Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an improvement in a bean washing device for washing off mud adhering to the surface of harvested and threshed soybean grains during the threshing process to obtain bean grains with a clean surface. .

When soybean shell culms are harvested with a harvester and processed for shedding, the soybean pods are attached near the base of the stem culm, so the soybean shell culms are harvested from near the root to be processed for shedding. A large amount of mud will be put into the room together with the culms. Then, as this mud adheres to the surface of the soybean grains that are separated from the capsule, the harvested soybean grains are taken out as dirty grains with muddy soil on the surface. It is for finishing the soybean grains, which are taken out in the form of dirty grains, into clean fine grains, and is usually as shown in Fig. 1.

Wet wiping belts a and b, which are wet endless belts, are mounted on the machine frame f so as to face each other vertically with an interval approximately corresponding to the particle size of a soybean bean G, and these wiping belts aIIb are , are driven and rotated with a difference in circumferential speed, and the beans G are supplied from one end of the opposing interval and taken out from the other end, and during this time, the mud on the surface of the beans G is wiped away. However, in a bean washing device configured in this way, the soybean bean immediately absorbs moisture when soaked in water, causing wrinkles to form on the epidermis, resulting in a problem with the quality grade. Therefore, there is a constraint that the contact time with the wiping belts a and b, which are wet endless belts, must be extremely short, and under this constraint, it is difficult to wipe the surface of the beans cleanly.

When soybean peas G are soaked in water, it usually takes about - minutes for wrinkles to appear on the epidermis, and wrinkles begin to appear after - minutes. Therefore, in the above-described bean cleaning device A, the supplied bean particles pass between the wiping belts a and b at least three times.
It is designed to pass through in about 0 seconds, but in that case, the supplied beans will be taken out with mud attached to a part of the surface, so the wiping belt will be repeatedly removed. It becomes necessary to apply the wiping belts a and b, which causes a problem that efficiency cannot be improved, and the repeated supply to the wiping belts a and b causes the problem of absorbing a lot of moisture and producing wrinkled peas. The present invention has been made in order to solve the problems that have arisen in the conventional bean washing apparatus, and it is possible to reduce the contact time of the soybean bean G with the wiping belt a-b while minimizing the contact time of the soybean bean G with the wiping belt a-b. The purpose of this invention is to provide a new means for wiping off mud adhering to the entire surface of a bean G with a wiping belt a.

Therefore, the present invention has been completed based on the knowledge obtained through various studies for the above-mentioned purpose. That is, when wiping the surface of a bean G... with wet wiping belts a@b provided vertically facing each other, as shown in FIG. 2, the upper wiping belt a and the lower wiping belt b are
The wiping belts a11b are stretched across the machine frame so as to face each other with an interval corresponding to the grain size r of the pea grains G.
are driven and rotated so that their opposing sides move in opposite directions at approximately the same speed, so that the peas G... supplied within the opposing intervals continue to rotate on the spot. , the soybean grains G... are conveyed from one end to the other within the opposing interval by a conveyor C, which is separately provided so as to pass through the opposing interval between the upper and lower wiping belts a and b. As a result, each of the supplied peas G... rotates within the interval with a circumferential speed corresponding to the rotating speed of the wiping belt a@b, so it rotates many times in an extremely short time on the order of seconds. Wiping belt a1 with even surface
1b, and in that state, the conveyor C carries out the peas G at its rotation speed, and the desired rotation speed is selected by the conveyor C. It was completed by obtaining the result that the surface of the bean G... could be wiped cleanly in a short period of time.For this reason, in the present invention, the upper wiping belt and the lower wiping belt are connected to each other according to the particle size of the bean. The wiping belts are mounted on the machine frame so that they face each other vertically with an interval corresponding to A bean washing device is proposed in which a conveyor that surrounds and transfers bean G using a conveying member made thinner than the diameter of the bean is installed so as to pass from one end of the opposing gap to the other end. It is something.
