Stepless convenient and fast jigging machine polarization mechanism amplitude and frequency adjusting mechanism

Abstract

The invention discloses a stepless convenient and fast jigging machine polarization mechanism amplitude and frequency mechanism. An amplitude adjusting mechanism installed at the upper end of a powershaft is included, and comprises a rocking arm; the rocking arm is built-in and hollow; an amplitude adjusting part is installed in the rocking arm; and the end, away from the rocking arm, of the power shaft is connected with an outer five-pointed star hydraulic motor. The amplitude adjusting part is installed in the rocking arm, so that amplitude adjusting of a jigging structure is achieved; meanwhile, the end, away from the rocking arm, of the power shaft is connected with the outer five-pointed star hydraulic motor, so that the outer five-pointed star hydraulic motor provides torque power to drive the power shaft, and a throttling valve is used in cooperation to achieve a torque input rotating speed, and therefore frequency adjusting of the jigging structure is achieved, so that the device achieves that the amplitude is fast adjusted under a halt production state.

Description

technical field [0001] The invention belongs to the technical field of marine mining, and in particular relates to an amplitude and frequency adjustment mechanism of a polarization mechanism of a non-polar portable jig. Background technique [0002] The marine tin mining engineering ship is a marine resources engineering equipment operation platform integrating seabed excavation, cutter suction, primary screening, roughing, beneficiation, tailings treatment and other equipment. Among them, the roughing / fine selection equipment is the equipment that directly affects the production efficiency. The polarization mechanism is the most critical mechanism component with the largest number, frequent operation, and impact on accuracy in the roughing / selecting equipment. At present, the most commonly used polarization mechanisms in China are divided into two types: fixed amplitude and graded amplitude. Existing problems: fixed amplitude can provide constant jigging amplitude, result...

AI Technical Summary

Problems solved by technology

Existing problems: fixed amplitude can provide constant jigging amplitude, resulting in extended roughing / concentrating operation cycle, increased fuel consumption, and poor beneficiation accuracy. At present, it can only be applied to operating platforms with a daily output of less than 0.5 tons

Although it can meet a certain amount of daily output (1.5T), its graded mechanical structure cannot fully set the jigging amplitude when the accuracy is optimal, and there is a certain amount of tailings re-selection workload.

Due to its structural problems, the amplitude of the grade amplitude needs to be shut down every time the adjustment of the beneficiation amplitude is performed. Most of the adjustment processes are experimental settings, which cannot be verified online. The hysteresis is serious and the beneficiation workers have a lot of work.

The decrease in cumulative attendance rate leads to a decrease in production capacity (for example, the PAGAGON has shrunk by 32%)

The amplitude power of grades is driven by a single linear drive. When there are grade differentiation requirements for roughing / selecting, different grades require different power equipment to drive, resulting in increased fuel consumption, repeated tooling, and increased failure rates.
