Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a combine dustproof cover device, which is used for a self-removing combine.

[0002]

2. Description of the Related Art A conventional combine dustproof cover device, for example, a structure disclosed in Japanese Utility Model Publication No. Sho 56-170935 is one in which a dustproof cover is provided above a front grain culm conveying passage of a thresher. Is publicly known. According to this structure, the dust-proof cover is located above the culm transport passage during the mowing and threshing work, and exhibits its original dust-proofing effect, and can be lowered to be used as a rice paddle when handling pillows. It was

In the construction disclosed in Japanese Utility Model Laid-Open No. 56-153139, a cover is attached to the upper part of the grain culvert transporting device by a hinge so as to be freely opened and closed.

[0004]

The dust-proof cover device provided on the combine culm conveyer device is required to be manufactured at low cost in addition to ensuring its strength. In addition, the cover device is capable of reliably exerting a dustproof function during transportation of the grain culverts so as not to obstruct the field of view of the operator, and at the same time, it is necessary that the cover device be in a low position. Of course, it is necessary to have a structure that can be retracted to a lower position even when opened.

[0005]

The present invention takes the following technical means in order to achieve the above object. That is, a thresher 3 is mounted on a chassis 2 having a traveling device 1, and a grain culm transporting device 4 and a cockpit 5 are provided side by side in front of the threshing mill 3, and the grain culm transporting device 4 A cutting device 6 is provided at a lower front position, and a dust-proof cover 7 supported by a side cockpit 5 is provided in front of the threshing machine 3 and above the grain culm conveying device 4,
The dust-proof cover 7 has a front fixed portion 7a and a rear open portion 7b.
The open portion 7b is a combine dustproof cover device that can be superposed on the upper side of the fixed portion 7a when moved forward.

[0006]

EXAMPLE First, the structure will be described. The combine comprises a threshing machine 3 mounted on a chassis 2 having a traveling device 1, and a harvesting and conveying frame 8 composed of a harvesting device 6 and a grain culm transporting device 4 provided on the front side thereof so as to be vertically rotatable. .

Reference numeral 9 indicates a grass body, and 10 indicates a grain culm raising device. The cockpit 5 is provided at the side of the grain culm transporting device 4 that constitutes the harvesting transport frame 8. The mounting substrate 11 is
Attached to the side frame of the cockpit 5 in the front-back direction,
A fixed portion 7a at the front of the dustproof cover 7 is attached to the support frame 12 provided at the front.

The supporting arms 13 and 13 'are provided on the mounting base 11
The base portion is pivotally attached to the mounting shafts 14 and 14 ′ that are provided to extend laterally from, and the open portion 7 a of the dustproof cover 7 is mounted to the tip end portion through the mounting frame 15. And the open portion 7a
Is located above the grain culm transporting device 4 and in a position where the rear part of the fixing part 7a continues to exhibit a dustproof function, the rear part is supported while being supported on the receiving frame 16.

The receiving frame 16 has one end supported by the mounting portion 17 of the mounting base 11 and the other end supported by the machine frame of the threshing machine 3. The support arms 13 and 13 'described above have one end (front side) shorter than the other end (rear side), and when the open portion 7b is moved forward, the support arms 13 and 13' are sequentially moved to the forward tilted state and the fixed portion 7a. It is configured to overlap the upper side of.

Reference numeral 18 is a Glen tank, and 19 is a discharge auger.
Indicates. Next, the operation will be described. First, work is started while driving each part. When the vehicle platform 2 is propelled by the traveling device 1, the grain culms in the field are weeded by the front weeders 9 for each grain culm row, reach the grain culvert raising device 10, and are subjected to the raising action.

Then, the grain culm reaches the reaping device 4 and is mowed, and at the same time, the grain culm is clamped by the grain culm conveying device 4 and conveyed sequentially rearward to be supplied to the threshing machine 3 to undergo threshing treatment. During such an operation, the dust-proof cover 7 can reliably prevent dust generated from the grain culms being held and conveyed by the lower grain culm transporting device 4 without scattering to the outside.

During such a series of operations, the dust-proof cover 7 is securely attached to the attachment base material 11 provided on the side portion of the cockpit 5 via each attachment member, so that the chassis 2 vibrates. Even if it doesn't break, it doesn't get out of order and can withstand long-term use. Next, the dustproof cover 7 is
The case of opening the grain culm transporting device 4 for maintenance such as cleaning will be described.

That is, the open portion 7b has the support arms 13, 1
As shown in FIG. 2, 3'is swung forward and moved above the fixed portion 7a. Then, the grain culm transporting device 4 can be opened to remove the entangled straw and the like. The combine is capable of traveling safely without blocking the forward view of the open portion 7b even when the open portion 7b is moved forward and moved forward in the open state as described above.

[0014]

As described above, in the dustproof cover device according to the present invention, the front portion is fixed and only the rear portion is opened, so that only the necessary portion can be opened and the supporting structure can be simplified. Moreover, there is also a feature that it can be firmly supported by a supporting device provided on the cockpit side. Further, since the open portion does not move upward even in the open state and moves to a relatively low position in front, it has a feature that it can travel safely even in the open state without obstructing the forward field of view.
