Automatic test tube cleaning device for analytical chemistry laboratory

The invention provides an automatic test tube cleaning device for an analytical chemistry laboratory, and mainly relates to the field of analytical chemistry. The automatic test tube cleaning device for the analytical chemistry laboratory comprises a bottom plate and a control box. Vertical plates are arranged on the two sides of the top face of the bottom plate. An installing plate is arranged atthe upper ends of the two vertical plates. A groove is formed in the bottom face of the installing plate. A plurality of first chain wheels are arranged on the inner wall of the top face of the groove and are in meshing connection through a first chain. The automatic test tube cleaning device has the beneficial effects that through the arrangement of first brushes and second brushes, the interiors and the exteriors of the test tubes can be cleaned at the same time, test tube cleaning is more thorough, and the test tube cleaning effect is improved; and through cooperation of the chain wheels and the chain and single p
