Abstract

The utility model relates to a mechanical driving wheel for paddy field. The mechanical driving wheel for paddy field is composed of a wheel rim, a wheel hoop, a spoke rib, a supporting ring, a supporting plate, a pin shaft and an anti-skid device, and is characterized in that the pin shaft connects the anti-skid device composed of a shoot plate, tenon teeth and an anti-skid supporting piece to the circumference of the wheel rim so as to force the driving wheel to become a special structure between a chain track and an iron wheel. With the advantages of light weight, and favorable anti-skid function, the utility model is suitable for being used as a driving wheel for walking machines of paddy field.

Description

The paddy field machine driving wheel

The utility model relates to a kind of wheel that is used for the paddy field machine walking, say more more specifically, what relate to is a kind of paddy field machine driving wheel.

At present, the tractor of operation in the paddy field, rice harvester, cultivator, a series of paddy fields such as rotovator walking machine, the wheel that uses on it, the overwhelming majority is an irony, minority be rubber tyre, no matter be rubber tyre, or wheel made of iron, for the above-mentioned walking machine wheel in the paddy field that waits " is not skidded ", do not dally, disadvantage such as do not slide, the spy is designed to projection on the wheel rim circumference of wheel, the shape of projection has " people " font, has plenty of " one " font, the one-tenth that has " ∧ " word, but, more than the driving wheel of three kinds of shapes have following shortcoming: the one, " recessed " on the insufficient height of " protruding " piece, earth are absorbed in around the wheel rim located, and becomes and is not with " protruding ", the circular tire of " recessed ", thereby lost the friction of ground and tire, so wheel " skids ", perhaps be called wheel " idle running ", cultivator in muddy water, grain header can not be walked.

Another shortcoming is that wheel is " idle running " in the original place because wheel " skids " in the paddy field, and walking machine is sunk deeper and deeper mud Tanaka, the mud pit that " idle running " produces is increasing, more and more darker, can not extricate oneself, and resistance increases, not only can not walk, also must the people go to carry away the mud pit; Also having a shortcoming is that power increases, weight is big, make paddy field walking machine weight increase, bulky, this mainly is because resistance is big, can from " mud pit ", pull out in order to make the paddy field walking machine, can overcome resistance and increase power and cause, in addition, another shortcoming, when operation, destroy the soil bottom.

The purpose of this utility model is the weak point at the wheel of the walking machine in the paddy field, overcome its above-mentioned defective, and a kind of paddy field machine driving wheel is provided, be contained on the driving shaft, its feature is after loading onto, wheel can " not skid ", does not produce " idle running ", does not destroy bottom, in light weight, can bring into play the maximal efficiency of power, running resistance is little, is convenient to walk in the mire of paddy field.

For achieving the above object, the utility model adopts following technical scheme:

The utility model paddy field machine driving wheel is by shoe, bearing pin 3, wheel rim 4, rim 5, spoke 6, force-bearing ring 7, force bearing plate 8 are formed, and different with other wheels, its feature is to be evenly equipped with shoe on the circumference of wheel rim 4, can be connected on the wheel rim 4 around the shoe of bearing pin 3 swings.

Described shoe, be made up of anti-skidding load spare 9, boots plate 2, tenon tooth 1, be characterized in being connected with tenon tooth 1 below the two ends of boots plate 2, the top of anti-skidding load spare 9 has circular hole, the diameter of circular hole is greater than the diameter of bearing pin 3, and bearing pin 3 links together shoe and wheel rim 4.

The summary said structure is analyzed, and as seen the utlity model has following advantage: one, antiskid function is arranged; One of its reason is that boots plate 2 contacts with ground, and boots plate 2 is pricked on the earth, and tenon tooth holds on to ground, and wheel can " not skid " because of the influence of muddy mud in advancing, and wheel can " not dally " yet, can walk in the paddy field of very sliding mire; Cultivator, grain header can not fall into in the paddy field yet and go in the mud pit.Two, driving wheel is in light weight, and is big with contact area of ground, is difficult for being absorbed in the dark mud in the running gear of underwater cultivation; This mainly is that paddy field machine driving wheel with shoe is a kind of special construction between chain rail and iron tyre, this shoe can be around bearing pin 3 swings, with respect to wheel rim 4 certain rotation is arranged, as the crawler belt on the tank, with respect to direction relative motion of wheel, boots plate area is done more greatly, and is big with contact area of ground, the paddy field walking machine just can not be absorbed in the dark mud, in being not easy to mire down in mud as tank.

Be further described below in conjunction with drawings and Examples:

Fig. 1 is the front view of paddy field machine driving wheel, and Fig. 2 is an A-A cutaway view on Fig. 1;

Be connected on rim 5 and the force-bearing ring 7 on the wheel rim 4 referring to the spoke 6 on Fig. 1 paddy field machine driving wheel, it bears gravity, supporting wheel rim 4, force bearing plate 8 is connected with force-bearing ring 7, bear the power that force-bearing ring 7 applies, uniform aperture on the force bearing plate 8, be connected with driving shaft, said structure is similar substantially to other normally used iron wheel structures, but the characteristics of paddy field machine driving wheel can be as seen from Figure 1, on wheel rim 4, a shoe is installed every 15 °～30 °, 15 °～30 ° of every rollings of driving wheel just have the boots plate 2 on two shoes or the shoe to contact with ground, shoe also is equivalent to wheel rim 4 and rolls on shoe around bearing pin 3 swings, and described shoe is from Fig. 1, among Fig. 2 as seen, be by boots plate 2, tenon tooth 1, anti-skidding load spare 9 is formed, bearing pin 3 links together shoe and wheel rim 4, because of the diameter of bearing pin 3 less than the circular hole on the anti-skidding load spare 9, shoe can be around bearing pin 3 swings; For the branch that makes shoe have antiskid function to vary, adopt following measures: a kind of is to be connected with tenon tooth 1 below boots plate two ends; For selecting smaller skid resistance, below two ends of boots plate 2, tenon tooth 1 is not set.
