JPH0549330A - Oil tank holder of combine - Google Patents

Abstract

PURPOSE:To shorten pipes, etc., and to facilitate the maintenance by placing an oil tank and an oil-hydraulic valve of a combine respectively at positions close to the engine, the transmission gear, etc., but not getting in the way. CONSTITUTION:This oil tank holder of a combine has a structure where an oil tank 5 and an oil-hydraulic valve 6 are arranged respectively at a lower part and an upper part in a step chamber 4 formed under the control step 3 between the driver's seat 1 and the controlling platform 2 at the front end part of the car body.

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a combine oil tank supporting device.

[0002]

2. Description of the Related Art In combine harvesters, since a harvesting device that moves up and down with respect to a vehicle body is provided in front of the combine vehicle, a cockpit is also provided in the front portion of the vehicle body to facilitate the operation. Many. However, raising and lowering the reaper,
A hydraulic device is often provided as a drive transmission and various control devices. In this case, a large installation location is required for an oil tank for hydraulic pressure and a hydraulic valve, and the configuration is likely to be complicated. The present invention simplifies the mounting structure of such an oil tank, hydraulic valve, etc., and installs them in a position where they do not easily get in the way.

[0003]

According to the present invention, an oil tank 5 is provided at a lower portion in a step chamber 4 formed under a control step 3 between a control seat 1 and a control base 2 at a front end of a vehicle body.
A combine oil tank supporting device having a hydraulic valve 6 disposed at the upper portion is configured.

[0004]

Since the hydraulic valve 6 and the oil tank 5 are provided in the step chamber 4 under the control step 3, even if they are close to the transmission device or the engine of the lateral side or the rear side, These are less likely to get in the way, the width of the step chamber 4 can be sufficiently secured, and the piping path such as the hydraulic hose can be shortened. Further, since the hydraulic valve 6 is located above the oil tank 5, maintenance is possible. Is also easy.

DESCRIPTION OF THE PREFERRED EMBODIMENTS A pair of left and right traveling devices 8 in the form of crawlers are driven and rotated by a drive sprocket 9 at a front end portion under a frame 7 of a combine. On the frame 7,
A threshing device 10 for threshing while transferring the harvested culm from the front to the rear, a control stand 2, a control step 3, an engine 11, a paddy accommodating hopper 12, and the like are provided, and the harvesting device 13 is directed forward from the frame 7. Is supported. This reaper 1
The mowing frame 18 of No. 3 has a grain culm raising device 14, a cutting blade device 16, a mowing grain culm transfer device 15, and the like, and is configured to be able to be lifted and lowered by expanding and contracting a hydraulic cylinder 19 with respect to the frame 7. A feed chain 17 is stretched in the front-rear direction along one side of the threshing device 10.

The cockpit 1 is provided in a front portion of one side of the frame 7, an engine 11 is provided in a lower side thereof, and is mounted on an upper portion of an engine cover 20 which covers the engine 11. The operation step 3 and the operation platform 2 etc. are integrally configured and have a pair of left and right step frames 21, which can be connected by detachably attaching to the front end of the frame 7. Reference numeral 22 denotes a step cover that surrounds the periphery, and together with the upper operation step 3 and the like, forms a step chamber 4 on the lower surface of the operation step 3 as wide as possible.

Two upper and lower steps 23 are mounted on the outside of the step frame 21, and an oil tank 5 and a hydraulic valve 6 mounted on the upper surface of the oil tank 5 are housed in the step chamber 4. Set up. The reference numeral 24 designates the mounting bolts which are detachable. The control platform 2 is formed in a hook shape in a plan view over the front side of the control step 3 and the mowing device 13 side, and is provided with an operating mechanism for performing various operations such as the traveling device 8 and the mowing device 13. Reference numeral 25 denotes a control lever, which turns to the left and right to perform steering, and turns to the front and back to raise and lower the reaping device 13. 26 is a vehicle speed lever, 27 is a reaping clutch lever, and 28 is an operating lever of each threshing part.

A hydraulic pump 29 is provided in the body of the engine 11, and a transmission for transmitting the drive sprocket 9 of the traveling device 8 has a hydraulic continuously variable transmission HST as a main transmission.
The oil in the oil tank 5 is partially transferred to the hydraulic continuously variable transmission HST by the hydraulic pump 29.
The pipes are configured so as to be supplied to the hydraulic cylinder 19 for raising and lowering the mowing and a part thereof.

The removable hydraulic valve 6 on the lid 30 of the oil tank 5 comprises a solenoid valve 31, a manual spool valve 32, etc. on the upper surface thereof, and a tank port T thereof.
Is communicated with the oil tank 5 by a return pipe 33. In addition, the hydraulic continuously variable transmission H is provided at the bottom of the oil tank 5.
A feed pipe 34 and a return pipe 35 for supplying to the ST,
Further, a feed pipe 36 and the like for supplying the hydraulic valve 6 are provided.

In the hydraulic continuously variable transmission HST, replenishment oil is constantly supplied from the hydraulic pump 29 and is supplied from the feed pipe 35 to the charge pump. Oil is supplied to the hydraulic cylinder 19 and the like from the feed pipe 36 by the hydraulic pump 29 via the hydraulic valve 6.
In addition, the oil in the oil tank 5 may be once returned through the oil cooler.
