Furthermore, in actual use, the integral welded blade installation method makes blade replacement impossible, resulting in poor expandability. Paddy field wheels are mainly used for paddy field cultivation in mountainous and hilly areas, and their large weight further increases the burden on farmers during the cultivation process, reducing the tillage efficiency and effectiveness of the tiller. There is still considerable room for improvement in the overall design concept and structural construction.

[0004] There is an urgent need to develop a technical solution to address the aforementioned technical problems. Utility Model Content

A mounting hole is opened at the mounting position, and the first hole and the second hole are assembled using mounting holes with different axes.

[0010] Furthermore, both the soil-breaking blade and the leaf plate are equipped with reinforcing ribs.

[0011] Furthermore, the soil-breaking plate is stamped with multiple soil-breaking corners.

[0012] Furthermore, the main shaft is a hexagonal square tube, and multiple mounting discs are welded and fixed to the main shaft at equal intervals; the main shaft is used for drive connection with the output shaft of the tiller.

[0013] Furthermore, the mounting plate is provided with a plurality of mud discharge holes, which are evenly spaced circumferentially with the center of the mounting plate as the axis; furthermore, the outer edge of the mounting plate and the mounting position is bent to form an outward rolled edge, and the inner edge of the mud discharge hole is bent to form an inward rolled edge.

Detailed Implementation

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0016] refer to Figures 1-6 As shown, a paddy field wheel includes a main shaft 1, the main shaft 1 is provided with a plurality of mounting discs 2, and blades 3 are detachably assembled between every two adjacent mounting discs 2; each mounting disc 2 has a plurality of mounting positions 21 for positioning the blades 3, and the blades 3 are provided with a first mounting part 32 and a second mounting part 33; When the blade 3 is assembled on the mounting plate 2, the first mounting part 32 and the second mounting part 33 are respectively connected to the end faces of two adjacent mounting plates 2.

[0017] Specifically, multiple mounting discs 2 are installed in alignment. In this embodiment, the preferred number of mounting discs 2 is three, and the blades 3 are provided with two layers. The adjacent blades 3 on both sides are staggered, and the overall structure is a four-blade double-layer structure with a total of eight blades 3. In actual use, different lengths of main shafts 1 and corresponding numbers of mounting discs 2 can be selected according to the actual terrain and the model of the tiller to adapt to different usage scenarios.

[0018] The basic components of this paddy field wheel include only a main shaft 1, a mounting plate 2, and blades 3. The overall structure is simple, lighter, and stronger. The blades 3 are detachable screw-on assemblies, allowing for batch processing and transportation. This improves transportation efficiency and reduces processing and welding costs during the production and processing stage. In the actual use stage, it enhances the expandability of the blades 3, facilitating subsequent upgrades and replacements, broadening the application scenarios of the paddy field wheel, and extending its service life. The first mounting part 32 and the second mounting part 33 are assembled with the mounting plate 2, simplifying the conventional blade bracing components, reducing welding processes and costs, improving installation efficiency, and reducing the overall processing, transportation, and use costs of the paddy field wheel. It also improves the tillage efficiency of the paddy field wheel.

[0019] This utility model can improve production efficiency and simplify the main components. The components in this embodiment are only: 2*3 mounting plates, 3*8 blades, 1 hexagonal square tube, and 16 bolts. The parts are universal and simple to produce, reducing the number of welding operations and avoiding multiple manual operations.

[0020] In this embodiment, the blade 3 is integrally formed; the first mounting part 32 and the second mounting part 33 are formed by bending the two ends of the blade 31; one side of the blade 31 is bent into a soil-breaking piece 34.

[0021] Specifically, the blade 3 is a one-piece molded structure. The first mounting part 32, the second mounting part 33 and the ground-breaking blade 34 are all formed by stamping and bending, which makes the overall structure lightweight, has high processing efficiency, avoids multiple welding, and reduces processing and turnover costs. Moreover, the one-piece molded structure reduces the number of parts while increasing the structural strength. In this embodiment, the length of the soil-breaking blade 34 is greater than the length of the blade plate 31. When the blade 3 is assembled on the mounting plate 2, the soil-breaking blade 34 is located on the side edge of the mounting position 21. Specifically, the length of the soil-breaking blade 34 is greater than the length of the blade plate 31, so that the soil-breaking blade 34 can completely fit the outer edge of the mounting position 21, which facilitates guidance and positioning during installation and assembly, and can also further improve the strength of the soil-breaking blade 34 during soil breaking and tillage, avoiding damage or loosening of the assembly.

[0022] In this embodiment, the first mounting part 32 is provided with a first hole 35, and the second mounting part 33 is provided with a second hole 36. The axes of the first hole 35 and the second hole 36 do not coincide. A mounting hole 22 is opened at the mounting position 21. The first hole 35 and the second hole 36 are assembled using mounting holes 22 with different axes.

[0023] Specifically, the non-overlapping of the shafts enables a self-locking function, preventing the blades 3 from reversing, deflecting, or loosening due to soil resistance during tillage when they are coaxially fixed. This not only improves the structural strength of the blades 3 but also ensures that each mounting hole is unique. Combined with the bending angle positioning of the bent end of the soil-breaking blade 34, this also ensures that the operator can only install the blades 3 in one direction, achieving a reverse and foolproof design to ensure convenient and efficient use.

[0024] In this embodiment, both the soil-breaking blade 34 and the blade 31 are provided with reinforcing ribs 37; the soil-breaking blade 34 in this embodiment is stamped with multiple soil-breaking corners. Specifically, the reinforcing ribs 37 are stamped protruding ribs; the reinforcing ribs 37 and the soil-breaking corners are stamped together, which improves the overall processing efficiency and structural strength, and reduces the labor and turnover costs of multiple welding operations.

[0025] In this embodiment, the main shaft 1 is a hexagonal tube, and multiple mounting discs 2 are welded and fixed to the main shaft 1 at equal intervals; the main shaft 1 is driven and connected to the output shaft of the tiller. Specifically, the inner diameter of the hexagonal tube is a standard universal size, which is convenient for connecting to the output shaft of tillage machinery such as mini tillers and rotary tillers.

[0026] In this embodiment, the mounting disc 2 is provided with a plurality of mud discharge holes 23, which are evenly spaced circumferentially around the center of the mounting disc 2. Specifically, the mud discharge holes 23 can discharge the soil and mud clods turned up by the blades 3 during the tillage process, preventing soil from accumulating within the rotation range of the blades 3 and improving tillage efficiency; and the mud discharge holes 23 can also reduce the weight of the mounting disc 2.

[0027] In this embodiment, the outer edges of the mounting disc 2 and the mounting position 21 are bent to form an outer rolled edge 24, and the inner edge of the mud discharge hole 23 is bent to form an inner rolled edge 25. Specifically, the outer rolled edge 24 and the inner rolled edge 25 can increase the structural strength of the mounting disc 2, extend the service life of the mounting disc 2, and thus improve the overall tillage efficiency of the paddy field wheel.

[0028] The specific embodiments described herein are merely illustrative examples illustrating the spirit of this utility model. Those skilled in the art to which this utility model pertains may make various modifications or additions to the described specific embodiments or use similar methods to replace them, without departing from the scope defined by the spirit of this utility model.
