Description

Auger of saw-type snow sweeper

The present invention relates to a kind of auger of saw-type snow sweeper, belong to mechanical engineering technical field, be applicable to the cutting and crushing of road pavement accumulated snow and ice and snow, rapidly and efficiently, do not damage the road surface.

The northern part of the country of coming whenever winter, long-pending streets and lanes, the road of having expired of heavy snow rolled over through people's treadmill and to be condensed into ice and snow, and be very hard smooth, causes great difficulty and danger for the people's life and trip, removes the burdensome task that ice and snow on road surfaces just becomes each city.Although existing drum-type, agitator type snowplow are developed a collection of novel snowplow in recent years both at home and abroad again in succession, this special ice and snow of their road pavement is all done nothing.Make a general survey of the effect of all kinds of snowplow road pavement ice and snow, can be divided into following a few class by operating principle.

One. agitator type, drum-type snowplow: agitator type and drum-type can be cleared away the accumulated snow on road surface well, but just fully powerless to successively stepping on the special closely knit hard ice and snow that vehicle roll over to form through the pedestrian, at this moment snowplow has only become manually to cut the loader that shovel is piled up ice and snow.

Two. paddle type mill, marking knife formula, tine formula snowplow: hammer, marking knife, tine are feature to hit ice and snow from top to bottom, because ice and snow is subjected to the support on road surface and in conjunction with closely, this hitting power major part is offset by the road floor, power consumption is big, inefficiency, particularly their badly damaged road surfaces of meeting have determined that this class type is difficult to promote.

Three. milling cutter formula, steel brush formula snowplow: the former uses the principle of milling machine, like plodding away at a big job bit by bit ice and snow is little by little cut; The steel brush formula also only can be cleared away the ripe snow on road surface, for ice and snow is softening, generally adopts the way of salting both at home and abroad, yet such ice and snow can dissolve into the very big salt solution of concentration, it flows to where flowers and plants will wither, and it is dead that trees are wanted, and our environment will be paid huge cost for it.

With the mechanical removal ice and snow on road surfaces is a global difficult problem always, and the snowplow front end more becomes the long-term core of tackling key problems of various countries inventors to the system that ice and snow carries out broken cutting, must solve two big technical barriers in order to solve this difficult problem: one, special hard ice and snow there is good broken cutting function, makes it effectively to separate with the road surface; Its two, the nothing of the safety of machinery and road pavement is damaged, even slightly also will accomplish to work reliably in the road surface of Qi Fuing.Saw is a kind of important tool, and timber, steel, stone material are had good dissection.One big characteristics of ice are fragility, at first sawtooth it are done the time spent, stay groove mark one after the ice bits fly out, and can produce many small crackles simultaneously about reaching below this road groove mark; Second adjacent sawtooth work of the right makes the ice and snow between the twice groove mark broken apart with it, can produce new crackle again simultaneously, and sequential working will make the ice and snow on road surface obtain fragmentation according to this.Purpose of the present invention is exactly the deficiency that will overcome all kinds of snowplows, utilize the good characteristic invention road pavement ice and snow of saw to carry out the broken removing of fly-cutting, can remove ice and snow on road surfaces with machinery with existing snowplow, cleaning cart, the combination of hand steered four-wheel tractor, the real realization again, improve the traffic of north of china in winter at all and improve the people's quality of life.

