Description

Technical Field

[0001] The present invention relates to the technical field of plant cultivation, and specifically to a plant cultivation device with an automatic watering function. Background Art

[0002] Plant cultivation devices can cultivate and plant plants. Conventionally, soil cultivation is used, and a small number use soilless cultivation. However, soilless cultivation can only be applied to a small number of plants and cannot meet the needs of most plants. Soil cultivation requires regular watering of the plants to supplement the water required by the plants. When cultivating and planting seeds or seedlings, fertilizers are applied to the plants as needed to accelerate the growth of the plants and supplement the nutrients lacking during the growth of the plants. However, existing cultivation equipment cannot accurately add fertilizers and cannot add fertilizers quantitatively. If less fertilizer is applied, the effect will not be obvious, while if more fertilizer is applied, it will lead to nutrient excess, causing the plants to wither and turn yellow, and in severe cases, the plants will die. Summary of the Invention

[0003] The purpose of the present invention is to provide a plant cultivation device with an automatic watering function to solve the problems raised in the prior art.

The filtering component is installed above the drainage trough, and the filtering component can collect the cultivation soil and filter the excess liquid.

[0006] Further, the filtering component includes two sets of mounting frames, which are also inclined and mounted inside the recycling frame.

[0007] Further, the detection component includes multiple sets of induction wires and multiple sets of receiving blocks. The multiple sets of induction wires are equidistantly mounted inside the planting table, and the multiple sets of receiving blocks are equidistantly mounted on the induction wires. The induction wires are connected to the controller and cooperate with the spraying component.

[0008] Further, when the conductivity of the induction wire drops to the threshold value, the corresponding spray head will stop replenishing water.

[0009] When the conductivity of the induction wire meets the threshold value, the corresponding spray head will not stop replenishing water.

[0010] Further, the spraying component includes two sets of water storage tanks. Above one of the water storage tanks, a fertilizer adding component and a water pump are mounted. The output end of the water pump is mounted with a conduit, and the conduit is respectively matched with multiple sets of spraying components. The spraying component also includes a spraying plate. Multiple sets of spraying pipes are mounted inside the spraying plate, and multiple sets of spray heads are mounted at the bottom of the spraying plate. The spray heads are connected to the spraying pipes.

[0011] Further, the fertilizer adding component includes a tank body, which is connected to the water storage tank.

Water-soluble fertilizer is provided inside the tank body, and a storage amount monitoring component is mounted inside the tank body. The storage amount monitoring component can detect the total amount of water-soluble fertilizer in the current tank body.

[0012] Further, the storage amount monitoring component includes a detection tube. A detection spring and a detection plate are provided inside the detection tube. Multiple sets of limiting grooves are provided at the bottom of the detection tube. The detection spring can contract after being electrified.

[0016] 1. When the device is in use, it can automatically supplement water to the planted plants according to the humidity condition of the planted plants, and can also apply fertilizers during irrigation, thereby promoting the growth of the planted plants. Moreover, because the chemical fertilizer and water are quantitatively fused, over-fertilization of the plants can be prevented.

[0017] 2. When the detection component is in use, it can detect the current humidity of the planting table so as to irrigate the planting table according to the humidity to supplement the water of the planted plants. Specifically, when in use, the controller can energize the induction wire to control the induction wire to emit current to the receiving block. Since the external humidity will affect the conductivity, when the humidity in the planting table is in a normal state, the conductivity of the induction wire will be between the normal thresholds. When the humidity of the planting table is low, the conductivity of the induction wire will exceed the threshold at this time. When the humidity of the planting table is high, the conductivity of the induction wire will be lower than the threshold. Furthermore, the controller can automatically spray the planting table according to the detection component.

[0018] 3. When the fertilizer adding component is in use, it can quantitatively add water-soluble fertilizers according to the total amount of liquid in the water storage tank, so that the liquid in the water storage tank can be matched with an appropriate amount of water-soluble fertilizers, so as to irrigate the water-soluble fertilizers onto the planted plants while irrigating the planted plants. And mainly through the storage amount monitoring component, the storage amount of the water-soluble fertilizers can be monitored all the time, so that the amount of water-soluble fertilizers input each time can be known.

