During farmland operations, tractor operators often need to work outdoors for a long time, exposed to direct sunlight, rain and strong winds. The working environment is relatively harsh. In the design of tractors, awnings are a common accessory. Their main function is to provide shade and protection for drivers and machines. Awnings can prevent direct sunlight, reduce driver fatigue, and also protect machines from bad weather.

[0003] Existing tractor sunshades usually use integrated iron parts, and the sunshade effect is achieved by extending iron sheets from the top of the iron column. The sunshade awning is usually installed by welding on the tractor frame for one-time use.

The outer walls of the two groups of support frames 3 are provided with limit grooves 8. There are several groups of limit grooves 8, and the number can be changed according to actual needs. They are used to fix the height of the awning with multiple clamping limit blocks 15. The inner and outer walls of the two groups of support legs 2 are respectively fixedly connected with extension rods 6 and extension sleeves 7. The extension rods 6 and extension sleeves 7 are used to assist the extension of the awning to prevent the deformation and distortion of the support frame 3 due to wind resistance or external force. The outer wall of the extension awning 4 is slidably connected to the inner wall of the extension frame 5, and the outer wall of the extension rod 6 is slidably connected to the inner wall of the extension sleeve 7. The bottom end of the outer wall of the support leg 2 is slidably connected to the inner wall of the welding seat 1, and the outer wall of the support frame 3 is slidably connected to the inner wall of the support leg 2.

[0032] Reference Figure 1-Figure 3 The fixing component includes a follower ring 10, which is used to assist the return spring 11 to maintain a stationary state to prevent the return spring 11 from being deformed and twisted due to the rotation of the card block 12. The follower ring 10 is elastically connected to the inner wall of the outer surface of the welding seat 1 through the return spring 11, and the outer wall of the follower ring 10 is slidably connected with a card block 12. The end of the card block 12 is provided with an inclined surface. When installing the awning, the supporting leg 2 can be squeezed and then clamped and fixed, and there is no need to manually release the limit and then install it. The outer wall of the follower ring 10 is slidably connected to the inner wall of the eaves of the card block 12, and the outer wall of the card block 12 passes through and is slidably connected to the inner wall of the welding seat 1. The end of the card block 12 is clamped on the inner wall of the card slot 9. One end of the return spring 11 is fixedly connected to the inner wall of the outer surface of the welding seat 1, and the other end of the return spring 11 is fixedly connected to the outer wall surface of the follower ring 10. Through the opposing extrusion force between the return spring 11 and the follower ring 10, the card block 12 is always clamped on the inner wall of the card slot 9 without being affected by external force.

[0033] Reference Figure 2-Figure 4The limiting assembly includes an auxiliary ring 13, the outer wall of the auxiliary ring 13 is slidably connected to the inner wall of the outer surface of the supporting leg 2, the auxiliary ring 13 is elastically connected to the limiting block 15 through a limiting spring 14, the limiting block 15 is provided with a circular cross-section, which is used to more stably engage the limiting groove 8, and the friction force is greater than that of the cylindrical contact surface. The end of the outer wall of the limiting block 15 is engaged with the inner wall of the limiting groove 8, and the outer wall of the limiting block 15 passes through and is slidably connected to the inner wall of the supporting leg 2. One end of the limiting spring 14 is fixedly connected to the outer wall of the auxiliary ring 13, and the other end of the limiting spring 14 is fixedly connected to the lower surface of the eaves of the limiting block 15. Through the opposing extrusion force between the limiting spring 14 and the auxiliary ring 13, the limiting block 15 is always engaged with the inner wall of the limiting groove 8 without being affected by external force.

[0034] Working principle: When installing and adjusting the width and height of the awning, manually pull the limit block 15 out of the limit groove 8 to release the limit, then manually lift the support frame 3 to drive the extension awning 4 and the extension frame 5 to the required height, and then freely adjust the distance between the extension awning 4 and the extension frame 5 according to the width of the tractor frame, so as to adapt to tractors of different widths and seat heights, block direct sunlight for the driver, reduce the driver's fatigue caused by long-term driving, and provide a comfortable operating environment for the driver.

[0035] When installing and disassembling the awning, the limit is released by manually pulling the block 12 out of the slot 9, and then the block 12 is rotated to be engaged with the inner wall of the welding seat 1, freeing the hand operating the limit operation, and then the awning as a whole can be separated from the welding seat 1. During installation, the supporting legs 2 are placed into the welding seat 1 and the inclined surface of the block 12 is squeezed and moved backward. The rear supporting legs 2 drop to the bottom of the welding seat 1, and the block 12 is rebounded into the slot 9 by the reset spring 11 to be engaged and fixed, so that the awning can be quickly disassembled and assembled, which is convenient for use under different climatic conditions, and can also be used as a roll cage to avoid rollover caused by bumpy terrain, thereby ensuring the safety of the operator to a certain extent.
