Furthermore, two sliding grooves are horizontally formed in the side wall of the cylinder, the two sliding grooves are arranged oppositely, one sliding groove penetrates through the side wall of the cylinder and is a waist-shaped through hole, two ends of the rotating strip are in lap joint with the sliding grooves, and one end of the rotating strip extends out of the side wall of the cylinder through the sliding groove and is connected with the handle; the rotating strip is convenient to operate and rotate, the size of the gap of the filter screen is changed, and the rotating strip is suitable for containing blocky explosives with different sizes.

Furthermore, the explosive-filling device also comprises an annular baffle which is fixedly connected to the edge of the top end of the funnel, so that the explosive is prevented from being spilled out during explosive filling.

Further, the funnel is connected with the cylinder through threads, so that the funnel can be conveniently detached, cleaned and transported.

Compared with the prior art, the beneficial effects of the utility model are that:

(1) the device is based on a structure that the loading area of the funnel is increased, and the filter screen is arranged below the funnel, so that large block-shaped explosives can be screened out, the block-shaped explosives are conveniently and timely smashed, the blast hole is prevented from being blocked by the block-shaped explosives, and the problem that later-period through holes are difficult is solved;

(2) the filter screen is provided with 2-3 filter strips, each filter strip comprises a rotating strip and a fixing strip, and the rotating strips and the fixing strips are arranged in a staggered mode, so that the structure is simplified, the arrangement is easy, massive explosives which easily cause blast hole blockage can be screened out, and the explosive is not excessively meticulous and is prevented from falling to influence the explosive charging efficiency;

(3) the side wall of the cylinder is provided with a sliding groove, two ends of the rotating strip are lapped on the sliding groove, and one end of the rotating strip extends out of the side wall of the cylinder to be connected with the handle, so that the rotating strip can be conveniently rotated around the circle center along the sliding groove through the handle, the size of a gap between the rotating strip and the fixing strip is changed, and the rotating strip is suitable for filtering block explosives with different sizes;

(4) the upper end of the funnel is provided with the annular baffle, so that the collection of the explosive is facilitated, and the explosive is prevented from being spilled;

(5) the funnel and the cylinder are connected through threads, so that the funnel and the cylinder are convenient to clean after being disassembled, and the blockage caused by the fact that the explosive adheres to the filter screen after being used for a long time is avoided.
