Description

[Detailed Description of the Invention] (Field of Industrial Application) The present invention relates to the framework of a multistage grain sorting device.

(Prior Art) The conventionally known Japanese Utility Model Publication No. 40-3087 describes a system in which several sorting plates are assembled in stages on left and right vertical plates.

Furthermore, as shown in Fig. 3, in a multi-stage grain sorting device made by stacking and stacking multiple stages of square frames with rotary sorting cylinders mounted on their shafts, the upper edge of the lower square frame a is bent at a right angle. bending the horizontal flange b;
A horizontal flange d bent at right angles is formed on the lower edge of the upper middle square frame c, and the horizontal flange b and the horizontal flange d are fixed with bolts e, and a dust-proof wall f prevents the accumulation of bran dust. The framework of a multi-stage grain sorting device is known.

(Problem to be solved by the invention) In the former method, sorting plates are attached in stages inside a vertical plate, but the above-mentioned known method can be implemented in the case of a sorting plate; In the case of a cylinder, it is difficult to implement.

In the latter case, the lower horizontal flange b of the lower rectangular frame a and the upper horizontal flange d of the middle rectangular frame c are bent at right angles, so simply stacking the upper rectangular frame c on the lower rectangular frame a will cause lateral slippage. Because of this, it was necessary to secure it with bolt e. Further, since the upper flange d is vertical and horizontal, bran dust is likely to accumulate thereon, so a dust-proof wall f is provided above the upper flange d.

(Purpose of the invention) Therefore, the present invention is a framework that does not necessarily require bolts, does not require any dust-proof walls, and is extremely easy to position.

(Means for Solving the Problem) The present invention is a multi-stage grain sorting device made by stacking and stacking a plurality of square frames on which rotary sorting cylinders are mounted on the axis, in which the upper edge 4 of the lower square frame 2 is A lower inclined flange 5 that descends as it goes inward is bent.
At the lower edge of the square frame loaded on the upper part of the lower square frame 2, there is an upper inclined flange 8 which descends as it goes inward.
The upper inclined flange 8 is assembled onto the lower inclined flange 5 by overlapping the upper inclined flange 8 to form a frame of a multi-stage grain sorting device.

(Example) An example of the present invention will be described with reference to the drawings.
is formed by combining angle steel with the lower frame.
Reference numeral 2 denotes a lower square frame at the bottom, which is surrounded by side walls on the front, rear, left and right sides, and has one or two rotary sorting cylinders 3 mounted therein.

The upper edge 4 of the lower square frame 2 forms a lower inclined flange 5 bent inward. The lower inclined flange 5 has a shape that descends as it goes inward, and preferably has an inclination of about 45 degrees.

6 is a middle square frame that is loaded and polymerized on the lower square frame 2,
The lower edge 7 of the middle square frame 6 is bent inward to form an upper inclined flange 8. The upper inclined flange 8 has a shape that descends as it goes inward, and when the upper inclined flange 8 is loaded and superposed on the lower inclined flange 5,
Since the slopes are the same, they come into close contact with each other. The upper edge 4 of the middle rectangular frame 6 is formed to have the same structure as the upper edge 4 of the lower rectangular frame 2.

Reference numeral 9 denotes an upper square frame, which is formed in the same manner as described above.

In the embodiment, the lower inclined flange 5 and the upper inclined flange 8 are fixed by bolts and nuts 10, but this may be omitted depending on the case.

(effect) Next, we will discuss the effect.

Since the present invention has the above-mentioned configuration, the lower square frame 2 is placed on the lower frame 1, the middle square frame 6 is placed on the lower square frame 2,
If the upper rectangular frame 9 is overlapped on the middle rectangular frame 6, the lower inclined flange 5 of the upper edge 4 of the lower rectangular frame 2
Since the upper inclined flanges 8 of the lower edge 7 of the middle rectangular frame 6 overlap, they can be easily positioned.
That alone is enough to use it. In this case, the lower inclined flange 5 and the upper inclined flange 8 may or may not be fixed with bolts and nuts 10.

Although the bran and dust generated during the work are deposited on the upper inclined flange 8, the amount thereof is extremely small because the slope of the upper inclined flange 8 itself is inclined to the angle of repose.

(Effects) In the conventionally known Utility Model Publication No. 1973-3087, the sorting plates were installed in stages on the inside of the left and right vertical plates, but the sorting plates were not attached as described in the publication. This is possible because it is thin and light, but it is difficult to implement in the case of a rotary sorting tube that is tall and has a rotary shaft fixed structure.

The latter publicly known example shown in Fig. 3 is shown in the lower square frame a.
Since the lower horizontal flange b and the upper horizontal flange d of the middle square frame c are bent at right angles,
If the upper rectangular frame c is simply loaded and polymerized on the lower rectangular frame a, lateral displacement will occur, so it was necessary to secure the upper rectangular frame c with bolts e. Further, since the upper flange d is vertical and horizontal, bran dust is likely to accumulate thereon, so a dust-proof wall f is provided above the upper flange d.

However, in the present invention, a multi-stage grain sorting device is obtained by stacking and stacking a plurality of square frames on which rotary sorting cylinders are mounted on the shaft, and the upper edge 4 of the lower square frame 2 has a lower part that descends as it goes inward. An inclined flange 5 is formed in a bent manner, and an upper inclined flange 8 is formed in a bent manner at the lower edge of the square frame loaded on the upper part of the lower square frame 2, and the upper inclined flange 8 descends as it goes inward, and the lower inclined flange 5
Since this is a framework for a multistage grain sorting device in which the upper inclined flange 8 is superimposed and assembled on top, the lower inclined part of the upper edge 4 of the lower rectangular frame 2 can be simply overlapped vertically. As a result of the upper inclined flange 8 of the lower edge 7 of the middle square frame 6 overlapping the flange 5,
Since they are easily positioned, they can be used alone, and the lower inclined flange 5 and the upper inclined flange 8 can be used without being fixed with bolts and nuts 10.

Further, bran and dust generated during the work accumulate on the upper inclined flange 8, but since the upper inclined flange 8 is inclined, they flow down due to vibration.
