Description

[Detailed Description of the Invention] The present invention relates to a device for supplying lubricating oil to a reaping device for cutting the base of a planted stem culm in a reaping machine.

In order to supply lubricating oil to the reaping device as described above, it has been considered to arrange supply nozzles at appropriate intervals above the lateral end of the reaping device. Since the nozzle is installed at the top of the reaping device, it has the advantage of avoiding contact between the planted stem culm and the nozzle.Also, because the nozzle is placed at an appropriate distance above, even if mud adheres to the top of the reaping device, it can be avoided. This makes it possible to prevent this mud from coming into contact with the nozzle.

However, if the nozzle is located at the lateral end, other objects such as uncut stem culms may come into contact with the nozzle, and there is a risk that the nozzle may become clogged with straw waste or be damaged by contact with other objects. There is.

The present invention is intended to supply lubricating oil to the reaping device by arranging the nozzle in a state that takes advantage of the above-mentioned advantages, and also to solve the above-mentioned problems associated with this arrangement. A nozzle for supplying lubricating oil to a reaping device that cuts the reaping device is arranged at an appropriate interval above the lateral end of the reaping device, and the lateral outside of the nozzle is covered with a cover,
In addition, a space for removing dirt laterally and outwardly is formed below the cover.

In other words, although it can prevent contact between the planted stem culm and the nozzle and contact between the nozzle and the mud adhering to the cutting device, it also prevents the nozzle from being uncut because the cover covers the lateral outside of the nozzle. It can prevent other objects such as stem culms from coming into contact with it,
In addition, while providing the cover, it is possible to reliably discharge the mud that is being discharged laterally from the mud removal space as the reaping device operates, thereby making it possible to smoothly and efficiently supply lubricating oil to the reaping device. I ended up getting it.

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

The figure shows a combine harvester in which a reaping section is connected to the front part of the machine on which a threshing device 2, a control seat 3, etc. are mounted on a crawler traveling device 1. It is configured to carry out the reaping process as described in .

That is, the pair of left and right front lifting devices 4a and 4b
The planted stem culms of the rows are raised to an upright position, the base ends of the plants are cut by a horizontally long clipper-type reaping device 5, and the cut stem culms are conveyed to the rear threshing device 2 by a vertical conveyance mechanism 6. It is configured as follows.

Further, a reaping device lubricating device described below is configured to supply lubricating oil to the reaping device 5.

That is, as shown in FIGS. 2 and 3, lubricating oil supply nozzles 7.8 are arranged at appropriate intervals above both lateral ends of the reaping device 5, and these pair of nozzles 7.8 are arranged at appropriate intervals.
8 is connected to a hydraulic pump 9 which is placed near the control seat 3 and is driven at appropriate times.

Further, both the nozzles 7.8 have supply lowers a and 9a that spout lubricating oil downward at a steep angle, and supply lowers b that spout lubricating oil laterally.

8b, so that lubricating oil can be easily supplied throughout the reaping device 5.

Note that 10 in FIG. 1 is a lubricating oil tank connected to the hydraulic pump 9.

Further, a pair of covers 11.1 are provided on both outer sides of both nozzles 7.8 while being supported by the lifting devices 4a and 4b.
2 are provided, and these covers 11.12 cover the lateral outside of the nozzle 7.8, and the double-edged bar 1
1. ．． Below 12, there is a space A for mud removal laterally outward,
Spaces A and B are formed respectively, and the mud that is about to be discharged laterally and outwardly with the operation of the reaping device 5 is transferred to the spaces A and B.
It is now possible to discharge more.

In the embodiment, nozzles 7.8 are provided at both lateral ends of the reaping device 5.
Although the example is shown in which the holder is provided, the present proposal can also be applied to the case where the holder is provided only on one side.
