Description

Technical Field

[0001] The invention relates to the field of crop cultivation devices, and in particular to a planting and cultivation device for cultivating crops. Background Art

[0002] Modern crop cultivation is indeed not limited to traditional soil cultivation. A variety of new models have emerged, among which soilless cultivation technology and three-dimensional agricultural models (such as column cultivation, wall cultivation, rotary cultivation, etc.) are particularly prominent. These models have increased the yield and efficiency per unit area by making full use of space, and have also promoted the development of agricultural modernization.

[0003] For example, a patent with a patent authorization publication number of CN221240997U and an announcement date of 2024-07-02 discloses a rotating device for agricultural planting, including a support member, the support member including a support, a support frame and a side plate, wherein a fixing nail is vertically installed at the bottom end of the support, and the fixing nail on the support is used to vertically fix the support, the support frame is vertically fixed on the top surface of the support, and the upper and lower ends of the support frame are horizontally fixed with guide rods, a first fixed plate is vertically arranged on the support frame, and the rotating rod on the first fixed plate is rotatably connected to the middle part of the support frame, the side plate is vertically arranged on one side of the support frame, and the upper and lower ends of the side plate are fixed with a orifice plate, and the orifice plate is slidably connected to the guide rod on the support frame, a second fixed plate is vertically arranged in the middle of the side plate, and the second fixed plate is rotatably connected to the side plate. Since using seedling pots for seedling cultivation is a common method in crop cultivation, placing seedling pots in planting boxes can be regarded as a more intensive and systematic cultivation method. Planting boxes can accommodate multiple seedling pots, thereby improving space utilization and allowing more crops to be planted per unit area. However, the above scheme still has certain shortcomings in actual use. For example, during use, there is a lack of a design for automatically taking and placing multiple seedling pots from the planting box, which means that during the crop cultivation process, the operator needs to manually take and place the seedling pots. This process is relatively cumbersome and increases the labor intensity of the operator. In addition, the manual method of taking and placing seedling pots will significantly reduce the overall work efficiency in the case of large-scale planting or frequent feeding and unloading, affecting the cultivation progress and yield of crops.

[0004] Based on the above situation, the present invention proposes a planting and cultivating device for cultivating crops that is easy to take and place. Summary of the invention

[0037] like Figure 2 and Figure 3 As shown, the limiting assembly includes a threaded sleeve 114, and the threaded sleeves 114 symmetrically distributed along the arch frame 101 are all fixedly connected to the support base 1, and the four threaded sleeves 114 are all threadedly connected to the adjusting screw rods 11, and the pressure rods 12 are rotatably connected between the two adjusting screw rods 11 along the horizontal direction, and the left and right sides of the shed cloth 1101 are symmetrically fixed with connecting ropes 15 on the front and back, and the movable ends of the four connecting ropes 15 are fixedly connected with hooks 14, and the four hooks 14 are snap-fitted with the support base 1.

[0038] like Figure 3 and Figure 4 As shown, the opening and closing assembly includes a sliding frame 191, which is slidably connected to the right side of the rotating rod 112. The left side of the sliding frame 191 is rotatably connected to four auxiliary connecting frames 111 evenly distributed along the circumference, and the adjacent main connecting frames 110 and auxiliary connecting frames 111 are all slidably connected.

[0039] like Figure 5 As shown, the first transmission assembly includes a pulley 117 . The two pulleys 117 are respectively fixed to the left portion of the rotating shaft 1151 , and a belt 118 is wound around the two pulleys 117 .

[0040] like Figure 8-Figure 11 As shown, it also includes a stabilizing mechanism for locking the sliding frame 191 when taking and placing the seedling pot 113. The stabilizing mechanism is arranged on the carrier 120, and the stabilizing mechanism includes a guide wheel 21, which is fixed to the right side of the carrier 120. The right front side of the support base 1 is fixedly connected to a guide member 2, and the right side of the connecting block 123 is fixedly connected to an extrusion member 22. A moving member 25 is slidably connected to the right support member 17, and a return spring 2 is connected between the right side of the moving member 25 and the right support member 17. 6. The sliding frame 191 is rotatably connected to the moving member 25. The front side of the moving member 25 is fixedly connected to a fixing member 23. The right side of the supporting base 1 is fixedly connected to a limiting member 24. The four auxiliary connecting frames 111 are fixedly connected to limiting blocks 27. The extrusion member 22 is extruded and matched with the fixing member 23. The guide wheel 21 is snap-fitted with the four limiting blocks 27. The guide wheel 21 is also snap-fitted with the guide member 2. The sliding frame 191 is provided with four sockets evenly distributed along the circumferential direction. The limiting member 24 is snap-fitted with the sliding frame 191.

