Description

DETAILED DESCRIPTION OF THE INVENTION As shown in Japanese Patent Publication No. 33-7659, a transverse splitter in which rocking protrusions are aligned parallel or oblique to the direction of flow of grains in which brown rice and paddy are mixed is used in the flow direction of grains. It swings back and forth horizontally or in a near-horizontal arc shape that includes an elevation angle of 0°, first sinking the heavy brown rice, and then using the rocking projections to push the settled brown rice to one side of the horizontal splitting plate. Then, the piled up brown rice is smashed against one side wall, and the upper layer of brown rice is pushed down to the opposite side of the horizontal splitter, causing it to sink to the bottom of the paddy. There are some that are placed on one side and then split horizontally on the opposite side.

However, this horizontal splitter not only applies shock to the grains, but also causes the brown rice that has been shaken to one side to circulate back to the other side, resulting in poor lateral efficiency, and the thickness of the sunken brown rice layer is reduced. If the height of the protrusions does not match, that is, if the thickness of the brown rice layer is low, the protrusions will push not only the brown rice but also the paddy layer above it to one side, and if the thickness of the brown rice layer is high, the protrusions will The upper layer of brown rice cannot be moved to one side and remains together with the paddy, and stable horizontal splitting cannot be expected.

In addition, the inclination angle with respect to the flow direction of the grains and the elevation angle with respect to the bottom surface of the rocking protrusions to be aligned must be set appropriately according to the quality of the grains and the mixing state. Depending on the situation, it is necessary to prepare a horizontal splitting board with various rocking protrusions in advance.

The object of the present invention is to eliminate such drawbacks, to efficiently cross-split any mixed grains using one type of horizontal splitting board, and to make the structure of the horizontal splitting board extremely simple.

To explain one embodiment of the present invention shown in the drawings, reference numeral 1 denotes a non-porous horizontal splitting plate that compresses to form a large number of uneven surfaces.

A non-perforated horizontal splitting board 1 is mounted on a supporting frame 2 so as to be inclined in the direction in which grains flow down, that is, in the lateral direction.

A supply tank 3 is visible on the high side, and discharge ports 4 and 5 for brown rice and paddy are provided on the left and right sides of the end plate on the low side, and a discharge port 6 for mixed grains of paddy and brown rice is provided in the center.

Reference numeral 7 denotes an adjustment plate for adjusting the position and size of the outlet 6, and an outlet that overlaps with the outlet 6 is bored.

Reference numeral 8 denotes a support leg that is attached to the support frame 2 so as to be swingable obliquely in a direction perpendicular to the grain flow direction, that is, in the vertical direction. move.

10.11 are the right and left side plates of the horizontal splitting board 1.

When mixed grains of paddy and brown rice are supplied to the horizontal dividing plate 1 which has a discharge port high at the rear in the lateral direction and has a low slope at the front facing into the supply tank 3 of the present invention, the mixed grains of paddy and brown rice flow down in the horizontal direction toward the front. If the upper end of the support leg 8 is tilted to the left as in the embodiment shown in FIG. It swings vertically around the bottom end of 8, high to the right and low to the left.

When the horizontal splitting board 1 swings, each supporting leg 8 swings vertically diagonally up and down with its upper end using its lower end as a fulcrum, but strictly speaking, the locus of the swinging of the upper end is a circular arc.

However, since the amplitude is short, it can actually be regarded as a diagonal straight line.

Since the horizontal splitting plate 1 has many uneven surfaces to increase the frictional resistance against the grains, the brown rice sinking to the lower layer while flowing forward gets caught on the uneven surface of the horizontal splitting plate 1 and slips. Then, when the horizontal splitter descends to the left, the upper layer of brown rice remains on the right side and falls to the left.

As this action is repeated, the heavier brown rice in the lower layer gradually shifts to the right side plate 10 on the side that swings higher, and the lighter paddy in the upper layer moves to the left side plate 11 on the side that swings lower, and a small amount is distributed in the middle. The mixed grains of paddy and brown rice are separated and discharged from the machine through respective discharge ports 4 and 5.6.

Furthermore, when a mixture of whole grains such as whole wheat grains and crushed grains such as broken wheat grains is supplied to the horizontal splitting machine of the present invention, the crushed grains are caught on the uneven surface and are placed on the high right side and completely. Separate the grains to the lower left side.

In this way, according to the present invention, while the mixed grains flow down in the horizontal direction on the non-porous horizontal dividing plate 1, the grains that have sunk to the lower layer are not allowed to slide due to the frictional resistance caused by the uneven surface, but are moved vertically higher to the right side. As the grains are pushed up, they can be reliably transferred to the right side of the horizontal splitting plate without giving any impact to the grains, and the grains floating on the upper layer move to the left as the horizontal splitting plate descends vertically to the left, and the grains in the lower layer are moved to the left. Separation is more rapid, and since the horizontal splitting plate is non-perforated, air is not blown up from the bottom surface even when it is rocked diagonally up and down, so the grains sinking downward do not float up, as shown in the top view of Figure 6. It can be reliably caught on many uneven surfaces and pushed up to the right side, and the grains separated vertically to the left and right will never mix again, so it has an excellent horizontal one-height hit rate. Since the uneven surface of the horizontal splitting board 1 can be easily formed by squeezing with a press, the work is extremely simple and suitable for mass production, and it has the effect that various mixed grains can be horizontally processed with one type of horizontal splitting board.
