straw feeder

Abstract

The invention discloses a novel straw feeding machine which comprises a machine shell, a feeding main shaft, drive motors, couplers and bearing blocks. The feeding main shaft comprises impeller shafts and shaft heads located at the two ends of each impeller shaft. The inner sides of the shaft heads and the impeller shafts are connected through flanges. The outer sides of the shaft heads are installed on the bearing blocks. Each impeller shaft comprises a center shaft cylinder and a plurality of blades which are installed on the outer circumferential face of the center shaft cylinder, wherein the blades are divided into multiple sections on the outer circumference of the center shaft cylinder, each section includes the corresponding multiple blades which are evenly distributed on the arc face of the outer circumference of the center shaft cylinder, every two adjacent sections of blades are distributed in a staggered manner, the blades are divided into the four sections on the outer circumference of the center shaft cylinder, the corresponding eight blades are arranged on each section and are evenly distributed on the arc face of the outer circumference of the center shaft cylinder in a radial shape, the included angle between every two adjacent blades on the same section is 45 degrees, and every two adjacent sections of blades are distributed in the staggered manner with the included angle being 11.25 degrees. The novel straw feeding machine has the beneficial effects of being even in material distributing, simple in structure and convenient to maintain and replace.

Description

technical field [0001] The invention relates to the technical field of under-silo feeding equipment, in particular to a straw feeder. Background technique [0002] The straw feeder is a kind of under-bin feeding equipment specially developed for the characteristics of biomass fuel in biomass power plants. It is mainly used for uniform and continuous unloading in biomass fuel mechanization and automatic control systems. Due to the light and soft texture of biomass fuel, the lack of fluidity, the phenomenon of material entanglement is serious, and the cutting process is difficult to ensure the ideal length, the phenomenon of bridging and arching is often encountered in the process of biomass feeding, especially for soft straw materials , Bridging and arching are very common in all feeding links, resulting in uneven cloth on the conveyor belt, which affects the normal operation of the belt conveyor and belt conveyor auxiliary equipment (such as electronic belt scales, etc.).
