Description
Technical Field
[0001] The present application relates to the technical field of fruit planting, and in particular to an integrated spraying and frost prevention intelligent agricultural machine. Background Art
[0002] Fruits are rich in vitamins, minerals, dietary fiber and other nutrients, which have many benefits for human health and are consumed in large quantities in daily life. For example, vitamin C helps improve immunity, folic acid is essential for the health of pregnant women and fetuses, potassium helps maintain normal blood pressure, and some fruits also have special health functions, such as hawthorn helps lower blood pressure, kiwifruit is rich in antioxidants that can slow down aging, and blueberries help protect the eyes.
[0003] In recent years, in order to meet the growing consumer demand for fruits, the planting area of various fruit trees such as apples, kiwis, and grapes has increased rapidly. The cultivation of fruit trees usually has a certain period of time. During this planting period, the growth of fruit trees is greatly affected by the external environment temperature, especially the disaster weather. In particular, the late frost damage in spring every year is particularly serious. In some cases, the branches and leaves of fruit trees are damaged, and in some cases, all the branches, leaves, buds, and young fruits are frozen to death, resulting in serious production reduction or even total loss. For example, on April 24, 2002, the temperature in Yantai, Shandong Province dropped sharply to -4°C, causing apples, pears, grapes, peaches and other fruit trees to be severely frozen, with a total fruit loss of 5.2 billion yuan. Similarly, around April 8, 2018, the temperature in apple fruit areas such as the Northwest Loess Plateau, Gansu, and Shanxi dropped to -6.8°C, causing all the flowers and leaves of fruit trees to be frozen; kiwis in Meixian and Zhouzhi in Guanzhong, Shaanxi were frozen on a large scale, causing serious production reduction.
[0004] Frost also has a significant impact on the quality of fruits. Early spring frost may cause different degrees of damage to flowers, fruits and young branches and leaves, such as delayed flowering, abnormal development of stamens and pistils, curled leaves and dead tips, etc. If frost occurs in the young fruit stage, the damage is mild, leaving frost marks on the fruit surface. In severe cases, the young fruit stops expanding and becomes black and dead, which in turn causes direct economic losses to fruit farmers and the agricultural sector.
[0005] In order to reduce the impact of frost disasters on fruits, fruit farmers and agricultural departments need to take corresponding defensive measures, such as selecting varieties with strong frost resistance, watering orchards, artificial fumigation, spraying antifreeze and other comprehensive measures to prevent frost, etc. However, the above methods are still unable to effectively prevent and control late frost damage caused by extremely severe temperature drops and long duration, resulting in kiwifruit and other fruit trees still being affected by frost every year, causing direct economic losses. Summary of the invention
[0006] In response to the above-mentioned problems, the present application aims to provide an integrated intelligent agricultural machine for spraying and preventing frost. Before the arrival of frost and during the period when frost occurs, the machine can autonomously navigate the route through autonomous navigation planning in the fruit tree planting area, and spray hot smoke from burning gasoline at high speed through the smoke nozzle to fill the orchard, thereby promptly and effectively solving the impact of frost on fruits, avoiding fruit production reduction caused by frost, and ensuring the economic income of growers.
[0007] In order to achieve the above-mentioned purpose, the technical solution adopted in this application is as follows: an integrated spraying and anti-frost intelligent agricultural machinery, which includes a spraying body, and is characterized in that an anti-frost smoke spraying mechanism is arranged at the end of the spraying body in the moving direction, and an adjustable mechanism for extending the smoke residence time is also arranged between the smoke spraying mechanism and the spraying body.
[0008] Preferably, the smoke ejection mechanism is a smoke nozzle which is perpendicular to the travel direction of the sprayer body and symmetrically arranged on both sides of the end of the sprayer body.
[0009] Preferably, the smoke nozzle port is closed, and nozzles are provided on the outer peripheral surface near the port at circumferential intervals.
[0010] Preferably, the adjustable mechanism is to hinge the smoke nozzle along the travel direction of the sprayer body, and extend an air guide plate on the other side of the smoke nozzle at the hinge point.
