Description

Technical Field

[0001] The utility model relates to the technical field of cylinder dust prevention, in particular to a cylinder dust prevention device used in a lotus seed core removing machine. Background Art

[0002] Lotus seeds are the dried mature seeds of the lotus plant of the Nymphaeaceae family. They are widely distributed in provinces in northern and southern China. Because they have the effects of tonifying the spleen and stopping diarrhea, stopping leukorrhea, benefiting the kidneys and astringing semen, nourishing the heart and calming the mind, they are often used to treat spleen deficiency diarrhea, leukorrhea, spermatorrhea, palpitations and insomnia. However, the lotus seed core is bitter, and the lotus seed core usually needs to be removed before eating or using it for medicinal purposes. The traditional core removal method mostly relies on manual labor, which is not only inefficient, but also may damage the lotus seed kernel and cause losses. Therefore, in order to meet the requirements of large-scale production, mechanized lotus seed core removal machines have been widely studied and applied.

[0003] Lotus seed core removal machines are generally driven by a cylinder to extend and retract a hollow needle into the lotus seed to remove the lotus seed core. During production, it was found that when the cylinder drives the hollow needle to remove the core, the needle pierces the lotus seed. Since the lotus seed core contains a natural mucus lubricant, the needle pierces the lotus seed and causes the lotus seed to spray mucus. The sprayed mucus splashes onto the periphery of the piston rod. When the piston rod moves, the mucus is brought into the cylinder, affecting the service life of the cylinder. Therefore, a cylinder dustproof device is needed to prevent the mucus from spraying into the piston rod and the cylinder. Most existing cylinder dustproof devices have complex structures, cumbersome disassembly and installation steps, high production costs, and low practicality. Utility Model Content
