DETAILED DESCRIPTION

[0039] In order to make the technical means, creative features, purposes and effects realized by the application easy to understand, the application is further described below in combination with specific embodiments.

[0040] As Figures 1 to 7 shown, the cultivation device for garden landscape plants provided by the application comprises a cultivation box 1 and a transparent cover 2; the transparent cover 2 is fixedly connected to the top of the cultivation box 1; a water storage tank 3 is formed at the upper edge of the cultivation box 1;

[0041] A net-shaped isolation plate 4 is fixedly connected inside the cultivation box 1; a planting cavity 5 is formed above the isolation plate 4, and a water storage cavity 6 is formed below the isolation plate 4; filter cotton 7 is arranged on the upper side of the isolation plate 4; the surface of the filter cotton 7 is used for laying soil;

[0042] An irrigation assembly is arranged inside the planting cavity 5; the irrigation assembly is used for uniformly discharging water entering from the water storage tank 3 into the soil; the irrigation assembly comprises a connecting groove 8 formed in the side wall of the planting cavity 5, and the connecting groove 8 and the water storage tank 3 are communicated through a guide groove 9; a mounting plate 10 is fixedly connected inside the connecting groove 8; a plurality of irrigation pipes 11 are uniformly distributed on the surface of the mounting plate 10, and the irrigation pipes 11 are embedded in the soil; a plurality of water distribution eyes 12 are uniformly distributed on the surface of the irrigation pipes 11;

[0043] The water storage cavity 6 is internally provided with a water guide assembly; the water guide assembly is used for transmitting water inside the water storage cavity 6 upwards to the inside of the soil.

[0044] The prior art garden landscape plant cultivation device protects the plants by arranging a glass plate on the upper side of the device to prevent the plants from being damaged, and tourists can observe the plants in the device through the glass plate. However, since the plants and the soil are both blocked by the glass plate, rainwater cannot enter the soil inside the device when it rains, and the plants cannot be watered by natural irrigation. Therefore, the plants always need to be watered by artificial irrigation or external pipelines, which is complicated and consumes a large amount of water resources.

[0045] The transparent cover 2 is also used to block and protect the plants inside the device from external objects such as tourists, birds, natural disasters, etc., to ensure the normal growth conditions of the plants. When it rains, the rainwater flows into the connecting groove 8 through the water storage groove 3 and the guide groove 9, and then enters the irrigation pipes 11. The rainwater uniformly flows into the soil inside the planting cavity 5 through the water distribution eyes 12 on the surface of the irrigation pipes 11, thereby watering the plants. The rainwater improves the uniformity of the distribution of water in the soil. After the rainwater soaks and evenly waters the soil, the excess rainwater can seep downward and enter the water storage cavity 6 through the filter cotton 7 and the isolation plate 4, thereby collecting and storing the rainwater. After the rain stops, the water in the soil gradually dries, and the water in the water storage cavity 6 is retransmitted to the soil inside by the water guide assembly, so that the soil maintains a certain humidity for a long time, thereby providing sufficient water demand for the plants and prolonging the maintenance time of rainwater irrigation.

[0046] The filter cotton 7 can effectively store water and filter the soil in the rainwater, thereby reducing the problem that the soil is continuously brought into the water storage cavity 6 when the rainwater seeps from the soil to the water storage cavity 6.

[0047] The device uses natural irrigation to water the plants in the device during the period of abundant rainfall, without the need for excessive human intervention, thereby fully utilizing the rainwater and saving water resources. In addition, in order to meet the growth conditions of the plants as much as possible, a water pipe can be connected to the connecting groove 8, or water can be manually added to the water storage groove 3, thereby providing basic irrigation measures for the plants during the period of low rainfall and ensuring that the soil inside has sufficient water.

[0048] The cultivation box 1 is uniformly provided with a group of air vents 13 and overflow holes 14 on the side surface; the air vents 13 are in communication with the planting cavity 5; and the overflow holes 14 are in communication with the top of the water storage cavity 6. The air vents 13 are used for the respiration of the plants, and the overflow holes 14 are used for drainage. When the water storage cavity 6 collects sufficient water, the excess water is discharged outward through the overflow holes 14, thereby preventing too much water from flowing upward into the soil and causing the roots of the plants to rot.

[0049] The installation frame 15 and the filter screen 16 are arranged, so that the sundries from the outside can be blocked during the collection of rainwater, and the structures such as the water storage tank 3, the guide groove 9 and the connecting groove 8 are prevented from being blocked.

