Description

[Detailed Description of the Invention] The present invention relates to an opening/closing operation device for a shutter such as a grain processing machine.

In other words, in a shutter such as a grain processing machine that opens and closes by pulling and pushing the lower part of the supply hopper, the shutter can be opened and closed by a lever from the outside of the side plate of the machine, and even when the shutter is open, the shutter cannot be opened or closed. The lever can be well stored inward so that it does not protrude outward from the side plate, and the lever can be kept so that it does not protrude beyond the side plate and interfere with work outside. It is provided that the structure is simple and can be suitably implemented.

Next, the embodiment shown in the drawings will be described.

FIG. 1 shows a side view of a soybean sorter, which is an example of a grain processing machine. A feed roll 7 is mounted on a shaft at the bottom of a supply hopper 1 that supplies soybeans, and a suction roll 7 is mounted on the lower side of the feed roll 7. The dust extractor 8 is visible, and the lower part of the elevator 9 is connected so that soybeans can be fed from the upper part of the elevator 9 to above the sorting belt 10. It is installed so that it can be sorted by a separator 11, and can be received in each container 12 below, so that it has the same structure as the conventional type.

Further, a shutter 2 is slidably inserted into the upper part of the feed roll 7 on the lower side of the supply hopper 1, and when the shutter 2 is opened and closed by pushing and pulling, the shutter 2 is opened fully. The structure is similar to that of the conventional structure, with the end A of the fuselage 2 being installed close to the side plate 3 of the fuselage, which is erected laterally.

The shutter 2 is installed so that it can be opened and closed in the same manner as before by pushing or pulling it with a lever 4 inserted into the hole 13 of the side plate 3, but there is a The lever 4 has a cylindrical metal 14 fixed thereto, a hole 5 that becomes slightly longer in the lateral direction is formed in a portion of the shutter 2 below the inner end of the cylindrical metal 14, and a grip portion 15 is bent at one end. is loosely fitted into the cylindrical metal 14, and a pin 6 which can be removably fitted into the hole 5 is inserted into the tip of the lever 4 so as to form a cross in a direction perpendicular to the lever 4.

Therefore, the pin 6 at the tip of the lever 4 is vertically inserted into the hole 5 of the shutter 2 to link the lever 4 to the shutter 2, and the grip 15 is inserted from the outside as shown in FIGS. 1 to 5. When the lever 4 is squeezed and the lever 4 is pressed, the shutter 2 is closed, and when the shutter 2 is pulled outward, it can be opened as shown in FIG.

As shown in FIG. 6, if the end A of the shutter 2 is kept open against the inner surface of the side plate 3, the lever 4 should be moved from the state shown in FIG.
When the lever is rotated approximately 90 degrees to either the left or right, the pin 6 will come out above the hole 5 and the lever 4 will be separated from the shutter 2. When the lever 4 is pushed inward, the lever 4 is pushed inward of the side plate 3 and the grip 15 is pushed outward of the side plate 3, as shown in FIGS. 7 and 8. It will be in a stored state with only a slight protrusion.

In this way, the present invention provides a shutter for a grain processing machine, etc., in which the lower part of the supply hopper is opened and closed by pulling and pushing the lower part of the supply hopper. The lever and the above-mentioned shutter are constructed so that they can be freely linked and disengaged, so that the shutter can be pulled and pushed and the lever can be stored inside the side plate.The shutter installed in the side plate of the aircraft can be inserted into the side plate from the outside. Opening and closing operations can be performed using a lever inserted through the shutter, and even when the shutter is opened, the link with the shutter is released and the lever is pushed inward of the side plate, so the lever does not protrude far outside of the side plate. This allows the lever to protrude beyond the side plate and prevent it from getting in the way of work outside, and has the advantage of a simple structure that can be conveniently carried out. .
