Description

FIELD OF THE INVENTION

This invention relates to a vibratory ripper, and more particularly, to a vibratory ripper having a rotating element that compensates for the change in length due to the rotation of at least one connecting element in order to support the vibrating body within a limited amplitude range, and thereby provide vibration to the vibrating body up and down.

BACKGROUND

In general, in order to crush large debris at a construction site, a steel peak of a hydraulic hammer is installed on the boom of a heavy construction machine, which hits large debris and crushes them. At the same time, since such a - usual - method of striking with a hydraulic hammer causes strong noise pollution, heavy construction machines with low noise and high efficiency are required. In addition, in the area covered only with hard rocks, these hard rocks are crushed using a hydraulic hammer. However, when a hammer is used in the case of soft rocks, soft rocks are not crushed, but drilled. Therefore, an aggregate is required that not only performs the simple operation of crushing large fragments like a hydraulic hammer, but also simultaneously digs into the soil, vibrating up and down like a hydraulic hammer, being equipped with a mounted dump blade for digging into the soil like an excavator.

MODES FOR CARRYING OUT THE INVENTION

In FIG. 1-9 depict possible embodiments of a vibratory ripper in accordance with this invention.

Turning to the drawings, it is noted that the vibrator 10 in accordance with the present invention includes a vibrating body 20, a main body 30 that provides support to the vibrating body 20, a support body 40 of the vibrating body that supports vibration of the vibrating body 20 with respect to the main body 30, and a ripper knife 100, which is mounted on the side of the lower surface of the vibrating body 20.

The main body 30 may have a portion 31 of the vibrational space of the vibrating body 10. As shown in FIG. 1, on the upper side or side surface of the main body 30, it is possible to form a support bracket 32 for articulating with working equipment, which may include first and second frame support elements 33 and 34, which extend on both sides, forming a portion 31 of the vibration space, and enclosing frame 35, which serve as a support for the first and second supporting elements 33 and 34 of the frame. The portion 31 of the vibrational space may not be fenced off in the main body 30. The main body 30 is not limited to the above-described embodiment and may be of any structure, in which case the vibrating body support unit 40 gives a support to the vibrating body 20 with the possibility of vibration.

The vibrating body 20 is an element whose support relative to the main body 30 is provided by the vibrating body support assembly 40 so that vibration occurs with a predetermined amplitude, and may further include a vibration generating assembly 200.

In the vibration generating unit 200, there are two rotating shafts installed in parallel in the housing, each of which has an eccentric load, and gears are mounted on both of them, which are engaged with the rotating shafts. Eccentric weights mounted on the drive shafts are mounted in the same direction relative to the rotating shafts to minimize vibration in the up and down directions. An actuator is installed in the housing, which drives at least one of the two drive shafts. A vibration generating unit having such a configuration is disclosed in a Korean patent filed and registered by the Applicant of this application with registration number 0878296.

As shown in FIG. 1-3, the vibrating body support assembly 40 is an element that supports the vibrating body 20 to vibrate with respect to the main body 30, and includes at least one rotating member 41 that is mounted on the vibrating body 20, and the first and the second connecting elements 50 and 60, one end of each of which is mounted for rotation from the upper or lower side from the center of rotation of the rotating element 41 to deviate from the center of rotation of the rotating element 41, and the other end of each of them mounted with the possibility of rotation on the main body 30.

The rotating element 41 can be mounted in a direction perpendicular to the direction of vibration of the vibrating body 20, and can be mounted on the upper and lower portions of the main body 30, appearing on a vertical center line. The rotating element 41 can pass through the vibrating body 20 in such a way that its ends protrude in both directions, and can be supported in bearings, smoothly rotating relative to the vibrating body 20 in the normal and reverse directions. In this case, it is preferable to use an eccentric bearing as a bearing.

By the way, the rotating element 41 may not pass through the vibrating body 20, but may be mounted on both corresponding side surfaces of the vibrating body 20. In this case, it is preferable to place the centers of the rotating elements 41 and 42 on the same axial line. In addition, as shown in FIG. 1, the rotating element 41 can be mounted on a separate bracket 21, which is formed on the upper side of the vibrating body 20. The drawings show that the rotating element 41 is mounted on the vibrating body 20. In addition, the rotating element 41 can be mounted on the main body 30, and the vibrating body and the rotating element can be connected by the first and second connecting elements, as described above.

