Description

Technical Field

[0001] This utility model relates to the field of grinding device technology, and in particular to a grinding device for producing lotus seed products. Background Art

[0002] Lotus seed, a traditional Chinese medicine, is the dried, mature seed of the lotus plant (Nelumbo nucifera), belonging to the Nymphaeaceae family. It is distributed throughout China, both in the north and south. It has the effects of tonifying the spleen and stopping diarrhea, stopping leukorrhea, benefiting the kidneys and astringing essence, and nourishing the heart and calming the mind.

[0003] Currently used equipment for grinding lotus seeds into powder uses grinding discs. Because the gap between the grinding discs is fixed, the particle size is fixed, which cannot meet the needs of lotus seed powder of different specifications. Utility Model Content

[0004] In view of the shortcomings of the prior art, this utility model provides a grinding device for lotus seed product production, which overcomes the shortcomings of the prior art and effectively solves the problem that the fixed gap between the grinding discs in the prior art results in a fixed particle size, which cannot meet the needs of lotus seed powder of different specifications.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A grinding device for producing lotus seed products includes a fixed shell. An upper grinding disc is connected to the top of the fixed shell, and a feed hopper is inserted and fixed to one side of the top of the upper grinding disc. A rotating rod is rotatably connected to the top center of the upper grinding disc, and a hexagonal column is fixed to the bottom of the rotating rod. A lower grinding disc is inserted into the hexagonal column, and a connecting rod is fixed to the bottom of the lower grinding disc. A support plate is rotatably connected to the connecting rod, and a guide rod and a screw are respectively connected to the bottom two ends of the support plate. Both the guide rod and the screw are connected to a fixing frame, and the fixing frame is fixed to the bottom of the annular inner wall of the fixed shell.

[0007] Lotus seeds are fed into the hopper and fall between the upper and lower grinding discs. The first servo motor drives a rotating rod through meshing gears, which in turn drives the lower grinding disc through a hexagonal prism, grinding the lotus seeds between the upper and lower grinding discs. After being ground into powder, the powder falls down the lower grinding disc into a collection box placed below. The second servo motor drives a screw through meshing gears, which moves spirally along the fixed frame. The screw, in conjunction with a guide rod, moves along the fixed frame to adjust the distance between the support plate and the fixed frame, thus adjusting the distance between the lower and upper grinding discs to achieve different degrees of grinding.

[0008] Preferably, both sides of the annular outer wall of the fixed shell are fixed with support frames, and the top of the fixed shell is provided with positioning grooves distributed at equal intervals along the annular shape.

[0009] The fixed shell is lifted by the support frame, making it easier to place the collection box below the fixed shell.

[0010] Preferably, the annular outer wall of the upper grinding disc is fixed with equidistantly distributed positioning blocks, and the positioning blocks and positioning grooves form an interlocking fit.

[0011] The upper grinding disc is fixed to the top of the fixed shell by a positioning block.

[0012] Preferably, a first servo motor is installed on the top of the upper grinding disc, and the output shaft of the first servo motor and the top of the rod wall of the rotating rod are both fitted with meshing gears.

[0013] The first servo motor drives the rotating rod to rotate through meshing gears.

[0014] Preferably, the bottom of the upper grinding disc and the top of the lower grinding disc are both fitted conical structures, and the top of the lower grinding disc is provided with a hexagonal groove that is fitted with a hexagonal prism.

[0015] The grinding operation is achieved by connecting hexagonal prisms to hexagonal slots, which in turn drive the lower grinding disc to rotate.

[0016] Preferably, a fixing plate is fixed to the bottom of the guide rod, and a second servo motor is installed on the top of the fixing plate. The output shaft of the second servo motor and the bottom end of the screw are both fitted with meshing gears. The guide rod is fixed to the bottom of the support plate and movably inserted into the fixing frame. The screw is rotatably connected to the bottom plate of the support plate and screwed to the fixing frame.

[0017] The second servo motor drives the screw to rotate through meshing gears. The rotating screw moves spirally along the fixed frame and moves in conjunction with the guide rod along the fixed frame to adjust the distance between the support plate and the fixed frame, thus adjusting the distance between the lower grinding plate and the upper grinding plate, enabling grinding of different degrees.

[0018] The beneficial effects of the utility model are:

[0019] The rotating rod drives the lower grinding disc to rotate via a hexagonal column, grinding the lotus seeds between the upper and lower grinding discs. After the lotus seeds are ground into powder, they fall along the lower grinding disc into a collection box placed below for collection. The rotating screw moves spirally along the fixed frame, and the guide rod moves along the fixed frame to adjust the distance between the support plate and the fixed frame, thus adjusting the distance between the lower and upper grinding discs. This allows for different degrees of grinding and effectively solves the problem in existing technologies where the fixed gap between the grinding discs results in a fixed particle size, which cannot meet the needs of lotus seed powder of different specifications.
