Description

Technical Field

[0001] The invention relates to the technical field of agricultural machinery, and in particular to an intelligent spraying device based on chemical prevention and control of late spring frost for wheat. Background Art

[0002] In recent years, sensor technology has developed rapidly. Temperature sensors, humidity sensors, spectral sensors, etc., provide a wealth of information acquisition methods for intelligent spraying devices. These sensors can monitor the environmental information of wheat fields and the growth information of wheat in real time, providing data support for the precise control of intelligent spraying devices.

[0003] Late spring cold usually occurs in the period from the jointing stage to the heading stage of wheat. At this time, the wheat grows vigorously and its cold resistance gradually decreases. Low temperature will cause the growth and development of wheat to be hindered, and the leaves, stems, etc. of wheat will be damaged to varying degrees. Late spring cold during the heading stage will affect the differentiation and development of wheat spikelets, resulting in a decrease in the number of grains per ear and a lower fruit setting rate. Severe late spring cold may also cause a large number of infertile spikelets of wheat, and even cause a total wheat harvest. According to incomplete statistics, in years with severe late spring cold, wheat yield can be reduced by 20%-50%.

[0004] In conjunction with the above content, it should be explained that: Chinese patent with announcement number CN109180344A discloses a mixed preparation for resisting late spring frost of wheat and its preparation and spraying method. The spraying raw materials are mixed and sprayed in a simple container. There are too many uncertain factors. During actual use, a large amount of manpower and material resources are required. At the same time, it is easily affected by environmental factors, resulting in untimely spraying of large-scale wheat fields.

[0033] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0034] Example 1: Please refer to Figure 1 - Fig.10 As shown, this embodiment is an intelligent spraying device based on chemical prevention and control of late spring cold in wheat, comprising a storage barrel 1, a spraying base 2 is arranged at the bottom of the storage barrel 1, a cone disk 3 is arranged at the top of the storage barrel 1, an inner cylinder 101 is arranged inside the storage barrel 1, a limited cone ring 102 is slidably arranged on the inner wall of the top of the inner cylinder 101, a plurality of groups of ring suction frames 107 are arranged on the outer periphery of the inner cylinder 101, and a control panel is arranged on the outer peripheral wall of the storage barrel 1;

[0035] An aeration platform 201 is arranged at the top center of the spraying base 2, a bottom frame 206 is arranged at the bottom of the spraying base 2, and a bottom spray pump valve 205 and a main control motor 207 are arranged on the frame of the bottom frame 206. The external water source pipeline and the chemical agent pipeline are connected to the injection pipe fitting 301. Under the pressure of the external pump, the required clean water and chemicals are pressurized and injected into the inner tube 101. The clean water and chemicals are collectively referred to as raw materials. After the raw materials are mixed in the storage barrel 1, they wait for the wheat seed supervision system control device to operate, thereby constituting a spraying treatment for the wheat in the wheat planting area to prevent spring cold.

[0036] A sensor group 501 is arranged on the top of the meteorological telescopic frame 5, and a temperature sensor, a meteorological sensor and a high-definition industrial camera are arranged inside the sensor group 501. The temperature sensor is used to collect the ambient temperature value of the wheat planting area, the meteorological sensor is used to collect the real-time environmental value of the wheat planting area, and the high-definition industrial camera is used to collect the sample ratio reference value of wheat in the wheat planting area. The collected data ambient temperature value, real-time environmental value and sample ratio reference value are communicated by the control panel to the database of the planting general control center, forming a wheat seed supervision system.

