[0022] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

This is merely for the convenience of description and does not indicate or imply that the device or element must have a specific orientation, be constructed and operated in a specific orientation. Therefore, it cannot be understood as a limitation on the present invention.

[0024] In addition, it should be noted that in the description of the present invention, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For those skilled in the art, the specific meanings of the above terms in the present invention can be understood according to the specific circumstances.

[0025] like Figures 2 to 5 As shown together, a tractor includes a vehicle ladder 1 connected to a tractor body 2, the vehicle ladder 1 includes a rigid structure ladder 10 and a flexible structure ladder 11, the rigid structure ladder 10 is connected to the tractor body 2; the rigid structure ladder 10 includes at least one rigid step 100; the flexible connection ladder includes a flexible step 110, the flexible step 110 includes a rigid frame 1100 and a soft layer 1101 wrapped outside the rigid frame 1100, and the rigid frame 1100 is connected to the last rigid step 100 of the rigid structure ladder 10 through a connecting assembly. In this embodiment, the rigid structure ladder 10 includes two rigid steps 100, and the flexible structure ladder 11 may include two or more flexible steps 110. Of course, the number of rigid steps 100 and flexible steps 110 depends on the actual structural configuration of the tractor.

[0026] Because the ladder 1 of the utility model has a flexible structure ladder 11, the tractor ladder 1 has better adaptability and flexibility; the flexible structure ladder 11 can adjust the distance between the last step of the ladder 1 and the ground, thereby solving the stability problem under uneven ground or special circumstances; at the same time, the flexible structure ladder 11 can also reduce the vibration and noise between the ladder 1 and the tractor body 2, and improve the driver's comfort and work efficiency; the structure of the flexible step 110 makes the ladder 1 have better anti-slip performance and durability, and further improves its safety and reliability; the tractor is expected to be widely used and promoted in the field of agricultural machinery; and the utility model has the advantages of simple structure and easy implementation.

[0027] like Figure 4 and Figure 5 As shown, the rigid skeleton 1100 of the utility model includes a footrest portion and two connecting portions respectively arranged at both ends of the footrest portion, and the footrest portion and the two connecting portions are connected to form a U-shape; in a preferred embodiment, the footrest portion and the two connecting portions are arranged as an integral structure.

[0028] The rigid skeleton 1100 may be made of, but not limited to, steel wire, and the soft layer 1101 may be made of, but not limited to, polyurethane material. The flexible step of this structure has both sufficient rigidity to ensure the reliability of the connection and flexibility.

[0029] Specifically, the rigid frame 1100 is pre-punched into a U-shape, and then the rigid frame 1100 is wrapped with rubber, i.e., polyurethane material, and the hardness of the rubber can be controlled at 70 Shores, so that the last step of the ladder 1 maintains a U-shaped structure, which is convenient for the driver to get on the vehicle. The last step of the ladder 1 is a U-shaped structure, which can control the elongation of the last step of the ladder 1 to not exceed 30% when bearing the weight of the 180KG driver getting on the vehicle, ensuring the comfort of the driver getting on the vehicle without feeling of stepping on air; it can also ensure that when the tractor is running at a speed of more than 20KM / h, when encountering an obstacle, it can produce more than 90% deformation to avoid the obstacle.

[0030] By introducing the U-shaped rigid frame 1100 and the polyurethane material, the tractor ladder 1 has better adaptability, durability and safety, solves the problems existing in the structure of the traditional ladder 1, and is expected to be widely used and promoted in the field of agricultural machinery.

[0031] like Figure 5 As shown, each rigid step 100 of the rigid structure ladder 10 in the utility model includes a pedal 1001 and two connecting plates 1000 respectively arranged at both ends of the pedal 1001; the pedal 1001 and the two connecting plates 1000 can be welded together; in a preferred embodiment, fixed plates 1102 are respectively arranged at both ends of the rigid frame 1100.

[0032] In this embodiment, the connection assembly includes bolts 3 and a pressing plate 4, that is, the flexible step 110 and the last rigid step 100 of the rigid structure ladder 10 are connected by bolts 3, and the bolts 3 pass through the pressing plate 4, the fixing plate 1102 and the connecting plate 1000 on the same side in sequence to achieve a fixed connection between the rigid frame 1100 and the rigid step 100. The provision of the fixing plate 1102 and the pressing plate 4 increases the reliability of the connection.

[0033] Specifically, the rigid frame 1100 is welded to the fixed plate 1102, and after welding, it is coated with plastic to form an integrated structure. One or more mounting bolt holes are opened on the fixed plate 1102. During the coating, the bolt holes are not coated with plastic. During the installation process, the plastic-coated fixed plate 1102 is pressed by a pressure plate 4, and is fixed to the connecting plate 1000 of the rigid step 100 by bolts 3. The connecting plate 1000 is provided with bolt holes for fixing the fixed plate 1102.

[0034] like Figures 2 to 5 As shown together, the tractor boarding ladder 1 in the utility model is divided into three levels, the first two levels adopt the traditional rigid structure ladder 10, and the last level adopts the flexible structure ladder 11, that is, the last step is a flexible step 110, and the flexible step 110 has good toughness.

[0035] Specifically, the last flexible step 110 uses a flexible material to wrap the rigid frame 1100 structure, wherein the characteristics of the flexible material enable the last flexible step 110 to bend or elastically deform when the driver gets on or off the vehicle, thereby reducing the effective height between the boarding ladder 1 and the ground. In addition, the flexible step 110 is connected to the steel pedal 1001 of the rigid structure ladder 10 through structures such as bolts and a pressure plate 4, thereby ensuring the stability and safety of the entire boarding ladder 1.

[0036] The setting of the flexible structure ladder 11 makes the tractor boarding ladder 1 of the utility model have better adaptability and flexibility. When the driver gets on and off the vehicle, it can operate more easily and conveniently without facing the height limitation and instability problems of the traditional rigid structure boarding ladder 1. In addition, when encountering obstacles, the flexible connection design can also enable the boarding ladder 1 to flexibly avoid them, further improving the safety and operability of the driver.

[0037] The flexible structure ladder 11 in the utility model not only improves the operability and safety of the vehicle ladder 1, but also effectively prolongs the service life of the vehicle ladder 1; the structural setting of the flexible step 110 makes it have the functions of corrosion resistance and good toughness, thereby reducing the occurrence of rust and deformation of the vehicle ladder 1.

[0038] To sum up, the flexible structural ladder 11 in the utility model has good toughness, corrosion resistance and durability. Good toughness is one of the important factors to ensure the service life of the tractor boarding ladder 1; flexible materials with good toughness are selected so that the boarding ladder 1 can maintain its original shape and performance when subjected to bending and deformation when the driver gets on and off the vehicle, and is not prone to fatigue damage; good corrosion resistance. In the farmland environment, the boarding ladder 1 is often exposed to a humid and dusty environment and is easily corroded by moisture and chemicals. Therefore, it is necessary to select materials with good corrosion resistance to ensure that the boarding ladder 1 can be used for a long time without damage; good durability also improves the service life of the boarding ladder 1; after repeated bending and torsion, the flexible connecting material must be able to maintain its performance and function, and is not prone to fatigue damage or breakage.

[0039] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications made within the spirit and principle of the present invention, improvements to the same tractor, etc., should be included in the protection scope of the present invention.
