[0050] Embodiment 1

[0051] As attached Figure 1 -Attached Figure 8 As shown, the present invention is an automatic charging device for blasting, comprising a charge pushing mechanism 2 and a charge barrel 1 having a charge delivery opening 11 at one end, the charge delivery opening 11 is used to deliver the explosive 4 in the charge barrel 1 to the charge hole at the destination to be charged, and can also be used to load the explosive 4 into the charge barrel 1;

[0052] The medicine pushing mechanism 2 includes a medicine feeding bottom plate 21, a medicine feeding push plate 22 and a medicine pushing driving mechanism 23. The medicine feeding push plate 22 is arranged at one end of the medicine charging barrel 1 away from the medicine feeding opening 11. When charging, the medicine feeding push plate 22 is used to push the end of the explosive 4 to move along the axial direction of the medicine charging barrel 1 to the medicine feeding opening 11 side, so as to push the explosive 4 to move into the charging hole. The medicine feeding bottom plate 21 is arranged at the bottom of the medicine charging barrel 1, and is used to carry the explosive 4 when charging.

[0053] The medicine pushing drive mechanism 23 includes a linear drive mechanism 231, a push plate drive rod 232, a bottom plate drive mechanism 233 and a bracket 234, and the bracket 234 is fixedly connected to the medicine cartridge 1;

[0054] The base plate driving mechanism 233 includes an elastic telescopic rod 2331, a fixed baffle 2332 and a movable baffle 2333, the end of the first rod body 23311 of the elastic telescopic rod 2331 is fixedly connected to the medicine delivery base plate 21, and the end of the second rod body 23312 is connected to the output end of the linear driving mechanism 231, that is, the two ends of the elastic telescopic rod 2331 are respectively connected to the medicine delivery base plate 21 and the output end of the linear driving mechanism 231, wherein the first rod body 23311 can be a pipe sleeve structure, and the second rod body 23312 can be a rod body structure slidably arranged in the pipe sleeve, conversely, the second rod body 23312 can be a pipe sleeve structure, and the first rod body 23311 can be a rod body structure slidably arranged in the pipe sleeve, preferably, a spring 23313 is arranged in the pipe sleeve, one end of the spring 23313 abuts against the bottom of the pipe sleeve, and the rod body The end portion abuts against the other end of the spring 23313, thereby realizing the elastic expansion and contraction of the elastic telescopic rod 2331, the movable baffle 2333 is arranged at the other end of the first rod body 23311, that is, the movable baffle 2333 is arranged at one end of the first rod body 23311 close to the second rod body 23312, the fixed baffle 2332 is arranged on the bracket 234 and is located on the moving path of the movable baffle 2333, when the linear drive mechanism 231 drives the elastic telescopic rod 2331 to move, the elastic telescopic rod 2331 moves as a whole until the movable baffle 2333 abuts against the fixed baffle 2332, at this time, the first rod body 23311 cannot continue to move, and the second rod body 23312 compresses the spring 23313 to slide relative to the first rod body 23311, and at this time, the elastic telescopic rod 2331 contracts;

[0055] One end of the push plate driving rod 232 is connected to the medicine delivery push plate 22, and the other end is connected to the output end of the linear driving mechanism 231, that is, when the linear driving mechanism 231 is working, it will synchronously drive the push plate driving rod 232 and the elastic telescopic rod 2331 to move. After synchronously moving a certain distance, the first rod body 23311 of the elastic telescopic rod 2331 stops moving, and the push plate driving rod 232 and the second rod body 23312 continue to move synchronously. The reaction on the medicine delivery bottom plate 21 and the medicine delivery push plate 22 is that when the linear driving mechanism 231 is working, the medicine delivery bottom plate 21 and the medicine delivery push plate 22 move synchronously to transport the explosive 4 to the charging hole at the destination to be loaded. After synchronously moving a certain distance, the medicine delivery bottom plate 21 stops moving, while the medicine delivery push plate 22 continues to move, so that the explosive 4 is separated from the medicine delivery bottom plate 21 and reaches the destination.

[0056] The automatic charging device for blasting provided by the present invention can improve the success rate of charging by avoiding friction between the explosive 4 and the charging hole through the design of the charging pushing mechanism 2, that is, on the one hand, it can avoid friction or extrusion between the explosive 4 and the bottom wall of the charging hole during the charging process, causing the explosive 4 to be damaged and become a dud, or avoid the problem that the explosive 4 cannot be delivered to the appropriate depth of the charging hole due to excessive friction. On the other hand, before reaching the destination, the charging bottom plate 21 can stop moving, which can ensure that the explosive 4 is separated from the automatic charging device for blasting, and avoid the explosive 4 being reset together when the charging bottom plate 21 and the charging pushing plate 22 are reset, thereby improving the success rate of charging.

