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

Abstract

The invention provides an electric persimmon 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 persimmon branch, the cutter cuts off persimmon stalks, and the persimmons fall into the collecting bag.

Description

technical field [0001] The invention relates to a roller slider artificially assisted non-contact manipulator electric persimmon picker, which belongs to the technical field of agricultural machinery. Background technique [0002] Persimmon is a kind of fleshy berry. The outer skin of mature persimmons is soft. After bruises and falls, the pulp will flow out, and the surface will oxidize and turn black. When picking, try to avoid damage to the outer skin. There are many ways to pick persimmons at home and abroad. The first is The method is to directly grab the persimmons by hand, and the persimmons are separated from the fruit handle, so the picking efficiency is low and the labor intensity is high. The second method is the hook knife type, which is aligned with the persimmons and directly grabbed by the hook knife to pick the persimmons. The third method is Comb-teeth type, the persimmons are located between the two comb teeth of the picking comb when picking, the comb teet...

[0002] Persimmon is a kind of fleshy berry. The outer skin of mature persimmons is soft. After bruises and falls, the pulp will flow out, and the surface will oxidize and turn black. When picking, try to avoid damage to the outer skin. There are many ways to pick persimmons at home and abroad. The first is The method is to directly grab the persimmons by hand, and the persimmons are separated from the fruit handle, so the picking efficiency is low and the labor intensity is high. The second method is the hook knife type, which is aligned with the persimmons and directly grabbed by the hook knife to pick the persimmons. The third method is Comb-teeth type, the persimmons are located between the two comb teeth of the picking comb when picking, the comb teeth of the picking comb are in contact with the skin of the persimmon, and the comb teeth and the surface of the persimmon produce mutual squeezing force, and the skin of the persimmon is easily damaged during the rotation of the comb teeth , the surface of the damaged persimmons is oxidized and blackened, which affects the quality of picking and the quality of the persimmons. The fourth method is the shaking type, which uses the reciprocating motion of the eccentric four-bar mechanism to force the persimmons to fall off, which is a destructive method of picking. During the falling process, acceleration is generated, and when they hit the ground, they collide with each other and damage the outer skin, which seriously damages the persimmon tree and affects the growth and yield of several trees in the next year. The fifth method is the clamping type. force, slippage occurs, the clamping force is too large, the persimmon is deformed, the skin is broken, and the clamping position is very important
