[0019] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only 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 making creative efforts are within the scope of protection of the present invention.

[0020] The utility model provides a mid-conical sealing structure of a trolley, comprising a sealing cone surface 1, a first connecting member 7 and a second connecting member 8. The cross-sectional area of ​​the first connecting member 7 is L-shaped, the horizontal end of the first connecting member 7 is fixedly connected to the outer ring at the top of the sealing cone surface 1, the vertical end of the first connecting member 7 is located outside the sealing cone surface 1, and the vertical end of the first connecting member 7 is movably connected to the second connecting member 8.

[0021] The second connecting member 8 is an annular structure. The bottom of the second connecting member 8 is connected to the trolley's slewing support turntable structure, and the top of the second connecting member 8 is fixedly connected to the bottom of the trolley's workpiece carrying platform. With this arrangement, the slewing support turntable structure can support the workpiece carrying platform through the second connecting member 8 and drive the workpiece carrying platform to rotate, facilitating the use of the trolley. The inner side of the top of the second connecting member 8 is movably connected to the first connecting member 7.

[0022] From the above description, it can be seen that the rotary support turntable structure of the trolley is blocked by the structure composed of the sealing cone surface 1, the first connecting member 7 and the second connecting member 8. The shot blasting falling from the workpiece carrying platform cannot affect the rotary support turntable structure, which facilitates the use of the rotary support turntable structure.

[0023] A discharge pipe 2 is fixedly connected to the middle of the bottom of the sealing cone 1. The other end of the discharge pipe 2 passes through the trolley body and extends to the bottom of the trolley body. Through the setting of the discharge pipe 2, the shot blasting falling into the sealing cone 1 can be discharged from the discharge pipe 2. The size of the sealing cone 1 gradually decreases from top to bottom, so that the shot blasting falling into the sealing cone 1 can be gathered and discharged from the discharge pipe 2.

[0024] An inner conical surface 3 is fixedly connected to the inner cavity of the sealing cone 1. One side of the bottom of the inner conical surface 3 is fixedly connected to the inner wall of the sealing cone 1. A gap is formed between the rest of the bottom of the inner conical surface 3 and the sealing cone 1 for the shot blasting to pass through. The size of the inner conical surface 3 gradually increases from top to bottom, and the size of the inner conical surface 3 at the end closest to the discharge pipe 2 is larger than that at the other end. The configuration of the inner conical surface 3 can reduce the impact of shot blasting on the sealing cone 1, extend the service life of the sealing cone 1, and facilitate the movement of shot blasting within the sealing cone 1.

[0025] To sum up: when the middle conical sealing structure of the trolley is in use, the structure formed by the sealing cone surface 1, the first connecting member 7 and the second connecting member 8 can block the trolley body 4 and the rotary support turntable structure 5 of the trolley, preventing the shot blasting from falling on the trolley body 4 and the rotary support turntable structure 5, and preventing the shot blasting from getting stuck in the rotary support turntable structure 5, which is convenient for the use of the trolley, and the workpiece carrying platform 6 is located above the trolley body 4. Holes for the shot blasting to fall are evenly provided on the part of the workpiece carrying platform 6 for the shot blasting to fall. The shot blasting falls into the sealing cone surface 1 through the holes, and is discharged through the discharge pipe 2 under the action of gravity, which is convenient for the recycling and reuse of the shot blasting.

[0026] The standard parts used in the present invention can all be purchased from the market, and special-shaped parts can be customized according to the description in the specification and the drawings. The specific connection methods of each part adopt conventional means such as mature bolts, rivets, welding, etc. in the existing technology. The machinery, parts and equipment all adopt conventional models in the existing technology and will not be described in detail here. The content not described in detail in this specification belongs to the existing technology known to professional and technical personnel in this field.
