Description

Technical Field

[0001] The invention relates to the technical field of agricultural machinery, and in particular to an induction type solar energy fruit tree frost and rain protection device and method. Background Art

[0002] During the fruit ripening and picking process, in addition to daily shaping and pruning, pest and disease control, and water and fertilizer management, the fruit must also be protected after setting in order to improve the internal and external quality of the fruit and increase profits.

[0003] For example, in early spring from March to April, the fruit trees are susceptible to low temperature frost damage due to the cold air, which damages the sprouting buds, flowers, and even young fruits and leaves, affecting the yield of the fruit trees and even leading to a complete failure of production. During the color change period of the fruit, it is necessary to avoid rain to prevent cracking of the fruit. For example, sweet cherries grown in the open field are prone to cracking of the fruit skin when they encounter too much rainfall or too much single rainfall during the color change period, thereby losing their commercial value. In addition, in the prior art, it is usually necessary to use a sunshade net in July and August to prevent abnormal flower bud differentiation. At this time, it is the flower bud differentiation period of cherry. Many varieties of flower buds encounter high temperature exposure, which will form double pistils or multiple pistils, and form twin fruits or conjoined deformed fruits after fruit setting in the second year. During the fruit ripening period, if there is a sudden rain, it is impossible to cover the film in time to prevent rain, resulting in the fruit trees and fruits being exposed to rain, which may cause a large amount of losses.

[0004] Although polyethylene film and other materials are used for long-term covering, they can effectively avoid rain, but they will also affect the light transmittance, thereby interfering with the photosynthesis of fruit trees. In the prior art, artificial film protection is usually carried out before the cold snap or rain occurs, and sunshade nets are used for sun protection in summer, which increases the work intensity of workers. Therefore, the present invention provides an induction solar fruit tree frost and rain protection device, which has the characteristics of flexible adjustment and is suitable for changes in different weather to ensure the normal development of fruits, improve fruit quality and normal differentiation of flower buds.

[0040] The following is further described in detail through specific implementation methods:

[0041] Embodiment 1:

[0042] As attached Figures 1 to 7As shown: an induction type solar frost and rain protection device for fruit trees, comprising a fixing frame 1, the fixing frame 1 comprising a first support rod 11 and a second support rod 12, the first support rod 11 is a telescopic rod, and the second support rod 12 is hinged to the top of the first support rod 11; a support frame for installing a sunshade net (not shown in the figure) and a shed film (not shown in the figure) is provided on the fixing frame 1; the support frame comprises a plurality of center rods 2 and inclined rods 21, the center rod 2 is located at the center of the second support rod 12, the inclined rods 21 are symmetrically arranged with the center rod 2 as the center, and the end of the inclined rod 21 away from the center rod 2 is lower than the end of the inclined rod 21 close to the center rod 2; the center rod 2 is located above the second support rod 12, the inclined rod 21 is vertically welded to the center rod 2, and a plurality of connecting rods 23 are welded between the inclined rod 21 and the second support rod 12.

[0043] The sunshade net is detachably connected to the top of the tilting rod 21 (not shown in the figure). In the present embodiment, a support rod (not shown in the figure) is welded to the top of the tilting rod 21, and the sunshade net is sleeved on the support rod; a roller mechanism for laying the greenhouse film is rotatably matched on the tilting rod 21, and the roller mechanism is located below the sunshade net; the roller mechanism includes a roller 3, a rotating shaft 31 is clamped at the center of the roller 3, and rollers are respectively clamped at both ends of the rotating shaft 31; a slide groove 22 runs through the tilting rod 21, the roller is located in the slide groove 22, and the roller and the slide groove 22 are clearance-matched; one end of the greenhouse film is bonded to the center rod 2, and the other end of the greenhouse film is bonded to the roller 3.

[0044] Release mechanisms for detecting the amount of rainfall are provided at both ends of the roller mechanism, and the release mechanisms are used to control the roller mechanism to lay the greenhouse film based on the rainfall; the release mechanism includes a first collecting trough 4 and a second collecting trough 41, and the first collecting trough 4 is located between adjacent inclined rods 21, and the first collecting trough 4 is located above the center rod 2, and extension plates are welded on both sides of the first collecting trough 4, and the end of the extension plate away from the first collecting trough 4 is located directly above the center rod 2; a floating block 44 is slidably fitted in the second collecting trough 41, and the end of the rotating shaft 31 away from the roller 3 passes through the slide groove 22, and the rotating shaft 31 is located above the floating block 44.

