Description

Technical Field

[0001] This utility model relates to the field of cement production, and in particular to a cement crushing and unblocking device. Background Technology

[0002] A search of Chinese patents revealed an announcement number: CN212268388U, which describes a cement silo bottom unblocking machine. The machine includes a discharge channel connecting to the bottom of the cement silo, a mixing chamber, a mixing device, and a shovel rod. The mixing chamber is located below the discharge channel and is connected to a discharge pipe. The mixing device is located within the mixing chamber and includes a rotatable mixing shaft and a crushing blade mounted on the shaft. The upper part of the shovel rod is movably located within the mixing chamber, and when the rod moves upward, its upper end can extend into the discharge channel. This invention's mixing device within the mixing chamber can crush cement blocks during cement silo discharge. When cement blocks block the discharge channel, the shovel rod can clear the blockage, improving the smoothness of cement transportation, increasing cement transport efficiency, and effectively preventing valves from being blocked by large pieces of material.

[0003] Existing crushing and unblocking devices are not convenient for adjusting the discharge direction. Generally, the discharge direction of crushing and unblocking devices is vertically downward. If the discharge direction needs to be changed, a bend needs to be installed. However, the bend is fixed with bolts. Once installed, if the discharge direction needs to be changed, the bend needs to be disassembled, adjusted, and then reinstalled. The adjustment is relatively troublesome, increases the workload, reduces practicality, and is also inconvenient to install and disassemble. Generally, crushing and unblocking devices are installed and fixed to the cement silo discharge port with multiple bolts. When installing and disassembling them, tools are required, which is also troublesome, increases the workload, and reduces work efficiency. In order to solve the above problems, we propose a cement crushing and unblocking device. Utility Model Content
