Description

Technical Field

[0001] This utility model relates to the technical field of agricultural tires, specifically to agricultural tires that are puncture-resistant and cut-resistant. Background Technology

[0002] Agricultural tires refer to pneumatic rubber tires specifically designed for agricultural machinery and vehicles. Their design, structure, and performance are optimized for the complex working conditions in farmland. These tires typically have the following technical characteristics: deep and wide tread patterns to increase the contact area with the ground and reduce contact pressure, thereby reducing sinking and slipping in soft or wet soil.

[0003] Modern agricultural tires have wide and deep treads for anti-skid purposes, but these treads are also extremely prone to embedding stones and pebbles. If the tire continues to be used, the stones can easily pierce the tire and cause damage. Utility Model Content

[0004] The purpose of this invention is to provide an agricultural tire that is puncture-resistant and cut-resistant, in order to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an agricultural tire resistant to punctures and cuts, comprising a tire body, a groove, and an outer rod. The outer surface of the tire body is provided with a groove, and the interior of the tire body is provided with a connecting groove. The inner wall of the connecting groove is fixed with an outer rod, and the inner wall of the tire body is provided with a limiting groove.

[0006] When using the puncture-resistant and cut-resistant agricultural tires in this technical solution, the hydraulic cylinder can drive the hydraulic rod to move, the hydraulic rod can drive the push plate to move, the push plate can drive the protective pad to move, and the push plate can push out stones or pebbles stuck inside the groove, preventing stones or pebbles from getting stuck on the inner wall of the groove and causing the tire body to be punctured. The protective pad can protect the groove and reduce the probability of the groove being punctured.

[0007] Preferably, the inner wall of the tire body is provided with a fixing groove, and a wear-resistant layer is fixed to the inner wall of the fixing groove. The wear-resistant layer is in direct contact with the airflow in the tire cavity and any impurities and moisture that may be present. It can effectively resist the abrasion and corrosion of the inner rubber layer by long-term inflation-deflation cycles and the volatilization of agricultural fertilizers and chemical agents, and significantly extend the overall service life of the tire.

[0008] Preferably, the inner wall of the wear-resistant layer is embedded and fixed with an inner tube, and the inner tube has an installation groove inside. The outer wall of the inner tube and the wear-resistant layer form an embedded fit, and the inner wall of the inner tube is further fitted with the rim or support ring through the installation groove, realizing radial and axial dual limiting, which significantly reduces the risk of slippage and rolling of the inner tube relative to the outer tire during high torque and low air pressure operations.

[0009] Preferably, the outer rod has a support groove inside, and an inner rod is slidably connected to the inner wall of the support groove. The inner rod slides in the support groove, which can adjust the effective support length in real time according to the undulation of the farmland and changes in load, maintain the stability of the tire cross-section height, reduce tire deformation caused by overload or impact, and improve the smoothness of operation and passability.

[0010] Preferably, a push plate is fixed to the upper surface of the inner rod, and a protective pad is installed on the upper surface of the push plate. The protective pad is made of a highly elastic, tear-resistant material, which can absorb and dissipate the instantaneous impact kinetic energy when the machinery crosses field ridges or rocks.

[0011] Preferably, a hydraulic cylinder is installed on the inner wall of the support groove, and a hydraulic rod is movably inserted into the upper surface of the hydraulic cylinder, the hydraulic rod being connected to the inner rod. The hydraulic cylinder-hydraulic rod system can achieve stepless, rapid, and precise control of the extension length of the inner rod by adjusting the oil pressure according to the hardness of the working ground, the weight of the equipment, and the magnitude of the instantaneous impact, ensuring that the tire section height and ground pressure are always within the optimal range, reducing the probability of soil compaction and slippage.

[0012] Preferably, the inner wall of the limiting groove is fixed with a fixing layer, and the outer surface of the limiting groove is fixed with a connecting layer. The fixing layer and the inner wall of the limiting groove form a rigid interface with high bonding strength, ensuring that key components (such as hydraulic cylinders, guide sleeves, etc.) are stably supported in both the axial and radial directions; the connecting layer achieves secondary consolidation with the external structure (such as the outer rod or the tire carcass), forming a double locking mechanism that significantly suppresses fretting wear and loosening failure under impact loads.

[0013] Compared with the prior art, the beneficial effects of this utility model are: 1. This utility model, by setting up a hydraulic cylinder, a push plate, and a protective pad, achieves the effect of preventing stones and pebbles from getting stuck in the inner wall of the groove and causing the tire body to be punctured. The hydraulic cylinder can drive the hydraulic rod to move, the hydraulic rod can drive the push plate to move, the push plate can drive the protective pad to move, and the push plate can push out the stones or pebbles stuck in the groove, preventing stones and pebbles from getting stuck in the inner wall of the groove and causing the tire body to be punctured. The protective pad can protect the groove and reduce the probability of the groove being punctured.

[0014] 2. This utility model achieves the effect of extending the service life of the tire body by setting a wear-resistant layer, a fixing layer, and a connecting layer. The inner cavity of the tire body is sequentially arranged with a fixing groove, a wear-resistant layer, an inner tube, and a mounting groove, forming a four-level nesting from the outside to the inside. The interfaces of each layer are tightly fitted, which not only retains the necessary flexibility of the tire body to absorb the impact of the ground, but also improves the radial stiffness through the composite constraint of the wear-resistant layer and the inner tube, achieving a combination of rigidity and flexibility, reducing rolling resistance and energy consumption. The fixing layer in the limiting groove accurately positions the internal components (such as hydraulic cylinders and support rods), and the outer connecting layer is then fixed to the tire body skeleton for a second time. The inner and outer double-layer limiting structure can effectively resist shear slippage under high torque and low air pressure conditions, avoid interlayer peeling or bolt loosening, and extend the service life.
