Description

Technical Field

[0001] The invention relates to the technical field of transplanting bag cultivation, and in particular to a transplanting bag cultivation device and a cultivation method for alfalfa in a high-cold pastoral area. Background Art

[0002] Alfalfa is native to western Asia. It is a perennial herb of the Leguminosae family. It is rich in protein, vitamins and trace nutrients. Poultry and livestock gain weight quickly after eating it. It is known as the "king of forage" and is deeply favored by breeders. Alfalfa cultivation in high-altitude pastoral areas mostly adopts the cultivation technology that combines modern intelligent greenhouse seedling cultivation with field transplanting package cultivation. It is divided into three stages: "indoor seedling cultivation-indoor and outdoor adaptability training-field transplanting package cultivation". Weak seedlings, diseased seedlings, etc. are eliminated, and strong seedlings are selected. This not only retains the superior quality of alfalfa forage, but also has the adaptability to growth in high-altitude pastoral areas.

A telescopic shaft is slidingly clamped in the middle of the bottom end of the retractable outer cylinder, and the bottom end of the telescopic shaft and the top end of the slide seat are fixedly mounted.

[0014] A method for cultivating alfalfa in transplanting bags in high-cold pastoral areas comprises the following steps:

[0015] Step 1: Position and clamp the new alfalfa transplanting bag to be cultivated on its positioning slide, and connect the end of the liquid inlet pipe to the feed end of the nutrient solution guide pump mechanism;

[0016] Step 2: Control and start the first linear electric cylinder to drive the drip irrigation assembly and the seedling replacement mechanism to move, so that the drip irrigation assembly corresponds to one row of multiple transplanting bags. Then, according to the amount of drip irrigation, control and start the first motor to drive the rotating shaft to rotate, thereby driving the control cylinder to perform stable micro-rotation in the drip irrigation outer cylinder, and then drive the control groove to perform micro-rotation. The control groove and the dropper are staggered to adjust the size of the flux at the top of the dropper. Then, control and start the electric lifting rod to drive the slide frame to slide vertically in the corresponding longitudinal slide, drive the drip irrigation outer cylinder and multiple droppers to slide vertically, adjust the height position of the multiple droppers, and place the droppers above the corresponding transplanting bags. Then, start the nutrient solution liquid guide pump mechanism, and the nutrient solution is input into the drip irrigation outer cylinder and the control cylinder through the liquid inlet pipe, and quantitatively enters the corresponding multiple regulating droppers from the multiple control grooves and the top of the corresponding regulating droppers, and is discharged from the bottom of the regulating droppers, so as to perform precise quantitative drip irrigation on the multiple transplanting bags in the row below.

[0017] Step 3: During drip irrigation, observe whether there is bad alfalfa that needs to be automatically selected and replaced. When bad alfalfa is encountered, control and start the second linear electric cylinder to drive the contraction outer cylinder, the telescopic shaft, and the seedling replacement mechanism to move horizontally, so that the seedling replacement mechanism moves to the position of the bad alfalfa. Again, control the electric lifting rod to lower the height of the seedling replacement mechanism so that one of the positioning slides that does not clamp the new alfalfa moves to the top of the bad alfalfa, and the corresponding two L-shaped clamps move to the two sides of the corresponding transplanting bag port. Then, control and start the second motor to drive the first gear drive The crown gear rotates, thereby driving one of the double-headed screws to rotate, and cooperates with the connection of the connecting shaft to drive the other double-headed screw to rotate synchronously, thereby synchronously driving the two L-shaped clamps on both sides to slide toward each other, and the alfalfa transplanting bag is clamped and positioned by sliding toward each other through the anti-skid pads at the bottom. Subsequently, the seedling replacement mechanism is moved up to lift the bad alfalfa transplanting bag for selection. When the bad alfalfa is automatically selected, the sealing plate moves to the bottom of the dropper above the corresponding bad alfalfa, and the dropper is movably connected to the sealing groove to block the dropper, so as not to affect the drip irrigation of other alfalfas;

[0018] Step 4. When the bad alfalfa transplanting bag is automatically moved up to be picked up for selection, the rotating column and the second gear are moved up synchronously, and the second gear is meshed with one side of the rack. Subsequently, the seedling changing mechanism is driven to move, the rotating column and the second gear are moved, and the rack drives the second gear and the rotating column to rotate, thereby driving the bad alfalfa transplanting bag and the new alfalfa transplanting bag to rotate and swap positions, so that the new alfalfa transplanting bag is automatically swapped to the original bad alfalfa transplanting bag position. Subsequently, the seedling changing mechanism is moved down, the second gear is disengaged from the rack, and the seedling changing mechanism is driven to move again, and the new alfalfa transplanting bag is moved to the original position of the bad alfalfa transplanting bag. The seedling changing mechanism is moved down again to place the new alfalfa transplanting bag on the storage rack, and the bad alfalfa is automatically selected and the new alfalfa is automatically replaced.

