A container 116 for storing large grains is arranged below the large grain outlet 108 to store the small grains (small diameter grains) among the fine grains falling from the outlet 108 and the downflow gutter 109. It is designed to store large grains (large diameter grains).

Further, a U-shaped guide plate 119 is attached to the fine grain receiving trough 104 using a fixing bolt 117 and a wing nut 118 so as to be vertically adjustable.
It is configured to prevent the fine grains falling from the grains into the gutter 104 of the grain sorting section B from overflowing to the outside of the gutter 104.

As shown in FIGS. 3 to 5 and 7, the above-mentioned waste particle guiding chute 69 has an upper end opening formed on the higher side of the feeding end portion of the first sorting belt 5, and is used for storing waste particles. A lower end opening is formed on the container 13, and the waste grains sorted by the first sorting belt 5 are directly transferred and dropped into the third opening, that is, into the container 13 from the inclined high side of the end of the feed. .

Next, the mounting structure of the fin 86 will be described with reference to FIGS. 3 to 4 and FIGS. 9 to 10.

This fin 86 has an L-shaped cross section and is attached to the inside of the belt cover 85 at an angle as shown in FIG.

In other words, one end of the fin 86 is connected to the cover 85 near the right side plate 71.

In addition, as shown in FIG. 9, a slight gap g is provided between the lower end of the fin 86 and the surface of the belt 6, and only the fine grains among the primary sorted grains that have fallen from the main sorting chute 8 are transferred to the fin. 86 and is configured to be quickly dropped into the second chute 9.

With this configuration, the height h of the second chute 9 (the third
(see figure) is regulated, the particle flow downward angle δ is
As shown in the figure, the angle can be set relatively steeply.

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

The unsorted grains such as soybeans put into the hopper 4 are placed in the guide frame 3.
8 onto the first sorting belt 5.

Since the belt 5 is inclined in the respective directions as shown by the inclination angles α and β in FIGS. 3 and 4, the fine grains (sized grains) fit into the grooves 5a formed on the surface of the belt 5. It moves along the flow resistance plate 40 toward the flow outlet 39 (see FIG. 5) without any movement.

In addition, so-called waste grains and impurities that are not fine grains are caught in the grooves 5a on the surface of the belt 5, and are transported by the belt 5 to its terminal end and fall into the main sorting chute 8.

By the way, the fine grains moving toward the outlet 39 side along the resistance plate 40 described above may be temporarily accumulated in the recesses due to the rounded serrated surface of the resistance plate 40, or the fine grains may collide with each other. It reaches the exit 39 while changing direction or rolling as appropriate.

Further, the fine particles are transferred to a flow regulating plate 6 provided at the outlet 39.
7 It is temporarily stored in a so-called stopper, and therefore only the fine grains that have been sorted by the above-mentioned rolling action are sent to the outlet 3.
9 through the first chute 7 into the gutter 104 of the grain sorting section B.

Next, the residue of the primary sorted grains that have fallen into the main sorting chute 8, that is, the waste particles, etc., fall to the center of the upper surface of the second sorting belt 6.

Then, secondary sorting is performed here by transporting the up-gradient belt 6, and the waste particles and foreign matter are transported by the belt 6 to its terminal end.

Further, the fine grains flow down to the starting end side of the belt 6 against the movement of the belt 6, are guided into the second chute 9 along the fin 86, and then pass through the chute 9 into the container 12. Fall.

The waste particles transferred by the belt 6 are sequentially thrown into a container 13 for storing waste from the third chute 10.

On the other hand, the fine grains introduced into the fine grain receiving trough 104, so-called hopper, of the grain sorting section B are introduced into the drum-shaped grain sorting net 103 by the iron bridge 104, and then are fed into the rotating iron net 103.
The grains are sorted by 03.

In other words, the small-diameter particles pass through the mesh of the particle selection screen 103 and exit the outlet 10.
5 and the downflow troughs 106, 107 into the container 115, and the large-diameter particles are guided to the inclined lower end side while rolling on the particle screening screen 103, and after reaching the inside of the cylindrical body 87 through the inside of the drum 101. , are sequentially introduced into the container 116 from the outlet 108 and the downflow gutter 109.

In short, the fine grains from the chute 7 are sorted by the grain sorting net 103, and the small diameter grains are put into one container 115, and the large diameter grains are put into the other container 116.

By the way, since a waste grain guiding chute 69 is provided at the higher end of the feeding end portion of the first sorting belt 5, the majority of the waste grains sorted by the belt 5 are directly transferred to the container 13 which is the third opening. As a result,
The amount of waste grains falling onto the second sorting belt 6 is reduced, the sorting load on the belt 6 is significantly reduced, and the re-sorting of fine grains and waste grains by the belt 6 can be smoothly performed. be.

As described in detail above, the present invention includes an endless first sorting belt 5 that sorts unsorted grains by dropping them onto the upper surface;
In a sorting machine comprising an endless second sorting belt 6 for re-sorting the sorting portions dropped from the feed end of the belt 5 via the main sorting chute 8, the feed end of the first sorting belt 5 is A waste particle guiding chute 69 for directly transferring waste particles from the upper side of the part to the third port, that is, the container 13.
, most of the waste grains (bad grains) and foreign matter sorted by the first sorting belt 5 can be directly dropped into the third port, and as a result, the second sorting belt 6 can This has the effect of making the re-election process extremely smooth.
