The eco-friendly rock crushing method using the vibrating rotary ripper according to the present invention configured as described above is described in more detail as follows.

In the crushing rotating body rotation step 110 of the eco-friendly arm crushing method 100 using the vibrating rotary ripper, the first and second support shafts 33 and 34 of the crushing rotating body 30 are rotated in the housing body 20 Possibly installed, made by the rotation drive unit 90 installed on the crushing rotating body 30 and the housing body 20. The rotation of the crushing rotation body 30 is performed by the crushing rotation body rotation step 110.

The rotation drive unit 90 for performing the crushing rotation body rotation step 110 is a rotation drive unit 70 for rotating the crushing rotation body 30, and the rotational force of the rotation drive unit 70 for the crushing In addition to transmitting to the rotating body 30, an elastic support unit 80 may be provided to transmit the excitation force generated from the vibration generating unit 60 in the rotational direction of the crushing rotating body 30. The elastic support portion 80 is a plurality of elastic elements arranged in the radial direction from the center of rotation of the crushing rotating body 30 on the first and second supporting plates 41 and 42 installed on both sides of the crushing rotating body 30, respectively. Members 81 and 82 are provided. The rotary drive unit 70 is supported by the elastic members 81 and 82, and the ring gears 71 and 72 and the ring gears 71 and 72 on both sides of the crushing rotating body 30, respectively. It is meshed with and is provided with support gears 73 and 74 rotated by a second driving motor installed in the housing body 20. In addition, the housing body 20 may be assembled without a support gear by installing a ring gear bearing.

The means for performing the crushing rotation body rotation step 110 is not limited to the above-described embodiment, and any structure for rotating the crushing rotation body is possible.

In the crushing rotating body vibration step 120, the arm is broken by the bit 40 by rotating the crushing rotating body in the rotational direction in the vibration generating unit 60 installed inside the crushing rotating body 30.

The vibration generating unit 60 for performing the crushing rotation body vibration step 120 is driven by the first driving motor 62 installed on the housing body 20 and is driven by the drum-type crushing rotation body 30 It can be made by the vibration generating unit 65 installed inside. As shown in FIG. 4, the vibration generating unit 65 is installed inside the crushing rotating body 30, and eccentric rotation shafts 66 arranged radially on both sides of the crushing rotating body 30 are installed. , A driven gear 67 is installed on each eccentric rotation shaft 66. The driven gear 67 installed on the eccentric rotation shaft 66 installed adjacent to the first driving gear 64 rotated by the first driving motor is meshed with the first driving gear 64, and radial therefrom. The driven gear 68 installed on the eccentric rotation shaft 66 arranged in meshes with the driven gear 67 adjacent thereto. In addition, eccentric weights 69 are installed on the driven gears 67 and 68 or the first eccentric rotation shaft 66 that rotates like the driven gears 67 and 68, respectively. The eccentric rotation shaft 66 installed in the crushing rotation body 30 is preferably installed in the vertical and horizontal directions with respect to the center of the crushing rotation body 30 to form a cross or a straight line. However, it is not limited thereto, and may be installed symmetrically with respect to the center of the crushing rotating body 30.

On the other hand, the eccentric parts 69a of the eccentric weights 69 arranged radially or crosswise are all arranged in the same rotational direction. As described above, since the eccentric part of the eccentric weight 69 is aligned in the rotational direction, the vibration generated by the vibration generating unit acts in the rotational direction and the reverse rotational direction.

In the crushing rotating body vibration step 120, vibration in the rotational direction of the crushing rotating body 30 drives the first driving motor 62 to drive the motor shaft 62a of the first driving motor 62 and By driving the connected first driving shaft 64a, driven gears 68 arranged radially, that is, crosswise, are rotated by a driving gear 64 installed at an end thereof. In this way, the eccentric weights 69 installed on the driven gear 68 or the eccentric rotation shaft 67 rotate, thereby generating vibration.

