Disclosed is a column fixing device of a frost prevention machine, comprising a frost prevention machine (1), a connection support (2), a pedestal (3) and a pedestal bolt (4). The connecting support (2) comprises an anti-tilting guide barrel (21), a fixed pillar (22), a rib plate (23), and a connecting plate (24). The pedestal (3) is composed of pedestal plates (31) spliced to each other, and adjacent pedestal plates are connected via double-end studs (32). The pedestal bolt (4) is used for fixedly connecting the connecting support (2) with the pedestal (3). The pedestal is driven into soil to fix the pedestal, then the frost prevention machine is fixed through the pedestal and the connection support so as to overcome the difficulty and low efficiency of digging small-diameter installation deep holes required for high precision. In addition, due to application of the connection support, original non-standard pipes selected to satisfy the height of the frost prevention machine can be replaced by standard pipes, greatly saving on material cost, and also facilitating transportation and storage. The frost prevention machine column fixing device is simple in structure and convenient to install, and not only is labour intensity for installation, capabilities of sink-resistance, horizontal torsion resistance and tilt resistance for a frost prevention machine column are improved, and working reliability of the frost prevention machine is increased, but installation and manufacturing costs of the frost prevention machine are also reduced, and installation efficiency and economic benefit of the frost prevention machine are improved.L'invention porte sur un dispositif de fixation de colonne d'une machine de prévention du givre, comprenant une machine de prévention du givre (1), un support de connexion (2), un socle (3) et un boulon de socle (4).
