[0019] The following embodiments are used to illustrate the present utility model, but cannot be used to limit the scope of protection of the present utility model. The conditions in the embodiments can be further adjusted according to specific conditions.

[0020] Embodiment
[0021] However, during the use of the existing concrete construction leveling equipment for water conservancy ditches, it is impossible to adjust and use for slopes with different inclination angles, resulting in limited use range. Secondly, the leveling equipment is very inconvenient during the process of moving and transporting, and manual handling is required, greatly increasing the labor intensity of workers.
[0022] For this reason, please refer to Figures 1-3 , the present utility model provides a concrete construction leveling equipment for water conservancy ditches, including: a support plate 1, a middle spreading plate 2 with an isosceles trapezoid cross-section structure is fixedly connected to the bottom end of the support plate 1, a cavity is arranged inside the middle spreading plate 2, two side spreading plates 4 are symmetrically arranged on the inner bottom wall of the cavity, and the bottom ends of the side spreading plates 4 are rotatably connected to the inner bottom wall of the cavity through hinges 41, and a pushing handle 7 is fixedly connected to the rear side wall of the support plate 1;
[0023] It further includes an adjusting structure 3 and a lifting structure 5. The adjusting structure 3 is installed on the middle spreading plate 2 and is connected to the opposite side walls of the two side spreading plates 4. The adjusting structure 3 can synchronously and symmetrically adjust the inclination angles of the two side spreading plates 4. The lifting structure 5 is installed on the support plate 1, and two rollers 6 are symmetrically arranged, and the rollers 6 are all located at the bottom of the support plate 1.
[0024] Further, as shown in Figures 1-3As shown, it is worth specifically explaining that in order to facilitate the synchronous and symmetric adjustment of the inclination angles of the two side spreading plates 4, the adjustment structure 3 is provided with arc plates 31 fixedly connected to the opposite side walls of the two side spreading plates 4. The outer sides of the arc plates 31 are meshed and connected with gears 33 through a plurality of teeth 32. The two gears 33 are meshed with each other and are rotatably connected to the cavity through rotating shafts. One end of one of the rotating shafts extends to the outside of the middle spreading plate 2 and is fixedly connected to the output shaft of the motor a, and the motor a is fixedly connected to the outside of the middle spreading plate 2.
[0025] Among them, the arc plate 31 and the plurality of teeth 32 constitute a sector gear 33, and the thickness of the cavity is the same as that of the arc plate 31 and the side spreading plate 4.
[0026] Furthermore, as Figures 1-3 shown, it is worth specifically explaining that in order to enable the two drums 6 to be lifted and adjusted, the lifting structure 5 is provided with two symmetrically arranged n-shaped rods 51 movably inserted on the support plate 1. The two drums 6 are rotatably connected to the n-shaped rods 51 on the corresponding side. A same synchronous rod 52 is fixedly connected between the tops of the two n-shaped rods 51. A screw rod 53 is threadedly connected to the synchronous rod 52. The top end of the screw rod 53 is fixedly connected with a limiting block, and the bottom end of the screw rod 53 is fixedly connected to the outside of the output shaft of the motor b54, and the motor b54 is fixedly connected to the top end of the support plate 1.
[0027] Among them, in the attached drawing, when the two drums 6 are close to the bottom of the support plate 1, it is convenient for workers to push the device through the push handle 7 to move it on the top edge of the ditch. When the device needs to be carried and moved, the motor b54 can be driven to rotate the screw rod 53, so that the two n-shaped rods 51 move down synchronously, and the two drums 6 are moved away from the support plate 1, and the components on the middle spreading plate 2 are propped up from the ditch, so as to facilitate the subsequent movement and transportation of the device on land.
[0028] In summary, when using this concrete construction leveling equipment for water conservancy ditches, it can be adjusted according to the inclination of the inclined planes on both sides in the ditch. That is, during adjustment, the motor a can be started to drive a gear 33 to rotate. However, the two gears 33 are meshed with each other and are respectively meshed with the arc-shaped plates 31 connected to a plurality of teeth 32, so that the inclination angles of the two side spreading plates 4 can be synchronously adjusted symmetrically, facilitating the construction leveling operation on the inclined planes with different inclinations in the ditch, greatly improving its scope of use. Secondly, when the equipment needs to be moved on land, the motor b 54 can be started, causing the screw rod 53 to rotate, so that the synchronous rod 52 drives the two n-shaped rods 51 to move downward simultaneously, and the middle spreading plate 2 together with the two side spreading plates 4 and the adjustment structure 3 can be lifted from the ditch. With the arrangement of the two rollers 6, it is convenient for manual movement and transportation of the equipment, greatly reducing the labor intensity during manual handling and transportation.
