Description

Technical Field

[0002] The integrated water-fertilizer machine is an agricultural machinery equipment that integrates irrigation and fertilization. It can automatically or semi-automatically complete irrigation and fertilization operations through mechanical, electronic and other means. It is widely used in the planting areas of field crops, vegetables, fruit trees and other planting areas in agricultural production. Different agents can be added to the integrated water-fertilizer machine according to planting needs to achieve different usage functions.

[0003] When adding auxiliary agents, it is usually necessary to manually pour the prepared agents into the medicine storage tank of the integrated water and fertilizer machine. This manual operation method has significant advantages. The type and amount of agents can be adjusted at any time according to actual needs. Different agents can be quickly replaced or added at different growth stages of crops or in different periods of pest control. In contrast, the traditional pipeline transportation system, once installed and fixed, needs to reconfigure or clean the pipeline system if the type of agent is changed or the amount is adjusted. The operation process is cumbersome and complicated, involving various electronic control adjustments, and is not suitable for integrated water and fertilizer machines with smaller usage requirements. However, the dosing port of the medicine storage tank of the integrated water and fertilizer machine is located high, and the manual dosing process is very inconvenient and requires climbing, which creates certain safety hazards.

[0026] The PLC controller 8 is fixedly mounted on the outer wall of the mobile lifting mechanism 2, and is electrically connected to the mobile lifting mechanism 2, the injection adding mechanism 3, the locking connection mechanism 4, the weighing feedback mechanism 5, the active control mechanism for the dosage 6 and the real-time statistical mechanism for the dosage 7.

