[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] Unless otherwise specified, the technical means used in the embodiments are conventional means well known to those skilled in the art.

[0025] refer to Figure 1-Figure 4 The utility model discloses an application device of mixed explosives in smooth blasting, including a charging tube 1, wherein at least two strip holes 2 are arranged on the charging tube 1 along its length direction, and the strip holes 2 are evenly arranged on the charging tube 1. A medicine roll fixing mechanism is arranged in the charging tube 1, and the fixing mechanism is slidably arranged on the strip hole 2, and one end extends out of the charging tube 1 through the strip hole 2. The charging tube 1 is outerly provided with a locking ring 3 for locking the fixing mechanism, and at the same time, the medicine roll placed in the charging tube 1 is fixed. It should be noted that: a plurality of fixing mechanisms are arranged in each of the strip holes 2, and the number is the same, and the number of fixing mechanisms and the number of locking rings 3 on the same strip hole 2 are the same. As one embodiment: refer to Figure 3 As shown, there are three strip holes evenly distributed on the charge tube. The fixing structure is slidably arranged on the charge tube, and three fixing mechanisms in the same radial direction form a group to fix the medicine rolls loaded into the charge tube. The fixing mechanism can move along the strip holes, thereby achieving the purpose of adjusting the distance between the medicine rolls.

[0026] Furthermore, the fixing mechanism includes a fixing plate 4 located in the charge tube 1, the fixing plate 4 is fitted with the inner wall of the charge tube 1, a wedge block 5 is provided on one side of the fixing plate 4 close to the inner wall of the charge tube 1, the wedge block 5 extends out of the charge tube 1 through the strip hole 2, and the inclined surface of the wedge block 5 is arranged toward the locking ring 3. It should be noted that the shape of the fixing plate is adapted to the shape of the charge tube. When the charge tube is cylindrical, the fixing plate is arc-shaped; when the charge tube is a square tube, the fixing plate is a straight plate. Of course, the fixing plate can also be set into a rod shape according to actual needs, which can also achieve the purpose of the invention of the utility model. When no medicine roll is placed in the charge tube, the fixing plate fits with the inner wall of the charge tube, so that it can fix medicine rolls of different diameters and adapt to more sizes.

[0027] Furthermore, in order to prevent the fixing mechanism from falling into the charge tube and prevent the fixing plate from being able to remain in contact with the inner wall of the charge tube, support plates 6 are provided on both sides of the wedge block 5 near its top, and a guide rod 7 is provided through the support plate 6. A baffle 13 is fixed to one end of the guide rod 7 extending out of the support plate 6. A spring 8 is sleeved on the guide rod 7. A slider 9 in contact with the charge tube 1 is provided at the bottom of the wedge block 5. The other end of the spring 8 abuts against the slider 9. The slider 9 is slidably provided on the guide rod 7, so that the slider abuts against the outer wall of the charge tube under the action of the spring, so that the wedge block is located in the strip hole and the fixing plate is in contact with the inner wall of the charge tube. It should be noted that the support plate 6 is provided at a position close to the right-angled surface of the wedge block 5, that is, the support plate is provided at the highest position of the wedge block, so as to prevent the support plate from blocking the locking ring when the locking ring moves toward the wedge block, so that the medicine roll cannot be fixed. The slider is adapted to the shape of the outer wall of the charge tube, so that when the wedge block moves in the strip hole, the slider slides on the outer wall of the charge tube. When fixing the wedge block, move the locking block toward the wedge block so that the lowest part of the inclined surface of the wedge block is inserted into the through hole, so that the wedge block and the locking ring are fixed. When performing this operation, the wedge block can also be moved toward the locking ring, so that the two are fixed. At the same time, in the process of inserting the wedge block into the through hole, the wedge block as a whole moves toward the charge tube, so as to fix the medicine rolls that enter the area surrounded by the fixed plate. At the same time, in the process of the wedge block moving with the fixed plate toward the center of the charge tube, the area surrounded by the fixed plate gradually decreases, so that medicine rolls of different diameters can be fixed, and the scope of application is wider.

[0028] It should be further explained that: in the initial state, the spring, baffle, guide rod and slider can make the wedge block extend out of the charge tube to the maximum extent, that is, the spring, baffle, guide rod and slider support the wedge block and the fixing plate and other components, so that in the initial state, the fixing plate and the inner wall of the charge tube are in a state of being in contact. Therefore, the fixing mechanism will not slide freely on the strip hole.

[0029] Furthermore, the locking ring 3 is provided with a through hole 10 for the charge tube 1 to pass through, and the through hole 10 is trumpet-shaped, and the large diameter end is arranged toward the wedge block 5. It should be noted that the inclination angle of the inclined surface of the through hole is consistent with the inclined surface angle of the wedge block, so that when the wedge block is inserted into the through hole, it is a surface-to-surface contact, and the stability is better. The diameter of the through hole is adapted to the lowest part of the inclined surface of the wedge block, so that the lower end of the wedge block can be smoothly inserted into the through hole.

[0030] Furthermore, a limiting plate 11 is provided on the inner wall surface of the fixing plate 4, and the limiting plate 11 is provided perpendicular to the fixing plate 4 and is provided at an end away from the opening end of the charging tube 1. When the medicine roll is placed in the charging tube, it is limited by the limiting plate to prevent the medicine roll from not falling into the area surrounded by the fixing plate. It should be noted that in order to enable the medicine roll to be fixed at different positions of the charging tube, the diameter of the medicine roll must be smaller than the area surrounded by the limiting plate, so that the medicine roll can pass through the fixing mechanism near the pipe opening of the charging tube and enter the next set of fixing mechanisms.

[0031] For further reference, Figure 5 As shown, a plurality of grooves 12 are respectively arranged on both sides of the strip hole 2, and the grooves on both sides are arranged symmetrically. The arrangement of the grooves can mark the position of the wedge blocks to avoid inconsistent heights of the wedge blocks on the charge tube in the same radial direction.

[0032] When using the utility model, the medicine roll can be placed into the area surrounded by the fixing plate at the bottom of the medicine charging tube with the help of the existing clamp (or other methods), and then, the locking ring is operated to insert one end of the wedge block into the through hole, and the locking ring is continuously pressed on the wedge block, so that the wedge block moves toward the medicine charging tube with the fixing plate until the medicine roll is fixed; at the same time, the spring is compressed and exerts a force on the through hole, so that the wedge block is better fixed in the through hole, thereby achieving the fixation of the medicine roll.

[0033] Then adjust the position of the fixing mechanism close to the fixed medicine roll, adjust it to the specified position as needed, operate the locking ring to partially insert the wedge block into the through hole, retract the limit plate to be smaller than the diameter of the medicine roll, so that when the medicine roll is placed, it contacts the limit plate, and then continue to operate the locking ring to fix the medicine roll. This process can also be operated manually, that is, hold the wedge block on the medicine charging tube to retract the limit plate, place the medicine roll, operate the locking ring, and move the wedge block toward the inside of the medicine charging tube until the medicine roll is fixed. When placing and fixing the medicine roll in other positions, just operate in the above manner. When the utility model is in use, the operation method is not fixed. The above is just one of the operation methods. Workers can perform corresponding operations according to actual needs or work habits.

[0034] In the description of the present invention, it should be understood that the terms "longitudinal", "lateral", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside" and "outside" etc., indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present invention.

[0035] The embodiments described above are only descriptions of the preferred methods of the present invention, and are not intended to limit the scope of the present invention. Without departing from the design spirit of the present invention, various modifications and improvements made to the technical solutions of the present invention by ordinary technicians in this field should fall within the protection scope determined by the claims of the present invention.
