Dynamic correcting crawler

Abstract

The invention discloses a dynamic correcting crawler. The dynamic correcting crawler is characterized in the a detecting unit is arranged, the side edges of a crawler belt are detected, and limit detecting signals are output when the positions of the side edges of the crawler belt locate in limiting positions; an adjusting unit is arranged, a cylinder is fixedly arranged on a frame side plate of a crawler frame, the piston rod of the cylinder acts on the shaft end of a roller cylinder by pushing forwardly or pulling backwardly, and accordingly the the rolling cylinder is driven by the piston rod of the cylinder at the shaft end so as to adjust the included angle of the axis of the rolling cylinder and the central line of the crawler belt; the limit detecting signals output by the detecting unit serve as control signals adjusting the actions of the piston rod of the cylinder of the adjusting unit, and the piston rod of the cylinder acts by pushing forwardly or pulling backwardly in opposite directions. Automatic control of crawler belt correction from detection to correction in a dynamic manner is implemented, machine operating efficiency is improved, and safety risks are eliminated.

Description

Technical field [0001] The invention relates to a crawler machine that automatically corrects track and belt deviation, in particular to a solid material crawler type color sorter that automatically corrects track deviation. Background technique [0002] In the current existing technology, the working principle of the crawler solid material color sorter is as follows figure 1 As shown, the selected solid materials are transported to the crawler transport unit 12 through the vibrating feeding unit 14. The solid materials follow the crawler 1 and move forward horizontally in the running direction of the crawler. Due to the horizontal forward running speed provided by the crawler 1, when the solid When the material leaves the crawler 1, it will be thrown along the parabola 13, and the thrown material will enter the sorting unit. The sorting unit is equipped with a light source 4 and a photodetector 5. When the solid material enters the sorting unit along the moving track of the para...

AI Technical Summary

Problems solved by technology

[0005] 1. Manual observation cannot detect the deviation in time, and it is still inevitable that the left and right deviations exceed the range;

[0006] 2. Manual adjustment cannot achieve fineness and accuracy, and serious overshooting often occurs, which leads to more serious deviation in the other direction;

[0007] 3. Manual observation and adjustment must be accompanied by the whole production process, with a heavy workload and heavy tasks, which cannot meet the requirements of the automated production process;

[0008] 4. Manual observation and adjustment have great potential safety hazards, and it is difficult to meet the requirements of safe production
