Description

[Detailed Description of the Invention] The present invention relates to a sorting/grain transporting device in which a cylindrical sorter is configured so that it can also be used as a grain transporting device.

In the first place, in the case of paddy rice, mold grows on the ears of rice, which in some places turn yellow depending on the climatic conditions of the year, such as humidity and temperature, from the earing stage. That is, mold is attached to all or part of the surface of the rice grains attached to the stems, and this rice grain is generally called rice kojimomi (rice kojimomi), and its grain size is considerably larger than that of normal rice grains.

If such rice husks are harvested using a combine harvester in a field where such husks have occurred, this rice husks will be mixed into the raw rice, and even if it is dried, it will not be dried due to the mold attached to it. As a result, the quality of rice deteriorates.

Furthermore, if this rice husk is removed along with normal rice, the rice husk will not be dried enough and will contain moisture that is close to raw, so some will be compressed by the rubber rolls and become flat, and some will have mold attached to them. The particles are exfoliated and become particles approximately the same size as brown rice grains, and are mixed into the brown rice.

Therefore, it has become necessary to remove the above-mentioned rice husks in a step before the hulling process and perform the hulling operation.

Therefore, in the hulling process for normal paddy, a grain carrying device lifts the paddy to the dehulling section and supplies it, and if rice koji is mixed in, a sorter is used to remove the rice koji and produce normal paddy. The purpose is to obtain brown rice of good quality and sorting even if it is from a field where rice koji is produced by hulling, and to use one product appropriately and conveniently depending on the condition of the paddy. .

Hereinafter, the present invention will be explained with reference to embodiment figures.

First, we will discuss the form of the sorting machine when the rice husk is mixed in.

1 has a rectangular shape and is open at the top, and the bottom part 2 is in the shape of an inverted eight, and the center part of the bottom part 2 has an X on the starting side.
A transverse conveying path 4 containing a built-in screw conveyor 3 is provided horizontally from Y to the terminal end side, and a lifting path 5 communicating therewith is provided in the vertical direction on the terminal end side of this transverse conveying path 4.

Reference numeral 6 denotes a sorting tube, and a number of sorting holes 7, which are long in the rotating direction of the sorting tube 6 and are large enough to pass normal paddy, are bored on the circumferential surface in a staggered manner. The boss portions 8 and 9 are located at the axial center position of the support rod 10,
11.

Reference numeral 12 denotes a support shaft with a head 12a that is supported on the machine wall 13 on the starting end side
By attaching the head 12a, the head 12a receives a pressing force and is fixed. Reference numeral 14 denotes an annular guide plate fixedly installed inside the machine wall 13 concentrically with the support shaft 12. 1
5 is an opening bored in the machine wall 13 above the fixed lower end of this guide plate 14, 16 is a tank with telescopic legs 16a, and its supply port 16b is insertable into the opening 15; This is a butterfly bolt for fixing the tank 16.

Reference numeral 18 denotes a rotating shaft which is supported by the machine wall at the terminal end Y and rotates in an inwardly protruding state, and a rectangular fitting portion 18a is formed at the inner tip.

The boss portion 9 is formed into a rectangular hole corresponding to the fitting portion 18a.
19 is an annular cover that covers the rotary shaft 18. The sorting tube 6 can be freely inserted and removed only in the axial direction.

In addition, M is a prime mover, 20 is a transmission part which rotates the screw conveyor 3 from the prime mover M, and 21 is an intermediate shaft which receives the power of this transmission part 20 and derives the power from the starting end side X to the terminal end side Y. , 22 is the terminal side Y
This is a transmission section that rotates the rotating shaft 18 from the intermediate shaft 21.

Further, an arc-shaped partition plate 23 is provided on the outer circumferential portion of the sorting tube 6 near the terminal Y end thereof, which is close to the outer circumferential surface of the sorting tube 6 and partitions the inside of the machine casing 1 leaving only the traversing path 4. A portion of the screw conveyor 3 installed horizontally between the partition plate 23 and the other end side Y machine wall is covered with a chevron-shaped enclosure plate 24, and on both sides of this enclosure plate 24 there are outlet ports 25 facing downward. Open. 1a
is a cover that covers the upper open part of the machine case 1.

Next, reference numeral 26 denotes an opening opened in a side wall 27 near the terminal end Y of the machine housing 1. This opening 26 is located on the bottom plate 2, and is opened to allow the supply port 16b of the tank 16 to be inserted and removed.

