Floating material fishing mechanical arm

Abstract

The invention discloses a floating material fishing mechanical arm. The floating material fishing mechanical arm comprises a hydraulic cylinder, a rotating motor, a support, a fishing umbrella and a spray head which is used for cleaning the fishing umbrella, the rotating motor is installed at the telescopic end of the hydraulic cylinder, the rotating end of the rotating motor is connected with the rear end of the support, the spray head and the fishing umbrella are both installed on the lower side of the front end of the support, the water spraying end of the spray head is located above the fishing umbrella, an umbrella control mechanism for controlling the fishing umbrella to be folded upwards or unfolded or folded reversely is arranged at the front end of the support, and the axis of the fishing umbrella is parallel to the axis of the hydraulic cylinder. The mechanical arm can complete all actions of fishing and throwing down floating materials, the umbrella fabric screen cloth can filter out all the floating materials larger than the aperture of the umbrella fabric screen cloth in the density liquid, some small-particle floating materials can be easily fished out, and therefore the experiment result can be more accurate.

Description

technical field [0001] The invention specifically relates to a salvage mechanical arm used for salvaging floating materials in a float-sink test. Background technique [0002] Floating and sinking tests are mainly used in jigging, heavy medium and other separation processes to guide production operations. According to the national standard, the larger the particle size is, the more coal is needed for the float-sink test, usually more than ten kilograms, which are floated and sunk in float-sink tanks of different density levels. This brings greater work intensity to the operators of the floating and sinking test. At the same time, most of the medicaments used in the floating and sinking test are harmful to the human body, and there are certain potential safety hazards. At present, the floating and sinking test is performed manually with a ladle. When the staff uses the ladle to scoop up the floating material, some small particles of the floating material are difficult to be...
