Description

Technical Field

[0001] The utility model relates to the field of stone crushing, in particular to a stone crushing device. Background Art

[0002] After searching Chinese patents, the publication number is: CN211838197U, an adjustable hammer crusher, including a shell, a feeding port is opened on the top of the shell, an inner lining plate is installed on the inner wall of the shell, a hammer crushing mechanism is installed on the rear side of the shell, and the front side of the hammer crushing mechanism passes through the shell and extends into the interior thereof. The utility model sets a hammer crushing mechanism, rotates the protective shell, takes out the protective shell, and then rotates the nut so that the nut is taken out from the surface of the threaded rod, and then takes the threaded rod out from the rotating rod and the connecting column, so that the connecting column can be taken out from the installation groove, and then replaces the hammers of different sizes, and installs the hammers again through the nut and the threaded rod. By replacing the hammers, not only is maintenance convenient, but also by adjusting the size of the hammers, the size of the crushed products can be different, and can be adjusted according to actual conditions, thereby improving the scope of use of the device and bringing great convenience to sand and gravel production work.

[0003] To sum up, it is not convenient to replace the hammer head of the crusher. The hammer head of the crusher is fixedly installed by a threaded rod and a nut. When replacing it, tools are needed to disassemble and assemble it. The disassembly and assembly process is relatively cumbersome, which increases the workload and reduces the efficiency of replacement. It also does not have a buffering function. The inner lining plate of the device is fixedly connected to the shell through a support block. During crushing, the stone will hit the inner lining plate when impacted, which will directly act on the shell with the impact force, reducing the service life of the inner lining plate, and will increase the vibration of the device, affecting the stability of the device. It also does not have a leveling function. When in use, the device is directly placed on the ground. If the ground is uneven, it will cause the device to shake, affecting the stability of the device. In order to solve the above problems, we propose a stone crushing device. Utility Model Content
