Grape frost prevention device suitable for vineyard

Abstract

The invention relates to the technical field of grape planting, and discloses a grape frost prevention device suitable for a vineyard. The grape frost prevention device comprises two supporting columns and an air heater, wherein a sliding rod is jointly and fixedly connected to the positions, close to the upper ends, of the two supporting columns, a plurality of sliding sleeves are connected to the sliding rod in a sliding mode, adjusting mechanisms are installed between the sliding sleeves and the sliding rod, a guide pipe fixedly communicates with the output end of the air heater, a plurality of branch pipes fixedly communicate with the guide pipe, air spraying heads fixedly communicate with the ends, away from the guide pipe, of the branch pipes, a positioning rod is fixedly connected to the lower end of the sliding sleeve, a first positioning rod is fixedly connected to the lower end of the positioning rod, a second positioning ring is hinged to one end of the lower portion of the first positioning ring, one end of the first positioning ring and one end of the second positioning ring are connected through a fixing mechanism, and the branch pipes are clamped between the first positioning ring and the second positioning ring. The grape frost prevention device suitable for the vineyard has the advantages that heat can be accurately supplied to grape vines, energy is saved, and frost prevention can be well carried out on grapes.

Description

technical field [0001] The invention relates to the technical field of grape planting, in particular to a grape anti-frost device suitable for vineyards. Background technique [0002] The anti-frost device for grapes in the vineyard is a protection device that prevents the grapes from being damaged by frost during the growth process, so that the grapes can not be affected by the frost during the night growth process. The existing market The anti-frost fan is often used to protect crops from frost, but it often happens that the temperature in the air cannot be raised well during the use process, which makes the entire anti-frost fan unable to be used very well. Good to achieve the desired effect, resulting in severe frostbite on the grapes at night. [0003] In the patent No. CN208159546U, a grape anti-frost device for vineyards is disclosed, which is provided with a storage bin, and then sawdust, sulfur, and weed guides can be placed inside the storage bin, and it can be re...
