Description

Technical Field

[0001] This invention relates to a vibratory harvester, and more particularly to a lightweight, tracked vibratory harvester suitable for steep mountainous terrain. Background Technology

[0002] my country's fruit tree industry is well-developed, but most of the trees are planted in mountainous and hilly areas. Due to the rugged terrain and tall trees, harvesting is difficult, inefficient, time-consuming, and costly. Chinese patent CN118923340A discloses a lightweight and simple vibratory harvester that can clamp the tree trunk at multiple points. It has a simple structure, is electrically assisted, and can be used in harvesting environments such as slopes and hills. It includes a vehicle body and a vibration clamping mechanism. The vehicle body includes an H-shaped bottom composed of two longitudinal beams and a crossbeam. The lower ends of two vertically extending guide rods are fixed above the rear of the two longitudinal beams. The suspension platform is located above the front of the two longitudinal beams, and the rear of the suspension platform is fixed to a sliding frame, which is slidably mounted on the guide rods. A lifting drive device for driving the suspension platform or sliding frame to move up and down relative to the guide rods is connected to the suspension platform or sliding frame. The vibration clamping mechanism for clamping the tree trunk and vibrating it is suspended from the drive suspension platform by a flexible rope. The above devices use hub-driven electrical systems, which are poorly adapted to hilly areas and have difficulty crossing steep slopes. Because the vibration clamping mechanism uses belt drive, the belt is prone to coming off during vibration, resulting in unstable vibration transmission and unsatisfactory vibration effect.

The outer peripheral surface of the backrest wheel 2-3 contacts the guide rod 1-3. The four hook pulleys 2-8 are slidably connected to the front of the suspension frame 2-9. The upper part of the flexible chain 2-7 is movably connected to the lower part of the hook pulleys 2-8, and the lower part is connected to the vibration clamping mechanism 3.

[0031] In this example, the front of the suspension frame 2-9 is symmetrically provided with sliding frame slots 2-91, and the hook pulley 2-8 can slide in the slot, so that the vibration clamping mechanism can move back and forth a certain range, which is convenient for clamping the tree trunk. It can be used in harvesting environments where the bottom of the tree is shaded.

[0032] In this example, the vibration clamping mechanism 3 includes a support plate 3-1, a clamping hydraulic cylinder 3-2, a movable clamping plate 3-3, an excitation assembly 3-4, a fixed clamping plate 3-5, a fixed clamping plate folding plate 3-6, and a clamping rubber pad 3-7. The support plate 3-1 is respectively equipped with the fixed clamping plate 3-5, the movable clamping plate 3-3, and the clamping hydraulic cylinder 3-2. The lower part of the fixed clamping plate 3-5 is fixedly connected to the support plate 3-1, and the lower parts of the movable clamping plate 3-3 and the clamping hydraulic cylinder 3-2 are rotatably connected to the support plate. The head of the fixed clamping plate 3-5 is provided with a fixed clamping plate folding plate 3-6. 6 is detachably connected to the fixed clamping plate 3-5 via a pin; the clamping rubber pads 3-7 are respectively fixedly connected to one side of the support plate 3-1, the movable clamping plate 3-3, the fixed clamping plate 3-5, and the fixed clamping plate folding plate 3-6; the upper part of the clamping hydraulic cylinder 3-2 is rotatably connected; when the movable clamping plate 3-3 approaches the fixed clamping plate folding plate 3-6 under the drive of the clamping hydraulic cylinder 3-2, the fixed clamping plate 3-5, the fixed clamping plate folding plate 3-6, the support plate 3-1, and the movable clamping plate 3-3 form a quadrilateral or pentagon; the vibration assembly 3-4 is fixedly installed at the rear of the support plate 3-3.

[0033] In this example, the excitation assembly 3-4 includes a power unit, a transmission unit, and an excitation mechanism. The power unit is a gasoline engine 3-45. The transmission components include a reducer 3-46 and a coupling 3-47. The excitation mechanism includes an excitation housing 3-43, an eccentric block 3-41, an excitation shaft 3-42, and an excitation cover plate 3-44. The reducer input port is connected to the gasoline engine 3-45 via a reducer adapter, and the reducer output port is connected to the coupling 3-47 via a reducer output shaft. The ends are connected by a key; eccentric block 3-41 is arranged on excitation shaft 3-42, eccentric block 3-41 and excitation shaft 3-42 are arranged in excitation housing 3-43, excitation housing 3-43 is fixedly connected to excitation cover plate 3-44; the excitation cover plate 3-44 presses against the tapered roller bearing that mates with excitation shaft 3-42, the other end of excitation shaft 3-42 is placed outside excitation housing and connected to coupling 3-47 by a key; excitation housing is fixed on support plate 3-1.

[0034] The coupling described in this example is a flexible coupling, which avoids the interruption of excitation caused by belt slippage during vibration due to belt connection, and the large change in excitation frequency caused by unstable belt movement during excitation. It can also prevent the excitation force of the excitation mechanism from being transmitted to the reducer and gasoline engine, thus avoiding damage to the gasoline engine.

[0035] In use, first move the harvester to a suitable position so that the trunk is between the fixed clamping plate 3-5 and the movable clamping plate 3-3. Adjust the lifting hydraulic cylinder 2-4 to make the vibration clamping mechanism 3 reach the target excitation height. First, bring the fixed clamping plate 3-5 close to the trunk, then fix the fixed clamping plate folding plate 3-7 to the fixed clamping plate 3-5 with two pins to increase the overall envelopment of the trunk. The fixed clamping plate folding plate 3-5 is not installed at first, or it is only rotatably connected to the fixed clamping plate 3-5 with one pin and the fixed clamping plate folding plate 3-6 is in an outward folded state. The fixed clamping plate 3-5 and the movable clamping plate 3-3 are in a staggered position. The trunk is opened to allow entry into a larger diameter tree trunk. The clamping hydraulic cylinder 3-2 is adjusted to clamp the trunk. The clamping hydraulic cylinder 3-2 pushes the moving clamping plate 3-3, so that the trunk is wrapped by the fixed clamping plate 3-5, the fixed clamping plate folding plate 3-6, the moving clamping plate 3-3, and the support plate 3-1. When the moving clamping plate 3-3 is bent, the fixed clamping plate 3-5, the fixed clamping plate folding plate 3-6, the two sides of the bent moving clamping plate 3-3, and the support plate 3-1 form a pentagon. When the moving clamping plate 3-3 is straight, the fixed clamping plate 3-5, the fixed clamping plate folding plate 3-6, the moving clamping plate 3-3, and the support plate 3-1 form a quadrilateral, thus completing the clamping.

[0036] Power is transmitted from the gasoline engine 3-45, which reduces speed and increases torque through the reducer 3-46, and drives the excitation shaft 3-42 to rotate through the flexible coupling 3-47, thereby causing the eccentric block 3-41 to rotate and generate excitation force. This harvesting device can obtain ideal vibration frequency and excitation force, has strong environmental adaptability, can provide continuous energy input, has low labor intensity, high harvesting efficiency, and is suitable for mountainous areas, with high harvesting efficiency, good stability, and convenient mobility.