[0027] The operating principle of the present invention is described as follows: put the prepared medicine into the preparation box ( Figure 1 The medicine storage tank 1 is provided with a liquid level sensor (not shown in the figure), which monitors the medicine storage amount in the medicine storage tank 1 in real time and feeds the monitoring data back to the PLC controller 8; When it is necessary to add medicine, the PLC controller 8 controls the first servo motor 64 to move based on the signal fed back by the liquid level sensor, and the first servo motor 64 drives the first transmission screw 62 to rotate. Through the threaded sleeve effect of the first transmission screw 62 and the adjustment plate 66, the adjustment plate 66 drives the in-place switch 67 to move upward, so that the in-place switch 67 moves away from the synchronization plate 68. Specifically, the less the amount of medicine in the medicine storage tank 1, the longer the action time of the first servo motor 64, the greater the distance the in-place switch 67 moves away from the synchronization plate 68, and the greater the interval between the in-place switch 67 and the synchronization plate 68. During the dosing process, the PLC controller 8 first controls the electric slide rail 21 to drive the injection adding mechanism 3 to move to the upper end of the configuration box, and then controls the bidirectional motor drive assembly 24 to drive the two rotating screws 23 to rotate synchronously (the bidirectional motor drive assembly 24 is specifically a double-axis motor with a gear structure to be connected to the rotating screw 23 for transmission, providing power output for the rotating screw 23). The threaded sleeve effect of the rotating screw 23 and the lifting plate 25 makes the lifting plate 25 drive the injection adding mechanism 3 to move downward, so that the feeding pipe 32 at the lower end of the adding shell 31 extends into the configuration box, and the PLC controller 8 controls the solenoid valve 33 on the feeding pipe 32 to open, and the PLC controller 8 controls the electric push rod 34 to drive the push-pull piston plate 35 to move upward, forming a negative pressure suction force in the adding shell 31, and sucking the configured medicine in the configuration box into the adding shell 31. After the electric push rod 34 drives the push-pull piston plate 35 to move up to the maximum stroke, the PLC controller 8 controls the solenoid valve 33 on the feeding pipe 32 to close, preventing The medicine leaks out (the feeding pipe 32 at the lower end of the adding shell 31 extends into the bottom of the configuration box to avoid the problem that the liquid level in the configuration box drops each time the suction affects the stable suction of the adding shell 31, ensuring that the amount of each extraction is fixed, and the liquid in the configuration box is set to be sufficient to meet the single addition amount to the medicine storage tank 1 to avoid the problem of insufficient medicine), the PLC controller 8 controls the bidirectional motor drive component 24 to move in the reverse direction again, cooperates with the lifting plate 25 to drive the injection adding mechanism 3 to move up to the upper side of the medicine storage tank 1, and controls The electric slide rail 21 drives the U-shaped moving plate 22 to move, so that the feeding pipe 32 at the lower end of the adding shell 31 moves to the feeding port at the upper end of the medicine storage tank 1. At this time, the PLC controller 8 controls the electric push rod 34 to push down the push-pull piston plate 35 and open the solenoid valve 33 on the feeding pipe 32, so that the feeding pipe 32 can feed the material. Under the pressure of the push-pull piston plate 35, the medicine in the adding shell 31 is quickly injected into the medicine storage tank 1, completing the adding work, and then repeating the above steps to perform continuous feeding-adding work; After the first inhalation of the medicine in the adding shell 31 is completed, the PLC controller 8 first controls the bidirectional motor drive assembly 24 to cooperate with the rotating screw 23 to move the adding shell 31 up to a certain height to prevent the configuration box from affecting the weighing position of the adding shell 31. The PLC controller 8 then controls the electric telescopic rod 44 in the locking connection mechanism 4 to drive the locking plate 45 and the locking rod 46 to move back, so that the locking rod 46 is disengaged from the insertion of the locking hole 47 on the side wall of the connecting plate 43, thereby releasing the limiting connection between the lifting plate 25 and the extension plate 36 on the outer wall of the adding shell 31. At this time, under the action of the self-weight of the injection type adding mechanism 3 and the medicine, the entire injection type adding mechanism 3 moves downward relatively along the positioning slide bar 51 to overcome the elastic force of the weighing spring 53, and is kept for 20 seconds to make the injection type adding mechanism 3 stable. Then, the PLC controller 8 controls the laser rangefinder 54 to work, and the laser rangefinder 54 detects the distance between the anti-slip plate 52 and the extension plate 36 to judge the weight of the medicine in the unit volume adding shell 31. Specifically, the greater the weight of the medicine in the unit volume adding shell 31, the greater the self-weight of the entire injection type adding mechanism 3. The greater the weight, the greater the distance that the weighing spring 53 can move downward, and thus the smaller the detection distance of the laser rangefinder 54. The laser rangefinder 54 feeds back the detected data signal to the PLC controller 8. The PLC controller 8 automatically adjusts the power of the electric slide rail 21 and the bidirectional motor drive assembly 24 in the mobile lifting mechanism 2 based on the feedback signal, so that the shorter the distance signal fed back by the laser rangefinder 54, the higher the working power of the electric slide rail 21 and the bidirectional motor drive assembly 24 is controlled, so as to better meet the stable transfer of the medicine and avoid the problem that the use of a smaller transfer power for an overweight medicine will cause the load of the entire mechanism to be too large, affecting the transfer rate. Based on the signal fed back by the laser rangefinder 54, the PLC controller 8 synchronously controls the subsequent push-pull power of the electric push rod 34 on the push-pull piston plate 35. When the weight of the medicine in the unit volume is greater, the working power of the electric push rod 34 is greater, because the greater the weight of the medicine in the unit volume, the greater the viscosity of the medicine, the greater the pushing resistance of the medicine, and the electric push rod 34 needs a greater working power to ensure the stable delivery of the medicine. After the weighing work is completed, the PLC controller 8 controls the power supply device to supply power to the suction electromagnetic plate 42. The suction electromagnetic plate 42 is energized to generate a magnetic force opposite to that of the suction permanent magnetic plate 41, thereby providing an attraction force to the extension plate 36, so that the extension plate 36 drives the adding shell 31 to move up and reset. At this time, the PLC controller 8 controls the electric telescopic rod 44 to move, so that the electric telescopic rod 44 pushes the locking plate 45 and the locking rod 46 outward, so that the locking rod 46 is again plugged into the locking hole 47 on the side wall of the connecting plate 43, completing the re-stable connection between the lifting plate 25 and the injection-type adding mechanism 3; Whenever the electric push rod 34 drives the push-pull piston plate 35 to move up to draw the medicine into the adding shell 31, the PLC controller 8 controls the second servo motor 65 to act synchronously, and the second servo motor 65 drives the second transmission screw 63 to rotate. Through the threaded sleeve action of the second transmission screw 63 and the synchronous plate 68, the synchronous plate 68 moves toward the in-position switch 67 in the control shell 61. After the electric push rod 34 drives the push-pull piston plate 35 to move up to the maximum stroke, the PLC controller 8 also controls the second servo motor 65 to pause, waiting for the next action of the electric push rod 34 to pull up the push-pull piston plate 35 to draw medicine. After multiple dosings, during the last addition shell 31 to draw medicine, when the synchronous plate 68 presses on the in-position switch After the switch 67 is closed, it indicates that the amount of medicine drawn has reached the total amount of medicine to be added. At this time, the PLC controller 8 synchronously controls the second servo motor 65 and the electric push rod 34 to stop the action, and the medicine drawn from the last adding shell 31 is transported to the medicine storage tank 1 again to complete the entire dosing work. The amount of medicine added can be automatically and accurately controlled and confirmed to ensure the quality of dosing, because the liquid level sensor calculates the amount of medicine injected into the medicine storage tank 1 based on the degree of change of the liquid level. However, when the medicine is added by pouring, the medicine is constantly fluctuating, which will affect the detection accuracy of the liquid level sensor. By directly counting the amount added each time, the amount of medicine added can be calculated more accurately, and the anti-interference ability is stronger, avoiding the problem of measurement errors. And every time the second transmission screw 63 rotates, the second transmission screw 63 will cooperate with the reduction gear box 71 and the bevel gear assembly 74 to drive the linkage shaft 73 to rotate synchronously at a reduced speed, so that the linkage shaft 73 drives the marking needle 75 to move relative to the annular drug dosage scale plate 76. The position of the annular drug dosage scale plate 76 corresponding to the marking needle 75 indicates the total amount of medicine that has been drawn, which is convenient for the staff to quickly know the total amount of medicine added.
