Description

Technical Field

[0001] This utility model relates to the field of stone processing technology, and in particular to a stone waste crushing hammer. Background Technology

[0002] Stone is widely used in the construction industry. Waste is generated during the production of stone. This waste can be reused after secondary processing. Before the waste can be reused, it needs to be crushed to reduce its volume for easier subsequent processing.

[0003] Existing hydraulic breakers typically employ a one-piece design for the hammer rod and hammerhead, a design with significant drawbacks in practical use. When crushing hard materials such as stone waste, the hammerhead, as the component directly in contact with the material, is highly susceptible to wear or breakage. Because the hammer rod and hammerhead are rigidly connected, replacing the entire breaker assembly requires disassembly and replacement when the hammerhead is damaged. This process is not only cumbersome and time-consuming but also forces the undamaged hammer rod component to be scrapped. Furthermore, the complex connection between the internal drive mechanism and the hammer rod necessitates disassembly of precision components such as the hydraulic system during replacement, further increasing maintenance difficulty and costs.

[0019] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be understood that these descriptions are merely exemplary and not intended to limit the scope of this utility model. Furthermore, descriptions of well-known structures and technologies are omitted in the following description to avoid unnecessarily obscuring the concept of this utility model.

[0020] In the description of this utility model, it should be noted that the terms "upper," "lower," "inner," "outer," "front end," "rear end," "both ends," "one end," and "the other end," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used solely for the convenience of describing this utility model and for simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0021] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installed," "equipped with," and "connected," etc., should be interpreted broadly. For example, "connected" can be a fixed connection, such as welding, riveting, or bonding; it can also be a detachable connection, such as threaded connection, keyed connection, or pin connection; or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; or it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0022] like Figure 1-3 As shown, the present invention proposes a stone waste crushing hammer, which includes a main body 1 and a hammer rod 2. The bottom end of the main body 1 extends out from the hammer rod 2. The outer end of the hammer rod 2 is fixedly fitted with an installation sleeve 3. The bottom end of the installation sleeve 3 is provided with an installation post 4. The bottom end of the installation post 4 is provided with an installation groove. The hammer head 5 can be inserted into the installation groove. The installation groove is provided with a positioning component for positioning the hammer head 5. The installation post 4 is provided with a fixing component for fixing the hammer head 5.

[0023] Hammer rod 2 is part of the main body 1, namely the hammer rod 2 of the breaker mechanism. Since the breaker is existing technology, it will not be described in detail here.

[0024] This technical solution solves the problem of needing to replace the entire hammer head 5 when it is damaged, as is common in existing technologies, by incorporating a detachable hammer head 5 structure. Specifically, when the hammer head 5 is damaged, only the fixing and positioning components need to be disassembled to replace it, without replacing the entire hammer rod 2 structure. This reduces maintenance costs and improves replacement efficiency. The solution has advantages such as simple structure, convenient operation, and low maintenance costs.

[0025] Furthermore, this application also proposes that the positioning component includes a positioning rod 6 and a positioning block 7. A first groove is provided on the top wall of the mounting groove, and a sliding groove communicating with it is provided on the inner wall of the first groove. The positioning rod 6 is connected to the hammer head 5, and the end of the positioning rod 6 away from the hammer head 5 is connected to the positioning block 7. The positioning rod 6 slides into the first groove and is fitted against the inner wall of the first groove. The positioning block 7 is slidably disposed in the sliding groove.

[0026] Therefore, this technical solution achieves the initial positioning of the hammer head 5 through the sliding cooperation between the positioning rod 6 and the first groove. At the same time, the sliding of the positioning block 7 in the groove restricts the rotational freedom of the hammer head 5. When the hammer head 5 is installed, the positioning rod 6 slides along the first groove to the predetermined position, driving the positioning block 7 to move in the groove, thereby achieving the precise positioning of the hammer head 5.

