Description

TECHNICAL FIELD

[0001] The utility model relates to agricultural planting technical field, concretely relates to a cold fog humidification cooling and fertilization system for orchard. BACKGROUND

[0002] At present, with the rapid development of modern agriculture, orchard as an important agricultural production base, the demand for efficient and environmentally friendly spraying equipment is increasingly urgent.

[0003] The main method of traditional orchard cooling includes artificial timely water supply, sunshade, covering tree disc and other measures. The main way of traditional orchard humidification includes irrigation, covering tree disc, reducing pruning, tree whitening and so on. The main method of traditional orchard spraying and fertilization includes powder spraying and ground scattering method, artificial spraying method, root application method and bottle burying method, high pressure injection method and perfusion method, insect hole injection method and plugging method. The traditional orchard spraying and fertilization method needs the staff to enter the orchard to manually open and close the valve or directly carry the prepared pesticide or fertilizer spraying operation, and the staff works in the environment full of pesticide or fertilizer for a long time, which is difficult to avoid the adverse effects on the staff's body even if certain protective measures are taken. The traditional orchard humidification, cooling, spraying and fertilization method has the problems of low efficiency, poor uniformity of coverage, high labor cost and other measures, which can not meet the needs of modern orchard planting.

[0004] The Chinese patent with publication number CN205375248U discloses a smart agricultural control and management system based on Internet of Things, which can not only understand the outdoor weather conditions in time, but also facilitate managers to remotely monitor the growth state of agricultural crops, and is more convenient and efficient. The central controller is connected with an irrigation system, a fertilization system and an inflation system, which can irrigate agricultural crops in time to prevent water shortage and affect growth, and can conveniently fertilize agricultural crops, greatly saving manpower. When the air pressure in the agricultural greenhouse decreases, the inflation system can supplement the air for the agricultural greenhouse in time, so that the agricultural crops can maintain a good growth state for a long time. However, on the one hand, the system lacks a targeted spraying system for orchards with large area, and the water output of the irrigation system is too large, so it is not suitable for orchards. On the other hand, since the orchard occupies a large area, only understanding the weather conditions is not enough to reflect whether the growth state of the fruit trees in the orchard is good.

[0005] Therefore, we propose a system with wide spraying range, eliminating safety hazards for workers, and reducing management and use costs. Utility model content

[0037] Example 1

[0038] As attached Figure 1 The cold mist humidification, cooling and fertilization system for an orchard shown in the figure comprises a pressurized filtration unit 1, a fertilizer and dosing filtration unit 2, a high-pressure cold mist unit 3, a park pipeline unit 4 and a control unit 5;

[0039] The pressurized filtration unit 1 is used to pressurize and filter the water source; pressurization can facilitate the implementation of subsequent atomization operations, while filtration improves water quality and reduces the burden on subsequent pipelines and equipment;

[0040] The fertilizer and drug adding and filtering unit 2 is used to receive the treated water source and mix the corresponding fertilizer liquid or drug liquid; the components in the fertilizer liquid are capable of being absorbed by the fruit tree leaves and integrated into the soil, while the drug liquid is a general drug liquid component for pest control;

[0041] The high-pressure cold mist unit 3 is used to atomize the treated water source, fertilizer liquid or liquid medicine and output it to the park pipeline unit 4; when the water-dynamic fixed-proportion fertilizer spreader 21 is not working, that is, when no fertilizer liquid or liquid medicine is prepared, the water source output by the pressurized filtration unit 1 can directly enter the high-pressure cold mist unit 3 for atomization; when the water-dynamic fixed-proportion fertilizer spreader 21 is working, that is, when the fertilizer liquid or liquid medicine is prepared, the high-pressure cold mist unit 3 atomizes the corresponding fertilizer liquid or liquid medicine;

[0042] The park pipeline unit 4 is provided with a plurality of high-pressure all-stainless steel cold mist nozzles for spraying the atomized liquid onto the fruit trees;

[0043] In the park pipeline unit 4, the orchard is first divided into multiple large areas according to the terrain and area, and then each large area is divided into multiple small areas according to the density of the fruit trees. The pipeline is set up as follows: the field main pipes in the orchard large area are all made of high-pressure PE pipes with white outer surface and black inner surface, and the branch pipes and terminal pipes are all made of PA nylon high-pressure pipes with white outer surface and black inner surface or high-pressure stainless steel pipes, and are installed step by step in each orchard small area. In addition, during installation, the high-pressure main pipes must be buried in a pipeline trench at least 0.2m deep; the remaining high-pressure branch pipes and terminal pipes are all installed on the exposed surface. In particular, the sprinklers are high-pressure ruby ​​striker cold mist nozzles or high-pressure all-stainless steel cold mist nozzles.

