Description

Technical Field

[0001] The invention belongs to the technical field of fertilization devices, and in particular relates to liquid fertilizer precise proportioning irrigation fertilization equipment and an implementation method thereof. Background Art

[0002] Liquid fertilizer precision ratio irrigation fertilization equipment is an efficient and accurate agricultural fertilization technology product, which can achieve rapid ratio and fertilization of multiple types of fertilizers. This equipment plays a vital role in modern agriculture, especially in promoting smart agriculture and improving water and fertilizer utilization.

[0003] However, the existing liquid fertilizer precision proportioning irrigation fertilization equipment has the following disadvantages: 1. Although the existing fertilization equipment can proportion fertilizer and water, it consumes a lot of manpower and material resources when using it, and is relatively inconvenient to operate. Secondly, after weighing the fertilizer, the existing proportioning device cannot automatically drive the fertilizer to be poured into the fertilizer box, which makes the overall automation effect of the device relatively poor;

[0004] 2. After the existing fertilizing device pours the fertilizer and water into the fertilizing box, the fertilizer and water cannot be mixed quickly. In addition, the mixing effect of the fertilizer in the existing fertilizer mixing device is relatively poor, and the stirring area of ​​the stirring rod is relatively small, so it cannot meet the purpose of quickly mixing the fertilizer and water.

[0005] 3. After the fertilizer is mixed, the existing fertilization device cannot spray the fertilizer quickly. Secondly, the height and angle of the nozzle cannot be adjusted, so the overall fertilization efficiency of the fertilization device cannot achieve good results.

[0006] 4. Most of the existing fertilization devices have multiple sets of universal wheels at the bottom to drive the device to move. However, after the fertilization device is moved to a specified position, the stability of the fertilization device during use cannot be guaranteed.

[0018] Furthermore, a method for implementing a liquid fertilizer precise proportioning irrigation and fertilization device comprises the following steps:

[0019] S1: In order to ensure that the liquid fertilizer can achieve precise quantitative proportioning, first set the amount of water added (through the liquid level sensor) through the PLC controller for monitoring, and then set the amount of fertilizer added (through the weighing sensor) for monitoring. At this time, slowly pour water into the water storage bin and observe through the scale. When the amount of water injected reaches the threshold of the liquid level sensor set by the PLC controller, the liquid level sensor converts the monitoring signal into an electrical signal and transmits it to the PLC controller. The PLC controller controls the solenoid valve to open, thereby realizing the water addition work, and then pour the fertilizer into the storage bin until the fertilizer falls on the weighing plate inside the charging box. When the amount of fertilizer added reaches the threshold of the weighing sensor set by the PLC controller, the PLC controller controls the motor to work, driving the charging box to flip, thereby realizing the fertilizer addition work;

[0020] S2: The ear plate on the side of the fixed plate is fixed to the side of the storage bin by bolts. When the motor drives the loading box to flip, it will also drive the rotating shaft to rotate. The rotation of the rotating shaft will drive the rotating plate to rotate. The rotation of the rotating plate will drive the fixed column to rotate counterclockwise. At this time, the inclined surface of the inclined plug-in block located inside the slot is at the top. When the fixed column rotates, it will drive the inclined plug-in block to compress the square limit plate and the spring to embed into the inside of the installation slot together, until the rotating shaft drives the fixed column to rotate to the baffle. Due to the existence of the baffle, the loading box is just flipped 180 degrees at this time. After the fertilizer is added, the output shaft of the motor is controlled by the PLC controller to rotate in the opposite direction. At this time, the rotating shaft drives the rotating plate and the fixed column to rotate clockwise. When the inclined plug-in block is aligned with the slot again, the spring rebounds, thereby driving the inclined plug-in block to be inserted into the slot again. Since the lower end surface of the inclined plug-in block is complete, the inclined plug-in block cannot continue to slide downward, so that the motor can drive the loading box to automatically reset.

[0021] S3: When fertilizer and water are added to the fertilization box, the second motor is turned on. The second motor drives the second rotating shaft to rotate through the output end. When the second rotating shaft rotates, it drives the first bevel gear inside the installation box to rotate. The first bevel gear rotates and drives the second bevel gear to rotate. The second bevel gear rotates and drives the first stirring shaft to rotate. The first stirring shaft rotates and drives the first stirring rod to rotate. The first stirring shaft rotates and drives the first transmission gear to rotate. The first transmission gear rotates and drives the first flexible toothed belt to rotate. The first flexible toothed belt rotates and drives the second transmission gear to rotate. The second transmission gear rotates and drives the second stirring shaft to rotate. The second stirring shaft rotates and drives the second stirring rod to rotate, thereby fully mixing the fertilizer and water.

