Description
Technical field
The invention belongs to Miniature tilling implement technical field, specifically, more particularly to a kind of narrow micro-cultivator walking wheel knot
Structure.
Background technology
Vigorously supporting and develop with mechanization of agriculture, mini-tiller using increasingly increased extensive.Mini-tiller due to
The features such as light-weight, small, simple in structure, behaviour facilitates is suitble to the hillside fields of the vast Hills in China and ploughing for splat
Make, it is deep to be liked by users.
At present, the traveling wheel of mini-tiller is generally using wide cut rubber wheel, it is larger with the contact area on ground, easily by ground
Compaction by rolling is unfavorable for the root growth of crop.Meanwhile existing micro-cultivator walking wheel grab ground effect it is bad, one in ploughing work
Reinforcing is easy for idle running occur, runs ridge phenomenon, thus limits utilization rate of the mini-tiller in hillside fields.Some mini-tillers are in traveling wheel
Excircle on add ground pawl, although increasing earth-grasping force, ground pawl is mostly wedge shape, on the one hand meets the hard object such as stone and easily sends out
Raw damage, on the other hand increases resistance during farming, makes operation more laborious, so as to reduce farming efficiency.
Some micro-cultivator walking wheels use metal structure, wheel hub including steel ring, in steel ring and mounted on steel ring
The hinge of periphery, steel ring are the sheet of circular ring shape, if intensity is compared with easily overload causes steel ring to damage after long-time service；And
The traveling wheel processing technology of this all-metal construction is complicated, of high cost, and relative rotation, reliability are also easy to produce between wheel hub and wheel shaft
It is poor.
Invention content
In view of the drawbacks described above of the prior art, the technical problems to be solved by the invention are to provide a kind of narrow mini-tiller
Walking wheel construction.
Technical solution of the present invention is as follows：A kind of narrow micro-cultivator walking wheel structure, including wheel rim and wheel hub, wheel rim is by rubber
It is made, it is characterised in that：The width of the wheel rim is 50-70mm, and radial direction boss is evenly distributed on the outer circumference surface of wheel rim,
The outer end face of the radial direction boss is arc surface, and the center of circle of circumference is overlapped with the center of circle of wheel rim where radial direction boss outer end face,
Both sides in the middle part of the radial direction boss are symmetrically arranged with side boss, and the side and radial direction boss of the side boss and wheel rim are linked as one
Body, the outer end face of the outer end face of side boss and the radial direction boss are located on same periphery, the inner face of side boss with it is described
The inner peripheral surface of wheel rim is located on same circumference；
Be coated with steel skeleton in the wheel rim, the steel skeleton is circular ring structure, the center of circle of the steel skeleton with
The center of circle of wheel rim overlaps, and multiple equally distributed female connectors, one end of the female connector are provided on the inner peripheral surface of steel skeleton
It is mutually fixed with steel skeleton, the other end of female connector exceeds the inner peripheral surface of wheel rim；
The reinforcement structure being distributed by even circumferential, the reinforcement structure and the radial convex are provided on the steel skeleton
Platform is arranged at intervals, and the reinforcement structure strengthens boss by radial direction and lateral boss of strengthening forms, and radially strengthens boss and is located at steel
On the outer circumference surface of skeleton, each both sides for radially strengthening boss are symmetrical arranged lateral reinforcement boss, and lateral boss of strengthening is located at
On the side of steel skeleton；
The wheel hub is located at the center of wheel rim, and multiple wheels by even circumferential distribution are equipped between wheel hub and wheel rim
Spoke, the spoke are steel-tube construction, and one end of spoke is mutually fixed with wheel hub, and the other end of spoke is inserted in female connector, the female connector
In wheel rim.
The present invention is narrow structure, and width only has 50-70mm, greatly reduces the contact area with ground in this way, make ground
Face is small by the region of compaction by rolling, thus effectively reduces the adverse effect to crop root growth.On the outer circumference surface of wheel rim
Even distribution radial direction boss, the radial direction boss play a part of to increase earth-grasping force, to avoid occurring idle running in ploughing work, running ridge to show
As；The outer end face of radial direction boss is arc surface, hardly increases resistance during farming, ensures that simple operation, laborsaving,
Farming is efficient；The both sides of radial direction boss are symmetrical arranged side boss, and the outer end face position of the outer end face of side boss and radial direction boss
In on same periphery, the effective width of wheel rim is on the one hand increased to a certain extent in this way, mini-tiller is steady when making farming
Qualitative unaffected, on the other hand, side boss also plays a part of to increase wheel rim and radial direction boss structural strength, to avoid radial convex
Platform is damaged.Steel skeleton is coated in wheel rim, steel skeleton plays liner, to prevent wheel rim from deforming or damage
It is bad, ensure that the service life of wheel rim.Female connector is set on the inner peripheral surface of steel skeleton, which is used for and spoke grafting
Cooperation, in order to which wheel rim is linked into an integrated entity by wheel rim and wheel hub.Reinforcement structure is set on steel skeleton, and reinforcement structure with
Radial direction boss on wheel rim is arranged at intervals, and the structural strength of such wheel rim various pieces can be strengthened, and avoid wheel rim office
Portion's weakness is damaged.Traveling wheel is made of the spoke of rubber wheel rim, steel wheel hub and steel-tube construction, and not only structure is simpler
Single, assembling is easy, at low cost, and support strength is good, durable in the adverse circumstances such as muddy road.
Preferably, the distance between two adjacent radial convex platforms are less than radial direction boss length in the circumferential direction.
In order to further increase earth-grasping force, the outer end face of the radial direction boss is provided with annular knurl.
In order to make the humidification of side boss more notable, the width first gradually increase from outside to inside of the side boss, until leaning on
It is gradually reduced again at nearly wheel rim inner peripheral surface.
Preferably, the width of the wheel rim is 60mm.
In order to simplify structure, making easy to process, it is blockage that the radial direction, which strengthens boss and lateral boss of strengthening,.
The wheel hub is positive six square tube, and spoke is mutually welded with wheel hub.The selection of more than structural hub is convenient, is connect with spoke
Fixing is good, and wheel shaft correspondingly is changed to six square shafts, effectively wheel hub can be avoided to relatively rotate with wheel shaft, good reliability.
Preferably, the number of the spoke is four, which is located at wheel rim radially.
Advantageous effect：The present invention is while rim width is reduced, and by adding radial direction boss and side boss, can reduce
Ground increases earth-grasping force by the region of compaction by rolling, avoids occurring idle running in ploughing work, runs ridge phenomenon, it is ensured that simple operation, province
Power, farming are efficient.In addition, having coated the steel skeleton of liner effect in wheel rim of the present invention, and reinforcement structure is equipped with, to prevent
Wheel rim is deformed or is damaged, and convenient can be connect with spoke.Support strength of the present invention is good, in the adverse circumstances such as muddy road
It is durable.
