When the staff needs to crush the material, the top cover is placed on the upper end of the crushing barrel and the handle is turned to make the handle The hand drives the connecting column to rotate through the connecting shaft, and the connecting column fixing block and the positioning block rotate, so that the positioning block with a hexagonal cross section is inserted into the positioning groove of the driving column, and then the top cover is fixed by the quick-release assembly, and the material is poured into the crushing barrel through the feed pipe. Then the driving motor is started, and the output end of the driving motor drives the driving column to rotate. Since the cross section of the positioning block is hexagonal and the cross section of the positioning groove in the driving column is adapted to the cross section of the positioning block, the driving column drives the positioning block to rotate synchronously when it rotates, and the positioning block drives the fixing block and the connecting column to move synchronously, so that the connecting column drives the support plate and the blade to rotate, so that the blade crushes the material. When cleaning is required, the top cover is fixed by the quick-release mechanism, and then the top cover is lifted upward. The top cover drives the connecting shaft and the connecting column to move upward synchronously through the bearing, and the connecting column drives the support plate and the blade to move upward and disengage from the inside of the crushing barrel. At the same time, the positioning block disengages from the positioning groove of the driving column, so that only the driving column remains in the crushing barrel, thereby preventing scratches on the hands when cleaning the powder grinder, with strong safety and improved cleaning effect.

[0005] A handle is provided on the upper surface of the top cover, and the staff can move the handle upwards by hand, which is more convenient and labor-saving.

When cleaning is required, the top cover is fixed by the quick-install mechanism, and then the top cover is lifted upward. The top cover drives the connecting shaft and the connecting column to move upward synchronously through the bearing, and the connecting column drives the support plate and the blade to move upward and out of the crushing barrel. At the same time, the positioning block is out of the positioning groove of the driving column, so that only the driving column remains in the crushing barrel, thereby preventing scratches on hands when cleaning the powder grinder, with strong safety and improved cleaning effect.

[0013] 2. When the utility model is used, the connecting column rotates to drive the cutting edge to rotate synchronously, and the cutting edge and the blade cooperate with each other to improve the material crushing effect.

[0014] 3. When the present invention is used, when it is necessary to install the top cover, the top cover is installed on the upper end of the crushing barrel, and after the positioning block is inserted into the positioning slot of the driving column, the U-shaped limit plate is pulled, and the U-shaped limit plate drives the movable block to move synchronously through the connecting rod, so that the movable block compresses the spring, and then the rotating rod is rotated to rotate around the center of the pin shaft, so that the U-shaped limit plate is sleeved on the upper end of the limit frame, and then the U-shaped limit plate is loosened. The gravity of the U-shaped limit plate itself and the rebound force of the spring can make the U-shaped limit plate tightly pressed against the upper end of the limit frame, thereby fixing the limit frame and the top cover, and the installation process is more convenient.

[0015] 4. When the present invention is used, when the staff installs the top cover, they pull the U-shaped limit plate to the upper end of the limit frame and then release the U-shaped limit plate. The rebound force of the spring causes the card block to be engaged in the card slot, thereby preventing the U-shaped limit plate from positional displacement. When the top cover needs to be removed, the U-shaped limit plate is pulled upward to disengage the card block from the card slot of the limit frame, and then the rotating block is rotated to make the U-shaped limit plate leave the upper end of the limit frame, thereby canceling the limit on the limit frame and the top cover, and then the top cover can be removed. The card block and the card slot of the limit frame cooperate with each other, which can improve the stability of the U-shaped limit plate and the top cover. BRIEF DESCRIPTION OF THE DRAWINGS
