Description

Technical Field

[0001] This utility model relates to the field of rice transplanter technology, specifically to an anti-sinking mechanism for a rice transplanter. Background Technology

[0002] In mechanized agricultural production, rice transplanters are an important type of agricultural machinery and are widely used in rice planting and other operations. However, when rice transplanters are working in farmland, they often face complex terrain such as loose soil and mud, which can cause the wheels to get stuck in the mud, thus affecting the normal driving and working efficiency of the rice transplanter.

[0003] The shortcomings of existing technology:

[0004] Limited anti-sinking effect: Although some anti-sinking devices can prevent wheels from getting stuck in the mud to a certain extent, they still cannot effectively prevent wheels from slipping or getting stuck when facing deep mud or soft soil. For example, some simple anti-sinking plate designs can increase the contact area on the wheel surface, but their anti-sinking effect is not ideal in complex terrain.

[0005] Lack of flexibility: Most existing anti-sinking devices are fixed structures and cannot be adjusted according to actual operational needs. For example, in dry soil conditions, the anti-sinking device may affect the rice transplanter's travel speed and operating efficiency; while in muddy conditions, it cannot provide sufficient anti-sinking capability.

[0006] Based on the aforementioned shortcomings of the existing technology, we propose an anti-sinking mechanism for rice transplanters to address these shortcomings. Utility Model Content

[0007] To address the shortcomings of existing technologies, this utility model provides an anti-sinking mechanism for rice transplanters.

[0008] To achieve the above objectives, this utility model provides the following technical solution: an anti-sinking mechanism for a rice transplanter, comprising:

[0009] The wheel body is provided with detachable connecting components that are concentric with the wheel body and are distributed in a ring at equal intervals.

[0010] A hollow outer wheel is disposed on the connecting assembly, and a hollow inner wheel slides on the inner wall of the hollow outer wheel. A rotatable annular seat is provided between the outer surfaces of the hollow inner wheel.

[0011] The annular seat is provided with a pushing component that can push the annular seat to move, and the pushing component is provided with a mounting plate that can be detachably installed on the rice transplanter.

[0012] By adopting the above technical solution, after the installation plate is mounted on the rice transplanter, during rice transplanting in paddy fields, the hollow inner wheel on the annular seat is pushed by the pushing component to move and unfold inside the hollow outer wheel. The connection component and the wheel body are used to support the hollow inner wheel and the hollow outer wheel to ensure that they unfold in a combined support state. This allows the hollow inner wheel and the hollow outer wheel to unfold and combine to form a hollow suspended wheel, which increases the overall buoyancy of the wheel, expands the width of the wheel, and increases the contact area with the soil, thus achieving the purpose of preventing sinking. At the same time, combined with the above principle, the hollow inner wheel and the hollow outer wheel can be retracted to reduce the overall contact area with the ground, making it easier for the rice transplanter to travel on hard ground, improving speed and maneuverability.

[0013] As a preferred technical solution of this utility model, the wheel body includes a wheel rim, the inner rim of the wheel rim is provided with a hub, the outer side of the wheel rim is provided with a plurality of annularly distributed traveling teeth, and the outer side of the wheel rim is also provided with a plurality of annularly distributed anti-sinking teeth.

[0014] The anti-trapping tooth is located outside the traveling tooth.

[0015] By adopting the above technical solution, the combination of anti-sinking teeth and walking teeth ensures the anti-sinking effect of the wheel body.

[0016] As a preferred embodiment of this utility model, the connecting component includes:

[0017] A connecting rod, which is connected to the hollow outer wheel;

[0018] Multiple support rods are evenly spaced on the surface of the connecting rod;

[0019] A locking screw is located at the other end of the support link and passes through the hub. The locking screw is externally threaded with a locking nut, which locks the locking screw to the hub.

[0020] By adopting the above technical solution, the connecting components facilitate installation, fixing, and disassembly of the wheel hub, enabling the disassembly and maintenance of the overall structure.

[0021] As a preferred technical solution of this utility model, the hollow outer wheel is provided with a plurality of anti-sinking plates on its exterior, and the hollow inner wheel is provided with a plurality of movable anti-sinking plates located outside the hollow outer wheel.

[0022] Both the anti-sinking plate and the movable anti-sinking plate are flush with the outer surface of the anti-sinking tooth.

[0023] By adopting the above technical solution, the combined anti-sinking effect of the hollow inner wheel and the hollow outer wheel is improved by using anti-sinking plates and movable anti-sinking plates.

