[0029] Specifically, when it is necessary to build a loading and unloading channel, the hydraulic rod 13 is started to make the hydraulic rod 13 extend and retract, and with the extension and retraction of the hydraulic rod 13, the collar 14 rotates around the fixed shaft 15, and simultaneously drives the tail plate base body 1 to move, so that the tail plate base body 1 rotates around the connecting rod 17 as the rotation shaft. Under the continuous action of the hydraulic rod 13, the tail plate base body 1 gradually adjusts to a suitable angle, and builds an inclined loading and unloading channel from the ground to the carriage 20. The carriage 20 serves as a core space for carrying blasting materials, and the inside of the carriage 20 is specially designed to have multiple protection functions such as fireproofing, anti-static, shock absorption, etc., to ensure the absolute safety of the blasting materials during transportation.

[0030] Working principle: when the motor 3 is started to operate, the lower transmission roller 2 is driven to rotate. Since the two transmission rollers 2 are connected through the conveying belt 4, the conveying belt 4 also moves under the action of the rotation of the transmission roller 2, so as to realize the conveying of the blasting materials placed on the conveying belt 4 along the belt, facilitating the loading and unloading operation. The tail plate base body 1 is internally provided with two accommodating grooves 5, and the electric push rod 6 in the accommodating groove 5 can extend and retract.

[0031] In addition to the static plate 21 in the fixed state, the spring 1109 is in the stretched state. When it is necessary to replace the static plate 21, the pressure rod 1106 is rotated to make the position of the pressure rod 1106 coincide with the position of the through hole 1105. Under the resetting action of the spring 1109, the pressure rod 1106 moves downward through the inner wall of the through hole 1105, so that the pressure rod 1106 completely separates from the pressing plate 1104. At this time, the pressing plate 1104 can rotate freely. By rotating the pressing plate 1104 to a certain angle, the fixing effect on the static plate 21 is lost, and then the static plate 21 is disassembled. Then, a new static plate 21 is taken out, and the static plate 21 is placed on the left side of the pressing plate 1104. Then, the pressing plate 1104 is rotated and tightly attached to the surface of the static plate 21. Then, the pressure rod 1106 is stretched and passes through the through hole 1105, so that the top of the pressure rod 1106 completely passes through the through hole 1105. At this time, the spring 1109 is stretched, and the pressure rod 1106 is rotated. Then, the pressure rod 1106 is loosened. At this time, the spring 1109 will reset to clamp the pressure rod 1106 on the surface of the pressing plate 1104, thereby realizing the fixing effect of the new static plate 21.
