Rust removal equipment for stud group of steel-concrete connecting piece

The invention discloses derusting equipment for a stud group of a steel-concrete connecting piece. The technical problems that if a large number of studs are subjected to rust removal one by one, the workload is large, and the construction efficiency is low are solved. On-site shot blasting rust removal is easy to cause random splashing of sprayed materials, the environment is polluted, sprayed steel shots possibly strike workers, the attention of the workers is distracted, and the personal safety of the workers is influenced; rust on the inner side of a stud head is difficult to remove, the rust removal effect is easily influenced, the structural durability is reduced, the service life of a bridge is shortened, and the life and property safety of passing vehicles and personnel is influenced. According to the technical scheme, the steel-concrete connecting piece stud group derusting equipment comprises a shot blasting mixer, a top cover and the like; and an openable top cover is arranged on the upper side of
