Description

Technical Field

[0001] The utility model relates to the technical field of grain vibration concentrators, in particular to a low-noise grain vibration concentrator. Background Art

[0002] Grain vibration separator is a mechanical equipment used to select grains. It is mainly composed of vibrator, screen, hopper, motor and other components. The vibrator is used to generate vibration, the screen is used to screen grains, the hopper is used to load grains, and the motor is used to drive the vibrator and screen.

[0003] When using the common vibration separators on the market, the grain to be separated is usually poured into the feed port, and the screen vibrates to separate the grain. During the separation process, grain may get stuck in the holes of the screen, which is not easy to clean. Therefore, a low-noise grain vibration separator is proposed to solve the above problem. Utility Model Content

[0007] Preferably, sound-absorbing cotton is fixedly connected inside the protection frame, and the protection frame is arranged on the outside of the machine body.

[0008] Preferably, a pipe bracket is tightly fitted on the outer side of the other connecting pipe, and the pipe bracket is fixedly connected to the inner side of the protective frame.

[0009] Preferably, a plurality of elastic blocks with arc-shaped protrusions are fixedly connected to one side of the clamping block, and the elastic blocks are tightly fitted with the protrusions of the sliding grooves provided in the top plate of the protection frame.

[0010] Preferably, the sliding plates are arranged in groups of two on the top plate of the protective frame, a handle having a spherical end is fixedly connected to the top of the sliding plate, and a rubber layer is fixedly connected to one side where the two sliding plates are in contact.

[0011] Compared with the prior art, the beneficial effects of the utility model are:

[0012] In the utility model, the machine body, the feed port, the screen, the support plate, the protection frame, the fan, the connecting pipe and the collection box are arranged. When the grain is stuck in the hole of the screen during the screening process, after the screening is completed, the user starts the fan, and the fan sucks the grain on the surface of the screen from the connecting pipe to the collection box, so as to facilitate the cleaning and collection of the grain stuck in the screen hole, thereby facilitating the secondary screening. Since the protection frame is transparent, it is convenient for manual real-time monitoring of the screening and cleaning process. The sound-absorbing cotton arranged in the protection frame can effectively reduce the noise of the machine body during use. The pipe bracket arranged on the outside of one of the connecting pipes makes it difficult for the fan to shake during use. The sliding plate, the limit plate, the slide groove, the sliding bar and the card block are arranged, and the sliding of the sliding plate makes the sliding of the sliding plate not affect the feeding of the machine body. The elastic block arranged at the edge of the card block can effectively fix the sliding plate when it is in the open and closed state. The handle arranged on the top of the sliding plate is convenient for the user to move the sliding plate. The rubber layer arranged on one side of the sliding plate has a buffering effect when it is closed, and protects one side of the sliding plate from being easily damaged when it is closed.
