Description

[Detailed description of the invention] The present invention relates to improvements in rice hulling sorting equipment.

Conventional rice hulling sorting equipment is usually equipped with a multi-tiered oscillating sorting plate that sorts grains of different types according to the difference in friction coefficient and specific gravity during the sorting process. The oscillating sorting plate has the advantage of being able to carry out extremely high-precision sorting, and can also sort mixed grains of wheat and rice by adjusting the inclination angle of the sorting plate, but the overall size of the device becomes extremely large. However, it has the disadvantage that it is large in size and generates strong vibration and noise, which worsens the working environment.

Therefore, the present invention provides a large number of pot holes on the inner peripheral surface, and
A unique rotary sorting tube is provided in which a grain size sorting section with a brown rice catcher suspended horizontally in the cylinder is connected to a grain size sorting section consisting of a perforated wall tube, and the sorting tube is connected to a swinging sorting section. By arranging it in relation to the previous stage of the nine-oscillating sorting plate to form a consistent sorting process, the grain size sorting section of the rotating sorting cylinder is provided with a particle size sorting section. The grain size sorting section separates small particles such as immature grains and broken grains that are mixed into the sorted grains, and also separates approximately % of the brown rice from the mixed grains of paddy and brown rice in the sorted grains to determine the grain volume. The mixed grains are reduced by almost half, and the mixed grains are fed to a small-sized oscillating sorting plate to perform high-precision grain sorting, thereby sorting by combining the characteristics of various sorting actions. The efficiency and accuracy are greatly increased, the entire device is made as small as possible, the weight of the device is significantly reduced, and high-precision sorting is always carried out to smoothly and quickly mass-produce selected brown rice. The aim is to develop and provide high-performance equipment.

The present invention will be explained with reference to embodiment figures. Symbol (1) is a box-shaped machine base with a built-in wind sorting section (2), and a pair of de-wall rolls (8) and (4) are mounted on the upper side of the machine base (1), and the pressure-sweeping process is carried out. (5) and a swinging sorting part (8) consisting of a swinging sorting plate (6) and a swinging device (7) are arranged in parallel on the other side. A grain size sorting section (11) K is provided with a pot hole (9...) in which a brown rice catcher (lO) is suspended horizontally in the cylinder, and a grain size sorting section (12) is made of a perforated wall tube.
) are connected to integrally form a rotary sorting tube (18), and the rotary sorting tube (18) is mounted horizontally on the upper part of the swinging sorting plate (6) provided in the swinging sorting section (8). is a rice huller sorting device installed diagonally horizontally to form a consistent grain sorting process.
