Form by following structure referring to Figure 11, Figure 12, Figure 13, the brush cleaning assembly of this chain of Figure 14; Be respectively arranged with and relative sweep that beam 50 terminations are that beam 50 is swept in cantilever-shaped and clamping and the affixed sprocket wheel axle bed 51 on it of symmetry sweeping beam 50 two ends, promptly sweep beam 50 two ends be separately positioned on the sprocket wheel axle bed 51 by bearing 52, the sprocket shaft 53 of rotating support on sprocket wheel axle bed 51, sweep that rigidity is connected with sprocket wheel 54 on the sprocket shaft 53 at beam two ends, sprocket shaft 53 is connected with motor power output shaft 57 splines that are used for the synchronous hydraulic motor 56 that drive sprocket rotates that are fixed on by interfacing part 55 on the sprocket wheel axle bed 51; Edge sweeping on the beam 50 perpendicular to sprocket shaft 53 directions, on following two faces with respect to the chain traffic coverage between two sprocket wheels, be symmetrical in and sweep beam 50 settings, and be fixed on the middle guide of sweeping on the beam 58 of controlling the chain linear running with parallel being used to of two sprocket wheel wheel faces that has, and branch is located at the U-shaped rail brackets 59 of middle guide 58 both sides, be installed with notch on the U-shaped rail brackets 59 and be used to limit the U-shaped guide rail 60 of chain degree of speeding towards sprocket wheel 54 wheel faces, has chain 61 with sprocket wheel 54 engagement installings, each of chain 61 adds chain link shaft 63 shaft ends that grow to outer chain sheet 62 two ends and all is symmetrically installed with rolling bearing 64 or roller, it is symmetricly set on rolling bearing 64 rolling-operation U-shaped guide rail 60 on the chain link shaft 63 during with sprocket wheel 54 jogglewords at chain 61, and it rides on the middle guide 58 realization chain 61 at the guide rail section linear running thereby the outer chain sheet of chain 61 62 is for inverted trapezoidal structure; Distolateral at outer chain sheet 62 lengthy motion pictures of chain 61 also because of bristle 65 is housed, be the lengthy motion picture that steel brush hair 65 is fixed on outer chain sheet 62 is distolateral in this example by U-shaped fastener 66.

Referring to Fig. 1, Fig. 2, Fig. 3, this multifunctional snow cleaner of Fig. 4 is hung to connect with the power-equipment loader and only can be finished by the butt joint body 9 of this device, promptly on butt joint body 9, be fixed with a pair of butt joint clamp 67, utilize the rear overhang end spill mouth of butt joint clamp 67 to be stuck on the cross-arm of the rocking arm journal stirrup 68 on the loading arm, utilizing the loader rocking arm to wear pin 69 again will dock clamp 67 dumplings and connect to hang and be connected on the loader rocking arm journal stirrup 68, just be combined into snow blower after finishing butt joint with multifunctional snow cleaner, phase one mistake that clears the snow can be decomposed the former function that the function of recovering motive power equipment is promptly recovered loader easily, improves usage ratio of equipment.The hydraulic power supply of all hydraulic cylinder and hydraulic motor provides by loader (power-equipment) in this device, because of hydraulic system is a known technology, so be not described in greater detail in this snow cleaner.Making snow cave shovel assembly and the relative loader direction of advance of cleaning assembly angle α after this device and loader 1 company of extension is 50 °, also can utilize this angle guiding mechanism between 46 °～65, carry out the angle adjustment, to change the snow-removing operation fabric width; Be 75 °, can utilize dip angle adjusting mechanism in 80 °～55 ° scopes, to adjust in the angle of inclination beta of common three sections snow cave shovels of operation situation with respect to ground line.Cleaning assembly and Horizon and be angle and be obliquely installed bristle and land, its angle Γ is arranged between 45 °～55 °

The utility model has the advantage of:

One, the snow cave shovel assembly combines for three sections shovels of overlap joint successively, because being flexible connection between each section shovel, The shovel elevating mechanism can adapt to road surface arc comprehensively in having, and tail shovel can be easily and tail shovel with throwing device Exchange, and increase the function that clears the snow, the dip angle adjusting mechanism of snow cave shovel can according to the road snow situation (snow slab, floating snow, Sleet) adjust snow cave shovel shovel snow angle, when road surface arc changes, move on the middle shovel, initial and end two shovel relatively with Move and relatively rotate around ball-joint, the approximate road surface arc that tough the formation of snow cave shovel on contact road surface is made of three sections straight lines The camber line of degree, the increase snow cave shovel contacts with the road surface, thereby has guaranteed snow-removing effect, and accumulated snow can during snow-removing operation Prolonging smoothly the oblique right side of snow cave shovel slides and turns over to the roadside or change by tail shovel of paddle blower and dish out.

Two, the cleaning assembly is arranged on after the snow cave shovel assembly, directly preceding working procedure snow cave shovel residue is later cleaned without the residual snow of spreading on a small quantity, when cleaning work, can give earlier elevating mechanism adjustment bristle with the cleaning assembly (contact road surface) dynamics that lands, because the speed of service of chain wheel drive chain brush is greater than pace, has bionical effect, and oblique setting, sprocket wheel turns to the power-equipment wheel and turns to the oblique from left to right cleaning running of drive chain brush substantially in the same way, thereby resistance is little in the operation of advancing, mechanical effect is not fully exerted, cleaning work simulates bionical naturally, just sweep to opposite side by a side with the broom cleaning as personnel, owing in advancing, implement cleaning with the brush machinery of the chain of fast turn-around, the bristle that lands below all run to all is in duty, continuously snow is swept to right lateral side, so the efficient height, quality is good.

Three, the overall apparatus that is also advantageous in that this multifunctional snow cleaning is put is arranged on before the power-equipment loader, docking mode is simple, easily observe just operation during snow-removing operation, whole snow-removing operation carried out before the power-equipment train, there is not self train spreading accumulated snow and forms local snow slab once again and the phenomenon of unfavorable cleaning, shovel, sweep the angle of adjusting synchronously in the assembly use with the snow blower direct of travel, with the change fabric width that clears the snow, when snow-removing operation is turned, when snow cleaner and power-equipment loader during not on a plane, displacement can be rotated relative to loader in the docking site that the flange of snow cleaner connects, realize the omnibearing stereo profiling of whole snow cleaner, with and guarantee the shovel, sweeping assembly keeps normal work to contact with the road surface, whole snow-removing operation shoveled before the power-equipment train, sweep away snow and finish synchronously, the efficient height, quality is good, and the road surface sees the bottom.Shovel during non-snow-removing operation, sweep assembly and can lift away from ground maneuver and travel, winter, snow cleaner can decompose with loader easily later, recover the function of motive power equipment loader, improve usage ratio of equipment, so this multifunctional snow cleaner is the snow clearing equipment of less expensive type, be applicable to that urban highway, speedway, civilian, military airfield large tracts of land in winter clear the snow.