[0011] Preferably, an arc structure is provided on the outer side of the air guide plate, and a cross section of the air guide plate is provided as an arc structure.
[0012] The beneficial effects of the present application are as follows: the integrated spraying and anti-frost intelligent agricultural machinery, on the basis of efficient spraying and plant protection, adds a new anti-frost function by integrating auxiliary components such as smoke nozzles on the spraying machine body. That is, after knowing in advance the weather forecast information of the impending late frost damage, gasoline is prepared in advance, the machinery is debugged, and the smoke spraying route planning is input for the intelligent agricultural machinery. Before and during the period of frost occurrence, the integrated spraying and anti-frost intelligent agricultural machinery can walk autonomously and continuously along the rows of fruit trees through a remote control handle or autonomous navigation, and continuously spray hot smoke from burning gasoline through the smoke nozzles on both sides of the end to fill the orchard, preventing the temperature in the orchard from dropping rapidly, and can timely and effectively alleviate the impact of frost on the branches and leaves, buds or young fruits of fruit trees, avoid frost-induced fruit production reduction or freezing of branches and leaves of fruit trees, and ensure the healthy growth of fruit trees and the economic income of growers.

[0023] In order to enable ordinary technicians in the field to better understand the technical solution of the present application, the technical solution of the present application is further described below in conjunction with the accompanying drawings and embodiments.
[0024] See attached Figures 1 to 8 An integrated spraying and anti-frost intelligent agricultural machine is shown, which includes a spraying machine body 1. The spraying machine body 1 is preferably a crawler structure, which is convenient for stable movement on an uneven surface. The movement is equipped with a navigation system such as GPS, and the travel route can be set in advance. The planned route can be traveled and sprayed in large fruit-growing areas, which greatly improves the efficiency and quality of fruit spraying.
[0025] In order to solve the problem of frost on fruits by using the operation mode of the spraying machine 1, Figure 2As shown, a frost-proof smoke ejection mechanism is provided at the end of the sprayer body 1 in the direction of travel. The smoke ejection mechanism ejects diffuse hot smoke in the orchard along with the travel drive of the sprayer body 1. The hot smoke itself has a high temperature and increases the temperature of the orchard. The smoke can also increase the concentration of carbon dioxide in the atmosphere. These carbon dioxide can strongly absorb the long-wave radiation of the ground, so that the atmosphere warms up and enhances the reverse radiation of the atmosphere, thereby playing a role in keeping the ground warm and preventing frost. Then, through the route planning and driving of the sprayer body 1, when the information of frost occurrence is known in advance through the weather forecast, during the frost occurrence period, the route planning of the sprayer body 1 allows the smoke ejection mechanism to spray smoke in the fruit tree planting area, thereby timely and effectively solving the problem of frost affecting the fruit. Through the self-propelled mode of the sprayer body 1 and the uninterrupted (non-stop during the frost period) smoke ejection during travel, frost can be effectively prevented, and the reduction of fruit production caused by frost can be avoided, thereby ensuring the economic income of growers.
[0026] During the above-mentioned smoke spraying time period, there may still be the influence of natural wind, which will blow the sprayed smoke away from the fruit tree area. Therefore, in order to solve this problem, an adjustable mechanism for extending the smoke residence time is also provided between the smoke spraying mechanism and the sprayer body 1. The adjustable mechanism drives the smoke spraying mechanism through the action of wind to resist the wind blowing, thereby reducing the influence of wind on the sprayed smoke, so that under the action of wind, the smoke can still stay in the fruit trees for a long time, thereby achieving the effect of resisting frost on the fruit.
[0027] Specifically, Figure 2-3 As shown, the smoke ejection mechanism is a smoke nozzle 2 which is perpendicular to the travel direction of the sprayer body 1 and symmetrically arranged on both sides of the end of the sprayer body 1. Specifically, a fuel tank and a cigarette lighter which are not shown are also integrated on the sprayer body 1. The fuel in the fuel tank is ignited by the cigarette lighter, and the smoke is ejected toward both sides of the sprayer body 1 through the smoke nozzle 2, just spraying to the bottom of the fruit trees in the adjacent rows. The smoke diffuses upward, covering the fruit trees and the fruits on them, thereby preventing the fruits from being damaged by frost. During the frost period, the sprayer body 1 continues to move in the fruit tree planting area and spray smoke, ensuring that the smoke stays for a long time, and providing complete protection during the entire frost period.
