Agricultural high fruit picking device

Abstract

The invention discloses an agricultural high fruit picking device comprising a two wheel trolley. A lifting mechanism is movably connected to the upper portion of the two wheel trolley and is movably connected to a console; the console is movably connected to one end of a telescopic arm, the other end of the telescopic arm is movably connected to a balance mechanism, the top of the balance mechanism is connected to a shearing arm, and the bottom of the balance mechanism is connected to an accommodating bag. According to the device, the two wheel trolley replaces of a power transport vehicle to be adaptive to poor driving condition of an orchard; the telescopic arm replaces of a mechanical arm with multiple freedom degrees, weight is decreased, structure and control of the arm are simplified, and the moving space of the arm is saved; the suspended soft bag replaces of a fixed fruit conveying channel, the fruit conveying distance is shortened, and fruit damage is reduced; the device is more adaptive to the application for the orchard.

Description

technical field [0001] The invention belongs to the technical field of fruit picking devices, and relates to an agricultural high-position fruit picking device. Background technique [0002] The most commonly used tools for picking high-level fruits are ladders and long poles. When picking high-level fruits with a ladder, you have to climb up and down the ladder frequently. Once you change the picking position, you need to move and lift the ladder, which affects the efficiency of fruit picking. Although the efficiency of picking high-level fruits with a long pole is high, the fruit knocked down by the long pole has not been selected, and the fruit tree and the fruit will be damaged during the falling process. For the problems referred to above, people begin to develop and use fruit picking device. [0003] Common picking methods in fruit picking devices are: (1) sucking, first use the suction nozzle to suck the fruit firmly, and then forcefully pull the fruit off the fruit ...

AI Technical Summary

Problems solved by technology

Although the method of receiving fallen fruit by gravity is more efficient, the damage rate of the fruit is also high and the degree of automation is low, so it is rarely used in the fruit picking device; the picking and placing mode affects the efficiency and is difficult due to the frequent clamping and moving of the fruit. Control is rarely used in fruit picking devices; pipeline transmission is the most widely used method today, but special transmission channels and transmission mechanisms must be designed, which will not only increase the lifting weight, but also complicate the lifting structure

, the common lifting methods are: (1) lifting table, large in size, large in lifting load and poor in flexibility; (2) telescopic rod, small in size, light in lifting load and flexible; (3) mechanical arm, moderate in size and large in lifting load , Flexible but difficult to control. In the current fruit picking devices, robotic arms are mostly used, but the load capacity, flexibility and controllability must be further coordinated

[0004] Transportation is the biggest obstacle affecting the application of fruit picking devices. Since orchards are mostly sloping land and the road traffic conditions are poor, it is difficult to use a slightly larger carrier vehicle effectively; the second is power supply. Supply is difficult; and the spacing and height of fruit trees also limit the investment of large-scale picking equipment