[0041] When it is necessary to build a greenhouse, first cover the three arch frames 101 with the greenhouse cloth 1101, then extend the front and rear sides of the greenhouse cloth 1101 from under the pressure rod 12, and then turn the adjusting screw rod 11 forward, which will drive the pressure rod 12 to move downward to press the greenhouse cloth 1101, and finally hook the four hooks 14 on the supporting base 1. At this time, the greenhouse cloth 1101 has been built, and the staff can enter and exit the greenhouse through the door. When it is necessary to place the seedling pots 113 on the main connecting frame 110, the staff first takes four placement racks 122 to the seedling room, and each placement rack 122 is placed with at least five seedling pots 113 containing seedlings, and then the placement rack 122 with the seedling pots 113 is placed on the connecting base 13, so that the U-shaped channel of the placement rack 122 is aligned with the U-shaped channel of the connecting base 13 up and down.

[0042] Then, the driving motor 121 is controlled to drive the lower rotating shaft 1151 to rotate clockwise, thereby driving the upper rotating shaft 1151 and the sprocket 116 to rotate clockwise through the pulley 117 and the belt 118, and then the chain 119 drives the connecting block 123 and the supporting frame 120 to rotate clockwise. When the clockwise rotating supporting frame 120 rotates to the bottom of the connecting base 13, the supporting frame 120 will be aligned with the placing frame 122 and the U-shaped channel of the connecting base 13. As the supporting frame 120 continues to rotate clockwise, The supporting frame 120 will clamp the seedling basin 113 on the placing frame 122, and the connecting block 123 will drive the supporting frame 120, the seedling basin 113, the guide wheel 21, and the extrusion piece 22 to rotate clockwise together. When the clockwise rotating extrusion piece 22 contacts the fixing piece 23, the extrusion piece 22 will squeeze the fixing piece 23 to drive the moving piece 25 to move to the right, and the return spring 26 will be deformed, thereby driving the sliding frame 191, the auxiliary connecting frame 111, and the limiting block 27 to move to the right together until the sliding frame 191 is inserted by the limiting piece 24.

[0043] The auxiliary connecting frame 111 moving to the right will withdraw from the main connecting frame 110, so that a gap will appear on the right front side between the main connecting frame 110 and the auxiliary connecting frame 111, so that the connecting block 123 can pass freely, and the supporting frame 120 drives the seedling basin 113 and the guide wheel 21 to rotate to the top of the front main connecting frame 110, and the guide wheel 21 is aligned with the limiting block 27 on the front side. As the chain 119 drives the connecting block 123 to continue to rotate clockwise, the guide wheel 21 is engaged with the limiting block 27 on the front side, so that the supporting frame 120 is located directly above the main connecting frame 110. When the supporting frame 120 passes through the main connecting frame 110 on the front side, the seedling basin 113 on the supporting frame 120 will be caught by the main connecting frame 110 on the front side, so that the seedling basin 113 is transferred from the supporting frame 120 to the main connecting frame 110.

[0044] When the rotating extrusion member 22 is separated from the fixed member 23, under the elastic force of the reset spring 26, the movable member 25 will drive the fixed member 23, the sliding frame 191, the auxiliary connecting frame 111, and the limiting block 27 to move to the left and reset, and the auxiliary connecting frame 111 will be reinserted into the main connecting frame 110, and the sliding frame 191 will be disengaged from the limiting member 24. At this time, the main connecting frame 110 on the front side has been loaded, and the servo motor 18 can be controlled to drive the rotating rod 112 to rotate 45° clockwise. The main connecting frame 110 equipped with the seedling pot 113 will rotate to the bottom and contact the nutrient solution in the nutrient tank 16, so that the crops in the seedling pot 113 can be irrigated with the nutrient solution, and the uppermost main connecting frame 110 will rotate to the front, and the above operation will be repeated to fill the other main connecting frames 110 with the seedling pots 113.

[0045] When all the main connecting frames 110 are filled with seedling pots 113, the servo motor 18 can be controlled to drive the rotating rod 112 to rotate slowly, thereby driving the seedling pots 113 on the main connecting frame 110 to rotate slowly, thereby realizing rotary cultivation in the greenhouse. Conversely, when it is necessary to take out the seedling pots 113 from the main connecting frame 110, first align the empty placement rack 122 and place it on the connecting base 13, and then control the driving motor 121 to drive the rotating shaft 1151 to rotate counterclockwise. According to the previous steps, the chain 119 will drive the connecting block 123, the supporting frame 120, the guide wheel 21, and the extrusion piece 22 to rotate counterclockwise together, and the extrusion piece 22 will squeeze the fixing piece 23 again, and the auxiliary connecting frame 111 and the limiting block 27 will move to the right again, and the supporting frame 120 will rotate to the bottom of the front main connecting frame 110.

[0046] As the carrier 120 continues to rotate, the carrier 120 passes through the front main connecting frame 110, and the carrier 120 will clamp the seedling pot 113 on the main connecting frame 110 and take it away. When the guide wheel 21 contacts the guide member 2, the guide wheel 21 will drive the carrier 120 to align, so that the seedling pot 113 on the carrier 120 is placed in a vertical direction with the support base 1. When the carrier 120 clamping the seedling pot 113 passes through the U-shaped channel of the placement frame 122, the seedling pot 113 113 will fall on the placement rack 122. At this time, the seedling pot 113 will be transferred from the main connecting frame 110 to the placement rack 122. The staff can pick up the placement rack 122 and leave the greenhouse directly to continue subsequent operations. On the contrary, when the greenhouse needs to be dismantled, first remove the hook 14 from the supporting base 1, and then turn the adjusting screw rod 11 in the reverse direction to move the pressure rod 12 upward. The pressure rod 12 no longer presses the greenhouse cloth 1101, and finally the greenhouse cloth 1101 can be lifted from the arch frame 101.

