Abstract

PURPOSE:To make reasonable the operations of dismantling a house, etc., by performing the dismantlement and crushing and selection of the waste materials at the site using a crushing machine and a crane device, etc., equipped with a tip work attachment, which are mounted on the rear body of a truck. CONSTITUTION:A crushing machine 3, driving device 4 for it, crane device 5, and a clamshell bucket 6 as its tip attachment are mounted on the rear body of a truck, etc. Dismantlement of a house, etc., and grading of the ground are made using a caterpillared backhoe, and waste materials are put in by the bucket 6 into the hopper 13 of the crushing machine 3 while objects from dismantling are selected. Time waste materials are crushed by the crushing machine 3, dropped onto a selection conveyor 14, and transported backward. On the way thereof metals are separated by a magnetic sorting machine 15, and foreign matters such as plastics are selected off. The wood is crushed into chips, while concrete, stones, etc., are reused as aggregate. Thereby the waste materials can be utilized effectively, the volume of waste materials be lessened to lead to spare of the transport costs, and the dismantling efficiency be enhanced.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a mobile crushing apparatus, which was developed for the purpose of enabling disposal of waste materials generated mainly at the site of dismantling and leveling a house at each site.

[0002]

2. Description of the Related Art Conventional house dismantling is done by attaching a fork-shaped grip to the arm tip of a bucket yunbo and breaking it, and then disposing it as it is on a truck or dump while it is rough and bulky, or discarding it only with large timber such as pillars. Had been sorted and transported to the place where there was a stationary crusher for processing such as chipping. Therefore, the dismantled materials were variously mixed from wood, stone, concrete pieces to metals and plastics, and not only was it troublesome to transport, but the resource reuse rate was extremely low.

[0003]

In view of these points, the present invention aims to rationalize the dismantling work, reduce the transportation amount, and improve the reuse rate of resources.

[0004]

[Means for Solving the Problems] As a means for solving the problems, a mobile crushing device is provided, in which a crusher, a driving device therefor, a crane device, and a tip working attachment thereof are mounted on a truck bed. The truck bed also includes a trailer.

The crusher is used to cut wood chips, concrete,
It is a strong one that can withstand the aggregate formation of stone material, and a known screw blade triaxial roll type is preferable. Along with this, a magnetic separator for selecting metals, a conveyor for selecting plastics, etc. can be installed. It can be driven from an automobile engine, but in some cases, a stable output can be obtained by using a dedicated engine, generator, or the like.

When the crane device is used for demolition of a house, a fork grip is attached, and a bucket is used for excavating land, removing soil, leveling, and a clamshell bucket for transportation. Generally, a caterpillar Yumbo is used for demolition and leveling of a house, and the clamshell bucket of this equipment is used to sort the demolition materials while transporting them to the hopper of a crusher. Therefore, the tip working attachment is mainly a clamshell bucket or a grapple with about 6 blades.

[0007]

Since the mobile crushing apparatus of the present invention is mounted on a truck or the like, it is possible to bring the crusher to the site of demolishing a house, which enables not only dismantling work but also mainly sorting of dismantled objects. That is, wood can be immediately chipped, concrete or stone can be crushed and reused as an aggregate at the site, and if a crusher is equipped with a magnetic separator and a sorting conveyor, it is possible to sort metal and plastic at the site. Become.

1 is a side view, FIG. 2 is a plan view in which a crane is omitted, and FIG. 3 is a rear view. In this example, a sub-frame 2 is provided on a truck carrier main frame 1 for reinforcement, and a crusher 3, a driving device 4 thereof, a crane device 5 and a clamshell bucket 6 as an attachment at the tip thereof are mounted on the sub-frame 2. . The truck bed may be a towed trailer bed, but a front outrigger 7 and a rear outrigger 8 are provided on the bed to stabilize the crushing operation and the crane operation. The crusher 3 is provided directly above the rear outrigger 8.

The crusher 3 is a screw blade triaxial roll type,
Three crushing rolls 9 are arranged in an inverted triangle, and a coaxial roll shaft 10 is driven by a hydraulic motor 11 and a speed reducer 12 to crush the waste material fed from an upper hopper 13. The crushed waste material is provided with a sorting conveyor 14 provided below.
It drops up and is carried to the rear of the dolly. In the middle of this process, a magnetic separator 15 is provided to select metals, and other foreign materials such as plastic in the crushed material are selected.

The drive unit 4 of the crusher is located in the center of the bed,
Generator 17 driven by sub engine 16, hydraulic pump 1
8, A belt pulley 19 for transmitting power to the crane 5 and a speed reducer 20 are contained in one case. A hydraulic pump 18 is connected to a hydraulic motor 11 of the crusher 3 by a plurality of hydraulic pipes 21. The drive source may be a separate sub-engine 16 or a truck engine. In this case, the propeller shaft from the mission extracts rotational force to operate the generator 17 and hydraulic pump 18.

The crane device 5 is supported by a crane swivel post 22 provided directly above the front outrigger 7 behind the truck cab and a crane post 23 above the crane post 23. There is a lifting ramp 25. The main boom 26 and the second boom 27 are now rotatably attached by the hoisting cylinders 28, 29. Further, in order to secure a working radius and working height, a telescopic third boom 30, a fourth boom 31 and its telescopic cylinder 32 are provided from the second boom 27, and a boom cylinder 33 is provided on the boom top 33 via a rotator 34. And the clamshell bucket 6 is attached.

Crane tip attachments include a clamshell bucket 6 and a 6-blade grapple, a grip for opening and closing a fork, a grip for an excavating bucket or a combination of forks and buckets, and various work attachments such as magnets. Is available. These are exchanged depending on the application, but clamshell buckets, grapples and fork grips are effective for effective utilization of the crusher.

EFFECTS OF THE INVENTION Most of the debris and waste materials generated by the collapse of old houses and buildings are wood chips, concrete blocks, steel frames, and reinforcing bars. In particular, wood chips are bulky, and crushing chips of these chips not only reduces the volume, but can also be recycled into fuel, compost raw materials, and sometimes even pulp raw materials. Conventionally, concrete lumps could only be disposed of by landfill, but by crushing, they can be recycled into aggregates, metals can be recovered, and plastics can be effectively used by crushing and sorting.

As described above, since the waste material can be treated at the site of collapse of a house or the like, it is possible to greatly reduce the transportation cost and improve the resource recycling rate.
