Abstract

The utility model relates to a rotary tiller iron wheel for leveling a paddy field, which comprises a rim, a spoke, wheel blades and a wheel shaft. A plurality of pairs of wheel blades which are staggered, symmetrical and parallel along the radial direction of the rim are welded outside the rim. The inside of the rim is welded with the wheel shaft through the spoke. The wheel shaft is a hexagonal square tube. The iron wheel is suitable for a rotary tiller to carry out traveling operation in the muddy field without being sunk or slipping, has high leveling efficiency and has simple and light structure. The material cost is saved. The iron wheel is convenient to carry and use. Meanwhile, the hexagonal square tube is used as the wheel shaft, so that the shear stress can be reduced and the service life of a fixing pin for connecting a driving wheel and the wheel shaft is prolonged.

Description

A kind of rotovator iron tyre that is used for the paddy field leveling

Technical field:

The utility model relates to the agricultural tillage field of mechanical technique, especially relates to a kind of rotovator iron tyre that is used for the paddy field leveling.

Background technology:

Along with the science and technology development progress; Agricultural mechanized processes is constantly accelerated; Various agricultural tillage machineries are used widely in agricultural production; Rotovator is a kind of more common tillage machinery; Can be used for the paddy field is turned over, flattened; But its road wheel at paddy-field-working must possess unique structure, and the operation of could in the field of mire, walking smoothly is though various machines working in paddy field road wheels occurred in the prior art; 200710152185.8), " improving the farm machinery iron tyre of structure " (applications/patents number: 95213489.6), " paddy field machine driving wheel " (applications/patents number: 99233220.6), " iron tyre ploughing device " (applications/patents number: 200920279633.5) etc., but these inventions and be not suitable for rotovator and use like " iron wheel structure of farm machinery " (applications/patents number: in the leveling paddy field.Therefore, need badly prior art is improved.

Summary of the invention:

The purpose of the utility model is: a kind of rotovator iron tyre that is used for paddy field leveling is provided, is fit to rotovator walking operation smoothly in the field of mire, improve operating efficiency, simple in structure and low cost of manufacture simultaneously in light weightly is convenient for carrying use.

The technical solution of the utility model is: this iron tyre comprises wheel rim, spoke, wheel blade and wheel shaft; The wheel rim outside weldings have some to along wheel rim diameter to the wheel blade that staggers symmetry and be parallel to each other; Wheel rim inside welds together through spoke and wheel shaft, and wheel shaft is a hexagonal square tube.

The good effect of the utility model is: being fit to rotovator in the walking operation of muddy field and can depression or skid; Leveling efficient is high; And simple in structure light and handy, save material cost, be convenient for carrying use; Adopt the hexagonal square tube as wheel shaft simultaneously, can reduce shear stress, increase the service life of the steady pin that connects driving shaft and wheel shaft.

Description of drawings:

Fig. 1 is the end view of the utility model; Fig. 2 is the three-dimensional view of the utility model.

Wherein: 1, wheel rim, 2, spoke, 3, wheel blade, 4, wheel shaft.

Embodiment:

For the ease of understanding the utility model, provide specific embodiment below in conjunction with description of drawings, the utility model is further set forth explanation.Its effect is understood that it is that the further concrete of the utility model set forth, and is not that the utility model is constituted any type of restriction.That need further statement is the person of ordinary skill in the field, can also make the variation of various ways according to the utility model, all falls into the protection domain of the utility model.

Shown in accompanying drawing, the described iron tyre of the utility model is made up of wheel rim 1, spoke 2, wheel blade 3 and wheel shaft 4, becomes wheel rim 1 with the reinforcing bar Bending Processing earlier; The straight reinforcing bar of several sections equal length of intercepting is as spoke 2; With a hexagonal square steel tube as wheel shaft 4, then wheel rim 1 inner with spoke 2, wheel shaft 4 firm welding, and make the equidistance distribution on wheel shaft 4 of three wheel rims 1; Then get the rectangle steel plate of a suitable size; Two angles on the long limit of one of which are clipped promptly process wheel blade 3, be welded on the outside of wheel rim 1 to wheel blade 3, make that wheel blade 3 is as shown in Figure 1 evenly to distribute along wheel rim 1 is outside; Promptly accomplish a kind of making that is used for the rotovator iron tyre of paddy field leveling, be assembled to and promptly can be used for flattening the paddy field on the rotovator.

Claims

1. one kind is used for the rotovator iron tyre that the paddy field flattens; Comprise wheel rim (1), spoke (2), wheel blade (3) and wheel shaft (4); The outside that it is characterized in that wheel rim (1) is fixedly connected with wheel blade (3), and wheel rim (1) is inner to be fixedly connected with wheel shaft (4) through spoke (2), and described wheel shaft (4) is the hexagonal square tube.
