AI Technical Summary

Technical Problem

Existing sampling rods have a simple structure, making it difficult to quickly sample grains with high impurity content and clumps, and they are prone to clogging the sampling port, affecting sampling efficiency.

Method used

An automatic grain sampling device for ship holds was designed. It adopts a multi-stage telescopic crossarm and a grain detection mechanism, combined with a lower insertion sampling tube and a grain sampling unit. Through rotation, extension and closure, and with the help of air guides and opening and closing claws, it realizes automatic sampling and auxiliary drying of grain, avoiding clumping.

Benefits of technology

It improved the efficiency of food sampling in the ship's hold, ensured stability and speed, avoided blockages, and enhanced the automation of the sampling process.

Abstract

The present application relates to the technical field of automatic intelligent grain taking, in particular to a ship cabin grain automatic taking and sampling equipment and a use method thereof, which comprises a grain pile embeddable base, a rotary motor is fixedly installed inside the grain pile embeddable base, a rotary bearing seat is fixedly connected to the output shaft of the rotary motor, a multi-stage telescopic cross arm is fixedly connected to the outer surface of the rotary bearing seat, an operation box is fixedly installed at the output end of the multi-stage telescopic cross arm, a sampling rod is movably connected inside the operation box, and a grain detecting mechanism is arranged at the bottom end of the sampling rod. Through the combination of the sampling rod and the grain detecting mechanism, the grain detecting mechanism is optimized and designed, the rotary downward extension and closure of the lower insertion sampling cylinder, the grain taking unit and the bottom end of the upper sleeve rod are adopted, the grain detecting and sampling in the ship cabin are ensured, and through the combination of the hollow part and the inner hollow cylinder, the automatic sampling of the grain during the recovery of the lower insertion sampling cylinder and the grain taking unit is met.
