For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0023] The present invention discloses a blasting charge device for use in mine blasting operations. Figures 1 to 4The blasting charge device includes a medicine feed barrel 2, a quantitative component 3 and a power component 4, and the power component 4 acts on the quantitative component 3 to make it move away from or close to the medicine feed barrel 2. Among them, the power component 4 is fixedly connected to the quantitative component 3 through a connecting rod 11. The quantitative component 3 includes a medicine box 36, a slider 33, a fixed plate 35 and a fixed rod 34, and the quantitative component 3 is connected to the medicine feed barrel 2, and the slider 33 and the medicine box 36 are slidably arranged under the medicine feed barrel 2. The power component 4 is connected to the fixed rod 34, drives the medicine box 36 to move closer to or away from the fixed rod 34, and after a certain amount of explosives falls into the medicine box 36 from the medicine feed barrel 2, the medicine box 36 is pushed away from the medicine feed barrel 2 to prevent the explosives from continuing to enter the medicine box 36, thereby achieving quantitative measurement of the explosives in the medicine box 36. The slider 33 and the fixed plate 35 form a storage space (not shown in the figure), and a medicine delivery hole (not shown in the figure) opposite to the medicine box entrance (not shown in the figure) is formed on the slider 33. The medicine box 36 is connected to the slider 33 and is accommodated in the storage space. After a certain amount of explosives falls into the medicine box 36, the fixed rod 34 pushes the medicine box 36 to leave the storage space. When the medicine box 36 is close to the fixed rod 34, the medicine delivery hole is connected to the exit of the medicine feed barrel 2 (not shown in the figure). At this time, the explosive passes through the medicine delivery hole and falls from the medicine feed barrel 2 into the medicine box 36. When the medicine box 36 is away from the fixed rod 34, the medicine delivery hole is no longer connected to the medicine feed barrel 2 and the medicine box 36, and the slider 33 blocks the exit of the medicine feed barrel 2, thereby ensuring that the explosives in the medicine feed barrel 2 will not leak due to the movement of the medicine box 36, thereby causing safety hazards.

[0024] Further, in some embodiments, the power assembly 4 further includes a connecting plate 41, a push rod 47, a rotating disk 43 and a transmission rod 45, and the push rod 47, the rotating disk 43 and the transmission rod 45 are all installed on the connecting plate 41. The rotating disk 43 is connected to a driving motor 49, and the driving motor 49 is installed on the other side of the connecting plate 41. The connecting plate 41 is provided with a bracket plate 48 for accommodating the driving motor 49. The two ends of the transmission rod 45 are respectively connected to the rotating disk 43 and the push rod 47, and the driving motor 49 is connected to the rotating disk 43 through the first rotating shaft 42 passing through the connecting plate 41, and under the action of the driving motor 49, the rotating disk 43 rotates to drive the push rod 47 to move horizontally, so that the push rod 47 drives the medicine box 36 to approach or move away from the medicine inlet barrel 2. Among them, the two ends of the transmission rod 45 are respectively provided with a second transmission shaft 44 and a third transmission shaft 46, so as to ensure that the rotation of the rotating disk 43 can be transmitted to the push rod 47 through the transmission rod 45, and the rotation force is converted into a horizontal force, so as to realize the horizontal movement of the push rod 47.

[0025] It can be understood that the push rod 47 is provided with a fixed structure fixedly connected to the medicine box 36 to ensure a fixed relationship between the push rod 47 and the medicine box 36. After the turntable 43 drives the push rod 47 to move horizontally to push the medicine box 36 away from the accommodating space, the medicine box 36 can still be brought back to the accommodating space by reverse horizontal movement for the next explosive filling.

[0026] In some embodiments, the power assembly 4 also includes a limit member 9, which is fixedly connected to the connecting plate 41. The push rod 47 extends into and is clamped on the limit member 9 to ensure that the push rod 47 can always maintain horizontal movement under the drive of the drive motor 49 and the turntable 43, thereby avoiding the push rod 47 from driving the medicine box 36 to deviate, which on the one hand will cause a waste of electricity from the drive motor 49; on the other hand, when the moving direction of the push rod 47 deviates downward, it will generate downward pressure on the medicine box 36 and move the medicine box 36 against the fixed plate 35, causing unnecessary wear on the medicine box 36.

[0027] It can be understood that the limit member 9 includes a buffer plate 91 and a limit plate 92, wherein the push rod 47 is located in the limit plate 92, the buffer plate 91 is arranged between the limit plate 92 and the connecting plate 41, the connecting plate 41 is installed on the buffer plate 91, and the buffer plate 91 is installed on the connecting plate 41 by fixing screws 93 to avoid the limit plate 92 being directly connected to the connecting plate 41. When the push rod 47 moves in the limit plate 92, the fixing parts between the limit plate 92 and the connecting plate 41 cause wear on the push rod 47, thereby affecting the service life of the entire power assembly 4.

[0028] Furthermore, the limiting member 9 further includes a fixed seat 94, which is disposed in the limiting plate 92 and is mounted on the push rod 47. The push rod 47 performs horizontal movement in the fixed seat 94, further limiting the movement direction of the push rod 47 when it performs horizontal movement driven by the drive motor 49 and the turntable 43. In some embodiments, a sliding groove (not shown) and a sliding block (not shown) may be provided between the fixed seat 94 and the limiting plate 92, and the fixed seat 94 performs horizontal movement together with the push rod 47 in the limiting plate 92.

