Background
With the continuous progress of science and technology, the value of berries such as medlar and the like is continuously explored, the effects of medlar polysaccharide rich in medlar on the aspects of oxidation resistance, aging resistance, fatigue resistance and the like are further verified, the market demand and the planting area of medlar are gradually expanded, and the medlar and medlar products form large-scale and industrialization with medlar characteristics.
However, fresh wolfberry fruit production has strong seasonality, particularly fresh wolfberry fruit harvesting has strong economical efficiency and short harvesting period, a large amount of manpower is required to be consumed to carry out traditional manual picking in the mature wolfberry fruit harvesting season, and the development of the wolfberry industry is greatly restricted by a large amount of labor requirements and a traditional manual picking mode.
There is also an operation mode of harvesting medlar by a harvesting machine. The medlar fruit tree has numerous disordered and soft fruit hanging branches except the trunk, the whole plant is in a drum shape with the middle protruding outwards, the fruit hanging branches are almost perpendicular to the ground, great difficulty is brought to harvesting, fresh medlar has thin skin and tender meat and is easy to be damaged by external force operation, the fruit yield is influenced, and during mechanical picking, the fruit yield is improved while the picking efficiency is ensured.
The existing medlar harvester mainly has an air suction type and an excitation type.
The air suction type medlar harvester sucks air in a suction pipe through a fan to generate negative pressure in the suction pipe, so that fruits are adsorbed. However, the air pressure is not easy to control during the specific implementation, and the phenomena of mistaken picking and fruit damage are easy to occur.
The excitation type medlar harvester acts on fruit branches through mechanical vibration generated by a certain excitation device on a walking device to cause the fruit branches to vibrate so as to accelerate movement, and when acting force applied to the fruit branches is larger than the binding force of the fruits and the fruit branches, the fruits (fruit bases) break at the fragile part connected with plants, so that the separation process is completed. In the harvesting process, the exciting force acts on the tree crown, the harvesting method is suitable for harvesting rattan fruits, branches of the dwarfed and densely planted Chinese wolfberry fruit trees are disordered and soft and are similar to the rattan forest fruits, and therefore the vibration harvesting method is suitable for harvesting the dwarfed and densely planted Chinese wolfberry fruit trees. In addition, the connection between the vibration excitation device and the walking device needs to have stronger reliability due to stronger mechanical vibration generated by the vibration excitation type medlar harvester.
Large dwarf close-planting forest fruit picking machines at home and abroad generally adopt a portal frame type and inverted U-shaped design, the picking machines are arranged at the upper ends of plants, the picking machines collect on two sides of the plants and collect by the ground. Door frame type picking machines such as application numbers 201610080517.5, 201711020323.7 and the like generally have larger volume and higher height and are inconvenient to transport; the excitation device is fixed in height, and is poor in suitability for medlar plants with variable heights; the harvesting width (harvesting width) of the whole machine is fixed, and the adaptability to the medlar orchard with variable row spacing is poor; one or two vibration excitation devices are assembled on the whole machine, one-time operation can only finish single-side harvesting of one or two lines of medlar fruit trees, and harvesting efficiency is low.
