In addition, it should be understood that after reading the contents of the present invention, those skilled in the art can make various changes or modifications to the present invention, and these equivalent forms also fall within the scope defined by the claims attached to the application.

[0020] See also Figure 1 , Figure 2 , Figure 3 and Figure 4 It is a schematic diagram of the structure of the present patent, a steel pipe shot blasting and rust removal device, including a steel pipe shot blasting machine 1 and a discharge hopper 2, the steel pipe shot blasting machine 1 is electrically connected to an external power supply, the side walls of the feed port and the discharge port of the steel pipe shot blasting machine 1 are both equipped with a conveying mechanism 3, and the side wall of the conveying mechanism 3 located on the discharge port side of the steel pipe shot blasting machine 1 is rotatably equipped with a discharge hopper 2;

[0021] The conveying mechanism 3 located at one side of the feeding end of the steel pipe shot blasting machine 1 can rotate the steel pipe into the steel pipe shot blasting machine 1, and then the steel pipe is derusted by the steel pipe shot blasting machine 1, and then the steel pipe is conveyed to the discharge hopper 2 for storage through the conveying mechanism 3 on the other side;

[0022] The discharge hopper 2 includes a hopper body 21, a fixed plate 22, a connecting shaft 23 and a blocking net 24. The side wall of the hopper body 21 is installed with a fixed plate 22, and the side wall of the fixed plate 22 is installed with a connecting shaft 23. The side wall of the conveying mechanism 3 is installed with a fixing ring 4, and the connecting shaft 23 is inserted into the fixing ring 4. The connecting shaft 23 can rotate on the fixing ring 4. The inner wall of the hopper body 21 is installed with a blocking net 24.

[0023] When a certain amount of steel pipes are stored in the discharge hopper 2, the hopper body 21 can be lifted upward to tilt the steel pipes, thereby pouring out the steel balls inside the steel pipes for recycling;

[0024] The retaining net 24 can block the steel pipe to prevent it from falling out of the hopper body 21, while the steel shot will leak out from the gaps of the retaining net 24 and enter the collecting tank 8 below.

[0025] The conveying mechanism 3 includes a carrier frame 31, a rotating shaft 32, a sleeve 33 and a tapered groove 34. The carrier frame 31 is installed on the side wall of the steel pipe shot blasting machine 1. The rotating shaft 32 is inserted into the side wall of the carrier frame 31. The rotating shaft 32 is tilted and connected to an external motor. The sleeve 33 is installed outside the rotating shaft 32. The side wall of the sleeve 33 is provided with a tapered groove 34.

[0034] The through groove 10 is arranged below the side wall of the collecting tank 8 so that the steel shot below the screen 9 can be poured out conveniently.

[0035] When the patent is working, the steel pipe is placed in the conical groove 34 on the sleeve 33 in the conveying mechanism 3, and then the conveying mechanism 3 is started, and the external motor drives the rotating shaft 32 to rotate, so that the steel pipe is rotated and sent into the steel pipe shot blasting machine 1, and then the steel pipe is rusted by the steel pipe shot blasting machine 1, and then the steel pipe is transported to the discharge hopper 2 for storage through the conveying mechanism 3 on the other side;

[0036] When a certain number of steel pipes are stored in the discharge hopper 2, the hopper body 21 can be lifted upward by starting the electric hydraulic push rod 5 to tilt the steel pipe, thereby pouring out the steel shots inside the steel pipe. The steel shots will leak out from the gaps in the baffle 24 and enter the collection tank 8 below for recycling.
