Description

DETAILED DESCRIPTION OF THE INVENTION The present invention is an improvement in a bean washing device that washes off mud adhering to the surface of harvested and threshed soybean beans during the threshing process to produce beans with a clean surface. Regarding.

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 beans separated from the capsule, the harvested beans are taken out as dirty grains whose surfaces are contaminated with mud.

The bean cleaning device is used to turn the dirty beans that are taken out into clean fine particles.
As shown in Fig. 1, wet wiping belts a and b, which are wet endless belts, are placed vertically opposite each other at intervals corresponding to the particle size of peas G, and placed on the machine frame f. The wiping belts a and b are driven and rotated with a difference in circumferential speed, and the grains G are supplied from one end of the opposing interval and taken out from the other end. , the mud on the surface of the beans G is removed by wiping belts a and b.
Try wiping it off.

By the way, soybean grain cleaning equipment constructed in this way is equipped with a wet-type endless belt because soybean grains absorb moisture immediately when soaked in water, causing wrinkles to form on the skin and lowering the quality grade. There is a constraint that the contact time with the wiping belt a-b, which is made up of peas, must be extremely short, and under this constraint, it is difficult to efficiently and cleanly wipe away the mud adhering to the entire surface of the bean. There is.

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 a @b to the wiping belt a@b, which causes a problem that efficiency cannot be improved.Also, the repeated supply to the wiping belt aIIb causes a problem that absorbs a lot of moisture and produces wrinkled beans. This was done in order to solve these problems that occur in the conventional bean cleaning device, and it minimizes the contact time of the large σ peas G with the wiping belts a and b, and cleans the peas. From the entire surface of the bean G, while avoiding wrinkles on the epidermis of G,
It is an object of the present invention to provide a highly efficient pea washing device that can cleanly wipe off mud adhering to the dirt with a wiping belt a*b without leaving any residue.

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 peas G with wet wiping belts a and 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 aeb are stretched across the machine frame so as to face each other with an interval corresponding to the grain diameter r of the pea grains G, and the wiping belts aeb are driven and rotated so that their opposing sides move at approximately the same speed and in mutually opposite directions. As a result, the beans G supplied within the opposing intervals are kept rotating on the spot, and the upper wiping belt a is supported as shown in Fig. 3. The rocker frame 10 is connected to the main engine frame 1.
A conveyor C is provided which reciprocates left and right against the wiping belts, and which passes within the opposing interval between the upper and lower wiping belts a and b, and by that other conveyor C, the belt continues to rotate on the spot as described above. When the soybean grains G... are conveyed in a state where they are surrounded by several or several grains at a time, when the supplied soybean bean G... enters the opposing interval between the upper and lower wiping belts a*b, On the spot, it rotates at high speed and rolls left and right with its horizontal axis of rotation, and the entire surface evenly contacts the circumferential surfaces of the upper and lower wiping belts a*b repeatedly in a very short time. The peas G in this state are carried out at the rotating speed of the conveyor C passing within the opposing gap, and the peas G...
By selecting the rotational speed of the peas, it was possible to wipe the entire surface of the peas G evenly and cleanly in an extremely short period of time without wrinkles on the surface of the peas G.

For this reason, in the present invention, above the lower wiping belt mounted on the machine frame, an upper wiping belt mounted on a swinging frame supported so as to be movable from side to side with respect to the machine frame.
The lower side of the wiping belt and the upper side of the lower wiping belt are opposed to each other with an interval corresponding to the particle size of the bean, and within the opposing interval, the upper and lower thicknesses are larger than the particle size of the bean. A conveyor that surrounds and transports the peas by a thinned transport member is installed so that the transport member passes from one end of the opposing gap to the other end, and the upper and lower wiping belts are connected to each other. The present invention proposes a bean cleaning device in which the opposite sides of the oscillating machine are driven to rotate in opposite directions to cause the oscillating frame to reciprocate from side to side.

Next, embodiments will be described in detail with reference to the drawings. Note that the same reference numerals in the drawings as in the previous means are used for components having the same effect.
