Description

[Detailed description of the invention] This invention uses a cylindrical sorter to sort out and remove rice husks mixed in with the paddy, and also has a cylindrical sorter installed inside a rotatably horizontal sorting cylinder so that it can also be used as a grain carrying device. Separately from the supply port through which paddy flows in, a drop port is provided at the bottom of the slanted bottom plate that leads to a falling channel that communicates with the cross-feeding path that conveys normal paddy leaking from the sorting tube. A switching valve is pivotally mounted at the branching part from the mouth so that it can be fanned using the lower end as a fulcrum, and as desired, by operating the switching valve, the grains in the supply tank can be flowed into the sorting cylinder or directly into the cross-feeding route. It is possible to drop the grain or select one of them and use it as a sorting machine or as a grain carrying device.

To give an overview of the motive behind devising this invention, in the first place, in the case of paddy rice, mold grows on the ears of rice, which can turn yellow in places depending on the climatic conditions such as humidity and temperature of the year from the time of heading. Occur. 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, etc. in a field where such rice husks have been generated, the rice koji husks will be mixed into the raw rice, and even if they are dried, they will not be dried because of the mold attached to them. 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, when the paddy is not mixed with rice husks, a grain carrying device is used to lift the paddy to the dehulling section and supplied, and when the paddy is mixed with rice koji, a sorting machine is used to remove the paddy. By removing the koji paddy and hulling the normal paddy, even if it is from a field where the koji paddy was produced, brown rice with good quality and sorting can be obtained. It is convenient to try to use.

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

First, we will first describe the sorting machine used when the rice husk is mixed in.

By attaching the head 12a, the head 12a receives a pressing force and is fixed. 14 is an annular guide plate fixed to the inside of the machine wall 13 concentrically with the support shaft 12,
The lower part of the inner circumferential surface becomes the inflow path 14a. 15 is an opening bored in the machine wall 13 above the fixed lower end of the guide plate 14; 16 is a tank with telescopic legs 16a;
A supply port 16c and a drop port 16e are provided at the bottom of the oblique bottom plate 16d. And this supply port 1
The bottom end is the fulcrum P at the branching point between 6c and the drop port 16c.
A switching valve A that can be fanned is pivotally mounted, and the operating lever
When the switching valve A is in the upright position due to the rotation of Aa, the supply port 16c is closed and the drop port 16e is opened, and when the switching valve A is in the collapsed position, the supply port 16c is opened and the drop port 16e is closed. There is.

The supply port 16c can be inserted into the opening 15 described above, and when the supply tank 16 is attached, the inflow path 1
It communicates with the inside of the sorting cylinder 6 via 4a.

Reference numeral 4a denotes a falling channel projecting obliquely upward from the higher side
6 is positioned directly below the drop port 16e, and the drop port 16e is configured to communicate with the transverse feed path 4 via the drop channel 4a. Note that 17 is a butterfly bolt for attaching the supply tank 16.

Reference numeral 18 denotes a rotating shaft that is supported by the machine wall on the lower side 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;

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 high side X to the low side Y. , 22 is the lower side Y
1a is a transmission part that rotates the rotating shaft 18 from the intermediate shaft 21; 23 is an outlet for taking out the rice koji that has not leaked from the circumferential surface of the sorting tube 6;
is a cover that covers the upper open part of the machine case 1.

Therefore, when rice koji is mixed in normal paddy, the rice koji can be processed using a cylindrical sorter with the switching valve A in the down position shown by the solid line in FIG. The paddy is removed and only normal paddy is supplied to the huller through the lifting path 5. That is, the paddy mixed with the rice koji put into the tank 16 is sequentially supplied to the inner circumferential surface of the high side The normal paddy, which has a size of The rice koji that did not leak out from the sorting hole 7 of the sorting tube 6 moves inside the sorting tube 6 to the lower side Y and falls from the end, and is taken out from the outlet 23.
It is taken out from the machine casing 1.

Next, if there is no rice koji or paddy mixed in, and there is only normal paddy, it is used as a grain carrying device and immediately supplied to the huller. If the posture is rotated in the direction of the arrow in FIG. 1 and switched to the standing posture shown by the imaginary line, the drop port 16e will open, the supply port 16c will close, and the inside of the supply tank 16 will flow from the drop flow path 4a to the cross feed path 4. It is directly connected to the grain transporting device, and the normal paddy in the supply tank 16 is immediately supplied to the hulling machine via the transverse path 4 and the lifting path 5.

As described above, the present invention is to horizontally suspend a sorting tube with a large number of sorting holes on its circumferential surface in a rotatable manner with the starting end on the high side and the end on the low side. A supply tank is provided on the high side so that it can be attached freely, and a cross-feeding path is provided horizontally at the bottom of the machine casing from the high side to the low side, and the sorting hole is of a size that allows normal paddy to pass through. At the same time, a supply port is provided at the lower side wall of the supply tank that leads to the inflow path communicating with the inside of the sorting cylinder, and a drop port that communicates with the falling flow path that communicates with the traversal path is provided at the lower part of the slanted bottom plate of the supply tank. A switching valve is pivotally connected to the branching part between the supply port and the drop port so that it can be fanned using the lower end as a fulcrum, and when the switching valve is in an upright position, the lower part of the supply tank is moved horizontally through the drop port. Since it is configured so that it can be switched and communicated with the starting end of the sorting tube through the supply port when it is in the lying position, it is possible to sort out and remove the rice koji mixed in with the paddy, and to transport it. By switching the switching valve, it became possible to use it as a grain transporting device, making it extremely convenient and versatile. In particular, if the harvested paddy contains rice husks, if it is passed through a huller, brown rice whose quality has deteriorated due to insufficient drying and mold that has been exfoliated may be mixed into the good brown rice. As the grain ages, the sorting and adjustment work becomes extremely difficult, but since the rice husks are sorted and removed before being supplied to the huller, the quality of the unhulled rice does not deteriorate. It is.
