[0033] refer to Figures 1-5 This embodiment provides an automatic tracking irrigation platform, comprising:

[0034] An automated tracking irrigation platform includes:

[0035] The irrigation vehicle body 10 has a walking wheel assembly 106 at the bottom, an integrated energy storage battery pack 105 and water pump 203 assembly in the middle, and an operation panel box 102 and a water spraying mechanism 20 at the top. The water spraying mechanism 20 includes a water suction pipe assembly 201, a water inlet and storage S-bend 203b of the water pump 203, a water outlet hose 202, an irrigation metal pipe 207, and an eccentric gravity spraying assembly 206. The water suction pipe assembly 201 includes a water inlet hose 204. A filter screen 205 is provided at the end of the water hose 204, and the other end of the hose is connected to the inlet 203a of the water pump 203. The inlet water storage S-bend 203b is located between the impeller of the water pump 203 and the inlet 203a. The outlet 203c of the water pump 203 is connected to one end of the outlet hose 202, and the other end of the outlet hose 202 is connected to the irrigation metal pipe 207. The irrigation metal pipe 207 is connected to the eccentric gravity spraying assembly 206.

[0036] The above-described structural design of the inlet water storage S-bend 203b of the water pump 203 allows a certain amount of water to be stored in the inlet water storage S-bend 203b when the pump is stopped (forming a water seal) to prevent air from entering the water inlet 203a of the water pump 203. When the pump is restarted, because water has been stored in the S-bend, air in the inlet hose 204 can be quickly discharged, preventing the impeller of the water pump 203 from being damaged by dry friction due to idling, thereby extending the service life of the seals; at the same time, the stored water can accelerate the water priming process and play an auxiliary role in venting.

[0037] The tracking and navigation system includes multiple sensors, and the signal output terminals of each sensor are electrically connected to the signal input terminals of the driving decision controller.

[0038] The drive transmission mechanism 30 includes a drive motor 301, a planetary gear multi-stage reducer 302, a drive wheel 303 gear ring, and a clutch lever assembly 304. The output end of the drive motor 301 is connected to the drive gear 305 through the planetary gear multi-stage reducer 302. The clutch lever assembly 304 can drive the drive reducer assembly to move up and down along the sliding groove 301a of the drive motor 301, thereby realizing the clutch switching between the drive gear 305 and the drive wheel 303 gear ring.

[0039] It should be noted that, in this embodiment,

[0040] The principle of clutch separation is as follows:

[0041] By pressing down the clutch lever 304a, the linkage drive reduction gearbox assembly moves downward along the sliding groove 301a of the drive motor 301, causing the drive gear 305 to disengage from the drive wheel 303 gear ring, cutting off the power connection between the drive motor 301 and the wheel, and enabling the platform to move freely.

[0042] The principle of clutch lock-up is as follows:

[0043] After the clutch lever 304a is unlocked, the drive reduction gearbox assembly moves upward and resets under the elastic force of the spring 304c of the adaptive drive motor 301, so that the drive gear 305 re-meshes with the gear ring of the drive wheel 303: when the drive motor 301 is working, it realizes self-driving; when the motor stops working, the gear meshing state can realize static parking lock to prevent the platform from sliding.

[0044] In this embodiment, the present invention designs a drive transmission mechanism 30, which controls the engagement and disengagement of the drive gear 305 and the gear ring through a clutch lever wrench 304a, thereby achieving the switching between drive mode and free push mode; furthermore, the present invention designs an S-bend design at the water inlet 203a of the water pump 203 to store water and prevent air from entering, thus extending the life of the seals.

[0045] It should be noted that, in this embodiment, the tracking and navigation system includes a forward-looking visual sensor, a rear-looking visual sensor, a dual-path forward ultrasonic radar, a rear-looking ultrasonic radar, and a driving decision controller.

