Abstract
The utility model relates to a walking wheel for dry land or paddy field, which is composed of blades with double arch curved surfaces and multiporous handles, a spacing wheel spoke and a hem moving annular plate. The blades with double arch curved surfaces and multiporous handles are evenly distributed and hinged on the circumference of a spacing wheel spoke plate to link the annular plate to be hinged with the handle of each blade. The blades automatically regulate the angles of advancing into and retreating from the soil by the counter force of the soil. The diameter of the walking wheel can be enlarged or reduced by holes on the handles of the blades. The utility model has the characteristics of increasing the traction force, avoiding the sinkage of vehicles, etc., and is suitable for wheeled tractors and wheeled tillers in paddy field for cultivation and walking operation in the dry field and the paddy field.
Description
The utility model provides paddy field, a kind of nonirrigated farmland road wheel, is applicable to wheel-tire tractor and wheeled underwater cultivation machine, ploughs whole nonirrigated farmland and paddy field walking operation.
Wheel-tire tractor and wheeled underwater cultivation machine have employed rubber tire, iron tyre, cog wheel now, though with their characteristics separately respectively in the walking operation of nonirrigated farmland and paddy field, produce the original place of advancing and trackslip also unavoidably, falling back digs pit falls into the car accident.Though engine has enough power to make the road wheel rotation, can not make complete machine from transfering to pitfall.Must take other measures to get rid of.
Produce the reason of above-mentioned accident, can not return study carefully in load too big because there is enough power to make road wheel rotation.Can not return and study carefully in positive pressure too smallly,, sizable positive pressure be arranged because road wheel rotation pushes away away earth in a large number and dug out pitfall.Under the enough prerequisite of power and positive pressure, the reason that produces above-mentioned accident is and rubber tire tooth, iron tyre blade, inserted number, penetrating angle, geometric configuration, relevant with the soft or hard of effective area of contact of earth and wheel footpath size and earth.
The purpose of this utility model will provide paddy field, a kind of nonirrigated farmland road wheel exactly, and it can effectively improve tractive force, reaches the effect that positive and negative car is not digged pit.
The purpose of this utility model is achieved in that
The road wheel that it is become by blade part, spoke portion, interlock ring flat-plate.Its structure takes to improve uniform being hinged on the wheel former circumference of the two arching blades of porous handle of tractive force, and each porous blade can be by the desirable penetrating angle rotational positioning that moves forward and backward on spoke, with each blade handle of interlock ring flat-plate hinge connection.Its principle be utilize the wheel former after forward-reverse begins to rotate in a flash, the blade in the earth drives the interlock ring flat-plate by the counter-force of earth and rotates, the interlock ring flat-plate makes whole blades realize that automatically regulatings advance and retreat desirable penetrating angle simultaneously.And utilize the porous handle to regulate amplification and dwindle the road wheel diameter, with nonirrigated farmland and the paddy field that adapts to different depth soft or hards.
Below by executing example, in conjunction with the accompanying drawings the utility model is further described.
Fig. 1 is the utility model concrete structure and fundamental diagram;
Fig. 2 is blade part figure;
Fig. 3 is the blade-side view;
Fig. 4 is an A-A cutaway view among Fig. 1.
Principle of work of the present utility model, as Fig. 1, shown in Figure 4, when wheel shaft (1) drive former (2) marches forward is the moment that the arrow hand of rotation begins to rotate, and the blade in the earth (3), (4), (5) drive interlock ring flat-plate (6) centering rotation under centering block (7) effect by the counter-force of earth.The whole blade rotation that to cut with scissors connection simultaneously desirable penetrating angle retaining nails (8) that is positioned to advance has then obtained the advance desirable penetrating angle of whole blades when rotating of road wheel.In like manner, drawing back when wheel shaft (1) driven wheel former (2) is the arrow backward rotation, then obtains the desirable penetrating angle that road wheel retreats whole blades when rotating.Thereby realized that the whole blades of automatically regulating advance and the desirable penetrating angle that retreats respectively, improved the situation of existing rubber tire tooth, iron tyre blade, inserted unidirectional fixed forward penetrating angle.Because positive and negative car (promptly moving forward and backward), the equal desirable penetrating angle of its blade, and also blade construction is to improve tractive force, so can obtain positive and negative effect of not digging pit, can obtain to improve the effect of tractive force again.
This road wheel blade takes down structure to match with road wheel integral body to reach to improve tractive force:
Lobe numbers: the number of blade adopts the 6-8 sheet, and present embodiment is 8, lacks than traditional road wheel blade.Because blade is few, earth is not cut into fritter, the earth volume that is cut is big, is difficult to be pushed away away by blade, just can obtain big counter-force, can obtain big tractive force.
The blade penetrating angle: as shown in Figure 1, its penetrating angle is that the interior value of 22 ° of-24 ° of scopes of angle of blade longitudinal plane of symmetry and road wheel diameter is desirable, and present embodiment is 22.5 °.When blade tip and axle center are in the vertical ground state, this blade obtains maximum positive voltage power, again near the earth hardcore, then can obtain tractive force limit, and this moment, the resultant direction of blade application force, not only directed towards ground but also little with the ground angle, therefore both be difficult for pushing away away earth, can have obtained tractive force limit again, thereby avoided the situation of easily trackslipping.
The geometric configuration of blade: show as Fig. 2, Fig. 3, adopt two arching face rectangles of the thin thick middle in edge.It is characterized in that curved surface decomposes diffusion layer by layer step by step to earth, more and more littler, thereby more difficult being pushed away away by blade of earth digged pit, blade can obtain big counter-force, promptly obtain big tractive force, this architectural feature has been improved the rubber tire profile of tooth, the conventional iron impeller blade, and inserted structure is with the situation of force localization on small size earth.The blade handle adopts the porous handle, and it is scalable or dwindle the road wheel diameter to select for use different holes to be hinged on former (2) and the connection ring flat-plate (6), with nonirrigated farmland and the paddy field that adapts to different depth soft or hards.
The payload space that blade contacts with earth: because of the upper limb of two arching blades is thin, especially during paddy-field-working, blade whenever takes a step forward, and receives the wedge shape footprint hole of compressing earth before this and producing blade in earth.Blade tip obtains counter-force at that time, is that rotate when advancing in the center of circle with the wedged hole tip, because the upper limb of blade is thin, its front does not also contact or when having only slight contact wedged hole front to be resistance area, blade has left wedged hole.From then on show that this pair of arching face blade reduced this running resistance in earth of blade, then reduced consumption of power.And the back of blade, the counter-force that obtains earth because of need promptly obtains tractive force, is that wedged hole back earth is close in compression comprehensively, helps improving very much tractive force.Therefore, this pair of arching face blade can be widened area as required in the horizontal direction, and the power that can will reduce to consume is converted into tractive force, thereby has improved the power utilization rate, has improved tractive force than traditional blades.
