A food screening system

technical field

The utility model belongs to the technical field of grain processing equipment, in particular to a grain screening system.

Background technique

The grain coming out of the harvester often contains dust, wheat ears, wheat bran, shriveled particles, etc., so that the grain cannot be directly stored and used. Therefore, it is necessary to screen the harvested grains to remove dust, wheat ears, wheat bran, shriveled particles, etc.

In order to remove dust, wheat ears, wheat bran, shriveled particles, etc., a grain screening device is used. However, the existing grain screening device is relatively simple, often just a simple filter screen, which makes its screening effect poor. In addition, the degree of automation in screening is low, and the labor intensity of workers is high.

In view of the above-mentioned technical defects of the prior art, it is urgent to develop a novel grain screening system.

The purpose of the utility model is to overcome the shortcomings in the prior art and provide a grain screening system, which has good screening effect, simple structure and high efficiency.

In order to achieve the above object, the utility model provides the following technical solutions: a grain screening system, which includes a grain feeding port, characterized in that the grain feeding port is connected with the first hoist to lift the incoming grain to the sieve The side of the first elevator is provided with a blower to blow away the dust in the grain, and the screen is used to screen out the wheat bran and wheat ears in the grain and make the screened wheat bran and wheat ears float from the floating The grain screened by the screen enters the grain filter located below the screen, the full grain grain screened by the grain screen enters the granary, and the dry grain grain is discharged through the waste grain outlet. , the granary is connected with the second hoist to lift the grain in the granary to the high-rise granary, and a detector for detecting whether the grain is separated is arranged in the high-rise granary, and if the separation is clean, the grain in the high-rise granary It can be directly loaded into the vehicle and transported away. If the separation is not clean, the grain in the high-rise granary will be sent back to the grain feeding port through the conveyor belt for secondary screening and separation.

Wherein, the grain screening system further includes a vibrator connected with the screen.

Compared with the existing grain screening device, the grain screening system of the utility model has the following beneficial technical effects:

1. It can remove dust, wheat ears, wheat bran and shriveled particles in the grain, so the screening effect is good.

2. It can carry out secondary screening and separation of grain to ensure the effect of screening and separation.

3. It has a high degree of automation and low labor intensity.

4. Its structure is simple and easy to use.

detailed description

The utility model will be further described below in conjunction with the accompanying drawings and examples, and the contents of the examples are not intended to limit the scope of protection of the utility model.

Fig. 1 shows the schematic diagram of the composition of the grain screening system of the present invention. As shown in Figure 1 , the grain screening system of the present invention includes a grain feeding port 1 . The grain that needs to be screened and separated enters the grain screening system through the grain feed port 1, so as to realize the screening and separation of the grain.

The grain feeding port 1 is connected with the first hoist 2 to lift the incoming grain to the screen cloth 3 . That is, the first hoist 2 can lift the grain entering from the grain feeding port 2 to the screen 3 located at a high place. Wherein, a blower 4 is provided on the side of the first hoist 2 . In this way, during the process of lifting the grain by the first hoist 2, the dust and the like in the grain can be blown away by the wind blown by the blower 4, thereby realizing the removal of the dust and the like.

The grains entering the sieve 3 are screened and separated by the sieve 3 . Wherein, the grain screened by the sieve 3 enters the grain screener 6 located below the sieve 3 from the mesh of the sieve 3, and the wheat bran and ears of wheat screened out are located on the sieve 3 , and the screened wheat bran and ears are discharged from the flotation outlet. In this way, the removal of wheat bran and wheat ears in the grain can be realized.

In the present invention, preferably, the screen 3 is connected with a vibrator 5 . In this way, the vibration of the vibrator 5 can drive the vibration of the screen 3 , which is more conducive to the separation of grains from wheat bran, ears of wheat, etc., and improves the working efficiency of screening.

Described grain filter 6 is used for realizing the screening of grain, and grain is divided into full grain and dry grain. Wherein, the full-grain grain screened out by the grain filter 6 enters the granary 7, and the dry grain grain is discharged through the waste grain outlet. Like this, through described grain screener 6, can remove the dry grain of particle, further improve the quality of the grain after screening.

The granary 7 is connected with the second elevator 8 to lift the grain in the granary 7 to the high-rise granary 9 . That is, the second hoist 8 can lift the grain in the granary 7 to the high granary 9 located at a high place.

The high-rise granary 9 is provided with a detector for detecting whether the grain is separated cleanly. Through the detector, it can be detected whether the grain entering the high-rise granary 9 is separated cleanly. For example, whether the amount of dust meets the requirements, whether the amount of ears of wheat and bran meets the requirements, and whether the amount of dry grain grains meets the requirements.

In addition, the outlet of the high-rise granary 9 can be directly connected to the vehicle 10 on the one hand, and can be connected to the grain feeding port 1 through the conveyor belt 11 on the other hand. If the detector detects that the grain entering the high-rise granary 9 has been separated, the grain in the high-rise granary 9 can be directly loaded into the vehicle 10 and transported away. If the detector detects that the grain entering the high-rise granary 9 has not been separated, the grain in the high-rise granary 9 is returned to the grain feed port 1 through the conveyor belt 11, thereby performing a secondary process. Screen and separate until the requirements are met.

The grain screening system of the utility model can remove dust, wheat ears, wheat bran and shriveled particles in the grain, so the screening effect is good. At the same time, it can carry out secondary screening and separation of grain, which ensures the effect of screening and separation. Finally, it has high degree of automation, low labor intensity, simple structure and convenient use.

The above-mentioned embodiments of the present utility model are only examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. For those of ordinary skill in the art, on the basis of the above description, other changes or changes in different forms can also be made. All the implementation manners cannot be exhaustively listed here. All obvious changes or variations derived from the technical solutions of the utility model are still within the scope of protection of the utility model.
