Embodiment Construction

[0027] A specific implementation of a straw shredder will be described in detail below in conjunction with the accompanying drawings.

[0028] Such as Figures 1 to 6 As shown, a straw crusher includes a feeding device 9, a discharging device 11, a crushing device 1, and a feeding device 2. The crushing device 1 includes a rotor main shaft 17, a rotor cutter head 12, a flying knife 13, and a knife pin 7. The filter screen 20 and the rotor cutterhead 12 are arranged and fixed on the rotor main shaft 17 with gaps between them. Multiple sets of flying knives 13 are connected to the rotor cutterhead 12 through the knife pin 7. The flying knives 13 are added between adjacent rotor cutterheads 12. The pin sleeve 29 is used to limit the position. Driven by the rotor power unit 10, the rotor cutter head 12 rotates at a high speed, and the flying knife 13 rotates at a high speed with the axis of the rotor main shaft 17 as the center of a circle to generate centrifugal force. The flying...

Abstract

The invention discloses a straw crusher which comprises a charging device, a discharge device, a crushing device and a feeding device, wherein the crushing device comprises a rotor spindle, rotor cutterheads, a plurality of groups of fly cutters, cutter pins and a filter screen; the rotor cutterheads are arranged and fixed on the rotor spindle at equal gaps; the fly cutters are connected with the rotor cutterheads by the cutter pins; gaps are formed between the fly cutters and the filter screen; a discharge port is formed below the filter screen and connected with the discharge device; the feeding device is in an L-shaped structure formed by an upper press roll and a lower press roll and forms a feeding channel; one end, with a larger opening, of the feeding channel faces towards a charging port and is connected with the charging device; the other end of the feeding channel is connected with the crushing device; the lower press roll is formed by arranging feeding rolls in parallel, and is connected with a charging conveying belt; the upper press roller at least consists of a feeding roll, and is mounted on an upper press roller cover; and a hinge is arranged at a charging port end of the press roll cover. The straw crusher has the advantages of simple structure, high crushing efficiency, stability, smaller product particle size and the like.

Description

technical field [0001] The invention relates to the fields of biomass power generation, gasification and papermaking development, in particular to a biomass raw material crusher. Background technique [0002] In biomass power generation, biomass gasification, and papermaking industries, the crushing process of biomass raw materials is complicated and energy-consuming. The efficiency is low, and the foreign matter mixed in the fuel such as stones and iron blocks is easy to impact the rotor and cause equipment damage. The hammer mill crusher has low crushing stability, high energy consumption, and poor crushing effect on flexible biomass raw materials. Contents of the invention [0003] The object of the present invention is to overcome the deficiencies of the prior art and provide a crusher with simple structure, high crushing efficiency, low maintenance cost, and finer particle size of crushed biomass raw material products. [0004] The purpose of the present invention is...
