JPS5921904Y2 - Wind sorting device for rice huller - Google Patents

Description

[Detailed explanation of the idea] This project is an improvement of the wind sorting device of the rice huller.

In the conventional wind sorting device of a huller, an inclined flow path is provided below a pair of opposing dehulling rolls through which the removed material from the paddy flows, and an extension of the inclined flow path is formed in a porous wall. It is known to have a configuration such as Utility Model Application No. 53-37665, in which the punch is installed in a sorting air passage, and air is jetted through the porous wall to screen out the pieces to be removed and remove the pestle. In order to maintain good sorting accuracy of the wind sorting device, it is necessary to appropriately expand the wind sorting area, so the porous wall becomes longer, the air passage expands and becomes larger, and the machine height becomes higher. It had defects such as making hulling work inconvenient.

In general, the hulling machine must have its unhulling section located as low as possible to facilitate the loading of raw materials.

Therefore, this proposal lowers the overall height of the device by stopping the flow path between the porous wall and the secondary flow path of the inclined flow path in the wind selection section, and secondly, A flow path is provided, and the pestles are thoroughly sorted by wind selection twice before and after the primary and secondary stages, and the particles are removed from the machine by suction air, and the paddy loading port is made as low as possible, and the porous wall stroke is It is possible to perform a more complete wind selection than the conventional long and tall wind selection equipment.

The present invention will be explained with reference to embodiment figures.

A supply roll 2 is provided at the lower part of the paddy loading port 1, and a pair of dehulling rolls 3 and 4 are mounted opposite each other below the supply roll 2 to form a hulling chamber. An inclined flow channel 5 is installed in which the de-pulled mixed grains made of a brown rice mallet flow down, and the lower extension of the flow channel 5 is defined as a porous wall-secondary flow channel 6. The lower end portion is connected to one side edge portion 9 of a receiving trough 8 in which a conveyor 7 for paddy brown rice is installed, and the second flow path 6
A porous wall secondary flow path 10 having a reverse slope is installed oppositely, and its lower end is connected to the other end edge 11 of the receiving gutter 8, so that the secondary flow from the punching rolls 3 and 4 is The de-rodded mixed grains flowing down through the channel 6 toward the secondary channel 10 are screened by wind sucking upward from the bottom of each porous wall provided in both channels 6 and 10, and The particles mixed in the mixed grains are removed together with the wind through the sorting air passage 12 by the exhaust fan 13 to the outside of the machine.

In this way, the wind sorting device for the huller of the present invention has the porous wall-secondary flow path and the porous wall secondary flow path facing each other through the receiving gutter which is equipped with a conveyor for paddy and brown rice. Since the wind sorting area is divided into both porous walls and the height of the sorting air channel and the paddy tensioning port above it can be reduced, the overall machine height can be lowered as much as possible, and the height of the paddy tensioning port can be reduced as much as possible. It simplifies the work and improves work efficiency, and the wind sorting process is divided into two steps, the front and back, and the residue left in the first step is completely suctioned out in the second time, resulting in high-quality unhulled brown rice that does not contain foreign matter such as pestles. This has the effect of ensuring mixed grains.