[0044] The control unit 5 is used to collect environmental data and soil data, and control the high-pressure cold fogging unit 3;

[0045] The control unit 5 controls the humidification and cooling, the fertilization and the pesticide spraying in the following way: the humidification and cooling, the fertilization and the pesticide spraying are carried out in the cold fogging zones in turns, and the duration of the humidification and cooling, the fertilization and the pesticide spraying is determined according to the environmental data and the soil data;

[0046] That is, in the humidification and cooling process, when the current humidity and temperature reach the required value according to the environmental data, the high-pressure cold fogging unit 3 stops the humidification and cooling operation; when the current soil fertility is determined to be insufficient according to the soil data, the fertilizer and pesticide filtering unit 2 works to accurately adjust the amount of fertilizer liquid, and then the high-pressure cold fogging unit 3 sprays the fertilizer liquid to fertilize the soil;

[0047] In addition, since the fruit tree pests are randomly and continuously generated, the adjustment of the pesticide liquid is carried out at a fixed time, that is, independently of the humidification and cooling and the fertilization operation.

[0048] In addition, the system has three operation modes:

[0049] The first mode is manually opened and closed, that is, the manual control knob in the control unit 5 or the mobile phone APP is temporarily controlled.

[0050] The second mode is to program the time opening and closing on the host, and send instructions to the control unit 5 according to the set time program to realize automatic operation.

[0051] The third mode is to use the existing humidity and temperature sensors of the automatic control system of the Internet of Things, and set the automatic control system as "adjustable according to the soil temperature and humidity of the park or the air temperature and humidity of the park" as the control instruction to control the automatic operation of the cold fog humidification and cooling and fertilization system.

[0052] According to the needs, different management personnel requirements are realized according to different use scenarios, different control function options of the cold fog humidification and cooling and fertilization system are provided, the most suitable environmental conditions for crop growth are provided, and the efficiency and uniformity of the humidification and cooling and pesticide spraying and fertilization of the planting park are improved, and the management and use cost of the grower is reduced.

[0053] Example 2

[0054] The pressurized filtration unit 1 comprises a fabricated water storage tank 11, a water pump 12, a first filter 13 and a second filter 14 connected in sequence, and the water outlet of the second filter 14 is connected with the fertilizer and pesticide adding filtration unit 2. By adopting the two-stage filtration mode, the impurities in the water source can be effectively filtered, so as to improve the quality of the water source, facilitate the absorption of the fruit trees in the subsequent humidification and cooling spraying, and reduce the damage of the impurities to the high-pressure cold fog machine set 3 and the park pipeline unit 4.

[0055] In addition, the first filter 13 is an automatic backwashing sand filter. The automatic backwashing function reduces the need for manual intervention, can automatically start the backwashing process under the condition of a set time or pressure difference, thereby ensuring the continuous and efficient operation of the filter. In addition, the automatic backwashing sand filter can complete efficient cleaning in a short time through an optimized backwashing design, thereby greatly reducing the consumption of cleaning water. In addition, since the automatic operation is realized, the workload and frequency of manual cleaning are reduced, thereby reducing the long-term operation cost. In addition, the automatic backwashing mechanism also helps to prolong the service life of the filter. Moreover, high-quality sand is used as the filter medium, which can effectively remove suspended solids, silt and other impurities in the water, so as to ensure that the water quality meets a high standard.

[0056] In particular, the second filter 14 is an automatic backwashing laminated filter. The automatic backwashing function can automatically detect the pressure difference change of the filter, and automatically start the backwashing process when the pressure difference reaches the preset value, without the need for manual intervention, thereby ensuring the continuous and efficient operation of the filter. In addition, the water consumption during the backwashing process is relatively small, because the cleaning is quickly completed under high pressure, thereby effectively reducing the consumption of cleaning water and improving the utilization rate of water resources. Moreover, the laminated filter adopts multiple layers of fine filter materials, which can effectively remove suspended solids, silt, algae and other impurities in the water, and the filtration precision is usually up to 130 microns or even higher, thereby ensuring that the water quality meets a high standard. In addition, the automatic backwashing function reduces the frequency and intensity of manual cleaning, thereby reducing the maintenance cost. In addition, the laminated design makes the replacement and cleaning more convenient and fast, thereby prolonging the service life of the equipment. In addition, the laminated filter has a compact structure and a small size, and is suitable for installation in a limited space.

