[0014] The present invention provides a self-propelled wheeled mechanical rotating anti-sinking device. It has the following beneficial effects: 1. The self-propelled wheeled mechanical rotating anti-sinking device achieves the purpose of synchronization with the rotation direction of the tractor tire by connecting the anti-sinking device to the tractor tire steel rim, and is adjusted by providing driving force through a hydraulic cylinder connected to a hydraulic multi-way valve at the rear of the tractor. The telescopic rod of the hydraulic cylinder is controlled to extend and retract to drive a number of telescopic arms of the anti-sinking device to extend, exceeding the outer diameter of the tire to contact the hard soil layer, and utilizing the earth-moving plate equipped at the front end of the telescopic arm to greatly increase the contact area with the ground, thereby playing an anti-sinking and anti-skid role for the wheeled machinery.

[0015] 2. The self-propelled wheeled mechanical rotating sinkhole preventer can be loaded as a whole on the steel rim of the tractor tire through the arrangement of the wheel axle assembly, and the combination of the link sleeve, the steel rim link plate and the supporting ribs can make the sinkhole preventer firmly fixed on the steel rim of the tractor tire, ensuring that the sinkhole preventer will not loosen or fall off during operation, thereby improving safety and reliability. The use of the supporting ribs can provide additional support and stability to disperse the pressure on the sinkhole preventer, reduce the direct impact on the tire and the steel rim, help protect the tire and the steel rim, and extend their service life. In addition, the use of the steel rim link plate in conjunction with the fixing bolts makes the installation and disassembly of the sinkhole preventer relatively simple and convenient, increases the flexibility of the installation of the sinkhole preventer, and thereby improves the versatility and convenience of the sinkhole preventer.

[0016] 3. The self-propelled wheeled mechanical rotating anti-sinkhole device uses the hydraulic cylinder connected to the tractor's hydraulic multi-way valve to provide driving force for adjustment, which can achieve precise control of the anti-sinkhole device, and the hydraulic cylinder can provide a strong and stable driving force to ensure that the telescopic arm of the anti-sinkhole device can be quickly and effectively extended and retracted, and by controlling the extension and retraction of the telescopic rod of the hydraulic cylinder, the extension degree of the anti-sinkhole device can be flexibly adjusted according to different terrain conditions and work requirements, so that the anti-sinkhole device can adapt to different ground conditions and provide better passability and traction.

[0017] 4. The self-propelled wheeled mechanical rotating anti-sinking device controls several telescopic arms to work synchronously through the driving force of the hydraulic cylinder, ensuring that all telescopic arms can extend and contract in a coordinated manner, providing more uniform support and anti-skid effects. In addition, by utilizing the drive of the hydraulic cylinder, the extension of the telescopic arm can exceed the outer diameter of the tire, so that the anti-sinking device can contact the hard soil layer, thereby providing better support and grip, reducing the sinking and slipping of the tire on soft or slippery ground, improving the passability and traction of the tractor, and enabling the anti-sinking device to adapt to different terrain conditions more quickly, reducing pauses and delays of the tractor during operation, improving work efficiency, and speeding up work progress.

[0018] 5.

The earth-moving plate uses the tractor's own weight to disperse the pressure between the tire and the ground when in use, reducing the pressure on the local terrain and reducing the risk of the tire sinking into soft or unstable ground.

[0019] 6. The self-propelled wheeled mechanical rotating anti-sinking device adopts a fixed cover plate to close the side of the anti-sinking device close to the tire, and uses a second fixing screw to limit the telescopic support arm, thereby providing a certain protection effect, reducing the contact between the tire and sharp objects or debris during use, and thus reducing the risk of tire damage.

[0020] 7. The self-propelled wheeled mechanical rotating anti-sinkhole device, through the coordinated use of the rear fixed plate, the limit plate and the fixed link plate, makes the side of the anti-sinkhole device close to the tire in an unsealed state, thereby reducing the overall weight of the anti-sinkhole device and meeting the tractor's requirements for the passability and lightweight of the anti-sinkhole device. The unsealed state can reduce the accumulation of mud and sand in the anti-sinkhole device, which helps to improve the service life and effect of the anti-sinkhole device. The inner side of the anti-sinkhole device is not sealed, which is convenient for cleaning and maintenance of the anti-sinkhole device and reduces the risk of failure and damage.

Ten support ribs 13 are provided, and the ten support ribs 13 are evenly spaced and distributed on the outer surface of the link sleeve 11. The use of the support ribs 13 provides additional support and stability, disperses the pressure on the anti-sinking device, reduces the direct impact on the tire and the steel ring, and protects the tire and the steel ring. In addition, a disc with the same structure as the steel ring link disk 12 is detachably installed at one end of the link sleeve 11 away from the tire steel ring; The wheel body assembly 2 is used to support the external components.