[0022] S4: By turning on the liquid pump, the liquid pump extracts the liquid fertilizer in the fertilizer box through the liquid pumping pipe, and then sends it into the nozzle body through the discharge pipe for spraying. When the height of the nozzle body needs to be adjusted, the motor three at the upper end of the vertical plate one is turned on, and the motor three drives the screw rod one to rotate through the output end, and the rotation of the screw rod one drives the transmission gear three to rotate, and the rotation of the transmission gear three drives the flexible toothed belt two to rotate, and the rotation of the flexible toothed belt two drives the transmission gear four to rotate, and the rotation of the transmission gear four drives the screw rod two to rotate, and the rotation of the screw rods one and two drives the nut block to rise and fall, and the lifting of the nut block drives the lifting of the U-shaped seat, and the lifting of the U-shaped seat can drive the height of the nozzle body to be adjusted;

[0023] S5: When adjusting the angle of the nozzle body, pull the handle, the handle pulls the rod, the rod pulls the circular limit plate and the fixing rod, so that the fixing rod slides out from the inside of the fixing hole, and the circular limit plate drives the second spring to compress. At this time, turn the turntable, the turntable drives the rotating rod to rotate, and the rotation of the rotating rod can drive the angle of the nozzle body to be adjusted. After the adjustment is completed, release the handle, the second spring rebounds, thereby driving the fixing rod to be inserted into another set of fixing holes to achieve the positioning of the nozzle body;

[0024] S6: The device can be moved to a specified position through the universal wheel at the lower end of the base, and then motor four is turned on. Motor four drives the driving rod to rotate through the output end, and the driving rod rotates to drive bevel gear three, and the bevel gear three rotates to drive bevel gear four, and the bevel gear four rotates to drive the threaded rod to rotate. The threaded rod rotates to drive the lifting plate to descend, and the lifting plate descends to drive the support seat to descend until it contacts the ground. When the lifting plate descends, it drives the slider to slide out of the slide slot, thereby improving the stability of the lifting plate during the lifting process. When the support seat contacts the ground, the contact area between the base and the ground will increase, thereby improving the stability of the device during use.

[0025] Compared with the prior art, the present invention has the following beneficial effects:

[0026] 1. The present invention is provided with a material quantitative proportioning mechanism, which can facilitate accurate quantitative proportioning of fertilizer and water. At the same time, the liquid level sensor and the weighing sensor can be used to monitor the amount of material respectively, and then the solenoid valve and the fertilizer dumping component are controlled by the PLC controller to add the material into the interior of the fertilizer box for subsequent mixing.

[0027] 2. The present invention is provided with a fertilizer mixing mechanism, which can facilitate the sufficient mixing of the fertilizer and water in the fertilization box, so that it is convenient to extract the wastewater mixture through the water pump and spray it out through the nozzle later, avoiding the problem that the liquid pump cannot effectively extract the wastewater mixture.

[0028] 3. The present invention is provided with a fertilizing mechanism, which can facilitate the extraction of fertilizer from the fertilizer box and then spray it out through the nozzle. Secondly, the mechanism can adjust the installation height of the nozzle and the spraying angle of the nozzle, thereby improving the fertilization efficiency of the device.

[0029] 4. The present invention is provided with a moving mechanism, which can facilitate the movement of the device through the universal wheel. When the device moves to the specified position, the support base can be driven down to contact the ground through the mechanism to increase the contact area between the base and the ground, thereby ensuring that the vibration generated by the device during fertilization will not cause a large deviation between the device and the ground.

[0044] By adopting the above technical solution, in order to ensure that the liquid fertilizer can achieve precise quantitative proportioning, first, the amount of water added is set by the PLC controller 411 (through the liquid level sensor 49) for monitoring, and then the amount of fertilizer added is set (through the weighing sensor 41) for monitoring. At this time, water is slowly poured into the water storage bin 47 and observed by the scale 48. When the amount of water injected reaches the threshold of the liquid level sensor 49 set by the PLC controller 411, the liquid level sensor 49 converts the monitored signal into an electrical signal and transmits it to the PLC controller 411. The PLC controller 411 controls the solenoid valve 410 to open, thereby realizing the water addition work, and then the fertilizer is poured into the interior of the storage bin 44 until the fertilizer falls on the weighing plate 43 inside the charging box 45. When the amount of fertilizer added reaches the threshold of the weighing sensor 41 set by the PLC controller 411, the PLC controller 411 controls the motor 1 46 to work, driving the charging box 45 to flip, thereby realizing the fertilizer addition work.

[0045] The present invention further comprises a fertilizer dumping assembly 42 comprising a fixed disk 421, a baffle 422, a rotating shaft 423, a rotating plate 424, a bolt 425, an ear plate 426, a spring 427, a fixed column 428, a mounting groove 429, a slot 4210, an inclined plug block 4211 and a square limit plate 4212. A rotating shaft 423 is provided on the other side of the charging box 45. A fixed disk 421 is sleeved on the surface of the rotating shaft 423. An ear plate 426 is provided on the side of the fixed disk 421. The ear plate 426 is fixedly connected to the storage bin 44 by bolts 425.

