Description

[Detailed description of the invention] The present invention relates to a reaping machine oiling device in which a horizontal conveyance chain is arranged close to the rear and upper part of the clipper-type cutting blade, and makes effective use of the arrangement of the cutting blade and chain in this type of tamp. The main objective is to simplify the structure of the oil supply device and to be able to supply lubricating oil without wasting it.

Next, embodiments of the present invention will be described in detail based on illustrative drawings.

A pulling device 1 that pulls up planted grain culms in the field, a reaping device 2 that reaps the raised grain culms, a horizontal conveyance device 3 that merges the harvested grain culms and conveys them to one side of the machine body, and a harvested grain culm. A vertical conveying device 5 receives and sends grains from a horizontal conveying device 3, and while conveying the grains backward and upward, changes its posture to a nearly horizontal posture and delivers the grain to a feed chain 4. A threshing unit 6 that performs threshing while being supported and conveyed, and a waste straw processing unit 7 that shreds the waste straw after threshing or releases it to the field without shredding, which are sequentially equipped with a crawler traveling device 8. It is connected to the machine base, so as it travels,
A 4-row combine harvester is constructed to continuously harvest and process the planted grain culms in the field.

The reaping device 2 has a movable cutting blade 9b on a fixed cutting blade 9a.
The cutting blade 9 is a so-called clipper type cutting blade 9 which is provided so as to be slidable back and forth in the lateral direction.

On the front side of the lateral conveyance device 3, four lateral conveyance chains 11 each having an endless locking pawl 10 are arranged side by side in the lateral direction, and each set of two lateral conveyance chains 11 is used to transfer the harvested grain. It is designed to transport the culm while locking the plant side.

As shown in FIG. 3, the lateral portion of each of the horizontal conveyor chains 11 is located at the rear and upper side of the cutting blade 9, and is connected to the line connecting the cutting blade 9 and the chain 11 in a side view. teeth·
゛A lubrication nozzle 12 for supplying lubricating oil is arranged on the extension line, and the lubricant jetting direction of the nozzle 12 is directed along the extension line, and the chain 1 is
The structure is such that the lubricating oil sprayed toward the chain 11 and the cutting blade 9 are sprinkled on both the chain 11 and the cutting blade 9, and the surplus lubricating oil that has passed through the chain 11 is splashed on the cutting blade 9. .

As shown in FIG. 2, the nozzles 12 are arranged in parallel at equal intervals in the lateral direction of the machine body, and are arranged so that the entire cutting blade 9 can be uniformly lubricated.

In the figure, reference numeral 13 denotes a backflow prevention plate provided close to the rear upper part of the cutting blade 9 to prevent the lubricating oil supplied to the cutting blade 9 from flowing backward and to flow down to the cutting blade 9 side. belongs to.

The present invention is not limited to combine harvesters, but can be applied to any type of reaping machine, such as a binder, in which the horizontal conveyance chain 11 is disposed close to the rear and upper side of the clipper-type cutting blade 9.

In summary, the present invention provides the above-mentioned reaper oil supply system, in which the lubricant from the lubricant nozzle 12 sprays and supplies lubricant toward the chain 11, as well as the surplus oil from the chain 11. It is characterized by being constructed so as to fall on the cutting blade 9.

In other words, in the above-mentioned type of reaper, the fact that the horizontal conveyance chain 11 is located above and behind the cutting blade 9 is effectively used.
By making the lubricating oil splashed and supplied from the nozzle 12 sprinkle on the chain 11 and the cutting blade 9, and by making the excess oil that has passed through the chain 11 sprinkle on the cutting blade 9, one nozzle 12 can Both the chain 11 and the cutting blade 9 can be lubricated, the structure of the oil supply device can be simplified, and lubricating oil can be supplied without waste.
