Description

[Detailed description of the invention] In a combine harvester, a grain tank that tilts up and down centering on the side opposite to the handling port is mounted on a threshing device mounted on the machine base. When opening the chamber cover to inspect and maintain the inside of the handling barrel or handling room, or to remove clogged straw waste, there may be a problem with the hydraulic system that raises and lowers the grain tank, or the grain tank may have been raised due to incorrect operation. It is extremely dangerous if it suddenly descends.

The present invention prevents the grain tank from lowering even if the above-mentioned erroneous operation or hydraulic system trouble occurs, and also keeps the handling chamber cover open when servicing or cleaning the handling chamber. The purpose is to provide a safety device for combine harvesters that allows safe work.

The embodiment shown in the drawings will be described below. Reference numeral 1 denotes a threshing device mounted on one side of the machine base 2 of the combine harvester,
On the other side, a take-out part 5 is attached by front and rear supports 4, 4 protruding from the side wall and the grain lifting cylinder 3, and a hanging rod 7' protruding from the front and rear support frame 6 toward the other side.・・・・・・
faces directly below the take-out port 5a of the take-out portion 5, and a pedestal 9 for the paddy bag 8 is provided below it.

A grain tank 7 mounted on the top surface of the threshing device 1 and the top surface of the take-out part 5 is pivotally supported at the outer end of the take-out part 5 with a support shaft 10 so as to be tiltable up and down.
A hydraulic cylinder 11 whose upper portion is pivotally connected to the support frame 6 causes the grain tank 7 to tilt up and down via its rod 12 and turnbuckle 13.

Further, a cylinder cover 15 that covers the upper surface of the handling chamber 14 is attached to an upper cover 17 that can be opened and closed by a hinge 16.
The screws 19.19 are removably screwed onto the cantilever frames 18, 18 provided at the upper part of the culm opening 14b and the culm opening 14b.
19 supports the grain tank 7.

Reference numeral 20 denotes a stay whose base part is fixed to the cantilever frame 18 on the side of the culm opening 14b and whose upper part projects upward from a long hole 17a bored in the upper cover 17.
The base of the support column 21 is rotatably attached by a pin 22, and when the grain tank 7 is lowered as shown by the solid line in FIG. When the interior of the handling room 14 is to be maintained and inspected, the grain tank 7 is tilted upward, the support 21 is pulled up diagonally as shown by the chain line in FIG. 1, and its upper end is attached to the bottom surface of the grain tank 7. After inserting it into the recess of the channel-shaped receiver 23, insert the receiver 23.
Set pin 24 in hole 23 a of the column and hole 21 a of the support 21
Penetrate through and secure with snap pin 25.

Next, the rod-shaped stopper 26, which is rotatably supported by a seat 26a in the middle of the column 21, is placed in a position along the length of the elongated hole 17a as shown by the dotted line in FIG. 5, and then the upper cover is removed. 17 is opened and the stopper 26 is rotated 90 degrees, the upper cover 17 is locked in the open state by the stopper 26 as shown by the chain line in FIG.

Then, when the maintenance work in the handling room 14 is finished, the upper cover 17
Slightly push up the stopper 26, rotate the stopper 26 by 90 degrees so that it aligns with the long hole 17a, and then close the upper cover 17 and tighten with the screws 19.19.

After that, the set pin 24 is removed, the support 21 is removed from the support 23, the set pin 24 is attached only to the hole 21a of the support 21, and the grain tank 7 is lowered.

In addition, in the drawing, 27 is the fourth opening, and 28 is the straw chest.

As mentioned above, this invention is based on a threshing device mounted on the machine stand.
A combine harvester in which a grain tank that tilts up and down centering on the side opposite to the handling port 14C is mounted, and the upper cover of the threshing device is opened and closed centering on the side opposite to the handling port. A support is provided to maintain the upward tilting position, and a stopper is attached to this support to maintain the open position of the upper cover.When the grain tank is raised and the upper cover is opened to maintain the interior of the handling room, the grains are removed. If a problem occurs with the hydraulic system that raises and lowers the grain tank by supporting the tank with supports, or if someone else accidentally operates the hydraulic lever in the lowering direction, the heavy grain tank will lower unexpectedly. It is extremely safe.

In addition, the top cover of the handling chamber can also be kept open with a stopper, which not only ensures safety but also facilitates maintenance work.