The amplitude of the vibrating body 20 can be adjusted in accordance with the joint position of each of the first and second connecting elements 50 and 60, articulated on the upper side and lower side of the horizontal line drawn through the center of rotation of the rotating element 41, through the axis of the hinge. That is, when the vibrating body moves away from the first and second connecting elements 50 and 60 and the center of rotation of the rotating element 41 up or down, the amplitude of the vibrating body increases, and when the vibrating body approaches the first and second connecting elements 50 and 60 and the center of rotation of the rotating element 41, the amplitude of the vibrating body decreases.

As shown in FIG. 1-5, one end of each of the first and second connecting elements 50 and 60 of the support assembly 40 of the vibrating body can be rotatably mounted on the upper side and lower side from the center of rotation of the rotating element 41 using the second and fourth hinge axes 52 and 62. The other end of each of the first and second connecting elements 50 and 60 is rotatably mounted on the main body 30 using the first and third hinge axes 51 and 61. As shown in FIG. 4, the first and second connecting elements 50 and 60 can be installed maintaining their horizontal state without rotation. As shown in FIG. 5, the connection portion between the first connecting member 50 and the main body 30 by the first hinge axis 51 is higher than the connecting portion between the rotating member 41 and the second hinge axis 52, and the connecting portion between the second connecting member 60 and the main body 30 by the third axis 61 the hinge is located higher than the joint by means of the fourth axis 62 of the hinge on the lower side of the center of rotation of the rotating element 41.

In embodiments, the lengths of the first and second connecting elements 50 and 60 may not be the same with each other, but different from each other, taking into account the rotation angle of the rotating element 41 and the articulation positions of the first and second connecting elements 50 and 60.

As shown in FIG. 6 and 7, in a portion that is spaced a predetermined interval from the rotary member 41, for example, on the vertical lower side of the rotary member 41, a coupling adjustment member 300 may further be provided, both ends of which are rotatably coupled to the vibrating body 20 and the main body 30 for adjusting to vibration. The connection adjusting element 300 and the connection portion of the vibrating body 20, which is rotatably connected to the hinge axis, may not be located on the vertical center line drawn through the center of the rotating element 41, taking into account the rotation of the vibrating body when the vibrating body 20 moves up and down .

The configuration of the coupling adjusting member 300 may provide vibration via a cylinder. As the cylinder, it is preferable to use a double-acting hydraulic cylinder. That is, the rod 302, which is connected to the piston 301 of the hydraulic cylinder, is rotatably mounted on the cultivator blade 100 by the hinge axis, and the cylinder 303, in which the piston 301 is mounted forward and backward, is rotatably mounted on the main body 30.

Although a double-acting hydraulic cylinder is described as an example of a coupling adjusting member 300, the present invention is not limited thereto, and the configuration of the coupling adjusting member 300 can be vibrated by a single-acting hydraulic cylinder.

As shown in FIG. 8, a rotating member may be mounted on each of the upper and lower sides of the vibrating body 20, and, as described above, the first and second connecting members 50 and 60 may be mounted on the rotating members 41 and 42, respectively.

At least one anti-vibration element 70 can be installed between the vibrating body 20 and the main body 30. In this case, the anti-vibration element 70 can provide support to the vibrating body 20 with respect to the main body, and an element separate from the main body 30 can support the anti-vibration element 70 .

An anti-vibration element 70 may be installed between the vibrating body 20 and the main body 30. The anti-vibration element 70 may be made of elastic rubber or formed by an elastic body, such as an elastic spring, but this is not a limiting feature. The anti-vibration element 70 can enhance the vibration generated by the vibration generating unit 200, and can provide a vibration return force when the vibrating body 20 vibrates. The anti-vibration element 70 can be installed between the side of the upper surface of the vibrating body 20 and the lower surface of the main body 30 and can be installed between the vibrating body 20 and the first supporting frame member 33, as well as between the vibrating body 20 and the second supporting frame member 34. The anti-vibration element 70 can be installed between the side of the upper surface of the vibrating body 20 and the lower surface of the main body 30, as well as between the vibrating body 20 and each of the first and second supporting frame elements 33 and 34.

