Description

[Detailed Description of the Invention] (a) Industrial Application Field The present invention is directed to a sorting cylinder that has a number of pot holes formed in its inner circumferential surface and is rotatably hung horizontally. In a pot-and-hole type sorting machine that sorts mixed grains by hand, the sorting barrel is configured to be removable and removable, leaving a receiving gutter, etc. provided in the sorting barrel, in order to perform cleaning and inspection of the sorting barrel, receiving gutter, etc. It is an object of the present invention to provide an easy-to-insert/extract device that can conveniently perform the insertion/extraction in various cases.

(b) Prior art As mentioned above, a jar is used to sort mixed grains by inserting a receiving gutter into the sorting barrel which has a number of holes formed in its inner circumferential surface and is rotatably suspended horizontally. For hole type sorting machines,
For example, as for the conventional technology,
As shown in Publication No. 55536, the side plate of the receiving gutter, which is used to catch the grains that are lifted up by the pot hole and fall in a parabolic pattern and flow into the receiving gutter, is fixed and integrated with the main body of the receiving gutter. In addition, it does not have a sensing valve for detecting the flow rate of mixed grains supplied into the sorting barrel.

Even though it is not equipped with a sensing valve, the side plate of the receiving gutter is used to guide the grains that are lifted up by the pot hole and fall in a parabola into the receiving gutter, so the upper end of the side plate is connected to the sorting cylinder. The closer the grain is to the inner circumferential surface of the groove, the better the grain will be received and flow into the receiving trough.

Therefore, if you try to insert or remove the sorting cylinder while leaving the receiving gutter etc., the inner peripheral surface of the sorting cylinder will interfere with the upper end of the receiving gutter side plate, making it impossible to insert and remove it smoothly and easily. The upper end of the side plate must be set at a certain distance from the inner peripheral surface of the sorting cylinder so that it does not interfere with it, otherwise the gutter side plate will not be able to fully fulfill its function. .

(C) Problems to be Solved by the Invention As described above, in the conventional system, the side plate of the receiving gutter is formed integrally with the main body of the receiving gutter, and even if the sorting cylinder is inserted or removed, the inner circumferential surface of the sorting cylinder does not close to the receiving gutter. If the gutter side plate interferes with the upper end of the gutter side plate, smooth and easy insertion and removal cannot be expected, and if it is possible to insert and remove the gutter side plate without interference, the function of the gutter side plate will be impaired. In addition to solving these shortcomings and fully fulfilling its functions, the system is also equipped with a sensing valve that detects the amount of mixed grains fed into the sorting barrel to automatically adjust the feeding amount. However, it was created with the aim of making the sorting cylinder smooth and easy to insert and remove by leaving the above-mentioned receiving trough and this sensing valve intact.

(d) Means for Solving the Problems Therefore, in order to achieve the above-mentioned object, the present invention provides a receiving gutter within the sorting barrel which is rotatably hung horizontally and has a large number of pot holes formed in its inner peripheral surface. In a pot hole type sorting machine, in which grains are lifted up by the pot hole are received between the inner circumferential surface of the sorting barrel and the receiving gutter within the downward rotating side of the sorting barrel. The gutter side plate that allows the flow to flow into the gutter,
A sensor is provided on the rotational axis side of the sorting cylinder so as to be able to change its posture, and inside the upward rotating side of the sorting cylinder, detects the amount of mixed grains flowing in the direction of rotation of the sorting cylinder. A sensing valve is installed, and the receiving gutter side plate and the sensing valve are configured to be able to change their posture together by being linked to the rotation axis of the sorting cylinder due to the rotation of the receiving gutter side plate. It is.

(E) Effect Since the present invention is constructed as described above, the receiving gutter which is inserted into the sorting cylinder which is rotatably hung horizontally by forming a large number of pot holes on the inner circumferential surface, can be inserted into the sorting cylinder and hung horizontally. As the grain rotates, the grains are lifted up by the pot hole and fall in a parabola pattern.The receiving gutter side plate catches the grains and allows them to flow into the receiving gutter and take them out. While being shifted in the direction of movement and sequentially flowing while forming a fluidized bed, it is lifted into the receiving gutter and sorted as described above.

In this case, if the amount of mixed grains supplied into the sorting barrel increases or decreases, the sensing valve detects this and automatically adjusts the amount of supplied grain, thereby stabilizing and smoothly performing the sorting operation.

Next, when the operation of the pothole type sorter is stopped and a cleaning inspection is performed, the sorting barrel is pulled out. At this time, the receiving gutter side plate is rotated so that it is positioned toward the rotation axis of the sorting barrel. If the position is changed, the sensing valves will be moved in conjunction with each other due to this attitude change, and will be concentrated on the above-mentioned rotation axis side, and will move away from the inner circumferential surface of the sorting cylinder.

