Description
Technical field
The present invention relates to a kind of preparation method of sealing ring, and in particular to a kind of preparation of the sealing ring of fruit picker mechanical arm
Method.
Background technology
Fruit refers to succulence and most of pleasantly sweet fruits that can directly eat it raw, not only containing abundant nutrition and
It can help digest.Fruit is the general designation of the fruit edible to part and seed.Fruit has hypotensive, slows down and decline
Always, the health-care effect such as weight-reducing, skin care, improving eyesight, anticancer, reduction cholesterol replenishing vitamins.Fruit contains human body must
The nutrient such as multivitamin, mineral matter, carbohydrate, crude fibre, protein and fat needed, it is not only tasty to eat fruit,
And health can be promoted, and then the purpose of disease preventing and treating.
With the horizontal development of agricultural science and technology and the increase of social demand, the plantation of various fruit is also more and more, is water
Fruit planting household brings considerable economic benefit, but its fruit flies the important process that harvest and planting households are faced, its
The harvesting of fruit is a large amount of artificial generally by using, and by manually carrying out, it needs manually to carry out using some ascending tools
Artificial harvesting, the species of fruit is a lot, including apple, pears, orange, coconut, shaddock etc., apple, pears, orange, coconut,
The fruit such as shaddock, its picking method fully rely on artificial harvesting at present, and the fruit that growth position exceedes labour's height will use ladder
Son carries out operation, and efficiency is low, and extremely hazardous, and the situation that injury is thrown from ladder happens occasionally, so as to add harvesting work
The harvesting difficulty of people and the danger that unexpected injury occurs.
Fruit picker be exclusively used in high-altitude harvesting fruit use, telescopic mechanical arm be fruit picker necessary component it
One, mechanical arm is flexible by mutually splicing realization, and seal washer is needed to use between two mechanical arms mutually spliced, existing
Seal washer is annular packing ring, and sealing effectiveness is bad.
The content of the invention
The present invention proposes a kind of preparation method of the sealing ring of fruit picker mechanical arm regarding to the issue above, is prepared
Sealing ring good sealing effect, service life length.
Specific technical scheme is as follows：
A kind of preparation method of the sealing ring of fruit picker mechanical arm, its step are as follows：
