Description

[Detailed description of the invention] The present invention relates to a safety device for a rice huller sorting machine.

In conventional hulling and sorting machines, when the swing sorting device is stopped, the motor is stopped and the entire hulling and sorting machine is stopped, so all grain lifting machines are stopped and grains remain inside the machine. When the grain lifting machine became clogged and restarted, there was a concern that the thrower blades would be damaged by the accumulated grains, causing an accident.

To avoid this, it is best to stop the supply of grain to the huller and sorter, operate the machine for a while, and then stop the machine when no grain is being discharged. Since the machine operates unnecessarily, energy loss increases.

An object of the present invention is to solve the above-mentioned drawbacks, to have a simple structure, to keep the necessary grain lifting machine in operation even when only the oscillating sorter is stopped, to minimize energy consumption, and to produce grain inside the machine. To provide a safety device for a rice hulling sorting machine which prevents clogging of the grain lifting machine and damage and damage to the blades of the thrower by discharging all the grains, and eliminates the fear of accidents when restarting.

Embodiments of the present invention will be described in detail based on the drawings.

In FIG. 1, the grains inputted from the piling tank 1 are hulled by the rubber rolls 28 in the hulling chamber 27, and the mixed grains of brown rice and paddy are processed by the mixed grain lifting machine 4.
An oscillating sorting device 10 having a plurality of sorting plates 11 at the bottom of a mixed grain discharge pipe 2 sent upward by a
The liquid is fed into an equalizer 3 which is fixed integrally with the liquid. Then, the grains to be discharged from the mixed grain discharge pipe 2 are put into the discharge tank 5 provided at the bottom of the equalizer 3, and as shown in FIG. 21, and the switching arm 22 integrated with the opening/closing bottom plate 21 is suspended by a fitting 23 integrated with the equalizer 3 and a spring 24. and,
A spring 24 causes the switching arm 22 to actuate to either direction instantly when it exceeds the dead center of its rotation range. Moreover, the grains put into the discharge tank 5 are discharged outside the machine.

The switching arm 22 is connected via an operating wire 25 to a mounting body 20 mounted on the tensioner arm 6, which serves as an operating device for the swing sorting device 10, and the outer cylinder of the operating wire 25 is mounted on the machine body. It is held by a plurality of supports 26. tension wheel arm 6
is fixed to one end of the shaft 15, and a handle 16 is fixed to the other end of the shaft 15, and the handle 16 has an arc-shaped guiding groove 17 attached to the side of the machine opposite to the side of the machine where the tension wheel arm 6 is provided. Information board 1 with
8, it is guided by a pin 19 so as to be able to freely move in an arc. In addition, the pulley of the tensioner arm 6 is a belt 7 that is stretched around the drive pulley 8 and the crankshaft pulley 29.
hang it up. A prime mover 13 is placed on a prime mover installation stand 12 installed on the top of the hulling device 30 , and when the prime mover 13 is driven, the prime mover pulley 31 is moved through a belt 33 stretched by a pulley of a tension wheel arm 32 . The blower pulley 34 and the tensioning wheels of the two rubber rolls 28 are operated, and the driving pulley integrated with the shaft of the rubber roll 28 is connected to the immature grain screw via the belt 36 stretched by the pulley of the tensioning pulley arm 35. Shaft pulley 3
7, and the driving pulley 8 operates the crankshaft pulley 29 via the belt 7 stretched by the pulley of the tensioner arm 6, which is the actuator of the swing sorting device 10. 9 causes the swing sorting device 10 to swing.

To explain the operation of the embodiment of the present invention, in FIG. 2, the handle 16 is normally in the B position.
The opening/closing bottom plate 21 of the equalizer 3 is closed. The belt 7, which is stretched around the driving pulley 8 and the crankshaft pulley 29, is stretched by the pulley of the tensioning pulley arm 6, and the swing sorting device 10 is driven.

When the handle 16 is operated to the A position, the tensioner arm 6 is operated via the shaft 15 in the direction of loosening the tension on the belt 7, thereby stopping the transmission of the belt 7 from the driving pulley 8 transmitted from the prime mover 31, In order to stop the rotation of the crankshaft 9, the operation of the oscillating sorting device 10 is stopped, and at the same time, the operating wire 25 is pulled to connect the opening/closing bottom plate 21 of the equalizer 3 via the switching arm 22.
The grains discharged from the mixed grain discharge pipe 2 by opening are directly discharged from the discharge tank 5 to the outside of the machine.

When the swing sorting device 10 is stopped by operating the handle 16, even if some grains slip off the sorting plate 11, the grain lifting machine passive pulleys 38 and 39 are still operating.
No grains remain.

According to the present invention, at the same time as the oscillating sorting device is activated and stopped, the opening/closing bottom plate of the equalizer fixed to the oscillating sorting device is closed and opened, thereby making it easier to discharge grains to the outside of the machine. Moreover, by discharging the grains inside the machine, the grain lifting machine will not become clogged, and especially if a thrower is used in the grain raising machine, the blades will not be damaged or damaged by the accumulated grains. Even if some grains slip off the sorting plate when the oscillating sorting device is stopped, the necessary grain lifting machine is still operating, which prevents accidents such as the grain lifting machine becoming clogged. There is no need to worry about accidents even when the entire machine is stopped and restarted. Furthermore, since the grain sorting machine inside the machine can be stopped, energy consumption can be reduced.
