DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a grain collecting position stored on a frame of a threshing machine by supporting a Glen tank juxtaposed on the lateral outer side of the threshing device so as to be pivotable about a vertical axis. A combine tank support structure of a combine, which is configured to be switchable to a maintenance position that protrudes outward on the lateral side of the fuselage frame, and is provided at a lower end portion of the Glen tank with a support fitting for riding on the fuselage frame. About.

[0002]

2. Description of the Related Art Conventionally, as shown in Japanese Utility Model Laid-Open Publication No. 2-93936, the above-described grain tank support structure of a combine is formed by simply forming the upper surface of a body frame on which the support bracket rides on a flattened plane, and Along with the swinging swing of the surrounding Glen tank, a U-shaped leg for sliding and moving on the body frame while supporting the Glen tank is protruded downward at the lower end of the support bracket, A lock pin type lock mechanism for locking the Glen tank with respect to the machine body at the grain collection position is provided.

[0003]

However, according to the above structure, the Glen tank is slid on the body frame while being supported by the U-shaped legs in accordance with the swing swing of the Glen tank around the longitudinal axis. Was configured as
The character-shaped legs receive frictional resistance from the fuselage frame, so that a large force is required for swinging and swinging, resulting in a problem that the work is troublesome. In order to solve this problem, it is conceivable to provide a roller capable of rolling on the body frame in place of the U-shaped leg on the support bracket, but with such a configuration,
During the grain collection at the grain collection position, the load is repeatedly applied to the lock pin as the body fluctuates, so that, for example, the lock pin may be bent or broken.

[0004] It is an object of the present invention to be able to swing and swing the Glen tank around the vertical axis with a small force, and to reliably fix the Glen tank to the body frame at the grain collection position, thereby performing the grain collection operation. An object of the present invention is to provide a stable Glen tank support structure for a combine.

[0005]

According to a feature of the present invention, a rail extending in the width direction of the Glen tank is provided at the bottom of the support bracket, and the Glen tank rotates and swings around a vertical axis. A roller that idles while placing and supporting the rail portion is provided at the lateral outer end of the body frame,
With the Glen tank positioned at the grain collection position,
A concave portion for receiving the roller is formed on the rail portion side so that the rail portion is supported by the body frame in a surface contact state.

[0006] A lock mechanism for locking the rail portion and the machine frame may be provided. In addition, when the Glen tank is positioned at the grain collecting position, a concave portion on the rail portion side is provided. An elastic portion for elastically fitting the roller to the opening may be provided on the outer peripheral portion of the roller.

[0007]

According to the above construction, when the Glen tank is pushed inward from the maintenance position around the longitudinal axis toward the inboard side of the fuselage, the rail provided on the bottom of the support bracket is moved outwardly of the inboard side of the fuselage frame. The roller rides on a roller provided at the end of the roller and swings while being rolled and supported by the roller. When the grain tank is located at the grain collecting position, the roller enters the recess formed on the rail portion side, and the rail portion is supported by the machine body frame in a surface contact state. As a result, even if the aircraft shakes during grain collection at the grain collection position, the friction force between the surfaces between the rails and the body frame makes it difficult for the Glen tank to be displaced, and the Glen tank is Securely fixed to the frame.

On the other hand, when the Glen tank is pulled from the grain collection position to the outside of the machine lateral side around the longitudinal axis, the rail portion on the machine lateral side inward side of the roller rides on the roller again, and The swivel swings while being supported by the rolling, and the Glen tank is located at the maintenance position.

In the case where a lock mechanism for locking the rail portion and the body frame is provided, not only can the Glen tank be securely fixed by the body frame, but also the rail portion and the body portion which are in surface contact and are relatively difficult to move. By providing a lock mechanism between the frame and the frame, for example, a load applied to the lock mechanism can be reduced as compared with a case where a lock mechanism is provided between the upper portion of the Glen tank and the body frame, and the like. Damage can be prevented.

In a case where an elastic portion for elastically fitting the roller to the opening of the concave portion on the rail portion side is provided on the outer peripheral portion of the roller in a state where the Glen tank is located at the grain collecting position. By elastically fitting the elastic portion of the roller to the opening of the concave portion, the Glen tank can be reliably positioned at the grain collecting position, and the vibration of the Glen tank can be prevented.

[0011]

Therefore, since the grain tank is swiveled on the body frame via the rollers, the grain tank can be swung and swung around the longitudinal axis with a small force, and at the grain collecting position, the grain tank is moved to the body frame. A combined grain tank support structure that can be fixed securely and can stably perform a grain collection operation can be provided.

In the case where a lock mechanism for locking the rail portion and the machine frame is provided, the Glen tank can be securely fixed by the machine frame, and the load applied to the lock mechanism can be reduced, so that the lock mechanism can be reduced. Damage can be prevented, and an elastic portion for elastically fitting the roller to the opening of the concave portion on the rail portion side is provided on the outer peripheral portion of the roller while the Glen tank is located at the grain collection position. When configured, the grain tank can be reliably positioned at the grain collection position, and the vibration of the grain tank can be prevented, so that in any case, the grain collection work can be performed more stably. A combine tank support structure could be provided.
