[0002] With the popularization of mechanized agriculture, various agricultural machines have emerged, enabling farmers to cultivate large tracts of land with minimal human labor and increasing grain production. Most agricultural machines are modeled after automobiles, including a body, wheels, and tillers. Farmers operate the wheels for movement and the tillers for cultivation. However, existing agricultural machinery is only designed for dryland farming. In the south, many crops need to be grown in water, such as lotus roots and water chestnuts. These water-grown crops are still mostly cultivated manually, which is time-consuming and labor-intensive. If existing agricultural machinery were used, the wheels would get stuck in the muddy bottom, making movement difficult.

[0003] In response to this problem, this utility model provides a wheel for agricultural machinery operating on water to solve the aforementioned issues. Utility Model Content

[0034] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0035] like Figures 1 to 4 As shown, this utility model provides a wheel for agricultural machinery operating on water, including a wheel body 1, blades 2, and a connector 3. The wheel body 1 includes a cylindrical wheel core 101 and end plates at both ends of the wheel core 101. The end plates are divided into an inner end plate 102 and an outer end plate 103. The inner end plate 102 is connected to the agricultural machinery. The wheel core 101 is hollow. When the agricultural machinery is on the water, the wheel core 101 and a portion of the two end plates float on the water surface. The blades 2 are located on the outer surface of the wheel core 101. When the wheel body 1 rotates, the blades 2 can stir the water flow and drive the agricultural machinery to move. The connector 3 includes a first connector 301 and a second connector 303. The first connector 301 is located on the agricultural machinery, and the second connector 303 is located on the outer wall of the inner end plate 102. The first connector 301 can be connected to the second connector 303, so that the wheel body 1 is connected to the agricultural machinery.

[0036] Agricultural machinery can range from large tillers and rice transplanters to small, unmanned agricultural machines. The width of wheel 1 extends at least half the width of the vehicle body to ensure the machine doesn't tip over when swaying, increases the contact area between the machine and the water surface, distributes the machine's weight, reduces pressure on the water, and prevents the machine from sinking. The outer surface of wheel 1 can be specially treated to provide anti-slip properties. This special treatment can be achieved through both materials and processes. In terms of materials, special anti-slip rubber materials can be used. This rubber has a high coefficient of friction, and its molecular structure allows for strong interaction with water and other contact materials. It also possesses good flexibility and elasticity, adapting to various deformations of wheel 1 during rotation, while exhibiting excellent wear resistance and water resistance, maintaining stable performance in long-term water-based operations and preventing rapid damage from water erosion and friction. In terms of processes, a thermal spray ceramic coating process can be used. The ceramic material is heated to a molten state and then sprayed at high speed onto the surface of wheel 1, forming a uniform and dense ceramic coating. Ceramic materials are characterized by high hardness and stable chemical properties. The coating surface forms a micro-uneven structure, significantly increasing the roughness of the wheel body 1 surface and thus improving its anti-slip performance. Furthermore, the ceramic coating effectively resists the wear and erosion of mud, sand, and debris in water flow, protecting the wheel body 1 from damage. The connector 3 can be designed for easy installation and removal of the wheel body 1. When the agricultural machinery needs to travel on land, the wheel body 1 can be quickly removed and reinstalled when returning to water operation, greatly enhancing the flexibility and applicability of the agricultural machinery.

[0037] like Figure 1 , 3 As shown, in this embodiment, the first connector 301 includes a first connecting plate, which is fixedly connected to the axle on the agricultural machinery. The first connecting plate has a first connecting hole 304. The second connector 303 includes a connecting rod 305 and a second connecting plate. One end of the connecting rod 305 is fixedly connected to the inner end plate 102, and the other end is connected to the second connecting plate. The second connecting plate has a second connecting hole 306. The end of the first connecting plate away from the agricultural machinery abuts against the end of the second connecting plate away from the connecting rod 305. The first connecting hole 304 and the second connecting hole 306 cooperate with each other and are simultaneously passed through by a first fixing member, so that the first connecting plate and the second connecting plate are fixed to each other.