[0046] Specifically, the eccentric gravity spraying assembly 206 includes a flat nozzle 206a, a spraying baffle 206b, and an eccentric counterweight 206c; wherein, the eccentric counterweight 206c is fixed at an asymmetrical position on the spraying baffle 206b, and the spraying baffle 206b is movably connected to the irrigation metal pipe 207 through a support lever structure, forming a reciprocating swing mechanism based on the impact force of water flow.

[0047] The well-known design principle of the eccentric gravity spraying component 206 is as follows: Irrigation water pumped by the water pump 203, carrying a certain pressure, travels through the irrigation pipe to the flat nozzle 206a and is sprayed out. A spraying baffle 206b installed at the flat nozzle 206a obstructs the sprayed irrigation water, causing the water column to be scattered in a parabolic shape. The spraying baffle 206b is set at a preset angle to the radial section of the water column axis, allowing it to deflect under the impact of the water flow; that is, water is sprayed under the impact force of the water column. The spray baffle 206b moves upward. When the spray baffle 206b passes the edge of the water column, the impact force from the deflection of the water column decreases. Under the action of the eccentric counterweight 206c and the lever force of the support, the spray baffle 206b moves downward. The spray baffle 206b repeats this back and forth, interfering with the water column sprayed from the flat nozzle 206a to spray out sprayed water droplets, increasing the spray coverage area and forming a spray irrigation surface perpendicular to the direction of movement, ensuring a certain spray irrigation coverage area and improving irrigation efficiency.

[0048] It should be noted that, in this embodiment, the water spray baffle 206b and the water outlet center axis of the flat nozzle 206a are deflected at an angle of 15°-30°.

[0049] In this embodiment, the present invention designs an eccentric gravity spraying component 206. Through the cooperation of the flat nozzle 206a, the spraying baffle 206b and the eccentric counterweight 206c, the spraying baffle 206b is deflected at an angle to the central axis of the water column. Under the action of the water flow impact force and the eccentric counterweight 206c, it reciprocates, increasing the spraying coverage area.

[0050] Specifically, the clutch lever assembly 304 includes a clutch lever wrench 304a, a clutch locking bracket 304b, and an adaptive drive motor 301 clamping spring 304c; wherein, the adaptive drive motor 301 clamping spring 304c is disposed between the drive motor 301 bracket and the irrigation vehicle body 10, and is used to maintain the meshing pressure between the drive gear 305 and the drive wheel 303 gear ring.

[0051] It should be noted that, in this embodiment, the clutch lever wrench 304a is linked to the drive reduction gearbox assembly to make vertical displacement along the sliding groove 301a of the drive motor 301.

[0052] refer to Figure 5 Specifically, the longitudinal central axis of the irrigation vehicle body 10 intersects with the horizontal plane where the rotation axis of the drive wheel 303 is located, together forming the gravity reference vertical line in the coordinate system. The energy storage battery pack 105 and the water pump 203 assembly are symmetrically distributed. The center of gravity of the whole machine is lower than the axis line of the walking wheel assembly 106, forming a stable and upright mechanical structure. This allows the whole platform to remain upright when it is parked or in operation. The water inlet hose 204 below can be bent and retracted upwards, solving the disadvantages of not touching the ground when the platform is parked and not being able to move it without dragging the ground when the site is moved.

[0053] It should be noted that, in this embodiment, the forward-looking visual sensor of the tracking navigation system is used to identify the yellow tracking line 5 on the ground, the dual-path forward ultrasonic radar is distributed at a 120° angle at the front of the vehicle body, and the driving decision controller generates drive control commands based on visual image recognition and ultrasonic ranging data to realize automatic navigation driving along a preset trajectory.

[0054] The inlet end of the water pump 203 inlet water storage S-bend 203b is connected to the outlet end of the filter screen 205 through an inlet hose 204. The outlet end of the water pump 203 inlet water storage S-bend 203b is sealed to the water pump 203 inlet 203a, forming a water seal structure to prevent air from entering.

[0055] It should be noted that, in this embodiment, the height difference of the curved section of the water inlet and water storage S-bend 203b of the water pump 203 is 10-15cm.

