Description

Efficient Paddy Wheel

technical field

The utility model relates to a paddy field farming machine part, in particular to a paddy field plowing wheel of a miniature tillage machine.

Background technique

At present, the paddy field cultivating wheel of general miniature cultivator is made up of front and rear support rings, blade and connecting shaft. A reinforcement plate is connected between the front end of the connecting shaft and the front support ring, and the middle support ring is divided into a tiller area between the front support ring and the rear support ring, and blades are distributed on the circumference of each tiller area, and the adjacent tiller The blades of the zone are misaligned in the axial direction. During work, because the blades are in line contact with the ground, when the field is relatively hard, there is no function of breaking the soil and leveling, and the efficiency is low; at the same time, the strength of the blades is not enough, it is easy to deform and break, and the service life is short; and in leveling paddy fields In the process, the effect of farming is not ideal because of the small buoyancy.

Utility model content

The technical problem to be solved by the utility model is to provide a paddy field wheel with the function of breaking ground and high farming efficiency.

The technical scheme of the utility model is as follows: a high-efficiency paddy field wheel, including a front support ring, a middle support ring, a rear support ring, blades, a connecting shaft and a connecting bar, and the centers of the front support ring, the middle support ring and the rear support ring are respectively Connected on the same connecting shaft through the connecting strips in the rings, between the two supporting rings is the blade area, and blades are distributed on the circumference of each blade area, and the blades of the adjacent blade areas are axially staggered. The feature is that: the outer ends of the blades are bent in the same direction at 120°-180°, and the outer surfaces of the outer ends of the blades are provided with soil-breaking nails. When cultivating the dry and hard fields, the soil-breaking nail has a good function of breaking the soil, which can greatly improve the farming efficiency.

The above-mentioned soil-breaking nail is formed by bending an iron sheet to form a triangular convex nail. The two bottom edges of the triangular convex nail are welded to the blade, and the other top edge protrudes outwards, and the protrusion is close to the outer end of the blade. The soil-breaking nail with this structure is more conducive to breaking the soil.

A notch adapted to the support ring is formed at the inner end of the blade, and the support ring is located in the notch and welded to the blade.

A reinforcement block is welded between the inner surface of the outer end of the blade and the support ring. The blades are not easy to bend and deform.

The angle between the blades on the support ring and the tangent line at the weld of the support ring is 60°-170°.

Beneficial effects: the utility model has the function of breaking the soil while cultivating, improving the cultivating efficiency; the strength of the blade is increased, it is not easy to deform and break, and the service life is improved; and in the process of leveling the paddy field, the greater buoyancy makes the effect of farming more good.

Detailed ways

Below in conjunction with accompanying drawing and embodiment the utility model is further described:

As shown in Figure 1, Figure 2, and Figure 3, the high-efficiency paddy field wheel consists of a front support ring 1, a middle support ring 2, a rear support ring 3, blades 4, connecting shafts 5, connecting bars 6 and blades 4, the front The centers of support ring 1, middle support ring 2 and rear support ring 3 are respectively connected to the same connecting shaft 5 through connecting strips 6 in the rings. There are blades 4, and four blades 4 are arranged in one blade area, and the blades 4 in the adjacent blade area are axially staggered. It is welded with blade 4 inside. The outer ends of the blades 4 are bent in the same direction at 120°-180°, and the included angle between the blades 4 on the support ring and the tangent line at the welding position of the support ring is 60°-170°. A reinforcing block 8 is welded between the inner surface of the outer end of the blade 4 and the supporting ring. The blades are not easy to bend and deform. The outer surface of the outer end of the blade 4 is provided with a soil-breaking nail 7. The soil-breaking nail 7 is bent by an iron sheet to form a triangular convex nail. The two bottom edges of the triangular convex nail are welded to the blade 4, and the other top edge protrudes outward. , the protrusion leans on the blade 4 outer ends. The soil-breaking nail with this structure is more conducive to breaking the soil. When cultivating the dry and hard fields, the soil-breaking nail has a good function of breaking the soil, which can greatly improve the farming efficiency.
