[0027] The following will clearly and completely describe the technical solutions of the present invention in conjunction with the embodiments. Obviously, the embodiments described are only a part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0028] like Figures 1-6 As shown, one embodiment of the present invention provides a potato planting device, comprising a planting barrel 1, a plurality of planting barrels and a nutrient solution supply mechanism 7; the planting barrel 1 has an open top, and its top opening is covered with a barrel cover 2; the plurality of planting barrels are vertically arranged inside the planting barrel 1, and a grid plate 5 is installed inside each planting barrel. The grid plate 5 divides the internal space of the planting barrel into a top space and a bottom space, the bottom space is used to accommodate nutrient solution, and the top space is used to plant potatoes, and a liquid inlet is provided on the inner bottom wall of the planting barrel;

[0029] The nutrient solution supply mechanism 7 is connected to the liquid inlets of the plurality of planting tubes and is used to inject the nutrient solution into the bottom space of the plurality of planting tubes.

[0030] The potato planting device in this embodiment can be used to plant both young potato seedlings and tubers. When planting seedlings, the lid 2 of the planting barrel 1 is not required, ensuring that the seedlings can photosynthesize normally. During planting, the potato seedlings are placed on the grid plate 5 within the planting barrel. A nutrient solution supply mechanism 7 then injects nutrient solution into the bottom chamber of the planting barrel. The roots of the potato seedlings penetrate the grid plate 5 and penetrate into the nutrient solution, absorbing nutrients and water. Cultivated by the nutrient solution, the potato seedlings can maintain their growth.

[0031] When planting germinated potato tubers in this device, the germinated tubers are first placed on the mesh plate 5 inside the planting barrel. The barrel cover 2 is then placed on the planting barrel 1. Nutrient solution is then injected into the bottom chamber of the planting barrel using the nutrient solution supply mechanism 7. The nutrient solution covers the bottom of the tubers, and the roots of the germinated tubers pass through the mesh plate 5, absorbing nutrients and water from the nutrient solution, and grow tubers in the top chamber. Because the planting barrel 1 is relatively sealed, it provides a heat-insulating, moisture-retaining, and dark environment, which is conducive to the development and growth of rhizomes.

[0032] It can be seen that both potato test tube seedlings and potato blocks can be planted soillessly through the potato planting device, without the need to be planted in the field. Instead, they can be planted in the potato planting device, where the environment is easy to control and the yield can be increased.

[0033] As a preferred embodiment, Figure 4 As shown, the planting barrel includes a plurality of first planting barrels 3 and a plurality of second planting barrels 4 and a fixing assembly. The plurality of first planting barrels 3 are evenly arranged around the axis of the planting barrel 1, and the plurality of second planting barrels 4 are evenly arranged around the axis of the planting barrel 1. The plurality of first planting barrels 3 enclose a cylindrical space, and the second planting barrels 4 are located within the cylindrical space. That is, the distance between the second planting barrels 4 and the axis of the planting barrel 1 is less than the distance between the first planting barrels 3 and the axis of the planting barrel 1. The first planting barrels 3 and the second planting barrels 4 are suspended inside the planting barrel 1 by the fixing assembly.

[0034] Furthermore, the fixing assembly includes a plurality of first connecting rods 8, a plurality of fixing rods 9, a plurality of rod bodies 10 and a plurality of second connecting rods 11. Two adjacent first planting barrels 3 are connected by the first connecting rods 8. The fixing rods 9 correspond to the first connecting rods 8 one by one. One end of the fixing rod 9 is connected to the corresponding first connecting rod 8, and the other end is connected to the inner wall of the planting barrel 1. Two adjacent second planting barrels 4 are connected by the second connecting rod 11. The rod body 10 is provided between the first planting barrel 3 and the second planting barrel 4 to connect the first planting barrel 3 and the second planting barrel 4.

[0035] This arrangement allows more planting tubes to be arranged within a limited space so as to plant more potatoes and make rational use of the space.

[0036] It should be noted that in the above embodiment, the planting tube is divided into two circles, inner and outer. In some feasible embodiments, the planting tube can be arranged in three or four circles. That is, the specific number of circles of the planting tube is not specifically limited and is determined by the size of the space in the planting barrel 1.

[0037] In addition, if Figure 3 As shown, a grid plate 5 is horizontally installed inside each planting tube, and a liquid inlet is opened on the inner bottom wall of each planting tube.

