Description

[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a small-sized earthworking vehicle mainly used for digging and discharging soil with relatively light load in the horticulture and construction industries.

[0002]

2. Description of the Related Art Conventionally, when a small backhoe is transported by being mounted on a truck such as a truck, the work vehicle itself uses a pair of left and right footboards which climbs on a carrier of the truck by itself. Was.

[0003]

[Problem to be Solved by the Invention] The unloading work of the step board itself is heavy labor, and a storage section for storing the step board in the transport vehicle is provided, and the step board is fixed to the storage section without play. Must be provided with fixtures, etc.
There were inconveniences such as high costs for mounting the work vehicle.
An object of the present invention is to enable work vehicle mounting work to be performed without requiring heavy labor, and to reduce the cost of mounting the work vehicle.

[0004]

In order to achieve the above object, the present invention is characterized in that a pair of left and right track frames of a crawler traveling device are provided with hanging brackets which can be extended and retracted laterally outside the fuselage. It is in the point.

[0005]

[Action] As shown in FIG. 2, the bracket 8, 8 provided on the track frame 7, 7 each of the pair of right and left crawler traveling device 1, 1 spanned wire W _1, the wire W ₁
If, then, the wire W ₂ hooked to the boom 5a rigs, hook a crane hook, mounting a work vehicle in the carrier of the truck by lifting with a crane.

[0006]

As a result of the above construction, the work vehicle can be mounted on the vehicle with a light work of laying wires, and the step board itself is not required, and accordingly, the step board is stored in the transport vehicle. It is not necessary to provide a storage section of the above, or to provide a fixing device or the like for fixing the footboard without looseness in the storage section, so that the cost for mounting the work vehicle can be reduced.

[0007]

DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the present invention will be described below with reference to the drawings. FIGS. 1 and 2 show a small-sized backhoe, which is composed of a pair of left and right traveling hydraulic motors M ₁ and M _1.
A pair of left and right crawler traveling device 1, 1 are respectively driven by a swivel base 2 to pivot driven by the vertical axis X around the turning hydraulic motor M ₂ to the top of the crawler traveling device 1, 1, the swivel deck A control unit 3 and a prime mover 4 arranged in the vehicle 2 and a boom 5a mounted on the front of the swivel 2;
It comprises a hydraulically driven excavator 5 comprising an arm 5b and a bucket 5c, and a hydraulically driven dozer device 6 arranged in front of the crawler traveling devices 1,1.

A hanging bracket 8 is provided on the laterally outer side of the body of the track frame 7 of the crawler traveling device 1 so as to be retractable to the laterally outer side of the body around the longitudinal axis P. The bracket 8 is provided with a hole 8a for inserting a wire, and a rubber projection 9 on the track frame 7 side, that is, a case of a traveling motor connected to an end of the track frame 7 in the hole 8a when the bracket 8 is stored in the body side. Rubber protrusions 9 provided on the lateral outer surface are configured to be engaged and fixable, and in a state of projecting laterally outward of the fuselage, contact with the front surface of the track frame 7 to restrict rearward rotation. Have been. Further, the bracket 8 is set to have such a protruding length that the wire W ₁ laid over the left and right brackets 8, 8 does not contact the lateral outer surface of the hood 10 covering the driving part 4. And boom 5
The arm cylinder mounting bracket 11a is provided with a wire insertion hole 11a through which a wire can be hooked over a hook of the crane.

When the small backhoe is mounted on a carrier bed of a carrier, a pair of left and right crawler traveling devices 1 and 1 are used.
Brackets 8 provided on each of the track frames 7, 7
8 spanned wire W _1, and the wire W _1, and, a wire W ₂ hooked to the arm cylinder bracket 11 for mounting the boom 5a rigs, hook a crane hook, a work vehicle Lift it with a crane and mount it on the carrier bed.

[Other Embodiments] The work vehicle may be an agricultural work vehicle such as a transport vehicle equipped with a crawler traveling device or a multipurpose management machine. Further, in the above embodiment, when hanging at the three points, the bracket 11 for attaching the arm cylinder of the boom 5a is provided with the hole 11a for inserting the wire. However, the wire is wound around the boom 5a and the wire is attached to the crane. You may comprise so that it may be hooked on a hook. Further, as shown in FIG. 4, the suspension bracket 8 may be configured to be freely retractable by a slide structure including a fixing bolt 12 and a long hole 13 on an end face of the track frame 7. Further, as shown in FIG. 5, it may be configured so as to be rotatable around the axis Y in the front-rear direction and to be able to move back and forth. In such a case, wire W ₁
When the hanging bracket 8 is turned upward, the inner end of the bracket 8
And is regulated by contacting the upper surface of the. Further, the track frames of the pair of right and left crawler traveling devices may be provided with hanging brackets at the front and rear, respectively, so as to be hung at four points.