[0045] The second collecting groove 41 is also connected to the matching grooves 43 on both sides, and the floating block 44 is located below the matching groove 43. The side of the floating block 44 close to the matching groove 43 is lower than the side of the floating block 44 away from the matching groove 43. The matching groove 43 is connected to the slide groove 22, and the height of the matching groove 43 is smaller than the height of the slide groove 22, and the diameter of the rotating shaft 31 is smaller than the height of the slide groove 22.

[0046] It also includes a solar power generation component 5 located between the tilt rod 21 and the second support rod 12, one side of the solar power generation component 5 is welded to the center rod 2 through a bracket, and the other side of the solar power generation component 5 is bolted and fixed to the connecting rod 23; the solar power generation component 5 is electrically connected to a control panel for controlling the power generation power of the solar power generation component 5, and the solar power generation component 5 also includes a battery module for storing power.

[0047] The specific implementation process is as follows:

[0048] First, the fixing frame 1 and the supporting frame are installed according to seasonal needs, and the first supporting rod 11 and the second supporting rod 12 are used to form a basic supporting plane to provide a stable platform for the installation of the inclined rod 21 and the center rod 2; at the same time, the first supporting rod 11 is used to facilitate the adjustment of the overall supporting height of the supporting frame to adapt to the installation needs of different fruit tree heights, thereby ensuring the applicability of the device.

[0049] Before the fruits ripen, a roller mechanism is installed, and the greenhouse film is wound around the roller 3 to reduce the space occupied by the greenhouse film when not in use, so that it can be disassembled when not in use for easy recycling. During the laying process of the greenhouse film, since the end of the inclined rod 21 close to the center rod 2 is higher than the end of the inclined rod 21 away from the center rod 2, the natural gravity of the roller 3 is used to push the roller on the rotating shaft 31 to rotate in the slide 22, so as to automatically realize the laying process of the greenhouse film.

[0050] In the initial state of sunny weather, since the floating block 44 is located below the matching groove 43, the rotating shaft 31 is staggered with the matching groove 43 to keep the rotating shaft 31 fixed; in case of sudden rain, the first collecting groove 4 and the second collecting groove 41 are used to collect rainwater, and the extension plate is used to increase the rainwater receiving area to facilitate the collection and treatment of rainwater; while providing shielding for the solar power generation component 5, since the height of the center of the tilting rod 21 is higher than the height of the two sides of the tilting rod 21, when the outside wind enters under the greenhouse film, a pressure relief space is provided to reduce the continuous disturbance of the airflow on the greenhouse film. The rainwater is gathered inside the second collecting groove 41, and the buoyancy of the floating block 44 is used to lift the rotating shaft 31. When the rotating shaft 31 is aligned with the matching groove 43, the tilted floating block 44 is used to make the rotating shaft 31 slide out of the matching groove 43, and the rotating shaft 31 slides in the slide groove 22 through the roller to lay the greenhouse film to shield the fruit trees.

[0051] When it rains suddenly in summer, since the roller mechanism is located below the sunshade net, after the sunshade net and the greenhouse film (the greenhouse film and the sunshade net will not be used at the same time) are soaked by rain, the surface of the greenhouse film is easily adhered by the rain and sticks to the surface of the sunshade net, which can reduce the probability of the greenhouse film being moved and damaged by wind on rainy days, and also facilitate the formation of an inclined surface of the greenhouse film, reducing the continuous accumulation of rainwater in the center of the greenhouse film to form a collapse, thereby reducing the risk of damage to the greenhouse film and facilitating the discharge of rainwater above the greenhouse film.

[0052] Embodiment 2:

[0053] The difference from Example 1 is that a diverter block 42 is welded at the center of the second collecting tank 41, the height of the center of the diverter block 42 is higher than the side of the diverter block 42 close to the matching tank 43, and the two ends of the first collecting tank 4 are respectively located above the center of the diverter block 42.

[0054] The specific implementation process is as follows: on rainy days, when the water flow inside the first collection tank 4 converges and discharges into the second collection tank 41, the diverter block 42 is used to divide the water flow so that the water flow gathered on both sides of the diverter block 42 can quickly raise the height of the floating block 44 and timely release the fixed restriction of the rotating roller.

