Configuration. Further, the invention of Japanese Utility Model Laid-Open No. 3-109649 has a configuration in which a protruding portion is disposed on the front side of the fuselage, and all stones are disposed on the rear side.

[0003]

In the former invention, since the rice removing and air-selecting unit is arranged above the impeller type removing unit and the oscillating type of all-stone sorting device, the oscillating type universal unit is used. There is a problem in that the height of the stone sorting device is limited, and only a single Manseki sorting plate unit can be arranged, making it impossible to use a highly efficient hulling sorter. There is a problem that the germ part of the fine-grained paddy is detached since the fine-grained paddy and the pity-rich paddy are shed, and the loss rate of the pity is low, and the sludge removal efficiency is not improved. In the latter invention, the milling unit and the rice milling unit are arranged in front of Mangoku, but only a single Mangoku sorting plate unit is arranged, and a hulling machine with a large processing capacity is provided. There was a problem that can not be.

[0004] The present invention is to solve such a problem.

[0005]

Means for Solving the Problems In order to solve the above-mentioned problems, the invention of claim 1 comprises a paddy wind selection unit 8 for selecting paddy into fine-grained paddy and paddy with a lot of pity. A grain removal unit 2 is constructed by attaching a rice removal unit 9 that winds and removes rice from the removal unit 1 to the right and left, and a small diameter impeller blade is attached to the same removal shaft.

It is characterized in that a guide is provided on the downstream side so that the particles are deviated for each net.

[0006]

According to the first aspect of the present invention, the rice paddy is selected by the paddy wind selection section 8 into paddy rice mixed with fine grain and pity, and the fine paddy is removed by the small diameter impeller 6 of the removal section 1. Since the paddy with a lot of pity is evacuated by the large-diameter impeller 7, it is possible to evacuate the germ from the fine-grained rice while minimizing the loss of the germ.
Rice with high pity can be efficiently escaped with a high escape rate. In addition, since the grain removal unit 1 is disposed on the side of the grain style selection unit 8 of the grain style selection unit 2, the transfer configuration of the sorted rice from the grain style selection unit 8 to the grain removal unit 1 is simplified. be able to.

Oscillating multi-stage sorting unit 25 is arranged, and the sorting unit 3
Since a guide is provided downstream of the nets constituting the nets 2 and 32 to distribute the grains sorted by each net, even in a multi-stage manner, the kernels are sorted and discharged for each of the selected grains, and the processing is performed. The oscillating multi-stage all-stone sorter 25 can constitute a hulling sorter having a large processing capacity.

[0008]

Embodiments of the present invention shown in the drawings will be described below. First, an overall configuration of a hulling sorter will be described with reference to FIGS. This rice hulling sorter uses a swinging-type multi-stage all-stone sorter to remove mixed rice after wind-selection in the grain removal unit 1, the grain wind selection unit 2 that wind-selects grains, and the grain wind selection unit 2. It is composed of a mixed rice sorting section 3 for separating and sorting into paddy and brown rice, a mixed rice frying machine 4, a brown rice frying machine 5, and the like.

The hulling unit 1 is an impeller type hulling device. The hulling unit 1 includes a small-diameter impeller 6 that attaches a small-diameter impeller blade to the same extraction shaft to remove fine-grained paddy, and a large-diameter impeller blade.

The rice is supplied to the rice drain gutter 21 via the downflow path 44, and the bottom plate 32d has a brown rice guide 4 for guiding brown rice to the right.
5, the brown rice is merged to the right side, and supplied to the lower end of the brown rice mill 5 through the brown rice flow passage 46. It is intended to simplify the removal of the sorted kernels of the mangoku sorting plate units 32, 32. In addition, the take-out position of the grain can be variously changed by the layout of the machine.

A supply switching valve 48 and a supply amount control valve 50 are provided below the mixed rice hopper 47 so that the supply can be switched and adjusted by operating a lever. Or, it is configured to be able to switch and supply only the upper and lower one-sided stone sorting plate units 32 or to adjust the supply amount.

Thus, the mixed rice that has been wind-selected in the de-rice milling section 9 is mixed with the mixed rice fryer 4, the mixed rice hopper 47, and the flute 4
After passing through 9, the first net 32 of the mangoku sorting plate units 32, 32
The left and right sides are equally supplied to the upper end portion of a, and are sorted while swinging. The foreign matter removed by the first net 32a is discharged out of the machine from the lower end of the first net 32a, and the paddy sorted by the second net 32b is refined from the lower end of the second net 32b through the paddy flow passage 42. It flows down to the receiving trough 12 and is sent to the small-diameter impeller 6 to be escaped again. The mixed rice sorted by the third net 32c is supplied to the lower part of the mixed rice fryer 4 through the mixed rice flowing down channel 44 and the rice removal trough 21 and is supplied to the whole stone sorting plate units 32, 3
Re-sorted by 2. The brown rice separated and sorted by the bottom plate 32d flows down from the lower end of the bottom plate 32d to the lower portion of the brown rice fryer 5 via the brown rice flow passage 46, and is taken out of the brown rice take-out cylinder 56 outside the machine.

As described above, the swinging-type stone sorting plate units 32, 32 are stacked and arranged in multiple stages behind the grain removal unit 1 and the grain wind sorting unit 2, and the mesh of the stone sorting plate unit 32 ( (The first net 32a, the second net 32b, the third net 32c, and the bottom plate 32d are shown.) On the downstream side, the grains selected for each net are deflected by a guide, so that the grains are sorted even in multi-stages. As a result, a hulling sorter having a large processing capacity can be configured.

Next, a dust-absorbing structure of the brown rice fryer 5 will be described with reference to FIG. The bucket type brown rice fryer 5 includes a frying case 5a, a fry pulley 5b rotatably mounted on upper and lower ends of the frying case 5a, and a fry wound around the fry pulley 5b. It is composed of a belt 5c, a fry bucket 5d attached to the fry belt 5c, a fry box 5e for taking out fried grains, and the like.

In the frying box 5e, a diffusion shelf 53 is provided at an upper portion thereof to diffuse the grains, and the diffused grains are received by a downflow net 54 provided below and guided to flow down. The configuration is such that the rice is taken out from the brown rice take-out cylinder 56 via the 55 and outside the machine. Further, a dust funnel 57 is provided below the downflow net 54, and a dust suction air passage 58 is provided below the dust funnel 57,
