Description

[Detailed explanation of the idea] The present invention relates to a lubricating device for a reaping and tying machine, etc.

Conventionally, for example, lubricating the required lubricating points of a reaping and tying machine has been done manually using an oil pitcher, or an automatic lubricating device has been installed to eliminate the disadvantages of this, such as forgetting to lubricate some parts and the complexity. However, the operating section of conventional automatic lubrication devices is located in the machine's operating section, and this is not the case with walk-behind working machines, such as reaping and tying machines, where the operating section is located at the rear of the machine. The problem was that it was not possible to visually check the lubrication status of each lubrication point during lubrication, leading to excessive lubrication or lack of lubrication being overlooked.

In view of the above problems, the present invention improves the reliability of lubrication and enables appropriate lubrication.The present invention is designed to improve the reliability of lubrication and to perform appropriate lubrication.The oil feed pump is placed at the appropriate location in the pretreatment section to supply lubrication to the points in the pretreatment section that require lubrication. The operating part of the operating mechanism for starting and stopping the oil feed pump is separated from the operating part of the machine, and the operator can visually check the points requiring lubrication while operating it. The present invention provides a lubricating device for a reaping and tying machine, etc., which is disposed at a relatively low position on one side of a pre-processing section so as to be able to do the same.

The present invention will be explained below based on the embodiments shown in the figures.

Referring to FIGS. 1 and 2, running wheels 1 are mounted on the machine body, and a pre-processing section consisting of a reaping device 2, a culm lifting device 3, a lateral conveyance device 4, a binding device 5, etc. is attached to the front of the machine body. A reaping latch 7 for activating and deactivating each device 2, 3, 4.5 at the front of the machine, a running latch for running and stopping the machine, etc. are arranged at the rear of the machine. A reaping and tying machine 9 is provided with a driving section 8, and a reaping and tying machine 9 is configured such that an operator holds the culm at the rear of the machine and cuts and ties the husks while driving the machine.

The lifting device 3 includes a lifting chain 712 that is wound around a pair of sprockets 10 and 11 and has a plurality of tines protruding from it.
are provided in a pair on the left and right so that the rotating action direction is rearward and upward, and by driving the sprocket 11, the raising check 712 is rotated to raise the fallen shell culm to a substantially upright position. It is structured as follows.

In this embodiment, the portion of the culm lifting device 3 that requires lubrication, that is, the area around the lower sprocket 10, is transparent so that it can be easily recognized.

The reaping device 12 consists of a fixed receiving blade 13 provided along the width direction of the machine body, and a sliding cutting blade 14 placed on the upper surface of the fixed receiving blade 13 so as to be slidable in the width direction of the machine body. A cutting blade drive consisting of a swinging arm 16 engaged with a locking pin 15 protruding from an appropriate part of the sliding cutting blade 14, and a swinging shaft 17 fixed to swing the swinging arm 16. By the mechanism,
The sliding cutting blade 14 can slide left and right.

The structure is such that the culm can be harvested by harvesting.

The lateral conveying device 4 carries a conveying ceno 18 having a plurality of protruding conveying protrusions whose conveying surface is above the sliding cutting blade 14 and substantially along the longitudinal direction of the cutting blade 14, and the conveying direction is toward the binding device 5. It is wound around the driving sprocket 19 and the driven sprocket 20 so that the driving sprocket 1
The conveying cheno 18 is rotated by the rotational drive of 9, and the cut husk culm is conveyed toward the binding device 5.

To explain the power transmission mechanism for operating each of the operating parts, referring to FIG. The shaft is fixed so that it can rotate freely, and the transmission case 2
The tip of a power take-off shaft 24 connected to the engine 23 is inserted into the engine 23, and the power take-off shaft 24 and drive are connected to each other via bevel gears 25 and 26 externally fitted and keyed to the shafts 22 and 24, respectively. The lower end of the drive shaft is connected to the lower surface of the transmission case 21 to pivotally support the swing shaft 17, the shaft 19a of the drive sprocket 19, and the operating shafts of the binding device 15. It extends into the binding case 27 and transmits power from the drive shaft 22 to each shaft 17, 19a via a gear mechanism (not shown) inside the binding case 27.

Further, power is also transmitted to the culm lifting device 3 from an appropriate sprocket 19 or 20 of the lateral conveyance device 4 via an appropriate chain transmission mechanism.

Next, the oil filling device 30 will be explained.

An oil feed pump 29 (for example, a known small gear pump) is provided, which is located directly above the drive shaft 22 and is operatively connected to the drive shaft 22 via a pump clutch 28 of the operating mechanism, which is the main point of the present invention. The suction port of the oil feed pump 29 is communicated with an oil tank disposed at an appropriate location on the aircraft through an oil pipe 31, and the discharge port 32 is connected to a distributor 3 with a check valve.
The distributor 33 is connected to the distributor 33 by an oil pipe 34, and the oil nozzles 35, 36, 37, and 38 at the tips of the distributor 33 are connected to the locations that require oiling (i.e., appropriate locations of the lifting chees 73 and 3, and the swinging of the reaping device 12). Oil pipes 39, 40, 41 located facing the shaft 11, the sliding surface of the cutting blade 14, the horizontal conveyance chino 18, etc.
, 42 are communicated with each other to form a lubricating device.

