Description

Technical Field

[0001] The utility model relates to a new type of concrete mixing device. Background Art

[0002] Concrete mixing is an operation method of mixing materials such as cement, lime, and water evenly. Concrete mixing is divided into two types: manual mixing and mechanical mixing of water. Concrete mixing plants are widely used in construction projects such as industry, agriculture, transportation, national defense, water conservancy, and municipal administration in China, and the demand is increasing continuously.

[0003] The existing concrete mixing does not have a pre-crushing function before feeding. For some concrete raw materials with large volume and in block shape (such as limestone with large particle size), they are directly put into the mixing tank for mixing, which is not conducive to the uniform mixing process of the concrete raw materials. Moreover, these raw materials shake in the mixing tank, which will cause the mixing components inside the mixing tank to be frequently hit and prone to failure, having certain limitations.

[0004] Therefore, it is necessary to provide a new type of concrete mixing device to solve the above problems. Summary of the Utility Model

[0005] The technical problem to be solved by the utility model is to provide a new type of concrete mixing device to solve the problems raised in the above background art.

There are two crushing rollers. One end of each of the two crushing rollers penetrates out of the crushing box and is connected with a transmission gear. The two transmission gears are meshed and connected. One end of a crushing roller penetrates the crushing box and is connected with a third bevel gear. The third bevel gear is meshed and connected with the second bevel gear.

[0010] Preferably, a first protective box is arranged outside the crushing box. The two transmission gears are both located inside the first protective box. A second protective box is arranged on the top of the mixing box. The driving motor, the first bevel gear, the second bevel gear, and the third bevel gear are all located inside the second protective box.

[0011] Preferably, a collar is fixedly connected to the outer wall of the bottom of the stirring rod through bolts. Connecting rods are arranged at both ends of the collar. Scrapers are arranged at the opposite ends of the two connecting rods. The scrapers are in contact with the inner wall of the feeding hopper.

[0012] Preferably, the limiting member includes a limiting rod, a pulling block, and a return spring. The limiting rod slidably penetrates through the mixing box. The pulling block is arranged at one end of the limiting rod. The return spring is arranged between the pulling block and the mixing box. The return spring is sleeved outside the limiting rod.

[0013] Preferably, a first valve is arranged on the water inlet pipe, and a second valve is arranged on the discharging pipe.

[0014] Preferably, legs are arranged at the near corners on the four sides of the mixing box.

[0015] The beneficial effects of the present utility model are as follows: Water can be added into the mixing box through the water inlet pipe. Powdered concrete raw materials can be added into the mixing box through the feeding pipe at the front end of the mixing box. For concrete raw materials doped with larger-volume and block-shaped objects, they can be put into the crushing box, and are crushed by the crushing assembly in the crushing box, and then fall into the mixing box. The added concrete raw materials and water are stirred and mixed by the stirring assembly. The stirred concrete can be discharged through the feeding hopper and the discharging pipe. The feeding hopper can be removed through the limiting members on both sides to clean the raw materials adhered to the inner wall of the feeding hopper, avoiding the adhesion of concrete on the feeding hopper and affecting the discharging speed of the concrete.
