Description

[Detailed description of the invention] The present invention provides a guide rail that contacts the chain connecting pin from the lower side in the upper path of the vertical chain and from the upper side in the horizontal or nearly horizontal lower path. Regarding the lubrication device for a stem culm conveyance chain in which rails are connected by a connecting member, the purpose is to supply lubrication to the parts of the chain that truly require lubrication by a simple and rational lubrication means that makes effective use of the original structure. It is possible to supply fuel reliably and evenly, and
Increase the degree of freedom in arranging the refueling nozzle,
The purpose is to provide advantages in terms of design and manufacturing.

Embodiments of the present invention will be described in detail below with reference to illustrative drawings.

At the front of the machine equipped with the crawler-type traveling device 1, a planted grain culm lifting device 2, a reaping device 3,
A pre-processing section 5 consisting of a harvested grain culm conveying device 4 is provided so as to be rotatable up and down around a horizontal axis, so that the cutting height can be changed. , is configured to feed the harvested grain culm from the conveying device 4 into a threshing device 6 for threshing processing, and pack the threshed grains into bags;
The waste straw carried out from the device 6 is transferred from the feed chain 7 to the waste straw conveying device 8, and is supplied to a disc-shaped cutter 9, which shreds the waste straw and discharges it to the outside of the machine. , is configured as a combine harvester for reaping and threshing grain culms while the machine is running.

The straw removal conveying device 8 is configured by a sprocket 10 that is rotatably driven around a horizontal axis via an appropriate motion mechanism, and an idler 11 that is disposed near the disc-shaped cutter 9. Wind the chain 13 vertically, and then
In the upper and lower path portions, which are approximately horizontal, the guide rails 14, 15 are connected to the pivot pins 12 from the bottom in the former and from the top in the latter, respectively.
The chain 13 is configured to rotate along a predetermined path by bringing the chains into contact with each other, and a clamping punch 16 is attached which is elastically biased toward the upper chain path portion from above to remove straw. The structure is such that the plant head side is held and conveyed, and the plant head receiving plate 17 is further configured to prevent the waste straw plant side from sagging and the straw such as the straw from falling.

A nozzle 19 provided at the tip of the oil supply pipe 18 is attached to the lower surface of the base receiving plate 17, and the structure is configured so that oil is supplied from the side toward the member 20 connecting the upper and lower guide rails 14 and 15 from the nozzle 19. At the same time, the lubricating oil from the connecting member 20 is evenly supplied to the lower chain guide 15 using the hole 21 provided below the connecting member 20, and the chain plate is connected to the chain plate from the end of the guide 15. Pivot pin 1
2 and to the sliding contact points between the chain plates.

A flow plate 22 is attached to the nozzle 19 to supply the chain guide 15 with lubricating oil dripping at the initial and final stages of oil filling.

Incidentally, the downstream plate 22 may be provided on the connecting member 20, as shown in FIG.

In summary, the present invention provides a nozzle that sprays and supplies lubricating oil toward the side surface of the connecting member in the oil supply device for the vertically rotating stem culm conveying chain described at the beginning, so that the oil received by the connecting member is released downward. It is characterized in that it is configured to feed the chain by flowing down along side rails.

In other words, by guiding oil to the chain using the guide rail connecting member and the lower guide rail,
Even though the nozzle is a spray lubrication system, it is now possible to supply lubricant evenly and without waste to the sliding contact points between the chain plates and between the plates and the connecting pins, which truly require lubricant. There are fewer restrictions on the structure, which is advantageous in terms of design and manufacturing.Furthermore, the structure can be simplified due to the effective use of the original structure.
