Description

[Detailed Description of the Invention] The present invention relates to a sorting machine for legumes such as soybeans, and particularly relates to an improvement in a sorting machine having a sorting belt.

As a sorter for spherical legumes such as soybeans, an endless sorting belt that rotates in a predetermined direction is lowered in the opposite direction of the upper surface of the belt and tilted in a direction that intersects with the direction of movement. There is one in which the beans to be sorted are allowed to flow down from the top of the slope to the bottom.

In this sorter, the beans to be sorted are sorted (
In the case of a complete column, the spherical shape is used to roll the sorted grains by tilting the sorting belt, allowing them to pass through a predetermined channel and being received from the lower part of the slope, where they are mixed into the grains to be sorted. Sorted materials (contaminants) such as broken beans, severely damaged grains, pebbles, small stems, leaves, and pods do not roll on the sorting belt, are placed on the sorting belt, are conveyed upward on an incline, and are discharged from the end of the conveyance. That's what I do.

However, when light-weight sorted materials such as small stems, leaves, and pods get on top of the granulation layer, which makes up the majority of the legumes fed to the sorting belt and moves in layers, it becomes a granulation layer. There was the inconvenience that they were moved together and detained without being sorted.

Therefore, in this invention, even if a light-weight material to be sorted gets on top of the granulation layer and moves, it is reliably dropped from the granulation layer onto the sorting belt and sorted. It is an object of the present invention to provide a pulse sorting machine that can reliably separate the sorted materials and improve sorting accuracy and sorting efficiency.

For this purpose, the present invention is characterized in that a plate-shaped resistance plate is disposed on the flow path of the sorted beans, with a gap slightly larger than the diameter of the beans and substantially parallel to the sorting belt surface. It is something.

Hereinafter, one embodiment of the present invention will be specifically described with reference to plan views.

In the figure, reference numeral 1 denotes a body frame of the sorting machine, and flexible wheels 2 are attached to the lower end of the frame 1 so that it can be moved.

A funnel-shaped hopper 3 is provided at the upper part of the frame 1, and its supply port 4 is opened downward toward one side of the frame. It is provided.

A wide sorting belt 5 is arranged below the supply port 4.

This sorting belt 5 is endlessly wound around a pair of rolls 6.6, rotates one of the rolls 6 in the direction of the arrow, and descends in the opposite direction to the direction of movement of the upper surface of the belt.
The supply port 4 is located at the upper part of the inclination, and the first chute is provided at the lower part of the inclination.

A flow resistance plate 8 having a sawtooth-shaped resistance portion is provided at the lower part of the slope of the upper surface of the sorting belt 5, and a flow resistance plate 8 is provided on the flow path 9 for the objects to be sorted formed on the sorting belt 5. A resistance face plate 10 is disposed such that one end overlaps the plate 8 and has a gap slightly larger than the diameter of the beans to be sorted between it and the upper surface of the sorting belt 5.

As shown in FIG. 3, the resistance face plate 10 has a recess 1 on the bottom surface.
0 a is formed.

In the pulse sorting machine having such a configuration, beans to be sorted, for example, soybeans containing impurities, are put into the hopper 3 and fed onto the sorting belt 5 through the supply port 4.

Since the sorting belt 5 rotates in the direction of the arrow and is tilted in a predetermined direction, the sorting belt moves in the flow path 9 while rolling in the tilted direction, and the flow resistance plate 8 provides resistance to the flow direction. The number of rotations of the particles increases, and the particles are brought to the chute 7 and stored in a container (not shown).

Sorting debris such as broken beans, severely damaged grains, pebbles, small stems, leaves, and pods that are mixed in the sorting process will not roll even if the sorting belt 5 is tilted, so they will not roll on the sorting belt 5. The material is conveyed in the rotational direction by riding on it, and is discharged from the terminal end.

During such sorting work, the soybean grains that make up the majority of the material to be sorted move through the channel 9 in a layer A as shown in Figure 2. Small stems and leaves among things,
Even if a light-weight sorted object B such as a pod gets on top of the object, it will be pressed by the resistance face plate 10 while moving through the channel 9, fall from the grading layer A onto the sorting belt 5, and move upward on the slope. It is transported and discharged.

Further, when the recess 10a is formed in the resistance face plate 10, the resistance to the sorted material changes and the falling from the granulation layer is promoted.

If the gap between the resistance face plate 10 and the sorting belt 5 is adjustable, the sorting accuracy can be improved and the versatility can be improved by adjusting the gap depending on the condition and type of beans.

As explained above, according to the pulse sorting machine of the present invention, the resistive face plate 10 is arranged on the sorting belt 5, with a gap slightly wider than the diameter of the beans to be sorted, and almost parallel to the sorting belt 5 surface. Since the sized grains flowing down on the sorting belt 5 move while rolling under the resistance face plate 10, even if a lighter weight sorted material may ride on the granulation layer, the sized grains can move under the resistance face plate 10. By making surface contact with 10 and preventing the particles from falling while moving while riding on the grading layer, the grading and the material to be sorted are reliably separated, improving sorting accuracy and efficiency. Wear.
