Cement stirring machine and feeding and discharging method thereof

Abstract

The invention discloses a cement stirring machine and a feeding and discharging method thereof. The cement stirring machine comprises a stirring frame, a stirring container, a hydraulic transmission device, a control device and a driving device, wherein the inside of the stirring container is hollow, a feeding and discharging opening is arranged at an end face of the front side of the stirring container, a supporting frame is arranged on the stirring frame to supporting the peripheral surface of the stirring container, the center of an end face of the rear end of the stirring container is in hinge connection with the hydraulic transmission device, a stirring blade is arranged on an inner wall of the stirring container, the hydraulic transmission device can drive the rear end of the stirring container to move in the vertical direction, the driving device is used for providing power for the stirring container to rotate around the axis of the stirring container, and the control device isused for controlling startup, shutdown and the rotating direction of the driving device. By means of the cement stirring machine, experimental materials can be put into and taken out conveniently, thestirred materials can reach a fully even degree, and a cement test accuracy degree is improved.

Description

technical field [0001] The invention belongs to the field of experimental instruments, and relates to a cement mixer and a material feeding and discharging method thereof. Background technique [0002] The cement paste mixer is a special instrument and equipment used in the laboratory for testing the physical properties of cement. The stirring shaft on the cement paste mixer of the prior art is fixed inside the equipment and cannot be removed. Due to the limited laboratory conditions, the mixing The container is semi-fixed on the stirring frame, and the stirring container cannot rotate by itself, but the stirring shaft rotates for stirring, because there is a gap between the stirring shaft and the inner wall of the stirring container, which leads to uneven stirring and incomplete stirring; because the stirring shaft extends into the stirring container , and the mixing blades set on it together block the inlet and outlet to a certain extent, which makes it inconvenient to put...
