Description

Technical Field

[0001] The utility model relates to the technical field of cement mixing, and more specifically, to a cement mixer used in the construction industry. Background Art

[0002] Cement plays an irreplaceable role in the construction of modern society because it can harden in the air or in water and can firmly bond materials such as sand and stone together. Therefore, it is commonly used in various civil engineering projects, urban improvement projects, and water conservancy projects. A cement mixer is a machine that mixes and stirs cement and water.

[0003] When operators mix cement, they often use cement mixers to combine various building materials with cement and add water to mix them into concrete, thereby improving the strength and life of the building. However, in actual use, although existing cement mixers have basic mixing functions, common cement mixers can only fully mix the cement in the center part, while the surrounding cement is difficult to be fully mixed. In order to prevent this part of the cement from solidifying prematurely, operators need to stir it a second time, which increases the labor intensity of operators, and therefore they need to be improved.

[0044] The working principle and use process of this utility model:

[0045] First, the operator pours cement powder into the discharge box 18 and places the mixing barrel 30 into the placement plate 27. Then the operator starts the pneumatic cylinder 26. Due to the operation of the pneumatic cylinder 26 and the limiting of the limiting rod 28, the placement plate 27 will rise vertically to the highest point. Then the operator starts the No. 4 motor 19. Due to the operation of the No. 4 motor 19, the driving shaft 20 drives the driving gear 21 and the No. 1 roller 24 to rotate, and the driven gear 22, the driven shaft 23 and the No. 2 roller 25 rotate in the opposite direction under the meshing transmission of the driving gear 21. The rotation of the No. 1 roller 24 and the No. 2 roller 25 crushes the cement powder blocks inside the discharge box 18.

[0046] Then, the operator starts the No. 3 motor 15 and adds water into the mixing barrel 30. The operation of the No. 3 motor 15 causes the propulsion shaft 16 to drive the paddle blades 17 to rotate, so that the cement powder that falls into the pipe 14 is pushed out and falls into the mixing barrel 30. The operator then starts the No. 1 motor 4 and the No. 2 motor 10. The operation of the No. 1 motor 4 causes the No. 1 circular shaft 5 to drive the rotating rod 6 to rotate. The rotation of the rotating rod 6 causes the connecting rod 7 to pull the right end of the swing frame 8. At this time, the swing frame 8 will rotate with the top of the center plate 3 as the axis, and at this time, the sleeve 9 and the agitator 12 will swing left and right under the drive of the swing frame 8, and the operation of the No. 2 motor 10 causes the agitator shaft 11 to drive the agitator 12 to rotate. Due to the rotation and left and right swing of the agitator 12, the cement inside the mixing barrel 30 is finally fully stirred.
