Description

Technical Field

[0001] The utility model relates to the technical field of hydroponics, in particular to a water culture tray capable of increasing oxygen. Background Art

[0002] Hydroponic vegetables refer to vegetables whose roots mostly grow in nutrient solution, which is only provided with water, nutrients and oxygen by the nutrient solution. They are different from vegetables cultivated in traditional soil cultivation. Hydroponic vegetables are widely welcomed because of their short growth cycle and rich content of various vitamins and minerals necessary for the human body.

[0003] In the prior art, traditional vegetable hydroponics generally uses a pool or a trough as a container for nutrient solution. A floating board with planting holes is placed in the container as a carrier of the vegetables. The floating board can be raised and lowered as the liquid level of the nutrient solution changes. This can keep the roots of the vegetables in contact with the nutrient solution at all times, thereby reducing the frequency of adding nutrient solution to the container. However, the nutrient solution in the traditional pool or trough used for vegetable hydroponics has poor fluidity. In order to prevent the roots of the vegetables from rotting due to lack of oxygen, the common practice is to regularly replace the nutrient solution in the pool or trough. This method not only leads to a waste of nutrient solution, but also increases the workload of vegetable hydroponic cultivation. Utility Model Content

DETAILED DESCRIPTION

[0030] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0031] Example: See Figures 1 to 5The embodiment of the utility model provides a technical solution: an aeration water culture tray, comprising: a tray body 1, a partition 2, which is arranged in the tray body 1 and divides the inner cavity of the tray body 1 into an aeration zone 5 and a planting zone 6, and two drainage holes 20 are respectively provided at both ends of the partition 2 to connect the aeration zone 5 and the planting zone 6, one of the drainage holes 20 is used to pour the nutrient solution in the planting zone 6 into the aeration zone 5, and the other drainage hole 20 is used to introduce the nutrient solution in the aeration zone 5 into the planting zone 6; a rotating shaft 3, which is arranged in the aeration zone 5 and driven to rotate by a motor 16; a spiral blade 4, which is arranged on the outer wall of the rotating shaft 3 to promote the flow of the nutrient solution in the aeration zone 5; a rotary shaft 3 having a plurality of rotary shafts 3 and a plurality of rotary shafts 3, wherein the rotary shaft 3 has ... When the vegetable 17 of the above structure is grown in water, after adding nutrient solution into the tray body 1, the motor 16 drives the rotating shaft 3 and the spiral blade 4 to rotate, and the spiral blade 4 is used to drive the nutrient solution in the oxygenation zone 5 and the planting zone 6 to flow in a directional manner. This not only increases the oxygen capacity in the nutrient solution and prevents the vegetables 17 in the planting zone 6 from rotting due to lack of oxygen, but also allows the nutrient solution to circulate between the oxygenation zone 5 and the planting zone 6 to ensure that the vegetables 17 in the planting zone 6 evenly absorb the nutrients in the nutrient solution. Compared with the prior art method of preventing the root rot of the vegetables 17 by regularly replacing the nutrient solution, this can not only save nutrient solution but also reduce the workload of hydroponic planting of the vegetables 17.

[0032] On the basis of the above embodiment, in the present embodiment, a cover plate 7 is provided above the oxygenation zone 5, and the cover plate 7 can be closed at the top opening of the oxygenation zone 5. By setting the cover plate 7, the opening above the oxygenation zone 5 can be closed to prevent the rotating spiral blades 4 from bringing out the nutrient solution, and at the same time, the noise generated by the movement of the spiral blades 4 can be reduced.

[0033] On the basis of the above-mentioned embodiments, in the present embodiment, two ventilation pipes are provided at the two ends of the oxygenation zone 5, and the cover plate 7 and the disk body 1 are provided with semicircular notches which are adapted to the shape of the ventilation pipes. The ventilation pipes can increase the flow of air in the oxygenation zone 5 and the outside air, thereby ensuring that there is sufficient oxygen supply in the air in the oxygenation zone 5.

[0034] On the basis of the above-mentioned embodiments, the two ventilation pipes in this embodiment are respectively an intake pipe 10 and an exhaust pipe 11. A fan blade 14 is provided in the intake pipe 10. The fan blade 14 is rotatably connected to the intake pipe 10 through a connecting shaft 15. The connecting shaft 15 and the rotating shaft 3 are connected by a belt 13. The rotation of the fan blade 14 can further increase the flow of air in the oxygenation zone 5 and the outside air. Moreover, since the connecting shaft 15 connected to the fan blade 14 is coordinated with the rotating shaft 3 through the belt 13, when the motor 16 drives the rotating shaft 3 to rotate, it will also drive the fan blade 14 to rotate, which not only ensures the synchronization of the rotation of the fan blade 14 and the spiral blade 4, but also avoids the need to set up another driving device to drive the fan blade 14 to rotate.

