technical field

The invention relates to a watermelon seed harvesting device of a straight plate loosening straight paddle screw rubbing extrusion differential circulation stirring type.

Background technique

Watermelon seeds, also known as watermelon seeds, are the seeds of Cucurbitaceae watermelon, which can be used for food or medicine. Generally speaking, the seeds in the watermelon we eat every day can also be made into watermelon seeds, but the size is too small, so the watermelon seeds produced on the market usually come from special watermelon varieties. Watermelon seeds are rich in protein, fat, vitamin B, Nutrients such as D are mostly used for daily consumption, and they are generally delicious foods that people like.

With the development of agricultural science and technology, new watermelon varieties with the main purpose of producing watermelon seeds have been selected and bred. Watermelon seeds mainly exist in the flesh inside the watermelon. Seeding watermelon is a necessary step to realize watermelon seed processing. Whether it is made into a dry product or the subsequent intensive processing requires the watermelon to be seeded. However, at this stage, almost all watermelon seeds are harvested manually, which is not only low in efficiency, heavy in workload, but also high in cost, which is not conducive to the development of the watermelon seed industry.

Connect the magnetic differential stirring pump, the magnetic differential stirring pump is connected in parallel with the bottom pipe of the water washing tank through the control valve and the branch pipe, the water washing tank is a cone bottom structure, and the bottom pipe is provided with a bottom valve; the magnetic differential stirring pump includes a drive shaft, The active magnetic cylinder and the passive magnetic cylinder, the active magnetic cylinder and the passive magnetic cylinder are set and the magnetic poles are arranged symmetrically one by one according to the center, such as a large round wooden barrel with a small round wooden barrel and the number of magnetic strips is equal to that of a wooden barrel. Accurate one-to-one correspondence between the north and south poles, all arranged symmetrically in the center, and then packaged into a solid body, the driving shaft is connected to the active magnetic cylinder, and the passive magnetic cylinder is connected to the impeller of the mixing chamber and sealed with a flange connection. The mixing chamber is equipped with a liquid inlet and the liquid outlet; there is a stainless steel isolation cover between the active magnetic cylinder and the passive magnetic cylinder for sealing and isolation, but the magnetic force can pass through the stainless steel isolation cover to realize the magnetic transmission of the two magnetic cylinders. There are central shafts, bearings and clamps on the stainless steel isolation cover The ring is used to fix and flexibly rotate the moving parts.

The feeding end of the loosening drum is connected with a vibrating feeder.

The pulp slurry flow tank is connected with the pulp slurry temporary storage tank.

Mature watermelons for seed production are put into the vibrating feeder, and vibratingly conveyed into the feeding end of the loosening drum. A copying board is arranged in the drum. When the drum rotates, the materials in it are continuously rolled, lifted, and Rolling and squeezing each other can loosen the melon pulp and melon skin, melon pulp and melon seeds, and enter the differential speed roller with the rotation of the material.

The loosened watermelon falls into the differential speed roller from the lower end. The differential speed roller has convex strips to facilitate the biting of the balls, and the distance between the rollers and the relative differential speed can be adjusted to rotate, which is especially beneficial to the skin and flesh of the melon. separation without damaging the seeds.

Although the transmitted torque, speed, and power are all reduced at this time, the up and down movement of the active sine wave toothed disc will cause the two toothed discs to slip and differential. For example, through frequency conversion speed regulation and load The adjustment makes the two toothed discs repeatedly engage, differential, separate, and engage, and then produce differential transmission and torque pulsation, so that the mechanical energy output by the drive shaft has the characteristics of differential, pulsation, and vibration, and due to the sine wave characteristics of the tooth surface , the smooth transition performance is particularly good when the two toothed discs are repeatedly engaged and slipped differentially

When the coarse sorting drum sieve and the pulp-separating rubbing drum sieve rotate, a little point brake operation similar to that of a car will cause the sine wave gear disc to differentially generate sliding and pulses, which is especially beneficial for materials to pass through the sieve holes under working conditions. The sieve efficiency is particularly high.

The core of the magnetic differential stirring pump is the set of active magnetic cylinder and passive magnetic cylinder. When the output torque does not exceed the maximum torque that the two magnetic cylinders can carry, the magnetic poles arranged by the two magnetic cylinders can correspond to each other, realizing Synchronous rotation, but when the load exceeds the maximum torque that the two magnetic cylinders can carry, such as through frequency conversion speed regulation and valve flow adjustment, the two magnetic cylinders will have differential motion, which plays a protective role similar to clutch slipping. At this time, although the transmission Torque, speed, and power are all reduced, but the alignment and misalignment of the differential magnetic poles of the magnetic cylinder will repeatedly change into alternating attraction and repulsion, and then magnetic pulsation can be generated, so that the output fluid has the characteristics of pulsation and vibration, and Changing the dynamic seal of the transmission shaft into a reliable static seal also has the function of completely eliminating the leakage of the transmission shaft.

The melon seeds are stirred and washed in the water washing tank. When the valve is opened and the flow rate of the magnetic differential stirring pump is large and the load is heavy, the magnetic drive will generate a differential motion, so that the output flow has a pulse characteristic, which is especially beneficial for the thorough cleaning of the melon seeds. The melon seeds are exported in good time for use.
