[0002] Pile foundation, pile group foundation and single pile foundation are all called pile foundation, which are common supporting components in the field of construction engineering. The construction of pile foundation is divided into two parts: hole forming and pile forming. Pile forming refers to pouring concrete slurry into the pile foundation hole;

[0003] In the process of pile formation, the existing concrete slurry is usually mixed by mixing equipment and then transported to the construction site for concrete pouring. However, after being transported by vehicles, the concrete inside the vehicle will be uneven due to the static state. In order to make the concrete slurry uniform during pouring, a stirring device is often added above the hole. The existing stirring device can only perform simple one-way stirring, and in cold weather, the concrete will freeze inside, making it difficult for the concrete to enter the hole in a uniform state, affecting the quality of pile construction.

DETAILED DESCRIPTION

[0019] 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.

[0020] See also Figures 1 to 4 , the utility model provides the embodiment:

[0021] A construction pile construction device for a building project comprises a frame 1, a hopper 2 is arranged on the frame 1, a rotating shaft 3 is rotatably arranged on the frame 1, a driving mechanism 4 for driving the rotating shaft 3 to rotate is arranged on the frame 1, one end of the rotating shaft 3 extends into the hopper 2, eight nozzles 5 are installed on the rotating shaft 3, and the rotating shaft 3 is a hollow structure, a stirring structure 6 is arranged on the rotating shaft 3, and the stirring structure 6 comprises a connecting arm 61, a traction seat 62, three scrapers 63 and a lifting plate 64, the connecting arm 61 is tilted and fixedly arranged on the rotating shaft 3, the traction seat 62 is movably arranged at the bottom of the connecting arm 61 through a telescopic structure 7, the three scrapers 63 are equidistantly fixed to the bottom of the traction seat 62, the lifting plate 64 is movably arranged on the traction seat 62 through a reciprocating structure 8, and the lifting plate 64 is tilted.

[0022] See also Figure 1 and 2 For conventional mixing devices, concrete is mostly mixed in one direction. Although bidirectional mixing can be achieved by setting the direction of the motor 41, this method can only make the concrete mixed in a horizontal state, and cannot be mixed in a vertical direction. In this embodiment, when the rotating shaft 3 rotates, the connecting arm 61 first drives the scraper 63 and the lifting plate 64 to revolve synchronously, thereby Figure 2It can be seen that the overall shape of the scraper 63 is arc-shaped, and the overall shape of the lifting plate 64 is spoon-shaped. The arc-shaped scraper 63 can be driven by the telescopic structure 7 and the traction structure 9 to perform horizontal reciprocating movement, so that the concrete in the hopper 2 can be pushed back and forth through the scraper 63, and the scraper 63 is constantly revolving. When the scraper 63 rotates, a part of the concrete can be driven to rotate synchronously through the arc of the scraper 63, thereby realizing the movement of the concrete in the horizontal direction, and the spoon-shaped lifting plate 64 can be driven by the reciprocating structure 8 to perform vertical reciprocating movement. In the process of moving from the lowest point to the highest point, the lifting plate 64 can carry a part of the concrete for height lifting, and the cooperation of the lifting plate 64 and the scraper 63 can achieve uniform mixing of the concrete.

[0023] It should be noted that the size of the scraper 63 increases proportionally as it is further away from the rotating shaft 3, but the overall shape and the central angle of the arc structure of the scraper 63 do not change. The purpose of doing this is that the hopper 2 is circular when viewed from above. In the horizontal section where the scraper 63 is located, there is more concrete in the area far from the center of the circle, while there is less concrete in the area close to the center of the circle. When pouring concrete, it is poured directly to the edge of the hopper 2 through a pipe. In this way, the concrete can be mixed more efficiently and evenly.

[0024] The telescopic structure 7 includes a reciprocating screw 71, a driving shaft 72, a sleeve 73 and a driving tube 74. The sleeve 73 is fixed to the surface of the connecting arm 61. The driving shaft 72 is rotatably set on the surface of the connecting arm 61, and one end of the driving shaft 72 extends into the sleeve 73. One end of the reciprocating screw 71 is fixed to the end surface of the driving shaft 72. The driving tube 74 is slidably set on the inner wall of the sleeve 73 and is connected with the reciprocating screw 71. One end of the driving tube 74 is fixed to the surface of the traction seat 62. One end of the rotating shaft 3 is connected with the hopper 2 through the traction structure 9. The traction structure 9 includes a driving gear 91 fixed on the driving shaft 72, and a gear ring 92 horizontally fixed to the inner wall of the frame 1. The driving gear 91 is connected with the gear ring 92.

