The specific embodiment
Below in conjunction with the drawings and specific embodiments bark grinding mill of the present utility model is described further, to help understanding content of the present utility model.
As depicted in figs. 1 and 2, bark grinding mill, comprise the frame of forming by the upper bracket 2 of base 1 and base 1 upper fixed, a pulverization cylinder 5 cylindraceous is arranged on frame, a cutterhead is installed in the pulverization cylinder 5, place, cutterhead axle center is fixed with power transmission shaft 18, and power transmission shaft 18 is installed on the upper bracket 2 by a power transmission shaft supporting seat 3.A motor 14 is installed on the base 1, a small belt pulley 16 is installed on the output shaft of motor 14, be installed with a big belt pulley 17 on the power transmission shaft 18, driving belt is housed on two belt pulleys 16,17 forms belt transmission, motor 14 drives power transmission shaft 18 by belt gear (or kinds of drive such as chain transmission, gear drive) and drives the cutterhead rotation.The gap that forms between cutterhead edge and the pulverization cylinder inwall is the pulverizing annular space, one circle annular groove is arranged on the cutterhead, many ends fly cutter 8 are inserted in the annular groove on the cutterhead and by hollow pins 10 and are hinged on the cutterhead, stretch out with inswept whole pulverizing annular space to the pulverization cylinder direction when fly cutter is thrown out of under centrifugal action.Have at fly cutter 8 lower positions many bed plate 12 radially to be installed on the frame, and evenly distribute, between fly cutter 8 and the bed plate 12 fit clearance that is no more than 5mm is arranged, generally get 2～5mm according to the characteristics of bark at circumferencial direction; Chamber below upper bracket 2 is located at bed plate 12 has discharging opening 19.When motor 14 drove cutterheads and rotates by belt and power transmission shaft 18, fly cutter 8 rotated around hollow pins 10 cutter head is thrown out of under centrifugal action, cooperated with bed plate 12 bark sheared bark is pulverized.Because fly cutter 8 is to be hinged on the cutterhead, fly cutter 8 meets with it and can oppositely rotate around hollow pins 10 when harder foreign matter such as stone is arranged in the bark, when preventing to shear by force with the impact of buffering foreign matter fly cutter 8 or bed plate 12 bump fractures or knock and collapse.And adopt hollow pins 10 hinged, be convenient to instrument penetrated and in the hole of hollow pins hollow pins taken off, with fly cutter 8 for convenience detach.
It is the structure of rectangle that fly cutter 8 adopts cross sections, utilizes its four rectangular edges to form 4 right angle cutting edges, and its four cutting edges can be used for pulverizing bark.Use a cutting edge to pulverize when fly cutter 8 is just changeing, after this cutting edge is worn, can reverses and use another cutting edge.After two cutting edges on the face all wear and tear, fly cutter 8 can be installed and used the two other cutting edge conversely.Grind a cutter and can use four times, reduce the number of times of sharpening and tool changing, improve the service life of fly cutter.
The cross section of bed plate 12 can be rectangle equally, and 4 right angle cutting edges are arranged, and its four cutting edges can be used for pulverizing bark.Use a cutting edge to pulverize when fly cutter 8 is just changeing, after this cutting edge is worn, can reverses and use another cutting edge.After two cutting edges on the face all wear and tear, bed plate 12 can be installed and used the two other cutting edge conversely.Grind a cutter and can use four times, reduce the number of times of sharpening and tool changing, improve the service life of bed plate.
Pulverization cylinder 5 is installed on above the upper bracket 2, and bed plate 12 is fixed between upper bracket 2 and the pulverization cylinder 5.Above the pulverization cylinder 5 upper shell 6 can be installed, to improve charge, bark is in upper shell 6 falls into pulverization cylinder 5.Upper shell 6 sidewalls have a movable observing door 7, can conveniently be used for examination and maintenance.
Because bark rotates in pulverization cylinder 5 when material is pulverized, more serious to the pulverization cylinder wearing and tearing, for improving the service life of pulverization cylinder, pulverization cylinder 5 inner surfaces are lined with abrasion-proof backing block 9, and abrasion-proof backing block 9 adopts high abrasion resisting material to make.
For ease of discharging, be coaxially connected with a umbrella shape rotating disk 4 in cutterhead lower position one, thereby slide to discharging opening 19 dischargings with the bark after helping pulverizing.Equally, be evenly equipped with the lower coating blade 13 of the projection that multiple tracks radially is provided with, be evenly equipped with the end scraper 15 of the projection that multiple tracks radially is provided with at the lower surface of umbrella shape rotating disk 4 at the upper surface of umbrella shape rotating disk 4.Utilize scraper and action of centrifugal force that the material after the pulverizing is assembled to the discharging opening place.Be evenly equipped with the upper blade 11 of the projection that multiple tracks radially is provided with at the cutterhead upper surface, so that material is scraped to pulverizing annular space.
Usually, fly cutter 8 and bed plate 12 all adopt 4～6 evenly arranging, form 4～6 and shear combination, can reach reasonable crushing effect and increase treating capacity.And upper blade, lower coating blade and end scraper all adopt 4 evenly to arrange, can reach the scraper requirement.
Bark enters in the pulverization cylinder 5 from upper shell 6, and motor 14 drives 16 rotations of motor belt wheel, and the small belt pulley 16 of motor drives power transmission shaft 18 by driving belt and rotates, cutterhead and the rotation of power transmission shaft 18 1 superhigh speeds.The cutterhead of rotation drives fly cutter 8 high-speed motions at a high speed, and fly cutter 8 throws away under centrifugal action, and fly cutter 8 produces shear action and mill stranding effect with the relative moving motion of bed plate 12.The bark that enters in the pulverization cylinder 5 is pulverized under the shearing of the fly cutter 8 of high-speed motion and bed plate 12 and mill are rubbed with the hands, and falls in the cavity of upper bracket 2.Upper blade 11, lower coating blade 13, end scraper 15 produce the effect of breaing up and clashing into fragmentation to bark in high-speed motion simultaneously, play auxiliary pulverization and discharge effect.Bark is driven rotation at a high speed in pulverization cylinder 5 simultaneously, gets rid of from discharging opening 19 under centrifugal action, finishes crushing process.
This pulverizer has that treating capacity is big, efficient is high, energy consumption is low, volume is little, noise is low, makes With advantages such as life-span length.
