[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely explain the technical solutions in the embodiments of the utility model. It should be noted that the embodiments and features in the embodiments of the utility model can be combined with each other without conflict, and the described embodiments are only part of the embodiments of the utility model, not all of the embodiments.

[0022] See also Figure 1-2In this embodiment, a device for edging and backrest casting of curb stones includes a material receiving hopper 2, a thick corrugated pipe 5, and a thin corrugated pipe 6. One end of the thick corrugated pipe 5 is connected to the bottom of the material receiving hopper 2, and one end of the thin corrugated pipe 6 is connected to the side wall of the thick corrugated pipe 5. The thin corrugated pipe 6 and the thick corrugated pipe 5 are connected in an "inverted V" shape. The thick corrugated pipe 5 communicates with the inner cavity of the material receiving hopper 2, and the thin corrugated pipe 6 communicates with the thick corrugated pipe 5. Through the arrangement of the thick corrugated pipe 5 and the thin corrugated pipe 6 in this embodiment, the edging and backrest of the curb stone can be cast simultaneously, saving labor and improving work efficiency. The material receiving hopper 2 is welded by steel sheets and is used to collect the concrete from the discharge port of the commercial concrete mixer truck and flow it into the thick corrugated pipe 5 and the thin corrugated pipe 6. The concrete casts the edging and backrest of the curb stone through the thick corrugated pipe 5 and the thin corrugated pipe 6 respectively.

[0023] In this embodiment, a steel cylinder 3 is provided at the bottom end of the material receiving hopper 2. The steel cylinder 3 is connected to the thick corrugated pipe 5 through a buckle 4, and the steel cylinder 3 and the material receiving hopper 2 are welded together.

[0024] In this embodiment, hooks 1 are provided on both sides of the top end of the material receiving hopper 2. The hooks 1 are made by bending round steel and are welded to the material receiving hopper 2, and are used for connecting the material receiving hopper 2 to the discharge port of the commercial concrete mixer truck.

[0025] In this embodiment, a first switch 7 is provided on the thick corrugated pipe 5. The first switch 7 is in plug-in fit with the thick corrugated pipe 5. A second switch 8 is provided on the thin corrugated pipe 6. The second switch 8 is in plug-in fit with the thin corrugated pipe 6. The first switch 7 and the second switch 8 adjust the on-off and opening degree of the thick corrugated pipe 5 and the thin corrugated pipe 6 by means of plug-in fit with the thick corrugated pipe 5 and the thin corrugated pipe 6.

[0026] In this embodiment, both the first switch 7 and the second switch 8 are thin steel sheets.

[0027] In this embodiment, a first pulley seat 9 is slidably provided on the thick corrugated pipe 5. A first pulley 11 is rotatably provided on the first pulley seat 9. A second pulley seat 10 is slidably provided on the thick corrugated pipe 5. A second pulley 12 is rotatably provided on the second pulley seat 10. When the commercial concrete mixer truck moves to drive this device to carry out the edging and backrest casting of the curb stone, the first pulley 11 and the second pulley 12 are respectively used for sliding on the two edge ridges at the top of the curb stone for the thick corrugated pipe 5 and the thin corrugated pipe 6. Since the thick corrugated pipe 5 and the thin corrugated pipe 6 are connected in an "inverted V" shape and there is a resilience force in the corrugated pipe itself, when the commercial concrete mixer truck drives this device forward, the thick corrugated pipe 5 and the thin corrugated pipe 6 move closer to each other, and generate a binding force on the first pulley 11 and the second pulley 12. By adjusting the positions of the first pulley seat 9 and the second pulley seat 10, it is ensured that the first pulley 11 and the second pulley 12 can be closely attached to the two edge ridges at the top of the curb stone and slide stably.

[0028] In this embodiment, the radius of the thick bellows 5 is 5 cm, and the radius of the thin bellows 6 is 2.5 cm. The radii of the thick bellows 5 and the thin bellows 6 in this embodiment can be adaptively adjusted according to actual needs.

[0029] The working principle of this embodiment is as follows:

[0030] First, connect the receiving hopper 2 of the curbstone edging and backrest casting device to the discharge port of the commercial concrete tank truck through the hook 1, then adjust the first pulley seat 9 and the second pulley seat 10 to the appropriate position on the coarse corrugated pipe 5 and the fine corrugated pipe 6 and fix them, fix the first pulley 11 and the second pulley 12 on the coarse corrugated pipe 5 and the fine corrugated pipe 6 on the edges on both sides of the top of the curbstone, the discharge port of the fine corrugated pipe 6 corresponds to the edging side, and the discharge port of the coarse corrugated pipe 5 corresponds to the backrest side. According to different on-site conditions, the concrete flow rate of the commercial concrete tank truck and the opening of the first switch 7 and the second switch 8 can be adjusted to control the concrete flow rate. Finally, adjust the forward speed of the commercial concrete tank truck to adapt to the edging and backrest casting speed until the casting is completed.

The embodiments do not describe all the details in detail, nor do they limit the utility model to the specific implementation methods described. According to the content of this specification, many modifications and changes can be made.
