Description

[Detailed Description of the Invention] The present invention relates to an oil supply device for a reaper, which is provided with a nozzle having a first discharge port that spouts lubricating oil in the longitudinal direction above the horizontally suspended clipper-type cutting blade. .

Conventionally, in this type of device, the lubricating oil was ejected only in the longitudinal direction of the clipper-type cutting blade, so there was a problem that the lubricating oil tended to be insufficient near the nozzle.

In view of the above points, it is an object of the present invention to make it possible to uniformly and sufficiently lubricate the clipper type cutting blade over its entire length in the longitudinal direction by simple structural improvement.

Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

A pair of left and right lifting devices 1 that pull up two rows of planted culms in the field, a clipper type reaping device 2 that reaps the raised culms, and a guide cover 3 to guide the cut culms along one side of the machine. A stock head locking and conveying device 4 and a tip locking and conveying device 5 transport the culms to the binding space S on the other side, and a binding device 6 that binds a predetermined amount of culms collected in the binding space S and releases them to the outside of the mechanism. , a binder as an example of a reaper, which is connected to a traveling body which is equipped with an engine 7 and has a control handle 8 extended to the rear, and which is used to continuously bind planted culms in a field while traveling with the body. It consists of:

The aircraft body is equipped with a tank 9 for storing lubricating oil, and a manual lubricating oil suction pump 10 is attached to the control handle 8, and the operation of the pump 10 draws lubricating oil from the tank 9 to the various types. Large diameter main pipe 1 to drive unit
It is configured to be pumped through 1.

As shown in FIG. 2, the main pipe 11 includes:
Three small-diameter, flexible branch pipes 13 a , 13 b , and 13 C are connected via the joint 12 , and the two branch pipes 13 a and 13 C are joined in the middle, respectively) 14.14. Further branch pipe 15a via
, 15b are connected, and the pipes 13a, 13b, 13C,
15a.

15b, respectively, using the left and right lifting devices 1, 1. Chains 16 and 17 for driving the reaping device 2, the stock locking and conveying device 4, the binding device 6, and the joint portion 18 consisting of the bill, holder, etc. of the binding device 6 are located close to or connected to each other, and lubricating oil is applied to each. The oil supply device is configured to supply the following.

19 in the figure indicates branch pipes 13a, 13b,
13C.

Check valves 15a and 15b are installed to prevent natural outflow.

A branch pipe 13b extends from an upper side of the clipper-type cutting blade 2a of the reaping device 2 on the side opposite to the binding device 6, and a nozzle 20 is connected to the tip of the branch pipe 13b.

A first discharge port 21 is provided at the tip of the nozzle 20 for spouting lubricating oil in the longitudinal direction of the cutting blade 2a, and
At the proximal end side of the connection with the pipe 13b, a cylindrical portion 22 is provided below.
A second discharge port 23 for spouting lubricating oil is bored there near the nozzle 20 of the cutting blade 2a.

The second discharge port 23 has the same diameter as the first discharge port 21, but the cylindrical portion 22 is made relatively long so that the flow resistance caused by the lubricant jetting is greater than that of the first discharge port 21. Therefore, a large amount of lubricating oil is spouted from the first discharge port 21, and the entire longitudinal direction of the cutting blade 2a is lubricated, and a small amount of lubricating oil is spouted from the second discharge port 23. The structure is such that a small area near the nozzle 20 of the cutting blade 2a that is not oiled is supplied with oil from the first discharge port 21, and the entire length of the cutting blade 2a in the longitudinal direction can be oiled.

In the figure, A and B are the first discharge port 21 and the second discharge port 23, respectively.
This figure schematically shows the range of lubricant oil ejected from the pipe.

FIG. 4 shows another embodiment in which a check valve 24 is provided inside the nozzle 20.

That is, a valve body 27 is provided at a communication port 25 between the pipe 15b and the nozzle 20 via a biasing tool 26, and the communication port 25 is normally closed by the biasing force of the biasing tool 26, and when refueling, the pump 10 is used to close the communication port 25. It is configured to open the communication port 25 against the urging force.

Therefore, not only can the check valve 19 be made unnecessary, but it can also be provided near the discharge ports 21 and 23, so that the amount of lubricating oil flowing out due to machine body vibration when refueling is stopped can be minimized.

FIG. 5 shows another embodiment in which the nozzle 20 is made of a steel pipe, in which the first discharge port 21 can be easily formed by press working, and the connection point with the pipe 13b can be easily formed by press working. It can be expanded and is advantageous in terms of manufacturing.

In the figure, reference numeral 28 denotes a mounting plate for mounting the nozzle 20 to the aircraft body, which has a curved edge and is integrally welded to the nozzle 20 by brazing with the nozzle 20 fitted onto the outside.

Note that the present invention can be applied to various types of reaping machines such as combines.

In summary, the present invention provides the above-mentioned reaping machine oil supply device, in which the nozzle is arranged at one end of the reaping device, and lubricating oil is supplied downward toward the cutting blade portion located near the nozzle. A second ejection port is formed in the nozzle, and the second ejection port has a higher flow resistance than the first ejection port.

In other words, although it is a simple structural improvement of just providing the second discharge port 23 in the nozzle 20, the flow resistance is made larger than that of the first discharge port 21, so that the first discharge port 21 has less influence on the lubricant jetting, and By spouting lubricating oil from the second discharge port 23 to supply lubricating oil to the mower blade portion near the nozzle 20 that is not supplied with lubricant by the first discharge port 21, the mower blade 2
a Lubricating oil can now be applied evenly over the entire length in the longitudinal direction.
