[0030] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in combination with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments.

[0031] In existing rock breaking devices, the boom and forearm are usually driven by a boom cylinder, and the rock is impacted and crushed by a crushing head arranged on the forearm, which is well suitable for crushing construction operations on hard formations.

[0032] In order to further improve the efficiency of crushing construction, some embodiments of the present invention provide a vibrating crusher, referring to Figure 1 、 Figure 2 、 Figure 4 、 Figure 6 and Figure 7 , including a crushing head 11, the crushing head 11 can be hinged to the arm 21 and the crushing cylinder 22 respectively, and the arm 21 is hinged to the arm 23 and the arm cylinder 24 respectively.

[0033] The crushing head 11 is provided with a vibrator 12. When the vibrator 12 is working, it can drive the working unit composed of the crushing head and the forearm or the crushing head, the forearm and the upper arm to vibrate, and the rock is crushed by the vibration force of the working unit.

[0034] A vibrator is set on the crushing head. During the rock breaking operation, the exciting force generated by the vibrator can provide vibration force to the rock, thereby improving the rock crushing efficiency of the crusher.

[0035] In this embodiment, the exciter generated by the vibrator can drive the working unit composed of the crushing head and the small arm or the crushing head, the small arm and the large arm to vibrate, and the rock is vibrated and crushed by the vibration force of the working unit.

[0036] Conventional vibratory striking equipment usually drives the striking member to vibrate through a vibrator, and the striking vibration force is provided by the vibration of the striking member. In order to avoid the influence of vibration on other parts of the equipment, a vibration reduction structure is usually provided between the striking member and other parts of the equipment. Since the vibrator only drives the striking member to vibrate at high frequency, the vibration force that can be provided by the vibratory striking equipment in this manner is effective and cannot meet the needs of crushing hard formation rocks. Therefore, in this embodiment, the working unit consisting of the crushing head and the forearm, the crushing head, the forearm and the upper arm is driven to vibrate together by the exciting force. At this time, the force that can be generated by the overall vibration of the working unit is significantly greater than the force generated by the vibration of the crushing head alone, so that it can be better applied to the needs of crushing hard formation rocks.

[0037] In some embodiments, the exciting force generated by the vibrator 12 and the crushing force of the crushing head 11 are located in the same plane. Here, the exciting force of the vibrator and the crushing force of the crushing head are located in the same plane, which means that the direction of the exciting force generated by the vibrator and the direction of the crushing force of the crushing head are located in the same plane, so that the exciting force of the vibrator can provide an impact force to the crushing head in the direction of the crushing force.

[0038] In some embodiments, reference Figure 3 and Figure 5 The vibrator 12 includes a hydraulic motor 121 and an eccentric block 122. The eccentric block 122 can rotate under the drive of the hydraulic motor. The hydraulic motor 121 is fixedly arranged on the crushing head 11. The exciting force generated by the rotation of the eccentric block 122 is located in the same plane as the crushing force of the crushing head.

[0039] The hydraulic motor, as the driving component, drives the eccentric mass to rotate along its eccentric shaft. During this rotation, the eccentric shaft provides the vibrating impact force for the crushing head. Using a hydraulic motor as the driving component directly utilizes the hydraulic power of the rock breaking device to power the vibrator, facilitating its application in the vibrating crusher.

[0040] In some embodiments, a mounting hole cooperating with the vibrator is provided on the crushing head 11. The mounting hole is a through hole that passes through the crushing head. The vibrator is fixedly arranged in the mounting hole, which facilitates the fixed arrangement of the vibrator on the crushing head.

[0041] In some embodiments, the eccentric block 122 of the vibrator is disposed in the mounting hole to ensure that the exciting force generated by the eccentric block can be better located in the same plane as the crushing force of the crushing head.

[0042] The vibrator 12 also includes a sealed vibrating cylinder 123. A hydraulic motor 121 is mounted on one end of the vibrating cylinder and connected to an eccentric block within the cylinder. The vibrating cylinder 123 is fixedly mounted within a mounting hole. The vibrating cylinder is fitted into the mounting hole and the vibrator is fixed to the crushing head by welding or other means.

[0043] In some embodiments, the crushing head can adopt an integral structure or a split structure; taking the crushing head with a split structure as an example, refer to Figure 5 The crushing head 11 comprises a crushing head body 111 and a cutter head 112. The crushing head body 111 is provided with an accommodating cavity. One end of the cutter head 112 is fitted into the accommodating cavity and is detachably connected to the crushing head body via at least two pins 113. The vibrator 12 is provided on the crushing head body 111. This split-structure crushing head directly places the vibrator on the crushing head body without affecting the arrangement of the cutter head. The cutter head on the crushing head is also replaceable, providing the comprehensive performance of a vibrating crusher.

[0044] Two hinged parts 114 are usually provided on the crushing head or the crushing head body, and the two hinged parts 114 are used for hinged connection with the small arm and the crushing cylinder respectively.

[0045] When the crushing cylinder contracts, the crushing head 11 abuts against the arm 21, forming a single-piece structure. This integrated structure allows the vibrator's excitation force to be better transmitted to the arm, thereby effectively driving the vibration of the working unit comprised of the crushing head, arm, and / or boom. The abutment structure between the crushing head and arm can be similar to that described in CN209556998U.

[0046] On the other hand, the present invention also provides a rock breaking arm, referring to Figure 6 , including a small arm 21, a crushing cylinder 22 and a vibrating crusher 10, and the crushing head 11 is hinged to the small arm 21 and the crushing cylinder 22 respectively.

[0047] On the other hand, the present invention also provides a rock breaking device, referring to Figure 7 , including a boom 23, an arm cylinder 24 and a rock breaking arm. The arm 21 is hinged to the boom 23 and the arm cylinder 24 respectively. The boom is installed on the excavator main body and is driven by the boom cylinder (not shown in the figure).

[0048] During operation, the crushing head is adjusted to rest against the forearm through the crushing cylinder, so that the crushing cylinder and the forearm form a whole. The exciting force generated by the vibration of the vibrator drives the crushing head, forearm and upper arm to vibrate, and the rock is vibrated and broken through the vibration force.

[0049] In the description of the present invention, it should be noted that the terms "center", "up", "down", "left", "right", "vertical", "horizontal", "inside", "outside", etc. used to indicate the orientation or position relationship are based on the orientation or position relationship shown in the accompanying drawings, or are the orientation or position relationship in which the utility model product is usually placed when in use. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, they cannot be understood as a limitation on the present invention.

[0050] Furthermore, the use of terms such as "horizontal" and "vertical" in the description of this invention does not necessarily mean that the components must be absolutely horizontal or suspended, but rather that they can be slightly tilted. For example, "horizontal" simply means that the direction is more horizontal than "vertical," and does not mean that the structure must be completely horizontal, but rather that it can be slightly tilted.

[0051] It should also be noted that, in the description of this utility model, unless otherwise expressly specified or limited, the terms "disposed," "installed," "connected," and "connected" should be understood in a broad sense. For example, they can refer to fixed connections, detachable connections, or integral connections; mechanical connections, electrical connections; direct connections, indirect connections through an intermediate medium, and internal connections between two components. Those skilled in the art will understand the specific meanings of the above terms in this utility model based on the specific circumstances.

[0052] The above description is only a preferred embodiment of the present invention and does not limit the present invention in any form. Any simple modification or equivalent change made to the above embodiment based on the technical essence of the present invention falls within the scope of protection of the present invention.
