DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a handle which is constructed so as to be capable of vertically swinging and opening and closing via a fixed fulcrum shaft provided on a handle room fixed frame side. In particular, the fixed fulcrum shaft and the limited space around it are effectively used to firmly support the fluffing cylinder installed upright from the handling room to the Glen tank or hopper. The present invention relates to a structure for supporting a fried cylinder in a combine.

2. Description of the Related Art Conventionally, in a combine for cutting threshed culm and threshing, a handling drum having a structure in which a number of threshing teeth are provided around a cylindrical threshing cylinder is rotated in a handling room. Although it is configured to thresh processing, when waste chips are entangled in the handling cylinder during threshing work for a long time or clogging occurs in the receiving net stretched under the handling room,
If the handling room is not disassembled, inspection and maintenance of the handling cylinder and the receiving net cannot be performed, and even after the completion of the work, the cumbersome assembly of the handling room must be performed again.

[0003] In order to solve the above-mentioned problems in performing the inspection and maintenance, the handling room is vertically divided into a vertically movable swinging room movable frame and a handling room fixed frame. There has been proposed a configuration in which a handle cylinder is rotatably supported by a user and the handling chamber movable frame body is upwardly opened during inspection and maintenance work to improve workability.

On the other hand, in a limited space between the handling room and a Glen tank or a hopper disposed on the side of the handling room, a threshing paddy taken from a lower portion of the handling room is spirally fed. A raising cylinder that rises and moves through the mechanism and discharges paddy from the top input holder to the Glen tank or hopper is erected, but as a fixed structure, the lower part is the handling room side, the upper part is the Glen tank or Since it is designed to be supported on the hopper side, the supporting structure in the upper and lower middle part is not sufficient.Especially, the above-mentioned Glen tank or hopper is configured to be rotatable and openable to the outside of the fuselage. In the combine having improved, only the lower part of the fryer is supported by the handling room side when the part is opened, and unnecessary external force is applied to the fryer when the external force is applied to the fryer. Spiral feed mechanism and connection from handling room side It had a fear of inducing damage to the mechanism.

[0005]

SUMMARY OF THE INVENTION The present invention has been made in view of the above situation, and has as its object to link a threshing operation while effectively using a limited space. Can be supported by a highly rigid structure, which complements the rigidity of each part such as the handling room, the lifting cylinder and the Glen tank, and involves vibration and resonance during threshing. Threshing and transport can be carried out efficiently without the need for inspection and maintenance of the above-mentioned parts, and it is possible to make the state in which the fryer is firmly supported on the handling room side,
An object of the present invention is to provide a support structure for a fryer cylinder in a combine which does not give an unreasonable mechanical load to a lower structure of the fryer cylinder.

[0006]

In order to solve the above-mentioned problems, the technical means adopted by the present invention is to provide an inlet side plate and an outlet side plate which are arranged side by side at a predetermined interval on the front and rear portions on the movable room side of the handling room. Between the fixed fulcrum shaft and the handle room movable frame body via a fixed fulcrum shaft. The vertical midway portion of the fryer cylinder, which is erected on one side, is fixed to the fixed fulcrum shaft via a support bracket.

In inspecting and maintaining the Glen tank 9, the Glen tank 9 is rotated outward to rotate the grain tank 10 a.
Also, when separating from the grain tank, the 10a fryer cylinder can be firmly supported on the handling room 21 side, so that the Glen tank without imposing an unreasonable mechanical burden on the lower structure of the fryer cylinder 10a. 9 inspection and maintenance work can be performed.

[0015]

In summary, according to the present invention, the handling cylinder is rotatably supported between an entrance side plate and an exit side plate arranged side by side at a predetermined interval on the front and rear portions of the handling room movable frame side. In a combine having a movable chamber frame supported on a handling room fixed frame body via a fixed fulcrum shaft so as to be able to swing up and down freely, the vertical and horizontal positions of the fryer cylinders which are located on one side of the fixed fulcrum shaft and are erected. Since the middle part was fixed to the fixed fulcrum shaft via a support bracket,
Despite its simple structure, it is possible to support a high-rigidity structure for the lifting cylinder that operates in conjunction with threshing work, and it uses a fixed fulcrum shaft that constitutes a handling room, so it has a limited space. It can be used effectively to complement the stiffness of each part, so that threshing and transport can be performed efficiently without vibration and resonance during threshing work, as well as the graining cylinder and the following Glen tank In the inspection and maintenance of the above, even when the above-mentioned parts are separated from each other, it is possible to make the state in which the fryer cylinder is firmly supported on the handling room side, so that the lower structure of the fryer cylinder is impossible. This provides a very useful novel effect that a smooth transport operation from the handling room to the Glen tank through the fryer can be easily maintained without applying a mechanical burden.
