DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a loading means for transporting a walking type working machine such as a walking type rice transplanter, a walking type cultivator, or a binder.

[0002]

2. Description of the Related Art For example, when a walk-behind rice transplanter is transported by a truck, it is general to adopt an upright attitude in which the body is inverted in order to increase the number of loads on a carrier. A loading means is adopted in which the front of the body is stably inverted by inserting the front part of the fuselage into a large styrofoam block having a recessed portion conforming to the shape of the front portion, and the entire styrofoam block is loaded on a truck bed.

[0003]

In the above-mentioned loading means made of a foam material, the styrene foam has an advantage that it serves as a cushioning member and it is difficult to transmit vibrations and impacts to the rice transplanter. There were difficulties when you did. In other words, when foamed materials are dissolved, toxic gas is emitted, and there is a problem in post-treatment that polluting problems occur whether they are incinerated or reused. Was desired. An object of the present invention is to develop a loading means for a walk-behind working machine that can be easily disposed after use and can be post-processed without causing any pollution problem.

[0004]

SUMMARY OF THE INVENTION In order to achieve the above object, the present invention is directed to a mounting portion formed on the left and right sides of a front end portion of an airframe and capable of being fixed to and removed from a mounting portion, and a traveling transmission case.

3 and 4, a pair of left and right mounting portions 1, 1, a pair of left and right grounding portions 2, 2, a pair of right and left mounting portions 3, 3, and a front and rear connecting member. A stand S of right and left integrated type composed of 4 and 5 is constituted. In this configuration, since the entire stand S is made of metal, there is no problem in terms of disposal and reuse when it is no longer needed, and the volume is smaller than in the case of styrofoam lump. In terms of advantages.

The mounting portion 1 is bolted to the left and right of the front end of the engine mounting frame 6 of the walk-behind rice transplanter, and the left and right drive shaft cases 7 of the transmission case M are received and supported by the mounting portion 3 to support the stand. By mounting S, the aircraft can be placed in an upright position in an inverted state.
Therefore, by fixing the grounding portion 2 to the bed with nails or bolts, the vehicle can be loaded on a truck with a stable standing posture with a wide grounding interval. Even when the stand is made of wood, it can be easily disposed of after reuse such as reuse or incineration.

[0007] The weight of the body is to be covered by a plurality of portions of the mounting portion 3 and the mounting portion 1. For example, compared to a structure supported only by the mounting portion 1, the load on each connecting point is reduced, and In addition to reducing the risk of deformation of the parts and the like, the support load is also distributed to the mounted part and the drive shaft case on the rice transplanter side,
The stress of the support portion can be reduced.

[0008]

Therefore, the structure in which the load can be dispersed and supported by the front end portion of the body frame and the drive shaft case portion can support the body stand without applying unreasonable stress such as deformation of the member, and can be used after the used body. Incineration and decomposition,
In addition, the disposal means such as reuse can be made easily and the pollution problem does not occur at all, and the loading means with the walk-behind work machine standing can be provided as a preferable one which is durable and has no environmental destruction.

Embodiments of the present invention will be described below with reference to the drawings. FIG. 5 shows a stand S for a walking rice transplanter. The stand S is configured by welding and integrating a mounting portion 1, a grounding portion 2, a mounting portion 3, and front and rear connecting portions 4 and 5. Except for the mounting portion 3 made of a square pipe, the stand S is made of an angle material and has a symmetrical shape.

The left and right grounding parts 2 and 2 are connected by the front and rear connecting parts 4 and 5.
The mounting portion 1 is fixed upright to the rear connecting portion 5, and the mounting portion 3 is fixed upright to the grounding portion 2. A mounting hole 1 a is formed in the mounting portion 1, and a receiving piece 3 a having a mounting surface that is recessed downward is formed at the upper end of the mounting portion 3. The grounding unit 2
One end is formed on an active portion 2a extending upward at an angle of about 80 degrees, and the other end is formed on a straight horizontal portion 2b.

FIGS. 2 to 4 show a state where the walking rice transplanter is standing upright using the stand S. FIG. That is, with the drive shaft case portion 7 projecting from the traveling transmission case M in the left-right direction mounted on the mounting portion 3, the mounting portions 1 are mounted on the left and right of the front of the mounting base 6 of the engine E. Hole 1
It is mounted on the body by bolting it on the left and right through a, and the inverted rice transplanting machine can be erected by the grounding of the right and left grounding parts 2 and 2. The stand S can be used to stand up even when the wheels 11, the chain case 12, the float 13, and the like are removed.

The loading procedure using the stand S is as follows. First, the stand S is mounted on the walking type rice transplanter in a normal posture with the action portion 2a facing down, and then the steering handle 8 is lifted upward to bend the grounding section 2. The part allows the aircraft to transition to an inverted position. In this standing posture, the front end of the protector 9 is arranged so as to contact the front connecting portion 4 via the cushion rubber 18, and the portion can support the body load. Incidentally, the front end of the protector 9 and the front connecting portion 4 may be configured to be opposed to each other with a slight gap so that the load can be supported by contacting the stand for the first time when the stand body is deformed.

Then, it is fixed to the wooden mounting table 10 attached to the truck bed with a nail 17 through an installation hole 2d formed before and after the ground portion 2. Vibrations and shocks during transportation are absorbed by the play between the nail 17 and the installation hole 2d, the deformation of the nail 17, and the like, so that it is difficult to transmit the vibration or shock to the rice transplanting machine.

Here, the detailed mounting structure between the mounting portion 1 and the body is, as shown in FIGS.
A protector 9 having a shape to be turned to the left and right of the weight 14 is fixed. The dimensions of the protector 9 are set so that the side surface of the protector 9 and the inner surface of the mounting portion 1 face each other. It is a structure that is bolted to the portion 9a. At this time, the receiving piece 3a is in a state of receiving and supporting the drive shaft case portion 7.

In some cases, a pedestal 15 is provided at the rear of the fuselage.
In some cases, the body may be stacked in a flat state while the body is slightly lowered forward, so that the installation hole 2d for the nail 17 is also formed at the tip of the working portion 2a.
For reference, FIG. 1 shows a walking type rice transplanter in a rice transplanting operation state where the stand S is not mounted, and 16 is a rice field.

[Alternative Embodiment] In the present embodiment, the left and right integrated stand S has been described.
As in the case of the stand shown in Japanese Patent No. 186, it is also possible to use a left-right divided structure in which the left and right stands are mounted and the stacking is performed first.

The mounting portion 1 may be attached to the fuselage by the engine mount 6 itself or another strength member such as a transmission case.
, And the protector 9, the mounting table 6, and the like are collectively referred to as “attached part A”. In the case where the chain case 12 is removed and transported, the drive shaft case 7
A stand S having a structure in which the mounting portion 3 is applied to the drive shaft itself supported by the drive shaft itself may be used.

In the claims, reference numerals are provided for convenience of comparison with the drawings, but the present invention is not limited to the configuration shown in the attached drawings.
