Description

[Detailed Description of the Invention] Industrial Application Field This invention relates to a rice milling machine.More specifically, the present invention relates to a rice milling machine.
This relates to a rice milling machine that can be operated unmanned.

BACKGROUND OF THE INVENTION A conventional rice milling machine has a milling section installed horizontally in the upper part of the machine body, a grain tank provided above the milling section, and the milling section and the grain tank communicating with each other via a raw material drop gutter.

Problems to be Solved by the Invention In conventional rice milling machines, the milling section is located above the center of the machine, so the opening of the grain tank at the top is located at a considerable distance from the floor. For example, 1100m
m, located at a distance. Therefore, when supplying milled rice (raw materials) to the grain tank, it is necessary to lift the raw materials bag, which is heavy with raw materials, by 1100 mm, which makes the grain feeding operation difficult and requires a lot of effort.

Therefore, this grain feeding work is difficult for elderly people and women who are weak, making the rice polishing machine difficult to use.

In addition, since the white rice discharge port that communicates with the milling part is provided in the lower half of the i-tree, the distance between the white rice discharge port and the floor is less than half the height of the machine, for example, 300+nnl~400m.
m.

Therefore, it is not possible to use a white rice container with a height exceeding half the height of the aircraft, so a small white rice container is used.

However, such a small polished rice container cannot accommodate all of the polished rice produced during the rice milling operations. That lick,
An operator must constantly monitor the amount of white rice stored in the white rice container, and when it is full, replace it with another white rice container.

Therefore, unmanned rice milling work is impossible.

In view of the above circumstances, it is an object of the present invention to make grain feeding work easier.

The purpose of the pond is to eliminate the need to replace the polished rice container during the 1% rice milling process.

Means for Solving the Problems This invention provides a polished rice discharge port provided in the upper part of the machine body; a milling part provided in the lower part of the machine body; a grain tank connected above the milling part; The above-mentioned problem is attempted to be solved by providing a polished rice rising pipe that connects the polished rice outlet of the part.

The raw material bag containing the raw material for 1 is lifted from the floor and the raw material is put into the grain tank.

At this time, since the grain tank is connected to the milling section installed at the bottom of the machine, the lifting height of the raw material bag is lower than when the milling section is installed at the top of the machine, which makes the work easier. Raw materials can be added in an easy-to-handle state.

・Also, since the white rice discharge port is installed at the top of the machine,
Since the distance between the floor and the white rice outlet is longer than when the white rice outlet is located in the lower half of the machine, a tall white rice container that can accommodate a large amount of white rice can be used.

Embodiment An embodiment of the present invention will be described with reference to the attached one-size drawings, in which the same reference numerals have the same names and functions.

A milling part 2 is installed horizontally in the lower part 1a of the machine body 1 of the single-pass rice milling machine, and the milled rice outlet 2a of the milling part 2 is connected to the polished rice rising pipe P through the resistance device 3.

This pipe P is provided with grain feeding means for feeding grain under pressure. As this grain feeding means, a blow nozzle 9 provided on the inlet side of the pipe P is used. This blow nozzle 9 is connected to a blower 11 for blowing up grains in a blower box 10.
It communicates with This grain feeding means is not limited to the above, and for example, a grain feeding screw may be used instead of the blast nozzle.

The outlet of the pipe P is connected to the outlet 4 and the filter 6 of the white rice 17F in the upper part 1b of the fuselage.

The height of the white rice discharge port 4 is, for example, 800 mm to 900 mm.
It is mm.

A grain tank 5 is provided in the upper part 1b of the machine body 1 and communicates with the milling section 2 via a raw material drop gutter 5a.

The polishing section 2 includes a polishing roll 13 and a bran removal wire mesh 14,
This rice bran removing wire mesh 14 is connected to a rice bran suction blower 17 of the fan box 1° via a rice bran falling part 15 and a suction duct 16.

