Description

Technical Field

[0001] This utility model relates to the field of paddy field wheel technology, and in particular to a three-five-six-bladed straight plate high-efficiency paddy field wheel. Background Technology

[0002] The paddy field wheel is the most commonly used tillage component of a tiller. Engine power drives the rotary tiller shaft to rotate via a transmission device. The power-driven rotary blades continuously cut the soil, throwing the cut soil clods backward to collide with the mudguard and leveling plate, further breaking up the soil before it falls to the ground. This achieves the purposes of cutting, throwing, breaking up, and leveling the soil, with the reaction force of the soil propelling the tiller forward. During tillage, the operator can adjust the pressure on the handlebars according to the tillage conditions, regulate the tillage depth using the resistance bar, and maintain the tiller's balance and forward speed. However, existing paddy field wheels on tillers have smooth blade surfaces, which cannot effectively excavate silt when the tiller cuts the soil, thus failing to achieve better tillage results.

[0003] A search revealed that prior art CN210900240U discloses a paddy field wheel for a miniature tiller. This wheel includes several annular positioning wheels mounted on its mounting shaft. Several blade-shaped tillers are evenly arranged circumferentially between adjacent annular positioning wheels. The outer edges of each tiller protrude beyond the annular positioning wheels, and one side of the blade's side is concave while the other side is convex, forming a bucket-like structure. This novel paddy field wheel allows the tiller to effectively excavate silt when cutting soil, resulting in better plowing performance.

[0004] However, when the applicant used the aforementioned paddy field wheel, he found that the annular positioning wheels on both sides of the existing paddy field wheel had a smooth contact structure with the silt, which made it easy to slip. Furthermore, the blades and bucket-shaped structure were easily entangled by aquatic plants and other factors, which was not conducive to the stable operation of the paddy field wheel. Utility Model Content

[0005] The purpose of this invention is to provide a three-, five-, or six-bladed straight-plate high-efficiency paddy field wheel that can reduce the wheel from being entangled in aquatic plants and improve its working stability.

[0006] To achieve the above objectives, this utility model provides a three-five-six-blade straight plate high-efficiency paddy field wheel, including a hexagonal tube. Toothed connecting and fixing discs are welded to both sides of the hexagonal tube, and connecting plates are welded between the toothed connecting and fixing discs. Three connecting plates are evenly spaced in a ring, and six vertical soil-breaking grass-breaking blocks are welded to each connecting plate at a single interval. The hexagonal tube is also welded with multiple blade holders, and the blade holders are equipped with six irregularly shaped blade supports via connectors, which do not interfere with the vertical soil-breaking and grass-crushing blocks.

[0007] Among them, a reinforcing fixing plate is welded and fixed between the connecting plates. The reinforcing fixing plate is sleeved and installed on the outside of the hexagonal tube, and is welded and fixed to the three connecting plates respectively, and is located in the middle of the connecting plates.

[0008] The connecting component can be a T-shaped screw and nut structure or a rivet structure.

[0009] One of the toothed connecting fixing plates is also welded with a crawling plate on one side.

[0010] The crawling board is arranged in a ring with four evenly spaced sections and has a stepped structure.

[0011] This utility model discloses a three-, five-, or six-bladed straight-plate high-efficiency paddy field wheel. By welding and installing toothed connecting and fixing discs on both sides of a hexagonal tube, the toothed connecting and fixing discs are less prone to slippage compared to the smooth annular positioning wheel in contact with silt in existing technologies. Furthermore, the multiple vertical soil-breaking and grass-chopping blocks and irregularly shaped blade holders enable the cutting of aquatic plants during wheel rotation, preventing the wheel from becoming entangled in aquatic plants and thus reducing the wheel's entanglement and improving operational stability.

[0019] The embodiments of the present invention are described in detail below. Examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, but should not be construed as limiting the present invention.

[0020] like Figures 1 to 5 As shown, where Figure 1 This is a schematic diagram of the overall structure of a three-, five-, or six-bladed straight-plate high-efficiency paddy field paddlewheel. Figure 2 This is a structural diagram of the crawling board. Figure 3 This is a structural diagram of the toothed connecting fixing disc. Figure 4 This is a structural diagram of a reinforced fixing plate. Figure 5 This is a schematic diagram of the irregularly shaped blade holder. This utility model provides a three-, five-, or six-blade straight-plate high-efficiency paddy field reel: including a hexagonal tube 101, a toothed connecting and fixing disc 102, a connecting plate 103, a vertical soil-breaking and grass-chopping block 104, a blade holder 105, a connecting piece 106, and an irregularly shaped blade holder 107. The aforementioned solution can reduce the reel's entanglement with aquatic plants and improve its working stability. It is understood that the aforementioned solution can improve the working stability of the paddy field reel.

