The warhead can do linear reciprocating motion under the drive of first actuating mechanism to strike the face of waiting to rust cleaning repeatedly and remove rust, in order to avoid first actuating device to interfere the lift of warhead, tubular shell, first actuating device can be the rectilinear motion actuating mechanism such as the pneumatic cylinder of setting in tubular shell, also can be the air distribution mechanism, tubular shell is the open cavity this moment, warhead lateral wall offsets with tubular shell's inner wall and makes the interior atmospheric pressure of open cavity and external atmosphere separate, the air distribution mechanism is linked together with the open cavity, the air distribution mechanism lets in gas drive warhead to the face of waiting to rust cleaning to the open cavity, the warhead takes place to rebound after striking the face of waiting to rust cleaning, the tip of warhead is provided with tool bit 8 of being convenient for rust cleaning. In addition, in order to retrieve the rust knocked down from the face of waiting to rust removal, the derusting machine still includes negative pressure generating device 10 and sets up in rust recovery mouth 9 of warhead one side, negative pressure generating device 10 with rust recovery mouth 9 intercommunication to the rust that drops from the face of waiting to rust removal can be inhaled to rust recovery mouth 9. The negative pressure generating device 10 is a prior art, and the working principle thereof can be referred to as a vacuum cleaner.
The outer side wall of the tubular shell is provided with a threaded track 6, the spiral elastic piece 1 is sleeved on the tubular shell, and the positions of the spiral elastic piece 1 and the threaded track 6 are relatively matched; the transmission gear 3 is horizontally arranged above the spiral elastic piece 1, the transmission gear 3 is rotatably arranged in the derusting machine, the end face of the transmission gear 3 without the meshing teeth is connected with one end of the spiral elastic piece 1, the meshing teeth are arranged on the periphery of the transmission gear 3, the output shaft of the second driving device 4 is arranged on the periphery outer side provided with the meshing teeth, the meshing teeth are also arranged on the output shaft, the output shaft is meshed with the transmission gear 3, and the second driving device 4 can drive the transmission gear 3 to rotate through the output shaft, so that the spiral elastic piece 1 is driven to rotate. The spiral elastic piece 1 and the threaded track 6 are smooth, and the friction force is small, so that the tubular shell does not rotate when the spiral elastic piece 1 rotates, the spiral elastic piece 1 rotates relative to the threaded track 6, the tubular shell is driven to lift, and the principle is similar to a screw-nut mechanism. Because one end of the spiral elastic piece 1 is arranged on the transmission gear 3, and the transmission gear 3 is arranged in the derusting machine, the bullet type derusting mechanism can generate vibration, and in the process that the bullet type derusting mechanism transmits the vibration to the derusting machine, the spiral elastic piece 1 counteracts part of the vibration, and finally the vibration transmitted to the derusting machine can be effectively reduced, so that the function of damping can be realized.
