Abstract: Disclosed are a soft recoil system and a cannon having the same. The soft recoil system includes: a cannon barrel returning device mounted to a recoil device for absorbing a recoil force occurring when ammunition is fired, and configured to backward press a breech ring, such that the cannon barrel is fixed to a preset position; a cannon barrel fixing device installed at the recoil device, and configured to fix the cannon barrel when the cannon barrel returns to the fixed position; and a forward momentum generator connected to the recoil device and the breech ring, respectively, configured to forward move the cannon barrel by applying a force to the breech ring, such that the ammunition is fired while the cannon barrel forward moves, and configured to reduce a recoil force by partially attenuating recoil momentum resulting from the firing of the ammunition, by forward momentum.

Abstract: An apparatus for collecting empty cannon cartridges a bracket spacedly disposed from one or more surfaces of a breech ring for accommodating a cannon barrel therein; an operation pin mounted to the breech ring adjacent to the bracket; an upper link rotatably mounted to one surface of the bracket, and configured to slidingy contact the operation pin; a lower link concentric with the upper link, rotatably mounted to one surface of the bracket, and rotating together with the upper link by being engaged with the upper link at a specific angle; and a collecting unit having one end connected to the lower link, and configured to be unfolded such that empty cartridges extracted from the cannon barrel are collected. When the cannon barrel moves forward, the lower link rotates by being engaged with the upper link as the operation pin slides on the upper link, and the collecting unit is unfolded such that the empty cartridges are collected.

Abstract: An apparatus for opening and closing a breech block includes a cam follower, a housing, a first plunger, a rotation unit, a pressurizing unit, an open cam, a first elastic member, and a second plunger. In the present invention, in a state that the open cam is out of the range of a moving path of the cam follower so as to restrict rotation of the cam follower, the second plunger is inserted into the housing so as to support the pressurizing unit. This may allow a closed state of the breech block to be maintained after firing. Furthermore, in the present invention, a closed mode of the breech block may be converted into an open mode, through simple manipulations, e.g., by rotating the rotation unit, i.e., by moving the pressurizing unit.
