Horizontal-grate barrier-free matured silkworm mounting device

The invention discloses a horizontal-grate barrier-free matured silkworm mounting device. Multiple layers of planes are arranged in a frame to form two sets of parallel wood chip horizontal grates; the length of each wood chip of the wood chip horizontal grates is determined according to the length of the inner edge of the frame; the width of each wood chip is 20-30 mm; the thickness of each wood chip is 2-8 mm; the inner spacing H between the planes of the two wood chips of the horizontal grates is 25-30 mm; and the planes of the two sets of wood chip horizontal grates are of a staggered structure with a staggered interval G of 3-10 mm. The horizontal-grate barrier-free matured silkworm mounting device has the advantages of durability, low cost, high cocoon harvesting speed, low labor and time consumption, easiness in disinfection treatment and the like.
