Description

[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION The present invention relates to a harvesting and harvesting system in which a raising chain wound around an upper sprocket and a lower roller is provided in a raising case having an inclined posture, and lubricating means for supplying lubricating oil to the raising chain is provided. The present invention relates to a stem and stem raising device.

[0002]

2. Description of the Related Art Conventionally, as the lubricating means, for example, as shown in Japanese Utility Model Application Laid-Open No. 64-13928, lubricating oil is once supplied dropwise to a lower roller, and the lubricating oil is raised from the lower roller to supply lubricating oil to a chain. It was configured to supply adhesion.

[0003]

[Problems to be solved by the invention] However, the straw and soil in the raised case tend to collect around the lower roller,
There is a possibility that the supply of lubricating oil may be hindered by the accumulated straw or soil, and there is room for improvement in lubricating oil supply performance. To solve such a problem, it is conceivable to lubricate the upper sprocket in the raising case, but the upper sprocket has a chain wound on the upper half side,
Since the raised claw is attached to this, if you try to lubricate the sprocket and chain with the nozzle from the nozzle surely, there is little space margin to arrange the nozzle close to the sprocket. There are great restrictions on the design, and it is difficult to reliably lubricate the target location when separated from the sprocket. Also, it is conceivable to dispose the nozzle inside the chain winding below the sprocket, and to spray and supply the sprocket from below, but in such a configuration, it is called the upper position of the raising case, The lubricating oil supply device is required to have a pump pressure that can secure a sufficient spray pressure even at a relatively high position, which leads to another problem that the cost of the entire lubrication device is increased. An object of the present invention is to provide a lubricating device that can prevent a lubricating oil supply from being hindered by straw or soil in a raising case and that can easily perform maintenance and inspection while avoiding an increase in cost. On the point.

[0004]

The present invention is characterized in that an elevating chain wound around an upper sprocket and a lower roller is provided in an elevating case in an inclined position, and lubricating means for supplying lubricating oil to the elevating chain. In the apparatus for raising a stem and stem for harvesting and harvesting provided with a spout, in order to form the lubricating means, a naturally falling oil guide is attached to a cover detachably provided on an upward surface of the raising case, and a receptacle at an upper end side of the oil guide. Is disposed below the refueling nozzle, and the drip port on the lower end side is provided to face the upward portion of the upper sprocket.

[0005]

[Function] That is, lubricating oil from the oil supply nozzle is supplied to the upper end side receiving port of the oil guide, and the lubricating oil that has naturally flowed down the oil guide is supplied from the lower end side of the oil guide to the upper sprocket in an upward direction. With this configuration, the lubricating means can be raised and arranged in the upper part of the case so that the supply of the lubricating oil is not obstructed by the straw or the soil which has entered the raised case. This prevents clogging with straw or soil. Moreover, since the oil guide is attached to the cover which is detachably provided on the upward surface of the raising case, the nozzle is guided by the oil guide while arranging the nozzle in a space with a sufficient space away from the upper sprocket. It is supplied to the upper surface of the upper sprocket, and can be surely guided to the meshing position between the target sprocket and the chain. In addition, since the nozzle can be installed sufficiently far from the upper sprocket, if you remove the oil guide,
A sufficiently large space for maintenance and inspection can be formed between the nozzle and the upper sprocket, and maintenance and inspection of the lubrication means such as inspection and cleaning of the oil guide can be easily performed by removing the cover.

[0006]

[Effects of the Invention] As a result, the supply of lubricating oil to the chain is not hindered by the straw or soil contained in the raising case, so that maintenance and inspection are easy and costs increase such as increasing the lubrication pump pressure. Thus, it was possible to provide a lubricating oil supply structure and a lubricating structure of a stem and stem raising device for cutting and harvesting which is more excellent in maintenance and inspection properties.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS As shown in FIG. 1, a mowing unit 2 is connected to a traveling vehicle body equipped with a crawler type traveling device 1 by a hydraulic cylinder 3 swinging around a support shaft 4 so as to be able to move up and down freely. A raising device having a raising case 5 with an upwardly inclined posture, a cutting blade 6, and a transport device 8 for feeding the cut grain culm to a threshing unit 7.
Threshing device 7 for threshing while providing the culm from the reaping unit 2 with a feed chain 9 to convey the culm.
Is mounted on the traveling vehicle body to form a self-removing combine. As shown in FIGS. 2 and 3, an elevating chain 12 wound around an upper sprocket 10 and a lower roller 11 to be driven is elevated and provided in a case 5, and an elevating elevating claw 13 is elevated at a predetermined interval. Attached to the chain 12 and raised, with the rotation of the chain 12, raised by the action of the lower roller 11 and the rising guide rail 14, the raised claw 13 is raised and raised in the working area and raised from the case 5; The raising claws 13 are configured to lie down and raise to retreat into the case 5. A cover 15 for inspection and maintenance inside the case is detachably attached to the upward surface of the raising case 5, and a pair of upper and lower pins 16 provided on the cover 15 is provided.
The raising case 5 has a support shaft 17
The cover 15 is raised and fixed to the case 5 by engaging the stopper 19 provided so as to be freely rotatable around and rotated and urged in the engagement direction by the torsion spring 18. It is composed. In order to form the lubricating means for supplying the lubricating oil for the raising chain 12 to the upper sprocket 10, a naturally flowing oil guide 20 having a tubular shape or a gutter shape is detachably attached to the cover 15, and an upper end side of the oil guide 20 is provided. Socket 20a
Is arranged below an oil supply nozzle 21 connected to a manually operated or electric pump (not shown), so that lubricating oil is supplied dropwise from the oil supply nozzle 21 to the receiving port 20a. Of the upper sprocket 1
0, the lubricating oil naturally flowing down the oil guide 20 is supplied dropwise from the drip port 20b to the upward portion of the upper sprocket 10.
The lubricating oil supply is favorably supplied to the chain 12 without causing the supply of the lubricating oil to be hindered by the straw or the soil that has entered therein, and without the receiving port 20a and the dropping port 20b of the oil guide 20 being clogged with the straw or the soil. Thus, maintenance and inspection of the lubrication means such as inspection and cleaning of the oil guide 20 can be easily performed by removing the cover 15.
