Description

Mulberry leaf smashing device for silkworm breeding

Technical Field

The invention relates to the technical field of silkworm breeding equipment, in particular to a mulberry leaf crushing device for silkworm breeding.

Background

The mulberry silkworm is also called silkworm. The method is characterized in that the insect is completely metamorphosed, the oligotrophic animal is addicted to mulberry leaves, the growth of the adult silkworm is generally divided into five ages through eggs, larvae (silkworm larvae), pupae and adults (silkworm moths), the larva bodies hatched from the silkworm eggs are small and are called ant silkworms, the old skin can be removed after a certain period of growth along with mulberry feeding, the feeding is stopped before the skin is molted, the adult silkworm is commonly called sleeping, and the adult silkworm enters a new age after the skin is molted once. Silkworm generally sleeps and molts four times, and after five instars, the five instars stop eating to become mature silkworm, and the silkworm spins and cocoons. The mulberry is a perennial woody crop, and at present, four varieties are mainly planted in a large area, including a mulberry, a white mulberry, a wild mulberry and a Guangdong mulberry, which are also called hybrid mulberry and fast-growing mulberry. Raw silk is a product obtained by reeling silkworm cocoons, tussah silkworms, castor silkworms and the like also spin, but the color, the quality and the like of raw silk are not the same as those of mulberry silk, and the raw material generally used for processing silk is the mulberry silk.

The main food of the silkworm is mulberry leaves, particularly in the young silkworm period, the mulberry leaves are required to be clean and anhydrous, meanwhile, because the silkworm baby is too small, the mulberry leaves are required to be crushed and cut into small pieces to feed the silkworm baby, meanwhile, the residual dew and impurities on the mulberry leaves also need to be cleaned, and the silkworm baby can be ill after eating the mulberry leaves, and the growth and health of the silkworm baby are influenced, and even the silkworm baby dies.

However, the processes of removing water and pulverizing mulberry leaves in the silkworm breeding process mostly have the following problems:
