Abstract

PURPOSE:To facilitate the work such as the maintenance and inspection of a grain tank by placing a volume-increasing tank at the outside of a grain tank and providing the increasing tank with a means to pull and swing the tank outward around its lower end and with a means to swing and open the tank around its upper end. CONSTITUTION:A grain tank 2 for holding threshed grains is placed at a side of a thresher 1 mounted on a machine body of a combine. An exterior side part of the grain tank 2 is opened and a volume-increasing tank 3 is attached to the opened part. When the grain tank 2 is charged almost fully with grains, the volume-increasing tank 3 is pulled outward and tilted around a supporting point P1 by the aid of a hinge 4 attached to the lower end of the tank 3. The volume of the grain tank 2 can be increased by this procedure. In the case of the maintenance, inspection, etc., of the grain tank 2, the hinge 4 is removed, the volume-increasing tank 3 is lifted outward around a connection pin 6 positioned at the upper end of the tank and supported with a supporting lever 9 and the lateral side part of the grain tank 2 is opened for the maintenance, etc.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a grain tank for storing grain after threshing, which is disposed on the side of a threshing machine.

[Prior art and problems]

Conventionally, when opening the outer side of the grain tank, the increase tank was configured to swing open outward and downward using its lower end as a rotational fulcrum. Therefore, the increase tank became an obstacle and it was difficult to enter the grain tank, making maintenance work such as 1 inspection difficult.

In order to solve this problem, the present invention is designed to normally take in and take out the expansion tank using the lower end as a fulcrum, but when opening the tank, it swings outward and upward using the upper end as a fulcrum.

[Means to solve the problem]

In other words, one technical means according to the present invention is a means for reversibly pulling out and swinging a bulking tank provided on the outside of a grain tank that accommodates threshed grains outward using its lower end as a fulcrum; The device is characterized in that it is provided with means for swinging open/close using the upper end side of the increase tank as a fulcrum.

[Operation and effect of the invention]

Therefore, according to the present invention, the substantial capacity of the grain tank can be increased by pulling out and swinging the increase tank outward using the lower end side as a fulcrum, and conversely, by putting it in and rocking it, Although it can be stored in a state that does not significantly affect the storage function of the tank, especially in the present invention, since the increase tank is configured to be able to swing open and close using one end as a fulcrum, it is possible to store the tank without significantly affecting the storage function of the tank. When opening the outside side, the tank can be opened by lifting the tank upwards to the outside and swinging it, which has the advantage of making it easy to get in and out of the tank and making maintenance and inspections easier. .

〔Example〕

An embodiment of the present invention will be described below based on the drawings.

A grain tank 2 for storing grains after threshing is mounted on the side of a thresher 1 mounted on the body of the combine. Open the side outer part of Glen Tank 2.

In the open part, a lateral outer plate 3a and an anteroposterior side plate 3b-
30 is provided, and a hinge 4 is provided so that the increase tank 3 swings with its lower end as a fulcrum P.
are connected via. Reference numeral 5 denotes a lid plate that covers one side of the increase tank 3, and is rotatably connected to the tank body 2 and the upper end of the lateral outer plate 3a via a connecting pin 6. It is configured to be bendable via a connecting pin 8.

And the increase tank 3 configured in this way is as follows.

Remove the hinge 4 from the tank body 2 while pulling it out and swinging it laterally outward with the lower end as the fulcrum P, and use the upper end as the fulcrum P3.

It is configured to be lifted and swung outwardly and upwardly about the connecting pin 6, held in this state by the support rod 9, and to open the lateral outer portion of the tank body.

In the figure, 10 indicates a discharge screw conveyor provided at the bottom of the tank, and 11 indicates an inspection window.

[Brief explanation of drawings]

The figures show one embodiment of the present invention, and FIGS. 1 and 2 are longitudinal sectional rear views of the grain tank, and FIG. 3 is a side view of FIG. 1. 2 is a grain tank, 3 is an increase tank, p,,p. indicates the pivot point.

Claims (1)

[Claims] (1) A means for reversibly pulling out and swinging an increasing tank provided on the outside of a grain tank that accommodates threshed grains outward using its lower end as a fulcrum; A grain tank characterized in that it is equipped with means for swinging open and close as a fulcrum.
