[0019] The technical scheme in the utility model will be further described below in combination with the drawings and embodiments.

[0020] In the description of the utility model, it is understood that the orientation or positional relationship indicated by the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential" and the like is based on the orientation or positional relationship shown in the drawings, and is only for the convenience of describing the utility model and simplifying the description, and therefore cannot be understood as a limitation on the utility model.

[0021] In the exemplary embodiment, as shown in Figure 1 The embodiment provides a steel ball recycling device, which comprises a shell 1, a feeding port is arranged at the upper end of the shell 1, and a discharging port is arranged at the lower end of the shell 1, a supporting ring 2 and a sieve cylinder 3 covering the supporting ring 2 are fixedly connected in the shell 1, a vibrating motor 4 and a filter plate 5 located below the vibrating motor 4 are installed in the sieve cylinder 3, a plurality of filter holes are arranged on the filter plate 5, a blocking plate 6 covering the sieve cylinder 3 is detachably connected in the shell 1, a plurality of blocking holes 7 are arranged on the blocking plate 6, the diameter of the blocking holes 7 is greater than that of the filter holes, the blocking holes 7 are used for intercepting large-size sundries, the filter holes on the filter plate 5 are small, and the steel balls are allowed to pass through, when the vibrating motor 4 operates, the steel balls can pass through more quickly, and therefore the effect of rapid screening is achieved, a first connecting pipe 8 and a second connecting pipe 9 are further connected to the shell 1, and both of them are further connected to a third connecting pipe 10, the third connecting pipe 10 is further connected to an air extractor, the first connecting pipe 8 is in communication with the upper portion of the sieve cylinder 3, the second connecting pipe 9 is in communication with the lower portion of the sieve cylinder 3, and the operation of the air extractor generates negative pressure in the first connecting pipe 8 and the second connecting pipe 9, and dust in the shell 1 is extracted.

[0022] In the above embodiment, the sieve cylinder 3 arranged in the shell 1 can screen the steel balls, the first connecting pipe 8 and the second connecting pipe 9 above and below the sieve cylinder 3 can extract dust upward and downward under the assistance of the air extractor, dust is removed, the overall cleaning time is shortened, and the problem that the steel balls need to be screened and dusted in steps in the prior art is solved.

[0023] As shown in Figure 1As shown, the upper end of the casing 1 is also fixedly connected with a feeding hopper 11, and the intercepting plate 6 is fixedly connected with a resisting ring 12 which can abut against the inner wall of the feeding hopper 11. The upper end of the feeding hopper 11 is larger than the lower end, and the lower end is connected with the inner wall of the casing 1. The resisting ring 12 is also large at the upper end and small at the lower end. In this way, the resisting ring 12 can be kept stable and not displaced downward when abutting against the feeding hopper 11, and it can also be lifted upward to facilitate the cleaning of the casing 1 after the work is completed.

[0024] Further, as shown in Figure 1 、 2 The lower plate surface of the intercepting plate 6 is also fixedly connected with a protective cover 13 which covers the vibration motor 4, and all the intercepting holes 7 are located outside the protective cover 13. A through hole is provided on the intercepting plate 6 and located inside the protective cover 13. The through hole is used for the power line 14 of the vibration motor 4 to pass through, thereby facilitating wiring. The gap after the power line 14 passes through the through hole is smaller, and it will not allow the shot steel balls or other impurities to enter.

[0025] In a further aspect, an extension cylinder 15 which surrounds the through hole can be fixedly connected to the intercepting plate 6. The power line 14 passes through the extension cylinder 15, thereby providing better protection and allowing the operator to hold it, which facilitates the installation and disassembly of the intercepting plate 6. Further, the lower plate surface of the intercepting plate 6 is also fixedly connected with a protective cover 13 which covers the vibration motor 4, and all the intercepting holes 7 are located outside the protective cover 13. The protective cover 13 provides protection for the vibration motor 4 from below, preventing the shot steel balls from falling onto the vibration motor 4. More specifically, a support plate 17 is provided in the sieve cylinder 3, and the vibration motor 4 is installed on the support plate 17. A plurality of connecting rods 18 are fixedly connected between the support plate 17 and the sieve cylinder 3. The connecting rods 18 have gaps therebetween, which do not block the shot steel balls from passing through. The support plate 17 is used for directly installing the vibration motor 4. A protective cylinder 19 which surrounds the vibration motor 4 is also fixedly connected to the support plate 17, and the upper end of the protective cylinder 19 extends into the protective cover 13. In this way, the vibration motor 4 is more protected.

[0026] As shown in Figure 1 、 3 The lower end of the sieve cylinder 3 is also fixedly connected with a reduced-diameter cylinder 16 which can pass through the support ring 2 downward. The reduced-diameter cylinder 16 is located inside the support ring 2. In this way, when the vibration motor 4 operates, the sieve cylinder 3 is limited by the reduced-diameter cylinder 16, preventing it from colliding excessively with the inner wall of the casing 1 (the distance between the outer wall of the reduced-diameter cylinder 16 and the inner wall of the support ring 2 is smaller than the distance between the outer wall of the sieve cylinder 3 and the inner wall of the casing 1). Further, all the intercepting holes 7 have a direct projection inside the sieve cylinder 3. In this way, the shot steel balls falling downward can fall directly into the sieve cylinder 3.

[0027] Finally, it is explained that the above embodiments are only used to illustrate the technical solutions of the present application and are not limited. Although the present application has been described in detail with reference to the preferred embodiments, it should be understood by those skilled in the art that the technical solutions of the present application can be modified or replaced by equivalents without departing from the purpose and scope of the present application. The technical solutions of the present application should be covered in the scope of the claims of the present application.
