Abstract
Description
Technical Field
[0001] This utility model relates to the field of blasting device technology, and in particular to an efficient charging auxiliary device for blasting operations. Background Technology
[0002] Blasting engineering refers to a construction method that uses explosives to excavate earth and rock, and to demolish or destroy foundations, buildings, and structures. There are many types of explosives; those commonly used in construction engineering include ammonium nitrate explosives, nitroglycerin explosives, and black powder. Before blasting, explosives are typically placed in paper tubes, immersed in wax, and sealed to form explosive cartridges. Because the amount of explosives required for blasting is related to the hole spacing, row spacing, and borehole depth, the diameter and length of the explosive cartridges vary depending on the blasting project, and according to regulations, the cartridges need to be fabricated on-site.
[0003] In existing blasting operations, explosive cartridges are typically made by manually weighing and loading them. Each time explosives are added to a paper tube, the appropriate weight of explosives needs to be weighed, resulting in low loading efficiency and affecting the efficiency of blasting operations. Utility Model Content
[0004] The purpose of this utility model is to provide an efficient charging auxiliary device for blasting operations, which can automatically add explosives to the charging paper tube and monitor the weight change of the charging paper tube in real time, so that the charging will automatically stop when the weight of the explosives in the charging paper tube reaches the standard, thereby improving the charging efficiency.
[0005] To achieve the above objectives, a high-efficiency charging auxiliary device for blasting operations is provided, comprising a workbench. Two first electric push rods are symmetrically fixedly connected to the upper end of the workbench. Connecting plates are fixedly connected to the upper ends of the two first electric push rods respectively. A charging hopper is provided between the two first electric push rods, and the outer ends of the charging hopper are fixedly connected to the side ends of the connecting plates on the two first electric push rods respectively. A discharging mechanism is fixedly connected to the lower end of the charging hopper, and the discharging mechanism communicates with the bottom of the charging hopper. A placement mechanism is fixedly connected to the lower end of the workbench, and the upper end of the placement mechanism extends through to the workbench. At the upper end of the worktable, the placement mechanism includes a charge paper tube, with its upper end extending above the worktable. The output end of the unloading mechanism is located directly above the charge paper tube. A limiting mechanism is installed at the upper end of the worktable, with the placement mechanism situated in the middle of the limiting mechanism. The upper end of the charge paper tube passes through the middle of the limiting mechanism and extends to its upper end. Support rods are installed at the four corners of the lower end of the worktable, with a support frame fixedly connected to the lower end of each support rod. The support rods are located at the four upper corners of the support frame, and casters are fixedly connected to the four lower corners of the support frame. This system automatically adds explosives to the charge paper tube and monitors its weight changes in real time, automatically stopping loading once the explosive weight in the charge paper tube reaches the target, thus improving loading efficiency.
[0006] According to the aforementioned efficient charging auxiliary equipment for blasting operations, the placement mechanism comprises a weighing device, a second electric push rod, and a placement cylinder. The placement cylinder is fixedly connected to the lower end of a workbench, and its upper end has an opening that penetrates the workbench. The output end of the unloading mechanism is located above the middle of the placement cylinder. The second electric push rod is fixedly connected to the lower end of the placement cylinder, and its piston rod extends upward through the middle of the placement cylinder and is slidably connected to it. The weighing device is fixedly connected to the upper end of the piston rod of the second electric push rod. The charging paper tube is placed into the placement cylinder through the upper opening, with the lower end of the charging paper tube located above the weighing device. The placement cylinder is used to place the charging paper tube, preventing it from tipping over during the charging process. Simultaneously, the weighing device monitors the weight change of the charging paper tube. The second electric push rod changes the height of the weighing device within the placement cylinder, causing the weighing device to push the top of the charging paper tube out of the placement cylinder, facilitating the charging of charging paper tubes of different lengths.
