[0031] Please refer to Figures 1 to 8 The present invention provides a shot blasting cleaning machine, comprising: a box body 10, a clamping assembly is arranged in the box body 10, the clamping assembly includes two clamping plates, and a clamping gap 13 is provided between the two clamping plates for accommodating at least part of the chain to be cleaned. The size of the clamping gap 13 is adjustable, and the two clamping plates can swing around two mutually perpendicular preset axes to drive the chain to be cleaned to shake.

[0032] The shot blasting machine of the present invention comprises a box body 10, in which a clamping assembly is arranged, and the clamping assembly comprises two clamping plates, at least part of the chain to be cleaned is passed through a clamping gap 13 between the two clamping plates, and the two clamping plates swing around two mutually perpendicular preset axes, so that the two clamping plates drive the chain to be cleaned to shake irregularly, so that the contact position of the chain to be cleaned and the shot blasting particles changes, so that the reverse side of the chain to be cleaned and the inside of the hole of the chain to be cleaned can fully contact with the shot blasting particles, thereby avoiding the shot blasting dead angle that is easy to appear in the mining chain, thereby solving the problem of shot blasting dead angle that is easy to appear in the mining chain in the prior art.

[0033] Specifically, two symmetrically arranged shot blasting wheels 9 are fixedly connected through the upper surface of the box body 10, and the shot blasting outlet of the shot blasting wheel 9 is located above the chain to be cleaned. The shot blasting particles fall from the shot blasting outlet onto the chain to be cleaned to perform shot blasting on the chain to be cleaned; the box body 10 can provide a closed shot blasting environment to avoid dust generated during shot blasting that affects the environment in the workshop.

[0034] In this embodiment, the two clamping plates are respectively a first clamping plate 11 and a second clamping plate 12. The second clamping plate 12 is arranged relative to the first clamping plate 11 and close to the bottom of the box body 10. An arc block 14 is arranged on one side of the second clamping plate 12. The clamping assembly also includes an adjusting protrusion 15. The adjusting protrusion 15 has a first state of contact with the arc block 14 and a second state of separation from the arc block 14. The adjusting protrusion 15 is rotatably arranged around a first preset axis so that the adjusting protrusion 15 can switch between the first state and the second state; wherein, when the adjusting protrusion 15 is in the first state, the adjusting protrusion 15 squeezes the arc block 14 so that the arc block 14 swings around the first preset axis and the second preset axis, and the first preset axis and the second preset axis are perpendicular to each other.

[0035] Specifically, the arc block 14 plays a role of increasing the counterweight. By adjusting the contact and separation between the protrusion 15 and the arc block 14, the swing amplitude and swing direction of the second clamping plate 12 and the first clamping plate 11 can be accurately controlled, thereby driving the chain to be cleaned to shake irregularly.

[0036] Specifically, a lifting handle 110 is fixedly connected to the center of the upper surface of the first clamping plate 11 .

[0037] In specific implementation, the arc block 14 has a first arc surface 141 and a second arc surface 142 that are connected to each other. From the end of the first arc surface 141 away from the second arc surface 142 to the end of the first arc surface 141 close to the second arc surface 142, the distance between the circumferential surface of the arc block 14 and the second clamping plate 12 along the height direction of the box body 10 gradually increases. From the end of the second arc surface 142 away from the first arc surface 141 to the end of the second arc surface 142 close to the first arc surface 141, the distance between the circumferential surface of the arc block 14 and the second clamping plate 12 along the height direction of the box body 10 gradually increases. When the adjusting protrusion 15 switches to the first state, the adjusting protrusion 15 first contacts the first arc surface 141. At this time, the adjusting protrusion 15 will squeeze the arc block 14, so that the arc block 14 rotates around the first preset axis, until the adjusting protrusion 15 rotates to contact the connection between the first arc surface 141 and the second arc surface 142. At this time, the adjusting protrusion 15 will squeeze the arc block 14, so that the arc block 14 rotates around the second preset axis, and then the adjusting protrusion 15 rotates to contact the second arc surface 142. At this time, the adjusting protrusion 15 will squeeze the arc block 14, so that the arc block 14 continues to rotate around the first preset axis, and then the adjusting protrusion 15 rotates to separate from the arc block 14, and then the adjusting protrusion 15 switches to the second state.

[0038] In this embodiment, a connecting column 16 is arranged between the first clamping plate 11 and the second clamping plate 12, and the connecting column 16 extends along the height direction of the box body 10. The first clamping plate 11 can be movably inserted into the connecting column 16 along the extension direction of the connecting column 16 relative to the second clamping plate 12 to adjust the size of the clamping gap 13. A limiting plate 17 is arranged on the side of the connecting column 16 away from the first clamping plate 11 to limit the first clamping plate 11.

[0039] Specifically, the connecting column 16 is used to connect the first clamping plate 11 and the second clamping plate 12, so that the first clamping plate 11 can swing with the second clamping plate 12, and the first clamping plate 11 slides on the connecting column 16 to adjust the size of the clamping gap 13, thereby ensuring that the clamping gap 13 can accommodate chains of different sizes to be cleaned, so that the shot blasting cleaning machine of the present application is suitable for chains of different specifications to be cleaned, thereby expanding the scope of application of the shot blasting cleaning machine of the present application; the limiting plate 17 is used to limit the first clamping plate 11 to prevent the first clamping plate 11 from excessive sliding, thereby maintaining the structural stability of the clamping assembly.

[0041] Specifically, the two ends of the elastic member 18 are respectively connected to the first clamping plate 11 and the second clamping plate 12, so that the elastic force of the elastic member 18 can drive the first clamping plate 11 to move along the height direction of the box body 10 toward the direction close to the second clamping plate 12, ensuring that the first clamping plate 11 and the second clamping plate 12 can tightly clamp the chain to be cleaned, while also further improving the connection reliability between the first clamping plate 11 and the second clamping plate 12, so that the first clamping plate 11 can swing with the second clamping plate 12; the elastic pad 19 is arranged on the inner side of the two clamping plates, and the elastic pad 19 is used to directly contact the chain to be cleaned, thereby reducing the hard contact when the two clamping plates clamp the chain to be cleaned, and further protecting the chain to be cleaned.

[0042] In specific implementation, when installing the chain to be cleaned, the user drives the first clamping plate 11 to move in a direction away from the second clamping plate 12, so that the elastic member 18 is stretched and filled with elastic force. When the chain to be cleaned enters the clamping gap 13, the user stops moving the first clamping plate 11. At this time, the elastic force of the elastic member 18 can drive the first clamping plate 11 to move along the height direction of the box body 10 toward the direction close to the second clamping plate 12.
