High-precision automatic feeding instrument

Abstract

The invention discloses a high-precision automatic feeding instrument. The high-precision automatic feeding instrument comprises a storage system, a feeding system and a weighing platform, wherein the storage system comprises a tray, a rotating motor capable of driving the tray to rotate, crucibles distributed around the rotating center and a lifting motor capable of driving the tray to ascend and descend, wherein the crucibles are inserted into the tray in a suspended mode, the bottoms of the crucibles are higher than the weighing table, and after the crucibles are placed on the weighing table along with the tray, and the tray continues to descend and can be separated from the crucibles; and the feeding system comprises a feeding head with a cavity, a feeding shaft extending into the cavity and a lifting and rotating device for driving the feeding shaft to periodically lift and rotate, the bottom end of the feeding head is provided with a discharging port right facing the weighing table, the side wall of the feeding head is provided with a feeding port, a quantitative groove is formed nearby a position located above the bottom end of the side face of the feeding shaft, a stirring protrusion is arranged above the quantitative groove, the quantitative groove blocks the discharging port when the feeding shaft is in an upper position, and the quantitative groove extends out of the discharging port when the feeding shaft is in a lower position. According to the invention, full-automatic feeding, feeding weighing and carrying away and storing are achieved, feeding efficiency is high, and high-precision feeding is guaranteed.

Description

technical field [0001] The invention belongs to the field of mineral sample experimental equipment, and in particular relates to a high-precision automatic feeding instrument. Background technique [0002] When conducting experiments on mineral samples, multiple samples need to be used at high frequency, but the current sample feeding is either high in efficiency but low in precision, or high in precision but low in efficiency, which cannot meet the needs of the experiment. Contents of the invention [0003] The purpose of the present invention is to provide a high-precision automatic feeding instrument, which can realize fully automatic feeding, feeding weighing and transporting away the stored materials, with high feeding efficiency and high-precision feeding. [0004] The technical scheme adopted in the present invention is: [0005] A high-precision automatic feeding instrument, including a material storage system, a feeding system and a weighing platform; the materia...
