Electric cherry picker with roller-slide-block manually-assisted non-contact mechanical hand

Abstract

The invention provides an electric cherry picker with a roller-slide-block manually-assisted non-contact mechanical hand. The picker comprises a handle, a support rod, a spring, a picking device and a collecting bag, wherein the spring, the support rod and the picking device are fixedly arranged on the handle; the support rod is hinged to the handle; the picking device is composed of a roller, a telescopic rod, a cutter and a spring which is a compression spring; one end of the telescopic rod is connected with the roller, and the other end of the telescopic rod penetrates through the spring and a through hole formed in the handle and is connected with the handle; one end of a connecting rod is fixed on the telescopic rod through a bolt, and the other end of the connecting rod is connected with a connecting plate of a motor through a bolt; the cutting edge of the cutter is provided with a plurality of concave small circular arcs; the outer circle surface of the roller is provided with a U-shaped groove. The handle is manually operated to turn on a power switch, accordingly the motor rotates and drives the cutter to reciprocate, the roller rotates on a cherry branch, the cutter cuts off cherry stalks, and the cherries fall into the collecting bag.

Description

technical field [0001] The invention relates to a roller slider artificially assisted non-contact manipulator electric cherry picker, which belongs to the technical field of agricultural machinery. Background technique [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 fro...

[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.
