Description

[Detailed description of the invention] The present invention relates to a sorting machine that sorts legumes such as soybeans and extracts fine grains (sorted grains). This invention relates to the improvement of a sorting machine that is configured to have a first sorting belt, and a main sorting chute to drop the waste grains, etc. that have been sorted by this belt onto a second sorting belt, where they are re-sorted by this second sorting belt. be.

In conventional sorting machines of this kind, when sorting soybeans with relatively large amounts of foreign matter and dirt, or soybeans with high water content, dirt, foreign matter, broken grains, etc. are placed on the main sorting chute. remains on this main sorting chute, and the remaining grains from the primary sorting that should be sent from the transfer end of the first sorting belt to the second sorting belt below it remain on this main sorting chute, and these remaining grains from the first sorting are transferred to the second sorting. There was a drawback that good re-sorting could not be carried out because the materials were not fed smoothly onto the belt and instead fell in lumps onto the belt.

One possible solution to this drawback is to make the angle of inclination of the main sorting chute steeper; however, increasing the angle of inclination of this chute is undesirable because the entire apparatus becomes bulky.

The present invention solves the above-mentioned conventional drawbacks, and includes at least horizontally suspending the first and second sorting belts, which are inclined in the feeding direction, in multiple upper and lower stages, and a main sorting chute that connects each of the belts in communication. In a sorting machine in which the chute is oscillated by a oscillating mechanism, the oscillating mechanism is driven by a pulley shaft of the first sorting belt, and a scattering prevention plate is erected on the upper surface of the second sorting belt, and the oscillating displacement is The exit side of the main sorting chute faces above the enclosure of the prevention plate, and the sorting residue from the first sorting belt containing dust is dispersed within the scattering prevention enclosure by the swinging of the chute. This eliminates the inconveniences that occur in the past, such as causing waste to accumulate on the top surface of the chute and reducing the sorting efficiency of the second sorting belt, and also significantly improves the re-sorting efficiency of the second sorting belt compared to the conventional method. In addition, by swinging the main sorting chute through the pulley shaft of the first sorting belt, a simple drive structure can be achieved regardless of the sorting angle adjustment of the first sorting belt. It is an object of the present invention to provide a sorting machine in which the chute can be appropriately oscillated.

The unsorted grains such as soybeans put into the hopper 4 are placed in the guide frame 3.
5 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. 2 and 3, the fine grains (sized grains) fit into the grooves 5a formed on the surface of the belt 5. without moving along the flow resistance plate 36 to the flow outlet.

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 exit side along the resistance plate 36 described above are caused by the rounded serrated surface of the resistance plate 36.
The fine particles may be temporarily accumulated in this recess, or may collide with each other and reach the outlet while changing direction or transferring as appropriate.

Further, the fine grains are temporarily stored in a flow regulating plate (not shown) provided at the outlet, so-called a stopper, and therefore only the fine grains that have been sorted by the above-mentioned rolling action are passed from the outlet through the first chute 7 into the container. 61.

Next, the remaining particles of the primary sorting column that have fallen into the main sorting chute 8 fall to the center of the upper surface of the second sorting belt 6 .

Then, secondary sorting is performed here by the transport of 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 62, 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.

By the way, the main sorting chute 8 is oscillated in the direction of the arrow in FIG. 3 about the oscillating fulcrum shaft 43 shown in FIG. Therefore, even when sorting grains with a relatively large amount of impurities and dirt, or grains with a high moisture content, the main sorting chute 8 is free of dirt, foreign matter, broken grains, etc. to stay,
This is prevented by the vibration of the chute 8, and the remaining grains from the primary sorting can smoothly fall onto the second sorting belt 6.

As a result, re-sorting by the second sorting belt 6 can be performed satisfactorily.

In addition, in the above embodiment, the thick portion cam 46 and the lever 47
Although the main sorting chute 8 is configured to be vibrated by an oscillating mechanism 45 consisting of a lever mount 48 and the like, the thick cam 46 may be replaced with another cam such as a follower cam, or even a crank mechanism. It goes without saying that the main sorting chute 8 may be configured to be vibrated by another vibrating device using, for example, a vibrator.

As is clear from the embodiments described above, the present invention has a main sorting belt in which the first and second sorting belts 5 and 6, which are inclined at least in the feeding direction, are horizontally suspended in upper and lower multiple stages, and the main sorting belts 5 and 6 are connected in communication with each other.

The chute 8 is arranged so as to face above the enclosure of the scattering prevention plates 38 to 41, and the sorting residue from the first sorting belt 5 mixed with dust can be dispersed and dropped within the enclosure of the scattering prevention plates 38 to 41 by the swinging of the chute 8. , it is possible to eliminate the conventional disadvantages such as the accumulation of waste on the upper surface of the chute 8 and reduce the sorting efficiency of the second sorting belt 6, and to significantly improve the re-sorting efficiency of the second sorting belt 6 compared to the conventional method. The sorting loss of the belt 6 can be drastically reduced by improving the belt 6, and the pulley shaft 2 of the first sorting belt 5 can
By swinging the main sorting chute 8 through the
The chute 8 can be appropriately oscillated with a simple drive structure regardless of the sorting angle adjustment of the first sorting belt 5, and the re-sorted grains are almost evenly distributed on the upper surface of the second sorting belt 6. By doing so, the second sorting belt 6
It is possible to easily increase the re-sorting throughput or the sorting speed, and it has remarkable effects such as being extremely functional and extremely practical compared to the conventional method.
