Description

Technical Field

[0001] The invention relates to the technical field of orchard anti-frost equipment, and in particular to a self-propelled orchard anti-frost device. Background Art

[0002] Frost, as a common agricultural meteorological disaster, has a significant impact on the growth and development of fruit trees and the quality of fruit yield. Especially in spring, the critical period for fruit trees to bloom and bear fruit, late frost can directly freeze the buds, shoots, flowers and young fruits of fruit trees, and in severe cases even cause the death of fruit trees.

[0003] Early anti-frost methods mainly include covering, fumigation, and irrigation. Although these methods have certain effects, they are inefficient and require a lot of manpower and material resources. With the advancement of science and technology, some orchard anti-frost devices have emerged. These devices mainly reduce the harm of frost by increasing local temperature, preventing cold air from settling, or promoting air flow. Common anti-frost devices include fans, fumigators, heaters, and sprinkler systems.

[0004] There are some defects and shortcomings in the existing technology for orchard frost prevention: the current frost prevention equipment has deficiencies in navigation and precise positioning, making it difficult to ensure that every corner of the orchard is fully protected; although temperature monitoring is the key to frost prevention, the existing system lacks high automation and good linkage with frost prevention equipment; traditional frost prevention methods such as fumigation and heating, although simple and easy, need to be improved in terms of efficiency and accuracy; some frost prevention methods may have adverse effects on the ecological environment, such as spraying chemical antifrost agents will pollute the soil and water sources. Summary of the invention

[0005] In view of the above-mentioned deficiencies in the prior art, the present invention provides a self-propelled orchard anti-frost device which solves the problems of insufficient positioning function, imperfect temperature monitoring and early warning system and low efficiency of the existing orchard anti-frost device.

[0006] In order to achieve the above-mentioned invention object, the technical solution adopted by the present invention is: a self-propelled orchard frost protection device, including a control system, a power supply device, a chassis and a heat source box connected to each other;

[0007] The chassis includes a Beidou navigation crawler-type driving chassis and a temperature monitoring and early warning device arranged on the Beidou navigation crawler-type driving chassis, and the temperature monitoring and early warning device is electrically connected to the control system;

[0008] The heat source box is arranged on the chassis, and comprises a protective cover for heat insulation, a heating device arranged in the protective cover, and a wind disturbance device;

[0009] The heating device comprises a furnace body arranged in a protective cover, a diesel burner is arranged inside the furnace body, an automatic ignition start device and a constant temperature power off device are arranged on the diesel burner, and both the automatic ignition start device and the constant temperature power off device are electrically connected to the control system; a hot air pipe is arranged on the side wall of the furnace body, and a heat dissipation chimney is arranged on the top of the furnace body;

[0010] The wind disturbance device comprises a high-pressure fan and an air outlet arranged on both sides of the heat source box.

[0011] The beneficial effects of the present invention are as follows: the device provides an efficient, intelligent and accurate anti-frost solution for orchards through Beidou navigation technology, automatic control system, efficient heating device and wind disturbance device. Among them, the Beidou navigation crawler drive chassis realizes the accurate positioning and path planning of the anti-frost device in the orchard. The Beidou navigation system has high-precision, all-weather and all-day positioning capabilities, ensuring that the anti-frost machine can operate autonomously according to the preset route, avoiding the errors and instability of manual operation, and improving the coverage and accuracy of orchard anti-frost. Especially in large orchards, it can ensure that every fruit tree can get timely anti-frost protection.

[0012] The high-precision automatic temperature monitoring and early warning device can monitor the temperature in the orchard in real time and send out early warning signals in time when the temperature drops to a preset threshold (such as 0 degrees Celsius). This not only improves the level of intelligent management of the orchard, but also provides timely and accurate information support for frost prevention operations. By monitoring the temperature in real time, the device can start the heating device in advance before frost occurs, thereby effectively preventing frost from harming the fruit trees.

[0013] As a heat source, the diesel burner has the advantages of high thermal efficiency, complete combustion and low emissions. The hot air pipe and wind disturbance device increase the heat transfer efficiency by increasing the heat dissipation area and optimizing the heat dissipation structure, so that the anti-frost machine outlet can continuously output stable high-temperature hot air, effectively improving the anti-frost effect.

[0014] The device is equipped with an automatic start device to achieve automatic operation. When the temperature monitoring and early warning device sends out an early warning signal, the automatic start device will immediately start the heating device and wind disturbance device without frequent manual intervention, which not only improves work efficiency but also reduces labor costs.

