Low-energy bullet

Abstract

The invention discloses a low-energy bullet which comprises a grinding box body. A first grinding device, a second grinding device, a powder collecting deice and a blocking door component are arrangedin the grinding box body. The first grinding device comprises a first transmission cavity. A second transmission cavity is arranged on the left side of the first transmission cavity. A hydraulic cylinder is fixedly mounted in the inner wall of the left side of the second transmission cavity. An L-shaped press plate is fixedly mounted on the end face of the right side of a piston push rod of the right side of the hydraulic cylinder. A rack is arranged below the end face of the rear side of the L-shaped press plate. A first rotating shaft is mounted in the bottom wall of the second transmissioncavity in a running fit manner. A first gear is fixedly mounted on the first rotating shaft and is engaged with the rack on the rear side of the L-shaped press plate. A second rotating shaft is mounted at the position, located on the right side of the first rotating shaft, in the bottom wall of the second transmission cavity in a running fit manner. A second gear is fixedly mounted on the secondrotating shaft.

Description

technical field [0001] The invention relates to the military field, in particular to a low-energy bullet. Background technique [0002] During military training, in order to reduce dangerous situations such as accidental injury, low-energy bullets are used for training. In order to reduce the power of bullets, the gunpowder used is also a key part. Smokeless gunpowder is too powerful, so black powder is used to make the required gunpowder. Gunpowder, coal powder is used in the gunpowder, the coal particles ground by general grinding devices are not fine enough, and the device is large and complicated, and the coal dust will also float out and be harmful to the human body. Therefore, a kind of simple structure, good grinding effect and internal closed Grinding device. Contents of the invention [0003] The object of the present invention is to provide a low-energy bullet for overcoming the above-mentioned defects in the prior art. [0004] A low-energy bullet according to...
