Description

Technical Field

[0001] The utility model belongs to the technical field of concrete production and processing equipment, and particularly relates to a concrete mixing device for a laboratory. Background Art

[0002] Laboratory concrete mixing is the process of preparing concrete samples under controlled conditions. Mixing typically involves combining cement, aggregates, water, and admixtures in defined proportions to ensure uniformity and consistency. The mixing process is crucial for testing concrete properties in the laboratory, researching new materials, or optimizing concrete formulations.

[0003] In the prior art, laboratory concrete mixing is usually carried out using a small mixer to precisely control the material ratio and mixing time.

[0004] However, after the mixing is completed, it is difficult to remove all the samples in the mixing tank of the existing laboratory concrete mixer during discharge. The sample residue is easy to clump in the mixing tank, affecting the discharge volume and making it difficult to clean. Utility Model Content

[0005] In order to solve the above problems in the prior art, the purpose of the present invention is to provide a laboratory concrete mixing device with easy material removal.

[0006] In order to achieve the above technical objectives, the present invention adopts the following technical solutions:

[0007] A laboratory concrete mixing device includes a mixing tank, a mixing device, a limit device, a motor, a control box, and a base. The mixing tank is installed on a roller shaft of the base, and both ends of the roller shaft are installed on the base through bearings. The mixing device is installed inside the mixing tank. A limit groove is provided on the outer end surface of the mixing tank, and the limit device is installed corresponding to the limit groove. The power input end of the mixing device is connected to the power input end of the motor, and the motor is installed inside the control box. The control box is installed on the base.

[0008] Furthermore, one side of the discharge port of the mixing tank is set as a confluence port, a limit groove is opened on the outer end face of the tank, and limit holes are provided in the limit groove at positions corresponding to the stirring position and pouring position of the mixing tank, and a rotating handle is installed on the side wall.

[0009] Furthermore, the limiting device includes a pedal, a limiting pin, and a spring. The pedal can be rotated on the base through a bolt. One end of the limiting pin is connected to the notch at the upper end of the pedal, and the other end is connected to the limiting slot. One end of the spring is connected to the pedal, and the other end is linked to the base.

[0010] Furthermore, the stirring device includes a stirring shaft and a stirring blade, one end of the stirring shaft is connected to the motor, and the other end is connected to the base through a bearing.

[0011] According to the above technical solution, the beneficial effect of the present invention is that the amount of concrete used in the laboratory is relatively small. The present invention enables the mixing tank to rotate axially to pour out the concrete material in the tank, making it convenient to take out all the materials, avoiding a small amount of material from accumulating inside the mixing tank, and making the entire device easy to clean and maintain.
