[0001] The invention belongs to the technical field of concrete processing, and more specifically, particularly relates to a premixing device for concrete processing. Background Art

[0002] Premixing equipment for concrete processing is a key device in concrete production. It is mainly used to premix various raw materials such as cement, sand, stone, admixtures, etc. in a certain proportion. The equipment generally includes a mixing host, which fully mixes the materials through the rotation of the mixing shaft and blades to make the components evenly distributed, which helps to improve the quality of concrete.

At this time, the two springs are in a compressed state, and the two limit blocks pass through the fixed bottom plate.

This stable meshing transmission structure effectively reduces the energy loss and mechanical wear caused by shaking or misalignment of the transmission parts, which not only prolongs the service life of the equipment, reduces the maintenance frequency and cost, but also ensures the high efficiency and stability of power transmission.

[0022] In the present invention, by providing a second fixing ring, when the motor is started, the second fixing ring can stably limit the motor, thereby avoiding position deviation caused by vibration of the motor during startup, reducing the risk of transmission failure caused by displacement, ensuring accurate and continuous power transmission, and facilitating the efficient and orderly implementation of the concrete premixing process.

The rotating bevel gear 32 drives the meshing bevel gear 30 and the front end connecting short rod 1 28 to rotate. Since the two connecting short rods 1 28 are connected through the driving sprocket 25 and the driven sprocket 34 The two connecting short rods 28 are engaged with the synchronous chain 27, so that the two connecting short rods 28 will drive the threaded rod 14 to rotate synchronously.

[0049] Working principle:

[0050] In the first step, the user puts the concrete raw material into the fixed frame 19, presses the fixed frame 19 between the lifting blocks 16, and the two springs 22 are in a compressed state. The two limit blocks 20 are passed through the fixed bottom plate 23. At this time, the two limit blocks 20 will resist the fixed frame 19 to prevent the two springs 22 from pushing the fixed frame 19 to rebound. The motor 26 is started, and the motor 26 drives the connecting short rod 23 and the rotating bevel gear 32 to rotate.

When the limit blocks 20 rise to a certain distance, the lower ends of the two limit blocks 20 will abut against the edge of the fixed ring 12, so that the limit blocks 20 will not continue to rise. At this time, the fixed bottom plate 23 continues to drive the fixed frame 19 to rise until the limit blocks 20 no longer abut against the fixed frame 19. The two springs 22 rebound and push the fixed frame 19. When the fixed frame 19 moves, the concrete raw materials in the fixed frame 19 will be pushed out, thereby achieving the purpose of automatic loading.

[0052] In the third step, when the spring 22 pushes the fixed frame 19, the two connecting columns 21 will move with the movement of the fixed frame 19. The two connecting columns 21 are socketed with the connecting plate 18.