Specific embodiments

[0029] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0030] Embodiment: As Figures 1 - 9 shown, the present invention provides a technical solution for a plant planting device with an automatic watering function, including a main body 1 of the planting device and a controller 9. The main body 1 of the planting device includes a support frame 11, and a plurality of planting tables 12 are installed on the support frame 11. The planting tables 12 are sequentially installed between the support frames 11 from bottom to top. A detection component 2 is installed between each group of planting tables 12, a spraying component 3 is installed above each group of planting tables 12, a filter component 4 and a recycling component 5 are installed below each group of planting tables 12, and a separation component 6 is installed at the bottom of the lowermost planting table 12. The separation component 6 can separate the cultivation soil and the liquid;

[0031] When the device is in use, first, seeds or seedlings need to be planted in the planting table 12, and according to the specifications of the planting table 12, the seeds or seedlings should be evenly planted in the planting table 12. After that, the device can cultivate the seeds or seedlings. Specifically, during use, the detection component 2 can continuously detect the dryness and humidity of the entire planting table 12. When the detection component 2 detects that the planting table 12 is relatively dry, the controller 9 will control the spraying component 3 to irrigate the plants in the planting table 12 through the spraying component 3. When the spraying component 3 reduces the humidity in the planting table 12 to a specific threshold, the controller 9 will control the irrigation component to stop working. While the spraying component 3 is working, the staff can add water-soluble fertilizers according to the current condition of the plants. Thus, while the spraying component 3 is working, the water-soluble fertilizers are irrigated onto the plants together, thereby promoting the growth of the plants. After that, to ensure that the plants on the device can maintain a well-ventilated position, the device can separate each group of planting tables 12 after spraying, increasing the distance between two adjacent planting tables 12, so that air can flow more smoothly between the devices. At the same time, when the device needs to receive sunlight, it can also adjust the position of the planting table 12 according to the current situation, so that the plants on the planting table 12 can absorb sunlight more comprehensively. Therefore, when the device is in use, it can cultivate plants more fully.

[0032] As Figure 4 shown, in this embodiment, specifically, multiple groups of diversion pipes 111 are respectively installed on both sides of the support frame 11. One end of each group of diversion pipes 111 is matched with each recovery component 5, and the other end of the diversion pipes 111 is matched with the separation component 6. The recovery component 5 includes a recovery frame 51, which is installed at the bottom of the planting table 12. Discharge pipes 52 are respectively installed on both sides of the recovery frame 51, and the discharge pipes 52 are matched with the diversion pipes 111. A filtering component 4, a drainage groove 53 and a diversion plate are arranged inside the recovery frame 51. The drainage groove 53 is connected to the discharge pipe 52. The diversion plate is inclined and installed inside the recovery frame 51, and the height of the end of the diversion plate in contact with the drainage groove 53 is lower than the other end. The filtering component 4 is installed above the drainage groove 53, and the filtering component 4 can collect the culture soil and filter out the excess liquid;

[0033] The main function of the diversion pipes 111 on both sides of the support frame 11 is to collect the liquid discharged by the recycling component 5 uniformly, and then supply the uniformly collected liquid to the separation component 6 so that the separation component 6 can separate the solids in the liquid. The separated liquid will be returned to the separate water storage tank 31 for subsequent utilization of the recycled liquid, thereby reducing waste of resources. During specific use, since the planting table 12 of this device will only be adjusted after spraying to enable the plants to grow fully. And because the recycling component 5 is provided at the bottom of the planting table 12, when the planting table 12 is sprayed, some of the infiltrated liquid will enter the recycling component 5. At the same time, the filtering component 4 will filter the infiltrated liquid. Since some of the liquid will carry a small amount of cultivation soil and enter the recycling component 5 together, the liquid is initially filtered by the filtering component 4 to reduce the consumption of subsequent separation. During specific use, when the planting table 12 moves outwards and reaches a specific position, the discharge pipe 52 on the recycling frame 51 will cooperate with the diversion pipe 111 to collect the excess liquid uniformly, thus being able to save waste of resources.

[0034] As Figure 4 shown, in this embodiment, specifically, the filtering component 4 includes two sets of mounting frames 41. The mounting frames 41 are also inclined and installed inside the recycling frame 51. One end of the mounting frame 41 above the drainage groove 53 is higher than the other end. A diversion plate is also installed above the mounting frame 41. The two diversion plates are staggered in the horizontal direction. A filter membrane 42 is installed on the side of the mounting frame 41;

[0035] When the filtering component 4 of this device is in use, it can initially separate the cultivation soil and the liquid, discharge the liquid, and confine the cultivation soil within the recycling frame 51. After using this device for a specific period of time, the recycling frame 51 can be opened to recycle the cultivation soil uniformly for recycling and utilization. During specific use, since diversion plates are respectively provided at the bottom of the recycling frame 51 and above the filtering component 4, and the diversion plates are staggered in the horizontal direction, when any liquid drops above a diversion plate, the liquid will move by itself along the inclination of the diversion plate until the liquid flows into the drainage groove 53. Then, the liquid will be uniformly discharged through the drainage groove 53 so that the liquid can be uniformly collected through the diversion pipe 111.

