[0029] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0030] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or a point connection; it can be a direct connection or an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0031] Combine the following Figure 1-Figure 8 An automatic loading system for explosive bombs according to an embodiment of the present invention is described, comprising: a tube feeder 1, a guide tube 2, a drug delivery tube 3 and a magazine 4, the drug delivery tube 3 being connected to the tube feeder 1, one end of the drug delivery tube 3 being inserted into the guide tube 2, a first opening 21 being provided at the bottom of the guide tube 2, a second opening 41 being provided at the top of the magazine 4, and the top of the magazine 4 being inserted into the first opening 21, an elastic device for ejecting explosive bombs 5 being provided at the bottom of the magazine 4, the tube feeder 1 being used for pushing the drug delivery tube 3 through the first opening 21, the drug delivery tube 3 being used for pushing the explosive bomb 5 ejected from the second opening 41 of the magazine 4 along the length direction of the guide tube 2, an isolation spring 8 being provided in the guide tube 2, one end of the isolation spring 8 being connected to one end of the guide tube 2, and the isolation spring 8 being sleeved on the outside of the drug delivery tube 3, so that the drug delivery tube 3 is isolated from the explosive bomb 5 in the magazine 4.

[0032] Specifically, the tube delivery device 1 is used to drive the drug delivery tube 3 to be pushed along the length direction of the guide tube 2. The tube delivery device 1 can use a hydraulic motor or a servo motor to provide driving force. When the tube delivery device 1 is working, it drives the drug delivery tube 3 to be pushed or pulled back along the length direction of the guide tube 2. The tube delivery device 1 is connected to the tail of the guide tube 2. Figure 1 As shown, when the tube feeder 1 stops working, the magazine 4 can be installed on the guide tube 2 through the first opening 21. Due to the elastic force of the elastic device, the detonating bomb 5 on the top of the magazine 4 is pushed out from the second opening 41 and enters the guide tube 2. Figure 2 As shown, the tube feeder 1 is turned on, the drug delivery tube 3 is driven to advance and contact with the tail of the explosive bomb 5 in the guide tube 2, the tail of the explosive bomb 5 is inserted into the drug delivery tube 3, and the drug delivery tube 3 and the explosive bomb 5 move along the guide tube 2 together until they are out of the guide tube 2 and enter the blast hole. When reaching the predetermined position, the charging system is started, the explosive is sprayed out from the drug delivery tube 3 and the explosive bomb 5 is pushed out and placed in the predetermined position in the hole, completing the automatic loading of a single explosive bomb 5, and at the same time starting the tube withdrawal action of the tube feeder 1 to complete the loading while withdrawing the tube. After the loading is completed, the drug delivery tube 3 is reset, and the next automatic loading process of the explosive bomb 5 is started.

[0033] When the tube delivery device 1 is not turned on, the drug delivery tube 3 is in the starting position, and the barrier spring 8 is in a compressed state. When the tube delivery device 1 is turned on, the drug delivery tube 3 is pushed to move along the direction of the guide tube 2. At this time, the barrier spring 8 is in a free state or a stretched state. At this time, due to the isolation effect of the barrier spring 8, the drug delivery tube 3 will not come into contact with the detonating bomb 5, thereby avoiding friction damage to the detonating bomb 5 during the movement of the drug delivery tube 3. During the pushing and retracting process of the drug delivery tube 3, the barrier spring 8 ensures the safety of the loading process.

[0034] The embodiment of the present invention provides an automatic loading system and working method for explosive bombs. Through the elastic device in the magazine 4, the explosive bomb 5 can be automatically pushed into the guide tube 2. The tube feeder 1 drives the drug delivery tube 3 to be pushed along the guide tube 2 and contact the tail of the explosive bomb 5, so that the drug delivery tube 3 and the explosive bomb 5 move along the guide tube 2 together and are finally sent to the predetermined position of the blast hole for loading, completing the automatic loading and transportation of the explosive bomb 5, thereby realizing full-automatic loading of the explosive bomb 5 and the explosive, without the need for manual loading by on-site workers. The isolation effect of the blocking spring 8 prevents the drug delivery tube 3 from contacting the explosive bomb 5, avoiding friction damage to the explosive bomb 5 by the drug delivery tube 3 during movement, reducing the number of on-site workers for underground mines and tunnel excavation charging, reducing the labor intensity of workers and improving work efficiency, and further ensuring the safety of personnel and loading.

