[0028] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0029] Please refer to Figures 1 - 3 , in the embodiment of the present utility model, a civil engineering construction screeding device includes a connecting plate 1, a fixing frame 2 is fixed at one end of the connecting plate 1, a roller 3 is rotatably connected inside the fixing frame 2, and a reciprocating mechanism 4 arranged on the connecting plate 1 and the roller 3;

[0030] The reciprocating mechanism 4 includes a transmission unit and a screeding unit;

[0031] The transmission unit is used to provide power for the movement of the screeding plate 406;

[0032] The screeding unit is used to reciprocate and screed the concrete;

[0033] The transmission unit includes a first rotating rod 401, a transmission rod 402, a second rotating rod 403, and an abutting block 404;

[0034] The first rotating rod 401 is fixed at the end of the roller 3 and extends into the fixing frame 2, and the first rotating rod 401 is used to drive one end of the transmission rod 402 to rotate circumferentially;

[0035] The transmission rod 402 is eccentrically rotatably connected to the outer wall of the end of the first rotating rod 401, and the transmission rod 402 is used to drive the second rotating rod 403 to rotate;

[0036] The second rotating rod 403 is rotatably connected to the inner wall of the fixing frame 2 and extends into the connecting plate 1, and the second rotating rod 403 is used to drive the abutting block 404 to rotate synchronously;

[0037] The abutting block 404 is fixed on the outer wall of the second rotating rod 403, and the abutting block 404 is used to give the slider 405 a moving thrust;

[0038] The screeding unit includes a slider 405, a screeding plate 406, and a spring 407;

[0039] The slider 405 is fixed to the top end of the screed board 406 and extends into the inside of the connecting plate 1. The slider 405 is used to guide the movement of the screed board 406.

[0040] The screed board 406 is fixed to the bottom end of the slider 405 and is located below the connecting plate 1. The screed board 406 is used to level the concrete.

[0041] Both ends of the spring 407 are respectively clamped inside the connecting plate 1 and on the outer wall of the slider 405. The spring 407 is used to provide a reset elastic force for the moving screed board 406.

[0042] In this embodiment: When using this device, by placing the connecting plate 1 on the upper surface of the concrete to be leveled, manually pulling the connecting plate 1 to move, the moving connecting plate 1 synchronously pulls the fixing frame 2 and the roller 3 to move. The roller 3 in contact with the concrete will rotate, and the rotating roller 3 synchronously drives the first rotating rod 401 to rotate, so that one end of the transmission rod 402 eccentrically rotationally connected to the end of the first rotating rod 401 rotates circumferentially. Then, the other end of the transmission rod 402 rotates circumferentially synchronously to drive the second rotating rod 403 to rotate. The rotating second rotating rod 403 synchronously drives the abutting block 404 to rotate, so that the slider 405 within the rotation trajectory range of the abutting block 404 receives a thrust from the abutting block 404 and axially moves. The axially moving slider 405 synchronously drives the screed board 406 to axially move, so that the screed board 406 moves again during the process of moving with the connecting plate 1. And when the abutting block 404 no longer contacts the slider 405, the slider 405 will reset under the elasticity of the spring 407, so that the screed board 406 moves again, reciprocally leveling the concrete at the position where the screed board 406 is located, improving the leveling fineness and reducing the manual labor intensity.

[0044] In this embodiment: When the abutting block 404 rotates with the rotation of the second rotating rod 403, the spherical end of the abutting block 404 will contact the outer wall of the slider 405, and the arc-shaped end of the abutting block 404 will exert a thrust on the slider 405, causing the screeding plate 406 at the top of the slider 405 to move axially. It should be noted that the extrusion force received by the slider 405 is greater than the restoring elastic force provided by the spring 407.
