Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a grain storage device for combine harvesters.

[0002]

2. Description of the Related Art Conventionally, in a combine, a traveling device is provided below the machine base, a threshing device is provided on one side above the machine base, and a grain storage device is provided on the other side above the machine body. Are configured. Further, a control unit, a prime mover and the like are further provided on the machine base. Some of the grain storage devices are configured to be movable to the outside of the machine body for maintenance of the grain storage device itself and a portion hidden by the grain storage device. The configuration for moving the grain storage device to the outer side of the fuselage includes the one that has a vertical axis fulcrum at one front and rear end of the grain storage device and is capable of rotating in the lateral direction, a guide rail, etc. There is a configuration in which the grain storage device is slid laterally while being parallel to the threshing device.

Of course, there is also provided a locking device for locking the grain storage device in the state of being housed in the machine body. When moving the grain storage device, the locking by the locking device is released, and then the grain storage device is pulled out to the outside of the machine body.

[0004]

As described above, the grain storage device configured to be movable to the outside of the machine is provided with the locking device for locking the grain storage device in the state of being stored on the machine side. is necessary. Also, when locking the grain storage device to the fuselage side,
If this locking is performed at only one place, the locking rigidity of the grain storage device will be low, and the stability will be lacked, such as swaying when the machine is running. That is, a plurality of locking devices are required at appropriate intervals between the grain storage device and the machine body side.

However, as described above, when the locking devices are provided at a plurality of positions with appropriate intervals, the unlocking operation of these locking devices is performed individually before moving the grain storage device. It has to be done and is annoying. After releasing these locks, a part of the grain storage device is grasped and pulled out to the outside. As a result, finally, the grain storage device itself and the portion hidden by the grain storage device can be maintained.

As described above, in the prior art, a complicated operation is required to move the grain storage device outward, resulting in a reduction in work efficiency.

[0007]

In order to solve the above-mentioned problems, the present invention takes the following technical means.
That is, in a combine machine in which a traveling device 2 is provided below the machine base 1, a threshing device 3 is provided on one side above the machine base 1, and a grain storage device 4 is provided on the other side above the machine body 5, A member configured to move the grain storage device 4 to the outside of the machine body 5 and lock the grain storage device 4 to the machine base 1 in a state where the grain storage device 4 is stored to the inside of the machine body 5. A grasping part / release operation tool 8 is provided which is provided with a stopping device 6 and a locking device 7 for locking the threshing device 3, and which can cause the locking device 6 and the locking device 7 to release the cooperation. The locking device 6 and the locking device 7 are released by being attached to the grain storage device 4 side and pulling the gripping part / release operation tool 8 outward of the machine body 5. Then, the grain storage device 4 is configured to be pulled out to the outside of the machine body 5. It is obtained by the structure of grain storage apparatus Combine characterized by.

[0008]

[Advantageous Effects of the Invention] Grains are harvested while the combine is running, and the harvested grains are put into the grain storage device 4 equipped in the combine body 5 and temporarily stored. The stored grains can be discharged as needed. Maintenance of the grain storage device 4 itself, or the grain storage device 4
When performing maintenance or the like on the periphery, for example, the transmission mechanism of the inner surface of the threshing device 3 hidden by the grain storage device 4, it is necessary to move the grain storage device 4 to the outside of the machine body 5.

At this time, the operator first grips the gripper / release operation tool 8 attached to the grain storage device 4 side, and pulls it toward the outside of the machine body 5. As a result, first, the locking device 6 and the locking device 7 are both released and actuated to lock the grain storage device 4 and the machine base 1, and the grain storage device 4 and the threshing device 3. Both the locked state of and are released.

When the gripper / release operation tool 8 is further pulled outward, the grain storage device 4 integrated with the gripper / release operation tool 8 is taken out to the outside of the machine body 5. . As a result, the grain storage device 4 moves to the outside of the machine body 5 and the maintenance can be easily performed. . In this way, the grain storage device 4 is attached to the body 5
The work of moving it to the outside becomes very easy, and the work efficiency can be dramatically improved.

A grain discharge auger 36 is provided above the fixed metal 34 by a motor 37 so as to be rotatable and a hydraulic cylinder 38 so as to be vertically rotatable. The upper portion of the fried grain portion 39 of the grain discharging ogre 36 is rotatably supported by the rotation supporting station 40 integrated with the upper portion of the support frame 29.

Further, an L-shaped downward bending lever-shaped grasping portion / releasing operation tool 8 is axially attached to a lower position on the outer side surface of the front side wall 16 of the grain storage device 4 by a shaft 41 in the front-rear direction. Further, at the upper front end of the inner wall 14 of the grain storage device 4,
A hook 44 for locking is pivotally attached by a winding spring to a downwardly biased state via a station 43 having an engagement guide member 42.

The elongated hole at the lower end of the interlocking rod 46 is axially engaged with the tip of the inwardly projecting arm 45 of the gripper / release operation tool 8, and the upper end of the interlocking rod 46 is connected to the hook 44. It is pivotally attached to the arm portion 47. On the other hand, an engaging portion 4 with which the hook 44 is engaged is provided at an intermediate portion of the front frame 25.
8 is provided. With this configuration, at the storage position of the grain storage device 4, the hook 44 engages with the engaging portion 48 so that the upper portion of the grain storage device 4 is locked to the machine body 5 and is moved laterally. It will be fixed. This is the locking device 7.

Further, a U-shaped support station 49 is attached to the lower end of the front side wall 16 of the grain storage device 4 in a vertical posture. The support station 49 has holes in the upper end surface and the lower end surface, and the fixing pin 50 which is elongated in the vertical direction is formed in the holes.
To be slidable in the vertical direction. An upper end portion of the fixing pin 50 has an outer protruding arm 51 of the grip portion / release operation tool 8.
The shaft is attached to the middle part of. A large diameter portion is formed in the lower portion of the fixing pin 50, and a push spring 52 is arranged between the large diameter portion and the upper end surface portion of the support station 49. The fixing pin 50 is always urged to slide downward by the push spring 52, whereby the sharpened lower end of the fixing pin 50 is provided on the machine base 1 at the storage position of the grain storage device 4. It is fitted into the joint hole 53. by this,
The lower part of the grain storage device 4 is locked to the machine body 5 and fixed in the lateral movement. This is the locking device 6.

An engaging claw 54 projecting forward is provided at the lower end of the front side wall 16 of the grain storage device 4, while the engaging claw 54 is fitted from the outside on the upper surface of the machine base 1.
