Description

Technical Field

[0001] This invention belongs to the field of potato cultivation technology, specifically a cultivation device for potato cultivation. Background Technology

[0002] Potatoes are one of the world's most important food crops, and the efficiency and resource utilization of seed potato cultivation directly affect the large-scale development of the industry. Currently, potato seed potato cultivation mainly adopts soil cultivation or traditional soilless cultivation methods. The water supply components of existing suspended cultivation devices are mostly at fixed angles, which cannot dynamically adjust the spray range according to the different growth stages of potato tuber enlargement and root extension. This easily leads to uneven water supply in some areas, resulting in inconsistent tuber development. In addition, the water supply of traditional hydroponics or aeroponic systems mostly relies on single spraying or simple circulation, without efficient recycling of water after impurity interception. Impurities trapped by the filter screen can easily clog the filter holes, and the retained clean water cannot be quickly returned to the storage system, resulting in water waste.

[0003] Publication No. CN112205220A discloses a potato cultivation device, including a box body with multiple partitions inside. A drain pipe is connected to the right side of the box body. The box body is equipped with a spray assembly. The assembly is connected by a horizontal pipe and a curved pipe, as well as by a gear and a rack. When the motor rotates, the circular motion of the slide rod drives the rack to slide back and forth, which in turn allows the spray head to swing back and forth, thereby improving the uniformity of the nutrient solution spray and making the potato cultivation effect better. The connection between the curved pipe and the branch pipe, as well as the setting of valves, allows cold or hot air to circulate through the curved pipe and the horizontal pipe after the water pump is turned off. This allows the temperature inside the box to be regulated by the spray of the spray head, making the temperature stability during potato cultivation better. Rotating the bolt can drive the top rod to slide inward or outward, thereby controlling the rotation of the rollers and allowing the device to be moved to any position.

[0004] The device improves the uniformity of nutrient solution spraying by rotating the horizontal and curved tubes and meshing the gears and racks, resulting in better potato cultivation. However, it cannot recycle excess water, leading to water waste. Therefore, a potato cultivation device is proposed that can dynamically adapt to the potato growth stage and simultaneously adjust the watering angle and efficiently recycle water resources.

[0018] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0019] This invention, through the coordinated arrangement of a first water supply pipe, a second water supply pipe, and a half-gear, enables the device to dynamically adjust the water spray angle to adapt to different growth stages of potatoes. The first water supply pipe provides a channel for water delivery, while several arrayed second water supply pipes expand the coverage area. A cylinder drives the first rack to slide, meshing and rotating the half-gear, thereby adjusting the spray direction of the second water supply pipe. A limiting rod slides along the limiting groove to ensure precise angle adjustment, ultimately achieving uniform water supply that is suitable for tuber enlargement and root extension.

[0020] This invention, through the combination of a second rack, a transmission gear, and a filter screen, enables the device to achieve water filtration and efficient recycling, reducing water waste. The second rack meshes with the transmission gear and moves synchronously with the first rack, driving the transmission gear to rotate. This, in turn, drives the filter screen to rise and fall along the inner wall of the water tank. The pores of the filter screen intercept impurities in the water, and the clean water flows back to the water tank. This, combined with the delivery pump and delivery pipe, forms a circulation, ultimately ensuring the smooth operation of the water replenishment system and improving water resource utilization.

[0021] This invention, through the combination of structures such as an extension plate, support rods, and positioning grooves, enables the device to quickly position and disassemble the filter screen, improving the convenience of impurity cleaning. The extension plate is fixed to the bottom of the filter screen, and two sets of symmetrical support rods provide positioning support points. The positioning sleeve slides along the positioning groove, and its sleeve hole is precisely matched with the support rod, quickly realizing the fixing and unlocking of the filter screen, facilitating timely cleaning of trapped impurities, and ultimately achieving the effect of simplifying maintenance operations and ensuring filtration efficiency.

[0031] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0032] like Figures 1 to 8 As shown, the present invention provides a potato cultivation device, including a support 1, a cultivation rack 2 fixed at the top of the support 1, a water tank 3 fixed inside the support 1, a water replenishment mechanism 6 fixed inside the support 1, a positioning mechanism 7 installed inside the support 1, a delivery pump 4 fixed outside the water tank 3, a delivery pipe 5 connected to the output end of the delivery pump 4, a connection between the input end of the delivery pump 4 and the water tank 3, and a connection between the output end of the delivery pipe 5 and a first water replenishment pipe 601.

[0033] Using the above method: By planting potato tubers in the planting trough of the cultivation rack 2, as the potato tubers swell and the root system extends, the potatoes hang downwards to grow. Activating the delivery pump 4 can pump the water inside the water tank 3 and send it through the delivery pipe 5 into the first water supply pipe 601 and the second water supply pipe 602, thereby replenishing the water for the potatoes.

