Non-contact type mechanical arm cherry picker with rollers and manual work assistance

Abstract

The invention provides a non-contact type mechanical arm cherry picker with rollers and manual work assistance. The non-contact type mechanical arm cherry picker comprises a handle, a supporting rod, a spring, a picker and a collection bag, wherein the spring, the supporting rod and the picker are fixed on the handle; the supporting rod is mounted on the handle and hinged with the same; the picker is formed by rollers, telescopic rods, springs and cutters; the springs are compressed springs; one end of each telescopic rod is linked with each roller and the other end passes through holes formed in the spring and the handle and is linked with the handle; one end of a connection rod is fixed on the telescopic rod via a bolt; the other end of the connection rod is linked with a rotary cutter via a bolt; a cutting edge of the rotary cutter is trapezoidal; a long bottom side of the trapezoid is close to the surface of a cherry branch; a U-shaped groove is formed on an excircle surface of each roller. The handle is assisted by manual work; the power supply is switched on, so the rollers rotate in cherry branches; the cutter is driven to cut off a cherry fruit handle; and cherries can fall into the collection bag.

Description

Technical field [0001] The invention relates to a roller artificial auxiliary non-contact manipulator cherry picker, which belongs to the technical field of agricultural machinery. Background technique [0002] Cherries have high sugar content and high water content. They are berries and have thin peels. There are six ways to pick cherries in our country. The first way is to pick directly from cherry branches by hand, which is inefficient and labor intensive. The second way A picking comb is used. Because cherries are rich in water and sugar, the cherries are located between the two comb teeth of the picking comb during picking. The power drives the comb teeth to rotate, and the cherries are separated from the stalk by pulling. The tensile strength of the cherry stalk Far greater than the tensile strength of cherries, and greater than the resistance to crushing of the peel. When the stalk is separated from the cherry, part of the peel or pulp of the cherry will fall off, causing ...

Problems solved by technology

[0002] Cherries have high sugar content and high water content. They belong to berries and have thin peels. There are six ways to pick cherries in China. The first way is to pick them directly from the branches of cherries by hand. The picking efficiency is low and the labor intensity is high. The second way Picking combs are used. Because cherries have a lot of water and high sugar content, the cherries are located between the two comb teeth of the picking comb when picking. The power drives the comb teeth to rotate, and the cherries are separated from the stalk by pulling. The tensile strength of the cherry stalk Far greater than the tensile breaking strength of cherries, and greater than the crushing resistance of the peel, when the stalk is separated from the cherry, part of the peel or pulp of the cherry will fall off, causing the loss of nutrients in the cherry, and the extrusion of the comb teeth on the surface of the cherry fruit will cause The skin is damaged and the surface is oxidized, which affects the quality of cherries. It is a destructive picking method. The third method is the air suction type. The air flow cannot enter between the clustered fruits. To achieve picking, the air-suction type determines that air-flow picking cannot be realized. The fourth method is the clamping type, and the surface produces relative movement, which seriously damages the surface of the cherry. The fifth method is the vibration and knocking type. , the outer surface is damaged by the action of gravity. The sixth method is the vibration picking of the eccentric block, which is a deformation of the vibration percussion type.
