TECHNICAL FIELD The present invention relates to an extension axle for a manager, and more particularly, to an improved extension axle that can be applied in wide-ranging work such as a vinyl coating machine to expand wheel lubrication.

Typically, the walk-type manager 30 has a frame 32 on which the engine 31 is mounted, as shown in FIG. 1, and the work mechanism driving shaft taken out from the engine 31 is mounted on the rear side. To drive the machine.

A handle 33 having a lever for manipulator operation is connected to the rear of the frame 32, and the output shaft of the engine 31 transmits power to the transmission 35 provided to protrude downward from the frame 32. To drive the wheels 37 mounted on the axle 36 to allow traveling.

The above managers usually do rotary work and tillage work, but also perform tasks such as vinyl exposure. In this case, the wheels of the manager are narrow and the wheels of the wheels are narrow. The coating work becomes impossible.

In particular, if you want to perform vinyl coating work, the wheels are located in the ridge between the molded toad and the toad to prevent the damage of the toad covered with vinyl. This is because it reaches 70-200 cm wider than the lubrication of the manager.

In order to solve this problem, an extension axle is connected and used as a means for widening lubrication. A representative example is described below with reference to FIG. 7.

A connection hole 3 is formed at the end of the axle 2 protruding from the lower side of the transmission 1 to the both sides of the manager, and the axle 2 has a considerable length so as to widen the lubrication while accommodating the axle 2. Connect the tubular type connecting shaft (4) with the intermittent pin (5).

The connecting shaft 4 is formed with a plurality of adjusting holes (7, 8) to adjust the width of the wheel (6) to fit, and to mount the wheel (6) on the outer end of the connecting shaft (4) The hub for 9 is configured to couple to the intermittent pin (10).

In the prior art as described above, the axle, the connecting shaft, and the hub are connected to the intermittent pins, so that the dimensions and the assembly tolerances are generated. Due to the tolerances, the transmission is in a descending form, and the wheels are in an ascending form.

In this case, the clutch is provided on the axle, which affects the clutch, so that the clutch does not operate smoothly when turning the clutch. Is high.

In addition, the transmission is sagging downwards, and the lower part of the transmission touches the torso, causing damage to the torso, and thus there are various problems such as the inability to perform smooth work.

Therefore, the present invention has been invented to solve the problems as described above to improve the extension axle used to widen the lubrication of the manager to prevent sag phenomena to prevent damaging the dam as well as to prevent the operation of the clutch. The purpose is to increase the efficiency of the work as well as to contribute to the improvement of the quality of the manager.

Hereinafter, with reference to the accompanying drawings will be described a preferred configuration and operation of the present invention for achieving the above object.

1 is a side configuration diagram of a manager shown to explain the present invention, FIG. 2 is a cross-sectional view showing a transmission of a manager to which an extension axle for a manager according to the present invention is applied, and FIG. 3 is a manager to which the technology of the present invention is applied. 4 is a cross-sectional view illustrating an extension of the manager for applying the technique of the present invention, Figure 5 is taken along the line A-A of the manager extension axle shown in FIG. 6 is a cross-sectional view showing another embodiment of the extension axle for the manager to which the technique of the present invention is applied.

The conventional walking type manager 30 includes a frame 32 on which an engine 31 is mounted, and a work implement drive shaft taken out from the engine 31 enables to drive various kinds of work tools mounted at the rear. .

A handle 33 having a lever for manipulator operation is connected to the rear of the frame 32, and the output shaft of the engine 31 transmits power to the transmission 35 provided to protrude downward from the frame 32. To drive the wheels 37 mounted on the axle 36 to allow traveling.

In the present invention is coupled to the axle (36) extends outwardly and provided with no tolerances so that the transmission (35) and the wheel (37) does not fall or rise, the axle (36) to maintain a straight state with the axle (36) 40).

The extended axle 40 welds the axle base 42 to the mission case 41 at the portion where the axle 36 protrudes, and fixes the axle base 42 to the axle base 42 with a bolt 43. ).

The inside of the main housing 44 has an axle hole 45 of the square shape to be coupled to the axle 36 to receive the rotational force of the axle 36 and the outer diameter bearing an extension shaft 46 consisting of a circular shape Keep at (47).

The extension shaft 46 is coupled to the hub 49 having the connecting plate 48 with the intermittent pin 50 to mount the wheel 37, the wheel to the extension shaft 46 and the hub 49 In order to work the lubrication of (37), it is formed by forming a plurality of lubrication adjusting holes (51, 52, 53) to be adjustable according to the conditions or the ridge.

Of the lubrication control holes (51, 52, 53) of the lubrication control holes (51, 52) formed on the extension shaft 46 is arranged in a wide interval to enable a wide adjustment, the lubrication control formed on the hub (49) The spacing of the balls 53 is arranged in a narrow configuration to enable a narrow adjustment.

Extension axle 40 of the present invention configured as described above,

An extension shaft 46 is held as a bearing 47 in the main housing 44 fixed to the axle base 42 welded to the mission case 41 of the manager 30 by a bolt 43 so that the transmission 35 Since the axle 36 taken out from the coupled state, the extension shaft 46 is rotated together with the axle 36.

As the extension shaft 46 rotates, the hub 49 coupled to the extension shaft 46 with the intermittent pins 50 rotates, and the wheels 37 mounted on the connecting plate 48 provided on the hub 49. ) Will be driven.

In the process of performing the necessary work by driving the wheel 37 as described above, if you want to change the width (yunjae) of the wheel 37, the hub after breaking off the intermittent pin 50 that is regulating the hub 49 After moving the 49 in the left and right directions of the extension shaft 46 to the required width, the intermittent pins 50 are provided in the lubrication adjusting holes 51, 52, 53 formed in the extension shaft 46 and the hub 49. To control the length.

In particular, the lubrication adjusting holes (51, 52) formed in the extension shaft 46 is used to adjust the overall lubrication because the spacing is wide, using a lubrication adjusting hole 53 formed at a narrow interval in the hub (49) To adjust the lubrication through a small adjustment.

Since the extended axle 40 to which the technique of the present invention is applied is not coupled to the axle 36 by a pin and is inserted into the axle 36, an assembly (coupling) error or play is formed at the connection portion with the axle 36. Since this does not occur, the transmission 35 and the wheel 37 are prevented from descending and rising.

In this way, the main housing 44 supports and absorbs a load generated by the wheels 37, the hub 49, and the extension shaft 46, or a slight error occurring in the hub 49, and thus, is transferred to the axle 36. It is to prevent the operation to improve the power transmission while not affecting the clutch operation.

In another embodiment of the present invention, when it is necessary to make the lubrication wider, the auxiliary extension shaft 55 is further coupled to the outside of the extension shaft 46 to enable length adjustment with respect to the extension shaft 46, and the auxiliary The hub 49 may be attached to the outer end of the extension shaft 55.

The present invention as described above improves the efficiency of the work by improving the extension axle used to widen the manager's lubrication to prevent sagging phenomenon and to prevent damage to the toad, as well as preventing the operation of the clutch, as well as the manager. The invention has a variety of effects, such as can contribute to the improvement of quality.