[0036] As Figures 1 - 2 and Figure 9 shown, in this embodiment, specifically, the detection component 2 includes multiple groups of induction wires 21 and multiple groups of receiving blocks. The multiple groups of induction wires 21 are equidistantly installed inside the planting table 12. The multiple groups of receiving blocks are equidistantly installed on the induction wires 21. The induction wires 21 are connected to the controller 9, and the induction wires 21 cooperate with the spraying component 3;

[0037] When the detection component 2 of the device is in use, it can detect the current humidity of the planting table 12 so as to irrigate the planting table 12 according to the humidity, thereby supplementing the water of the planted plants. Specifically, when in use, the controller 9 can energize the induction wire 21 to control the induction wire 21 to emit current to the receiving block. Since the external humidity will affect the conductivity, when the humidity in the planting table 12 is in a normal state, the conductivity of the induction wire 21 will be between the normal thresholds. When the humidity of the planting table 12 is low, the conductivity of the induction wire 21 will exceed the threshold at this time. When the humidity of the planting table 12 is high, the conductivity of the induction wire 21 will be lower than the threshold. Furthermore, the controller 9 can spray the planting table 12 by itself according to the detection component 2.

[0038] As Figure 1 shown, in this embodiment, specifically, when the conductivity of the induction wire 21 drops to the threshold: the corresponding spray head 36 will stop replenishing water;

[0039] When the conductivity of the induction wire 21 is within the threshold: the corresponding spray head 36 will not stop replenishing water;

[0040] When the humidity in the planting table 12 is in a normal state, the conductivity of the induction wire 21 will be between the normal thresholds. When the humidity of the planting table 12 is low, the conductivity of the induction wire 21 will exceed the threshold at this time. When the humidity of the planting table 12 is high, the conductivity of the induction wire 21 will be lower than the threshold. Furthermore, the controller 9 can spray the planting table 12 by itself according to the detection component 2.

[0041] As Figures 1 - 2 and Figure 5 shown, in this embodiment, specifically, the spray component 3 includes two groups of water storage tanks 31. Above one group of water storage tanks 31, a fertilizer adding component 7 and a water pump 32 are installed. The output end of the water pump 32 is installed with a conduit 33. The conduit 33 is respectively matched with multiple groups of spray components 3. The spray component 3 further includes a spray plate 34. Inside the spray plate 34, multiple groups of spray pipes 35 are installed. At the bottom of the spray plate 34, multiple groups of spray heads 36 are installed. The spray heads 36 are connected to the spray pipes 35;

[0042] When the spray component 3 of the device is in use, it can irrigate and spray the planted plants on the planting table 12 by itself according to the results detected by the detection component 2. And when irrigating the planting table 12, the staff can also appropriately add fertilizers to the planted plants according to the current state of the planted plants, so as to accelerate the growth of the planted plants. Specifically, when in use, the water pump 32 can suck the liquid in the water storage tank 31 and supply it to the spray component 3 through the conduit 33. Since the conduit 33 is connected to the spray pipe 35, the liquid can be supplied to the spray head 36 through the spray pipe 35, thereby irrigating the plants on the planting table 12 through the spray head 36.

[0043] AsFigure 7 As shown in the figure, in this embodiment, specifically, the fertilizer adding component 7 includes a tank body 71. The tank body 71 is connected to the water storage tank 31. A valve is provided at the connection between the tank body 71 and the water storage tank 31. Water-soluble fertilizer is provided inside the tank body 71. A storage amount monitoring component 8 is installed inside the tank body 71. The storage amount monitoring component 8 can detect the total amount of water-soluble fertilizer in the current tank body 71.

[0044] When the fertilizer adding component 7 of the device is in use, it can quantitatively add water-soluble fertilizer according to the total amount of liquid in the water storage tank 31, so that the liquid in the water storage tank 31 can be matched with an appropriate amount of water-soluble fertilizer, so that when watering the planted plants, the water-soluble fertilizer can be irrigated onto the planted plants together. And mainly through the storage amount monitoring component 8, the storage amount of water-soluble fertilizer can be monitored all the time, so that the amount of water-soluble fertilizer input each time can be known.

