PROBLEM TO BE SOLVED: To dig up a subbase course by continuously carrying out crushing, more particularly cobbing work. SOLUTION: This civil engineering machine is constituted by mounting a frame 1 to a turning arm A disposed on the machine, turnably mounting a crushing drum 3 radially projectionly provided with crushing teeth 4 so as to expose and project part thereof at the frame 1, disposing a ripper 5 to dig up a road surface, etc., oppositely to the frame 1 so as to face the crushing drum 3 and deriving a crushing drum and shredding space for concrete lumps, etc., between the crushing drum 3 with the crushing teeth 4 and the ripper 5.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a civil engineering machine used at a building demolition site or the like, and more particularly to a multifunctional civil engineering machine that can perform various functions with one machine.

[0002]

2. Description of the Related Art Conventionally, an apparatus for crushing a concrete block attached to the tip of a hydraulic excavator or a bucket has opened and closed a crushing arm by a reciprocating mechanism of a cylinder. Therefore, since the operator operates the lever or the petal as desired, the degree of fatigue is large. In consideration of this point, there is a machine that mounts a tooth on the tip of a rotating arm and performs a cutting operation by the rotational movement of the rotating tooth, but the operation is merely a cutting operation. No consideration has been given to the treatment of earth removal. There is one in which one or a plurality of rotating teeth are provided in a bucket and shredded to some extent and received by the bucket and crushed, but this is merely crushing. It is necessary to rotate the bucket to discharge the shredded crushed material every time, which is disadvantageous in work.

[0003]

SUMMARY OF THE INVENTION An object of the present invention is to provide a versatile earth-moving machine capable of continuously performing crushing, in particular, subdivision work, excavating a roadbed, shortening work time, and efficiently processing. Is to provide.

[0004]

The means of the present invention are as follows.

[0005] A frame is attached to a rotating arm installed on the body, and a crushing drum in which crushing teeth are projected radially is rotatably mounted with a part of the frame being exposed and protruded, and is opposed to the crushing drum. A multi-function civil engineering machine that has a ripper that excavates the road surface on the frame, and crushes concrete pieces and shreds space between the crushing drum with crushing teeth and the ripper.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a perspective view showing an embodiment of a multifunctional earth-moving machine according to the present invention. 1 to 6 show a first example, FIGS. 7 and 8 show a second example, and FIGS. 9 and 10 show a third embodiment. The first example of FIGS. 1 to 6 is a U-shaped frame attached to a rotating arm A of a body B shown in FIG. 11 by a pin 20. The frame 1 moves freely with the movement of the rotating arm A. A hydraulic motor 2 serving as a pivot is attached to the front end of the frame 1, and a crushing drum 3 around which a plurality of crushing teeth 4 project radially is mounted so that a part thereof is exposed and protrudes from the frame 1. . Therefore, by the rotation of the crushing drum 3, some of the crushing drums 3 and the crushing teeth 4 crush concrete blocks and the like at positions protruding from the frame 1. Next, reference numeral 5 denotes a ripper which is detachably fixed to the base of the frame 1 by a pin 7 in opposition to the crushing drum 3, and crushes and shreds the space 6 between the crushing drum 3 and the ripper 5.
The ripper, which is commonly used, excavates a roadbed or the like, but the ripper according to the present invention not only excavates but also crushes the shredder and shredded space 6 as shown in FIG. The work of crushing with the ripper 5 can also be performed. Also, as shown in FIG. 2, the ripper 5 is composed of a plurality of thin plates 5 ′ (five in FIG. 2) assembled through a gap 5 ′ and discharges the crushed material shredded by the gap 5 ′. Although shown, the ripper may be a single thick ripper. FIG. 4 shows that the frame 1 is mounted so that the ripper 5 is on the upper side, and the crushing drum 3 can also perform the work of pressing and cutting the roadbed D or the like on which soil and other small pieces are scattered and accumulated by its own weight, Further, as shown in FIG. 6, the ripper 5 can be made to bite into the place where the earth and sand are deposited, and may be removed as shown in FIG.

FIGS. 7 and 8 show a second example.
In this embodiment, the crushing drum 3 is eccentric with respect to the hydraulic motor 2 for the purpose of further improving the crushing efficiency.
The effect of enlarging the rotating diameter is provided, and the crushing force can be further increased.

In the third example shown in FIGS. 9 and 10, the length of the crushing teeth 3 of the crushing drum 3 is changed as they are and the crushing teeth 4 are sequentially changed, so that the same eccentricity and effect as in FIG. It is like that.

[0009]

According to the present invention, crushing of concrete lumps and the like, in particular, cutting and digging of roadbeds and the like in which subdivision work is performed quickly and smoothly can be smoothly performed by one machine.
