A kind of hydroponic device of adjustable liquid level
Technical field
The utility model belongs to growing vegetables technical field, is related to a kind of hydroponic device of adjustable liquid level.
Background technology
Water planting is the important planting type of modern agriculture.At present, water planting mode can be divided into according to Depth Nutrient Solution by deep liquid
Stream method and nutritional liquid membrane method, corresponding culture apparatus are not directed to the regulating device of liquid level.Crop is shorter in Seedling Stage root system,
It should not cultivate in the relatively low hydroponic device of liquid level.Some crop roots are more flourishing, cultivate in the higher hydroponic device of liquid level
Nutrient solution may be caused to overflow, be unfavorable for cultivation management.
Utility model content
In view of this, the utility model provides a kind of hydroponic device of adjustable liquid level, can be according to the difference of plant
The requirement of growth cycle, different root systems of plant to liquid stream, does liquid level corresponding adjusting.
Technical solution is used by the utility model:A kind of hydroponic device of adjustable liquid level, structure include support
Frame, water planting slot, upper hose, return pipe and liquid reserve tank.
Further, the liquid reserve tank is placed in supporting rack bottom, and water planting slot is placed in supporting rack higher level.
Further, the nutrition liquid bath water inlet of the water planting slot and water outlet connect upper hose and return pipe respectively, if
Only one layer of water planting slot, then upper hose and return pipe are respectively connected to bottom liquid reserve tank, wherein upper hose and diving in case still further below
Pump connection, return pipe are directly accessed by case lid in case.If there is at least two layers of water planting slot, the return pipe of higher level water planting slot connects
Enter the water inlet of next layer of water planting slot, the return pipe of lowermost layer water planting slot is accessed in liquid reserve tank again.
Further, the water planting slot water inlet is located at water planting groove sidewall top, and close to side wall upper limb, water outlet is located at water
Groove sidewall lower part is trained, close to water planting trench bottom.
Further, there is screw thread in " L " shape pipe one end tube wall on the inside of the water planting slot water outlet, it is long without screw thread one end
Degree is suitable with nutrient solution groove depth." L " the shape pipe is connect with the return pipe on the outside of water planting slot by a male elbow, and outer tooth is curved
Head screw socket is entered by water outlet fine jade inside water planting slot.
Further, rotatable 180 ° of threaded one end of " L " shape pipe, makes non-threaded end pipe mouth can reach from nutrition liquid bath
The arbitrary adjusting to liquid level is realized to each height at top in bottom.
The beneficial effects of the utility model are:Can battalion be adjusted according to the situation of the different stages of growth root system of plant
Nutrient solution height of liquid level, so as to achieve the effect that reasonable employment nutrient solution and the liquid oxygen content that has additional nutrients.

Attached drawing 2 is the enlarged drawing in A portions in Fig. 1;
Internal structure and its connected mode schematic diagram of the attached drawing 3 for the present embodiment " L " shape pipe at the middle and upper levels;
Attached drawing 4 is the internal structure and its connected mode schematic diagram of lower floor " L " shape pipe in the present embodiment.
Specific embodiment
Specific embodiment of the present utility model is further illustrated below in conjunction with the accompanying drawings:
Such as with reference to figure 1 and refering to what is shown in Fig. 2, a kind of hydroponic device of adjustable liquid level, structure include supporting rack 1, water
Slot 201 and 202, upper hose 3, return pipe 401 and 402 are trained, liquid reserve tank 5 has a liquid level regulator " L " in water planting slot 201 and 202
Shape pipe 61 and 62 can adjust nutrient solution height of liquid level according to the situation of the different stages of growth root system of plant.
Liquid reserve tank 5 is placed in 1 bottom of supporting rack, and water planting slot 201 and 202 is placed in 1 higher level of supporting rack.
201 water inlet 701 of upper strata water planting slot and water outlet 801 connect upper hose 3 and return pipe 401, return pipe 401 respectively
The water inlet 702 of next layer of water planting slot 202 is accessed downwards, and the return pipe 402 of next layer of water planting slot 202 is accessed again in liquid reserve tank 5.
201 and 202 water inlet 701 and 702 of water planting slot is located at side wall upper part, close to side wall upper limb, water outlet 801 and 802
Positioned at lower sidewall, close to 201 and 202 bottom of water planting slot.
There is screw thread in " L " the shape pipe 61 and 62 one end tube walls of 201 and 202 water outlet of water planting slot, 801 and 802 inside, be free of
Screw thread one end length is suitable with water planting groove depth.L " shapes pipe 61 and 62 passes through a male elbow 91 with the return pipe on the outside of water planting slot
With 92 connections.Such as with reference to figure 3 and refering to what is shown in Fig. 4, male elbow screw socket 911 and 912 screws in water by water outlet 801 and 802
It trains inside slot 201 and 202." L " shape pipe 61 and 62 has 611 and 621 rotatable 180 ° of screw thread one end, makes non-threaded end pipe mouth 612
It can reach each height from 201 and 202 bottom of water planting slot to top with 622.
According to raise crop root growth situation, two layers of 201 and 202 " L " shape pipe 61 and 62 of water planting slot is rotated, adjusts no spiral shell
Line end pipe mouth 612 and 622 is to required liquid level.10 power supply of immersible pump is connected, nutrient solution reaches top layer water planting by upper hose 3
201 water inlet 701 of slot simultaneously injects water planting slot 201.After liquid level reaches the non-threaded nozzle 612 of " L " shape pipe 61, nutrient solution overflows into
The non-threaded end pipe mouth 612 of " L " shape pipe 61, and pass through " L " shape pipe 61 and enter return pipe 401, then enter through lower floor's water planting slot 202
The mouth of a river 702 is flowed into lower floor's water planting slot 202.When 202 nutrient solution liquid level of lower floor's water planting slot reaches the non-threaded end of its " L " shape pipe 62
After nozzle 622, then overflow into " L " shape pipe 62 and pass through return pipe 402 and inject in liquid reserve tank 5.
