Description

[Detailed Description of the Invention] This invention relates to an improvement of a device that automatically applies lubricating oil to required parts of a working mechanism constituting an agricultural machine.

In agricultural machinery, there are operating mechanism parts that cannot be operated under oil-sealed conditions, such as the stalk culm lifting mechanism in a rice and wheat harvester, the transfer chain of a conveyance device, and the cutting blade device. By incorporating a device that automatically lubricates the operating mechanism of the machine, it is possible to make it more convenient to use.

However, existing lubrication devices either simply drip the stored oil using natural pressure to lubricate the oil, or they have a forced pressure mechanism in the oil delivery system, which sprays out lubricating oil to lubricate the oil. Therefore, although the former type has a simple structure, it has the disadvantage that the lubricating oil cannot flow out due to slight clogging of the outflow opening or bending of the oil supply path, and the latter type does not allow pressure oil to flow out. In order to send the oil, the entire oil delivery system must be strongly formed to prevent oil leakage, and it must also be equipped with a special pressurizing mechanism, which makes the entire device complicated and expensive, but neither is satisfactory. It has not been evaluated as such.

Therefore, the present invention recognizes the drawbacks of the existing equipment and is implemented in an attempt to eliminate all of the drawbacks. An easy-to-drink structure that enables smooth and reliable lubrication by providing an oil sending body with a driving body connected to the operating mechanism of the oil sending body and forcibly drawing out lubricating oil by the operation of this oil sending body. This is an embodiment of the device.

This will be explained in detail below using specific examples shown in the drawings.

The drawings illustrate the case where the device of the present invention is implemented in a combine harvester for rice and wheat, which is one of the agricultural machines.
This combine harvester C is formed by composing a reaping transport section 1, a running section 2, a threshing section 3, a steering operation section 4, and other necessary devices in a known manner.

Reference numeral A denotes a lubrication device, which is used to lubricate required parts of the operating mechanism of the combine harvester with the above structure, as necessary.The lubrication device A is constructed as described below in the present invention. .

In other words, the oil tank 6 for storing lubricating oil is installed at a higher position than the oil sending opening 7a at the tip of the oil feeding path 7, so that lubricating oil can be supplied from the opening/closing lid replenishing port 6a at the upper end. At the same time, an outlet 9 with an opening/closing knob 8 is installed and formed on the lower surface, and an oil pipe 11 is also connected to the inlet side of the distributor 10 located below the oil tank 6 to the outlet 9. connect to communicate. However, distributor 10
An appropriate number of oil pipe connection ports 12, 12, etc. are provided in the
To these oil pipe communication ports 12, 12..., oil pipes 13,
One end of each oil pipe 13 is attached, and the other end of each oil pipe 13 leads to each operating mechanism part 14, 15, . With each opening 7
An oil sending body 17 having a driving body 16 that connects the operating mechanism parts 14 and 15 is provided in part a, and when the oil sending body 17 operates, the oil flows down the oil feeding path 7 and reaches each opening 7a. The lubricating oil is forcibly drawn out in a drawn state to lubricate required parts of the operating mechanism parts 14, 15, . . . .

In the embodiment, one of the operating mechanism parts 14 and 15 is a chain with a protrusion of a stem culm lifting mechanism, and the other is a transfer chain of a stem culm transfer device. The oil sending body 17 of the oil sending path opening that leads to the required location.
is attached to a suitable fixing member 19 by means of a fitting 18, and an oil dispensing tool 20 such as a screw pump is built therein.
The shaft 21 of the shaft 21 is projected from the oil delivery port 22, and a drive body 16 is fitted into this projection, which also serves as an oil applicator 23a.
4 and 15 and rotates as these mechanisms operate, the lubricating oil is sequentially delivered from the oil delivery port 22 and applied to the operating mechanism part.

Note that the operating mechanism part in which the oil delivery bodies 17 are installed in series is not limited to a chain configuration, and may include, for example, a rotating wheel body such as a gear, other rotating parts, or a mechanical part that operates reciprocatingly such as a reciprocating type cutting blade mechanism. Of course, it is also possible to use a mechanism that performs an operating motion other than rotation, and the drive body of the oil delivery body may be directly connected to each operating mechanism, or may be configured to be involved through other required mechanisms. However, it falls within the scope of the present invention.

Furthermore, the amount of oil to be supplied to each operating mechanism is determined to be the required amount for each mechanism by appropriately setting the number of operations, the feeding pitch, etc. of the oil feeding device 20, which is comprised of a screw pump or the like, of each oil feeding body. It is also possible to use a common oil dispensing device and adopt means for adjusting the dispensing amount in other parts.

Next, to explain the operation of the device of the present invention configured as described above, lubricating oil is supplied from the supply port 6a to the oil tank 6.
If the opening/closing pot 8 of the outflow port 9 is closed, the lubricating oil will not flow down to the oil pipe 11, distributor 10, or other oil supply path.

When lubricating the operating mechanisms 14, 15..., open the opening/closing knob 8 while the operating mechanisms 14, 15... are in operation, and the lubricating oil in the oil tank 6 will flow under natural pressure. The oil flows down through the distributor 10 and down the oil pipes 13, 13, . . . to reach the respective openings 7a. Then, an oil delivery body 17 is provided in these openings, and the oil delivery device 20 is operated by a drive body 16 that operates in conjunction with the operation of the operating mechanisms 14, 15, . . . The lubricating oil is forcibly delivered from the oil delivery port 22 by the delivery tool 20, and the required parts of each operating mechanism 14, 15, . When configured to do so, the oil applicator 23a evenly applies lubricating oil to the entire chain-like operating mechanism.

As explained above, the device of the present invention has an oil feed opening 7 of a lubrication system formed in a gravity flow type.
An oil sending body 17 having a driving body 16 connected to the operating mechanism parts 14, 15, . Since the lubricating oil is forced to flow out while being drawn out from the opening 7a side, there are the following advantages.

1 In addition to the method of supplying lubricating oil by gravity, an oil delivery body with a driver is installed at the oil delivery opening, and the oil is forced to flow out at the end of the oil delivery path 7. As a result, oil can be filled properly and smoothly when required, unlike conventional equipment that uses only natural pressure to fill oil by spilling out oil, without the possibility of oil filling becoming impossible due to clogging of the opening or bending of the oil delivery route. Furthermore, since a pressurizing mechanism is not incorporated into the oil feeding path, there is no need to make the entire oil feeding path strong enough to withstand pressure oil, and the oil filling device can be made lightweight and simple.

2 Furthermore, a drive body 16 that operates the oil delivery body
When employing a configuration in which the lubricating oil is applied to the oil applicator 23a, the driving body evenly applies the spilled lubricating oil to the operating mechanism, so that it is possible to lubricate extremely well and appropriately.

3. When the oil supply system has an opening/closing mechanism for controlling lubrication (in the example, it is installed at the outlet of the oil tank), this opening/closing operation allows the lubricating oil to be released only at any time. It is convenient to use because it can lubricate the oil, and if the opening/closing cock is installed separately after the distributor's communication port, it is possible to select the lubrication cycle for each operating mechanism individually, making it convenient.
