Description

[Detailed description of the invention] This invention relates to a device for removing residual rice from a rice huller.

For rotary sorting machines that use a rotary sorting tube with a large number of pot holes to sort mixed rice, such as paddy and brown rice,
There was a problem in that it took time to remove the remaining rice from the rotary sorting cylinder at the end of the sorting operation, and the sorting operation could not be made more efficient.

This idea aims to shorten the time required to remove the remaining rice from the rotary sorting cylinder at the end of the sorting operation, and also to smoothen the transmission of power from the removal part of the huller to the rotary sorting cylinder. Embodiments of this invention shown in the drawings will be described below.

First, to explain the configuration of the example, 1
1 is a removing section, and this removing section 1 is composed of a paddy tank 2, a pair of removing rolls 3, 3, etc. 4
In the wind sorting section, the rice husks are sorted out from the shedding section 1 by the sorting wind generated by the front suction machine 5 and the rear blower 6, and the rice husks are transferred from the suction machine 5 to the dust exhaust pipe 7. The mixed rice of paddy and brown rice is then discharged outside the machine, and is configured to fall into a dropping rice receiving trough 8 below. The mixed rice is transferred to the rotary sorting cylinder 11 via the mixed rice supply hopper 10 by the mixed rice lifting machine 9 that has fallen into the fallen rice receiving trough 8.

Reference numeral 12 denotes a rotary sorting case, and inside the rotary sorting case 12, a rotary sorting tube 11 having a large number of pot holes on the inner peripheral surface is arranged so that it can rotate in a substantially horizontal state.
The supply side end (right side in FIG. 1) and the discharge side end (left side in FIG. 1) are blocked by drive rollers 13, 13.

The rotary sorting case 12 includes a supply receiving helix 14 which is located inside the rotary sorting tube 11 and which receives the mixed rice from the mixed rice supply hopper 10 and transfers it to the supply side end of the rotary sorting tube 11. a gutter 15, a finished rice receiving gutter 17 having a finished rice helix 16 for transferring the brown rice sorted through the pot hole of the rotating sorting tube 11;
A mixed rice receiving trough 19 having a mixed rice helix 18 for transferring paddy and some brown rice scooped up by the pot hole of the rotating sorting tube is installed horizontally. The lower end of the rotary sorting case 12 from the removal part 1 is pivotally supported, so that the supply side end of the rotary sorting case 12 can be rotated upward. 20
is a rotating arm that is pivoted at the rear of the rice huller.
A rotating petal 21 is connected to the base end of the rotating arm 20, and a tip end of the rotating arm 20 is pivotally connected to the rotating sorting case 12.
When the rotary sorting case 12 is rotated downward, the supply side end of the rotary sorting case 12 is lifted. Note that another mechanical device may be employed to move the supply end of the rotary sorting case 12 upward.

The discharge side end of the mixed rice receiving gutter 19 communicates with the dropped rice receiving gutter 8 via the mixed rice dropping tube 22, and the finished rice that has fallen from the discharge side end of the finished rice receiving gutter 17 is transferred to the finished rice receiving gutter 17. The rice is sorted while flowing down the falling tube 23, the finished rice grain plate 24 and the finished rice gutter 25, and the finished rice is transferred to the finished rice grain lifting machine 2.
It is taken out of the machine at step 6. In addition, 27
28 is a paddy receiving gutter that receives the paddy falling from the discharge side end of the rotary sorting cylinder 11, and a paddy lifting machine 28 returns the paddy from the paddy receiving gutter 27 to the paddy tank 2.

An input shaft 29 to which power is transmitted from a drive source (not shown) is mounted on the detached portion 1 . 30 is
The power extraction shaft 30 receives power from the input shaft 29 through a bevel gear (not shown), and is supported so as to protrude toward the rotary sorting cylinder 11 side, that is, toward the rear of the machine body. In addition, the supply helical shaft 14a is made to protrude from the rotating sorting case 12 side toward the removal part 1 side, that is, toward the front side of the machine body, so that the axes of the power take-off shaft 30 and the supply helical shaft 14a are aligned, and both shafts are 30 and 14a are interlocked and connected by a universal joint 31, and the power transmitted from the power take-off shaft 30 on the removing part 1 side to the supply helical shaft 14a drives the finishing rice helix 14 and the mixed rice helix 18, and also drives the supply helix 14. Spiral pulley 3
drive roller 1 via a belt (not shown)
Power is transmitted to a drive roller shaft 33 that drives the rollers 3 and 13. In addition, 34 is a universal joint collar fixed to the power take-off shaft 30 with a bolt 35, and 36 is a universal joint 31 and a universal joint collar 34.
Safety pin 37 is attached between safety pin 36
This is a wire to prevent it from falling off.

