Description

[Detailed description of the invention] The present invention relates to a lubricating oil supply device for the reaping device in a self-propelled harvester.The purpose of the invention is to have a simple structure, and evenly distribute the oil to long cutting blades on the left and right sides without any waste. The problem lies in trying to lubricate the oil without any problem.

That is, the present invention provides a pile in which an elongated oil sump is provided along the longitudinal direction of the upper part of the clipper-type cutting blade, and lubricating oil is naturally supplied to the cutting blade from multiple locations in the length direction of the oil sump. The upper end of each pipe is opened at a relatively high position within the oil reservoir.

In other words, by opening the lubricating oil gravity flow at a relatively high position in the oil sump and supplying lubricating oil to the gravity flow from the pipe as the machine rolls while traveling in the field, the structure can be manufactured easily. However, lubricating oil can be supplied evenly and in an appropriate amount from each pipe, and only when lubrication is necessary, and the above-mentioned purpose has been fully achieved.

Embodiments of the present invention will be described in detail below based on illustrative drawings.

At the front of the machine equipped with the crawler-type traveling device 1, the pre-processing section 5, which consists of a planted grain culm lifting device 2, a clipper-type cutting blade 3, and a cut grain culm conveying device 4, is rotated up and down around the horizontal axis X1. A threshing device 6 is mounted at the rear of the machine, and a feed chain 7 attached to the threshing device 6 pinches and conveys the harvested grain culm from the conveying device 4. The combine harvester is configured to carry out threshing while the machine is running, and to bag the threshed grains, thereby reaping and threshing grain culms while the machine is running.

The conveying device 4 is composed of a tip conveying device 8 and a stock conveying device 9, and this stock conveying device 9 is divided into three stages in the conveying direction, of which the middle stage is Horizontal axis X
A handling depth changing mechanism 15 is provided around 2 to be movable by driving, and to change the relay position of the harvested grain culm.

The pulling device 2 is raised to a substantially vertical position and extends high enough to allow the tip of the harvested grain culm to pass through,
These plurality of lifting devices 2... are laterally connected by a horizontal frame 10, and a lubricating oil storage tank 11 is mounted on the horizontal frame 10 at a high position, and each one is poured from the tank 11 at a high position. The oil pipe 12... is led out, and the clipper type cutting blade 3,
A stock transfer device 9 divided into three stages, a tip transfer device 8, a pivot for cutting height adjustment 13, a handling depth change mechanism 15, a feed chain 7 attached to the machine body, and each of the three lifting devices 2
. . . The lubricating oil is supplied dropwise to each of them by natural flow.

In order to lubricate the clipper-type cutting blade 3, lubricating oil is supplied from the tank 1 through the relay pipe 16 to a long and thin oil reservoir 14 attached along its longitudinal direction. A plurality of pipes 17 are attached in a state where they are distributed in the length direction, and the upper openings 17a of each of the pipes 17 are provided at a relatively high position within the oil sump 14. The lower end side is supported by the cutting blade cover 3a near the cutting blade 3, and the lubricating oil in the oil sump 14 overflows into the pipe 17 by the rolling of the machine during harvesting, and the lubricating oil is transferred to the cutting blade 3. The lubricating oil is configured to be supplied by gravity in a distributed state in the longitudinal direction.

As shown in FIG. 2, the tank 11 has an oil chamber a1 which horizontally partitions the inside of a tank body made of translucent synthetic resin with vertical partitioning walls 11a and communicates with each other at the upper part thereof.
, a2, .

The cross-sectional area of each oil chamber a1 is determined such that, for example, the oil chamber a1 for the cutting blade 3 is large, and the oil chamber an for the cutting height adjustment pivot portion 13 is large.
are set depending on the required amount of lubricating oil, such as making it smaller.

A closing member 19 for the bottom opening a' of each oil chamber a is provided so as to be movable up and down by rotating a knob 20, so that oil supply can be stopped.

It would be convenient if the opening position of the pipe 17 in the oil sump 14 could be changed, so that unevenness in the amount of oil to be filled due to rolling of the aircraft body could be corrected.

In addition, by setting the opening positions of the pipes 17 at the center of the fuselage lower than those at both left and right ends, it is advisable to take care to sufficiently lubricate the center position, which is less affected by rolling. .
