Besides, the power transmission mechanism is a worm and gear power transmission mechanism, a worm gear is connected with a worm gear bracket, a planet gear set meshed with the left bevel gear and the right bevel gear are installed inside the worm gear bracket and comprises a planet bevel gear, and a left half shaft axis of the planet bevel gear and a right half shaft axis of the planet bevel gear are symmetrically arranged. Due to a differential mechanism which consists of the worm gear, the planet gear set and the like, the differential type walking post-positioned rotary cultivator is compact in structure and also raises the steering performance of the rotary cultivator.
Description
Technical field
The utility model provides a kind of hand steered rearmounted rotovator, belongs to agricultural mechanical field.
Background technology
Along with the construction of agricultural modernization, increasing farm machinery appears in the agricultural production, and rotovator is wherein a kind of, strong because of its hack ability, plough after the earth's surface smooth etc., obtained extensive utilization.The rearmounted rotovator of present hand-held has obtained great utilization in the knob, also more and more higher to its performance requirement.The rearmounted rotovator steering behaviour of present hand-held is poor, and the both sides wheels is just with identical rotational speed during turning, and it is difficult to turn, even can accelerate the wearing and tearing of wheel and drive disk assembly thereof.How improving in the turning to property of rotovator is exactly a problem of need waiting to solve.
Summary of the invention
For above-mentioned weak point of the prior art, the utility model provides a kind of differential type walking rearmounted rotovator, and compact conformation has improved the steering behaviour of the rearmounted rotovator of hand-held simultaneously.
The technical solution of the utility model is the rearmounted rotovator of a kind of differential type walking, comprise power drive mechanism and connected running gear, described running gear comprises the left and right half of coaxial line, be respectively equipped with left angular wheel, right bevel gear on the described left and right half, described power drive mechanism is the worm and gear power drive mechanism, described worm gear is connected with the worm gear carriage, be provided with the planet circular system that meshes with described left angular wheel, right bevel gear in the described worm gear carriage, described planet circular system comprises along the symmetrically arranged bevel planet gear of left and right half axis.
Further, be provided with the planet locating piece between the described bevel planet gear, described planet locating piece is provided with the planet major axis perpendicular to the left and right half axis; The planet locating piece is stretched out at described planet major axis two ends, and a planet bevel gear is respectively established at its two ends.
Further, also comprise the planet minor axis vertical with the planet major axis, and described planet minor axis is perpendicular to the left and right half axis; Described planet minor axis is two and conllinear, and two planet minor axises are an end and stretch out the planet locating piece, and respectively establishes a planet bevel gear on the external part; Bevel planet gear on the described planet major axis and the bevel planet gear on the planet minor axis are independent mutually.
Further, described each bevel planet gear all meshes with left angular wheel, and meshes with right bevel gear.
Further, be provided with pad between described bevel planet gear and the planet locating piece.
The beneficial effects of the utility model are: worm gear and worm gear carriage and the inner planet circular system with left and right bevel gear engagement thereof have consisted of a box of tricks, compact conformation not only, reduce small product size, the more important thing is that box of tricks is when rotovator turns to, driving force can be assigned on the left and right half with different speed, thereby improve steering behaviour.
Description of drawings
In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, the below will do to introduce simply to the accompanying drawing of required use in embodiment or the description of the Prior Art, apparently, accompanying drawing in the following describes only is embodiment more of the present utility model, for those of ordinary skills, under the prerequisite of not paying creative work, can also obtain according to these accompanying drawings other accompanying drawing.
Fig. 1 is the utility model STRUCTURE DECOMPOSITION schematic diagram.
Embodiment
Further describe the utility model below in conjunction with specific embodiment and accompanying drawing.
The rearmounted rotovator of a kind of differential type walking as shown in Figure 1, the rearmounted rotovator of a kind of differential type walking, comprise power drive mechanism and connected running gear, described running gear comprises the left side of coaxial line, right axle shaft, a described left side, be respectively equipped with left angular wheel 6 on the right axle shaft, right bevel gear 2, described power drive mechanism is the worm and gear power drive mechanism, described worm gear 5 is connected with worm gear carriage 1, be provided with in the described worm gear carriage 1 and described left angular wheel 6, the planet circular system of right bevel gear 2 engagements, described planet circular system comprise along left, the symmetrically arranged bevel planet gear of right axle shaft axis.
Further, be provided with planet locating piece 3 between the described bevel planet gear, described planet locating piece 3 is provided with the planet major axis 7 perpendicular to the left and right half axis; Planet locating piece 3 is stretched out at described planet major axis 7 two ends, and a planet bevel gear is respectively established at its two ends.
Further, also comprise the planet minor axis 4 vertical with planet major axis 7, and described planet minor axis 4 is perpendicular to the left and right half axis; Described planet minor axis 4 is two and conllinear, and two planet minor axises 4 are an end and stretch out planet locating piece 3, and respectively establishes a planet bevel gear on the external part; Bevel planet gear on the described planet major axis 7 and the bevel planet gear on the planet minor axis 4 are independent mutually.Increased planet minor axis 4 and on bevel planet gear, structure is more stable.
Further, described each bevel planet gear all meshes with left angular wheel 6, and meshes with right bevel gear 2.
Further, be provided with pad 8 between described bevel planet gear and the planet locating piece 3.Reduce the wearing and tearing between bevel planet gear and the planet locating piece 3, increased service life.
The utility model is when doing straight line moving, and planet circular system is stressed evenly, and the worm gear carriage 1 that only drives along with worm gear 5 revolves round the sun, thereby the rotating speed that is transferred on the left and right bevel gear is identical, and then the left and right half rotating speed is identical; When turning, the planet circular system discontinuity, simultaneously rotation during revolution, just different with the number of turns of left and right bevel gear engagement rotation like this, left and right half will produce differential so, the convenient turning.
More than technical scheme that the utility model embodiment is provided be described in detail, used specific case herein principle and the embodiment of the utility model embodiment are set forth, the explanation of above embodiment is only applicable to help to understand the principle of the utility model embodiment; Simultaneously, for one of ordinary skill in the art, according to the utility model embodiment, all will change on embodiment and range of application, in sum, this description should not be construed as restriction of the present utility model.