Therefore, if the sorting cylinder is removed, the receiving gutter and sensing valve can be left behind and the sorting cylinder can be easily taken out. Also, to return to the original operating state, the operation can be performed in the opposite manner to the above.

(f) Examples The present invention will be specifically explained below with reference to examples.

The pot-hole type sorter shown in this example diagram is installed in a huller to sort mixed grains of brown rice and paddy after dehulling wind sorting, so first we will explain the outline of this huller. like this.

A is a shedding section, B is a wind sorting section, and C is a pot-and-hole type sorting machine equipped with a device according to the present invention. Place C,
These are integrated on a machine base 1 to constitute a huller.

The dehulling section A consists of a paddy tank 2 and a pair of dehulling rolls 3, etc., and the wind sorting section B is equipped with a suction dust remover 4 and a pressure fan 5 at the front and rear. The air outlet side of the pressure fan 5 is communicated with the front side and the rear side to form sorting air passages 6 and 7, and the front side sorting air passage 6
The husks from the husking section A are air-sorted to remove dust such as rice husks and rice cake to obtain mixed grains of brown rice and paddy, which are passed through the rear sorting air passage 7 to the pot-hole type sorter C. The selected brown rice is wind-sorted to remove waste rice.

The pothole type sorter C has a sorting barrel 11 which has a large number of potholes 8 formed in its inner circumferential surface and is rotatably mounted horizontally at the front and rear by a plurality of pairs of rollers 9, 9 and 10, 10. Two sorting sections C1 and C2, in which the receiving gutter 12 and the supply gutter 13 are inserted horizontally, are disposed above and below, and the mixed grains of brown rice and paddy obtained at the front side of the wind sorting section B are separated into brown rice. It is configured to sort into paddy.

Therefore, to describe the communication means of each of the above parts, 14 is a mixed grain distribution box, the lower part of which is branched, one side is connected to the supply gutter 13 of the upper sorting section C1, and the other is connected to the lower side and is connected to the lower sorting section C2. supply gutter 13
15 and 16 are brown rice removal channels.
This brown rice removal gutter 15 communicates with the upper receiving gutter 12,
The brown rice take-out gutter 16 inherits the brown rice taken out from the brown rice take-out gutter 15, and also serves as the lower receiving gutter 12.
The brown rice sorted in each of them is led out to the sorting air passage 7 on the rear side of the air sorting section B. 1
Numerals 7 and 18 are paddy return troughs, one of which receives the paddy flowing out from the inner peripheral surface of the upper sorting barrel 11 and returns it to the paddy tank 2, and the other paddy return trough 18 receives the paddy flowing out from the inner circumferential surface of the upper sorting barrel 11, and the other one receives the paddy flowing out from the inner peripheral surface of the upper sorting barrel 11 and returns the rice to the paddy tank 2. The paddy scooped up by grain lifting buckets 19 evenly distributed around the circumference is received and returned to the paddy tank 2.

In addition, 20, 20 are upper and lower supply gutter 13,
This is a drop opening for supplying mixed grains to each sorting cylinder 11 by opening the rear side of 13.

21 is a double elevator, which is the front one, and is connected to the wind selection section B.
The mixed grains of brown rice and paddy obtained in the above are lifted to the mixed grain distribution box 14, and the finished brown rice from which waste rice has been removed in the wind sorting section B is taken out to a suitable place outside the machine. ing.

The body of the pot-hole type sorter C has a front wall 22 and a rear wall 23 made of thin iron plates connected by a canopy 24, and the left and right sides connected by side plates 25 and 26 to form an almost airtight box. organized into shapes.

Next, the details of the upper and lower sorting sections C1 and C2 must be explained, except that the grain buckets 19 are evenly distributed in the sorting barrel 11 of the lower sorting section C2 as described above. Sorting section C1
Since the configuration is the same as that of the first embodiment, the upper sorting section C1 will be described, and the explanation of the lower sorting section C2 will be omitted.

The receiving gutter 12 and the supply gutter 13 of the upper sorting section C1
The front side is horizontally supported on the front wall 22 in a cantilever manner, and the rear side, which is the free end, is integrally fixed to the support plate body 27 which is a cutout at the top and bottom of a circular plate body. The shaft ends of the screw conveyors 28 and 29 installed in the receiving gutter 12 and the supply gutter 13 are inserted through and supported by the support plate body 27, and also supported by the fulcrum shaft 30 of the gate valve 30.
The a end is also supported by the support plate body 27.

