Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] Reference Figure 1 , Figure 3 and Figure 4This utility model provides an embodiment of an automatic tractor pull adjustment device, comprising a fixed housing 1, a pull mechanism 2 fixedly connected to the top of the outer wall of the fixed housing 1 for automatically adjusting the pull, and connecting mechanisms 3 fixedly connected to the left and right sides of the bottom of the fixed housing 1 for connecting the tractor; the pull mechanism 2 includes a fixed frame 201 fixedly connected to the top of the outer wall of the fixed housing 1, a pull rod 202 rotatably connected to the front side of the inner wall of the fixed frame 201, and connecting frames 203 fixedly connected to the left and right sides of the bottom of the fixed housing 1; the outer wall of the fixed frame 201... An adjusting shell 204 is rotatably connected to the side away from the adjustment shell 204. A drive assembly 205 is fixedly connected to one side of the outer wall of the adjusting shell 204. The drive assembly 205 includes a torque spring 2051, which is fixedly connected to the middle of the inner wall of the adjusting shell 204. A tension tester 2052 is fixedly connected to one side of the outer wall of the torque spring 2051. A hydraulic push rod 2053 is rotatably connected to the left and right sides of the bottom of the adjusting shell 204. The other side of the hydraulic push rod 2053 is rotatably connected to the top of the outer wall of the connecting frame 203. A telescopic rod 2054 is rotatably connected to the front top of the hydraulic push rod 2053.

[0032] Specifically, in this tractor pull automatic adjustment device, the fixed housing 1 is a fixed frame, and its bottom left and right side connecting mechanisms 3 are connected to the tractor to provide installation support. The top pull mechanism 2 is responsible for automatically adjusting the pull. The fixed frame 201 is fixed to the top of the outer wall of the fixed housing 1, and its inner wall front pull rod 202 can be connected to different agricultural implements. When the agricultural implement is working, the adjusting housing 204 adjusts the angle by rotating its connection with the outer wall of the fixed frame 201. The torque spring 2051 in the middle of the inner wall of the adjusting housing 204 generates torque according to the change of pull, and the pull detector 2052 on one side of the outer wall monitors the pull in real time. If the pull needs to be adjusted, the bottom left... The right-side hydraulic push rod 2053 is activated based on detection data. Its other side is rotatably connected to the top of the outer wall of the connecting frame 203. When it extends or retracts, it drives the adjusting shell 204 to rotate, and the top front telescopic rod 2054 extends or retracts accordingly, precisely changing the relative angle between the adjusting shell 204 and the fixed frame 201. The pulling force on the agricultural implement is adjusted through the pull rod 202. When applied to different agricultural implements, the device automatically and precisely adjusts the pulling force according to the load characteristics of the agricultural implement. This is achieved through the elastic buffer of the torque spring 2051, real-time feedback from the tension detector 2052, and the coordinated action of the hydraulic push rod 2053 and the telescopic rod 2054, to meet the needs of different operating scenarios.

[0033] Reference Figure 1 , Figure 2 and Figure 5The connecting mechanism 3 includes a connecting shell 301, which is fixedly connected to the middle left and right sides of the fixed shell 1. A rotating shaft 302 is rotatably connected to the outer wall of the connecting shell 301 on the side away from the center. A clamp spring 303 is fixedly connected to the middle of the inner wall of the rotating shaft 302. A fixing strip 304 is fixedly connected to the top of the outer wall of the rotating shaft 302. An adjusting component 305 is rotatably connected to the bottom front side of the connecting shell 301. The adjusting component 305 includes a fixing plate 3051, which is rotatably connected to the bottom of the outer wall of the connecting shell 301. A connecting plate 3053 is fixedly connected to the middle of the inner wall of the fixing plate 3051. A hydraulic rod 3052 is rotatably connected to the middle of the outer wall of the connecting plate 3053. The hydraulic rod 3052 is rotatably connected to the bottom of the outer wall of the rotating shaft 302. A fixing hook 3054 is slidably connected to the front side of the outer wall of the connecting plate 3053.

[0034] Specifically, the connecting shell 301 is fixed to the left and right sides of the middle of the fixed shell 1, providing stable support for the mechanism. During adjustment, the adjusting component 305 is activated. Its fixing plate 3051 is rotatably connected to the bottom of the outer wall of the connecting shell 301, and the connecting plate 3053 is fixed to the middle of the inner wall of the fixed plate 3051. One end of the hydraulic rod 3052 is rotatably connected to the middle of the outer wall of the connecting plate 3053, and the other end is rotatably connected to the bottom of the outer wall of the rotating shaft 302. The extension and retraction of the hydraulic rod 3052 drives the rotating shaft 302 to rotate around the side of the outer wall of the connecting shell 301 that is away from it. At this time, the clamp spring 303 in the middle of the inner wall of the rotating shaft 302 deforms and generates elastic force to assist the rotating shaft 302 in resetting or maintaining stability. At the same time, the fixing strip 304 at the top of the outer wall of the rotating shaft 302 is adjusted in position as the rotating shaft 302 rotates. In addition, the fixing hook 3054 slidably connected to the front side of the outer wall of the connecting plate 3053 slides to a suitable position after adjustment, which can fix the relevant components and maintain the current state of the mechanism.