[0027] Furthermore, this application also proposes that a second groove is provided on the inner wall of the first groove and communicates with it, the slide groove is communicated with the second groove, the positioning block 7 can extend into the second groove along with the positioning rod 6, the positioning block 7 can rotate with the positioning rod 6 to a position away from the slide groove, and the positioning block 7 can rotate to abut against the inner wall of the second groove.

[0028] This technical solution adds a second groove and optimizes the movement path of the positioning block 7. When needed, the positioning rod 6 and the positioning block 7 can be moved and extended into the second groove simultaneously. By rotating the positioning block 7, the positioning block 7 can slide within the second groove. When the positioning block 7 slides to a position not located in the slide groove, the slide groove cannot move up or down, thereby further limiting the positioning rod 6 and the positioning block 7, thus further positioning the hammer head 5. Furthermore, by rotating the positioning block 7 to abut against the inner wall of the second groove, the installation angle of the hammer head 5 can be further positioned.

[0029] Furthermore, this application also proposes that the fixing component includes a fixing rod 8, a first through hole is provided on the mounting column 4, the first through hole is connected to the first groove, the upper end of the hammer head 5 is provided with a second through hole connected to the first through hole, the fixing rod 8 is detachably installed in the first through hole through the mounting unit, and the fixing rod 8 passes through the second through hole and is attached to its inner wall.

[0030] Specifically, this technical solution achieves detachable fixing of the hammer head 5 through the cooperation of the fixing rod 8 and the mounting unit. When the hammer head 5 needs to be replaced, simply remove the mounting unit from the fixing rod 8, pull the fixing rod 8 out of the first through hole and the second through hole, and the hammer head 5 can be removed for replacement.

[0031] Furthermore, this application also proposes that the installation unit includes a limiting disc 9 and a threaded sleeve 10. The outer circumferential surface of one end of the fixing rod 8 is provided with an external thread. One end of the limiting disc 9 is coaxially connected to the limiting disc 9. The limiting disc 9 extends into the first through hole and can be moved to fit against the outer end of the hammer head 5. The threaded sleeve 10 is at the other end of the fixing rod 8 and extends into the first through hole. The threaded sleeve 10 is threadedly connected to the external thread and can be moved to fit against the hammer head 5.

[0032] Specifically, the limiting disc 9 is used to restrict the axial movement of the fixing rod 8, preventing the fixing rod 8 from coming out of the first through hole. The threaded sleeve 10 secures the fixing rod 8 through a threaded connection, and rotating the threaded sleeve 10 can adjust the tightness of the fixing rod 8. Thus, this technical solution, through the cooperation of the limiting disc 9 and the threaded sleeve 10, enables the quick installation and removal of the hammer head 5. When it is necessary to replace the hammer head 5, simply rotate the threaded sleeve 10 to loosen the fixing rod 8, and the hammer head 5 can be removed from the mounting slot.

[0033] Furthermore, this application also proposes that a rotating handle 11 is coaxially fixedly sleeved at one end of the threaded sleeve 10 away from the limiting disc 9. The rotating handle 11 is located outside the first through hole and can be moved to abut against the outer end of the mounting post 4.

[0034] Specifically, the rotating handle 11 and the threaded sleeve 10 are coaxially fixedly connected. The outer diameter of the rotating handle 11 is larger than that of the threaded sleeve 10, facilitating manual operation. Therefore, this technical solution, by adding the rotating handle 11, allows operators to install and disassemble the fixed components without the need for tools. The external design of the rotating handle 11 ensures ease of operation while avoiding interference with the internal structure.

[0035] It should be understood that the specific embodiments described above are merely illustrative or explanatory of the principles of this utility model and do not constitute a limitation thereof. Therefore, any modifications, equivalent substitutions, improvements, etc., made without departing from the spirit and scope of this utility model should be included within its protection scope. Furthermore, the appended claims are intended to cover all variations and modifications falling within the scope and boundaries of the appended claims, or equivalent forms of such scope and boundaries.
