Description

[Detailed Description of the Invention] The present invention relates to a grain frying and sorting machine that separates fine grains such as immature grains and crushed grains while frying grains such as rice.

This type of lifting and sorting machine has already been disclosed in Japanese Patent Application Laid-Open Nos. 58-14976, 58-27676, and 58-27677. As shown in FIG. 1, these lifting and sorting machines are made up of a rotatable sorting net 1 and a grain lifting spiral 2 that is fitted inside the sorting net 1 and is concentrically arranged so as to be counter-rotatable, and both of them are connected to the outer grain body 3.
The grain lifting spiral 2 is provided with a spiral blade 2b on the outer periphery of a hollow shaft 2a, and is supported on the surface 4a inside the lower tube 4 via a bearing 5 in a state where it is not in contact with the surface 4a (i.e., there is a gap).

The area of the spiral blade 2b that faces the lower cylinder 4 is the supply area 6, the area that opposes the mesh 1a is the sorting area 7, and the area that faces the upper cylinder 1b of the mesh 1a is the action area 8. It is structured separately. Further, the grain lifting spiral body 2 has a rotating shaft 9 at the lower end connected to a drive motor 11 via a pulley 10.
The grain frying spiral body 2 is rotated at about 300 rpm, and the sorting net body 1 is rotated in the opposite direction at about 75 rpm.

Therefore, when grains are supplied from the supply port 12, they fall into the lower cylinder 4 and fill it. The filled grains are fried upward by a spiral blade 26 in the supply area 6 and fed to the sorting area 7. In sorting area 7,
Mesh 1 of sorting net body 1 that reversely rotates supplied grains
Fine grains such as immature grains and broken rice pass through the mesh 1a, are sieved out of the sorting mesh 1, and are discharged from the discharge port 13 to the outside of the machine.

On the other hand, the grains remaining in the sorting net 1 are gradually fried and reach the take-out area 8, where the grains are fried to the top and taken out from the take-out port 14. The grains thus sorted and taken out are weighed with a scale, bagged, packaged, and delivered.

However, according to the above fried grain sorting machine,
Filled grains in the supply area 6 (frying would be extremely difficult if the grains are not filled) pass through the gap in the hollow shaft 2a of the spiral body 2 (the hollow shaft is used to reduce the weight of the shaft). There was a drawback that the rice would get stuck in the rice, break up inside it, and become crushed due to the rotation of the spiral body 2, causing it to rot.

In view of the above-mentioned circumstances, the present invention provides a U-shaped cylinder 16 disposed within the hollow shaft 2a with a slight gap 15 between it and the inner surface 2c of the hollow shaft via a packing 15a. 16 is provided with an outlet 16a for discharging grains.

The contents of the present invention based on the above configuration will be explained with reference to the drawings of the embodiments. The fried grain sorting machine according to the present invention has many parts in common with the fried grain sorting machine shown in FIG. 1, and the common parts are given the same figure numbers.

As shown in FIGS. 2 and 3, the present invention is shown in FIG. It has the same structure and function as conventional fried grain sorting machines. However, between the fried grain sorting machine according to the present invention and the conventional fried grain sorting machine, the holding and rotating structure of the fried grain spiral 2 and the rotating structure of the sorting net 1 are completely different.

That is, the U-shaped cylinder 1 supported on the frame 17
6, a helical body holding/rotating shaft 19 and a sorting net rotation shaft 20 are coaxially supported in an integrated state via a U-shaped bearing 18, and the sorting net rotation shaft 20 is At the upper part, the engaging part 1c of the sorting net 1
The rotating shaft 20a that is engaged and held is engaged and fixed.
An upper support 21 is fixed to the upper part of the hollow shaft 2a, and a lower support 22 is fixed to the lower part of the hollow shaft 2a. In order to rotate the grain frying spiral body 2, first, the engaging portion 22a provided at the center of the lower support body 22 is rotated.
The rotating shaft 20a is fitted therethrough, and the spiral body 2 is lowered. Then, the fitting part (bearing) 21a provided at the center of the upper support body 21 and the upper part of the rotating shaft 20a are tightly fitted, and the engaging part 22a is placed on and engaged with the helical body holding/rotating shaft 19. do. Next, the sorting net 1 is placed over the spiral body 2 and lowered to touch the cylinder 23 through the packing 23a. Note that the lower part of the sorting net 1 is held by centering rollers 24 fixed at three positions on the sides of the cylindrical body 23. Further, as described above, the rotating shafts 20, 20a are configured to center and support the upper part of the spiral body 2, and also to center, support, and engage the sorting net 1. Note that 5 is a motor for rotating the rotating shafts 19 and 20, 26 is a transmission (this transmission may be a gear type or a pulley type), 27
The grains discharged from the discharge port 16a are transferred to the motor 25.
This is a protective umbrella to prevent people from entering inside.

In the fried grain sorting device configured in this way,
First, when the motor 25 is turned on, the helical rotating shaft 19 and the sorting net rotating shaft 20 rotate at different rotational speeds via the transmission 26. When grains are supplied from the supply port 12, the grains fill the supply area 6, rise under the action of the spiral blades 26, and are sieved into sized and fine grains in the sorting area 7, and the sized grains are taken out. It passes through the outlet 14 from the area 8 and is taken out. On the other hand, the fine particles are discharged from the discharge port 13. At this time, in the supply area 6, there are grains that rise to the sorting area 7 due to the rotation of the spiral blade 26, and grains that try to pass through the gap 15 and push into the hollow shaft 2a. Some of the grains that try to push into the hollow shaft 2a cannot be pushed in because the wall of the U-shaped cylinder 16 becomes an obstacle, but some of the grains end up inside the U-shaped cylinder 16. All of the grains that have entered the cylinder in this manner are discharged to the outside (downward) from the discharge port 16a. Also, due to heart fluctuation etc., the gap 1
Even if the shaft 5 has a large gap and a large amount of grains enter, since the U-shaped bearing 18 is used, grains will not enter the bearing 18, and the bearing 18 and the rotating shaft 1
9, 20 will not be damaged. In addition, U-shaped cylinder 1
6 may be inclined as shown in FIG. 4 to speed up the discharge of grains.

As is clear from the above explanation, according to the present invention, grains are less likely to be forced into the hollow part of the grain frying spiral, and the grains that have entered can be easily discharged, so there is no risk of spoilage etc. It has the effect of
