Description

Technical Field

[0001] This invention relates to the field of agricultural machinery technology, specifically to a tracked self-propelled platform for transporting fertilizers / fruits. Background Technology

[0002] Most tropical fruits are grown in hilly areas. Traditional wheeled transport vehicles have poor maneuverability and stability, making them prone to tipping over, and frequent vibrations can easily damage the cargo (especially fruit). While some existing tracked transport vehicles improve maneuverability, their vibration reduction effect is limited. Furthermore, platform (cargo box) swaying during transport still requires manual intervention or low-speed driving to prevent it, resulting in low efficiency. In addition, cleaning the loading platform (if fruit baskets, fertilizer residue) after transport is tedious. Summary of the Invention

[0003] The purpose of this invention is to provide a tracked self-propelled fertilizer / fruit transportation platform to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, the present invention provides the following technical solution: A tracked self-propelled platform for transporting fertilizer / fruit includes: A rack, wherein the rack is provided with a storage platform; A walking assembly, comprising a drive mechanism and a walking mechanism, wherein the drive mechanism is used to drive the walking mechanism to move; A vibration energy recovery assembly includes a vibration damping mechanism, an air compression mechanism, and a storage mechanism. The vibration damping mechanism is used to reduce the vibration experienced by the frame. When the vibration damping mechanism is in use, it triggers the activation of the air compression mechanism, which is used to compress air when the vibration damping mechanism is working. The storage mechanism is used to store the air compressed by the air compression mechanism. The self-stabilizing component includes a detection mechanism and an active stabilizing mechanism. The detection mechanism is used to detect the stability of the storage platform, and the active stabilizing mechanism is driven by the air stored in the storage mechanism and is used to dynamically adjust the position of the storage platform. An exhaust cleaning assembly includes a storage tank and a pneumatic cleaning mechanism. The storage tank is used to store low-pressure air discharged by the active stabilizing mechanism, and the pneumatic cleaning mechanism is used to clean the storage platform using the air in the storage tank.

[0005] Preferably, the drive mechanism includes an engine and a drive axle. The engine is mounted on the frame and drives the drive axle to move. The drive axle is connected to the walking mechanism at both ends.

[0006] Preferably, the walking mechanism includes a protective shell and tracks, with the tracks connected to both ends of the drive axle, and the protective shell disposed on the outside of the tracks.

[0007] Preferably, the vibration damping mechanism includes a vibration damping spring, and the two ends of the vibration damping spring are respectively connected to the protective shell and the frame through ball joint connectors.

[0008] Preferably, the air compression mechanism includes a piston rod and a cylinder, the piston rod and the cylinder are respectively connected to different ball joint connectors, and the damping spring is sleeved on the outside of the piston rod.

[0009] Preferably, the storage mechanism includes a gas tank, which is disposed on the frame, and the cylinder is connected to the gas tank's inlet valve via a pipe.

[0010] Preferably, the detection mechanism includes an acceleration sensor, which is disposed on the storage platform and is used to detect the stability of the storage platform.

[0011] Preferably, the active stabilizing mechanism includes a pneumatic linear actuator and a connecting solenoid valve. The air inlet of the pneumatic linear actuator is provided with the connecting solenoid valve. The connecting solenoid valve and the air tank are connected to each other through a pipeline. There are three pneumatic linear actuators. The bottoms of the three pneumatic linear actuators are connected to the frame through ball joints, and the tops of the pneumatic linear actuators are connected to the bottom of the storage platform through ball joints.

[0012] Preferably, the pneumatic linear actuator is provided with an exhaust valve, which is connected to the storage tank. The pneumatic cleaning mechanism includes an electromagnetic opening valve and a retractable nozzle. The exhaust port of the storage tank is provided with the electromagnetic opening valve, which is connected to the retractable nozzle.

[0013] Compared with existing technologies, the beneficial effects of this invention are as follows: The combination of tracked walking and an active stabilization system makes this invention suitable for transportation operations on various uneven surfaces such as orchards and slopes. This invention recovers the originally dissipated vibration energy by converting the reciprocating motion of the vibration damping mechanism into compressed air, thus improving energy utilization efficiency. Simultaneously, the recovered energy drives the self-stabilization system, which actively counteracts platform sway caused by terrain, significantly improving the stability of the transportation process, reducing the risk of cargo damage, and allowing for appropriate increases in travel speed while ensuring safety. Furthermore, by collecting the low-pressure air discharged from the self-stabilization system again for cleaning, no additional power is required, achieving multi-level utilization of vibration energy and cleaning up spilled soil or fertilizer in the storage platform, saving time and effort.

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0017] Please see Figures 1-7 The present invention provides a technical solution: A tracked self-propelled fertilizer / fruit transport platform, as shown in the attached instruction manual. Figure 1 As shown, it includes the following organizations.

[0018] The machine frame 1 is equipped with a storage platform 2, which is used to store fertilizers or fruits that need to be transported.

[0019] The walking assembly includes a drive mechanism and a walking mechanism, the drive mechanism being used to drive the walking mechanism to move.

[0020] The vibration energy recovery component includes a vibration damping mechanism, an air compression mechanism, and a storage mechanism. The vibration damping mechanism is used to reduce the vibration experienced by the frame 1. When the vibration damping mechanism is in use, it triggers the activation of the air compression mechanism, which is used to compress air while the vibration damping mechanism is working. The storage mechanism is used to store the air compressed by the air compression mechanism.

