Is "artificial scorpion nest grid" a patented technology?

The "Artificial Scorpion Nest Grid" is the core device in the "Simulated Natural Scorpion Raising Method", which is divided into two panels, namely, an inner panel and an outer panel. It has the functions of automatically adjusting the humidity of the scorpion pool, raising scorpions in high density, protecting scorpions from being crushed to death, and being easy to manage. The inventor was granted a patent for invention with the patent number ZL003 16983.9.

Size: 60cm× 30cm× 8cm. Manufacturing materials: cement, yellow sand (stone powder). The mixing ratio of cement and yellow sand (stone powder) is 1: 3 ~ 4, and then it is made of a special wooden mold. It is divided into an inner plate and an outer plate. There are two "legs" under the outer plate, which are 8 cm high and lean against the inner plate. The surface of the scorpion board should be rough to facilitate the scorpion to climb, crawl, inhabit and shed its skin through mechanical friction. Scorpion plates can be placed horizontally or vertically. Because the vertical position is too high, pregnant scorpions are prone to miscarriage when they fall, so it is better to put them horizontally if there is plenty of space.
