Technical Field

[0001] The present invention relates to the technical field of agricultural planting, in particular to a circulating agricultural planting rack for agricultural planting. Background Art

[0002] Existing agricultural planting racks primarily address the challenges of low space utilization and inconvenient management in traditional planting systems. They utilize three-dimensional, layered structures (such as multi-layered planting frames or rotating racks) to achieve dense planting. Some designs incorporate water and fertilizer recycling systems to conserve resources. Common types include fixed racks and rotating racks.

[0003] For example, Chinese patent publication number CN118355811A, the invention relates to the field of agricultural planting, in particular to an agricultural planting rack. The technical problem to be solved by the invention is to provide an agricultural planting rack with high working efficiency and good irrigation effect. An agricultural planting rack includes a first support rod, a collection frame, a support plate, a ladder, a clamping mechanism, a placement plate, a hook, a hanging ring, a first pull wire, a fixing mechanism, a fixed pulley, a second support rod, a nozzle, a water pipe, a hose, a height adjustment mechanism, a placement frame and a third support rod; the first support rod is fixed to the ground, and the side of the first support rod is fixed with a hook; the first placement plate is fixed to the top of the first support rod; the second placement plate is connected to the first placement plate through the third support rod.

[0031] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0032] See also Figures 1 to 8 The present invention provides a technical solution: a circulating agricultural planting rack for agricultural planting, comprising a bottom plate 1, side plates 2 are fixedly connected on both sides of the top surface of the bottom plate 1, and a plurality of planting frames 6 are rotatably installed between the outer walls of the two opposite sides of the two side plates 2. Each planting frame 6 is designed to be through-through, and the interior of each planting frame 6 is divided into multiple planting areas by a partition plate 23. A fixed plate 24 is fixedly connected between the inner walls of the axial upper sides of each planting frame 6. Two symmetrically distributed rotating plates 17 are rotatably installed on the bottom of each planting frame 6, and when the two rotating plates 17 are closed, their edges form an overlapped fit with the fixed plates 24 to jointly close the bottom of the corresponding planting frame 6;

[0033] It also includes a rotating assembly that can drive all planting frames 6 to rotate and ensure that the opening direction of the planting frame 6 is always upward;

[0034] It also includes a locking assembly, which causes the two rotating plates 17 to rotate when the tuber crops in all the planting areas of one of the planting frames 6 reach a preset maturity and rotate to the harvesting position, thereby opening the bottom of the planting frame 6;

[0035] The utility model further comprises a harvesting part, which collects the fallen tuber crops when the two rotating plates 17 at the bottom of one of the planting frames 6 are rotated to open the planting frame 6 .

[0036] See Figures 1 to 8 When tuber crops need to be planted, the staff will first fill the sterilized substrate into each area of ​​the planting frame 6, and then bury the germinated seed potatoes (buds facing up) and cover the top with soil. In the process of cultivating the seed potatoes, the two rotating plates 17 at the bottom of the planting frame 6 will rotate to a parallel state, and the edges of the two rotating plates 17 will overlap with the fixed plate 24 to completely seal the bottom of the planting frame 6 to prevent the soil in the planting frame 6 from falling during the cultivation process; and in the process of cultivating the seed potatoes, all the planting frames 6 are driven to rotate by the rotating assembly, so that the planting area in each planting frame 6 can receive light evenly (to avoid the top stems and leaves blocking the sunlight during static cultivation). When the tuber crops in all the planting areas in one of the planting frames 6 are When the crops have reached a preset maturity and rotated to the side, the staff will cut the stems and leaves at the top of the crops. When the crops are rotated to the bottom of the harvesting position, the locking assembly will unlock the lock of the two rotating plates 17. Under the action of gravity, the two rotating plates 17 will flip outward and open, and the mature tubers will fall into the harvesting part below with the substrate, thereby collecting the mature tubers, preventing mechanical damage caused by manual labor during the harvesting process. In addition, the mechanized collection method is more efficient than the manual collection method, and the survival rate of the tubers will be significantly improved. The entire system achieves efficient space utilization through a modular structure, which is particularly suitable for large-scale planting in limited areas. At the same time, its closed cultivation environment can effectively maintain the humidity and nutrients of the substrate, reducing the impact of the external environment on crop growth. In addition, it is worth mentioning that a watering pipe 7 is fixedly installed between the two side plates 2. The watering pipe 7 is connected to an external water pipe. When one of the planting frames 6 rotates to the highest point, water and fertilizer can be poured into the watering pipe 7 by an external drive device, and water and fertilize each planting area in the planting frame 6 through the water outlet of the watering pipe 7.

