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. The loading means is such that the front part of the body is stably inverted by inserting the front part of the fuselage into a large styrofoam block having a recess formed in accordance with the shape of the front part, 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, since toxic gas is emitted when the foam material is dissolved, there is a concern that pollution problems may occur even if the material is incinerated or reused. Was desired. An object of the present invention is to develop a loading means for a walk-behind work machine that can be easily disposed after use and has no pollution problem, and that a highly versatile stand is developed.

[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 detached from a mounting portion, and fixed to the mounting portion. The first grounding portion of the grounding portion is in a standing position in which the first grounding portion of the grounding portion is grounded in a posture in which the body is inverted by fixing the mounting portion to the mounted portion, and the body remains in a horizontal posture. The mounting portion is fixed to the grounding portion so that a stand for a walk-behind work machine is configured so that a flat stacked state in which the second grounding body portion of the grounding portion is grounded can be revealed. It is.

[0005]

Referring to FIGS. 6 and 7, a stand L is formed by welding a mounting portion 1 made of a bent iron plate and a grounding portion 2 made of a round pipe. In this configuration, since the entire stand L 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 that made of styrofoam lump. In terms of advantages. Then, as shown in FIGS. 2 and 3, the stands L and R are mounted with the grounding portions bent to the left and right of the front end of the engine mounting frame 4 of the walk-behind rice transplanter. In an upright standing state. As described above, when the apparatus is mounted in an upright state, the occupation ratio of the mounting area per machine can be reduced. Therefore, it is possible to mount a large number of walking-type working machines for the mounting area, or to mount them vertically while utilizing a small space between large machines. This makes it possible to transport a large number of machines with a small mounting area, facilitates mixing with a large machine, increases the efficiency of transportation, and reduces distribution costs. In addition, it can be mounted in a flat-stacked state. If such a mounting mode is selected, the machine center of gravity is lowered with respect to the ground contact portion, so that the vehicle can be transported in a more stable state. Even when the stand is made of wood, it can be easily reused or disposed of by incineration.

[0006]

According to the present invention, since the first grounding body portion and the second grounding body portion are provided with fixing portions and are directly fixed, a stand which can be attached to and detached from the strength member of the fuselage is constituted by the minimum necessary number of parts. In addition, because the grounding section is bent, it can be transported in a stable horizontal orientation, or it can be mounted in a small space in consideration of distribution costs. Since it can be transported in a combined form, a highly versatile stand could be obtained. And, by being composed of general structural materials, disposal such as incineration, disassembly, and reuse after use can be made easy and no pollution problem occurs at first.
The loading means in the state where the walking type working machine is standing can be provided in a preferable state without environmental destruction.

[0007]

Embodiments of the present invention will be described below with reference to the drawings. 6 to 8 show a stand L for a walking rice transplanter. This stand L is configured by welding a round pipe-made grounding portion 2 to a sheet metal mounting portion 1. The grounding portion 2 has one end formed in a second grounded body portion 2a bent upward at an angle of about 80 degrees, the other end formed in a straight first grounded body portion 2b, and The lower surface is slightly concave and rounded.

The mounting portion 1 is a leg member 1 having a U-shaped cross section which is welded to a concave inclined surface 2c formed at an intermediate portion of the grounding portion 2.
a, a tip member 1 having a U-shaped cross section and having a bolt hole 3 formed therein.
b is welded and fixed, and a contact member 1c welded across the leg member 1a and the distal end member 1b is disposed inside the leg member 1a. Further, the mounting portion 1 is fixed to the grounding portion 2 in a state where it is slightly inclined from 90 degrees to the second grounding body portion 2a side in a side view. Note that the stand L is a left-side stand, and provides a loading table function for one stand in combination with a stand R having a mirror-like shape (the structure is the same as the stand L).

FIG. 2 shows a state in which the walking rice transplanter is standing upright using the left and right stands L and R. That is, as shown in FIG. 4 and FIG. 5, the mounting part 1 is bolted to the left and right of the front part of the mounting base 4 of the engine E, so that the rice transplanting machine which is inverted by the grounding of the right and left grounding parts 2 and 2 stands upright. You can. In some cases, it is possible to stand using the stands L and R even when the wheels 11, the chain case 12, the float 13, and the like are removed.

The loading procedure using the left and right stands L and R is as follows.
First, the stands L and R are mounted on the walking type rice transplanter in the normal posture with the second grounding body portion 2a facing down, and then the control handle 5 is lifted upward to increase the size of the second grounding body portion 2a. The curved portion allows the aircraft to smoothly transition to the inverted posture. In this standing position, the step portion of the protector 8 contacts and is received by the contact member 1c. Then, it is fixed to the wooden mounting table 7 attached to the truck bed with the nail 6 through an installation hole 2d for fixing formed through the front and rear of the ground portion 2. Nail 6
The vibration and shock during transportation are absorbed by the backlash between the mounting hole 2d and the deformation of the nail 6 and the elastic deformation of the grounding portion 2,
Considered to be difficult to transmit to rice transplanters.

Here, as shown in FIG. 4, a detailed mounting structure of the mounting portion 1 and the body is such that a protector 8 having a shape to be turned right and left of a weight 9 is fixed to a front portion of the mounting table 4. In this state, the upper and lower surfaces of the side portion of the protector 8 are stopped just along the bent inner surface of the distal end member 1b, and the distal end member 1b is bolted to the nut portion 10 on the side surface of the protector 8 through the bolt hole 3. Structure. Also, in some cases, as shown in FIG.
Because the aircraft may be stacked in a horizontal position,
An installation hole 2d for the nail 6 is also formed at the tip of the action portion 2a. For reference, FIG. 1 shows a walking type rice transplanter in a rice transplanting operation state where the stands L and R are not mounted, and reference numeral 15 denotes a rice field.

[Another embodiment] The attachment portion 1 may be attached to the body by the engine mount 4 itself or other strength members, which are collectively referred to as an "machine frame F", and the protector 8 and the mount. The table 4 and the like are collectively referred to as a “mounted portion S”.

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.
