Description

[Detailed description of the invention] The present invention relates to improvements in rice hulling sorting equipment.

In the conventional paddy/brown rice oscillating sorting device, a grain tank is suspended from the discharge port of an elevator installed on one side of the hulling device, and the mixed grains of paddy/brown rice stored in the tank are supplied to the oscillating sorting device. The biggest flaw was that the area and volume of the structure were large in proportion to the capacity, and the oak for controlling the grain flow process was large and located at a high position, so we had to inspect it.

It also had drawbacks such as difficulty in adjustment work.

In order to solve the above-mentioned drawbacks, the present invention includes a rice lifting machine for mixed grains consisting of a thrower installed at the discharge port of the mixed grains of paddy and brown rice in the draining gutter of the hulling device, Bend the tray and extend it over the sorting board of the swinging sorting device, and connect the mixed grain dosage tank to the discharge port of the rice lifting device so as to be vertically movable;
connecting the outlet of the hanging tank to the supply section of the sorting board;
By connecting the hanging tank and the supply valve of the hulling device with a connecting member such as a wire, the amount of grain fed to the hulling device can be adjusted according to the increase or decrease in the amount of rice in the hanging tank, and the grain flow rate can be adjusted. A hanging tank is installed in the space above the sorting board to reduce the volume of the entire device as much as possible, and the machine height is lowered to simplify inspection and adjustment of the adjustment mechanism. Therefore, it is our intention to develop and provide a small-scale, high-performance Ya sliding sorting device.

The present invention will be explained with reference to embodiment figures. Reference numeral 1 denotes a box-shaped machine frame, and inside the machine frame 1 there is a rice husk wind sorting drainage trough 2 on one side.
A hulling and sorting device is equipped with a hulling device 4 equipped with a hulling chamber 3 on the top of the hull, and a swinging sorting device 6 on the top of a base 5 on the other side to form a hulling and sorting process integrally. be. In the hulling room 3, a supply hopper 8 equipped with a supply valve 7 is provided on the earthen wall, and one NcPJ roll 9.10 is installed inside the hopper 8.
Parallel of S.J! 11111.12, and one of them is formed so that it can be moved near and far with respect to the opposite axis, and the screening air passage 13 above the downflow gutter 2 provided below is connected to the exhaust fan 14. A rice lifter 16 for mixed grains is attached to the discharge port 15 for the mixed grains of paddy and brown rice flowing down from the flow 12, and the swinging sorting device 6 is connected to a swinging device mounted on the base 5. A sorting board 18 is mounted on the top of the sorting board 17 so that the board 8 can be swung diagonally up and down, and mixed grains of paddy and brown rice are supplied from the supply section 19 of the sorting board 18 and phase-wise sorted on the board surface. , A discharge ring 20iC provided on the discharge side is formed so as to separate the grains into three types: unpolished rice, mixed grains of unhulled brown rice, and paddy, and discharge them. Then, the rice lifting tray 2'1 of the rice lifting machine 16 for mixed grains provided in the paddy (3 device 4) is bent and extended onto the sorting plate 18 of the swing sorting device 6, and the front delivery pipe 21 outlet part 2
2, a hanging tank 23 for agglomerated grains is connected vertically movably, and the outlet 24 of the hanging tank 23 is connected to the supply section 19 of the sorting board 18, so that changes in the amount of grain in the hanging tank 23 can be controlled. The hanging tank 23 and the supply valve 7 of the hulling chamber 3 are connected by a connecting member 25 such as a wire so that the grain feeding in the hulling chamber 3 can be adjusted according to the situation. Claim (2) provides that the mixed grain dosage tank 23 is suspended by a suspension device @26 fixed to the discharge port 22 of the rice lifting device 21, and outlet section 22 of
and the grain feeding port 27 of the hanging tank 23 are connected by a flexible advance pipe 28, and 29 connects the rod end of the hanging device 26 and the hanging tank 2.
3 is an elastic spring connecting 3, 30 is a wire fastener, 31
3 is a fulcrum shaft to which the hanging tank 23 is fixed; 32 is a fixture for fixing the wire tube; and 33 is a fixture for the rice lifting station 21.

With the above configuration, when raw material paddy is put into the supply hopper 8 of the hulling chamber 3 and the device is started, the paddy flows down between the dehulling rolls 9 and 10 through the open supply valve 7 and is dehulled. While the culled material flows down to the rice husk air sorting down-flow trough 2, the mixed rice husks are air-sorted in the sorting air passage 13 and sent to the exhaust fan 1.
The mixed grains of paddy and brown rice that have been discharged outside the machine through 4 are lifted by a mixed grain lifting R16 provided at the discharge port 15, and are sent into a hanging tank 23 via a rice lifting conveyor 21. While being accumulated and stored, the mixed grains gradually flow down from the discharge port 24 and are supplied to the surface of the sorting plate 18 via the supply part 19 of the sorting plate 18, and are pressed out by the rocking movement of the plate 'i8. It is sorted and separated into brown rice, mixed grains of paddy/brown rice, and paddy. During that time, as the amount of mixed grains of paddy and brown rice stored in the storage tank 23 increases, the hanging tank 23 becomes suspended due to its weight.
It descends forward in a rolling manner around the fulcrum shaft 31 of No. 26. The hanging tank 23's transfer letter descent ζ, 2,: Stiff・'l
Connecting fili material 25 fixed to the fastener 30 of the sink 3
The wire extends downwardly, and the operating rod 7A of the supply valve 7 connected to the other end of the wire is pulled up, the opening of the valve 7 gradually closes, and the wire is moved from the suspension tank 23 to a predetermined position. When the pressure drops to this level, the supply valve 7 completely closes its opening and the supply of paddy to the hulling chamber 3 is stopped. Further, when the amount of grain in the hanging tank 23 decreases and the tank is lifted upward by the elastic force of the elastic spring 29, the wire of the connecting member 25 is pushed up by the action, and the operating rod 7A connected to the other end side is pressed down to open the supply valve 7, and the paddy is supplied to the hulling chamber 3 through the opening, and the hulling action is immediately started, and the mixed grains of paddy and brown rice are transferred to the hanging tank 23 again. Since the mixed grains at the opening are always stored in the hanging tank 23, the hulling and sorting action can be carried out smoothly.

As described above, the hulling and sorting device of the present invention can rationalize and smooth the grain flow by adjusting the grain feeding port of the hulling device according to changes in the amount of grain in the hanging tank, and can also streamline and smooth the grain flow. By mounting a hanging tank in the space above the panel, the volume of the entire device can be made as small as possible, and the height of the machine can be lowered to simplify inspection and adjustment of the adjustment mechanism, making it small and highly efficient. This method has the advantage of being able to mass-produce high-quality selected brown rice by carrying out a thorough hulling process.

According to claim (3), since the bottom wall surface of the bent extension part of the hanging tank and the homa rice advancing pipe is formed into an inclined surface having an angle of repose of grains or more, the grains are not fried. The mixed grains of paddy and brown rice flow smoothly down each bottom wall surface in an accelerated manner to facilitate the accumulation of grains in the hanging tank, and because the grains are discharged by flowing down each bottom wall surface, residual grains are eliminated. It has the effect of preventing damage caused by particles.
