Description

A vibrating cleaning screen for grain screening

Technical Field

The utility model relates to the technical field of grain screening, in particular to a vibration cleaning screen for grain screening.

Background Art

During the grain processing process, a lot of sand and gravel particles of different sizes will be mixed in and cannot be separated from the grain, causing great trouble for grain processing.

The grain filtering and processing steps in the prior art are complicated. It is necessary to filter large particles of sand and gravel and other impurities for the first time, and filter small particles of sand and gravel and other impurities for the second time. After the filtration, the sand and gravel and other impurities are scattered and inconvenient to collect and process them, resulting in a large amount of manpower and material resources being wasted in unnecessary links. The existing grain processing does not perform multiple filtrations, and there will be residual sand and gravel and other impurities. The filtering effect is not significant, and the screened grain cannot be discharged quantitatively.

For example, a vibrating cleaning screen for grain screening disclosed in Chinese patent publication number CN218360694U has a first vertical mounting plate and a second vertical mounting plate symmetrically fixedly connected to the upper surface of the bottom plate, a feed hopper, a first vibrating cleaning screen device, and a second vibrating cleaning screen device are sequentially connected to the space between the first vertical mounting plate and the second vertical mounting plate from top to bottom, a cleaning drive mechanism is connected between the first vertical mounting plate and the second vertical mounting plate, the cleaning drive mechanism cooperates with the first vibrating cleaning screen device and the second vibrating cleaning screen device, and the impurities in the grain particles are screened out by driving the vibrator and the electric telescopic rod, thereby realizing the grain selection operation, thereby improving the practicality.

The existing technology has the following problems:

However, the above-mentioned device lacks a corresponding vibration method in the primary screening of grains. Therefore, grains with coarse particles that are the same size as large grains of sand and gravel can easily accumulate on the large-particle screen along with the large grains of sand and gravel, resulting in reduced screening effect and possible waste of grain.
