FIELD: agriculture. ^ SUBSTANCE: invention relates to devices to scare away wild animals, including birds, from the local areas, threatening their lives. The gun contains two pairs of barrels of caliber of smoke rockets. The barrels are rigidly mounted one above the other and equipped with unified for each horizontal pair of barrels percussion mechanisms. Behind the outer end face of each barrel a curved ramp is rigidly mounted. Each ramp is smoothly connected to the barrel channel and is directed as arc toward the axis of the barrel. Ramps of adjacent horizontal the barrels in the projection of the top form the shape of a dovetail. Angles of the sectors covered by the ramp arcs are the same in each horizontal pair of barrels but different in the vertical pairs. In the body of the gun between the inner ends of the barrels and rest of blank cartridges a slot is provided for the installation of autonomous cartridge with the charges. In the cartridge body from the side of the percussion capsular mechanisms the caliber and length of the channels correspond to the caliber and length of the blank cartridge sleeve, and the channels of from the side of the barrel - to the barrel caliber. Housings of smoke rockets are made spherical. The radius of ramp arcs is greater than the radius of the ball-shape of the body of the smoke rocket, and the length of the longest ramp arc is less than half the circumference of this form. ^ EFFECT: invention ensures effective animal scaring. |
