Description

Technical Field

[0001] The present invention relates to the technical field of admixture processing, and specifically relates to a proportioning device for mortar concrete admixtures. Background Art

[0002] Concrete admixtures are chemical substances that are incorporated into concrete during mixing, account for less than 5% of the cement mass, and can significantly improve the performance of concrete. Concrete admixtures have the characteristics of a wide variety of types, small dosages, great influence on the performance of concrete, less investment, quick results, and significant technical and economic benefits. With the continuous progress of science and technology, admixtures have been increasingly used, and admixtures have become the fifth important component of concrete in addition to the four basic components.

[0003] When proportioning mortar concrete admixtures, it is necessary to add mortar concrete raw materials, admixtures, and water into the mixing barrel in proportion and stir evenly to form high-quality concrete. However, the traditional proportioning device for mortar concrete admixtures only rotates and stirs in the mixing barrel through a stirring shaft and stirring blades alone, and often cannot stir evenly completely, resulting in uneven mixing of the admixtures in the mortar concrete although the proportion of the admixtures is correct, thus affecting the quality of the concrete. Summary of the Invention

[0004] The purpose of the present invention is to provide a proportioning device for mortar concrete admixtures to solve the problem that the traditional proportioning device for mortar concrete admixtures only rotates and stirs in the mixing barrel through a stirring shaft and stirring blades alone, and often cannot stir evenly completely, thus affecting the quality of the concrete.

[0005] To achieve the above purpose, the present invention provides the following technical solution: A proportioning device for mortar concrete admixtures, including a base, a mixing barrel is arranged on the base, a vertical guide rod is fixedly connected to the base, a sliding block is vertically slidably arranged on the guide rod, a hydraulic cylinder is arranged between the sliding block and the base, a servo motor is fixedly installed at one end of the sliding block away from the guide rod, and further includes a self-rotation and revolution transmission mechanism and three stirring components. The self-rotation and revolution transmission mechanism is assembled to be able to convert the rotation of the output shaft of the servo motor into the self-rotation of the three stirring components and the revolution around the output shaft of the servo motor. A reciprocating transmission mechanism is arranged between the self-rotation and revolution transmission mechanism and the three stirring components. The reciprocating transmission mechanism is assembled to be able to make the three stirring components move up and down synchronously when the stirring components rotate and revolve.

[0006] Further, the rotation and revolution transmission mechanism includes an internal gear ring and a central rod. The internal gear ring is fixedly connected to the sliding block through a second bracket. The central rod is coaxially and fixedly connected to the output shaft of the servo motor and is coaxial with the internal gear ring. A V-shaped rod is fixedly connected to the circumferential side of the central rod. The two ends of the V-shaped rod far from the central rod are respectively rotatably connected to a shaft rod. A second gear is coaxially and fixedly connected to each of the two shaft rods. Both of the second gears are engaged with the internal gear ring. A first swing rod is fixedly connected to the bottom of the central rod. The end of the first swing rod far from the central rod is rotatably connected to another shaft rod. A first gear is coaxially and fixedly connected to this shaft rod. The first gear is engaged with both of the second gears. By setting the rotation and revolution transmission mechanism and cooperating with the output power of the servo motor, the three stirring components can rotate around their own axes and revolve around the output shaft of the servo motor simultaneously.

[0007] Further, the stirring component includes a tubular sleeve rod. The sleeve rod is vertically slidably connected to the shaft rod. A plurality of stirring blades are arranged on the circumferential side of the sleeve rod.

[0008] Further, convex strips are arranged on the inner wall of the sleeve rod. The sleeve rod is vertically slidably connected in the shaft rod by a manner that the convex strips cooperate with a groove opened on the shaft rod. The cooperation between the convex strips and the groove can prevent the shaft rod from rotating in the sleeve rod.

