Description

Technical Field

[0001] The invention relates to the technical field of soilless cultivation, in particular to a cultivation rack for soilless cultivation of ginger. Background Art

[0002] The cultivation racks used for soilless cultivation of ginger usually include components such as a stable frame, culture dishes or planting troughs, irrigation systems, nutrient solution circulation systems, light regulation devices, and environmental control systems. They can support and manage the growth of ginger plants in a soilless environment during their growth cycle, ensuring that ginger can obtain sufficient water, nutrients, and suitable growth conditions even without soil.

[0003] In the process of soilless cultivation of ginger, continuous drip irrigation is a common irrigation method. However, due to the tiny drip holes, the drip irrigation speed is usually slow. In order to maintain a continuous water supply, the water injector must be turned on for a long time, which not only consumes a lot of energy, but also shortens the service life of the water injector. At the same time, the traditional stepped cultivation rack makes the cultivated ginger stay in a fixed position for a long time. Some plants cannot get enough light for a long time, and changing the position of each plant is usually troublesome, which not only limits the photosynthesis efficiency of ginger, but also affects the overall growth quality and yield.

[0004] Based on the above situation, the present invention provides a cultivation rack for soilless cultivation of ginger. Summary of the invention

[0007] In a preferred embodiment of the present invention, a drainage groove is opened at the lower part of the support frame close to the press frame. The drainage groove is located on the outside of the press frame and is used to drain water that seeps out of the press frame from the water storage cavity of the support frame.

[0008] In a preferred embodiment of the present invention, it also includes a magnetic baffle corresponding to the spray pipe, the magnetic baffle is slidably connected to the corresponding spray pipe, the magnetic baffle is provided with an opening corresponding to each of the spray holes, when the spray holes are aligned with the corresponding openings, water in the spray pipe flows out, a magnetic ring is fixedly connected to the side of the spray pipe away from the pressure frame, a magnetic pull frame is rotatably connected between all the magnetic baffles, a plurality of magnetic rods are fixed to the pressure frame, and the magnetic rods are slidably connected to the adjacent support frames.

[0009] In a preferred embodiment of the present invention, the magnetic retaining frame moves toward a side close to the adjacent magnetic ring until they are in contact with each other for magnetic attraction. At this time, the spray hole is aligned with the corresponding opening, and the magnetic rod is magnetically engaged with the magnetic pull frame.

[0010] In a preferred embodiment of the present invention, at least four card racks are further included, wherein the card racks are slidably connected to the support racks on that side, tension springs are fixedly connected between the card racks and the support racks on that side, and at least four clamping blocks are fixedly connected to the rotating rack close to one side of the card racks, wherein the clamping blocks squeeze the card racks when the clamping blocks rotate, and the card racks clamp the clamping blocks when the clamping blocks stop rotating.

[0011] In a preferred embodiment of the present invention, it also includes at least two clamping rods, which are slidably connected to the support frame close to the pressure frame, and the pressure frame is fixed with a guide rod corresponding to the clamping rod, and a second spring is fixed between the clamping rod and the adjacent support frame, and the support frame close to the pressure frame is adjacent to the one-way valve and is inserted with an injection tube.

[0012] In a preferred embodiment of the present invention, the guide rod is squeezed and matched with the corresponding clamping rod, the injection tube is provided with a clamping groove corresponding to the clamping rod, and the clamping rod and the clamping groove corresponding to the injection tube are mutually clamped.

[0013] In a preferred embodiment of the present invention, a push-pull ring is further included, and the push-pull ring is slidably connected to the support frame on one side, and the push-pull ring is fixed with a stopper corresponding to the cultivation box for limiting the position of each cultivation box.

[0014] Compared with the prior art, the present invention has the following advantages: the present invention intermittently outputs water to the water storage chamber of the support frame through a water injection machine, and then turns off the water injection machine. During this period, the pressure frame is used to automatically and slowly press the water in the water storage chamber of the support frame into the sprinkler pipe for long-term drip irrigation, thereby significantly reducing the operating time of the water injection machine, so that the water injection machine only needs to work in a specific time period, which can significantly reduce its operating time, save electricity and other energy consumption, and also help to extend the service life of the equipment and reduce maintenance costs.

[0015] The present invention uses the water storage cavity of the support frame as a buffer zone, and can continue to provide a stable water supply when the water source supply is unstable or the water injection machine stops working, thereby ensuring the continuity of the drip irrigation system.

[0016] The present invention can timely switch the position of the ginger seedlings by rotating the rotating frame along the supporting frame by 90 degrees, and the spray pipe drives the cultivation box to rotate by 90 degrees at a fixed time, so as to ensure that the ginger seedlings in each cultivation box obtain balanced light, and the operation is simple and convenient.