[0029] In some embodiments, the dosing component 3 also includes a slide rail 32, which is arranged at both ends of the fixed rod 34, and the slider 33 is arranged parallel to the fixed rod 34. The slider 33 slides along the slide rail 32, ensuring that the movement trajectory of the medicine box 36 is always relatively stable when it is close to the fixed rod 34 for filling or away from the fixed rod 34 for delivering medicine, thereby avoiding unnecessary collisions of the explosives in the medicine box 36 during transportation to create safety hazards.

[0030] Further, in some embodiments, the blasting charge device further includes a support plate 31, including a through hole, which is disposed between the medicine feed barrel 2 and the medicine box 36, and is used to support the medicine feed barrel 2. The support plate 31 is fixedly connected to the medicine feed barrel 2 and installed above the slide rail 32. When the medicine box 36 is close to the fixed rod 34 for charging, the through hole coincides with the circular groove, and the explosive can fall from the medicine feed barrel 2 into the medicine box 36 until a certain amount of explosive enters the medicine box 36, and the push rod 47 pushes the medicine box 36 away from the fixed rod 34 for delivering the medicine. At this time, the circular groove on the slider 33 no longer coincides with the through hole, and the upper surface of the slider 33 abuts against the through hole, so as to achieve the closure of the medicine feed barrel 2 and avoid the leakage of explosives from the medicine feed barrel 2 to cause safety hazards.

[0031] Since the use scenario of the blasting charge device is often to deliver medicine to a deep hole on the ground, in order to further speed up the efficiency of the entire quantitative assembly 3 in delivering medicine, in some embodiments, the medicine box 36 includes a reversible cover plate 38. When the medicine box 36 is away from the fixed rod 34, the cover plate 38 opens the medicine box 36, so that the explosives in the medicine box 36 can automatically fall into the deep hole on the ground. When the medicine box 36 is close to the fixed rod 34, the cover plate 38 covers the medicine box 36, closes the medicine box 36, and sends it to the accommodating space to receive the explosives in the medicine barrel 2. Further, a first rotating shaft 37 is provided at the connection between the cover plate 38 and the medicine box 36. The cover plate 38 opens or closes the medicine box 36 through the first rotating shaft 37, and the first rotating shaft 37 is provided on the side of the medicine box 36 close to the fixed rod 34, ensuring that when the medicine box 36 approaches the fixed rod 34 along with the slide rail 32, the cover plate 38 can be automatically retracted and closed under the action of the fixed plate 35.

[0032] It can be understood that when the medicine box 36 is out of the accommodating space and coincides with the deep hole on the ground, the medicine box 36 no longer needs the cover plate 38. The cover plate 38 forming the accommodating space can play a certain sealing role. When the medicine box 36 is out of the accommodating space, the explosives in the medicine box 36 fall directly and enter the deep hole on the ground.

[0033] In some embodiments, the explosive charge device further includes a base plate 1 and support legs 5 for supporting the medicine feed barrel 2. The support legs 5 are connected to the base plate 1 and supported on the ground of the construction area. The base plate 1 and the support legs 5 together form a support structure to support the entire blasting charge device so that it can be stably supported in the construction area, thereby ensuring that the medicine feed barrel 2 filled with explosives can always remain stable in the construction area, avoiding the shaking or collapse of the medicine feed barrel 2, which may cause leakage of explosives and cause unnecessary damage.

[0034] Since it is often necessary to load explosives into multiple deep holes when blasting in a mining area, in some embodiments, the blasting loader also includes universal wheels 6 connected to the support legs 5, so that the entire blasting loader can be moved more freely in the construction area. The staff can push the entire blasting loader to move, thereby speeding up the efficiency of loading deep holes in different locations.

[0035] It can be understood that in order to further ensure the stability of the medicine feed barrel 2 on the base plate 1, in some embodiments, the blasting charge device further includes a clamping plate 10, which is mounted on the medicine feed barrel 2. The two ends of the support rod 8 are respectively connected to the top of the medicine feed barrel 2 and the base plate 1, and a connecting piece 7 is provided on the top of the medicine feed barrel 2 for fixing the support rod 8. The middle part of the support plate 31 abuts against the clamping plate 10, and the two together fix and limit the medicine feed barrel 2 to ensure that the medicine feed barrel 2 is stably fixed on the base plate 1.

[0036] Since the working environment of the blasting charge device is usually a mining area, in order to ensure that the explosives in the medicine feed barrel 2 can also work normally in a humid or dusty environment, in some embodiments, the blasting charge device also includes a protective shell 12, which is arranged around the base plate 1 and forms a receiving chamber together with the base plate 1. The medicine feed barrel 2 is installed in the receiving chamber, and the receiving chamber is relatively sealed, which further isolates the explosives in the medicine feed barrel 2 from the construction environment to prevent the explosives in the medicine feed barrel 2 from being affected by the humid environment or dust. A push plate 13 is also provided on the upper part of the protective shell 12, and the push plate 13 covers the protective shell 12 and the base plate 1 to achieve the closed receiving chamber of the medicine feed barrel 2. A handle 14 is also provided on the push plate 13. When it is necessary to add explosives to the medicine feed barrel 2, the staff can pull the handle 14 to open the push plate 13 to complete the loading of the explosives.

[0037] It will be apparent to those skilled in the art that the invention is not limited to the details of the exemplary embodiments described above and that the invention can be implemented in other specific forms without departing from the spirit or essential features of the invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of the invention is defined by the appended claims rather than the foregoing description, and it is intended that all variations falling within the meaning and scope of the equivalent elements of the claims be included in the invention. Any reference numeral in a claim should not be considered as limiting the claim to which it relates.
