Description

[Detailed Description of the Invention] [Industrial Field of Application] The present invention relates to a device for adjusting the vertical movement of a wheel in a binder, which allows the vertical movement of the wheel to be adjusted by stepping on it.

[Conventional technology]

Conventionally, a binder is constructed by mounting a wheel mounted on the tip of a swing-type axle case so that the vertical movement can be adjusted freely relative to the aircraft body, and the structure is such that the vertical movement of the wheel can be adjusted using several levels of stoppers and ratchets. Therefore, when adjusting the vertical movement of the wheel, the operator had to go to the side of the wheel and operate the ratchet, which resulted in poor footing when the field turned into a wet field. The operation was particularly difficult when the cutting was on the uncut side.

[Problem that the invention attempts to solve]

The present invention solves such problems and has a simple structure that allows the operator at the rear to quickly and easily operate the wheels by simply stepping on the pedal with his or her foot when lowering the wheels when entering a wet field. The purpose of this document is to provide the following information so that it can be carried out suitably.

[Means for solving problems]

Therefore, in the present invention, a telescopic hydraulic jack is interposed between the tip side of the axle case and the machine frame, and a plunger pump for the jack is installed below the jack near the tip side of the axle case. It is constructed by providing a pedal for operating the.

[Effect]

Therefore, when an operator operating the vehicle in a wet field or the like depresses the pedal, the hydraulic jack is activated to lower the wheels.

〔Example〕

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

Fig. 2 shows a side view of the binder, in which a transmission case 6 is connected to the lower side of the engine E at the rear of the fuselage, an operating lever 7 is protruded above the transmission case 6, and a weed divider plate is installed. 8. The rear part of the reaping and tying device B, which is equipped with a pulling case 9, a cutting blade 10, a tying machine, etc., is connected to the engine E and the front part of the transmission case 6, and the rear part 3a is connected to the side of the transmission case 6. The machine frame 3 is fixed to the section and extends forward.
The front part of the transmission case 6 is connected to the reaping and tying device B, and a handle rod 11 is extended from the top of the front part of the machine frame 3 toward the rear of the machine body. Rear part 1 of tilting swing type axle case 1
A is rotatably connected for transmission, and one wheel 2 is mounted on an axis inside the front end of the axle case 1, and the wheel 2 is installed so that it can be moved up and down by the swing of the axle case 1. The structure is the same as the conventional structure.

A hydraulic jack A similar to the conventional type is interposed between the tip side of the axle case 1 and the machine frame 3 above it, and the lower part of the jack A is connected to the axle case 1.
The upper end holder 14 of the ram 13 extending vertically is connected to the support 15 of the machine frame 3 via the connecting shaft 16, and the rear part of the jack A vertically movable operating rod 17 that operates the plunger pump 4 extends upward, and the front swinging support rod 18 and the upper part of the operating rod 17 are connected to the lower front and back of the pedal 5 so as to be freely rotatable. The pedal 5, which extends rearward from the outside of the axle case 1, is connected to the boot 1 of the operator's foot.
9 so that it can be stepped into.

Therefore, in dry fields, harvesting and tying work must be carried out with the wheels 2 raised relative to the machine body, as shown in FIG.

In addition, in cases where the reaping binding device B is raised due to falling into mud in a field, or when operating in a wet field, the operator operating at the rear of the machine may stretch out his/her legs, place the boots 19 on the pedals 5, and then press the arrow button. When you press pedal 5 as shown in
The hydraulic jack A operates, and as the ram 13 rises, the axle case 1 swings and the wheels 2 descend, lowering the wheels 2 relative to the aircraft as shown in Figure 3. As a result, although the wheels 2 are lowered, the reaping and tying device B can maintain its normal reaping posture and perform work.

When lowering the wheel 2 in this way, the degree to which the wheel 2 is lowered can be adjusted by the number of times the pedal 5 is depressed.

In order to lower the machine (raise the wheels) and return it to the state shown in FIG. 2, the oil in the cylinder of the hydraulic jack A is drained by opening the relief valve using another operating tool (not shown).

[Effect of idea]

In this way, the present invention enables the hydraulic jack A to be activated by simply stepping on the pedal 5 when the operator falls into the mud in the field or when working in wet fields.
This means that the wheel 2 can be lowered quickly and easily by activating the wheel 2, and by raising and lowering the wheel 2, it is possible to escape from mud or work in wet fields, and it can be carried out suitably with a simple structure. It has characteristics.
