Technical Field

[0001] The utility model relates to the technical field of vibrating screens, in particular to a vibrating screen machine for fertilizer processing. Background Art

[0002] In the process of fertilizer production, there are strict requirements on the size of fertilizer particles, so fertilizer screening is an indispensable process in fertilizer production. This process is usually completed by a screening machine.

[0003] At present, a vibrating screen is usually used for screening particulate matter. The vibrating screen in the prior art usually includes a screen body for storing materials. A base is provided at the bottom of the screen body. A vibration motor and a spring are provided between the base and the screen body to allow the screen body to shake up and down or left and right. After shaking, fertilizer particles with a particle volume smaller than the mesh aperture on the screen body fall onto the base, and fertilizer particles with a particle volume larger than the mesh aperture remain in the screen body.

[0004] In the case where fertilizer particles in the fertilizer pile are stuck together due to the humid environment, the vibrating screen needs to work for a long time before it can separate the clumped and stuck particles, and then screen the separated particles, which seriously affects the screening efficiency.

[0018] In summary, the utility model mainly has the following beneficial effects:

[0019] By setting up a screening box, when in use, the operator can place the fertilizer particles that need to be screened in the screening box and start the vibration motor. When the vibration motor works, the centrifugal force generated by the high-speed rotation of its rotating shaft and eccentric block obtains the exciting force, so that the screening box can produce a short-distance vertical linear movement. When the screening box moves downward toward the base, the position of the rotating shaft can be moved by the moving parts. The rotating shaft moves in translation along the screening box.

The arc-shaped pressing plate can exert a certain force on the particles on the net that are clumped together due to adhesion, so that the clumping can be broken up. With the continuous vibration of the screening box, the rotating shaft can complete a stroke of movement in the screening box, and the clumping in the screening box can be more comprehensively broken up. Compared with the screening box in the prior art, the present application can effectively improve the screening efficiency and solve the problem that the vibrating screen needs to work for a long time before it can separate the clumped and adhered particles, and then screen the separated particles, which seriously affects the screening efficiency.

[0033] A rotating shaft 103 is disposed in the screening box 100, and a plurality of arc-shaped pressing sheets 104 are disposed outside the rotating shaft 103;

[0034] A vibration motor 105 disposed at the bottom of the screening box 100;

[0035] A moving part disposed between the screening box 100 and the rotating shaft 103, the moving part can move the position of the rotating shaft 103 when the vibration motor 105 works to allow the screening box 100 to move toward the base 101, the rotating shaft 103 moves translationally along the base 101, and the rotating shaft 103 can also generate rotational motion during the translational motion;

[0036] By setting up the screening box 100, when in use, the operator can place the fertilizer particles that need to be screened in the screening box 100, and start the vibration motor 105. When the vibration motor 105 works, the centrifugal force generated by the high-speed rotation of the rotating shaft 103 and the eccentric block obtains the exciting force, so that the screening box 100 can produce a short-distance vertical linear movement. When the screening box 100 moves downward toward the base 101, the position of the rotating shaft 103 can be moved by the moving parts. The rotating shaft 103 moves in translation along the screening box 100. When the rotating shaft 103 moves in a straight line, it can also make a rotational movement, so that the arc on it can be made to move in the process of translation and rotation of the rotating shaft 103. The pressing sheet 104 can contact the particles on the screening net 102 that are clumped together due to adhesion. The arc-shaped pressing sheet 104 can exert a certain force on the clumping materials so that the clumping materials can be crushed. With the continuous vibration of the screening box 100, the rotating shaft 103 can complete a stroke of movement in the screening box 100, and the clumping materials in the screening box 100 can be crushed more comprehensively. Compared with the screening box 100 in the prior art, the present application can effectively improve the screening efficiency and solve the problem that the vibrating screen needs to work for a long time before it can separate the clumped and adhered particles and then screen the separated particles, which seriously affects the screening efficiency.

[0037] As a further feature of the present invention, the moving parts include slide rails 200 slidably connected to both sides of the screening box 100, the rotating shaft 103 is connected to the slide rails 200, the slide rails 200 are connected to a connecting frame 201, both sides of the screening box 100 are rotatably connected to reciprocating screw rods 202 threadedly connected to the connecting frame 201, the reciprocating screw rods 202 are connected to a first gear 203, and the base 101 is connected to a first rack 204 meshing with the first gear 203;

[0038] By setting the first gear 203, when the screening box 100 moves downward due to the action of the vibration motor 105, the first gear 203 can rotate under the influence of the first rack 204. The first gear 203 allows the reciprocating screw 202 to rotate, and the connecting frame 201 and the slide rail 200 can move through the force of the thread, thereby achieving the purpose of allowing the rotating shaft 103 to perform translational movement along the screening box 100.

[0041] As a further feature of the present invention, the moving part further includes a connecting shaft 300 connected to the slide rail 200, a shield 301 is connected between the connecting shaft 300 and the rotating shaft 103, the rotating shaft 103 is rotatably connected in the shield 301, a chain transmission mechanism 302 is connected between the connecting shaft 300 and the rotating shaft 103, the chain transmission mechanism 302 is arranged in the shield 301, the two ends of the connecting shaft 300 are respectively connected to the second gear 303, and the two sides of the screening box 100 are respectively connected to the second rack 304 meshing with the second gear 303;

[0042] By setting the second gear 303, when the reciprocating screw 202 rotates to move the slide rail 200, the slide rail 200 can drive the connecting shaft 300 and the shield 301 to move, and the movement of the shield 301 can drive the rotating shaft 103 connected to the bottom thereof to move. When the connecting shaft 300 makes a translational movement, the meshing of the second gear 303 and the second rack 304 can allow the second gear 303 and the connecting shaft 300 to rotate when the connecting shaft 300 and the second gear 303 translate, and the rotating shaft 103 can be rotated through the chain transmission mechanism 302, thereby achieving the purpose of rotating the rotating shaft 103.

[0043] As a further feature of the present invention, the rotating shaft 103 is externally connected to a ring body 400 , and a first spring telescopic rod 401 is connected between the ring body 400 and the arc-shaped pressing sheet 104 ;

[0044] By providing the first spring telescopic rod 401, when the rotating shaft 103 rotates to allow the arc-shaped pressing piece 104 to compress the clumped fertilizer particles, the first spring rod can adapt to the volume of the clumped fertilizer particles, while ensuring that the clumped fertilizer particles can be compressed and dispersed, the arc-shaped pressing piece 104 can avoid the problem of crushing the particles due to a large force.

[0045] As a further feature of the present invention, a second spring telescopic rod 402 is connected between the base 101 and the screening box 100;