[0055] Embodiment 3:

[0056] The difference from Example 2 is that the guide plates 6 are rotationally matched between adjacent connecting rods 23 , both ends of the guide plates 6 are rotationally matched with the adjacent connecting rods 23 , and the guide plates 6 are parallel to the tilting rods 21 .

[0057] The specific implementation process is as follows: after laying the greenhouse film, in strong wind weather, the greenhouse film is easily separated from the sunshade net. In the process of the greenhouse film moving with the wind, it is very easy to be partially damaged by the strong wind; since the sunshade net is located above the greenhouse film, the guide plate 6 is facing the greenhouse film. When the outside wind passes through the guide plate 6, the wind is guided to blow toward the greenhouse film, so as to press the greenhouse film to fit the surface of the sunshade net, thereby facilitating the adhesion and fixation of the greenhouse film and the sunshade net.

[0058] Embodiment 4:

[0059] The difference from Example 3 is that the first support rod 11 is an electric push rod, which is electrically connected to the control panel and the solar power generation assembly 5; the control panel is used to obtain the power generation of the solar power generation assembly 5, and at the same time record the positional relationship between each first support rod 11 and the solar power generation assembly 5, the positional relationship including the first support rod 11 and the solar power generation assembly 5 with the same lateral mark and the first support rod 11 and the solar power generation assembly 5 with the opposite lateral mark; based on the power generation of the solar power generation assembly 5, the power generation is compared with the set first standard value. If the power generation is greater than the first standard value, the difference is calculated based on the power generation of the solar power generation assembly with the opposite lateral mark, and the difference is compared with the set second standard value. If the difference is greater than the second standard value, a descending command is sent to the first support rod 11 with the same lateral mark; if the difference is less than the second standard value, a maintenance command is sent to the first support rod 11 with the same lateral mark; if the power generation is less than the standard value, a maintenance command is sent to the first support rod 11 with the same lateral mark.

[0060] For example, in hot and sunny weather in summer, the first support rod 11 is raised and lowered to ensure the vertical irradiation area of ​​the solar power generation component 5 and the sunlight, so as to improve the utilization efficiency of the solar power generation component 5, facilitate the accumulation of electricity, provide night lighting energy, and improve resource utilization; at the same time, the irradiation direction of solar light at the current time is confirmed, so as to use the solar power generation component 5 to provide effective shielding, and reduce the impact of different irradiation directions on fruit trees in the morning or afternoon in summer.

[0061] Embodiment 5:

[0062] The difference from Example 4 is that both sides of the first collecting tank 4 are connected with heat dissipation pipes (not shown in the figure), and the heat dissipation pipes are located above the sunshade net.

[0063] The specific implementation process is as follows: the heat dissipation pipe facilitates the wetting of the water flow inside the first collection tank 4 and the sunshade net, so as to facilitate the adsorption effect when the subsequent greenhouse film and the sunshade net come into contact; in the hot summer, water is transported from the outside to the inside of the first collection tank 4 to wet the sunshade net through the heat dissipation pipe, so as to achieve environmental cooling and reduce the impact of high temperature on photosynthesis inside the fruit trees, so as to facilitate the normal growth and development of the fruit trees.

[0064] Embodiment 6:

[0065] The difference from Example 4 is that in this embodiment, according to the frost and rain protection method of the above-mentioned induction solar frost and rain protection device for fruit trees, in March and April, a greenhouse film is laid on the support frame to prevent frost. In another embodiment, a temperature sensor is bonded to the fixed frame 1, and the temperature sensor is electrically connected to a motor (not shown in the figure), the motor is coaxially connected to the rotating shaft 31, and the motor is slidably matched with the tilt rod; the temperature sensor is used to monitor the temperature value in real time, and send the temperature value to the control panel, the control panel is used to compare the temperature value with the set warning temperature value, when the temperature value is lower than the warning temperature value, start the motor to automatically unfold the greenhouse film, so as to realize the automatic unfolding of the plastic film under the temperature condition of low temperature frost damage; after May, a roller mechanism is used to shelter from rain, and the fruits of some fruit tree species and varieties begin to enter the color change period, and there is a risk of cracking. The device can be started at any time according to the weather conditions, and the greenhouse film is used to block and shelter from rain; under the natural light in July and August, for fruit trees that need shading, a sunshade net is laid on the support frame, and a roller mechanism and a first electric push rod are used for sun protection and rain protection.

[0066] Obviously, the above embodiments are merely examples for the purpose of clear explanation, and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived therefrom are still within the scope of protection of the invention.
