Description

[Detailed Description of the Invention] The present invention relates to a mounting device for a downflow gutter in a color sorter for granular materials that sorts granular materials such as grains according to their color.

Conventionally, the central part is a hole through which the grain passes, a background is provided below the hole through which light from a light source can be freely adjusted, and a light source and a sensor for reflected light are formed above. In addition to forming a sensing part, a discharge port is provided behind the sensing part in the outflow direction of the passage hole, and a discharge port for non-standard products is provided in front of this discharge port so as to be orthogonal thereto. A grain sorting mechanism is known as Japanese Patent Application Laid-Open No. 51-27568, in which an injector is installed above the outlet for non-standard products so that the nozzle faces the outlet. Because the length between the downflow gutter and the outlet in the downstream direction cannot be adjusted, the flow of grains at the sensing section cannot be adjusted appropriately.

In addition, in a type of transfer device in which the head of a screw is suspended between two chute rails that are inclined parallel to each other and it slides down, it is possible to attach a tapered screw to the top of the support frame that matches the slope of the chute rail and is symmetrical to the downward slope. A tapered support seat is provided, and weir plates are protruded from both sides of the front and rear ends of this support seat, and each outer surface of two chute rails supported through the center of this support seat and each of the weir plates are provided. A wedge-shaped adjustment piece, which is longer than the support seat, is slidably inserted between the inner tapered seat surface and the adjustment piece. The chute rail is fixed to the chute rail using an adjustment bolt whose tip is screwed into the side surface of the chute rail from the outside of the weir plate, and a sliding adjustment piece is installed at the bottom of the fixed position of the parallel chute rail to adjust the chute spacing. A cut groove is provided in the upper part of one side of the weir plate, and the chute of the chute rail is fitted with a horizontal pin whose base end is fitted so as to be movable up and down. A screw transfer mechanism in which guide rails are supported and placed along the center line at appropriate intervals was developed in 1987-4568.
This is known as Publication No. 7, but the chute rail cannot be moved in the longitudinal direction.

The purpose of the present invention is to eliminate the above-mentioned drawbacks, to allow the downflow gutter to be installed or removed from the front of the color sorter control panel, and to make the length of the flow path between the downflow gutter and the receiving gutter the same.
