The bracket 15 is rotatably installed on the housing body 20 by a hinge shaft coaxially with the crushing rotation body 30, and the housing body between the coupling bracket 15 and the housing body 20 ( A cylinder 19 for rotation of 20 may be installed.

In addition, a spray nozzle (not shown) may be installed in the housing support 11 to spray water to a portion where the crushing operation is performed by the bits of the crushing rotating body 30 . The injection nozzle may be connected to a water supply unit for supplying water by a supply pipe.

The action of the vibrating rotary ripper according to the present invention configured as described above is as follows.

In order to crush an excavation or arm using the vibrating rotary ripper 10 according to the present invention, the coupling bracket 15 installed on the housing body 20 is coupled to a boom of a construction machine, for example, a boom of an excavator. By rotating the housing body 20 using the tilting unit 18 on the coupling bracket 15, the crushing rotating body 30 is adjusted to a position for excavation or crushing. At this time, the tilting unit 18 can be made by driving the hydraulic cylinder 19 coupled with the coupling bracket 15.

In this process, the crushing rotating body 30 is rotated using the rotary driving unit 70 of the rotary driving unit 90 of the crushing rotating body 30, and the vibration generating unit 60 is operated to crush the rotating body ( 30) to generate vibration in the direction of rotation or reverse rotation.

The rotation of the crushing rotation body 30 is made by the rotation drive unit 70 of the rotation drive unit 90 of the crushing rotation body, which is one of the second drive motors 75 and 76 of the rotation drive unit 70. When at least one of the support gears 73 and 74 is rotated by driving at least one of them, the ring gear 71 and 72 meshed with it is rotated so that the crushing rotating body 30 is formed with respect to the housing body 20 will rotate

In addition, the generation of vibration by the vibration generating unit 60 drives the first driving motor 62 of the vibration generating unit 60, and the first driving shaft 63 connected to the rotating shaft 62a of the first driving motor 62. ), the first and second driven gears 67 and 67' arranged radially, that is, crosswise, are sequentially rotated by the first drive gear 64 installed at the end thereof.

In this way, the eccentric weights 69 and 69' installed on the first and second driven gears 67 and 67' or the first and second eccentric rotation shafts 66 and 66' rotate, thereby generating vibration. do.

The vibration generated in this way rotates in a state in which the eccentric parts 69a and 69'a of the eccentric weights 69 and 69' are aligned so that they correspond to each other and face each other around the rotation axis. It is made strong in the rotation direction and the reverse rotation direction of the rotating body (30).

In more detail, as the eccentric weights 69 and 69' rotate, the vibration in the radial direction and the center direction of the crushing rotating body 30 is the crushing rotating body 30 as shown in FIG. Since the eccentric parts (69a) (69'a) of the eccentric weights (69) (69') rotating around the rotation center of the center are located on the corresponding side, the vibration energy in the radial direction is offset and extinguished.

In addition, as the first driving shaft 63 and the first driving gear 64 installed at the end thereof rotate by the first driving motor 72, the eccentric parts 69a and 69 of the eccentric weights 69 and 69' When 'a) is positioned in the rotational direction, as shown in FIG. 5, kinetic energy, that is, vibrational energy according to the rotation of the eccentric weight acts in the rotational direction of the crushing rotating body 30. Therefore, the excitation force according to the vibration acts on the bit 40 installed in the rotating crushing body 30, thereby increasing the crushing force or excavation force of the arm. In this process, the elastic members 81 and 82 of the elastic support 80 may provide excitation force acting in the rotational direction while extending in the rotational direction.

When the vibration generating unit 60 applies an excitation force in the opposite direction of the rotational direction, that is, as shown in FIG. 6, the eccentric parts 69a and 69'a of the eccentric weights 69 and 69' When is located at a position in the reverse rotation direction, the vibration energy acts in the reverse rotation direction of the crushing rotating body (30). On the other hand, each ring gear 71, 72 of the rotary drive unit 70 of the rotary drive unit 90 is supported by elastic support members 81, 82 installed on both sides of the crushing rotary body 30. , After the elastic support members 81 and 82 are stretched by the rotational force acting in the reverse rotational direction, when the vibration acts in the rotational direction again, the crushing rotation body 30 is excited by the restoring force in the rotational direction.

Accordingly, during the excavation by the crushing rotating body 30 of the vibrating rotary ripper according to the present invention, during the crushing operation of the arm, the excitation force generated from the vibration generating unit 60 acts in the rotational direction of the crushing rotating body 30. In the reverse rotation direction of the crushing rotation body 30, the excitation force is applied by the reaction force of the elastic support members 81 and 82, so the excitation force is applied to the bit 40 installed on the outer circumferential surface of the crushing rotation body 30. That is, the part excavated by the bit 40 acts as a striking force.

Due to this action, the vibrating rotary ripper can maximize work efficiency such as tunnel excavation, arm crushing, and face grinding.

On the other hand, when excavating or crushing the arm, the arm unit 100 installed in the gap for crushing, that is, the crushing rotating body 300, is inserted into the part for crushing. Since the shell arm cylinder 101 of the arm arm unit 100 is installed in the width direction of the crushing rotating body 300, the crushing rotating body 300 is inserted into the gap of the arm for crushing. A groove for inserting the arm arm unit 100 may be formed during the arm crushing process by the crushing rotation unit 300 .

In a state where the crushing rotating fluid 300 is inserted into the gap, hydraulic oil is supplied to the halam cylinder 101 using a hydraulic pressure supply unit. In this way, as shown in FIG. 8, the first and second pistons 104 and 105 move along the cylinder body 102 in the opposite outward direction, and the first and second rods 104a installed therein (105a) presses the arms on both sides in the direction of crushing based on the gap to crush the arms.

While the vibrating rotary ripper 10 performs the above-mentioned excavation work and arm crushing work, the vibration generated from the vibration generating unit and the vibration caused by the reaction force acting from the workpiece are caused by the housing support 11 and the housing body. It is absorbed by the buffer member 51 of the vibration dampening unit 50 installed between the 20, and vibration can be prevented from being transmitted from the housing main body 20 to the housing support 11 and the boom.

As described above, the vibration rotary ripper according to the present invention can increase the excavation and crushing force by providing an excitation force by the vibration generating unit in the rotation direction and the reverse rotation direction of the crushing rotation body 30.

Although the present invention has been described with reference to the embodiments shown in the drawings, this is only exemplary, and those skilled in the art will understand that various modifications and equivalent other embodiments are possible therefrom. Therefore, the true technical protection scope of the present invention should be determined by the technical spirit of the attached registered claims.