By the way, as shown in FIG. 9, the main body 30 may further include a rotary member return portion 80 that returns the rotary member 41 to its original position when the rotary member 41 rotates. The rotary member return assembly 80 may include a housing 82 that is mounted on the main body 30 surrounding the rotary member support shaft 81, and an elastic member 83 that is installed between the outer circumferential surface of the rotary member support shaft 81 and the inner circumferential surface of the housing 82, restore rotation of the support shaft 81. In this case, the outer circumferential surface of the support shaft 81 can be made having a polygonal surface. The rotary member return assembly is not limited to the rotary member return assembly according to the above described embodiment, and can be shaped to include a return protrusion on the outer circumferential surface of the support shaft of the rotary member and an elastic spring between the housing and the return protrusion. When the above-described return assembly of the rotating member is provided, it is not necessary to install the anti-vibration member between the main body 30 and the vibrating body 20.

In FIG. 10-12 depict another embodiment of a vibratory ripper in accordance with this invention. In this embodiment, the same positions as in the previous embodiment indicate the same elements as in the previous embodiment.

Turning to these drawings, it is noted that the vibrator 10 in accordance with this invention includes a vibrating body 20, a main body 30, which gives support to the vibrating body 20, a node 40 of the support of the vibrating body, which supports the vibration of the vibrating body 20 relative to the main body 30, and a knife 100 of the cultivator, which is installed on the lower section of the node 40 of the support of the vibrating body. The vibrating body 20 is an element whose vibration relative to the main body 30 with a predetermined amplitude is supported by the vibrating body support assembly 40, as described in the previous embodiment, and may further include a vibration generating assembly 200.

As shown in FIG. 10-12, the support body 40 of the vibrating body is an element that supports the vibration of the vibrating body 20 relative to the main body 30 and includes at least one rotating element 41, which is mounted on the knife 100 of the cultivator, and the first and second connecting elements 50 and 60, one end of each of which is mounted to rotate from the upper or lower side of the center of rotation of the rotating element 41, being deviated from the center of rotation of the rotating element 41, and the other end of each of them is installed in the ability to rotate on the enclosing frame 35 of the main body 30. The configuration of each of the first and second connecting elements 50 and 60 can provide vibration with the help of a link element, and the first axis 51 of the hinge and the third axis 61 of the hinge that are mounted on the enclosing frame 35 can support it The design for mounting the rotatable member 41 may be the same as in the previous embodiment. That is, the rotating member 41 can be mounted in a direction perpendicular to the direction of vibration of the vibrating body 20, and can be mounted on the upper and lower portions of the main body 30, appearing on a vertical center line. The rotating element 41 can pass through the vibrating body 20 or the ripper knife 100 in such a way that its ends protrude in both directions, and can be supported in bearings, smoothly rotating relative to the vibrating body 20 in the normal and reverse directions. As shown in FIG. 12, it is preferable to use an eccentric bearing 45 as a bearing. By the way, the rotating member 41 can be rotatably mounted on the vibrating body 20.

An auxiliary housing 110 is installed on the upper side of the vibrating body 20, both sides of which are supported by the main body 30 by the first elastic support assembly 120, a connecting member 111 protrudes from the vibrating body 20 to the auxiliary housing 110, and the connection between the auxiliary housing 110 and the connecting member 111 may be achieved by means of a rotating shaft 113, which is rotatably mounted on the connecting element 111 in a direction parallel to the rotating element 41, both ends of which said shaft supported by the auxiliary chassis 110. The connecting member 111 may be supported by a bearing which is supported on the rotary shaft 113 and the bearing may be eccentric bearing. In this case, an eccentric bearing mounted on the rotary shaft 113 and supporting the coupling member 111 may limit the rotation of the rotary member 41 when the vibrating body 20 vibrates. However, it is possible to separately install a stop, which is not shown in the drawings and restricts the rotation of the rotating element.

Between the upper side of the connecting element 111 and the side of the upper surface of the auxiliary housing 110, a first elastic element 115 can be installed, which provides a reaction force, performs the operation of giving elastic support, and also absorbs shock. Between the side of the upper surface of the auxiliary casing 110 and the lower surface of the main body 30, a second elastic element 116 is installed which carries out the operation of giving elastic support, providing a reaction force, and also absorbing shock like the first elastic element 115 to which it corresponds. The configuration of each of the first and second elastic elements 115 and 116 may provide vibration using an element configured to provide an elastic force, such as an elastic rubber pad, shock absorber or spring.

Although not shown in the drawings, a second resilient member may be mounted on the side surface of the auxiliary body and its corresponding side surface of the main body. The side surface of the auxiliary body 110 and the side surface of the main body 30, on which the second elastic element is mounted, may be inclined.

