In order to realize the purpose, the utility model discloses a technical scheme as follows: a square tube internal blowing device comprises a square internal blowing nozzle, wherein the square internal blowing nozzle is provided with a square cavity, one end of the square internal blowing nozzle is arranged as an internal blowing end, the other end of the square internal blowing nozzle is arranged as a connecting end, a hollow threaded rod is arranged on the connecting end, one end of the hollow threaded rod is communicated with the square cavity, and the other end of the hollow threaded rod is in threaded connection with a guide device;
the guide device comprises a connecting pipe, a connecting plate is arranged on the side wall of the connecting pipe, two support plates are arranged on the connecting plate, a roller shaft is arranged between the end parts of the two support plates, and a roller is arranged on the roller shaft;
when the guide device is installed on the square inner blowing nozzle, the roller is arranged in the diagonal direction of the square inner blowing nozzle.
As an optimized technical scheme, a chamfer is arranged on the periphery of the inner blowing end, and a plurality of air blowing holes communicated with the square cavity are formed in the chamfer.
As a preferable technical scheme, the support plate is of a length-adjustable structure.
As a preferable technical scheme, when the square inner blowing nozzle works, one diagonal line of the square inner blowing nozzle is vertical to the ground.
The utility model discloses an useful part lies in:
(1) the utility model discloses a blow gun has realized the interior blowing of square pipe in the square, and has guaranteed with the help of guider that blow gun can not be along with stretching into the increase of length in the square, blow quality in blow gun and the contact of square intraductal wall in blow nozzle in leading to square because of the weight of blow gun itself in the square, but also avoided the interior blowpipe to take place the cost increase problem that flagging deformation caused.
(2) The utility model discloses square pipe's transmission conveys with the help of V type roller, and consequently square pipe's a diagonal is perpendicular to V type roller central line, and the utility model discloses blow gun during operation in square, blow gun's a diagonal and ground vertical in square, consequently can just in time match completely with square pipe, and the gyro wheel setting blow gun diagonal direction in square, guaranteed that the gyro wheel can with square intraductal wall below diagonal roll laminating to blow gun in supporting square.