The pump clutch 28 of the operation mechanism is as shown in FIG.
A hollow support body 43 is interposed between the upper surface of the transmission case 21 and the lower surface of the oil pump 29 where the drive shaft 22 is located,
The pump rotation shaft 44 of the oil feed pump 29 extends into the hollow support 43 concentrically with the drive shaft 22, and its tip is formed into a spline portion 44a having an appropriate length, and a plurality of spline portions are formed on the circumferential surface of the lower end. A clutch body 45 having a locking protrusion 45a and a spline formed on the inner circumferential surface is attached to the pump rotation shaft 4.
4, and an engaging pin 46 is fitted to the spline portion 44a of No. 4 so as to be vertically slidable, and has a rotational circumference larger than the outer diameter of the drive shaft at the upper end of the drive shaft 22, and is capable of engaging with the protrusion 45a. It is configured to be inserted in a non-removable manner.

In other words, when the clutch body 45 is lowered and the locking protrusion 45a and the engagement pin 46 are engaged, power is transmitted from the drive shaft 22 to the pump rotating shaft 44, the oil feed pump 29 is operated, and the clutch body 45 is raised. The locking protrusion 45a and the locking pin 46
When the power is disengaged, the power is not transmitted to the pump rotating shaft 44 and the pump 29 stops operating.

Regarding the configuration in which the clutch body 45 of the pump clutch 28 is slid up and down, an engagement groove 45b of an appropriate depth is provided along the outer circumference of the clutch body 45, and an appropriate side wall portion of the hollow support body 4 is provided with an engagement groove 45b. The operating shaft 46 is supported through the shaft part'.
The operating shaft 46' is located at one end located within the hollow support 45 of the shaft 46'.
An eccentric operating pin is provided protruding from the operating shaft 46 so as to move up and down as the operating shaft 46 rotates, and the operating pin 47
is always locked in the engagement groove 45b, and an operating arm 48 is fixed to one end of the operating shaft 46' located outside the hollow support 43 so as to rotate integrally with the operating shaft 46'. The arm 48 is locked with a bolt a so that it does not come off outward, and a tension spring button is interposed between the operating arm 48 and the body 9 to keep the clutch body 45 and the engagement pin 46 in a disengaged state. The base end of the operating lever 51 is fixed to the distal end of the operating arm 48 so that the operating arm 48 is biased to a rotating position where the operating arm 48 is rotated in a direction opposite to the biasing direction. The buffer portion 51a is formed by spirally winding the middle portion of the operating lever 51, and the operator pulls the tip portion 51b (operating portion) of the operating portion until it reaches a position where each of the locations requiring lubrication can be visually recognized. 51b is extended, and the operating part 51b is supported slidably in the tensile direction by a lever support 52 fixed to the front surface of a vertical plate 54 located behind the lower conveyance plate 53 and in front of the wheel 1. .

That is, by pulling the operating portion 51b, the operating arm is rotated, the operating pin 47 is eccentrically moved downward, the pump clutch 28 is turned on, and the oil feed pump 29 is operated to lubricate each location that requires lubrication. When lubrication is completed, by releasing the hand from the operating portion 51b, the action of the tension spring 50 causes the operating arm 48 to return to the energized position, thereby stopping the lubrication.

In this embodiment, the operating section 51b is located at the end position on the cut side in the rear lower part of the pre-processing section 6, so that the operating section 51b is separated from the driving section 8 and can be operated while visually checking each lubricating point.
b, and in this case, it is far from the operating parts, so lubrication work must be done only when the aircraft is stopped. This not only improves the reliability of lubrication, but also improves the reliability of lubrication because the lubrication operation can be performed while checking the lubrication status of each lubrication point. By being located at the uncut side end, lubrication operations can be carried out during work in the field without being bothered by the erect culms and without getting close to dangerous parts of each operating part.

Note that the position of the operating part 51b may be any position as long as it is separated from the driving part 8 and each location requiring lubrication can be visually recognized.
Depending on the type of reaping and tying machine, the number of locations requiring lubrication, and the arrangement positions, it is not necessarily limited to the already cut side of the rear lower part of the pretreatment section 6.

As described above, the present invention provides an oil feed pump for lubricating the lubricating points of the pre-treatment part in the pre-treatment part, and drives the oil feed pump as appropriate by a drive mechanism, and performs operations for starting and stopping the oil feed pump. The lever support of the operating section of the mechanism is fixed to the front of the vertical plate located behind the lower conveyance plate and in front of the wheels, and the operating lever is placed at a relatively low position on one side of the preprocessing section. Therefore, the operating part of the operating mechanism for starting and stopping the oil feed pump is located far away from the operating part of the machine, so careless lubricating while the machine is running may cause waste to be applied to each operating part, such as straw waste. It is possible to prevent build-up, etc., and since the operating part is located in the pre-processing part, the operating lever extends directly from the oil feed pump provided in the pre-processing part, allowing easy and reliable operation. At the same time, when the pump is operated, the operator must operate the control lever in a crouched position from one side of the pretreatment section, which inevitably forces him to monitor the lubrication area, making the lubrication operation more reliable. There are effects that can be achieved.
