Extruding type silkworm cooking feed extrusion device and use method thereof

Abstract

The invention relates to an extruding type silkworm cooking feed extrusion device and a use method thereof. The extrusion device comprises a rack provided with a transverse guide rail, a material cylinder glidingly connected to the transverse guide rail, a piston matched with the material cylinder, and a driving device for driving the piston to move to the material cylinder vertically, wherein thematerial cylinder is internally provided with a discharging plate which is transversely arranged and can be replaced; the discharging plate is provided with discharging holes, and the diameters of the discharging holes are different; and the discharging plate with different discharging hole diameters can be replaced according to feeding requirements of young silkworms in different ages. By replacing the discharging plates with different discharging hole diameters, the feed diameters can be adjusted, and the device can be suitable for feeding silkworms at different stages. Through the action of a piston seal ring and a material cylinder slope shape, the excessive feed on corners is pressed out as much as possible, so that the extrusion molding efficiency of the feed is higher; and by virtue of matching among the material cylinder group, a hydraulic cylinder and the piston, the continuous, rapid and efficient silkworm cooking feed extrusion operation is realized.

Description

technical field [0001] The invention relates to the field of silkworm breeding, in particular to the feeding of quantitative cooking feed according to the feeding requirements of different ages of silkworms, and specifically refers to an extrusion type silkworm cooking feed extrusion device and its use method. Background technique [0002] my country is the largest silk producer in the world, and its silk production accounts for more than 80% of the world's total output. Silk export is an important means for my country to earn foreign exchange. Affected by the strategy of moving mulberry from east to west, my country's sericulture industry is mainly concentrated in Guangxi Province. Due to the increase in labor costs, the problem of declining benefits needs to be resolved urgently. Due to the limitation of supply and demand of mulberry leaves, the annual feeding period is only half a year. The use of artificial feed to raise silkworms can make the production of silk industr...

AI Technical Summary

Problems solved by technology

However, currently in my country, we mainly rely on mulberry leaves to feed silkworms, and the steps of leaf picking time, mulberry leaf selection, disinfection and licking, cutting mulberry and feeding mulberry are strict, and the efficiency is low. Therefore, it is urgent to develop a kind of silkworm cooking feed extrusion Device to improve silkworm feeding efficiency
