Description

Technical Field

[0001] This utility model belongs to the field of mining technology, specifically a charging device for mining blasting. Background Technology

[0002] Mines are areas that contain and exploit mineral resources, encompassing above-ground mining facilities and underground operating spaces. They extract various minerals using specialized equipment and technology, providing basic raw materials for industrial production, energy supply, and other fields. At the same time, it is essential to pay attention to safety and ecological protection during the mining process.

[0003] Firstly, during blasting operations in mines, operators frequently need to use charging equipment. While existing charging equipment has the basic function of filling and loading explosive casings, during actual use, operators need to drill holes of different sizes at different locations in the mine to place the explosives inside the mountain. However, the equipment can only clamp and fix explosive casings of the same size during loading. Therefore, when operators need to use it to clamp and fix explosive casings of different sizes, the device cannot meet the operational requirements, and thus needs to be improved. Utility Model Content

[0004] The purpose of this utility model is to address the above problems. This utility model provides a charging device for mining blasting, which has the advantage of wide application range.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a charging device for mining blasting, comprising a box body, a servo motor fixedly installed at the bottom of the inner surface of the box body, a rotating shaft fixedly sleeved at the other end of the output shaft of the servo motor, a convex block fixedly sleeved on the outer surface of the rotating shaft, two moving plates movably connected to the left and right sides of the bottom of the inner surface of the box body, the top ends of the two moving plates extending into the interior of the top of the box body and movably connected to the interior of the top of the box body, two clamping blocks fixedly installed at the top ends of the two moving plates, the two clamping blocks being the same size, and springs fixedly connected to the upper and lower ends of the opposite sides of the two moving plates, the other ends of the springs being fixedly connected to the inner surface of the box body.

[0006] As a preferred embodiment of this utility model, a connecting frame is fixedly connected to the rear of the top of the box body, and a rectangular block is movably connected to the top of the connecting frame. A funnel is fixedly installed in the front of the interior of the rectangular block. The top and bottom of the funnel pass through the rectangular block and extend to the outside of the top and bottom of the rectangular block, respectively. A limiting block is movably connected inside the connecting frame. The top of the limiting block passes through the connecting frame and extends to the bottom of the rectangular block and is fixedly connected to the bottom of the rectangular block.

[0007] As a preferred embodiment of this utility model, a drive motor is fixedly installed at the rear of the top of the rectangular block, and a rotating shaft is fixedly sleeved at the other end of the output shaft of the drive motor.

[0008] As a preferred embodiment of this invention, a long rod is fixedly sleeved on the outer surface of the rotating shaft, and a moving rod is hinged to the other end of the long rod.

[0009] As a preferred embodiment of this invention, the other end of the moving rod is hinged to a movable rod, and a round shaft is fixedly connected to the inside of the front of the movable rod. The bottom end of the round shaft passes through the movable rod and extends into the inside of the funnel.

[0010] As a preferred embodiment of this invention, the top of the rectangular block is fixedly connected to a guide rod located between the funnel and the drive motor. The top of the guide rod passes through the movable rod and extends to the outside of the top of the movable rod, and its outer surface is movably connected to the inside of the movable rod.

[0011] As a preferred embodiment of this utility model, a pneumatic cylinder is fixedly installed at the bottom of the back of the box body, and the top of the pneumatic cylinder extends to the rear of the bottom of the rectangular block and is fixedly connected to the bottom of the rectangular block.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] 1. This utility model incorporates a servo motor, a rotating shaft, a convex block, a moving plate, and a spring. When the operator starts the servo motor, the rotating shaft and the convex block rotate. At this time, the outer surface of the convex block presses against the opposing surfaces of the two moving plates, causing the two moving plates and the two clamping blocks to move in opposite directions. The spring is in a compressed state. Subsequently, the operator places an explosive casing of the corresponding size between the two clamping blocks and then runs the servo motor again, causing the rotating shaft and the convex block to return to their initial state. Due to the restoring effect of the spring, the two moving plates and the two clamping blocks move towards each other, thereby clamping and fixing the explosive casing, thus increasing the application range of this equipment.

[0014] 2. This utility model, by setting up a drive motor, a long rod, a moving rod, a movable rod, and a round shaft, allows the operator to start the drive motor, causing the rotating shaft and the long rod to rotate. This causes the moving rod to drive the movable rod and the round shaft to move upward, thereby releasing the round shaft from its obstruction of the explosives inside the funnel. Subsequently, the operator restarts the drive motor, causing the rotating shaft and the long rod to return to their initial state. This causes the movable rod to drive the round shaft to move downward, thereby causing the movable rod to re-obstruct the explosives inside the funnel. This process is repeated to control the amount of explosives fed into the funnel, thus avoiding waste of explosives. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. 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 charging device for mining blasting, including a box body 1. A servo motor 2 is fixedly installed at the bottom of the inner surface of the box body 1. A rotating shaft 3 is fixedly sleeved at the other end of the output shaft of the servo motor 2. A convex block 4 is fixedly sleeved on the outer surface of the rotating shaft 3. Motion plates 5 are movably connected to the left and right sides of the bottom of the inner surface of the box body 1. There are two motion plates 5. The top ends of the two motion plates 5 extend into the interior of the top of the box body 1 and are movably connected to the interior of the top of the box body 1. Clamping blocks 6 are fixedly installed at the top ends of the two motion plates 5. There are two clamping blocks 6. The two clamping blocks 6 are the same size. Springs 7 are fixedly connected to the upper and lower ends of the opposite sides of the two motion plates 5. The other end of the springs 7 is fixedly connected to the inner surface of the box body 1.