[0045] As Figure 8 shown in the figure, in this embodiment, specifically, the storage amount monitoring component 8 includes a detection tube 81. A detection spring 82 and a detection plate 83 are provided inside the detection tube 81. A plurality of groups of limit grooves 811 are provided at the bottom of the detection tube 81. The detection spring 82 can contract after being electrified. One end of the detection spring 82 is connected to the detection tube 81, and the other end of the detection spring 82 is connected to the detection plate 83. The detection plate 83 cooperates with the limit grooves 811. A plurality of groups of conductive points 831 are provided on the detection plate 83. A plurality of groups of conductive sheets 821 are installed on the inner wall of the detection tube 81. The plurality of groups of conductive sheets 821 are equidistantly installed on the inner wall of the detection tube 81. The conductive points 831 cooperate with the conductive sheets 821.

[0046] When the storage amount monitoring component 8 is in use, it can monitor the content of the added water-soluble fertilizer each time when adding water-soluble fertilizer, and ensure the amount of water-soluble fertilizer added each time. Specifically, when in use, first, the detection spring 82 needs to be electrified so that the detection spring 82 can contract. Then, water-soluble fertilizer needs to be added into the tank body 71. After adding the water-soluble fertilizer, the electrical connection of the detection spring 82 can be disconnected, so that the detection plate 83 can support on the water-soluble fertilizer. At this time, the conductive points 831 on the detection plate 83 will contact the conductive sheets 821 on the inner wall of the detection tube 81. Furthermore, at this time, through the cooperation between the conductive points 831 and the conductive sheets 821, the controller 9 can know the current position of the detection plate 83, and combined with the descending amplitude of the detection plate 83, the total amount of added water-soluble fertilizer can be known.

[0047] As Figure 6 shown in the figure, in this embodiment, specifically, the separation component 6 includes a separation motor 61 and a separation tube 62. The diversion tube 111 is connected to the feed inlet of the separation tube 62. A separation screw 63 is installed inside the separation tube 62. The output end of the separation motor 61 is connected to the separation screw 63.

[0048] When in use, the separation component 6 of the device can separate the liquid discharged from the diversion pipe 111. Since the liquid collected by the diversion pipe 111 will carry a small amount of cultivation soil, the liquid and solid therein are separated, and the separated liquid will be discharged into another water storage tank 31, facilitating the utilization of the recycled liquid.

[0049] As Figure 1 shown, in this embodiment, specifically, a controller 9 is installed on the side of the support frame 11. The controller 9 is connected to the main body 1 of the planting device, and a control panel 91 is arranged on the controller 9.

[0050] When in use, the entire main body 1 of the planting device can be controlled through the controller 9. Since the control panel 91 is arranged on the controller 9, the staff can indirectly control the entire main body 1 of the planting device through the control panel 91.

[0051] Working principle: When in use, seeds or seedlings need to be planted in the planting table 12 first, and according to the specifications of the planting table 12, the seeds or seedlings should be evenly planted in the planting table 12. Then the device can cultivate the seeds or seedlings. Specifically, when in use, the detection component 2 can continuously detect the dryness and humidity of the entire planting table 12. When the detection component 2 detects that the planting table 12 is relatively dry, the controller 9 will control the spraying component 3 to irrigate the plants in the planting table 12 through the spraying component 3. When the humidity in the planting table 12 is reduced to a specific threshold by the spraying component 3, the controller 9 will control the irrigation component to stop working. While the spraying component 3 is working, the staff can add water-soluble fertilizers according to the current condition of the plants, so that the water-soluble fertilizers can be irrigated onto the plants together while the spraying component 3 is working, thereby promoting the growth of the plants. After that, to ensure that the plants on the device can maintain a ventilated and breathable position, the device can separate each group of planting tables 12 after spraying, increasing the distance between two adjacent planting tables 12, so that air can flow more smoothly between the devices. At the same time, when the device needs sunlight, it can also adjust the position of the planting table 12 according to the current situation, so that the plants on the planting table 12 can absorb sunlight more comprehensively. Therefore, when in use, the device can cultivate plants more fully.

[0052] For those skilled in the art, it is obvious that the present invention is not limited to the details of the above-described exemplary embodiments, and the present invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the present invention. Therefore, from any point of view, the embodiments should be regarded as exemplary and non-limiting. The scope of the present invention is defined by the appended claims rather than the above description. Therefore, all changes falling within the meaning and scope of the equivalent elements of the claims are intended to be embraced within the present invention. Any reference signs in the claims should not be construed as limiting the claims involved.
