[0031] like Figure 1As shown, the present invention discloses a fertilizer applicator, including a fertilizer applicator body 200. The fertilizer applicator body 200 includes a frame 14, a control circuit system 3, a first drive mechanism, a second drive mechanism, a material hopper 16, and a material throwing disc 8. The material hopper 16 is installed on the frame 14, and a material gate 10 is provided at the bottom of the material hopper 16. The material throwing disc 8 is located below the material gate 10.

[0032] The control circuit system 3 is electrically connected to the first drive mechanism, and the first drive mechanism is connected to the material gate 10. The control circuit system 3 is used to issue instructions to the first drive mechanism, and the first drive mechanism drives the material gate 10 to open or close according to the received instructions.

[0033] The control circuit system 3 is electrically connected to the second drive mechanism, and the second drive mechanism is connected to the material throwing disk 8. The control circuit system 3 is used to issue commands to the second drive mechanism, and the second drive mechanism drives the material throwing disk 8 to rotate according to the received commands.

[0034] The sling plate 8 spreads fertilizer using centrifugal force generated by its rotation, controlling the fertilization width and ensuring even fertilization.

[0035] The frame 14 is made of aluminum alloy and is the main body of the equipment carrier.

[0036] The material hopper 16 is used to store solid materials (fertilizer), and the material hopper 16 is preferably made of plastic material.

[0037] The first driving mechanism is a gate servo motor 11, which controls the opening size of the gate 10. The gate 10 preferably adopts a double-door scissor-type opening method to work in conjunction with the gate servo motor 11, which can change the control of the discharge size according to the flight speed to ensure accurate fertilizer application per area.

[0038] The second drive mechanism includes a brushless motor 5 and a drive belt 6, wherein the brushless motor 5 is connected to the material throwing disc 8 via the drive belt 6. The brushless motor 5 is 7kW.

[0039] The second drive mechanism also includes a brushless ESC 2, which is connected to both the control circuit system 3 and the brushless motor 5. Upon receiving commands from the control circuit system 3, the brushless ESC 2 controls the brushless motor 5. The function of the brushless ESC 2 is to supply power to the brushless motor 5 and control its speed and operation upon receiving on / off and speed commands from the control circuit system 3. The main advantages of the brushless ESC 2 are its small size, adjustable output power, and light weight.

[0040] The fertilizer applicator body 200 also includes a communication module 4, which is connected to the control circuit system 3. The function of the communication module 4 is to receive commands such as the generator switch from the helicopter cockpit and transmit various signals to the control circuit system 3.

[0041] The function of the control circuit system 3 is to receive various instructions from the communication module 4 and control the working status of the brushless ESC 2 and the material gate servo motor 11 accordingly, and transmit relevant working status data back to the transmitter in the helicopter cockpit.

[0042] The fertilizer applicator body 200 also includes a distance and altitude measuring system 9. This system measures the distance between the fertilizer applicator and obstacles directly in front of it, as well as the fertilizer applicator's height above the ground, thus obtaining distance and altitude measurement data. The system wirelessly transmits this data to the helicopter, where it is displayed on the helicopter's screen. In emergency situations, such as when the fertilizer applicator is too close to an obstacle (distance less than a set value) or too low above the ground (height less than a set value), the system transmits a release signal to the hook actuator circuit. The hook actuator circuit then controls the release mechanism to disengage, ensuring flight safety.

[0043] The fertilizer applicator body 200 also includes a lithium battery 7, which is used to power the control circuit system 3, the second drive mechanism, and the distance and height measuring system 9.

[0044] The fertilizer applicator body 200 also includes a guide plate 12 and a guide plate rod 13. The guide plate 12 is connected to the frame 14, and one end of the guide plate rod 13 is connected to the frame 14, while the other end of the guide plate rod 13 is connected to the guide plate 12. The guide plate 12 functions to prevent the equipment from rotating or swaying left or right under the action of wind resistance at a certain flight speed, thus providing orientation and stability. The guide plate rod 13 functions to stabilize and adjust the wind resistance during high-speed flight.

[0045] The fertilizer applicator body 200 also includes a foot shock absorber 1, which is installed at the bottom of the frame 14. The foot shock absorber 1 has a built-in pressure spring, and its main function is to reduce the impact force generated when the aircraft lands the fertilizer applicator on the ground due to the influence of landing speed, altitude, environmental conditions, etc., so as not to damage the fertilizer applicator body 200.

