Description

Technical Field

[0001] The utility model relates to the technical field of paddy field cultivation, in particular to a wheel for digging ditch in paddy fields. Background Art

[0002] The germination rate and seedling survival rate of direct-seeded rice seeds in paddy fields are key indicators of direct-seeding technology. To improve these rates, furrow seeding is often used. This involves first creating a trench in the plowed and leveled paddy field, then sowing the rice seeds in the trench. The trench also serves as a drainage channel. However, manual trenching is expensive, labor-intensive, and falls short of technical requirements. Therefore, it is necessary to develop a simple trenching machine suitable for direct-seeding rice in paddy fields. Utility Model Content

[0003] The technical problem to be solved by the utility model is to provide a wheel for digging ditch in paddy fields.

[0004] The utility model is realized through the following technical solutions.

[0005] A wheel for digging furrows in paddy fields comprises a wheel hub. Forming discs are provided on both sides of the wheel hub. The diameter of the forming discs is smaller than that of the wheel hub, and the diameter of the forming discs gradually decreases from a side close to the wheel hub to a side away from the wheel hub.

[0006] As a further improvement of the present invention, connecting shafts are provided on both sides of the hub, and the forming disc is sleeved on the connecting shafts.

[0007] As a further improvement of the present invention, the forming disk includes a circular inner disk, a frustum-shaped outer disk, and a sleeve. The circular inner disk is used to fit with the side wall of the wheel hub. The frustum-shaped outer disk is arranged on one side of the circular inner disk. A first connecting hole is provided in the middle of the frustum-shaped outer disk. A second connecting hole aligned with the first connecting hole is provided in the middle of the circular inner disk. The sleeve is arranged between the first connecting hole and the second connecting hole.

[0008] As a further improvement of the present invention, the circular inner disk, the frustum-shaped outer disk and the sleeve are connected to each other by welding.

[0009] As a further improvement of the present invention, a locking cylinder is provided on the connecting shaft, and one side of the locking cylinder abuts against the forming disk so that the circular inner disk fits against the side wall of the hub.

[0010] As a further improvement of the present invention, a locking bolt is provided on the connecting shaft.

[0011] As a further improvement of the present invention, the angle between the generatrix of the frustum-shaped outer disk and its ground radius is 20°-40°.

[0012] As a further improvement of the present invention, a plurality of anti-skid ribs are provided on the wheel hub.

[0013] The beneficial effects of the present invention are as follows: the present invention arranges forming discs on both sides of the wheel hub, and the diameter of the forming discs gradually decreases from the side close to the wheel hub to the side away from the wheel hub. When the wheel is installed on the paddy field operation machinery and equipment and is working, the wheel hub will sink into the paddy field soil due to gravity, and a rut will be formed during driving. The forming discs on both sides are used to widen the rut and make the rut into a V-shaped groove, so that the paddy field operation machinery and equipment can open ditches for sowing and drainage when driving in the paddy field. The structure is simple and the ditching is convenient. BRIEF DESCRIPTION OF THE DRAWINGS