[0046] By adopting the above technical solution, the ear plate 426 on the side of the fixed disk 421 is fixed to the side of the storage bin 44 by the bolt 425. When the motor 46 drives the charging box 45 to flip, it will also drive the rotating shaft 423 to rotate. The rotation of the rotating shaft 423 will drive the rotating plate 424 to rotate. The rotation of the rotating plate 424 will drive the fixed column 428 to rotate counterclockwise. At this time, the inclined surface of the inclined plug block 4211 located inside the slot 4210 is at the top. When the fixed column 428 rotates, it will drive the inclined plug block 4211 to compress the square limit plate 4212 and the spring 427 and embed them into the inside of the installation slot 429 until the rotating shaft 423 drives the fixed column 428 to rotate to When the baffle 422 is at the position, due to the existence of the baffle 422, the charging box 45 is just turned over 180 degrees. After the fertilizer is added, the output shaft of the motor 46 is controlled by the PLC controller 411 to rotate in the opposite direction. At this time, the rotating shaft 423 drives the rotating plate 424 and the fixed column 428 to rotate clockwise. When the inclined plug 4211 is aligned with the slot 4210 again, the spring 427 rebounds, thereby driving the inclined plug 4211 to be inserted into the interior of the slot 4210 again. Since the lower end surface of the inclined plug 4211 is intact, the inclined plug 4211 cannot continue to slide downward, so that the motor 46 can drive the charging box 45 to automatically reset.

[0047] When the present embodiment is used, in order to ensure that the liquid fertilizer can achieve precise quantitative proportioning, the amount of water added is first set by the PLC controller 411 (through the liquid level sensor 49) for monitoring, and then the amount of fertilizer added is set (through the weighing sensor 41) for monitoring. At this time, water is slowly poured into the water storage tank 47 and observed by the scale 48. When the amount of water injected reaches the threshold of the liquid level sensor 49 set by the PLC controller 411, the liquid level sensor 49 converts the monitoring signal into an electrical signal and transmits it to the PLC controller 411. The PLC controller 411 controls the solenoid valve 410 to open, thereby realizing the water adding work, and then pouring the fertilizer into the storage bin 44 until the fertilizer falls on the weighing plate 43 inside the charging box 45. When the amount of fertilizer added reaches the threshold value of the weighing sensor 41 set by the PLC controller 411, the PLC controller 411 controls the motor 46 to work, driving the charging box 45 to flip, thereby realizing the fertilizer adding work. The ear plate 426 on the side of the fixing plate 421 is fixed to the side of the storage bin 44 by the bolt 425.

The rotating plate 424 rotates to drive the fixed column 428 to rotate counterclockwise. At this time, the inclined surface of the inclined plug block 4211 located inside the slot 4210 is at the top. When the fixed column 428 rotates, it drives the inclined plug block 4211 to compress the square limit plate 4212 and the spring 427 and embed them into the installation groove 429. Until the rotating shaft 423 drives the fixed column 428 to rotate to the baffle 422, due to the existence of the baffle 422, the loading box 45 is just turned 180 degrees at this time. After the fertilizer is added, the output shaft of the motor 46 is controlled by the PLC controller 411 to rotate in the opposite direction. At this time, the rotating shaft 423 drives the rotating plate 424 and the fixed column 428 to rotate clockwise. When the inclined plug 4211 is aligned with the slot 4210 again, the spring 427 rebounds, thereby driving the inclined plug 4211 to be inserted into the slot 4210 again. Since the lower end surface of the inclined plug 4211 is intact, the inclined plug 4211 cannot continue to slide downward, so that the motor 46 can drive the charging box 45 to automatically reset.

The stirring shaft 2 86 is arranged on the other side of the lower end of the transmission structure 85, and the stirring shaft 2 87 is arranged on the surface of the stirring shaft 2 86.

[0050] By adopting the above technical solution, when fertilizer and water are added to the interior of the fertilization box 2, the motor 2 84 is turned on, and the motor 2 84 drives the rotating shaft 2 83 to rotate through the output end.

At this time, first slowly pour water into the water storage bin 47 and observe through the scale 48. When the amount of water injected reaches the threshold of the liquid level sensor 49 set by the PLC controller 411, the liquid level sensor 49 converts the monitored signal into an electrical signal and transmits it to the PLC controller 411.

[0072] S6: The device can be moved to a specified position through the universal wheel 7 at the lower end of the base 1, and then the motor four 611 is turned on. The motor four 611 drives the driving rod 612 to rotate through the output end, and the driving rod 612 rotates to drive the bevel gear three 613 to rotate, and the bevel gear three 613 rotates to drive the bevel gear four 614 to rotate, and the bevel gear four 614 rotates to drive the threaded rod 66 to rotate, and the threaded rod 66 rotates to drive the lifting plate 64 to descend, and the lifting plate 64 descends and drives the support seat 65 to descend until it contacts the ground.

At this time, water is first slowly poured into the water storage tank 47, and observed through the scale 48.
