[0018] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present invention.

[0019] The present invention provides a discharge structure as Figures 1-3 shown;

[0020] Embodiment: The discharge structure includes a channel installation substrate 1, an outer cylinder 2 of a metal discharge channel, an external gas supply pipeline 6, and a vibration inner cylinder channel 10. A neck type connection transition part 11 is provided at the top of the outer cylinder 2 of the metal discharge channel. The outer cylinder 2 of the metal discharge channel is welded to the circular hole channel of the channel installation substrate 1 through the neck type connection transition part 11. One end of the external gas supply pipeline 6 is provided with a sealing plug 7, and the other end of the external gas supply pipeline 6 is provided with an external threaded connection column 8. An inflation joint 9 is provided in the middle of one side of the outer cylinder 2 of the metal discharge channel. The inflation joint 9 is plugged and connected with the sealing plug 7. The vibration inner cylinder channel 10 is arranged inside the outer cylinder 2 of the metal discharge channel through a vibration mechanism;

[0021] The vibration mechanism includes two reset sleeves 13 and two knocking connecting rods 14. One ends of the two knocking connecting rods 14 are arranged at the spring seats inside the corresponding reset sleeves 13. The knocking parts of the two knocking connecting rods 14 are connected to the vibration inner cylinder channel 10 and are symmetrically distributed in a ring shape. The two reset sleeves 13 are communicated with the inflation joint 9 through pipelines.

[0022] In this implementation scheme, as Figure 3 shown, in order to screen and filter the materials to be discharged, so that the materials meeting the discharging conditions can fall for discharging operations, a magnetic installation ring 15 connected to the inner wall of the vibration inner cylinder channel 10 is arranged inside the neck type connection transition part 11. A positioning clamping column 16 is arranged on the side of the top end of the magnetic installation ring 15. The positioning clamping column 16 is plugged into the neck type connection transition part 11. A filter mesh cover 17 connected to the inner cavity of the vibration inner cylinder channel 10 is arranged at the bottom of the magnetic installation ring 15.

[0023] In this embodiment, as Figure 2 shown, in order to improve the sealing effect of the vibrating inner cylinder channel 10 installed inside the outer cylinder 2 of the metal discharge channel, a sealing connection sleeve 12 is provided at the top of the vibrating inner cylinder channel 10, and the sealing connection sleeve 12 is connected to the neck-type connection transition part 11.

[0024] In this embodiment, in order to better connect to the discharge hole position of the ball mill cylinder and improve the firmness of its own connection, a front guide connection part 3 is provided at the top of the circular hole of the channel installation substrate 1, and an extrusion-type sealing outer ring 4 is provided at the outer circle of the front guide connection part 3; threaded counterbores 5 are provided at the four corners of the channel installation substrate 1.

[0025] A ball mill is applied to a discharge structure. Among them, the thickness of the ball mill cylinder is equal to the height of the front guide connection part 3 and the extrusion-type sealing outer ring 4.

[0026] The working principle of the present utility model: The channel installation substrate 1 is installed at the discharge hole position of the ball mill cylinder through the threaded counterbores 5. The front guide connection part 3 corresponds to the aperture of the discharge hole position through the extrusion-type sealing outer ring 4, and it is necessary to ensure that the thickness of the ball mill cylinder is equal to the height of the front guide connection part 3 and the extrusion-type sealing outer ring 4 during the design stage, so as to avoid gaps caused by protruding structures and ensure full feeding. During the feeding process, the sealing plugs 7 and external threaded connection columns 8 at both ends of the external air supply pipeline 6 are respectively connected to the inflation joint 9 of the outer cylinder 2 of the metal discharge channel and the high-pressure air source. The high-pressure air source performs intermittent deflation operations under the control of the program, so that the gas enters the inside of the reset sleeve 13 through the pipeline and enables the knocking connecting rod 14 to reciprocate telescopically, and then can knock the vibrating inner cylinder channel 10 and present a certain regular knocking motion to perform a knocking operation on the vibrating inner cylinder channel 10, thereby enabling the vibrating inner cylinder channel 10 to vibrate and avoiding the blockage of the feeding material; and adopting the pneumatic control method helps to reduce noise and is convenient for quick start-up.

[0027] In this technical solution, the number of the reset sleeves 13 and the knocking connecting rods 14 is equal, and according to the outer diameter size of the actual vibrating inner cylinder channel 10, the corresponding number of reset sleeves 13 and knocking connecting rods 14 is appropriately designed, and the reset sleeves 13 and the knocking connecting rods 14 need to be annularly distributed at equal arcs.
