Description

Bucket conveyor

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a bucket conveyor for transferring a sample to a subsequent process when measuring the milling yield of rice, and more particularly to a bucket conveyor suitable for use in transferring brown rice samples to a rice milling process.

Rice is one of the main food resources, and methods for producing high quality rice have been sought from various angles. For this, quality control of rice is the first priority. The quality of rice depends on growing rice control, climatic condition, threshing and drying method after harvesting. If these conditions are not suitable, the quality of rice is unsatisfactory, snowy rice, and crayfish. The term 'bad taste' is abundantly generated so that the yield of perfect rice is greatly reduced.

Therefore, in the purchase of rice, it is fair to determine the purchase price according to the degree of rice production compared to rice production by accurately measuring the procurement yield of rice to be purchased, ie, the amount of perfect and bad rice. It is a preferred way to.

However, it is common to judge the quality of rice to be inspected manually by the visual inspection of the inspector at the time of rice purchase.In addition, the determination of low-grade rice having a large amount of bad taste cannot be judged objectively and accurately. , Grade 3,… Because of the fact that it is not possible to make a differential purchase according to the grade, the person who produced high-quality rice with a relatively high yield of rice is damaged.

In addition, it is possible to determine rice milling yield step by step by using several manually operated machinery when purchasing rice. However, in this case, it takes much time and effort, and it is still subject to the subjectivity of the inspector. There is concern that it will occur.

On the other hand, government agencies collect rice samples from all over the country every year, and measure and notify the yield of rice produced by region.In this case, large scale rice plant facilities are used, which consumes a lot of rice samples and requires much time and effort. Will be. Moreover, since this is a sampling of a part of the area and is measured, it cannot be used as a quality criterion for purchasing rice produced by individual farmers.

Accordingly, the present applicant has filed several test unit devices that can automatically determine the yield of each cutting step at the time of purchase of rice, and re-threats and selects only by injecting rice of threshed quantity using them once. After the rice flour was produced, the applicant applied the so-called 'rice grade automatic determiner' (Application No. 96-33580), which can automatically and objectively and accurately determine the quality of rice by separating and weighing perfect brown rice and seolhyun rice. In addition, the 'whiteness automatic determination machine' which can automatically determine the whiteness rate by measuring the weight of each after processing the brown rice into white rice and separating it with perfect rice and loaves is applied as the same as the present invention.

However, since the rice grade automatic determiner and the automatic rate determiner are separated from each other, there is a troublesome problem of manually inputting the brown rice obtained from the rice grade automatic determiner and putting it into the automatic rate determiner. As a result, it is difficult to guarantee the transparency of the brown rice obtained from the first rice sample, such as the possibility of spilling brown rice during the transfer. .

The present invention has been made in view of the above-described conventional problems, and an object thereof is to provide a bucket conveyor capable of automatically transferring brown rice obtained from a rice sample discharged from a rice grade automatic determiner to a rice polisher of a white scale automatic determiner.

It is another object of the present invention to provide a bucket conveyor capable of serving as a net discharge chute function of an automatic weighing rate automatic determiner which collects net rice milled from brown rice and feeds it into a bucket for transfer to a subsequent process.
