Description

Technical Field

[0001] This utility model belongs to the field of crusher hammer technology, and more specifically, it relates to a reversible crusher hammer. Background Technology

[0002] The hammerhead of a reversible crusher is a key and easily worn component; it is mainly used for impact crushing of materials. When the reversible crusher is working, the motor drives the rotor to rotate at high speed, and the hammerhead rotates with the rotor. After the material enters the crushing chamber, it will be violently impacted by the high-speed rotating hammerhead, causing the material to be crushed into the required particle size. The unique feature of the reversible crusher is that its rotor can rotate in both directions.

[0003] Existing reversible crusher hammers still have the following shortcomings:

[0004] While existing hammerheads allow for the replacement of counterweights, the locking springs can malfunction due to the impact of broken material powder, affecting safety. Furthermore, the counterweights on existing hammerheads are locked only by pins, resulting in poor stability after installation. Utility Model Content

[0005] To address the aforementioned technical problems, this utility model provides a reversible crusher hammer, which solves the problem that although existing hammers can replace the counterweight, the locking springs are susceptible to malfunction due to the influence of crushed material powder, affecting safety; and that the counterweights on existing hammers are locked only by pins, resulting in poor stability after installation.

[0006] The purpose and function of this reversible crusher hammer are achieved by the following specific technical means:

[0007] A reversible crusher hammer includes a hammer body; a rectangular groove-shaped mounting groove is formed on the top surface of the hammer body, and an auxiliary groove with a rectangular groove-shaped structure is formed on the right side of the top surface of the hammer body located in the mounting groove; a counterweight is engaged in the mounting groove, and a fixing hole for locking the counterweight is formed on the counterweight. The fixing hole is a circular hole-shaped structure, and the counterweight is a rectangular block-shaped structure. The outer wall of the counterweight is in contact with the inner wall of the mounting groove.

[0008] Furthermore, a locking rod slides on the hammer head body, passes through the auxiliary groove, and is inserted into the fixing hole, at which time the counterweight is in a locked state.

[0009] Furthermore, the left end of the locking rod is polished, and after polishing, the left end of the locking rod has an arc-shaped structure.

[0010] Furthermore, a stop is slidably mounted on the locking rod, and the stop is fixed to the locking rod by a fixing screw.

[0011] Furthermore, a spring is sleeved on the locking rod. The left end of the spring is in elastic contact with the right end face of the stop, and the right end of the spring is in elastic contact with the left end face of the inner wall of the auxiliary groove. Under the elastic push of the spring, the locking rod is in an inserted state with the fixing hole.

[0012] Furthermore, the stop is a T-shaped block structure, with the upper half of the stop covering the top of the auxiliary groove, at which point the auxiliary groove is sealed. A handle block is welded to the top surface of the stop, and the handle block is a rectangular block structure.

[0013] Furthermore, the locking rod, stop, spring, handle block, and fixing screw together form the locking assembly; a bearing groove is provided on the top surface of the hammer head body, and two disassembly holes are symmetrically provided at the bearing groove.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] In terms of counterweight adjustment, by snapping counterweight blocks of different densities into the mounting groove of the hammer body, the weight and impact force of the hammer can be flexibly adjusted according to the crushing requirements to meet diverse operating scenarios; the snapping design enhances the installation stability of the counterweight blocks and ensures reliable operation of the crushing work.

[0016] The locking assembly is ingeniously designed. The spring elastically pushes the locking rod to insert into the counterweight fixing hole, achieving a stable lock on the counterweight. Pushing the handle block can easily release the lock, facilitating counterweight replacement. The stop seat seals the auxiliary groove to prevent dust from entering and affecting the spring performance, thus preventing safety accidents and extending the service life of the assembly. It also facilitates the maintenance and replacement of the locking rod.

[0017] Regarding bearing installation and maintenance, the bearing groove on the hammer body is used to install bearings, and its connection with the crusher shaft effectively reduces wear. Symmetrically arranged disassembly holes allow the punch to precisely contact the bearing, enabling convenient disassembly and replacement of the bearing by striking the punch, significantly improving equipment maintenance efficiency and reducing maintenance difficulty and cost. The overall design optimizes the hammer's performance and maintenance convenience from multiple dimensions, enhancing the working efficiency and economy of the reversible crusher.
