Description

Technical Field

[0001] The utility model relates to the technical field of neat cement spraying machines, in particular to a self-cleaning neat cement spraying machine. Background Art

[0002] In the production process of PCCP products, there is a key link, that is, it is necessary to wind circumferential prestressed steel wires on the outer side of the pipe core. However, before that, a layer of neat cement must be carefully sprayed on the surface of the pipe body, and at this time, a neat cement spraying machine is needed.

[0003] At present, in the actual application process of the neat cement spraying machine, many serious problems have emerged. First of all, after use, the cleaning work of the neat cement tank is a headache. Usually, it is necessary to manually hold the water pipe to flush its inner wall. However, this is by no means an easy task. Due to the structural characteristics of the neat cement tank itself, its depth is often relatively large. When facing such a deep neat cement tank, the operator has to bend down or even probe into the inner bottom to flush. This operation method is not only extremely laborious, causing a greater burden on the operator's body, but also has certain safety risks. The posture of bending down and probing makes it difficult for the operator to apply force, and the flushing effect is also greatly reduced. At the same time, due to the limited internal space of the neat cement tank, it is inconvenient for the operator to move inside, and it is easy to collide and scratch, causing accidental injuries to the body. In addition, maintaining this uncomfortable posture for a long time is likely to cause fatigue and damage to the operator's waist and neck. Over time, it may lead to serious occupational diseases. To address this problem, a self-cleaning neat cement spraying machine is proposed here. Summary of the Utility Model

Detailed implementation manners

[0021] 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 of the embodiments.

[0022] Referring to Figures 1-4 , the self-cleaning grout spraying machine, the core components of which include a grout tank 1 and a spray head 10. Multiple support legs 2 are stably installed at the bottom of the grout tank 1 to provide stable support for the entire device. The spray head 10 is machined, with a grout pipe at the upper part, an overflow hole (pressure relief hole) at the lower part, and an air pipe at the tail. After the grout enters the spray head 10, it is sprayed out through compressed air.

[0023] The grout tank 1 has a cylindrical conical bottom, which is not prone to causing slurry precipitation and caking compared with the traditional flat-bottom grout tank 1, thus making it more convenient to clean.

[0024] An installation plate 3 is provided on the grout tank 1, and this installation plate 3 plays an important role. On the installation plate 3, a stirring shaft 13 is rotatably installed, and multiple stirring rods 15 are carefully installed on the stirring shaft 13, and they work together to ensure the uniform mixing of the grout.

[0025] A stirring motor 11 is equipped on the installation plate 3, and the stirring motor 11 is tightly connected to the stirring shaft 13 through a rotating mechanism. It is worth mentioning that a unique cavity 17 is provided inside the stirring shaft 13, and multiple water spray nozzles 18 communicating with the cavity 17 are provided on the outer wall of the stirring shaft 13. At the same time, a water inlet pipe 19 is rotatably installed on the stirring shaft 13, and this design lays the foundation for the subsequent self-cleaning function. The water inlet pipe 19 can be connected to a pump body to pump in clear water.

[0026] A drain pipe 16 is installed on the bottom wall of the grout tank 1 to discharge the wastewater after cleaning.

[0027] A sewage pump 6 is provided on the side of the grout tank 1 through a sturdy mounting bracket 5, and a discharge pipe 7 connected to the sewage pump 6 is provided on the bottom wall of the grout tank 1 to ensure that the grout can be smoothly transported to the spray head 10.

[0028] The sewage pump 6 is connected to the spray head 10 through a connecting mechanism, ensuring the efficient spraying of the grout. Among them, the rotating mechanism includes a driving gear 12 installed on the output shaft of the stirring motor 11, and a transmission gear 14 is installed on the stirring shaft 13. The driving gear 12 and the transmission gear 14 are perfectly meshed to achieve stable and efficient power transmission.

[0029] The connecting mechanism includes a tee pipe 8 installed on the sewage pump 6. One end of the tee pipe 8 is connected to a connecting pipe 9, and the other end of the tee pipe 8 extends into the grout tank 1. This design cleverly realizes the circulation and transportation of the grout.

[0030] Multiple bolts 4 are installed on the mounting plate 3, and a plurality of threaded connection grooves corresponding to the bolts 4 are provided on the neat cement tank 1, ensuring the firm installation of the mounting plate 3.

[0031] In addition, the first valve is a one-way valve, effectively preventing the backflow of neat cement. The second valve is an electric valve, facilitating automatic control.

[0032] When the utility model is in use, first, the neat cement raw materials are put into the neat cement tank 1 with a cylindrical conical bottom. The stirring motor 11 on the mounting plate 3 is started, and the driving gear 14 on the stirring shaft 13 is driven to rotate by the driving gear 12 on the output shaft of the stirring motor 11, so that the stirring shaft 13 rotates. Multiple stirring rods 15 on the stirring shaft 13 work together to fully stir the neat cement, ensuring the uniform mixing of the neat cement.

[0033] When spraying operation is required, the discharge pipe 7 at the bottom wall of the neat cement tank 1 conveys the neat cement to the sewage pump 6 on the side mounting frame 5. The sewage pump 6 works, and through the tee pipe 8 and the connecting pipe 9 in the connecting mechanism, the neat cement is smoothly conveyed to the nozzle 10, realizing efficient neat cement spraying.

[0034] During the spraying process, the design that one end of the tee pipe 8 extends into the neat cement tank 1 cleverly realizes the circulation of the neat cement, ensuring the fluidity and uniformity of the neat cement.

[0035] After the neat cement spraying operation is completed, the self-cleaning function is started. The water inlet pipe 19 is connected to the pump body, and clear water is pumped into the cavity 17 inside the stirring shaft 13 and then sprayed out from a plurality of water spraying ports 18 on the outer wall of the stirring shaft 13. At the same time, the stirring shaft 13 continues to rotate, driving the stirring rod 15 to fully wash the inside of the neat cement tank 1. The waste water after washing is discharged through the drain pipe 16 at the bottom wall of the neat cement tank 1.

[0036] The above is only the preferred specific embodiment of the utility model, but the protection scope of the utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the utility model, according to the technical solution of the utility model and its inventive concept, makes equivalent substitution or change, and should be covered within the protection scope of the utility model.