[0035] Reference Figure 1 , Figure 2 and Figure 3 A tension gauge 4 is fixedly connected to the bottom of the outer wall of the pull rod 202. A scale line 5 is opened on one side of the outer wall of the tension gauge 4. A connecting block 6 is fixedly connected to the adjacent side of the outer wall of the connecting plate 3053. A lifting ring 7 is rotatably connected to the top of the outer wall of the connecting plate 3053. A fixing clamp 8 is fixedly connected to one side of the outer wall of the telescopic rod 2054. A support plate 9 is rotatably connected to the rear bottom of the hydraulic push rod 2053. A protective plate 10 is fixedly connected to the top of the outer wall of the fixed shell 1. Multiple connecting holes 11 are opened on the top of the outer wall of the protective plate 10.

[0036] Specifically, the pull rod 202 detects the tensile force through the tension gauge 4 fixed to the bottom of its outer wall. The scale line 5 on one side of the outer wall of the tension gauge 4 can intuitively display the tensile force value. The connecting plate 3053 is connected to other components through the connecting block 6 on the adjacent side of its outer wall. The lifting ring 7 rotatably connected to its top can be used to suspend or connect the stressed components. The fixing clamp 8 on one side of the outer wall of the telescopic rod 2054 can fix the test piece or related components. The support plate 9 rotatably connected to the bottom rear side of the hydraulic push rod 2053 can provide stable support and prevent the device from tipping over during the stress process. The protective plate 10 on the top of the fixed shell 1 plays a protective role. The multiple connecting holes 11 on its top facilitate fixed connection with other structures, ensuring the stability and accuracy of the overall device in operations such as tensile force detection.

[0037] Working Principle: In this tractor pull automatic adjustment device, the fixed shell 1 serves as the basic frame. The connecting mechanisms 3 on its bottom left and right sides are used to connect to the tractor, providing installation support for the entire device. The pull mechanism 2 at the top is responsible for automatically adjusting the pull. The fixed frame 201 is fixed to the top of the outer wall of the fixed shell 1. The pull rod 202 on the front of its inner wall can be connected to different agricultural implements. When the agricultural implement is working, the adjusting shell 204 achieves angle adjustment through a rotational connection to the side furthest from the outer wall of the fixed frame 201. The drive assembly 205 plays a core role in this process: the torque spring 2051 in the middle of the inner wall of the fixed frame 201 generates torque according to the change in pull, which, in conjunction with the pull detector 2052 on one side of the outer wall, monitors the pull magnitude in real time. If... When the tension needs to be adjusted, the hydraulic push rods 2053 on the bottom left and right sides will be activated based on the detection data. The other side of the push rod is rotatably connected to the top of the outer wall of the connecting frame 203. When the push rod extends or retracts, it drives the adjusting shell 204 to rotate. At the same time, the telescopic rod 2054 on the top front side extends or retracts accordingly, precisely changing the relative angle between the adjusting shell 204 and the fixed frame 201. Then, the tension on the agricultural implement is adjusted through the pull rod 202. When applied to different agricultural implements, the device can automatically and precisely adjust the tension according to the load characteristics of the agricultural implements. This is achieved through the elastic buffer of the torque spring 2051, the real-time feedback of the tension detector 2052, and the coordinated action of the hydraulic push rod 2053 and the telescopic rod 2054, meeting the needs of different operation scenarios such as plowing, sowing, and harvesting.

[0038] The connecting shell 301 is fixed to the left and right sides of the middle of the fixed shell 1, providing stable support for the entire mechanism. When adjustment is required, the adjusting component 305 comes into play. Its fixing plate 3051 is rotatably connected to the bottom of the outer wall of the connecting shell 301, and the connecting plate 3053 is fixed to the middle of the inner wall of the fixing plate 3051. One end of the hydraulic rod 3052 is rotatably connected to the middle of the outer wall of the connecting plate 3053, and the other end is rotatably connected to the bottom of the outer wall of the rotating shaft 302. When the hydraulic rod 3052 extends or retracts, it drives the rotating shaft 302 to rotate around the connecting shell 305. When the outer wall of housing 301 rotates to the side furthest from it, the clamp spring 303 in the middle of the inner wall of rotating shaft 302 will deform accordingly, generating elastic force to assist rotating shaft 302 in resetting or maintaining a stable state. At the same time, the fixing bar 304 at the top of the outer wall of rotating shaft 302 will also rotate with rotating shaft 302 to achieve position adjustment. In addition, the fixing hook 3054 slidably connected to the front side of the outer wall of connecting plate 3053 can slide to a suitable position after adjustment, which plays the role of fixing related components and maintaining the current state of the mechanism.