The rear wall 23 has a large opening that allows the sorting barrel 11 to be freely inserted and removed outside the machine, and this opening and the support plate 27
A shielding plate 31 is fitted between the shielding plate 31 and the shielding plate 31 is tightened and fixed to the rear wall 23 and the support plate body 27 with several knob screws 32, and the support plate body 27 is firmly supported through the shielding plate 31. That's what I do.

Further, on the rear side of the sorting cylinder 11 through which the mixed grains are supplied from the dropping port 20, an overflow prevention wall 33 is formed by bending the end peripheral edge thereof, and a tongue piece is formed on the inner peripheral edge of this overflow prevention wall 33. An elastic annular body 34 made of rubber is integrally fitted to the shielding plate 31, and a cylindrical flange 35 whose outer circumferential surface is joined to the tongue of the elastic annular body 34 and is slightly tightened is integrally attached to the shielding plate 31. is attached to.

Note that 36 and 37 are transparent plates and opaque plates that close the upper and lower notches of the support plate 27, and 38 is the shaft end of the screw conveyor 28, 29 and the fulcrum shaft 30a of the gate valve 30. It is a box-shaped cover that covers the ends.

On the lower side of the sorting cylinder 11, there are two guide rails 39, 4 in the front and back direction as shown in the sorting cylinder 11.
0 are horizontally installed in parallel, and when the sorting cylinder 11 is in a rotatable state with the rolling surface 11a supported by the front and rear rollers 9, 9 and 10, 10, the first
As shown in the figure, the flange 11b and the guide rail 3
9 and 40 are designed to have a slight delay.

Therefore, when removing the sorting barrel 11 from the aircraft, first remove the cover 38 from the support plate 27, then remove the transparent plate 36 and the opaque plate 37, and then loosen the knob screw 32 to remove the shield. When the plate 31 is removed rearward from the rear wall 23, a cylindrical flange 35 is formed.
The rear wall 23 is also taken out and the rear wall 23 is left wide open.

At this time, the free ends of the receiving gutter 12, the supply gutter 13, and the like are integrally supported by the support plate 27 in a cantilevered manner.

Therefore, if the rear side of the sorting cylinder 11 is lifted a little more than the height of the flange 11b and pulled out rearward, the front side of the sorting cylinder 11 will be released from the supported state by the wheels 9, and at the same time, the flange 11b will be moved to the guide rail. 3
The sorting cylinder 11 is supported by coming into contact with the guide rails 39 and 40, and when pulled out further, the collar 11b touches the guide rails 39 and 4.
0 and was ejected from the aircraft body.

In addition, when inserting the extracted sorting barrel 11 into the outside of the machine, the flange 11b should be inserted into the guide rail 3.
If it is inserted while being supported by the guide rails 39 and 40, the rolling surface 11a will be placed on the wheels 9 and 9, and at the same time, the collar portion 11b will be inserted between the guide rails 39 and 40, following the reverse process of the extraction described above. 〓 and can be rotated.

Therefore, the configuration of the main parts of the present invention will be described. Since the upper sorting section C1 and the lower sorting section C2 are the same, only the upper sorting section will be described.

12a and 12b are a receiving gutter main body and a receiving gutter side plate that constitute the receiving gutter 12, and the receiving gutter side plate 12b is connected to the receiving gutter main body 12a and rotates in the direction of arrow A in which the sorting cylinder 11 rotates with its lower end as a fulcrum. It is movable and is kept in a position where its upper end approaches the inner circumferential surface of the sorting cylinder 11 by means of a suitable fixture. That is, the receiving gutter side plate 12b is located between the inner peripheral surface of the sorting cylinder 11 and the receiving gutter 12 (specifically, the receiving gutter main body 12a) within the downward rotation of the sorting cylinder 11 rotating in the direction of arrow A. It receives the grains lifted up by the pot hole 8 and allows them to flow into the receiving gutter 12 (specifically, the receiving gutter main body 12a), and is mounted on the rotation axis side of the sorting barrel 11 so as to be able to change its posture.

Further, 41 is the supply gutter 1 in the sorting cylinder 11.
A sensing valve installed vertically near the drop port 20 of No. 3 detects the mixture flowing while being deviated in the direction of rotation and forming a bulge within the upward circumference of the sorting cylinder 11 rotating in the direction A. Depending on the thickness of the fluidized bed of grains, it is attached to the inner peripheral surface of the sorting cylinder 11 so as to be able to move from or near the fulcrum shaft 42 at the upper end to detect the amount of mixed grains.