The present invention is achieved like this: auger of saw-type snow sweeper cuts several parts such as saw blade, rotating shaft by special-shaped saw blade, stealthy reverse side to be formed, and when special-shaped saw blade was oval, profile of tooth can be a pointed shape, also can be several profiles of tooth that cutting tile, stone material are used saw blade.There is an angle position of abnormity saw blade with rotating shaft on long axis direction, make the distance of major axis two-end-point between the projection in the rotating shaft at 5-20 centimetre, and making the width of each tooth cutting is optimum value.The cutting edge of sawtooth has rectangle, single beveled, double inclined plane shape, each group tooth when work and rotating shaft are perpendicular, and the radius of each tooth countershaft all equates, in order to prevent once to repeat cutting raising the efficiency, be tooth about axis of symmetry has front and back between the projected position in the rotating shaft branch with the saw blade major axis in same point.Saw blade also can adopt single screw feeder, twin screws, three screw feeder modes, and the width of each week cutting is between 5-20 centimetre, and each tooth all should be perpendicular with rotating shaft.Two ends and middle part arrange that several stealthy reverse side cut saw blade, thickness is greater than 3 millimeters, convex concave tooth reversed arrangement is on two side circle walls, the saw of this profile of tooth removes has good dissection to ice and snow, because it is thicker, circumference is smooth, the diameter of sawtooth is slightly less than the diameter that stealthy reverse side is cut saw blade in addition, so play supporting role again to the class drum, and safety when guaranteeing the work of special-shaped saw blade ground proximity, the road surface do not damaged.Rotating shaft is by the end axle at middle shaft part, two ends, and the tooth axle is formed, and middle shaft part is used to install and fix special-shaped saw blade and stealthy reverse side is cut saw blade.Tooth axle and end axle rotate except making the class drum, and the convex concave tooth on the tooth axle is given operate portions with the power transmission of machine again, and the position the when locating wheel on tooth axle and the end axle makes rotating shaft work is move left and right not, makes the screw feeder working stability.

Figure one is the auger of saw-type snow sweeper schematic diagram; Figure two special-shaped saw blades and profile of tooth figure; Figure three stealthy reverse side are cut saw blade figure.

Auger of saw-type snow sweeper of the present invention is existing further to be described in conjunction with figure one, figure two, figure triple-cropping.1 special-shaped saw blade among the figure; One of 2 profiles of tooth; Two of 3 profiles of tooth; Three of 4 profiles of tooth; Four of 5 profiles of tooth; Five of 6 profiles of tooth; 7 rectangular teeth cutting edges; 8 monocline face land mouths; 9 double inclined plane land mouths; 10 stealthy reverse side are cut saw blade; 11 convex teeth; 12 spill teeth; 13 rotating shafts; 14 tooth axles; 15 end axles; 16 locating wheels; 17 installing holes.Oval special-shaped saw blade 1 is tilting in rotating shaft at long axis direction, and all teeth are all perpendicular to rotating shaft, and vertical width is 5-20 centimetre, for increasing work efficiency, the distance of tooth between the projection in the rotating shaft that is positioned at major axis left and right sides same position should be the 4-6 millimeter, can select one of profile of tooth 2 for use to the cutting of all kinds of ice and snow, 23 of profile of tooth in order to adapt to, 34 of profile of tooth, 45 of profile of tooth, 56 of profile of tooth, the cutting edge of tooth can be a rectangle cutting edge 7, monocline face cutting edge 8, double inclined plane cutting edge 9.Discharge from tooth for the ease of the snow bits, be circular in the profile of

tooth

2,3,4,5, saw blade also can adopt single screw feeder, twin screws, three screw feeder modes except that using special-shaped saw blade 1, but all require each all cutting width between 5-20 centimetre, all flank of tooth are all perpendicular with rotating shaft.Convex tooth 11, spill tooth 12 reversed arrangement cut in stealthy reverse side on the two sides circles wall of saw blade 10, and the thickness of saw blade is greater than 3 millimeters, adopt 2,3 or several pieces according to the length of screw feeder, and circumferential surface is smooth.And its diameter should be not less than 2 millimeters greater than the rotation diameter of tooth, so it plays a supportive role to screw feeder; Ground proximity has good cutting and crushing effect to ice and snow; Guarantee the safety of machine and do not damage the road surface.Installing hole 17 is used for saw blade 1,10 and installs in rotating shaft 13.Rotating shaft 13 move left and right were stable when making screw feeder work when the locating wheel 16 on tooth axle 14, the end axle 15 was used to prevent work.Tooth axle 14, end axle 15 rotate rotating shaft 13 reliably, be furnished with the convex concave tooth on the tooth axle 14 power of machine is transferred to screw feeder work reliably.
