[0048] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0049] See also Figure 1-Figure 19 A small multifunctional concrete mixing station includes a main frame 10, a mixing box 11 and an inclined belt conveyor 12 installed above the main frame 10. The main frame 10 provides a stable support structure to ensure the stability of the entire concrete mixing station and facilitate the installation of other components. The mixing box 11 is the main container for concrete mixing, which can ensure that the concrete raw materials are evenly mixed in a closed environment to prevent external pollution. A conveyor vehicle 13 is provided on one side of the mixing box 11, and an aggregate storage bin 14 is provided on one side of the inclined belt conveyor 12. The inclined belt conveyor 12 is used to transport raw materials from the aggregate storage bin 14 to the mixing box 11, reducing the labor intensity of manual handling and improving work efficiency. The conveyor vehicle 13 is used to transport the mixed concrete, which is convenient for transporting the concrete from the mixing station to the construction site. The aggregate storage bin 14 is used to store and pre-treat aggregates to ensure continuous feeding and improve production efficiency.

[0050] The power device 30 provides driving force to control the rotation of the rotating column 20, realizes the mixing and accelerated concrete discharge functions, and improves the working efficiency of the equipment. The rotating column 20 is internally connected with a screw rod 21, and the other end of the screw rod 21 is fixedly connected to the L-shaped frame 15; the outer ring of the screw rod 21 is provided with a slider 22, and the slider 22 is provided with a connecting piece 1 221 and a connecting piece 222 that penetrate the rotating column 20; when the rotating column 20 rotates, the connecting piece 1 221 and the connecting piece 222 can drive the slider 22 to rotate along the outer ring of the screw rod 21, thereby realizing the up and down movement of the slider 22 on the outer ring of the screw rod 21;

[0051] The outer ring of the rotating column 20 is provided with an annular housing 1 40 and an annular housing 2 41, and the connecting piece 1 221 is fixedly connected to the annular housing 1 40. When the slider 22 rotates, the annular housing 1 40 can be driven to rotate, and since the slider 22 moves up and down when rotating, the annular housing 1 40 will also move with the up and down movement of the slider 22;

[0052] The second connecting piece 222 is rotatably connected to the inner ring of the cross 223, and the raised portion of the cross 223 penetrates the second annular shell 41 and is slidably connected to the inner wall of the mixing box 11. When the slider 22 drives the second connecting piece 222 to rotate, the second connecting piece 222 slides on the inner ring of the cross 223 without driving the second annular shell 41 to rotate. Because the raised portion of the cross 223 penetrates the second annular shell 41 and is slidably connected to the inner wall of the mixing box 11, the second connecting piece 222 can drive the second annular shell 41 to move up and down through the cross 223;

[0053] The outer ring of the annular housing 40 is provided with a plurality of mixing structures 50. When the power device 30 drives the rotating column 20 to rotate, the rotating column 20 drives the slider 22 to rotate, and the slider 22 further drives the annular housing 40 to rotate, thereby driving the mixing structure 50 on the annular housing 40 to rotate, and the slider 22 can drive the mixing structure 50 to move up and down, thereby being able to mix concrete at different heights;

[0054] The part of the annular shell 41 located in the inner cavity of the annular shell 40 is also provided with a rotating guide groove 411, which is used in conjunction with the stirring structure 50. The rotating guide groove 411 enables the stirring structure 50 to rotate when the stirring structure 50 driven by the annular shell 40 rotates. A circular baffle 60 that can open and close automatically is arranged above the annular shell 41. When the circular baffle 60 is located at the top of the mixing box 11 and is in a closed state, the annular shell 41 drives the circular baffle 60 to descend to accelerate the discharge of concrete.

[0055] Keep watching Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5It can be seen that the mixing box 11 is located above the main frame 10, and a discharge pipe 111 is provided at the bottom of the mixing box 11. The discharge pipe 111 is used to transport the mixed concrete out of the station. A feed pipe 112 is provided at the top of the mixing box 11. The feed pipe 112 is used in conjunction with the inclined belt conveyor 12 to transport the raw materials into the mixing box 11. The top of the rotating column 20 passes through the mixing box 11, and the rotating column 20 is located in the inner cavity of the mixing box 11. The bottom of the rotating column 20 is rotatably connected to the quadrangular frame 16. The quadrangular frame 16 is fixedly connected to the bottom wall of the inner cavity of the mixing box 11. The quadrangular frame 16 ensures that the rotating column 20 maintains stable operation during the mixing process to prevent shaking or deviation, thereby improving the stability and safety of the mixing process.