Since the vibration generated in this way rotates in a state in which the eccentric parts 69a of the eccentric weights 69 are aligned to face the rotational direction, the vibration is strongly performed in the rotational direction and the opposite direction of the rotational direction.

Explaining this in more detail, the vibration in the radial direction and the center direction of the crushing rotating body 30 as the eccentric weight 69 rotates is the eccentric weight rotating around the center of rotation of the crushing rotating body 30 as a starting point ( Since the eccentric part of 69) is located on the corresponding side, the vibration energy in the radial direction is offset and extinguished.

And as the first drive shaft 64a and the first drive gear 64 installed at the end thereof are rotated by the second drive motor 75, the eccentric portion 69a of the eccentric weight 69 is positioned in the direction of rotation. When, the kinetic energy according to the rotation of the eccentric weight, that is, the vibration energy acts in the direction of rotation of the crushing rotating body (30). Therefore, the excitation force according to the vibration acts on the bit 40 installed in the rotating crushing rotating body 30.

On the other hand, in the crushing rotating body reaction force regulation step 130, when the crushing rotating body 30 vibrates in the opposite direction to the rotational direction, the crushing rotating body is elastically supported to reduce the reaction force and the bit 40 is constant. After hitting, the inertial force in the direction of rotation is reduced.

In the crushing rotating body reaction force regulation step 130, when the vibration is applied by the vibration generating unit 60 in the direction opposite to the rotational direction, as shown in FIG. 2, the crushing rotating body driving unit 90 Since each ring gear 71, 72 of the rotary drive unit 70 is supported by elastic support members 81 installed on the support plate on both sides of the crushing rotating body 30, the elastic support members 81 are rotated in the direction of rotation. And after being stretched by the excitation force acting in the reverse rotation direction, the crushing rotation body 30 is excited by the rotation direction and the reverse direction by the restoring force.

Therefore, the amplitude according to the vibration of the crushing rotating body 30 in the rotational direction is regulated by the elastic support member 81.

In particular, in the reaction force regulation step 130 of the crushing rotating body, the bit 40 applying a striking force to the arm for crushing the arm when vibrating in the rotational direction of the crushing rotating body 30 reacts in the reverse direction in proportion to the striking force It works.

This reaction force acts on the crushing rotating body 30 as a rotational force in the reverse direction, and this acting force is extinguished while tensioning the crushing rotating body 30 and the elastic support member 81 installed on the support plate. This makes it possible to reduce vibration and noise generated as a reaction force to the striking force of the bit 40 generated during rock crushing.

The arm crushing step 140 is the arm 200 for crushing the bit 40 of the vibrating rotary ripper as described above, in a state in which the rotation and vibration of the crushing rotating body 30 installed on the outer circumferential surface are made. ) to crush the arm 200.

As shown in FIG. 5, in the shredding piece separation step 160, the bit 40 installed in the rotating shredding body 30 crushes the arm with vibration by the vibration generating unit to generate cracks and crushing ash. This step is to pull the part where the crack occurs due to the rotation of the whole 30 in the rotational direction so that the crushed pieces generated by the crack can be separated.

In this fragment separation step 160, since cracks are generated by the bit 40 and crushing fragments can be easily separated, the crushing effect of the arm can be increased.

In addition, in the arm crushing step 140, as shown in FIG. 6, the arm for crushing is crushed to a predetermined depth using the rotating and vibrating crushing rotating body 30 to form an inlet groove, that is, a groove, It may consist of or include a halam step 170 of crushing the arm by inserting and expanding the halam cylinder 101 constituting the halam unit 100 installed in the crushing rotating body 30 into the groove.

In the shaving step 170, since the shaving unit 100 is installed in the crushing rotary body 30, it is possible to perform crushing by shaving the arm 200 at a specific part in the process of performing the crushing operation.

As described above, in order to perform the arm crushing step, the tilting step 180 is performed by tilting the vibrating rotary ripper 10 mounted on the boom of the excavator in the left and right directions, thereby performing the bit 40 of the crushing rotating body 30 ) It is preferable to maintain an arbitrary angle at the crushing position of the arm 200.
