Description

Watermelon seed taking method and device Technical Field The invention relates to the technical field of agriculture, in particular to a watermelon seed taking method and device. Background Watermelon is one of the favorite fruits in summer. The supply of a large quantity of watermelon requires the supply of a large quantity of watermelon seeds. Especially for melon farmers who plant melon seeds as products, in the early stage of melon seed production, the melon seeds are mainly taken out of the pulp by manual means or the pulp is washed out by clear water and then taken out, and no matter what method is, time and labor are wasted. The melon seed extractor comprises a melon breaking mechanism, a frame mechanism and a separating mechanism, wherein the melon breaking mechanism is positioned above the frame mechanism, the separating mechanism is positioned between an upper plate and a bottom plate of the frame mechanism, the melon breaking mechanism comprises a shielding box, a rotating motor, a cutter, a scraping plate and a hydraulic cylinder, the side wall of the shielding box is connected with the rotating motor and the hydraulic cylinder, the cutter is transversely positioned in the shielding box, the cutter is connected with an output shaft of the rotating motor through a bearing, the bottom of the shielding box is connected with the scraping plate, the scraping plate is connected with a movable plug of the hydraulic cylinder, the improvement technology claims that the melon breaking efficiency can be improved, splashing during melon breaking is prevented, personnel are protected, waste is prevented, but the melon seeds are not damaged if the melon peel is further broken after the melon seed is broken, so that the actual application effect of the improvement technology is not good; For example, the existing watermelon seed extractor capable of preventing fruit adhesion in the market comprises a watermelon seed extractor body, wherein the watermelon seed extractor body comprises a stirring tank, one side of the stirring tank is fixedly connected with a feeding pipe, the other side of the stirring tank is fixedly connected with a seed outlet pipe, an electromagnetic valve is arranged in the seed outlet pipe, a liquid outlet is formed in the bottom of the stirring tank, and the bottom of the stirring tank is in a funnel shape. According to the watermelon seed extractor, through the arrangement of the crushing assembly, the servo motor is used for driving the rotating shaft and the crushing blades to cut watermelon pulp, meanwhile, the driving wheel on the crushing rotating shaft drives the driven wheel to rotate, so that the threaded rod rotates, the first through hole on the extruding plate is in threaded connection with the threaded rod, the extruding plate moves up and down, the cut pulp is further extruded, the pulp is changed into juice, and the large-particle watermelon seeds are filtered by the filter screen, so that the watermelon seed extractor is basically far away from the improvement technology and is used for crushing watermelon peel and then taking the seeds, and the problem that the watermelon peel and the melon seeds cannot be separated cleanly at last is not avoided; based on the actual situation, the invention develops a labor-saving and time-saving watermelon seed taking method and a matched device.
