Description

Technical Field

[0001] The utility model relates to the technical field of water and fertilizer management equipment, in particular to a device for precise water and fertilizer supply. Background Art

[0002] In the field of seedling planting, there is a considerable mortality rate for newly transplanted seedlings.

[0027] The electrical components appearing in the text are all electrically connected to the controller and the battery 10. The control method of the utility model is controlled by the controller. The control circuit of the controller can be realized by simple programming by technicians in this field. It belongs to the common knowledge in this field, so the utility model will not explain the control method and circuit connection in detail.

[0028] When in use, water and fertilizer are injected into the interior of the tank body 4 through the feed hopper 5, and then the first servo motor 91 is started by an external controller to drive the driving gear 92 to rotate, and then the driven gear 93 is used to drive the stirring shaft 7 and the stirring blade 8 to rotate, so as to stir and mix the water and fertilizer to form water-fertilizer. When it is necessary to supply water and fertilizer to the seedlings, the device can be moved to the side of the seedlings, and then the second servo motor 261 is started by an external controller to drive the worm 262 to rotate, and then the threaded rod 19 is driven to rotate through the worm gear 263. During the rotation process, the threaded rod 19 will drive the traction block 21 to move upward through the threaded sleeve 20, and then the piston 17 is driven upward through the traction rod 22, so that the water and fertilizer in the tank body 4 are drawn into the interior of the cylinder body 11 through the liquid inlet pipe 12. At the same time, the traction block 21 will also drive the mounting rod 23 and the pointer 24 to move upward during the upward movement. By observing the pointer 24 and The capacity scale 25 is used to control the amount of water and fertilizer in the cylinder 11 according to the demand of the seedlings until the amount of water and fertilizer in the cylinder 11 reaches the expected amount. When the pointer 24 points to the expected quantity value on the capacity scale 25, the second servo motor 261 can be turned off, and the liquid outlet end of the infusion hose 16 is aligned with the seedlings that need water and fertilizer replenishment, and then the second servo motor 261 is started to rotate in the opposite direction, thereby driving the threaded rod 19 to rotate in the opposite direction. At this time, the threaded rod 19 will drive the traction block 21, the traction rod 22 and the piston 17 to move downward as a whole during the rotation process, so as to transport the water and fertilizer in the cylinder 11 through the liquid outlet pipe 14 to the inside of the infusion hose 16 until the bottom of the piston 17 is in contact with the inner bottom wall of the cylinder 11, and finally the expected amount of water and fertilizer in the cylinder 11 is applied to the seedlings, thereby accurately controlling the amount of water and fertilizer applied, avoiding too little or too much water and fertilizer, and improving the survival rate of the seedlings as much as possible.

[0029] In summary, the device for precise water and fertilizer replenishment drives the worm 262 to rotate by starting the second servo motor 261, and then drives the threaded rod 19 to rotate through the worm gear 263. During the rotation of the threaded rod 19, the traction block 21 is driven to move upward through the threaded sleeve 20, and then the piston 17 is driven to move upward through the traction rod 22, so that the water and fertilizer in the tank body 4 are drawn into the interior of the cylinder body 11 through the liquid inlet pipe 12. At the same time, the traction block 21 will also drive the mounting rod 23 and the pointer 24 to move upward during the upward movement. By observing the pointer 24 and the capacity scale 25, the amount of water and fertilizer in the cylinder body 11 is controlled until the amount of water and fertilizer in the cylinder body 11 reaches the expected amount. When the pointer 24 points to the expected quantity value on the capacity scale 25, the second servo motor 261 can be turned off, and the liquid outlet end of the infusion hose 16 is aligned with the cylinder body 11 where water and fertilizer replenishment is required. The seedlings are then started, and the second servo motor 261 is started to rotate in the opposite direction, thereby driving the threaded rod 19 to rotate in the opposite direction. At this time, the threaded rod 19 will drive the traction block 21, the traction rod 22 and the piston 17 to move downward as a whole through the threaded sleeve 20 during the rotation, so as to transport the water and fertilizer in the cylinder 11 to the inside of the infusion hose 16 through the liquid outlet pipe 14, until the bottom of the piston 17 fits with the inner bottom wall of the cylinder 11, and finally the expected amount of water and fertilizer in the cylinder 11 is applied to the seedlings, thereby achieving the purpose of accurately controlling the amount of water and fertilizer applied, avoiding the situation of too little or too much water and fertilizer, and maximizing the survival rate of the seedlings. It solves the problem that in the actual operation process, water and fertilizer are often applied to the seedlings manually, so the amount of water and fertilizer applied cannot be accurately controlled, too little water and fertilizer will cause the fertilization effect to be unclear, and too much water and fertilizer will cause root burn and other problems.
