Detailed Implementation
[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0015] Please see Figure 1-3 This embodiment provides a technical solution: a hydroponic vegetable cultivation rack, including a support frame 1, which provides support for the setting of hydroponic vegetable cultivation components. The front end of the support frame 1 is provided with a water trough frame 2, which is respectively set on the stepped platform surface at the front end of the support frame 1 to provide space for the placement of hydroponic liquid. The support plate surface at the upper end of the inner arc surface of the water trough frame 2 is provided with a cultivation tray 3 to provide space for the cultivation of hydroponic vegetables. It also includes a water changing mechanism 4. Water changing mechanism 4: It includes a drainage trough 41, a baffle 42, and a liquid level control hole 43. The drainage trough 41 is respectively set at the front end of the inner right side of the water tank frame 2. The drainage trough 41 is connected to the interior of the adjacent water tank frame 2 below. The interior of each drainage trough 41 is vertically slidably connected to a baffle 42. The baffle 42 is an L-shaped plate. The upper end of the vertical plate of each baffle 42 is provided with a liquid level control hole 43. By changing the vertical position of the baffle 42, the liquid level height in the water tank frame 2 is limited by the liquid level control hole 43. Excess hydroponic solution will be discharged into the interior of the adjacent water tank frame 2 below through the drainage trough 41, which facilitates continuous drainage and continuous water intake for all water tank frames 2, making the hydroponic solution more convenient. The water changing mechanism 4 also includes a rubber pad 44, which is respectively set on the vertical plate of the baffle 42. The left side of the plate seals the left side of the baffle 42 and the inner left side of the drainage trough 41. The water changing mechanism 4 also includes guide posts 45, insertion holes 46, insertion posts 47, and locking bolts 48. The guide posts 45 are respectively set on the upper surface of the horizontal plate of the baffle 42. The guide posts 45 pass through the through holes in the top wall of the drainage trough 41. The outer arc surface of the guide posts 45 is provided with vertically evenly spaced insertion holes 46. The locking bolts 48 are threaded into the screw holes of the support plate on the upper surface of the water tank frame 2. The front end of each locking bolt 48 is provided with an insertion post 47. The insertion post 47 is inserted into the insertion hole 46 corresponding to the longitudinal position. Rotating the locking bolt 48, through the threaded connection between the locking bolt 48 and the support plate on the upper surface of the water tank frame 2, causes the locking bolt 48 to drive the insertion post 47 to move back and forth. When the insertion post 47 moves forward... When the insert post 47 is inserted into the socket 46, the vertical position of the baffle 42 is restricted. When the insert post 47 moves backward and disengages from the socket 46, the restriction on the baffle 42 is lifted, and the vertical position of the baffle 42 can be adjusted. The upper end of each guide post 45 is provided with a connecting plate 5, and the lower surface of each connecting plate 5 is provided with a sliding post 6. The lower end of each sliding post 6 passes through the guide hole on the upper surface of the water tank frame 2. A return spring 7 is provided between the lower surface of the connecting plate 5 and the upper surface of the adjacent water tank frame 2. The return spring 7 is movably sleeved on the outer arc surface of the sliding post 6. The vertical sliding of the sliding post 6 with the guide hole provides guide support for the extension and retraction of the return spring 7. The return spring 7 provides elastic limit for the baffle 42, making it easy for the baffle 42 to return to the maximum upward position. The inner wall of the right side of the drainage trough 41 All are equipped with mounting holes, and each mounting hole is equipped with a scale plate 8. The scale plate 8 is a transparent plate. The adjustment position of the baffle 42 is determined according to the horizontal value of the bottom wall of the liquid level control hole 43 on the scale plate 8. A water receiving frame 11 is placed at the front end of the support frame 1. The water receiving frame 11 is installed in conjunction with the water outlet of the bottommost water tank frame 2 to collect the discharged liquid. Water inlet pipes 9 are provided at the water inlet on the right side of the water receiving frame 11 and the water inlet on the right side of the water tank frame 2. A connecting pipe 10 is provided on the lower surface of the water tank frame 2. The upper end of the connecting pipe 10 is connected to the adjacent drainage tank 41, and the lower end of the connecting pipe 10 is inserted into the adjacent water inlet pipe 9, so as to connect the two vertically adjacent water tank frames 2 and the bottommost water tank frame 2 and the water receiving frame 11.
[0016] The working principle of the hydroponic vegetable cultivation rack provided by this utility model is as follows: During the hydroponic vegetable cultivation process, the hydroponic vegetables are placed in the cultivation trough within the cultivation tray 3 for cultivation. The roots of the hydroponic vegetables are immersed in the hydroponic solution within the water tank frame 2. At this time, the baffle 42 is in its maximum upward position, and the insertion post 47 is inserted into the insertion hole 46 corresponding to the longitudinal position, thus restricting the vertical position of the baffle 42. The bottom wall of the liquid level control hole 43 is higher than the liquid surface of the hydroponic solution, and the liquid level fluctuation will not cause the hydroponic solution to flow out of the liquid level control hole 43. When it is necessary to replace the hydroponic solution, the lock is rotated. Bolt 48, through locking bolt 48, is threadedly connected to the support plate on the upper surface of the water tank frame 2, causing locking bolt 48 to drive the insertion post 47 to move backward, so that the insertion post 47 leaves the insertion hole 46. Then, overcoming the elastic force of the return spring 7, it presses the sliding column 6 downward, so that the insertion hole 46 on the uppermost side of the sliding column 6 corresponds to the longitudinal position of the insertion post 47. Then, the locking bolt 48 is reversed, so that the insertion post 47 is inserted into the uppermost insertion hole 46. At this time, the baffle 42 is in the maximum downward position, and the hydroponic solution in the water tank frame 2 enters the drainage tank 41 through the liquid level control hole 43. With the connection of 10, the hydroponic solution flows sequentially through the water tank frames 2 distributed from top to bottom and finally enters the water receiving frame 11, directly discharging all the hydroponic solution into the water receiving frame 11. After the drainage is completed, the insert 47 is pulled out of the insertion hole 46 again. According to the required hydroponic solution level inside the water tank frame 2, the vertical position of the baffle 42 is adjusted. The adjustment position of the baffle 42 is determined according to the horizontal value corresponding to the bottom wall of the liquid level control hole 43 on the scale plate 8. Then, the position of the adjusted baffle 42 is restricted by inserting the insert 47 into the insertion hole 46. After adjusting the positions of the baffles 42 inside the water tank frame 2, simply continue pouring the hydroponic solution into the uppermost water tank frame 2. When the liquid level in the water tank frame 2 is level with the bottom wall of the liquid level control hole 43, as the hydroponic solution is poured in again, the excess hydroponic solution will enter the drainage tank 41 and enter the adjacent water tank frame 2 below through the connection between the water inlet pipe 9 and the connecting tube 10. When the bottommost water tank frame 2 starts to discharge liquid, stop pouring the hydroponic solution. Quickly pour the hydroponic solution into all water tank frames 2 to the specified liquid level. Finally, reset the baffles 42 to complete the replacement of the hydroponic solution.