[0009] Further, the reciprocating transmission mechanism includes a cam disk and a second swing rod. The cam disk is fixedly connected to the sliding block through an L-shaped first bracket and is coaxially and rotatably connected to the central rod. One end of the second swing rod is fixedly connected to the central rod. The other end of the second swing rod is vertically slidably connected to a sliding rod. The top of the sliding rod is in sliding fit with the smooth annular concave-convex surface at the bottom of the cam disk. A disk is fixedly connected to the bottom of the sliding rod. The disk is respectively rotatably connected to the sleeve rods of the three stirring components. An elastic unit is fixedly connected between the disk and the second swing rod. The elastic unit is assembled to enable the sliding rod to always keep in a tightly pressed state with the cam disk. By setting the reciprocating transmission mechanism, when the stirring components rotate around their own axes and revolve around the output shaft of the servo motor, the three stirring components can move up and down synchronously in a reciprocating manner.

[0010] Further, the elastic unit is a tension spring.

[0011] Further, the diameter of the disk is not less than the inner diameter of the stirring barrel. The disk can prevent the liquid in the stirring barrel from splashing onto the servo motor, the rotation and revolution transmission mechanism and the reciprocating transmission mechanism during stirring.

[0012] Further, a vertical T-shaped chute is opened on one side of the guide rod. The end of the sliding block far from the servo motor is in a T shape. The sliding block is slidably arranged on the guide rod by a manner that its T-shaped end cooperates with the T-shaped chute.

[0013] Further, a discharge pipe is connected to the bottom of the stirring barrel, and a valve is provided on the discharge pipe.

[0014] Compared with the prior art, the beneficial effects of the present invention are as follows: The proportioning device for mortar concrete admixtures can make the stirring assembly rotate, revolve, and reciprocate up and down simultaneously in the stirring barrel through the cooperation among the servo motor, the rotation and revolution transmission mechanism, and the reciprocating transmission mechanism, so as to fully stir and mix the mortar concrete and the admixtures evenly, thereby improving the quality of the mortar concrete.

By setting the reciprocating transmission mechanism 9, when the stirring components 8 rotate and revolve, the three stirring components 8 can move up and down synchronously in a reciprocating manner.

[0029] Working principle: During operation, first, the hydraulic cylinder 4 is used to lift the sliding block to lift the servo motor 6, the rotation and revolution transmission mechanism 7, the reciprocating transmission mechanism 9, and the stirring components 8 above the mixing barrel 2. Then, mortar concrete raw materials, admixtures, and water in a preset ratio are added into the barrel. Then, the servo motor 6 is started to drive the central rod 702 to rotate. The central rod 702 drives the three shaft rods 706 to revolve around the central rod 702 through the first swing rod 703 and the V-shaped rod 705 respectively. At the same time, through the interaction of the two second gears 707 and the internal gear ring 701, and the interaction of the first gear 704 and the second gear 707, the three shaft rods 706 rotate, and then drive the stirring components 8 to revolve around the central rod 702 while rotating; at the same time, the central rod 702 drives the sliding rod 903 and the disc 904 to rotate around the central rod 702 through the second swing rod 902. The sliding rod 903 is always tightly pressed against the cam disc 901 under the action of the tension spring. When the sliding rod 903 rotates around the central rod 702, the top of the sliding rod 903 is in sliding contact with the smooth annular concave-convex surface at the bottom of the cam disc 901, thereby driving the disc 904 and the stirring components 8 to move up and down reciprocally. The sleeve rod 801 slides up and down reciprocally relative to the shaft rod 706. Then, the hydraulic cylinder 4 is started to make the servo motor 6, the rotation and revolution transmission mechanism 7, the reciprocating transmission mechanism 9, and the stirring components 8 slowly descend. The stirring components 8 stir while descending until they completely fall into the mixing barrel 2. The combination of the rotation, revolution, and reciprocating up and down movement of the stirring components 8 in the mixing barrel 2 can fully stir the mortar concrete and admixture ratio evenly.
