Description

Technical Field

[0001] This utility model relates to the technical field of soilless cultivation planting boxes, specifically a bottom drainage device for a soilless cultivation planting box. Background Technology

[0002] Soilless cultivation planting boxes are planting containers designed specifically for soilless cultivation technology. They abandon the traditional soil planting method and instead use nutrient solution or solid substrate to provide plants with the nutrients, water and oxygen needed for growth. The replacement of water in soilless cultivation planting boxes has an important impact on the planted plants, and the drainage device at the bottom of the soilless cultivation planting box is the key equipment for water replacement. Existing drainage devices for hydroponics planting boxes involve installing a water outlet pipe at the bottom of the planting box, with a filter screen at the top and an electric valve in the middle. The opening and closing of the water outlet pipe is controlled by the opening and closing of the electric valve. Water is discharged after being filtered by the filter screen. However, this type of drainage device has some problems. For example, without an intervention unit, some impurities will accumulate and adhere to the surface of the filter screen during filtration, clogging the filter pores and affecting the overall drainage effect of the device. Utility Model Content

[0003] The technical problem to be solved by this utility model is to overcome the existing defects and provide a drainage device at the bottom of a soilless cultivation planting box. As the water flows outward, it drives the impeller to rotate, thereby rotating the cleaning brush and cleaning the filter screen to prevent impurities from clogging the filter holes. This can effectively solve the problems in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a bottom drainage device for a soilless cultivation planting box, including a drainage chamber, a cleaning chamber at the upper end of the drainage chamber, a water outlet chamber at the lower end of the drainage chamber, a filter screen at the upper end of the cleaning chamber, and a cleaning mechanism.

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 1-4 This embodiment provides a technical solution: a bottom drainage device for a soilless cultivation planting box, including a drainage chamber 1, a cleaning chamber 2 at the upper end of the drainage chamber 1, a water outlet chamber 3 at the lower end of the drainage chamber 1, a filter screen 7 at the upper end of the cleaning chamber 2, and a cleaning mechanism 4. Cleaning mechanism 4 includes a rotating shaft 41, mounting plate 42, cleaning brushes 43, connecting cylinder 44, and disc brush 45. The rotating shaft 41 is rotatably connected to the inside of the drainage chamber 1 via a sealed bearing. The upper end of the rotating shaft 41 extends to the cleaning chamber 2, and the lower end of the rotating shaft 41 extends to the inside of the water outlet chamber 3. The upper end of the outer surface of the rotating shaft 41 is fixedly connected to evenly distributed mounting plates 42. The middle of each mounting plate 42 is provided with symmetrically distributed cleaning brushes 43. The middle of the mounting plate 42 and the middle of two adjacent cleaning brushes 43 are connected by evenly distributed connecting bolts. The upper end of the rotating shaft 41 is fitted with a connecting cylinder 44, which can be connected to the upper end of the rotating shaft 41 by screws. The upper end of the connecting cylinder 44 is fixedly connected to a disc brush 45. The disc brush 45 and the upper side The bristles of the four cleaning brushes 43 are all installed in conjunction with the filter screen 7. The bristles of the four cleaning brushes 43 on the lower side are all installed in conjunction with the bottom wall of the cleaning chamber 2. The rotation of the rotating shaft 41 drives the evenly distributed mounting plate 42 to rotate. The rotation of the mounting plate 42 drives the adjacent cleaning brushes 43 to rotate around the central axis of the rotating shaft 41. At the same time, the rotation of the rotating shaft 41 drives the connecting cylinder 44 to rotate. The rotation of the connecting cylinder 44 drives the disc brush 45 to rotate. During the rotation, the bristles of the disc brush 45 and the four cleaning brushes 43 on the upper side continuously contact the lower end of the filter screen 7 to prevent impurities from clogging the filter holes inside the filter screen 7. At the same time, the bristles of the four cleaning brushes 43 on the lower side clean the bottom wall of the cleaning chamber 2 during the rotation, effectively preventing the water output effect of the drainage device from being affected. The cleaning mechanism 4 also includes a spiral water outlet pipe 46 and an impeller 47. The spiral water outlet pipe 46 is symmetrically arranged between the cleaning chamber 2 and the water outlet chamber 3. The impeller 47 is fixedly connected to the lower end of the outer surface of the rotating shaft 41. The impeller 47 is located inside the water outlet chamber 3. When water flows into the water outlet chamber 3 through the two spiral water outlet pipes 46, the water flow generates a lateral thrust on the impeller 47, causing the impeller 47 to rotate clockwise. The clockwise rotation of the impeller 47 drives the rotating shaft 41 to rotate. Wherein: The upper end of the outer surface of the drainage chamber 1 is provided with an annular connecting groove 5, the inside of the annular connecting groove 5 is threadedly connected to the lower end of the mounting cylinder 6, the lower end of the mounting cylinder 6 is provided with an annular sealing groove 11, the upper end of the drainage chamber 1 is inserted into the inside of the annular sealing groove 11, the lower end of the outer arc surface of the mounting cylinder 6 is provided with an annular rib groove 9, the upper end of the inside of the annular connecting groove 5 is provided with an annular rubber pad 10, the annular rubber pad 10 and the annular rib groove 9 are installed together, the drainage chamber 1 is moved from bottom to top and the drainage chamber 1 is rotated at the same time, so that the lower end of the mounting cylinder 6 is threaded into the inside of the annular connecting groove 5. When the lower surface of the mounting cylinder 6 is tightly attached to the bottom wall of the annular connecting groove 5, the rotation of the drainage chamber 1 is stopped. At this time, the upper surface of the drainage chamber 1 is tightly attached to the top wall of the annular sealing groove 11, and the outer arc surface of the annular rubber pad 10 is tightly attached to the inner arc surface of the annular rib groove 9 to prevent water from seeping out. Wherein: the upper end of the mounting cylinder 6 is fixedly connected to the mounting flange 8. The mounting cylinder 6 is passed through the water outlet at the bottom of the soilless cultivation planting box from top to bottom. When the mounting flange 8 is in contact with the upper end face of the water outlet, the mounting flange 8 is connected to the bottom of the soilless cultivation planting box by the limit bolt. Wherein: A controller 14 is installed on the right side of the drainage chamber 1, and the input terminal of the controller 14 is electrically connected to an external power supply; Wherein: an electric valve 12 is installed at the lower end of the water outlet chamber 3, and a water outlet pipe 13 is installed at the lower end of the electric valve 12. The input end of the electric valve 12 is electrically connected to the output end of the controller 14. When the hydroponics planting box needs to discharge water, the controller 14 activates the electric valve 12, and the electric valve 12 opens. The water flows from the inside of the hydroponics planting box into the inside of the drainage chamber 1, and passes from top to bottom through the installation cylinder 6, the cleaning chamber 2, the two spiral water outlet pipes 46 and the water outlet chamber 3, and finally exits through the water outlet pipe 13.

