A second motor is fixedly connected to the upper right side of the hull, and a lead screw is fixedly connected to the end of the motor's main shaft. The lead screw is helically connected to the lower slider. Turning on the second motor rotates the lead screw, causing the lower slider to rotate and slide in the lower slide rail. The slider drives the second rod to move, and the mutual rotation of the second rod makes the horizontal plate rise and fall stably. This device can quickly change the center of gravity of the loading device, thereby quickly obtaining multiple sets of test data. This device is conducive to obtaining more realistic data that conforms to the actual situation. However, in actual use, there are still the following shortcomings: From a practical point of view, during the experiment, the height of the front wheel cannot be adjusted, which makes it inconvenient to adjust the height according to different test sites, reducing its practicality.

[0021] The present invention will be further described below with reference to the embodiments.

[0022] Please see Figure 1-4 This utility model provides a tractor traction test loading device, including a hull 1, a counterweight frame 2 and a suspension frame 3. The counterweight frame 2 is fixedly installed on the top of the hull 1. The suspension frame 3 is connected to the hull 1. A buffer mechanism 4 is provided at the connection between the suspension frame 3 and the hull 1 for buffer support. An adjustment mechanism 5 is provided on the right side of the hull 1. A plow 6 is installed at the bottom of the hull 1. A rear wheel 7 is fixedly connected to the left side of the bottom of the hull 1.

[0023] Further as Figure 2 , Figure 3 and Figure 4As shown, it is worth noting that the buffer mechanism 4 includes a damping buffer 401 and a connecting block 402. The damping buffer 401 is hinged to the upper part of the hull 1 and connected to the suspension frame 3. The connecting block 402 is connected to the suspension frame 3. A connecting frame 403 is provided on the outer side of the connecting block 402. A matching groove 404 is opened on the inner side of the connecting frame 403 corresponding to the connecting block 402. A first spring 405 is fixedly connected to the bottom of the connecting block 402 and fixedly installed in the groove 404. A fixed shaft 406 is hinged to the bottom of the connecting frame 403. A connecting seat 407 is fixedly connected to the outer side of the fixed shaft 406. The connecting seat 407 is connected to the left side of the hull 1. There are two damping buffers 401. The two damping buffers 401 are respectively located on the upper part of the hull 1 and connected to the suspension frame 3. There are two connecting blocks 402 on the suspension frame 3. The two connecting blocks 402 are symmetrically located at both ends of the bottom of the suspension frame 3.

[0024] In use, the damping buffer 401 is set so that the vibration of the hull 1 is buffered and transmitted to the suspension frame 3, thereby reducing its vibration effect. At the same time, the connecting block 402 slides in the slide groove 404, and the first spring 405 provides buffering support, thereby achieving its vibration buffering effect. This reduces the vibration transmission of the hull 1 and the suspension frame 3 to the tractor, thereby improving its stability.

[0025] Further as Figure 2 and Figure 3 As shown, it is worth noting that there are two rear wheels 7 at the bottom of the hull 1. The two rear wheels 7 are symmetrically arranged at the bottom of the hull 1. A fixing frame 701 is provided at the connection between the upper part of the rear wheel 7 and the hull 1. An installation groove 702 is opened on the upper part of the fixing frame 701. A limit plate 703 is slidably arranged in the installation groove 702. A support column 704 is fixedly connected to the top of the limit plate 703. The top of the support column 704 is connected to the bottom of the hull 1. A second spring 705 is fixedly installed in the installation groove 702 at the bottom of the limit plate 703.

[0026] In use, the support column 704 slides in the mounting groove 702 through the limiting plate 703, supported by the rear wheel 7. The elastic support of the second spring 705 further buffers and supports the rear wheel 7, thereby improving its stability.

[0027] As can be seen from the above working process, the buffer mechanism 4 enables the device to effectively buffer and support the entire device during operation when it is connected to the tractor via the suspension frame 3. At the same time, in conjunction with the buffer device on the rear wheel 7, the stability of the device during operation can be improved, ensuring its stable operation.

[0028] Further as Figure 2 , Figure 3 and Figure 4 As shown, it is worth noting that the adjustment mechanism 5 includes a crossbeam 501, which is fixedly installed on the right side surface of the hull 1 by bolts. An adjustment rod 502 slides through the right side of the crossbeam 501. A positioning hole 503 is provided on the adjustment rod 502. A front wheel 504 is fixedly connected to the bottom end of the adjustment rod 502. A pin 505 slides through the crossbeam 501. The pin 505 is matched with the positioning hole 503. Several positioning holes 503 are vertically provided on the adjustment rod 502, and the several positioning holes 503 are evenly spaced.

[0029] During use, depending on the conditions of the test site, the sliding pin 505 is used to release the limiting position of the adjusting rod 502, thereby facilitating the sliding of the adjusting rod 502 on the crossbeam 501 to adjust the height between the front wheel 504 and the hull 1, thus matching the conditions of the test site for adjustment work, and improving the convenience of its operation and use. The adjusting rod 502 is positioned by the pin 505 passing through the positioning hole 503.

[0030] This solution has the following working process: When this device is in use, the entire device is installed and connected to the tractor via the suspension frame 3. At this time, depending on the conditions of the test site, the sliding pin 505 is used to release the limiting position of the adjusting rod 502, allowing the adjusting rod 502 to slide on the crossbeam 501, thereby adjusting the height between the front wheel 504 and the hull 1. This adjusts the device to match the conditions of the test site, improving its ease of operation. The adjusting rod 502 is positioned by the pin 505 passing through the positioning hole 503. During the experimental use of the entire device, the damping mechanism... The shock absorber 401 is designed to buffer the vibrations experienced by the hull 1 through the suspension frame 3, thereby reducing the vibration effect. Simultaneously, the connecting block 402 slides within the groove 404, and the first spring 405 provides buffering support, thus achieving a vibration buffering effect. This reduces the vibration transmission from the hull 1 and suspension frame 3 to the tractor, thereby improving its stability. Furthermore, the support column 704 slides within the mounting groove 702 through the limiting plate 703, and the second spring 705 provides elastic support, thereby providing buffering support for the rear wheel 7 and further improving its stability.

[0031] In summary: the buffer mechanism 4 effectively cushions and supports the entire device during operation when it is connected to the tractor via the suspension frame 3. Combined with the buffer device on the rear wheel 7, this improves the stability of the device during operation and ensures stable operation. The adjustment mechanism 5 allows for easy adjustment of the device's height according to the site conditions, facilitating its use and enhancing its practicality.
