Description

Technical Field

[0001] The utility model relates to the field of pear tree antifreeze spraying equipment, and more specifically, to an antifreeze liquid spraying device for antifreeze of pear tree blossoms. Background Art

[0002] Pear trees are perennial deciduous fruit trees of the genus Pyrus in the Rosaceae family. They are widely distributed around the world. Pear fruit is edible and has high nutritional and medicinal value. However, during the current planting period of pear gardens, when the spring temperature is low and the late spring cold comes, the anti-freeze measures for pear trees mainly include the following aspects:

[0003] Irrigation to cool ground temperatures: Watering the pear orchard thoroughly 7-10 days before flowering can improve air and soil temperatures, lower ground temperatures, delay flowering by 3-5 days, and mitigate the effects of a late spring cold snap. Watering the entire orchard 1-2 days before a cold snap increases soil moisture, heat capacity, and thermal conductivity, allowing it to store more heat for release, slowing the drop in nighttime temperatures and preventing frost.

[0004] Fumigation to prevent cold: Between 2 and 6 a.m. on the day of the cold wave, when the temperature drops to around 1°C, light wet firewood around the orchard to form a protective layer of smoke. Keep it there until the sun rises and the temperature rises to avoid the cold wave.

[0005] Spray nutrient antifreeze agents: 1-2 days before the temperature drops, spray potassium dihydrogen phosphate, amino acid calcium, fluid boron, etc. to increase the cell sap concentration of flower organs, young fruits and branches, and enhance antifreeze ability.

[0006] However, among the existing antifreeze measures, watering to lower the ground temperature can only be done the day before or on the day of the late spring cold snap. This method is only suitable for irrigation of small areas (about ten acres). For example, when flooding a large pear orchard, the irrigation time required is long, and it is impossible to implement antifreeze measures for all pear trees in time.

[0007] Fumigation measures are greatly affected by environmental factors, and the human burden is further increased;

[0008] As for spraying nutrient antifreeze agents, due to the height limit of pear trees, it is difficult for personnel to spray the high branches of pear trees. They need to climb and other work, which can easily cause safety hazards. At the same time, in a large pear orchard, it takes a lot of time and manpower to complete the antifreeze spraying operation on the pear trees in a short time, and the efficiency is relatively slow.

[0009] To this end, in view of the above-mentioned existing defects, this solution proposes an antifreeze spray device for preventing pear trees from freezing during flowering. Utility Model Content

A ground spraying member 8 is installed at the lower end of the connecting rope 7. Water pipes 9 are installed between the delivery pump 1 and the aerial spraying member 4 and between the aerial spraying member 4 and the ground spraying member 8.

[0040] During the use of this solution, in order to enable the existing large-scale pear trees to be able to take antifreeze measures in a relatively short time and with high efficiency, in this embodiment, by putting the hook 2 on the branches of each pear tree, and according to the angle of the antifreeze liquid to be sprayed, the positioning member 3, the aerial spraying member 4 and the lower side of the hook 2 are put on, and then the nut 5 is screwed in according to the thickness of the pear branch, so that the positioning member 3 or the aerial spraying member 4 is pressed against the lower side of the pear branch, thereby achieving positioning on the branches of each pear tree, and then the water pipe 9 is respectively It is connected with the delivery pump 1, the aerial spraying part 4, and the ground spraying part 8. Subsequently, the delivery pump 1 only needs to deliver the antifreeze liquid from the inside of the box to the aerial spraying part 4 and the ground spraying part 8, so as to realize the atomization and spraying of the antifreeze liquid to the surface of each branch of the pear tree, and complete the antifreeze measures for the pear tree. It enables personnel to carry out short-time and efficient antifreeze liquid spraying operations in large-scale pear tree planting areas, greatly improving the work efficiency of personnel, eliminating the need for personnel to take antifreeze measures for pear trees one by one, and reducing the labor burden.

[0041] Compared with existing technologies, this solution reduces the time it takes for personnel to complete antifreeze protection measures in large pear plantations from a week or more to 3-5 hours, thus achieving automated antifreeze spraying operations, greatly reducing manpower and completing the spraying operation efficiently.

[0042] At the same time, in this embodiment, the personnel can also realize the delivery of water, fertilizer, insect repellent and water through the delivery pump 1, thereby realizing the operations of fertilizing, repelling insects and cooling the pear trees in daily life, with wider functionality.

[0045] During use of this solution, personnel can, according to the specific antifreeze spraying range, either position the positioning member 3 or the aerial spraying member 4 on the lower side of the pear tree branch to be fixed, so that it is positioned at the outer end of the pear tree branch;

[0046] During use, if the personnel place the positioning member 3 under the branch and the aerial spraying member 4 under the positioning member 3, the personnel can screw in the nut 5 to cause the positioning member 3 to be pressed against the bottom of the branch for positioning, and the aerial spraying member 4 can adjust the spraying range of the antifreeze liquid by rotating the angle. Finally, when the nut 5 is screwed in, the positions of the positioning member 3 and the aerial spraying member 4 are fixed to achieve the limitation of the spraying range of the antifreeze liquid.

[0047] If the personnel do not need to press the positioning member 3, the spraying range is just within the range of the aerial spraying member 4. The personnel only need to put the aerial spraying member 4 on the outside of the hook 2, remove the positioning member 3, and then only need to screw in the nut 5 to complete the positioning of the aerial spraying member 4 on the pear tree branch. The use method is more flexible.

[0050] During use of this solution, when the antifreeze liquid is transported inside the four-way valve tube 44, the antifreeze liquid is sprayed outward from the liquid outlet 442, then hits the frustum end of the ejector pin 443 to form a mist, and then sprays on the surface of the pear tree, completing the antifreeze liquid spraying operation;

[0051] In this embodiment, the diameter of the liquid outlet hole 442 is set at 0.3 mm.

[0052] See also Figure 1-2 and Figure 4 The ground spraying member 8 includes a second liquid discharge tube 81 fixedly connected to the lower end of the connecting rope 7, and a liquid inlet pipe 82 is embedded in the upper end of the second liquid discharge tube 81.
