DETAILED DESCRIPTION

[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] The rotary shot blasting machine offers two technical solutions:

[0026] like Figure 1 , 2 Figure 5 shows a first embodiment: it includes a protective box 1 and a workpiece rotating mechanism 2 for driving the workpiece to rotate. A discharge mechanism is provided inside the protective box 1. The discharge mechanism includes:

[0027] Multiple anti-smashing components 3 are arranged at the bottom of the protective box 1. The anti-smashing components 3 include multiple bottom plates 31, and the multiple bottom plates 31 are arranged at an angle. The left sides of the multiple bottom plates 31 are fixedly connected with anti-smashing plates 32 by bolts 34, and the left sides of the multiple anti-smashing plates 32 are evenly spaced.

[0028] When the steel ball falls under the protective box 1, it is received by the anti-smashing component 3. The anti-smashing component 3 is tilted to facilitate the steel ball to slide to the bottom for discharge, thus avoiding the problem of steel ball and metal debris residue.

[0029] like Figure 1-4The second embodiment is shown, and the main difference from the first embodiment is that: a swing component 4 is arranged outside the protective box 1 and is used to drive multiple anti-smashing components 3 to swing, the swing component 4 includes multiple rotating rods 41, and the multiple rotating rods 41 are equidistantly connected to the front of the inner wall of the protective box 1 for rotation, and the multiple rotating rods 41 penetrate to the rear of the protective box 1, and the multiple anti-smashing components 3 are respectively fixedly connected to the surfaces of the rotating rods 41 at corresponding positions, and the ends of the multiple rotating rods 41 located at the rear of the protective box 1 are fixedly connected with a swing rod 42, a slide rail 43 is fixedly connected to the left side of the back of the protective box 1, and a pushing frame 44 is slidably connected to the inner surface of the slide rail 43, and the pushing frame 44 is used to push the swing rod 42 to swing, and a push plate 45 is fixedly connected to the right side of the pushing frame 44, and a driving motor 46 is fixedly connected to the right side of the back of the protective box 1 through a support plate, and a cam 47 is fixedly connected to the output end of the driving motor 46, and the cam 47 is located on the right side of the push plate 45, and a return spring 48 is fixedly connected between the left side of the inner wall of the slide rail 43 and the left side of the pushing frame 44.

[0030] The pushing frame 44 is composed of a plurality of pushing blocks 441 , and a middle rod 443 is fixedly connected between adjacent pushing blocks 441 . Through slots 442 are formed inside the plurality of pushing blocks 441 .

[0031] A U-shaped opening 421 is provided at the top of the swing rod 42, and a fixing rod 422 is fixedly connected between the front and back sides of the inner wall of the U-shaped opening 421. The positions of the plurality of push blocks 441 correspond to the positions of the plurality of swing rods 42, and the fixing rod 422 is located inside the through slot 442 at the corresponding position.

[0032] After the metal debris falls onto the anti-smashing plate 32, the swing assembly 4 is started intermittently, so that the anti-smashing plate 32 swings back and forth, so that the metal debris on the anti-smashing plate can be completely discharged.

[0033] When in use, the steel balls are sprayed onto the workpiece and then fall down. The steel balls fall onto the anti-smashing plate 32 and slide to the discharge port through the guidance of the guide groove 33. The drive motor 46 is started intermittently during the operation of the equipment. The drive motor 46 starts and drives the cam 47 to rotate. The cam 47 rotates and contacts the push plate 45, thereby pushing the pushing frame 44 to move. The pushing frame 44 moves and the swing arm 42 rotates to one side through the cooperation of the through groove 442 and the fixed rod 422. When the drive motor 46 rotates to the other end, the pushing frame 44 is reset by the action of the reset spring 48, so that the swing arm 42 rotates in the opposite direction, that is, the swing arm 42 swings left and right. The swing arm 42 swings and drives the bottom plate 31 to swing left and right through the driving of the rotating rod 41, so that the metal debris remaining on the anti-smashing plate 32 slides off.

[0034] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.
