JPS5927294Y2 - Main clutch operation structure on the front handle - Google Patents

Description

[Detailed description of the invention] This invention relates to the structure of the main clutch operation structure that can be pressed on the front part of the power cultivator with an operating handle that can be attached and detached at will, and can be separated when packing, making it easier to pack. It is.

Generally, when using a tiller to perform various tasks such as raising tillage ridges, the front part of the tiller is placed so that the worker can easily see the work and to prevent damage to the finished ridges. Work may be performed by energizing the needle in position.

In this case, the main clutch lever that operates the tiller is located at the rear.
Due to the location of the 5th dollar, it has already been proposed to connect this with a connecting rod that can be operated from the front of the 5th dollar.

However, in the case of conventional connection using a single rod, it is necessary to adjust the length of the rod as the clutch disengagement position changes, and the front bundle must be removed and packaged at the product shipping stage. The presence of a rod with a fairly long side was an obstacle and caused inconvenience in packaging.

The present invention allows the rod to be divided into several pieces in order to deal with this new problem.

Embodiments of this invention will be described below with reference to the drawings.

A normal rear part of the tiller main body 1... A front part where a front handle 3 is provided at the front position opposite to the handle 2... The handle 3 is connected to the left and right grip arm rods 4, 4' and a connection that connects these to each other. It consists of a rod 5, and a rod guide 6 is further formed on the connecting rod 5.

Front part: The base of the handle 30 is placed on the front part of the power tiller and is attached to the base I.
It is said that it can be inserted into and removed from the short tube 8 whose angle is adjustable, which is fixed to the short tube 8, and the adjustment bolt 9 is used to adjust the angle adjustment button of the short tube 8, adjust the position of the front part, the base of the handle 3, and fix it. It will be done.

In particular, during packaging and transportation, the front bundle can be removed from the short tube and stored and packed in any space within the aircraft in a compact state.

A linking rod 11 for linking with a main clutch handle 10 buttoned on the rear handle 2 is passed through the front guide 6 of the folded front handle 3, and its tip is curved.

As an example of dividing the linking rod 11 and adjusting its length, the linking rod 11 is cut to an appropriate length, and a button is attached to the end of the linking rod 11.
+B 12 is inserted slightly and integrated by welding or the like.

On the other hand, one end of the other split linking rod 11 is inserted into the opposite end of the sleeve 12, and a threaded hole is formed in the radial direction at an appropriate location in the sleeve. It is fastened so that it can resist tensile force.

By providing appropriate combinations of these, the linked rod 1
1 is divided into predetermined lengths 1, and is assembled into a single connecting rod 11. The length is also the stop bolt 1 of the sleeve 12.
The insertion length to the 3rd side can be adjusted.

It is.

Next, this idea involves attaching the connecting rod 11 to the front section of the steering wheel 3, and attaching the connecting rod 11 to the rear section, the main clutch installed on the steering wheel 2.
The attachment to the handle 10 has also been devised.

In other words, for the front bundle 3 side, the connecting rod 5 is the arm rod 4.
.

A vinyl hose 15, for example, is covered from the point where the connecting rod 11 passes through the rod guide 6 to the bent portion on the end side.

With this configuration, the linking rod 11 is
This makes it possible to absorb the noise generated when the rod comes into contact with the connecting rod 5, rod guide 6, etc.

Furthermore, it can also be expected to have the effect of preventing damage to the parts and enhancing the feel of the grip.

On the other hand, when facing the rear side of the steering wheel 2, an arch-shaped main clutch steering wheel 10 is rotatably constructed across the left and right control rods 16, 16 by a support shaft 17 or the like.

Thus, the attachment body 18 of the link rod 11 is fixed at a proper location at the top of the main clutch bundle 10.

The mounting body 18 is rotatably connected via an end member 19 of the linking rod 11 with a pin 20 or the like.

The attachment body 18 is composed of a flat plate body 18a, a half-shaped grip body 18b connected to the flat plate body 18a, and two tongue-like bodies 18c connected to the flat plate body 18a. ...Insert the top of the handle 10 and tighten with the screw 21 and nut 22 that pass through the tongue 18°.

In this case, if a buffer body 23 such as a rubber pipe or a vinyl pipe is interposed between the two, the main clutch bundle 10 can be firmly fixed to the main clutch bundle 10, and vibrations can be absorbed without shifting from side to side.

Furthermore, this acts as if it were a packing material, allowing the member to be attached without damaging it.

As described above, the linking rod 11 is used to connect the front part to the handle 3 and the rear part to the
・Since the operating tools installed in Handle 2 are connected and can be separated, there is no possibility that the connecting rod may protrude from the packaging during packaging, resulting in separate packaging or larger packaging. It is something that will be resolved.
