[0002] In construction engineering, concrete mixing plants are the core equipment for producing concrete. Their function is to mix cement, aggregates, water, and other additives in a certain proportion to produce concrete that meets construction requirements. The lifting device of the concrete mixing plant is a key component, mainly used to transport the mixed concrete to a certain height (such as lower floors or into transport vehicles). Currently, most methods of transportation are hoisting or pump trucks, which result in high transportation costs. Therefore, a lifting device for concrete mixing plants is needed to solve the above problems. Utility Model Content

[0003] The purpose of this invention is to provide a lifting device for a concrete mixing plant. This device uses a running component to drive a conveyor belt, which uniformly transports the concrete discharged from the mixing tank to a certain height via a vertical plate. An electric telescopic rod changes the inclination angle between the guard plate and the conveyor belt, allowing the conveyor belt to transport raw materials from the mixing tank. This improves construction efficiency, reduces manual labor intensity, and lowers the cost of concrete transportation.

[0004] To achieve the above-mentioned technical objectives, the technical solution adopted by this utility model is as follows:

Detailed Implementation

[0019] To enable those skilled in the art to better understand this utility model, the technical solution of this utility model will be further described below in conjunction with the accompanying drawings and embodiments.

[0020] like Figure 1-4 As shown, the present invention discloses a lifting device for a concrete mixing plant, comprising a mobile base 1, a mixing tank 10, and a conveyor belt 11. The mixing tank 10 is fixedly installed on the upper side of the mobile base 1, and the conveyor belt 11 is installed on the upper side of the mobile base 1. Two elongated openings 12 are symmetrically distributed front and back on the upper side of the mobile base 1. A long plate 13 is slidably mounted on the lower side of the mobile base 1. A screw 14 matching the long plate 13 is rotatably mounted on the lower side of the mobile base 1. Two support plates 15 matching the elongated openings 12 are fixedly mounted on the upper side of the long plate 13. Two guard plates 16 symmetrically distributed front and back are rotatably mounted in the middle of the two support plates 15. Two drive shafts 17 are rotatably mounted on the two guard plates 16. The conveyor belt 11 is mounted on the outer side wall of the two drive shafts 17. Several vertical plates 18 linearly distributed are fixedly mounted on the outer side wall of the conveyor belt 11. Electric telescopic rods 19 are rotatably mounted on the outer side of the two support plates 15. The output ends of the electric telescopic rods 19 are hinged to the side wall of the guard plates 16. A running component matching the conveyor belt 11 is provided on the upper side of one support plate 15.

[0021] The running components include a first pulley 20 rotatably mounted on the side wall of a support plate 15, a second pulley 21 concentrically fixed on the side wall of a drive shaft 17, a belt 22 being installed between the first pulley 20 and the second pulley 21, and a material conveying motor 23 being installed on the side wall of the support plate 15, with the output shaft of the material conveying motor 23 being connected to the first pulley 20 in a transmission connection.

[0022] This utility model includes a control board, which is electrically connected to the material conveying motor 23 and the two electric telescopic rods 19, thereby facilitating operation by the user.

[0023] In the process of using this invention, when feeding materials into the mixing tank 10, the user first moves the device to the designated location using the movable base 1. Then, by rotating the screw 14, the screw 14 drives the two support plates 15 to move via the long plate 13, thereby causing the guard plate 16 and the conveyor belt 11 to move synchronously. After the left side of the conveyor belt 11 is separated from the underside of the mixing tank 1, the two electric telescopic rods 19 are activated. The output shafts of the two electric telescopic rods 19 extend, thereby driving the conveyor belt 11 to rotate via the two guard plates 16. After rotating to a certain angle, the screw 14 is rotated... The support plate 15 drives the guard plate 16 and the conveyor belt 11 to move to the left. With the help of the electric telescopic rod 19, the conveyor belt 11 is placed on the upper side of the mixing tank 10. Then the conveyor motor 23 is started. The output shaft of the conveyor motor 23 drives the drive shaft 17 to rotate through the first pulley 20, the second pulley 21 and the belt 22, thereby driving the conveyor belt 11 to rotate. The concrete raw materials are then transported into the mixing tank 1 through the conveyor belt 11 and the vertical plate 18. This eliminates the need for manual addition of raw materials into the mixing tank 10, reduces labor intensity, and increases the concrete production intensity.

[0024] In the process of using this utility model, when conveying concrete, the user operates the screw 14 and the electric telescopic rod 19 to place the guard plate 16 and the left side of the conveyor belt 11 under the mixing tank 10, and then starts the conveying motor 23, so that the concrete in the mixing tank 10 is conveyed through the conveyor belt 11 and the vertical plate 18, which makes it easier to convey the concrete in the mixing tank 10 to a certain height and improves construction efficiency.

[0025] This invention uses a running component to drive a conveyor belt, which uniformly transports the concrete discharged from the mixing tank to a certain height through a vertical plate. The tilt angle between the guard plate and the conveyor belt is changed by an electric telescopic rod, so that the conveyor belt can transport raw materials in the mixing tank, thereby improving construction efficiency, reducing manual labor intensity, and reducing concrete transportation costs.

[0026] Vertical rods 25 are fixedly provided on the lower side of the guard plate 16, and an L-shaped plate 26 is provided between the two vertical rods 25. The movable base 1 has a limiting opening 27 that matches the L-shaped plate 26.

[0027] During the use of this invention, when conveying concrete, the L-shaped plate 26 abuts against the side wall of the limiting port 27, limiting the guard plate 16 and the conveyor belt 11, reducing the stress on the electric telescopic rod 19, and extending the service life of the electric telescopic rod 19. During the use of this invention, when conveying raw materials, the L-shaped plate 26 is inserted into the upper side of the mixing tank 11, limiting the guard plate 16 and the conveyor belt 11, reducing the stress on the electric telescopic rod 19, thereby ensuring the smooth use of this device.

[0028] A protective plate 30 matching the belt 22 is fixedly provided on the side wall of the protective plate 16; to prevent debris and other objects from affecting the operation of the first pulley 20, the second pulley 21 and the belt 23, thereby ensuring the safe use of this utility model.

[0029] A guide rod 35 matching the long plate 13 is fixedly provided on the lower side of the movable base 1; it limits and guides the sliding direction of the long plate 13 to ensure the smooth operation of the device.

[0030] A handwheel 40 is concentrically fixed on the right side of the screw 14, making it convenient for the user to rotate the screw 14.

[0031] The above embodiments are merely illustrative of the principles and effects of this utility model and are not intended to limit the scope of this utility model. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of this utility model. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this utility model should still be covered by the claims of this utility model.
