Description

[Detailed description of the invention] Industrial application field This invention is a shear stacking machine that has a raking arm or a bucket and a tiltable slide-like main body equipped with a conveyor, and is connected to the shear stacking machine. It consists of a transport vehicle such as a shuttle car or a trolley, and the rock, earth, sand, rubble, ore, etc. (hereinafter referred to as "zuri") that has been scraped onto the edge of the conveyor with a scraping arm or bucket, is loaded on the conveyor and transported, and the transport vehicle Concerning earthmoving transport equipment for loading.

PRIOR ART AND ITS PROBLEMS Transport machines of this type are known and are mainly used in tunnels, tracks, quarries, etc. According to this type of transporter, the shear loading work is carried out by moving the shearer forward while scraping up the shear with a bucket or a scraping arm, placing it on a conveyor, and loading it onto a transport vehicle. Compared to the conventional method, which uses a loader such as a tractor shovel or shovel loader or a shovel type excavator, scoops up the shear with a bucket, swings it to the loading point, and releases it onto the transport vehicle. , has the advantage of being able to carry out shear stacking work continuously and efficiently, but one of the drawbacks is that the bending angle between the shear stacker and the transport vehicle connected to the shear stacker is restricted to a certain narrow angle. Therefore, when passing a curve, if the turning radius is small, it may not be possible to pass the curve. In other words, as shown by the dashed line in Figure 1, the main body 1 equipped with a conveyor has its tip raised to make it almost horizontal during normal running, so that the tip does not get stuck on the ground and become an obstacle to movement. However, since the long rear side of the shear stacker 2 is fitted into the transport vehicle, the rotation range of the main body 1 relative to the transport vehicle 3 is restricted to a narrow range α as shown in Fig. 2. As a result, the rear end of the main body gets stuck on the side wall of the transport vehicle on curves with a small turning radius, making it impossible to pass through the curve. Conventionally, when passing a curve is obstructed, the rod connecting the shear stacker and the transport vehicle is removed, and then the transport vehicle is moved using a towing vehicle such as a battery loco connected to the rear of the transport vehicle. During work, the transport vehicle moves forward as the shear stacker moves forward, so in particular, in cases such as a shuttle car, where the shear that falls from the end of the conveyor must always be loaded onto a predetermined location on the shuttle car, it is necessary to reconnect the two. Therefore, each time there is a problem in passing through a curve, it is necessary to remove or connect the rod.
Moreover, this connection operation requires alignment, which makes the operation more difficult. In addition, there is a risk of an accident due to a worker being caught between the loader and the transport vehicle, and a towing vehicle is also required.

During shear loading work, the shear loading machine is gradually moved away from or brought closer to the transport vehicle in order to evenly load the shear over the entire area of the transport vehicle.
In some cases, it may be desirable to gradually move the shear loading point on the transport vehicle, but in the conventional systems described above, it is not possible to change the shear loading point while the shear stacker and the transport vehicle are connected.

Means for Solving the Problems This invention attempts to solve the above problems by configuring a coupler that connects a stacker and a transport vehicle so that the distance between the two can be changed. That is, in the present invention, the coupler is composed of a cylinder, and the distance between the shear stacker and the transport vehicle can be changed by moving the piston rod of the cylinder back and forth.

The cylinder used here is preferably a hydraulic cylinder. This cylinder may directly connect the shear stacker and the transport vehicle, or the first rod connected to the shear stacker and the transport vehicle may be connected to each other.
The second rod may be connected to the first rod in a slidable manner.

Operation When the piston rod is advanced and the stacker 2 and the transport vehicle 3 are separated, the rear end of the main body 1 is pulled out in the direction of the arrow as shown in Fig. 3, allowing it to rotate within the transport vehicle. Range β increases. The range of rotation of the main body increases as the rear end of the main body is pulled out from the transport vehicle, and becomes able to freely rotate as the rear end of the main body moves away from the transport vehicle.

Gradually advancing or retracting the piston rod also moves the rear end of the main body, so that the loading location can also be gradually changed.

Embodiment FIG. 4 shows an example of a coupler, which includes a first cylindrical rod 5, a second rod 6 that is slidably inserted into the rod, and one end of which is connected to the first cylindrical rod. It consists of a hydraulic cylinder 7 whose other end is connected to a second cylindrical rod 6, and each rod 5 and 6 is connected to the shear stacker 2 and the transport vehicle 3 shown in FIG. They are connected by joints and can be rotated sideways and up and down.

Effects of the invention As described above, the earthworks transporting machine of this invention is designed so that the distance between the shear stacking machine and the transport vehicle connected to the shear stacking machine can be changed. Even when the rear side is fitted into the transport vehicle, it is possible to pass through curves without any trouble, and the loading location can also be changed.
