Description

[Detailed description of the invention] The present invention is an improvement of a cylindrical grain sorting-like discharge device.

In general, a common defect of tubular grain sorters is that the outlet is located low and lacks head in relation to the next stroke. Particularly when the height of the grain feeding port is restricted due to its relationship with the previous process, the position of the discharge port will inevitably be lower, resulting in the inconvenience of not being able to provide a communication path to the next process.

Conventionally, as a general example of a countermeasure against this problem, as shown in FIG. There is a structure in which a receiving gutter 3 for falling grains is fixedly mounted at the upper part of the circumference, and the receiving gutter 3 is connected to a discharge port 5 opened in a mantle 4 surrounding the annular shape 1i2. The structure of the gutter 3 has the drawback that the head is significantly reduced and the discharge port 5 cannot be provided with a sufficient height. That is, since the provision of the receiving trough 3 requires a slope for the grains to flow down, the height from the top of the receiving trough 3 to the falling part increases, and the height of the discharge port is greatly reduced.

The present invention has been devised to eliminate this gutter defect by completely abolishing the gutter 3 and to freely set the height of the outlet.

To explain the present invention with reference to FIG. 2, which is an example, a plurality of scoops are formed on the outer peripheral surface of an annular cylinder 9 that rotates integrally with the grain selection cylinder 7 near the end 8 of the rotary grain selection cylinder 7 mounted on the oblique shaft 6. A scooping piece 10 is attached to the outer circumference of the annular tube 9, and the scooping piece 10 rotates along the inner circumferential surface 11, and an annular mantle is provided concentrically adjacent to the grain selection tube 7 with a clearance. 12 is mounted and fixed, and a discharge port 13 is opened at an arbitrary position as high as possible on the annular sleeve 12.

When grain is fed into the grain selection cylinder 7 from the grain feeding hopper 14 provided at the grain feeding opening of the grain selection cylinder 7, fine grains fall out of the grain selection cylinder 7 through the porous wall of the grain selection cylinder 7. Only the large grains are transferred from near the end of the grain selection tube 7 to the annular mantle 12, and are rotated upward along the inner circumferential surface of the annular mantle 12 by the annular pipe 9 scooping piece 10 to lift the grains to the top of the annular mantle 12. It flows out from the outlet 13 opened at the position.

This type of grain sorting cylinder has a grain feeding opening that is limited to a low height.
An important key point is to provide an outlet at the ^ position so that it can be discharged from as high a position as possible.

The present invention can produce the effect of being able to discharge from a gutter hopper or the like provided for discharging.

Claim No. (η) shown in FIG. 3 has a structure in which the discharge port 13 is opened in the centrifugal direction of the outer circumferential surface of the annular sleeve 12. The mounting position of the discharge port 13 has been made as easy as possible compared to conventional devices equipped with
Moreover, since it is not interfered with by protruding equipment such as electric motors, the removal container (bag body) installed on the side of the aircraft is stabilized, and its replacement work is also simplified, improving work efficiency. There are other effects.

The grain sorting cylinder of the present invention can be designed as either a cylindrical cylinder or a polygonal cylinder. The scooping piece of the present invention is also made of plastic material, and its shape can be arbitrarily designed such as a wing piece, a packet, or a plan 21. In short, the gist of the present invention is satisfied as long as there is an effect of stirring and lifting the grains upward within the annular mantle 12.
