Description

Technical Field

[0001] This utility model relates to the technical field of cone crushers, and in particular to a cone crusher with an easily adjustable discharge port. Background Technology

[0002] The cone crusher is a crushing equipment used for crushing materials such as ores and rocks. It mainly consists of a frame, a crushing cone, an adjusting sleeve, and a transmission device. The equipment uses the crushing cone's gyratory motion under the action of the adjusting sleeve to squeeze, impact, and bend the material entering the crushing chamber, crushing it. The discharge port, as the channel for the crushed material to exit, directly affects the particle size of the crushed material. This utility model patent aims to achieve convenient adjustment of the discharge port through a specific structural design to adapt to the particle size requirements of different materials, thereby improving the equipment's operational flexibility and crushing efficiency.

[0003] In existing technologies, the discharge port of a cone crusher is relatively inconvenient to adjust during discharge operations, and the lifting and adjusting mechanism is not convenient enough. It is difficult to accurately control the length of the discharge port during adjustment, which can easily lead to over-adjustment or under-adjustment, resulting in the particle size of the crushed material not meeting the expected requirements. Furthermore, cleaning the inner wall of the discharge port and preventing blockage are inconvenient, and the anti-blocking mechanism is also inconvenient to use, which can easily cause difficulties in material discharge. At the same time, cone crushers tend to generate a lot of noise when crushing stone, and the noise reduction and sound insulation effects are not good enough. Therefore, we propose a cone crusher with an easily adjustable discharge port to solve the above problems. Utility Model Content
