Description

Continuous grenade feeding device Technical Field The invention discloses a grenade continuous feeding device, which belongs to the technical field of unmanned aerial vehicles and is used for continuously feeding grenades when the grenades are put on a target area in an air-drop mode. Background At present, unmanned aerial vehicle platforms are very mature in use and complete systems are established, unmanned aerial vehicles can be utilized for carrying out the works of material throwing, regional investigation and the like, but from the point of view of current use, the material throwing mode by utilizing the unmanned aerial vehicles is single, and is mainly limited by the weight of a throwing device and the complexity factors of a mechanism. The inquired automatic grenade throwing device applied to the unmanned aerial vehicle has the main structure that a grenade is stored in a grenade throwing barrel in a barrel form, and the grenade in the throwing barrel is in an empty state after being thrown. The unmanned aerial vehicle has the advantages that the plurality of grenades are required to be carried, a plurality of bullet throwing barrels are required to be mounted, the dead load quality of the unmanned aerial vehicle is increased, and the overall bullet carrying quantity is reduced. Therefore, the grenade throwing device mounted on the existing unmanned aerial vehicle platform has the defect of being incapable of continuously supplying the grenades. Disclosure of Invention The invention aims to solve the problem of continuous grenade supply of a grenade throwing device, and provides a grenade continuous supply device suitable for unmanned aerial vehicle platform mounting. The grenade continuous bullet supply device comprises a shell 1, a flexible rope 2, an automatic rope collecting box 3, a sliding rail 4, a bullet ejecting block 5 and a pull ring fixing frame 6, wherein the sliding rail 4 and the automatic rope collecting box 3 are fixed on the shell 1, the flexible rope 2 extends out of the automatic rope collecting box 3, the free end of the flexible rope 2 is fixed on the bullet ejecting block 5, the shell 1 is provided with a bottom upper limit surface 101, a bottom lower limit surface 103, a bottom side limit surface 102, a top side limit surface 104 and a top upper limit surface 105, one end of the bullet ejecting block 5 is a guide mechanism 502 which can freely slide along a double sliding groove 402 of the sliding rail 4, the other end of the bullet ejecting block 5 is a curved surface structure 501 attached to a pull ring grenade shell 701, the pull ring fixing frame 6 is fixed with a pull ring type grenade pull ring 702, and the pull ring fixing frame 6 can freely slide along a lower opening sliding groove 401 of the sliding rail 4.
