Background

Grain refers to the general term of various plant seeds in cooked food, and can also be generally called as "grain", and grain crops contain rich nutrient substances, mainly including protein, vitamins, dietary fibers, fat and the like, and in the early production and processing of the grain, the impurity doped in the grain needs to be screened and separated. At present, generally adopt the mode of selection by winnowing to be to separating grain and impurity, but current grain selection by winnowing equipment structure often is more complicated, and screens thoroughly, especially then can not effectually reject to density, weight be greater than the debris of grain itself, still needs the manual work to carry out the secondary screening, is difficult to guarantee the cleanliness factor of grain, is unfavorable for improving the machining efficiency of grain moreover. Therefore, a grain impurity separation device with good separation efficiency and good separation effect needs to be designed.

Detailed Description

The following description will further describe embodiments of the present invention with reference to the accompanying drawings and examples. The following examples are only for illustrating the technical solutions of the present invention more clearly, and the protection scope of the present invention is not limited thereby.

The utility model discloses the technical scheme who specifically implements is:

as shown in fig. 1, 2 and 3, a grain impurity separating device comprises a base 1, a first separating mechanism, a second separating mechanism and a grain output mechanism;

the first separation mechanism comprises a material guide channel 2, the material guide channel 2 is mounted on a base 1 through a first support 3, the material guide channel 2 is obliquely arranged, the top of the high end of the material guide channel 2 is connected with a material feeding hopper 4, the low end of the material guide channel 2 is provided with a material outlet 5, the bottom plate of the material guide channel 2 is a small impurity sieve plate 6, and first sieve pores 7 are uniformly distributed on the small impurity sieve plate 6;

the second separation mechanism comprises a screening box 8, the screening box 8 is mounted on the base 1 through a second support 9, the screening box 8 is located below the discharge port 5 of the material guide channel 2, the bottom plate of the screening box 8 is a large impurity screening plate 10, and second screening holes 11 are uniformly distributed on the large impurity screening plate 10;

the grain output mechanism comprises a conveyor belt 12, the conveyor belt 12 is installed on the base 1 through a conveying frame 13, and the starting end of the conveyor belt 12 is located below the screening box 8. Through the above technical scheme, when using the utility model discloses a grain impurity separation equipment, pour grain into guide channel 2 from magazine 4, the grain that gets into guide channel 2 will be along the downward landing of little impurity sieve 6, little particle impurity in this in-process grain will drop through first sieve mesh 7, thereby reject little particle impurity in the grain, and large granule impurity in grain and the grain will fall to sieve magazine 8 through discharge gate 5 in, large granule impurity in the grain can't pass through second sieve mesh 11, consequently, large granule impurity will be held back in sieve magazine 8, grain then can pass through second sieve mesh 11 and fall to conveyer belt 12 on, carry clean grain to appointed place by conveyer belt 12.

Further, the aperture diameter of the first sieve hole 7 is smaller than that of the second sieve hole 11.

Further, a small impurity guide groove 14 is arranged below the material guide channel 2, the small impurity guide groove 14 is installed on the base 1 through a third support 15, and the small impurity guide groove 14 is obliquely arranged. By adopting the above-described configuration, the small particle impurities dropped from the guide passage 2 are received by the small impurity lead-out chute 14, and the received small particle impurities are led to a specified place by the small impurity lead-out chute 14.

Further, the guide passage 2 and the small impurity lead-out chute 14 are inclined in opposite directions.
