DETAILED DESCRIPTION

[0053] The present invention is further described in detail below through embodiments. The embodiments are only used to illustrate the present invention and do not limit the scope of the present invention.

[0054] A soilless cultivation device for potato seedlings, comprising:

[0055] The pool 100 is a rectangular parallelepiped structure with an opening at the top;

[0056] The box body 200 has a main cross-section of an inverted isosceles trapezoidal hollow structure, and its bottom is arranged on the upper part of the pool 100. There are several boxes 200 and they are arranged side by side. The nutrient solution mist in the box body 200 gradually accumulates in the box body 200 and forms larger water droplets. The water droplets can flow downward out of the box body 200 and enter the pool 100, and then be accumulated and collected through the pool 100 (this process will not be repeated). The "wide at the top and narrow at the bottom" structure of the box body 200 is conducive to the accumulation of nutrient solution mist in a larger space at the top, thereby facilitating the growth of potato seedlings located at the top.

[0057] There are several planting grooves 300, which are located on the upper part of the box body 200. The planting grooves 300 are placed on the upper part of the box body 200. At this time, the planting grooves 300 are detachable relative to the box body 200. The planting grooves 300 are connected to the box body 200. When the planting grooves 300 are placed on the upper part of the box body 200, the position of the planting grooves 300 relative to the box body 200 can be rotated and adjusted. The planting grooves 300 are used for transplanting and cultivating potato seedlings. The potato seedlings achieve stable "contact" with the box body 200 through the planting grooves 300, and the roots at the bottom of the potato seedlings can contact with the nutrient solution water mist in the box body 200, thereby achieving the growth of the potato seedlings; planting When the groove 300 is placed on the upper part of the box body 200, as the potato seedlings grow, the planting grooves 300 at different positions can be adjusted and interchanged according to the growth differences of the potato seedlings in different planting grooves 300, or the same planting groove 300 can be rotated and adjusted, so that the position of the potato seedlings in the planting groove 300 relative to the box body 200 can be changed, which is more conducive to the growth of the potato seedlings; that is, the planting groove 300 can be shifted as a whole relative to the box body 200, at which time the positions of different planting grooves 300 can be interchanged, and at the same time, a single planting groove 300 can be rotated relative to the box body 200.

[0058] The sprayer 400 is located in the box 200 and sprays nutrient solution mist upward; the external nutrient solution is "sprayed" into the box 200 through the sprayer 400 and diffused into the box 200. At this time, the nutrient solution mist in the box 200 is absorbed by the potato seedlings in the planting groove 300.

[0059] By planting the potato seedlings in the planting groove 300, and then diffusing the nutrient solution mist in the box 200 through the sprayer 400, the potato seedlings absorb nutrients through the nutrient solution mist in the box 200. Because the concentration of the nutrient solution mist at different positions in the box 200 is different, as time goes by, according to the growth of the potato seedlings (especially the growth of the roots), the position of the planting groove 300 relative to the box 200 is fine-tuned (rotated or replaced) to make the growth of the potato seedlings more uniform.

[0060] See also Figure 3-Figure 6 , the box 200 includes:

[0061] The bottom plate 210 is a rectangular plate structure, which is horizontally arranged;

[0062] The front side plate 220 is a rectangular plate structure, which is fixed to the front edge of the bottom plate 210, and the front side plate 220 is inclined;

[0063] The rear side plate 230 is a rectangular plate structure, which is fixed to the rear edge of the bottom plate 210. The rear side plate 230 is inclined and symmetrically arranged with the front side plate 220.

[0064] The left side plate 240 is an isosceles trapezoidal plate structure, which is vertically fixed to the left side of the bottom plate 210, the front side plate 220 and the rear side plate 230;

[0065] The right side plate 250 is an isosceles trapezoidal plate structure, which is vertically fixed to the right side of the bottom plate 210, the front side plate 220 and the rear side plate 230;

[0066] The cover plate 260 is fixed to the upper parts of the front side plate 220, the rear side plate 230, the left side plate 240 and the right side plate 250, and the downward projection of the cover plate 260 covers the bottom plate 210;

[0067] The right side plate 250, the cover plate 260 and the left side plate 240 are provided with slots 261, the cross section of the slots 261 is in the shape of "︶", the slots 261 extend from the right end of the cover plate 260 to the left end of the cover plate 260, and the number of slots 261 is several and they are arranged side by side on the cover plate 260; the planting grooves 300 can be matched and placed in the slots 261, at this time, the planting grooves 300 are equivalent to being embedded in the slots 261, so that the planting grooves 300 can be stabilized relative to the box body 200 and it is also convenient to At a later stage, the planting grooves 300 at different positions are interchanged. At the same time, because the planting grooves 300 are placed in the slot holes 261, they can be "rotated" in the slot holes 261. At this time, the position of a single planting groove 300 relative to the box body 200 changes, so that the position of the roots of the potato seedlings in the planting grooves 300 relative to the box body 200 changes, thereby the growth of the potato seedlings in the single planting grooves 300 can be monitored without replacing the planting grooves 300.