[0028] In order to further increase the smoke diffusion area, Figure 5 As shown, the end of the smoke nozzle 2 is closed, and a nozzle 2a is provided on the outer peripheral surface near the end along the circumferential spacing. That is, the smoke is sprayed circumferentially from the circumference of the smoke nozzle 2, and can be quickly dispersed in the spraying stage, thereby quickly covering and protecting the fruit trees and fruits.
[0029] like Figure 4As shown in the figure, when the wind blows in the direction of the arrow in the figure, the smoke is also blown away in this direction, and then in order to solve the blowing effect of the wind direction, as shown in the figure, Figure 6 As shown, the adjustable mechanism is to hinge the smoke nozzle 2 along the travel direction of the spraying machine body 1, and extend the wind guide plate 3 on the other side of the smoke nozzle 2 at the hinge point. The preferred wind guide plate 3 has a cross-sectional area larger than the smoke nozzle 2, and one side of the wind guide plate 3 is larger than the arm length of the smoke nozzle 2, so that after the wind force acts on the smoke nozzle 2 and the wind guide plate 3, the wind guide plate 3 can withstand a large wind force, and deflect toward the rear of the spraying machine body 1 by the wind force, thereby driving the smoke nozzle 2 to deflect in the direction of the wind against the wind with a hinged structure. After changing the position of the ejection port 2a, the ejected smoke can still extend its residence time in the fruit tree under the action of wind, solve the problem of rapid dispersion of smoke in the downwind state, and ensure the duration of smoke resistance to frost.
[0030] Under the above-mentioned wind force, since the smoke nozzle 2 and the wind guide plate 3 are simultaneously affected by the wind, the smoke nozzle 2 can be smoothly driven to deflect through the wind guide plate 3 and be in a position against the wind, such as Figure 7 As shown, an arc structure is provided on the outer side of the air guide plate 3, and the arc structure can facilitate the air volume to be collected on the air guide plate 3. With the collected air volume, the wind resistance of the smoke nozzle 2 is overcome, thereby facilitating the smooth deflection of the smoke nozzle 2 under the action of wind.
[0031] Further preferably, Figure 8 As shown, the cross section of the air guide plate 3 is set to an arc-shaped structure, which also further increases the collected air volume on the air guide plate 3, and further facilitates the upwind deflection of the smoke nozzle 2 under the action of wind force, so that the smoke overcomes the wind force and prolongs its residence time.
[0032] The principle of the present application is: the integrated spraying and anti-frost intelligent agricultural machine integrates the smoke nozzle 2 and other auxiliary components on the spraying machine body 1, and utilizes the route planning of the spraying machine body 1, so that the smoke ejection mechanism sprays hot smoke through the smoke nozzle 2 in the fruit tree planting area, thereby timely and effectively solving the problem of frost on the fruit. During the process of traveling, if there is wind force, after the wind force acts on the wind guide plate 3, the wind guide plate 3 can withstand the greater wind force, and deflect toward the rear of the spraying machine body 1 by the wind force, thereby driving the smoke nozzle 2 to deflect in the direction of the wind against the wind with a hinged structure. After changing the position of the ejection port 2a, the ejected smoke can still extend its residence time in the fruit tree under the action of wind force, solving the problem of rapid dispersal of smoke in the downwind state, and ensuring the duration of smoke resistance to frost.
[0033] By the self-propelled mode of the spraying machine body 1 and the uninterrupted (non-stop during the frost period) smoke spraying during movement, frost can be effectively prevented, the reduction of fruit production caused by frost can be avoided, and the economic income of growers can be guaranteed.
[0034] The above shows and describes the basic principles, main features and advantages of the present application. Without departing from the spirit and scope of the present application, the present application may have various changes and improvements, which fall within the scope of the present application to be protected.
