Skeletal material conveyer of concrete station

Abstract

The invention discloses an aggregate convey device adopted by a concrete mixing station and comprises a lift rail (110), a lift bucket (130), a hoister (140), a shutdown switch (150) and a mixer. The lift rail (110) is placed aslant; the hoister (140) is at the top end of the lift rail (110) and connected with the lift bucket (130) to drive the lift bucket (130) to slide along the lift rail (110). The convey device also comprises a material storage bucket (270) which is arranged above the mixer (120) and the angle Alfa between the lift rail (110) and the level is less than or equal to 60 degrees. The material storage bucket is added in the invention, which separates the working circulation of a lifter and the mixing circulation and enables the lifter to work continuously and meanwhile, reduces the installation angle of the lift rail and the loading of the hoister, thus improving the reliability of the hoister.

Description

technical field [0001] The invention relates to the field of concrete production, in particular to an aggregate conveying device for a concrete mixing station. Background technique [0002] At present, there are mainly two conveying methods for the aggregate transportation of concrete mixing plants, one is conveyed by belt conveyor, and the other is conveyed by rail hoist. [0003] Belt conveyors are widely used because of their stable and reliable operation. However, the transmission transmission inclination angle α of the belt conveyor is generally small, the maximum inclination angle α of the flat belt is 20 degrees, and the maximum inclination angle α of the herringbone belt is 29 degrees. Because the inclination angle is small, the installation length dimension L of the belt conveyor is large. [0004] Therefore, the mixing plant that adopts belt conveyor generally covers a large area and has many parts, which is inconvenient for installation, transportation, and relo...

Problems solved by technology

In order to improve efficiency, the method of increasing the inclination angle α of the hoist is adopted to shorten the actual running distance of the hoist bucket. At present, the inclination angle α of the hoist used in the mixing station is greater than 60 degrees, but increasing the inclination angle α will increase the wire tension of the hoist Increase the load. When the lifting speed is constant, the power and torque of the motor must be increased when the load increases. The increase in power will increase the energy consumption.

[0007] Therefore, the main problem in this rail hoist conveying method is: due to the large inclination of the rail, the torque is relatively large, which reduces the reliability of the hoist

[0008] In addition, due to the increased size of the motor gearbox, and thus increased manufacturing costs

[0009] Moreover, because the hoist sends a signal through the induction stop switch 150 when the hoist is in the loading and unloading position, the instantaneous forced braking under the moving speed when the hoist bucket 130 descends brings a big impact to the hoisting machine 140, which not only reduces the The life of the brake, but also a large impact load on the gearbox gear