Therefore, when rice husks are mixed in normal paddy, the cylindrical sorting machine shown in Figs. It supplies it to the machine. That is, the grains to be sorted (paddy mixed with rice husk) inputted into the tank 16 are sequentially supplied to the inner peripheral surface of the starting end side X of the sorting tube 6 via the guide plate 14 from the supply port 16b. In this case, the prime mover M
The power is transmitted to the rotating shaft 18 via the intermediate shaft 21 and the transmitting section 22 of the transmission section 20, and the boss section 9 of the sorting tube 6 is connected to the fitting section 18a of the rotating shaft 18 at the square portions of the sorting tube. 6 rotates at a low speed in the direction of the arrow (shown in FIG. 3), and the cross-feeding path 4 and lifting path 5 are also in operation, and the grains to be sorted supplied to the sorting tube 6 are at the other end side Y, which is at a lower level. In the process of flowing towards the bottom, normal size paddy passes through the sorting hole 7, flows down along the bottom 2, enters the cross-transfer route 4, is transferred from the terminal to the lifting route 5, and after being lifted. The rice koji that is supplied to the huller and does not leak from the sorting hole 7 of the sorting tube 6 flows inside the sorting tube 6 to the terminal side Y, falls from the end onto the shroud 24, and is distributed to both sides. and is taken out from the machine casing 1 through the take-out port 25.

Next, if there is no rice husk mixed in and there is only normal paddy, it is used as a grain carrying device and immediately supplied to the huller.
Remove the butterfly bolt 17 tightened to the machine wall 1.
3, the supply port 16b will come out of the opening 15 and the tank 16 can be easily removed from the machine casing 1. The removed tank 16 is opened near the terminal end Y of the machine casing 1 by adjusting its telescoping legs 16a.
If the supply port 16b of the tank 16 is inserted into the tank 6 and the tank 16 is fastened to the side wall 27 with the butterfly bolt 17, a grain carrying device can be obtained. (Indicated by imaginary lines in FIGS. 1 to 3.) In this case, if a belt clutch (not shown) is installed to interrupt the power transmission to the intermediate shaft 21, the rotation to the sorting tube 6 can be interrupted. I feel better now. Therefore, the tank 16 becomes a tensioning hopper near the other end Y, and if normal paddy is put into this tensioning hopper, it will flow directly into the cross-transfer route 4 from the supply port 16b, and the paddy will be removed from the lifting route 5. It will be supplied to the sliding machine.

Moreover, in order to convert this grain carrying device into a cylindrical sorting machine, the tank 16 can be attached to the starting end side X of the machine casing 1 in its original state by performing the operation opposite to the above.

Incidentally, the sorting hole 7 of the sorting tube 6 is clogged with grains to be sorted, but by pressing the removal plate 27 against the outer peripheral surface in the state shown in FIG. 3, the particles are pushed inward and removed. It is. That is, on the upper surface 27a of this removal plate 27, that is, on the contact surface with the sorting cylinder 6, slightly long protrusions 28 are arranged in a row as shown in FIGS. 4A and 4B. Since the removing plate 27 and the protrusion 28 are made of an integrally molded product, they have elasticity and toughness, so that even grains of rice, etc. that are strongly agitated in the sorting hole 7, can be bounced inward to remove clogging materials and sort them. It can be said that it is effective.

As detailed above, the present invention has a cross-feeding path horizontally installed at the bottom of the machine casing, the end of which is connected to the lifting path, and normal paddy passes on the circumferential surface above the cross-feeding path within the machine casing. A sorting cylinder having a large number of sorting holes of about 100 degrees is horizontally mounted so as to be rotatable with the starting end thereof placed at a high position and the terminal end thereof placed at a low position, and the starting end side of the machine casing is communicated with the inner circumferential surface of this sorting cylinder. The tank is attached so that it can be attached freely, and an opening is provided in the side wall near the terminal end of the machine casing to communicate with the bottom, so that the tank on the starting end side can be replaced with the side wall through this opening. Therefore, if rice husks are mixed in the harvested paddy, if it is passed through a huller, brown rice whose quality has deteriorated due to insufficient drying and mold that has been exfoliated will be mixed into the good brown rice. As the grain ages, the sorting and adjustment work becomes extremely difficult, but now that the rice grains are sorted and removed before being fed to the huller, the quality of the unhulled rice does not deteriorate. Moreover, the tank can also be used as a staking hopper with the simple operation of removing the tank attached to the starting end and supplying the inner circumferential surface of the sorting cylinder and replacing it with the side wall near the end. It could also be used as a grain transporting device, making it extremely convenient and versatile.

In addition, when used as a grain carrying device, the tank may be installed at the bottom near the terminal end, making it easier to load the lifted material into the tank.