[0024] As a preferred embodiment of this utility model, the annular seat has an annular groove on its outer side, and the hollow inner wheel rotates circumferentially within the annular groove without separating from each other.

[0025] By adopting the above technical solution, the annular groove on the annular seat ensures that the hollow inner wheel and the hollow outer wheel will not rotate when the wheel body rotates.

[0026] As a preferred embodiment of this utility model, the hollow inner wheel is provided with a plurality of annular sealing rings on its outer side, and the annular sealing rings are tightly fitted to the inner wall of the hollow outer wheel.

[0027] Using the above technical solution, the annular sealing ring ensures the combined sealing effect of the hollow outer wheel and the hollow inner wheel, preventing water from entering the hollow outer wheel and the hollow inner wheel.

[0028] As a preferred embodiment of this utility model, the pushing component includes a connecting plate and a hydraulic push rod. The connecting plate is detachably disposed on the surface of the annular seat, and the hydraulic push rod is detachably disposed on the surface of the mounting plate. The push rod of the hydraulic push rod is detachably connected to the connecting plate.

[0029] The above technical solution facilitates the installation of the entire equipment on the rice transplanter, and the pusher component facilitates the driving of the hollow inner wheel to move and unfold.

[0030] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0031] 1. The anti-sinking mechanism of this rice transplanter is installed on the transplanter via a mounting plate. During rice transplanting in paddy fields, the hollow inner wheel on the ring seat is pushed by a pushing component to move and unfold inside the hollow outer wheel. The connection component and the wheel body provide support, ensuring that the hollow inner wheel and the hollow outer wheel unfold in a combined support state. This allows the hollow inner wheel and the hollow outer wheel to unfold and combine to form a hollow suspended wheel, increasing the overall buoyancy of the wheel and expanding the overall wheel width, thereby increasing the contact area with the soil and achieving the purpose of preventing sinking. At the same time, based on the above principle, the hollow inner wheel and the hollow outer wheel can be retracted to reduce the overall contact area with the ground, making it easier for the rice transplanter to travel on hard ground and improving speed and maneuverability.

[0032] 2. The anti-sinking mechanism of this rice transplanter has a connecting component that not only provides combined support for the hollow outer wheel and the hollow inner wheel, but also facilitates the disassembly and separation of the connecting component from the wheel body, making it convenient for maintenance of the overall structure.

[0038] 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.

[0039] Please see Figure 1-4 This embodiment provides an anti-sinking mechanism for a rice transplanter, comprising:

[0040] Wheel body 1, with connecting components 2 detachably provided on wheel body 1, which are concentric with wheel body 1 and distributed in a ring at equal intervals;

[0041] A hollow outer wheel 3 is mounted on the connecting assembly 2. A hollow inner wheel 5 is slidably mounted on the inner wall of the hollow outer wheel 3. A rotatable annular seat 7 is provided between the outer surfaces of the hollow inner wheel 5.

[0042] The pusher is provided on the annular seat 7, which can push the annular seat 7 to move. The pusher is provided with a mounting plate 10 that can be detachably installed on the rice transplanter.

[0043] Design of wheel body 1:

[0044] Wheel body 1 is the basic component of the entire anti-sinking mechanism, and it includes:

[0045] Wheel rim 101, with an integrated hub 102 on its inner rim for connection to the drive shaft of the rice transplanter.

[0046] The wheel rim 101 is fixed with multiple annularly distributed walking teeth 103 to improve the wheel's grip on the soil.

[0047] Anti-sinking teeth 104: Multiple ring-shaped anti-sinking teeth 104 are also installed and fixed on the outer side of the wheel rim 101. The anti-sinking teeth 104 are located outside the walking teeth 103, which further increases the contact area between the wheel and the soil and prevents the wheel from sinking into the soft ground.

[0048] Structure of connecting component 2:

[0049] The connecting assembly 2 is used to connect the hollow outer wheel 3 to the wheel body 1, and includes:

[0050] Connecting rod 201, one end of which is fixedly connected to the right side of hollow outer wheel 3.

[0051] Supporting rods 202, multiple supporting rods 202 are connected and fixed at equal intervals on the right side surface of connecting rod 201 to enhance the stability of the connecting assembly.

[0052] The locking screw 203 is installed and fixed at the other end of the support connecting rod 202 and passes through the wheel hub 102. The locking screw 203 is externally threaded with a locking nut 204. The locking screw 203 is locked and fixed on the wheel hub 102 by the locking nut 204, thereby realizing the detachable connection between the connecting component 2 and the wheel body 1. It provides connection support for the hollow outer wheel 3 and facilitates disassembly for maintenance.