The fulcrum shaft 42 and the fulcrum shaft 30a of the gate valve 30 are connected to an arm 43 and a connecting rod 4 on the front side.
4. Interlockingly connected via arm 45, fulcrum shaft 30
A weight 46 for biasing the sensing valve 41 toward the inner circumferential surface of the sorting barrel 11 is attached to the rear side of the sensor a, and the weight 46 is housed within the cover 38.

Therefore, when the amount of mixed grains supplied into the sorting barrel 11 increases or decreases, the sensing valve 41 operates to follow the change in thickness of the fluidized bed, moving away from the inner circumferential surface of the sorting barrel 11. By operating this sensing valve 41, for example, the amount of paddy sliding from the paddy tank 2 can be decreased or increased to automatically adjust the amount supplied into the sorting cylinder 11, and at the same time, the tilted posture of the gate valve 30 can be changed. The amount of brown rice received into the receiving gutter 12 is adjusted to increase or decrease.

Further, the receiving gutter side plate 12b of the gate valve 30 can be freely engaged when the receiving gutter side plate 12b is rotated in the opposite direction to the rotation of the sorting barrel 11 in the A direction to cover the receiving gutter main body 12a. A locking tool 47 is fixed.

Therefore, as mentioned above, the sorting barrel 11 is designed to be able to be inserted and removed from the rear of the machine, but when it is inserted and removed, it is always sensed that it approaches the inner peripheral surface of the sorting barrel 11 due to the force of the weight 46. The gate valve 30 that acts on the valve 41 and the receiving gutter side plate 12b side to stand up is a second
Rotate the weight 4 as shown by arrow B in the figure.
When the gate valve 30 is tilted toward the supply gutter 13 against the biasing force of 6, the gutter side plate 12b comes to engage with the locking tool 47, and the sorting cylinder 11 of the gutter side plate 12b
The gate valve 30 due to a change in attitude toward the rotation axis of the gate valve 30
In conjunction with the tilting, the sensing valve 41 rotates as shown by arrow C and moves away from the inner peripheral surface of the sorting cylinder 11.

In other words, if the receiving gutter side plate 12b is rotated toward the rotation axis of the sorting barrel 11, the sensing valve 41 will also be rotated toward the rotating axis via the gate valve 30, etc.
2b and the sensing valve 41 are connected to the sorting cylinder 1 as shown in FIG.
The sorting cylinder 11 becomes concentrated in the center of the cylinder 1.
This makes insertion and removal smooth and easy.

(G) Effects of the Invention As detailed above, the present invention provides a pot formed by having a receiving gutter inserted through a sorting barrel that is horizontally suspended by forming a large number of pot holes in its inner circumferential surface so as to be rotatable horizontally. In a hole-type sorter, a receiving gutter side plate that receives grains lifted up by a pot hole between the inner circumferential surface of the sorting cylinder and the receiving gutter within the downward rotating side of the sorting cylinder and allows the grains to flow into the receiving gutter. is provided on the rotational axis side of the sorting cylinder so that its posture can be changed freely, and in the upward circumferential side of the sorting cylinder, a mixed grain quantity which is deviated toward the rotational direction of the sorting cylinder and flows. A sensing valve for detection is installed, and the receiving gutter side plate and the sensing valve are linked to the rotation axis side of the sorting cylinder due to the rotation of the receiving gutter side plate, so that the posture can be changed together. Because of this structure, the upper end of the side plate of the receiving gutter is located close to the inner circumferential surface of the sorting barrel, which improves the reception of the grains lifted by the pot hole and the flow into the receiving gutter, and at the same time allows for sensing. The valves follow the increase/decrease in the amount of mixed grains supplied into the sorting barrel and automatically adjust the supply amount and increase/decrease the amount of grains received into the receiving trough, each of which fully fulfills its original function. However, when inserting or removing the sorting cylinder while leaving the receiving gutter and sensing valve behind, the rotation axis moves away from the inner circumferential surface of the sorting cylinder due to the interaction with the sensing valve caused by the change in the attitude of the receiving gutter side plate. Since the core changes its posture and is concentrated in the center of the sorting cylinder, there is no risk that the inner peripheral surface of the sorting cylinder will interfere with the receiving gutter side plate or the sensing valve, and the insertion and removal can be done smoothly. Since there is no interference, there is no damage to the gutter side plate or sensing valve.

As described in the embodiment of the present invention, if the sensing valve is configured to operate in conjunction with the rotation of the receiving gutter side plate, the rear end of the receiving gutter side plate will be located near the rear wall of the aircraft. The opening for inserting and removing the sorting cylinder is very convenient and the position of the sorting cylinder can be easily changed.
