Detailed description of the invention
By particular specific embodiment, embodiment of the present utility model is described below, person skilled in the art scholar the content disclosed by this specification sheets can understand other advantages of the present utility model and effect easily.
As shown in Figure 1 to Figure 3, the utility model provides a kind of micro-cultivator walking wheel mechanism, comprise two wheel rims be made up of steel 1, be arranged on the wheel hub 2 in wheel rim 1 and be fixed on multiple hinges 3 of wheel rim 1 periphery, the outside of two each and every one wheel rims 1 is provided with 3 to 6 contiguous blocks 14, and wheel hub 2 is arranged on the contiguous block 14 of one of them wheel rim 1 by bolt 13.By bolt 13 assembly connection, also make entirety have more while keeping bulk strength attractive in appearance, change the welding process of conventional boss 2, be convenient to wheel hub 2 and the installation of wheel rim 1, simplify production technology, cost-saving.Contiguous block 14 in this example on each wheel rim 1 is 4, and contiguous block 14 offers connecting bore, and two traveling wheel mechanisms like this can be combined by respective contiguous block 14 and install, increase traveling wheel mechanism width, strengthen the area of contact with ground, thus increase pressure, have more traffic potential.
The outline of wheel rim 1 cross-sectional plane is the trapezium structure that narrows from the width of width from the inside to the outside, in this example, wheel rim 1 is made up of diapire 11 and two side 12, the outer ring of two side 12 is connected with diapire 11, sidewall 12 is arc transition with the connecting portion of diapire 11, distance between two side 12 reduces from the inside to the outside gradually along wheel rim 1 radial direction, and its cross-sectional plane is
type, contiguous block 14 is welded on the inner side of sidewall 12, and hinge 3 is welded on the diapire 11 of two wheel rims 1, and in order to strengthen the intensity of wheel rim 1 in this example, wheel rim 1 adopts steel plate punched shaping.
As shown in Figure 4, as further optimization, two sidewalls 12 tilt to the direction away from diapire 11, and the angle that this sidewall 12 departs from wheel rim 1 place plane is 3 ° to 15 °, are preferably 5 ° in this example.Wheel hub 2 and hinge 3 shaping by steel plate punched, this wheel hub 2 forms reinforced rib 21 to lateral projections, and reinforced rib 21 is radial and circumference distribution along wheel hub 2.This structure is higher relative to wheel hub 2 intensity of flat board, plays good supporting role.
As shown in Figure 5, hinge 3 is uniformly distributed along wheel rim 1 circumference, these hinge 3 both ends are welded with wheel rim 1, inwardly give prominence in the middle part of hinge 3, and be stuck between two wheel rims 1, hinge 3 tilts to be located on two wheel rims 1, radial parallel with wheel rim 1, angle between this hinge 3 and wheel rim 1 axis is 20 ° to 45 °, and be preferably 30 ° in this example, namely this hinge 3 place plane and plane included angle, wheel rim 1 place are 60 °; Hinge 3 structure of said structure and angle thereof, make hinge 3 increase with the opposing force on ground, is convenient to muddy highway walking.
Because wheel rim 1 cross section outline is trapezium structure, for sheet forming forms in this example, other embodiments can be solid construction, relative to traditional steel ring, enhance the intensity of wheel rim 1, make its not easily deformed damaged, there is higher bearing capacity, strengthen the service life of traveling wheel mechanism.Wheel rim 1 and wheel hub 2 all adopt steel plate punched shaping, then by bolt 13 assembly connection, also make entirety have more attractive in appearance while keeping bulk strength, change the welding process of conventional boss 2, easy for installation, save cost.The hinge 3 of grabbing ground is also steel plate punched, and multi-disc combination forms an angle to be uniformly distributed with wheel rim 1 and welds, and when being used on tiller, left and right traveling wheel mechanism is symmetrical arranged.The large I arranging steel ring and wheel hub 2 changes the size specification of traveling wheel mechanism, for different types.This traveling wheel mechanism is arranged on tiller output shaft by axletree, for walking, is specially adapted to the environment that muddy section etc. needs increasing friction force.
Above-described embodiment is the principle of illustrative utility model and effect thereof only, but not for limiting the utility model, any person skilled in the art scholar all without prejudice under spirit of the present utility model and category, can modify above-described embodiment or change.Therefore, such as have in art and usually know that the knowledgeable modifies or changes not departing from all equivalences completed under the spirit and technological thought that the utility model discloses, must be contained by claim of the present utility model.
