Description
Technical field
The invention belongs to the Miniature tilling implement field of agricultural machinery, specifically, more particularly to a kind of walking of mini-tiller
Mechanism.
Background technology
Vigorously supporting and develop with mechanization of agriculture, mini-tiller uses the extensive of increasingly increased.Mini-tiller due to
The features such as in light weight, small volume, simple in construction, behaviour facilitate, it is adapted 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 road wheel of mini-tiller typically uses wide cut rubber wheel, and it is larger with the contact area on ground, easily by ground
Compaction by rolling, it 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 limit utilization rate of the mini-tiller in hillside fields.Some mini-tillers are in road wheel
Excircle on set up ground pawl, although adding earth-grasping force, ground pawl is mostly wedge shape, on the one hand meets the hard thing 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, including steel ring, the wheel hub in steel ring and installed in steel ring
The hinge of periphery, its steel ring are the sheet of annular, if intensity is compared with easily being overloaded after long-term use of causes steel ring to damage；And
The road wheel processing technology of this all-metal construction is complicated, and cost is high, and relative rotation, reliability are also easy to produce between wheel hub and wheel shaft
It is poor.
In addition, the power assembly of mini-tiller is typically arranged in the rear portion of frame, cause complete machine rear bias, when operation
Hand lift handrail is needed to carry out, the labor intensity of operating personnel is big, is also easy to produce fatigue, and is moved after the center of gravity of complete machine, engine,
The reasonability of the arrangements such as speed-changing gear box is poor.
The content of the invention
In view of the drawbacks described above of prior art, the technical problems to be solved by the invention are to provide a kind of mini-tiller walking
Mechanism.
Technical solution of the present invention is as follows：A kind of running mechanism of micro-cultivator, including engine, frame, speed-changing gear box, wheel shaft
And road wheel, it is characterised in that：The engine is located at the middle part of frame, and bottom and the frame of the engine are fixed, engine
Output end and the driving wheel of belt gear connect, the driving wheel of belt gear is in front driven wheel in rear, the belt
The driven pulley of transmission mechanism and the input of speed-changing gear box are connected, and the speed-changing gear box is low early and high after to be obliquely installed, the tooth
The output end of wheel-speed regulating change box and the middle part of wheel shaft connect, and the wheel shaft is centrally located at the underface of engine, the two of wheel shaft
End installation road wheel；
The road wheel includes wheel rim and wheel hub, and wheel rim is made up of rubber, and the width of the wheel rim is 50-70mm, is being taken turns
It is evenly distributed with radial direction boss on the outer circumference surface of rim, the outer face of the radial direction boss is arc surface, and radial direction boss outer end
The center of circle of circumference where face overlaps with the center of circle of wheel rim, and the both sides in the middle part of the radial direction boss are symmetrically arranged with side boss, the side
The side and radial direction boss of boss and wheel rim are connected as a single entity, and the outer face of side boss and the outer face of the radial direction boss are located at together
On one periphery, the inner peripheral surface of the inner face of side boss and the wheel rim is located on same circumference；
The wheel hub is located at the center of wheel rim, and wheel hub is set in axle ends, is provided between wheel hub and wheel rim more
Individual circumferentially equally distributed spoke, the spoke are steel-tube construction, and one end of spoke is mutually fixed with wheel hub, the other end of spoke
It is inserted in female connector, the female connector is in wheel rim.
Engine arrangement is obliquely installed by the present invention in the medium position of frame, and by speed-changing gear box is low early and high after,
Belt gear is set up between engine and speed-changing gear box, so ensure stable drive, it is reliable while, machine gravity
In centre position, on the one hand operate more laborsaving during mini-tiller farming；On the other hand, driving-chain each several part arrangement is easy, assembling behaviour
Make easy.
The wheel rim of the present invention is narrow structure, and width only has 50-70mm, so greatly reduces the contact surface with ground
Product, makes ground small by the region of compaction by rolling, thus effectively reduces the adverse effect to crop root growth.In the excircle of wheel rim
Radial direction boss is uniformly distributed on face, the radial direction boss plays a part of to increase earth-grasping force, to avoid occurring idle running in ploughing work, run
Ridge phenomenon；The outer face of radial direction boss is arc surface, hardly increase farming when resistance, ensure that simple operation,
It is laborsaving, farming efficiency high；The both sides of radial direction boss are symmetrical arranged side boss, and the outer face of side boss and the outer end of radial direction boss
Face is located on same periphery, so on the one hand adds the effective width of wheel rim to a certain extent, mini-tiller when making farming
Stability it is unaffected, on the other hand, side boss also plays a part of to increase wheel rim and radial direction boss structural strength, to avoid footpath
It is damaged to boss.Road wheel is made up of the spoke of rubber wheel rim, steel wheel hub and steel-tube construction, and not only structure is simpler
Single, assembling is easy, and cost is low, and support strength is good, durable in use in the adverse circumstances such as muddy road.
Preferably, the distance between two adjacent radial convex platforms are less than the length of the radial direction boss along the circumferential direction.
In order to further increase earth-grasping force, the outer face of the radial direction boss is provided with annular knurl.
In order that the humidification of side boss is more notable, the width first gradually increase from outside to inside of the side boss, to leaning on
It is gradually reduced again at nearly wheel rim inner peripheral surface.
Preferably, the width of the wheel rim is 60mm.
The wheel hub is positive six square tube, and spoke mutually welds with wheel hub.The selection of above structural hub is convenient, is connected with spoke
Fixing is good, and wheel shaft correspondingly is changed into six square shafts, effectively wheel hub can be avoided to be relatively rotated with wheel shaft, good reliability.
Preferably, the number of the spoke is four, the spoke is located at wheel rim radially.
Preferably, the speed-changing gear box and the angle on ground are 53-58 °.
Beneficial effect：Connection and reasonable arrangement of the present invention, is easily assembled, and machine gravity is placed in the middle, and operation is easier, laborsaving；The present invention
While rim width is reduced, by setting up radial direction boss and side boss, ground can be reduced by the region of compaction by rolling, and increase
Earth-grasping force, avoid occurring idle running in ploughing work, run ridge phenomenon, it is ensured that farming efficiency high；The support strength of road wheel of the present invention
It is good, it is durable in use in the adverse circumstances such as muddy road.
