Description
Technical Field
[0001] This utility model relates to the field of dual-rotor sander technology, specifically a dual-rotor sander structure that is easy to install. Background Technology
[0002] In the production of sand and gravel aggregates in construction, mining, and other fields, the twin-rotor sand making machine, with its advantage of dual-rotor synergistic crushing, can effectively improve sand making efficiency and finished sand quality, making it one of the mainstream sand making equipment. However, existing twin-rotor sand making machines still have many problems that urgently need to be solved in structural design and practical application. In the design of the hammer assembly, the hammers and hammer rods of existing equipment are mostly fixedly connected, and the assembly of the hammer rods and fixed rods mostly relies on a single bolt for locking. This structure not only requires the bolts to be disassembled one by one when replacing the hammers, which is cumbersome and time-consuming, but also easily causes the hammers to shift during high-speed rotation due to loose bolts, affecting sand making accuracy and even posing safety hazards. Therefore, a new technical solution needs to be designed to solve these problems. Utility Model Content
[0003] The purpose of this utility model is to provide a conveniently installed dual-rotor sander structure to solve the problems mentioned in the background art.
[0004] To achieve the above objectives, this utility model provides the following technical solution: a conveniently installed dual-rotor sand making machine structure, comprising a sand making machine body, a drive box assembled at the front end of the sand making machine body, a linkage box assembled at the rear end of the sand making machine body, a sand making chamber opened inside the sand making machine body, and a dual-rotor mechanism assembled inside the sand making chamber; the dual-rotor mechanism includes two drive rotor shafts installed in the sand making chamber, a limiting disk a is installed at one end of the external of the drive rotor shaft, a limiting disk b is installed at the other end of the external of the drive rotor shaft, grinding discs are evenly and equidistantly installed between the limiting disk a and the limiting disk b, four mounting holes are opened along the axis of the sidewalls of the limiting disk a, the limiting disk b and the grinding discs, a fixing rod is installed in each mounting hole, a mounting cavity is provided between each pair of adjacent grinding discs, and a hammer assembly is located outside the fixing rod in the mounting cavity.
[0005] Preferably, the hammer assembly includes a hammer rod installed outside the fixed rod, a hammer head installed at the end of the hammer rod, a fixing hole opened on the lower side wall of the hammer rod, the hammer rod being sleeved on the outside of the fixed rod through the fixing hole, and a locking interface opened at the bottom of the fixing hole, the locking interface being locked by a locking mechanism.
[0006] Preferably, the snap-fit mechanism includes a snap-fit block installed on one side wall of the card interface and a snap-fit slot opened on the other side wall of the card interface, wherein the snap-fit block snaps into the snap-fit slot.
[0007] Preferably, the end of the balance slide bar is equipped with a roller, the inner walls on both sides of the locking block are provided with inclined convex surfaces, and the outer walls on both sides of the locking groove are provided with inclined concave surfaces, the inclined convex surfaces and the inclined concave surfaces cooperate with each other.
[0008] Preferably, the card block has a filling cavity inside, an arched elastic plate is installed inside the filling cavity, and the end of the card block has an arc surface.
[0009] Preferably, a linkage shaft a is installed on the left side inside the linkage box, a linkage shaft b is installed on the right side inside the drive box, a rotating rod a is installed at one end of the drive rotor shaft, the rotating rod a on one side of the drive rotor shaft is connected to the linkage shaft a, and the rotating rod b on the other side of the drive rotor shaft is connected to the linkage shaft b.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: The hammer assembly of this device adopts a dual assembly structure of "fixed hole sleeve + snap-fit mechanism limiting". The hammer rod can be directly sleeved onto the fixed rod through the fixed hole, and the initial installation can be completed without tools. The design of the inclined convex and concave surfaces of the snap-fit block and the snap-fit groove realizes the quick snap-fit positioning of the hammer rod, while the arched elastic plate provides continuous elastic support for the snap-fit block, ensuring stable snap-fit. During disassembly, only a reverse force needs to be applied to disengage the snap-fit block from the groove, which greatly simplifies the hammer replacement process. Compared with the traditional bolt fixing structure, it effectively reduces equipment downtime maintenance costs and improves production continuity. Attached Figure Description
