Description

Technical Field

[0001] This utility model relates to the field of crushing equipment and tools, and more specifically, to a multi-functional crushing tool. Background Technology

[0002] A crusher is an attachment mounted on an excavator or other construction machinery for crushing hard materials such as rock, concrete, and asphalt. Driven by a hydraulic system, it uses high-frequency impact force to crush materials into smaller pieces and is widely used in mining, building demolition, road construction, tunnel engineering, disaster relief, and other fields. In existing technology, the functionality of crushers is highly dependent on a single attachment (hydraulic breaker), resulting in a limited operating mode. Current crushers can only perform single crushing operations and cannot adapt to diverse tasks such as material clamping and debris clearing, leading to low equipment utilization. If other operations are required, the attachment must be changed, significantly increasing downtime and adding to operational complexity and cost. Utility Model Content

[0003] The purpose of this invention is to provide a multifunctional crushing tool to solve the problems of single function, low operating efficiency, and chaotic site conditions in existing technologies. By integrating multiple functions, it reduces the frequency of attachment replacement, improves operating efficiency, reduces the risk of equipment damage, and improves site management.

[0005] A multi-functional crushing implement includes a boom, a crushing hammer mounted on the boom, a clamping arm hinged to one side of the crushing hammer, a hydraulic cylinder mounted on the boom, the hydraulic cylinder being connected to the clamping arm, and the hydraulic cylinder driving the clamping arm to open and close.

[0006] Furthermore, the clamping arm includes a mounting frame, one end of which has a shaft hole and the other end is fixed with a clamping claw; the mounting frame is hinged to the stick through the shaft hole.

[0007] Furthermore, the inner side of the gripper is provided with serrations.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] This invention enables multiple functions such as crushing, gripping, transporting, hooking, and gathering, reducing attachment change time and significantly improving work efficiency. The multi-functional clamping arm prevents the breaker hammer from performing non-crushing operations, extending equipment lifespan. The multi-functional crusher reduces the number of devices on the work site, making the site cleaner, while also reducing equipment purchase and maintenance costs and improving equipment utilization.

[0020] To enable those skilled in the art to better understand the technical solution of this utility model, the technical solution of this utility model will be clearly and completely described below with reference to the accompanying drawings. Based on the embodiments in this application, other similar embodiments obtained by those skilled in the art without creative effort should all fall within the scope of protection of this application. Furthermore, the directional terms mentioned in the following embodiments, such as "up," "down," "left," and "right," are only for reference to the directions in the accompanying drawings. Therefore, the directional terms used are for illustrative purposes and not for limiting the creation of this utility model.

[0021] The present invention will be further described below with reference to the accompanying drawings.

[0022] Example 1: A multi-functional crushing machine, such as Figures 1-4As shown, the device includes a boom 1, on which a breaker hammer 2 is mounted. A clamping arm 4 is hinged to one side of the breaker hammer 2. A hydraulic cylinder 3 is mounted on the boom 1 and connected to the clamping arm 4. The hydraulic cylinder 3 drives the clamping arm 4 to open and close. The combined structure of the breaker hammer 2 and the clamping arm 4 allows a single unit to perform crushing, clamping, and gripping functions. The hydraulic cylinder 3 provides the power for operation, reducing the frequency of equipment replacement and improving work efficiency. It is especially suitable for multi-process continuous operation scenarios in confined spaces.

[0023] Example 2: A multi-functional crushing tool, the clamping arm 4 includes a mounting frame 45, one end of the mounting frame 45 is provided with a shaft hole 41, and the other end is fixed with a clamping claw; the mounting frame 45 is hinged to the stick 1 through the shaft hole 41.

[0024] The inner side of the gripper is equipped with serrations 43, which increases the friction coefficient and can stably grip irregularly shaped materials such as concrete fragments and steel bars, effectively preventing materials from slipping. The bottom of the outer side of the gripper is equipped with hooks 44, which are curved outwards. They can hook, sort and gather materials and debris on the ground. Especially in complex working environments, the front end of the hooks 44 is more flexible and can reach into gaps or corners. The curved shape and front end are used to hook out materials from corners or gaps.

[0025] The boom 1 and the mounting frame 45 are each equipped with a lug 42. The piston rod of the hydraulic cylinder 3 is hinged to the lug 42 in the middle of the mounting frame 45 via a pin. The bottom of the cylinder body of the hydraulic cylinder 3 is hinged to the lug 42 on the boom 1 via a pin. Gaskets are provided between the two lugs 42 and the hydraulic cylinder 3. A pin lock is installed on the pin, which is fixed with bolts and secured with double nuts to prevent loosening, thereby improving the vibration resistance of the pin.

[0026] A pressure-filled grease cup is provided at the hinge joint of the pin. The pressure-filled grease cup, together with lubricating grease, provides long-lasting lubrication, thus extending the service life of the hinge joint. Everything else is the same as in Example 1.

[0027] This invention allows the clamping arm 4 to be raised during crushing operations, such as... Figure 3 As shown, the presence of clamp arm 4 does not affect normal crushing operations and functions the same as conventional crushing equipment.

[0028] During material clamping or transfer operations, hydraulic cylinder 3 drives the opening and closing of clamping arm 4. The stroke and thrust of hydraulic cylinder 3 determine the opening and closing range and clamping force of clamping arm 4, which can be flexibly adjusted according to the shape and size of the material. When the large chamber of hydraulic cylinder 3 returns oil and the small chamber receives oil, the piston of hydraulic cylinder 3 retracts, pulling clamping arm 4 outward to open as... Figure 3 As shown, the material is released; when the large chamber of the hydraulic cylinder 3 receives oil and the small chamber receives oil, the piston of the hydraulic cylinder 3 extends, pushing the clamping arm 4 to close inward, forming a clamping space with the breaker 2 to grip the material, as shown. Figure 4The image shows the cross-sections of the multi-functional clamping arm 4 and the hydraulic breaker 2 in the clamping state.

[0029] During the cleaning process, the large chamber of hydraulic cylinder 3 receives oil, while the small chamber returns oil. The piston of hydraulic cylinder 3 extends, pushing the multi-functional clamping arm 4 inward to close. Figure 2 As shown, at this time, the hook claw 44 can be used to perform cleaning work such as hooking, grabbing, scraping, and pulling of materials.

[0030] The present invention has been described in detail above. The above description is only a preferred embodiment of the present invention and should not be construed as limiting the scope of the present invention. All equivalent changes and modifications made in accordance with the scope of this application should still fall within the scope of the present invention.
