[0001] This utility model relates to the field of hydroponic vegetable cultivation, specifically to a device for growing head cabbage. Background Technology

[0002] Heading cabbage, also known as cabbage or head lettuce, is an important vegetable, highly adaptable, nutritious, and widely cultivated worldwide. With the development of hydroponics, more and more vegetables are being grown on a large scale; however, research on hydroponic cultivation of heading cabbage is relatively limited. Due to its large size, heading cabbage requires a large area for hydroponic cultivation research in the laboratory, limiting usable space and making it unsuitable for large-scale laboratory hydroponic research. Therefore, this paper proposes a growing device for heading cabbage suitable for laboratory use. Utility Model Content

One end of the connecting shaft is connected to the power system transmission to drive the turntable to rotate; Several hydroponic boxes are evenly distributed along the circumference between the two turntables. Each hydroponic box has a connector at both ends, which is connected to an L-shaped connecting rod. The ends of the connecting rods are rotatably mounted on the bearing base of the turntable.

[0005] Furthermore, a nutrient solution distribution tank is fitted at one end of the connecting shaft. The distribution tank has an annular structure, and the connecting shaft has a hollow tube structure. A water supply pipe connected to the distribution tank is installed inside the connecting shaft. The water supply pipe extends out of one end of the connecting shaft and is connected to a water pipe rotary joint at the end of the connecting shaft.

[0014] The specific embodiments of this utility model are described below to enable those skilled in the art to understand this utility model. However, it should be understood that this utility model is not limited to the scope of the specific embodiments. For those skilled in the art, as long as various changes are within the spirit and scope of this utility model as defined and determined by the appended claims, these changes are obvious. All utility model creations utilizing the concept of this utility model are within the scope of protection.

[0015] like Figure 1 and Figure 2 As shown, a cabbage planting device includes a base 1, with two turntables 7 arranged above the base 1. The two turntables 7 are coaxially connected by a connecting shaft 9. The two ends of the connecting shaft 9 are rotatably mounted on bearing seats, which are fixed to the base 1 by a bracket.

[0016] One end of the connecting shaft 9 is connected to the power system for driving the turntable 7 to rotate; a bearing is installed in the bearing housing so that the turntable 7 can rotate freely under the drive of the drive motor 3.

[0017] Several hydroponic boxes 17 are evenly distributed along the circumference between the two turntables 7. Each hydroponic box 17 has a connector at both ends, which are connected to an L-shaped connecting rod 8. The ends of the connecting rod 8 are rotatably mounted on the bearing base of the turntable 7. The hinged design between the connecting rod 8 and the turntable 7 ensures that the hydroponic box 17 always faces upwards under gravity and will not tip over during rotation.

[0018] This solution utilizes the vertical space of a laboratory to achieve hydroponic cultivation. It is also suitable for large-scale cabbage cultivation in greenhouses, effectively increasing the quantity of cabbage grown and improving space utilization. Multiple hydroponic boxes 17 are installed on a rotating turntable 7. When harvesting or observing the growth of the cabbage, the drive motor 3 rotates the turntable 7, bringing the target hydroponic box 17 to the bottom. This facilitates operation and observation by staff and allows for easy placement of cabbage seedlings, enabling hydroponic cultivation of cabbage at different growth stages.

[0019] In this embodiment, a nutrient solution distribution tank 12 is fitted at one end of the connecting shaft 9. The distribution tank 12 has an annular box structure, and the connecting shaft 9 has a hollow tube structure. A water supply pipe 19 that communicates with the distribution tank 12 is installed inside the connecting shaft 9. The water supply pipe 19 extends out of one end of the connecting shaft 9 and is connected to a water pipe rotary joint 13 at the end of the connecting shaft 9. The water pipe rotary joint 13 is connected to the nutrient solution supply system.

[0020] The water tank 12 has several joints 18 arranged axially, and spring water pipes 11 are connected to the joints 18. The end of the spring water pipes 11 is connected to the water inlet 10 provided on one side of the hydroponic tank 17.

[0021] In this embodiment, the nutrient solution supply system includes a nutrient solution storage tank 16 installed on the base 1. A water pump 15 for drawing nutrient solution is installed at the upper end of the nutrient solution storage tank 16. The water pump 15 is connected to the water pipe rotary joint 13 through a water pipe 14.

[0022] The nutrient solution in the nutrient solution storage tank 16 is first pumped into the water distribution tank 12 by the water pump 15, and then the nutrient solution is sent to different hydroponic tanks 17 through the water distribution tank 12. When supplying the solution, the water distribution tank 12 needs to be filled first, and then the solution is discharged into the hydroponic tank 17. The spring water pipe 11 can be bent and extended, and there will be no pulling during the rotation of the hydroponic tank 17.

[0023] In this embodiment, a water outlet 6 is provided on the other side of the hydroponic box 17. The position of the water outlet 6 is lower than that of the water inlet 10. Both the water outlet 6 and the water inlet 10 are equipped with valves. A waste liquid tank 2 is provided at the upper end of the base 1. The waste liquid discharged from the water outlet 6 is discharged into the waste liquid tank 2.

[0024] The nutrient solution supply system automatically supplies nutrient solution to different hydroponic tanks 17, and automatically discharges the waste nutrient solution, achieving automated nutrient supply. When drainage is needed, the target hydroponic tank 17 is rotated to the bottom, and the valve on the outlet 6 is opened, and the waste solution is automatically discharged into the waste solution tank 2. The waste solution tank 2 can be connected to the sewage pipe 14 for discharge, or connected to a sewage treatment device for purification and recycling.

[0025] In this embodiment, the bottom of the hydroponic box 17 is set as a slope, with the highest point of the slope located on the side of the inlet 10 and the lowest point located on the side of the outlet 6. The slope design facilitates the discharge of waste liquid. The power system includes a driven gear 5 located at the end of the connecting shaft 9. The driven gear 5 meshes with the driving gear 4. The driven gear 5 is connected to the drive motor 3 through a reducer. The drive motor 3 and the reducer are mounted on the base 1.

[0026] In this embodiment, the drive motor 3, water pump 15 and valve are all connected to the controller of the device. The controller is equipped with a PCB board with a C51 microcontroller, and the controller is used to control each electrical component.

[0027] This embodiment can also be applied to the planting process of soil-grown head cabbage, and is also suitable for greenhouse planting. Before planting, the soil is added to the hydroponic box 17. After the head cabbage seedlings are planted, the water pump 15 delivers nutrient solution to the soil at regular intervals to realize the automatic addition of nutrient solution to the head cabbage.