8. A method for cultivating alfalfa in alpine pastoral areas by transplanting bags according to any one of claims 1 to 7, characterized in that: The steps include: Step 1: Position and clamp the new alfalfa transplanting bag to be cultivated on its positioning slide (67), and connect the end of the liquid inlet pipe (10) to the feed end of the nutrient solution liquid guide pump mechanism; Step 2: Control and start the first linear electric cylinder (3) to drive the drip irrigation assembly (5) and the seedling replacement mechanism (6) to move, so that the drip irrigation assembly (5) corresponds to one row of multiple transplanting bags (21). Then, according to the amount of drip irrigation, control and start the first motor (543) to drive the rotating shaft (542) to rotate, thereby driving the control cylinder (54) to perform a stable micro-rotation in the drip irrigation outer cylinder (52), and then drive the control groove (541) to perform a micro-rotation, and the control groove (541) and the drip tube (53) are staggered to adjust the size of the flux at the top of the drip tube (53). Then, control and start the electric lifting rod (41) to drive the carriage frame (51 ) slides vertically in the corresponding longitudinal slide frame (4), driving the drip irrigation outer cylinder (52) and the plurality of drip tubes (53) to slide vertically, adjusting the height positions of the plurality of drip tubes (53) so that the drip tubes (53) are placed above the corresponding transplanting bag (21), and then the nutrient solution liquid guide pump mechanism is turned on, the nutrient solution is input into the drip irrigation outer cylinder (52) and the control cylinder (54) through the liquid inlet pipe (10), and quantitatively enters the corresponding plurality of regulating drip tubes (53) from the plurality of control grooves (541) and the top of the corresponding regulating drip tubes (53), and is discharged from the bottom of the regulating drip tubes (53), so as to accurately and quantitatively drip irrigate the plurality of transplanting bags (21) in a row below; Step 3: During drip irrigation, observe whether there is any bad alfalfa that needs to be automatically selected and replaced. When bad alfalfa is encountered, control and start the second linear electric cylinder (71) to drive the contraction outer cylinder (81), the telescopic shaft (82), and the seedling replacement mechanism (6) to move horizontally, so that the seedling replacement mechanism (6) moves to the position of the bad alfalfa. Again, control the electric lifting rod (41) to lower the height of the seedling replacement mechanism (6) so that one of the positioning slides (67) that does not clamp new alfalfa moves above the bad alfalfa, and the corresponding two L-shaped clamps (672) move to the two sides of the corresponding transplanting bag (21) port. Then, control and start the second motor (68) to drive the first gear (681) to drive the crown gear ( 682) rotates, thereby driving one of the double-headed screws (673) to rotate, and cooperates with the connection of the connecting shaft (674) to drive the other double-headed screw (673) to rotate synchronously, thereby synchronously driving the two L-shaped clamps (672) on both sides to slide towards each other, and the alfalfa transplanting bag is clamped and positioned by sliding the anti-skid pad (675) at the bottom towards each other, and then the seedling replacement mechanism (6) is moved up to lift the bad alfalfa transplanting bag for selection. When the bad alfalfa is automatically selected, the sealing plate (64) moves to the bottom of the dropper (53) above the corresponding bad alfalfa, and the dropper (53) is movably connected to the sealing groove (641) to block the dropper (53), so as not to affect the drip irrigation of other alfalfa; Step 4: When the damaged alfalfa transplanting bag is automatically lifted up for selection, the rotating column (651) and the second gear (652) are synchronously moved up, and the second gear (652) is meshed with one side of the rack (9). Subsequently, the seedling replacement mechanism (6) is driven to move, the rotating column (651) and the second gear (652) are moved, and the rack (9) drives the second gear (652) and the rotating column (651) to rotate, thereby driving the damaged alfalfa transplanting bag and the new alfalfa transplanting bag to rotate and replace. The new alfalfa transplanting bag is automatically replaced to the position of the original damaged alfalfa transplanting bag. Subsequently, the seedling replacement mechanism (6) is moved downward, the second gear (652) is disengaged from the rack (9), and the seedling replacement mechanism (6) is driven to move again, and the new alfalfa transplanting bag is moved to the position where the damaged alfalfa transplanting bag was originally placed. The seedling replacement mechanism (6) is moved downward again, and the new alfalfa transplanting bag is placed on the storage rack (2), and the damaged alfalfa is automatically selected and replaced with the new alfalfa.
