Description

Technical Field

[0001] This invention relates to the field of agricultural machinery, and in particular to a tracked, vibration-damping, ditching, fertilizing, and soil-covering integrated machine for hilly orchards. Background Technology

[0002] Due to the undulating terrain and narrow row and plant spacing, large agricultural machinery is difficult to operate in orchards in hilly and mountainous areas of my country. Ditching and fertilization mainly rely on manual labor, which is inefficient and labor-intensive. Developing integrated ditching and fertilization equipment suitable for the complex terrain of hilly orchards is a key issue that urgently needs to be addressed in orchard mechanization. Existing ditching and fertilization machinery mainly uses pure wheeled or pure tracked mechanisms. Wheeled chassis offer fast transfer speeds and flexible steering, but are prone to slipping on soft ground and have poor maneuverability; tracked chassis have low ground pressure and good field maneuverability, but are slow to move and have poor road adaptability. This makes it difficult to meet the efficient application requirements of "operation + transfer" in hilly orchards. In terms of ditching operations, traditional ditchers experience high working resistance and energy consumption when cutting soil, especially under heavy clay soil conditions. Existing drag reduction methods mainly rely on optimizing the geometric parameters of the cutting tools, but the drag reduction effect is limited. Vibration drag reduction technology, by generating high-frequency vibrations in soil-contacting components, can alter soil shear states and reduce cutting resistance. This technology has been validated in single processes such as deep tillage, but its application in integrated ditching and fertilization equipment remains unexplored. In summary, existing ditching and fertilization equipment for hilly orchards still has significant shortcomings in terms of terrain adaptability of the walking mechanism, ditching drag reduction capabilities, and functional integration. There is an urgent need to develop an integrated system that combines good maneuverability and rapid relocation capabilities, incorporates vibration drag reduction ditching functions, and can complete ditching, fertilization, and soil covering operations in a single operation. Summary of the Invention

[0003] The purpose of this invention is to overcome the shortcomings of the prior art and provide a wheel-tracked vibration-damping ditching, fertilizing and soil-covering integrated machine for hilly orchards, so as to solve the problems of poor terrain adaptability, high ditching resistance and high energy consumption, and low functional integration of existing hilly orchard ditching and fertilizing equipment.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: A wheel-tracked vibration-damping ditching, fertilizing, and soil-covering integrated machine for hilly orchards includes a main frame, a wheel-tracked electric chassis, a drive mechanism, an energy mechanism, a vibration-damping ditching device, and a fertilizing device. The drive mechanism, energy mechanism, vibration-damping ditching device, and fertilizing device are all mounted on the main frame. The drive mechanism is used to drive the vibration damping trenching device, and the energy mechanism is used to provide power to the wheeled electric chassis, drive mechanism, vibration damping trenching device and fertilization device. The wheeled electric chassis includes a track mechanism and a wheel mechanism. The wheel mechanism and the track mechanism are respectively hinged to horizontal rotating shafts at the front and rear of the lower end of the main frame, and can rotate in a vertical plane. A connecting spring is provided between the wheel mechanism and the main frame. The vibration damping trenching device is provided between the track mechanism and the wheel mechanism, and a mudguard is provided at the lower end of the main frame surrounding the vibration damping trenching device. The mudguard is used to prevent soil from splashing. After the soil is blocked, it falls down to complete the covering. The vibration damping trenching device includes a fixed base, a chain trenching cutter device, and a damping spring. The chain trenching cutter device is horizontally mounted on the fixed base for chain trenching. The damping spring is vertically positioned between the fixed base and the chain trenching cutter device. One end of the damping spring is hinged to the fixed base, and the other end is hinged to the chain trenching cutter. A pneumatic vibration block is provided in the middle of the chain trenching cutter device. The pneumatic vibration block is used to drive the chain trenching cutter device to vibrate in the vertical direction. The damping spring is used to dampen and buffer the vibration. A fertilization device is installed at the rear end of the main frame, which is used to apply fertilizer after the trenching is completed.

[0005] Furthermore, the wheels in the wheel mechanism are omnidirectional wheels.

[0006] Furthermore, the pneumatic vibration block is fixed on the grooving cutter of the chain grooving cutter device.

[0007] Furthermore, the fertilization device includes an electric push rod, an electric fertilizer box, a fertilizer bin, a square frame, an inner fertilizer tube, and an outer fertilizer tube. One end of the electric push rod is hinged to the square frame via a pin, and the other end is hinged to the outer fertilizer tube via a pin. The electric fertilizer box and the fertilizer bin are connected to the square frame via bolts. The outer fertilizer tube is nested on the inner fertilizer tube, and the square frame is fixed on the main frame.

[0008] Furthermore, the mudguard is U-shaped with its opening facing the front of the main frame.

[0009] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. This invention adopts a wheeled track chassis. When the machine turns, the front track differentially steers, and the rear universal wheel follows, making the steering sensitive. When traveling in hilly orchards, when encountering uneven ground, the articulated wheeled track electric chassis can adaptively adjust the angle between the triangular track frame and the main frame, which can make the track ground contact area large and the grip strong. The whole machine is adaptable to hilly and mountainous terrain, with strong stability and passability.

[0010] 2. This invention adopts a power configuration that uses a wheeled electric chassis, an electric-driven fertilization device, and a hydraulically driven trenching operation, which reduces operating costs, simplifies operation, and ensures the quality of operation.

[0011] 3. This invention employs a vibration damping device. A pneumatic vibrating block provides a periodic force perpendicular to the chain trenching cutter. The tip of the chain trenching cutter generates a periodic amplitude, which can change the soil shear state, effectively reduce cutting resistance, and reduce trenching energy consumption. When the trenching cutter encounters hard soil blocks or stones, the damping springs on both sides absorb the instantaneous load through compression deformation, thereby reducing the vibration and impact of the machine and ensuring the stability of trenching operations in hilly orchards.

[0012] 4. This invention integrates trenching and fertilization functions, resulting in a high degree of overall machine integration. Attached Figure Description