The rice bran suction blower 17 and the grain blowing blower 11 are
Although they are separated by partition walls 10a, they are fixed on the same rotating shaft and connected to the same drive source (main motor) 18.

Therefore, both blowers 11.17 rotate at the same rotational speed. However, both blowers 11.17 may be fixed to different rotating shafts and driven independently of each other. In this way, both blowers 11.17 can be operated at different rotational speeds, so that the rice bran suction force and the grain conveyance force can be freely adjusted.

Next, the operation of this embodiment will be explained.

A white rice container 22 is disposed below the white rice discharge port 4. This container 22 is capable of containing all of the polished rice produced in the rice milling operation twice, and its height is appropriately selected within the height of the polished rice drop opening 4.

A raw material bag (not shown) containing milled rice (raw material) 20 is lifted to the height of the grain tank 5, that is, 700 mm to 800 mm, and the raw material 20 is put into the tank 5. Since the lifting height of the raw material bag at this time is 700 mm to 800 mm, the raw material can be loaded in an extremely easy-to-operate state.

Next, the main motor 18 is driven to rotate the whitening roll 13 and the blower 7.11, and at the same time open the shutter 5b to cause the raw material 20 in the grain tank 5 to fall into the drop gutter 5a.

This fallen raw material 20 enters the milling section 2 and is polished to become polished rice 20a.

The rice bran 2b in the milling section 2 falls from the rice bran removing wire mesh 14 and is sucked into the air-permeable rice bran bag 30 by the pressure wind (suction wind) 17a generated by the rotation of the rice bran suction blower 17.

The rice bran 2a falls into the bag 30 and is stored therein, and the pressurized air 17a is discharged to the outside through the mesh of the rice bran 30.

On the other hand, the white rice 20 discharged from the white rice outlet 2a of the milling part 2
a is generated by the grain blowing blower 11, and the blast nozzle 9
The white rice rises inside the white rice rising pipe P while receiving the pressurized air (blow air) 11a ejected from the white rice container 22 from the white rice discharge port 4.
It falls inside and is stored. As described above, this polished rice container 22 can store all of the polished rice produced in - times of rice milling operations, so there is no need to replace it during the rice milling operations.

On the other hand, the pressurized air 11a passes through the labyrinth portion R from the outlet of the polished rice rising pipe P, is filtered by the filter 6, and is then discharged to the outside of the machine.

The embodiments of this invention are not limited to the above,
If kept, it can also be used in a circulating rice milling machine as shown in Figs. 3 to 5 instead of a circulating rice milling machine.

In this circulation type rice milling machine, polished rice 20a that has been circulated and polished in the grain tank 5 falls into the polished rice rising pipe P when the shutter S is opened, and pressurized air 1 is blown from the blast nozzle 9.
1a, the polished rice rises inside the rising pipe P.

Then, the white rice 20a is transferred from the white rice outlet 4 to the white rice container 22.
In addition, the pressure air 11a is filtered through the filter 6.
is ejected from the machine through the

The rice bran 2b that has fallen into the rice bran falling part 15 is sucked by the suction air 17a of the rice bran suction blower 17 and stored in the air-permeable rice bran bag 30, and the suction air sent into the rice bran bag 30 is is discharged to the outside through the

Effects of the Invention As described above, the rice milling machine according to the present invention has a polished rice discharge port at the top of the machine body, so the polished rice discharge port is located at a higher position than that of the conventional example. A container can be used. Therefore, for example, 30 kg to 6
Even when milling 0 kg of raw material, a milled rice container that can store all of the milled rice can be used, so there is no need to replace the milled rice container during rice milling, and unmanned operation is possible.

In addition, since a milling section is provided at the bottom of the machine and a grain tank is connected above it, the height of the grain tank is lower than in the conventional example, so the lifting height of the raw material bag is lowered, for example, 700mm.
The length can be approximately 800 mm to 800 mm.

Therefore, the rice milling machine is easy to handle even for elderly people and women who are weak because the raw material supply operation can be easily performed.
