Description

Technical Field

[0001] The utility model relates to the technical field of irrigation equipment, in particular to a citrus seedling water and fertilizer tidal irrigation equipment. Background Art

[0002] Tidal irrigation equipment is designed for the cultivation of potted plants with nutrient solution. The pot is placed on the cultivation bed, and the nutrient solution is sent from the storage barrel to the cultivation bed, submerging the cultivation bed to a depth of about 2-3 cm. After about 10-15 minutes, the nutrient solution rises to the surface of the medium in the pot due to capillary action. At this time, the nutrient solution is discharged and flows back to the storage barrel again. The nutrient solution will be sent out when another cultivation bed needs water.

[0003] Tidal irrigation equipment can form a water-saving, efficient, and completely closed system cycle, which can achieve a utilization rate of 90%, and the plant growth rate is faster. The weekly seedling age can be one day earlier than the traditional seedling method, which improves the utilization rate of the facility. However, plant growth needs to be maintained at a certain temperature to achieve a higher growth rate. The existing tidal irrigation equipment only realizes tidal irrigation and cannot provide a certain temperature for the plant growth environment. Especially in winter, irrigation with cold water and fertilizer still cannot increase the plant growth rate; in addition, the existing tidal irrigation equipment often causes poor reflux due to debris accumulated in the reflux pipe.

A return pipe is provided at the bottom of the cultivation bed, one end of the return pipe is connected to the inner bottom of the cultivation bed by a three-way head, and the other end is connected to the storage box. The first water pump draws water and fertilizer from the storage box to the cultivation bed, and the water and fertilizer return to the storage box through the return pipe. The discharge port of the second water pump is connected to the three-way head by a water injection pipe, and water is pumped from an external water pool into the return pipe to flush the return pipe. An L-shaped stainless steel pipe connected to the first water pump is provided on one side of the cultivation bed, and an electric heating plate is provided on the outer wall of the L-shaped stainless steel pipe to heat the water and fertilizer flowing through the L-shaped stainless steel pipe.

[0019] Embodiment 1

[0020] The utility model heats the water and fertilizer flowing through the L-shaped stainless steel pipe by setting an electric heating plate, and injects the warm water and fertilizer into the cultivation bed. The water and fertilizer provide nutrients and can adjust and maintain the temperature of the plant growth environment, thereby increasing the plant growth rate. In addition, the second water pump can pump high-pressure water to flush the return pipe to avoid blockage of the return pipe.

[0021] like Figure 1 As shown, a citrus seedling water and fertilizer tidal irrigation equipment includes a cultivation bed 1, a storage box 2, a first water pump 3 and a second water pump 4. A return pipe 11 is provided at the bottom of the cultivation bed 1. One end of the return pipe 11 is connected to the inner bottom of the cultivation bed 1 by a tee, and the other end is connected to the storage box 2. The first water pump 3 draws water and fertilizer from the storage box 2 to the cultivation bed 1, and the water and fertilizer flow back to the storage box 2 through the return pipe 11. The drainage port of the second water pump 4 is connected to the tee by a water injection pipe 41, and water is pumped from the external water pool into the return pipe 11 to flush the return pipe 11. An L-shaped stainless steel pipe 12 connected to the first water pump 3 is provided on one side of the cultivation bed 1, and an electric heating plate 121 is provided on the outer wall of the L-shaped stainless steel pipe 12 to heat the water and fertilizer flowing through the L-shaped stainless steel pipe 12. The storage box 2 may also be provided with a water pipe connected to the outside for introducing water and fertilizer, or the water and fertilizer outside may be pumped into the storage box 2 for storage through the second water pump 4 .

[0022] It should be noted that the first water pump 3, the second water pump 4, the electric heating plate 121 and the first solenoid valve 131 and the second solenoid valve 411 described below can be controlled on and off and switched by an external control system, or a single switch can be set to connect to an external power supply and manually controlled by staff.

[0023] Furthermore, a drainage pipe 13 connected to a three-way connector is provided at the bottom of the cultivation bed 1, and a first electromagnetic valve 131 is provided on the drainage pipe 13. The first electromagnetic valve 131 can be connected to an external power supply and a controller via a cable to facilitate control of drainage time.

[0024] Furthermore, a partition 14 is provided on the cultivation bed 1, and a plurality of planting grooves 141 for cultivating citrus seedlings are provided on the partition 14. The bottom of the planting groove 141 is close to the inner bottom of the cultivation bed 1, and is provided with through holes, and water and fertilizer penetrate into the planting groove 141 through the through holes.

[0025] Furthermore, one end of the L-shaped stainless steel pipe 12 extends below the partition 14, in order to prevent the water and fertilizer from being exposed to the outside of the cultivation bed 1 as much as possible, reduce odor volatilization and temperature loss, avoid the odor of the water and fertilizer causing an unfavorable environment atmosphere, and help maintain the growth environment temperature of citrus seedlings. A plurality of support rods are provided at the bottom of the partition 14 for supporting the partition 14 above the cultivation bed 1.

[0026] Further, one end of the return pipe 11 is located at the inner upper part of the storage box 2. It is prevented that the water and fertilizer in the storage box 2 enter the return pipe 11, resulting in the water and fertilizer on the cultivation bed 1 cannot be discharged, and the function of tidal irrigation cannot be achieved.

[0027] Furthermore, a plurality of columns 15 are provided at the bottom of the cultivation bed 1 for supporting the cultivation bed 1 .

[0028] Furthermore, a second solenoid valve 411 is provided on the water injection pipe 41 .

[0029] Working principle:

[0030] Start the first water pump 3 and energize the electric heating plate 121, draw water and fertilizer from the storage box 2 to the cultivation bed 1, and the electric heating plate 121 heats the water and fertilizer when passing through the L-shaped stainless steel pipe 12. When the water and fertilizer reach a certain height at the bottom of the inner side of the cultivation bed 1, they penetrate into the planting trough 141 through the through holes at the bottom of the planting trough 141 for absorption by the roots of the citrus seedlings. After the water and fertilizer are injected into the cultivation bed 1 for a period of time, the first water pump 3 is paused and the electric heating plate 121 is powered off, the first solenoid valve 131 is energized and controlled to open the valve, and the water and fertilizer on the cultivation bed 1 enter the return pipe 11 from the drain pipe 13, and the return pipe 11 guides the water and fertilizer into the storage box 2, thereby completing a tidal irrigation process. During the tidal irrigation process, the second solenoid valve 411 remains closed to prevent the refluxed water and fertilizer from entering the water injection pipe 41.

[0031] After the device is used for a period of time, it is usually necessary to flush the return pipe 11. During the flushing process, the first solenoid valve 131 remains closed, the second solenoid valve 411 remains open, and the second water pump 4 is started to pump external clean water into the return pipe 11. The high-pressure clean water flushes the inner wall of the return pipe 11 to avoid blockage.
