[0012] In the above technical solution, the trenching device for water conservancy projects also includes: a baffle; the baffle is L-shaped, installed at the bottom of the lifting plate, and located on one side of the breaking wheel.

[0013] The trenching device for water conservancy projects of this utility model has the following advantages compared with the prior art: 1. By positioning two support plates on the outside of the base plate and placing the breaking wheel between the two support plates, the breaking wheel is positioned on the outside of the base plate.

[0014] 2. By setting two sliding grooves at the bottom of the adjusting seat and installing two slide rails on the base plate, with the two slide rails passing through the two sliding grooves respectively, the adjusting seat can move along the two slide rails, thus preventing the adjusting seat from shifting during movement and improving the stability of the adjusting seat's movement; by connecting the connecting plate to the adjusting seat and connecting the connecting plate to the electric push rod, the electric push rod can drive the adjusting seat to move through the connecting plate, thereby adjusting the position of the adjusting seat and the breaking wheel, ensuring that the breaking wheel is aligned with the position to be trenched, and thus improving the accuracy of trenching the ground.

[0018] 6. By connecting the second pulley to the drive shaft and simultaneously fitting the belt around the outside of both the first and second pulleys, when the second motor drives the first pulley to rotate, the first pulley drives the drive shaft to rotate via the belt and the second pulley, thereby providing power for rotating the drive shaft.

[0019] 7. By placing the clearance groove at the bottom of the lifting plate and positioning it above the breaking wheel, interference between the breaking wheel and the lifting plate can be avoided. At the same time, the distance between the highest point of the breaking wheel and the lifting plate can be increased, thereby preventing a small amount of soil from sticking to the bottom of the lifting plate and affecting the rotation of the breaking wheel, thus improving the user experience of the product.

[0020] 8.

[0024] By installing the adjustment mechanism 11 on the base plate 10 and connecting the adjustment seat 12 to the adjustment mechanism 11, the base plate 10 supports the adjustment mechanism 11, thereby enabling the adjustment mechanism 11 to drive the adjustment seat 12 to move and adjust the position of the adjustment seat 12. By installing the lifting mechanism 13 on the adjustment seat 12 and connecting the lifting plate 14 to the lifting mechanism 13, the adjustment seat 12 supports the lifting mechanism 13, thereby enabling the lifting mechanism 13 to drive the lifting plate 14 to move up and down, thereby adjusting the height of the lifting plate 14. By installing two support plates 15 at the bottom of the lifting plate 14, and passing the drive shaft 16 sequentially through the two support plates 15, with both ends of the drive shaft 16 rotatably connected to the two support plates 15 respectively, the two support plates 15 support the drive shaft 16, allowing the drive shaft 16 to rotate within the two support plates 15. By mounting the soil-breaking wheel 17 on the outside of the drive shaft 16 and positioning the soil-breaking wheel 17 between the two support plates 15, the drive shaft 16 can drive the soil-breaking wheel 17 to rotate, enabling the soil-breaking wheel 17 to groove the ground. By installing the drive mechanism 18 on the lifting plate 14 and connecting the drive mechanism 18 to the drive shaft 16, the lifting plate 14 can drive the drive mechanism 18 to move up and down, allowing the drive mechanism 18 to drive the drive shaft 16 to rotate, thus providing power for rotating the drive shaft 16. By connecting four universal rollers 19 to the bottom of the base plate 10, the base plate 10 can move on the ground via the four universal rollers 19, thereby improving the flexibility of product movement.

[0025] When using the product, first mark the location to be grooved on the ground with lime; then, move the product to the predetermined position using the four universal rollers 19; next, activate the adjustment mechanism 11, which moves the adjustment seat 12 to align the soil-breaking wheel 17 with the marked position; then, activate the drive mechanism 18, which rotates the drive shaft 16; then, activate the lifting mechanism 13, which moves the lifting plate 14 downwards to embed the soil-breaking wheel 17 into the ground, thereby adjusting the grooving depth of the soil-breaking wheel 17; finally, push the base plate 10 to make the soil-breaking wheel 17 groove the ground.

[0026] By employing the above structure, with the two support plates 15 positioned outside the base plate 10 and the breaking wheel 17 positioned between the two support plates 15, the breaking wheel 17 is positioned outside the base plate 10.
