Description

Detailed Description of the Invention (Industrial Field of Application) This is a system that supplies paddy to a roll-type huller that removes paddy by scraping it between a pair of elastic rolls that rotate at different circumferential speeds. This invention relates to a device for

(Prior Art) Conventionally, paddy is merely dropped and fed from above between a pair of elastic rolls using a feed roll or the like having protrusions on the outer periphery.

(Problem to be solved by the invention) Therefore, it is unavoidable that the amount of paddy supplied becomes uneven, and if it is too large, the paddy that falls will stagnate between the pair of left and right elastic rolls, resulting in broken rice. Or, if the paddy that has fallen sideways passes between a pair of elastic rolls with its axial direction parallel to the contact surface of the elastic rolls and is not dehulled, and if there is too little, power is wasted. However, the efficiency of rice hulling decreases.

The present invention aims to solve the above-mentioned drawbacks by feeding rice evenly onto the contact surfaces of a pair of left and right elastic rolls so that the axial direction thereof is perpendicular.

(Means for solving the problem) Reference numeral 1 denotes a supply port that looks above the left and right pair of elastic rolls 2.2, which has a wide funnel-shaped opening at the top, and the paddy is passed through so that its axial direction is vertical. The holes 3 are arranged parallel to the contact surfaces of the left and right elastic rolls 2.2.

Reference numeral 4 denotes a diaphragm that reciprocates in a direction parallel to the contact surface of the elastic roll 2, vibrates by an appropriate vibration mechanism (not shown), and connects each drop hole 5 with a diameter slightly larger than the lower diameter of the through hole 3. It is bored opposite to hole 3.

(Function) The paddy supplied into the supply port 1 enters through the funnel-shaped opening at the top of each through hole 3 while its axial direction is vertically corrected.
When the lower end of the rice protrudes from the through hole 3, the vibration plate 4 falls into the hole 5.
It touches the inner wall of the wall and falls, and it touches the contact surfaces of a pair of left and right elastic rolls 2.2 and escapes.

(Example) The elastic rolls 2.2 are made of rubber or synthetic resin, and one roll rotates at a faster circumferential speed than the other.

Reference numeral 6 denotes a support bar on the side edge of the diaphragm 4.

(Effects of the Invention) In the present invention, since the upper part of the through hole 3 has a wide funnel-shaped opening, the paddy in the supply port 1 is guided into the funnel-shaped opening and its axial direction is corrected vertically. When the lower end of the paddy protrudes from the through holes 3, it touches the inner wall of the drop hole 5, which is slightly larger in diameter than the lower part of the through hole 3 of the reciprocating diaphragm 4, and falls quickly. Therefore, there is no risk of blocking the through hole 3.

Moreover, each through hole 3 has a drop hole 5 as well as left and right elastic rolls 2.
Since the falling paddy is parallel to the contact surface of roll 2.2, the 6 dropped paddy grains can pass through the contact surface of the left and right rolls 2.2 smoothly and evenly without stagnation while keeping the axial direction perpendicular, so a large amount of paddy can be produced in a short time. Completely and efficiently remove the walls without leaving any unremoved rice. This effect is produced.
