Description
Technical field
Patent of the present invention is related to a kind of vertical-shaft sand making machine, particularly a kind of multistage bar sand making machine of vertical shaft type.
Background technology
Natural sand stone is the non-renewable resources in short-term, with the high speed development of China's capital construction, natural sand stone
It is closely exhausted.Simultaneously as the catastrophic collapse that excavation sandstone is caused to resource and environment, for flood control, environmental protection, protection of resources
Etc. all many factors, many cities have prohibitted the use of natural sand.Vertical-shaft sand making machine is exactly a kind of building materials system of developed recently
Sand equipment, the building stones such as rock, ore or natural cobblestone can be crushed and industrial sand is made by it, to replace natural sand.It is existing
Vertical-spindle hammer crusher more use individual layer or two-layer rotor structure, material falls from upper end charging aperture into crushing cabin to from discharging opening
During, the number of times that the impact being subject to casts and mutually collided is few, and the raw meal particle size after crushing is big, and Vibration Screen is passed through in discharging
After point, the rubble overproof to particle diameter is crushed again.Energy consumption of unit product is high, efficiency is low, second-time breakage amount account for 50% with
On.Therefore, those skilled in the art achieve certain progress through great efforts.Such as China Patent Publication No. CN104226421A,
December 24 2014 publication date, invention and created name " three layers of impeller breaker ".It the patent application disclose a kind of available
In the disintegrating machine of sand processed, it is by setting three layers of hardened structure of hammer, and increase impact casts the probability and number of times of material, and corresponding increase is touched
Number of times is hit, so as to effectively improve sand efficiency processed, sand energy consumption processed is reduced.But the equipment still eliminates lacking for generally existing in existing equipment
Fall into, i.e. the impact surface of bar crosses rotor axis.Because bar persistently rotates in the course of the work, bar impact surface near-end is reflected
Material, in ejection process easily by same bar impact surface distal end touch, it is this touching the overwhelming majority formed friction damage
Consumption, spent material kinetic energy, reduction and the mutual collision energy between barrel upper guard board or material, influence into sand coarse aggregate ratio.For this reason, it may be necessary to
Further improve.
The content of the invention
The present invention seeks to there is provided a kind of multistage bar sand making machine of vertical shaft type, it is right that it passes through in view of the shortcomings of the prior art
The improvement of board hammer structure, effectively increases the energy utilization rate of sand making machine and into sand coarse aggregate ratio.
To achieve the above object, the present invention is adopted the following technical scheme that.
A kind of multistage bar sand making machine of vertical shaft type, including main body are located at the bar rotor in crushing cabin, and bar rotor stretches out
The part of the crushing cabin bilge is connected by belt transmission component with motor, and bar rotor is hammered into shape by rotor block and multiple strips
Plate, arrangement form of the hammer plate by length perpendicular to rotor body axis is fixedly connected on rotor block, and multiple plates of hammering into shape are along rotor block axle
Line is distributed to form multilayer board hammer structure, tripper is provided with the charging aperture above bar rotor, the bilge of crushing cabin is provided with discharging
Hammer plate in bucket, any layer is provided with two of circumference uniform distribution, and the hammer plate of adjacent layer misplaces 90 ° in a circumferential direction, and hammer plate is by near
End to distal end is tilted backwards relative to direction of rotation.
Computer simulation according to scientific research institution to reaction pulverizer crushing material process, material it is broken more than 60%
It is mutually collision rift acquisition between material.Using the multistage bar rotor of preceding solution, plate quantity is hammered into shape in individual layer bar
Two of circumference uniform distribution are only set to, adjacent layer hammer plate misplaces 90 ° in a circumferential direction, compared with individual layer three and above hammer plate
Speech, its material crash space is improved significantly, collision probability and number of times after increase strike projectile；Meanwhile, on rotor
Hammer plate is scattered in sandwich construction, and material is in dropping process from top to bottom, with the chance for repeatedly being impacted and being cast by bar,
So as to the collision after repeatedly being accelerated with crushing the backplate collision of cabin bulkhead and repeatedly being formed between material；Importantly,
In this programme, hammer plate is tilted backwards by near-end to distal end relative to direction of rotation；The thing from hammer plate near-end refraction can effectively be reduced
Material is eliminated or reduced because touching and rub and the energy in-fighting that produces by the touching of hammer plate distal end, friction, improve energy utilization rate with
Percentage of damage, it is corresponding to obtain preferably into sand coarse aggregate ratio.Meanwhile, according to aerodynamic principle, by near-end to distal end relative to rotation side
To sweptback hammer plate, the wind-force pushed to bulkhead can be also formed in work rotation, further increase material is thrown from hammer plate
The energy of injection, it is to avoid axle center be formed about material be vortexed and material energy and equipment dynamic is lost so that improve percentage of damage and
Ensure energy utilization rate.
It is preferred that, the rotor is by hammering plate shape into shape at least two-stage bar area, and the hammer plate in any level bar area is provided with extremely