[0017] The present invention blocks the spray holes of the spray pipe when water is stored and opens the spray holes of the spray pipe when water injection is stopped, thereby ensuring that there is almost no drip irrigation in the early stage of full storage, and in the later stage, the same water is uniformly pressed into each spray pipe through the pressure frame to achieve the effect of uniform water spraying, thereby preventing more water from flowing downward into the lower spray pipe in the early stage of full storage, resulting in serious imbalance of drip irrigation water in the high-position cultivation box and the low-position cultivation box.

[0018] The present invention can fix the rotating frame when the rotation stops through the cooperation of the clamping frame and the clamping block, so as to prevent the rotating frame from rotating randomly during photosynthesis, thereby causing the spray pipe and the cultivation box to rotate randomly.

[0019] The present invention cooperates with the clamping rod and the clamping grooves of the injection tube. When injecting water, there is no need to continuously press the injection tube by hand, and the injection tube can be ensured not to be detached from the support frame during the water injection period. When the water storage cavity of the support frame is full of water, the injection tube can be automatically detached from the tube.

[0020] The present invention limits each cultivation box by means of a stopper, so that each cultivation box will not be unbalanced and deflected forward or backward due to different weights of ginger seedlings cultivated in front and behind, thereby preventing the cultivation box from tipping over and leaking.

DETAILED DESCRIPTION

[0034] First of all, it should be pointed out that in the different described embodiments, the same parts are provided with the same reference numerals or the same component names, wherein the disclosure contained in the entire description can be transferred to the same parts with the same reference numerals or the same component names. Selected positional descriptions in the description, such as top, bottom, lateral, etc., also refer to the directly described and shown figures and are transferred to the new positions in the case of a change in position.

[0035] Embodiment 1: A cultivation frame for soilless cultivation of ginger, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 6As shown, it includes a base 1, support frames 2 are fixedly connected to both sides of the left side of the base 1, a water storage cavity is arranged on the upper part of the support frame 2 on the right side, a one-way valve 201 is arranged in the support frame 2 on the right side, which is used to limit the unidirectional flow of water into the water storage cavity of the support frame 2, a rotating frame 3 is connected in the support frame 2, four circumferentially distributed spray pipes 4 are rotatably connected between the two rotating frames 3, and the bottoms of the spray pipes 4 are provided with spray holes 10 distributed at equal intervals, and a cultivation box 5 is fixed on the spray pipe 4, a pressing frame 6 is slidably connected in the water storage cavity of the support frame 2 along the left and right directions, a drainage groove 601 is opened at the lower part of the support frame 2 on the right side, and the drainage groove 601 is located at the lower right side of the pressing frame 6, which is used to discharge the water that seeps out of the pressing frame 6 in the water storage cavity of the support frame 2, the rotating frame 3 on the right side is opened with four circumferentially distributed through holes, and the rotating frame 3 on the right side is connected with each spray pipe 4 through the through holes, and four first springs 7 are fixed between the pressing frame 6 and the adjacent support frames 2.

[0036] The ginger seedlings are placed in each cultivation box 5, and the output pipe of the water injection machine is inserted into the water storage cavity of the support frame 2, and water is injected into the one-way valve 201 through the output pipe of the water injection machine at high pressure. The water flows into between the pressing frame 6 and the rotating frame 3 through the one-way valve 201, and then flows into the corresponding spray pipe 4 through the through holes of the right rotating frame 3, and finally flows into the corresponding cultivation box 5 through the spray holes 10 of the spray pipe 4, so as to achieve the effect of drip irrigation for the ginger seedlings in each cultivation box 5. Since the spray holes 10 of the spray pipe 4 have a small diameter, the water outflow speed of the spray pipe 4 is much smaller than the water inflow speed. The first spring 7 is then stretched, so that the water storage chamber of the support frame 2 is filled with water. Subsequently, the water injector is turned off to suspend water injection. As water slowly drips out through the spray hole 10 of the spray pipe 4, the water in the spray pipe 4 gradually decreases, and the first spring 7 is adaptively reset, so that the press frame 6 adaptively slides to the left until all the water in the water storage chamber of the support frame 2 is discharged, and high-pressure water is injected into the one-way valve 201 through the output pipe of the water injector again.

