Description

Technical Field

[0001] The utility model relates to the technical field of cotton, and particularly relates to a cotton hydroponic device. Background Art

[0002] With the development of the agricultural field, it is necessary to conduct certain research and cultivation on crops. However, since cotton is a cotyledon-emerging crop, it cannot be directly hydroponically cultivated. It needs to be cultivated in a substrate first and then transferred to a nutrient solution after the cotyledons emerge.

[0003] For example, Chinese Patent No. CN212344864U proposes a cotton hydroponic device. This patent realizes the cultivation method of first substrate cultivation and then hydroponics by simultaneously installing a soil cultivation dish and a hydroponic dish in the chassis. Utilizing the characteristic of moving up and down on the surface of the sliding column, the cotton cultivated in soil is lifted upward, the root hairs are cleaned with a brush, and then the cover plate is rotated to place it above the hydroponic dish, and then slid downward so that the root hairs are immersed in the nutrient solution for hydroponics. Since both the soil cultivation dish and the hydroponic dish are placed in the chassis, the functions of flexible soil replacement or water replacement can be realized to ensure the cultivation quality. This device can transplant cotton seedlings closely and simply, ensuring that the cotton seedlings are not damaged. This application designs a cotton hydroponic device that can protect the cotton seedlings from root damage during transplantation and can cultivate a large number of cotton seedlings. However, in this scheme, when the above device hydroponically cultivates cotton, the cotton needs to be removed from the soil cultivation dish. Since a large amount of soil still adheres to the roots of the cotton, it is necessary for the staff to wash it clean with a large amount of water and then put it into the hydroponic dish to prevent the soil from entering the hydroponic dish and affecting the sterile environment therein. When the above device cleans the roots of the cotton, it may be necessary for the staff to pull out the cotton from the inside of the limit hole, wash it clean and then put it back into the limit hole. Then, when pulling out the cotton seedlings, their roots are relatively developed, and the cotton seedlings may be damaged during extraction. At the same time, as the cotton seedlings grow continuously, the cotton will grow larger, and then it is necessary to adjust the distance between the cotton plants. It is necessary to pull out the cotton from the inside of the limit hole again, which may cause damage to the roots again, thus possibly affecting the subsequent growth of the cotton. Summary of the Utility Model

[0004] In view of the deficiencies of the prior art, the present utility model provides a cotton hydroponic device, which solves the problem that when the above device hydroponics cotton, the cotton needs to be removed from the soil culture dish.

The inner wall surface of the first threaded hole 29 is threadedly connected with a first threaded column 30, and the outer wall surface of the first threaded column 30 is movably sleeved with the inner wall surface of the connecting groove 31. By providing the first threaded column 30, after the staff adjusts the distance between the two first connecting blocks 4, the first threaded column 30 is screwed into the first threaded hole 29 and the connecting groove 31, so as to facilitate the limiting of the first connecting block 4. A plurality of second limiting holes 28 are provided on the outer wall surface of the limiting column 27, and a second threaded hole 37 is provided on the top surface of the second clamping plate 21.

A handle 35 is fixedly installed on the top surface of the baffle 33.

[0026] Working principle: Please refer to Figures 1-6As shown, when cultivating cotton seedlings, through the provided placement bin 1, the staff first inject a large amount of nutrient solution into the interior of the placement bin 1. Then, the staff pick up the cleaned cotton seedlings. The staff will press the clamping post 13. After the clamping post 13 enters the interior of the first positioning groove 11, the staff will pull the first connecting block 4. Then, after the first connecting block 4 drives the first clamping plate 17 to move, the first clamping plate 17 and the second clamping plate 21 will separate. After the staff place the cotton seedlings into the interior of the second placement hole 22, they will then adjust the distance between the second clamping plate 21 and the first clamping plate 17. At this time, the staff push the first connecting block 4, and then the positioning post 20 enters the interior of the second positioning groove 23, and at the same time, the clamping block 10 enters the interior of the limiting groove 15. The staff adjust the gap between the second placement hole 22 and the first placement hole 18 according to the diameter of the cotton seedlings. Then, the spring 12 rebounds to drive the clamping post 13 into the interior of the clamping hole 14, thereby limiting the positions of the first connecting block 4 and the second connecting block 5. As the cotton seedlings continue to grow, the diameter of the roots of the cotton seedlings is constantly increasing. The staff press the clamping post 13, then pull the first connecting block 4 to adjust the distance between the second placement hole 22 and the first placement hole 18, and then let the clamping post 13 enter the corresponding clamping hole 14 for limiting. At this time, as the roots of the cotton seedlings continue to grow, the roots of the two cotton seedlings will entangle together. The staff push the second clamping plate 21, and then the second clamping plate 21 drives the cotton seedlings of the first clamping plate 17 to move to adjust the position between the two cottons horizontally. At the same time, the staff will pull the first connecting block 4 to drive the position of a whole row of cotton seedlings and adjust the distance between the cotton seedlings in the whole row, so as to achieve the effect of adjusting the distance between the cotton seedlings.

[0027] Through the provided first threaded post 30, after the staff adjust the distance between the two first connecting blocks 4, they screw the first threaded post 30 into the interior of the first threaded hole 29 and the connecting groove 31, so as to facilitate the limitation of the first connecting block 4. Through the provided second threaded post 36, after the staff adjust the distance between the two cotton seedlings, the staff screw the second threaded post 36 into the interior of the second limiting hole 28 and the second threaded hole 37, so as to limit the second clamping plate 21. Through the provided baffle 33, when cultivating cotton seedlings, when the cotton seedlings are relatively small, the staff concentrate the seedlings on one side of the placement bin 1, and then insert the baffle 33 into the placement groove 32 close to the cotton. Then, nutrient solution is placed into the interior of the placement bin 1. Then, by changing the position of the baffle 33, the space size inside the placement bin 1 is adjusted, so as to adjust the volume of the nutrient solution according to the growth of the seedlings, which is convenient for saving the nutrient solution.
