[0022] As shown in Figures 1-2 The bottom of the fixed frame 2 is provided with a moving wheel 3, here, the design of the moving wheel 3 enables workers to freely move the device according to actual needs, effectively improves the mobility of the device, and provides convenience for workers.
[0023] As shown in Figure 1 The bottom of the conveyor shell 11 is provided with a moving seat 6, the top of the moving seat 6 is provided with a cylinder 7, the piston rod of the cylinder 7 is rotatably connected with the conveyor shell 11, here, the cylinder 7 is started, the piston rod of the cylinder 7 performs piston movement, and the piston rod of the cylinder 7 drives the conveyor shell 11 to rotate around the axis of the rotating seat 4 to adapt to the feeding requirements of the solid additive in different production scenarios and improve the flexibility of the device.
[0024] As shown in Figures 1-2 The hopper 1 is fixedly connected with a blocking rod 14 for screening additives, here, the design of the blocking rod 14 can screen the solid additive when the worker adds the solid additive, prevent the damp and caked solid additive from entering the device, avoid the caked solid additive from being conveyed to the concrete mixing equipment through the device, and thus reduce the problem of uneven mixing.
[0025] As shown in Figure 2As shown, the folding sleeve 5 is in a multi-layer folded structure, and each layer of the folding sleeve 5 is nested with each other, and the folding sleeve 5 can be stretched and folded under stress. Here, the folding sleeve 5 is designed to have good expansion performance, which can adapt to the change of the angle adjustment of the conveyor shell 11 through its own deformation, thereby ensuring the sealing of the solid additive in movement.
[0026] The device is used to deliver solid additives to the concrete mixing equipment when it is working. When in use, the motor 8 is started, the motor 8 drives the output shaft to rotate, the output shaft of the motor 8 drives the connected rotating shaft 12 to rotate, and then drives the spiral blade 13 on the rotating shaft 12 to rotate. Then, a proper amount of solid additives is poured into the hopper 1, and the solid additives fall downward under the influence of their own gravity after entering the hopper 1, so that the solid additives pass through the hopper 1 and the folding sleeve 5 and enter the feeding port 9 of the conveyor shell 11. After the solid additives enter the inside of the conveyor shell 11, the spiral blade 13 extrudes and pushes the solid additives, so that the solid additives move from the feeding port 9 to the discharging port 10. When the solid additives enter the feeding port 9, the smaller diameter of the rotating shaft 12 can provide more space for the solid additives to receive a large amount of solid additives. At the same time, the smaller pitch of the spiral blade 13 means that the distance that the solid additives are pushed forward by the spiral blade 13 is shorter when the rotating shaft 12 rotates one revolution, but the contact area between the spiral blade 13 and the solid additives in unit length is relatively larger, so that a larger thrust can be generated to quickly guide a large amount of concrete into the inside of the conveyor. As the solid additives move to the discharging port 10, the pitch of the spiral blade 13 and the diameter of the rotating shaft 12 gradually increase, so that the distance between the adjacent two blades of the spiral blade 13 gradually increases during the advancement of the solid additives, and the space occupied by the material also increases. At the same time, the diameter of the rotating shaft 12 gradually increases, resulting in that the extrusion force of the solid additives from the spiral blade 13 and the cylinder wall gradually increases during the conveying process, so that the solid additives in unit length at the feeding port 9 deform when moving to the discharging port 10, effectively preventing the solid additives from being compacted due to their own weight. Finally, the solid additives fall into the concrete mixing equipment from the discharging port 10.
[0027] Although the present disclosure has been described only with respect to a limited number of embodiments, those skilled in the art who benefit from the present disclosure will understand that various other embodiments can be designed without departing from the scope of the present utility model. Therefore, the scope of the present utility model should be limited only by the appended claims.
