Description

[Detailed description of the invention] The present invention relates to a rotary sorting huller that employs a rotating sorting section to sort paddy and brown rice. Conventionally, the sorting cylinder of this rotating sorting section was horizontally suspended in a substantially horizontal state. In the process of gradually flowing the mixed grain from the supply side to the discharge side, it is sorted into paddy and unpolished rice by the scooping action of the depressions, so the time required from the supply side to the discharge side is long, and differences in varieties occur. Depending on the conditions such as the discharge rate and removal rate, the entire stroke of the sorting tube may not be used and the discharge side may idle, resulting in poor sorting efficiency.

Therefore, in order to always use the entire stroke of the sorting tube, the sorting tube was placed on the rear part of the wind sorting section with the supply side at the rear and the discharge side at the front. By configuring the shape plate that covers the part so that it can be adjusted downwardly, the supply side of the sorting cylinder is appropriately raised higher than the discharge side, reducing the time required for mixed grains to flow from the supply side to the discharge side, thereby improving efficiency. To provide a rotary sorting and hulling machine which contributes to improving the quality of rice, stabilizes the machine body, and covers the rear end of the machine stand to prevent damage thereto.

This invention will be described below with reference to embodiment figures.

A is a de-rolling part that stores a paddy tank 1 and a pair of unrolled rice 2, B is a wind sorting part which is equipped with a suction device 3 at the front end and forms a suction air passage ₄ ,
The suction air from the suction machine 3 and the pressure winch 5 and the pressure air are transferred from the pressure path 6 to the inside of the suction air path 4 by communicating with the brown rice sorting section B ₂ which is equipped with a pressure-air kink 5 at the rear and forms a pressure-air path 6 . 7 is a rice gutter, 8 is a second gutter, 9 is a brown rice gutter, and 10 is a suction air path 4 for taking out the air-selected rice to the outside of the machine. This is an escape rate confirmation valve that can be opened and closed to check the escape state.

Reference numeral C denotes a rotating sorting section, both of which have a large number of depressions 12 formed on their inner circumferential surfaces, and can be rotated by being supported by several wheels 13 so that one end is the supply side X and the other end is the discharge side Y. A primary sorting tube a and a secondary sorting tube b are arranged horizontally on top of each other, and the removal section A is a separated rice sorting section.
On top of B ₁ , this rotary sorting section C is brown rice sorting section B ₂
It is posted above.

In this case, the primary sorting cylinder a is mounted with the supply side X at the rear and the discharge side Y at the front, and the discharge side Y is adjacent to the removal section A.

Inside the primary sorting tube a, from the supply side 15 and 16 have screw conveyor 17
is built in, and a supply port 18 is opened on the supply side X of the dropped rice supply gutter 14.

19 is the discharge side Y of the rotary sorting section C, that is, the paddy tank 1
It is a dropped rice tank installed above, and its upper part is connected to the upper part of the grain lifting machine D installed upright on the left side of the machine body, and the lower part is connected to the starting end of the dropped rice supply gutter 14. The lower part of the machine D is connected to the sliding rice gutter 7 of the wind sorting section B.

Also, in the secondary sorting tube b, similar to the primary sorting tube a, a refinish sorting grain receiving trough 20 with a built-in screw conveyor is installed horizontally from the supply side X to the discharge side Y.

E is a vertical line rice sorting machine installed diagonally on the supply side The small particles contained in the sorted grains are removed while the sorted grains in the finished sorted grain receivers 15, which are connected to the starting ends of the refinished and sorted grain receivers 20 in the sorting cylinder b, reach the refinished and sorted grain receivers 20. It is configured to be removed.

The terminal end of the re-sorted grain receiving trough 16 of the primary sorting tube a communicates with the inside of the secondary sorting tube b through the supply tube 23 whose lower part is inserted into the supply side X in the secondary sorting tube b. The sorted grains in the receiving trough 16 are subjected to the sorting action again in the secondary sorting tube b.

The discharge side Y end of the primary sorting tube a is exposed above the paddy tank 1, and the discharge side Y end of the secondary sorting tube b is connected to the sliding rice gutter 7 by the diagonally installed reduction plate 24. The terminal end of the refinishing sorting grain receiving trough 20 communicates through a flow path 25 onto a flow down plate 26 provided obliquely in the brown rice sorting section _B2 .

