Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a transmission device for a pot-and-hole type rotary grain sorting device of a rice hulling device.

BACKGROUND ART Conventionally, some rice hulling devices are equipped with a mixed rice grain sorting device using a pot-and-hole rotary grain sorting method.

This grain sorting device supplies a mixed rice mixture into a rotating cylinder with countless potholes formed on its inner surface, and pulls up the finished rice that has sunk to the lower layer through the potholes into a finished rice receiving trough provided inside the rotating tube. However, since it takes time to take out the remaining rice from the rotary tube at the end of the operation, this grain sorting device is equipped with an inclination adjustment device to adjust the angle of the rotary tube.

This slope tone 1! i) One of the problems with the second grain selection device is that it is difficult to transmit rotational power to the rotary cylinder and to each spiral within the rotary cylinder. In other words, since the rotary cylinder is attached to the huller so that it can be tilted freely, power cannot be directly supplied from the power source attached to the huller by a transmission shaft, and a complicated transmission device is required. It was indispensable, and centering was a hassle, as was replacing the belt.

Therefore, the present invention provides a rice hulling device in which a pothole-type rotary grain sorting type mixed rice grain sorting device is attached, wherein the grain sorting device is provided with the horizontal angle of its rotary tube so as to be adjustable in inclination. A coil spring is used in the bending part of the power transmission device, and the transmission device of the pot-hole type rotary grain sorting device of the hulling device is configured such that the rotary cylinder is rotated via the coil spring. .

is a rotating roll.

A thrower 58 is attached to the side of the mixed rice conveyor 6, and the thrower 58 opens onto a hopper 59 fixed to the end of the mixed rice sorting device 10. It opens onto the passageway 35. 60 is a drop tube.

Next, we will discuss the effect.

When unhulled rice is supplied to the stake hopper 2, the hulling roll 3.3
The rice husks are wind-sorted, the mixed rice falls into the mixed rice receiving trough 8, and the immature rice falls into the unripe rice receiving trough 9. The mixed rice that has fallen into the mixed rice receiving trough 8 is transported horizontally by the mixed rice conveyor 6 and flows into the thrower 58, which is then raised and supplied to the hopper 59. Hopper 59 is
Since it is open to the supply gutter 35, it is transported by the supply spiral 36 to the falling tube 60 at the end, and the horizontal 11!111 rotating tube 23
supplied within.

Since the horizontal shaft rotating cylinder 23 is rotating, the mixed rice becomes a descending layer as it rotates, and is biased toward the rotating upward side 30. Since the lower layer of the falling layer is brown rice, the grain that fits into the pot hole 24 is brown rice, which rises as the horizontal axis rotating cylinder 23 rotates and is taken out to the two-man receiving trough 25 and transferred to the finished rice conveyor. 26 to the take-out port 27 side, fall through the take-out port 27, and then the finished rice is taken out from the rice take-out gutter 28 on the conveyor 2.
9.

However, if the amount of grain fed into the horizontal axis rotation ta 23 is low, or if the sorting efficiency on the falling cylinder 60 side of the rotary cylinder 23 is high, or if the remaining rice etc. in the rotary cylinder 23 is disposed of. For this purpose, operate the rotation lever 17 to adjust the inclination
When the fall barrel 60 side of the rotary barrel 23 is moved upward, the grains supplied into the horizontal shaft rotary barrel 23 are moved to the takeout port 27 side by this one movement, increasing the thickness of the falling layer. The mixed rice is sorted out well, or the remaining rice in the rotary cylinder 23 is discharged.

Therefore, the rotational power of the rotary cylinder 23 tilted with respect to the hulling part l side by the inclination adjustment device 13 and the rotational power of each spiral 26, 34, 36 in the rotating cylinder 23 are provided on the hulling part l side. The rotation Il of the supply spiral 36 from the counter 41 via the output shaft 42! 11137, and the variable pulley 38 attached to the rotating shaft 37 and each driven pulley 47, 48.
49 and 50, the belt 53 is applied to the output shaft 42 and the rotation shaft 37, and the transmission is transmitted to the respective spiral or roll shafts.
are connected via the coil spring 43, so
Since the rotary cylinder 23 can freely transmit power to the inclination of the hulling portion l, and the disk 45 is constantly pressed by the biasing spring 46, the coil spring 43 will not fall off.

Therefore, when replacing the belt 53, the coil spring 43 is removed from the discs 44 and 45, and the rotating shaft 37 is replaced.
A gap is formed between the output shaft 42 and the output shaft 42, and the belt 53 is removed from the gap.

As described in 2 below, the present invention is a rice hulling device which includes several mixed rice grain sorting devices 10 using a pot-hole rotary grain sorting method, and the grain sorting device 10 has a rotary barrel 23. A pot hole type rotary selection of a rice hulling device is provided in which the horizontal angle can be freely adjusted, and a coil spring 43 is used in the bending part of the power transmission device, and the rotary cylinder 23 is rotated via the coil spring 43. Since the transmission device is configured as a grain device, power can be freely transmitted against the inclination of the zero-rotation cylinder 23.

Since the mouth zero disc 45 is constantly pressed by the 1,100-force sublink 46, the coil spring 43 does not fall off.

C. The belt 53 is easy to replace.

Second, since the output shaft 42 and the rotating shaft 37 are connected by the coil spring 43, assembly is extremely easy.

This effect is achieved.
