Description

Micro-cultivator walking wheel wheel rim

Technical field

The invention belongs to Miniature tilling implement technical field, specifically, more particularly to a kind of micro-cultivator walking wheel wheel rim.

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.

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 mini-tiller walking Take turns wheel rim.

Technical solution of the present invention is as follows：A kind of micro-cultivator walking wheel wheel rim has rim body, and the rim body is by rubber It is made, it is characterised in that：The width of the rim body is 50-70mm, is evenly distributed on the outer circumference surface of rim body Radial direction boss, the outer end face of the radial direction boss is arc surface, and the center of circle of circumference where radial direction boss outer end face and wheel rim sheet The center of circle of body overlaps, and the both sides in the middle part of the radial direction boss are symmetrically arranged with side boss, the side of the side boss and rim body And radial direction boss is connected as a single entity, the outer end face of side boss and the outer end face of the radial direction boss are located on same periphery, and side is convex The inner face of platform and the inner peripheral surface of the rim body are located on same circumference.

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.

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 rim body inner peripheral surface.

Preferably, the width of the rim body is 60mm.

Advantageous effect：The present invention is ingenious in design, simple in structure, easy to transform, improvement cost is low, is reducing rim width Meanwhile by adding radial direction boss and side boss, ground can be reduced by the region of compaction by rolling, and increase earth-grasping force, avoid ploughing Occur idle running in operation, run ridge phenomenon, it is ensured that simple operation, laborsaving, farming is efficient.

Description of the drawings

Fig. 1 is the structure diagram of the embodiment of the invention.

Fig. 2 is the structure diagram of radial direction boss and side boss.

Specific embodiment

The invention will be further described with reference to the accompanying drawings and examples：

As shown in Figure 1 and Figure 2, the traveling wheel wheel rim of mini-tiller has rim body 1, which is made of rubber. The width of rim body 1 is 50-70mm, and the specific width of the rim body 1 determines that the present embodiment is preferably according to actual needs 60mm.Radial direction boss 11 is evenly distributed on the outer circumference surface of rim body 1, radial direction boss 11 is integrated with rim body 1 Structure, the number of rim body 1 determine according to actual needs, as long as meeting the distance between two adjacent radial convex platforms 11 is less than diameter To the length in the circumferential direction of boss 11.The outer end face of radial direction boss 11 is arc surface, in the outer end face of radial direction boss 11 It is provided with annular knurl, the moulding of annular knurl can be diversified, and the center of circle of circumference and wheel rim where 11 outer end face of radial direction boss The center of circle of ontology 1 overlaps.

As shown in Figure 1 and Figure 2, side boss 12 is symmetrically arranged in the both sides at 11 middle part of radial direction boss, the side boss 12 and wheel The side of rim ontology 1 and radial direction boss 11 are connected as a single entity, and the side boss 12 of the same side is distributed by even circumferential, and side boss 12 Inner end is directed to the axial line of rim body 1.The outer end face of side boss 12 is located at same circumference with the outer end face of radial direction boss 11 On face, the inner face of side boss 12 and the inner peripheral surface of rim body 1 are located on same circumference, and the width of side boss 12 from First gradually increase outside to inside, until being gradually reduced again at 1 inner peripheral surface of rim body.

The preferred embodiment of the present invention described in detail above.It should be appreciated that those of ordinary skill in the art without Creative work is needed according to the present invention can to conceive and makes many modifications and variations.Therefore, all technologies in the art Personnel are available by logical analysis, reasoning, or a limited experiment on the basis of existing technology under this invention's idea Technical solution, all should be in the protection domain being defined in the patent claims.
