Description

[Detailed explanation of the idea] The present invention relates to improvements in conveyors.

At a quarry or a civil engineering construction site, when rocks and earth brought in by a dump truck are dumped onto a belt conveyor, for example, a large impact force is applied to the belt conveyor.

As a result, the belt conveyor may be damaged or require a more rigid structure.

In consideration of such a situation, a sturdy belt conveyor for dumping is separately provided, and after rocks and earth are dumped onto this belt, it is connected to a normal conveyor.

However, just as the preceding dump truck finished dumping,
Subsequent dump trucks had to wait, leading to a decline in work efficiency.

The present invention was devised in view of these conventional problems.

That is, the present invention divides the frame supporting the conveyor into fixed lengths in the conveyor transport direction, supports each divided frame via a shock absorber, and allows several dump trucks to move on the conveyor at once. Even if the frame is dumped, the impact force is buffered and the impact force does not affect other frames.

Hereinafter, details of the present invention will be explained with reference to embodiments shown in the drawings.

FIG. 1 is a diagram illustrating a belt conveyor as an example, taken transversely to the conveying direction.

In the figure, 1 is a belt placed on the impact carrier 2.

The impact carrier 2 has a bearing 4 fixed on a horizontal support 6.
is rotatably supported.

This horizontal beam 6 is made of an elastic body 9 (for example, rubber, etc.) on a frame I that is divided into fixed lengths depending on the inside of a vehicle such as a dump truck.
Supported through.

Further, each of the frames 7 divided into constant lengths is independently supported on the base frame 8 via an elastic body 10 (for example, a coil spring).

The return belt V has a horizontal beam 11 between the frames 7,
It is placed on a return impact carrier 3 which is rotatably supported by a bearing 5 fixed on this horizontal beam.

Reference numerals 13 and 14 are guide plates for guiding rocks or earth and sand dumped from a dump truck onto the belt 1.

FIG. 2 is a side view of the entire conveyor.

In the figure, the base frame 8 is divided into fixed lengths at 19.
A frame γ, which is independently supported on the top via an elastic body 10, is connected in the conveying direction of the conveyor.

The power sprocket 16 and the driving sprocket are connected by a chain or a belt, and the belt 1 is moved.

17 is a belt tensioning wheel operated by a cylinder 18.

2 is an impact carrier, and 3 is a return impact carrier.

Note that 13 and 14 in the figure are guide plates.

Normally, conveyors are connected with the upstream side of the conveyance facing up and the downstream side facing down, but this is not necessary with the conveyor of the present invention.

The operation of the embodiment configured as above will be described below.

First, when earth and sand are randomly dumped from several dump trucks, they are dumped onto the frame 7 divided into fixed lengths or onto the conveyor 1 at the joints of the frames 7.

At this time, the frames 7, which are independently supported on the foundation frame 8 via the elastic bodies 10, move independently depending on the load.

The independent movement of the frame 7 and the synergistic effect of the elastic body 9 buffer the impact force acting on the conveyor during dumping.

As detailed above, according to the present invention, the frame 7 is divided into fixed lengths and supported independently through elastic bodies.
Since the frames 7 are connected in the transport direction of the conveyor, when soil, etc. is dumped from a dump truck, each frame 7 moves independently according to the load, enabling random dumping of the dump truck, and each frame 7 also moves independently. Therefore, there is no influence of impact force during dumping on other frames installed in series, and the effect is similar to that of multiple conveyors connected in series.
This greatly improves work efficiency, eliminates the need for the conveyor to be damaged by impact force, and eliminates the need for a rigid structure.
In practical terms, the effect is extremely great.