[0050] As a preferred embodiment of the present application, the inductive groove 17 is arranged at the side wall of the water storage cavity 6 and is located below the water storage tank 3; the float 18 is slidably connected in the inductive groove 17; the movable pad 19 is arranged in the water storage tank 3; the connecting rod 20 is fixedly connected between the movable pad 19 and the float 18 and penetrates through the side wall of the cultivation box 1 and is slidably connected therewith. The float 18 in the inductive groove 17 can float up and down with the change of the water level in the water storage cavity 6. When the water storage capacity in the water storage cavity 6 gradually increases, the water surface reaches the vicinity of the overflow hole 14, at this time, it is not necessary to continue to store water, the float 18 moves to the top of the inductive groove 17 with the water surface, and drives the movable pad 19 upwardly to be attached to the installation frame 15 through the connecting rod 20, so that the movable pad 19 blocks the top of the water storage tank 3, so that the subsequent rainwater is difficult to enter the inside of the water storage tank 3, and the rainwater is prevented from continuously entering the water storage cavity 6 through the soil and being discharged from the overflow hole 14, so that the soil and the nutrients in the soil are prevented from being washed away by the flowing water, and the soil and nutrient loss problem is further avoided.

[0051] As a preferred embodiment of the present application, the water guide assembly includes a group of water guide strips 21 penetrating through the isolation plate 4 and the filter cotton 7; the water storage cavity 6 is fixedly connected with a group of water guide columns 22; the water guide columns 22 and the water guide strips 21 are made of water-absorbing materials and correspond to each other, and the materials can be sponge, foam, cotton cloth and the like;

[0053] After the water storage work is finished, the water guide strip 21 and the water guide column 22 are normally kept in a separated state, the moisture content in the soil is detected in real time through the humidity sensor 23, when the moisture content is lower than a certain degree, the controller controls the electromagnet 26 to be powered on and repels the magnetic block 25, the lifting plate 24 drives the plurality of water guide columns 22 to deform upward synchronously, so that the water guide column 22 can be in contact with the water guide strip 21, and then the water in the water storage cavity 6 is transmitted upward to the soil inside through the water guide column 22 and the water guide strip 21, to provide water for plants, when the humidity sensor 23 detects that the moisture content in the soil is higher than a certain degree, the controller controls the electromagnet 26 to be powered off, the water guide column 22 automatically retracts downward and separates from the water guide strip 21, to cut off the path of water transmission upward, at this time the moisture in the water storage cavity 6 cannot be transmitted upward to the soil inside, by setting the water guide assembly, water is introduced into the soil only when the moisture content in the soil is low, on the one hand, it can further prevent the problem of high soil moisture content causing plant root suffocation and dilution of nutrients, on the other hand, it can maximize the use of water in the water storage cavity 6, reduce the speed of water loss and consumption, and prolong the time of water supply.

[0054] As a preferred embodiment of the present application, a group of wave-shaped deformation strips 27 are arranged between the irrigation pipe 11 and the cultivation box 1, and between adjacent irrigation pipes 11; the deformation strips 27 are made of water-swelling materials, such as expanded rubber, polymer hydrogel and the like, which can gradually shrink and recover after swelling and absorbing water, so as to realize repeated use. By arranging a plurality of deformation strips 27, the deformation strips 27 can absorb water from the soil and swell and deform when the moisture content of the soil increases each time, and then the deformation strips 27 press the soil around them, which can promote soil peristalsis and fluff, improve the hardening of the soil, improve the uniformity of water distribution in different positions of the soil, and be beneficial to the full respiration of plant roots and the absorption of water and nutrients in the soil. When the moisture content of the soil decreases, the deformation strips 27 gradually dry and shrink and recover.

Under normal circumstances, the guide channel 29 is in a blocked state under the blocking action of the roller 32, the controller controls the motor 31 to start periodically, drives the rotating shaft 30 and the roller 32 to rotate in the guide channel 29, and then the fertilizer at the bottom of the storage box 28 is continuously rolled into the spiral groove 33 and the gap between the roller 32 and the guide channel 29 under the action of the roller 32, and the fertilizer is gradually transported into the water storage cavity 6 by the rotating action of the spiral groove 33, so that the fertilizer is dissolved in water, and the soil is supplemented with nitrogen, phosphorus, potassium and other nutrients required by plants. In this process, the roller 32 can crush the fertilizer to reduce the size of the fertilizer particles, and the rotating shaft 30 can drive the water stirring blades 34 to rotate together, so as to stir the water in the water storage cavity 6, and further improve the dissolution efficiency of the fertilizer in water.
