Quantitative proportioning machine facilitating feeding

The utility model belongs to the technical field of water-soluble fertilizer production, particularly relates to a quantitative proportioning machine convenient for feeding, and provides the following scheme aiming at the two problems that the quantitative proportioning machine convenient for feeding provided by the background technology does not have a quantitative proportioning function and does not have a water-soluble fertilizer protection function: the quantitative proportioning machine convenient for feeding comprises a proportioning mechanism and a protection mechanism, the proportioning mechanism comprises a mounting table, a supporting table is arranged at the top of the mounting table, supporting legs are welded to the four corners of the bottom of the supporting table, and a feeding opening is formed in the top of the supporting table; and the protection mechanism comprises a protection box. According to the water-soluble fertilizer weighing device, a worker puts a water-soluble fertilizer into the
