Description

[Detailed description of the invention] [Industrial application field] The present invention relates to an unloader with a vertical screw conveyor that is equipped with a plurality of transport routes for landing multiple types of bulk materials (for example, coal and wheat). .

[Conventional technology and its problems]

Conventionally, as shown in Figure 8, in an unloader with a vertical screw conveyor, one system of boom conveyor 1 is used.
A vertical screw conveyor 14 with a chute facing the boom conveyor 11 is suspended from the tip of the boom 1 equipped with a boom 1. Only one conveyance route extending over the ground conveyor 21 was provided. For this reason, when unloading multiple types of bulk materials with one unloader, if the previously unloaded bulk materials remain in the transport route, this residue will be mixed in, so each time the handled materials are changed, It is necessary to clean the entire transportation route by washing with water for a long time, which makes it difficult to respond quickly.
The inconvenience of inefficient landing operations was unavoidable.

[Purpose of invention]

The present invention was devised to solve the above-mentioned conventional problems, and its purpose is to enable quick response to the unloading of multiple types of bulk products.

[Means for solving problems]

The unloader of the present invention has multiple systems of boom conveyors installed in parallel on the boom, and a vertical screw conveyor with a corresponding chute formed so as to face each boom conveyor can be attached and detached from the tip of the boom between the boom conveyors. It is characterized by being able to be hung.

〔Example〕

An embodiment of the present invention will be described below with reference to FIGS. 1 to 7.

In the figure, reference numeral 1 denotes a boom, which is pivotally attached to a revolving frame 3 on a traveling frame 2 and can be raised and lowered by a raising and lowering device 4. On both sides of the tip of the boom 1, support arms 5 extending toward the opposite side of the rotating frame 3 are protruded, and a bracket 6 is provided on the tip of the arm 5.

7 is a rectangular mounting frame;
A pin receiving part 8 that opens upward is provided at the center of the upper frame, mounting pieces 9 extending toward the front are provided at both ends of the upper frame, and a pin connecting part 1 is provided at the center of the lower frame.
0 is set.

At least the boom 1 and boom conveyors 11A and 11B on the boom 1, which will be described later, are inserted into the frame of the mounting frame 7, and the support arm 5
Mounting piece 9 is attached to pin 1 at the tip of bracket 6 at the tip.
2, and is rotatably mounted on the mounting frame 7.
The rod tips of a swing cylinder 13 rotatably attached to the base end of the support arm 5 are connected to both ends of the lower frame. For this reason, the mounting frame 7
is suspended from the tip of the boom 1 and is swung by a swing cylinder 13 at a predetermined angle or more about a pin 12 without interfering with the boom 1 or the boom conveyors 11A, 11B.

14A is a vertical screw conveyor for wheat, 14
B is a vertical screw conveyor for coal, both of which have the same structure, with hanging pins 15 and pin connecting parts 16 vertically separated at the upper end of the conveyor frame, and one side (for wheat and Shutes 17A and 17B are rotatably connected to the opposite sides (for coal) at positions concentric with the pin 12,
These chute 17A, 17B are secured to the boom 1 with bolts or the like after the screw conveyors 14A, 14B are attached to a mounting frame 7 prepared at the tip of the boom.

One of the vertical screw conveyors 14A and 14B (14A in FIGS. 3 to 5, 14B in FIG. 6) is attached to the mounting frame 7, and is attached to the tip of the boom 1 between the boom conveyors 11A and 11B. It is supported so as to be able to swing around a pin 12 within a long hole 18 provided, and a hanging pin 15 is seated and engaged with the pin receiving portion 8, and the pin connecting portions 10 and 16 are connected by a fixed pin 19. has been done.

The boom conveyors 11A and 11B are the boom 1
The conveyors 11A and 11B are arranged in parallel on the top.
The screw conveyors 14A, 1 are installed on the inlet side of the
The chute 17A and 17B of 4B are arranged facing each other.

Shutes 20A and 20B are provided in the rotating frame 3 and the traveling frame 2, and the output ends of the boom conveyors 11A and 11B are arranged in the chute 20A and 20B, respectively.

21A and 21B are ground conveyors, which are arranged in parallel on the traveling line of the traveling frame 2, and the conveyors 21A and 21B are provided with the above-mentioned chute 20A and 21B, respectively.
It is placed facing 20B.

In addition, one vertical screw conveyor 14A, 14B is removably suspended from the tip of the boom 1, and two boom conveyors 11A, 11B are attached correspondingly to the vertical screw conveyor 14A, 14B.
An example was explained in which two chute 20A, 20B and two ground conveyors 21A, 21B are provided, and the conveyance routes in the unloader are two systems, one for wheat and one for coal, but the number of conveyance routes is two. Needless to say, it is not limited to.

Furthermore, when replacing a vertical screw conveyor, if the boom tip structure is such that the joint plate 1A is removed as shown in Fig. 3, the boom tip will be able to stand on the pedestal 23 when the screw conveyor is being stored in an upright position. This is preferable because it can be viewed from the body of the screw conveyor.

[Effect]

When unloading wheat from the hold of the ship 22, the unloader is driven to the screw conveyor storage area and the hanging pin 15 of the vertical wheat screw conveyor 14A stored upright on the storage frame 23 is attached to the upper end of the mounting frame 7. The pin receiving portion 8 is seated and engaged, and the pin connecting portions 16 and 10 are connected by a fixing pin 19 to be attached to the mounting frame 7. This vertical wheat screw conveyor 14A has a mounting frame 7
It is suspended from the tip of the boom 1 via a swing cylinder 13, and is swingable by a swing cylinder 13. For this reason,
When the wheat vertical screw conveyor 14A is put into the ship's hold and the unloading operation is carried out, the wheat in the ship's hold is transferred to the chute 17 by the wheat vertical screw conveyor 14A.
A, the wheat is delivered to a boom conveyor 11A, and the wheat is continuously conveyed to a wheat storage or the like by this boom conveyor 11A, chute 20A, and ground conveyor 21A.

In addition, when unloading coal from another ship hold,
After returning the wheat vertical screw conveyor 14A to the storage frame 23 and reattaching the coal vertical screw conveyor 14B to the mounting frame 7 at the tip of the boom 1 in the reverse procedure to the above, the unloading operation is performed. The vertical coal screw conveyor 14B transports the coal in the hold via the chute 17B to the boom conveyor 11.
The coal is delivered to boom conveyor 11B.
The coal is continuously transported to a coal yard or the like by a chute 20B and a ground conveyor 21B.

[Effect of idea]

As described above, the present invention can transport multiple types of loose materials through different transport routes and prevent them from mixing, so even if there is residue in the transport route, cleaning to prevent mixing is possible. In addition, it is possible to easily and quickly respond to changes in bulk materials by simply replacing the vertical screw conveyor at the tip of the boom. Therefore, the landing work can be carried out without requiring a large amount of setup time, and the efficiency of the work can be greatly improved.
