Description

Technical Field

[0001] The present invention relates to the technical field of fruit tree seedling cultivation, and in particular to a cultivation device and method for fruit tree seedling cultivation. Background Art

[0002] Fruit tree seedling cultivation is a key link in fruit tree cultivation. The quality of seedling cultivation directly affects the growth, yield and quality of fruit trees. The main technical points include: site selection and seedling selection; growth requires fertile soil and good drainage, and the seedlings must be straight, thick, with developed root systems and no scars; watering should be done regularly according to the growth of the seedlings and light intensity; in addition, it is also necessary to ensure that the fruit tree seedlings have sufficient light time, apply fertilizer regularly, and prune and prevent diseases and pests.

[0003] During the cultivation process of fruit tree seedlings, in addition to regular fertilization, pruning and disease and pest prevention, the most frequent maintenance is watering and ensuring light intensity. Among them, too little watering will affect the growth of fruit tree seedlings, and excessive watering will cause water accumulation and rot at the roots of fruit tree seedlings; and while ensuring sufficient light for fruit tree seedlings, it is also necessary to prevent the leaves from being sunburned by high light intensity.

[0004] At present, in the process of cultivating fruit tree seedlings, if they are placed in a single layer or in multiple layers with a large height difference, a large space will be required. If the height difference between each layer is small, as the fruit tree seedlings grow, their growth space will become smaller and smaller, and the effect of their lighting will be affected. In addition, it is difficult to carry out quantitative watering and shading treatment in time according to the growth of the fruit tree seedlings and the light intensity. Not only is the operation more cumbersome, but it is also not conducive to the growth of the fruit tree seedlings. Summary of the Invention

[0035] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0036] In the description of the present invention, it should be understood that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore should not be understood as limiting the present invention.

[0037] Example 1:

[0038] Reference Figures 1-8A cultivation device for raising fruit tree seedlings includes a seedling rack 1, and also includes: a lifting frame 3, which is arranged on the seedling rack 1, a lifting mechanism is provided between the seedling rack 1 and the lifting frame 3, for driving the lifting frame 3 to move upward along the seedling rack 1, and a hydraulic component 8 and a compression component 9 are provided between the lifting frame 3 and the seedling rack 1; an adjusting frame 12, the bottom end of which is symmetrically hinged to the seedling rack 1 through a hinge, and the end of the adjusting frame 12 away from the seedling rack 1 is slidably connected to the extension rod 13, a distance adjustment mechanism is provided between the two groups of adjusting frames 12, and a tray 17 is provided on the distance adjustment mechanism for adjusting the height difference between each tray 17; a bearing seat 18, which is symmetrically fixedly connected to the side of the seedling rack 1 away from the lifting frame 3, A rotating shaft 19 is rotatably connected to the bearing seat 18, and a shading net roller 20 is fixedly connected to the rotating shaft 19. A light control component is arranged between the side of the bearing seat 18 away from the shading net roller 20 and the rotating shaft 19, which is used to adjust the shading rate of the shading net; a sealed water tank 32 is fixedly connected to the seedling rack 1, and a water replenishment component is arranged between the sealed water tank 32 and the tray 17, which is used to replenish water for the fruit seedlings on the tray 17; a photovoltaic photosensitive element 39 and a visual sensor 40 are respectively fixedly connected to the adjusting frame 12 and the lifting frame 3, and are used to detect the light intensity and the growth status of the fruit seedlings, respectively. A plurality of walking wheels 41 are provided at the bottom of the seedling rack 1, which are used to move the seedling rack 1 to a designated position.

