DETAILED DESCRIPTION

[0020] The utility model is further described below in combination with examples.

[0021] Please refer to Figures 1-4 The utility model provides a concrete feeding device, including feeding cylinder 1, rotating rod 2 is connected between the both ends of feeding cylinder 1, and the outside wall of rotating rod 2 is fastened and is connected with spiral feeding blade 3, and one end of feeding cylinder 1 is fixed with driving motor 4, and driving motor 4 is coaxially connected between rotating rod 2, and the top of feeding cylinder 1 is communicated with feeding hopper 5, and the bottom of feeding cylinder 1 is communicated with discharge pipe 6, and the inside of discharge pipe 6 is provided with dredging assembly 7, and the below of feeding cylinder 1 is provided with base 8, and the top of base 8 is fixed with two symmetrical rotating seats 9, and two rotating seats 9 are rotatably connected with the outside wall of feeding cylinder 1, and the top of base 8 is provided with adjusting assembly 10;Driving motor 4 can also drive dredging assembly 7 to dredge the inside of discharge pipe 6 when rotating, avoids the inside of discharge pipe 6 to pile up, makes the discharge more smooth.

[0022] Further details are worth noting: the guiding component 7 includes a mounting bracket 71 fixed to the top of the conveying cylinder 1. A rotating shaft 72 is rotatably connected to one side wall of the mounting bracket 71. A half-gear 73 is fixed to the outer side wall of the rotating shaft 72. A toothed ring 74 is sleeved on the outer side wall of the half-gear 73. The toothed ring 74 is slidably connected to the inner walls of both sides of the mounting bracket 71. A lifting rod 75 is fixed to the bottom end of the toothed ring 74. The bottom end of the lifting rod 75 slides through the top of the conveying cylinder 1. A movable ring 76 is fixed to the bottom end of the lifting rod 75. The movable ring 76 is sleeved on the outside of the rotating shaft 72. A guide rod 77 is fixed to the bottom of the discharge pipe 6. Multiple connecting rods 78 arranged in a ring are fixed to the outer wall of the guide rod 77. A first pulley 79 is fixed to one end of the rotating shaft 72. A second pulley 710 is fixed to one end of the rotating rod 2 through the outside of the material conveying cylinder 1. A transmission belt 711 is sleeved between the first pulley 79 and the second pulley 710. The rotating shaft 72 is driven to rotate by the rotating rod 2, which enables the half gear 73 to cooperate with the rack plate 11 to drive the guide rod 77 and connecting rods 78 to move up and down to convey material to the discharge pipe 6, avoiding material blockage and ensuring construction efficiency.

[0023] It is worth further explaining that the adjustment component 10 includes a mounting groove 101 opened at the top of the base 8, a movable plate 102 slidably connected between the two side walls of the mounting groove 101, and two symmetrically arranged support rods 103 hinged between the top of the movable plate 102 and the conveying cylinder 1. A telescopic cylinder 104 is fixed to one side wall of the mounting groove 101, and the output end of the telescopic cylinder 104 is fixed to the movable plate 102. The height of the end of the conveying cylinder 1 near the discharge pipe 6 can be adjusted by the adjustment component 10, which is convenient for conveying materials at different heights and has good applicability.

[0024] This solution includes the following working process: When concrete needs to be conveyed, it is unloaded into the feed hopper 5, and then the drive motor 4 is started. The drive motor 4 drives the rotating rod 2 to rotate, which in turn drives the spiral feeder 3 to rotate. As the spiral feeder 3 rotates, the concrete is conveyed from one end of the conveying cylinder 1 to the other end and discharged through the discharge pipe 6. The operator receives the concrete at the discharge pipe 6. Simultaneously, the rotating rod 2 drives the first pulley 79 to rotate. The rotation of the first pulley 79 drives the second pulley 710 to rotate via the transmission belt 711. The rotation of the second pulley 710 drives the mixing rod 12 inside the feed hopper 5 to rotate, thus mixing the concrete and preventing it from clumping or separating, ensuring the concrete... The mixture is relatively uniform. As the rotating rod 2 rotates, it drives the half gear 73 to mesh with the two rack plates 11 inside the toothed ring 74 in sequence. This drives the toothed ring 74 to move up and down. When the toothed ring 74 moves up and down, it drives the lifting rod 75 and the moving ring 76 to move up and down. When the moving ring 76 moves, it drives the guiding rod 77 and the connecting rod 78 to guide the discharge pipe 6, avoiding blockage during discharge and making the concrete delivery smoother, thus ensuring construction efficiency. When it is necessary to adjust the discharge height of the discharge pipe 6, the moving plate 102 is moved by the telescopic cylinder 104. When the moving plate 102 moves, it works with the support rod 103 to raise or lower one end of the conveying cylinder 1, making it convenient for conveying materials at different heights.

[0025] As can be seen from the above working process: while driving the rotating rod 2 and the spiral feeding blade 3 to rotate and transport concrete, the driving motor 4 can also drive the mixing rod 12 to mix the concrete in the feed hopper 5, making the concrete more uniform and avoiding stratification and clumping. While the driving motor 4 is rotating, it can also drive the guiding component 7 to guide the discharge pipe 6 to avoid blockage inside the discharge pipe 6 and make the discharge smoother.

[0026] It is worth further explaining that rack plates 11 are provided on both sides of the inner wall of the toothed ring 74, and the half gear 73 meshes with one of the rack plates 11.

[0027] It is worth further explaining that one end of the rotating rod 2 passes through the feed hopper 5, and multiple equidistant mixing rods 12 are fixed on the outer wall of the rotating rod 2. The mixing rods 12 are located inside the feed hopper 5. The rotating rod 2 and the spiral feeding blade 3 are driven by the drive motor 4 to rotate and transport the concrete. At the same time, the mixing rods 12 can also drive the mixing rods 12 to mix the concrete in the feed hopper 5, so that the concrete is mixed more evenly and avoids stratification and clumping.

[0028] It is worth further elaborating that the multiple connecting rods 78 and the guide rods 77 are arranged at an angle, and the multiple connecting rods 78 and the guide rods 77 are arranged in a claw shape.

[0029] In summary: By rotating the shaft 72 through the rotating rod 2, the half gear 73, in conjunction with the rack plate 11, drives the guide rod 77 and the connecting rod 78 to move up and down to convey material to the discharge pipe 6, avoiding material blockage and ensuring construction efficiency. The height of the end of the conveying cylinder 1 near the discharge pipe 6 can be adjusted by the adjusting component 10, which is convenient for conveying material to work positions at different heights and has good applicability.

[0030] The drive motor 4 can be purchased from the market. The drive motor 4 is equipped with a power supply. It is a mature technology in this field and has been fully disclosed. Therefore, it will not be described again in the specification.
