[0022] Please refer to Figs. 1 to 3 A special waste lead bucket for radioactive objects, comprising a special lead bucket body for radioactive objects 1, the lead bucket body 1 is composed of a bucket body 101, a bucket cover 102 and a sealing cover 104, the bucket cover 102 is internally provided with a feeding hole 103 communicating with the bucket body 101, the sealing cover 104 is tightly embedded in the feeding hole 103, a step is arranged in the feeding hole 103, and a sealing gasket is sleeved and mounted on the outer surface of the sealing cover 104, and the sealing cover 104 is tightly combined with the feeding hole 103 through the sealing gasket. The bucket body 101 is internally hollow, and the bucket cover 102 is bolted to the top end of the bucket body 101.

[0023] In the embodiment, the bucket body 101 is externally provided with a cover opening structure 2 for moving the sealing cover 104 and a treading structure 3 used in cooperation with the cover opening structure 2; the cover opening structure 2 comprises a guide sleeve 201, a lifting rod 202, a swing arm 203, a connecting shaft 204, a pulley 205, a mounting table 207 and a reset spring 208, the guide sleeve 201 is internally provided with a guide sliding groove 206 matched with the pulley 205; the treading structure 3 comprises a pedal 301, a connecting frame 302 and a connecting rod 303, the two ends of the connecting rod 303 are respectively connected with the pedal 301 and the mounting table 207. The reset spring 208 is fixedly installed between the mounting table 207 and the guide sleeve 201, the reset spring 208 surrounds the outside of the lifting rod 202, the pulley 205 is bearing-mounted on the outer surface of the lifting rod 202, and the pulley 205 is rollingly connected with the inner wall of the guide sliding groove 206.

[0024] Specifically, the guide sleeve 201 is internally hollow, and perforations are formed in the upper and lower ends of the guide sleeve 201 and extend to the outside. A connecting plate is welded to the outer surface of the guide sleeve 201 and is fixed to the outer surface of the barrel body 101. The two ends of the lifting rod 202 extend through the perforations in the guide sleeve 201. The two ends of the lifting rod 202 are connected to the swing arm 203 and the mounting table 207, respectively.

[0025] The two ends of the connecting shaft 204 are connected to the sealing cover 104 and the other end of the swing arm 203, respectively. The top end of the lifting rod 202 is fixedly connected to the lower surface of the swing arm 203, and the bottom end of the lifting rod 202 is rotatably connected to the upper surface of the mounting table 207. The lifting rod 202 is composed of two rod bodies, and the two rod bodies are threadedly connected, which can better adjust the sealing cover 104 to make it tightly connected to the feeding hole 103.

[0026] In this embodiment, a groove is formed in the side of the pedal 301 close to the barrel body 101. The bottom end of the connecting rod 303 is hingedly connected to the groove, and the top end of the connecting rod 303 is fixedly connected to the lower surface of the mounting table 207. The number of the connecting frames 302 is two, and the two connecting frames 302 are symmetrically arranged.

The installation of the reset spring 208 enables the sealing cover 104 to be tightly connected to the feeding hole 103, thereby improving the sealing of the lead barrel body 1.

[0028] The working principle of the above-mentioned embodiment is as follows:

[0029] When used, the worker steps on the pedal 301, one end of the pedal 301 is raised, and the mounting table 207 is lifted by the connecting rod 303. The mounting table 207 moves upward and drives the lifting rod 202 to move upward. Since the bottom end of the lifting rod 202 is rotatably arranged, the lifting rod 202 rotates when it moves upward through the rolling connection of the pulley 205 and the guide sliding groove 206, so that the swing arm 203 drives the sealing cover 104 to move upward and rotate, thereby facilitating the opening of the feeding hole 103 by the worker.
