Description

Technical Field

[0001] The utility model relates to the technical field of stirring paddles, in particular to a stirring paddle with adjustable blade height. Background Art

[0002] The stirring paddle with adjustable blade height is a specially designed stirring device, usually used to stir, mix or agitate solid particles in liquids. This stirring paddle has the function of adjusting the blade height, which allows users to adjust the position and angle of the blade as needed to achieve different stirring effects and operating requirements.

[0003] After searching, the announcement number CN219942435U is a stirring paddle with adjustable blade height, including: a main shaft, a secondary shaft, a first blade and a second blade; the secondary shaft is coaxially connected to the output shaft of the motor and the main shaft, and the bottom end of the secondary shaft is higher than the stirring liquid level; the first blade is fixedly installed at the bottom end of the main shaft, and the main shaft and the first blade are an integral part; the main shaft is provided with a plurality of mounting parts along its axis, and the second blade includes a first blade and a second blade, and the first blade and the second blade are detachably connected to any mounting part. The bottom end of the secondary shaft is higher than the stirring liquid level, so there is no need to worry about the material entering the gap between the main shaft and the secondary shaft. The second blade can be completely removed from the main shaft, and the staff can clean the main shaft, the first blade and the second blade separately, and then install the second blade on the main shaft. Since there is no cleaning dead angle, the material will not accumulate in the gap between the main shaft and the second blade.

[0004] Based on the above patent, the bottom end of the secondary shaft is higher than the stirring liquid level, so there is no need to worry about the material entering the gap between the main shaft and the secondary shaft.
