The invention discloses a medicine adding cover of a liquid medicine box, the liquid medicine box and plant protection equipment, and the medicine adding cover comprises a mounting ring which is used for being mounted on a mounting opening of the liquid medicine box, and a medicine adding through hole is formed in the mounting ring; the at least two first liquid blocking pieces are arranged around the periphery of the dosing through hole, and the first liquid blocking pieces are elastically connected with the mounting ring; in a dosing state, a dosing pipe can be inserted into the mounting ring, and each first liquid baffle plate is extruded by the inserted dosing pipe, so that the dosing pipe can penetrate through the dosing through hole; and in a natural state, each first liquid blocking sheet is recovered to a position for sealing the dosing through hole under the action of resilience force. According to the scheme, the medicine adding pipe can be directly inserted into the medicine adding through hole of the medicine adding cover to add medicine liquid under the condition that the medicine adding cover is not opened; after medicine adding is completed, along with pulling-out of the medicine adding pipe, the first liquid blocking piece can automatically restore to the original shape under the action of resilience force, sealing of the medicine adding through hole is achieved, and manual cover closing operation is not needed.

    本发明公开一种药液箱的加药盖、药液箱以及植保设备,包括:安装圈,用于安装于药液箱的安装口上,所述安装圈中设置加药通孔;至少两个第一挡液片,围绕所述加药通孔的周缘设置,且所述第一挡液片与所述安装圈弹性连接;在加药状态下,加药管可插入所述安装圈中,各所述第一挡液片被插入的加药管挤开,使得所述加药管能够穿过所述加药通孔;自然状态下,各所述第一挡液片在回弹力作用下恢复至封闭所述加药通孔的位置。本方案可以在不打开加药盖的情况下,直接将加药管插入加药盖的加药通孔中添加药液;在完成加药后,随着加药管的拔出,第一挡液片在回弹力的作用下会自动恢复原状,实现对加药通孔的封闭,无需再人工合盖的操作。
