How to carry out the vertical turntable silkworm sericulture?

(1) Advantages: high space utilization rate: The same 20 square meter silkworm house is raised with silkworm cocoons and tripods. It can hold 7~8 silkworm frames and raise 2.3~2.7 large rafts. Breeding with a combination of firewood and bamboo frame can only raise 0.8~1 large silkworms, while raising them with vertical rotary table, can put 5 turntables, can raise 4.6 large silkworms, and the space utilization rate is 1 times and 4 times higher respectively.

Low cost: less investment, less material, and a 7.7% reduction in cost.

Easy to use: 40% of the working hours can be saved by using the vertical rotary table.

(2) Materials and specifications: One of the central axes is made of miscellaneous wooden sticks or fine bamboo, with a length of about 3.4 meters and a diameter of about 8 cm. The support is made of 4 pieces of wood, 94 cm long, and 4 cm wide and thick. There are 14 bamboo pieces, including 10 bamboo leaves on the disc frame, with a circumference of 5.9 meters, a width of 5 cm and a thickness of 0.5 cm. 4 fixed nets of bamboo, about 3 meters long and 5 cm wide. Polyethylene wire braided circular net 10 pieces, diameter 188 cm (radius 90 cm, plus central axis 8 cm), used as a mesh disk. Other materials include wood blocks, wood bricks, bamboo nails, and films.

(3) Production method: make the top of the central shaft into a cylinder with a diameter of about 6 cm, and use a wooden block to make a round hole to cover the cylinder, and fix the wooden block on the roof rafter (such as the upper door shaft of the door panel) . The lower end of the central shaft is slightly pointed and rests on the wooden bricks (the wooden bricks are carved into shallow holes) to enable the shaft to rotate. About 40 cm from the top of the central axis, a cross-shaped blinking, four small wooden crosses fixed as a support. Ten polyethylene wire braided circular mesh discs are inserted from the bottom end of the central shaft. The first net disc is fixed from the lower part 40~50 cm from the ground, and then the distance is 25 cm, which is layer by layer. It is fixed on the central axis and is riveted with bamboo nails. The frame of each net disk is connected with four bamboo pieces vertically and equidistantly. The top of the bamboo piece is fixedly connected with the cross-shaped bracket, so that each net plate is not deformed after being pressed, and does not move. The mesh disk is made with polyethylene wire, take 3 cm net gang, start with 6 meshes, put one eye for each extension, until the weaving extends 25 gangs, which is a round mesh, and the mesh is laid on the ground. Put the bamboo round frame on the net, then tighten the net and tie it tightly along the bamboo frame with a polyethylene thread to form a net. The mesh can be replaced by an old fish net. The mesh disk can also be sewn with a plastic partial woven fabric, and the silkworm can be directly sown on the top, which can save a layer of film and has a lower cost.

(4) Note: 1 Each rotary table of silkworm is generally equipped with 10 nets. If the house is low, the material strength is not enough, and the number of feeding is small, the number of mesh plates can be reduced as appropriate. The maximum weight of silkworm, mulberry and sand can reach about 40 kilograms. All the ligatures must be tight to prevent loose deformation. 3 Use a braided mesh tray to raise silkworms. Because of the large holes, a layer of plastic film or thick paper should be placed on the net. 4 Turntable sand removal should be carried out from top to bottom in order to keep the silkworm body clean. 5 turntable silkworm table can also be used to build up the knots. If you use the "grass dragon" to go up the mountain, you should widen the spacing of the net to 50 cm.