[0039] In this embodiment, after the cultivation tray loaded with fruit saplings is evenly placed on the tray 17, the growth of the fruit saplings is detected by the visual sensor 40, and the height difference between the fruit saplings at different levels is timely adjusted by the lifting mechanism and the distance adjustment mechanism, so as to ensure the growth space of the fruit saplings while reducing the space they occupy; in addition, the compression member 9 and the water replenishment component can be used to water the fruit saplings in time according to their growth conditions; further, when the light intensity is large, the photovoltaic photosensitive element 39 and the light control component are used to shade the fruit saplings. It should be explained that since the fruit saplings under different growth conditions have different acceptance levels of light intensity (generally, the larger the fruit saplings are, the greater the light intensity they can accept), that is, the fruit saplings under different growth conditions have different acceptance levels of light intensity. The shading rate required by the seedlings is different. Combined with the expansion and contraction of the compression member 9, the shading rate of the fruit seedlings is adjusted in time to ensure that the fruit seedlings can get sufficient light while avoiding damage to the leaves. According to the light intensity, the fruit seedlings are replenished with water in time in the evening to ensure the stable growth of the fruit seedlings. Among them, the visual sensor 40 and the photovoltaic photosensitive element 39 are conventional means in the existing technology, so they are not described in detail. The visual sensor 40 can detect the growth height range of the fruit seedlings. That is to say, when the fruit seedlings grow to a certain height, the stepper motor 7 is triggered by the visual sensor 40. The photovoltaic photosensitive element 39 can not only detect the light intensity, but also use photovoltaic power generation to provide power for the stepper motor 7, the solenoid valve 38, and the drive motor 28, which is more energy-saving and environmentally friendly.

[0040] Reference Figure 1-Figure 3 The lifting mechanism includes a storage cavity 2 provided on the seedling rack 1, a lifting frame 3 is slidably connected to the inside of the storage cavity 2, a positioning hole 4 is provided on the side of the seedling rack 1 close to the lifting frame 3, and a fixed rack 5 is fixedly connected to the side of the lifting frame 3 close to the positioning hole 4. A driving gear 6 that meshes with the fixed rack 5 is rotatably connected to the seedling rack 1, and a stepping motor 7 connected to the driving gear 6 is fixedly connected to the seedling rack 1, wherein the stepping motor 7 is electrically connected to the visual sensor 40. When the visual sensor 40 detects that the height of the fruit tree seedlings increases, the driving gear 6 is driven to rotate by the stepping motor 7, and the lifting frame 3 is driven to move upward along the seedling rack 1.

[0041] In this embodiment, when the fruit tree seedlings grow to a certain height, the stepper motor 7 is triggered by the visual sensor 40, driving the drive gear 6 to rotate, and under the action of the fixed rack 5, the lifting frame 3 is driven to move upward along the seedling rack 1, adjusting the overall height of the seedling rack 1 to ensure that the fruit tree seedlings have sufficient growth space and will not affect the photosynthesis of other fruit tree seedlings. At the same time, it can also reduce the space occupied by the fruit tree seedlings when they are small.

[0042] Reference Figure 3 and Figure 8 The inside of the hydraulic component 8 and the compression component 9 are both slidably connected with a piston 10. The side of the piston 10 away from the seedling rack 1 is fixedly connected to a support rod 11 that is slidably connected to the hydraulic component 8 or the compression component 9. The support rod 11 is connected to the lifting frame 3. The piston 10 separates the hydraulic component 8 and the compression component 9 into two groups of sealed chambers. An air intake pipe 33 is connected between the compression component 9 and the top of the sealed water tank 32. When the piston 10 moves upward along the compression component 9, the end of the air intake pipe 33 is connected to the sealed chamber in a compressed state.

[0043] In this embodiment, it needs to be explained that the sealed cavity above the hydraulic component 8 contains hydraulic oil, and the sealed cavity below is connected to the external environment to ensure the stability of the movement of the piston 10. When the piston 10 in the compression component 9 moves upward, it compresses the sealed cavity above, so that the gas inside it enters the sealed water tank 32 through the air inlet pipe 33, thereby increasing the pressure in the sealed water tank 32, so as to facilitate the subsequent squeezing out of the water in the sealed water tank 32, and the water discharge amount can be controlled according to the movement amount of the piston 10.

