Description

[Detailed description of the invention] The present invention has a cylindrical body for attaching resistance rods, which is fixed to a pair of left and right plate-like bodies attached to the vehicle body, and has a vertical shaft-like portion that is detachably connected to the vehicle body. This invention relates to a walking mobile agricultural machine equipped with an attachment connection frame.

The above walk-behind mobile agricultural machine can be used to perform tillage work by attaching a resistance rod and a tilling rotor to the shaft of the vehicle body, or to perform plowing work by attaching various attachments such as a soil cultivator using an attachment connection frame. The present invention, in a walking-type mobile agricultural machine having such advantages, prevents rotation of the vertical shaft portion of the attachment connection frame by a simple structure that effectively utilizes existing members. The purpose is to allow them to be connected in the same state.

Embodiments of the present invention will be described in detail below based on the drawings.

As shown in FIGS. 1 to 3, there is a front engine 1, a traveling transmission case 2 to which the output from the front engine 1 is transmitted, wheels 3, wheels 4 to which a tilling rotor 3A can be replaced, and a traveling transmission. A round resistance rod 5 is removably inserted into the rear part of the vehicle body equipped with a control handle 13 etc. that is bolted to the back of the case 2, and is removably attached in a state where it can be fixed with a pressing bolt 6. A cylindrical body 7 for attaching a resistance rod is provided,
Furthermore, an attachment connection frame 8 is provided which is L-shaped in side view and has a square vertical shaft portion 8a that is detachably connected to the vehicle body. A walking type mobile agricultural machine is constructed which can carry out various works by using various attachments such as a soil cultivator 9 and the like.

To support the resistance rod mounting cylindrical body 7, a pair of left and right plate bodies 10, 10 are welded to the base end of the handle 13, and a cylindrical plate is attached to the rear end of both the plate bodies 10, 10. Body 7 is welded. Then, the vertical shaft portion 8a of the attachment connection frame 8 is removably engaged between the plate-like bodies 10, 10 at the front portion of the cylindrical body 7 with respect to the plate-like bodies 10, 10. Both plate-like bodies 1 are in a state in which the plate-like bodies 1 are inserted, and in a state in which they are in non-rotatable contact with the inner surfaces of both plate-like bodies 10, 10, respectively.
0, 10 and the vertical shaft portion 8a, and are connected using a bolt 11 that is inserted through the shaft portion 8a. Moreover, the cylindrical body 7
A plate body 12 welded to the front surface of the bolt and the upper part of the front side of both plate bodies 10, 10 is adapted to abut and restrict the vertical shaft-shaped portion 8a from swinging back and forth around the bolt axis.

Incidentally, in the above embodiment, both the plate-like bodies 10, 10
The inner surface and the outer surface of the resistance rod mounting cylindrical body 7 on the front side of the machine constitute an attachment mounting portion A that holds the vertical shaft portion 8a in a non-rotating state.
As shown in FIG. 4, both the plate-shaped bodies 10, 10 are made to protrude further away from the vehicle body than the cylindrical body 7, and the inner surfaces of the plate-shaped bodies 10, 10 and the resistance rod mounting cylindrical body 7 are connected to each other. The outer surface on the rear side of the body may constitute an attachment mounting portion A that holds the vertical shaft portion 8a in a non-rotating state.

In addition, the vertical shaft portion 8a may be of a hexagonal shape in addition to a square shape, and is essentially provided with a pair of left and right surfaces that contact each of the inner surfaces of the plate-like bodies 10, 10 in a non-rotatable manner. Good to have.

In summary, the present invention provides the above-mentioned walking type mobile agricultural machine in which the vertical shaft portion 8a is formed to have a rectangular cross-section, and the inner surfaces of the plate-like bodies 10, 10 and the resistance rod mounting cylindrical body 7 are provided. and the outer surface of the vertical shaft portion 8a to form an attachment mounting portion A that comes into contact with three surfaces of the vertical shaft portion 8a to hold the vertical shaft portion 8a in a non-rotating state. It is characterized in that the shaft-shaped portion 8a is fixed to the plate-shaped bodies 10, 10 using bolts 11 that pass through the shaft-shaped part 8a together with the plate-shaped bodies 10, 10 on both sides thereof.

That is, with the vertical shaft portion 8a prevented from rotating by contacting the inner surfaces of the pair of left and right plate members 10 and the outer surface of the resistance rod mounting cylindrical member 7,
In addition, a pair of left and right plate-like bodies 1 can be attached using one bolt.
0 and 10, the vertical shaft portion can be connected to 8a can be connected in a non-rotatable state, which is a great practical advantage.

Further, since the vertical shaft portion 8a was brought into contact with the resistance rod mounting cylindrical body 7 to prevent rotation in the front-rear direction, for example, the vertical shaft portion 8a may be spaced apart from the cylindrical body 7. There is no need to use two bolts to prevent the vertical shaft portion 8a from rotating in the front-rear direction, unlike when arranging the resistance rod, and the use of the resistance rod mounting cylindrical body 7 reduces the number of bolts and assembly effort. It has the advantage of being wearable.

Note that although reference numerals are written in the claims section of the utility model registration for convenience of comparison with the drawings, the present invention is not limited to the structure of the attached drawings by such entry.
