The terminology used in the description herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. As used herein, the term "and/or" includes any and all combinations of one or more of the associated listed items.

One end of the bullet 12 is connected with the knocking mechanism body 11, the other end is a free end, the object to be knocked is close to the free end of the bullet 12, when the bullet 12 reciprocates, the free end of the bullet 12 knocks the object to be knocked (the material 800 is generally a metal plate such as a steel plate or an iron plate), and rust on the surface of the object to be knocked is removed through knocking vibration. At the moment when warhead 12 strikes material 800, material 800 is fixed by external force, and the amplitude of the whole vibrations of material 800 is less, therefore, compared with the existing knocking device, the noise that its production is less. Because the warheads 12 are uniformly distributed, the acting force during knocking is also uniformly distributed, and the knocking effect is also relatively stable.

Referring to fig. 3, in a preferred embodiment, the rapping device comprises a plurality of rapping modules 10 moving independently of each other, each rapping module 10 comprising a plurality of synchronously moving rapping mechanisms 1. During production, with the corresponding quantity strike the module 10 integrated together can, need not install production simple to operate with independent module 10 that strikes alone one by one. In the use, if certain module damages, the convenient dismantlement is changed, and it is more convenient to maintain.

In another preferred embodiment, the knocking device comprises a plurality of knocking modules 10 moving independently of each other, each knocking module 10 comprises a plurality of synchronously moving knocking mechanisms 1, and each knocking module 10 is connected with a valve train 3.

In the preferred embodiment, the striking mechanism mainly comprises a bullet 12, an air chamber 10, a buffer chamber 103, a valve train 3, a shock absorbing device, a rust block recovering device, a travel driving mechanism 15, and a driving mechanism 2.

Referring to fig. 3 and 7, in a further preferred embodiment, the air chamber 10 includes two parts, namely a guide through hole 101 and a piston chamber 102 at the lower part of the guide through hole 101, the buffer chamber 103 is a part of the piston chamber 102, a space enclosed by the end of the bullet 12 in the piston chamber 102 and the side wall of the piston chamber 102 is the buffer chamber 103, and the size of the space of the buffer chamber 103 changes with the movement of the bullet 12. Warhead 12 is installed in guide through hole 101 with liftable ground, and the laminating of warhead 12 lateral wall and guide through hole 101 inner wall makes piston chamber 102 not communicate with the external atmosphere.

The purpose is to prevent the bullet 12 from slipping off the guide through hole 101.

Referring to fig. 8, in the prior art, the gas distribution mechanism 3 is disposed at one side of the pressurizing station 104, and directly injects gas into the pressurizing station 104, which has the disadvantage that high-speed gas flow disturbs the movement of the bullet 12, so that the speed of the bullet 12 is reduced, the whole period of rebound after ejection is prolonged, the number of times of actuation of the bullet 12 per unit time is reduced, and an ideal knocking effect cannot be achieved. Therefore, the gas distribution mechanism 3 is arranged below the buffer cavity 103, the connecting lines of the buffer cavity 103, the piston cavity 102 and the guide through hole 101 are a straight line (the central axes thereof are positioned on the same straight line), and the gas outlet of the gas distribution mechanism 3 is staggered with the gas inlet of the gas channel 107, so that the buffer cavity 103 plays a primary buffer role, the kinetic energy of the sprayed gas is prevented from directly interfering the bullet 12, the bullet 12 is driven by the gas pressure, and the actuation times of the bullet 12 in unit time are favorably improved.
