[0021] Clearly, the described embodiments are merely a part of the embodiments of the present utility model, rather than all the embodiments.

[0022] Please refer to Figures 1-4 The utility model provides a technical scheme: a concrete delivery pump paving device, it is including: concrete delivery pump paving pipe 1 and concrete chute 2, concrete delivery pump paving pipe 1 is as the main passage of concrete delivery, and the paving pipe is directly connected concrete delivery pump, and the pumped concrete is guided to the designated position. Concrete delivery pump paving pipe 1 lower half outer wall both sides are equipped with fixed shaft 5, fixed shaft 5, not only be used for with the connection and positioning of concrete chute 2, still ensure the relative stability between paving pipe and chute, make things convenient for the angle and direction adjustment. Concrete chute 2 both sides top are equipped with sawtooth plate 3, and the chute is located below the paving pipe export, is responsible for receiving and guiding concrete flow to the designated paving area, realizes the lateral spreading of concrete, and the sawtooth plate 3 is equipped with sawtooth groove 4 in, and the fixed shaft 5 is located in sawtooth groove 4, and the sawtooth groove 4 has several, and the outer wall of one side of concrete delivery pump paving pipe 1 is equipped with electric hydraulic telescopic rod 8, and one end of electric hydraulic telescopic rod 8 is connected with the outer wall of one end of concrete chute 2, and the concrete chute 2 is located below the export of concrete delivery pump paving pipe 1. Concrete delivery pump paving device uses, and concrete is conveyed to the discharge in concrete delivery pump paving pipe 1 under the pumping of delivery pump, and under the guidance of concrete chute 2, concrete can realize lateral paving.

[0023] Several sawtooth grooves 4 are equidistantly arranged on the sawtooth plate 3. The equidistantly arranged sawtooth grooves 4 mean that the fixed shaft 5 has multiple evenly distributed support points on the sawtooth plate 3. This allows the operator to adjust the angle of the chute 2 in smaller steps, thereby achieving fine control of the flow of concrete.

[0024] One side of the outer wall of the concrete delivery pump paving pipe 1 is provided with a rotating seat 7, and one end of the electric hydraulic telescopic rod 8 is rotatably connected with the rotating seat 7. The rotating seat 7 is arranged on one side of the outer wall of the concrete delivery pump paving pipe 1, and its main function is to serve as a connecting bridge between the electric hydraulic telescopic rod 8 and the paving pipe. Through the rotating seat 7, the electric hydraulic telescopic rod 8 can be connected to the paving pipe in a manner allowing rotation, thereby allowing the chute 2 to make more complex angle adjustments under the action of the telescopic rod.

[0025] One end of the outer wall of the concrete chute 2 is fixedly provided with a fixed seat 11, and one end of the electric hydraulic telescopic rod 8 is fixedly connected with the fixed seat 11. The fixed seat 11 is fixedly arranged on the outer wall of one end of the concrete chute 2, and its main function is to serve as a connecting point between the electric hydraulic telescopic rod 8 and the chute.

Vibration can reduce the friction inside the concrete, making it easier to slide and spread in the chute, thereby improving the paving efficiency and uniformity. When the vibration motor 9 is started, it will generate high-frequency vibrations, and these vibrations are transmitted to the concrete through the chute. The vibration effect can destroy the agglomerated structure inside the concrete, making the particles more dispersed, thereby improving the fluidity. The protective shell 6 tightly wraps the outside of the vibration motor 9, and its main function is to protect the vibration motor from damage from the external environment. The heat dissipation hole 10 is formed in one side of the protective shell 6, and its main function is to allow air to circulate and help the vibration motor dissipate heat.
