Description

[Detailed description of the invention] The present invention relates to a backhoe work vehicle in which a cover is provided on a swivel base equipped with a backhoe device, located above the left and right main frames thereof, and a driver's seat is provided above the cover. The purpose is to enable easy and safe suspension transportation of the entire vehicle body, and to make the structure for this purpose not to interfere with driving, etc.

Next, embodiments of the present invention will be described with reference to illustrative drawings.

As shown in FIG. 1, a backhoe work vehicle is equipped with a crawler type vehicle body 2 equipped with a dozer device 1 and a swivel platform 6 equipped with a backhoe device 3, a driving section 4, and a boarding operation section 5, and can also perform soil removal work. It is organized as follows.

As shown in FIG. 2, the boom 3a constituting the backhoe device 3 is located on the side where it is attached to the swivel base 6, and the front and back position can be adjusted as the boom 3a moves up and down.
A first locking device 7 for suspending the vehicle body is provided, and the shape of the locking device 7 is configured to be upwardly curved so that a hook, wire, etc. can be stably locked, and, Swivel base 6
As shown in FIG. 3, a second locking device 8 for suspending the vehicle body is provided on each of the left and right main frames 6a, and the upper end of the locking device 8 is inserted through a cover 9 above the main frame 6a. , is located between the cover 9 and the driver's seat 5a above it, and is configured to be exposed upward when the driver's seat 5a is rotated forward around the shaft 5b.

That is, as shown in FIG. 4, with the cover 5c above the driver's seat 5a removed, hanging wires 10 and the like are connected to the first and second locking tools 7 and 8, and the backhoe is lifted by the crane 11. It is constructed so that the entire work vehicle can be transported by hanging.

As shown in FIG. 5, the second locking device 8 is configured such that the upper end 8a of the second locking device 8 is moved upward by a pressing force caused by the lowering of the driver's seat 5a. Alternatively, as shown in FIG. 6, the upper end portion 8a of the second locking device 8 may be removably bolted to allow the lowering of the driver's seat 5a. At the same time, there is also a connecting hole 8c to a wire etc. in the lower part of the second locking tool 8.
Furthermore, if the driver's seat 5a is installed so that its vertical position can be changed, it is convenient because the driver's seat 5a can be lowered when there are obstacles overhead, such as in an orchard.
Further, the configuration shown in FIG. 5 above does not require the operation of the locking tool 8 and has excellent operability, and the configuration shown in FIG. 6 above is simple and inexpensive.

In summary, the present invention provides the above-mentioned backhoe work vehicle, in which the boom 3a constituting the backhoe device 3 is provided with a first structure for suspending the vehicle body, which is located on the side where the boom 3a is attached to the swivel base 6.
A locking tool 7 is provided on each of the main frames 6a, with the upper end portion 8a located between the cover 9 and the driver's seat 5a, and in an upward direction as the driver's seat 5a changes position. A feature is that a second locking tool 8 for suspending the vehicle body is provided in an exposed state.

That is, using the first and second locking tools 7 and 8,
By attaching wires, etc. for hanging on the crane to the backhoe work vehicle, the entire vehicle body can be easily suspended and transported, and the connection position of the wires, etc. to the vehicle body can be safely carried out without shifting during the suspension. Moreover, under normal conditions, the second locking device 8, which is located particularly near the driver's seat 5a,
Since it is located below the driver's seat 5a, there will be no inconvenient situation where the locking device 8 becomes a hindrance to boarding and driving.
It has also been improved in terms of operation.
