Description

Technical Field

[0001] The utility model relates to the technical field of concrete mixing, in particular to a concrete compound mixer. Background Art

[0002] Concrete, referred to as "concrete", is a general term for engineering composite materials that are cemented into a whole by cementitious materials. The term concrete usually refers to a mixture of materials such as aggregates, cement and water. After mixing and hardening, it can be used in construction, roads, bridges and other projects. Concrete has the advantages of high compressive strength, good durability and a wide range of strength grades. It is one of the most widely used building materials in modern construction. The production of concrete requires strict mix design, the selection of high-quality raw materials, and mixing, transportation, pouring, maintenance and other links according to the prescribed process to ensure its quality and performance.

[0003] The existing concrete mixing process is carried out inside a mixing drum, which is usually placed tilted or horizontally. The motor drives the spiral stirring blades inside the mixing drum to rotate, and the aggregate, cement, water and other materials put into the mixing drum are mixed and stirred to make concrete.

[0004] Most existing concrete mixers still utilize the friction between concrete and the mixing blades and the gravity of concrete to mix the concrete. However, when the viscosity between some concrete raw materials is large, concrete lumps are easily formed, and the mixing blades are not easy to disperse these lumped concretes well, resulting in low concrete quality. In view of this, the present application proposes a concrete compound mixer. Utility Model Content

[0008] The present application adopts the above technical solution, and drives the dispersion shaft to rotate through the dispersion motor, drives the dispersion blades to rotate, breaks up the agglomerated concrete in the mixing tank, prevents the concrete from agglomerating, and increases the quality of the concrete.

[0009] Furthermore, a stirring assembly is fixedly mounted on the bottom of the rotating head, and a stirring motor whose output end is fixedly connected to the top of the rotating shaft is fixedly mounted on the bottom of the mounting shell.

[0010] The beneficial effect of adopting the above further solution is: the stirring motor drives the rotating shaft to rotate, drives the rotating head to rotate, and provides stirring power for the stirring component.

[0011] Furthermore, the stirring assembly includes a stirring shaft fixedly mounted on the bottom of the rotating head and a stirring blade fixedly mounted on the surface of the stirring shaft.

[0012] The beneficial effect of adopting the above further solution is that the stirring shaft rotates with the rotating head, driving the stirring blades to stir the concrete in the stirring tank, so that the concrete raw materials are quickly mixed to form concrete.

[0013] Furthermore, a rotation component for driving the stirring kettle to rotate is arranged inside the mounting shell.

[0014] The beneficial effect of adopting the above further solution is: the self-rotating component drives the mixing kettle to rotate in the opposite direction of the rotating shaft, thereby increasing the mixing speed of the concrete raw materials and the mixing efficiency.

[0015] Furthermore, the self-rotating assembly includes a worm wheel fixedly mounted on the surface of the rotating support tube, a worm rotatably mounted on the inner side wall of the mounting shell and meshing with the worm wheel, and a self-rotating motor fixedly mounted on the surface of the mounting shell for driving the worm wheel to rotate.

[0016] The beneficial effect of adopting the above further solution is that the self-rotating motor drives the worm to rotate, drives the worm wheel to rotate, drives the rotating support tube to rotate, and thus drives the stirring kettle to rotate in the opposite direction of the rotating shaft.

[0017] Furthermore, an output pipe is fixedly installed at the bottom of the stirring kettle, an electric-controlled discharge valve is fixedly installed on the surface of the output pipe, and the bottom end of the output pipe extends to the outside of the installation shell.

[0018] The beneficial effect of adopting the above further solution is that after the concrete is prepared, it is discharged to the bottom of the installation shell through the output pipe, which is convenient for use.

[0019] Furthermore, a plurality of feed pipes are fixedly mounted on the surface of the mounting shell, and one end of the feed pipe extends to the top of the stirring tank.

[0020] The beneficial effect of adopting the above further solution is that materials such as aggregate, cement and water are added into the interior of the stirring tank through the feeding pipe and stirred.

[0021] Furthermore, a leg is fixedly mounted on the bottom of the mounting shell, and a support plate is fixedly mounted on the bottom of the leg.

[0022] The beneficial effect of adopting the above further solution is: the mounting shell is supported by the legs, and the contact area between the legs and the ground is expanded by the support plates, thereby increasing the support stability.

[0024] 1. The concrete compound mixer is provided with a dispersing component on the rotating head, and the dispersing blades are driven to rotate by the dispersing motor. At the same time, the stirring motor drives the rotating head to rotate, and drives the dispersing blades to rotate at different positions in the mixing tank to break up the concrete lumps in the mixing tank. This solves the problem that when the viscosity between some concrete raw materials is large, concrete lumps are easily formed, and the stirring blades are not easy to disperse these lumps of concrete well, resulting in low concrete quality. The concrete lumps are broken up by the dispersing blades, so that the quality of the concrete is improved.

[0025] 2. The concrete compound mixer is provided with a rotation component inside the mounting shell to drive the mixing kettle to rotate. The rotation motor drives the worm to rotate, and drives the worm wheel to rotate, so that the rotating support pipe rotates, and the mixing kettle rotates. The direction of rotation of the mixing kettle is opposite to the direction of rotation of the rotating shaft, thereby increasing the speed at which the dispersing blades and the mixing blades contact the concrete, and increasing the concrete mixing effect.
