MOBILE AUTONOMOUS APPARATUS GENERATING AND SPRAYING INTO THE GROUND A MIXTURE OF TOXIC GASES TO DESTROY AND CHASE NOXIOUS BURROWING ANIMALS IN THEIR RUNS OR BURROWS

摘要

A mobile autonomous apparatus generating, propelling and spraying into the ground a mixture of toxic gases to destroy or chase noxious burrowing animals, such as moles, brown rats, coypus in their runs or burrows, is characterised by the use of a turbine (1) driven by an engine (2), sucking and propelling a gas flow constituted by a first supply of gas generated by a combustor (7) for diffusible substances, after ignition, located upstream of the turbine (1), then carried by a joining piece (3) into a mixing vessel (4) after recuperating in the case of an internal combustion engine, the exhaust gas (9) and the supplementary supply of gas stored in a cylinder (8). A plug (18) allows the addition of liquid and volatile toxic products into the mixing vessel (4) where mixing is effected. The contents of the burner (7), of the gas cylinder (8) and of the mixing vessel (4) can be used separately or jointly according to the treatment required. The gas flow coming from the mixing vessel (4) is carried in pipes (5) provided with a mobile cone (16) into the runs or burrous. The whole apparatus is attached by fasteners (13) on a frame (10) located in a structure (11) equipped with wheels (19), a pipe-holder (14) and a speed accelerator (12), the whole machine is self-propelled.
