Melon crop pulp breaking and seed taking separation device Technical Field The invention relates to a seed taking device, in particular to a melon crop pulp crushing and seed taking separation device. Background Watermelon seeds are used as important agricultural product raw materials, and the seed extraction process directly influences the subsequent processing quality and economic benefit. At present, watermelon seed extraction mainly comprises two modes of manual seed extraction and mechanical seed extraction. After manual seed taking is carried out, the seeds are separated by manual rubbing, panning and other modes, and the mode has high labor intensity and low production efficiency and is difficult to adapt to the large-scale processing requirement. In order to solve the problem of low efficiency of manual seed extraction, some mechanical seed extraction devices are appeared on the market, and the watermelon pulp is crushed by adopting a crushing and stirring principle, and then the seeds are separated by a filtering mode. However, the existing mechanical seed extraction device has the following defects in practical application: Firstly, most of the equipment adopts a blade rotating at a high speed to crush the watermelons, and mechanical damage is easily caused to watermelon seeds in the crushing process, so that the seeds are broken and the surface is scratched, and the commodity value and the germination rate of the watermelon seeds are affected. Secondly, the crushing and separating procedures of the existing equipment are mostly continuous operation, the pulp and the seeds are not thoroughly separated, part of pulp residues are easy to adhere to the surfaces of the seeds, and the subsequent cleaning difficulty is increased. As in patent 202120847353.0, a watermelon seed extractor capable of preventing fruit adhesion is disclosed. The crushing blade is used for crushing the pulp, and the extrusion assembly is used for extruding the pulp of the watermelon to further refine the pulp, but the pulp is only crushed sequentially, and the pulp and the melon seeds cannot be separated effectively. Aiming at the problems, partial improvement equipment tries to optimize the seed taking effect by adjusting the crushing force or adding the filtering device, but is still difficult to ensure the seed taking efficiency and simultaneously consider the integrity of the seeds and the pulp separation effect. Therefore, how to design a watermelon seed taking device which can not only take seeds efficiently, but also protect the complete seeds and prevent pulp from adhering becomes a technical problem to be solved in the field. Disclosure of Invention The invention provides a melon crop pulp crushing and seed taking separation device, which aims to overcome the defects in the prior art, the pulp crushing part can flexibly extrude the melon pulp, the melon pulp and the melon seeds can be separated efficiently, and the melon seed epidermis can not be damaged.