[0056] Keep watching Figure 2 It can be seen that the power device 30 includes a motor 31, which is the core component of the power device 30. The motor 31 is a servo motor. The motor 31 can control the speed and position accuracy very accurately. The output end of the motor 31 is fixedly equipped with a pulley 32, and the pulley 33 is sleeved on the outer ring of the rotating column 20. The two pulleys are connected by a transmission belt 34. The motor 31 can efficiently transmit the power output by the motor 31 to the rotating column 20 through the cooperation of the pulley 32, the pulley 33 and the transmission belt 34, thereby ensuring the operation of the rotating column 20. The pulley system is simple in design and easy to install and maintain.

[0057] Keep watching Figure 3 , Figure 4 , Figure 5 , Figure 6 ,and Figure 7 It can be seen that the telescopic hose 24 is fixed to the upper and lower sides of the slider 22 and is sleeved on the outer ring of the screw rod 21. The ends of the two telescopic hoses 24 away from the slider 22 are fixedly connected to the inner cavity of the rotating column 20. The design of the telescopic hose 24 allows it to be extended and retracted as the slider 22 moves;

[0058] The existence of the telescopic hose 24 effectively prevents the concrete in the inner cavity of the mixing box 11 from contacting the screw rod 21 , thereby preventing the concrete from damaging the threads of the screw rod 21 and affecting the movement of the slider 22 .

[0059] Keep watching Figure 3 , Figure 5 , Fig. 9 , Fig.10 and Fig.11It can be seen that the stirring structure 50 includes a rectangular plate 51, which is arranged in the inner cavity of the annular shell 1 40. The rectangular plate 51 serves as a structural basis for connecting and supporting the stirring rod 53 and the sliding rod 52. The side of the rectangular plate 51 close to the annular shell 2 41 is fixedly connected to the sliding rod 52. The annular shell 2 41 is provided with a rotating guide groove 411, and the sliding rod 52 slides in the rotating guide groove 411. The side of the rectangular plate 51 away from the sliding rod 52 is provided with a stirring rod 53 that penetrates the annular shell 1 40;

[0060] The stirring rod 53 penetrates the annular shell 40. When the annular shell 40 rotates, the stirring rod 53 will also rotate with the annular shell 40. At this time, the stirring rod 53 will drive the sliding rod 52 to move in the rotating guide groove 411 through the rectangular plate 51. The rotating guide groove 411 allows the stirring rod 53 to rotate, which can more effectively stir the concrete and avoid dead corners. The connection between the rotating guide groove 411 and the sliding rod 52 is located in the inner cavity of the annular shell 40, which can effectively prevent the concrete from clogging the rotating guide groove 411.

[0061] Keep watching Figure 4 , Figure 5 and Fig.18 It can be seen that the circular baffle 60 includes a baffle 1 61 and a baffle 2 62 with openings. The bottom of the baffle 1 61 is fixedly connected to the top of the cross 223, and the baffle 2 62 is rotatably connected to the annular housing 2 41. The top of the baffle 2 62 is provided with an automatic opening and closing device 70. This design allows the baffle 2 62 to be rotated by the automatic opening and closing device 70 during mixing, so that the opening of the baffle 2 62 is connected to the opening of the baffle 1 61, thereby not blocking the passage of concrete.

[0062] The automatic opening and closing device 70 is located at the top of the baffle 2 62 and can control the rotation of the baffle 2 62. When discharging, the automatic opening and closing device 70 can make the openings of the baffle 1 61 and the baffle 2 62 misaligned, so that the baffle 2 62 blocks the opening of the baffle 1 61. As the annular shell 2 41 descends, the baffles 1 61 and the baffles 2 62 are squeezed out through the discharge pipe 111. This mechanism accelerates the discharge of the concrete.

[0063] By observation Figure 4 , Fig.14 , Fig.15 , Fig.16 , Fig.17 and Fig.19It can be seen that the automatic opening and closing device 70 includes a protective shell 71, which is sleeved on the outer ring of the rotating column 20, and a plurality of inclined blocks 72 are arranged on the side of the inner cavity of the protective shell 71 away from the rotating column 20. The bottom of the inclined block 72 is provided with a limiting column 73 that penetrates the protective shell 71, and the limiting column 73 extends to the opening of the baffle 1 61 and the baffle 2 62. The outer ring of the limiting column 73 is sleeved with a spring 74 whose two ends are respectively fixed to the protective shell 71 and the inclined block 1 72;

[0064] The top of the inclined block 1 72 is provided with an inclined block 2 75 used in conjunction with the inclined block 1 72 , and a motorized telescopic rod 1 76 fixed to the inner wall of the protective housing 71 is fixed to the side of the inclined block 25 close to the rotating column 20 ;

[0065] A second electric telescopic rod 77 is fixed to the side of the protective housing 71 away from the rotating column 20. A limit rod 78 is fixed to the output end of the second electric telescopic rod 77. The limit rod 78 penetrates the protective housing 71 and is engaged with the rotating column 20. The protective housing 71 has a space for installing a rechargeable battery. The rechargeable battery can provide power for the first electric telescopic rod 76 and the second electric telescopic rod 77.

