Description

[Detailed Description of the Invention] The present invention relates to an improvement of an opening / closing control device for a shutter of a grain tank mounted on the body of a harvester such as a combine harvester.

The grain tank 1 mounted on the body of the harvester is equipped with a sliding shutter 2 at the grain discharge port 10 at the bottom thereof, as shown in FIG. By opening the discharge port 10 by the
The grains inside are discharged to the chute 3 connected to the discharge port 10.

As shown in FIG. 2, the shutter 2 provided in the discharge port 10 of the grain tank 1 in this manner is, as shown in FIG.
An opening 21 sized to wrap around the discharge port 10 and a blind plate lid 22 sized to close the discharge port 10 are formed in parallel in the longitudinal direction, and the front side of one end in the longitudinal direction ( As shown in FIG. 2, the lower end of the discharge cylinder portion 11 of the tank body 1a of the grain tank 1 is configured by forming a gripping portion 23 that slides to the right (in FIG. 2). When the outlet 1b is attached to the outer periphery of the plate 1 by the plate 13 formed in the shape of a tightening band also as a fitting for the chute 3, the shutter 2 is preliminarily set in the window hole 12 provided in the outlet 1b in the longitudinal direction. The main body 1a of the outlet 1b is inserted so that it can slide freely.
Is attached to the tank body 1a by sliding along the lower surface of the discharge port 10 formed at the lower end of the discharge cylinder portion 11 of the tank body 1a to open and close the discharge port 10.

The opening / closing restricting means for allowing the shutter 2 to correctly perform the operation of opening the discharge port 10 and the operation of closing the discharge port 10 is pulled out of the shutter 2 and the discharge port 10 is opened. When the opening 21 is properly wrapped around the lower surface of the discharge port 10 during the opening operation, as shown in FIG. 1, the rear surface 11a (in FIG. 1) of the peripheral wall of the discharge cylinder portion 11 of the tank body 1a. Stopper 4 that abuts the left side) and stops the shutter 2 at that position
When the shutter 2 is pushed in and the discharge port 10 is closed, when the cover 22 of the blind plate properly overlaps the lower surface of the discharge port 10, the outer periphery of the discharge cylinder part 11 of the tank body 1a is The outlet 1b to be mounted is provided with a stopper 5 that abuts against the front surface (right surface in FIG. 1) and stops the shutter 2 at that position.

By the way, these stoppers 4 and 5 restrict the discharge port 10 to the open position in the stopper 4 provided on the front end side of the shutter 2, and it is not necessary to consider the leakage of the grain. At a position continuous with the opening 21,
The back wall 11a of the discharge cylinder 11 of the tank body 1a is simply formed in the shape of a vertical wall plate that rises from the edge of the opening 21 on the tip side, and when the opening 21 properly wraps with the discharge port 10. I will try to regulate it at that position. And, for this reason, the vertical wide wall is the discharge cylinder portion 11.
Will collide with the rear surface 11a of the tank body 1a
It is designed not to hurt. However, in the stopper 5 provided on the front side of the shutter 2, when the shutter 2 is pushed in and the blind cover 22 completely closes the discharge port 10, the stopper 5 is held at that position. Since it is for the purpose, since there is a constraint that it has to be formed so as to prevent the grains from coming around to the chute 3 side, as shown in FIG. 1, the plate member 20 forming the shutter 2 is formed. Since the rib-shaped stopper 5 is formed in a rib shape protruding upward, the rib-shaped stopper 5 is formed every time the front surface of the rib-shaped stopper 5 hits the upper edge of the window hole 12 provided in the outlet 1b. The sloping hem portion 50 on the front surface side of 5 is pushed up by penetrating below the lower edge of the discharge cylinder portion 11 over the outlet 1b, thereby deforming and damaging the tank body 1a. It has caused the problem.

The present invention has been made to solve this problem, and a stopper 5 formed by forming a rib shape on the upper surface of the shutter 2 in front of the lid 22 of the blind plate forms the shutter 2 in the closed position. The present invention proposes new means for effectively preventing the deformation / damage of the tank body 1a when it is pushed into.

Further, in the present invention, as means for achieving this object, a window hole provided in an outlet to be assembled to the tank body is fitted and inserted into the bottom surface side of the discharge port at the lower end of the discharge cylinder portion at the bottom of the tank body. In the shutter that can be pushed and pulled freely, a stopper that restricts the movement of the shutter in the pulling direction is formed on the front end side of the shutter so that the left and right lengths are shortened. In addition, a stopper for restricting the movement of the shutter in the pushing direction is formed by being formed in a rib shape that is longer to the left and right than the stopper, and the outlet has an upper edge to a lower edge of the window hole at the upper surface of the shutter. Is provided with a hanging wall having a substantially reaching length, and a notch having a size that allows passage of the stopper on the tip side is formed at the central portion of the lower edge of the hanging wall,
On both sides of the notch, we propose a shutter opening and closing control device in a grain tank that is equipped with abutting parts that abut the left and right ends of the skirt on the front side of the front side stopper described above. is there.
