Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in further detail:
As shown in Figure 1, Figure 2, shown in Fig. 3, Fig. 4 and Fig. 6, a kind of wood chipper, comprise base 1 and the fore-stock 3 be located on base 1 and after-poppet 4, housing 2 is provided with in the front of after-poppet 4, discharging opening 7 is provided with on housing 2 top, be provided with charging aperture 8 in housing 2 bottom, the center on housing 2 is provided with air holes 11, and fore-stock 3 is positioned at the front portion of housing 2, after-poppet 4 is provided with main shaft 9 by bearing mounting base 12, and the front end of main shaft 9 is stretched into housing 2 inside and is provided with blade wheel seat 10, and on blade wheel seat 10, uniform being provided with cuts wooden cutter 18, base 1 is provided with mair motor 5, and mair motor 5 is connected with main shaft 9 by cog belt connecting gear 6, between housing 2 and blade wheel seat 10, inside is provided with sieve 14, two parallel upper feed rolls 19 and lower feeding roller 20 is provided with in charging aperture 8 inside, upper feed roll 19 and lower feeding roller 20 are stretched out by charging aperture 8, bearing block 21 is respectively equipped with in charging aperture 8 both sides that are positioned at of upper feed roll 19 and lower feeding roller 20, sprocket wheel 24 is provided with in one end of lower feeding roller 20, sprocket wheel 24 is connected with the feeding motor 13 be located on base 1 is logical by chain, the position of the corresponding upper feed roll 19 in the both sides on charging aperture 8 is provided with slideway 22, the bearing block 21 at upper feed roll 19 two ends is located in slideway and also can slides along slideway, two bearing blocks 21 at upper feed roll 19 two ends are connected by the suspension bracket 25 be positioned at above charging aperture 8, spring 23 is provided with between the upper center and charging aperture 8 upper end of suspension bracket 25.
As shown in Figure 5, cutterhead wheel disc is by center 16 and cut wooden cutter mount pad 17 and form, cutting wooden cutter installation 17 is 15 to 18 ° of angles with the normal direction of center 16, arrange such angle installation can be made to fix after the cutting entrance angle cutting wooden cutter 18 more suitable, convenient cutting, avoids the blade damage of cutting wooden cutter 18.Cut in wooden cutter 18 and be provided with wedge-shaped impression, cut wooden cutter 18 and embed in groove, be fixed on by bolt 15 and cut in wooden cutter mount pad 17.
As shown in Figure 7, A point to the B point cutting the knife back place of wooden cutter 18 is by a horizontal linear, B point is hyperbola to C point, and straight line and hyperbola form B point is tangent, when mounted, straightway and hyperbolic line segment and groove fit, owing to there is hyperbolic line segment, can make to cut wooden cutter 18 and slip into the inside, convenient installation is as groove, easy location, is then fixed by bolt 15.
First the blade cutting wooden cutter 18 is multistage curve combination, be sine curve from C point to D point curve, take the sinusoidal segments that sine curve 90 to 150 is spent, the C point cutting wooden cutter 18 is the initial segment starting to cut to D point sinusoidal segments, sinusoidal segments can optimize cut-in angle more, effective incision, improves stock-removing efficiency, improves blade life.D point is in involute to the curve of E point, and involute section curve is in working angles, progressively deep segment of cutting, and involute curve effectively can improve cutting speed, reduces resistance.E point is hyperbola to the curve of F point, the effective section in hyperbola section working angles, and F point is to G point involute curve section, and four sections of curves are tangent to be successively formed by connecting, and is provided with profile of tooth blade from G point to H point; Cut wooden cutter 18 blade from C point to D point place, the angle of blade and horizontal direction is 20 to 22 °.Cut wooden cutter 18 blade from D point to E point place, the angle of blade and horizontal direction is 22 to 25 °.Cut wooden cutter 18 blade from E point to F point place, the angle of blade and horizontal direction is 25 to 27 °.Cut wooden cutter 18 blade from F point to G point place, the angle of dentation blade horizontal direction is 24 to 27 °.
Wood chipper in use, can run into the material of different-thickness size, will consider multiple application, also will consider the problems such as efficiency, cutting speed and cutter life simultaneously arranging of blade.The C point cutting wooden cutter 18 is the initial segment starting to cut to D point sinusoidal segments, first effectively cut, D point is further deeply cut to the involute curve of E point, E point is the most effective segment of cutting to the hyperbolic line segment of F point, for the material of general thickness, in working angles, after E point to the hyperbolic line segment of F point, the blade cutting wooden cutter 18 is converted to from incision the stage of exiting, E point is converted to the involute curve of D point to E point to the hyperbolic line segment of F point, involute curve facilitate progressively exiting from being cut object of blade, after C point to D point sinusoidal segments, blade exits and is cut object.For the material that thickness more strengthens, cut wooden cutter 18 and additionally provide F point to G point involute curve section, as alternative section, the material large for thickness cuts.Profile of tooth blade is provided with also as alternative section, as the cutting of certain material to H point from G point.
In use, first mair motor 5 is connected, mair motor 5 drives main shaft 9 main shaft 9 driven rotary blade wheel disc 10 to rotate by cog belt 6, run 3 ~ 5 minutes, open feeding motor 13, feeding motor 13 drives lower feeding roller 20 to rotate, after steady running, the timber that band cuts is put into charging aperture 8, under the effect of suspension bracket 25 inner spring 23, timber compresses by upper feed roll 19, timber is under the effect of lower feeding roller 20, at the uniform velocity enter in housing 2, enter the timber in housing 2 simultaneously, wood chip is whittled into by the wooden cutter 18 of cutting of High Rotation Speed, the wood chip cut flies out from the space of sieve 14, the outside of housing 2 is thrown to via discharging opening 7.
Because cutting power of cutting wooden cutter 18 of the present utility model is better, the operating efficiency of wood chipper is promoted greatly, extends the service life of cutting wooden cutter self.The air holes 11 that housing 2 is provided with, when blade wheel disc 10 High Rotation Speed, adds the intake of housing 2 inside, defines the structure of approximate blower fan, because of this increase wood chipper outwards throw wood chip throw ability.In addition owing to being provided with upper feed roll 19 and lower feeding roller 20 at charging aperture 8, what material was transported enters housing 2 inside, and therefore can either clamp timber again can uniform speed feeding.
Although embodiment of the present utility model is open as above, but it is not restricted to listed in description and embodiment utilization, it can be applied to various applicable field of the present utility model completely, for those skilled in the art, can easily realize other amendment, therefore do not deviating under the universal that claim and equivalency range limit, the utility model is not limited to specific details and illustrates here and the legend described.
