Description

Silkworm rearing bed and labor-saving silkworm rearing device

Technical Field

The utility model belongs to the technical field of sericulture equipment, more specifically says, the utility model relates to a silkworm rearing seat and laborsaving sericulture device.

Background

In the process of silkworm breeding, the silkworm excrement removed from the silkworm rearing bed and the silkworm breeding net and the residual impurities such as mulberry leaves and mulberry stalks are collectively called as the sand removal. A silkworm breeding and sand removing operation is to breed silkworms in a silkworm rearing bed, when the silkworm rearing bed needs to be subjected to sand removal, a silkworm net with mulberry leaves laid thereon is placed on the silkworm rearing bed, after the silkworms climb up, the silkworm net is lifted and removed, the silkworm rearing bed is cleaned, and finally the silkworms are placed back into the silkworm rearing bed for breeding. Although the mode can clean the growth environment of the silkworm, the accumulated silkworm excrement in the silkworm seat can be more and faster because the silkworm seat does not have a channel for discharging outwards in real time, so that the cleaning frequency is high, and the labor capacity is large. To this end, another kind of silkworm breeding and sand removing operation is to breed silkworms on the silkworm breeding net, and the silkworm breeding net below is placed the base and is collected the silkworm excrement that drops, and the silkworm breeding net has the passageway of discharging the silkworm excrement to the base in real time, reduces the silkworm excrement and reduces the clearance frequency on the silkworm breeding net, is favorable to keeping the clean of culture environment. When the silkworm breeding net and the base need to be cleaned, the second layer of silkworm breeding net paved with mulberry leaves is added on the first layer of silkworm breeding net of the base, after silkworms climb to the second layer of silkworm breeding net, the second layer of silkworm breeding net is lifted, the first layer of silkworm breeding net below is taken out of the cleaning and cleaning base, and then the second layer of silkworm breeding net is put on the base to be continuously cultured.

Because prior art's silkworm net or sericulture net are used for shifting the silkworm and discharging the silkworm excrement, the adoption be conventional otter board realize, the mesh is greater than or slightly be greater than the silkworm excrement can, and the thickness to the otter board among the prior art is not in the scope of consideration of breeding technique, only the otter board has enough support can, for example there is the silkworm to climb to the silkworm net or sericulture net back often and eat and drop from the back of net in the plastics sericulture net of conventional wire net or qiao yuan production, often need the manual work to pick up the silkworm, both cause the amount of labour big, cause the harm to the silkworm that drops again. And the iron wires of the latticed silkworm raising net are criss-cross, so that the net is not easy to clean and the labor capacity is increased.