[0068] The water guide plate 500 is arranged inside the box 200, and the water guide plate 500 is symmetrically arranged along the front and rear sides of the box 200. The water guide plate 500 is used to change the internal structure of the box 200, so that the inside of the box 200 is formed into a shape that is wide at the top and narrow at the bottom, which is more conducive to the diffusion of nutrient solution mist from bottom to top into the entire box 200, thereby being more conducive to the absorption of potato seedlings in the planting groove 300.

[0069] See also Figure 4 , 5 , the water guide plate 500 comprises:

[0070] The water guide plate 510 has a "︵"-shaped cross section. The water guide plate 510 is fixed to the inner side of the front side plate 220. The upper end of the water guide plate 510 coincides with the upper end of the front side plate 220. The water guide plate 510 extends from the front end to the rear end of the front side plate 220.

[0071] The water guide plate 520 has a "︵"-shaped cross section. The water guide plate 520 is fixed to the inner side of the rear side plate 230. The upper end of the water guide plate 520 coincides with the upper end of the rear side plate 230. The water guide plate 520 extends from the front end to the rear end of the rear side plate 230. The water guide plate 1 510 and the water guide plate 520 have the same structure and are symmetrically arranged.

[0072] A water mist channel 530 is formed between the water guide plate 1 510 and the water guide plate 2 520. The water mist channel 530 is in the shape of a trumpet opening, and the upper opening size is larger than the lower opening size. The trumpet-shaped structure of the water mist channel 530 is conducive to the movement of the nutrient solution mist from bottom to top and diffusion into the entire box body 200. At the same time, the nozzle 430 is located at the upper part of the nutrient solution mist channel 530, which is conducive to the diffusion of the nutrient solution mist in the upper part of the water mist channel 530 while preventing a large amount of nutrient solution mist from entering the lower part of the water mist channel 530.

[0073] A water outlet hole 211 is formed through the middle of the bottom plate 210 and is a rectangular structure. The nutrient solution mist entering the water mist channel 530 diffuses in the water mist channel 530 , and a portion of the nutrient solution mist moves downward through the water mist channel 530 to form water droplets and is finally discharged through the water outlet hole 211 .

[0074] The planting trough 300 comprises:

[0075] The groove plate 310 has an arc-shaped cross section, and the length of the groove plate 310 is slightly greater than the length of the cover plate 260;

[0076] The spacer block 320 has a semicircular cross section and a planar upper portion. The spacer block 320 extends from one end of the slot plate 310 to the other end.

[0077] The positioning pendulum 330 is located at both ends of the cushion block 320, and the positioning pendulum 330 is rotatable relative to the cushion block 320;

[0078] A plurality of planting holes 340 are arranged through the planting groove 300 and are arranged side by side in the planting groove 300 . The planting holes 340 pass through the pad 320 and the groove plate 310 at the same time. The planting holes 340 are used for inserting potato seedlings (planting baskets or sponges) to fix the potato seedlings (planting baskets or sponges), and the roots of the potato seedlings are oriented toward the box body 200 .

[0079] Preferably, shafts 321 are fixed on both sides of the cushion block 320, and the shafts 321 protrude from the end surface of the cushion block 320;

[0080] The main body of the positioning pendulum 330 is a fan-shaped structure, and a through hole 331 is provided on the upper part thereof. The through hole 331 is matched with the shaft rod 321 and the shaft rod 321 can pass through the through hole 331. At this time, the positioning pendulum 330 can rotate relative to the shaft rod 321 and the cushion block 320, and finally the positioning pendulum 330 is in a stable state of vertical downward; when the state of the positioning pendulum 330 is stable, the positioning pendulum 330 can fix the planting groove 300 from both sides of the planting groove 300 to prevent the planting groove 300 from shifting. The positioning pendulum 330 has a certain weight, and its material can be selected from metals such as iron.

[0081] Fig.11 Preferably, a head 322 is fixed at the end of the shaft rod 321. The head 322 is a circular plate structure, and the diameter of the head 322 is larger than the diameter of the shaft rod 321. The head 322 is used to prevent the positioning pendulum 330 from detaching from the shaft rod 321.

