Description

Technical Field

[0001] This utility model relates to the field of tractor parts technology, and in particular to a retractable tractor anti-rollover counterweight mechanism. Background Technology

[0002] Tractor anti-rollover counterweight mechanism is a set of counterweights installed in specific parts of the tractor. By increasing the overall weight of the tractor and adjusting its center of gravity, it significantly improves the tractor's lateral stability and anti-rollover ability when operating on complex terrain (especially slopes).

[0003] Heavy metal blocks are attached to the front or rear of the tractor to balance the load torque during operation and reduce the risk of rollover due to terrain inclination or uneven load. However, this mechanism has obvious structural defects: First, fixed counterweights increase the overall weight of the tractor, reducing fuel economy and maneuverability; second, the counterweights cannot be dynamically adjusted according to actual working conditions (such as slope and load changes), limiting adaptability and safety; finally, the installation and removal of fixed counterweights is cumbersome and lacks flexibility, increasing maintenance costs and operational difficulty. Summary of the Invention

[0004] The technical problem to be solved by this utility model is that although the traditional fixed counterweight of the tractor can reduce the risk of rollover by balancing the load torque, it has structural defects such as increased overall weight, reduced fuel economy and maneuverability, inability to dynamically adapt to changes in slope and load, and cumbersome installation and disassembly, which increases maintenance costs and operation difficulty.

[0005] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: A retractable tractor anti-rollover counterweight mechanism includes a frame, an adapter plate installed on the top of the frame, a counterweight ring installed near the perimeter of the frame, a counterweight frame provided at the extension positions on both sides of the frame, and a follower box coaxially arranged with the counterweight ring. The adapter plate is used to adapt to the installation of the tractor chassis, and the counterweight ring and follower box are used to adapt to the anti-rollover installation of the tractor wheels. Both ends of the counterweight frame are fitted with telescopic sleeves and external cylinders. The cylinders drive the telescopic sleeves to approach or move away from the counterweight.

[0006] The beneficial effects of this utility model are as follows: As a longitudinal buffer and compensation device, the floating airbag can actively inflate and deflate when the tractor climbs or goes downhill or passes through undulating terrain, causing the load on the front and rear axles to change arithmetically. It can dynamically lift or release the counterweight ring to share the impact load on the axle and help maintain the stability of the ground pressure of the front and rear wheels. The design of core counterweight and adjustable lever arm breaks the drawback of the traditional fixed counterweight which simply increases weight. On flat roads or when transporting light loads, the counterweight can be retracted, which significantly reduces the overall rotational inertia and driving resistance of the tractor, thereby effectively improving fuel economy and improving the maneuverability of steering and driving, achieving a perfect unity of safety and efficiency.

[0007] Furthermore, the frame has a built-in tube sleeve, inside which is a gas storage tank. Extension frames are fixed to both sides of the frame in the direction of the adapter plate. A gas filling pipe and a pressure sensing module are installed on the outer end of the gas storage tank. A bracket for inserting the adapter plate is fixed to the top of the extension frame.

[0008] Furthermore, a protective shell is integrated outside the counterweight ring, and the first roller adapted to the wheel roller and the built-in pressure sensor are distributed and installed on the counterweight ring. A floating air bladder is provided between the counterweight ring and the air storage tank.

[0009] Furthermore, the adapter plate is a semi-circular plate with several sets of mounting slots distributed on it. Several sets of spring columns for connecting to the frame and built-in spring rubber dampers are distributed and fixed at the bottom of the adapter plate.

[0010] Furthermore, a counterweight block is fitted in the middle of the counterweight frame and corner frames are fixed to both sides. A positioning sleeve is fixed to the end of the corner frame away from the counterweight block. A rotating rod is provided in the center of the positioning sleeve. Second rollers are fitted at both ends of the rotating rod. Several sets of anti-collision balls are distributed on the counterweight block. An elastic sleeve is fitted on the outside of the counterweight block.

[0011] Furthermore, a pressure-bearing column is fixedly connected to the bottom of the telescopic sleeve, and shock-absorbing rings are sequentially fitted onto the pressure-bearing column from bottom to top. A plug sleeve is fixedly connected to the bottom of the pressure-bearing column.

