Abstract
Description
Technical Field
[0001] This utility model relates to the field of mining crusher technology, and in particular to adjustable impact plate castings for mining crushers. Background Technology
[0002] Mining crushers are specialized equipment used to crush large pieces of ore or materials into smaller particles. They are widely used in mining, metallurgy, building materials, highways, railways, water conservancy and other fields. They are mainly composed of components such as casing, rotor, hammers, and liners. The high-speed rotating rotor impacts, compresses and bends the material to achieve crushing. The impact plate rebounds the ore that was initially struck by the hammers back into the crushing zone to achieve secondary crushing and improve crushing efficiency. When the equipment is subjected to excessive impact force (such as the introduction of non-crushable materials), the impact plate will automatically retract or rise to increase the discharge opening and discharge foreign objects to avoid equipment damage.
[0003] The existing technical solutions mentioned above have the following drawbacks: the hammer structure inside the existing impact plate is simple and lacks structures to help improve the crushing effect, resulting in low efficiency of crushing stones inside the impact plate.

A first hammer is installed inside the placement groove. The first hammer has an installation groove and a fixing groove inside. The inner wall of the first hammer has a slot and a sliding groove reserved on the outer side of the installation groove. A countersunk hole is reserved on the outer side of the first hammer. A second hammer is engaged inside the installation groove. An insert block is fixedly connected to the outer side of the second hammer.
[0007] By adopting the above technical solution, the hammer inside the original counter-attack plate is designed into two parts. The first hammer has a second hammer installed inside it. The hammer head of the second hammer has a semi-circular structure, which allows the second hammer to be snapped into place inside the first hammer. The second hammer is engaged with the sliding groove and slot inside the first hammer through the cooperation of the insert block on the outside of the second hammer. After engagement, the hammer rotates and is fixed by the mounting bolts. The structure is more robust. Even if the bolts loosen later, the second hammer will not fall off immediately. Instead, it will shake inside the equipment, causing abnormal noise and prompting the staff to carry out maintenance.

[0009] By adopting the above technical solution, the first hammer plate and the counterattack plate are installed. By limiting the position with the fixing block and the fixing groove, the connecting piece is passed through the counterattack plate and the first hammer plate. It can be limited and locked by the locking block, and then locked and fixed by the locking bolt. At the same time, in order to ensure the stability of the structure and prevent the existence of movement gap between the locking block and the connecting piece, a shim can be added. The size of the shim can be adjusted according to the actual situation to make the structure installation more stable.
[0010] Furthermore, an installation bolt is installed inside the countersunk hole, a limit block is fixedly connected to the outside of the first hammer, a limit hole is opened inside the body of the counterattack plate, and a threaded hole is reserved on the outside of the body of the counterattack plate.
[0011] By adopting the above technical solution, the second hammer plate can be installed and disassembled by installing bolts.
[0012] Furthermore, the insert and the slot are engaged, the insert is engaged inside the sliding groove and slidably connected with the sliding groove, the slot and the sliding groove are interconnected, the connector passes through the first hammer and the main body of the counter-attack plate and extends to the outside of the main body of the counter-attack plate, the mounting bolt passes through the countersunk hole and extends into the inside of the first hammer, and the mounting bolt and the second hammer are threadedly connected.
[0013] By adopting the above technical solution, the second hammer is first locked in place and then rotated to limit its movement, thus preventing the second hammer from suddenly falling out.
[0014] Furthermore, the locking bolt extends through the locking block and the pad into the interior of the threaded hole, the threaded hole and the locking bolt are threadedly connected, and the limiting block and the limiting hole are engaged.
[0015] By adopting the above technical solution, the stability of the hammer installation is improved.
[0016] In summary, the beneficial technical effects of this utility model are as follows:
[0017] The system employs a first hammer and a second hammer. The second hammer is added inside the first hammer. The second hammer is quickly installed through the cooperation of the insert block, slot, and sliding groove, and then fixed with mounting bolts. At the same time, the first hammer is engaged by the limiting block and limiting hole, then the fixing block is engaged with the fixing groove, and finally connected and engaged by the locking block and connecting piece. The stability of the connection is improved by adding a pad, thus enabling the rapid installation of the first hammer. The combination of two different hammers improves the crushing effect and makes it convenient to use. Attached Figure Description
