Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a lubrication device for a combine, for example, which supplies lubricating oil to each drive part of a reaping device.

Conventionally, as shown in Japanese Utility Model Application Publication No. 52-17745, there has been a technique in which a reaping section is provided with an oil tank and a pump, and the pump is driven by the driving force of the reaping section.

However, in the prior art, the tank and pump are provided on a frame that supports the entire reaping section, and the pump is connected to the reaping input shaft, so the tank and pump are built into the lower part of the reaping section. Therefore, there were handling and functional problems, such as not being able to easily fill or stop the lubricating oil by manual operation, and also not being able to easily check the remaining amount of lubricating oil inside the tank.

However, the present invention is characterized in that a lubricating tank is installed on the upper surface of the lifting drive case to which the upper end of the lifting case is attached, and a lubricating pump is drivingly connected to the end of the horizontal lifting shaft near the driver's seat. That is.

Therefore, it is possible to centrally install the tank, pump, distribution nozzle, etc., and the installation position of the switching lever for supplying or stopping the supply of oil can be placed close to the driver's seat, making it easy to operate it manually. In addition to this, the tank can also be visually checked in front of the driver's seat to easily check the remaining amount of oil, making it easy to check the oil amount and lubricate under working conditions such as during driving operations. The present invention aims to provide a lubrication device for combine harvesters.

Hereinafter, one embodiment of the present invention will be described in detail based on the drawings.

On the other hand, 28 is a drive sprocket for the traveling crawler 2, and 29 is a plurality of track rollers that are brought into sliding contact with the lower inner surface of the traveling crawler 2. Idlers 30 support the ends of the traveling crawler 2 together with the sprocket 28.

In addition, 31 is an auxiliary raising case that is arranged at right angles on the outside of the left raising case 10 to raise the lodging grain culm, 32 is a weeding plate facing the lower end of the auxiliary raising case 31, and 33 is a weeding plate. The straw cutting device 16
This is a straw collection table that is connected to the rear of the straw collection table.

Next, the oil filling device according to the present invention will be explained with reference to FIGS. It consists of a distribution nozzle 36 for distributing the oil sent out by the pump 35 to each drive part, and the tank 3
4 to the right and attach and connect the upper end of the case 10 to the tank bracket 3 on the upper surface of the drive case 37.
Installed via 8.

In addition, the pump 35 is connected to the right side of the right lift drive case 37 via a pump clutch case 39.
As shown in detail in FIG. 5, the pump 35 is pulled up via a clutch 40 built into a clutch case 39 and is connectably connected to the right end of a horizontal shaft 41. The horizontal shaft 41 is a bevel gear 4
2 and 43 to a lifting drive shaft 44, and also to a lifting shaft 48 of a lifting drive sprocket 47 which is meshed and connected to a lifting chain 46 via bevel gears 42 and 45, The rotation of the drive shaft 44 causes the horizontal shaft 41 and the pulling shaft 48 to rotate, and the clutch 4
0 to drive the pump as appropriate.

The clutch 40 is connected and disconnected by means of a clutch lever 49, and the lever 49 is pulled up to the left and right to protrude above the right end of the front gate 50, which is suspended between the upper parts of the cases 10, 10.
9, the clutch 40 is brought into the engaged state and the pump 35 is driven.

On the other hand, a discharge nozzle 52 of the tank 34 is connected to an inlet nozzle 51 of the pump 35 via a piping pipe 53 as shown in FIG. It consists of

Further, the discharge side nozzle 54 of the pump 35 is connected to the supply side nozzle 55 of the distribution nozzle 36 through the pipe 5.
6, and is configured to forcibly feed the oil in the tank 34 to the distribution nozzle 36 by driving the pump 35.

The distribution nozzle 36 is attached and supported to the tank bracket 38 via bolts 57, and as shown in FIG. 8, the nozzle 36 has a number of discharge nozzles 58 for sending oil to each drive section of the reaping device.
...is established. These discharge nozzles 58... are formed to change the inner diameter dimension to change the amount of oil supplied to each drive part, and these nozzles 58...
A portion thereof is configured to be detachably attached to the main body 36a of the distribution nozzle 36. In other words, the 8th
In the figure, the two on the left side have a main body 36a with a medium inner diameter.
Fixed type discharge nozzles 58a, 58a are fixed to the central part, and two screw type discharge nozzles 58b, 58b with a small inner diameter are attached to the main body 36a via a threaded part.
Also, the second one from the right side is the main body 36a with a medium inner diameter.
A screw-type discharge nozzle 58c is attached to the screw-type discharge nozzle 58c, and a discharge nozzle 58d, which has a large inner diameter and is fixed to the main body 36a, is attached to the rightmost end. The nozzle is constructed so that the amount of oil supplied can be adjusted by appropriately replacing the nozzle with another nozzle having a different inner diameter.

Further, the oil distributed from the distribution nozzle 36 is pulled up by the lifting chain 46 in the case 10.
As shown in FIGS. 6 and 7, a lifting lubrication nozzle 59 that supplies oil through a pipe 59a is inserted between a pair of left and right tine guides 61, 61 that sandwich and guide the chain 46 and the base end portions of the tines 60. The nozzle 59 is mounted and supported inside the lifting case 10 via the nozzle mounting plate 62, and the oil is sprayed on the side of the chain 46. The tip of the nozzle 59 is made to face the side of the chain 46 between the minimum horizontal swing positions of the chain 46 due to being guided by the guides 61, 61,
The lubricating position with respect to the chain 46 is kept constant at all times, so that the chain 46 is constantly and reliably lubricated.

The present invention is constructed as described above, and when lubricating, the clutch lever 49 is pulled up to put the clutch 40 in the "on" state, and the horizontal shaft 40 is turned on.
By drivingly connecting the pump 35 to 1,
The oil in the tank 34 is forcibly fed to each drive section through the distribution nozzle 36, and the oil is then pumped to each drive section, e.g.
9 to disperse the oil.

As is clear from the above embodiments, the present invention has a lubricating tank 34 installed on the upper surface of the lifting drive case 37 to which the upper end of the lifting case 10 is attached, and the driver's seat 2.
