Double-effect breakpoint type spray welding device for alloy powder

The invention discloses a double-effect breakpoint type spray welding device for alloy powder. The device structurally comprises a spray welding reaction chamber and a circulating feeding port; and the middle part of the bottom end of the spray welding reaction chamber is connected with a soil outlet in a cuttage grafting manner. The device has the following beneficial effect of solving the problems that the subsequent working efficiency is low and the bucket teeth of the excavators are secondarily damaged as the bucket teeth collide with the rocks to cause bucket teeth depressions and incompletion during the use, the repair welding effect is bad and the water resource is waste as the surfaces of the bucket teeth of the excavators cannot be cleaned up by water, and the comprehensive repairwelding cannot be carried out on the bucket teeth at once through manual welding. During the use, the positions, needing repair welding, of the bucket teeth are adjusted through an omnibearing spraywelding mechanism, the rec
