Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an improvement in an automatic supply amount adjustment device for a rice hulling sorting device.

Conventional rice hulling and sorting equipment has a rice husk wind sorting chamber inside a machine frame on which a huller and a swinging sorter are mounted, and an elevator with an adjustment tank suspended on one side of the machine frame. Since the grains were supplied from the adjustment tank to the equalizer mounted on the top of the sorting plate, the height of the whole device was increased corresponding to the height of the suspended adjustment tank, and the height of the hulling and sorting device was increased. It is inconvenient to transport, has the defect that its installation location is limited, and the distance between the adjustment tank and the flow rate control valve of the hulling device becomes long, making the interlocking problems complicated, and its operation difficult. This method has disadvantages such as a time error.

In view of the above points, the present invention provides a paddy supply hopper for the hulling chamber on the upper part of the machine frame in which the hulling chamber and the rice husk sorting chamber are installed,
An adjustment grain tank is provided on the side of the hopper so as to be movable up and down, and a grain feeding equalizer of the swing sorter is provided below the discharge port of the tank. The grain lifting distance between the grain tank and the mixed grain take-out trough of the rice husk winding room and the communication distance between the grain tank and the flow rate control valve of the hulling room are shortened as much as possible, thereby increasing the machine height. The aim is to develop and provide a high-performance device that improves m-section accuracy by reducing the amount of water as much as possible and downsizing the entire device, and by simplifying the interlocking mechanism of the flow control valve of the hulling device. .

The present invention will be explained with reference to embodiment figures. A pair of VAl! i! A rocking sorter is provided with a hulling chamber 6 in which rolls 4 and 5 are stacked opposite each other and housed integrally inside a machine frame 7, and a sorting board 8 and a rocking device 9 are provided on one side of the machine frame 7. This is a rice hulling sorting device equipped with 10.

In the hulling chamber 6, the raw material paddy flowing down from the paddy supply hopper 11 provided at the upper part of the machine frame 7 flows down between a pair of dehulling rolls 4 and 5 in the chamber 6, and rotates inside each other. The rice is dehulled by the contact friction force of the dehulling rolls, and the dehulled material flows down from the lower discharge port 12 into the chaff sorting air passage 1, where it is sucked by the exhaust fan 2 connected to the sorting air passage 1. The rice husks that are wind-selected by force are removed from the machine through the exhaust pipe 13, and the lightweight immature grains are transferred to the immature grain receiving trough 14, and the heavy mixed grains of paddy and brown rice are transferred to the mixed grain receiving and receiving trough 14. They are formed so as to collect in the gutter 15 respectively.

The mixed grains of paddy and brown rice collected in the mixed grain removal receiving trough 15 are as follows:
It is supplied to the sorting board 8 of the swinging sorter 10 via an automatic supply amount adjustment device which will be described later. The mixed grains are separated and sorted into paddy, paddy/brown rice mixed grains, and brown rice by the oscillating sorting action of the sorting board 8, and the paddy is returned to the paddy supply hopper 11 where it is re-weighed, and the paddy/brown rice is mixed. The grains are paddy and brown rice taken out from the receiving trough 15.
The brown rice is returned to the machine and re-sorted, and the brown rice is taken out of the machine by the brown rice lifting machine 16 and sent to the next process.

The feed layer automatic adjustment device of the present invention has a III selection device 17 consisting of a cross air passage and an adjustment grain tank 18 which are arranged in relation to the side of the paddy supply hopper 11 provided on the upper part of the machine frame 7. , the air selection device 17 has a box frame 1 containing the air passage.
The upper side of the box frame 19 is pivoted to a support shaft 20 so as to move up and down, and the other side of the box frame 19 is suspended by an elastic spring 21, and the lower side of the grain outlet 22 of the wind sorting device @17 is A grain tank 18 for adjustment is provided in the box frame 19, and [iS'lW
The grain feeding port 23 provided on the upper side of the box frame 19 and the mixed grain receiving trough 15 provided in the rice husk sorting chamber 3 are connected to the mixed grain lifting machine 2.
4, and connect the exhaust port 25 of the wind selection @17 to the m pipe 2.
6 is connected to the air supply port of the exhaust fan 2, and the swing sorting valve is connected to the air supply port 27 of the adjustment grain tank 18 by the
In addition to disposing ten grain equalizers 28, the guide rod 29 provided on the box frame 17 and the operating rod 31 of the flow control valve 30 provided on the paddy supply hopper 11 are connected to The flow control valve 30 is configured to open and close in conjunction with changes in vertical movement. 32 is the discharge amount of the grain tank for adjustment! The discharge control valve 33 is a feed roll provided at the discharge portion of the paddy supply hopper 11.

With the above-mentioned configuration, the mixed grains of paddy and brown rice collected in the paddy brown rice take-out receiving trough 15 of the rice husk wind sorting room 3 by the wind sorting action of the rice husk wind sorting room 3 are transferred to the mixed grain fried grains connected to the receiving trough 15. The grain is fried by the machine 24 into the wind sorting device 17 in the upper part. In this grain-lifting action, some of the paddy inside the mixed grains is dehulled by the impact force, but the mixed grains are sucked into the grain feeding port 23 of the box frame 19, and the chaff is sucked up and removed from the machine. . In addition, the wind-selected mixed grains of paddy and brown rice flow down from the grain flow port 22 of the wind-selecting device 17 and accumulate in the adjustment grain tank 18, and some of the mixed grains are fed through the opening of the discharge control valve 32. It flows out into the equalizer 28.

Inside the equalizer 28, a predetermined amount of mixed grains of paddy and brown rice is constantly conveyed by the vibration force and supplied to each sorting board 8. On the other hand, in the adjustment grain tank 18 whose discharge is controlled, the remaining mixed grains gradually increase, and as the residual grains increase, the elastic spring 21 gradually expands and the box frame 19 is supported. axis 20
It will move downwards centered on . As the box frame 19 moves downward, the guide rod 29 fixed to the wall pushes down the operating rod 31 to appropriately open the opening of the flow rate control valve 30, so that this moderate flow rate g! By closing the control valve 30, the hulling chamber 6 is cleared.
The amount of raw material paddy supplied to the grain tanks 4 and 5 is gradually restricted, and the remaining mixed grains in the grain tank 18 are always maintained at an adequate level, and the supply of paddy and brown rice mixed grains to each sorting board 8 is stable. Therefore, it is possible to reliably perform an efficient sorting operation continuously.

Claim (3) provides that the adjustment grain tank 18A (see FIG. 4) is separated from the others by mounting a private selection device 17A connected to the exhaust fan provided in the rice husk wind selection room. Since it is formed on the body, it has the effect of simplifying the manufacturing, processing, and installation of the device.

As described above, the automatic supply amount adjustment device of the hulling and sorting device of the present invention is capable of adjusting the grain lifting distance between the grain adjustment tank and the mixed grain take-out trough in the rice husk wind sorting room, and the flow rate adjustment between the grain adjustment tank and the hulling room. Since the communication distance of the valve is shortened as much as possible, the height of the machine can be lowered as much as possible, making the entire device more compact, and the interlocking mechanism of the flow control valve of the rice hulling device has been simplified to improve adjustment accuracy. It is intended to reduce the effects of being able to do so.