[0025] See also Figure 3 and 4 When the connecting arm 61 revolves, it can drive the driving gear 91 to revolve synchronously through the driving shaft 72. When the driving gear 91 revolves, it will always cooperate with the ring gear 92. Therefore, when the driving gear 91 revolves, it will rotate with the cooperation of the ring gear 92. When the driving gear 91 rotates, it can drive the reciprocating screw 71 to rotate in one direction through the driving shaft 72. When the reciprocating screw 71 rotates, it will drive the driving tube 74 to rotate synchronously. However, since one end of the driving tube 74 is circumferentially locked by the reciprocating structure 8, the reciprocating screw 71 can actually drive the driving tube 74 to reciprocate horizontally inside the sleeve 73. When the driving tube 74 moves, it can drive the three scrapers 63 to reciprocate horizontally synchronously through the traction seat 62.

[0026] The reciprocating structure 8 includes a fixed rod 81, a push rod 82 and a drive seat 83. The fixed rod 81 is installed on the side wall of the traction seat 62. The push rod 82 passes through and is elastically arranged inside the fixed rod 81 through a spring. The bottom end of the push rod 82 is fixed to the top of the lifting plate 64, and the top end of the push rod 82 is fixed to the bottom of the drive seat 83. The drive seat 83 is slidably arranged at the bottom of the connecting arm 61. When the scraper 63 is at the lowest point, the spring is in a compressed state, and when the scraper 63 is at the highest point, the spring is in a free state.

[0027] See also Figure 3 When the driving tube 74 drives the traction seat 62 to move horizontally back and forth, it will drive the fixed rod 81 installed on the traction seat 62 to move synchronously. In the initial state, the fixed rod 81 is farthest from the rotating shaft 3, and the spring is in a compressed state. When the driving tube 74 drives the fixed rod 81 to move in the opposite direction close to the rotating shaft 3 through the traction seat 62, since the connecting arm 61 is inclined, the spring can gradually pull the push rod 82 upward through its own elastic force, and the push rod 82 can drive the lifting plate 64 to move upward synchronously.

[0028] It should be noted that when the fixing rod 81 is closest to the rotating shaft 3, it means that the fixing rod 81 has achieved the maximum unidirectional displacement. At this time, the spring is in a free state, and the drive seat 83 is still in contact with the connecting arm 61. The spring coefficient needs to be sufficient to resist the gravity of the concrete adhering to the lifting plate 64 to prevent the spring from being compressed due to the gravity of the concrete, thereby causing the drive seat 83 to detach from the surface of the connecting arm 61. Alternatively, the drive seat 83 can be set as a drive sleeve so that it is directly wrapped around the connecting arm 61 to prevent the drive seat 83 from separating from the connecting arm 61.

[0029] See also Figure 1 and 2 The driving mechanism 4 includes a motor 41, a driving gear 42 and a driven gear 43. The driven gear 43 is fixed to the surface of the rotating shaft 3. The motor 41 is arranged on the frame 1. The driving gear 42 is keyed to the output end of the motor 41. The driving gear 42 is matched with the driven gear 43. The motor 41 drives the rotating shaft 3 to rotate in one direction through the matching of the driving gear 42 and the driven gear 43. At this time, the driving process of the rotating shaft 3 by the motor 41 will not hinder the connection between the rotating shaft 3 and the air supply equipment, so as to realize the supply of hot air to the inside of the hopper 2 by the air supply equipment. In addition, in order to prevent heat loss, a cover plate with a concrete feed port can be installed on the top of the hopper 2.

[0030] In summary, the above are only preferred embodiments of the present invention and are not intended to limit the scope of implementation of the present invention. All equivalent changes and modifications to the shapes, structures, features and spirits described in the claims of the present invention should be included in the claims of the present invention.
