Description

Technical Field

[0001] The utility model belongs to the technical field of mine exploitation, and more specifically, particularly relates to a medicine adding device for mine blasting. Background Technique

[0002] When blasting in mine exploitation, in order to safely and efficiently load explosives into blast holes, a special medicine adding device is needed. The pneumatic charger uses wind as the power source and conveys explosives into the blast holes through wind force. It is widely used for charging medium-deep holes in large underground chambers such as coal mines and metal mines. The existing pneumatic chargers generally consist of main tanks, medicine inlets, air sources and power transmission systems, pressure relief ports and other components.

[0003] The existing application number: CN201520309981.8, the utility model relates to a pneumatic charger, which is composed of a stainless steel cylinder body. There are air inlets, medicine conveying ports, pressure relief ports, medicine conveying switches, pressure regulating valves and stirring valves on the tank body. Due to the use of wind force (compressed air) for conveying, the charging speed is fast, the filling density is large, the working efficiency is high, the blasting power is large, the labor cost is saved, the blasting quality is improved, the labor force is greatly reduced, and it is convenient to carry. It is an ideal blasting device for underground mines.

[0004] Based on the above, since the wind tunnel type charger often operates underground, bagged explosives are usually used for filling. The bagged explosives in the lower layer often become caked due to the gravity extrusion of the upper bagged explosives during transportation and other factors. These caked explosives may not be discovered in time due to negligence during the process of manually putting them into the main tank through the medicine inlet, and thus have an adverse impact during the subsequent filling from the main tank into the blast holes. Content of the Utility Model

[0005] In order to solve the above technical problems, the utility model provides a medicine adding device for mine blasting to solve the problem that since the existing wind tunnel type charger often operates underground, bagged explosives are usually used for filling. The bagged explosives in the lower layer often become caked due to the gravity extrusion of the upper bagged explosives during transportation and other factors. These caked explosives may not be discovered in time due to negligence during the process of manually putting them into the main tank through the medicine inlet, and thus have an adverse impact during the subsequent filling from the main tank into the blast holes.

[0019] The first transmission shaft, and the first transmission shaft is rotatably connected to the inside of the fixed box;

[0020] The driving worm gear, and the driving worm gear is coaxially and fixedly connected to the left end of the first transmission shaft, and the driving worm gear meshes with the driving worm.

[0021] Furthermore, the blocking component further includes:

[0022] The driving disc, and the driving disc is coaxially and fixedly connected to the right end of the first transmission shaft;

[0023] The driving column, and the driving column is fixedly connected to the right side of the driving disc.

[0024] Furthermore, the blocking component further includes:

[0025] The connecting piece, and the connecting piece is fixedly connected to the left side of the sieve plate;

[0026] The transmission plate, and the transmission plate is fixedly connected to the lower left end of the connecting piece;

[0027] The compensation strips, and there are two compensation strips. The two compensation strips are respectively fixedly connected to the upper and lower surfaces of the left end of the sieve plate, and the two compensation strips are in contact with the inner wall of the dispersing bin.

[0028] Furthermore, the dispersing component includes:

[0035] Compared with the prior art, the utility model has the following beneficial effects:

[0036] First of all, after the explosive is put into the dispersion bin from the bag through the medicine inlet and falls on the sieve plate, the block-shaped explosive will be blocked on the sieve plate, while the powdery explosive will continue to fall. At the same time, the driving motor drives the sieve plate to move up and down through the blocking assembly. This movement not only accelerates the falling of the powdery explosive on the sieve plate, but also effectively shakes the block-shaped explosive apart, providing guarantee for the smooth progress of the subsequent process.

[0037] Secondly, when the transmission worm rotates, it will also drive the rotating member to rotate through the dispersion assembly, effectively promoting the further refinement of the explosive into powder after it is sieved by the sieve plate, ensuring that the explosive enters the main body of the pneumatic charging device evenly and efficiently, and creating superior conditions for the subsequent safe and reliable detonation.

[0038] In the utility model, after the explosive is put into the dispersion bin from the bag through the medicine inlet, the sieve plate cleverly intercepts the block-shaped explosive, allowing the powdery explosive to fall smoothly. The driving motor drives the sieve plate to vibrate, which not only accelerates the falling of the powdery explosive, but also effectively breaks the block-shaped explosive, laying a solid foundation for the subsequent treatment. At the same time, the transmission worm drives the rotating member through the dispersion assembly to further crush the explosive into powder, ensuring its uniform and efficient entry into the pneumatic charging device, and creating good conditions for the safe and reliable detonation of the explosive.

[0055] A sieve plate 10, and the sieve plate 10 is slidably connected to the inside of the dispersing bin 2;

[0056] A rotating member 13, and the rotating member 13 is rotatably connected to the right end of the connecting box 6;

[0057] The blocking component is arranged inside the fixed box 4 and the dispersing bin 2.

[0058] Among them, the blocking component includes:

[0059] The driving worm 7 is coaxially and fixedly connected to the end of the rotating shaft of the driving motor 5;

[0060] The first transmission shaft 8 is rotatably connected inside the fixed box 4;

[0061] The driving worm gear 801 is coaxially and fixedly connected to the left end of the first transmission shaft 8. The driving worm gear 801 meshes with the driving worm 7.

[0062] Among them, the blocking component further includes:

[0063] The driving disk 9 is coaxially and fixedly connected to the right end of the first transmission shaft 8;

[0064] The driving column 901 is fixedly connected to the right side of the driving disk 9. The function is that the first transmission shaft 8 drives the driving disk 9 to rotate, thereby driving the driving column 901 to make a circular motion around the first transmission shaft 8.

[0065] Among them, the blocking component further includes:

[0066] The connecting piece 1001 is fixedly connected to the left side of the sieve plate 10;

[0067] The transmission plate 1002 is fixedly connected to the lower left end of the connecting piece 1001;

[0068] There are two compensation strips 1003. The two compensation strips 1003 are respectively fixedly connected to the upper and lower surfaces of the left end of the sieve plate 10. The two compensation strips 1003 are in contact with the inner wall of the dispersing bin 2. The function is that the circular motion of the driving column 901 drives the transmission plate 1002 and the connecting piece 1001 to move up and down through the straight slot in the transmission plate 1002, thereby driving the sieve plate 10 to move up and down, enabling the explosives on the sieve plate 10 to fall quickly.

This can not only make the powdered explosive on the sieve plate 10 fall quickly, but also toss the lumpy explosive up and down to break up the lumpy explosive. The two compensation strips 1003 can block the slot on the left side of the dispersion bin 2 that provides the up and down movement of the connecting piece 1001, ensuring the sealing performance of the dispersion bin 2 and ensuring the smooth progress of the subsequent process.