[0057] Embodiment 3

[0058] The fertilizer and pesticide adding filtration unit 2 comprises a water-driven proportional fertilizer applicator 21, a fertilizer tank 22, a pesticide tank 23 and a third filter 24. The water inlet of the water-driven proportional fertilizer applicator 21 is connected with the water outlet of the pressurized filtration unit 1. The liquid inlets of the water-driven proportional fertilizer applicator 21 are respectively connected with the fertilizer tank 22 and the pesticide tank 23. The liquid outlets of the fertilizer tank 22 and the pesticide tank 23 are connected with the inlet of the high-pressure cold fog machine set 3 through the third filter 24.

[0059] The processed water source output by the pressure filtration unit 1, and when the orchard needs to be humidified and cooled, is directly output to the high-pressure cold fog machine set 3 for atomization through the water-driven proportional fertilizer applicator 21; when the fertilizer liquid or pesticide liquid needs to be prepared, the proportion of fertilizer or pesticide added from the fertilizer tank 22 and the pesticide tank 23 is controlled through the water-driven proportional fertilizer applicator 21, so that the required fertilizer liquid or pesticide liquid can be accurately prepared; and the water source, the prepared fertilizer liquid or pesticide liquid are filtered through the third filter 24, so that the purity of the liquid output to the high-pressure cold fog machine set 3 can be further improved, and damage to the high-pressure cold fog machine set 3 or blockage of the high-pressure all-stainless-steel cold fog nozzle caused by solid impurities can be prevented.

[0060] It should be noted that the water-driven proportional fertilizer applicator 21 is also called a hydraulic proportional pesticide adding pump.

[0061] In particular, the third filter 24 is a semi-automatic cleaning screen filter, which has the advantages of simple operation. The user only needs to manually start the cleaning process at regular intervals, and the device will automatically complete the cleaning action, reducing the operation difficulty. Compared with the fully automatic cleaning filter, the semi-automatic cleaning screen filter has a relatively simple structure and lower maintenance cost. Manually starting the cleaning process reduces the dependence on complex automatic control systems and reduces the cost of repairing and replacing parts. In addition, users can flexibly choose the timing of cleaning according to actual conditions and needs, avoiding unnecessary cleaning operations caused by fixed cleaning cycles in fully automatic systems, thereby saving water resources and energy. In addition, the use of precise screen filter material can effectively remove suspended solids, silt, algae and other impurities in water, ensuring that the water quality meets high standards. The filtration accuracy is usually up to 130 microns or even higher.

The receiving end of the controller 53 is wirelessly connected to the outdoor weather station 51 and the soil moisture monitor 52, i.e., using wireless communication to realize information transmission between the controller 53 and the outdoor weather station 51 and the soil moisture monitor 52. The output end of the controller 53 is wiredly connected to the high-pressure cold fog machine set 3, i.e., using cable or other wired communication to realize information transmission between the controller 53 and the high-pressure cold fog machine set 3, and to achieve the purpose of the controller 53 controlling the action of the high-pressure cold fog machine set 3.

[0064] The outdoor weather station 51 is used for collecting environmental data such as outdoor temperature, outdoor humidity, outdoor illumination, outdoor wind speed, outdoor wind direction, outdoor rain and snow, outdoor atmospheric pressure, rainfall and total solar radiation data;

Through the APP, the growth of fruit trees and the pest and disease conditions in the orchard can be viewed in real time. Through the APP software, the user and the Internet of Things system are more closely connected.

[0067] When the fruit orchard cold fog humidification and cooling and fertilization system is implemented, firstly, the water source is subjected to a preliminary pressurization and filtration operation by the pressurization and filtration unit 1, then the fertilizer and medicine adding and filtration unit 2 selects whether to perform a fertilizer and medicine adding operation according to the situation, if the fertilizer and medicine adding operation is performed, the processed fertilizer liquid or medicine liquid is filtered and then enters the high-pressure cold fog machine set 3, if the fertilizer and medicine adding operation is not performed, the preliminary pressurized water source directly enters the high-pressure cold fog machine set 3;

[0068] Then, the control unit 5 controls whether the high-pressure cold fog machine set 3 is started according to the weather and soil data, that is, whether the corresponding liquid is output to the orchard pipeline unit 4 for atomization and spraying;

[0069] It should be noted that whether the fertilizer and medicine adding and filtration unit 2 performs the fertilizer and medicine adding operation according to the situation depends on whether the water-driven proportional fertilization machine 21 works.

[0070] The above is only a preferred embodiment of the present application, and is not used to limit the present application. For those skilled in the art, the present application can have various changes and modifications.
