Abstract

PURPOSE:To satisfactorily maintain the sorting states of a rotary selection cylinder and a small rice selector by properly arranging the selection directions of both and simultaneously tilting and controlling both to the same direction. CONSTITUTION:When fluidization state of grain to a discharge side from a feed side is fluctuated by both the kind of grain to be selected and the rate of water content and selection state is impaired, gradient of a rotary selection cylinder 11 to the discharge side from the feed side is controlled by controlling and operating a tilt controlling means 24. Thereby the layer thickness of the grain to be selected in the cylinder 11 is properly controlled and both selection efficiency and selection precision are maintained. Further, in case of controlling this gradient, the tilt angle of a small rice selector 25 whose selection direction is properly arranged together with the rotary selection cylinder 1 is simultaneously and similarly controlled to the selection terminal side from the selection initial side and therefore, fluidization state in the small rice selector 25 is improved and the selection states of both are satisfactorily maintained.

Description

[Detailed Description of the Invention] [Field of Industrial Application] This invention is a rotary sorting tube that has a large number of potholes on its inner circumferential surface and rotates approximately around a horizontal axis, for separating mixed rice of paddy and brown rice. This relates to a rice huller for sorting.

[Prior art and problems to be solved by the invention] As a prior art, paddy and brown rice are separated using a rotary sorting tube that has a large number of potholes on its inner circumferential surface and rotates approximately around a horizontal axis. There is a huller sorting machine that sorts mixed rice. There is also a configuration in which a small rice sorting device is placed above this rotary sorting cylinder.

In this conventional device, when the millet sorting device is installed above the rotating sorting tube, the feed side, which is the sorting starting end of the rotating sorting tube, and the supply side, which is the sorting starting end of the millet sorting device, are opposite to each other. It was located in the direction. Therefore, when the inclination angle of the rotary sorting cylinder from the supply side to the discharge side is adjusted, the inclination angle of the small rice sorting device placed above from the sorting start end to the sorting end side changes in the opposite direction. Although the sorting efficiency and sorting accuracy of the one-rotation sorting cylinder improved, the sorting efficiency of the Xiaomi sorting device decreased.

Therefore, the present invention aligns the sorting directions from the sorting start end side to the sorting end side of the rotary sorting tube and the millet sorting device, so that the rotary sorting tube and the millet sorting device can be tilted in the same direction at the same time. The aim is to eliminate the shortcomings of

[Means to solve the problem]

The technical means for solving such technical problems of the present invention include a shedding section 1, a dropped rice sorting section 4 for wind-selecting the fallen rice from the shelling section 1, and a large number of parts on the inner peripheral surface. In a rice hulling machine equipped with a rotary sorting tube 11 configured with a pot hole and rotating around a horizontal axis to sort mixed rice of paddy and brown rice, the rotary sorting tube 11 is arranged from the supply side to the discharge side. The degree of inclination of the rice grains is adjusted freely, and the sorting start end side of the millet sorting device 25 disposed above the rotary sorting tube 11 corresponds to the feed side which is the sorting start end side of the rotary sorting tube 11, and The sorting end side of the sorting device 25 corresponds to the discharge side which is the sorting end side of the rotary sorting cylinder 11, and the rotary sorting cylinder 11 and the small rice sorting device 25 are connected to each other.
The structure of the hulling machine with a small rice sorting device is constructed such that the inclination can be freely adjusted.

[Function and effect of the invention]

During the sorting work in the rotating sorting cylinder 11, the brown rice that has been pumped up high through the pot hole of the rotating sorting cylinder 11 is sent to the upper finishing rice trough 1.
The rice mixed with unhulled rice and some brown rice that has been drawn up to a low level falls into the rotary sorting cylinder 11 and is sorted while flowing from the supply side to the discharge side. The flow condition of grains to be sorted from the supply side to the discharge side may change depending on the type of grain, the level of moisture content, etc., and the sorting condition may deteriorate, but in such a case, the slope adjustment means 24 can be adjusted. It operates to adjust the degree of inclination of the rotary sorting tube 11 from the supply side to the discharge side, to appropriately adjust the layer thickness of the grains to be sorted in the rotary sorting tube 11, and to maintain sorting efficiency and sorting accuracy. In addition, when adjusting the inclination of the rotary sorting cylinder 11, the inclination angle from the sorting start end side to the sorting end side of the millet sorting device 25 is also adjusted in the same way, so that the inside of the millet sorting device 25 can be adjusted. The flow state of the grains to be sorted becomes good as well, and the sorting efficiency of the rotary sorting cylinder 11 and the sorting efficiency of the small rice sorting device 25 can be synchronized, and the sorting condition of both can be maintained in a good condition. It is something.
