And as shown in Figure 5As shown, the structure process of the second back-shaped support frame 2 to support the upper feeding mechanism 3 is consistent with the structure process of the first back-shaped support frame 2 to support the upper feeding mechanism 3.

[0034] The embodiment also provides an application method of the automatic pearl rock raw material feeding system of emulsion explosive raw materials. Figures 1-5 , the specific steps are as follows:

[0035] S1, the crown block frame 1 drives the main frame 31 to gradually move above the material conveying belt 4, and the rigid peg harrow frame 33 enters the back-shaped hook 22 position in the first back-shaped support frame 2, and the back-shaped hook 22 is used to support the rigid peg harrow frame 33, at this time, the contraction spring 34 in the rigid peg harrow frame 33 is stretched, and the steel peg 332 is away from the equidistant circular hole 321 on the edge of the curved plate 32;

[0036] S2, when the curved plate 32 gradually moves out of the first back-shaped support frame 2 and is guided by the guide part 231, at this time, the rigid peg harrow frame 33 is gradually folded under the tension of the contraction spring 34, when the rigid peg harrow frame 33 completely leaves the first back-shaped support frame 2, the curved plate 32 completely covers the upper surface of the pearl rock raw material bag 5, the rigid peg harrow frame 33 is completely folded under the tension of the contraction spring 34, and the steel peg 332 penetrates through the equidistant circular hole 321 on the edge of the curved plate 32 and then penetrates into the pearl rock raw material bag 5, at this time, the main frame 31 is driven by the crown block frame 1 to transfer the pearl rock raw material bag 5 to above the vertical storage tank 6;

[0037] S3, after the main frame 31 is driven by the crown block frame 1 to transfer the pearl rock raw material bag 5 to above the vertical storage tank 6, the bottom of the pearl rock raw material bag 5 contacts the breaking cutter 73 at the central part of the frame body 71, and in the moving process of the main frame 31 driven by the crown block frame 1, the breaking cutter 73 cuts the pearl rock raw material bag 5, and the pearl rock raw material in the pearl rock raw material bag 5 is unloaded into the vertical storage tank 6 through the feeding port;

During the breaking process, the crown block 1 buffers the strong pulling and extruding force by the self-provided spring, so as to realize the buffer type balanced force breaking. When the pearl rock packaging bag 5 is broken and passes through the breaking cutter 73, the resistance borne by the feeding mechanism 3 is suddenly released, so as to force the compressed spring potential energy fixed on the crown block 1 and connected with the main frame 31 to be rapidly released, drive the feeding mechanism 3 to move violently, and then complete the cleaning of the pearl rock residual material attached to the packaging material, and completely clean the residual pearl rock raw material in the bag.

[0040] Of course, the above is only a typical example of the present application, and in addition thereto, the present application can have other various specific embodiments, and any technical solution formed by equivalent replacement or equivalent transformation falls within the scope of the present application.