Next, F is a shaped plate attached to the rear ends of the machine bases 27 and 28 on both the left and right sides, and upward support plates 29 and 30 are welded to both sides of the front part, and the upper parts of these support plates 29 and 30 are attached to the machine bases. A horizontal shaft 31 inserted through the rear ends of 27 and 28
The horizontal shaft 31 is used as a fulcrum to rotate the horizontal shaft 31, and reference numeral 32 denotes adjusting bolts screwed in the vertical direction at the rear ends of the machine bases 27 and 28. It is configured to be pressed down and moved downward about the horizontal shaft 31 as a fulcrum.

The bent portion 33 covers the rear end portions of the machine bases 27 and 28.

Next, the operation of the present invention with the above configuration will be explained. The power of the prime mover is transmitted to each part of the removing section A, the wind sorting section B, the rotary sorting section C, and the grain lifting machine D through appropriate transmission devices.

Therefore, the paddy supplied to the paddy tank 1 is slid down by a pair of de-rolls 2, and is wind-selected in a suction air path 4 to remove second grains, chaff, and dust, and collect in the sliding rice trough 7. The grains are transferred to the left side of the machine by a screw conveyor and lifted into the scraped rice tank 19 by a grain lifting machine D.

The lifted rice (mixed grains of brown rice and paddy) is transported from the lower part of the rice tank 19 to the rear in the primary sorting tube a through the rice supply gutter 14, and then passed through the supply port 18 for sorting. It falls onto the inner peripheral surface of tube a.

The falling mixed grains are in a raised state at the time of falling from the supply port 18 due to the scooping action of the depression 12 by the rotation of the primary sorting tube a which rotates in the direction of arrow A in Fig. 3. However, it gradually becomes unevenly distributed in the direction of rotation and moves from the supply side The brown rice that has settled in the recess 12 is scooped up, reaches the upper part, escapes from the recess 12, and falls into the finish sorting grain receiving trough 15 or the re-sorting grain receiving trough 16 in a parabolic manner. Because the paddy mainly floats to the upper layer and has a large grain shape, it is difficult to fit into the recess 12, or even if it does, it is easy to fall out. Gutter 16
Small grains of brown rice fall into the hollow 1.
2 and is difficult to remove, it is lifted to the top and reaches the finish sorting grain receiving trough 15. In addition, the paddy and brown rice that do not fit into the recess 12 and reach the re-sorting grain receiving trough 16 flow in a direction opposite to the direction A, and move to the discharge side Y while repeating this state.

Therefore, fine grains and small grains of brown rice are scooped up into the final sorting grain receiving trough 15, and mixed grains of brown rice containing some paddy are scooped up into the re-sorting grain receiving trough 16. The brown rice in the gutter 15 is transferred backwards by the screw conveyor 17, passes through the discharge pipe 21 from the terminal end, and reaches the rice sorter E, where the small grains leak and are removed outside the machine, and the fine grains that do not leak are removed. The particles flow from the receiving tube 22 into the re-sorting grain receiving trough 20 in the secondary sorting tube b.

In addition, the mixed grains in the other re-sorting grain receiving trough 16 are similarly transferred rearward and passed through the supply tube 23 from the terminal end to the second
It is supplied onto the inner circumferential surface of the supply side X of the next sorting tube b.

The supplied mixed grains are repeatedly subjected to the sorting action of being scooped up by the recesses 12 rotating in the same direction as shown by the arrow B in FIG. 3, similar to the primary sorting tube a.

This scooping action by the recess 12 is such that in the primary sorting tube a, only the paddy is returned to the paddy tank 1 from the discharge side Y end as shown by the arrow C in Figure 1, so that it is subjected to the re-demolition action. and the secondary sorting tube b
In this case, only brown rice is allowed to fall into the refinishing sorting grain receiving trough 20, so that some mixed grains of paddy and brown rice are collected from the discharge side Y end of the secondary sorting tube b as shown by arrow D in Figure 1. It flows down onto the reduction plate 24 and is screened again, and then falls into the fallen rice gutter 7 where it joins with new fallen rice, and the brown rice in the refinishing and sorting grain receiving gutter 20 flows through the flow path. 25, passes through the flow plate 26, is air-selected in the air pressure path 6, collects in the brown rice gutter 9, is transferred to the side, and is taken out to a predetermined location by a thrower.