[0007] According to the aforementioned efficient charging auxiliary equipment for blasting operations, the limiting mechanism comprises a fixed plate, a clamping block, a bidirectional screw, a knob, and a sliding column. Two fixed plates are fixedly connected to the upper end of the worktable. Two clamping blocks are symmetrically arranged between the two fixed plates, with the lower end of the clamping plate slidably connected to the upper end of the worktable. The placement cylinder is located in the middle between the two clamping blocks. The bidirectional screw and the sliding column are respectively located on both sides of the placement cylinder, and the bidirectional screw and the sliding column sequentially penetrate the fixed plate and the clamping block. The bidirectional screw is rotatably connected to the two fixed plates and threadedly connected to the two clamping blocks. The two clamping blocks are symmetrically arranged in the two thread directions of the bidirectional screw. The sliding column is fixedly connected to the two fixed plates and slidably connected to the two clamping blocks. The knob is fixedly connected to one end of the bidirectional screw, and the charging paper tube is located between the two clamping blocks. The knob drives the bidirectional screw to rotate and, in conjunction with the sliding column, changes the distance between the two clamping blocks, causing the clamping blocks to contact the outer surface of the top of the drug-filled paper tube, thus straightening the drug-filled paper tube.
[0008] According to the aforementioned high-efficiency charging auxiliary equipment for blasting operations, the unloading mechanism comprises a stepper motor, a spiral blade, and a conveying pipe. The conveying pipe is fixedly connected to the lower end of the charging hopper, and its top end communicates with the lower end of the charging cylinder. One end of the conveying pipe has an opening that extends to the upper middle part of the placement cylinder and faces downwards towards it. The stepper motor is fixedly connected to the end of the conveying pipe away from its own opening, and its output end passes through the conveying pipe and is rotatably connected to it. The spiral blade is disposed within the conveying pipe, and its outer surface is rotatably connected to the inner wall of the conveying pipe. The shaft of the spiral blade is fixedly connected to the output end of the stepper motor. The stepper motor controls the rotation of the spiral blade, discharging the explosive powder in the charging hopper through the conveying pipe, thereby adding explosive to the charging cylinder.
[0009] According to the aforementioned high-efficiency charging auxiliary equipment for blasting operations, a storage battery is fixedly connected to the lower center of the workbench, and a controller is fixedly connected to the upper end of the workbench. The storage battery provides power for the operation of the device, and the controller facilitates operator control of the device.
[0010] According to the aforementioned high-efficiency charging auxiliary equipment for blasting operations, an anti-static chain is connected to the outer surface of the charging hopper, with the end of the anti-static chain furthest from the charging hopper placed on the ground. The anti-static chain is used to eliminate static electricity on the surface of the charging hopper.
[0011] According to the aforementioned high-efficiency charging auxiliary equipment for blasting operations, the surface of the placement cylinder is provided with an opening slot for the wiring of the weighing device to pass through. The opening slot on the surface of the placement cylinder prevents the wiring of the weighing mechanism from being affected when the height of the weighing device changes.
[0012] According to the aforementioned high-efficiency charging auxiliary equipment for blasting operations, the inner diameter of the opening of the feeding pipe is 16mm. This makes the opening diameter of the feeding pipe much smaller than the inner diameter of a conventional charging paper tube, facilitating the insertion of the opening end of the feeding pipe into the charging paper tube for charging.
[0013] The above scheme has the following advantages: the placement mechanism places the explosive paper tubes and monitors their weight; the unloading mechanism conveys the explosive powder from the hopper into the explosive paper tubes; and the loading automatically stops when the weight of the explosive paper tubes reaches the target, thus improving loading efficiency and accuracy. The second electric push rod in the placement mechanism allows the top of the explosive paper tubes to extend above the worktable when loading explosive paper tubes of different lengths, facilitating loading by the unloading mechanism.
[0014] Additional aspects and advantages of this invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Attached Figure Description

The knob 18 drives the bidirectional screw 17 to rotate and cooperates with the sliding column 19 to change the distance between the two clamping blocks 16, so that the clamping blocks 16 contact the outer surface of the top of the medicine-filled paper tube 14, thus straightening the medicine-filled paper tube 14. The upper end of the medicine-filled paper tube 14 passes through the middle of the limiting mechanism 9 and extends to the upper end of the limiting mechanism 9.
