Description

[Detailed description of the invention] Conventionally, a threshing device was mounted on one side of the machine, and a grain tank was installed on the other side to store the grains lifted by a grain lifting machine. It is already known to provide an ejection device in which the ejection pipe is folded in two.

However, when loading the grains in the grain tank onto a transport vehicle parked on the road, it was necessary to tilt the discharge tubes in series, so the upper tube was tilted in series with the lower tube using a hydraulic cylinder, etc. If this condition was not maintained, the weight would increase and the cost would increase considerably.

In order to improve these drawbacks, the upper cylinder is manually rotated and the connected state is maintained with a stopper, and since it is troublesome to extend and retract the upper cylinder each time grains are discharged, In order to eliminate this operation, reaping and threshing work was carried out with the upper cylinder and the lower cylinder standing in series, but the upper cylinder wobbled relative to the lower cylinder and was extremely unstable.

This invention not only allows the upper tube to be easily raised and lowered manually, but also enables stable work even when working in an upright position where the upper tube is connected to the lower tube. The purpose is to provide a grain tank for a combine harvester that can be easily and inexpensively obtained, and is equipped with a threshing device on one side of the machine stand, and on the other side is a grain tank for lifting and transporting the grains by the hoisting machine of the threshing device. A grain tank is installed to store the grains.
In the combine harvester in which the grain tank is equipped with a discharge device in which the upper tube of the discharge tube rises and falls at a portion corresponding to the upper part of the grain tank, the upper tube is parallel to the length direction of the upper tube of the discharge tube and is parallel to the longitudinal direction of the upper tube. It is characterized in that a manual operating lever for raising and lowering the lever is attached so as to be movable forward and backward, and a holder for inserting and removing the manual operating lever is attached to the lower tube.

The embodiments shown in the drawings will be explained below.
Reference numeral 1 denotes a threshing device mounted on a machine platform 3 having a traveling device 2, in front of which a pre-processing device 4 consisting of a reaping device and a grain culm conveying device is installed so as to be movable up and down, and in the rear. A cutter 5 is installed as a straw disposal device.

Further, an operation panel 7 and a driver's seat 8 are provided at the front of the grain tank 6 disposed on the other side of the threshing device 1, and an engine room 9 is provided at the rear.

Furthermore, a discharge thrower 10 constituting a grain discharge device is attached to the discharge side of the transfer spiral disposed at the bottom of the grain tank 6 so as to be tiltable laterally, and the casing 11 has an upper end of a lower cylinder 12a. upper cylinder 1
A discharge tube 12 is connected to the base of the upper tube 12b so as to be able to rise and fall with a hinge 13, and a hook 14 is screwed onto the opposite side of the upper tube 12b from the hinge 13.
A lever 16 having a ring 15 is screwed onto the lower cylinder 12a below it.

A holder 17, which is made of a plate bent in a U-shape and has an insertion hole parallel to the upper tube 12b, is fixed to a portion of the upper tube 12b that is deviated by 90 degrees from the hinge 13 and the hook 14. A U-shaped receiver 18 having an insertion hole is also fixed to a portion of the lower cylinder 12a corresponding to the retainer 17.

Further, the manual operation rod 19 made of a round bar inserted into the holding metal 17 and the receiving metal 18 has a stopper 20 made of a snap pin at the upper part, and a stopper 21 made of a split pin near the lower part.
The upper hole 17a of the retainer 17 has a pair of notches as shown in FIG. 2B, while the lower hole 17b has a pair of notches as shown in FIG.
9 is just a circular hole into which the receiver 1 can slide.
The hole 18a of No. 8 is also a circular hole as shown in FIG. 2d.

Therefore, when driving on the road or storing, the upper cylinder 12
b is bent rearward as shown in FIG. 1 and supported by a support 22, and when performing reaping and threshing work, the manually operated rod 19 is moved to the stopper 2 as shown in FIG.
0 until it touches the upper end of the retainer 17 and then push it down, the upper tube 12b will stand up, so hook the hook 15 onto the hook 14, turn the lever 16 downward to tighten it, and then manually operate. Rod 19

It locks into place so it won't fall off.

When reaping and threshing work is performed in such a state, and the grain tank 6 is full, the discharge thrower 10 is

In the case where the discharge tube 12 tilts laterally, the lower tube 12 must be rotated by extending a hand from the cockpit 8 and grasping the rod 19.
a to the grain tank 6 by appropriate means in an upright position.

As mentioned above, the present invention has the threshing device 1 mounted on one side of the machine stand 3, and the grain tank 6 for storing the grains lifted by the grain lifting machine of the threshing device 1 on the other side. In the combine harvester in which the grain tank 6 is provided with a discharge device in which the upper tube 12b of the discharge tube 12 rises and falls at a portion corresponding to the upper part of the grain tank 6, the discharge tube 1
A manual operating rod 19 which is parallel to the length direction of the upper tube 12b of No. 2 and which operates the upper tube 12b to raise and lower it is attached so as to be movable forward and backward, and a receiver 18 for inserting and removing the manual operating rod 19 from the lower tube 12a. Since the holder for inserting and removing the manual operation rod is attached to the lower tube, the upper tube 12b can be easily moved by pulling out the manual operation rod 19 as a handle and tilting it.
The upper cylinder 12b can be used in an upright usage position and the lower cylinder 12a is in a collapsed storage position.
Even if the work is carried out with the discharge tube 12 in the upright position, the upper tube 12b will remain connected to the lower tube by the manual operation rod 19, and the discharge tube 12 will not wobble. It is possible to perform work safely and easily while preventing accidents.
