Description

Technical Field

[0001] The invention relates to the technical field of melon seed processing, in particular to a melon seed high-efficiency impurity removal and screening device. Background Art

[0002] Watermelon seeds are the seeds of the watermelon plant of the Cucurbitaceae family. They can be eaten or used for medicinal purposes. Generally speaking, the seeds in the watermelons we eat daily can also be made into watermelon seeds. The seeds of specially grown watermelons are taken from them. Only the larger seeds are worth processing and utilization. After proper processing, they can be made into very popular small foods and snacks. When collecting the melon seeds in the melon pulp, the melon seeds need to be cleaned and the deflated shells, incomplete defective products, dust or stones and other debris mixed in the melon seeds need to be screened out.

[0003] Most of the existing melon seed high-efficiency impurity removal and screening devices use a vibration motor to vibrate the melon seeds, and use the different densities of melon seeds and impurities to remove impurities from the melon seeds under the action of gravity. However, when the amount of melon seeds to be processed is large, the melon seeds on the upper layer cannot fully contact the screen, and impurities with a density lower than that of melon seeds, such as paper scraps and floating dust, cannot be effectively removed. Summary of the invention

[0004] The purpose of this section is to summarize some aspects of the embodiments of the present invention and briefly introduce some preferred embodiments. Some simplifications or omissions may be made in this section and the specification abstract and the invention title of this application to avoid blurring the purpose of this section, the specification abstract and the invention title, and such simplifications or omissions cannot be used to limit the scope of the present invention.

[0005] In view of the above problems and / or the problems existing in the existing melon seed efficient impurity removal and screening devices, the present invention is proposed.

[0006] Therefore, the purpose of the present invention is to provide a watermelon seed efficient impurity removal and screening device. During use, watermelon seeds and water are poured into the water storage tank from the first feeding port, and the small particle screening component is driven by the driving component to screen the impurities and empty watermelon seeds with a density smaller than that of the watermelon seeds. Since the density of the watermelon seeds is smaller than that of water, they will sink to the bottom of the water, and the impurities and empty watermelon seeds with a density smaller than that of water and watermelon seeds will float on the water surface. The small particle screening component screens out the impurities and empty watermelon seeds with a density smaller than that of the watermelon seeds, and at the same time drives the cleaning component to clean and collect them, and at the same time drives the taking out component to clean and collect them. The material component takes part of the watermelon seeds in the water storage tank to the first material bin, and the driving component drives the first pulley to rotate, and drives the sealing block to reciprocate laterally along the inner wall of one end of the air pipe with the cooperation of the first connecting rod and the second connecting rod, so that a unidirectional airflow is generated at the air outlet, and the watermelon seeds come into contact with the airflow when falling through the first outlet. Under the action of gravity, impurities with a density greater than that of watermelon seeds fall into the second material bin closer to the air outlet, and the watermelon seeds fall into the third material bin farther from the air outlet for screening. At the same time, the wet watermelon seeds are air-dried, which improves the impurity removal effect to a certain extent.