[0038] When installing wheel 1, align the first connecting hole 304 with the second connecting hole 306, and then secure it using the first fixing component. The first fixing component can be a combination of bolt and nut. The bolt can be directly fixed to the first connecting plate. By rotating wheel 1, the second connecting hole 306 is aligned with the bolt, allowing the bolt to be inserted into the second connecting hole 306, and then secured with the nut. Multiple first connecting holes 304 and second connecting holes 306 can be provided to ensure stability. This design simplifies the connection structure, facilitates the installation and disassembly of wheel 1, and improves the assembly and maintenance efficiency of agricultural machinery water-based operation wheels. The multiple first connecting holes 304 and second connecting holes 306 enhance connection stability and ensure operational safety. Using a combination of bolt and nut as the first fixing component, with the bolt directly fixed to the first connecting plate, and the bolt inserted into the second connecting hole 306 by rotating wheel 1 before being secured with the nut, the operation is convenient and the installation difficulty is reduced.

[0039] like Figure 1 , 5 As shown, in this embodiment, multiple blades 2 are provided, each blade 2 being strip-shaped, with one end of each blade 2 extending from the inner end plate 102 to the outer end plate 103. Each blade 2 is arranged at intervals around the wheel core 101. This arrangement of blades 2 allows the entire wheel to more effectively contact the water during water operations, generating sufficient thrust. The design of multiple strip-shaped blades 2 increases the contact area between the wheel and the water. When the wheel rotates, the blades 2 can paddle like oars, thus propelling the agricultural machinery forward on the water surface. The arrangement at intervals around the wheel core 101 ensures the balance and stability of the wheel during rotation, preventing wheel swaying or deviation from the course due to uneven force. Furthermore, the extension of each blade 2 from the inner end plate 102 to the outer end plate 103 not only enhances the structural strength of the blade 2 itself but also makes the entire wheel structure more stable. During agricultural machinery operations on water, the wheel is subjected to various forces, such as the impact of water flow and the weight of the agricultural machinery itself. This extension design from the inside out better disperses these forces, reducing the risk of damage to the blades 2 due to excessive localized force. At the same time, this design also facilitates the manufacturing and installation of blade 2, reducing production costs and installation difficulty. Blade 2 can be welded to the outside of wheel core 101, or it can be installed in a detachable manner; this embodiment adopts a detachable installation.

[0040] like Figure 2As shown, the wheel core 101 further includes multiple mounting slots 1011 extending from the inner end plate 102 along the wheel core 101 to the outer end plate 103. Each blade 2 can be detachably installed in the mounting slot 1011. The blades 2 can be configured in various specifications, such as blades 2 of different thicknesses and widths. Different specifications of blades 2 can meet the operational needs of agricultural machinery in different water environments. In waters with relatively calm currents, thinner and narrower blades 2 can be selected. These blades 2 are relatively lightweight, reducing resistance during wheel rotation and allowing the agricultural machinery to move more flexibly on the water surface, improving operational efficiency. In waters with rapid currents and large waves, thicker and wider blades 2 can be installed. These blades 2 can withstand greater water flow impact, providing stronger thrust and ensuring stable operation of the agricultural machinery even in harsh environments. Furthermore, the detachable installation of the blades 2 in the mounting slots 1011 greatly facilitates the replacement and maintenance of the blades 2. When blade 2 shows signs of wear or damage during long-term use, operators do not need to replace the entire wheel. They simply need to remove the damaged blade 2 from the mounting slot 1011 and install a new blade 2. This not only saves on maintenance costs but also shortens maintenance time, reducing downtime for agricultural machinery and improving its efficiency. Simultaneously, this design facilitates wheel cleaning and maintenance, allowing for the timely removal of debris and dirt from the blade 2 and mounting slot 1011, ensuring normal wheel operation.

