As a further improvement, the cleaning bucket is connected to the water pump through the lower water pipe and the upper water pipe respectively, and a filter is fixed on the lower water pipe.

As a further improvement, a sprayer is provided above the notch of the U-shaped frame, and the sprayer is fixed on the filter tank.

As a further improvement, the stirring device is a propeller.

As a further improvement, the mesh number of the filter net is 1.

As a further improvement, the meshes of the annular filter plate, the first filter plate and the second filter plate are 150.

The utility model has a simple structure. The dust and fine sand are preliminarily separated by the primary separation device, and then washed with water, which increases the cleaning efficiency and saves the water consumption. The water is circulated through the water pump and the filter device, further saving the water consumption.

detailed description

The technical solution of the utility model will be described in detail below through specific embodiments and in conjunction with the accompanying drawings.

A kind of wheat cleaning equipment as shown in Figure 1-5, comprises filter tank 1, and the bottom of filter tank 1 is fixed with filter screen 2; Below filter tank 1, several fans 3 are arranged, and fan 3 is fixed on the U-shaped frame 4; A funnel 5 is fixed below the U-shaped frame 4, and a first filter plate 6 arranged obliquely is arranged below the funnel 5, and the first filter plate 6 is connected to the feed port 8 of the cleaning bucket 7; the top of the cleaning bucket 7 is provided with a water inlet 9 , the bottom of the cleaning bucket 7 shrinks inwardly to form a truncated conical truncated cone 10, the middle part of the truncated cone 10 is fixed with an annular filter plate 11, and the bottom of the truncated cone 10 is provided with a desilting valve 12; the truncated cone 10 Stirring devices 13 are respectively arranged on both sides of the tank, and the stirring device 13 is above the annular filter plate 11; a screw feeder 14 is arranged in the cleaning bucket 7, and the discharge end of the screw feeder 14 is connected with a second filter plate 15 which is inclined to be arranged. The second filter plate 15 is connected to the discharge port 16; the mesh number of the filter screen 2 is ≤5; the mesh numbers of the first filter plate 6 and the second filter plate 15 are ≥100.

The utility model filters out larger impurities such as stalks in the wheat through the filter screen 2, and the fan 3 blows away most of the light dust and wheat husks in the wheat granules during the falling process of the wheat granules; the wheat granules fall to the first After the filter plate 6, heavier impurities such as sand fall through the filter holes on the first filter plate 6 and separate from the wheat; then the wheat rolls into the cleaning bucket 7 along the first filter plate 6 for cleaning. The two stirring devices 13 form two vortexes of relative flow, which increases the cleaning effect of the wheat. The screw feeder 14 transports the cleaned wheat to the top, and discharges through the second filter plate 15 . The water in the wheat falls through the filter holes of the second filter plate 15, which not only recycles the water, but also facilitates subsequent drying and dehydration. The arrangement of the truncated cone portion 10 and the annular filter plate 11 makes the soil in the water gradually settle below the annular filter plate 11, which increases the cleaning effect of wheat and reduces the frequency of water changes. When there is too much silt, open the desilting valve 12 to remove silt.

The cleaning bucket 7 communicates with the water pump 19 through the lower water pipe 17 and the upper water pipe 18 respectively, and a filter 20 is fixed on the lower water pipe 17 . This allows the water source to be reused by filtering out impurities in the water.

The stirring device 13 is a propeller.

A sprayer 21 is arranged above the gap of the U-shaped frame 4 , and the sprayer 21 is fixed on the filter tank 1 . The dust that sticks wet blower 3 to blow out by the water vapor sprayed by sprayer 21 like this prevents dust from being too large during work, causing pollution and repeated dust removal.

The stirring device 13 is preferably a propeller.

The practice process finds that when the mesh number of the filter screen 2 is 1, the rate of leakage of wheat grains and the effect of intercepting impurities are better.

The mesh numbers of the annular filter plate 11, the first filter plate 6 and the second filter plate 15 are preferably 150, which is convenient for unified manufacturing.

The above is only a specific guiding implementation of the present utility model, but the design concept of the present utility model is not limited thereto, and any insubstantial changes made to the utility model by using this concept should all belong to the infringement of the protection scope of the present utility model the behavior of.
