Description

[Detailed description of the invention] The present invention provides a combine harvester in which the pre-reaping processing section is configured to be able to swing up and down around a fulcrum provided below the stem culm receiving plate of the threshing device. The present invention relates to a lubricating oil supply device for a combine harvester in which a cotton threshing device is connected to a lubricating oil supplying device installed in the cotton to supply lubricating oil to various devices.

According to this type of lubricating oil supply device, it is possible to supply lubricating oil to various devices in the pre-harvesting processing section and the threshing device while also serving as a lubricating oil hydraulic feeding device (for example, a hydraulic pump) and a lubricating oil storage tank. This has the advantage that lubricating oil can be supplied in a form that can reduce the cost of the overall structure.

The present invention aims to supply lubricating oil in a form that takes advantage of the above-mentioned advantages while further reducing the cost of the structure and reducing the adhesion of straw debris. In the combine harvester structure, a branch joint connected to a lubricating oil tank is provided below the stem culm receiving plate and near the fulcrum, and the branch joint and the reaping pretreatment section are connected to each other. A feature of the present invention is that the thresher and the threshing device are connected in communication with a lubricating oil supply device installed in the cotton via a flexible oil pipe.

In other words, lubrication is provided between the reaping preprocessing section and the threshing device through a branching joint placed near the lifting fulcrum of the reaping preprocessing section and a flexible oil pipe extending from the branching joint. Since this is a device that connects the oil supply equipment, for example, a special connection structure may be used to allow the pre-harvest processing unit to move up and down, and the lubricating oil supply equipment between the pre-harvest processing unit and the threshing equipment may be connected. Compared to the conventional structure where the flexible oil pipe and the branch joint are placed near the fulcrum, the structure is simpler than the one that connects the reaping pre-processing section to the threshing device. The lubricating oil supply equipment can be connected in communication, and since the branch joint is placed near the swinging fulcrum of the pre-harvesting section, it is possible to connect the branching joint far from the swinging fulcrum. In comparison,
There is less elongation of the flexible oil pipe due to the swinging of the pre-harvesting section.
There is no need for the flexible oil pipe to be left slack in order to have a margin, and there is no chance of the slack part getting caught on other equipment and causing damage.

Furthermore, since the branch joint is disposed below the stem culm receiving plate of the threshing device, the branch joint and the flexible oil pipe can be covered with the existing stem culm receiving plate. This prevents straw debris from scattering and adhering to the flexible oil pipe.

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

The figure shows a combine harvester in which a pre-reaping treatment section is connected to the front part of the machine in which a threshing device 2 is mounted on a crawler traveling device 1. It is configured to cut and process planted stem culms.

That is, the tree is planted using a pair of left and right lifting devices which are provided with locking claws 3a, 4a, and so on at appropriate pitches on chains 3 and 4 that are driven to wind. The two stem culms are pulled up and the base end of the plant is harvested using the hair clipper-type reaping device 5, and the stem culm locking and conveying claws 6a..., 7a...
The reaped stem culms are conveyed together by a pair of left and right auxiliary conveyance chains 6, 7 and a pair of left and right belts with protrusions 8, 9, and the combined stem culms are conveyed by a locking conveyance claw 10a...・
. . . In cooperation with a stock head clamping and conveying device comprising a pinching rail 12 disposed opposite to a tip-locking conveyance chain 10 and a chain 11 with protrusions, the stock is conveyed toward the rear, and the conveyance end portion is The structure is such that the grain is transferred to the threshing device 2 after being changed to a sideways posture.

The threshing device 2 clamps and conveys the base of the stem culm between the feed chain 1j and the clamping frame 14 installed on the side, and also transfers the tip of the stem culm to the upper part of the culm receiver plate 15. While loading, it is configured to be inserted into a handling chamber equipped with a handling cylinder 16 for handling and threshing, and the treated waste straw is sent to the waste straw shredding device 18 by a waste straw chain 17. It is configured as follows.

Further, the reaping pre-treatment section is supported via a support frame 19 that is swung up and down about a fulcrum P provided below the stem culm receiving plate 15, and the support frame 19 is It is configured to be raised and lowered relative to the machine as the hydraulic cylinder 20 expands and contracts.

Further, this combine harvester is equipped with a lubricating oil supply device described below.

That is, a pump 23 for pumping lubricating oil in a tank 22 is installed near a control seat 21 installed at the front of the threshing device 2, and this pump 23 and a fulcrum P of the support frame 19 are connected to each other. A branch joint 24 disposed nearby is connected to the joint 24 via a large diameter first flexible oil pipe 25, and the joint 24 is connected to a large diameter second flexible oil pipe 25.
Third and fourth flexible oil pipes 26, 27, 28 are connected.

The second oil pipe 26 extends toward the threshing device,
At its extending end side, there is a lubricating nozzle 29a, which is a lubricating oil supply device, facing the starting end of the feed chain 13, a lubricating nozzle 29b facing the terminal end of the feed chain 13, and a lubricating nozzle 29b facing the waste straw chain 17. Nozzle 30
are connected via small-diameter flexible oil pipes and branch joints.

The third oil pipe 27 is extended to the side of the reaping pre-processing section, and its extended end side faces the oil nozzle 31a facing the ear locking conveyance chain 10 and the chain 11 with protrusions. The oil supply nozzle 31b is connected via a small diameter flexible oil feed pipe and a branch joint.

The fourth oil pipe 28 extends toward the reaping pre-processing section, and at its extending end there are oil nozzles 32a, 32b facing the left and right ends of the reaping device 5, and left and right pulling chains 3, Lubricating nozzle 33a facing 4.

33b, and oil supply nozzles 34a and 34b facing the left and right auxiliary conveyance chains 6.7 are connected via a small diameter flexible oil feed pipe and a branch joint.

Therefore, if the pump 23 is activated, the tank 2
The lubricating oil in 2 is branched and supplied to various devices all at once.