[0037] During the startup of the device, the meteorological telescopic frame 5 drives the sensor group 501 to rise to a certain height, so that the sensor group 501 can monitor and process the wheat field within a certain range, and is used to control the environment of the wheat planting area and the wheat growth status for real-time monitoring. The device is distributed in advance according to the size of the wheat planting area, so as to cover the wheat planting area to be monitored in real time according to the four-axis direction and the allowable range of investment funds;

[0038] Among them, the temperature sensor is used to collect the ambient temperature value of the wheat planting area, the meteorological sensor is used to collect the real-time environmental value of the wheat planting area, and the high-definition industrial camera is used to collect the sample ratio reference value of wheat in the wheat planting area. The data ambient temperature value, real-time environmental value and sample ratio reference value are marked as Wz, Hz and Yz respectively. The control panel sends the collected data ambient temperature value Wz, real-time environmental value Hz and sample ratio reference value Yz to the database of the planting control center through communication.

[0039] The database obtains the preset temperature change range value threshold, preset environment value threshold and preset sample ratio threshold that are entered and stored, and compares and analyzes the data environment temperature value Wz, the real-time environment value Hz and the sample ratio reference value Yz.

[0040] A rectangular coordinate system is constructed with time as the X-axis and temperature as the Y-axis, and the data environment temperature value Wz is plotted on the rectangular coordinate system in a dotted manner according to the acquisition time, and the maximum and minimum values ​​of the preset temperature change range value threshold are plotted on the rectangular coordinate system in a dotted manner according to the time process, and the plotted points of the data environment temperature value Wz and the maximum and minimum values ​​of the preset temperature change range value threshold are connected with separate lines;

[0041] like Fig.10 As shown, the maximum and minimum values ​​of the preset temperature change range threshold are marked as A and C respectively, the data environment temperature value Wz is marked as B, and the data environment temperature value Wz that is lower than the minimum value of the preset temperature change range threshold is marked as D. If the data environment temperature value Wz gradually becomes lower than the minimum value of the preset temperature change range threshold along the time trend, a low temperature signal is generated and sent to the database.

[0042] The local weather data of the planting landmark is obtained through the database and Internet connection, and is comprehensively analyzed with the real-time environmental value Hz and the preset environmental value threshold. When the real-time environmental value Hz and the local weather data are both lower than the preset environmental value threshold, a meteorological anomaly signal is generated and sent to the database.

[0043] By comparing the sample ratio reference value Yz with the preset sample ratio threshold from the database, when the sample ratio reference value Yz is less than or equal to the preset sample ratio threshold, a protection signal is generated and sent to the database.

[0044] When the database receives the low temperature signal, the abnormal weather signal and the protection signal, it immediately generates text in the format of "late spring cold warning / estimated time 15H / plan activation" and displays it on the display screen in the main control room. At the same time, it generates a control signal, and the database feeds the control signal back to the control panel, which activates the electrical components in the spraying device.

[0045] Embodiment 2: This embodiment is an intelligent spraying device based on chemical prevention and control of late spring frost of wheat, including a meteorological telescopic frame 5 arranged at the top center of the cone disk 3, a material injection frame 6 arranged at the periphery of the meteorological telescopic frame 5, and a plurality of groups of unmanned landing platforms 4 arranged at the top edge of the cone disk 3.

[0047] The central stirring paddle 103 and the auxiliary paddle 104 rotate synchronously to mix and stir the poured raw materials. The raw materials in the inner cylinder 101 are initially mixed under the rotating stirring of the central stirring paddle 103, and are affected by the blade angle and rotation direction of the central stirring paddle 103, so that the raw materials in the inner cylinder 101 are pressurized and pushed downward, and then the raw materials in the inner cylinder 101 are pressurized along the overflow port 108 and enter the outer return chamber.

During this period, the telescopic cylinder 106 drives the limiting cone ring 102 to slide down along the inner wall of the top of the inner tube 101, causing the overflow port 108 between the inner tube 101 and the outer return chamber to open, and during the surging process of the raw materials pushed and increased in the outer return chamber, part of the raw materials close to the overflow port 108 flow back into the inner tube 101, forming a circulating mixing process, thereby preparing a mixed liquid.

After being collected by the exhaust pipe 302, it is circulated into the external return cavity with the assistance of the vacuum pump to form an air circulation pipeline, and the existing pipeline connection methods, such as flange connection, clamp connection and socket connection, are used between the air circulation pipelines.