[0044] Reference Figure 4 and Figure 5The distance adjustment mechanism includes a slide groove 14 opened on the side where the adjustment frame 12 is close to each other. The slide groove 14 is slidably connected to multiple groups of sliders 15. Hydraulic rods 16 are fixedly connected between adjacent sliders 15. The tray 17 is rotatably connected between the sliders 15. The hydraulic rod 16 is connected to the hydraulic component 8 through a pipeline, and when the piston 10 moves upward along the hydraulic component 8, the end of the pipeline is connected to the sealed cavity in a compressed state. The end of the extension rod 13 away from the adjustment frame 12 is hinged to the lifting frame 3 through a hinge.

[0045] In this embodiment, it needs to be explained that when the cultivation pot is placed on the tray 17, the center of gravity of the entire tray 17 is located below the rotation position of the slider 15, that is, during the adjustment of the angle of the adjustment frame 12, the tray 17 is always in a horizontal state. When the lifting frame 3 moves upward, it will drive the piston 10 in the hydraulic part 8 to move upward, compress the sealed cavity above, and transport the hydraulic oil to the hydraulic rod 16. During this process, the position of the bottom tray 17 remains unchanged, and the distance between the upper trays 17 increases synchronously, thereby increasing the growth space of the fruit seedlings according to their height. While ensuring that the fruit seedlings have sufficient growth space, the space they occupy can be reduced.

[0046] Reference Figure 1 、 Figure 2 、 Figure 6 and Figure 7 The light control component includes a mounting plate 21 fixedly connected to the end of the rotating shaft 19, and the side of the mounting plate 21 away from the rotating shaft 19 is fixedly connected to the adjusting cylinder 22, and the rotating shaft 19 is slidably connected to a permanent magnet plate 23 connected to the telescopic end of the adjusting cylinder 22, and an elastic pull rope 24 sleeved on the rotating shaft 19 is fixedly connected between the permanent magnet plate 23 and the bearing seat 18, and the side of the mounting plate 21 close to the permanent magnet plate 23 is fixedly connected to an electromagnetic ring 25, wherein the adjusting cylinder 22 and the sealed cavity of the compression member 9 away from the air intake pipe 33 are connected through a pipeline and a slip ring, and when the piston 10 moves upward along the compression member 9, the adjusting cylinder 22 is in a contracted state, and the electromagnetic ring 25 is electrically connected to the photovoltaic light-sensing element 39. When the light intensity reaches a threshold value, the electromagnetic ring 25 is energized, and the greater the light intensity, the greater the magnetism of the electromagnetic ring 25, and the magnetic pole is the same as the magnetic pole on the side close to the permanent magnet plate 23.

[0047] In this embodiment, after the shading net is unfolded, the elastic pull rope 24 is in a stretched state. If the light intensity is too large, the electromagnetic ring 25 is energized to drive the permanent magnet plate 23 to move toward the side of the elastic pull rope 24 to shorten the distance between the permanent magnet plate 23 and the bearing seat 18. At this time, the elasticity of the elastic pull rope 24 is reduced, thereby increasing the shading effect of the shading net. At the same time, if the size of the fruit tree seedlings is larger at this time, that is, the fruit tree seedlings have a higher acceptance of light intensity, the position of the permanent magnet plate 23 is adjusted by adjusting the cylinder 22, that is, the elastic force of the elastic pull rope 24 is adjusted in combination with the size of the fruit tree seedlings and the light intensity, thereby adjusting the shading rate of the shading net. While ensuring that the fruit tree seedlings can get sufficient light, damage to the leaves can be avoided, which is more conducive to the growth of the fruit tree seedlings.

[0048] Reference Figure 1-Figure 2 , and also includes a driving motor 28 fixedly connected to the lifting frame 3, a winding roller 29 connected to the driving motor 28 is rotatably connected to the lifting frame 3, a connecting rope 30 connected to the shading net on the shading net roller 20 is sleeved on the winding roller 29, and a control switch 31 is provided on the winding roller 29, and the control switch 31 and the photovoltaic photosensitive element 39 are electrically connected to the driving motor 28.

