Description

[Detailed Description of the Invention] The present invention relates to a device for adjusting the vertical position of a wheel in an agricultural working machine.

That is, the vertical position of the wheels installed on the sides of the transmission case can be adjusted reliably and easily, and the wheels can be well supported without the axle portion overhanging the transmission case too much.

The present invention is provided so that the wheel can be protected by a case that directly supports the wheel, so that it can be immediately and suitably applied to, for example, a one-wheeled agricultural working machine.

Next, the embodiment shown in the drawings will be described.

Figure 1 shows a side view of a binder, which is an agricultural working machine.
An input shaft 2 with an input pulley 1 extends outward from the upper part of a transmission case A located on one side of the aircraft, and an engine E is mounted on a frame 3 supported at the rear of the transmission case A. The power is transmitted to the input pulley 1 via the belt 4, and a handle 5 is extended from the upper part of the frame 3 toward the rear of the machine, and a transmission case A is provided.
The reaping and binding device B is installed on the reaping frame 1 that extends forward and supports the transmission case A, and the reaping and binding device B has the same structure as the conventional structure. Grass dividing board 8, raising body 9, sled body 10, cutting blade 11. conveyance plate 12,
A belt 16 is wound around the input pulley 14 of the device B and the side pulley 15 of the input pulley 1.

Inside the transmission case A, the small gear 17 of the input shaft 2 and the large gear 19 on the lower transmission shaft 18 are engaged, and the clutch gear 20 on the transmission shaft 18 can be operated by the lever 21 of the handle 5. In this way, the clutch gear 26
is attached to and detached from the large gear 19, and a support cylinder portion 22 is provided to protrude from the lower inside of the transmission case A toward the center of the fuselage.
A drive shaft 24 is mounted on the support tube 22 via a bush 23, and a large gear 25 fixed to the inner end of the drive shaft 24 in the transmission case A is always engaged with the clutch gear 20.

A is a small case, and a cylindrical portion 26 formed at one end side of the case a is rotatably fitted into the support cylindrical portion 22, the drive shaft 24 is inserted into the case a, and the bearing 30 is inserted into the case a. A drive shaft 24 is provided protruding from the side of the case a, which is the opposite side to the cylindrical part 26, and an axle part 24' is formed at the tip of the drive shaft 24. A suitable transmission mechanism 29.28 housed in the case a connects the supported shaft 27' in conjunction with the shaft 27', and the axle portion 2γ at the end of the shaft 27' is connected to the case a in the same manner as the axle portion 24' of the drive shaft. It is constructed by protruding outward.

A thick wall portion 31 is formed on the side surface of the transmission case A above the twisted support cylinder portion 22, and a large number of screw holes 32 are formed in the thick wall portion 31 on a concentric circle around the drive shaft 24.
are formed at intervals, a support part 33 integrally extends above the cylindrical part 26 side, and a bolt 34 passing through the distal end side of the support part 33 can be screwed into each screw hole 32. .

CI/'i is a wide wheel, and the rim part 36 extends outward from the outer periphery of the disc part 35 at the center in the width direction.
．． However, since the wheel C is wide, deep recesses 37 and 37' are formed on both sides.

In the housing, 38 is a flange boss, which is attached to both axle portions 27 and 24.
The flange 38 is provided so that it can be fitted into the boss, and is integral with the boss.
' and the disc part 35 of the wheel C can be fixed with bolts 39, and a hole 40 is formed in the disc part 35.

Therefore, when the flange boss 38 is attached to either the axle part 24' or 27, the wide wheel C is located at the center of the width of the aircraft body, forming a single-wheel binder, and the case a on the side of the transmission case A is It has a structure in which it extends into one recess 37 of the wheel C and is protected by the wheel C.

As shown in Figures 2 and 3, case a is attached to bolt 3.
4, fit the flange boss 38 to the axle 24', and tighten the bolt 39 by inserting an L box spanner from the hole 40 or by inserting a spanner from the outside of the recess 31.
The entire fuselage can be supported from the transmission case A as the wheels C in a normal state.

Then, remove the flange boss 38 from the axle part 24', rotate the case a around the drive shaft 24 by fitting and rotating the support cylinder part 22 and the cylinder part 26, and move it as shown by the solid line or imaginary line in FIG. When the flange boss 38 is added to the axle portion 21 as shown in FIG. 5 while the bolt 34 is screwed into the corresponding screw hole 32 and fixed as shown, the wheel C is ie, the transmission case A to the fuselage section is lifted to a raised position.

Similarly, by rotating the case a, the vertical position of the wheels C can be adjusted, and the center of gravity of the machine can be moved up and down, and the machine can be adapted to work in wet fields, or to adjust the machine body.

In this state, the case a is still in the recess 37 of the wheel C.
You can enter a protected state by looking inside.

In addition, in the above-mentioned embodiment, the wheel C can be moved in the front-rear direction to accommodate the adjustment of the vertical position of the wheel C.

In this way, the present invention uses the wheel drive shaft 24 protruding from the transmission case A as an input shaft, and the other output shaft 21' interlocked with this shaft.
A small case A, which is provided at an eccentric position, is attached to the support cylinder part 22 of the transmission case A so as to be freely fixed in a plurality of rotational positions around the wheel drive shaft 24, and the small case A is provided with the wheel drive shaft 24 and the other output shaft 27'. Both the shaft ends of the small case A are formed into an axle part by protruding outward, and the wheels C can be attached to these axle parts as an alternative, so the case on the side of the transmission case is By rotating, the vertical position of the wheel fixed to the axle can be reliably and easily adjusted, and the case can be housed in the side recess of the wheel to protect it. Such an attachment allows for a good configuration in which the axle does not overhang the transmission case, and is particularly suitable for single-wheel binders.