[0037] This is repeated. In summary, the present invention intermittently outputs water to the water storage chamber of the support frame 2 through the water injection machine, and then turns off the water injection machine. During this period, the pressure frame 6 is used to automatically and slowly press the water in the water storage chamber of the support frame 2 into the sprinkler pipe 4 for long-term drip irrigation, thereby significantly reducing the operating time of the water injection machine, so that the water injection machine only needs to work in a specific time period, which can significantly reduce its operating time, save electricity and other energy consumption, and also help to extend the service life of the equipment and reduce maintenance costs.

[0038] At the same time, the present invention uses the water storage chamber of the support frame 2 as a buffer zone, so as to continue to provide a stable water supply when the water supply is unstable or the water injection machine stops working, thereby ensuring the continuity of the drip irrigation system.

[0039] In addition, during the cultivation process, the rotating frame 3 can be regularly rotated ninety degrees along the supporting frame 2, the rotating frame 3 drives the spray pipe 4 to rotate ninety degrees regularly, and the spray pipe 4 drives the cultivation box 5 to rotate ninety degrees regularly. The ginger seedlings can be changed in position regularly through simple operations, thereby ensuring that the ginger seedlings in each cultivation box 5 obtain balanced light, and during the rotation process, the rotating frame 3 is rotatably connected to the spray pipe 4, allowing the cultivation box 5 to rotate freely according to the balance of gravity and automatically adjust to the lowest potential energy state, that is, parallel to the ground. In this way, the cultivation box 5 can automatically swing to a state parallel to the ground when rotated to any position.

[0040] Embodiment 2: Based on embodiment 1, Figure 5-Figure 7 As shown, it also includes a magnetic retaining frame 8 corresponding to the spray pipe 4, the magnetic retaining frame 8 is slidably connected to the corresponding spray pipe 4, and the magnetic retaining frame 8 is provided with openings corresponding to the spray holes 10. When the spray holes 10 are aligned with the corresponding openings, the water in the spray pipe 4 flows out into the cultivation boxes 5. A magnetic ring 9 is fixedly connected to the left side of the spray pipe 4, and the magnetic retaining frame 8 moves to the side close to the adjacent magnetic ring 9 until they are in contact with each other and magnetically attracted. At this time, the spray holes 10 are aligned with the corresponding openings, and a magnetic pull frame 11 is rotatably connected between all the magnetic retaining frames 8. Four magnetic rods 12 are fixedly connected to the left side of the pressing frame 6, and the magnetic rods 12 are slidably connected to the adjacent support frame 2, and the magnetic rods 12 and the magnetic pull frame 11 are magnetically attracted.

[0041] When the pressing frame 6 slides to the right, the pressing frame 6 drives the magnetic rod 12 to move to the right, and the magnetic rod 12 pulls the magnetic pulling frame 11 to the right through magnetic force, thereby pulling the magnetic blocking frame 8 to move to the right relative to the adjacent spray pipe 4, so that the spray holes 10 of the spray pipe 4 are misaligned with the openings of the magnetic blocking frame 8. In this way, during the water storage process in the water storage chamber, the spray holes 10 of the spray pipe 4 are blocked by the magnetic blocking frame 8.

[0042] When the water storage chamber of the support frame 2 is full of water, continuing to inject water will cause the water pressure to act on the left side of the magnetic baffle frame 8, causing the magnetic baffle frame 8 to move to the left, thereby aligning the spray holes 10 of the spray pipe 4 with the openings of the magnetic baffle frame 8, and the magnetic baffle frame 8 drives the magnetic pull frame 11 to move to the left and disengage from the magnetic rod 12, and the magnetic baffle frame 8 moves to the left until it is magnetically attracted to the magnetic ring 9, and the magnetic baffle frame 8 is adsorbed by the magnetic ring 9, thereby pulling the magnetic pull frame 11 to prevent the magnetic pull frame 11 from being sucked back by the magnetic rod 12 when the pressure frame 6 is completely reset due to the slow reset of the magnetic rod 12 following the pressure frame 6, thereby causing the spray holes 10 to be blocked. In this way, when the water injection is stopped after the water is filled and during the subsequent drip irrigation process, the magnetic baffle frame 8 no longer blocks the spray holes 10, so that the spray holes 10 of the spray pipe 4 continue to remain in an open state.

[0043] In summary, the present invention blocks the spray holes 10 of the spray pipe 4 when storing water, and opens the spray holes 10 of the spray pipe 4 when stopping water injection, thereby ensuring that there is almost no drip irrigation in the early stage of full storage, and in the later stage, the same water is uniformly pressed into each spray pipe 4 through the pressure frame 6 to achieve the effect of uniform water spraying, thereby avoiding that the water in the early stage of full storage flows more downward into the lower spray pipe 4, resulting in a serious imbalance of water in the high-position cultivation box 5 and the low-position cultivation box 5 for drip irrigation.

