Combined-type buckwheat shelling machine

Abstract

The invention discloses a combined-type buckwheat shelling machine, which mainly comprises a feed hopper, a milling shelling chamber, a kneading shelling chamber, an air duct 23, an impact shelling chamber and an air duct 29 which are arranged from top to bottom in sequence; a rotating disk and a fixed disk are correspondingly arranged in the milling shelling chamber; a discharge hole 16 is formed in the bottom part of the milling shelling chamber, and the top part of the milling shelling chamber is provided with a milling pan clearance adjustment valve; the kneading shelling chamber is connected below the discharge hole of the milling shelling chamber; two rubber rollers which are different in rotating speed and opposite in rotating direction are correspondingly arranged in the kneading shelling chamber; a discharge hole 19 is formed in the bottom part of the kneading shelling chamber, and the side face of the kneading shelling chamber is provided with a rubber roller clearance adjustment valve; the air duct 23 is connected with the kneading shelling chamber, and the air duct 23 is connected with a fan 24, a feeding hole and a hull dust outlet; the feeding hole of the air duct 23 is connected with the impact shelling chamber; a centrifugal impeller is arranged in the impact shelling chamber; a discharge hole 28 is formed in the bottom part of the impact shelling chamber; the air duct 29 is connected below the discharge hole of the impact shelling chamber; the air duct 29 is connected with a fan 30, a buckwheat rice outlet and the hull dust outlet. According to the combined-type buckwheat shelling machine disclosed by the invention, the buckwheat rice breakage rate of the buckwheat shelling process can be reduced, and the shelling work efficiency and the purity of buckwheat rice are increased.

Description

technical field [0001] The invention relates to an agricultural processing machine, more specifically, relates to a compound buckwheat hulling machine. Background technique [0002] The buckwheat shell and kernel are closely combined, the shell is tough, and the kernel is brittle and fragile. Generally, only a single force action such as grinding, rubbing or impact is used for shelling. Due to the large force once, the shell is torn and broken. While being separated from the kernel, the kernel is also easily broken, so buckwheat has a high breakage rate. Secondly, buckwheat is in the shape of a triangular pyramid. When dehulling is carried out by a single force action such as grinding, rubbing or impacting, the shell is torn and separated from the kernel due to the small force area and fewer force points. The effect is poor, and the shelling work efficiency is low. On the other hand, the general buckwheat hulling machine adopts one wind selection to remove the torn and sep...

Problems solved by technology

[0002] The buckwheat shell and kernel are closely combined, the shell is tough, and the kernel is brittle and fragile. Generally, only a single force action such as grinding, kneading or impact is used for shelling. Due to the large force once, the shell is torn and When separated from the kernel, the kernel is also easily broken, so the broken rate of buckwheat rice is relatively high

Secondly, buckwheat is in the shape of a triangular pyramid. When shelling is performed by a single force action such as grinding, rubbing or impacting, the shell is torn and separated from the kernel due to the small force area and fewer force points. The effect is poor, and the shelling work efficiency is low

On the other hand, the general buckwheat hulling machine uses one winnowing to remove the torn and separated shells and dust, the effect of removing impurities and dust is poor, and the clarity of buckwheat rice is low