[0021] In this embodiment, the hexagonal tube 101 is hollow inside, which facilitates its installation in conjunction with the drive shaft.

[0022] The hexagonal tube 101 has toothed connecting and fixing discs 102 welded on both sides, and connecting plates 103 are welded between the toothed connecting and fixing discs 102. Three connecting plates 103 are evenly spaced in a ring, and six vertical grass-breaking blocks 104 are welded on each connecting plate 103 at intervals. The rotating toothed structure of the toothed connecting and fixing discs 102 can improve the anti-slip performance when the paddy field wheel rotates. The six vertical grass-breaking blocks 104 are welded on each connecting plate 103. The six vertical grass-breaking blocks 104 can cut the aquatic plants when the paddy field wheel rotates to avoid tangling. The six vertical grass-breaking blocks 104 are all provided with blade structures to facilitate cutting the aquatic plants when rotating.

[0023] Multiple blade holders 105 are welded onto the hexagonal tube 101. Six irregularly shaped blade supports 107 are mounted on each blade holder 105 via connectors 106, and these blade supports 107 do not interfere with the vertical soil-breaking and grass-chopping block 104. Rectangular slots are provided on the blade holders 105 to facilitate the sliding insertion of the mounting parts of the irregularly shaped blade supports 107. Alignment through holes are provided on both the blade holders 105 and the irregularly shaped blade supports 107 to facilitate the installation of the connectors 106.

[0024] Secondly, reinforcing fixing discs 108 are welded and fixed between the connecting plates 103. The reinforcing fixing discs 108 are sleeved on the outside of the hexagonal tube 101 and welded and fixed to the three connecting plates 103 respectively, and are located in the middle of the connecting plates 103. Each reinforcing fixing disc 108 has three slots for easy sliding and locking onto the connecting plates 103, and after welding and fixing, it can further improve the overall strength of the paddy field wheel.

[0025] Then, the connector 106 can adopt a T-shaped screw and nut structure or a rivet structure. When the connector 106 adopts a T-shaped screw and nut structure, the irregular tool holder 107 is easy to disassemble. When the connector 106 adopts a rivet structure, the installation stability of the irregular tool holder 107 is better, and subsequent disassembly can be carried out by simply grinding off the rivet head.

[0026] Furthermore, a crawler plate 109 is welded to one side of one of the toothed connecting fixing discs 102. The crawler plate 109 can further form an anti-slip structure when the paddy field wheel rotates, further improving the working stability of the paddy field wheel.

[0027] Finally, four crawler plates 109 are evenly spaced in a ring, and each plate has a stepped structure 110. The stepped structure 110 facilitates the discharge of mud splashed during rotation.

[0028] When using this utility model to reduce the entanglement of paddy field wheels with aquatic plants and improve working stability, this application welds and installs the toothed connecting fixing plate 102 on both sides of the hexagonal tube 101. The rotating toothed structure of the toothed connecting fixing plate 102 can improve the anti-slip performance of the paddy field wheel during rotation. Six vertical soil-breaking and grass-breaking blocks 104 are welded to each connecting plate 103. When the paddy field wheel rotates, the six vertical soil-breaking and grass-breaking blocks 104 can cut the aquatic plants with their blade-like structure, avoiding entanglement. The toothed connecting fixing plate 102 is smoother than the existing technology when the paddy field wheel rotates. The structure of the annular positioning wheel in contact with the silt makes it less prone to slippage, thus greatly ensuring the stability of the paddy field wheel during rotation. Furthermore, the multiple vertical soil-breaking and grass-chopping blocks 104 and the irregularly shaped blade holder 107 can cut aquatic plants when the paddy field wheel rotates, preventing the paddy field wheel from getting tangled. Welding and fixing the reinforcing fixing plate 108 can further improve the overall strength of the paddy field wheel. The crawling plate 109 can further form an anti-slip structure when the paddy field wheel rotates, further improving the working stability of the paddy field wheel, thereby reducing the paddy field wheel from getting tangled in aquatic plants and improving working stability.

[0029] The above-disclosed embodiments are merely one or more preferred embodiments of this application and should not be construed as limiting the scope of this application. Those skilled in the art can understand that all or part of the processes for implementing the above embodiments and equivalent changes made in accordance with the claims of this application still fall within the scope of this application.
