Description

Technical Field

[0001] The utility model relates to the technical field of crushers, in particular to a double-jaw crusher. Background Art

[0002] The double-jaw crusher is a common type of crushing equipment, primarily used for crushing various medium-hard ores. The double-jaw crusher achieves its crushing function through the interaction between the movable and stationary jaws. It is driven by an electric motor, which rotates the eccentric shaft via a pulley and V-belt, causing the movable jaw to periodically approach and move away from the stationary jaw, thereby squeezing and crushing the ore entering the crushing chamber. The double-jaw crusher primarily consists of a frame, movable jaw, stationary jaw, eccentric shaft, bearings, adjustment device, and spring safety device. The frame serves as the support for the entire machine, while the movable and stationary jaws are the core components of the crushing process, and the eccentric shaft drives the movable jaw. The double-jaw crusher boasts a high crushing ratio and produces a uniform product particle size, making it suitable for crushing ores of various hardnesses. It also features a simple structure, reliable operation, easy maintenance, and low operating costs.

[0003] The prior art provides a double-action jaw crusher (Announcement No.: CN213669444U), which solves the problem of cooling water remaining on the stone that cannot be solved in the prior art. A post-processing box is provided at the lower end of the device housing, and the post-processing box is fixedly connected to the device housing. A baffle is provided inside the post-processing box, and the baffle is fixedly connected to the post-processing box. A dryer is provided at the lower end of the baffle, and the dryer is fixedly connected to the post-processing box. A roller is provided at the lower end of the dryer, and a stepper motor is provided at the rear end of the roller, and the stepper motor is connected to the roller through a coupling. A connecting arm is provided on the roller, and a plurality of connecting arms are provided. A stirring plate is provided on the connecting arm, and the number of the stirring plates is set to be consistent with the number of connecting arms. An electric valve is provided at the lower end of the stirring plate, and the electric valve is fixedly connected to the post-processing box.

[0004] However, the device still has the following defects:

[0005] When the device is in use, if the shape of the sample is too large, the sample will not be able to enter the interior of the crusher. The overly large sample will be stuck in the feed port, causing the equipment to be blocked, and may even cause the equipment to overload, posing a safety hazard. Processing large samples requires more operating steps and more complicated processes, which increases the complexity of the operation. Therefore, we need to propose a double-jaw crusher.
