Description

[Detailed description of the invention] The present invention provides a rotary sorting section that is integrally composed of a removing section and a wind sorting section. A rotatably horizontal sorting cylinder is provided in two stages, one on the supply side and the other end is on the discharge side, and the sorted grains are scooped up into a receiving gutter installed horizontally in the upper sorting cylinder. The bottom surface of each receiving gutter is tilted in the direction of the axis of rotation of the cylinder, and the sorted grains collected in the receiving gutter are removed from the sorting cylinder by gravity. The dust in the sorted grains is removed at the end of each receiving gutter, eliminating the need for a screw conveyor, etc. that was conventionally built into the receiving gutter, and particularly simplifying the power transmission system. To provide a sorted grain removal device in a rotary sorting huller that can improve the sorting action of a lower sorting cylinder and smoothly lead the sorted grains to the next process while reducing the weight of the machine body. It is in.

It goes without saying that the present invention can be easily implemented by making the diameter of the sorting cylinder relatively large and shortening the length from the supply side to the discharge side.

Hereinafter, description will be given with reference to embodiment figures.

A is the de-rolling section, which has a paddy tank 1 and a pair of de-rolls 2.
B is a wind sorting section where a suction machine 3 at the front removes the fallen rice from the removal section A by the sorting wind sucked in through intake ports 4 and 5 opened on the upper and rear walls, respectively. Sorting and wind sorting of the brown rice sorted in the rotary sorting section C are carried out. 6 is a sliding rice jumping grain lifting machine, and 7 is a brown rice jumping grain lifting machine.

The rotary sorting section C separates the grained rice that has been deflated and sorted by the discarding section A and the wind sorting section B into brown rice and paddy.
Each of these parts has a detached part A above the front part of the wind selection part B,
It is constructed integrally with a rotary sorting section C placed above the rear part.

In the rotary sorting section C, numerals 8 and 9 are primary and secondary sorting cylinders having a large number of recesses a formed in their inner circumferential surfaces, and are arranged in two stages, upper and lower, and are rotatable in a substantially horizontal state. The supply side X and the discharge side Y of grains to be sorted are supported by several rollers 10, and the discharge side Y is adjacent to the removal section A.

Inside the primary sorting cylinder 8, a transfer device using a screw conveyor b is installed horizontally to transfer the scraped rice from the discharge side Y to the supply side X and drop it onto the inner peripheral surface of the sorting cylinder 8. , a receiving gutter 11 for receiving the sorted grains scooped up by the recess a is provided parallel to the screw conveyor b when viewed from the rotational axis direction of the sorting cylinder 8, that is, from above, and the bottom surface of this receiving gutter 11 is 11' is inclined in the direction of the so-called rotation axis which is gradually lowered from the discharge side Y to the supply side X, and the discharge side Y end of this cylinder body 8 is exposed above the paddy tank 1. be.

Also, in the secondary sorting cylinder 9, similarly to the primary sorting cylinder 8, a receiving gutter 12 whose bottom surface 12' is inclined in the direction of the rotational axis of the sorting cylinder 9 is installed horizontally.

And each bottom surface 11' of the said receiving gutter 11, 12,
Separation nets 13 and 14 with meshes large enough to prevent the sorted grains from leaking are installed at the lower end of 12', and the lower sides of each of the separation nets 13 and 14 are directed toward the right side of the machine. Dust outflow gutters 15 and 16 opened
The upper side of each of the separation nets 13 and 14 is connected to a transfer gutter 17 that allows grains to be sorted to flow into the inner peripheral surface on the supply side X of the secondary sorting cylinder 9, and a wind selection section B.
They are respectively communicated with flow paths 18 that lead to the.