[0034] like Figures 1 to 6 As shown, the water replenishment mechanism 6 includes a first water replenishment pipe 601, a second water replenishment pipe 602, and a half gear 603. The first water replenishment pipe 601 is fixed to the top of the bracket 1. The second water replenishment pipe 602 is rotatably connected inside the first water replenishment pipe 601. The half gear 603 is fixed to the outside of the second water replenishment pipe 602. The output end of the first water replenishment pipe 601 is connected to the second water replenishment pipe 602. Several groups of the second water replenishment pipes 602 are arranged in an array. The bottom end of the half gear 603 is fixed with several... The dry gear assembly includes a filter screen 613 movably connected inside the water tank 3, an extension frame 604 fixed at the top of the support 1, a limiting groove 605 formed at the top of the extension frame 604, a limiting rod 606 fixed at the top of the half gear 603, a cylinder 607 fixed at the top of the support 1, a vertical groove formed in the middle of the extension frame 604 to allow the limiting groove 605 to slide, and the inner wall of the vertical groove is in contact with the outer wall of the limiting rod 606, and two sets of cylinders 607 are provided, which are symmetrically distributed about the central axis of the support 1.

[0035] like Figures 1 to 6 As shown, a support block 608 is fixed to the drive end of the cylinder 607, a limiting sleeve 609 is fixed to the outside of the bracket 1, a first rack 610 is fixed to the outside of the support block 608, a second rack 611 is fixed to the bottom end of the first rack 610, a transmission gear 612 is rotatably connected inside the water tank 3, the outer wall of the first rack 610 fits against the inner wall of the limiting sleeve 609, the first rack 610 and the limiting sleeve 609 are slidably connected, and several sets of teeth are fixed to the top end of the first rack 610. The first rack 610 and the half gear 603 are meshed and connected. The bottom end of the second rack 611 is fixed with several sets of teeth. The outside of the transmission gear 612 is fixed with several sets of teeth. The second rack 611 and the transmission gear 612 are meshed and connected. The top end of the filter screen 613 is fixed with several sets of teeth. The filter screen 613 and the transmission gear 612 are meshed and connected. The surface of the filter screen 613 is provided with several sets of holes. The outer wall of the filter screen 613 is attached to the inner wall of the water tank 3. The filter screen 613 and the water tank 3 are slidably connected.

[0036] The above solution involves: activating cylinder 607 to push or pull back support block 608, which in turn moves first rack 610. The teeth at the top of first rack 610 then rotate half gear 603, changing the spray angle of second water supply pipe 602. Limiting groove 605 and limiting rod 606 at the top of extension frame 604 limit the rotation angle of half gear 603, preventing excessive rotation and water waste. Simultaneously, first rack 610 moves, driving second rack 611, which in turn rotates transmission gear 612. Transmission gear 612 then moves filter screen 613, allowing it to collect water blocked by impurities during filtration and fall into the water tank for recycling, thus improving water recovery efficiency.

[0037] like Figures 1 to 8 As shown, the positioning mechanism 7 includes an extension plate 701, a support rod 702, and a positioning groove 703. The extension plate 701 is fixed to the bottom end of the filter screen 613. The positioning groove 703 is provided on the outside of the water tank 3. A positioning sleeve 704 is movably connected inside the positioning groove 703. Two sets of support rods 702 are provided, and the support rods 702 are symmetrically distributed about the central axis of the extension plate 701. Two sets of positioning grooves 703 are provided, and the positioning grooves 703 are symmetrically distributed about the central axis of the water tank 3. The outer wall of the positioning sleeve 704 fits against the inner wall of the positioning groove 703. The positioning sleeve 704 and the positioning groove 703 are slidably connected. A sleeve hole is provided on the inner wall of the positioning sleeve 704, and the diameter of the sleeve hole is equal to the diameter of the support rod 702.

[0038] The above solution allows for the replacement of filter 613 after prolonged use by pulling it out. When the filter 613 is pulled out, the machine is stopped, and the positioning sleeve 704 remains in the pulled-out position. This allows for quick installation of filter 613 after aligning the support rod 702 and the positioning sleeve 704, while the teeth on the top of filter 613 remain engaged with the transmission gear 612.