[0066] By manipulating the electric telescopic rod 2 77, the limit rod 78 can be driven to move toward the rotating column 20, so that the limit rod 78 is engaged with or separated from the rotating column 20. When the limit rod 78 is engaged with the rotating column 20, the rotating column 20 can drive the protective housing 71 to rotate through the limit rod 78. In addition, the protective housing 71 is also equipped with an electric telescopic rod 1 76, which can push the inclined block 2 75 to move toward the inclined block 1 72. By controlling the inclined block 2 75 to move closer to or away from the inclined block 1 72, the distance that the limit rod 73 extends toward the opening of the baffle 1 61 and the baffle 2 62 can be adjusted, thereby adjusting or fixing the position of the baffle 2 62.

[0067] When the limiting column 73 extends to the opening of the baffle 2 62, the protective shell 71 can drive the baffle 2 62 to rotate and adjust the positions of the openings of the baffle 1 61 and the baffle 2 62; when the limiting column 73 passes through the opening of the baffle 2 62 and extends to the opening of the baffle 1 61, it can fix the position of the baffle 2 62 so that the baffle 2 62 stops rotating.

[0068] The use process of the present invention:

[0069] 1. The motor 31 transmits power to the rotating column 20 through the pulley 1 32, the pulley 2 33 and the transmission belt 34. The rotating column 20 drives the internal slider 22 to rotate. While the slider 22 rotates, it moves up and down on the outer ring of the screw rod 21;

[0070] 2. The rotation of the slider 22 drives the annular housing 1 40 and the annular housing 2 41 through the connecting member 1 221 and the connecting member 2 222 respectively. The annular housing 1 40 can both rotate and move up and down, while the annular housing 2 41 can only move up and down;

[0071] 3. The annular housing 1 40 drives the multiple stirring structures 50 to move up and down in the inner cavity of the stirring box 11. At the same time, the annular housing 1 40 drives the stirring structures 50 to rotate around the annular housing 2 41. At this time, the slide bar 52 closest to the rotating guide groove 411 is guided to the rotating guide groove 411. The rotating guide groove 411 is similar to a triangular slide groove. When the slide bar 52 moves toward the center of the rotating guide groove 411, the rectangular plate 51 connected to the slide bar 52 and the slide bar 52 away from the rotating guide groove 411 will rotate in the rotation direction of the annular housing 1 40;

[0072] 4. There is a square groove at the center top of the rotating guide groove 411. When the slide bar 52 enters the square groove, the rectangular plate 51 will continue to rotate with the slide bar 52 as the center, and drive the slide bar 52 away from the rotating guide groove 411 to continue to rotate along the rotation direction of the annular housing 40. After rotating a certain angle, the annular housing 40 will drive the slide bar 52 in the square groove to move along the other half of the rotating guide groove 411.

[0073] 5. At this time, the slide bar 52 away from the rotating guide groove 411 will move in front of the slide bar 52 that originally moved in the rotating guide groove 411. In the process of the slide bar 52 entering and leaving the rotating guide groove 411, the stirring rod 53 completes one rotation;

[0074] 6. When the mixing is completed, the automatic opening and closing device 70 is activated, and the electric telescopic rod 2 77 drives the limit rod 78 to engage with the rotating column 20, and the rotating column 20 drives the baffle 2 62 fixed to the protective housing 71 to rotate. When the baffle 2 62 can block the opening of the baffle 1 61, the rotation stops, and the electric telescopic rod 2 77 drives the limit rod 78 to release the engagement with the rotating column 20;

[0075] 7. The electric telescopic rod 1 76 drives the inclined block 2 75 to move, and the inclined block 2 75 squeezes the inclined block 1 72 and the limiting column 73 fixed to the inclined block 1 72. The limiting column 73 passes through the openings of the baffle 1 61 and the baffle 2 62 to limit the rotation of the baffle 2 62;

[0076] 8. At this time, the baffle plate 1 61 and the baffle plate 2 62 move downward through the annular housing 2 41 to squeeze the concrete toward the discharge pipe 111, thereby accelerating the discharge of the concrete.

[0077] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto.
