A type of integrated paddy field wheel assembly for mowing and breaking soil.

Abstract

This utility model provides an integrated paddy field wheel assembly for weeding and soil breaking, comprising: an axle connected to the drive structure of a rotary tiller; at least two discs fixedly installed along the length of the axle on the outside; and a soil breaking and weeding mechanism fixedly welded to the outside of two adjacent discs along the circumferential direction and staggered. Four evenly spaced support sections are integrally formed on the surface of the discs along the circumferential direction. The soil breaking and weeding mechanism includes V-shaped blades, a weeding section, and multiple soil breaking blades. In use, the wavy weeding section and soil breaking blades work together to complete weeding and soil breaking in one operation, improving the efficiency of paddy field preparation. The weight-reducing holes and rib structure reduce weight while ensuring strength, thus reducing energy consumption. The V-shaped blades are stamped and reinforced with welding for wear resistance, and the hexagonal axle prevents slippage, making it suitable for long-term high-load operation and highly durable. The staggered blades agitate the mud and water more thoroughly, resulting in uniform mud mixing, which is beneficial for subsequent transplanting or sowing.

Description

Technical Field

[0001] This utility model relates to the field of agricultural machinery technology, and in particular to an integrated paddy field wheel assembly for mowing and breaking soil. Background Technology

[0002] In rice paddies, tilling is an important task that loosens the topsoil, optimizes soil structure, and promotes soil health. The effect is to increase production and income. Paddy field wheels are the wheels on a micro-tiller or tractor that travels in paddy fields.

[0003] Chinese Patent Application No. 202023079342.7 discloses a paddy field wheel with anti-weed entanglement, including a support structure, axle, and blades. The support structure includes a support plate with a protrusion fixed to its side. The support plate has sludge passage holes, and the protrusion is fixed at at least one location: the edge of the sludge passage hole or the edge of the support plate. Multiple connecting parts are provided along the edge of the support plate, and the blades are connected to these connecting parts. The axle is fixed to the support plate. This application effectively solves the problem of high welding workload and low production efficiency in paddy field wheels. However, the sludge passage holes on the support plate reduce the strength of the plate material next to the holes. After prolonged use, adjacent holes are prone to deformation and breakage, affecting service life. Furthermore, the blades have smooth edges, resulting in poor weed control. Utility Model Content

[0004] In view of the shortcomings of the prior art described above, the purpose of this utility model is to provide an integrated paddy field wheel assembly for weeding and soil breaking, which solves the problems that the blade mounting disc of the paddy field wheel is prone to breakage and deformation after long-term use, and that the blade edges are smooth, resulting in poor weeding effect and affecting later use.

[0005] To achieve the above and other related objectives, this utility model provides an integrated paddy field weeding and soil-breaking wheel assembly, comprising: an axle connected to a rotary tiller drive structure; at least two discs fixedly installed along the length direction on the outside of the axle; and a soil-breaking and weeding mechanism fixedly welded to the outside of two adjacent discs along the circumferential direction and staggered. Four evenly spaced support portions are integrally formed on the surface of each disc along the circumferential direction. The soil-breaking and weeding mechanism includes V-shaped blades welded and covering the outside of the support portions, wavy weeding portions opened at the V-shaped blade openings, and multiple soil-breaking blades evenly spaced along the length direction and welded to the outside of the V-shaped blades. The axle is rigidly connected to the rotary tiller drive structure via a hexagonal cross-section, transmitting power to the discs and the soil-breaking and weeding mechanism. The discs drive the V-shaped blades to rotate, and the wavy weeding portions at their openings cut paddy field weeds through serrated edges, achieving efficient weed control. The soil-breaking blades welded to the outer side of the V-shaped blades cut into the soil as they rotate, and the spiked protrusions further break up the soil clods. At the same time, the blades push the mud and water to mix, forming a soft mud layer. The staggered V-shaped blades reduce drag, the weight-reducing holes on the wheel reduce inertial loss, while the large and small annular ribs and radial ribs enhance the rigidity of the wheel, support the stress on the blades, and extend their service life.

[0006] Preferably, the longitudinal section of the axle is hexagonal.

[0007] Preferably, the side of the wheel has four weight-reducing holes evenly spaced around the wheel axle.

[0008] Preferably, the end of the soil-breaking blade is integrally provided with multiple spiky protrusions.

[0009] Preferably, both sides of the wheel are provided with concentric large ring ribs and small ring ribs, and multiple radial ribs are provided between the large ring ribs and small ring ribs, with each radial rib distributed between two adjacent weight reduction holes.

[0010] Preferably, the end of the radial rib extends to the surface of the support portion.

[0011] Preferably, the V-shaped blades are formed by stamping, and adjacent V-shaped blades are staggered.

[0012] As described above, the integrated paddy field wheel assembly for mowing and breaking soil disclosed in this utility model has the following beneficial effects: 1. This utility model improves the efficiency of paddy field preparation by setting up a wavy mowing section and a soil breaking blade to work together to complete weeding and soil breaking in one go.

[0013] 2. This utility model reduces weight and energy consumption while ensuring strength through lightweight design, weight-reducing holes and rib structures.

[0014] 3. This utility model features wear-resistant design with V-shaped blades formed by stamping and welding reinforcement, and hexagonal wheel axle to prevent slippage. It is suitable for long-term high-load operation and has strong durability.

[0015] 4. This utility model uses staggered blades to stir the mud and water more thoroughly, resulting in a more uniform mud mixture, which is beneficial for subsequent transplanting or sowing.

[0016] 5. This utility model adapts to various weed and soil conditions by setting spiky protrusions and wavy blades, and is especially suitable for deep paddy fields or areas with dense weeds.

[0017] Therefore, this utility model effectively overcomes the various shortcomings of the prior art and has high industrial application value. Attached Figure Description

[0027] In one embodiment, refer to Figure 1 The wheel 2 has four weight-reducing holes 21 evenly spaced around the axle 1 on its side. The multiple weight-reducing holes 21 can reduce weight and energy consumption.

[0028] In one embodiment, refer to Figure 1 The end of the soil-breaking blade 33 is integrally provided with multiple spike-like protrusions 331. The spike-like protrusions 331 help to further break up soil clods, while the blade pushes the mud and water to mix, forming a soft mud layer.

[0029] In one embodiment, refer to Figure 1 Both sides of the wheel 2 are provided with concentric large ring ribs 5 and small ring ribs 6, and multiple radial ribs 7 are provided between the large ring ribs 5 and small ring ribs 6.

Driven by the power unit of the rotary tiller, the axle 1 is rigidly connected to the drive structure of the rotary tiller, transmitting power to the disc 2 and the soil breaking and mowing mechanism 3. The disc 2 drives the V-shaped blades 31 to rotate. The wavy mowing part 32 at the opening cuts paddy field weeds through the serrated edge, achieving efficient weeding. The soil breaking blades 33 welded to the outside of the V-shaped blades 31 cut into the soil as they rotate. The thorn-like protrusions 331 further break up the soil clods. At the same time, the blades push the mud and water to mix, forming a soft mud layer. The staggered V-shaped blades 31 reduce resistance, the weight reduction holes 21 reduce inertial loss, and the concentrically arranged large ring ribs 5, small ring ribs 6 and radial ribs 7 can enhance the rigidity of the disc 2. The support part 4 disperses the force on the blades and extends their service life.
