Agricultural straw extruding equipment

Abstract

The invention discloses agricultural straw extruding equipment, which comprises an extruding chamber and a chopping mechanism. The chopping mechanism is mounted above one side of the extruding chamber, a feeding hopper is arranged above the chopping mechanism, a chopping tank is arranged below the chopping hopper, a chopping motor is mounted on one side of the chopping tank, and a bevel gear is connected to one side, in the upper portion of the chopping tank, of the chopping motor through a driving shaft. A chopping shaft is mounted at the lower end of the bevel gear, and chopping blades are mounted on the surface of the chopping shaft. Under the action of a propelling rotating shaft, refined materials in the extruding chamber are filtered through a filter plate, and uniformity in materialheating is realized; due to heating wires in a semispherical distribution projection on one side of an extruding plate, material heating area is increased, a current situation that existing straw extruding equipment depends on material friction between the propelling rotating shaft and the inner wall of the extruding chamber to generate heat is changed, and integral energy consumption is reduced.

Description

technical field [0001] The invention relates to the technical field of puffing equipment, in particular to a puffing equipment for agricultural straw. Background technique [0002] Puffing is a processing method. Let the raw material suddenly depressurize under the condition of heating and pressurizing to make it expand. After the starch-containing material is heated and pressurized, the external force and heat source are suddenly removed to make it expand rapidly. The puffing of crop stalks is the process of using feed machinery to convert soybean stalks, corn stalks and other crop straws into food for poultry and livestock through a series of physical and chemical reactions. Under the action of high temperature and high pressure inside the extruder, the crop straws are puffed, In the end, the effect of ripening and puffing the straw can be achieved. The working mechanism is that the corn straw is sent into the extruder through screw extrusion. Under the action of fricti...

AI Technical Summary

Problems solved by technology

[0003] At present, some straw puffing equipment does not have a shredding mechanism. When puffing, the chopped straw is put into the puffing equipment for material ripening. This kind of puffing method has a large workload and low output.

In addition, the existing straw puffing equipment relies on the material friction between the propulsion shaft and the inner wall of the puffing bin to generate heat. This heating method consumes a lot of energy, and the material is heated unevenly in the puffing chamber, which leads to incomplete puffing and affects the quality of the material. Puffed quality