Next, the operation of the embodiment will be explained. When carrying out hulling work, raw rice is supplied to the rice tank 2, and each rotating part of the hulling machine is driven. Then, the paddy supplied from the paddy tank 2 to the de-rolls 3, 3 is de-rolled, the scraped rice falls to the wind sorting section 4 below and is wind-selected, and the rice husks are sent to the suction machine 5 and the dust exhaust pipe. The mixed rice of brown rice and paddy is discharged to the outside of the machine through 7, and the mixed rice of brown rice and paddy falls into a rice receiving trough 8, and is supplied to a mixed rice supply hopper 10 by a rice lifting machine 9, and further,
It is supplied to the supply side end of the rotary sorting tube 11 by the supply helix 14 .

The mixed rice supplied into the rotary sorting cylinder 11 is
The brown rice is inserted into the pot hole of the rotary sorting tube 11 rotating clockwise in the figure and scooped up, and falls into the finished rice receiving gutter 17, and from the discharge end of the finished rice receiving gutter 17 to the finished rice dropping tube 23. , a finished rice flow grain board 24, a finished rice gutter 25, and then taken out of the machine by a finished rice grain lifting machine 26. In addition, the paddy and some brown rice that have been scooped up by the pot hole of the rotary sorting tube 11 and dropped into the mixed rice receiving trough 19 fall from the discharge side end through the mixed rice falling trough 22 and into the dropped rice receiving trough 8. It will be reprocessed. Further, the paddy flowing down from the discharge side end of the rotary sorting tube 11 to the paddy receiving trough 27 is returned to the paddy tank 2 by the paddy lifting machine 28.

The hulling work is carried out in this way, but when the grain remaining in the rotary sorting cylinder 11 is to be removed near the end of the work, the rotary pedal 2
1 downward, rotate the rotary arm 20 clockwise, lift and tilt the supply side of the rotary sorting case 12, and remove the grains remaining in the rotary sorting cylinder 11 from the discharge side end. Drop the rice and take it out of the machine via the paddy receiving trough 28 and the paddy lifting machine 29 (at this time, rotate the tip of the paddy lifting machine 29 to take it out of the machine).Remove the remaining rice. can be done quickly. Note that even when the rotary sorting case 12 is tilted, the power is smoothly transmitted from the power take-off shaft 30 on the removal part 1 side to the supply helical shaft 14a on the rotary sorting case 12 side via the universal joint 31. In addition, if the rotary sorting cylinder 11 becomes clogged with grains and power transmission becomes unreasonable, the safety hinge 36 is disconnected, preventing damage to the machine body and preventing inspection. Even when starting repair work, since the safety pin 36 is located at the intermediate portion between the detached part 1 and the rotary sorting case 12, the repair can be carried out quickly.

In this invention, a rotary sorting case 12 that rotatably supports a removing part 1 and a rotary sorting cylinder 11 is arranged side by side on the machine body, and the rotary sorting case 12 is attached to the removing part 1.
The rotary sorting case 12 is configured to be movable up and down around the lower part of the vicinity, and has a power take-off shaft 30 mounted on the removal part 1, and a grain receiving trough 15 located in the rotary sorting cylinder 11. This is a residual rice processing device for a huller, in which a helical shaft 14a mounted on the hull is disposed facing each other, and both shafts 30 and 14a are transmission-connected by a universal joint 31. Sometimes, when removing the residual rice in the rotary sorting cylinder 11, only the rotary sorting case 12 is rotated and tilted so that the remaining rice can be easily taken out. Even when the huller is in motion, power is always transmitted from the power take-off shaft 30 on the removing section 1 side to the run shaft 14a on the rotary sorting side via the universal joint 31. Compared to the previous model, there is no need to adjust the power transmission state, and the remaining rice can be removed quickly.