[0047] To sum up, first, through the mutual cooperation of the extrusion member 22, the fixing member 23, the moving member 25, and the sliding frame 191, a flexible withdrawal mechanism is constructed. When taking and placing the seedling pot 113, it is ensured that the auxiliary connecting frame 111 component can automatically withdraw from the main connecting frame 110, thereby providing sufficient space for the supporting frame 120 component to automatically clamp or place the seedling pot 113. Secondly, through the mutual cooperation of the guide wheel 21, the guide member 2, and the limiting block 27, it is ensured that the supporting frame 120 always remains horizontal with the ground during the taking and placing process, effectively avoiding damage to the seedling pot 113 or crop damage caused by tilting or shaking. Then, through the mutual cooperation of the sprocket 116, the chain 119, and the placement frame 122, the automatic taking and placing of the seedling pot 113 by the supporting frame 120 is realized, which not only reduces the labor intensity of the operator, but also improves the degree of automation of the entire cultivation process.

[0048] Embodiment 2: Based on embodiment 1, Figure 12-14As shown, it also includes a correction mechanism for aligning the seedling pots 113 placed on the placement rack 122 in the horizontal direction. The correction mechanism is arranged on the connecting base 13, and the correction mechanism includes a connecting rod 33. The connecting rod 33 is fixedly connected to the left front side of the connecting base 13. The connecting rod 33 is rotatably connected to a rotating rod 32. The rotating rod 32 and the output shaft of the servo motor 18 are both fixedly connected to a transmission wheel 3. A transmission belt 31 is wound around the two transmission wheels 3. A main bevel gear 34 is fixedly connected to the right side of the rotating rod 32. A two-way screw rod 36 is rotatably connected to the left side of the connecting base 13. A slave bevel gear 35 is fixedly connected to the front side of the two-way screw rod 36. A center frame 37 symmetrically distributed front and back is threadedly connected to the two-way screw rod 36. The main bevel gear 34 and the slave bevel gear 35 are meshed with each other.

[0049] When the servo motor 18 drives the rotating rod 112 to rotate 45° clockwise, the servo motor 18 will also drive the rotating rod 32 to rotate through the transmission wheel 3 and the transmission belt 31, thereby driving the main bevel gear 34 to rotate. Since the main bevel gear 34 is engaged with the slave bevel gear 35, the bidirectional screw rod 36 is driven to rotate, so that the center frame 37 moves back and forth inward and outward. When the center frame 37 moves inward, if a seedling pot 113 is placed on the placement rack 122 at this time, the inward moving center frame 37 will contact the seedling pot 113, and the center frame 37 will give the seedling pot 113 a force toward the center, causing the seedling pot 113 to swing horizontally. The seedling basin 113 is aligned to ensure its accurate and stable position. The aligned seedling basin 113 provides great convenience for the subsequent pick-up and placement operations of the carrier frame 120. When the centering frame 37 moves outward, it breaks away from the contact state with the seedling basin 113, and is ready for the next inward movement and alignment operation. In summary, through the mutual cooperation of the transmission wheel 3, the transmission belt 31, the main bevel gear 34, the slave bevel gear 35, the bidirectional screw 36, and the centering frame 37, the seedling basin 113 can be automatically aligned and positioned, which facilitates the subsequent operation of the carrier frame 120 and improves the degree of automation and operating efficiency of the entire system.

[0050] like Fig.15 As shown, it also includes a limiting mechanism for preventing the seedling pot 113 on the supporting frame 120 from slipping off. The limiting mechanism is arranged on the supporting frame 120, and the limiting mechanism includes a fixed seat 41. The left side of the supporting frame 120 is fixedly connected with the fixed seat 41, the blocking rod 4 is rotatably connected to the fixed seat 41, and the reset torsion spring 42 is connected between the blocking rod 4 and the fixed seat 41, and the reset torsion spring 42 is wound around the blocking rod 4.

[0051] When the supporting frame 120 passes through the U-shaped channel of the placing frame 122, the blocking rod 4 on the supporting frame 120 will be resisted by the bottom plate of the placing frame 122, so that the blocking rod 4 will either flip up or flip down, and the reset torsion spring 42 will be twisted. When the blocking rod 4 rotates with the supporting frame 120 to separate from the placing frame 122, under the action of the reset torsion spring 42, the blocking rod 4 will either flip down or flip up to reset, and the blocking rod 4 will seal the opening on the left side of the supporting frame 120 to prevent the seedling pot 113 from slipping from the opening, thereby improving the stability and safety of the seedling pot 113 during the taking and placing process and reducing the operating risks and costs.