The hydraulic cylinder 31 provides a strong and stable driving force to ensure that the telescopic arm 33 of the anti-sinking device can be quickly and effectively extended and retracted; Two hydraulic cylinders 31 are provided. By controlling the extension and retraction of the telescopic rod of the hydraulic cylinder 31, the extension degree of the anti-sinking device can be flexibly adjusted according to different terrain conditions and work requirements, so that the anti-sinking device can adapt to different ground conditions. The two hydraulic cylinders 31 are fixedly installed on the outer surface of the front fixed plate 23, and the input end of the hydraulic cylinder 31 is connected to the hydraulic multi-way valve at the rear of the vehicle to provide driving force. The driving force provided by the hydraulic cylinder 31 connected to the hydraulic multi-way valve of the tractor is adjusted to achieve precise control of the anti-sinking device. A second fixing screw 25 is threadedly connected to the outer surface of the front fixing plate 23. The second fixing screws 25 are grouped in pairs, and the number is consistent with the number of telescopic arms 33.

The fixed cover plate 4 is used to close the side of the anti-sinking device close to the tire to protect the vehicle tire.

[0030] The fifth embodiment, based on the first embodiment, the second embodiment and the third embodiment, please refer to Figure 3 , Figure 4 , Figure 5 As shown, the fixing assembly includes a rear fixing plate 5, a limiting plate 6 and a fixed link plate 7, and the fixing assembly composed of the rear fixing plate 5, the limiting plate 6 and the fixed link plate 7 is an unclosed partition-type plate. The rear fixing plate 5 is detachably mounted on the outer surface of one end of the link sleeve 11 by a first fixing screw 24. The number of the rear fixing plates 5 is consistent with the number of the telescopic arms 33. The limiting plate 6 is fixedly mounted on one side surface of the rear fixing plate 5. The outer surface of the limiting plate 6 is movably connected to the outer surface of the telescopic arm 33. The inner wall of one end of the rear fixing plate 5 away from the link sleeve 11 is threadedly connected to the second fixing screw 25. By using the rear fixed plate 5, the limiting plate 6 and the fixed link plate 7, the side of the anti-sinking device close to the tire is in an unsealed state, thereby reducing the overall weight of the anti-sinking device. The fixed link plate 7 is movably mounted on the other side surface of the rear fixed plate 5. The inner walls at both ends of the fixed link plate 7 are threadedly connected to the second fixing screws 25 on the surface of the adjacent rear fixed plate 5. The unsealed state reduces the accumulation of mud and sand in the anti-sinking device, and the telescopic arm 33 is limited and protected by the fit between the limiting plate 6 and the telescopic arm 33 and the fixation of the fixed link plate 7 to prevent the telescopic arm 33 from deflecting and detaching due to excessive pressure.

The limit plate 6 is attached to the outer surface of the telescopic arm 33, and the fixed link plate 7 is fixed by the second fixing screw 25, thereby forming a covering protection for the telescopic arm 33 and the rear fixing plate 5, so that the side of the anti-sinking device close to the tire is in an unsealed state, thereby reducing the accumulation of mud and sand in the anti-sinking device during use.

[0032] The working principle of the self-propelled wheeled mechanical rotating anti-sinking device will be described in detail below.

[0033] When in use, the staff puts the steel rim connecting plate 12 against the steel rim of the tractor tire, and uses the bolts and the threaded slots on the steel rim connecting plate 12 to fix the steel rim connecting plate 12 on the steel rim of the tractor tire. When in use, the tractor's hydraulic multi-way valve is used to provide driving force for the hydraulic cylinder 31 for adjustment. The fixed pin head is driven to extend and retract through the output shaft of the hydraulic cylinder 31, so that the driven plate 32 rotates, the anti-sinking device is precisely controlled, and the telescopic support arms 33 are controlled to work synchronously, so that all telescopic support arms 33 are extended and contracted in unison. The telescopic support arms 33 are extended beyond the outer diameter of the tire to drive the earthmoving plate 34 to extend to increase the contact area with the ground and provide grip. The earthmoving plate 34 cooperates with the earthmoving plate 34 to disperse the pressure between the tire and the ground, reduce the pressure on the local terrain and the contact with the hard soil layer, and reduce the sinking and slipping of the tire on soft or slippery ground, so as to realize the anti-sinking and anti-skid use and application of the tractor.