[0046] The material hopper 16 is provided with a feeding port, and the feeding port of the material hopper 16 is provided with a feeding port cover 15. The feeding port cover 15 ensures that the fertilizer is not blown outward by the wind field during operation.

[0047] The fertilizer applicator body 200 also includes a lifting lug 17, which is connected to the frame 14.

[0048] The fertilizer applicator body 200 also includes a base frame, which is connected to the frame 14. The control circuit system 3, the first drive mechanism, the second drive mechanism, and the material throwing disc 8 are installed on the base frame.

[0049] The fertilizer applicator also includes a release device 100 and a hook body execution circuit. In an emergency, the distance and height measuring system 9 transmits a release signal to the hook body execution circuit, which then controls the release device 100 to separate.

[0050] like Figure 3 As shown, the unhooking device 100 includes an upper hook body 102 and a lower hook body 106. The lower hook body 106 is provided with a hook 107. The unhooking device 100 also includes a limiting connection mechanism for locking or separating the upper hook body 102 and the lower hook body 106.

[0051] The limiting connection mechanism includes a limiting component, a locking mechanism 103 and a driving mechanism installed on the upper hook body 102. The lower hook body 106 is provided with the limiting component. The driving mechanism is connected to the locking mechanism 103. The driving mechanism is used to drive the locking mechanism 103 to move. The locking mechanism 103 can achieve limiting engagement and separation with the limiting component.

[0052] The locking mechanism 103 includes a connecting rod 1031 and a protrusion 1032 connected to the connecting rod 1031. The driving mechanism is a motor 105, which is connected to the connecting rod 1031 and drives the connecting rod 1031 to rotate. The limiting component is a groove 1061 provided on the lower hook body 106. When the protrusion 1032 rotates into the groove 1061, the protrusion 1032 and the groove 1061 engage in a limiting cooperation, thereby locking the upper hook body 102 and the lower hook body 106. When the protrusion 1032 rotates out of the groove 1061, the protrusion 1032 separates from the groove 1061, thereby separating the upper hook body 102 and the lower hook body 106.

[0053] In a preferred embodiment of the unhooking device 100, there are two locking mechanisms 103, two motors 105, and two grooves 1061. The two motors 105 are respectively connected to the two connecting rods 1031, and each motor 105 drives the two connecting rods 1031 to rotate. When the two protrusions 1032 rotate into the two grooves 1061, they engage with the grooves 1061 to lock the upper hook body 102 and the lower hook body 106. When the two protrusions 1032 rotate out of the grooves 1061, they separate from the grooves 1061, separating the upper hook body 102 and the lower hook body 106. The unhooking device 100 also includes a spring 104 connected to the two connecting rods 1031.

[0054] The unhooking device 100 also includes a retaining ring 101 connected to the upper hook body 102, the retaining ring 101 being used for connection to the helicopter.

[0055] like Figure 2 As shown, a release device 100 is installed at the bottom of the helicopter, and a steel cable is attached to the release device 100 and connected to the lifting lug 17 of the fertilizer applicator body 200.

[0056] During assembly, when the separated lower hook body 106 is inserted into the upper hook body 102, the end of the lower hook body 106 will push against the locking mechanism 103 and separate outwards. The locking mechanism 103 returns to its original position under the tension of the spring 104, and the protrusion 1032 is embedded in the groove 1061, thereby locking the upper hook body 102 and the lower hook body 106. Figures 4 to 7 As shown, Figure 7 This is the normal operating state. If the operator issues a disengagement command, or if the operator fails to take appropriate obstacle avoidance measures in an emergency and is still unable to detach from the obstacle, the ranging and height measuring system 9, based on the set minimum safe distance, issues a forced automatic disengagement command to separate the hoisting equipment. In this case, the motor 105 starts working, pulling the locking mechanism 103 downwards. Figure 8 As shown; the lower hook body 106 detaches. Figure 9 and Figure 10 The fertilizer applicator body is completely separated from the aircraft to ensure flight safety.

[0057] The above description, in conjunction with specific preferred embodiments, provides a further detailed explanation of the present invention. It should not be construed that the specific implementation of the present invention is limited to these descriptions. For those skilled in the art, various simple deductions or substitutions can be made without departing from the concept of the present invention, and all such modifications and substitutions should be considered within the scope of protection of the present invention.
