DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a dropping control vehicle, and more particularly, to a dropping control vehicle with a screw feeder configured to unload a vehicle by inclining a carrier.

[0002]

2. Description of the Related Art Conventionally, when paving a road with asphalt, it is often the case that asphalt is loaded on a bed and the bed is inclined to spray the asphalt on a road surface. However, because the asphalt is sticky, it may not be easy to spray it even if the bed is tilted. Means for facilitation were taken, but not enough.

[0003]

The width of the luggage carrier of a 2-ton dump truck is about 1.5 m. Therefore, when the sewage pipe is constructed, the width of the pavement is about 0.6 to 1 m. In the case of narrow spraying, it is not easy to spray a predetermined width even if an operator operates the shovel while riding on an inclined bed. Further, since the temperature of the asphalt to be sprayed is about 140 ° C. to 160 ° C., a low-temperature burn may be caused during the operation, and there is also a troublesome problem that requires attention in safety.

[0004] The present invention has been made in view of such circumstances,
It is an object of the present invention to provide a dropping control vehicle that can easily set a spray width and that can easily perform a uniform spraying operation and has improved safety.

[0005]

According to the present invention, means for solving the above-mentioned problems are constituted as follows. That is, at the rear of the loading platform configured to be inclined and unloaded, left and right screw feeders that are opened rearward are provided, and openings are opened inside the loading platform in each screw feeder, and each opening is opened. Are covered with lids that can be opened and closed, respectively.

[0006]

For example, when it is desired to unload only from the left screw feeder, if the left opening is opened and the right opening is closed with a lid, the loading bed is inclined to drive the screw feeder. The load can be supplied from the left opening into the left screw feeder, and the load can be unloaded only from the left screw feeder. Also, when unloading over the entire width of the loading platform, the left and right openings may be left open, and the unloading status can be easily set as needed, and the unloading operation can be easily performed with the screw feeder.・ It will be sure. For example, uniform spraying can be performed safely and reliably even with high adhesiveness and high temperature asphalt.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Preferred embodiments of a dropping control vehicle according to the present invention will be described below in detail with reference to the drawings. FIG. 4 is a side view of a dropping control vehicle 1 of 2 tons loading. A dropping control device 3 for asphalt spraying is provided at a rear portion of a loading platform 2 configured to be able to unload the vehicle at an angle. The dropping control device 3 is, as shown in FIGS.
Openings 7, 8 which can be opened and closed by a pair of left and right foldable lids 4, 5 and whose opening can be adjusted by a plate 6 for setting a supply amount are opened inside the inside of the inside. It has screw feeders 9 and 10 and the rear is open. The lid 4 or 5 is opened and closed, so that the screw feeders 9 and 10 can be opened from either the left or right screw feeder 9 or both. Even from 9 and 10, asphalt can be sprayed efficiently and uniformly.

More specifically, a motor 11 for driving the above screw feeders 9 and 10 is provided at an upper end of one end of the dropping control device 3 and is connected to a sprocket 12 and a chain 13 fixed to an output shaft thereof. The interlockingly connected sprockets 14 each have a screw blade 9a.
And 10a are fixedly connected to a common support shaft S for fixing the same, and both screw blades 9a and 10a can be rotationally driven by operating an operation panel provided in the driver's seat 15. It has become.

A base 11a on which the motor 11 is mounted.
(Refer to Fig. 1)
It is suspended so that the vertical position can be adjusted by 9 and 19, and the position is set by set screws 20 and 20,
The tension applied to the chain 13 can be adjusted appropriately.

One of the screw blades 9a is formed in a clockwise direction, and the other screw blade 10a is formed in a counterclockwise direction.
Asphalt can be scattered and supplied outward. Incidentally, the span of each of the screw feeders 9 and 10 is set to 750 mm, and when spraying with a relatively narrow width such as in sewer pipe work, only one of the screw feeders 9 or 10 needs to be driven.

Openings 7, 8 of each screw feeder 9, 10
The plate 6 for adjusting the opening degree is fixed to the front surface of the main body frame 16 by bolting (not shown) or the like so that the vertical position can be adjusted, and the supply amount of asphalt loaded on the loading platform 2 is set and set. It can be changed.

Lids 4, 5 for opening and closing the openings 7, 8
Is one of the two lid plates 4a, 4b and 5a, 5b,
5a and 5a are independently pivotally connected to the front edge of the main body frame 16 via hinges 18, respectively, and are folded over the upper portion of the main body frame 16 in two layers and the opening of each screw feeder 9 and 10 is opened. It can be set separately for two states, that is, a state in which the front surface is hung down at 7 and 8.

The operation procedure of the dropping control vehicle constructed as described above will be described. First, the width and position (left and right) of asphalt pavement are checked in advance, and the lid 4 is made to correspond to the pavement state. , 5 are opened and closed. For example, in the case where drainage work is performed on the left side of the road (in the traveling direction), when paving is performed only on the left side, the corresponding left lid 5 (right side in FIG. While being folded, the left lid 4 is suspended from the front of the opening 7.

Next, the asphalt is loaded on the loading platform 2 and heads toward the site.
When the 11 is activated, asphalt is supplied only from the opening 8 on the right side, and asphalt is sprayed only from the screw feeder 10 on the right side. In this case, the spraying operation can be completed very easily and reliably by remote control from the driver's seat 15 without the operator directly operating the sticky and high-temperature asphalt, and the workability is greatly improved. Pavement work that is uniform, stable and good without pavement can be performed. Moreover, there is an advantage that safety is improved.

As described above, the setting of the spraying state can be made extremely easily according to the pavement state, and a safe dropping control vehicle with good spraying workability can be obtained with an extremely simple configuration.

The configuration of the present invention is not limited to the embodiment. For example, each lid is configured to move up and down by the driving force of a motor, and can be locally operated by remote control from a driver's seat 15. The setting of the spraying state may be changed. In that case, each lid is formed of a single plate, and both ends of each plate are fixed to a slider screwed to a screw rod driven by a motor, and the periphery of the screw rod and the slider is fixed. What is necessary is just to cover with a cover plate, and to prevent adhesion of asphalt. Further, the motor can be used also as a motor for driving a screw feeder. In that case, a gear transmission mechanism or the like for interlocking the motor with each screw rod may be separately provided in the main body frame.

Further, the cargo to be sprayed is not limited to an adhesive material such as asphalt, but it is needless to say that sand or jar may be used.

[0018]

As described above, according to the dropping control vehicle of the present invention, a pair of left and right screw feeders opened rearward is provided at the rear of the loading platform configured to be unloaded at an angle. The opening of each screw feeder, which is opened inside the loading platform, is individually covered with an openable and closable lid, so that the spreading width of asphalt and other cargo can be easily set and uniform It can be easily performed and safety is improved.