[0015] Through the double-sided fan design, the device can generate powerful wind disturbance, so that the hot air can be diffused more evenly in the orchard. It not only helps to transport the hot air to every corner of the orchard, but also effectively disturbs the cold air and prevents the formation of frost.

[0016] As the energy source of the entire system, the power supply device can meet the power requirements of various components of the anti-frost machine and ensure the stable operation of the equipment in the orchard. The battery life of this power supply device is 6-8 hours, which meets the anti-frost needs of the orchard during low temperature periods such as nighttime.

[0017] Furthermore, in the above-mentioned self-propelled orchard anti-frost device, the power supply device is a gasoline generator, and the gasoline generator is arranged on the chassis.

[0018] Furthermore, in the above-mentioned self-propelled orchard anti-frost device, a chimney heat dissipation pipe is arranged on the heat dissipation chimney.

[0019] The beneficial effect of adopting the above further scheme is that the chimney heat dissipation pipe can utilize the principles of heat radiation and convection heat dissipation to effectively increase the heat dissipation area, help to discharge the heat generated inside the device in time, prevent the equipment from overheating, and ensure that the anti-frost device can operate continuously and stably.

[0020] Furthermore, in the above-mentioned self-propelled orchard anti-frost device, heat pipes are arranged on both sides of the protective cover.

[0021] The beneficial effect of adopting the above further solution is that the heat pipe can transfer the heat generated inside the protective cover to the external environment more effectively.

[0022] Furthermore, the power of the gasoline generator of the above-mentioned self-propelled orchard anti-frost device is 3kW.

[0023] The beneficial effect of adopting the above further scheme is: using a 3kW gasoline generator to supply power can meet the power requirements of various components of the anti-frost machine and ensure the stable operation of the equipment in the orchard.

[0024] Furthermore, the power of the high-pressure fan of the above-mentioned self-propelled orchard anti-frost device is 0.25KW.

[0025] Furthermore, the length of the protective cover of the self-propelled orchard anti-frost device is 1.4m, the width of the protective cover is 1.2m, and the height of the protective cover is 1.0m.

[0026] Furthermore, the length of the furnace body of the self-propelled orchard anti-frost device is 1.2 m, the width of the furnace body is 1.0 m, and the height of the furnace body is 0.8 m.

[0027] Furthermore, the above-mentioned self-propelled orchard anti-frost device has a 3 cm thick heat insulation material on the protective cover.

[0028] The beneficial effects of the present invention are as follows: the device has the advantages of high efficiency, stability, reliability and energy saving, can quickly and effectively cover fruit trees to prevent the occurrence of frost; can run continuously for 5 hours to ensure the anti-frost effect at night; adopts Beidou navigation crawler drive, can adapt to the complex terrain of the orchard, and ensure the stability of the machine; adopts diesel burner and wind disturbance device, can achieve simultaneous air disturbance and air heating.

[0032] The specific implementation modes of the present invention are described below so that those skilled in the art can understand the present invention. However, it should be clear that the present invention is not limited to the scope of the specific implementation modes. For those of ordinary skill in the art, as long as various changes are within the spirit and scope of the present invention as defined and determined by the attached claims, these changes are obvious, and all inventions and creations utilizing the concept of the present invention are protected.

[0033] like Figures 1-2 As shown, this embodiment provides a self-propelled orchard anti-frost device, which has the characteristics of intelligence, automation and high efficiency, and is intended to improve the anti-frost ability of the orchard and ensure the normal growth of fruit trees. The device includes an interconnected control system, a power supply device, a chassis 1 and a heat source box 2, and the components are interconnected and work together to achieve the anti-frost function.

[0034] The control system is the brain of the entire device, responsible for receiving, processing and analyzing various signals, and issuing corresponding control instructions. In this embodiment, the control system adopts single-chip control technology, integrates functions such as temperature monitoring, early warning and automatic control, and exchanges data with the remote monitoring center through a wireless communication module. Through programming and setting, the control system can monitor the temperature of the orchard in real time, and automatically adjust the working state of the heating device according to the temperature change to achieve the purpose of frost prevention.

[0035] The power supply device provides power support for the entire device. Considering the complexity of the orchard environment and the mobility of the equipment, this embodiment uses a gasoline generator 6 as the power supply device. The gasoline generator 6 has the advantages of small size, light weight, high power, and easy mobility, and can meet the needs of long-term operation of the device in the orchard. The power of the gasoline generator 6 is 3kW, which ensures the normal operation of components such as the heating device, the control system, and the wind disturbance device.

