The supporting legs 104 are connected to each other via the support leg 3, and the inclination angle (grain selection angle) ψ of the external casing 82 and the grain selection net 94 is adjusted by operating the adjustment bolt 105.

A container 106 for storing small particles is disposed below the small particle outlet 96, and a container 106 for storing small particles is arranged below the small particle outlet 96 and the downflow gutter 97.98.
A container 107 for storing large grains is arranged below the large grain outlet 99 to store the large grains among the fine grains that fall from the outlet 99 and the downflow gutter 100. It looks like this.

The present invention is constructed as described above, and its operation will be explained below.

Unsorted grains such as soybeans put into the hopper 3 are placed in the guide frame 3.
0 onto the first sorting belt 4.

Since the belt 4 is inclined in the respective directions as shown by the inclination angles α and β in FIGS. It moves along the flow resistance plate 31 toward the flow outlet 108 (see FIG. 5) without fitting into the flow resistance plate 31 (see FIG. 5).

Also, what are the so-called waste grains and impurities that are not fine grains? -4 gets caught in the grooves 4a on the surface, is transferred to the terminal end side by the same belt 4, and falls into the main sorting chute 7.

By the way, the fine grains moving toward the outlet 108 along the resistance plate 31 described above may be temporarily trapped in this recess by the rounded serrated surface of the resistor 31, or the fine grains may collide with each other. It reaches the exit 108 while changing direction or rolling as appropriate.

Further, the fine grains are temporarily stored in a stopper (flow regulating plate) 109 provided at the outlet 108, and therefore only the fine grains sorted by the above-mentioned rolling action are collected at the outlet 108.
The grains are sequentially introduced into the gutter 95 of the grain sorting section B via the second chute 6.

Next, the remaining particles of the primary sorting particles that have fallen into the main sorting chute 7, that is, the waste particles, etc., fall to the center of the upper surface of the second sorting belt 5.

Then, secondary sorting is performed here by transporting the upgradient belt 5, and the waste particles and foreign matter are transported by the belt 5 to its terminal end.

Further, the fine grains flow down to the starting end side of the belt 5 against the movement of the belt 5, and fall into the container 12 via the second chute 8.

The waste particles transferred by the belt 5 are sequentially thrown into a container 13 for storing waste from the third chute 9.

On the other hand, the fine grains introduced into the fine grain flow down trough 95 of the grain sorting section B are led into the drum-shaped grain sorting net 94 by the iron fence 95, and then are sorted by the rotating iron net 94. It is something that will be done.

In other words, small grains pass through the mesh of the particle screening screen 94 and enter the container 106 from the outlet 96 and the downflow channels 97 and 98, and large particles pass from the lower end of the particle screening screen 94 into the drum 92 and into the cylinder 7.
After being guided into the container 107, the liquid is sequentially introduced into the container 107 through the outlet 99 and the downflow gutter 100.

In short, small grains and large grains among fine grains from the chute 6 are sorted by a grain sorting net 94 and distributed into two containers 106 and 107.

Incidentally, the unsorted grains discharged from the discharge port 3a of the hopper 3 via the guide frame 30 onto the belt 4 are conveyed in the direction of the arrows in FIGS. leading to.

The fine particles are pushed back by the partition plate 71 and guided toward the flow resistance plate 31, while the waste particles are pushed back by the partition plate 71.
The iron plate 71 is pressed and bent against the elastic force of the first sorting belt 4 and is sequentially transferred to the feed end side of the first sorting belt 4.

In this way, from the discharge port 3a of the hopper 3 to the guide frame 3
The majority of the fine grains in the unsorted cavities that flowed out onto the belt 4 through the belt 4 roll toward the resistance plate 31 along the slope shown by the angle α in FIG.

Or it is pushed back by the partition plate 71 and the flow resistance plate 31
guided to the side.

In any case, most of the fine grains in the unsorted cavity roll toward the outlet 108, but a very small number of fine grains roll further in the direction of the arrows in FIGS. 4 and 5 due to the drive of the belt 4. In some cases, the fine grains are transported and reach the fine grain return plate 77.

The fine grains that have reached the fine grain return plate 77 are pushed back by the elasticity of the iron plate 77, and then roll toward the outlet 108 shown in FIG.
It is possible to improve the sorting effect by preventing the fine grains in the unsorted cavity discharged from the discharge port 3a through the guide frame 30 onto the belt 4 from moving to the feed end of the belt 4. be.

In addition, a waste particle passing space G is formed between the lower end of the return plate 77 and the surface of the belt 4, and a notch 77a is formed in the iron plate 77, so that the waste particles transferred by the belt 4 are formed. The waste grains are smoothly transported toward the end of the transport without any obstruction to the passage of the waste particles.

Further, a fine grain return plate 77 is provided using the set bolt 72 as a fulcrum.
When the fine grains are fanned and fixed at the imaginary line position in FIG. 9, the return position of the fine grains can be set slightly to the feed start end side, and the fine grains can be quickly rolled toward the outlet 108 side.

Furthermore, by sliding the plate 74 and the return plate 77 in the direction of the side plate 15 along the elongated hole 74a, the return width of fine grains can be increased. By sliding the return plate 77 upward, the debris passage space G can be made wider, and the passage space G can be set according to the grain size.

As is clear from the above embodiments, the present invention is such that the sorting belts such as the first sorting belt 4, which is an endless belt, are tilted in the vertical direction with a feeding angle, and are also tilted in the horizontal direction with a flow angle. The sorting belt 4 is mounted on a shaft.
In a pulse sorting machine, the hopper 3 is moved from the bottom to the top, and the drop opening of the hopper 3 faces one corner of the lower, elevated side of the sorting belt 4. A fine grain return plate 77 is provided on the higher side of the feed slope with respect to the drop opening of the hopper 3, and the fine grains in the grains to be sorted flowing out from the hopper 3 to the sorting belt 4 move to the upper part of the sorting belt 4. The fine grain return plate 77
Even if there is a group of legumes that are grouped together and are subject to mutual interference, the fine grain return plate 7
By being diffused and separated individually in step 7, all grains to be sorted can be separated and sorted into fine grains and waste grains, and unlike conventional grains, fine grains are mixed with waste grains and are separated in the waste grain removal direction. It is possible to eliminate the fear of the particles flowing down, and the sorting performance can be greatly improved. Therefore, even if the area of the sorting belt 4 is made small, sufficient sorting can be performed, which is a remarkable effect.
