Special spreading machine for saline-alkali soil improvement material

The invention relates to the technical field of broadcasters, in particular to a special broadcaster for saline-alkali soil improvement materials, which comprises a rack, a water tank, an adjusting box, a sliding frame, a transmission box, a console, a pump body, a conveying pipe, a spray pipe, an adjusting mechanism, a rotating mechanism and a feeding mechanism. The distance between the spray pipes is adjusted through the adjusting mechanism, so that part of the device can be adjusted according to the distance between crops, the spray pipes can be conveniently aligned to the roots of the crops, rotation of the spray pipes is achieved through the rotating mechanism, part of the device can drive the spray pipes to rotate and spray around the crops, and uniform fertilization on the roots of the crops is facilitated; and synchronous feeding of the spraying pipes is achieved through the feeding mechanism, so that part of the device can rotate along with the spraying pipes for feeding, and the adjustability, stabi
