Abstract

Technical Field
[0001] This utility model relates to the field of explosives loading technology, and more specifically, to a powdered explosives loading device for underground mines. Background Technology
[0002] Powdered explosives are solid explosives made from a mixture of ammonium nitrate, wood flour, TNT, and other components. They are characterized by easy diffusion, high detonation velocity, and stable storage. They are widely used in mining blasting, engineering demolition, and military applications. Their fine particles make them easy to fill and transport. They must be detonated by a detonator or detonating cord. Their power can be adjusted by mixing proportions, but strict management is required to prevent accidental detonation or illegal use. Safety regulations must be followed to ensure the safety of personnel and the environment.
[0003] When using powdered explosives, operators often use corresponding loading equipment to fill the explosives. Existing loading equipment usually has an internal stirring structure to prevent the powdered explosives from clumping, which could lead to blockage of the feed pipe and difficulty in feeding. However, the stirring position of the stirring blades and the loading cylinder are relatively fixed, which makes it difficult to stir the areas between the stirring blades, creating stirring dead zones. This affects the effect of breaking up powder clumps, so it needs to be improved. Utility Model Content
[0004] In order to overcome the shortcomings of the existing technology, this utility model provides a powdered explosive loading device for underground mines, which has the advantage of good dispersion effect.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a powdered explosive loading device for underground mines, comprising a base plate, a fixed frame fixedly connected to the top of the base plate, a loading cylinder fixedly sleeved inside the fixed frame, a connecting frame fixedly connected to the top of the loading cylinder, a sliding plate movably connected to the inner surface of the connecting frame, a servo motor fixedly connected to the left side of the connecting frame, a first rotating shaft fixedly sleeved at the other end of the output shaft of the servo motor, the other end of the first rotating shaft passing through the connecting frame and extending to the right side of the connecting frame and fixedly sleeved with an eccentric rod, a hollow rod movably connected to the outer surface of the eccentric rod, a vertical rod fixedly connected to the top of the hollow rod, and the top of the vertical rod fixedly connected to the bottom of the sliding plate.
[0006] As a preferred embodiment of this utility model, a drive motor is fixedly connected to the top of the sliding plate, and a second rotating shaft is fixedly sleeved at the other end of the output shaft of the drive motor. The bottom end of the second rotating shaft passes through the medicine filling cylinder and extends into the inner cavity of the medicine filling cylinder, and a stirring rod is fixedly sleeved thereon. A second protective shell is fixedly connected to the outer surface of the drive motor, and the second protective shell is fixedly installed on the top of the sliding plate.
[0007] As a preferred embodiment of this utility model, a discharge box is fixedly connected to the bottom of the charging cylinder, a fixing pipe is fixedly connected to the bottom end of the discharge box, and a positioning sleeve located directly below the fixing pipe is fixedly installed on the top of the base plate.
[0008] As a preferred technical solution of this utility model, rectangular plates are fixedly connected to both the left and right sides of the front of the discharge box. A power motor is fixedly connected to the left side of the rectangular plate. A threaded rod is fixedly sleeved at the other end of the output shaft of the power motor. The other end of the threaded rod passes through the rectangular plate and extends into the interior of the rectangular plate, and a sliding block is threadedly sleeved thereon.
[0009] As a preferred embodiment of this utility model, a sleeve rod is fixedly connected to the top of the sliding block, and a rotating rod is movably connected inside the sleeve rod.
[0010] As a preferred embodiment of this utility model, a connecting rod is fixedly sleeved inside the top of the rotating rod, and the other end of the connecting rod passes through the discharge box and extends into the inner cavity of the discharge box and is fixedly sleeved with a feeding hopper. The outer surface of the feeding hopper is movably connected to the inner surface of the discharge box.
[0011] As a preferred embodiment of this utility model, a first protective shell is fixedly connected to the outer surface of the power motor, and the right side of the first protective shell is fixedly connected to the left side of the rectangular plate.
[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0013] 1. This utility model is equipped with a servo motor, a first rotating shaft, an eccentric rod, a vertical rod, and a hollow rod. When the servo motor is started, the first rotating shaft will drive the eccentric rod to rotate. At this time, the eccentric rod squeezes and pushes the vertical rod, causing the vertical rod to drive the sliding plate to move vertically upward under the limiting action of the connecting frame. This allows the second rotating shaft and the stirring rod to vibrate vertically up and down while rotating and dispersing, reducing the dead corners of dispersing and improving the stirring and dispersing effect of the stirring rod.
[0014] 2. This utility model, by setting up a sliding block, a sleeve rod, a rotating rod, a connecting rod, and a feeding hopper, starts the power motor, causing the threaded rod to rotate. At this time, the sliding block will drive the sleeve rod to move horizontally to the right along the outer surface of the discharge box, thereby causing the sleeve rod to squeeze and push the rotating rod, causing the rotating rod to drive the connecting rod and the feeding hopper to rotate. The feeding hopper is a quantitative cavity. After rotating 90 degrees, the cavity opening faces downward. The pre-set volume of powdered explosives in the cavity falls into the explosive packaging bag through the fixed tube. Thus, the fixed size and shape inside the feeding hopper realizes the function of quantitative loading of explosives, avoiding the situation of inconsistent loading amount.

