2. Description of the Related Art Generally, a combine provided with a Glen tank for storing paddy on one side of a fuselage has a Glen mounted at a storage position mounted on a machine stand in order to facilitate maintenance work and the like. There is known a tank in which a tank is supported to be openable and closable by a vertically rotating shaft toward a side of the body.

In such a Glen tank that can be freely opened and closed, if the lower end of the Glen tank is kept in contact with the machine base during opening and closing, it is not easy to open and close the Glen tank due to its frictional resistance. In view of this, there has been proposed an apparatus in which a roller that rolls on the machine base is provided at the lower end of a Glen tank.

However, in the case where the roller is provided at the lower end of the Glen tank, even if the Glen tank can be easily opened and closed toward the side of the fuselage, the harvesting and threshing operation is performed by setting the Glen tank to a normal storage position. When performing, the Glen tank storing the paddy will be supported only by rollers, so the load from the Glen tank will concentrate on the roller part,
For this reason, an excessive force acts on the Glen tank, causing a problem in strength.

SUMMARY OF THE INVENTION The present invention has been made in order to solve the above-mentioned problems. When the Glen tank is opened and closed, the Glen tank is supported by a rotating member and the lower end of the Glen tank is opened. Can be easily opened and closed to the side of the machine without touching the machine stand, and at the time of harvesting and threshing work where the Glen tank is in the storage position, the lower end of the grain tank storing paddy is directly attached to the machine stand. It is intended to provide a support structure of a Glen tank in a combine without exerting an excessive force on the Glen tank.

[0006]

Means for Solving the Problems In order to solve the above problems, the technical means taken by the present invention is to move a Glen tank stored on a machine base to the side of the machine body with a vertical rotation axis. In the combine which is openably and closably supported, a rotating member running on the machine base is provided at a lower end portion of the Glen tank, and the Glen tank at the time of opening and closing is supported only by the rotating member, and a traveling path of the rotating member is provided. A space where the rotating member falls into the storage position of the Glen tank is provided therein, and the lower end of the stored Glen tank abuts on the machine base. In a combine which supports a tank openable and closable to the side of the body with a vertical rotation axis, a rotating member running on the machine base is provided at a lower end of the Glen tank, and the Glen tank at the time of opening and closing is provided. Is supported only by rotating members In addition, a space is provided in the traveling path of the rotating member, where the rotating member falls in the storage position of the Glen tank, and when the paddy is stored in the stored Glen tank, the lower end of the Glen tank is moved to the machine base. It is characterized by being abutted and supported.

Therefore, according to the present invention, when the Glen tank is opened and closed, the rotating member provided at the lower end of the Glen tank runs on the machine base while supporting the Glen tank, so that the Glen tank is directed to the side of the body. It can be easily opened and closed. And when the Glen tank is in the storage position,

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the present invention will now be described in detail with reference to the attached drawings of preferred embodiments.
First, in FIG. 1, reference numeral 1 denotes a combine, and the combine 1 is a pre-processing unit 6 including a grain stem combing body 4, a weeding body 5, and the like at a front portion of an airframe 3 provided with a crawler traveling device 2. Is mounted so as to be able to move up and down, and a driving operation unit 7 and a driver's seat 8 are arranged behind the driving unit. A grain tank 9 for storing paddy after threshing and sorting is disposed on one side behind the driver's seat 8, and a threshing unit 10 is mounted on the other side of the grain tank 9.

A vertical feed pipe 11 containing a vertical feed spiral is provided upright behind the Glen tank 9, and a discharge auger 12 is mounted on the upper end of the vertical feed pipe 11 so as to be able to turn left and right and swing up and down. The paddy that has been threshed in the threshing unit 10 is sorted and then stored in the Glen tank 9,
Next, the horizontal feed spiral disposed at the bottom of the Glen tank 9 is connected to the vertical feed pipe 11 and discharged from the discharge port 12b of the discharge auger 12 to the outside of the machine.

A rotating portion 13 of the Glen tank 9 is externally fitted to the vertical feed pipe 11, and as shown in FIG. 2, the Glen tank 9 is rotated by using the vertical feed pipe 11 as a vertical rotation axis. It can be opened and closed in the direction of the arrow from the storage position on the table 14 toward the side of the body. The machine frame 14 is a machine frame 3, a machine horizontal frame 15 orthogonal to the machine frame 3,
And reinforcing frames 16, 17 and the like.

As shown in FIGS. 3 and 4, the Glen tank 9 has a bottom plate 18 and a side plate 19 which are inclined downward.
The base 14 is formed by a side plate 19 extending downward.
A lower frame body 20 is formed opposite to. Reference numeral 21 denotes a lower surface plate, and reference numeral 22 denotes a power transmission mechanism. At the lower end of the Glen tank 9, a rotating member 24 composed of a roller is turned to a corner portion 23 on the inside of the fuselage on the tip side of the rotation while slightly projecting downward from the Glen tank 9 via a fulcrum shaft 25. It is pivotally supported.

On the other hand, on the upper surface of the machine base 14, a guide plate 26 to which the rotating member 24 contacts is fixed to the machine body horizontal frame 15. The guide plate 26, the upper surface of the body frame 3 and the upper surface of the fixed frame 27 provided outside the body frame 3 form a traveling path A on which the rotating member 24 rolls. The fixed frame 27
Is to fix the Glen tank 9 by inserting the fixing pin 28 when the Glen tank 9 is in the storage position.

Therefore, when the Glen tank 9 is opened and closed, only the rotating member 24 comes into contact with the guide plate 26 and travels on the traveling path A while supporting the Glen tank 9 in a lifted state. The amount of protrusion H of the rotating member 24 is a minimum amount that can support the lower end of the Glen tank 9 in a state where the lower end of the Glen tank 9 does not come into contact with the machine base 14. The amount has become.

In the traveling path A of the guide plate 26 on which the rotating member 24 rolls, the space 2 into which the rotating member 24 falls when the Glen tank 9 is turned to the storage position.
9 are formed. That is, when the length of the guide plate 26 is set at the storage position of the Glen tank 9,
By setting the length to the front side from the position 4, the space 29 is formed below the rotating member 24, and when the Glen tank 9 is in the storage position, the rotating member 24 falls into the space 29. The lower end of the Glen tank 9 storing the paddy is directly abutted and supported on the machine base 14.

Since the present invention is constructed as described above, the harvesting and threshing operation can be carried out smoothly as in the conventional case when the Glen tank 9 is in the retracted position, and the Glen tank 9 is moved to the side of the machine body. If it is rotated, maintenance work and the like can be performed efficiently.

When the Glen tank 9 is opened and closed, the rotating member 24 rides on the guide plate 26 and travels on the traveling path A with the Glen tank 9 lifted. It can be easily turned toward. In addition, since the protrusion H of the rotating member 24 is minimized so that the lower end of the Glen tank 9 does not contact the machine base 14, the impact when the rotating member 24 rides on the guide plate 26 can be reduced. Further, since the projecting amount H is less than the total assembly amount of the components constituting the Glen tank 9, even if the rotating member 24 supports the Glen tank 9 in a lifting state, it is impossible within the range of the assembly play. It can be lifted without any action, and the operating load at the time of opening and closing can be reduced.

Next, when the Glen tank 9 is rotated and returned to the storage position, the rotating member 24 falls into the space 29 of the guide plate 26 and the lower end of the Glen tank 9 is moved to the machine base 14.
Is supported directly, so that even if paddy is stored in the Glen tank 9, the load on the Glen tank 9 can be dispersed and supported in a stable state, so that excessive force acts on the Glen tank 9. However, proper strength can be maintained.
