Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a transport vehicle, and more particularly to a transport vehicle configured to be able to attach a spreading device used for spreading fertilizer or the like.

In conventional transport vehicles, it is necessary to install a specially constructed conveyor or the like in order to supply the spray material placed on the loading platform to the dispersion device installed, resulting in a complex structure that makes it easy to Because the transport vehicle itself cannot be attached or detached or cannot be fitted with a supply device such as a conveyor, it has the disadvantage that it is difficult to use the transport vehicle itself as both the scattering vehicle and the traveling vehicle body of other work vehicles.

In view of these drawbacks of the conventional technology, the present invention provides a transportation system in which the spraying device is easily attached and detached and can be used as a normal transportation vehicle, and the material to be sprayed is automatically supplied to the spraying device. The purpose is to provide cars.

To achieve this purpose, a spreading device is attached to the lifting part of a lifting device that is detachably attached to the rear of the dump bed, and the inlet of the spreading device is attached so that it can be lowered to a position below the dump bed. The rear flap plate is configured to extend downward from the rear end to the rear end of the dump bed and the input port.

Because of this configuration, by raising the dump bed, the material loaded on the dump bed is automatically supplied to the material input port of the spreading device through the rear fan plate, so simply attach the spreading device. A spreading vehicle that automatically supplies the material to be spread to a spreading device can be constructed at low cost with a simple structure that only requires the following steps.

Since the lifting device can also be attached to another working device such as a tiller rotor, a versatile transport vehicle can be constructed, which is highly effective in practical use.

Hereinafter, embodiments will be described based on the drawings.

As shown in FIGS. 1 and 2, a handle 1,
and a driver's seat 2, as well as an engine 3, a hydraulic unit 4, and a transmission 5. A front vehicle body 7 is constructed by mounting a pair of left and right driving front wheels 6, and a cargo platform 8 is connected to a hydraulic cylinder 9. The rear vehicle body 11 is constructed by mounting a pair of left and right drive rear wheels 10 on an axis, and the front vehicle body 7 and the rear vehicle body 11 are pivoted relative to each other around a vertical axis P. A hydraulic cylinder 1 for a steering link is connected to the vehicle bodies 7 and 11 and extends and contracts according to the amount of operation of the steering wheel 1 as the handle 1 rotates.
2 are interlocked and connected to form a so-called foldable dump truck. And the mission 5
and a differential mechanism for the rear wheels 10 are connected to the front and rear vehicle bodies 7 and 1.
The two wheels are interlocked and connected via a rear wheel drive shaft 14 having a universal joint portion 13 that allows relative rotation around the vertical axis P of the rear wheels.

A hitch 15 is provided at the rear end of the vehicle body frame 11a of the rear vehicle body 11, and various attachment working machines such as a spreading device A, a tilling rotary, and a mower can be mounted on the hitch 15.
Mounted via the lifting device 17, the mission 5
The power is transmitted to the attachment work machine via the rear power extraction shaft, so that in addition to transportation work, various other work can be performed.

Therefore, in order to spread fertilizer or the like, the lifting device 17 is attached to the body frame 11a of the rear vehicle body 11, and the spreading device A is attached to the lifting device 17.
can be installed.

As shown in FIGS. 3 and 4, the elevating device 17 includes guide frames 2 on both sides of a bracket 21 that is detachably attached to the rear hitch 15.
2 and 22, respectively, and a sliding frame 23 of the lifting section is attached to the guide frame 22 so as to be able to slide up and down via a pair of idle rollers 24 attached to each side of the sliding frame 23. A hydraulic cylinder 25 is interlocked and connected between the moving frame 23 and the guide frame 22. Further, a pair of upper and lower attachment portions 2 for attaching an attachment work machine to the frame 23 are provided.
6 and 26 are installed in series, and the spraying device A is attached to this mounting portion 26.
The side engaging part is attached.

On the other hand, spraying device A, which is an attachment work machine,
An input port 27 with an upper opening is formed in the input port 27, and a rotary valve 29 is disposed below the input port 27 for discharging the sprayed material in fixed amounts. This rotary valve 29 is rotated by the power transmitted from the ground following wheels 30 of the spraying device A.

Also, in front of this spraying device A is the lifting device 17.
A mounting portion having a pin-shaped engagement portion for engaging and locking the mounting portion 26 is connected to the mounting portion 26 . The distance between the rear part of the loading platform and the entrance of the spraying device A due to these mounting parts is:
The upper side of the rear flap plate 8a of the loading platform 8 is set to reach the input port 17 when the rear flap plate 8a is rotated rearward and opened.

An auxiliary side plate 8b is integrally connected to this rear agitation plate 8a, and forms a conveyance path from the rear of the loading platform 8 to the input port 27 of the spraying device A, thereby preventing the spread material from spilling left and right. The cover 28 of the inlet 27 of the spraying device A is connected to the main body at the rear of the inlet 27 by a hinge, and the cover 28 is configured to stand almost vertically, so that the material to be spread is not exposed to the back of the spraying device A. This prevents spills.

Then, bending links 31, 3 are provided between the side plate 8b of the rear flap plate 8a and the vehicle body frame 11a.
2 is constructed, and its bending point P is located at the loading platform 8.
It is guided into the front and rear slide grooves 33 on the side,
Due to this link structure, as the loading platform 8 rises, the rear flap plate 8a is automatically swung open rearward, and conversely, as the loading platform 8 descends, the rear flap plate 8a
a is automatically oscillated to close.

Incidentally, the rotary valve 29 of the spraying device A is
The rotation may be driven by a hydraulic motor driven by a hydraulic pump provided in the front vehicle body 7.