[0037] Furthermore, the locking assembly includes a cavity formed inside the fixed plate 24, with third mounting grooves 25 extending through and slidably mounted on both inner walls of the cavity of the fixed plate 24, and slots for the third mounting grooves 25 to be inserted into the outer walls of the two rotating plates 17. A second rotating shaft 29 capable of rotation is mounted on the inner wall of the fixed plate 24, and two sets of traction ropes 27 are fixedly connected to the outer wall of the second rotating shaft 29. The other ends of the two sets of traction ropes 27 are respectively fixedly connected to the two third mounting grooves 25, and first tension springs 26 are respectively mounted between the two third mounting grooves 25 and the inner walls of the cavity of the fixed plate 24.

[0038] The locking component also includes a detection component pre-embedded on the inner walls of both sides of each planting area, and the detection component can detect the maturity of the tuber crops in each planting area.

[0039] See Figure 4As can be seen from the above, in the initial stage, the two rotating plates 17 are closed, and together with the fixed plate 24, the bottom of the planting frame 6 is closed. At this time, under the force of the first tension spring 26 on the third mounting groove 25, the third mounting groove 25 will be inserted into the notch on the outer wall of the rotating plate 17, thereby fixing the fixed plate 24 and the rotating plate 17, so that the bottom maintains a stable sealing state. When the detection component detects that the crops in each planting area have reached the preset maturity, the second rotating shaft 29 is rotated by the external driving component. When the second rotating shaft 29 rotates, it drives the traction rope 27 to retract. The two third mounting grooves 25 are contracted, thereby driving the two third mounting grooves 25 to move inward, and then disengaging from the notch of the rotating plate 17 to complete the unlocking purpose. At this time, the rotating plate 17 will automatically flip downward and open under the action of gravity, so that the crops and substrates inside the planting frame 6 fall into the harvesting part below, realizing automatic collection of tubers. The overall structure is compact, does not take up additional space, and is perfectly integrated with the planting frame 6, which not only ensures sealing but also realizes automation function, greatly improves planting efficiency, reduces manual operation intensity, and provides reliable technical support for modern agricultural planting.

[0040] Furthermore, the detection component includes a groove on the inner wall of the planting frame 6, and the inner wall of the groove of the planting frame 6 is fixedly connected to a thermoplastic elastic air bag 13, and the thermoplastic elastic air bag 13 and the inner wall of the groove of the planting frame 6 together form a sealed ventilation chamber 12, and a second mounting groove 15 is provided inside the side wall of the planting frame 6, and a first piston plate 14 is slidably installed on the inner wall of the second mounting groove 15, and the first piston plate 14 separates the second mounting groove 15 into two independent cavities, and the top of the first piston plate 14 and the top of the second mounting groove 15 are connected by a spring 20, and a vent hole is provided on the inner wall of the planting frame 6 to connect the ventilation chamber 12 with the second mounting groove 15, and the first piston plate 14 is located above the vent hole, and a piston rod 16 is fixedly connected to the bottom of the first piston plate 14, and the piston rod 16 passes through the inner wall of the planting frame 6, and a socket for inserting the piston rod 16 is provided on the rotating shaft of the rotating plate 17.

