[0023] To make the objectives, technical solutions, and advantages of the present invention more clearly understood, the present invention is further described below in conjunction with specific embodiments and with reference to the accompanying drawings. It should be understood that these descriptions are merely illustrative and are not intended to limit the scope of the present invention. Furthermore, descriptions of known structures and technologies are omitted in the following description to avoid unnecessary confusion regarding the concepts of the present invention.

[0024] Example 1: Please refer to Figure 1 and Figure 4 , a water conservancy project channel construction leveling device, includes two outer supports 1, the two outer supports 1 are symmetrically distributed on the left and right, and the outer walls of the two outer supports 1 are jointly fixed with a traction frame 25, the main function of the traction frame 25 is to provide a firm connection point for a tractor, excavator or other traction equipment, so that the traction equipment is connected to the leveling device, and each of the outer supports 1 is slidably connected to a movable roller bracket 2 for assisting the device to move back and forth along the channel, and the outer side of the outer support 1 is fixed with an auxiliary roller bracket 3 to provide additional support for the device to ensure its stability and operational safety, and a connecting rod 4 is slidably connected between the two outer supports 1, and a support rod 401 is fixed to the bottom of the connecting rod 4, and a leveling scraper 402 is provided at the bottom of the support rod 401 for leveling the soil or concrete surface in the channel, in addition, the leveling scraper 402 adopts a "V"-shaped structure to better fit the internal shape of the channel and ensure the leveling effect, and the top of the connecting rod 4 is connected by a first mounting seat 5 is fixedly installed with a first cylinder 6, and a hinged frame 7 is provided at the top of the movable rod of the first cylinder 6. A fixed frame 8 is provided on the top of each outer bracket 1. The fixed frame 8 is hinged to the lower end of the hinged frame 7. The first cylinder 6 controls the extension and contraction of the movable rod to expand or retract the hinged frame 7, thereby pushing or pulling the two outer brackets 1 outward or inward to achieve width adjustment. A second cylinder 10 is fixedly installed at the lower part of each outer bracket 1 through a second mounting seat 9. A guide is fixed to the side of the movable roller bracket 2. The guide frame 11 is provided with a sliding seat 1101 in a sliding manner, and the sliding seat 1101 is connected to the bottom end of the movable rod of the second cylinder 10. A positioning wheel 12 is rotatably installed on the sliding seat 1101, and the positioning wheel 12 can only roll left and right, and is used to determine the lateral position of the device and assist the outer bracket 1 in adjusting the width. An elastic member 13 is provided on the guide frame 11, and the two ends of the elastic member 13 are respectively connected to the guide frame 11 and the sliding seat 1101 to provide a reset force for the guide frame 11.

[0025] When performing channel construction and leveling operations, first push the device to the position to be leveled, ensure that the leveling scraper 402 is located inside the channel, and the movable roller bracket 2 is located on the land on both sides of the channel, then adjust the width of the device according to the actual width of the channel, first start the second cylinder 10 to extend its movable rod, push the sliding seat 1101 downward, compress the elastic member 13 until the positioning wheel 12 contacts the channel ground, thereby determining the left and right positions of the device, then start the first cylinder 6, and expand or retract the articulated frame 7 by changing the length of its movable rod, thereby pushing or pulling the two outer brackets 1 outward or inward to adapt to the channel width. At this time, the positioning wheel 12 will roll on the channel ground to assist After the outer bracket 1 moves and the width adjustment is completed, the first cylinder 6 is closed to keep the width unchanged, and then the sliding seat 1101 is driven upward by the second cylinder 10, the pressure of the elastic member 13 is released, the positioning wheel 12 is retracted, and the movable roller bracket 2 is allowed to contact the channel ground again. Finally, a traction device (such as a tractor or an excavator) is used to connect the device through the traction frame 25. The traction device drives the device to move along the channel, and the leveling scraper 402 is used to perform preliminary leveling on the soil inside the channel to create conditions for subsequent concrete paving. After the concrete paving is completed, the traction device is moved again, and the leveling scraper 402 is used to fine-level the concrete surface to ensure the flatness and smoothness of the final surface.

[0026] Example 2: Based on Example 1, please refer to Figure 5 An upper support plate 14 is fixed to the top of the outer bracket 1, and two shock-absorbing springs 15 are connected between the bottom of the upper support plate 14 and the top of the movable roller bracket 2 to provide vertical buffering and reset force for the movable roller bracket 2. Four fixed seats 16 are provided on the inner wall of the outer bracket 1, and a friction wheel 17 is rotatably mounted on the fixed seat 16. The friction wheel 17 is in friction contact with the surface of the movable roller bracket 2 to stabilize the movable roller bracket 2 and reduce its shaking.

[0027] When the device moves on uneven ground, the moving roller bracket 2 will compress or stretch the shock-absorbing spring 15 up and down inside the outer bracket 1 for buffering according to the ground conditions. Specifically, when the moving roller bracket 2 rises due to the bulge of the ground, the shock-absorbing spring 15 is compressed and stores energy. When encountering a depression, the shock-absorbing spring 15 releases energy, pushing the moving roller bracket 2 down and returning to its normal position. This buffering mechanism effectively reduces the bumps and left and right tilting problems of the outer bracket 1 caused by the uneven ground, ensuring that under more complex terrain conditions, the leveling scraper 402 can also maintain good contact with the inside of the channel to achieve high-quality leveling operations. The friction wheel 17 continues to provide lateral support throughout the process to ensure the stability of the moving roller bracket 2.

[0028] See also Figure 6 and Figure 7The rear side of the leveling scraper 402 is fixedly connected to a connecting frame 18 through an angle iron 19. An interception frame 24 is provided inside the connecting frame 18 and is located in front of the conveying plate 21. It is used to intercept impurities such as stones and foreign matter in the soil to prevent them from entering the subsequent processing device. The connecting frame 18 is equipped with transmission rollers 20 that are symmetrically distributed front and back. Each transmission roller 20 is provided with a transmission wheel 22 at both ends. The transmission wheel 22 is in contact with the ground. The transmission roller 20 on the front side is equipped with a conveying plate 21, and the transmission roller 20 on the rear side is equipped with a roller 23.

[0029] When the device levels the soil inside the channel, the excess soil is scraped into the interior by the leveling scraper 402. At this time, the interception frame 24 will intercept impurities such as stones and foreign matter in the soil to prevent them from entering the subsequent processing device. As the device moves, the transmission wheel 22 contacts the ground and rolls with it, driving the transmission roller 20 to rotate. The conveying plate 21 rotates under the drive of the transmission wheel 22 and the transmission roller 20, and transports the scraped soil backward. The roller 23 located at the rear rotates synchronously. The roller 23 presses the soil into sheets through its own rotation and outputs it. Through the above design, the device can not only effectively level the soil inside the channel, but also perform preliminary processing of excess soil to ensure that the soil does not contain large stones or foreign matter, thereby providing better basic conditions for subsequent concrete paving or other construction processes.

Therefore, the detailed description of the disclosed embodiments is intended to illustrate rather than limit the present invention, which shall be defined by the claims.
