Aggregate conveyer of concrete station

Abstract

The invention discloses an aggregate conveying device for a concrete mixing station, comprising: a lifting track (110), a lifting bucket (130), a winch (140), a parking switch (150) and a mixer (120), and the lifting track (110) is inclined Place; the hoist (140) is positioned at the top of the hoisting track (110), connected with the hoisting bucket (130), and drives the hoisting bucket (130) to slide along the hoisting track (110), and the conveying device also includes a waiting bucket positioned above the agitator (120). The hopper (270), and the angle α between the lifting track (110) and the horizontal direction is less than or equal to 60 degrees. The present invention adds an intermediate waiting hopper to separate the working cycle of the hoist from the stirring cycle. The hoist can work continuously without waiting for the mixing time of the mixer. At the same time, the installation angle of the hoisting track is reduced, the load of the hoist is reduced, and the reliability of the hoist is improved. improve.

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
