Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a system for supplying oil to the food chain of a threshing machine in which a belt transmission is installed in the lower part of the threshing feed chain.

In oil supply systems that replace conventional threshing equipment, the location of the additional oil supply nozzles was determined based on consideration to ensure that the oil supply to the feed chain could be performed well without waste. , excess oil from the nozzle is likely to be applied to the belt transmission device located at the bottom of the feed chain, causing slippage in the belt transmission device.
There is a drawback that straw debris brought into the return path of the feed chain tends to adhere to the nozzle, resulting in poor oil supply such as nozzle clogging.

The purpose of the present invention is to overcome these drawbacks by simply improving the structure by changing the nozzle setting position.

The oil supply device for a threshing machine according to the present invention, as described above, is characterized in that a oil supply nozzle is provided at a position away from the belt transmission device at the end of the return path of the feed chain.

That is, according to the present invention, since the nozzle is located away from the belt transmission, even if the chain does not receive oil from the nozzle and falls, it will not be applied to the belt transmission. In addition, lubrication with a nozzle prevents most of the straw debris brought into the return path of the chain due to chase vibrations to fall off at the end of the return path while the chain is moving in the casing. Therefore, oil supply failures such as nozzle clogging due to adhesion of brought-in straw waste can be prevented, and oil loss and oil supply failures due to oil-impregnation of brought-in straw waste can be prevented.

Generally, when refueling is performed at the end of the return path, the link plates, etc. that make up the feed chain undergo the most intense relative rotation in the movement path as the feed chain rotates from the end to the start end. Another advantage is that immediately after refueling, the oil can be applied to all parts of the feed chain.

Therefore, the present invention not only eliminates the above-mentioned conventional drawbacks through extremely simple structural improvements such as the arrangement of nozzles, but also provides a lubricating device that can efficiently lubricate the feed chain with less oil loss. I was able to do it.

In particular, when the nozzle is installed in a position to supply oil between the sprocket on the feed chain start end side and the chain section on the return path side, the sprocket can be effectively used as an oil applicator to the chain to further improve the oil supply. , the chain can be efficiently and reliably lubricated with little oil loss.

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

FIG. 1 shows a combine harvester, in which the stock base of the round culm is transported from the cutting and increasing device 6 via the conveying device 7 by the cooperation of the clamping rails 5 located opposite to each other at the top. The conveyance start end of the threshing feed chain 1, which is held and conveyed so that the tip of the shell culm moves along the inside of the handling chamber of the threshing device 8, extends diagonally downward toward the reaping device 6 side, and the feed chain 1 At the lower part of the threshing device 8, there is a winnowing shaft 9, a first grain increasing shaft 10, and a second grain increasing shaft 10.
A belt transmission device 2 is installed between the two.

In such a threshing device 8, the belt transmission device 2 is connected at the end of the return path of the feed chain 1.
A refueling nozzle 3 is connected to a refueling pump (not shown) via piping 12 at a position away from the chain in the chain movement direction.
The sprocket 4 faces between the conveyance start end side sprocket 4 of the feed chain 1 and the chain section on the return path side, and is placed in a position to supply oil to the entire width of the chain section, thereby allowing the sprocket 4 to be used as an oil applicator for the chain 1. The chain 1 is configured to be lubricated in a state where it is used for both purposes.