[0057] In addition, the device only needs one linear drive mechanism 231 to realize the function of first synchronously moving the medicine delivery base plate 21 and the medicine delivery push plate 22, and then stopping the medicine delivery base plate 21 while the medicine delivery push plate 22 continues to move, so that the overall structure is simple and the cost is low.

[0058] Reference Figure 1 , Attachment Figure 2 and attached Figure 4 In one embodiment, the upper end of the charge cartridge 1 is provided with a charge hole 12, and the charge cartridge 1 is connected with a charge storage cartridge 3 at the charge hole 12, and the charge storage cartridge 3 is used to replenish the explosive 4 to the charge cartridge 1 through the charge hole 12. That is, a plurality of explosives 4 can be stacked on the charge storage cartridge 3, thereby greatly reducing the number of times of loading the explosives 4, thereby effectively improving the continuity of charge loading and improving the blasting efficiency.

[0059] In one embodiment, the drug pushing drive mechanism 23 further includes a limit baffle 235, one end of which is located on the upper wall of the bottom 13 of the drug loading cartridge 1, and the other end is connected to the output end of the linear drive mechanism 231. Preferably, a sliding groove 131 is provided on the bottom 13 of the drug loading cartridge 1, and the limit baffle 235 slides in the sliding groove 131 to block or open the drug loading hole 12. Preferably, a rounded corner is provided at the end of the limit baffle 235 to facilitate the insertion of the limit baffle 235 between two adjacent explosives 4.

[0060] When the output end of the linear drive mechanism 231 drives the limit baffle 235 to move toward the medicine delivery opening 11, the limit baffle 235 blocks the medicine loading hole 12. At this time, the explosive 4 located below the medicine storage barrel 3 can be prevented from falling into the medicine loading barrel 1 and affecting the resetting of the medicine delivery push plate 22. When the output end of the linear drive mechanism 231 is reset, the limit baffle 235 opens the medicine loading hole 12. At this time, the explosive 4 located below the medicine storage barrel 3 falls onto the medicine delivery bottom plate 21 and the medicine delivery push plate 22 for the next medicine loading work.

[0061] Reference Figure 6 and attached Figure 7In one embodiment, the end of the medicine delivery bottom plate 21 protrudes upward and is provided with a stopper 211, and the end of the medicine delivery push plate 22 facing away from the medicine delivery opening 11 abuts against the stopper 211. Preferably, a matching groove 221 corresponding to the stopper 211 is provided on the medicine delivery push plate 22. In this embodiment, when the linear drive mechanism 231 drives the output end to reset, the output end of the linear drive mechanism 231 will drive the push plate driving rod 232, the medicine delivery push plate 22 and the second rod body 23312 to reset. At this time, the first rod body 23311 is not reset, that is, the elastic telescopic rod 2331 is extended. When the medicine delivery push plate 22 is reset to the end of the medicine delivery bottom plate 21, the matching groove 221 abuts against the stopper 211, and then the medicine delivery push plate 22 will drive the medicine delivery bottom plate 21 to reset, thereby improving the reset efficiency of the medicine delivery bottom plate 21 and thus improving the medicine loading efficiency.

[0062] In one of the embodiments, the position of the fixed baffle 2332 is adjustable. Preferably, a sliding mounting groove 2342 is provided on the bracket 234, and a mounting rod 23321 is provided on the fixed baffle 2332, which is detachably fastened to the sliding mounting groove 2342, so as to achieve the adjustable position of the fixed baffle 2332. In this embodiment, the moving distance of the medicine delivery base plate 21 can be adjusted, thereby adjusting the pushing distance of the explosive 4. The bracket 234 is provided with a scale 2341 at a position between the fixed baffle 2332 and the movable baffle 2333, so that the user can observe the pushing status of the explosive 4 conveniently.

[0063] In one embodiment, the linear drive mechanism 231 includes a rotation drive mechanism 2311, a screw rod 2312 connected to the rotation drive mechanism 2311, and a sliding plate 2313 threadedly matched with the screw rod 2312, and the sliding plate 2313 serves as an output end of the linear drive mechanism 231;

[0064] The second rod body 23312 and the push plate driving rod 232 are fixed to the sliding plate 2313. In this embodiment, the linear drive mechanism 231 adopts a linear module structure, which can ensure the movement stroke of the sliding plate 2313 and facilitate the sliding plate 2313 to be connected to the push plate driving rod 232, the second rod body 23312 and the limit baffle 235 at the same time. Preferably, the rotary drive mechanism 2311 is a rotary motor. In other embodiments, the linear drive mechanism 231 can also adopt a cylinder, a hydraulic cylinder or an electric cylinder.

