Description

[Detailed Description of the Invention] The present invention relates to a cutting blade lubricating device for lubricating a cutting blade device in a grain culm reaping machine such as a combine harvester or a binder.

Generally, the cutting blade device installed in this type of grain culm reaper is lubricated to reduce wear between the cutting blade and receiving blade, and to reduce the cutting resistance of the grain culm and perform smooth grain culm reaping work. It is essential to lubricate the cutting blade evenly with oil. By the way, in order to lubricate the cutting blade device with lubricating oil, a lubrication nozzle must be installed near the top of the cutting blade device, and for this reason, the grain culm comes into contact with the lubrication nozzle during reaping work, preventing the transportation of the husk. There was a drawback that the oil filling nozzle could become turbulent or clogged with mud and clog the nozzle opening, making it impossible to carry out smooth oil filling work unless the clogged oil filling nozzle was replaced.

The present invention was devised in order to eliminate these drawbacks in view of the above-mentioned actual situation, and its purpose is to provide a mounting frame for attaching and fixing the lower part of the grain culm combing body or the grass cutting body. , we focused on the fact that there was a support that supported the oil nozzle, extending perpendicularly to the cutting blade device along the width of the machine, and extending above and in front of it. The mower is fixed from above to the weeding frame of the intermediate weeding body extending upwardly and forwardly, the base end is fixed to the body side behind the cutting blade device, and the mower is arranged in the front-rear direction along the upper surface of the weeding frame. At the same time, the oiling nozzle is configured to direct the oiling from above the cutting blade to the left and right sides of the cutting blade, so that the grain culm comes into contact with the oiling nozzle during reaping work, which may disrupt the conveyance of the grain culm or prevent the oiling nozzle from reaching the oiling nozzle. A grain culm reaper that prevents mud from becoming clogged and obstructed, allows the cutting blades to be lubricated evenly at all times, and in which the support for the lubricating nozzle serves as a reinforcing frame for the middle grass. The present invention aims to provide a cutting blade lubrication device for use in the industry.

The structure of the present invention will be described with reference to an embodiment shown in the drawings. Reference numeral 1 denotes a pre-processing section of a combine harvester, which is an example of a grain culm reaper, and an upper part of a rear frame 1a of the pre-processing section 1. An oil tank 2 is attached to the. A hydraulic pump 3 is provided below the oil tank 2, and pumps the lubricating oil in the oil tank 2 to an oil feed pipe 4 formed of a flexible pipe. The oil pipe 4 is branched via a T-shaped pipe 4a, and one branch pipe 5 is piped into a combing case 6 installed obliquely at the front of the pretreatment section 1 with a lower front and a higher rear. Alternatively, lubricating oil is applied to the grain culm conveyance chain.
The other branch pipe 5a is made of a steel pipe that extends downward along the rear frame 1a and is fixed as a pipe along the lower frame 1b disposed in the machine width direction at the bottom of the pretreatment section 1. It is communicatively connected to the oil feed pipe 7.

Reference numeral 8 denotes a reaping frame extending forward from both ends of the lower frame 1b, and between the intermediate portions of the reaping frame 8, a cutting blade device 9 composed of a cutting blade 9a and a receiving blade 9b is connected to the lower frame 1b. It is mounted horizontally below the front of the aircraft, parallel to the main body. Lower frame 1b
A weeding frame 11 with an intermediate weeding body 10 attached to its tip is protruded at an appropriate interval in the middle part of the grass cutting frame 11, which is perpendicular to the cutting blade device 9 from the lower frame 1b. It detours above it and extends forward. The grain culm combing case 6 includes a mounting bracket 12 projecting upward from a position in front of the mounting position of the cutting blade device 9 of the reaping frame 8, and a weeding frame 11 extending from approximately the center of the lower frame 1b.
Similarly, they are each fixed to a mounting bracket 13a provided at the tip of a mounting frame 13 for mounting the grain culm combing case 6, which extends around the upper part of the cutting blade device 9. Furthermore, a weeding body 10a is fixed to the tip of the reaping frame 8, located in front of the grain culm combing case 6.

Reference numeral 14 denotes a semi-cylindrical support with an open bottom, and a weeding frame 11 is provided at the base end of the support 14.
Joint 15 provided in oil feed pipe 7 corresponding to the position
The tip of the is included. On the other hand, a lubricating nozzle 16 is fixed to the tip of the support 14 with a nozzle opening 16a formed in the left-right direction. Further, a joint 1 is connected to the inner side of the intermediate portion of the support body 14 via communication tubes 17 and 17a made of flexible tubes.
5, and a check valve 18 which is separate from the oil filling nozzle 16 and is connected in communication with the oil filling nozzle 16. 18a is a check valve of the check valve 18, and 18b is a biasing device that biases the check valve 18a.When lubricating is stopped, the lubricating oil on the oil feeding pipe 7 side is closed by closing the oil feeding pipe 7 side and the oil filling nozzle 16. On the other hand, when the oil pressure from the oil supply pipe 7 reaches a certain value during lubricating, the check valve 18 opens and the lubricating oil from the oil supply pipe 7 is sent to the oil nozzle 16, and is injected from the nozzle port 16a. I'm starting to do that. 19 is a fixed bracket fixed to the base end of the support body 14, 19a is a fixed bracket fixed to the lubrication nozzle 16, and the base end side fixed bracket 19 is attached to the mounting bracket 15a on the body side protruding from the joint 15. It is fixed via a tightening bolt 20, and the fixing bracket 19a on the tip side is fixed from above to the mounting bracket 11a of the grass dividing frame 11 via a tightening bolt 20a.
are arranged along the upper surface of the grass dividing frame 11 in the front-rear direction. In this state, the oil nozzle 16
is located substantially above the cutting blade device 9, and the nozzle opening 16
The lubricating oil injected from a is oriented in the left-right direction so that it is evenly applied to the cutting blade 9a over a wide area.