[0038] As a preferred embodiment, Figure 3 and Figure 5 As shown, the nutrient solution supply mechanism 7 includes a water pump, an outer circular tube 702, an inner circular tube 703, a water supply pipe 701 and a plurality of connecting tubes 704. Among them, the diameter of the outer circular tube 702 is larger than that of the inner circular tube 703. The outer circular tube 702 and the inner circular tube 703 are both arranged inside the planting barrel 1 and lower than the first planting barrel 3. The outer circular tube 702, the inner circular tube 703 and the planting barrel 1 are coaxially arranged. The outer circular tube 702 is located directly below the plurality of first planting barrels 3, and the inner circular tube 703 is located directly below the plurality of second planting barrels 4. The outer circular tube 702 is provided with a plurality of first liquid outlet pipes 705 corresponding one-to-one to the first planting barrels 3, and the top end of the first liquid outlet pipe 705 is connected to the liquid inlet of the corresponding first planting barrel 3; the inner circular tube 703 is provided with a plurality of second liquid outlet pipes 706 corresponding one-to-one to the second planting barrel 4, and the top end of the second liquid outlet pipe 706 is connected to the liquid inlet of the corresponding second planting barrel 4. As shown Figure 5 Multiple connecting pipes 704 are evenly spaced around the axis of inner tube 703, with one end of each connecting pipe 704 connected to outer tube 702 and the other end connected to inner tube 703. One end of water supply pipe 701 is connected to outer tube 702, while the other end extends from planter barrel 1 and connects to the water pump outlet. Multiple support rods 707 are evenly fixedly connected to outer tube 702 around its axis, with the ends of support rods 707 away from outer tube 702 fixed to the inner wall of planter barrel 1.

[0039] In this way, the nutrient solution is pumped into the water supply pipe 701 through the water pump, and the nutrient solution further flows into the outer circular tube 702, and then flows into the inner circular tube 703 through multiple connecting tubes 704. Part of the nutrient solution in the outer circular tube 702 flows into the first planting tube 3 from the first liquid outlet pipe 705 on the outer circular tube 702, and the nutrient solution in the inner circular tube 703 flows into the second planting tube 4 from the second liquid outlet pipe 706 on the inner circular tube 703.

[0040] As a preferred embodiment, solenoid valves are installed on both the first and second liquid outlet pipes 705, 706 to control their on / off function. To facilitate control of the nutrient solution level in the bottom chamber of each planting tube, a liquid level gauge is installed in the bottom chamber of each planting tube. The level gauge and solenoid valve are each connected to a controller mounted on the outer wall of the planting tube 1.

[0041] In this way, when injecting nutrient solution into the planting tube, the controller controls all the solenoid valves to open, and the nutrient solution in the bottom space of the planting tube becomes more and more, and its water level gradually rises. The hydraulic gauge sends the liquid level signal to the controller. When the set water level is reached, the controller controls the corresponding solenoid valve to close, and the nutrient solution can no longer be injected into the planting tube.

[0042] like Figure 2 and Figure 3 As shown, a lid 2 is placed on the top opening of the planting barrel 1, and air holes are provided on the lid 2. It should be noted that the formation and growth of potato seed pieces require a breathable, cool and moist soil environment. The suitable temperature range for tuber growth is significantly smaller than that for stem and leaf growth, and a relatively dark environment is required. Therefore, after the potato seed pieces are placed in the planting barrel, the lid 2 needs to be closed to ensure that the interior of the planting barrel 1 is in a relatively dark environment. The air holes on the lid 2 are used to allow outside air to enter, ensuring that the planting barrel 1 is in a breathable state. When planting potato seedlings, the lid 2 can be removed.

[0043] As a preference, in order to save space to the greatest extent possible, reduce the floor area. Figure 1 and Figure 3 As shown, a plurality of upper legs 102 and lower legs 101 corresponding to each other are mounted on the outer wall of the planting barrel 1, and both the upper legs 102 and the lower legs 101 are L-shaped. The plurality of upper legs 102 are evenly arranged around the axis of the planting barrel 1, with one end of the upper leg 102 fixed to the side of the planting barrel 1 near its top, and the other end pointing upwards. A slot for inserting the lower leg 101 is provided at the top of the upper leg 102, and the plurality of lower legs 101 are evenly arranged around the axis of the planting barrel 1, with one end of the lower leg 101 fixed to the side of the planting barrel 1 near its bottom, and the other end pointing downwards.

[0044] Therefore, one planting barrel 1 can be placed on top of another planting barrel 1, so that the lower legs 101 of the upper planting barrel 1 are inserted into the slots of the upper legs 102 of the lower planting barrel 1. In this way, multiple planting barrels 1 can be stacked together, saving space and reducing floor space.

[0045] As an optional embodiment, Figure 3 As shown, when planting potato seedlings, a horizontally positioned straightening member 6 can be installed inside the planting tube. The straightening member 6 comprises a circular ring and a crossbar. One end of the crossbar is fixedly connected to the side of the circular ring, and the other end of the crossbar is screwed to the inner wall of the planting tube. The circular ring and the planting tube are arranged coaxially. Thus, when planting potato seedlings, the seedlings are placed in the circular ring of the straightening member 6 to maintain an upright position, effectively preventing the potato seedlings from falling inside the planting tube.

[0046] As an optional embodiment, Figure 6As shown, a planting bed 12 is placed on the mesh panel 5 of each planting barrel. Connected to the bottom of the planting bed 12 is an absorbent wick 13, which extends through the mesh panel 5 into the underlying space. Specifically, the planting bed 12 must be absorbent, such as made of a material like sponge or paper, and also have a certain water-retention capacity to provide sufficient moisture and a suitable temperature for the seed pieces. Potato pieces can then be placed on the planting bed 12 and the barrel lid 2 closed. The roots growing from the seed pieces will then pass through the mesh panel 5, absorbing nutrients and moisture from the nutrient solution.
