Abstract

The invention discloses a screw propulsion device of a bulking machine. The screw propulsion device comprises a propulsion screw and a bushing, wherein the propulsion screw is connected with a driving shaft, the bushing is installed on the external circumference of the propulsion screw, and the outer ring of the bushing is fixed in a bulking cavity of a casing. The screw propulsion device is characterized in that the propulsion screw adopts a segmental structure, the thread numbers of the segments are different, and the pitches of the segments are different; and the bushing is multi-segmented, and comprises a smooth bushing with a smooth inner ring and / or a groove bushing, a plurality of grooves are distributed on the internal circumference of the groove bushing, and the multi-segmented bushing is directly sleeved on the external circumference of the propulsion screw. The screw propulsion device has the characteristics of simple structure, good production effect, stable equipment operation, high part durability, wide applicability, high extrusion efficiency and the like.

Description

technical field [0001] The invention relates to a food and feed extruding machine, in particular to a screw propulsion device of the extruding machine. Background technique [0002] With the development of the food industry and feed industry and the improvement of people's living standards, extruders have been widely used in the production of various high-grade food and high-grade livestock and poultry feed. Poultry digestion and absorption, easy storage and other significant advantages, especially for the raw material puffing processing with a starch content of 40%, it is generally required that the raw material after puffing processing is a high-mature product, by adding the high-mature raw material as the main formula component to food or feed , or directly use the highly matured raw material as food or feed, such food or feed is conducive to improving the nutritional content and absorption rate, and improving its taste, especially for young animals, whose physique is rel...
