Description

Technical Field

[0001] This utility model relates to the field of grain cleaning technology, specifically a grain vibrating cleaning screen. Background Technology

[0002] Grains encompass a variety of grains, including rice, wheat, millet, soybeans, and other miscellaneous grains. A grain vibrating cleaning screen is a device used to clean and screen grains, effectively removing impurities and improving grain quality.

[0003] However, most existing vibrating cleaning screens for grains clean and screen grains by setting up a screen inside the screen box. However, they cannot perform continuous vibrating screening. They can only screen grains after the grains on the screen have been screened, which greatly reduces the screening efficiency. Utility Model Content

[0005] To achieve the above objectives, this utility model provides the following technical solution: a grain vibrating cleaning screen, comprising an outer shell, a servo motor mounted on the outer wall of one end of the outer shell via a fixed frame, the output end of the servo motor being fixedly connected to a drive shaft via a coupling, the other end of the drive shaft movably passing through the outer shell, a driven shaft being rotatably inserted into the inner wall of the outer shell away from the drive shaft, transmission rollers being fixedly sleeved on the shaft walls of both the driven shaft and the drive shaft, the two transmission rollers being connected by a transmission belt, a plurality of screen holes being equally spaced through the outer wall of the transmission belt, an inclined plate being provided between the two transmission rollers, the inclined plate being fixedly connected to the inner wall of the outer shell, a sealing plate being provided on the side of the outer shell with an opening, a through groove being provided through the wall of the sealing plate, the inclined plate extending out of the outer shell through the through groove, a feed inlet being fixedly connected to the top of the outer shell, a vibrating motor being installed at the bottom of the outer shell, and support feet being provided at the four corners of the bottom of the outer shell.

[0006] Preferably, both ends of the inclined plate are fixedly connected to support frames, and the support frames are fixedly connected to the inner wall of the outer shell.

[0007] Preferably, a pad is fixedly connected to the bottom of the support foot.

[0008] Preferably, the four support legs are fixedly connected with reinforcing ribs.

[0009] Preferably, a spring is connected to the top of the support foot, and the other end of the spring is connected to the bottom of the outer casing.

[0010] Compared with the prior art, the beneficial effects of this utility model are: the grain vibrating cleaning screen of this utility model has a simple structure and is easy to use. The servo motor set on the outer shell can drive the drive shaft to rotate, and the transmission roller drives the transmission belt to transport the grain. During the transport process, the vibration of the vibrating motor can cause the impurities and dust inside the grain to fall onto the inclined plate along the screen holes on the transmission belt and be discharged along the inclined plate. The screened grain will be transported to the end by the transmission belt and discharged. It can continuously vibrate and clean the grain, which can effectively improve the efficiency of vibration cleaning. Attached Figure Description

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] Please see Figures 1-3This utility model provides a technical solution: a grain vibrating cleaning screen, including an outer shell 1. A servo motor 2 is mounted on the outer wall of one end of the outer shell 1 via a fixed frame. The output end of the servo motor 2 is fixedly connected to a drive shaft 3 via a coupling. The other end of the drive shaft 3 movably passes through the outer shell 1. A driven shaft 4 is rotatably inserted into the inner wall of the outer shell 1 away from the drive shaft 3. Transmission rollers 5 are fixedly sleeved on the shaft walls of both the driven shaft 4 and the drive shaft 3. The two transmission rollers 5 are connected by a transmission belt 6. Next, a number of screen holes 7 are evenly spaced through the outer wall of the transmission belt 6. An inclined plate 8 is provided between the two transmission rollers 5. The inclined plate 8 is fixedly connected to the inner wall of the outer shell 1. A sealing plate 10 is provided on the side of the outer shell 1 with an opening. A through groove 11 is provided through the plate wall of the sealing plate 10. The inclined plate 8 extends out of the outer shell 1 through the through groove 11. A feed inlet 12 is fixedly connected to the top of the outer shell 1. A vibration motor 13 is installed at the bottom of the outer shell 1. Support feet 14 are provided at the four corners of the bottom of the outer shell 1.

[0017] Both ends of the inclined plate 8 are fixedly connected to support frames 9. The support frames 9 are fixedly connected to the inner wall of the outer shell 1. The support frames 9 not only make the inclined plate 8 more stable after installation, but also effectively prevent impurities on the inclined plate 8 from falling onto the transmission belt 6.

[0018] A pad 15 is fixedly connected to the bottom of the support foot 14. The diameter of the pad 15 is larger than the diameter of the support foot 14. The pad 15 makes the support foot 14 more stable when placed on the ground.

[0019] The four support legs 14 are fixedly connected by reinforcing ribs 16, which makes the support legs 14 more stable.

[0020] A spring 17 is connected to the top of the support foot 14, and the other end of the spring 17 is connected to the bottom of the outer shell 1. The spring 17 can effectively prevent the vibration of the outer shell 1 from being transmitted to the support foot 14, thus preventing the device from being unstable.

[0021] Specifically, when using this utility model, the vibration motor 13 and the servo motor 2 are started. When the vibration motor 13 is started, it can drive the outer shell 1 to vibrate. When the outer shell 1 vibrates, it will drive the transmission belt 6 inside to vibrate synchronously. When the servo motor 2 is started, it can drive the drive shaft 3 to rotate clockwise. When the drive shaft 3 rotates clockwise, it can drive the transmission belt 6 to rotate clockwise, thus conveying the material from the left to the right end opening for discharge.

[0022] Grains are fed into the interior of the outer casing 1 through the feed inlet 12 and fall onto the transmission belt 6. As the transmission belt 6 rotates continuously, the grains will be evenly spread on the transmission belt 6, which can effectively avoid the problem of excessive grains causing the sieve holes 7 to be blocked. As the transmission belt 6 vibrates with the outer casing 1, the impurities and dust inside the grains on the upper surface of the transmission belt 6 will fall along the sieve holes 7 onto the inclined plate 8 and be discharged along the downward-sloping inclined plate 8. After the vibration cleaning is completed, the grains will be discharged from the right end opening driven by the transmission belt 6, so as to facilitate the collection of the cleaned grains.

[0023] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