[0082] like Figure 1 As shown, when the planting groove 300 is rotated, the positioning pendulum 330 is still in a vertical downward state. When the position of the planting groove 300 is stabilized, the positioning pendulum 330 can still provide downward "pulling force" to both ends of the planting groove 300, thereby facilitating the stability of the position of the planting groove 300.

[0083] The nebulizer 400 comprises:

[0084] The water delivery pipe 410 is a circular tubular structure, which is arranged horizontally from right to left.

[0085] The vertical pipe 420 is fixed on the water pipe 410. The vertical pipe 420 is vertically arranged from bottom to top. There are a plurality of vertical pipes 420 and they are arranged side by side along the water pipe 410. The vertical pipe 420 is connected to the water pipe 410.

[0086] The nozzle 430 is fixed at the upper part of the vertical pipe 420. The water in the water pipe 410 is transported upward to the nozzle 430 through the vertical pipe 420, and then sprayed upward by the nozzle 430 and diffused into the box 200. The nozzle 430 is located at the upper part of the water mist channel 530. At this time, the water mist sprayed by the nozzle 430 is mainly concentrated in the upper part of the water mist channel 530, which is more conducive to the nutrient solution mist to gather at the lower part of the planting groove 300, thereby facilitating the root system of the potato seedlings to absorb the nutrient solution mist;

[0087] The water delivery pipe 410 is connected to the main pipe 440, which is located at the lower right side of the box body 200 and is arranged longitudinally;

[0088] Preferably, sliders 280 are fixed on both sides of the lower part of the box body 200, and the sliders 280 are rectangular block structures;

[0089] On both sides of the upper part of the water tank 100, sliding grooves 110 are opened. The cross-section of the sliding groove 110 is in a "U" shape, and the sliding groove 110 extends from the front side to the rear side of the water tank 100; when the box body 200 is placed on the water tank 100, the sliding block 280 is correspondingly arranged in the sliding groove 110. At this time, the box body 200 can move forward or backward relative to the water tank 100, and a baffle plate 120 can be arranged between adjacent box bodies 200; an insertion gap 221 is formed between adjacent baffle plates 120, and the box body 200 is inserted downward into the insertion gap 221;

[0090] When in use, place the lower parts of at least two boxes 200 on the pool 100, the slider 280 at the lower part of the box 200 is matched and arranged in the slide 110, the water outlet 211 of the box 200 is facing the pool 100, adjust the box 200 to move to a suitable position, and then set the shielding plate 120 between the adjacent boxes 200, then connect the water pipe 410 with the main pipe 440, and place the planting groove 300 in the slot hole 261. At this time, the central axis of the planting groove 300 coincides with the central axis of the slot hole 261, and the positioning pendulum 330 is in a natural vertical state. The positioning pendulum 330 provides a certain The downward "pulling force" is conducive to the stability of the planting groove 300. The potato seedlings are placed in the planting holes 340 of the planting groove 300 through the planting basket (not shown in the figure), and water is supplied to the main pipe 440. The main pipe 440 delivers the nutrient solution to the water pipe 410, and then the nozzle 430 sprays the nutrient solution mist outward. Because the nozzle is located at the upper position of the water mist channel 530 and the water mist channel 530 is a trumpet-shaped structure that is wide at the top and narrow at the bottom, the main body of the nutrient solution mist sprayed from the nozzle 430 spreads toward the upper "wide area" to avoid a large amount of downward influx into the lower "narrow area" of the water mist channel 530, and the nutrient solution mist gradually spreads to the box body. 200 and the lower part of the planting groove 300 is filled with "sufficient nutrient solution water mist", which is beneficial to the potato seedlings to absorb the nutrient solution and thus beneficial to the growth of the potato seedlings. After a period of time, it is determined whether the position of the planting groove 300 needs to be adjusted according to the growth of the potato seedlings. The planting groove 300 is rotated so that the planting groove 300 rotates counterclockwise or clockwise. Because the water mist concentration at different positions in the water mist channel 530 is different, the position of the planting groove 300 is changed, so that the roots of the potato seedlings can contact different positions of the water mist channel 530, which is more conducive to balancing the roots of the potato seedlings in the planting groove 300. Growth, with the rotation and change of the position of the planting groove 300, the positioning pendulum 330 moves with the planting groove 300, so as to re-fix the position of the planting groove 300; after a period of time, the growth conditions of the potato seedlings in the planting grooves 300 at different positions will be different due to the different growth environments (the degree of contact with the nutrient solution mist). In this way, the positions of the planting grooves 300 at different positions are exchanged to ensure the consistent growth of the potato seedlings in the planting grooves 300 as much as possible. Specifically, the planting grooves 300 at two different positions are taken out from the slot holes 261 respectively, and then the positions of the two planting grooves 300 are exchanged.