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0022] like Figures 1 to 5 As shown, this utility model provides a powdered explosive loading device for underground mines, including a base plate 1, a fixed frame 2 fixedly connected to the top of the base plate 1, a loading cylinder 3 fixedly sleeved inside the fixed frame 2, a connecting frame 4 fixedly connected to the top of the loading cylinder 3, a sliding plate 5 movably connected to the inner surface of the connecting frame 4, a servo motor 6 fixedly connected to the left side of the connecting frame 4, a first rotating shaft 7 fixedly sleeved at the other end of the output shaft of the servo motor 6, the other end of the first rotating shaft 7 passing through the connecting frame 4 and extending to the right side of the connecting frame 4 and fixedly sleeved with an eccentric rod 8, a hollow rod 13 movably connected to the outer surface of the eccentric rod 8, a vertical rod 9 fixedly connected to the top of the hollow rod 13, and the top of the vertical rod 9 fixedly connected to the bottom of the sliding plate 5.
[0023] When the servo motor 6 starts running, it will cause the first rotating shaft 7 to drive the eccentric rod 8 to rotate. At this time, the eccentric rod 8 squeezes and pushes the vertical rod 9, causing the vertical rod 9 to drive the sliding plate 5 to move vertically upward under the limiting action of the connecting frame 4.
[0024] The top of the sliding plate 5 is fixedly connected to a drive motor 10, and the other end of the output shaft of the drive motor 10 is fixedly sleeved with a second rotating shaft 11. The bottom end of the second rotating shaft 11 passes through the medicine filling cylinder 3 and extends into the inner cavity of the medicine filling cylinder 3 and is fixedly sleeved with a stirring rod 12. The outer surface of the drive motor 10 is fixedly connected to a second protective shell 26, and the second protective shell 26 is fixedly installed on the top of the sliding plate 5.
[0025] When the drive motor 10 starts running, it will cause the second rotating shaft 11 to drive the stirring rod 12 to rotate.
[0026] The bottom of the charging cylinder 3 is fixedly connected to the discharge box 14, the bottom end of the discharge box 14 is fixedly connected to the fixing pipe 15, and the top of the base plate 1 is fixedly installed with the positioning sleeve 16 located directly below the fixing pipe 15.
[0027] The dispersed explosive powder will pass through the discharge box 14 and the fixing pipe 15 in sequence and be poured into the explosive packaging bag placed in the positioning sleeve 16.
[0028] The discharge box 14 has rectangular plates 17 fixedly connected to both the left and right sides of the front. A power motor 18 is fixedly connected to the left side of the rectangular plate 17. A threaded rod 19 is fixedly sleeved at the other end of the output shaft of the power motor 18. The other end of the threaded rod 19 passes through the rectangular plate 17 and extends into the interior of the rectangular plate 17, and a sliding block 20 is threadedly sleeved thereon.
[0029] When the power motor 18 starts running, it will cause the threaded rod 19 to rotate. At this time, the sliding block 20 will move horizontally to the right along the outer surface of the discharge box 14.
[0030] The top of the sliding block 20 is fixedly connected to a sleeve rod 21, and the inside of the sleeve rod 21 is movably connected to a rotating rod 22.
[0031] When the sliding block 20 drives the sleeve rod 21 to move to the right in sync, the sleeve rod 21 will squeeze and push the rotating rod 22, causing the rotating rod 22 to swing.

The other end of the connecting rod 23 passes through the discharge box 14 and extends into the inner cavity of the discharge box 14, and is fixedly sleeved with a feeding hopper 24. The outer surface of the feeding hopper 24 is movably connected to the inner surface of the discharge box 14.
[0033] When the connecting rod 23 rotates, it will drive the hopper 24 to rotate synchronously in the inner cavity of the discharge box 14.
[0034] Among them, a first protective shell 25 is fixedly connected to the outer surface of the power motor 18, and the right side of the first protective shell 25 is fixedly connected to the left side of the rectangular plate 17.
[0035] Due to the design of the No. 1 protective shell 25, the power motor 18 is sealed off, preventing dust from entering the power motor 18 during the loading process.
[0036] Working principle and usage process of this utility model:
[0037] First, place the explosive packaging bag to be filled into the positioning sleeve 16, and add powdered explosive into the charging cylinder 3. At this time, start the drive motor 10, so that the second rotating shaft 11 drives the stirring rod 12 to rotate synchronously. At the same time, start the servo motor 6, so that the first rotating shaft 7 drives the eccentric rod 8 to rotate. At this time, the eccentric rod 8 squeezes and pushes the vertical rod 9, so that the vertical rod 9 drives the sliding plate 5 to move vertically upward under the limiting action of the connecting frame 4. Thus, the second rotating shaft 11 and the stirring rod 12 vibrate vertically up and down while rotating and dispersing, reducing the dead corners of dispersing and improving the stirring and dispersing effect of the stirring rod 12.
[0038] After stirring and dispersing, the power motor 18 is started, causing the threaded rod 19 to rotate. At this time, the sliding block 20 will drive the sleeve rod 21 to move horizontally to the right along the outer surface of the discharge box 14, so that the sleeve rod 21 squeezes and pushes the rotating rod 22, causing the rotating rod 22 to drive the connecting rod 23 and the feeding hopper 24 to rotate. The feeding hopper 24 is a quantitative cavity. After rotating 90 degrees, the cavity opening faces downward. The pre-filled volume of powdered explosive in the cavity falls into the explosive packaging bag through the fixed tube 15. Thus, the fixed size and shape inside the feeding hopper 24 realizes the function of quantitative loading, avoiding the situation of inconsistent loading.
