Embodiment Construction
[0011] Embodiments of the present invention are described in further detail below in conjunction with the accompanying drawings:
[0012] Such as figure 1 , figure 2 The biomass fuel scrap cutter shown includes a vertical shaft 4, and the middle part of the vertical shaft is evenly provided with four blades 5 arranged horizontally. The ends of the blades 5 are inclined upward, and the upper surface of one side of the cutter 5 is inclined downward. Gradually thinning transition section 5-1, the thickness b at the end of the transition section 5-1 is 1 / 2 of the thickness a of the blade, i.e. b=a / 2, and the end of the transition section 5-1 is provided with a cutting edge 5- 2. The cutting edge of the cutting edge part 5-2 is at three quarters of the blade thickness a, that is, c=a3 / 4; the upper part of the vertical shaft 4 is evenly provided with four stirring blades 3 protruding outwards in an arc shape, The arc of the stirring blade 3 is an arc of a circle, the cutting edge...

The invention discloses a biomass fuel crushing cutter. The biomass fuel crushing cutter comprises a vertical shaft. Multiple horizontally-arranged blades are evenly arranged in the middle of the vertical shaft. The tail ends of the blades incline upwards. The upper surface of one side of each blade inclines downwards to form a transition section which is gradually thinned. The thickness of the tail end of each transition section is 1 / 2 that of the corresponding blade. Cutting edge parts are arranged at the tail ends of the transition sections. Cutting edges of the cutting edge parts are located at the 3 / 4 thickness positions of the blades. Multiple stirring blades which protrude outwards and are in arc shapes are evenly arranged on the upper portion of the vertical shaft. The arc of each stirring blade is a section of arc of a circle. Cutting edges of the stirring blades are arranged on the tops of the stirring blades. The arc-shaped corner cut of each stirring blade ranges from 24 degrees to 28 degrees. The distances between the upper portions of the stirring blades are larger than those between the bottoms of the stirring blades. The problem that an existing crushing device is incomplete in stirring and not uniform in crushing can be solved.
Description
technical field [0001] The invention relates to the technical field of biomass manufacturing tools, in particular to a scrap cutter for biomass fuel production. Background technique [0002] The device for crushing materials in the production of existing biomass fuels generally includes a cylinder, and the bottom of the cylinder is provided with a crushing knife group. The crushing knife group is generally a plurality of blades arranged horizontally on a vertical shaft. The mouth is located on one side of the blade. Such a biomass fuel scrap cutter, because the stirring of the biomass is not sufficient, will make the biomass near the blade more fully crushed, and the biomass on the upper part of the cylinder is not sufficiently crushed. , part of the crushing device is equipped with a stirring rod inclined upward on the upper part of the vertical shaft. Although the flow of biomass has been improved, it cannot guide the flow direction of biomass and cannot make the flow of b...
