Description

[Detailed description of the invention] This invention supplies granular materials such as soybeans and adzuki beans onto the circumferential surface of a sorting belt whose circumferential surface is inclined in the direction of rotation and in the left and right directions perpendicular to the direction of rotation. , relates to a sorting device that selects and discharges distorted granular materials.

In this sorting belt, spherical particles that are easy to roll fall toward the lower part of the slope in the left and right direction, and distorted grains and flat grains that are difficult to roll are placed on the circumferential surface and are transferred and discharged toward the end of the rotation direction. Therefore, if the granules are directly fed from the hopper toward the lower left and right slopes on the circumferential surface of the sorting belt, the force of feeding will cause rejected grains and flat grains to mix with spherical particles and flow to the lower left and right slopes. It will fall down and the sorting accuracy will decrease.

For this reason, this idea was structured as follows.

That is, by tilting the end of the rotation direction high and in the left-right direction perpendicular to the rotation direction, the particulate matter is removed from the periphery of the sorting belt 1 from around the lower end to the left-right inclined high part on the rotation start side of the sorting belt 1. A hopper 2 is provided to cause the water to flow upward, and a guide frame 4 and a resistor 3 are provided on the rotation start end side and the left and right inclined lower portion sides of the hopper 2 to prevent the granules from falling. 3 and the guide frame 4, a gap L is formed between the guide frame 4 and the guide frame 4, through which a small amount of granular material passes in the left and right direction.

This invention has the following technical effects by constructing it in this way.

That is, since a guide frame 4 and a resistor 3 for preventing granular materials from falling are provided on the rotation start end side and the left and right inclined lower portion sides of the hopper 2, respectively, the granular materials supplied from the hopper 2 are As the sorting belt 1 rotates, an appropriate amount is supplied onto the circumferential surface of the sorting belt 1 from the inclined high part on the rotation end side of -2, so as mentioned above, the force of feeding the granules hinders the sorting. You will no longer be exposed to it.

Furthermore, if the supply of granules from the hopper 2 decreases, spherical granules tend to accumulate at the corners of the guide frame 4 and the resistor 3. Since a gap L is formed through which the particles pass in the direction, the spherical particles fall from this gap L towards the left and right inclined lower parts,
The granules supplied from hopper 2 are completely sorted.

Next, an embodiment of this invention will be explained with reference to the drawings.

The sorting belt 1 is a wide endless belt with fine irregularities formed on the circumferential surface, and is stretched around a pair of rolls 5 and 6.

A pair of rolls 5 and 6 are supported on a tilting frame 7, and this tilting frame 7
A motor 8 is attached to the chain wheel 1 fixed to the motor shaft 9.
A chain 13 is attached to a chain wheel 12 fixed to a roller shaft 11 and a roll shaft 11 to transmit power.

One end of the main shaft 14 that supports the tilting frame 7 is supported by a machine frame 16 via a universal joint 15, and the other end is supported by a vertical adjustment device 17.

The vertical adjustment device 17 is connected to a screw rod 18 across the front and rear machine frames 16.
and a sliding rod 19 are provided in parallel, and the lower end of the moving tool 20 screwed into the screw rod 18 and inserted into the sliding rod 19 and one end of the main support shaft 14 are connected by rods 21, 21. By rotating, the front and rear moving tools 20.20 move toward the center or move outward to move one end of the main support shaft 14 up and down.

The main support shaft 14 on the side of the universal joint 15 changes the inclination angle in the rotating direction of the sorting belt 1 by rotating the support shaft of the universal joint 15 with the right adjustment rod 22.

The hopper 2 is fixed to the tilting frame 7 by a horizontal rod 23, and a push plate 24 is installed at the left and right inclined lower parts of the discharge port and at the rotating base side of the sorting belt 1 to prevent granules from rising up on the sorting belt 1. The resistor 3 is provided on the tilting frame 7 so as to face the circumferential surface of the press plate 24, and the resistor 3 is fixed to the lower side of the push plate 24.

Reference numeral 4 denotes a guide frame for guiding the particulate matter to the horizontally inclined lower part, which is shaped unevenly in the rotating direction of the sorting belt 1, and is arranged so as to approach the end in the rotating direction one after another as it goes toward the horizontally inclined lower part.

A gap L is provided between the resistor 3 and the guide element through which one or two particles can pass through.

25 is a shutter that adjusts the opening degree of the discharge port of the hopper 2.

The granular material is supplied from the main hopper 26 of the machine frame 16, passes through the hopper 2, reaches the circumferential surface of the sorting belt 1, and is prevented from falling suddenly to the lower left and right inclined parts by the resistor 3, and is sorted. As the belt 1 rotates, it passes over the resistor 3 and is sequentially supplied onto the guide frame 4.

At that time, it passes through the gap L little by little or does not pass through due to a bridging phenomenon.

Finally, the particulate matter that is too small to overcome the resistor 3 is sorted out while moving along the guide frame 4 through the gap L.