[0041] Furthermore, each blade 2 is provided with a mounting block 201 below it. The mounting block 201 is cylindrical and its length is the same as that of the wheel core 101. The mounting groove 1011 is located on the outer end plate 103 and has a clearance groove 1031 for the mounting block 201 to pass through. The mounting block 201 enters the clearance groove 1031 from the outer end plate 103 until one end of the blade 2 extends from the inner end plate 102 to the outer end plate 103.

[0042] After the mounting block 201 passes through the clearance groove 1031, the mounting block 201 and the mounting groove 1011 cooperate to achieve a stable connection between the blade 2 and the wheel core 101. Since the mounting block 201 is cylindrical and its length is the same as the wheel core 101, the blade 2 can be evenly distributed around the wheel core 101 after installation, ensuring the overall balance and stability of the wheel. During agricultural machinery operation on water, the evenly distributed blades 2 can more effectively convert the force of the water flow into the driving force of the wheel, improving the wheel's propulsion efficiency. Furthermore, the tight fit between the mounting block 201 and the mounting groove 1011 prevents the blade 2 from loosening or wobbling during operation and also prevents water from entering the wheel core 101. Even under conditions of high water flow impact, the blade 2 remains firmly fixed to the wheel core 101, preventing the normal operation of the agricultural machinery from being affected by loose blades 2 and reducing the probability of malfunctions caused by blade 2 issues.

[0043] like Figure 5 As shown, the blade 2 further includes a rotating part 202, a transition part 203, and a fixing part 204. The transition part 203 is located on the long side of the rotating part 202. The end of the transition part 203 away from the rotating part 202 is connected to the mounting block 201. The transition part 203 is used to pass through the clearance groove 1031. The width of the side where the rotating part 202 and the transition part 203 are mounted is larger than the width of the transition part 203, so that the rotating part 202 cannot pass through the clearance groove 1031. The fixing part 204 is located at the position of the rotating part 202. At one end of the outer end plate 103, a fixing part 204 abuts against the outer end plate 103. The fixing part 204 is provided with a first fixing hole 205, and the outer end plate 103 is provided with a second fixing hole 1032. The first fixing hole 205 and the second fixing hole 1032 cooperate with each other, and the second fixing member passes through the first fixing hole 205 and the second fixing hole 1032 at the same time, so that the blade 2 is fixed on the mounting groove 1011. The side of the mounting block 201 connected to the transition part 203 is tightly attached to the inner wall of the wheel core 101.

[0044] During installation, the transition part 203 is first aligned with the clearance groove 1031, allowing the transition part 203 to pass through the clearance groove 1031. Since the width of the side where the rotating part 202 is installed with the transition part 203 is larger than the width of the transition part 203, the rotating part 202 will be blocked outside the clearance groove 1031. At this time, the side of the mounting block 201 connected to the transition part 203 will naturally and tightly adhere to the inner wall of the wheel core 101, providing a stable support base for the installation of the blade 2. Next, the fixing part 204 is abutted against the outer end plate 103, so that the first fixing hole 205 and the second fixing hole 1032 are precisely aligned. Then, a second fastener is used to pass through both the first fixing hole 205 and the second fixing hole 1032 simultaneously, achieving a firm fixation between the blade 2 and the mounting groove 1011. The second fastener can be a screw, and the second fixing hole 1032 is a threaded hole. This fixing method not only makes the blade 2 more securely installed but also facilitates disassembly and replacement. When blade 2 wears or is damaged during use, it can be easily and quickly removed from wheel core 101 for repair or replacement, thus reducing maintenance costs and time. During agricultural machinery operation on water, the unique structural design of blade 2 better adapts to the water flow. Due to its larger width, the rotating part 202 generates greater thrust when rotating in water, improving wheel propulsion efficiency. The transition part 203 connects the rotating part 202 and the mounting block 201, ensuring effective force transmission. Furthermore, since the rotating part 202 cannot pass through the clearance groove 1031, blade 2 is prevented from shifting or falling off during water operation. Simultaneously, the fixing part 204 and the outer end plate 103 are secured by a second fixing member, further enhancing the stability of blade 2. This ensures that blade 2 remains firmly fixed to wheel core 101 even under the influence of water flow impact and centrifugal force generated by wheel rotation, guaranteeing the safety and reliability of the agricultural machinery during water operation.