[0016] The working principle of the bottom drainage device of the hydroponics planting box provided by this utility model is as follows: During operation, the operator first inserts the mounting cylinder 6 through the water outlet at the bottom of the hydroponics planting box from top to bottom. When the mounting flange 8 is in contact with the upper end face of the water outlet, the mounting flange 8 is connected to the bottom of the hydroponics planting box by the limiting bolt. Then, the operator moves the drainage chamber 1 from bottom to top while rotating the drainage chamber 1, so that the lower end of the mounting cylinder 6 is threaded into the interior of the annular connecting groove 5. When the lower surface of the mounting cylinder 6 is tightly in contact with the bottom wall of the annular connecting groove 5, the rotation of the drainage chamber 1 is stopped. At this time, the upper surface of the drainage chamber 1 is tightly in contact with the top wall of the annular sealing groove 11, and the outer arc surface of the annular rubber pad 10 is tightly in contact with the inner arc surface of the annular rib groove 9 to prevent water leakage. When the hydroponics planting box needs to discharge water, the controller 14 activates the electric valve 12, and the electric valve 12 opens, allowing water to flow from the interior of the hydroponics planting box into the interior of the drainage chamber 1. From top to bottom, the water flows through the installation cylinder 6, cleaning chamber 2, two spiral water outlet pipes 46, and water outlet chamber 3, finally exiting through the water outlet pipe 13. When the water flows into the water outlet chamber 3 through the two spiral water outlet pipes 46, the water flow generates a lateral thrust on the impeller 47, causing the impeller 47 to rotate clockwise. The clockwise rotation of the impeller 47 drives the rotating shaft 41 to rotate, which in turn drives the evenly distributed installation plates 42 to rotate. The rotation of the installation plates 42 drives the adjacent cleaning brushes 43 to rotate around the central axis of the rotating shaft 41. At the same time, the rotation of the rotating shaft 41 drives the connecting cylinder 44 to rotate, which in turn drives the disc brush 45 to rotate. During the rotation, the bristles of the disc brush 45 and the four cleaning brushes 43 on the upper side continuously contact the lower end of the filter screen 7, preventing impurities from clogging the filter holes inside the filter screen 7. Meanwhile, the bristles of the four cleaning brushes 43 on the lower side clean the bottom wall of the cleaning chamber 2 during the rotation, effectively preventing the water output effect of the drainage device from being affected.

[0017] It is worth noting that the controller 14 disclosed in the above embodiments controls the operation of the electric valve 12 using methods commonly used in the prior art.

[0018] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
