Description

Technical Field

[0001] This utility model relates to the technical field of fruit tree cold-resistant equipment, and more specifically to a water spraying device for cold-resistant hardening of fruit trees. Background Technology

[0002] As one of my country's important fruit tree industries, the apple industry occupies a pivotal position in the agricultural economy. my country has a vast territory with complex and diverse geographical and climatic conditions, and apple trees face numerous challenges during their growth. Among these, low-temperature chilling injury is one of the key factors seriously affecting the development of the apple tree industry.

[0003] Among the many types of low-temperature damage, late spring frosts are particularly prominent. Every spring (March to May), temperatures often rise rapidly in the early stages, leading crops such as apple trees to mistakenly believe that the warm season has arrived and begin their active growth phase. However, at this time, cold air may suddenly move southward, causing a sharp drop in temperature later on. This drastic temperature change can cause severe frost damage to crops. For apple trees, the harm caused by late spring frosts is multifaceted. Low temperatures inhibit photosynthesis in apple trees, reducing the accumulation of photosynthetic products and affecting the tree's energy supply; at the same time, it also hinders the absorption and transport of nutrients by the fruit trees, leading to nutritional imbalances. More seriously, low temperatures may trigger abnormal physiological functions in apple trees, resulting in adverse phenomena such as flower and fruit drop, bolting, etc., greatly reducing the yield and quality of apples and causing huge economic losses to fruit farmers.

[0004] To combat the damage to fruit trees caused by late spring frosts or low temperatures, fruit growers have long employed a series of traditional protective measures, such as spraying growth regulators, antifreeze agents, and heat-insulating fumigants. While these methods offer some protection, they also have numerous drawbacks. On the one hand, the use of these chemical agents increases the growers' costs, including the purchase and maintenance of pesticides and spraying equipment. On the other hand, long-term, excessive use of chemical agents may pose safety hazards to fruit trees. For example, pesticide residues may affect the quality and safety of apples, damage the soil ecosystem, leading to soil compaction, a reduction in beneficial microorganisms, and ultimately, hindering the long-term healthy growth of apple trees.

[0005] Given the limitations of traditional protective measures, it is particularly important to provide a device that artificially simulates a frozen environment to enhance the cold resistance of fruit trees, stimulate their own cold resistance mechanisms, and improve their cold tolerance. Utility Model Content

[0006] This invention provides a water spraying device for cold-resistant hardening of fruit trees, in order to solve the problems existing in the above-mentioned background art.

[0007] To solve the above-mentioned technical problems, the technical solution of this utility model is as follows: A water spraying device for cold-resistant hardening of fruit trees includes a support assembly. Four sets of the support assemblies are symmetrically arranged and connected to form a bracket by connecting rods. Spraying components are mounted on the connecting rods and are symmetrically arranged on the bracket by adjusting components. A temperature sensor is mounted on the lower part of one set of the support assemblies and is electrically connected to the spraying components.

[0008] The support assembly includes four first support rods. Each of the four first support rods is slidably connected to a first extension rod via an adjustment knob. The tops of the four first extension rods are fixedly connected to each other via a connecting rod to form a bracket.

[0009] The adjustment assembly is provided in four sets, all of which are fixedly installed in the middle position of the connecting rod. The adjustment assembly includes a second support rod, and the second support rod is slidably connected to a second extension rod through an adjustment knob. The end of the second extension rod away from the second support rod is fixedly connected to the spray assembly.

[0010] The spray assembly includes a spray pipe, a spray head, a water supply pipe, and a water delivery pipe. The spray pipe is a flexible metal hose, with one end connected to the spray head and the other end connected to the water supply pipe.

[0011] Furthermore, all four water supply pipes are connected to the water transmission pipe.

[0012] Furthermore, a control switch is installed at the end of the water supply pipe near the spray pipe.

[0013] Furthermore, the water supply pipe is equipped with an electromagnetic switch, which is electrically connected to a temperature sensor.

[0014] Furthermore, a rotating cylinder is threadedly connected to the bottom of the first support rod, a helical blade is fixedly provided on the outside of the rotating cylinder, and a handle is symmetrically provided on the top outer side of the rotating cylinder.

[0015] This utility model has the following beneficial effects: (1) The bottom of the first support rod of this utility model is equipped with a rotating drum and a rotating handle with spiral blades. When installing, the first support rod can be easily inserted into the ground by rotating the rotating handle, which improves the installation efficiency. At the same time, the support component and the adjustment component can be flexibly adjusted by adjusting knob one and adjusting knob two respectively, as well as the distance between the support and the fruit tree and the spray component. The spray angle can also be adjusted by using the metal flexible hose spray pipe, which can well adapt to the height and shape changes of the fruit tree during the growth process and meet the water spraying needs of different growth stages.

