Abstract

The utility model relates to a hoeing wheel of small walking tractor, which belongs to the accessory of the small walking tractor, having a flange disc. The outer side end face of the flange disc is welded with at least two cutter heads by a steel tube and /or a connecting plate. The cutter heads are separated at a distance axially, and the centerline of the cutter heads is coincident with the centerline of the flange disc. Bent blades which are mutually staggered in a certain angle are fixed on the flange disc and the circumferential direction along the flange disc on the cutter heads. The utility model can be used as the driving wheel of the small walking tractor and also can be used as a tool for hoeing, tilling and harrowing, the hoeing wheel of the small walking tractor has dual functions of the driving wheel function and a rotary tilling hoe function, in particular is suitable for dry field to be planted dry crops such as sugarcane, corn, peanut, soybean, etc. The utility model is suitable for the operation at dry paddy field without water for plowing, preparing the field, harrowing, etc.

Description

The small hand tractor wheel of hoing the fields

Technical field

The utility model relates to a kind of accessory of small hand tractor, the accessory of particularly little Taurus hand tractor.

Background technology

The driving wheel of present existing hand tractor is the anti-pulley of rubber tire or steel mostly, and these can only be used as the drive that hand tractor travels, and do not have the function of plowing, putting in order ground and raking the soil level.

Summary of the invention

Task of the present utility model is the shortcoming that will overcome the driving wheel of existing hand tractor, provide a kind of when can be used as driving wheel, can be used as again hoe the fields, many usefulness of whole ground and the instrument of raking the soil level are hoed the fields driving wheel.

The utility model is finished like this: it also has a flange, at the outside of flange end face, be welded with the central lines of at least two its center lines and flange, the cutterhead of axially-spaced certain distance with steel pipe and/or connecting plate, the circumferencial direction of flange and cutterhead upper edge flange is fixed with the tulwar of the certain angle that staggers each other.

Because there are a plurality of cutterheads on the side of the utility model flange side, be fixed with many on each cutterhead again tulwar, thereby its tulwar gabarit can become a cylindrical shape, it just not only can be used as driving wheel like this, can be used as again simultaneously hoe the fields, rotary tillage wheel that many usefulness of whole ground and the instrument of raking the soil level are hoed the fields, be particularly suitable for grow cane, the dried ground of dry crops such as corn, peanut, soya bean and do not have the solid carbon dioxide Tanaka of water to plow, the usefulness of whole ground, operation such as rake the soil level.

The drawing explanation

Fig. 1 is the structural representation of an embodiment of the utility model.Fig. 2 is that the A of Fig. 1 is to view.Fig. 3 does not draw the flange of bolt and the A that goes up fixing tulwar thereof to view.Fig. 4 be do not draw bolt near first cutterhead in the flange outside and the A that goes up fixing tulwar thereof to view.Fig. 5 does not draw second cutterhead in the flange outside of bolt and the A that goes up fixing tulwar thereof to view.Fig. 6 does not draw the cutterhead of flange inboard of bolt and the A that goes up fixing tulwar thereof to view.

Embodiment

With reference to attached Fig. 1 and 2, centre at the inner face of foursquare flange 1, the counterbore 2 that can be connected with the reel of small hand tractor driving wheel is arranged, the outside end face of flange 1, be welded with the central lines of its center line and flange 1 with steel pipe 3 and trapezoidal connecting plate 4, the axially-spaced certain distance, the size of profile and identical first cutterhead 5 of specification with flange, at the outside of first cutterhead 5 end face, be welded with the central lines of its center line and flange 1 with steel pipe 6, the axially-spaced certain distance, the size of profile and identical second cutterhead 7 of specification with flange, between first cutterhead 5 and the flange 1, along the circumferencial direction of flange 45 degree that stagger, between first cutterhead 5 and second cutterhead 7, along the circumferencial direction of flange 45 degree that also stagger.Be preferably in the inner side end of flange 1, weld central lines, axially-spaced certain distance, the size of profile and the 3rd identical cutterhead 9 of specification and flange of its center line and flange again with the connecting plate 8 that reverses miter angle, on foursquare four angles of flange and each cutterhead, all be fixed with a tulwar 10, so on flange and each cutterhead, just be fixed with four tulwars, like this, tulwar is just along the circumferencial direction of flange certain angle that staggers each other.Tulwar 10 all is to make the identical rectangle of shape and size with the high-quality spring steel band steel section of 8 millimeters thickness, and its leading portion curves quadrant, and a side of leading portion or opposite side have and be not very sharp, approximately the blade 11 of two millimeters thickness arranged.Such as the left side blade being arranged is positive tulwar blade, and it is the recurvation cutter blade that there is blade on the right side.When tulwar was installed on flange and each cutterhead, blade all will be towards the place ahead of direction of rotation.It shown in Fig. 1 the hoe the fields view of wheel of the right side of small hand tractor.On flange 1, first cutterhead 5 and the 3rd cutterhead 9, symmetry is installed positive and negative two groups of tulwars respectively, radially becomes the involute formula.On second cutterhead 7, positive tulwar is installed, radially also become the involute formula.Like this, the right side hoe the fields the wheel on 10 positive tulwars, 6 are arranged the recurvation cutter, a left side hoe the fields the wheel on 6 positive tulwars, 10 are arranged the recurvation cutter.
