[0023] The following further describes the present utility model with reference to the drawings and specific embodiments. Embodiment

[0024] As Figures 1-3 shown, a blasting auxiliary explosive filling and ramming device includes:

[0025] The stuffing mechanism consists of a protective tube 1, an adjusting rod 4, a filling tube 6, and a telescopic rod 8. One end of the filling tube 6 is connected to the protective tube 1, and the other end of the filling tube 6 is connected to the inner rod of the adjusting rod 4. The inner rod of the adjusting rod 4 slides along the outer rod, driving the filling tube 6 to move back and forth along the inner wall of the protective tube 1. The telescopic rod 8 is inserted into the adjusting rod 4, and a push plate is provided at the end of the telescopic rod 8. The push plate extends into the filling tube 6.

[0026] The adjusting mechanism consists of a left arm rod 2 and a right arm rod 3. The left arm rod 2 and the right arm rod 3 are respectively arranged on both sides of the stuffing mechanism and can freely adjust the support angle. The bottoms of the left arm rod 2 and the right arm rod 3 are fixed by a connecting rod 5.

[0027] Specifically, a sealing gasket 7 is provided on the inner wall of the end of the protective tube 1 connected to the filling tube 6.

[0028] Specifically, the filling tube 6 is a detachable filling tube, which is connected to the inner rod of the adjusting rod 4 in a plug-and-play manner. The end of the telescopic rod 8 and the push plate are detachably connected, and the diameter of the push plate matches the inner diameter of the filling tube 6.

[0029] Specifically, the telescopic rod 8 adopts a button-type telescopic rod in the prior art. The lever handle of the telescopic rod 8 extends out of the adjusting rod 4, and the button is located on the lever handle. The telescopic rod 8 is divided into an outer rod and an inner rod. The inner wall of the outer rod is provided with empty holes, and an elastic steel sheet is embedded inside the inner rod. The protrusion of the steel sheet is exposed outside the inner rod and can be embedded with the empty holes of the outer rod to adjust the length.

[0030] Specifically, the left arm rod 2 and the right arm rod 3 have the same structure and are both composed of a cross bar and two vertical bars. The two vertical bars on the same side are respectively rotatably connected to the protective tube 1 and the outer rod of the adjusting rod 4. The two cross bars at the bottom are connected by a connecting rod 5.

[0031] When using the above device, fill the filling tube 6 with explosives and fix the device at the position where charging is required. Use the adjusting rod 4 to adjust the filling tube 6, and finally press the telescopic rod 8 to accurately inject the explosives into the filling tube to complete the work of charging and stuffing. The specific operation is as follows:

[0032] Before starting the charging operation, a detailed inspection and preparation of the entire device must be carried out, including ensuring the integrity and cleanliness of the main body of the filling tube 6, as well as the operability and accuracy of the adjusting rod 4, the left arm rod 2, and the right arm rod 3. During the specific operation, first, align the protective tube 1 with the blast hole position where charging is required by adjusting the left arm rod 2 and the right arm rod 3. Insert one end of the filling tube 6 tightly into the inner rod of the adjusting rod 4. A detachable plug-in connection can also be adopted between the telescopic rod 8 inside the adjusting rod 4 and the push plate. At this time, the telescopic rod 8 passes through the filling tube 6 and is connected to the push plate, that is, one end of the filling tube 6 is fixed. The operator precisely loads a predetermined amount of explosive charge into the filling tube 6, and then connects the filling tube 6 to the protective tube 1. After the filling tube 6 is fixed, first push the adjusting rod 4, and its inner rod drives the filling tube 6 to move forward along the protective tube 1 to the blast hole. Then press the button on the telescopic rod 8 to control the elastic steel sheet to form a sliding lock. When the button is pressed, the inner rod of the telescopic rod 8 is squeezed downward. At this time, the protrusion on the steel sheet separates from the hole on the outer rod of the telescopic rod 8, and the inner rod automatically slides down. When it slides to an appropriate distance, release the button so that the protrusion fits into the hole of the outer rod to fix the telescopic rod 8. With the adjustment of the telescopic rod 8, the explosive charge in the filling tube 6 accurately enters the blast hole under the action of the push plate, completing the work of charging and tamping. After all operations are completed, strict safety inspections and confirmations must be carried out. This includes checking whether the depth and position of the charge are correct, and ensuring that there are no potential safety hazards in the device and the main body of the filling tube.

[0033] The maintenance of the device is also very convenient. Pull out the inner rod of the adjusting rod 4 from the filling tube 6. When the adjusting rod 4 and the filling tube 6 are separated, the telescopic rod 8 and the push plate are also separated. Then take out the other end of the filling tube 6 from the protective tube 1, so as to remove the filling tube 6 as a whole, which is convenient for inspecting and cleaning the filling tube 6.
