Description

[Detailed Description of the Invention] The present invention includes a lifting reaping section that can be raised and lowered and a control section that is equipped with a driver's seat placed side by side in front of the machine that is equipped with a traveling device. An operation box is disposed in the control section at a position closer to the raising and reaping section side than the driver's seat on the lateral side of the control section, in a manner that separates the operation section side and the raising and reaping section side. A cover body in an upright position is fixed to the lifting reaping section along the side surface of the lifting reaping section to prevent dust generated on the lifting reaping section from moving toward the control section. and furthermore,
The cover body is provided with an operating lever for a device installed in the lifting reaping section, which is movable up and down integrally with the lifting reaping section, and which can be operated in the front and back direction. This invention relates to a combine harvester in which a lever insertion hole is formed for protruding to the side.

In the combine harvester mentioned above, by installing the control section at the front of the machine in parallel with the lifting and reaping section, forward visibility is improved and the situation in which the lifting and reaping section enters the target grain culm group is improved. In addition, a cover body was provided to prevent dust generated from the lifting and reaping section from falling on workers, etc., but it had the following problems. It was hot.

In other words, the lifting reaping section is equipped with a device such as a handling depth adjustment device, and in order to provide an operating lever that can be moved back and forth for this device, the operating lever is provided at the middle portion of the cover body in the vertical direction. A lever insertion hole is opened through which the lever is inserted so that it can be moved back and forth, but forming an insertion hole in the cover body in this way reduces the shape retention strength of the cover body, so it is necessary to improve its support strength. In addition, it became necessary to increase the thickness of the cover body, which caused the problem that the overall structure became expensive. Furthermore, simply inserting the operating lever through the cover body in the upright position has the disadvantage that the lever must be bent into a complicated shape.

The technical problem to be solved by the present invention is to utilize the cover body as a means for guiding and supporting a back and forth movable operating lever for a device installed in a lifting and reaping section without reducing its shape-retaining strength. It is.

The technical means taken to solve the above technical problem is to position the cover body between the upper and lower sides as seen in the front and back direction to form a horizontal surface part, and to raise the edge of the reaping part of the cover body to form a horizontal surface part. The vertical cover portion extends upward from the control portion of the horizontal portion, and the vertical cover portion extends downward from the end of the control portion of the horizontal portion and is bent to have a crank-shaped cross section. A lever insertion hole is opened in the part, through which a back-and-forth movable operating lever for a device installed in the raising and reaping section is inserted so as to be movable back and forth.

The above technical means works as follows.

Since the cover body is constructed from a plate member having a crank-shaped cross section and having an upward vertical cover portion, a horizontal surface portion, and a downward vertical cover portion, the shape retention strength of the cover body is great. Even if the opening for the operating lever is formed in the horizontal surface portion, the shape retention strength will not be reduced.

Therefore, the present invention has the following effects.

The lever insertion hole can be opened without impairing the shape-retaining strength of the cover body, the cover body can be used as a means for guiding and supporting the operating lever, and simple structural improvements can make it more convenient to use. I ended up getting a possible combine.

Hereinafter, embodiments of the present invention will be described based on the drawings.

In front of this machine, which is equipped with a crawler traveling device 1, a threshing device 2, etc., is a pair of left and right lifting devices 3, 3 for lifting grain culms planted in the field into an upright position, and a device for cutting the base of the raised grain culms. A reaping unit 8 includes a reaping device 4 for merging the harvested grain culms, an auxiliary conveyance device 5 for merging the harvested grain culms, a rear conveyance device 7 for conveying the merging grain culms toward the threshing feed chain 6, a driver's seat 9, and a steering wheel. Box 1
The control section 11 with 0 etc. is juxtaposed.

Then, as the grain progresses, the grain culm is raised and harvested,
It is configured to automatically and continuously perform the work of sequentially handling and processing the harvested grain culms.

The pulling reaping section 8 is pivotally supported to the machine so as to be able to swing up and down about a fulcrum P, and is also supported by an elevating frame 13 which also serves as a transmission case and which can be swung by a hydraulic cylinder 12. It is constructed so that it can be raised and lowered and swung for purposes such as adjusting the cutting height, lowering it close to the ground during reaping operations, and raising it higher above the ground during non-reaping operations.

A cover body 14 is provided at the end of the lifting reaping section 8 next to the operating section 11, and is in an upright position when viewed in the front-rear direction to prevent dust from moving toward the operating section 11. This cover body 14 is formed in an inverted U-shape when viewed in the front and back direction, and covers the upper part and both lateral sides of the left and right lifting devices 3, 3.
A front end portion thereof is bolted to a lifting cover 15 bolted to the lifting frame 3, and also serves as a transmission case connecting the fulcrum portion of the lifting frame 13 and the upper part of the lifting device 3, 3. A pair of front and rear brackets 17, 17 extending from the reinforcing frame 16 of
The intermediate portion in the longitudinal direction and the rear end portion are bolted and fixed to the raising and reaping portion 8. In addition, in the figure, 18 is a horizontal cover that covers the side of the raising and reaping section 8 opposite to the side facing the control section 11, and 19 is a raising device 3.
This is an upper cover that covers the upper rear part of No. 3.

In addition, the cover body 14 has a horizontal surface portion 14a located at its upper and lower intermediate portions when viewed from the front and rear directions, and a vertical cover portion 14b extending upward from the end of the raised reaping portion 8. , the horizontal surface portion 1
The vertical cover part 14c extends downward from the end of the control part 11 of the 4a, and is made of a bent plate with a crank-shaped cross section. Front and rear movable operating lever 2 for equipment handling depth adjustment device
Lever insertion hole 21 into which 0 is inserted so as to be movable back and forth.
is opened, and a locking frame 22 for locking and holding the lever 20 at a plurality of positions in the front and rear direction is attached to this horizontal surface portion 14a.

The handling depth adjusting device changes the grain culm support position at the transport start end toward the culm by vertically swinging the rear transport device 7 and its rear end around a fulcrum Q. , the feed chain 6
The handling depth is adjusted by changing the delivery position of the grain culms to the culm direction, and two for operating the rear conveyance device installed between the elevating frame 13 and the rear conveyance device 7. The bending link mechanism 23 is configured to be operated by the operating lever 20 to bend and extend.

An operation box 24 disposed on the side of the inside of the vehicle body of the driver's seat 9 includes travel gear shift levers 25, 2.
5 is equipped.

In the embodiment, the operating lever 20 for the handling depth adjusting device is inserted through the cover body 14, but operating levers for other devices may be inserted therethrough.
