The machine (1) comprises a motorized chassis on which units are mounted in form of head for harvesting pollen by suction, parallelly arranged suction circuits (4, 5), and a unit for freezing pollens collected in recovery unit. The motorized chassis is connected through a unit in the form of cyclone in which the unit is associated with other unit in form of hopper (9) for collecting pollens. The units in form of head for harvesting pollen comprise a suction hoods having a first portion in conical form.

The motorized chassis is connected through a unit in the form of cyclone in which the unit is associated with other unit in form of hopper (9) for collecting pollens. The units in form of head for harvesting pollen comprise a suction hoods having a first portion in conical form widening between an opening for connecting to the rest of the circuits of the machine and a square-shaped polygonal base. The suction hoods are arranged in the form of a suction ramp (3) carried by a fork (2) adjustable in upper position and fixed to the front of the machine. One of the suction circuits is connected with hoods of the left and the other with hoods on the right side of the suction ramp, where circuits comprise a unit in the form of separating cyclone, a unit in the form of suction fan and a unit in the form of hopper for collecting pollen. The unit in hopper form comprise a hopper around which an insulation is laid, a trap for introducing dry ice, and a unit for injecting liquid nitrogen, where a bottom of unit in hopper form comprises a trap door.Cette machine de récolte de pollens du type comportant un châssis motorisé sur lequel sont montés des moyens en forme de tête de récolte par aspiration des pollens, raccordés à travers des moyens en forme de cycl