[0065] In one embodiment, the charge barrel 1 is a circular barrel, the charge delivery bottom plate 21 is an arc-shaped plate, and the charge delivery push plate 22 is a circular plate. In this case, the limit baffle 235 is also an arc-shaped plate, and the explosive 4 is a cylindrical structure. Of course, when the explosive 4 is of other structures, the charge barrel 1, the charge delivery bottom plate 21 and the charge delivery push plate 22 can also be other adaptive structures to provide wrapped protection for the explosive 4.

[0066] In one of the embodiments, a limit ring 17 is provided on the outer wall of the charge cartridge 1, and a handle 18 is provided below the charge cartridge 1. The limit ring 17 is used to make the charge cartridge 1 abut against the outer wall of the charge hole when charging, and the handle 18 is convenient for the user to hold the automatic charging device for blasting. The cooperation between the limit ring 17 and the handle 18 can effectively improve the stability of the user when operating the charging.

[0067] Embodiment 2

[0068] Reference Figure 8 This embodiment is basically the same as the first embodiment, except that this embodiment does not have a drug storage cartridge 3. In this embodiment, the drug pushing drive mechanism 23 further includes a limit baffle 235, one end of which is located on the upper wall of the drug storage cartridge 1 and wraps around the upper end of the explosive 4, and the other end of the limit baffle 235 is connected to the output end of the linear drive mechanism 231;

[0069] During the process of the output end of the linear drive mechanism 231 driving the push plate drive rod 232 and the bottom plate drive mechanism 233 to move, the limit baffle 235 is always located above the explosive 4, thereby preventing the upper part of the explosive 4 from contacting the upper wall of the charging hole and causing friction damage, thereby improving the success rate of charging the explosive 4.

[0070] Embodiment 3

[0071] Reference Fig. 9 -Attached Fig.13 This embodiment is basically the same as the first embodiment, except that:

[0072] The medicine-loading barrel 1 is provided with an extended upper baffle 14 at one side of the medicine delivery opening 11, a sliding shielding plate 15 is provided inside the extended upper baffle 14, and also includes an elastic reset member 16 that drives the sliding shielding plate 15 to always move toward the barrel bottom 13;

[0073] After the linear drive mechanism 231 drives the limit baffle 235 to block the medicine feeding hole 12, the limit baffle 235 abuts against the sliding baffle 15 and pushes the sliding baffle 15 out of the medicine delivery opening 11. At this time, the sliding baffle 15 moves together with the medicine delivery bottom plate 21 and the medicine delivery push plate 22, thereby achieving all-round physical protection during the movement of the explosive 4. When the output end of the linear drive mechanism 231 is reset, the elastic reset member 16 drives the sliding baffle 15 to reset, thereby still keeping the medicine feeding hole 12 open to replenish the explosive 4. In this embodiment, the sliding distance of the sliding baffle 15 can be selected as needed, preferably consistent with the conveying distance of the medicine delivery bottom plate 21, and therefore only suitable for short-distance charging of explosives 4.

[0074] In this embodiment, by providing the sliding shielding plate 15 , it is possible to ensure all-round protection of the explosive 4 without affecting the blocking and opening of the charge feeding hole 12 .

In the embodiment with the medicine storage barrel 3, the explosive 4 is loaded into the charge barrel 1 through the reserve explosive 4 in the medicine storage barrel 3, and is directly loaded into the medicine delivery bottom plate 21 through the medicine loading hole 12;

[0077] S2, aligning the medicine delivery opening 11 of the medicine loading cartridge 1 with the medicine loading hole at the medicine loading destination. Preferably, the user holds the handle 18 and places the limiting ring 17 against the medicine loading hole to improve the stability of the medicine loading cartridge 1 during medicine loading;

[0079] S4, when the explosive 4 is one explosive 4 length away from the destination position in the charge hole, the movable baffle 2333 contacts the fixed baffle 2332, and the linear drive mechanism 231 continues to work. The second rod body 23312 compresses the elastic member in the elastic telescopic rod 2331 to shrink the elastic telescopic rod 2331, while the first rod body 23311 and the medicine delivery bottom plate 21 stop moving, and the push plate driving rod 232 drives the medicine delivery push plate 22 to continue moving, so that the medicine delivery push plate 22 pushes the explosive 4 into the destination position in the charge hole and separates from the medicine delivery bottom plate 21, completing the charging of the explosive 4;

[0080] S5, control the linear drive mechanism 231 to reset, so that the medicine feeding bottom plate 21, the medicine feeding push plate 22, the push plate driving rod 232 and the elastic telescopic rod 2331 are reset. In the embodiment with the medicine storage barrel 3 and the limit baffle 235, the limit baffle 235 is reset together to open the medicine feeding hole 12, and the explosives 4 located above and below the medicine storage barrel 3 fall into the medicine loading barrel 1, completing the replenishment of the explosives 4 in the medicine loading barrel 1. Then, the next charge work can be directly carried out, thereby improving the blasting efficiency.