As shown in FIG. 10 and 12, a connection adjusting member 117 may be installed between the auxiliary housing 110 and the main body 30a, which adjusts the auxiliary housing 110 to the main body 30. A hydraulic cylinder may be used as the adjusting connection of the member 117, but the present invention is not limited to this. You can also use a connecting element, shock absorber and actuator, which can move forward and backward.

In FIG. 13-14 depict another embodiment of a vibratory ripper in accordance with this invention. The same positions as in the previous embodiments, indicate the same elements as in the previous embodiments.

Turning to these drawings, it is noted that the vibrator 10 in accordance with this invention includes a vibrating body 20, a main body 30, which gives support to the vibrating body 20, a node 40 of the support of the vibrating body, which supports the vibration of the vibrating body 20 relative to the main body 30, and a knife 100 of the cultivator, which is installed on the lower section of the node 40 of the support of the vibrating body.

The vibrating body support assembly 40 is an element that vibrates the vibrating body 20 with respect to the main body 30, and a vibrating body bracket 131 is mounted on the upper side of the vibrating body 20, and one rotating element 41 is mounted on the vibrating body bracket 131. One end each of the first and second connecting elements 50 and 60 is mounted to rotate from the upper or lower side from the center of rotation of the rotating element 41 to deviate from the center of rotation of the rotating element 41, and the other end of each of the first and second connecting elements 50 and 60 is mounted for rotation on the main body 30. The rotating element 41 can be supported on the bracket 131 of the vibrating body by means of an eccentric bearing 45.

An auxiliary body 110 is mounted on the upper side of the vibrating body 20, which rests on the main body 30 by the first elastic support assembly 120, and a first elastic element 115 can be installed between the upper side of the vibrating body bracket 131 and the upper surface side of the auxiliary body 110, which provides force elasticity, performs the operation of giving elastic support, and also absorbs shock. Between the side of the upper surface of the auxiliary body 110 and the lower surface of the main body 30, or the side surface of the auxiliary body 110 and the side surface of the main body 30, a separate elastic element (not shown) is installed that performs the operation of imparting elastic support, providing a reaction force and also absorbing shock like the first elastic element 116 to which it corresponds. The configuration of each of the first and second elastic elements 115 and 116 may provide vibration using an element configured to provide an elastic force, such as an elastic rubber pad, shock absorber or spring.

In a portion that is spaced a predetermined interval from the rotating member 41, for example, on the vertical lower side of the rotating member 41, a connection adjusting member (not shown) can be further provided, both ends of which are rotatably connected to the vibrating body 20 and the main housing 30 and which adjusts to vibration. The configuration of the coupling adjusting member may provide vibration with a hydraulic cylinder and link as described above. Both ends of the connection adjusting element can be rotatably connected to the auxiliary body and the main body, and can also be connected to the ripper knife and the main body. The configuration of the coupling adjusting element may provide vibration via a cylinder, as described in previous embodiments.

A stopper 140 is mounted on the bracket 131 of the vibrating body or the auxiliary housing 110, which restricts the rotation of the rotating member 41. As shown in FIG. 13 and 14, the stopper 140 is in contact with at least one of the first connecting member 50 or the second connecting member 60 and limits the position of the rotating member 41 during rotation. However, the present invention is not limited to this, and the stopper 140 may be in contact with the extension portion 41a of the rotary member 41 and may limit the position of the rotary member 41 during rotation.

The stopper 140 may include a stopper shaft 141, which extends from the bracket 131 of the vibrating body or the auxiliary housing 110 to the first connecting member 50 or the upper side of the extension portion 41a of the rotary member 41, an elastic member 142 that is installed along the outer circumferential surface of the stopper shaft 141, and an outer circumferential ring 143, which is mounted on the outer circumferential surface of the elastic element 142. The outer circumferential ring may be made of a metal ring. Incidentally, the resilient member 142 may be eccentric or may have an eccentric bearing. However, the present invention is not limited to this, and the stopper can be of any design that gradually reduces the reaction force of the rotary member 41 during rotation and therefore can limit the position of the rotary member 41 during rotation. For example, the configuration of the stopper may include an elastic element, or said configuration may provide shock absorption using only the elastic element mounted on the outer circumferential surface of the shaft of the stopper.

In the vibratory ripper 10 in accordance with the present invention having the above configuration, the vibrating body 20 vibrates up and down due to the excitation of the vibration generating unit mounted on the vibrating body 20.

In the vibratory ripper 10 of the present invention, where a length compensating element is used and rotation is provided, the vibrating body 20 vibrates up and down due to the excitation of the vibration generating unit mounted on the vibrating body 20 or the vibration generating unit mounted on a working body coupled to the vibrating body .