[0023] When the operator starts the servo motor 2, the rotating shaft 3 and the convex block 4 will rotate, causing the outer surface of the convex block 4 to squeeze and push the opposite surfaces of the two moving plates 5. This causes the two moving plates 5 to drive the two clamping blocks 6 to move in opposite directions. At this time, the four springs 7 will be in a compressed state. Then, the operator can place an explosive casing of a corresponding size between the two clamping blocks 6 according to the distance between them.

[0024] The box 1 is fixedly connected to the rear of the top end of the box body 1. A rectangular block 9 is movably connected to the top end of the connecting frame 8. A funnel 10 is fixedly installed inside the front of the rectangular block 9. The top and bottom ends of the funnel 10 pass through the rectangular block 9 and extend to the outside of the top and bottom ends of the rectangular block 9, respectively. A limiting block 19 is movably connected inside the connecting frame 8. The top end of the limiting block 19 passes through the connecting frame 8 and extends to the bottom end of the rectangular block 9 and is fixedly connected to the bottom end of the rectangular block 9.

[0025] The design of the funnel 10 allows the operator to load the explosive into the explosive casing through the funnel 10.

[0026] Among them, a drive motor 11 is fixedly installed at the rear of the top of the rectangular block 9, and a rotating shaft 12 is fixedly sleeved at the other end of the output shaft of the drive motor 11.

[0027] When the operator starts the drive motor 11, the rotating shaft 12 will rotate.

[0028] Among them, a long rod 13 is fixedly sleeved on the outer surface of the rotating shaft 12, and a moving rod 14 is hinged to the other end of the long rod 13.

[0029] When the rotating shaft 12 rotates, it will cause the long rod 13 to rotate as well.

[0030] The other end of the moving rod 14 is hinged to a movable rod 15, and a round shaft 16 is fixedly connected to the front of the movable rod 15. The bottom end of the round shaft 16 passes through the movable rod 15 and extends into the interior of the funnel 10.

[0031] The design of the circular shaft 16 allows it to block the explosives inside the funnel 10.

[0032] The top of the rectangular block 9 is fixedly connected to a guide rod 17 located between the funnel 10 and the drive motor 11. The top of the guide rod 17 passes through the movable rod 15 and extends to the outside of the top of the movable rod 15, and its outer surface is movably connected to the inside of the movable rod 15.

[0033] Due to the design of the guide rod 17, the movement of the movable rod 15 can be effectively limited.

[0034] Among them, a pneumatic cylinder 18 is fixedly installed at the bottom of the back of the box 1. The top of the pneumatic cylinder 18 extends to the rear of the bottom of the rectangular block 9 and is fixedly connected to the bottom of the rectangular block 9.

[0035] When the operator starts the pneumatic cylinder 18, the rectangular block 9 will move upward as a whole.

[0036] Working principle and usage process of this utility model:

[0037] First, the operator pours the explosive into the funnel 10, then starts the servo motor 2, causing the rotating shaft 3 and the convex block 4 to rotate. This causes the outer surface of the convex block 4 to press and push the opposing surfaces of the two moving plates 5, which in turn causes the two moving plates 5 to drive the two clamping blocks 6 to move in opposite directions. At this time, the spring 7 is compressed. Then, the operator places the explosive casing of the corresponding size between the two clamping blocks 6, and then starts the servo motor 2 again, causing the rotating shaft 3 and the convex block 4 to return to their initial state. Due to the elasticity of the spring 7, the two moving plates 5 and the two clamping blocks 6 move towards each other, thereby clamping and fixing the explosive casing.

[0038] Finally, the operator starts the pneumatic cylinder 18 and the drive motor 11. The operation of the pneumatic cylinder 18 causes the rectangular block 9 to move downwards, which in turn moves the bottom end of the circular shaft 16 to above the opening of the explosive casing. The operation of the drive motor 11 causes the rotating shaft 12 and the long rod 13 to rotate, which causes the moving rod 14 to drive the movable rod 15 and the circular shaft 16 to move upwards. This causes the circular shaft 16 to release its obstruction of the explosive inside the funnel 10, allowing the explosive to fall from the inside of the funnel 10 into the explosive casing. At this time, the operator starts the drive motor 11 again, which will cause the rotating shaft 12 and the long rod 13 to return to their initial state. This causes the movable rod 15 to drive the circular shaft 16 downwards, which in turn causes the movable rod 15 to block the explosive inside the funnel 10 again. This process is repeated to control the amount of explosive fed into the funnel 10.
