DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a bagging work section for a combine, and more particularly to an improvement in means for maintaining an upright storage position of an auxiliary deck.

[0002]

2. Description of the Related Art Conventionally, a bagging operation section for bagging and collecting grains transported from a threshing apparatus is provided with an auxiliary deck on which an operator is to board and a full bag is placed, on the lateral side of the machine. It is provided on the outer edge of the main unit side deck so as to be freely swingable between a protruding posture and a standing storage posture, for example, as shown in Japanese Utility Model Laid-Open No. 2-12232, Attached freely to the bearing, and configured to maintain the auxiliary deck in a protruding position or an upright retracted position by the action of a tension spring that swings beyond the dead point, or Japanese Utility Model Laid-Open No. 60-182739. As shown in (1), the auxiliary deck is mounted so that it can only swing with a hinge, and the auxiliary deck is maintained in a protruding position or an upright storage position by a lock device.

[0003]

However, in the former prior art, the tension spring cannot be made too strong in order to facilitate the switching operation of the auxiliary deck, and the auxiliary deck in the upright storage position cannot be used due to body vibration or the like. There is a risk of accidentally descending and swinging to the overhanging posture, and in the latter conventional technology, the operation of changing the position of the auxiliary deck is easily troublesome due to the lock device, and in short, any of the conventional technologies raises the auxiliary deck It was difficult to achieve both the reliability of maintaining the storage posture and the simplicity of the posture switching operation, and further improvement was required.
An object of the present invention is to make it easy and quick to change the position of the auxiliary deck, and to ensure that the standing position of the auxiliary deck can be stably stored. There is a point to devise.

[0004]

The feature of the present invention is to provide a bagging hopper for storing grains transported from a threshing device, and to provide a projecting posture, a standing posture and a standing posture which protrude laterally outward of the fuselage. In the combine in which the auxiliary deck is attached to the main deck on the main unit side so as to freely swing, a slit opened downward is formed in the deck surface of the main deck along the outer edge of the main deck. At the longitudinal end of the slit, a bearing is provided for supporting a rotation support shaft provided at both ends of the base of the auxiliary deck, and the base of the auxiliary deck in the upright storage posture can enter the slit. And the bearing is configured to allow the rotation of the rotation support shaft as the auxiliary deck changes its posture between the overhanging posture and the standing storage posture, and the vertical movement of the rotation support shaft within a predetermined range. The base of the auxiliary deck, which stands up with the change in posture from the overhanging posture to the upright storage posture, can be dropped below the upper surface of the main deck together with the rotation support shaft. It is in.

[0005]

[Function] In other words, the auxiliary support deck is attached to the bearing so that it can rotate and move up and down freely, and after the auxiliary deck is raised and swung from the overhanging posture, the auxiliary deck is dropped into the slit. The auxiliary deck can be maintained in the upright storage position, and the auxiliary deck can be switched from the upright storage position to the overhanging position simply by swinging the auxiliary deck outward after lifting the auxiliary deck from the slit. With this configuration, the operation of changing the position of the auxiliary deck can be easily and quickly performed. As a configuration for supporting the auxiliary deck by changing its posture between a protruding posture and an upright storage posture, a slit formed in the main deck and a slot-shaped bearing portion provided at both ends thereof are provided. By adopting a slit formed in the main deck as a component, the main deck itself can be used as a part of the support means of the auxiliary deck, and a strong support means can be achieved with a simple structure. In addition, since the slit is opened downward, there is no possibility that dust or the like is clogged in the slit and it becomes difficult to drop the auxiliary deck.

[0006]

As a result, the operation of changing the position of the auxiliary deck can be performed easily and quickly, and the support means for changing the position of the auxiliary deck can be constructed with a strong and simple structure. In addition, the presence of the slit used as the support structure makes it easy to easily drop and discharge dust on the main deck and the auxiliary deck while using the main deck itself as a support means.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS As shown in FIGS. 1 to 3, a mowing unit 2 is connected to the front of a traveling vehicle equipped with a crawler type traveling device 1, and a threshing device 3 and a driving unit 4 are mounted on the traveling vehicle. In addition, a bag-packing work unit S is installed on the side of the threshing device 3 and behind the driving unit 4 to constitute a self-removing combine. In the bagging work section S, a bagging hopper 6 for storing the collected grains from the main deck 5 and the threshing device 3,
A bag support rod 8 for suspending and supporting the grain bag 7, an auxiliary deck 9 which can be moved back and forth, and the like are provided.

As shown in FIG. 2, the auxiliary deck 9 has an arched peripheral frame 9b made of a round pipe connected and fixed near the front and rear ends of a base frame 9a made of a straight circular pipe. 9a and the front and rear middle part of the peripheral frame portion 9b are stays 9c.
And a step plate 9d is attached over the base frame 9a and the peripheral frame portion 9b. The front and rear ends of the base frame 9a protrude to form a rotation support shaft 9e for reciprocating rotation. It is.

Near the outer edge of the main deck 5, a pair of left and right frames 5a and 5b are arranged in parallel.
A slit 10 is formed between a and 5b. The slit 10 is long and open to the front and back so that the base end of the upright auxiliary deck 9 can be dropped. At the front and rear ends of the slit 10, a pair of upper and lower bearings 11a and 11b are
a, a bearing hole 12 which is attached over the 5b and has a vertically long hole shape.
Are formed, and the rotation support shafts 9e of the front and rear of the auxiliary deck 9 are respectively engaged and supported in the front and rear bearing holes 12.

According to the above structure, the auxiliary deck 9 is pulled up and turned laterally outward until the rotation support shaft 9e reaches the upper end of the bearing hole 12, so that as shown in FIG.
Is received on the frame 5b of the main deck 5, and is held in a protruding posture protruding laterally outward of the fuselage. Further, the auxiliary deck 9 can be held in the upright storage position by temporarily swinging up and down from the overhanging position. In this case, the slit 10 is
The auxiliary deck 9 which has been dropped into contact with the frames 5a and 5b serving as the left and right side walls of the slit 10 is held in the upright storage position.

[Alternative Embodiment] In the above-described embodiment, the rotary support shafts 9e are formed at both ends of the base frame 9a made of a round pipe constituting the frame of the auxiliary deck 9, but a solid rotary support manufactured separately. The shaft 9e may be provided before and after the base of the auxiliary deck 9 for implementation.

In the claims, reference numerals are provided for convenience of comparison with the drawings, but the present invention is not limited to the configuration shown in the accompanying drawings.
