Embodiment Construction

[0056] The technical solutions of the present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0057] refer to figure 1 1. During the reclaiming operation of the stacker-reclaimer 10, the rotational speed of the bucket wheel 11 itself is constant, and the speed of the rotary mechanism 14 is adjustable. The faster the revolving speed, the higher the reclaiming capacity of the bucket wheel 11. The higher the amount of material taken, the greater the current of the bucket wheel motor that drives the bucket wheel 11 to rotate itself.

[0058] In the present invention, the current value of the bucket wheel motor of the stacker reclaimer 10 is sampled, and a corresponding functional relationship is established with the actual bucket wheel reclaiming amount and the frequency and speed of the rotary motor that drives the rotary mechanism 14 to rotate. In the control, the current of the bucket wheel motor is used as a negative ...

Abstract

The invention discloses an automatic material taking control device and a method of a material piling and taking machine. Because the invention has a function of collecting the current of a motor of a bucket wheel, establishes a relational model between the current of the motor of the bucket wheel and the material taking amount of the bucket wheel, and establishes a relational model between the material taking amount of the bucket wheel and the frequency of a rotary motor of a cantilever, under the action of the relational models, the rotary speed of the cantilever can be determined by the frequency of the rotary motor of the cantilever and can be controlled by the current of the motor of the bucket wheel in the automatic material taking process, and the current of the motor of the bucket wheel can accurately and quickly reflect the material taking amount of the bucket wheel, thereby effectively forming a closed loop control process to well control the material taking amount of the bucket wheel. In addition, because the invention has a function of judging the material pile boundary, when each material taking process reaches the material pile boundary, the invention can carry out judgment automatically and adjust the position of the material piling and taking machine to carry out the rotary material taking process for the next time, and the processes are carried out repeatedly and circularly to automatically complete the material taking process of the whole material pile, thereby realizing unmanned operation.

Description

technical field [0001] The invention relates to the field of stackers and reclaimers, more specifically, to an automatic reclaiming control device and method for a stacker and reclaimer. Background technique [0002] In large-scale iron and steel complexes and large ore terminals, the large demand for raw materials (ore, coal, etc.) has created a huge storage yard, which requires a large number of stacking and reclaiming equipment for production, and at the same time, a large number of operating drivers are required. operate these devices. [0003] At present, bucket wheel stackers and reclaimers are mainly used in domestic and foreign storage yards for stacking and reclaiming operations. The working diagram of the existing bucket-wheel stacker-reclaimer is as follows: figure 1 shown. In the stacker-reclaimer 10, the cart mechanism 15 is equipped with a rotary mechanism 14, the rotary mechanism 14 is provided with a cantilever 13, and one end of the cantilever 13 is provi...
