DESCRIPTION OF THE EMBODIMENTS

(10) Referring to FIG. 1 and FIG. 1A, a column fixing device for frost prevention machine includes a connecting support 2 and a pedestal 3. The combined installation method meets height requirement and reliability requirement of the frost prevention machine. The frost prevention machine 1 is mounted on an anti-tilting guide barrel 21 of the connecting support 2 by a frost prevention machine column 11. The frost prevention machine 1 is fixed to the connecting support 2 by plug welding. The connecting support 2 and the pedestal 3 are fixed by the pedestal bolt 4.

(11) Referring to FIG. 2, the frost prevention machine includes a frost prevention machine column 11, a frost prevention machine blade 12, a frost prevention machine motor 13, and a frost prevention machine connection part 14. The frost prevention machine column 11 is a standard pipe with a length of 6 m.

(12) Referring to FIG. 4, the connecting support 2 includes an anti-tilting guide barrel 21, a fixed pillar 22, a rib plate 23, and a connecting plate 24 fixed to each other. An outer diameter of the anti-tilting guide barrel 21 is 0.5 mm-1 mm smaller than an inner diameter of the fixed pillar 22. Upper end of the fixed pillar 22 has 2 or 3 groups of small holes. Firstly, the anti-tilting guide barrel 21 is inserted into an upper end of the fixed pillar 22 around 200 mm. The anti-tilting guide barrel 21 and the fixed pillars 22 are fixed by plug welding. Secondly, the fixed pillar 22 is welded vertically in a center of the connecting plate 24, and then the rib plates 23 is welded between the fixed pillar 22 and the connecting plate 24 to enhance anti-dumping ability of the fixed pillar 22.
