 3. When the driving assembly 6 drives the eccentric wheel 5 to rotate, the transmission rod 4 is driven to move, the transmission rod 4 and the movable plate 21 move reciprocatingly on the frame 1 in a horizontal direction, the screening frame 2 and the screening net 3 are shaken in a horizontal direction, the transmission rod 4 is driven to rotate reciprocatingly in the slot 22 when the eccentric wheel 5 rotates, the connecting rod 71 connected with the transmission rod 4 is driven to move and the knocking block 72 is driven to approach or move away from the screening net 3, and the knocking block 72 collides with the screening net 3 when the knocking block 72 approaches the screening net 3, so that the screening net 3 is shaken.

[0027] Specifically, the operation steps of screening the organic fertilizer by using the organic fertilizer screening device are as follows: the organic fertilizer to be screened is poured into the screening frame 2, and then the driving assembly 6 is started after the organic fertilizer falls on the screening net 3; the eccentric wheel 5 rotates under the driving of the driving assembly 6 and drives the transmission rod 4 and the movable plate 21 to move reciprocatingly along the horizontal direction on the rack 1, so that the screening frame 2 and the screening net 3 shake along the horizontal direction to accelerate the organic fertilizer in the screening frame 2 to pass through the screening net 3, and the screening of the organic fertilizer is realized; the eccentric wheel 5 rotates and simultaneously drives the transmission rod 4 to rotate reciprocatingly around the center of the arc-shaped slot 41 in the slot 22; the transmission rod 4 rotates and drives the connecting rod 71 to rotate around the center of the arc-shaped slot 41, so that the knocking block 72 approaches or moves away from the screening net 3; when the knocking block 72 approaches the screening net 3, the knocking block 72 collides with the screening net 3 to shake the screening net 3; with the shaking of the screening net 3, the organic fertilizer particles stuck in the mesh of the screening net 3 or adhered to the screening net 3 are separated from the screening net 3, so that the mesh of the screening net 3 is prevented from being blocked, and the screening net 3 can be automatically cleaned.

[0029] Please refer to Figure 2 and Figure 3The screening frame 2 is provided with vertical guide rods 25, and the screening net 3 is provided with guide holes matched with the guide rods 25. The guide rods 25 are sleeved with springs 26, and the springs 26 abut against the screening net 3 away from the knocking assembly 7. The guide rods 25 on the screening frame 2 are matched with the guide holes on the screening net 3, and the guide rods 25 are sleeved with the springs 26 abutting against the screening net 3. When the screening net 3 collides with the knocking block 72 to shake, the screening net 3 slides on the guide rods 25, and the springs 26 stretch and contract with the movement of the screening net 3, so that the screening net 3 can float relative to the screening frame 2 after being impacted, avoiding the knocking block 72 and the screening net 3 from colliding with each other to deform or damage the screening net 3, thereby improving the reliability of the organic fertilizer screening device.

[0030] As shown in Figure 1 , Figure 5 and Figure 6 , the driving assembly 6 comprises a driving rod 61 rotatably arranged on the rack 1 and a motor 62 in transmission connection with the driving rod 61. The driving rod 61 is provided with two first sprockets 63 at intervals. The eccentric wheel 5 is provided with a connecting shaft 51, and the connecting shaft 51 is sleeved with a second sprocket 52. The first sprocket 63 and the second sprocket 52 are in transmission connection through a first transmission chain 64. When the driving rod 61 rotates under the drive of the motor 62, the power output by the motor 62 is transmitted to the eccentric wheel 5 through the cooperation of the first sprocket 63, the first transmission chain 64 and the second sprocket 52, so that the eccentric wheel 5 rotates under the drive of the motor 62. The two ends of the driving rod 61 are respectively provided with the first sprocket 63, so that the two eccentric wheels 5 located at the two ends of the screening frame 2 rotate synchronously, which is beneficial to improve the stability of the screening frame 2 when moving on the rack 1.

[0031] In detail, the output end of the motor 62 is provided with a third sprocket 65, the driving rod 61 is sleeved with a fourth sprocket 66, and the third sprocket 65 and the fourth sprocket 66 are in transmission connection through a second transmission chain 67.

[0032] Please refer to Figure 2 and Figure 4The plurality of knocking blocks 72 are arranged on the connecting rod 71 at equal intervals along the axial direction of the connecting rod 71. By arranging the plurality of knocking blocks 72 on the connecting rod 71 at equal intervals, the different positions of the screening net 3 are knocked respectively, so that the organic fertilizer particles in different meshes or the organic fertilizer adhered to different positions can be shaken off when the screening net 3 is shaken, and the mesh of the screening net 3 on the organic fertilizer screening device during operation is kept unblocked.

[0033] In the embodiment, the cross section of the knocking block 72 is triangular, and the width of the knocking block 72 gradually increases in the direction away from the screening net 3. The cross section of the knocking block 72 is triangular, so that the organic fertilizer falling on the knocking block 72 through the screening net 3 continues to fall along the side surface of the knocking block 72, avoiding the product loss caused by the organic fertilizer falling on the knocking block 72 and staying on the knocking block 72.

[0034] As shown in Figure 4 The knocking assembly 7 comprises two connecting rods 71 arranged at intervals, and the connecting positions of the two connecting rods 71 and the same transmission rod 4 are located on the opposite sides of the center of the arc-shaped groove 41. The two connecting rods 71 are connected on the same transmission rod 4, and the knocking blocks 72 are arranged on each connecting rod 71 respectively, and the two connecting rods 71 are located on the two sides of the center of the arc-shaped groove 41 respectively. When the transmission rod 4 rotates under the drive of the eccentric wheel 5, the two connecting rods 71 rotate in opposite directions around the center of the arc-shaped groove 41 respectively, so that the knocking blocks 72 on the two connecting rods 71 collide with the screening net 3 respectively, which is beneficial to improve the cleaning effect of the knocking assembly 7.