[0056] It should be noted that, in this embodiment, the water outlet cross-section of the flat nozzle 206a is a flattened oval shape, and the water spray baffle 206b is set at a preset angle to the radial section of the water column axis, which can deflect under the impact of water flow; the mass distribution of the eccentric counterweight 206c satisfies the following: when the water flow impact force is greater than the counterweight torque, the water spray baffle 206b swings upward past the water flow axis, and resets under the action of the counterweight after the impact force decreases, forming a periodic turbulent spraying action.

[0057] It should be noted that in this embodiment, the handrail 101 is set on the irrigation vehicle body 10, and its design conforms to the ergonomic principle, with a position and height that are convenient for the operator to hold; the handrail 101 is provided with an operation panel box 102, and the operation panel box 102 is provided with multiple operation buttons 104; a water baffle 103 is also provided above the operation panel box 102.

[0058] Working principle: The technical solution of this utility model mainly includes the following process.

[0059] I. Tracking and Driving Process

[0060] 1. After the platform is started, the forward-looking camera identifies the yellow tracking line 5 on the ground, the ultrasonic radar detects surrounding obstacles, and the signal is transmitted to the driving decision control box.

[0061] 2. The control box adjusts the speed and direction of the drive motor 301 according to the signal, so that the platform can move automatically along the yellow line and adapt to the direction of the water channel 4.

[0062] 3. The rear-view camera enables reverse driving and reciprocating tracking, allowing for repeated spraying and irrigation, which can improve work efficiency and reduce manpower input.

[0063] II. Irrigation Operation Process

[0064] 1. The suction pipe assembly 201 extends into the water channel 4, the filter screen 205 filters impurities, and the water flows through the inlet hose 204 into the water pump 203 inlet 203a. The water source is stored and air is removed by the water inlet storage S-bend 203b structure.

[0065] 2. The energy storage battery powers the motor of water pump 203. After the water pump 203 pressurizes the water, it is delivered to the irrigation metal pipe 207 through the outlet hose 202.

[0066] 3. Water is ejected from the flat nozzle 206a and impacts the water spray baffle 206b in front. Since the water spray baffle 206b is set at a preset angle to the radial section of the water column axis, it can deflect under the impact of the water flow. Therefore, the impact force of the water flow will cause the water spray baffle 206b to move upward. After passing the edge of the water column, the impact force decreases, and the water spray baffle 206b moves downward under the action of the eccentric counterweight 206c and the lever force. This process is repeated to disperse the water column into spray-shaped water droplets, forming a spray surface perpendicular to the direction of travel, covering the farmland.

[0067] III. Drive and Clutch Operation

[0068] 1. Self-driving: Unlock the clutch lever wrench 304a, the drive gear 305 engages with the drive wheel 303 gear ring, and the drive motor 301 drives the wheel to move through the reduction gearbox.

[0069] 2. Free to push: Pressing the clutch lever wrench 304a separates the drive gear 305 from the gear ring, allowing the platform to be moved manually, facilitating site relocation or position adjustment.

[0070] 3. Static parking: With the clutch locked, the platform remains stationary to prevent the vehicle from rolling away.

[0071] IV. Shutdown and Storage

[0072] After the operation is completed, turn off the water pump 203 and the drive system, and bend the water inlet hose 204 upwards and retract it. Since the center of gravity of the whole machine is located below the central axis and is balanced from left to right, the platform can be placed stably and upright, avoiding damage to the hose from touching the ground, and making it convenient for storage and transfer.

[0073] In summary, this utility model increases the spray coverage area through an eccentric gravity-driven spraying component, achieves switching between driven and free-push modes through a drive transmission mechanism, prevents air ingress by using an S-bend design for the water pump inlet and storage to extend the life of the seals, enables automatic driving through a tracking navigation system, and ensures stable upright operation through a well-designed center of gravity. This improves water resource utilization, equipment adaptability, and irrigation efficiency while reducing labor input. The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the technical principles of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model.
