Device for measuring adsorption force of particles at suction holes

The utility model relates to a device for measuring the adsorption force of particles at a suction hole, which belongs to the field of fluid mechanics and particle mechanics and comprises a replaceable suction tube body (1), a base (3), a transparent acrylic cover (4), a fan seat (6), a fan (7), particles (8), a particle supporting rod (9), a pressure sensor (11) and a measuring table (12). The change of the adsorption force on the particles along with the change of other factors is more obvious, and the study on the adsorption force on the seeds in a static state and the change of the adsorption force along with the factors by scholars of the air suction type seeding machine are facilitated. 本实用新型涉及一种颗粒在吸孔处所受吸附力的测量装置，属于流体力学与颗粒力学领域，包括可换吸管体（1）、基座（3）、透明亚克力罩（4）、风机座（6）、风机（7）、颗粒（8）、颗粒支撑杆（9）、压力传感器（11）、测量台（12），本实用新型通过杠杆原理将颗粒受到本身较小的力进行放大，让颗粒受到吸附力变化随其他因素变化更加明显，方便研究气吸式播种机的学者对种子处于静态时所受的吸附力及吸附力随因素变化进行探索或测定。
