Description

Technical Field

[0001] The utility model relates to the technical field of vibration sorting machines, in particular to a grain vibration sorting machine. Background Art

[0002] The vibration separator uses vibration force and material characteristics to separate and classify materials. It separates materials of different specific gravities in the mixture to obtain the final desired material.

[0003] The core components of the vibration separator include the motor and the vibrator. After the motor is started, the vibrator generates periodic exciting force, causing the entire screening device to vibrate linearly or circularly.

[0004] In actual use, it can also be used in grain sorting. It is often used in some individual grain production, because the grain needs to be dried after shelling to ensure the dryness of the rice. Generally, the drying is done on the cement floor, which will cause stones or cement particles to be mixed in the rice particles, affecting the sale of rice. Therefore, it is particularly important to clean the impurities in the rice before selling it. However, the current vibration sorting machine uses a vibrating screen to complete the separation effect is not obvious, so there is an urgent need for a grain vibration sorting machine to achieve better sorting of rice, stones and cement particles. Utility Model Content

[0005] The utility model aims to provide a grain vibrating separator to solve the problem in the above background technology that the effect of separating grains only by using a vibrating screen is not obvious.

[0006] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0007] A grain vibration sorter comprises a shell, a vibration motor is fixedly installed inside the shell, a screening plate connected to the vibration motor is also arranged inside the shell, the screening plate comprises a sorting part and a feeding part, and the slope of the sorting part is smaller than the slope of the feeding part.

[0008] As a further solution of the utility model: wherein, the vibration motor includes a motor and a vibrator, the output end of the motor is connected to the vibrator, driving the vibrator to work and generate an exciting force, and the vibrator is installed below the screening plate.

[0009] As a further solution of the utility model: wherein, a cover plate is provided on the shell, and a feed port is provided on the cover plate, and the feed port is in the shape of an inverted cone.

[0010] As a further solution of the utility model: wherein, both sides of the screening plate are movably connected to the outer shell through connecting rods, and the connecting rods include a main rod rotatably connected to the inner wall of the outer shell, and a secondary rod rotatably connected to the side wall of the screening plate, and the main rod and the secondary rod are welded.

[0011] As a further solution of the utility model: wherein, a one-way stop is provided on the sorting part, and the one-way stop comprises an upwardly raised arc surface and a vertical end, and a screening hole is provided on the discharge part.

[0012] As a further solution of the utility model: wherein, a wind separator is arranged at the bottom of the sorting part, and the wind of the wind separator acts on the sorting part.

[0013] As a further solution of the utility model: wherein, a delivery channel is arranged above the screening plate, and the delivery channel is connected to the outside.

[0014] Compared with the prior art, the beneficial effects of the utility model are:

[0015] The exciting force generated by the screening plate will vibrate the grains and impurities. Because the stone has a high specific gravity and is difficult to move downward under the exciting force due to the raised arc surface design, the stone gradually moves upward through the one-way stop. In order to efficiently sort the rice and stone, a wind separator is provided at the bottom of the sorting part. The wind of the wind separator acts on the sorting part. The rice grains on the sorting part will be lifted up by the wind separator. With the action of the screening plate, the rice grains can easily pass over the vertical end of the one-way stop and gradually move downward. After the rice grains come to the feeding part, because the aperture of the screening hole is very small, it is easy to be sent downward under the action of gravity and exciting force. Thus, the effect of efficient grain separation is achieved. BRIEF DESCRIPTION OF THE DRAWINGS

[0024] See also Figure 1 , which is a schematic diagram of the overall structure of this embodiment, the device includes a housing 10, a vibration motor 11 is fixedly installed inside the housing 10, the vibration motor 11 includes a motor 111 and a vibrator 112, the output end of the motor 111 is connected to the vibrator 112, driving the vibrator 112 to work, thereby generating vibration; a cover plate with a feed port 20 is installed above the housing 10, the feed port 20 is an inverted cone, and the larger end of the feed port 20 can hold more grains at the same time. After the grains enter the feed port 20, because the diameter of the bottom discharge port is small, the speed at which the grains enter the inside of the sorting machine slows down, thereby achieving the effect of slowly adding materials to the inside of the sorting machine. It avoids the problem that a large amount of grains fall into the inside of the sorting machine, and the sorting machine has no time to sort, resulting in poor sorting effect.

[0025] like Figures 2 to 4 As shown, a screening plate 30 is further provided inside the housing 10, and both sides of the screening plate 30 are movably connected to the housing 10 through connecting rods 40, and the connecting rods 40 include a main rod 41 rotatably connected to the inner wall of the housing 10, and a secondary rod 42 rotatably connected to the side wall of the screening plate 30, and the main rod 41 and the secondary rod 42 are welded. Under the action of the vibration motor 11, the screening plate 30 will be driven to generate an exciting force inside the housing 10 under the action of the connecting rod 40. The vibration of the screening plate 30 is realized to complete the sorting of grains.

[0026] Furthermore, the vibrator 112 is installed at a low point below the screening plate 30. Compared with the vibrators installed at both ends of the screening plate 30, the vibrator 112 in this embodiment is installed at a more uniform position, and the screening effect is better.

[0027] Furthermore, the screening plate 30 includes a sorting portion 31 and a feeding portion 32, the slope of the sorting portion 31 is smaller than the slope of the feeding portion 32, and a one-way stop 311 is opened on the sorting portion 31, the one-way stop 311 includes an upwardly protruding arc surface 311a and a vertical end 311b, and a screening hole is provided on the feeding portion 32. In this embodiment, the exciting force generated by the screening plate 30 will vibrate the grains and impurities. Because the stone has a high specific gravity and is difficult to move downward under the exciting force due to the design of the raised arc surface 311a, the stone gradually moves upward through the one-way stop 311. In order to efficiently sort the rice and stone, a wind separator 50 is provided at the bottom of the sorting part 31. The wind of the wind separator 50 acts on the sorting part 31. The rice grains on the sorting part 31 will be lifted up by the wind separator 50. With the action of the screening plate 30, the rice grains can easily pass over the vertical end 311b of the one-way stop 311 and gradually move downward. After the rice grains come to the feeding part 32, because the aperture of the screening hole is very small, they can be easily sent downward under the action of gravity and exciting force. Thus, the effect of efficient grain separation is achieved.

[0028] Meanwhile, a delivery channel 33 is provided above the screening plate 30, and the delivery channel 33 is connected to the outside. In this embodiment, because the wind separator 50 generates wind force inside the housing, the wind force is discharged through the delivery channel 33, and then the stones after vibration sorting are discharged through the delivery channel 33 under the action of the wind, thereby achieving the effect of completing the discharge.

Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