[0016] (2) The temperature sensor of this utility model is electrically connected to the electromagnetic switch, which can monitor the surface temperature of the fruit tree canopy in real time. When the temperature is lower than the set value, the electromagnetic switch is automatically turned on to supply water through the water pipe and spray water automatically to maintain the plant surface ice to form artificial freezing stress. Moreover, the control switch on the water supply pipe can control the water supply of each spray pipe individually to achieve precise water spraying, which helps to better carry out the cold resistance training of fruit trees and enhance the cold resistance of fruit trees.

Detailed Implementation

[0018] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings. It should be noted that these descriptions are for the purpose of aiding understanding of this utility model, but do not constitute a limitation thereof. Furthermore, the technical features involved in the various embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0019] A water spraying device for hardening fruit trees against cold, as shown in the attached image. Figure 1-4 As shown, the system includes a support assembly, of which four sets are symmetrically arranged. The four sets of support assemblies are connected to form a bracket 1 via connecting rods 2. A spray assembly is mounted on the connecting rods 2. The spray assembly is symmetrically arranged on the bracket 1 via an adjustment assembly. A temperature sensor 3 is mounted on the lower part of one set of support assemblies. The temperature sensor 3 is electrically connected to the spray assembly.

[0020] The support assembly includes four first support rods 4. Each of the four first support rods 4 is slidably connected to a first extension rod 6 via an adjustment knob 5. The tops of the four first extension rods 6 are fixedly connected to each other via a connecting rod 2 to form a bracket 1. By adjusting the knob 5, the position of the first extension rod 6 on the first support rod 4 can be adjusted, thereby changing the height of the bracket 1 to adapt to the height changes of the fruit tree during its growth process and to make adaptive adjustments for the cold resistance training of the fruit tree.

[0021] The adjustment assembly has four sets (obviously, the specific number can be appropriately increased according to the actual situation), all fixedly set in the middle position of the connecting rod 2. The adjustment assembly includes a second support rod 7, and the second support rod 7 is slidably connected to a second extension rod 9 through an adjustment knob 8. The end of the second extension rod 9 away from the second support rod 7 is fixedly connected to the spray assembly (in this embodiment, the spray assembly is also set to four sets accordingly, obviously, the specific number can also be appropriately increased according to the actual situation); by adjusting the knob 8, the position of the second extension rod 9 on the second support rod 7 can be adjusted, thereby adjusting the distance between the spray assembly and the fruit tree, making the water spraying more precise.

[0022] The spraying assembly includes a spray pipe 10, a spray head 11, a water supply pipe 12, and a water delivery pipe 13. The spray pipe 10 is a flexible metal hose, which can adaptively adjust the spray angle to meet the morphological changes of the fruit tree during its growth. One end of the spray pipe 10 is connected to the spray head 11, and the other end is connected to the water supply pipe 12. In this embodiment, the spray head 11 is an atomizing spray head. All four water supply pipes 12 are connected to the water delivery pipes 13 for centralized water supply. A control switch 14 is provided at the end of the water supply pipe 12 near the spray pipe 10 to control the water supply of each spray pipe 10 individually. An electromagnetic switch 15 is provided on the water delivery pipe 13. The electromagnetic switch 15 is electrically connected to a temperature sensor 3, which monitors the surface temperature of the fruit tree canopy. When the temperature sensor 3 detects that the temperature is lower than the set value, the electromagnetic switch 15 is turned on, and the water delivery pipe 13 starts to supply water, realizing automatic water spraying to keep the plant surface in a frozen state.

[0023] Furthermore, a rotating cylinder 16 is threadedly connected to the bottom of the first support rod 4. A spiral blade 17 is fixed on the outside of the rotating cylinder 16, and a handle 18 is symmetrically arranged on the top outside of the rotating cylinder 16. When the first support rod 4 is inserted into the ground, the rotating cylinder 16 can be rotated by rotating the handle 18. The spiral blade 17 on the outside of the rotating cylinder 16 can more easily insert the first support rod 4 into the ground, thus improving installation efficiency.

[0024] It should be noted that the apple trees selected for cold resistance training in this embodiment are of the Fuji variety. Before the apple trees sprout, when the natural low temperature reaches 0°C to 1°C, artificial water is sprayed onto the apple trees in the open environment to cause the surface of the fruit tree plants to freeze, forming a continuous artificial freezing stress. The temperature range of the artificial freezing stress is -2°C to -8°C, and the duration is 5 to 12 hours. Preferably, the duration of the artificial freezing stress is 8 to 12 hours. More preferably, the duration of the artificial freezing stress is about 8 hours. The specific implementation process of this device will be further described below.