In this way, the paddy and brown rice are sorted by the scooping action of the depressions 12 in the primary sorting tube a and the secondary sorting tube b, but the shape of the paddy and brown rice varies depending on the variety, and in the case of small grains. hollow 1
The scooping action by 2 becomes vigorous, and the scooping action is also promoted when the escape rate is high.

Therefore, when the above-mentioned scooping action is vigorous and promoted, the entire process of each sorting cylinder a, b from the supply side The lifting action is completed, and the stroke from this midway point to the discharge side Y end is idling.

In this case, as shown in FIG. 4, by rotating each of the adjustment bolts 32 to press downwardly the shape plates F on both the left and right sides, the horizontal shaft 31 will rotate downwards using the horizontal shaft 31 as a fulcrum, and at the same time press the ground plane. to raise the rear of the aircraft. Then, the primary sorting tube a and the secondary sorting tube b change from a nearly horizontal posture in the front-rear direction to an inclined posture with the supply side X high and the discharge side Y low, and the flow from the supply side X toward the discharge side Y. As the mixed grains move, the moving speed increases, and the scooping action by the depressions 12 extends to the discharge side Y during idle rotation, and is carried out throughout the entire stroke.

As a result, the time required for moving from the supply side X to the discharge side Y while flowing is shortened, and the sorting capacity is improved.

Incidentally, the ground plane of the form plate F is not necessarily flat, and if the fuselage is tilted in the left-right direction, it is corrected to a horizontal state using the respective adjustment bolts 32.

In addition, after loading this rotary sorting rice huller on the platform of a transport vehicle and transporting it to the destination, when unloading it from the platform, it is easier to unload it from the rear of the machine because it is relatively light. Then, the rear ends of both left and right sides touch the ground to set the aircraft in a tilted position.Then, the rear ends that are in contact with the ground slide on the ground, and the front side of the aircraft is lowered from the loading platform to a horizontal position to complete unloading from the loading platform. At this time, the shape plate F covers the rear end portions of the machine bases 27 and 28 to protect them and prevent damage.

As described in detail above, the present invention has a large number of depressions large enough to fit brown rice into the removing part, wind sorting part, and inner peripheral surface, one end of which is the supply side for mixed grains, and the other end is the discharge side. In the rotary sorting huller, which is integrally configured with a rotary sorting section in which a sorting cylinder is rotatably horizontally mounted and a rotary sorting section is equipped with a receiving gutter for taking out the brown rice scooped up by the above-mentioned depression, the wind sorting The removal part is mounted on the front part of the machine, and the rotary sorting part is mounted on the rear part of the machine. In addition to attaching a shape plate to cover the area, this shape plate is configured so that it can be freely adjusted downward, so depending on the conditions such as different varieties of unhulled brown rice or high shedding rate, the scooping action by the hollow can be strong. In addition, the whole process from the supply side to the discharge side of the sorting cylinder is not used, and the part on the discharge side idles, and the time required to move through the whole process is long, which adversely affects the sorting efficiency. However, in this case, the rear ends of both sides of the machine table were floated and the sorting cylinder was immediately changed to an inclined position where the supply side was high and the discharge side was low, thereby eliminating the above-mentioned idling phenomenon and shortening the time required for sorting. Efficiency is improved, and since the rotary sorting section is mounted with the supply side at the rear and the discharge side at the front, it is possible to easily change the position to an inclined position in which the supply side is raised.

In addition, the bent part of the shape plate covers the rear end of the machine base, so when this rotary sorting huller is loaded onto the platform of a transport vehicle and transported to the destination, when unloading it from the platform. I try to lower the rear of the aircraft, which is relatively light, but at the same time, I place the rear ends of the aircraft on both the left and right sides in contact with the ground and place it in a tilted position.
Next, the rear end of the aircraft is slid against the ground, and the front side of the aircraft is lowered from the loading platform to a horizontal position to complete the unloading operation from the loading platform. This has resulted in a number of advantages, including the fact that the rear end of the machine base is not damaged even by contact with the ground and sliding, thereby protecting it.
