[0002] Artillery refers to a barreled firing weapon that uses mechanical energy, chemical energy (gunpowder), electromagnetic energy and other energy to project projectiles. Its range exceeds the range of individual weapons. It consists of two major parts: a gun body and a gun carriage. It has a caliber of not less than 20 mm. Artillery includes self-propelled artillery, towed artillery, vehicle-mounted artillery, etc. Among them, when towed artillery is in use, it is necessary to lower the spade on the gun carriage to support the ground to offset part of the recoil of the artillery. When the spade supports the ground, it is necessary to dig a spade pit of corresponding size. Before digging a pit with the spade of the existing gun carriage, the spade is usually controlled to contact the ground first, and then the spade pit range is marked along the edge of the spade, and finally the spade pit is dug. The above steps need to be repeated each time the artillery is used, which is not conducive to improving the efficiency of the artillery. Utility Model Content
