[0019] Optionally, the fixed door is fixedly connected with a sleeve, the sleeve is sleeved outside the rotating rod, and the rotating rod is rotationally connected with the sleeve.
[0020] By adopting the above scheme, the rotating rod is isolated from the explosive, and the rotation of the rotating rod is more smooth.
[0021] Optionally, the movable door comprises a plurality of same fan leaves, and the plurality of fan leaves are arranged in a circumferential array.
[0022] By adopting the above scheme, when the movable door is opened, the explosive in the explosive barrel flows out at the movable door more dispersedly, avoids the explosive from being stacked together to cause incomplete filling of the explosive pit, and also makes the explosive flow out more smoothly.
[0023] In summary, the present application has the following technical effects:
[0024] 1. By arranging the explosive pipe and the telescopic structure for extending the explosive pipe, the explosive pipe can be extended into the explosive hole and guide the explosive into the explosive hole, so that the addition of the explosive is more convenient.
[0025] 2. By arranging the chute to limit the rotation of the explosive pipe, the extension of the explosive pipe is more smooth.