[0021] The self-stabilizing component includes a detection mechanism and an active stabilizing mechanism. The detection mechanism is used to detect the stability of the storage platform 2, and the active stabilizing mechanism is driven by the air stored in the storage mechanism to dynamically adjust the position of the storage platform 2.

[0022] The exhaust cleaning assembly includes a storage tank 3 and a pneumatic cleaning mechanism. The storage tank 3 is used to store low-pressure air discharged by the active stabilizing mechanism, and the pneumatic cleaning mechanism is used to clean the storage platform 2 using the air in the storage tank 3.

[0023] The drive mechanism includes an engine 4 and a drive axle 5. The engine 4 is mounted on the frame 1 and drives the drive axle 5 to move. The two ends of the drive axle 5 are connected to the walking mechanism on both sides through half shafts, and the power is transmitted to the drive wheels of the track 7.

[0024] The traveling mechanism includes a protective shell 6 and tracks 7. The drive axle 5 is connected to the tracks 7 at both ends, and the protective shell 6 is located on the outside of the tracks 7.

[0025] The damping spring 8 in the damping mechanism is hinged at its upper and lower ends to the upper surface of the protective shell 6 of the traveling mechanism and the lower surface of the frame 1, respectively, via ball joint connectors. One end of the piston rod 9 of the air compression mechanism is fixedly connected to the lower ball joint connector, while the cylinder 10 body is fixedly connected to the upper ball joint connector, so that the extension and retraction of the damping spring 8 directly drives the piston to reciprocate within the cylinder 10. The air outlet of the cylinder 10 is connected to the air inlet valve of the air tank 11 of the storage mechanism via a high-pressure pipeline (the high-pressure pipeline is a flexible hose) equipped with a one-way valve.

[0026] The storage mechanism includes a gas tank 11, which is mounted on the frame 1. A cylinder 10 is connected to the air intake valve of the cylinder 10 via a pipe (the pipe is a flexible hose).

[0027] The detection mechanism includes an acceleration sensor 12, which is installed on the storage platform 2. The acceleration sensor 12 is used to detect the stability of the storage platform 2. The acceleration sensor 12 of the detection mechanism is installed at the center of the bottom of the storage platform 2, and its signal line is connected to the control system of the platform.

[0028] The active stabilizing mechanism includes pneumatic linear actuators 13 and connecting solenoid valves 14. The air inlet of each pneumatic linear actuator 13 is equipped with a connecting solenoid valve 14. The connecting solenoid valve 14 and the air tank 11 are interconnected via a pipe (a flexible hose). Three pneumatic linear actuators 13 are arranged, with their bottoms connected to the frame 1 via ball joints and their tops connected to the bottom of the storage platform 2 via ball joints. The three pneumatic linear actuators 13 of the active stabilizing mechanism are arranged in a triangular pattern between the bottom of the storage platform 2 and the frame 1. The air inlet of each pneumatic linear actuator 13 is connected to the main air supply line (a flexible hose) of the air tank 11 via an independent connecting solenoid valve 14. The opening and closing of the three connecting solenoid valves 14 are independently controlled by the control system based on signals from the acceleration sensor 12, thereby adjusting the extension and retraction of each pneumatic linear actuator 13.

[0029] The pneumatic linear actuator 13 is equipped with an exhaust valve 15, which is connected to the storage tank 3. The pneumatic cleaning mechanism includes an electromagnetic opening valve 16 and a retractable nozzle 17. The exhaust port of the storage tank 3 is equipped with the electromagnetic opening valve 16, and one end of the electromagnetic opening valve 16 is connected to the retractable nozzle 17. The exhaust ports of the three pneumatic linear actuators 13 are respectively connected to different storage tanks 3. The electromagnetic opening valve 16 at the outlet of the storage tank 3 is controlled by the control system, and its outlet is connected to the retractable nozzle 17, which is located at the bottom of the storage platform 2.

[0030] Working Principle: When the platform travels, the impact caused by uneven ground is transmitted through the tracks 7 and the traveling mechanism, causing the protective shell 6 to vibrate relative to the frame 1. Some of the vibration is absorbed by the damping springs 8, and the reciprocating motion of the damping springs 8 drives the piston rod 9 to compress air in the cylinder 10. The compressed air is stored in the air tank 11 through a one-way valve, completing the recovery of vibration energy into air pressure potential energy. The acceleration sensor 12 on the storage platform 2 monitors its attitude in real time. When tilting or excessive vibration is detected, the control system controls the opening and closing of the solenoid valve 14 of the corresponding pneumatic linear actuator 13, introducing compressed air from the air tank 11 into the actuator, pushing the piston rod 9 to extend and retract, thereby quickly adjusting the storage platform 2 back to a horizontal and stable state. During the adjustment process, the low-pressure air discharged by the pneumatic linear actuator 13 is collected in the storage tank 3. When storage platform 2 requires cleaning (e.g., after unloading), the control system activates the pneumatic cleaning mechanism, opening the electromagnetic valve 16 at the outlet of storage tank 3. The stored low-pressure air is then ejected at high speed through nozzles, cleaning the surface of storage platform 2 of any spilled fertilizer or fallen soil. The entire system achieves closed-loop automatic operation of energy recovery, dynamic stability adjustment, and waste utilization and cleaning during operation.
