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.

[0018] Please refer to Figures 1 to 3, the present utility model provides a technical solution: a pavement engineering laying device, including a push plate 1, a cement slurry barrel 2 is fixed at the top of the push plate 1, a laying discharge port 3 connected to the cement slurry barrel 2 is arranged at the bottom of the push plate 1, a top cover 4 is arranged at the top of the cement slurry barrel 2, a push handle 5 is fixed on one side of the top of the push plate 1 relative to the cement slurry barrel 2, a limit connection mechanism is arranged between the top cover 4 and the cement slurry barrel 2, and a grip anti-slip mechanism is sleeved on the surface of the push handle 5. The limit connection mechanism includes: a connection component, arranged at the connection between the top cover 4 and the cement slurry barrel 2; an operation component, arranged at the top of the top cover 4; a limit component, arranged inside the connection component; and a locking component, arranged at the side of the top cover 4 and connected to the cement slurry barrel 2.

[0019] In this embodiment, preferably, the connection component includes a connection groove 100 opened at the top of the push plate 1 and a connection block 101 fixed at the bottom of the top cover 4, and the connection block 101 is snap-fitted with the connection groove 100.

[0020] In this embodiment, preferably, the operation component includes an operation handle 200 fixed at the top of the top cover 4, which is convenient for lifting the top cover 4 for movement.

[0021] In this embodiment, preferably, the limit component includes limit grooves 300 symmetrically opened on both sides of the connection groove 100 and built-in grooves 301 symmetrically opened on both sides of the connection block 101. A limit buckle 302 is arranged inside the built-in groove 301. By snap-fitting the limit buckle 302 with the limit groove 300, the connection block 101 and the connection groove 100 can be temporarily limited together. A telescopic spring 303 is connected between the limit buckle 302 and the built-in groove 301, which is convenient for driving the limit buckle 302 to reset and bounce up.

[0022] In this embodiment, preferably, sliding grooves 400 are symmetrically opened on the inner wall of the built-in groove 301 and sliding blocks 401 are symmetrically fixed on both sides of the limit buckle 302, and the sliding blocks 401 are slidably connected with the sliding grooves 400.

[0023] In this embodiment, preferably, the locking component includes positioning holes 500 symmetrically opened on both sides of the cement slurry barrel 2 and screw holes 501 symmetrically penetratingly opened on both sides of the top cover 4. Positioning screws 502 passing through the inside of the screw holes 501 and connected to the positioning holes 500 are arranged on both sides of the top cover 4. By screwing and fixedly connecting the positioning screws 502 with the positioning holes 500, the top cover 4 and the cement slurry barrel 2 can be firmly fixed together.

[0024] In this embodiment, preferably, the grip anti-slip mechanism includes a rubber ring 600 sleeved on the surface of the push handle 5, which is convenient for playing a role in grip anti-slip when holding the push handle 5.

[0025] Working principle and usage process of the present utility model: When it is necessary to pour cement slurry into the interior of the cement slurry bucket 2 for laying, first loosen the positioning screw rod 502, and screw its end out of the interior of the positioning hole 500 and into the interior of the threaded hole 501, then the positioning of the top cover 4 can be released. Then, hold the operation handle 200 and lift the top cover 4, so that it drives the connecting block 101 to withdraw from the interior of the connecting groove 100 and squeeze the limit buckle 302. The limit buckle 302 is extruded by an external force, and the telescopic spring 303 withdraws from the interior of the limit groove 300 and retracts into the interior of the built-in groove 301. At the same time, it drives the slider 401 to slide in the interior of the chute 400 to play a role in moving guidance. Subsequently, continue to lift the operation handle 200 to drive the top cover 4 to separate from the cement slurry bucket 2. Then, the interior of the cement slurry bucket 2 can be filled with cement slurry. Then, cover the top cover 4 to provide closed protection for the cement slurry bucket 2. When it is necessary to push the push plate 1 to move, the pusher 5 can be held, and the anti-slip effect of holding can be achieved through the action of the rubber ring 600.

[0026] Although the embodiments of the present utility model have been shown and described (see the above detailed description), for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present utility model. The scope of the present utility model is defined by the appended claims and their equivalents.
