DETAILED DESCRIPTION

[0031] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0032] Reference Figure 1 , Figure 2 and Figure 3 The utility model provides an embodiment: an adjustable concrete spraying machine for construction, including a disc 1 and a tooth plate 10, a mixing tank 3 is fixedly connected to the top middle end of the disc 1, a mortar pump 6 is fixedly connected to the top side of the disc 1, the mortar pump 6 is connected to the mixing tank 3 through a pipeline, the output end of the mortar pump 6 is fixedly connected to a connecting pipe 7, a fixing frame 12 is fixedly connected to the top of the disc 1 near the mortar pump 6, a motor 11 is fixedly connected to the top of the fixing frame 12, and a gear is fixedly connected to the output end of the motor 11. 9. The gear 9 is meshed with the tooth plate 10. The outside of the tooth plate 10 is fixedly connected with a nozzle 8. The end of the connecting pipe 7 away from the mortar pump 6 is connected to the nozzle 8. The outside of the tooth plate 10 is fixedly connected with a connecting block 18 on both sides. The outside of the connecting block 18 is fixedly connected with a pulley 19. The top of the wheel disc 1 is fixedly connected to one side close to the fixed frame 12. The outsides of the two pulleys 19 are slidably connected to the inner walls of the corresponding limit shells 13. A control box 2 is provided on the other side of the top of the wheel disc 1, and a feed pipe 5 is fixedly connected to the top of the mixing tank 3.

[0033] Specifically, the wheel plate 1 is the supporting base of the entire equipment, and can move the entire equipment to the place where work is needed. The mixing tank 3 is a key component for storing and mixing concrete raw materials. The mortar pump 6 is the core component of concrete transportation, which is connected to the mixing tank 3 through a pipeline. It can effectively suck the mixed concrete from the mixing tank 3 and transport it to the nozzle 8 through the connecting pipe 7 for spraying. The connecting pipe 7 is a pipeline connecting the mortar pump 6 and the nozzle 8. The length and curvature of the connecting pipe 7 can be adjusted according to construction requirements, so as to facilitate the transportation of concrete to different construction locations. The fixed frame 12 supports the motor 2 11 to ensure that the motor 2 11 will not shift during operation. The gear 9 and the tooth plate 10 are key components for realizing the height adjustment of the nozzle 8. When the gear 9 is driven to rotate by the motor 2 11, it meshes with the tooth plate 10, so that the tooth plate 10 moves up and down in the vertical direction. It can ensure that the nozzle 8 remains stable during the movement and achieves precise spraying. The nozzle 8 is the outlet for concrete spraying. The pulley 19 slides on the inner wall of the limit shell 13 to ensure that the tooth plate 10 remains stable during the up and down movement. It can enhance the stability of the tooth plate 10 during the lifting process. The limit shell 13 limits the movement range of the pulley 19, which can enhance the stability of the tooth plate 10 during the lifting process. It is used to control the start, stop and adjustment of components such as motor 1 4, motor 2 11, and mortar pump 6. The operator can easily adjust the various parameters of the equipment through the control box 2 to achieve efficient and accurate concrete spraying. The feed pipe 5 is used to add concrete raw materials into the mixing tank 3.

[0034] Reference Figure 1 and Figure 4A stirring assembly is provided inside the stirring tank 3, and the stirring assembly is used to stir the inside of the stirring tank 3. The stirring assembly includes a motor 4, and the motor 4 is fixedly connected to the top of the stirring tank 3. The output end of the motor 4 is fixedly connected to a connecting rod 14, and the outer side of the connecting rod 14 is fixedly connected to two stirring frames 15. The outer side of the connecting rod 14 is fixedly connected to multiple stirring rods 16, and the bottom of the stirring rod 16 is fixedly connected to a stirring rod 2 17.

[0035] Specifically, the motor 14 is the power source of the mixing assembly. When the motor 14 is started, the connecting rod 14 is driven to rotate. The connecting rod 14 transmits the rotational power of the motor 14 to the mixing frame 15, so that the mixing frame 15 can rotate inside the mixing tank 3. The mixing frame 15 is provided with stirring blades on the outside, which can effectively turn and mix the concrete raw materials during the rotation process. The stirring rod 16 and the stirring rod 2 17 can be driven by the connecting rod 14 to rotate, which can further improve the mixing effect and efficiency.

[0036] Reference Figure 4 and Figure 6 A cleaning component is provided on the outside of the stirring component, and the cleaning component is used to clean the inner wall of the stirring tank 3. The cleaning component includes a plurality of telescopic rods 20, one end of the telescopic rod 20 is fixedly connected to the outside of the stirring frame 15, a spring 21 is sleeved on the outside of the telescopic rod 20, the telescopic end of the telescopic rod 20 is fixedly connected to a connecting plate 22, a plurality of brushes 23 are fixedly connected to the outside of the connecting plate 22, one end of the spring 21 is fixedly connected to the outside of the stirring frame 15, and the other end of the spring 21 is fixedly connected to the outside of the connecting plate 22.

[0037] Specifically, the telescopic rod 20 and the spring 21 provide elastic force for the connecting plate 22, so that the brush 23 on the connecting plate 22 is closely attached to the inner wall of the mixing tank 3. Since the brush 23 is closely attached to the inner wall of the mixing tank 3, it moves with the rotation of the mixing frame 15. The material of the brush 23 is soft and tough, and can effectively remove concrete residues on the inner wall of the mixing tank 3.

[0038] Working principle: First, add an appropriate amount of concrete raw materials into the mixing tank 3 through the feed pipe 5. Then, start the motor 14, and the motor 14 drives the connecting rod 14 to start rotating. The rotation of the connecting rod 14 drives the mixing frame 15 and the mixing rod 16 and the mixing rod 2 17 to rotate and stir. The concrete raw materials in the mixing tank 3 are evenly mixed, ensuring the quality of the concrete. When the concrete is evenly mixed, start the mortar pump 6. The mortar pump 6 sucks the concrete in the mixing tank 3 through the pipeline and delivers it to the nozzle 8 through the connecting pipe 7. In this process, the gear 9 can be driven to rotate by starting the motor 2 11, so that the tooth plate 10 is driven to move up and down, and the pulleys 19 on both sides of the outer side of the tooth plate 10 slide on the inner wall of the limit shell 13, thereby driving the nozzle 8 to move up and down in height to achieve precise spraying. After the construction is completed, turn off the motor 2 11 and the mortar pump 6, and the motor 14 drives the rotation of the mixing frame 15. Under the elastic force of the telescopic rod 20 and the spring 21, the brush 23 on the connecting plate 22 is close to the inner wall of the mixing tank 3. The brush 23 on the connecting plate 22 cleans the inner wall of the mixing tank 3 to remove the residual concrete, thereby ensuring that the mixing tank 3 is clean and hygienic.

[0039] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
