Description

[Detailed explanation of the invention] This invention uses a special feature in the throwing tube of the jump-lifting grain tube that is integrated into the huller, and the lifting wind is discharged outside the barrel before reaching the tip of the dumping tube. Jumping grain lifting is a method that attempts to suppress the floating of dust around the throwing tube as much as possible while slowing down the flow of grains lifted with the lifting wind to prevent the scattering of grains thrown out from the throwing tube. The purpose is to provide a dispensing tube for the tube.

That is, to explain this idea in detail below, A is a removing section consisting of a paddy tank 1 and a pair of removing rolls 2, etc., and B is a wind sorting section where the upper and rear walls are removed by a suction machine 3 at the front. The sorting air sucked in through intake ports 4 and 5, which are opened respectively, controls the sorting of the fallen rice from the removal section A and the sorting of the brown rice sorted in the sorting section C. 7 is a sliding rice jumping grain lifting machine, and 8 is a brown rice jumping grain lifting machine.

The sorting section C separates the fallen rice that has been deflated and sorted by the wind sorting section A and the wind sorting section B into brown rice and paddy. It is constructed integrally with a sorting section C placed above.

In the sorting section C, numerals 9 and 10 are primary and secondary sorting cylinders having a large number of recesses a formed in their inner circumferential surfaces, which are arranged vertically and are designed to be able to rotate in a substantially horizontal state. The supply side X and the discharge side Y are supported by rollers R, and the discharge side Y is installed adjacent to the removal section A.

Inside the primary sorting cylinder 9, a transfer device b is installed horizontally that transfers the scraped rice from the discharge side Y to the supply side X and drops it onto the inner peripheral surface of the sorting cylinder 9. In parallel, a receiving gutter 12 incorporating a screw conveyor 11 for taking out which receives the sorted rice scooped up by the depression a is installed horizontally, and the discharge side Y is made to look over the scooping tank 1.

Further, a receiving channel 13 for receiving the sorted rice scooped up by the recess a is installed horizontally within the secondary sorting cylinder 10, and 14 and 15 are provided on the supply side X and 1
The sorted rice received in the receiving gutter 12 in the next sorting cylinder 9 is
16 is a circulation path that communicates the discharge side Y of the secondary sorting cylinder 10 with the dropped rice jumping grain cylinder 7; 17 is the receiving gutter 13;
This is a channel for leading out the brown rice inside onto the flow down plate 18.

Next, T is a supply tank for dropped rice, which is attached to the side wall 19 on the upper side of the removal section A, that is, on the discharge side Y, and its lower part communicates with the starting end of the transfer device b, and the top plate 2
0 is fitted with the tip of the grain lifting cylinder of the sliding rice jumping grain lifting machine 7.

21 is a cross-sectional cover plate and is the bottom plate 1' of the paddy tank 1.
Thus, a paddy return path 22 is formed for guiding paddy from the discharge side Y of the primary sorting cylinder 9 to the paddy tank 1.

Next, 23 is a main cylinder of the brown rice jumping grain lifting machine 8, which is vertically erected, and one end of a curved cylinder 24 that can be curved downward is connected to the upper part of the main cylinder 23, so that the lifted grains rising inside the main cylinder 23 are directed downward. The proximal end 25a is bent at a nearly right angle, but the distal end side extends diagonally downward, slightly lower than horizontal, and the distal end 25a is bent at a nearly right angle.
6 is a dispensing tube bent downward, and the base end portion 25a is connected to the other end of the curved tube 24.
The upper surface 2 at the middle part of this dispensing cylinder 25
A lifting air outlet 27 is provided on the 5' or side surface 25'', and a mesh 28 with a mesh smaller than the lifting particles is provided in the opening 27.
is installed.

Therefore, the paddy supplied to the paddy tank 1 is slid down by a pair of de-rolls 2 and passed to the suction machine 3 in the wind sorting section B.
The rice is air-selected by the suction wind of the machine, and dust such as rice husks and rice husks are removed, and the fallen rice is lifted into the supply tank T by the hoisting machine 7 and supplied to the primary sorting cylinder 9 by the transfer device b. It will fall onto the inner peripheral surface of side X.

The scraped rice that has fallen into the primary sorting cylinder 9 is supported by the roller R and rotates in the recess a of the primary sorting cylinder 9.
While flowing due to the scooping action of
During the transfer to the transfer channel 14, 15, brown rice and a portion of the paddy are scooped up and dropped into the receiving trough 12.
The liquid then flows into the secondary sorting cylinder 10 to perform a secondary sorting action.

The sorting action in the secondary sorting cylinder 10 is similar to that in the primary sorting cylinder 9, but in the case of the primary sorting cylinder 9, the sorted materials scooped into the receiving gutter 12 are brown rice and a portion of brown rice. The secondary sorting cylinder 10 is adjusted so that only brown rice is scooped up into the receiving trough 13.

In addition, the paddy that was not scooped up by the primary sorting cylinder 9 is returned to the paddy tank 1 from the discharge side Y end via the return path 22, and is combined with the part of brown rice that was not scooped up by the secondary sorting cylinder 10. A portion of the paddy flows down in the circulation path 16 and is lifted up again by the sliding rice hoisting machine 7, and the brown rice scooped up into the receiving trough 13 flows down from the flow path 17 onto the falling plate 18 and is further lifted up. The fine dust is removed by the suction wind and taken out of the brown rice vaulting machine 8.

When taken out of the machine by this brown rice hoisting machine 8, the brown rice rises inside the main cylinder 23 by the jumping force of this hoisting machine 8 and wind power (lifting wind), and moves up into the bent pipe 24. The brown rice accompanied by the lifting wind that changed direction downward is transferred to the base end 25a of the dispensing tube 25, collides with a refracting surface that is almost at a right angle, and collides with the refracting surface at a nearly right angle. As shown by the arrow in FIG. 2, the direction inside the discharge tube 25 is changed mainly upward or to the side, and most of the uplifting wind is blown out of the tube from the mesh 28 of the jet nozzle 27.
The brown rice does not escape out of the cylinder by the net 28, but is separated from the lifting wind, and is decelerated and flows inside the dispensing cylinder 25 toward the tip 26, and is further turned downward by the tip 26, resulting in decayed residue. It falls gently along with the uplifting wind.

As described above, the present invention provides a vertical grain lifting machine for a huller that is integrally composed of a dehulling section, a winnowing section, a sorting section, a transfer path that communicates these parts, a jumping grain lifting machine, etc. One end of the curved tube that can be bent downward is connected to the upper part of the main tube to be installed, and the other end is bent at a nearly right angle with the base end extending slightly diagonally downward from the horizontal, and the tip end is bent downward. A dumping tube of a jump-lifting grain cylinder having a structure in which throwing tubes bent toward each other are connected, and a lifting air outlet is opened from the upper surface of the approximately middle part of the throwing tube or from the top surface to the side. Therefore, the grains are lifted by the joint action of the jumping force and the wind force (lifting wind), and the grains are separated from the lifting wind by a special structure of the throwing tube. The lifting wind is ejected outside the cylinder to reduce the flow velocity of the grains, causing them to fall gently from the tip of the discharging cylinder, thereby preventing grains from scattering and eliminating the phenomenon of dust scattering and floating. Can be done.