[0036] The chassis 1 is the basic part of the device, which is responsible for supporting and fixing other components and realizing movement in the orchard. The present embodiment adopts the Beidou navigation crawler drive chassis 31, which has powerful off-road capability and stable navigation performance. A temperature monitoring and early warning device 4 is provided on the chassis 1, which is electrically connected to the control system and can monitor the temperature of the orchard in real time and transmit data to the control system. The chassis 1 is also made of high-strength, corrosion-resistant materials to ensure the long-term stable operation of the device in harsh environments.

[0037] The heat source box 2 is responsible for generating and providing heat to increase the temperature in the orchard. The heat source box 2 includes a protective cover 5, a heating device and a wind disturbance device.

[0038] The protective cover 5 is used to protect the heating device from interference and damage from the external environment. The protective cover 5 is made of high temperature resistant and corrosion resistant materials and has good thermal insulation and protection performance. The protective cover 5 is 1.4m long, 1.2m wide and 1.0m high, ensuring that the heating device has sufficient space and heat dissipation conditions.

[0039] The heating device is responsible for generating heat, and includes a furnace body 7 and a diesel burner 8. The furnace body 7 is made of high-quality steel, and a diesel burner 8 is arranged inside. The diesel burner 8 has the advantages of high combustion efficiency, high calorific value, good stability, etc., and can quickly generate a large amount of heat. The diesel burner 8 is provided with an automatic ignition start device and a constant temperature power-off device. Both devices are electrically connected to the control system, and can receive instructions from the control system and automatically start or shut down the diesel burner 8. A hot air pipe 9 is arranged on the side wall of the furnace body 7 for conveying the heated air into the orchard. A heat dissipation chimney 10 is arranged on the top of the furnace body 7 for discharging exhaust gas generated by combustion. In order to improve the heat dissipation effect, a chimney heat dissipation pipe is also arranged on the heat dissipation chimney 10.

[0040] The wind disturbance device is used to blow the heated air evenly into the orchard to improve the anti-frost effect. The wind disturbance device includes a high-pressure fan 11 and an air outlet 12. The high-pressure fan 11 is arranged on both sides of the heat source box 2 and can generate strong wind. The air outlet 12 is arranged below the heat source box 2 and is used to blow the heated air into the orchard. The power of the high-pressure fan 11 is 0.25KW, which can ensure the uniform distribution and effective circulation of air in the orchard.

[0041] In order to ensure the effective operation of the self-propelled orchard anti-frost device, this embodiment sets and adjusts the operating parameters of the device.

[0042] The operating speed is the speed at which the device moves in the orchard. In this embodiment, the operating speed is set to 1m / s. This speed can ensure that the anti-frost machine moves stably in the orchard and effectively covers the orchard. By adjusting the operating speed, uniform heating and anti-frost effects can be achieved in different areas of the orchard.

[0043] The temperature of the air outlet 12 is the temperature of the heated air when it is blown out from the air outlet 12. By adjusting the temperature of the air outlet 12, the temperature in the orchard can be accurately controlled and adjusted. In this embodiment, the temperature of the air outlet 12 is set to 80 degrees Celsius. At this temperature, the temperature around the fruit trees 3 meters away can reach 10°C-15°C, which can effectively increase the temperature in the orchard and prevent frost from damaging the fruit trees.

[0044] The battery life is the time that the power supply device can run continuously after a single refueling. In this embodiment, the battery life is set to 5 hours. This life meets the frost protection needs of the orchard during low temperature periods such as nighttime. By optimizing the working state of the power supply device and the control system, the endurance and stability of the device can be further improved.

[0045] The operation process of the self-propelled orchard anti-frost device needs to follow certain steps and processes to ensure that the device can work normally and play an anti-frost effect.

[0046] After starting the device, the temperature automatic monitoring and early warning system starts working, monitoring the temperature of the orchard in real time. Through sensors and control systems, the temperature data in the orchard can be obtained in real time, processed and analyzed.

[0047] When the temperature reaches 0 degrees Celsius, the early warning system sends a signal to the automatic starting device, which starts the diesel burner 8. This step is the key to the device being able to automatically respond to temperature changes and start the heating system.

[0048] The heating system starts working, the gasoline generator 6 supplies power to the entire device, and the high-pressure fans 11 on both sides start running, blowing the heated air out from the air outlets 12 on both sides. At the same time, the anti-frost device runs in the orchard at a speed of 1m / s according to the route set by the Beidou navigation, and continues to run for 5 hours or until the temperature returns to a safe range. During this process, the control system continuously monitors the temperature of the orchard and the working status of the device, and adjusts and controls it as needed.

[0049] Through the above-mentioned operation process, the self-propelled orchard anti-frost device can achieve effective anti-frost protection for the orchard and improve the yield and quality of the orchard.
