Remote-control self-walking gas-suction comb-picking revolving-bowl conveyor-belt type sorting and grading pear picking machine

Abstract

The invention provides a remote-control self-walking gas-suction comb-picking revolving-bowl conveyor-belt type sorting and grading pear picking machine comprising a trolley, a gasoline generator, a motor, a hydraulic pump, a comb picker, a conveying mechanism, and a grading and sorting mechanism. Walking wheels are arranged on one end face of the frame of the trolley, and rotation wheels are arranged on the other end face. Elevation cylinders are arranged on the frame of the trolley. The elevation cylinders stretch, and drive a platform to elevate. The gasoline generator, the motor, the hydraulic pump, and a collection box are arranged on the platform. The gasoline generator provides power for the motor. The hydraulic pump drives the double-power elevation cylinders to elevate. The comb picker comprises a picking comb and a comb motor. An induced draft fan is arranged at the conveyor belt at a place close to the comb picker end. When the machine is in use, a moving handle is held and the comb picker is moved close to pear branches. The induced draft fan sucks air, and a pear stalk is turned from a dropping shape into a horizontal shape. The comb motor drives the picking comb to rotate. The pears fall from the branches and drop into bowls arranged on the conveying mechanism. The bowls revolve with the belt, and the pears fall into the collection box for grading and sorting.

Description

technical field [0001] The invention provides a remote-controlled self-propelled air-suction comb picking rotating bowl conveyor belt-type pear picking machine for sorting and grading, which belongs to the technical field of agricultural machinery. Background technique [0002] There is a long history of planting pears in our country, and there are many varieties. Pear trees are perennial trees. The trees grow densely and tall, and their height exceeds the height of a person. Every year when pears are ripe, they are picked manually. Pears are juicy fruits. , to prevent bruising and damage, affecting storage and commodity value. When picking, pears that can be touched by people are picked directly, and those that cannot be touched are picked by a ladder. People stand on the ladder to pick, and the picked pears are placed in the backpack on the chest. Inside, different picking positions require changing the position of the ladder many times. Standing on the ladder for a long t...

Problems solved by technology

[0003] The purpose of this invention is to provide a method that can overcome the shortcomings of simple manual operation, high labor intensity, and time-consuming and labor-intensive work when picking pears. Pulling, so that the pear stems and branches fall off, picked by air suction combing, simulating the action of human hands, the airflow of the induced draft fan changes the pear stems from drooping to deviate from the vertical line, and the angle between the pear and the plumb 45°, driven by the power, the picking comb is composed of plastic comb teeth, the distance between the comb teeth is smaller than the diameter of the pear, and a flexible sleeve is installed on the comb teeth. In order to prevent the pear from being damaged, it is transported by a rotating bowl. The interior is filled with flexible materials, and the picking at different heights can be achieved through the lifting of the oil cylinder. The picking efficiency is high. In order to reduce the weight, the picking picker and fan are made of injection molded parts.
