Drop hammer subassembly 20 sets up in lifting the hammer subassembly outside, trapped orbit 21 is fixed, do the position of adjusting the ejector pad 23 that links to each other with adjustment track 22 for trapped orbit 21's motion through adjustment track 22, adjustment track 22's regulation can be directly accomplished through the regulation pole 24 with adjustment track 22 fixed connection, the one end of adjusting pole 24 extends to the casing 10 outside, the staff can be according to the actual production demand like this, accomplish the regulation of the hammer power of shaking and rapping through adjusting pole 24 in real time, not only improved drop hammer subassembly 20's regulation convenience greatly, simultaneously can also combine the actual production situation to shake the regulation of the hammer amplitude of oscillation in real time in order to produce different power of shaking, rapping device's practicality has been improved greatly.

As shown in fig. 3 and 4, the locking structure between the fixed rail 21 and the adjustment rail 22 includes a first engaging tooth 31 disposed on the fixed rail 21, a rack 32 disposed in the adjustment rail 22 and floating up and down and having a second engaging tooth, and a cam 33 for controlling the rack 32 to float and engage or disengage the first engaging tooth 31 by rotating, the cam 33 is connected to the adjustment lever 24, and a cavity 34 for accommodating the rack 32 and the wheel 33 is disposed on a mating surface of the adjustment rail 22 and the fixed rail 21.

In the actual operation process of the rapping device, as the push block 23 is a force application member, the fixed rail 21 and the adjustment rail 22 need to be relatively fixed once the position adjustment is completed, thereby ensuring the fixed position of the push block 23. The first engaging teeth 31 and the rack 32 engaged therewith can easily engage and fix the fixed rail 21 and the adjustment rail 22. When the position of the push block 23 needs to be adjusted, the adjusting rod 24 is controlled to rotate the cam 33, the rack 32 loses the limit of the top of the cam and is separated from the first meshing teeth 31, at this time, the adjusting rod 24 can control the adjusting track 22 to slide to a target position along the fixed track 21, then the adjusting rod 24 is controlled to rotate the cam 33, the top of the cam 33 is abutted against the rack 32 to limit, the second meshing teeth of the rack 32 are meshed with the first meshing teeth 31, and the position fixing of the fixed track 21 and the adjusting track 22 can be realized.

In order to further improve the convenience in the adjustment process of the adjustment track 22, as shown in fig. 4, a spring 35 which is in a stretching state and applies a traction force to the rack 32 is further arranged in the cavity 34, one end of the rack 32 is rotatably connected to the inner wall of the cavity 34, the other end of the rack 32 abuts against the cam 33, the spring 35 is arranged in the middle of the rack 32, one end of the spring 35 is fixed to the inner wall of the cavity 34, and the other end of the spring 35 is fixed to the rack 32. Thus, the rack 32 forms a lever, and since the spring 35 is in a stretched state, when the position of the adjusting track 22 needs to be adjusted, once the cam 33 is rotated to make the rack 32 lose the limit, the rack 32 can automatically disengage from the first engaging tooth 31 under the action of the spring 35, thereby reducing the abrasion caused by dragging between the rack 32 and the first engaging tooth 31, and simultaneously reducing the adjusting resistance and the noise.

As shown in fig. 3 and 5, the adjusting lever 24 includes a first straight lever 242 having one end extending into the cavity 34 and fixedly connected to the cam 33, a second straight lever 243 movably connected to the other end of the first straight lever 242, and a lever sleeve 241 sleeved outside the first straight lever 242 and the second straight lever 243, wherein a locking mechanism is disposed at a movable connecting end of the first straight lever 242 and the second straight lever 243, and the locking mechanism limits the relative rotation between the first straight lever 242 and the second straight lever 243 when the second straight lever 243 is axially close to the cam 33 and slides to a limited position, and releases the limitation on the relative rotation between the first straight lever 242 and the second straight lever 243 when the second straight lever 243 is axially far away from the cam 33 and slides to an original position.

Because the rotation of the cam 33 is controlled by the adjusting rod 24, it is necessary to ensure that the cam 33 does not accidentally touch the adjusting rod 24 in the operating state to cause the rotation of the cam 33, thereby affecting the normal operation of the ash removal rapping device, the rod sleeve 241 is used for protecting the connection structure of the first straight rod 242 and the second straight rod 243 inside, so the adjusting rod 24 is arranged into the connection structure of the first straight rod 242 and the second straight rod 243, thus when the cam 33 needs to be controlled, only the second straight rod 243 is pushed inwards, i.e. the second straight rod 243 slides to a position close to the cam 33 along the axial direction, the relative rotation of the first straight rod 242 and the second straight rod 243 is limited, and at this time, the second straight rod 243 can be rotated to drive the first straight rod 242 so as to control the rotation of the cam 33; when the cam 33 does not need to be controlled, the second straight rod 243 needs to be pulled outwards, that is, the second straight rod 243 axially moves away from the cam 33 and slides to the original position, the relative rotation limitation between the first straight rod 242 and the second straight rod 243 is removed, and no matter how the second straight rod 243 rotates, the first straight rod 242 cannot be driven to rotate, so that the occurrence of misoperation is avoided, and the production safety is guaranteed.
