DETAILED DESCRIPTION

[0020] In order to make the purpose, technical solutions and advantages of the embodiments of the utility model clearer, the technical solutions in the embodiments will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. The following embodiments are used to illustrate the utility model but are not used to limit the scope of the utility model.

[0021] Embodiment 1:

[0022] Reference Figure 1-Figure 4 The premix particle screening device includes a collecting box 1, and also includes: a support rod 101, which is vertically fixedly connected to the collecting box 1; a screening box 2, which is rotatably connected to the upper end of the support rod 101; two groups of screening holes are symmetrically opened at the bottom of the screening box 2; a bracket 3, which is fixedly connected to the collecting box 1 and is located on the outside of the screening box 2; two eccentric disks 303 are staggered and symmetrically rotated on both sides of the opening end of the screening box 2; a driving component for driving the eccentric disk 303 to rotate, which is installed on the bracket 3.

[0023] The driving assembly includes a rotating rod 301 and a motor 302. The rotating rod 301 is rotatably connected to the bracket 3. The motor 302 is fixedly connected to one side of the bracket 3. The output end of the motor 302 is fixedly connected to one end of the rotating rod 301. Two eccentric disks 303 are symmetrically fixedly connected to the rotating rod 301.

[0024] When the production of the premix is ​​completed and the premix particles need to be screened out from the mixture of the premix powder and the particles, the mixture of the premix powder and the particles can be poured into the screening box 2, and then the motor 302 can be started. The motor 302 will drive the two eccentric disks 303 to rotate through the rotating rod 301. Since the two eccentric disks 303 are slidably attached to both sides of the upper end of the screening box 2 and are staggered, when the rotating rod 301 drives the two staggered eccentric disks 303 to rotate, the two eccentric disks 303 will drive the screening box 2 to rotate and tilt back and forth with the cooperation of the support rod 101, thereby driving the premix powder and the particle mixture in the screening box 2 to move back and forth left and right, and then the premix powder and the particle mixture in the screening box 2 can be moved back and forth left and right. The powder in the mixture of mixed powder and particles will fall into the collecting box 1 through the screening holes of the screening box 2 for collection, while the premix particles will remain in the screening box 2, thereby completing the screening operation of the premix particles. After the separation of the premix powder and the particles is completed, an external negative pressure suction feeder can be used to extract the premix powder in the collecting box 1 and the premix particles in the screening box 2 for classified storage. Compared with the operation of separating and screening the premix powder and the particle mixture by vibration in the prior art, the device can reduce the amount of premix powder lifted, which is not only convenient for better screening of the premix particles, but also convenient for collecting the premix powder, effectively improving the practicability of the device.

[0025] Embodiment 2:

[0026] Reference Figure 1-Figure 4 , the premix particle screening device is basically the same as that of Example 1, and further, the rotating rod 301 is a reciprocating screw rod, and a moving block 304 is threadedly connected to the rotating rod 301, and the lower end of the moving block 304 is symmetrically fixedly connected with a tensioning telescopic rod 306, and the lower ends of the two tensioning telescopic rods 306 are fixedly connected with rake teeth 307, and the upper end of the moving block 304 is fixedly connected with a T-shaped rod 305, and a T-shaped slot used in conjunction with the T-shaped rod 305 is provided on the bracket 3. When the rotating rod 301 drives the two eccentric disks 303 to rotate, it can also drive the moving block 304 to reciprocate left and right through the reciprocating thread and with the cooperation of the T-shaped rod 305, and then the moving block 304 can drive the rake teeth 307 to reciprocate left and right in the screening box 2 through the tensioning telescopic rod 306, so that the premix particles can be reversely dialed, so that the premix powder in the premix particles can more fully pass through the screening hole and fall into the collecting box 1, effectively improving the screening efficiency of the premix particles.

[0027] The racks in the rake teeth 307 are rubber strips. By making the racks on the rake teeth 307 from rubber material, when the rake teeth 307 move back and forth in the screening box 2, the rake teeth 307 can be prevented from damaging the premix particles, thereby effectively improving the protection effect on the premix particles.

[0028] Embodiment 3:

[0029] Reference Figure 1-Figure 4 The premix particle screening device is basically the same as Example 2, and furthermore, two groups of fixed bars 4 are symmetrically arranged at the bottom of the screening box 2, and a plurality of fixed rods 401 are fixedly connected between each group of two fixed bars 4, and a plurality of dredging rods 402 are fixedly connected to the fixed rods 401 at equal intervals, and each dredging rod 402 is respectively located directly below each screening hole, and the diameter of the dredging rod 402 is smaller than the diameter of the screening hole, and a tension spring 403 is symmetrically fixedly connected to the fixed bar 4, and the upper end of the tension spring 403 is fixedly connected to the bottom of the screening box 2, and a limit rod 404 is symmetrically slidably connected to the fixed bar 4, and the upper end of the limit rod 404 is fixedly connected to the bottom of the screening box 2, and a pull rope 405 is fixedly connected to the fixed rod 401 located in the middle position, and the lower end of the pull rope 405 is fixedly connected to the bottom of the collecting box 1. When the screening box 2 rotates and tilts to the left, the right The left side will gradually become higher. Since a pull rope 405 is connected between the fixed rod 401 and the collecting box 1, when the right side of the screening box 2 rises upward, the pull rope 405 will stretch the tension spring 403 through the fixed bar 4, and then the dredging rod 402 will be pulled out of the screening hole of the screening box 2. When the screening box 2 rotates and tilts to the right, the left side will gradually become higher. The dredging rod 402 on the left will leave the screening hole on the left, and the tension spring 403 on the right will return to its position as the right pull rope 405 continues to loosen, thereby driving the dredging rod 402 on the right to be reinserted into the screening hole on the right. Repeatedly, while screening the premix particles, the screening holes can also be dredged to prevent some premix particles from blocking the screening holes and affecting the falling of the powdered premix, thereby effectively improving the efficiency of screening the premix particles.

[0030] The surface of the limiting rod 404 is smooth. By making the surface of the limiting rod 404 smooth, the friction between the limiting rod 404 and the opening opened on the fixing bar 4 can be reduced, so that the fixing bar 4 can drive the dredging rod 402 to move downward more smoothly.

[0031] The above description is only a preferred embodiment of the present invention and does not limit the present invention in any form. Although the present invention has been disclosed as a preferred embodiment, it is not intended to limit the present invention.
