Abstract

A column fixing device for frost prevention machine includes a connecting support, a pedestal, and pedestal bolt. The connecting support is composed of an anti-tilting guide barrel, a fixed pillar, a rib plate, and a connecting plate. The pedestal is composed of pedestal plates spliced to each other, and adjacent pedestal plates are connected via double-end studs. The pedestal bolt is used for fixedly connecting the connecting support with the pedestal. The pedestal is hit into soil to fix the pedestal, and then the frost prevention machine is fixed through the pedestal and the connecting support so as to overcome the difficulty and low efficiency of digging small-diameter installation deep holes required for high precision.

Claims

1. A column fixing device adapted for a frost prevention machine, the column fixing device comprising a connecting support, a pedestal, and a pedestal bolt, wherein the connecting support is composed of an anti-tilting guide barrel, a fixed pillar, a rib plate, and a connecting plate, the pedestal is composed of a plurality of pedestal plates spliced to each other, and adjacent pedestal plates are connected via double-end studs;

the pedestal bolt is used for fixedly connecting the connecting support and the pedestal,

wherein the pedestal plates respectively have L-shaped holes at an edge thereof, an adjacent two of the pedestal plates are connected via the double-end studs through the L-shaped holes;

the double-end studs will not slide out of the L-shaped holes under an upward resistance of soil when the pedestal is punched into the soil, and the double-end studs will tightly couple the adjacent two of the pedestal plates together.

2. The column fixing device for frost prevention machine according to claim 1, wherein an outer diameter of the anti-tilting guide barrel is 0.5 millimeters-1 millimeter smaller than an inner diameter of a frost prevention machine column and an inner diameter of the fixed pillar, an outer diameter of the fixed pillar is equal to an outer diameter of the frost prevention machine column.

3. The column fixing device for frost prevention machine according to claim 2, wherein two ends of the anti-tilting guide barrel are provided with chamfer to facilitate installation of the anti-tilting guide barrel and the frost prevention machine;