[0041] See Figure 3A thermoplastic elastic airbag 13 is fixedly connected to the groove of the planting frame 6. As the tuber crops grow and expand, the thermoplastic elastic airbag 13 will gradually be squeezed, thereby increasing the air pressure in the ventilation chamber 12. When the air pressure in the ventilation chamber 12 increases, air will enter the second mounting groove 15 through the vent, thereby increasing the air pressure in the second mounting groove 15. When the tubers reach the maturity standard, the squeezing degree of the thermoplastic elastic airbag 13 reaches the limit, and the high pressure entering the second mounting groove 15 will overcome the elastic force of the spring 20, driving the first piston plate 14 to move upward, thereby disengaging the piston rod 16 from the socket of the rotating plate 17, thereby completing the unlocking of the rotating plate 17. When the crops in all the planting areas in a planting frame 6 are When all the tubers are ripe, all the piston rods 16 are disengaged from the rotating shaft of the rotating plate 17, thereby completing the preliminary unlocking of the rotating plate 17. At this time, the second rotating shaft 29 is driven to rotate by the external drive component, so that the third mounting slot 25 is disengaged from the rotating plate 17, completing the complete unlocking of the rotating plate 17. At this time, the rotating plate 17 automatically flips downward and opens under the action of gravity, and the mature tubers and substrate inside the planting frame 6 immediately fall into the harvesting part below, realizing automatic harvesting. The detection component accurately judges the maturity of the crop through mechanical pressure sensing, does not require electric drive, has high reliability and is easy to maintain. At the same time, the multi-area linkage unlocking design ensures that harvesting will only be triggered when the crops in all planting areas are ripe, effectively avoiding the problem of premature or partial harvesting, and greatly improving the harvesting quality and efficiency.

[0042] Among them, it is worth noting that the use of thermoplastic elastic airbag 13 can effectively avoid the corrosion of soil on ordinary airbags, and can significantly extend the service life of the detection component. The thermoplastic elastic airbag 13 has excellent corrosion resistance and aging resistance, and can maintain stable detection sensitivity in a humid soil environment for a long time. At the same time, the elastic modulus of the thermoplastic elastic airbag 13 can be customized according to the growth characteristics of different crops to ensure appropriate pressure changes during the tuber expansion process, providing a reliable basis for maturity judgment.

[0043] Furthermore, the rotating assembly includes a first rotating ring 3 and a second rotating ring 4 which are installed on the outer wall of the side plate 2 and can rotate. The centers of the first rotating ring 3 and the second rotating ring 4 are at different positions on the same vertical plane, and the first rotating ring 3 and the second rotating ring 4 are set congruently. A number of fixed shafts 39 are passed through and rotatably installed on the outer wall of the first rotating ring 3. A first connecting rod 5 is fixedly installed on the outer wall of each fixed shaft 39. The other end of each first connecting rod 5 is rotatably connected to the outer wall of the second rotating ring 4, and each second rotating ring 4 always remains in a vertical state.

[0044] See Figure 2 as well as Figure 8The second rotating ring 4 is driven to rotate by an external driving component, thereby driving the first rotating ring 3 to rotate through the first connecting rod 5 and the fixed shaft 39, so that the planting frame 6 can stably maintain the opening upward and rotate, so that the crops can receive light evenly, and fertilize the crops inside the planting frame 6 through the watering pipe 7 through the external driving component, and enable the staff to trim the stems and leaves more conveniently. When the crops are mature and rotate to the bottom, the two rotating plates 17 are unlocked to open the bottom of the planting frame 6 to collect the mature crops, realize fully automatic picking, and reduce manual damage to the crops.

