Description

Technical Field

[0001] The utility model relates to the field of grain raw material screening machines, in particular to a vibration type grain raw material screening machine. Background Art

[0002] The five grains refer to five kinds of cereals. There are many different interpretations of the "five grains" in ancient times, and the two most important ones are: one refers to rice, millet, sorghum, wheat, and beans; the other refers to hemp, millet, sorghum, wheat, and beans. The difference between the two is that the former has rice but no hemp, while the latter has hemp but no rice. The economic and cultural center of ancient times was in the Yellow River Basin, and the main rice producing areas were in the south, while rice planting in the north was limited, so rice was not originally included in the "five grains".

[0003] At present, when grains are produced and collected, they are mostly directly packed into bags. In this way, the collected grains are not screened, which easily makes the collected grains uneven in size, thus affecting the quality of the grains and affecting their sales. Utility Model Content

[0004] In order to solve the above problems, the purpose of the utility model is to provide a vibrating grain raw material screening machine to solve the problems raised in the above background technology.

[0005] To achieve the above-mentioned purpose, the utility model proposes a vibrating grain raw material screening machine, comprising a screening machine body, a feed hopper is fixedly installed on the top of the screening machine body, and a supporting leg is fixedly installed on the bottom of the screening machine body;

[0006] A screening mechanism is provided inside the screening machine body, and the screening mechanism includes a feed chute plate, a sieve plate, a fixed shaft, a fine discharge chute plate, a first through slot and a second through slot. The first through slot and the second through slot are respectively provided on one side and the bottom of the screening machine body. Fixed shafts are fixedly installed on the inner walls of both sides of the screening machine body, and the ends of the two fixed shafts close to each other are rotatably connected with a feed chute plate that penetrates through and extends to the outside of the first through slot. A sieve plate is fixedly installed on one side of the inner wall of the feed chute plate, and a fine discharge chute plate that penetrates through and extends to the outside of the second through slot is fixedly installed on the bottom of the feed chute plate. A rubber pad connected with the first through slot is fixedly installed on the bottom of the feed chute plate.

[0007] In one example, arc-shaped grooves are provided on the inner walls on both sides of the screening machine body, and the inner walls of the two arc-shaped grooves are slidably connected with slide plates fixed to the unloading chute plate.

[0008] In one example, a card slot is formed at the bottom of the two slides.

[0009] In one example, a motor is fixedly mounted on one side of the screening machine body, a rotating shaft is fixedly mounted on the output shaft of the motor, and the rotating shaft penetrates and extends into the screening machine body.

[0010] In one example, the outer ring of the rotating shaft located in the screening machine body is fixedly mounted with two top plates, and the two top plates match the card slots.

[0011] In one example, two auxiliary support rods are fixedly mounted on the top of the screening machine body, and the tops of the two auxiliary support rods are fixedly connected to the feed hopper.

[0012] The vibrating grain raw material screening machine proposed by the utility model can bring the following beneficial effects:

[0013] 1. This vibrating grain raw material screening machine, by sliding the slide plate in the arc groove, drives the material discharge chute plate to swing around the fixed axis, and screens the grains on the sieve plate, preventing the grains from being directly discharged from the material discharge chute plate, so that the grains can be screened and convenient for classification and collection.

[0014] 2. This kind of vibrating grain raw material screening machine can drive the rubber pad to swing when the material discharge chute plate swings around the fixed axis, and collides with the first through groove, so as to buffer the material discharge chute plate and prevent it from colliding with the first through groove during the swinging motion, thereby achieving better buffering and protection effect when the material discharge chute plate swings.