[0012] Furthermore, a steering rod is inserted through the center of the rotating box, and a bracket is staggered on the steering rod. The end of the bracket is provided with a side ring that connects to the counterweight ring. A protective sleeve is fitted on the outside of the side ring. A weight module and a connecting ring are sequentially fitted on the steering rod. The weight module has an external sensor light and a built-in pressure sensor and lithium battery pack. Several sets of curved plates are installed in the inner circumference of the outer surface of the rotating box.

[0013] Furthermore, a storage compartment is formed between the two sets of curved plates, with a tension sleeve inside the storage compartment. An anti-pressure ring is fitted on the outside of the rotating box, and a cutting blade is installed on the outside of the curved plate.

[0014] The beneficial effects of adopting the above-mentioned further solutions are: the entire mechanism is standardized and installed through adapter plates, which greatly simplifies the assembly and disassembly process, reduces maintenance costs and time, and at the same time, the detailed design of anti-collision balls, elastic sleeves, cutting blades and tension sleeves effectively prevents collision damage and weed entanglement, ensuring the durability and high reliability of the mechanism in harsh agricultural environments.

Detailed Implementation

[0017] The principles and features of this utility model are described below with reference to the accompanying drawings. The examples given are only for explaining this utility model and are not intended to limit the scope of this utility model.

[0018] In the description of this application, it should be understood that the terms "upper," "lower," "front," "rear," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on this application. In the description of this application, "a plurality of" means two or more, unless otherwise precisely specified.

[0019] Example 1; as Figures 1-5 As shown, it includes a frame 1, an adapter plate 2 installed on the top of the frame 1, a counterweight ring 3 installed near the perimeter of the frame 1, a counterweight frame 4 provided on the extended positions on both sides of the frame 1, and a follower box 502 coaxially arranged with the counterweight ring 3. The adapter plate 2 is used for mounting on the tractor chassis, and the counterweight ring 3 and the rotating box 502 are used for mounting on the tractor wheels to prevent rollover. Both ends of the counterweight frame 4 are fitted with telescopic sleeves 402 and external cylinders 401. The cylinders 401 drive the telescopic sleeves 402 to approach or move away from the counterweight, thereby realizing the dynamic adjustment of the position of the counterweight. The frame 1 has a built-in sleeve 102, and the sleeve 102 has an air tank 104 inside. The frame 1 has extension frames 103 fixed on both sides, close to the adapter plate 2. The air tank 104 has an air filling pipe 101 and a pressure sensing module installed on its outer end. The extension frame 103 has a bracket 105 fixed on its top to insert the adapter plate 2 to enhance overall stability. The counterweight ring 3 has a protective shell 302 integrated on its outer side. The first roller 301 of the adapter wheel roller and the built-in pressure sensor are distributed and installed on the counterweight ring 3. A floating air bag 303 is provided between the counterweight ring 3 and the air tank 104 to buffer and compensate for load changes. The adapter plate 2 is a semi-circular plate with several sets of mounting slots 201 distributed on it. Several sets of spring columns 202 connected to the frame 1 and built-in spring rubber dampers are fixed to the bottom of the adapter plate 2 to absorb vibration and impact. The counterweight frame 4 has a counterweight block in the middle and corner brackets 408 fixed to both sides. The corner brackets 408 are fixed to the end away from the counterweight block with a positioning sleeve 409. The positioning sleeve 409 has a rotating rod in the center, and the two ends of the rotating rod are fitted with second rollers 410. Several sets of anti-collision balls 407 are distributed on the counterweight block. An elastic sleeve 406 is fitted on the outside of the counterweight block to prevent collision damage. The bottom of the telescopic sleeve 402 is fixedly connected to a pressure-bearing column 403, and the pressure-bearing column 403 is fitted with shock-absorbing rings 404 from bottom to top. The bottom of the pressure-bearing column 403 is fixedly connected to a plug sleeve 405 for fixing and transmitting load.