[0045] Furthermore, the fixed shaft 39 passes through the outer wall of the first rotating ring 3 and is rotatably installed with a driven gear 34 and a second sprocket 33. The second sprocket 33 is fixedly connected to the driven gear 34. The second rotating shaft 29 passes through the outer wall of the fixed plate 24. The second rotating shaft 29 passes through the outer wall of the fixed plate 24 and is fixedly connected to the first sprocket 28. The first sprocket 28 and the second sprocket 33 are connected by a chain 35. A straight groove is provided on the outer wall of the first rotating ring 3. A rack 36 is slidably installed on the inner wall of the straight groove of the first rotating ring 3. A second tension spring is installed between the rack 36 and the inner wall of the straight groove of the first rotating ring 3. A permanent magnet is installed inside the rack 36. The outer wall of the side plate 2 is fixedly installed with an electromagnet 32.

[0046] Furthermore, each time the rack 36 pops out and engages with the driven gear 34 , it can only rotate the driven gear 34 a quarter of a turn, and when the driven gear 34 rotates half a turn, the third mounting slot 25 is disengaged from the notch of the rotating plate 17 .

[0047] See Figure 5 as well as Figure 6 When all the crops in one of the planting frames 6 are mature, all the piston rods 16 therein will be driven to move upward, thereby completing the preliminary unlocking of the rotating shaft of the rotating plate 17. At this time, the electromagnet 32 ​​is driven to work by the external driving component. When the planting frame 6 rotates to the lowest end, the electromagnet 32 ​​emits a magnetic field, thereby ejecting the rack 36 at the corresponding position, so that the rack 36 engages with the driven gear 34. As the first rotating ring 3 rotates, the rack 36 drives the driven gear 34 to rotate, thereby driving the second sprocket 33 to rotate, and then drives the first sprocket 28 to rotate through the chain 35. The first sprocket 28 drives the second rotating shaft 29 to rotate, thereby tightening the traction rope 27, so that the third mounting slot 25 is disengaged from the rotating plate 17, completing the final unlocking process of the rotating plate 17, and causing the mature crops therein to fall into the harvesting part of the rice hanging.

[0048] Among them, it is worth mentioning that each time the rack 36 pops out to mesh with the driven gear 34 and rotates the driven gear 34, it can only make the driven gear 34 rotate a quarter of a turn, so that the second rotating shaft 29 only rotates a quarter of a turn. At this time, the staff trims the stems and leaves at the top of the crops planted on this planting frame 6. When this planting frame 6 rotates to the bottom for the second time, the rack 36 pops out again to mesh with the driven gear 34, and the second rotating shaft 29 will rotate a quarter of a turn again, so that the third mounting groove 25 is completely disengaged from the rotating plate 17, causing the mature crops to fall. The quarter-turn rotation design not only ensures sufficient unlocking stroke, but also leaves sufficient operating time for stem and leaf pruning, making the entire harvesting process more efficient and orderly.

[0049] Furthermore, it also includes a harvesting part, which includes two mounting plates 30 respectively mounted vertically and slidingly on the outer walls of the two side panels 2, and an elastic telescopic rod 31 is fixedly connected between the two mounting plates 30 and the outer walls of the corresponding side panels 2, a screen 9 is fixedly connected between the two mounting plates 30, and two leak-proof plates 10 are fixedly connected to the top of the bottom plate 1, and the outer walls of the two leak-proof plates 10 are respectively fitted with the two ends of the screen 9.

[0050] See Figure 2 as well as Figure 5 The harvesting part realizes the function of buffering and shock absorption through the cooperation of the mounting plate 30 and the elastic telescopic rod 31. When the mature crops fall from the planting frame 6 onto the screen 9, the elastic telescopic rod 31 can effectively absorb the impact force to prevent the tubers from being damaged. The close fit between the leak-proof plate 10 and the screen 9 can ensure that the fallen objects can stably enter the screen 9 for screening, and the vibration screening of the screen 9 can effectively separate the tubers and the cultivation matrix. The matrix will be discharged to the bottom through the filter holes of the screen 9, leaving only the tubers above the screen 9, which is convenient for subsequent collection and processing. The entire collection process does not require manual intervention, realizes automated operation, and improves the harvesting efficiency and product quality.

