Detailed Description of the Invention

[0039] The following further elaborates on this application with reference to the accompanying drawings. Figure 1-8 A further detailed description of this application will be given below.

[0040] An embodiment of this application discloses a three-dimensional planting device. Refer to Figure 1 and Figure 2 . The three-dimensional planting device includes a hydroponic component 1 for planting hydroponic vegetables; a light-shielding cultivation component 2 disposed below the hydroponic component 1. The side wall of the light-shielding cultivation component 2 is a light-shielding mechanism 22, and an accommodation cavity for planting edible fungi is formed inside the light-shielding cultivation component 2.

[0041] Specifically, the hydroponic component 1 includes a hydroponic tank 11, and hydroponic vegetables can be planted by filling the hydroponic tank 11 with a culture solution. The hydroponic tank 11 includes a bottom plate and side walls. In order to facilitate the fixation of hydroponic vegetables in the hydroponic tank 11, a net-shaped support frame (not shown in the figure) can also be provided in the hydroponic tank. The support frame is provided with a number of through holes, and the hydroponic vegetables can be fixed in the through holes.

[0042] Refer to Figure 2 . Since the culture solution will naturally volatilize in the hydroponic tank 11 and the nutrient content of the culture solution will gradually decrease as the hydroponic vegetables grow, preferably, the hydroponic component 1 further includes a liquid inlet 12 and a liquid outlet 13 provided at both ends of the hydroponic tank 11. Connecting the liquid inlet 12 and the liquid outlet 13 to a container containing the culture solution by a pump body can realize the circulating flow of the culture solution in the hydroponic tank and ensure sufficient nutrient supply for the hydroponic vegetables.

[0043] Preferably, in order to enable the culture solution to reach the roots of each hydroponic vegetable evenly, a diversion channel 14 is further provided at the bottom of the hydroponic tank 11. The diversion channel 14 is used to guide the flow direction of the culture solution. The diversion channel 14 can be made in the hydroponic tank 11 by using a partition 15. The partition 15 can be made of metal or non-metal materials, preferably an organic polymer material with strong corrosion resistance. The diversion channel 14 can be a swirling structure. After the culture solution flows in from the liquid inlet 12, it swirls along the diversion channel 14, so that the hydroponic vegetables arranged along the diversion channel 14 can all come into full contact with the culture solution. Optionally, the diversion channel 14 can also be an interconnected grid-like structure, which can be selected by those skilled in the art according to needs and will not be specifically limited here.

[0044] Refer to Figure 1 and Figure 3, The light-shielding cultivation component 2 is arranged below the hydroponic component 1. The light-shielding cultivation component 2 includes a top plate 21 and columns (not shown in the figure) fixedly connected to the four corners of the top plate 21. On both sides below the top plate 21, light-shielding mechanisms 22 perpendicular to the top plate are respectively arranged. Both ends of the light-shielding mechanism 22 are fixedly connected to the columns. The light-shielding mechanisms 22 on both sides are parallel to each other. A receiving cavity is formed between the light-shielding mechanism 22, the top plate 21 and the ground. The top plate 21 is detachably connected or fixedly connected to the bottom plate of the hydroponic tank 1. Optionally, the top plate 21 can also be integrally formed with the bottom plate of the hydroponic tank 1.

[0045] The light-shielding mechanism 22 includes at least two layers of parallel light-transmitting plates 221. Light-transmitting through-holes 222 are evenly arranged on each layer of light-transmitting plate 221. The central axes of the light-transmitting through-holes 222 on adjacent light-transmitting plates 221 do not coincide. The diameters of the light-transmitting through-holes 222 on adjacent light-transmitting plates 221 can be the same or different. The diameter of the light-transmitting through-hole is 0.3 - 2 cm. The center distance of the light-transmitting through-holes 222 on the same light-transmitting plate 221 is 1 - 9 times the diameter of the light-transmitting through-hole 222. When the diameters of the light-transmitting through-holes 222 on adjacent light-transmitting plates 221 are the same, the distance between adjacent light-transmitting plates 221 is 0.1 - 1 times the diameter of the light-transmitting through-hole 222. When the diameters of the light-transmitting through-holes 222 on adjacent light-transmitting plates 21 are different, the distance between adjacent light-transmitting plates 221 can be either 0.1 - 1 times the diameter of the larger-diameter light-transmitting through-hole 222 or 0.1 - 1 times the diameter of the smaller-diameter light-transmitting through-hole 222, which can be selected by those skilled in the art according to needs. By arranging the light-transmitting through-holes 222 on the light-transmitting plate 221 and making the central axes of the light-transmitting through-holes 222 on adjacent light-transmitting plates 221 not coincide, the edible fungi in the light-shielding cultivation component 2 can not only obtain the necessary light for growth but also avoid the influence of strong light on the growth of edible fungi. At the same time, it can also carry out gas and moisture exchange with the external environment.

