Description

[Detailed Description of the Invention] (Field of Industrial Application) The present invention relates to a grain feeding device for a rice milling machine.

(Prior Art) The supply section of a conventional rice milling machine has a structure in which a supply hopper is connected to a supply cylinder, and the grains supplied to the hopper flow into the hopper by their own weight.

(Problems to be Solved by the Invention) In order to allow the fed grain to flow into the feed hopper under its own weight, a minimum slope is required at the outlet of the feed hopper, so that the hopper is made small. Also, because the slope is minimal, a small blockage may expand to the point where no flow occurs at all.

(Means for Solving the Problem) Therefore, the present invention provides a blower 24 for blast rice at a position near the blast rice milling device, and connects the blower 24 for blast rice and the blast polishing roll 4 of the rice polishing device. In the case connected by a blast pipe 16, an air blowing part 3 that blows out toward the lower end opening 19 of the supply hopper 18 of the blast whitening device is located near the lower end opening 19.
4 is provided, and the air blowing part 34 and the blower 24 for blowing air are provided.
As a grain feeding device for a rice milling machine, which is connected with the air blowing pipe 35, the air blowing section 34
This eliminates clogging with more pressure.

(Example) An example of the present invention will be described with reference to the drawings.
is the vertical rotation axis, and the passive pulley 2 is attached to the lower end.
An upward feeding grain feeding spiral 3 and a blast whitening roll 4 are attached to the outer periphery of the vertical rotating shaft 1. Reference numeral 5 denotes a grain feeding tube that surrounds the outer periphery of the upward feeding grain feeding spiral 3, and 6 represents a whitening roll that surrounds the outer periphery of the blast whitening roll 4.

A supply port 7 and a residual rice removal port 8 are opened at the lower part of the grain feeding cylinder 5. Reference numeral 9 denotes a tensioning hopper attached to the outside of the supply port 7. An upper case 10 is provided on the upper part of the polishing tube 6, and the upper end of the polishing tube 6 and the lower surface of the upper case 10 are joined. 11 is a discharge port provided on the side of the upper case 10; 12 is a resistance lid;
13 is the adjustment knob, 14 is the resistance lid 12 and the discharge port 1.
It is a spring that causes the bullet to land on 1.

The vertical rotation shaft 1 is formed of a hollow pipe, and the upper end 15 thereof is directly or indirectly connected to a blower pipe 1.
The tips of No. 6 are connected. The rice polishing device is entirely or partially surrounded by a box-shaped case 17. Reference numeral 18 denotes a supply hopper, and the bottom of the supply hopper 18 has a gentle slope, and the lower end opening 19 of the supply hopper 18 faces above the filling hopper 9.

A motor 21 is fixed to the lower space 20 of the supply hopper 18. The drive shaft of the motor 21 projects upward and downward to form an upper drive shaft 22 and a lower drive shaft 23.

A blower 24 for blowing air is fixed to the lower drive shaft 23, and the blower pipe 16 for blowing air is connected to the outlet of the blower for blowing air 24. A drive pulley 25 is fixed to the lower drive shaft 23, and a belt 26 is passed between the driven pulley 2 and the drive pulley 25.

A suction blower 27 is fixed to the upper drive shaft 22, and the suction port 28 of the suction blower 27 and the bran chamber 29 formed on the outer periphery of the polishing tube 6 are connected to the suction tube 30.
Connect with. 31 is an exhaust pipe, which is connected to a pipe 33 leading to the cyclone.

Note that it is possible to use only one of the upper drive shaft 22 and the lower drive shaft 23 and to attach the blower 24 and the suction blower 27 coaxially. It can also be applied to horizontal rice milling machines.

The lower end opening 19 of the supply hopper 18 includes:
Air blowing section 34 that blows air toward the lower end opening 19
The air blowing section 34 and the blower 24 are connected by a blowing pipe 35.

The metering tank 36 is provided below the discharge port 11 , an on-off valve 37 is attached to the lower end of the metering tank 36 , and a metering container 38 is provided below the on-off valve 37 . 39 is a foot-operated operation body.

(effect) Next, we will discuss the effect.

When brown rice is supplied into the supply hopper 18 and fed to the supply port 7 from the lower end opening 19 through the loading hopper 9, the grain feeding cylinder 5 is raised by the upward grain feeding spiral 3, and the grain is spouted in the polishing cylinder 6. The rice is stirred and polished by the wind whitening rolls 4, taken out from the discharge port 11 of the upper case 10, weighed in the measuring tank 36, and taken out into the container 38 by operating the foot-operated operating body 39.

During that time, the wind blown out from the blower 24 fixed to the lower drive shaft 23 of the motor 21 flows through the blower pipe 16 from the upper end 15 of the rice milling roll 4, and the blower blows out the rice milling roll 4. It is blown out from the hole 32, and the adhering rice bran polished by the blast rice polishing roll 4 is blown away from the blow hole 32, and is ejected into the rice bran chamber 29 through the holes of the polishing tube 6.

Since the end of the suction pipe 30 connected to the suction port 28 of the suction blower 27 fixed to the upper drive shaft 22 is open in the rice bran chamber 29, all the dust is sucked out and the exhaust pipe 31 to the outside of the aircraft.

During the above operation, in the present invention, the blower pipe 35 is attached to the blower 24, and the air blowing part 34 connected to the blower pipe 35 is connected to the lower end opening 19.
Since the hopper is structured to blow air toward the grains, when the supply hopper 18 is full of grains, it does not blow the air powerfully due to the grains, but when there is less grain, Powerfully blows air to prevent clogging.

(Effects) The supply section of the conventional rice milling machine has a structure in which a supply hopper is connected to a supply tube, and the grains supplied to the hopper flow into the hopper by their own weight.

In order for the fed grain to flow into the feed hopper under its own weight, a minimum slope is required at the outlet of the feed hopper, thus making the hopper small. Also, because the slope is minimal, a small blockage may expand to the point where no flow occurs at all.

However, in the present invention, a blast blower 24 is provided in the vicinity of the blast rice polishing device, and the blast blower 24 and the blast whitening roll 4 of the blast rice polishing device are connected by a blast blast pipe 16. In this case, an air blowing part 34 that blows out toward the lower end opening 19 of the supply hopper 18 of the blast whitening device is provided at a position near the lower end opening 19, and the air blowing part 34 and the blower 2
4 is connected to the grain feeder for the rice milling machine by the blast pipe 35, so even if the gradient of the feeding hopper 18 is minimal and the flow is poor, the pressure from the air blowing part 34 is effective in eliminating clogging, and it is similar to coin milling. It is extremely effective when used as an unmanned device.
