Description

[Detailed description of the invention] The present invention relates to an improvement of a rice hulling sorting device.

Traditional paddy brown rice shake! Since the II sorting device is large-scale, the biggest drawback is that the installation area and volume are large in proportion to the capacity as a rice hulling sorting device, and there is a danger of operating it near the oscillating body, and the oscillation; Because the height of the board is high, the east center of the swinging part is high, which causes large vibrations and many defects such as instability.

The present invention streamlines the arrangement of the hulling device and the oscillating sorting device and the transmission device, and also incorporates the reciprocating oscillating unit inside the safety case, thereby making operation safer than the conventional husking device. The aim is to develop and provide a rice hulling sorting device.

The present invention will be explained with reference to embodiment figures. Figures 1 and 2

This is a rice hulling sorting device in which a swinging sorting device U6 is provided on the upper part of a base 5 on the side and a hulling sorting process is integrally formed.

The hulling chamber 3 is provided with a supply lower on the upper wall, and has an I]i2 f? Tkh for rolls 8 and 9 respectively
A pair of parallel shafts 10.11 are mounted opposite each other, and one of them is formed so as to be able to move near and far with respect to the other shaft, and a pair of grain plates 12.12 are mounted below it for ejection. Lower rice husk I through outlet 13! 1.Contact the diverted drainage gutter,
The wind selection section 14 of the downflow gutter 2 has its negative end connected to the air intake port 16 of the exhaust fan 15, and the other end connected to the outlet window 17.
The rice lifter 18 for paddy rice, which is connected to the bottom of the gutter of the downflow gutter 2, is connected to the rice lifter 19 for mixed grains of paddy and brown rice, and its discharge port 20 is provided in the swing sorting device 6. It is connected to the storage tank 21.

Further, the oscillating sorting device 6 includes a sorting board 22 having a rough surface.
The upper fulcrum provided on the base 5 and the lower fulcrum provided on the base 5 are connected to the support rod 23.
. . . , the force application point of the sorting board 22 and the crankshaft 24 of the eccentric rotation mechanism are connected by a connecting rod 25, and the swinging direction of the sorting board 22 is aligned with the parallel shaft 10 of the rod removing rolls 8, 9. .11, and is mounted so that it can swing up and down diagonally at the swing angle, and it is also sorted! The supply port 26 provided on the supply side of 22 and the discharge port 27 of the tank 21 are connected by a conveying screw conveyor 28, and the mixed grains of paddy and brown rice in the discharge tin 29 provided on the discharge side of the sorting board 22 are passed through a flow tube. to the supply port of the fried rice Ia 19 for mixed grains of unhulled brown rice, and flow the unhulled rice in the discharge gutter 29 to the supply lower of the unhulled rice feeder 3 by the rice lifter 30 for unhulled rice. Brown rice is formed so as to be flowed out of the machine by a rice lifting machine 31 for brown rice, and 32 is a driving type 11 machine installed on the upper wall of the hulling room 3.

Next, the transmission device B will be explained with reference to FIG.

The transmission device B includes the rice hulling device 4 and the swinging bar separate neck 6.
Between A and A, the rotating shafts of each of the above devices are gathered together, and each of the pulleys is connected in relation to each other. That is, a driving electric motor 1ji32 is installed on the upper wall of the hulling room 3, a shaft removing pulley 32A is installed on the main shaft of the electric motor 32, and a flat 11 shaft of the hulling room 3 on the hulling device 4 side is installed. 10. Pulley 10A pivoted on 11
.

11A, each pulley 19A of each rice lifting machine 19.30.31
, 30A, 31A, pulley 15 turned to exhaust fan 15
A and the idler wheel 33 are connected by a belt 34 so that they rotate together, and the crankshaft 2 on the 18ii dynamic sorting device G side
The belt 36 connects the second pulley 24B provided at 4, the pulley 28A of the transporting screw conveyor 28, and the pulley 35A of the feeding roll 35, and the second pulley 30B provided at the paddy rice lifter 30. Pulley 24 A provided on the crankshaft 24
It is formed so that it rotates in conjunction with a belt 37.

In addition, 38 is a transparent window for inspection provided in the box-shaped machine frame 1, and 39 is an opening/closing window provided in the front of the hulling room 3.

With the above configuration, when the raw material paddy is put into the supply lower of the hulling chamber 3 and the device is started, the hulled grains nrl (flow down between the scale rolls 8 and 9 and remain unhulled) The rice husks flow down from the outlet 13 of the grain board 12. At the same time, the mixed grains of paddy/brown rice accumulate in the paddy/brown rice discharge 18 at the bottom of the gutter, and are transferred to the discharge gutter 18.
The paddy brown rice inside is fried by a rice lifter 19 for mixed grains of paddy and brown rice, and is supplied to a flow rate regulating tank 21 in which a rocker 3 is provided at the top of a separate device 6. In addition, the mixed grains of paddy and brown rice in the adjustment tank 21 are transported inward by the conveying screw conveyor 28, flow down from the supply port 26 of the sorting board 22 to the board surface, and are shaken and sorted into paddy, brown rice, and mixed grains of paddy and brown rice. They are separated and discharged to the discharge side 29, respectively.

The paddy in the two discharge FAs 29 is guided to the supply lower of the hulling chamber 3 by the rice lifter 30 for unhulled rice and is re-deweighed. Rice frying machine 1
At the same time, the grains flow down to the supply port 9, and are transported by the rice returning machine 19 to the flow control link 21 in the upper part, and then flow down to the sorting board 22 to be re-sorted, and also to the discharge gutter 29. The brown rice inside is taken out to a container outside the machine by the brown rice frying machine 31 and sent to the next process.

According to claim (2), the transmission devices of the hulling device, the swinging sorting device, and each of the rice lifting machines are arranged between the hulling device and the swinging sorting device. The transmission device can be made compact and simple, and can be operated at high efficiency with a single electric motor.

In claim (3), a screw conveyor is installed horizontally in communication between the supply port of the sorting board and the tank, so that the mixed grains of paddy and brown rice can be mechanically conveyed and fed to obtain a constant B. At the same time, there is an effect that the position of the tank can be lowered as much as possible to make the entire device compact and compact.

In this way, the hulling and sorting device of the present invention has the unhulled rice and brown rice swinging sorting device U installed adjacent to the hulling device in the axial direction, and the transmission devices thereof are housed between the hulling device and the swinging sorting device. Therefore, the entire device can be made compact and small, and the transmission device can be simplified. Also, the swinging part is located at the back of the huller, and the door for opening and closing the huller seedlings is located in the front. In addition, since the swinging part is built into the safety case, inspection inside the rice hulling dormitory is easy.
Moreover, the swinging mechanism is housed inside the machine frame, greatly improving work safety, and since brown rice discharged from a separate plate is taken out into a container using a low rice lifting machine, the sorting plate can be mounted low. The center of gravity of the oscillating body is lowered to prevent vibration of the entire machine due to oscillation, and it has outstanding advantages such as ensuring high-precision sorting at all times and smoothly producing high-quality selected brown rice.
It is the fruit of Qin.