[0046] Furthermore, since the light intensity changes with seasons and weather, in order to enable the edible fungi in the light-shielding cultivation component 2 to adapt to different seasons and weather, the light-shielding cultivation component 2 further includes an adjustment mechanism 23 for adjusting the position of the light-transmitting plate in three spatial directions.

[0047] Refer to Figure 4 and Figure 5 , The adjustment mechanism 23 includes a support plate 231 arranged at the upper end of the light-transmitting plate 221 close to the receiving cavity side, a first rack 232 arranged on the upper surface of the support plate 231, a first gear 233 engaged with the first rack 232, second racks 235 arranged on both end faces of the light-transmitting plate 221, second gears 236 engaged with the second racks 235, a third rack 237 arranged at the bottom end of the light-transmitting plate 221, and a third gear 238 engaged with the third rack 237.

[0048] The support plate 231 is parallel to the hydroponic tank 1 and perpendicular to the light-transmitting plate 221. The support plate 231 is fixedly connected to the light-transmitting plate 221. The first rack 232 is perpendicular to the plane where the light-transmitting plate 221 is located, and the first gear 233 meshes with the first rack 232. When the first gear 233 rotates driven by the motor, the light-transmitting plate 221 can be driven by the first rack 232 to move in a direction perpendicular to the light-transmitting plate 221, thereby adjusting the vertical distance between adjacent light-transmitting plates 21.

[0049] The second rack 235 is vertically arranged on both end faces of the light-transmitting plate 221 and fixedly connected to the light-transmitting plate 221. The second gear 236 meshes with the second rack 235. When the second gear 236 rotates driven by the motor, the light-transmitting plate 221 can be driven by the second rack 235 to move in the vertical direction.

[0050] The third rack 237 is horizontally arranged at the bottom end of the light-transmitting plate 221. The third rack 237 is fixedly connected to the light-transmitting plate 221. The third gear 238 is arranged below the third rack 237 and meshes with the third rack 237. When the third gear 238 rotates driven by the motor, the light-transmitting plate 221 can be driven by the third rack 237 to move along the length direction.

[0051] In order to ensure that when the light-transmitting plate 221 moves in any direction, the gears and racks in the other two directions always remain in the meshing state, the adjustment mechanism further includes a first frame, a second frame and a third frame. The three frames are nested with each other and the planes where they are located are perpendicular to each other. The first gear 233 is fixedly connected to the first frame. The first frame can move relative to the second frame and the third frame to ensure that when the light-transmitting plate 221 moves driven by the first gear 233, the second gear 235 and the second rack 236 always remain meshed, and the third gear 238 and the third rack 237 always remain meshed; the second gear 236 is fixedly connected to the second frame. The second frame can move relative to the first frame and the third frame to ensure that when the light-transmitting plate 221 moves driven by the second gear 236, the first gear 233 and the second rack 232 always remain meshed, and the third gear 238 and the third rack 237 always remain meshed; the third gear 238 is fixedly connected to the third frame. The third frame can move relative to the first frame and the second frame to ensure that when the light-transmitting plate 221 moves driven by the third gear 238, the first gear 233 and the second rack 232 always remain meshed, and the second gear 235 and the second rack 236 always remain meshed.

[0052] By providing an adjustment mechanism 23 on each light-transmitting plate 221, the position of the light-transmitting plate 221 in three spatial directions can be adjusted, thereby regulating the positional relationship of the light-transmitting through-holes 222 on the multiple layers of light-transmitting plates 221. For example, when the light intensity is strong in summer, the position of the multiple layers of light-transmitting plates 221 can be adjusted to increase the spacing between the axes of the light-transmitting through-holes 222 on adjacent light-transmitting plates 221, and the light is blocked through the dislocation relationship of the multiple layers of light-transmitting plates 221 to reduce the light intensity inside the light-shielding cultivation assembly 2; when the light intensity is weak in winter, the position of the multiple layers of light-transmitting plates 221 can be adjusted to reduce the spacing between the axes of the light-transmitting through-holes 222 on adjacent light-transmitting plates 221, reducing the light-blocking effect, so that more light can enter the inside of the light-shielding cultivation assembly 2 to increase the temperature.

[0053] Referring to Figure 6 and Figure 7 , to facilitate arranging the fungus sticks inside the light-shielding cultivation assembly 2, the three-dimensional planting device further includes a conveying assembly 3. The conveying assembly 3 includes a track 31, a trailer 32, and a traction mechanism 33. Among them, the track 31 is arranged on the ground inside the light-shielding cultivation assembly 2 and is parallel to the side wall of the cavity; the trailer 32 can reciprocate along the track 31, and connecting components 321 for connecting with adjacent trailers 32 are provided at both ends of the trailer 32, and the connecting components 321 can be hooks; the traction mechanism 33 includes a first roller 331 and a second roller 332 arranged at both ends outside the light-shielding cultivation assembly 2, the first roller 331 and the second roller 332 are driven to rotate by a motor, a rope 333 is arranged between the first roller 331 and the second roller 332, both ends of the rope 333 are wound around the first roller 331 and the second roller 332, and the rope 333 is fixedly connected to the trailer 32.

