Embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is described further:
As shown in Figure 1 to Figure 2, a kind of ditching machine, comprise the frame 1 hanging on tractor rear, frame 1 front end is provided with driving shaft 11, gear-box 12 is provided with in the middle of driving shaft 11, tractor transmits power in gear-box 12 by the universal joint 18 being located at gear-box 12 front end, gear-box 12 drives driving shaft 11 to rotate, the side of frame 1 is provided with change gearbox 13, driving shaft 11 drives rotating shaft 14 to rotate by change gearbox 13, rotating shaft 14 is provided with main trench digging wheel 21, the groove that main trench digging wheel 21 is opened is main trench digging route, main trench digging wheel 21 is positioned at the centre of rotating shaft 14, rotating shaft 14 is respectively equipped with little trench digging wheel 22 in the left and right sides of main trench digging wheel 21, the axial location of two little trench digging wheels 22 in rotating shaft 14 is corresponding with wheel after two of tractor, here be interpreted as, when viewed from tractor dead ahead or dead astern, the position of little trench digging wheel 22 and the location overlap correspondence of tractor rear wheel, the advantage of such design is: on the track that tractor rear wheel runs over, little trench digging wheel 22 can travel one time again, thus ditched again in this part soil after compacting and loosen the soil, the groove that little trench digging wheel 22 is opened is micro-ditch, it not route of mainly ditching, so preferred, the diameter of little trench digging wheel 22 is less than the diameter of main trench digging wheel 21, certain trench digging resistance can be reduced like this.
As shown in Figures 3 to 5, free conversion is carried out according to different tractor model in order to the spacing between two little trench digging wheels 22 can be made, because the spacing between different tractor model trailing wheels is not identical, in order to make the scope of application of the present embodiment wider, in the present embodiment, the Position Design of two little trench digging wheels 22 in rotating shaft 14 is become adjustable structure, be specially: described little trench digging wheel 22 includes the axle sleeve 201 be fixed on by securing member in rotating shaft 14, axle sleeve 201 has open slot 2011, open slot 2011 is other is provided with two panels stator, be fastened by bolts between stator, when bolt unclamps, axle sleeve 201 can slide axially along rotating shaft 14, axle sleeve 201 is provided with operator attic base 202, on operator attic base 202, circumference is evenly distributed with the ditching knife 205 of more than 2.As preferably, described axle sleeve 201 is provided with time tool rest dish 203 in the both sides of operator attic base 202, and ditching knife 205, groove that secondary tool rest dish 203 circumference is distributed with more than 2 carries out trench digging with three tool rest dishes and loosens the soil, better effects if of loosening the soil or ditch.Main trench digging wheel 21 adopts this structure too, and main trench digging wheel 21 also can left and right adjusting if desired.
In order to strengthen the freely degree of repacking of the present embodiment further, the ditching knife 205 of the present embodiment is detachable, can according to different soil properties, landform carries out increasing or reduce ditching knife 205 quantity, being specially ditching knife 205 is fixed in tool rest 204 by securing member is detachable, slot 2041 is provided with in the middle of tool rest 204, can insert bottom ditching knife 205 in slot 2041, two sidewalls of slot 2041 are provided with through hole, ditching knife 205 is also provided with through hole simultaneously, ditching knife 205 is fixed in tool rest 204 by bolt successively these three through holes, the radical length of tool rest 204 is shorter, when ditching knife 205 is dismantled, tool rest 204 can not encounter soil when rotating with rotating shaft 14, tool rest 204 is fixed on operator attic base 202 or secondary tool rest dish 203 by the mode of welding, when running into soil property and being comparatively loose, the quantity of ditching knife 205 can be reduced to reduce trench digging resistance as far as possible, when running into soil and being comparatively hard, can suitably increase ditching knife 205.In addition, ditching knife 205 in the present embodiment is preferably as L shape bending structure, dogleg section is positioned at the end of ditching knife 205 away from rotating shaft 14 side, the wrap direction of adjacent two ditching knifes 205 of circumference is contrary, and the design of this ditching knife 205 and arrangement can make the distribution of the trench digging power in ditching knife 205 pairs of soils more even effectively.
In order to increase the soil-loosening function of this ditching machine to the region beyond main trench digging wheel 21 and little trench digging wheel 22, rotating shaft 14 is provided with the ditching knife 205 of more than 2 between main trench digging wheel 21 and little trench digging wheel 22, make whole ditching machine the effective area that loosens the soil of trench digging larger.And as preferred, the ditching knife 205 of more than 2 the helically stepped outer wall being distributed in rotating shaft 14 of formula centered by rotating shaft 14, the structure of spiral stepped distribution can allow the trench digging power of ditching knife 205 distribute in rotating shaft 14 ground evenly, only circumference is evenly, and axially also even.Equally, as preferably, the ditching knife 205 being positioned at this region is also detachable be fixed in rotating shaft 14, and specific embodiment mode is also insert in tool rest 204 by ditching knife 205, and then tool rest 204 is fixed on the outer wall of rotating shaft 14 by the mode of welding.It should be noted that, in Fig. 3 to Fig. 5, only on secondary tool rest dish 203, demonstrate tool rest 204, operator attic base 202 and rotating shaft 14 outer wall do not demonstrate tool rest 204.
In addition, this programme have also been made improvement to frame 1, a large amount of clod can be produced when considering that ditching machine is ditched splash, this kind of clod splashes in the groove that to be easy to when falling again to cover and to have held successfully, so the present embodiment mid frame 1 has installed a rear bar 15 additional at the rear of rotating shaft 14, rear bar 15 is connected with the connecting rod 16 of arc with frame 1 front end at driving shaft 11 place, connecting rod 16 also extends a segment length toward below, frame 1 is provided with 3 connecting rods 16, 3 connecting rods 16 corresponding main trench digging wheel 21 and two little trench digging wheels 22 respectively, connecting rod 16 is provided with gear mud backplate 17 in the rear side side of trench digging wheel and little trench digging wheel 22, the clod splashed can be blocked by gear mud backplate 17, can not be splashed in the groove held successfully at rear.
It should be noted that, be not limited to the afterbody being suspended on tractor when the utility model uses, the afterbody of other vehicles can also be suspended on, all replace with tractor for convenience of description in the utility model.
Below only with regard to the utility model preferably example be described, but can not be interpreted as it is limitations on claims.The utility model not only limits to and above example, its concrete structure allows to change, those skilled in the art can make various change and distortion according to the utility model, only otherwise depart from spirit of the present utility model, all should belong to the scope that the utility model claims define.
