[0018] In order to deepen the understanding of the present invention, the present invention will be further described in detail below in conjunction with an embodiment. The embodiment is only used to explain the present invention and does not constitute a limitation on the protection scope of the present invention.

[0019] according to Figure 1 , 2 As shown in Figures 3 and 4, this embodiment proposes a vibrating cleaning screen for grain processing, including a base 1, a fixing frame 2 and a feeding hopper 3, the outer side of the base 1 is fixedly connected with the fixing frame 2, the top of the fixing frame 2 is fixedly connected with the feeding hopper 3, a guide bin 4 is provided above the base 1, the top of the guide bin 4 is fixedly connected with a screening bin 5 through a connecting plate 7, a vibrating screening mechanism is provided between the base 1 and the guide bin 4, grains are poured into the inside of the feeding hopper 3, the grains slide along the inner wall of the feeding hopper 3 to the inside of the screening bin 5, the vibrating screening mechanism drives the guide bin 4 and the screening bin 5 to vibrate, so that the grains fall through the screening bin 5 to the guide bin 4 and are discharged outward, while the straw is trapped in the screening bin 5 and discharged outward, so as to separate the grains from the straw, and avoid the problem that the straw mixed in the grains will aggravate their corruption and greatly reduce the value of the grains.

[0020] The vibration screening mechanism includes a base 8, a vibration motor 9 and an elastic spring 10. The bottom of the guide bin 4 is fixedly connected to the base 8, one side of the base 8 is provided with an inclined surface, and the vibration motor 9 is symmetrically fixedly installed on the inclined surface. The two sides of the bottom of the guide bin 4 are symmetrically fixedly connected with elastic springs 10, the bottom of the elastic spring 10 is fixedly connected to the top of the base 1 by bolts, and a group of adjustable eccentric blocks are installed at each end of the rotor shaft of the vibration motor 9. A mounting seat is provided on the outside of the vibration motor 9, and the mounting seat is detachably connected to the base 8 by bolts. The vibration motor 9 obtains an exciting force by the centrifugal force generated by the high-speed rotation of the shaft and the eccentric block, so as to drive the guide bin 4 and the screening bin 5 to vibrate. When the guide bin 4 and the screening bin 5 vibrate, the elastic spring 10 will be driven to deviate, and the elastic force generated by the elastic spring 10 itself is used to drive the guide bin 4 and the screening bin 5 to reset, so as to maintain a stable amplitude for the guide bin 4 and the screening bin 5.

[0021] A screen 6 is fixedly connected to the bottom of the screening bin 5, and a supporting groove 15 is provided on one side of the screening bin 5. One end of the supporting groove 15 is communicated with one side of the screen 6, and one side of the screening bin 5 is inclined toward the supporting groove 15. The grains pass through the sieve holes on the screen 6 and enter the interior of the guide bin 4. The grains are removed from the device through an outlet on one side of the guide bin 4, and the straw is retained on the surface of the screening bin 5. The screening bin 5 drives the straw to move toward the supporting groove 15 to remove the straw from the device.

[0022] Telescopic rods 11 are symmetrically arranged on both sides of the elastic spring sheet 10, and the top and bottom ends of the telescopic rods 11 are symmetrically hinged with hinge seats 12. The top and bottom ends of the telescopic rods 11 are fixedly connected to the material guide bin 4 and the base 1 respectively through the hinge seats 12. A nylon pad 16 is arranged inside the telescopic rod 11, and a spring 13 is arranged on the outside of the telescopic rod 11. The diameter of the spring 13 is smaller than the diameter of the hinge seat 12. The base 1 and the base 1 are connected together through the telescopic rod 11 and the hinge seat 12. When the telescopic rod 11 is extended or retracted, it will rub against the nylon pad 16 to generate friction force, which is used to consume the kinetic energy generated by the material guide bin 4 and the screening bin 5, and the elastic force generated by the spring 13 drives the material guide bin 4 and the screening bin 5 to reset. Under the premise of cooperating with the elastic spring sheet 10, the amplitude of the material guide bin 4 and the screening bin 5 is more stable.

[0023] A baffle 14 is provided on one side of the feeding hopper 3, and a rectangular slot is provided on one side of the feeding hopper 3. Both sides of the baffle 14 are engaged with the inner wall of the rectangular slot. When there are enough grains on the screening bin 5, the baffle 14 can be inserted into the rectangular slot. The baffle 14 blocks the outlet on one side of the feeding hopper 3 to prevent the grains from sliding onto the screen 6 and affecting the screening effect of the device. When the grains on the screening bin 5 are reduced to a certain amount, the baffle 14 is pulled out of the rectangular slot to allow the grains to continue to slide onto the screening bin 5.

[0024] The vibrating cleaning screen for grain processing uses a vibrating motor 9 that utilizes the centrifugal force generated by the high-speed rotation of the shaft and the eccentric block to obtain an exciting force, which is used to drive the guide bin 4 and the screening bin 5 to vibrate, and at the same time drive the elastic spring 10 to deviate, and utilize the elastic force generated by the elastic spring 10 itself to drive the guide bin 4 and the screening bin 5 to reset, so as to maintain a stable amplitude for the guide bin 4 and the screening bin 5, and the grain passes through the sieve holes on the screen 6 into the interior of the guide bin 4, and the grain is removed from the device through an outlet on one side of the guide bin 4, while the straw is trapped on the surface of the screening bin 5, and the screening bin 5 drives the straw to move toward the direction of the supporting trough 15, and removes the straw from the device, so as to separate the grain from the straw, and avoid the problem that the straw is mixed in the grain, which will aggravate its corruption and greatly reduce the value of the grain.