Next, the operation of the present invention constructed as described above will be explained. To supply lubricating oil to the cutting blade device 9, the lubricating oil pump 3 is driven to pump the lubricating oil in the oil tank 2 to the oil pipe 4. Part of the lubricating oil forced into the oil pipe is sent to a branch pipe 5 on the side of the pumping case 6 through a T-shaped pipe 4a, and the rest is sent to a branch pipe 5a and then forced into a steel oil pipe 7. The oil is sent from the check valve 18 to the oil filling nozzle 16 via the joint 15, and is sprayed widely from the nozzle opening 16a in the left-right direction, thereby evenly filling the cutting blade device 9 along the width of the machine.

In this way, the cutting blade device 9 can be oiled from the oiling nozzle 16, but since the nozzle opening 16a is located almost directly above the cutting blade device 9, the oiling is accurate.
Furthermore, the oil nozzle 16 has a configuration in which it is shielded from the field in the left and right directions by the cutting blade device 9, and furthermore, the oil nozzle 16 is shielded in the front and rear directions by the grass cutting frame 11 located below. Therefore, the lubrication nozzle 16 can prevent mud from adhering to the nozzle opening 16a by using the cutting blade device 9 and the grass cutting frame 11 without providing any other shielding device, and the nozzle opening 16a is almost never clogged. Accurate lubrication work can be performed over a long period of time without any problems.

In addition, on the route leading to the cutting blade device 9 while the standing grain culm is being divided or combed, the grain culm is guided and guided by frames 8, 11, and 13 protruding forward from the lower frame 1b such as the weeding frame 11. At this time, the lubrication nozzle 16 is fixed in the front-rear direction along the upper surface of the weeding frame 11 by the support 14, so that the grain culms are transported only by the lubrication nozzle. It is not disturbed by 16. The distal end of the support body 14 is fixed to the weeding frame 11 of the intermediate weeding body 10, and the base end is fixed to the mounting bracket 15a on the machine body side behind the cutting blade device 9, so that the intermediate weeding body 10 is fixed to the weeding frame 11 of the intermediate weeding body 10. Even if it receives a large resistance force when entering the grain culm, the support 14
serves as a reinforcing frame for the intermediate grass division 10 and can be reliably reinforced.

In addition, if the nozzle port 16a is clogged, after removing the tightening bolts 20, 20a and removing the lubrication nozzle 16 together with the support 14, the communication pipe 17a connecting the check valve 18 and the lubrication nozzle 16 is removed.
By removing the lubrication nozzle 16, you can easily clean the oil nozzle 16.
Can be reused immediately. This eliminates the drawbacks of conventionally using a lubrication nozzle that was integrated with the check valve, which made it difficult to clean the path from the check valve to the nozzle opening, which meant that the lubrication nozzle had to be replaced with a new one. That means that. Furthermore, even if the check valve 18 is provided separately from the oil filling nozzle 16,
The check valve 18 and the communication pipes 17, 17a are
Since it is protected by the support body 14 and the weed cutting frame 11, it will not come off during the mowing operation.

In the above embodiment, the base end of the support body 14 is fixed to the joint 15 of the oil pipe 7, but the present invention is not limited to this, and the support body 14 may be directly attached and fixed to the lower frame 1b.

In summary, the present invention provides a grain culm reaper in which a cutting blade device is provided along the width of the machine below the front of the machine body, and the cutting blade device is oiled through an oiling nozzle communicating with an oil tank. The support for supporting the oil nozzle is fixed from above to the weeding frame of an intermediate weeding body extending from the machine body perpendicularly to the cutting blade device and above and in front of it, and the base end is fixed to the cutting frame of the cutting blade device. The lubrication nozzle is fixed to the rear body side and arranged in the front-rear direction along the top surface of the grass dividing frame, and the lubrication nozzle is configured to direct lubrication from above the cutting blade to the left and right sides of the cutting blade. is supported on the upper surface of the weeding frame by a support fixed along the upper surface of the weeding frame to which the intermediate weeding body is attached and fixed. Conveyance will not be disturbed due to contact with the oil nozzle or support. Moreover,
The lubrication nozzle is shielded from the field by the lower weeding frame, which prevents mud from adhering to the nozzle, allowing the lubrication nozzle to perform accurate lubrication work without clogging over a long period of time. I can do it. Since the lubrication from the lubrication nozzle is directed from above the cutting blade to its left and right, it is possible to lubricate the entire surface of the cutting blade evenly along the width of the machine. The cutting blade is fixed to the rear of the machine body, so even if the weeds are in the middle of the grass, which is subject to great resistance when entering the erect grain culm, it is reliably reinforced by the support and the grain culm reaping operation can be carried out smoothly. It is something that can be done.
