Planetary vertical-shaft concrete stirrer

Abstract

The invention relates to a concrete vertical shaft planetary mixer, which includes a motor speed reducer arranged on the top of the mixer. More than one motor speed reducer is arranged in a planetary form within the circle diameter of the top of the mixer. A central feeding device with a central feeding port is provided in the central area of ​​the top, and more than one motor reducer is placed on the outer ring of the central feeding port. The rotary mechanism of the motor reducer is connected with the stirring arm, and more than one set of stirring arms together with the stirring shovel are installed in the stirring chamber. The electric motor reduction box on the mixer of the present invention saves power consumption and reduces the production cost of concrete mixing. With the central feeding device located in the central area of ​​the mixer top of the present invention, after materials such as sand, gravel and cement are thrown into the inner cavity of the mixer from the central feeding port, they can be quickly diffused to the surroundings under the action of stirring and evenly distributed on the bottom of the inner cavity of the mixer. This greatly shortens the mixing time, saves power consumption, increases the uniformity of concrete, and helps to improve the compressive strength and stability of concrete.

Description

technical field [0001] The invention relates to cement concrete production equipment, in particular to a concrete vertical shaft planetary mixer. Background technique [0002] Existing concrete vertical shaft mixers all use a single motor gearbox, which is placed on the top of the center of the mixer. Since the radius from the center of the top to the outer edge is relatively long, a large torque is required to drive the mixer. Obviously, the motor gearbox The layout is unreasonable. Also, there is no way to restart the mixer with a full load, eg 2m mixing capacity 3 High-end concrete mixers require up to 75kW of motor power, resulting in a single motor with high power and high power consumption, which increases the production cost of concrete mixing. [0003] When the concrete mixer is working, since the motor reducer is located at the top of the mixer, when sand, cement and other materials are put into the mixer, they can only be put in from the side of the machine. Thi...