[0035] On the basis of the above-mentioned embodiments, in this embodiment, the air inlet pipe 10 and the exhaust pipe 11 are both right-angled bends, and one end of the right-angled bend is arranged upward outside the oxygenation zone 5. By using right-angled bends for the air inlet pipe 10 and the exhaust pipe 11, the nutrient solution in the oxygenation zone 5 can be prevented from being discharged from the air inlet pipe 10 and the exhaust pipe 11 to the outside of the disk body 1 under the stirring of the spiral blades 4.

[0036] On the basis of the above-mentioned embodiment, in this embodiment, an oxygenation soft strip 12 made of a flexible material is provided on the spiral blade 4, and the oxygenation soft strip 12 is arranged along the length direction of the outer side of the spiral blade 4. By adding the oxygenation soft strip 12 to the spiral blade 4, the oxygenation soft strip 12 swings in the nutrient solution as the spiral blade 4 rotates, which can increase the splash in the oxygenation zone 5 and allow more oxygen to be incorporated into the nutrient solution. Among them, the oxygenation soft strip 12 is preferably a rubber strip.

[0037] On the basis of the above-mentioned embodiment, the present embodiment also includes a floating board 8 arranged in the planting area 6, and a plurality of planting holes 80 are evenly arranged on the floating board 8. A planting basket 9 with a hollow structure is inserted in the planting hole 80. The planting basket 9 is an existing structure, which is used to facilitate fixing the vegetables 17 in the planting hole 80. When planting the vegetables 17 in the planting basket 9, two stacked sponges can also be placed in the planting basket 9, and the seeds of the vegetable 17 can be sandwiched between the two sponges. The floating board 8 can use a foam board.

[0038] In order to further reduce the phenomenon of root rot of vegetables 17, on the basis of the above-mentioned embodiment, in this embodiment, a plurality of planting holes 80 are arranged at intervals on the floating plate 8, and an air flow channel 81 is opened on the floating plate 8 located below each row of planting holes 80, and ventilation holes 100 are opened on the disk body 1 at both ends of the air flow channel 81. When the floating plate 8 floats on the nutrient solution inside the disk body 1, the air flow channel 81 conducts air convection with the outside world through the ventilation holes 100. At this time, part of the roots of the vegetables 17 in the planting basket 9 can absorb oxygen in the air flowing through the air flow channel 81, thereby reducing the occurrence of root rot of the vegetables 17.

[0039] Working principle: Figure 5As shown, after the vegetable 17 water culture tray is placed horizontally, a proper amount of nutrient solution is added into the basin body. It is best if the nutrient solution submerges the lower half of the spiral blade 4. Then the motor 16 is connected to an external power source and started. The started motor 16 drives the rotating shaft 3, the spiral blade 4 and the oxygenation soft strip 12 to rotate. The spiral blade 4 drives the nutrient solution in the oxygenation zone 5 to flow. The nutrient solution in the oxygenation zone 5 and the nutrient solution in the planting zone 6 circulate through the drainage holes 20 on the partition 2. The flow can increase the oxygen capacity in the nutrient solution and prevent the vegetables 17 in the planting zone 6 from rotting due to lack of oxygen. At the same time, the circulation of the nutrient solution also ensures that the vegetables 17 in the planting zone 6 absorb the nutrient solution evenly. Compared with the prior art method of preventing root rot of vegetables 17 by regularly replacing the nutrient solution, the nutrients in the nutrient solution can not only save nutrient solution, but also reduce the workload of hydroponic planting of vegetables 17. While driving the rotating shaft 3 to rotate, the motor 16 will also drive the fan blades 14 to rotate. The rotating fan blades 14 can increase the air flow between the oxygenation zone 5 and the outside world to ensure that there is sufficient oxygen in the oxygenation zone 5. At the same time, the air flow channel 81 at the bottom of the floating plate 8 can exchange air with the outside world through the air vents 100, so that part of the roots of the vegetables 17 in the planting basket 9 can absorb the oxygen in the air flowing through the air flow channel 81, thereby further reducing the occurrence of root rot of vegetables 17.

[0040] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
