Problems solved by technology

[0002] At present, most of the common concrete mixing devices on the market are divided into drum type and stirring type. The drum type mixing method mostly achieves the purpose of mixing by driving the mixing barrel to rotate. The quantity is small, and it can only mix high water-binder ratio concrete, which is not suitable for mixing viscous concrete;
[0003] Most of the stirring-type mixing methods are to install a stirring shaft that can rotate at a low speed in a fixed mixing barrel to achieve the purpose of stirring and stirring. Concrete, especially viscous concrete, has poor fluidity, and there is often a certain dead angle in the mixing process, and the overall mixing degree is poor.

Embodiment 1

[0014] see figure 1 , the present embodiment comprises a stirring tank 1, a driving box 2 is installed above the stirring tank 1, and the stirring tank 1 is a hollow cylindrical tank-shaped structure as a whole, and a stirring shaft 3 is arranged inside it. The upper end of the shaft 3 passes through the stirring tank 1 and then passes through the first bearing seat 4 installed at the bottom of the drive box 2, the driven gear column 5 and the first shaft sleeve 6 and extends out of the drive box 2. The first bearing seat 4 It can be axially slidably matched with the stirring shaft 3, the driven gear column 5 is rotationally connected with the stirring shaft 3, and the first bushing 6 and the stirring shaft 3 are axially slidably fitted through the gap of the keyway. The first axle sleeve 6 is fixed on the upper top surface of the drive box 2 through the second bearing seat 7, and one side of the first axle sleeve 6 is equipped with a driving device to drive its rotation;

Embodiment 2

[0020] First, add the proportioned ash and water into the mixing tank 1 in proportion, and then start the motor 23 and the reducer 22. During the process of driving the drive shaft 20 to rotate, the motor 23 and the reducer 22 first pass through the first driving gear. 19 and the driven gear 18 drive the stirring shaft 3 to rotate circumferentially, and the helical gear column 25 drives the helical gear 26 engaged with it to rotate during the rotation, and the helical gear 26 passes through the drive rod 28 and the connecting rod 29 during the rotation. And the driven rod 30 drives the second driving gear 31 to rotate, and the second driving gear 31 drives the driven gear column 5 engaged with it in the process of rotation to drive the stirring shaft 3 to reciprocate up and down, and the stirring shaft 3 moves up and down. During the reciprocating movement, the stirring shaft 3 and the first bushing 6 are axially slid and fitted through the gap of the key groove;

Abstract

The invention discloses concrete mixing equipment. The concrete mixing equipment comprises a mixing tank (1), wherein a drive box (2) is mounted above the mixing tank (1); the mixing tank (1) is of anintegrally hollow cylindrical tank-shaped structure, and a mixing shaft (3) is arranged inside the mixing tank (1); and the upper end of the mixing shaft (3) passes through the mixing tank (1), then,passes through a first bearing base (4) mounted on the bottom of the drive box (2), a driven gear column (5) and a first shaft sleeve (6) in sequence, and extends to the outside of the drive box (2).In a mixing process, the mixing shaft and mixing blades can be driven to move in an axial direction in a reciprocating motion mode, so that mobility inside the mixing tank is effectively improved; and meanwhile, the side mixing shafts at the two sides of the mixing shaft are in linked rotation with the mixing shaft while the mixing shaft performs mixing rotation, and the side mixing shafts mix mortar on the inner wall of the mixing tank through a rubber sheet plate in a rotation process, so that the integral mixing and stirring effect is improved.
