Description

An adhesive type impurity removing device for cleaning oatmeal

technical field

The invention relates to the field of oat impurity removal devices, in particular to an adhesive type impurity removal device for cleaning oats.

Background technique

Oatmeal is a low-sugar, high-nutrition, high-energy food, rich in dietary fiber, can promote gastrointestinal motility, facilitate defecation, low calorie, low glycemic index, lipid-lowering and hypoglycemic. It is also one of the high-end supplements and is indispensable in poor areas. of dry food. my country is the largest oat producer, consumer and exporter in the world, and the scale of China's oat consumption market is gradually expanding, which puts forward higher and higher requirements for oat production capacity. In the prior art, after the oats in the field are harvested, the obtained oat mixture cannot meet the cleanliness requirements for grain storage or oat food processing, and needs to be treated with impurity removal. During grain storage, the oat mixture is generally subjected to mechanical removal of impurities, which has problems such as poor grain cleaning effect and high cost; before oat food processing, the washing method is generally used to remove impurities, resulting in waste of water resources and water pollution, etc. Problems will cause grain loss and reduce impurity removal efficiency. Therefore, the existing oat impurity removal method is not only complicated, but also difficult to effectively separate oat grains and impurities, and the impurity removal rate is low.

SUMMARY OF THE INVENTION

In order to solve the problems that the existing oats are relatively complicated to remove impurities, easily cause the loss of grains, and the removal rate is low, the present invention provides an adhesive type impurity removal device for cleaning oats.

The technical scheme adopted by the present invention to solve the above-mentioned technical problems is as follows: an adhesive type impurity removing device for cleaning oats, comprising a casing, a feeding hopper is installed on the top of the casing, and two pulleys are provided in the casing for Undertake the conveyor belt that drops the material from the bottom end of the feeding hopper. There is a scraper above the conveyor belt. The scraper is located on the side of the feeding hopper along the conveying direction of the conveyor belt, and is in contact with the material through the bottom edge of the scraper. The material is distributed on the conveyor belt to form an equal-thickness layer; the surface of the conveyor belt is pasted with a layer of cotton material, and a plurality of rubber rollers are arranged above the conveyor belt. On one side, there are a plurality of brush rollers under the conveyor belt. The axes of the rubber rollers and the brush rollers are parallel to the axis of the pulley. The outer peripheral surface of the rubber rollers is pressed on the upper surface of the conveyor belt. It cooperates with the cotton material to make the impurities in the material adhere to the upper surface of the conveyor belt, so that the oat grains in the material slide down from one side of the conveyor belt along its conveying direction, and the impurities are transported to the lower surface of the conveyor belt. The cleaning of the lower surface of the conveyor belt when the brush roller rotates makes the impurities fall off from the lower surface of the conveyor belt. The bottom surface of the shell is provided with a trash collection box and a grain collection box. The grain collection box is located on the side of the conveyor belt along its conveying direction. Below the bottom of the casing, there is also a motor for driving the pulley, the rubber roller and the brush roller to rotate synchronously.

Preferably, the lengths of the rubber roller and the brush roller along the axial direction are not less than the width of the conveyor belt.

Preferably, one end of the conveyor belt is located directly below the feed hopper, and the end of the conveyor belt away from the feed hopper is higher than the end of the conveyor belt located directly below the feed hopper, so as to prevent the material from slipping on the conveyor belt along the conveying direction .

Preferably, the number of the rubber rollers and the brush rollers is the same, and the multiple rubber rollers and the multiple brush rollers are respectively arranged at equal intervals along the conveying direction of the conveyor belt.

Preferably, the motor is located under one side of the conveyor belt along its conveying direction, the motor drives a pulley close to it to rotate through a V-shaped belt, and the axle of the pulley is connected to the rubber roller on the side of the motor through two V-shaped belts respectively. It is connected with the axle of the brush roller, and a respective section of V-shaped belt is connected between the axles of two adjacent rubber rollers and the axles of the two brush rollers.

According to the above-mentioned technical scheme, the beneficial effects of the present invention are:

The adhesive type impurity removing device for cleaning oats provided by the invention feeds the oat mixture harvested by the oat combine harvester into the feeding hopper, so that the oat mixture falls to the upper surface of the conveyor belt, and when the oat mixture passes through the scraping material The bottom end of the scraper plate will be spread into a uniform material layer, and the material layer will be squeezed by multiple rubber rollers in turn. Due to the uniform thickness of the material layer, the local accumulation of materials on the conveyor belt can be avoided. In the case of strong extrusion force for some materials and weak extrusion force for some materials, to ensure that all materials are evenly extruded; a layer of cotton material is attached to the surface of the conveyor belt, which is extruded by rubber rollers. Cooperate with cotton material, so that the impurities such as shelled grains, weeds, oat husks and other impurities in the material adhere to the upper surface of the conveyor belt, while the surface of the oat grains is relatively smooth and will not be affected by the conveyor belt with cotton material. Adhesion, when the material is transported to the end of the conveyor belt, the oat grains will slide off the edge of the conveyor belt and fall into the grain collecting box, and the impurities will continue to adhere to the surface of the conveyor belt and be transported To the lower surface of the conveyor belt, there are a plurality of brush rollers under the conveyor belt. By cleaning the lower surface of the conveyor belt when the brush rollers rotate, the impurities fall off from the lower surface of the conveyor belt and fall into the collection box. , the impurity removal treatment of the oat mixture is realized, and the oat grains and impurities are effectively separated.

To sum up, the present invention utilizes the characteristics that impurities in oat are more easily adhered to cotton materials and oat grains are not easily adhered, and the impurities are separated from the oat grains, which can effectively improve the cleanliness of the oat grains and reduce the loss of grains. , improve the impurity removal rate, and provide great convenience for subsequent oat storage and oat product processing. The invention can be realized by the cooperation of the rubber roller and the brush roller, the structure is simple, the manufacturing cost is low, and the invention has high practical value, and overcomes various problems in the existing oat impurity removal.
