[0022] Please see Figures 1 to 4 This utility model provides a technical solution: a spiral concrete placing boom for convenient feeding, including a workbench 1, on which a plate 2 is connected. The plate 2 supports the middle area of ​​the mold. A double-ended threaded rod 3 is rotatably connected to the workbench 1. Rotating the double-ended threaded rod 3 moves the plate 5. The distance between the two sets of plates 5 can be adjusted to provide support for one end and the other end of molds of different lengths. The double-ended threaded rod 3 is movably connected to the plate 2. A motor 4 is installed at one end of the workbench 1. The model of the motor 4 can be selected according to the actual situation. The output end of the motor 4 is connected to the double-ended threaded rod 3, and the motor 4 drives the double-ended threaded rod 3 to rotate. A double-headed threaded rod 3 is threadedly connected to two sets of plates 5. A threaded rod 6 is rotatably connected to the worktable 1. Rotating the threaded rod 6 moves the plate 7, which in turn moves the material conveying pipe 13 to distribute material to different areas of the mold. The threaded rod 6 is threadedly connected to the plate 7. A motor 8 is installed at one end of the worktable 1. The model of motor 8 can be selected according to actual needs. The output end of motor 8 is connected to the threaded rod 6, and motor 8 drives the threaded rod 6 to rotate. A hydraulic cylinder 9 is installed at one end of the plate 7. The model of hydraulic cylinder 9 can be selected according to actual needs. One end of hydraulic cylinder 9 is connected to a frame 10, and hydraulic cylinder 9 moves the frame 10. This, in turn, moves the conveying pipe 13, adjusting its height to some extent and preventing collisions between the conveying pipe 13 and the mold when producing cement poles of different sizes. The frame 10 is connected to a hopper 11. Concrete is poured into the hopper 11 and, under gravity, falls through the outlet 12 into the conveying pipe 13. One end of the hopper 11 is connected to the outlet 12, which is connected to the conveying pipe 13. A motor 14 is installed at one end of the conveying pipe 13. The model of the motor 14 can be selected according to actual conditions. The output end of the motor 14 is connected to a rod 15. The motor 14 drives the rod 15 to rotate, and the rod 15 drives the screw... The rotating blades 16 convey concrete. The rod body 15 is rotatably connected to the conveying pipe 13. The rod body 15 is connected to multiple sets of spiral blades 16. The diameter, pitch, and shape of the spiral blades 16 are specially designed according to the needs of cement pole production. Generally, variable pitch blades are used. The pitch is larger at the feeding end, which can quickly introduce concrete. As the concrete is conveyed, the pitch gradually decreases to increase the conveying pressure of the concrete and ensure that the concrete is evenly distributed into the mold. The height of the conveying pipe 13 is adjusted by the hydraulic cylinder 9, which to some extent avoids the problem of disassembling the device and making adjustments when producing cement poles of different sizes, thus improving efficiency to a certain extent.

[0023] The outer wall of the conveying pipe 13 is connected to a plate 17. One end of the plate 17 is connected to a frame 18. Two sets of wheels 19 are placed on the workbench 1. One end of each set of wheels 19 is connected to a block 20. One end of each set of blocks 20 is connected to a threaded rod 21. Multiple sets of threaded rods 21 are movably connected to the corresponding frame 18. Multiple sets of threaded rods 21 are threadedly connected to two sets of nuts 22. One end of the frame 10 is connected to a reinforcing rib 27, which strengthens the structural strength of the frame 10 to a certain extent. The wheels 19 move with the conveying pipe 13, which can improve the movement stability of the conveying pipe 13 to a certain extent. When the conveying pipe 13 is adjusted, it will drive the wheels 19 to move together. Rotating the nut 22 removes the restriction on the block 20, moves the block 20, and makes the wheels 19 contact the workbench 1 again.

[0024] Among them, one end of each of the multiple sets of nuts 22 is connected to a washer 23, and the multiple sets of washers 23 are respectively pressed against the corresponding frame 18. The washers 23 can absorb vibration to a certain extent and prevent the nuts 22 from loosening.

[0025] The workbench 1 has two sets of slide grooves 24, and each of the two sets of plates 5 is connected to one end of two sets of sliders 25. Multiple sets of sliders 25 are slidably connected to the corresponding slide grooves 24. The sliders 25 and the slide grooves 24 cooperate to guide the movement of the plates 5.

[0026] Among them, both sets of plate body 25 and plate body 12 are V-shaped and one end of the V-shape is attached with a rubber pad 26. The V-shaped design can provide support for molds of different diameters to a certain extent, and the rubber pad 26 can increase the friction with the mold and improve the placement stability to a certain extent.

[0027] Among them, a round rod 28 is connected to the workbench 1. The round rod 28 is slidably connected to the plate 3 7 and guides the plate 3 7.

[0028] The specific usage and function of this embodiment are as follows:

[0029] In use, when facing cement pole molds of different lengths, motor 4 is started. The output of motor 4 drives the double-headed threaded rod 3 to rotate, and plate 5 moves under the drive of the double-headed threaded rod 3, thereby adjusting the distance between the two sets of plates 5 to support the sides of the mold. Plate 2 supports the middle part of the mold. Plate 2 and plate 5 work together to provide stable support for molds of different lengths. The V-shaped design of plates 5 and 2 can provide support for cement pole molds of different sizes to a certain extent. According to the height of the cement pole mold, hydraulic cylinder 9 is started, driving frame 10 to move, thereby adjusting the height of hopper 11 and conveying pipe 13 connected to frame 10. In this way, when laying cement poles of different sizes, the conveying pipe 13 can be prevented from colliding with the mold, ensuring a smooth laying process. Concrete is poured into hopper 11, and motor 3 is started. The output of motor 3 is driven by the rod 15 to rotate. Multiple sets of spiral blades 16 connected to the rod 15 rotate accordingly. Driven by the spiral blades 16, concrete flows from the hopper 11 through the outlet 12 into the conveying pipe 13 due to gravity, and is then transported to the mold along the conveying pipe 13. The second motor 8 is started, and its output drives the threaded rod 6 to rotate. This, through the plate 7, moves the hydraulic cylinder 9, frame 10, hopper 11, and conveying pipe 13 together, allowing the conveying pipe 13 to deliver concrete to different areas inside the mold, achieving uniform distribution. After adjusting the height of the conveying pipe 13, the nut 22 is tightened to remove the restriction on the block 20. The block 20 is moved so that the wheel 19 is in contact with the worktable 1, and then the nut 22 is tightened again to press against the frame 18, fixing the wheel 19 in place. The wheel 19 enhances the stability of the conveying pipe 13 to a certain extent, ensuring the smoothness of the concrete conveying process.

Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
