Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a hulling device using a grain sorting section having a rotary sorting cylinder, which is designed to have a small size as a whole and to allow the grains to advance one after another while changing the flow direction without stagnation. This is what I did.

Conventionally, a grain sorting section having a rotary sorting tube whose shaft center is in the left and right direction is provided on the left and right sides of a hulling section having rolls whose shaft center is in the front and back direction, and a grain selection receiving section is provided in the grain selection section. There is a known hulling and sorting machine in which a grain lifting device from the hulling section to the grain selection section receiving section is provided between the hulling section and the grain selection section receiving section. The entire structure was large, and there was a tendency for the grain to become clogged as it progressed while changing its flow direction from front to back to left and right.

Therefore, the present invention provides a grain sorting section having a rotary sorting tube whose axis is in the left-right direction with a gap between the left and right sides of the hulling section having rolls whose axis is in the front-back direction, and A grain receiving section for supplying grain to the grain sorting section is provided between the grain sorting section and the grain sorting section, and a grain receiving section is provided between the hulling section and the grain selection section receiving section. A grain lifting device leading to the receiving section is provided, the upper end of the grain lifting device overlaps the grain selection section receiving section in the front and back direction, and the upper end section is discharged in the front and rear direction to the grain selection section receiving section. This is a rice huller sorting machine designed to be supplied to the rice huller.

To explain one embodiment of the present invention with the drawings, l is the hulling part 3
A hulling hopper 1 is provided with a hulling chamber 2 in the lower part of the hulling hopper 1, and a pair of hulling rolls 3.3 whose axes extend in the front and rear directions are mounted inside the hulling chamber 2. .

Thus, the grain sorting section 12 is provided adjacent to the left and right sides of the hulling section 31 with a gap 33 therebetween. Inside the grain sorting section 12, a rotary sorting cylinder 13 whose axis is in the left-right direction is rotatably installed horizontally.

Reference numeral 14 denotes a rotating drum of the rotary sorting tube 13, and as is well known, the rotating drum 14 has a large number of pot holes 15 formed on its inner surface.

Inside the rotating drum 14, a horizontal brown rice collection spiral receiving trough 16 and a horizontal feeding spiral trough 17, each having a substantially U-shaped cross section, are arranged side by side. The brown rice recovery spiral receiving trough 16 is horizontally installed nearer to the rotation rising side 18 of the rotating drum 14. 19
20 is a helical conveyor installed horizontally on the brown rice collection spiral receiving gutter 16, and 20 is a helical conveyor installed on the supplying spiral gutter 17. Reference numeral 21 denotes an adjustment plate attached to the rotating rising side 18 of the brown rice collection spiral receiving trough 16, and it is undulated to adjust the separation of brown rice and mixed rice.

A mixed rice receiving trough 22 is installed between the brown rice collection spiral receiving trough 16 and the inner wall of the rotating ascending side 18 of the rotating drum 14. As shown in FIG. 1, when viewed from the side of the rotary sorting tube 13, the receiving gutter 22 is installed biased toward the supply side 23 from the center, and is not installed toward the discharge side 24 from the center. Not yet.

The mixed rice receiving gutter 22 passes under the brown rice recovery spiral receiving gutter 16 and communicates with the supplying spiral gutter 17. A grain sorting section receiving section 25 is provided at a position of the supply spiral gutter 17 facing the hulling chamber 2 side. A grain frying device 2 is installed at the discharge end of the mixed rice receiving trough 9.
6 are connected to each other, and the upper end 32 of the grain lifting device 26 opens above the grain selection section receiving section 25, but the upper end of the grain lifting device 26 is lower than the upper surface of the grain selection section 12.

That is, the grain lifting device 26 is provided in the gap 33 formed between the huller section 31 and the grain sorting section 12, and
overlaps with the grain selection section receiving section 25 in the front-rear direction, and its upper end 3
2 is discharged in the front-rear direction and supplied to the grain selection section receiving section 25.

The lower part of the receiving part 25 of the grain sorting section is formed into a gutter, and the grains flow in the left and right direction and are guided to the spiral gutter 17 for supply.

27 is a grain frying device for removing brown rice.