[0039] The working principle and usage process of this invention are as follows: First, potato tubers are planted in the planting trough of the cultivation rack 2. As the potato tubers swell and their root systems extend, the potatoes grow downwards. Activating the delivery pump 4 draws water from the water tank 3 and directs it through the delivery pipe 5 into the first water supply pipe 601 and the second water supply pipe 602, thus replenishing the water for the potatoes. Activating the cylinder 607 pushes or pulls back the support block 608, thereby moving the first rack 610. The teeth at the top of the first rack 610 drive the half gear 603 to rotate, thereby changing the second water supply... The angle of the water pipe 602 sprays water, and the limiting groove 605 and the limiting rod 606 at the top of the extension frame 604 limit the rotation angle of the half gear 603 to avoid excessive rotation angle and waste of water resources. When the first rack 610 moves, it drives the second rack 611 to move simultaneously. Then, the second rack 611 drives the transmission gear 612 to rotate, and the transmission gear 612 drives the filter screen 613 to move. When the filter screen 613 moves, it can make the water source blocked by impurities during filtration fall into the water tank for recycling, thereby improving the efficiency of water recycling.

[0040] Finally, after long-term use, the filter 613 can be pulled out for replacement. When the filter 613 is pulled out, the machine is in a stopped state, and the positioning sleeve 704 will remain in the pulled-out position. This allows for quick installation of the filter 613 after the filter 613 is replaced by aligning the support rod 702 and the positioning sleeve 704. At this time, the teeth on the top of the filter 613 are still in a meshing state with the transmission gear 612.

[0041] The planting troughs of the cultivation rack 2 are arranged in an array, with drainage holes reserved in the troughs. Excess water flows back to the water tank 3 through the drainage holes, forming a preliminary water circulation. The delivery pump 4 is fixed to the outer wall of the water tank 3, and its input end extends to the bottom of the water tank 3 to ensure that clean water is drawn from the bottom. The delivery pipe 5 is sealed to the first water supply pipe 601 to avoid leakage during water delivery and ensure water supply efficiency.

[0042] The first water supply pipe 601 is horizontally fixed to the top of the bracket 1. Several sets of second water supply pipes 602 are vertically connected to the bottom of the first water supply pipe 601, evenly distributed in an array to expand the water supply coverage. The bottom end of the second water supply pipe 602 has a spray hole, through which water is sprayed out in a mist, increasing the contact area with the potato roots. The half gear 603 is fixed to the middle of the second water supply pipe 602, and its teeth precisely mesh with the teeth of the first rack 610 to ensure smooth power transmission. Extension frame 6 04 Symmetrically fixed on both sides of the top of the bracket 1, the limiting groove 605 has an arc-shaped structure, the bottom end of the limiting rod 606 is fixed to the half gear 603, and the top end is embedded in the limiting groove 605 to limit the rotation angle of the half gear 603 and prevent the second water supply pipe 602 from deflecting excessively and causing water supply deviation. The cylinder 607 is fixed to the top of the bracket 1 by bolts. The two sets of cylinders 607 act synchronously to drive the support block 608 to move in the horizontal direction, thereby driving the first rack 610 to slide in the limiting sleeve 609.

[0043] The inner wall of the limiting sleeve 609 fits against the outer wall of the first rack 610, restricting the first rack 610 to move only in the horizontal direction, thus avoiding deviation that could affect the meshing accuracy. The first rack 610 and the second rack 611 are integrally formed. When moving synchronously, the second rack 611 meshes with the transmission gear 612, driving the transmission gear 612 to rotate around its own axis. The transmission gear 612 is rotatably connected to the bearing seat inside the water tank 3, and its other side meshes with the teeth at the top of the filter screen 613, converting the rotational motion into the back-and-forth reciprocating motion of the filter screen 613. The outer wall of the filter screen 613 fits tightly against the inner wall of the water tank 3, and there is no gap or shaking during sliding. The holes on its surface have uniform diameters and are used to intercept impurities, root debris, and other pollutants in the return water. When the filter screen 613 moves, the water at the top moves with the filter screen 613, breaking through the barrier layer formed by the accumulation of impurities and quickly flowing back to the bottom of the water tank 3, thus avoiding water stagnation and waste.

[0044] The extension plate 701 of the positioning mechanism 7 is welded to the bottom end of the filter screen 613. Two sets of support rods 702 are vertically fixed to both ends of the extension plate 701, corresponding one-to-one with the positions of the positioning grooves 703. The positioning grooves 703 are opened on the outer wall of the water tank 3. The inner wall of the positioning sleeve 704 fits against the inner wall of the positioning groove 703 and can slide along the positioning groove 703. Its sleeve hole is adapted to the diameter of the support rod 702 to achieve precise positioning. When replacing the filter screen 613, the extension plate is pulled outward after the machine is stopped. Plate 701 and filter screen 613 slide outward along the inner wall of water tank 3. Support rod 702 drives positioning sleeve 704 to move synchronously along positioning groove 703 until filter screen 613 is completely detached from water tank 3. After removing the old filter screen 613, align the support rod 702 of the new filter screen 613 with the sleeve hole of positioning sleeve 704 and push extension plate 701 inward. Filter screen 613 is inserted along the hole of positioning groove 703 until the teeth at the top of filter screen 613 are fully engaged with transmission gear 612, completing the installation.
