Discharging funnel

A discharging hopper comprises a hopper, a discharging pipe is arranged at the bottom communicated with the hopper, an anti-blocking ball located above the discharging pipe is arranged in the hopper, and a driving motor used for driving the anti-blocking ball to rotate above the discharging pipe is connected with the anti-blocking ball. According to the blanking funnel, the anti-blocking ball is used for forming shielding support above the discharging pipe, rare earth permanent magnet neodymium iron boron alloy materials in the stock bin can be supported in the process that the storage tank topples over and the rare earth permanent magnet neodymium iron boron alloy materials enter a standard storage barrel, the materials are prevented from being completely accumulated and acting on the discharging pipe, the material guiding operation is smooth, and the working efficiency is improved. And the discharging efficiency of the vacuum rapid hardening furnace is ensured. 一种下料漏斗，包括料斗，连通料斗的底部设有出料管，所述料斗内设有位于出料管上方的防堵球，连接
