[0002] Pipe piles are hollow cylindrical slender concrete prefabricated components made by prestressing technology and centrifugal forming. They are mainly composed of a cylindrical pile body, end plates and steel sleeves. They are widely used in industrial and civil buildings, bridges, ports and docks, water conservancy projects and other projects. Usually, pipe piles are in the field of pile foundations and are subjected to greater pressure during use. During processing, the pile body must first be made of steel bars and then filled with concrete, followed by steps such as mold closing, centrifugation, steaming and demoulding.

The process of manual water proportioning is relatively complicated, time-consuming and labor-intensive, and easily affects work efficiency. In addition, the accuracy of manual proportioning is low, which easily leads to an increase in the yield of defective products.

[0048] The top ring 23 is arranged near the top of the rotating shaft 22, and the bottom ring 28 is arranged near the bottom of the rotating shaft 22. A plurality of evenly distributed stirring rods 27 are fixed on the surface of the rotating shaft 22, and the stirring rods 27 are located between the top ring 23 and the bottom ring 28.

[0049] When in use, the mixing box 4 is provided with a rotating shaft 22, a top ring 23, a bottom ring 28 and a stirring rod 27 and other structures, which can achieve full stirring and mixing of the raw materials.

[0052] Working principle: In actual use, by starting the third motor 31, its output end drives the transmission shaft 36 to rotate, thereby prompting the second sprocket 35 to start rotating. Through the transmission effect of the chain 34, the bottom shaft 32 and the baffle 2 rotate accordingly, so that the baffle 2 is moved away from the top of the feeding barrel 3, which is convenient for operators to use multiple feeding barrels 3 to feed materials. When quantitative feeding of water is carried out, the water pump 15 is started to transport the water in the water tank 14 to the transition barrel 12. At this time, the solenoid valve 41 controls the delivery pipe 40 to remain in a closed state. Since the transition barrel 12 is made of acrylic plate, it is convenient to observe the water volume inside it. Combined with the scale bar 11 on the outer surface of the transition barrel 12, the required water volume can be accurately controlled. When the water volume reaches the requirement, the water pump 15 is turned off, and the delivery pipe 40 is opened through the solenoid valve 41 to accurately transport the quantitative water to the mixing box 4. When the feeding is completed, the conveying pipe 40 is opened. By starting the second motor 21, its output end will drive the rotating shaft 22 to rotate continuously, and the set several stirring rods 27 will continue to perform stirring operations to ensure uniform mixing of the raw materials. At the same time, the extension rod 24 will rotate synchronously, thereby driving the vertical plate 25 to rotate continuously, so that the set hanging strips 26 continuously scrape the inner wall of the mixing box 4 to avoid excessive accumulation of raw materials on the inner wall of the mixing box 4. This avoids the following problems: the existing proportioning equipment cannot proportion the water added to the raw materials, and manual proportioning is required. The process of manual proportioning of water is relatively complicated, time-consuming and labor-intensive, and it is easy to affect work efficiency. In addition, the accuracy of manual proportioning is low, which is easy to cause an increase in the yield of defective products. At the same time, during the stirring process, the mixed product has adhesion and is easy to accumulate on the inner wall of the stirring device, which is a more troublesome problem in the later cleaning.

[0053] A production method of a raw material proportioning device for manufacturing high-strength concrete pipe piles, comprising the following steps:

[0054] S1: After the third motor 31 is started, its output end drives the transmission shaft 36 to rotate, thereby causing the second sprocket 35 to start rotating. Through the transmission effect of the chain 34, the bottom shaft 32 and the baffle 2 rotate accordingly, so that the baffle 2 is moved away from the top of the feeding barrel 3, making it easier for operators to use multiple feeding barrels 3 to feed materials;

[0055] S2: When quantitative water delivery is performed, the water pump 15 is started to deliver the water in the water tank 14 to the transition tube 12. At this time, the solenoid valve 41 controls the delivery pipe 40 to remain in a closed state. Since the transition tube 12 is made of acrylic plate, it is convenient to observe the water volume inside it. Combined with the scale bar 11 on the outer surface of the transition tube 12, the required water volume can be accurately controlled. When the water volume reaches the requirement, the water pump 15 is turned off, and the delivery pipe 40 is opened through the solenoid valve 41 to accurately deliver the quantitative water to the mixing box 4;

[0056] S3: After the feeding is completed, the second motor 21 is started, and the output end of the second motor 21 drives the rotating shaft 22 to rotate continuously, and the plurality of stirring rods 27 are continuously stirred;

[0057] S4: While the mixing operation is being performed, the extended rod 24 will rotate synchronously, thereby driving the vertical plate 25 to rotate continuously, so that the hanging bar 26 can continuously scrape the inner wall of the mixing box 4 to avoid excessive accumulation of raw materials on the inner wall of the mixing box 4.

[0058] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.

10. A method for producing a raw material proportioning device for manufacturing high-strength concrete pipe piles according to any one of claims 1 to 9, characterized in that: The following steps are involved: S1: After the third motor (31) is started, its output end drives the transmission shaft (36) to rotate, thereby causing the second sprocket (35) to start rotating. Through the transmission effect of the chain (34), the bottom shaft (32) and the baffle (2) rotate accordingly, so that the baffle (2) moves away from the top of the feeding barrel (3), making it easier for operators to use multiple feeding barrels (3) to feed materials; S2: When quantitative water delivery is performed, the water pump (15) is started to deliver the water in the water tank (14) to the transition tube (12). At this time, the solenoid valve (41) controls the delivery pipe (40) to remain in a closed state. Since the transition tube (12) is made of acrylic plate, it is convenient to observe the water volume inside it. Combined with the scale bar (11) on the outer surface of the transition tube (12), the required water volume can be accurately controlled. When the water volume reaches the required amount, the water pump (15) is turned off, and the delivery pipe (40) is opened through the solenoid valve (41) to accurately deliver the quantitative water to the mixing box (4); S3: After the feeding is completed, the second motor (21) is started, and the output end of the second motor (21) drives the rotating shaft (22) to rotate continuously, and the plurality of stirring rods (27) are continuously stirred; S4: While the mixing operation is being performed, the outer extension rod (24) is rotated synchronously, thereby driving the vertical plate (25) to continuously rotate, so that the hanging bar (26) is continuously scraped against the inner wall of the mixing box (4), thereby preventing excessive accumulation of raw materials on the inner wall of the mixing box (4).