Next, we will discuss the effect.

First, when the raw material, unhulled rice, is supplied to the loading hot spring in the hulling section 31, it flows down the loading hopper 1 and into the hulling chamber 2, between the hulling rolls 3.3 whose axis is in the front-rear direction. The paddy is removed from the hull, falls on the flow plate 5, and flows into the winnowing chamber 4. In the wind selection chamber 4, suction air is blown by the action of the suction fan 6, so that the light rice husks are discharged from the discharge port 8 through the discharge pipe 7. The immature grains collide with the partition plate 11 and flow into the immature grain receiving gutter 10, and then move to the second conveyor 30 whose axis is in the left and right direction.
is discharged to the outside.

The mixed rice of the unhulled brown rice and the unhulled rice left after the hulling flows into the mixed rice receiving gutter 9, and the axis on the mixed rice receiving gutter 9 passes through the second conveyor 29 in the left and right direction. The grain is fed to the lower end of the grain frying device 26, is fried, and moves up the upper end 32 that overlaps the grain receiving section 25 of the grain sorting section 12 in the front and back sides, and The grains are discharged from the grain selection section 32 in the front-rear direction and supplied to the grain selection section receiving section 25.

Then, the shaft center is flowed and supplied from the receiving part 25 of the grain sorting section to the supply spiral gutter 17 in the left and right direction, and is fed laterally in the left and right direction by the cross-feeding action of the helical conveyor 20, and then from the drop port 28 to the rotary drum 14. Feeds falling within.

Then, the mixed rice that fits into the pot hole 15 is fried by the rotation of the rotating drum 14, and the mixed rice is transferred to the mixed rice receiving trough 2.
2, the mixed rice flows down through the mixed rice receiving trough 22, flows into the supply spiral trough 17, and circulates within the rotating drum 14.

At this time, since the mixed rice receiving trough 22 is attached only to the supply side 23 from the center of the rotating drum 14, there is no possibility that the mixed rice receiving trough 22 will not function smoothly due to too much intake.

Conventionally, a grain sorting section having a rotary sorting tube whose shaft center is in the left and right direction is provided on the left and right sides of a hulling section having rolls whose shaft center is in the front and back direction, and a grain selection receiving section is provided in the grain selection section. There is a known hulling and sorting machine in which a husking device from the hulling section to the grain selection section receiving section is provided between the hulling section and the grain selection section receiving section. The entire structure was large, and there was a tendency for the grain to become clogged as it progressed while changing its flow direction from front to back to left and right.

However, the present invention provides a grain sorting section 12 having a rotary sorting tube 13 whose axis is in the left-right direction with a gap 33 on the left and right sides of the hulling section 31 which has the rolls 3 whose axis is in the front-back direction. A grain selection receiving section 25 for supplying grain to the rotary sorting cylinder 13 is provided between the hulling section 31 and the grain selection section 12. A grain lifting device 26 extending from the hulling section 31 to the grain selection section receiving section 25 is provided in between, and the upper end portion 32 of the grain lifting device 26 overlaps with the grain selection section receiving section 25 in the front-rear direction. Since the grain lifting device 26 is equipped with a huller, and the upper end portion 32 is configured to be discharged in the front-rear direction and supplied to the grain selection portion receiving portion 25, a. Since it is provided between the grain sorting section 12 and the grain sorting section 12, the whole can be made compact.

The grain lifting device 26 includes the hulling section 31 and the grain sorting section 1.
2, the grain frying device 26 itself can be made small and inexpensive.

C. A structure in which a grain sorting section 12 having a rotary sorting tube 13 whose axis is in the left-right direction is provided with a gap 33 on the left and right sides of the hulling section 31 having the rolls 3 whose axis is in the front-back direction, This is the basic configuration of this type of rice huller sorting machine, but with this configuration,
Since the grain sliding direction changes halfway, it may become clogged. However, in the present invention, there is a gap between the hulling section 31 and the grain selection section receiving section 25. A grain frying device 26 is provided, and an upper end portion 32 of the grain frying device 26 is provided so as to overlap in the front-rear direction with respect to the grain selection section receiving portion 25,
