Description
Technical field
The present invention relates to a kind of low noise branch crushing machine, belong to field of mechanical technique.
Background technology
Along with the development that Re-search on Urbanization is built, the green coverage in each cities and towns constantly increases.Annual typhoon season is arrived before and is all needed that trees are pruned to control tree-like, a large amount of branch autumn and pruned.China has forbidden burning branch stalk etc. in most cities at present, and the materials such as branch stalk are adopted compost, wood chip are gasificated into fuel gas or make wood and mould the processing modes such as environment-friendly materials.But the basic premise of all these branch processing methods is all that branch is pulverized, although domestic many producers have all released the branch crushing machine of different model to market at present, operating efficiency is also higher, but in the course of work, noise is very large, the one, will affect staff's health, in addition, generally operation on urban road when gardens department pollard, in order to reduce transport and carrying cost, need carry out scene to the branch of pruning pulverizes, in order to bring noise pollution to resident on the way, require noise not higher than 80 dB, therefore design a kind of low noise branch crushing machine very necessary.
Summary of the invention
For addressing the above problem, object of the present invention, just in order to solve above-mentioned the deficiencies in the prior art, provides a kind of low noise branch crushing machine very easily.
For addressing the above problem, the present invention is achieved by the following technical solutions:
A kind of low noise branch crushing machine, by prime mover 1, shaft coupling 2, decelerator 3, key 1, gear 5, taper roll bearing 6, lower cutter shaft 7, disc type cutter 8, support cutter annulus 9, locking nut 1, lower block 11, right end cap 12, middle housing 13, upper cutter shaft 14, upper box lid 15, right left end cap 16, locking nut 2 17, key 2 18, feed hopper 19, stay bolt 20, key 3 21, discharge bucket 22 etc. and form.It is characterized in that: lower block 11 is arranged on pedestal by bolt, the rolling bearing 6 at lower cutter shaft 7 two ends is arranged on the bearing saddle bore of lower block 11, middle housing 13 is arranged on lower block 11 by alignment pin, the rolling bearing 3 at upper cutter shaft 14 two ends is arranged on the bearing saddle bore of middle housing 13, and upper box lid 15 is arranged on middle housing 13 by alignment pin; Lower block 11, middle housing 13 and upper box lid 15 are tightened together by 4 other stay bolts 20 of bearing saddle bore.Middle housing 13 ends, front and back have charging aperture and discharging opening, and feed hopper 19 is installed to by bolt on the charging aperture position of middle housing 13, and discharge bucket 22 is installed on the discharging opening position of middle housing 13 by bolt.Upper and lower two cutter shafts are designed to hollow-core construction, on periphery, be designed to as requested two keyways or spline structure, interval, middle part is provided with the disc type cutter 8 of equal number and supports cutter annulus 9, disc type cutter 8 is with identical to cutter annulus 9 axial widths, on endoporus, have keyway, on disc type cutter 8, be evenly equipped with some and the cutter cutter tooth with width, blade has the helical angle of 25 °～45 °, and two ends adopt respectively the shaft shoulder and locking nut 10 axial restraints; It is 1 gear 5 engaged transmission that a pair of speed ratio is installed in the end that 6, two cutter shafts of rolling bearing are installed at the axle journal place of axle, and gear is by key 18 transferring power on upper and lower cutter shaft.When assembling, the cutter tooth 8 of upper cutter shaft 14 embeds in the cutter tooth teeth groove of lower cutter shaft 7, and ensure that the cutter tooth top of upper and lower cutter shaft 7 and the gap of supporting between cutter annulus 9 on another axle are not more than 0.5mm, the end face axial gap of adjacent two the disc type cutters 8 of cutter shaft is not more than 0.1mm up and down.Drive system inputs to decelerator 3 by shaft coupling 2 power by prime mover 1, and the power output shaft of decelerator 3 extend in the endoporus of lower cutter shaft 7 or upper cutter shaft 14 according to actual conditions, or upper and lower cutter shaft input power simultaneously; The bore design of lower cutter shaft becomes corresponding keyway or spline structure, and by key 4 transferring power.
The invention has the beneficial effects as follows: a kind of branch crushing machine, simple in structure, noise is low, with low cost, safe and reliable.
Brief description of the drawings
Fig. 1 is a kind of low noise branch crushing machine of the present invention front view, and Fig. 2 is this branch crushing machine left view.
Detailed description of the invention
As depicted in figs. 1 and 2, a kind of low noise branch crushing machine, by prime mover 1, shaft coupling 2, decelerator 3, key 1, gear 5, taper roll bearing 6, lower cutter shaft 7, disc type cutter 8, support cutter annulus 9, locking nut 1, lower block 11, right end cap 12, middle housing 13, upper cutter shaft 14, upper box lid 15, right left end cap 16, locking nut 2 17, key 2 18, feed hopper 19, stay bolt 20, key 3 21, discharge bucket 22 etc. and form.Control rotating speed and the rotation direction of prime mover by electrical control gear or fluid pressure drive device, when pulverizer comminution process, prime mover 1 inputs to decelerator 3 power by shaft coupling 2, the power output shaft of decelerator 3 extend in the endoporus of lower cutter shaft 7 or upper cutter shaft 14 according to actual conditions, or upper and lower cutter shaft input power simultaneously; Gear 5 engaged transmission that are 1 by a pair of speed ratio between upper and lower cutter shaft, upper and lower cutter shaft direction of rotation, branch feeds pulverizer by feed hopper 19, once branch is bitten by the cutter tooth of disc type cutter 8 on upper and lower cutter shaft, branch will inwardly be dragged by cutter tooth, and simultaneously cut and push by the front cutting edge of cutter tooth and left and right end face, until all cut off and pulverize, cutter has been held concurrently and has been fed and crushing function.Branch wood chip after pulverizing is discharged by discharge bucket 22.If the branch diameter of pulverizing is excessive, cause the cutter shaft of pulverizer to block, can, by electric or hydraulic means control prime mover reversion, cutter shaft be rotated backward, the branch blocking is exited.Noise when controlling operation, can select power to think that the hydraulic motor of coupling or motor are as prime mover according to operating environment.
Below disclose the present invention with better enforcement, so it is not intended to limiting the invention, all take to be equal to replace or technical scheme that equivalent transformation obtains, all drop in protection scope of the present invention.
