Description

[Detailed Description of the Invention] "Industrial Application Field" The present invention relates to an apparatus for sorting and selecting grains of, for example, soybeans or adzuki beans.

``Conventional technology'' Conventionally, the sorting belt was stretched at an angle to the front and back.
This belt is tilted in the left-right direction, and at the feed start end of the belt, unsorted grains are fed into the left and right inclined upper ends to separate them into sorted grains and waste grains, and unsorted grains are thrown in from the opening at the - side end, large and small. A device has been developed in which a cylindrical grain sorting net for separating grains into shaped grains is disposed below the belt, and the sorting and grain sorting operations of soybeans and the like can be carried out continuously.

"Problems to be Solved by the Invention" In the above-mentioned prior art, the sorting frame in which the sorting belt is installed is mounted on the machine frame in which the selecting net is installed, so that the support angle can be freely adjusted. Therefore, the belt angle adjustment means cannot be easily simplified, which makes the belt support structure complicated, and when cleaning the particle selection screen, etc., the belt etc. cannot be easily simplified. It was difficult to remove.

Further, since the selection hopper for inputting unselected grains of the grain sorting net was arranged below the sorting frame of the sorting belt, the hopper was built inside the machine frame of the said grain selection net, and therefore the grains were selected from the belt. It is not possible for the operator to easily confirm the sorted grains moving to the grain screen, and it is not possible to properly adjust the sorting of the belt. There was a problem in that it was difficult to charge the grains and it was not possible to perform work using only the grain sorting net.

However, the present invention includes a sorting frame in which the belt is installed and a machine frame in which the grain sorting net is installed, and the sorting frame is mounted on the machine frame so that the support angle can be freely adjusted. On the other hand, the horizontal inclination direction of the belt is aligned with the axis of the grain sorting net, and a selection hopper for unselected grains of the grain sorting net is placed in the sorting frame so as to face the lower end of the left and right inclination of the belt. They are installed side by side.

"Function" The inclination angle of the sorting belt can be changed by adjusting the support angle of the sorting frame, and the belt angle adjusting means can be easily simplified, so that the belt support structure can be configured more simply than before. At the same time, the sorting frame can be easily removed and cleaning of the sorting net inside the machine frame can be simplified compared to the conventional method, and the grain sorting hopper of the grain sorting net can be arranged parallel to the sorting frame. Therefore, it is possible to easily visually check the sorted grains moving from the belt to the grain sorting net in a part of the hopper, and it is possible to easily improve the sorting efficiency by the belt by grasping changes in the sorting situation more quickly than in the past. At the same time, the operator can directly input unsorted grains into the hopper and use only the grain sorting screen, making it more functional and extremely easy to handle than the conventional method.

It is carried into the supply tank 4 via the order t1, y-1-k18.

When the unsorted grains are dropped onto the primary sorting belts 5 and 6 via the feed o-ru 20 and shoe 23, 24, the sorted grains roll from the right-side inclined upper end of the belts 5 and 6 to the left-hand inclined lower end. Shoes 33 and 34, incomplete primary sorted grains such as immature grains and half-cracked grains are conveyed in a stationary state from the lower sloped ends on the feed start end side of the belts 5 and 6 to the sloped upper ends on the feed end side, and then to the chute. 35 to the secondary sorting belt 7.

Relatively well-shaped secondary sorted grains falling from the inclined lower end of the feed start end of the belt 7 are returned to the chute 15 via the chute 40.

Waste grains falling from the inclined upper end of the belt 7 on the feed end side fall into the container 42 via the chute 41 and are taken out of the machine.

Furthermore, the grain sorting hopper 43 is passed through the chute 33, 34.
When the sorted grains taken out are fed to the grain sorting net 8, the small grains are passed through the secondary grain sorting net 45, and the medium grains are passed through the secondary grain sorting net 46 through the outer openings of the screen 46. Large grains are stored in each container 54.
56 and 58, respectively, and the operator can directly put unsorted grains into the hopper 43 and use only the grain sorting net 8.

Further, as described above, the primary sorting frame 28 includes a motor 79, each belt 5, 6, chutes 33, 34, and a chain 83.
Since the frame 28 was installed independently from the machine frame 31, the machine frame 31
1 The inside can be easily cleaned, and the cassette system allows the belt 5.6 to be replaced with one of a different structure, and the inclination angle of the belt can be easily adjusted by adjusting the support angle of the sorting frame 28. , the support structure for the belts 5 and 6 can be easily configured, and the grains to be sorted are allowed to flow down from the upper right to the lower left for sorting, and the grains are sorted by flowing down from the upper left to the lower right; In other words, the sorted grains are made to flow down in a horizontal V-shape to perform sorting and sorting continuously, so the operator can visually check the sorted grains moving to the grain sorting hopper 43, improving work efficiency, while also reducing bulk processing. It is also possible to use only the particle selection screen 8, making it easy to handle.

"Effects of the invention" As is clear from the above embodiments, the present invention has the sorting belts 5 and 6 stretched in an inclined manner in the forward and backward feeding direction, and the belts 5 and 6.
. A cylindrical grain sorting net 8 for feeding and separating large and small grains is attached to the belts 5 and 6.

While placing the belts 5 and 8 on top of each other, align the left and right inclination directions of the belts 5 and 6 with the axial direction of the particle selection net 8, and
A selection hopper 43 for charging unselected grains of the grain selection net 8 facing the left and right inclined lower ends of the grain selection belt 5. 6 can be changed, the angle adjustment means for the belts 5 and 6 can be easily simplified, and the support structure for the belts 5 and 6 can be configured more simply than before, and the removal of the sorting frame 28 can be easily performed. It is easy to clean and the cleaning of the grain sorting net 8 inside the machine frame 31 can be simplified compared to the conventional method, and by arranging the grain sorting hopper 43 of the grain sorting net 8 in parallel with the sorting frame 28, the belt The sorted grains moving from the grain sorting nets 5 and 6 to the grain sorting net 8 can be easily visually confirmed in the hopper 43, and changes in the sorting situation can be grasped more quickly than in the past.
. It can be configured to be functional and extremely easy to handle, and in particular, by making the left and right inclination directions of the belts 5 and 6 coincide with the 8 axis direction of the grain sorting net, the conventional method differs by approximately 90 degrees. Compared to conventional technology, the horizontal width of the belts 5 and 6 can be made as large as the axial length of the grain sorting net 8 without increasing the size of the entire machine body, and the grain size adjustment of the belts 5 and 6 can be made larger. This provides practical effects such as being able to obtain a sufficient separation distance and grain selection distance of the grain selection net 8 with a compact configuration.