[0053] The fit between the hollow outer wheel 3 and the hollow inner wheel 5:

[0054] Multiple anti-sinking plates 4 arranged in an annular pattern and fixed to the outside of the hollow outer wheel 3 are used to increase the contact area between the wheel and the ground. Multiple movable anti-sinking plates 6 arranged in an annular pattern and fixed to the outside of the hollow inner wheel 5 are located outside the hollow outer wheel 3 and are flush with the outer surface of the anti-sinking teeth 104. The hollow inner wheel 5 rotates circumferentially in the annular groove 11 of the annular seat 7 and is tightly fitted with the inner wall of the hollow outer wheel 3 through the annular sealing ring. The hollow outer wheel 3 and the hollow inner wheel 5 are combined to form a hollow suspended wheel with buoyancy, while preventing mud and water from entering the wheel and improving the reliability of the device.

[0055] Structure and function of the pusher component:

[0056] The pushing component is used to move the annular seat 7, thereby adjusting the relative position of the hollow inner wheel 5 and the hollow outer wheel 3, and optimizing the anti-sinking effect. The pushing component includes:

[0057] The connecting plate 8 is detachably mounted and fixed to the left side surface of the annular seat 7 by fastening screws.

[0058] The hydraulic push rod 9 is detachably installed and fixed to the left side surface of the mounting plate 10 by fastening screws. The push rod of the hydraulic push rod 9 is detachably installed and fixed to the connecting plate 8 by fastening screws. By the extension and retraction of the hydraulic push rod 9, the ring seat 7 is pushed to move along the wheel axis, thereby realizing the dynamic adjustment of the anti-sinking plate 4 and the movable anti-sinking plate 6, and controlling the combined width of the hollow outer wheel 3 and the hollow inner wheel 5.

[0059] Working principle:

[0060] Installation and disassembly: The connecting assembly 2 is installed on the wheel body 1 by tightening the locking screw 203 and the locking nut 204, so as to realize the quick connection and disassembly of the hollow outer wheel 3 and the wheel body 1, which facilitates maintenance work.

[0061] Anti-sinking function: When the rice transplanter is traveling in soft or muddy farmland, the hydraulic push rod 9 pushes the annular seat 7 to move, causing the movable anti-sinking plate 6 on the hollow inner wheel 5 to extend outward, so that the hollow inner wheel 5 and the hollow outer wheel 3 unfold and seal, forming a suspended wheel. This increases buoyancy and increases the contact area between the wheel and the ground, dispersing the pressure of the wheel on the ground, thereby preventing the wheel from sinking. The movable anti-sinking plate 6 and the anti-sinking plate 4 unfold together to improve the anti-sinking effect. In addition, the annular groove 11 ensures that the annular seat 7 will not rotate synchronously when the wheel body 1 is driven to rotate. The hollow inner wheel 5 and the hollow outer wheel 3 retract, which makes it easier to reduce the combined width and the resistance to contact with the ground, thereby improving the speed and maneuverability of the rice transplanter.

[0062] Dynamic adjustment: Based on different soil conditions and operational needs, the moving positions of the anti-sinking plate 4 and the movable anti-sinking plate 6 are dynamically adjusted through the extension and retraction of the hydraulic push rod 9 to optimize the anti-sinking effect.

[0063] For sealing and protection, the annular seal between the hollow inner wheel 5 and the hollow outer wheel 3 can effectively prevent mud and moisture from entering the wheel, thus extending the wheel's service life.

[0064] advantage:

[0065] Simple structure and easy installation: The detachable connecting component 2 enables quick installation and removal of the hollow outer wheel 3 and the wheel body 1, facilitating maintenance and replacement.

[0066] Dynamic anti-sinking and highly adaptable: The position of the anti-sinking plate can be dynamically adjusted according to different soil conditions by moving the ring seat 7 through the hydraulic push rod 9, which significantly improves the passability of the rice transplanter in complex terrain.

[0067] With good sealing performance, the annular seal between the hollow inner wheel 5 and the hollow outer wheel 3 can effectively prevent mud and water from entering the wheel, thus improving the reliability and service life of the device.

[0068] With low cost and high efficiency, the anti-sinking mechanism of this application has a compact structure, fewer parts, and low manufacturing cost. At the same time, it can significantly improve the operating efficiency of rice transplanters and has high economic benefits.

[0069] All electrical components mentioned in the text are electrically connected to the main controller and power supply. The main controller can be a conventional and known device such as a computer, and the existing publicly available power connection technology will not be elaborated in the text.

[0070] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
