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.

[0033] Please see Figures 1-6 The present invention provides the following technical solution: a tunnel smooth blasting charge precision positioning device, comprising an installation pipe 1 and a holding pipe 2, wherein the holding pipe 2 is disposed inside the installation pipe 1;

[0034] In Example 1, both the holding tube 2 and the mounting tube 1 are designed with a semi-circular arc shape, and the outer diameter of the holding tube 2 is smaller than the inner diameter of the mounting tube 1. Both the holding tube 2 and the mounting tube 1 have an open structure on the right side. A movement control mechanism is provided on the outside of the holding tube 2 to control the movement of the holding tube 2 inside the mounting tube 1. A baffle 3 is fixed on the left side of the holding tube 2, and an indicator rod 14 is provided on the left side of the baffle 3 to measure the filling depth of the medicine. An automatic shielding mechanism is provided on the right side of the holding tube 2. After the holding tube 2 rotates, the automatic shielding mechanism automatically releases the shielding of the medicine, allowing the holding tube 2 to be pulled out from the outside of the medicine.

[0035] In use, the holding tube 2 can be moved to the end of the mounting tube 1, and the explosive to be used can be placed into the holding tube 2. Then, the holding tube 2 can be moved back into the mounting tube 1, and the mounting tube 1 can be inserted into the explosive filling hole so that the right end of the mounting tube 1 contacts the bottom of the hole. The filling position of the explosive can be controlled by moving the holding tube 2. With the help of the marker rod 14, the depth position of the holding tube 2 can be determined. The filling position of the explosive can be precisely controlled by reading the value, thus improving the positioning accuracy.

[0036] In Embodiment 2, based on Embodiment 1, an auxiliary disk 11 is provided on the left side of the baffle 3. The auxiliary disk 11 and the holding tube 2 are rotatably connected. A guide block 12 is fixed on the surface of the auxiliary disk 11, and a guide groove 13 is provided on the outer side of the guide block 12. The guide groove 13 is opened on the inner side of the mounting tube 1, and the guide block 12 and the guide groove 13 form a left-right sliding structure. An indicator rod 14 is fixed on the left side of the auxiliary disk 11, and an indicator line is provided on the surface of the indicator rod 14. The left end of the indicator rod 14 penetrates the left side surface of the mounting tube 1. A connector 17 is fixed on the right side of the auxiliary disk 11. The right end of the connector 17 has an enlarged structure design, and an annular groove 18 is provided on the outer side of the connector 17. The annular groove 18 is opened on the left side of the baffle 3, and the annular groove 18 and the connector 17 form a sliding connection.

[0037] The auxiliary plate 11 can move horizontally within the installation tube 1 through the connection of the guide block 12 and the guide groove 13. When the container tube 2 is rotated, the baffle 3 can rotate outside the connector 17 through the annular groove 18, so that the auxiliary plate 11 can remain stable. At the same time, the auxiliary plate 11 can move horizontally synchronously with the container tube 2, so that the marker rod 14 can accurately mark.

[0038] Example 3, based on Example 2, discloses a movement control mechanism including a push plate 8, a second spring 9, and a control shaft 10. The push plate 8 is located on the left side of the holding tube 2, and a left-right sliding structure is formed between the push plate 8 and the holding tube 2. The second spring 9 is located on the left side of the push plate 8 to provide a rightward thrust to the push plate 8. The control shaft 10 is fixed on the left side of the push plate 8, and the horizontal center line of the control shaft 10 coincides with the horizontal center line of the holding tube 2. The left end of the control shaft 10 penetrates the left side surface of the mounting tube 1. A transmission block 15 is fixed below the push plate 8, and a sliding groove 16 is provided on the outer side of the transmission block 15. The block 15 and the slide 16 form a left-right sliding structure. The automatic shielding mechanism includes a blocking block 4, a first spring 5, a storage groove 6, and an adsorption strip 7. The blocking block 4 is set on the right side of the holding tube 2 and forms a vertical sliding structure between the holding tube 2 and the holding tube 2. The blocking block 4 is made of magnetic material. The first spring 5 is set on the outside of the blocking block 4 to provide tension to the blocking block 4 so that it shields the medicine in the holding tube 2. The storage groove 6 is opened on the inside of the mounting tube 1, and the right end of the storage groove 6 is designed with an inclined structure. The adsorption strip 7 is fixed inside the storage groove 6 to attract the blocking block 4, so that the blocking block 4 enters the inside of the storage groove 6.

[0039] When it is necessary to put the medicine down, the marker rod 14 can be positioned to prevent the subsequent horizontal movement of the holding tube 2. Then, the push plate 8 is controlled by the control shaft 10 to drive the holding tube 2 to rotate, so that the medicine falls from the holding tube 2. At the same time, the blocking block 4 moves to the bottom of the storage groove 6, and the adsorption strip 7 attracts the blocking block 4, so that the blocking block 4 moves upward and releases the obstruction to the medicine. Then, the installation tube 1 can be pulled to take it out of the hole. The medicine will stay in the hole and will not move with the movement of the installation tube 1 and the holding tube 2, thus completing the filling of the medicine.
