DEVICE FOR AUTOMATIC BATCHING AND FILLING PNEUMATIC TUBE CONTAINER WITH BULK PRODUCT SAMPLE Russian patent published in 2015 - IPC G01N1/20 B65B1/30 

FIELD: transport.

SUBSTANCE: invention relates to device for automatic batching, delivery of various bulk materials samples in containers by pneumatic tube for chemical and physical analysis at ore-dressing, primary metals, chemical and other plants. The device includes sample batching bin, charging pipe to container, sample container with holder and pneumatic actuator to control operations of opening, closing and transfer of the container. Also, inclined flat table with discharge opening is included in the device. On the table, reciprocative transportation mechanism is rigidly fixed the rod of which is connected with bottomless graduated cylinder and with protective wall which are pressed by spring to table surface. Herewith, table cant is selected from condition α_tab≥α_mat, where α_tab is table cant, α_mat is an angle of repose of sample material. Discharge opening diameter (d_p) is accepted from condition d_I>d_d>d_O, where d_I and d_O is inner and outer diameter of graduated cylinder.

EFFECT: reliability of sampling results.
