AI Technical Summary
In column-type matrix cultivation, the supply of nutrient solution is uneven, especially due to the arrangement of the column, the lower substrate is under a large pressure, which leads to a large amount of nutrient solution flowing out during watering, resulting in uneven supply of nutrient solution.
A nutrient solution supply device for column-type matrix cultivation is designed. By setting up a main liquid tank, float ball, breathable hole, liquid reservoir plate and interlaced liquid inlet and liquid outlet on the column, the filling and transfer of nutrient solution are controlled by using float balls, and the rotation of the liquid reservoir plate is combined to achieve quantitative supply, ensuring the uniform dose of nutrient solution in each matrix basin.
The precise balanced supply of nutrient solution is achieved, ensuring the same dose of nutrient solution in each matrix basin, and improving the utilization rate of planting space and the uniformity of the liquid supply.

Description
Technical Field
[0001] The utility model relates to the technical field of soilless cultivation, in particular to a nutrient solution supply device for columnar substrate cultivation. Background Technique
[0002] Soilless cultivation refers to a cultivation method in which plants are fixed with media such as water, peat, forest leaf mold, vermiculite, etc. as the substrates of the plant roots, and the plant roots can directly contact the nutrient solution. In soilless cultivation, the components of the nutrient solution are easy to control and can be adjusted at any time. In places where light and temperature are suitable and there is no soil, such as deserts, beaches, and deserted islands, as long as there is a certain amount of fresh water supply, it can be carried out.
[0003] The characteristics of substrate cultivation are that the roots of cultivated crops are fixed by the substrate. It fixes the roots of crops in organic or inorganic substrates. Organic substrates include peat, rice husks, tree bark, etc., and inorganic ones such as vermiculite, perlite, rock wool, ceramsite, gravel, sponge soil, etc. can all be used as support media. The nutrient solution is supplied to the crops by means of drip irrigation or trickle irrigation. The existing planting method using columnar substrate cultivation can effectively improve the utilization rate of planting space through vertical cultivation.
[0004] However, when supplementing the nutrient solution for columnar substrate cultivation, due to the height difference between each planting surface caused by the setting of the columns, the substrate at the lower part has a greater pressure on the supply pipe, resulting in more nutrient solution flowing out during irrigation, causing the defect of uneven nutrient solution supply.
[0005] Based on this, the utility model designs a nutrient solution supply device for columnar substrate cultivation to solve the above problems. Summary of the Utility Model

[0031] A nutrient solution supply device for column-type substrate cultivation comprises a mounting base 1.
[0032] A column 2 is fixedly arranged on the mounting base 1, and the column 2 includes an inner tube 3 and an outer tube 4; a main liquid supply pipe 5 is fixedly arranged on the inner tube 3, and a main liquid tank 6 is provided on the inner tube 3, and a float 7 is placed in the main liquid tank 6; an air hole 8 is provided on the outer tube 4, and the cross-sectional area of the float 7 is larger than the cross-sectional area of the air hole 8; a dustproof net 9 is fixedly arranged on the air hole 8; and a make way groove 10 is provided on the outer tube 4.
[0033] The inner tube 3 is fixedly arranged on the mounting base 1, a positioning block 11 is fixedly arranged on the inner tube 3, a positioning hole 12 corresponding to the positioning block 11 is opened on the outer tube 4, a threaded hole 13 is opened on the positioning block 11, a through hole 14 is opened on the positioning hole 12, a mounting bolt 15 is threadedly connected to the threaded hole 13, and the mounting bolt 15 passes through the through hole 14 to press the outer tube 4 against the inner tube 3; a sealing pad 16 is placed between the inner tube 3 and the outer tube 4.
[0034] A placement groove 17 is provided on the column 2, and the placement groove 17 is located between the inner tube 3 and the outer tube 4; a matrix basin 18 is fixedly provided on the side of the outer tube 4 located outside the placement groove 17, and a liquid outlet 19 is provided on the matrix basin 18; a liquid inlet 20 is provided on the side of the outer tube 4 located inside the placement groove 17, and the liquid outlet 19 and the liquid inlet 20 are arranged alternately; a liquid storage plate 21 is rotatably provided in the placement groove 17, and a liquid storage cavity 22 is provided on the liquid storage plate 21; a handle 23 is fixedly provided on the liquid storage plate 21, and the handle 23 is slidably provided in the yielding groove 10, and four handles 23 are provided.
[0035] The liquid inlet 20, the liquid storage cavity 22 and the liquid outlet 19 are arranged in groups, and there are multiple groups of the liquid inlet 20, the liquid storage cavity 22 and the liquid outlet 19.
[0036] The implementation principle of this embodiment is as follows: When assembling the column 2, first sleeved the liquid storage plate 21 on the inner tube 3, aligning the liquid storage cavity 22 with the liquid inlet 20 to avoid dislocation between the two. Then place the sealing gasket 16 on the inner tube 3. Finally, sleeve the outer tube 4 on the inner tube 3. After aligning the positioning hole 12 with the positioning block 11, fix the outer tube 4 on the inner tube 3 through the mounting bolt 15. The two squeeze the sealing gasket 16 to keep the main liquid tank 6 in good sealing effect, thus completing the assembly of the column 2. When in use, plant crops in the substrate basin 18, connect the nutrient solution supply pipe to the main liquid supply pipe 5, so that the main liquid tank 6 is filled with nutrient solution. The nutrient solution causes the float ball 7 in the main liquid tank 6 to rise until the float ball 7 blocks the ventilation hole 8, then stop filling the nutrient solution. When supply is needed, rotate the liquid storage plate 21 to align the liquid storage cavity 22 with the liquid inlet 20. At this time, the nutrient solution in the main liquid tank 6 fills into the liquid storage cavity 22 through the liquid inlet 20. Then rotate the liquid storage plate 21 to align the liquid storage cavity 22 with the liquid outlet 19. At this time, the nutrient solution in the liquid storage cavity 22 flows into the substrate basin 18 through the liquid outlet 19, completing the supply operation of the nutrient solution in Yancheng, and ensuring that the dosage of the nutrient solution in each substrate basin 18 is the same.
[0037] Connect the main liquid pipe to the nutrient solution supply pipe. The nutrient solution fills into the main liquid tank 6, causing the float ball 7 to float until the main liquid tank 6 is full when the float ball 7 blocks the ventilation hole 8. When supply is needed, rotate the liquid storage plate 21 to make the liquid storage cavity 22 move between the liquid inlet 20 and the liquid outlet 19, quantitatively transferring the nutrient solution in the main liquid tank 6 to the substrate basin 18, completing the operation of nutrient solution supply, and having the advantage of accurately balancing the added dosage in each substrate basin 18.
