DETAILED DESCRIPTION

[0022] The technical scheme in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the described embodiment is only a part of the embodiment of the utility model, rather than all the embodiments. The components of the embodiment of the utility model generally described and shown in the drawings here can be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiment of the utility model provided in the drawings is not intended to limit the scope of the utility model claimed for protection, but merely represents the selected embodiment of the utility model. Based on the embodiment of the utility model, all other embodiments obtained by those skilled in the art without making creative work belong to the scope of protection of the utility model.

[0023] like Figure 1-4As shown, this embodiment proposes a feeding mechanism of a shot blasting machine, including a feeding box 1, a feeding cover 2 arranged on the top of the feeding box 1, and the surfaces of the feeding box 1 and the feeding cover 2 are also provided with: a lower connecting ring 4, an upper connecting ring 3, a first fixing ring 5, a second fixing ring 6 and a fixing threaded rod 7, the lower connecting ring 4 and the upper connecting ring 3 are respectively formed at the edges of the feeding box 1 and the feeding cover 2, the first fixing ring 5 and the second fixing ring 6 are arranged on the surfaces of the lower connecting ring 4 and the upper connecting ring 3, and the fixing threaded rod 7 is arranged at one end of the first fixing ring 5 and the second fixing ring 6, the feeding cover 2 is placed on the top of the feeding box 1, and the upper connecting ring 3 is aligned with the lower connecting ring 4, and then the first fixing ring 5 and the second fixing ring 6 are wrapped. Wrap it around the surface of the upper connecting ring 3 and the lower connecting ring 4, so that the inner walls of the first fixing ring 5 and the second fixing ring 6 fit with the surfaces of the upper connecting ring 3 and the lower connecting ring 4, and then screw the fixing threaded rod 7 into one end of the first fixing ring 5 and the second fixing ring 6, and fix the first fixing ring 5 and the second fixing ring 6 together through the fixing threaded rod 7, so that the first fixing ring 5 and the second fixing ring 6 can fix the discharge box 1 and the discharge cover 2. When it is necessary to repair the internal structure of the discharge box 1, it is only necessary to loosen the fixing threaded rod 7, and then remove the first fixing ring 5 and the second fixing ring 6. In this way, the installation and disassembly of the discharge structure can be completed quickly, thereby facilitating the repair of the internal structure of the discharge structure.

[0024] Several groups of limiting columns 8 are arranged at the bottom of the upper connecting ring 3, and one end of the limiting columns 8 is rounded, and several groups of limiting grooves 9 are opened on the top of the lower connecting ring 4. At the same time, the positions of the several groups of limiting columns 8 correspond to the positions of the limiting grooves 9. When the discharge cover 2 is placed on the top of the discharge box 1, each group of limiting columns 8 is inserted into the corresponding limiting grooves 9, which can limit the position of the upper connecting ring 3 and the lower connecting ring 4, so that the discharge box 1 and the discharge cover 2 are aligned with each other, thereby facilitating the fixation of the discharge box 1 and the discharge cover 2 by the first fixing ring 5 and the second fixing ring 6. The ends of the limiting columns 8 are rounded, which can better enable the limiting columns 8 to be inserted into the limiting grooves 9.

[0025] The first fixing ring 5 and the second fixing ring 6 are rotatably connected via a rotating shaft, and the inner walls of the first fixing ring 5 and the second fixing ring 6 are both provided with a rubber layer 10. The first fixing ring 5 and the second fixing ring 6 can be limited at one end by the rotating shaft connection, so as to facilitate the fixation of the other end of the first fixing ring 5 and the second fixing ring 6. The rubber layer 10 can reduce the gap between the first fixing ring 5, the second fixing ring 6 and the upper connecting ring 3, the lower connecting ring 4 through its own deformability, thereby ensuring the sealing between the discharge box 1 and the discharge cover 2. At the same time, the rubber layer 10 can also increase the friction between the first fixing ring 5, the second fixing ring 6 and the upper connecting ring 3, the lower connecting ring 4, so that the first fixing ring 5 and the second fixing ring 6 are more stable.

[0026] The end of the fixed threaded rod 7 is provided with a handle, and the handle is set to be flat, and a fixing ring 11 is set at one end of the fixed threaded rod 7 close to the handle, and a limiting ring 12 is set on the other end of the fixed threaded rod 7, and the limiting ring 12 is set to be hexagonal. The flat shape of the end of the fixed threaded rod 7 can better enable the staff to rotate the fixed threaded rod 7 by hand. When the fixed threaded rod 7 is screwed into one end of the first fixing ring 5 and the second fixing ring 6, the fixing ring 11 can limit the first fixing ring 5 and the second fixing ring 6 to prevent the first fixing ring 5 and the second fixing ring 6 from being screwed out from the end of the fixed threaded rod 7. After the fixed threaded rod 7 is screwed in, the limiting ring 12 is threadedly installed on the surface of the fixed threaded rod 7 until one side of the limiting ring 12 is in contact with the surface of the second fixing ring 6. Through the cooperation of the limiting ring 12 and the fixing ring 11, the first fixing ring 5 and the second fixing ring 6 are further limited, making the structure more stable.

[0027] Two groups of feed pipes 13 are symmetrically arranged on the top of the material discharge cover 2, and the openings of the two groups of feed pipes 13 are both arranged in a trumpet shape, so that the size of the opening of the material discharge structure can be increased, so that the material can better enter the material discharge structure.

[0028] Several groups of support rods 14 are arranged at the bottom edge of the material box 1, and the several groups of support rods 14 are evenly distributed at equal intervals. A pipe 15 is connected to the center position of the bottom of the material box 1, and the other end of the pipe 15 is connected to the shot blasting machine. Through the cooperation of several groups of support rods 14, the material box 1 can be supported, thereby making the material box 1 more stable.