[0020] During operation, when the tractor is traveling on a flat road or carrying a light load, cylinder 401 drives telescopic sleeve 402 to retract the counterweight, reducing the overall weight and moment of inertia, thereby reducing driving resistance and fuel consumption. When the tractor is climbing, descending, or traversing undulating terrain, the pressure sensor inside the counterweight ring 3 (recommended model: MPX5700 series pressure sensor, range 0-700kPa, suitable for agricultural machinery environments) monitors load changes in real time and dynamically adjusts the position of the counterweight ring 3 through floating airbag 303; The floating airbag 303 actively inflates and deflates according to the pressure change of the air tank 104, lifting or releasing the counterweight ring 3 to share the impact load of the axle and help maintain the stability of the ground pressure of the front and rear wheels. The adapter plate 2 is rigidly connected to the tractor chassis through the mounting groove 201. The spring column 202 and the spring rubber damper effectively reduce the vibration caused by uneven road surface and improve driving comfort. The anti-collision ball 407 and elastic sleeve 406 on the counterweight reduce hard impacts in rugged terrain and extend the service life of the mechanism. In terms of materials, the frame 1 and the counterweight are made of high-strength cast iron (such as QT500-7 ductile iron), the adapter plate 2 is made of Q235B carbon steel, and the spring rubber damper is made of a composite material of nitrile rubber and spring steel to ensure durability and fatigue resistance.

[0021] Example 2: Please refer to Figure 1 - Figure 6 Based on Embodiment 1, detailed components of the rotating box 502 are added, including a steering rod passing through the center of the rotating box 502, a bracket 503 with the steering rod interlaced, a side ring 5 at the end of the bracket 503 connected to the counterweight ring 3, a protective sleeve 501 on the outside of the side ring 5, and a weight module 504 and a connecting ring 505 sequentially mounted on the steering rod. The weight module 504 has an external sensor light 508 and a built-in pressure sensor (recommended model: Honeywell MLH series miniature pressure sensor, accuracy ±0.5%FS) and a lithium battery pack (such as 18650 lithium-ion battery pack) to power the sensor light 508 and the sensor. Several sets of curved plates 510 are installed circumferentially on the outer surface of the rotating box 502. A storage compartment 506 is formed between two sets of curved plates 510. The storage compartment 506 has a built-in tensioning sleeve 509. An anti-pressure ring 507 is fitted on the outer side of the rotating box 502. A cutting blade 511 is installed on the curved plate 510 to prevent weeds and soil from getting tangled.

[0022] During operation, the rotating box 502 rotates synchronously with the tractor wheels. The pressure sensor in the weight module 504 monitors the counterweight distribution in real time and provides visual warnings (such as red light indicating high risk) through the sensor light 508. When the system detects uneven load or a tendency to tip over, it automatically adjusts the cylinder 401 and the floating airbag 303 to dynamically optimize the counterweight position. The cutting blade 511 on the curved plate 510 cuts weeds or ropes that may become entangled during rotation. The tensioning sleeve 509 in the storage compartment 506 enhances the structural rigidity of the rotating box 502 to prevent deformation. The anti-pressure ring 507 protects the rotating box 502 from external pressure and extends its service life. In terms of materials, the rotating box 502 and the curved plate 510 are made of aluminum alloy 6061 to reduce weight. The cutting blade 511 is made of high carbon steel (such as T10 tool steel) and is chrome-plated. The tensioning sleeve 509 is made of polyurethane elastomer and the anti-pressure ring 507 is made of nylon 66 composite material to ensure wear resistance and corrosion resistance.

[0023] The working principle described above can be summarized as follows: the mechanism drives the telescopic sleeve 402 through the cylinder 401 to adjust the position of the counterweight, and combined with the dynamic inflation and deflation of the floating airbag 303, it realizes intelligent adjustment of the counterweight. In complex terrain, the system automatically balances the load based on the pressure sensor data to prevent rollover. At the same time, the telescopic design reduces the weight and resistance on flat roads, improving fuel economy and maneuverability. The adapter plate 2 is tightly connected to the tractor chassis, the spring column 202 and the damper provide shock absorption, and the weight module 504 and curved plate 510 of the rotating box 502 further enhance the adaptability and durability of the mechanism, achieving a balance between safety and efficiency.

[0024] Specifically, the mechanism can also integrate tilt sensors (e.g., the SCL3300-D01 tilt sensor with a measurement range of ±30°) for more accurate tractor posture detection, or add wireless communication modules (such as the LoRa module SX1278) to send real-time data to the driver's terminal. In terms of material optimization, the counterweight ring 3 protective shell 302 can be made of ultra-high molecular weight polyethylene (UHMWPE) to enhance wear resistance, and the floating airbag 303 uses neoprene rubber to improve oil resistance. The overall mechanism maintains high reliability and long service life in harsh agricultural environments.

[0025] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