[0049] In this embodiment, it needs to be explained that the shading net is a black mesh structure and has a certain elasticity. When the elastic force of the shading net is large, the size of the mesh is larger, that is, the shading rate is smaller. This is a conventional means in the prior art, so it is not described in detail. In the initial state, the shading net is rolled up on the shading net roller 20, and the connecting rope 30 will not affect the photosynthesis of the fruit tree seedlings. When the light intensity is large, the drive motor 28 is triggered to drive the winding roller 29 to rotate, and the shading net is driven to move to the side of the winding roller 29 through the connecting rope 30 until the shading net is rolled up on the winding roller 29. Then the control switch 31 is triggered to turn off the drive motor 28, completing the shading treatment of the fruit tree seedlings and preventing the fruit tree seedlings from being damaged by high-intensity light.

[0050] Reference Figure 2 、 Figure 4 and Figure 7The water replenishment component includes a fixing frame 35 fixedly connected to the tray 17, and a connecting piece 36 is fixedly connected to the side of the fixing frame 35 away from the tray 17. A plurality of groups of nozzles 37 connected to the connecting piece 36 are fixedly connected to the side of the fixing frame 35 close to the tray 17. A water supply pipe 34 is connected between the connecting piece 36 and the lower side wall of the sealed water tank 32, and an electromagnetic valve 38 is provided on the water supply pipe 34, wherein the end of the nozzle 37 is located above the fruit tree seedling tray, and the electromagnetic valve 38 is electrically connected to the photovoltaic photosensitive element 39. It also includes a compression cylinder 26 fixedly connected to the side of the bearing seat 18 close to the permanent magnet plate 23, and a spring 27 is fixedly connected to the inside of the compression cylinder 26, wherein the end of the compression cylinder 26 is in contact with the permanent magnet plate 23, and the exhaust end of the compression cylinder 26 is connected to the air intake pipe 33 through a pipeline, and the air intake end of the compression cylinder 26 is connected to the outside world.

[0051] In this embodiment, when the height of the lifting frame 3 is adjusted, the piston 10 in the compression member 9 is driven upward by the support rod 11 to transport the compressed gas into the sealed water tank 32. In addition, when the fruit tree seedlings are shaded, the movement of the permanent magnet plate 23 will squeeze the compression cylinder 26 and transport the gas in the compression cylinder 26 to the sealed water tank 32, so that the sealed water tank 32 is in a high-pressure state. In the evening, when the light intensity is low, the solenoid valve 38 is opened at this time, so that the water in the sealed water tank 32 is sprayed into the cultivation basin through the water supply pipe 34, the connecting piece 36 and the nozzle 37 to replenish the water of the fruit tree seedlings. In other words, based on the growth status of the fruit tree seedlings and the light intensity, the fruit tree seedlings can be watered in time to maintain the moisture of the soil, which is conducive to the growth of the fruit trees. It is very suitable for use in late spring, summer and early autumn to prevent the fruit tree seedlings from wilting due to lack of water under high temperature conditions.

[0052] Example 2:

[0053] Basically the same as Example 1, a cultivation method for fruit tree seedlings is proposed on the basis of Example 1, comprising the following steps:

[0054] Step 1: Place the seedling pots containing fruit tree seedlings evenly at different levels of the equipment;

[0055] Step 2: As the height of the fruit tree seedlings increases, the height difference between each layer of fruit tree seedlings is automatically adjusted;

[0056] Step 3: When the light intensity of the fruit tree seedlings is high, the fruit tree seedlings are shaded, and the shading rate of the fruit tree seedlings is automatically adjusted according to the growth of the fruit tree seedlings and the light intensity;

[0057] Step 4: In the evening, when the light intensity is low, add water to the fruit tree seedlings in a quantitative manner according to their growth and the light intensity of the day.