During this process, the node 40 of the support of the vibrating body, which gives support to the vibrating body 20, operates as follows.

When the vibrating body 20 moves up and down under the action of the vibration generating unit, compensation is made for the magnitude of the length change due to the rotation of each of the ends of the first and second connecting elements 50 and 60, when the vibrating body 20 moves up and the rotating element 41 mounted on the vibrating body 20 or a knife 100 ripper rotates. That is, when the vibrating body 20, supported relative to the main body 30 by the first and second connecting elements 50 and 60, vibrates vertically upward, each of the ends of the first and second connecting elements 50 and 60 follows an arc path due to the rotation of the first and second connecting elements 50 and 60. In this case, the amount of movement of each of the ends of the first and second connecting elements 50 and 60 to the main body 30 is compensated by the rotation of the rotating element 41. Therefore, the vibrating body 20 can t to vibrate in the vibrational portion 31 of the main body 30. In particular, since the rotating member 41 is supported by the eccentric bearing 45, the change in position of each end is compensated when the first and second connecting elements 50 and 60 are rotated in an arc. That is, when the rotating element 41 rotates, each of the ends of the first and second connecting elements 50 and 60, which connect the main body 30 and the rotating element 41, absorbs - i.e. the rotating element 41 absorbs - changing the length of the connection section. When the vibrating body 20 moves downward from the extreme upper portion (top dead center) or moves from the extreme lower portion (bottom dead center) to the extreme upper portion, problems may occur due to the inertia of the vibrating body 20. The eccentric bearing 45 moves the position of the rotary member 41 and thereby compensates or conceals these problems.

In case the vibrating body 20 moves downward when the vibrating body 20 vibrates vertically downward, the first and second connecting elements 50 and 60 rotate in the opposite direction, and each of the ends of the first and second connecting elements 50 and 60 follows an arc path. Moreover, when the rotating element 41 rotates, the ends of the first and second connecting elements 50 and 60 move away from the main body 30, and the magnitude of the change caused by this is absorbed by the rotating element. Therefore, the vibrating body 20 vibrates up and down.

By the way, as shown in FIG. 10 and 15, the operation of the vibrator is also essentially the same as the operation in the previous embodiment. Since the rotating member 41 is mounted on the upper portion of the vibrating body 20, and the coupling adjusting member 300 is mounted on the ripper blade 100 or the auxiliary body 110, rotation of the main body can be prevented due to the external force exerted on the vibrating body 20 and the ripper blade 100, and since the stopper 140 which is in contact with the first connecting element 50 or the second connecting element is mounted on the auxiliary housing 110, the rotating portion of the rotating element 41 can be limited .

During this process, since the connecting member 111 mounted on the upper side of the vibrating body 20 is supported by the auxiliary housing 110 by a bearing, vibration distortion due to excessive rotation of the rotating member 41, which is supported by the first and second connecting members 50 and 60, can prevent when the vibrating body 20 moves up and down. In addition, since the auxiliary body 110 is supported on the main body 30 by the first elastic support assembly 120, vibration transmission of the vibrating body 20 to the main body 30 can be prevented.

In particular, since the first and second elastic elements 115 and 116 are installed between the auxiliary body 110 and the connecting element 111, as well as between the auxiliary body 110 and the main body 30, it is possible to reduce the transmission of vibration generated by the vibrating body 20 to the main body 20, and it is also possible prevent the transmission of vibration to the boom of the excavator, which supports the main body 30.

Since the coupling adjusting member 300 is mounted between the auxiliary body 110 and the main body 30, rotation of the ripper knife can be prevented when external force is applied to the vibrating body 20 and the ripper knife 100.

As described above, the vibration acting on the vibrating body 20 is transmitted to the ripper knife 100 and crushes large debris, and the vibration applied to the vibrating body 20 and the ripper knife 100 is concentrated on the end side of the ripper knife 100, and therefore, the crushing force of large fragments can be increased. and the power of excavation. In particular, when the vibrating body vibrates downward, an inertia force acts on the end of the ripper knife 100, due to the weight of the vibrating body 20 and the weight of the ripper knife 100, so that it is possible to further increase the crushing force.

Although several embodiments of the present invention are shown and described, they are illustrative only and it should be clear that those skilled in the art will be able to make various modifications and changes to the invention within the scope of its claims as defined by the claims. Therefore, the true scope of the claims of this invention should be determined according to the technical nature of the attached claims.