[0044] Embodiment 3: Based on embodiment 2, Figure 8 and Fig. 9 As shown, six card frames 13 are also included. The card frames 13 are slidably connected to the support frame 2 on the left. A tension spring 14 is fixedly connected between the card frames 13 and the support frame 2 on the left. Four clamping blocks 15 are fixedly connected to the rotating frame 3 on the left. When the clamping blocks 15 rotate, the clamping blocks 15 squeeze the card frames 13 to slide to the left. When the clamping blocks 15 stop rotating, the card frames 13 slide to the right and clamp the clamping blocks 15.

[0045] When the rotating frame 3 is rotated, the rotating frame 3 drives the card block 15 to rotate, the card block 15 squeezes the card frame 13, and the tension spring 14 is stretched. When the card block 15 is separated from the card frame 13, the tension spring 14 is reset to drive the card frame 13 to reset. When the rotating frame 3 drives the card block 15 to rotate until it contacts with the card frame 13 again, the card block 15 squeezes the card frame 13, and the tension spring 14 is stretched. When the card block 15 rotates ninety degrees, the card frame 13 is separated from the card frame 13, the tension spring 14 is reset to drive the card frame 13 to reset and clamp the card block 15, thereby fixing the rotating frame 3 to prevent the rotating frame 3 from rotating at will during photosynthesis, thereby causing the spray pipe 4 and the cultivation box 5 to rotate at will. If it is necessary to control two cultivation boxes 5 to be on the top and two cultivation boxes 5 to be on the bottom, the rotating frame 3 is controlled to drive the card block 15 to rotate to the card frame 13 stuck at the front upper and rear upper parts.

[0046] Embodiment 4: Based on embodiment 3, Fig.10 and Fig.11 As shown, it also includes four clamping rods 16, which are slidably connected to the support frame 2 on the right side, and the pressure frame 6 is fixedly connected with a guide rod 17 corresponding to the clamping rod 16, and the guide rod 17 is squeezed and matched with the corresponding clamping rod 16, and a second spring 171 is fixedly connected between the clamping rod 16 and the adjacent support frame 2, and a filling tube 18 is inserted on the side of the support frame 2 on the right side adjacent to the one-way valve 201, and the filling tube 18 has a slot corresponding to the clamping rod 16, and the slots corresponding to the clamping rod 16 and the filling tube 18 are engaged with each other.

[0047] Before water injection, insert the injection tube 18 (the output tube of the water injection machine) into the water storage chamber of the support frame 2. The injection tube 18 first squeezes the clamping rod 16, and the second spring 171 is stretched. When the respective clamping slots of the injection tube 18 correspond to the clamping rod 16, the second spring 171 resets and drives the clamping rod 16 to reset to the clamping slot corresponding to the injection tube 18. In this way, when water is injected, there is no need to continuously press the injection tube 18 by hand, and it can also ensure that the injection tube 18 will not be separated from the support frame 2 during the water injection period. When the pressing frame 6 moves to the right, it drives the guide rod 17 to move to the right. The guide rod 17 squeezes the clamping rod 16 through the wedge surface to slide toward the side of the stretched second spring 171, so that the clamping rod 16 no longer clamps the injection tube 18, so that when the water storage chamber of the support frame 2 is full of water, the injection tube 18 can be automatically detached from the tube.

[0048] like Fig.12 As shown, it also includes a push-pull ring 19, which is slidably connected to the support frame 2 on the left side. The push-pull ring 19 is fixed with a stopper 20 corresponding to the cultivation box 5. Pushing the push-pull ring 19 to the right causes the stopper 20 to move to the right to limit each cultivation box 5.

[0049] After the rotating frame 3 is rotated ninety degrees along the supporting frame 2 to a locked position, the push-pull ring 19 is pushed to the right, and the push-pull ring 19 drives the stopper 20 to move to the right, so that the upper stopper 20 is limited to the bottom of the top cultivation box 5, the lower stopper 20 is limited to the top of the bottom cultivation box 5, the front stopper 20 is limited to the rear of the front cultivation box 5, and the rear stopper 20 is limited to the front of the rear cultivation box 5. In this way, each cultivation box 5 will not be unbalanced and deflected forward or backward due to the different weights of the ginger seedlings cultivated in the front and back, thereby avoiding the situation where the cultivation box 5 overturns and leaks.

[0050] Although the present disclosure has been described with respect to only a limited number of embodiments, those skilled in the art having benefit of this disclosure will appreciate that various other embodiments can be devised without departing from the scope of the present invention. Accordingly, the scope of the present invention should be limited only by the appended claims.
