Description

Star-shaped ski-proof wheel for walking-tractor

The utility model relates to a kind of agricultural machinery and implement, the walker tractor ski-proof wheel that particularly a kind of process has been improved.

At present, walker tractor (as workers and peasants-12 type) must be equipped with chevron pointing anti sliding wheel band rotovator and just can carry out the paddy field and roll the field operation.This mode of operation efficient is low, and oil consumption is big, and because the rake cutter of rotovator splashes muddy water everywhere in rolling the field operation, to making tractor driver's service conditions quite abominable.

The purpose of this utility model is exactly at above-mentioned shortcoming, and the walker tractor anti sliding wheel is improved, and develops a kind ofly can replace the chevron pointing anti sliding wheel, can replace the walker tractor new-type antiskid wheel of rotovator simultaneously again.

The purpose of this utility model is achieved through the following technical solutions: replace the chevron pointing blade to be welded on abreast between inner steel ring and the outer end steel ring with the L shaped blade that two faceted pebbles are arranged, and the corner angle that make L shaped blade exceed two ends steel ring certain altitude, formation star cage shape garden tubular construction.Two faceted pebbles one wide on the L shaped blade are narrow, and on left anti sliding wheel and right anti sliding wheel, its wide rhombus all (lands earlier when advancing) towards the place ahead, and narrow faceted pebble all (lands earlier when retreating) towards the rear.In order to increase the intensity of L shaped blade, the front end of the wide rhombus certain angle that is upturned.This star anti sliding wheel provides power constantly to roll forward by main frame (walker tractor) during operation in the paddy field, under mechanical self gravitation effect, hand hay cutter advances in the soil and plays anti-skidding effect as the steely melon of L shaped blade, simultaneously L shaped blade constantly produces hand hay cutter, action such as presses, rolls, beats soil in rolling process, make soil breaking play slurry, the weeds rice stubble is rolled have been cut up with a hay cutter and then has been pressed in the mud, ploughs the effect of whole field thereby play to roll, and makes anti sliding wheel have the function of rotovator concurrently.In order to strengthen integral rigidity, be close to inboard, steel ring plane, outer end and be welded with reinforcing pad.This anti sliding wheel diameter is suitably reduced, and L shaped blade quantity suitably reduces, and can replace sheet blade anti sliding wheel and rotovator and use on little walker tractor (as sweet osmanthus board GN-5 type, GN-8 type).

Below in conjunction with accompanying drawing technical solutions of the utility model are further elaborated.

Fig. 1, Fig. 2 are respectively the left and right three-dimensional structure diagram of taking turns of the utility model;

Fig. 3, Fig. 4 are respectively the left and right right elevation of taking turns of the utility model;

Fig. 5 is the utility model blade-side view.

See figures.1.and.2, blade (1) is welded between inner steel ring (2) and the outer end steel ring (3) abreast for the L shaped of two faceted pebbles to be arranged, and makes the corner angle of blade exceed two ends steel ring certain altitude, forms star cage shape garden tubular construction. With reference to Fig. 5, two faceted pebbles one wide of blade (1) are narrow, the wide rhombus front end certain angle that is upturned. With reference to Fig. 1, blade (1) its wide rhombus between the steel ring of two ends is in the same direction; Wheel hub connecting plate (4) is rigidly connected by spoke (5) and inner steel ring (2). Stiffening ring (6) is welded on the inboard, plane of outer end steel ring (3).

The utlity model has simple in structurely, easy to manufacture, with low cost, dependable performance operates steadily, and the characteristics such as easy accessibility have anti-skidding and roll the field dual-use function, can replace the anti-pulley of hand tractor and rotary cultivator to roll the field operation in the paddy field. Its advantage is: 1. energy-efficient. Use the utility model can realize ploughing rake rolling laminated; Owing to cancelled rotary cultivator, hand tractor can use " a fast gear advances " when rolling the field operation, operating speed significantly improves, per hour can roll field 0.4-0.5 hectare, 6.75 kilograms of per hectare oil consumptions, be the 1.5-2 of adapted herringbone anti-pulley band rotary cultivator operating efficiency doubly, the 45-50% of oil consumption. Roll the tilling depth degree and can reach the 120-160 millimeter equally. While has alleviated the load of main frame owing to without rotary cultivator, has got rid of such as the rake cutter to come off, and chain fractures, and damage of bearings often falls into the generation of the most common failures such as car, has greatly improved tractor driver's working environment simultaneously; 2. the utility model anti-pulley lands The Area Ratio herringbone anti-pulley area that lands increases exponentially, thus improved hand tractor anti-ly fall into the car performance and to the span ability (having reduced the destruction to ridge, ditch when namely crossing over) in ridge, ditch; 3. the utility model can overcome the shortcoming that can not move backward when using sheet blade anti-pulley at paddy-field-working when little hand tractor uses. The utility model is applicable to hand tractor and little hand tractor and needs to take advantage of base device to support the use with tail wheel. Installation method of the present utility model has two kinds: 1. upright method of hull section construction: after the wheel hub on the host driven axle and wheelspan adjustment circle are pulled down, wheel hub (formal dress) is installed earlier, two wheelspan adjustment circles (namely adjusting circle outside for two) are installed again, then star-shaped ski-proof wheel are contained on the wheel hub. 2. the anti-method that fills: the wheel hub on the host driven axle is pulled down, on the anti-wheel hub connecting plate that installs to star-shaped ski-proof wheel, installed to together on the driving shaft again, this moment, two wheelspan adjustment circles were in the driving shaft the inside. Must make during installation on the anti-pulley the blade wide rhombus forward, so left and right wheels can not be anti-loaded. Simultaneously, in order to alleviate the stressed degree of driving shaft and bearing thereof, also must be noted that during installation wheelspan is transferred on the minimum position.

A typical example of the present utility model: blade (1) is stamped to form with thick 2-4 millimeter steel plate, long 450-550 millimeter, and the wide 30-50 millimeter of narrow faceted pebble, the wide 60-80 millimeter of wide rhombus, front end upwarps 5-15 degree angle.Also available 3 * 30 * 30 millimeters angle steel are cut into, and a faceted pebble is welded into wide rhombus with the stack pile steel plate, upwarp 5-15 degree angle simultaneously.L shaped blade on revolver and the right wheel respectively is the 10-14 sheet.Inner steel ring (2) and outer end steel ring (3) are made diameter 600-700 millimeter with diameter 16-20 millimeter garden steel.Wheel hub connecting panel (4) and spoke (5) are made with thick 5-8 millimeter steel plate.Reinforcing pad (6) is made with diameter 10-14 millimeter garden steel, and its external diameter is identical with the internal diameter of outer end steel ring (3).With the blade on the star ski-proof wheel left and right wheels of little walker tractor adapted respectively be the 8-12 sheet, the diameter of inner steel ring (2) and outer end steel ring (3) is the 500-600 millimeter.The corner angle of blade (1) exceed two ends steel ring 10-40 millimeter.