[0045] To improve the waterproof performance of the wheel core 101, waterproof strips are installed on both sides of the transition section 203, on the side where the mounting block 201 connects to the transition section 203, and at the end of the mounting block 201 located on the outer end plate 103. These waterproof strips are tightly attached to the wheel core 101. These waterproof strips effectively prevent moisture from entering the wheel core 101, preventing corrosion and damage caused by water intrusion, extending the service life of the wheel core 101, and preventing water ingress into the wheel core 1 from increasing the draft of the wheel body 1. Simultaneously, the design of the waterproof strips tightly fitting the wheel core 101 ensures a good sealing effect, minimizing water penetration even in harsh aquatic operating environments.

[0046] Furthermore, the wheel core 101 is provided with a drain port 4, which is connected to the interior of the wheel core 101. A sealing plug 5 is detachably installed on the drain port 4. If water enters the wheel core 101, the sealing plug 5 can be opened, and the water inside the wheel core 101 can flow out from the drain port 4. Then the sealing plug 5 can be closed, and the wheel core 101 can continue to be used.

[0047] The design of the drain outlet 4 and the sealing plug 5 greatly facilitates the maintenance and use of the wheel core 101. In actual water operations, despite the protection of the waterproof strip, a small amount of water may still enter the wheel core 101. The drain outlet 4 allows water to be drained promptly, preventing water accumulation from damaging the internal structure of the wheel core 101. The removable sealing plug 5 ensures both drainage and the sealing of the wheel core 101. During normal operation, the sealing plug 5 tightly seals the drain outlet 4 to prevent water from entering; when drainage is needed, it can be easily opened. Furthermore, the disassembly and installation of the sealing plug 5 are simple. Even at the site of water operations, operators can drive the agricultural machinery back to shore and quickly complete the drainage and sealing process without significantly affecting the normal operation of the machinery. Preferably, the sealing plug 5 is made of rubber. Rubber has good elasticity and sealing properties, allowing it to fit tightly against the drain outlet 4, effectively preventing water leakage. Moreover, the rubber material is water-resistant and corrosion-resistant, and is not easily damaged even in long-term water contact environments, ensuring the service life of the sealing plug 5. In addition, the rubber is soft and will not scratch or damage the drain outlet 4 during disassembly and installation, further protecting the structural integrity of the wheel core 101.

[0048] like Figure 6 As shown, to enhance the sealing effect of the sealing plug 5, annular protrusions or grooves can be provided on the surface of the sealing plug 5. When the sealing plug 5 is installed on the drain outlet 4, these annular protrusions or grooves can form a multi-layer sealing structure with the inner wall of the drain outlet 4, greatly improving the sealing performance. At the same time, waterproof sealant can be applied to the contact surface between the sealing plug 5 and the drain outlet 4 to further enhance the sealing effect and ensure that water will not enter the wheel core 101 from the drain outlet 4 during agricultural machinery water operations.

[0049] like Figure 1-2 , Figure 4As shown, in this embodiment, the wheel core 101 is provided with a lifting component 6. The lifting component 6 includes a lifting connecting part 601 and a lifting part 602. Both the lifting part 602 and the lifting connecting part 601 are rod-shaped. The lifting connecting part 601 is located at both ends of the lifting part 602, and the two lifting connecting parts 601 are connected to the lifting part 602 at an angle. The end of the lifting connecting part 601 away from the lifting part 602 is connected to the wheel core 101, so that when the lifting part 602 is subjected to external force, the lifting component 6 drives the wheel body 1 to move. This design of the lifting component 6 provides great convenience for the installation, disassembly, and transportation of agricultural machinery wheels. In practical applications, when it is necessary to remove the wheel from the agricultural machinery for repair or replacement, the entire wheel body 1 can be lifted steadily by using appropriate lifting equipment or by hand holding the lifting part 602, thereby improving the loading and unloading efficiency of the wheel body 1.
