Abstract
The utility model belongs to the field of walking tractors, and particularly relates to a road wheel of a walking tractor. The road wheel of the walking tractor comprises a rim and a spoke, wherein the spoke and the rim are connected, blades are circumferentially arranged on the rim, and a round ring is arranged at the outer edge protruded out of each blade. According to the road wheel of the walking tractor, which is disclosed by the utility model, the blades are circumferentially arranged on the rim of the road wheel, and the round ring is arranged at the outer edge protruded out of each blade, so that the round ring is in contact with the ground mainly when the walking tractor with the road wheels runs on a hard road, and a situation that the walking tractor with the road wheels bumps on the hard road caused by the fact that a connection line of the outer edges of the blades is in a polygon shape is avoided; because the round ring is directly in contact with the ground and bears the pressure and the friction force when the walking tractor with the road wheels runs on the hard road, the blades are prevented from being seriously worn; therefore, the service lives of the blades are prolonged.
Description
Technical field
The utility model belongs to the walking tractor field, relates in particular to the walking tractor road wheel.
Background technology
Along with scientific and technological development, the agricultural planting machinery degree is more and more higher.At present, for the small size farming, mostly use walking tractor to complete the operation of digging, and the walking tractor road wheel is the important component part of walking tractor.As in the application number patent document that is 201020225886.7, disclosed road wheel, by rotating shaft, the gear teeth, spoke and wheel rim, formed.Be characterized in having and cut native function and be difficult for being stained with band earth.But still also have in actual use weak point: 1,, can jolt and advance always when hard surfacing travels when the walking tractor that is equiped with this road wheel.2, when hard surfacing travels this road wheel of use, its road wheel, easily by severe wear, greatly reduces service life.
The utility model content
The utility model provides a kind of walking tractor road wheel of walking tractor in hard surfacing smooth-ride and long service life that can allow.
In order to solve the problems of the technologies described above, the utility model provides following technical scheme: the walking tractor road wheel comprises wheel rim, spoke, spoke is connected with wheel rim, circumferentially be provided with blade on wheel rim, on the outer rim of described blade, offer groove, annulus is fastened in groove.
Adopt technique scheme, in the utility model, because circumferentially be provided with blade on the wheel rim of road wheel, bulged blade outer rim place is provided with annulus, like this when hard surfacing travels mainly by the annulus kiss the earth, having avoided was originally that a polygon causes jolting when hard surfacing travels because of blade outer rim line; Because when hard surfacing travels, the direct kiss the earth of annulus, bear pressure and friction force, thereby protect blade not by severe wear, thereby increase the service life.
Further, described annulus is steel ring.Such design can make annulus pressure resistance and more wear-resisting.
The accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail:
Fig. 1 is the structural representation of the utility model walking tractor road wheel.
The specific embodiment
As figure, the walking tractor road wheel, comprise wheel rim 2, spoke 1, and spoke 1 is connected with wheel rim 2, circumferentially is provided with blade 4 on wheel rim 2, and blade 4 tilts towards sense of motion, and bulged blade 4 outer rim places are provided with annulus 3.
Circumferentially be provided with blade 4 on the wheel rim 2 of road wheel, can better cut in the fields earth during operation and avoid a large amount of earth of adhesion, bulged blade 4 outer rim places are provided with annulus 3, like this when hard surfacing travels mainly by annulus 3 kiss the earths, having avoided was originally that a polygon causes jolting when hard surfacing travels because of blade 4 outer rim lines; Because when hard surfacing travels, the direct kiss the earth of annulus 3, bear pressure and friction force, thereby protect blade 4 not by severe wear, thereby increase the service life.
In order to make annulus 3 more wear-resisting strong with compressive resistance, allow the annulus 3 used, it is steel ring.
At protrusion 4 blade outer rim places, an annulus 3, the pressure that balance annulus 3 is suffered are installed again again for convenient.Offer the groove be complementary with annulus 3 on the outer rim of blade 4.
Above-described is only preferred implementation of the present utility model; should be understood that; for a person skilled in the art; under the prerequisite that does not break away from the utility model structure; can also make some distortion and improvement; should be considered as protection domain of the present utility model, these can not affect effect and practical applicability that the utility model is implemented yet.
