Description

[Detailed Description of the Invention] 3. Detailed Description of the Invention [Field of Industrial Application] This invention is a rotary sorting tube that has a large number of pot holes on its inner circumferential surface, and is used to sort mixed rice such as paddy and brown rice. It can be used in grain sorting equipment that sorts grains.

[Disadvantages that the prior art and the invention are trying to solve] There is a grain sorting machine that sorts a mixed rice of paddy and brown rice using a rotating sorting tube that has a large number of pot holes on its inner circumferential surface. In this grain sorting machine, a finishing rice gutter for receiving the finished rice is installed in the rotating sorting cylinder, and the finishing rice gutter receives the brown rice scooped up by the rotation of the rotating sorting cylinder. Since the rotary sorting tube rotates around the axis of the sorting tube, there is insufficient vertical movement of the grains to be sorted flowing inside the rotary sorting tube, and the brown rice does not sink to the bottom sufficiently. There was a problem that the efficiency of inserting the brown rice into the hole in the sorting tube was poor.

Therefore, this invention gives more vibration in the vertical direction to the grains to be sorted flowing in the rotary sorting tube compared to conventional devices, increasing the efficiency of fitting the rotary sorting tube into the pot hole, and increasing the sorting efficiency. It is intended to increase the

Means for Solving Problem C] The technical means of the present invention for solving this technical problem is that the rotary sorting cylinder 11 has a large number of pot holes formed on its inner peripheral surface and rotates around a horizontal axis. A finishing rice gutter 16 for receiving brown rice is provided, and a rotating flange 23° 23 is fixed to the outer periphery of the rotary sorting tube 11, which is slidably supported by a drive wheel 12.12 and rotates the rotary sorting tube 11. Rotating flange 2
The structure of the grain sorting device is characterized in that the rotation center of the rotary sorting cylinder 11 is eccentric with respect to the rotation center of the rotary sorting cylinder 11.

[Operation and effect of the invention]

During grain sorting work, the rotary sorting cylinder 11 is driven by a drive wheel 12.
Since the rotation center of the rotary sorting gll is eccentric to the rotation center of the rotary flange 23, the rotary sorting cylinder 11 is forcibly moved up and down and vibrates while rotating. Therefore, the rotating sorting tube 11
The brown rice of the mixed rice inside tends to sink downward, which improves the efficiency of fitting brown rice into the pot hole of the rotary sorting cylinder 11, increases the amount of brown rice scooped up, and improves the sorting efficiency. be.

〔Example〕 Embodiments of the invention shown in the drawings will be described below.

First, the structure of the embodiment will be described. Reference numeral 1 denotes a shedding section, and this shedding section 1 is connected to a paddy tank 2. A pair of depu rolls 3
, 3 etc. Reference numeral 4 denotes a sloughed rice wind sorting path, in which the sloughed rice from the husking section 1 is sorted by the sorting wind generated by the suction fan chamber 5 in front, and the rice husks are passed from the suction fan chamber 5 through the dust exhaust pipe 6 to the machine. The mixed rice of brown rice and paddy is discharged outside and falls into the sliding rice receiving trough 7 below, and the mixed rice that has fallen into the suriring rice receiving @ 7 is sent to the mixed rice lifting machine 8 and the mixed rice supply hopper 9. The rice is then conveyed to the starting end of a supply gutter 14 which also serves as a mixed rice receiving gutter.

Reference numeral 10 denotes a sorting case, and inside the sorting case 10 there is a supply side end (as shown in FIG. right side) and the discharge side end (left side in Figure 2) by driving roller 1.
It is rotatably supported by 2.12. This rotating sorting tube 1
1, a supply @ 14 with a supply helix 13 and a finishing rice trough 16 with a finishing rice helix 15 are installed horizontally.

In arranging the supply gutter 14 and the finished rice gutter 16 inside the rotary sorting tube 11, the finished rice gutter 16 is placed inside the rotary sorting tube 1.
The mixed rice scooped up by the pot hole of the rotating sorting cylinder 11 is arranged so that the supply gutter 14 is arranged from the upper side of the rotating sorting cylinder 11 to the side rotating downwards. The mixed rice falls onto the mixed rice receiving plate part 14a of the supply gutter 14, and is configured to be transferred to the terminal end side of the supply gutter 14 by the supply helix 13, and the supply gutter 14 also functions as a mixed rice receiving gutter. There is.

The discharge side of the finished rice gutter 16 is communicated with the finished rice receiving gutter 19 via the finished rice flow lower tube 17 and the finished rice flow grain plate 18,
While the finished rice falls from the finished rice flow lower tube 17 and the finished rice flow grain plate 18 to the finished rice receiving trough 19, the brown rice that is wind-selected and flows down to the finished rice receiving trough 19 is passed through the finished rice grain lifting machine 20. It is then taken out of the aircraft. A beginner's upper cylinder body 21 is connected to the discharge side end of the rotary sorting cylinder 11, and the unhulled rice that has flowed into the beginner's upper cylinder body 21 is pumped upward and goes to the husking section 1 through the paddy reduction value 22. will be returned.

Next, the supporting state of the rotary sorting cylinder 11 will be explained. The rotary sorting cylinder is slidably supported by a drive wheel 12. A rotating flange 23, 23, which rotates 11, is fixed. Rotating flanges 23, 23 are attached to the rotating sorting tube 11.
In fixing, the rotation center P of the rotary sorting cylinder 11 is offset by a predetermined distance with respect to the rotation center 0 of the rotary flange 23. Therefore, when the rotary sorting tube 11 rotates, it rotates while moving up and down, and the brown rice of the mixed rice in the rotary sorting tube 11 sinks downward as it rotates.

Next, the operation of the embodiment will be explained. Paddy is supplied to the paddy tank 2 of the hulling section 1, and each rotating part of the hulling machine is driven.

Then, the paddy supplied from the paddy tank 2 to the husking section 1 is subjected to the husking action, and the husked rice is sorted by the hushu rice wind selection path 4 below.
The rice husks are discharged from the dust exhaust pipe 6 to the outside of the machine. The mixed rice of brown rice and paddy falls into the sliding rice receiving trough 7, and is sent to the mixed rice grain lifting machine 8 through the mixed rice supply hopper 9 and then to the supply trough 14 on the side of the rotary sorting cylinder 11.
The supply helix 1 in the supply receiver *14 is lifted up and supplied to the starting end side.
3, it is supplied to the supply side end of the rotary sorting cylinder 11.

Next, the mixed rice is scooped up by the pot hole of the rotating sorting tube 11 which is rotating clockwise in Fig. 3, and the brown rice is the finished rice 4iff! 16, the mixed rice of paddy and some brown rice falls into the supply gutter 14 and is sorted, and the unsorted mixed rice that has fallen into the feed gutter 14 is transferred to the feed gutter 14 by the supply helix 13.
From the conveyance terminal end thereof, the material is supplied again into the rotary sorting tube 11 and is re-sorted. In addition, the finished rice that has fallen into the finishing rice gutter 16 is
The finished rice is transported by the finished rice helix 15 to the finished rice flow lower tube 17, passed through the finished rice flow grain plate 18, and falls into the finished rice receiving trough 19, where it is sorted by a sorting wind, and taken out of the machine by the finished rice grain lifting machine 20. It is something.

The sorted paddy sent to the discharge side end of the rotary sorting cylinder 11 is
It flows into the elementary upper barrel 21, passes through the paddy reduction value 22, is returned to the shedding section 1, and is subjected to the shedding action.