In addition, 19 is a circulation path that communicates the discharge side Y end of the secondary sorting cylinder 9 and the scraped rice jumping grain lifting machine 6, and 20 is a flow path 1.
8 is a falling plate for leading out the brown rice in wind separation part B, and T is a supply tank for the fallen rice, which is attached to the side wall 21 on the upper side of removal part A, that is, on the discharge side Y. It communicates with the starting end of the screw conveyor b, and the top plate 22 is fitted with the tip of the grain lifting cylinder of the dropped rice jumping grain lifting machine 6. 23 and 24 are gutter 1
1 and 12, the lower edges of which are pivotally connected to the upper edges of the adjustment plates 1 and 12, so that the inclination posture can be changed.

Therefore, the paddy supplied to the paddy tank 1 is de-rolled by a pair of de-rolls 2 and sent to the suction machine 3 in the wind sorting section B.
The fallen rice is sorted by the air sucked by the air, and the fallen rice is lifted into the supply tank T by the jumping grain lifting machine 6, and then transferred to the inner periphery of the supply side X of the primary sorting cylinder 8 by the screw conveyor b. It will fall onto the surface.

The scraped rice that has fallen into the primary sorting cylinder 8 is then flowed by the scooping action of the recess a of the sorting cylinder 8 which is supported by the rollers 10 and rotates, while flowing to the discharge side Y. While moving toward the bottom, brown rice and a portion of the paddy are scooped up and dropped into the receiving trough 11, and the dropped brown rice and a portion of the paddy flow down on the bottom surface 11' and are collected at the end of the flowing process. The dust contained in the dust is leaked from the separation net 13 and removed outside the machine by the dust outflow gutter 15 and transferred from the transfer gutter 17 to the secondary sorting cylinder 9.
The dust flows onto the inner circumferential surface of the cylinder and performs the same sorting action as the primary sorting cylinder 8, but the dust, etc. does not flow into the secondary sorting cylinder 9, and instead enters the recess a and changes its shape. Only brown rice is scooped up into the receiving gutter 12 and re-sorted while an efficient scooping action is performed without deformation. Since there is no dust in this scooped up brown rice, it flows down the bottom surface smoothly, and a small amount of dust further leaks from the separation net 14 and is removed outside the machine by the dust outflow gutter 16 and is removed from the flow path 18. After being further screened in the process of falling from the falling plate 20, the brown rice is taken out to a suitable location outside the machine by the vaulting machine 7.

In addition, the paddy that was not scooped up by the primary sorting cylinder 8 is returned to the paddy tank 1 from the discharge side Y end, and the part of brown rice that was not scooped up by the secondary sorting cylinder 9 and
The remaining paddy flows down in the circulation path 19 and is lifted up again into the supply tank T by the sliding rice hoisting machine 6.

As explained above, the present invention consists of a removing part, a wind sorting part, and a primary sorting tube with a large number of depressions formed on the inner peripheral surface, one end of which is a supply side for grains to be sorted, and the other end of which is a discharge side. The body and the secondary sorting cylinder are horizontally arranged in two stages, upper and lower, and a receiving gutter is installed in these sorting cylinders to take out the sorted grains scooped up by the above-mentioned recess.
Next, the sorted grains scooped up into the receiving gutter inside the sorting cylinder are
In a rotary sorting huller configured integrally with a rotary sorting section for re-sorting with a next sorting cylinder, the bottom surface of the receiving gutter is inclined in the direction of the rotation axis of the sorting cylinder. The sorted grains collected in the receiving trough are guided out by gravity, and the lower end of each bottom is provided with a separation net with a mesh that is large enough to prevent the sorted grains from leaking out. Not only does it not require a conveying device such as a screw conveyor to take out the sorted grains gathered in the receiving gutter, but the power transmission mechanism of this conveying device is no longer required, simplifying the structure and reducing weight. This not only eliminates the problems that can occur due to the conveyance device, such as the shifting of the surface of the brown rice, but also removes dust from the sorted grains with a separation net at the end of each receiving gutter, so that dust inside the secondary sorting cylinder is removed. Since the dust does not flow into the tube and the recesses on the inner surface of the lower sorting cylinder are not deformed, the sorting action can be improved.Moreover, the sorted grains flowing down the lower receiving gutter are not stagnated by the dust. This has the effect of allowing smooth flow to the next process.
