Electromagnetically fixed and anti-loosening cement mortar stirring device

Abstract

The invention discloses an electromagnetically fixed and anti-loosening cement mortar stirring device and relates to the technical field of cement stirring. The device comprises a base, the inner bottom wall of the base is fixedly connected with an electromagnetic device I, and the inner wall of the right side of the base is fixedly connected with a piezoresistor electrically connected with the electromagnetic device I. According to the electromagnetically fixed and anti-loosening cement mortar stirring device, the electromagnetic device I and a dielectric plate are matched for use, when a clamping seat of a stirring barrel is placed in a mounting groove, a movable block contracts downwards under the action of the gravity of the stirring barrel, the dielectric plate reduces the relative area of a positive electrode and a negative electrode, the voltage of the circuit is smaller than the maximum path voltage of the piezoresistor, at the moment, a circuit of the electromagnetic device Iis connected, the movable block is contracted into the base under the magnetic attraction effect of the electromagnetic device I and the magnetic ring, the electromagnetic device I and a second magnetic block in the clamping base are magnetically attracted, the stirring barrel is tightly fixed to the base, and therefore the electromagnetic fixing effect is achieved, and the stirring barrel is effectively prevented from loosening.

Description

technical field [0001] The invention relates to the technical field of cement mixing, in particular to an electromagnetically fixed and loose-proof cement mortar mixing device. Background technique [0002] The cement mortar mixing device in the laboratory is mainly used to mix the cement evenly, so that the ingredients of the cement are mixed more uniformly, which is convenient to improve the accuracy of the cement experiment data, and the use of the cement mortar mixing device can effectively improve the experimental efficiency and speed up the experiment. process. [0003] When the current cement mortar mixing device is in use, most of the mixing barrel is clamped with the machine body. The clamping connection method will easily lead to loosening of the mixing barrel, resulting in cement spilling, affecting the experiment process, and the stirring rod will be in contact with the inner wall of the mixing barrel. The collision will cause damage to the mixing tank, resultin...

Problems solved by technology

[0003] When the current cement mortar mixing device is in use, most of the mixing barrel is clamped with the machine body. The clamping connection method will easily lead to loosening of the mixing barrel, resulting in cement spilling, affecting the experiment process, and the stirring rod will be in contact with the inner wall of the mixing barrel. Collision, causing damage to the mixing tank, resulting in loss of experimental equipment, increasing the cost of the experiment, and the loosening of the mixing tank may accidentally injure the experimenter, resulting in an experimental accident, which is very dangerous
