Vertical shaft planet stirring machine capable of lifting materials

Abstract

The invention provides a vertical shaft planet stirring machine capable of lifting materials. The machine comprises a base, a stirring cylinder, a stirring frame and a planet stirrer; stand columns are respectively arranged at two ends of the base; guide rods are arranged on the inner sides of the stand columns; lifting motors and lifting rotating shafts are arranged on the stand columns; one ends of the lifting rotating shafts are in transmission connection with the lifting motors through transmission systems; the other ends of the lifting rotating shafts are connected with lifting cranks; two ends of the stirring frame are slidingly matched with the guide rods through slide holes; the upper sides of two ends of the stirring frame are respectively hinged to connecting rods; the other ends of the connecting rods are hinged to the lifting cranks; a stirring driving device is arranged on the upper side of the middle part of the stirring frame; the lower side of the stirring frame is connected with a rotating support; the upper end of the planet stirrer is rotationally connected to the rotating support; and the lower end of the planet stirrer extends into the stirring cylinder. The vertical shaft planet stirring machine capable of lifting materials can perform a material lifting action, and reduces a diameter-height ratio of the stirring cylinder to prevent the segregation phenomenon of stirred materials caused by higher linear velocity of stirring blades during stirring.

Description

technical field [0001] The invention belongs to the technical field of concrete mixers, in particular to a material-lifting vertical shaft planetary mixer. Background technique [0002] A mixer is a necessary equipment for preparing concrete. Vertical shaft planetary mixer is a common type of concrete mixer. It mainly realizes the forced mixing of concrete mixture through the rotation and revolution of the planetary mixing tool during work. Due to many advantages such as strong stirring effect, no stirring dead zone, and good sealing performance, the vertical shaft planetary mixer has been rapidly popularized and developed. The existing vertical shaft mixer mainly relies on the movement in the circumferential direction to achieve uniform mixing during the mixing process, and lacks the forced lifting effect in the height direction, so that the ratio of the diameter to the height of the mixing cylinder is often large, and the loading of the mixer The capacity depends on the ...

Problems solved by technology

The existing vertical shaft mixer mainly relies on the movement in the circumferential direction to achieve uniform mixing during the mixing process, and lacks the forced lifting effect in the height direction, so that the ratio of the diameter to the height of the mixing cylinder is often large, and the loading of the mixer The capacity depends on the size of the mixing cylinder, so the larger the capacity of the vertical shaft mixer with a larger ratio of diameter to height, the more significant the diameter of the mixing cylinder, which makes it difficult to transport the finished mixer, making the size of the mixer limited. limit

At the same time, the larger the diameter of the mixing cylinder, the greater the linear velocity of the mixing knife during the revolution process, resulting in greater centrifugal force on the mixture, thus increasing the risk of segregation of the mixture during the mixing process