[0051] In addition, it is worth mentioning that a pull-out soil holding frame 11 is provided below the screen 9 to facilitate centralized recycling of the screened cultivation substrate and realize the recycling of resources.

[0052] Furthermore, a rotatable incomplete gear 22 is installed on the outer wall of the side plate 2, and a tooth groove 37 that can engage with the incomplete gear 22 is opened on the outer wall of the second rotating ring 4. A cam 38 is coaxially fixedly installed on the incomplete gear 22, and when the cam 38 rotates, it can periodically press down the mounting plate 30.

[0053] See Figure 5 ,as well as Figure 8The incomplete gear 22 is driven by a motor fixed to the back of the side plate 2 to rotate, so that the incomplete gear 22 intermittently engages with the tooth groove 37, and then the second rotating ring 4 rotates periodically, so that there is sufficient time to water the crops in the planting frame 6, and the staff can stably trim the stems and leaves. When the incomplete gear 22 rotates, it will drive the cam 38 coaxially fixed with it to rotate. The raised part of the cam 38 can periodically press down the mounting plate 30, and the screen 9 can be vibrated through the elastic telescopic rod 31 to ensure that the substrate can be stably discharged from the filter holes of the screen 9 for subsequent classification and recovery.

[0054] Furthermore, a piston body 40 is fixedly mounted on the outer wall of the planting frame 6, a second piston plate 21 is slidably mounted on the inner wall of the piston body 40, a second connecting rod 18 is rotatably mounted on the outer wall of the rotating shaft of the rotating plate 17, a third connecting rod 19 is rotatably mounted on the other end of the second connecting rod 18, an end of the third connecting rod 19 away from the second connecting rod 18 is rotatably connected to the bottom of the second piston plate 21, and a connecting pipe that can be connected to the ventilation chamber 12 is fixedly mounted on the inner wall of the piston body 40, an air inlet connected to the outside world is opened on the top of the piston body 40, and a one-way valve is installed in the air inlet of the piston body 40 and the connecting pipe.

[0055] See Figure 3 When the rotating plate 17 is fully unlocked, the rotating plate 17 will rotate downward and open under the action of gravity. At this time, under the action of the second connecting rod 18 and the third connecting rod 19, the second piston plate 21 will move upward, and then the air in the piston body 40 will be squeezed into the ventilation chamber 12 through the connecting pipe, so that the ventilation chamber 12 will expand in the direction close to the planting frame 6, squeezing the soil therein, thereby loosening the soil structure, allowing the tubers to fall off from the planting frame 6 more smoothly, avoiding the problem of complete harvesting due to soil compaction, and utilizing the rotation of the rotating plate 17 to convert into power for loosening the soil. No additional power device is required, which simplifies the structure and improves the harvesting efficiency, ensuring that the tuber crops can be separated from the planting frame 6 completely and cleanly.

[0056] Furthermore, two limiting wheels 8 are rotatably mounted on the outer wall of the side plate 2 , and the second rotating ring 4 is jointly supported by the two limiting wheels 8 to form a rolling support structure.

[0057] The limiting wheel 8 is designed to form rolling support for the second rotating ring 4 through two limiting wheels 8, so that the rotating ring maintains a stable trajectory during rotation and effectively prevents radial deviation. This rolling support structure greatly reduces friction resistance, making rotation smoother, while reducing mechanical wear and extending the service life of the equipment. Especially when the load changes, the double-wheel support design can evenly disperse the force, ensuring the stability and reliability of the system operation, and providing a guarantee for the precise positioning of the planting frame.

[0058] The standard parts used in this embodiment can be purchased directly from the market, and the non-standard structural components recorded in the specification and drawings can also be directly processed according to existing technical common sense without any doubt.