[0035] In one embodiment, if Figure 7 and Figure 8 As shown, a first strip hole 6 is provided along the pushing direction of the drug delivery tube 3 from the first opening 21 of the guide tube 2, for leading out the detonator leg wire 51 of the detonating bomb 5 located in the guide tube 2. Specifically, the first strip hole 6 in this embodiment passes through the inner and outer sides of the guide tube 2. The first strip hole 6 in this embodiment is arranged along the length direction of the guide tube 2, and the end of the first strip hole 6 is connected to the first opening 21 and extends along the pushing direction of the drug delivery tube 3, so that the detonator leg wire 51 of the detonating bomb 5 can extend through the first strip hole 6 when the detonating bomb 5 is pushed to the far end by the drug delivery tube 3.

[0036] In one embodiment, if Figure 4 As shown, the side wall of the magazine 4 is provided with a second strip hole 7 along the length direction of the magazine 4, which is used to lead out the detonator pin 51 of the explosive bomb 5 located in the magazine 4. Specifically, the second strip hole 7 in this embodiment passes through the inner and outer sides of the magazine 4. The second strip hole 7 in this embodiment is located on the side wall of the magazine 4 and extends downward from the top of the magazine 4, so that the detonator pin 51 of the explosive bomb 5 can extend through the second strip hole 7 when the explosive bomb 5 is pushed out by the elastic device.

[0037] In one embodiment, the first strip hole 6 is connected to the second strip hole 7, that is, the end of the first strip hole 6 is connected to the first opening 21, and when the magazine 4 is inserted into the guide tube 2 from the first opening 21, the end of the second strip hole 7 is also connected to the first opening 21. When the detonator 5 is pushed out from the top of the magazine 4 to the guide tube 2, its detonator leg line 51 can also move from the second strip hole 7 to the first strip hole 6.

[0038] In one embodiment, the elastic device includes a compression spring 9 and a support plate 10, one end of the compression spring 9 abuts against the bottom of the magazine 4, and the other end of the compression spring 9 abuts against the bottom of the support plate 10, and the explosive bomb 5 is placed on the top of the support plate 10. In this embodiment, the compression spring 9 provides elastic force, thereby driving the support plate 10 to move upward and ejecting the explosive bomb 5. The working principle of the magazine 4 and the elastic device of this embodiment is similar to that of a magazine. The explosive bombs 5 are placed one by one in the magazine 4. After the magazine 4 is installed in the guide tube 2, the explosive bomb 5 at the top is ejected into the guide tube 2.

[0039] In one embodiment, the magazine 4 is snap-connected to the guide tube 2 via the first opening 21 .

[0040] The embodiment of the present invention further provides a working method of the automatic loading system of explosive bombs according to the above embodiment, comprising:

[0041] S1, installing the magazine 4 containing the detonating bomb 5 at the first opening 21 of the guide tube 2;

[0042] S2, the detonating bomb 5 is ejected from the magazine 4 into the guide tube 2 through the elastic device;

[0043] S3, the tube delivery device 1 drives the drug delivery tube 3 to move along the guide tube 2. When the tube head of the drug delivery tube 3 contacts the tail of the explosive bomb 5, the tail of the explosive bomb 5 is inserted into the drug delivery tube 3, and the drug delivery tube 3 continues to push the explosive bomb 5 to move into the blast hole;

[0044] S4, after the detonating bomb 5 moves to the predetermined position, the drug delivery tube 3 is loaded with drugs.

[0045] In one embodiment, when the explosive bomb 5 moves in the magazine 4, the detonator leg wire 51 of the explosive bomb 5 is led out from the second strip hole 7; when the explosive bomb 5 moves in the guide tube 2, the detonator leg wire 51 of the explosive bomb 5 is led out from the first strip hole 6. It can be understood that when the explosive bomb 5 moves from the magazine 4 to the guide tube 2, its detonator leg wire 51 will also move from the second strip hole 7 to the first strip hole 6.

[0046] In one of the embodiments, in S4, it is determined by a distance sensor whether the detonating bomb 5 has moved to a predetermined position.

[0047] By using the automatic loading system for explosive bombs of the embodiment of the present invention, a series of actions are coordinated to automatically complete the loading, transportation, positioning and charging processes of the explosive bomb 5. The entire process does not require manual operation, which reduces the number of on-site workers, reduces safety hazards, and improves work efficiency.
