[0002] A charging rod for blasting operations refers to a tool used for packaging and transporting explosives. It is usually made of metal and has a cylindrical shape. There is usually an opening at the upper end of the charging rod for loading explosives into it. There is usually a sealing device at the bottom of the charging rod to ensure that the explosives do not leak accidentally. For example, the utility model patent with the authorization announcement number CN215261484U proposes a charging rod for blasting operations. It includes an outer cylinder and an inner cylinder arranged in the inner cavity of the outer cylinder, a movable baffle is arranged at one end of the outer cylinder, and the movable baffle is connected to the outer cylinder by a spring, and a push rod is arranged at the end of the inner cylinder away from the movable baffle, and the outer cylinder includes a charging barrel and a barrel cover, and the charging barrel and the barrel cover are rotatably connected by a hinge, and permanent magnets are arranged on the charging barrel and the barrel cover.

[0003] The existing charging rod needs an opening at the end. When the charging rod is inserted into the blasting hole, the opening faces downward, causing the explosive in the charging rod to slide out. The cover also affects the discharge of the explosive. In addition, the charge amount of the charging rod is relatively fixed, which has certain limitations for different amounts of explosives. Therefore, it needs to be improved. Summary of the invention

[0004] The utility model aims to provide a charging rod for blasting operations, which solves the problem that the end of the existing charging rod needs to have an opening. When the charging rod is inserted into the blasting hole, the opening faces downward, causing the explosive in the charging rod to slide out, and the cylinder cover affects the discharge of the explosive. At the same time, it solves the problem that the charging amount of the charging rod is relatively fixed and there are certain limitations for the needs of different amounts of explosives.

[0005] In order to achieve the above-mentioned purpose, the utility model provides a charging rod for blasting operations, including a charging cartridge, two cartridge covers are installed on the top of the charging cartridge through a torsion spring, and the cartridge covers are in contact with each other, the upper end of the cartridge cover is fixedly connected with a connecting ring, the outer wall of the charging cartridge is fixedly connected with a hollow shell, the lower end of the hollow shell is slidably connected with a sliding rod, one end of the sliding rod located on the inner side of the hollow shell is fixedly connected with a connecting block, and the connecting block is slidably connected to the inner side of the hollow shell, the upper end of the connecting block is fixedly connected with a connecting rope, the connecting rope passes through the hollow shell and is slidably connected to the hollow shell, the end of the connecting rope is fixedly connected to the connecting ring, the inner lower part of the charging cartridge is fixedly connected with a fixing plate, the interior of the fixing plate is installed with an adjusting rod through a bearing, the upper section of the rod body of the adjusting rod is connected with a threaded sleeve through a thread, the top of the threaded sleeve is fixedly connected with a pad, and the pad is slidably connected to the inner side of the charging cartridge.

[0006] The principle of the utility model is that when in use, firstly, the slide bars are pulled toward each other through the pull ring, and the slide bars pull the connecting block and compress the spring, at which time the connecting block pulls the barrel cover through the connecting rope and opens it, and then the explosive is filled in the charge barrel and supported by the cushion block, and then the pull ring is released, and the barrel cover is closed under the action of the torsion spring, and when the explosive is filled in the blasting hole, the barrel cover can be opened by pulling the pull ring again, and then the explosive is discharged immediately;

[0007] In addition, by turning the adjusting rod with the knob, the adjusting rod can control the position of the pad in the charge cartridge through relative threaded movement with the threaded sleeve and the guidance of the guide rod and the guide groove, thereby meeting the purpose of loading different amounts of explosives.

[0008] The beneficial effect of the utility model lies in that the barrel cover is installed on the end of the charge barrel by a torsion spring, and then a hollow shell is arranged on the outside of the charge barrel, a connecting block elastically supported by a spring is arranged on the inside of the hollow shell, and the connecting block is connected to the barrel cover by a connecting rope. In this way, by pulling the sliding rod at the bottom of the connecting block, the connecting rope can be pulled, and then the barrel cover is opened, without affecting the discharge of explosives.

[0009] By arranging an adjustment mechanism consisting of a knob, a guide rod, a guide groove, an adjustment rod and a threaded sleeve on the inner side of the charge cartridge, the position of the cushion block in the charge cartridge can be controlled by the adjustment mechanism, thereby meeting the purpose of filling different amounts of explosives.

[0010] Furthermore, a pull ring is fixedly connected to the lower end of the slide bar, and the pull ring is made of stainless steel. The setting of the pull ring facilitates pulling the connecting rope.

[0011] Furthermore, a spring is sleeved outside the rod body of the slide rod, one end of the spring is fixedly connected to the connecting block, and the other end of the spring is fixedly connected to the inner surface of the hollow shell. Through the arrangement of the spring, elastic force can be applied to the connecting block and the slide rod.

[0012] Furthermore, a guide wheel is arranged on the outer wall of the cartridge and located above the hollow shell, and the guide wheel is in contact with the connecting rope. The setting of the guide wheel has a certain guiding effect on the connecting rope.

[0013] Furthermore, a knob is fixedly connected to the lower end of the adjusting rod, and the knob is made of plastic. The setting of the knob makes it easy to rotate the adjusting rod.

[0014] The outer side of the threaded sleeve is fixedly connected with a guide rod, the inner wall of the cartridge is fixedly connected with a guide groove, and the guide groove is further slidably connected with the guide rod. The arrangement of the guide rod and the guide groove has a guiding effect on the relative threaded movement between the threaded sleeve and the adjusting rod.

[0015] Furthermore, the cushion block is in a round block shape and is made of rubber material. The cushion block has a supporting effect on the explosive in the cartridge. BRIEF DESCRIPTION OF THE DRAWINGS