[0054] During operation, multiple trailers 32 can be connected end to end through the connecting components 321, and the rope 333 is fixedly connected to one of the trailers 32. When the first roller 331 rotates actively driven by the motor, the rope 333 drags the multiple trailers 32 connected together to move along the track 31 towards the side of the first roller 331, and the second roller 332 releases the rope passively; when the second roller 332 rotates actively driven by the motor, the rope 333 drags the multiple trailers 32 connected together to move along the track 31 towards the side of the second roller 331, and the first roller 331 releases the rope passively. After the fungus sticks are placed on the trailer 32, under the dragging of the first roller 331 and the second roller 332, the trailer 32 is dragged into the inside of the light-shielding cultivation assembly 2, improving the arrangement efficiency of the fungus sticks.

[0055] Optionally, referring to Figure 8, To improve the application efficiency of the conveying component 3 and the arrangement efficiency of the mushroom sticks, two three-dimensional planting devices can be arranged in parallel. One of them includes a track 31, a trailer 32, and a traction mechanism 33, and the other one has a track 31 and a trailer 32 arranged in the light-shielding cultivation component, without including the traction mechanism 33. The two ends of the tracks arranged in the two three-dimensional planting devices are connected into a closed-loop shape through arc-shaped tracks, and the trailers arranged in the two three-dimensional planting devices are connected end to end. One of the trailers in the three-dimensional planting device provided with the traction mechanism 33 is fixedly connected to the rope 333 included in the traction mechanism 33. When dragging the trailer 32 through the first roller 331 and the second roller 332, all the trailers 32 on the track 31 of the two three-dimensional planting devices can be driven to move synchronously. The staff only needs to complete the arrangement of the mushroom sticks on all the trailers 32 at the arc-shaped tracks at both ends. After the mushroom sticks are arranged in the light-shielding cultivation component 2, the two ends of the three-dimensional planting device can be covered with light-shielding cloth.

[0056] In the embodiment of the present application, the height of the hydroponic tank of the three-dimensional planting device can be 0.8 - 1.5 m, the width can be 1.2 - 2 m, and the length can be 5 - 200 m; correspondingly, the length and width of the light-shielding cultivation component 2 are the same as those of the hydroponic tank 11, and the height of its accommodating cavity can be set according to the thickness of the arrangement of the edible mushroom sticks. The length of the trailer 32 can be 1 - 3 m, and the width can be 0.8 - 1.8 m. Those skilled in the art can also set the dimensions of each component of the three-dimensional planting device according to needs, and no specific limitation is made here.

[0057] The embodiment of the present application also discloses a three-dimensional planting system, including the aforementioned three-dimensional planting device, a greenhouse, and a temperature and humidity control device.

[0058] The greenhouse is arranged outside the three-dimensional planting device and completely covers the three-dimensional planting device. The greenhouse can be made of light-transmitting plastics, glass and other materials to ensure sufficient light in the greenhouse. The greenhouse can be provided with windows that can be opened and closed for air circulation in necessary situations.

[0059] The temperature and humidity control device is used to control the temperature and humidity in the greenhouse to ensure that the crops planted in the greenhouse can grow under suitable temperature and humidity conditions. Among them, the temperature and humidity control device can include an air conditioner and / or a gas heating device for controlling temperature, and a humidifier and / or a ventilation device for controlling humidity. Those skilled in the art can determine the composition of the temperature and humidity control device according to needs, and no specific limitation is made here.

[0060] The three-dimensional planting device and system provided by the present application can simultaneously plant edible fungi and hydroponic vegetables in the vertical direction, with high space utilization rate. The light-shielding mechanism 22 can adjust the light intensity in the light-shielding cultivation component 2, which not only reduces the impact of strong light on the growth of edible fungi but also ensures the circulation of air and moisture. During the day, the hydroponic vegetables not only release oxygen through photosynthesis to create conditions for the respiration of edible fungi but also increase the air humidity through transpiration. The carbon dioxide released during the respiration of edible fungi is beneficial to the photosynthesis of hydroponic vegetables, and the two benefit from each other. The setting of the conveying component 3 improves the arrangement efficiency of the fungus sticks in the light-shielding cultivation component 2.

[0061] The three-dimensional planting device and system provided by the present application are not limited to planting hydroponic vegetables in the upper layer and edible fungi in the lower layer. Other light-loving crops can also be planted by filling the hydroponic component 1 with soil, and other crops with lower light requirements can also be planted in the light-shielding cultivation component 2.

[0062] The above are all the preferred embodiments of the present application. The protection scope of the present application is not limited by this. Therefore, all equivalent changes made according to the structure, shape, and principle of the present application should be covered within the protection scope of the present application.
