A control method of a lifting arm telescopic jujube harvesting device

Abstract

The invention relates to a control method of an arm-lifting retractable-type jujube picking device. The arm-lifting retractable-type jujube picking device is adopted for controlling an arm-lifting retractable-type jujube picking process and arranged at the upper portion of a quadrangular arm-lifting retractable mechanism through a jujube beating mechanism baseplate; compared with a traditional retractable rod form, the method has the advantage that when a jujube beating operation mechanism moves up and down, an operator only needs to hold a handle rod for adjustment instead of lifting a retractable rod to carry out operation so that strength can always be saved easily when the jujube beating operation mechanism moves up and down or front and back. Since the retractable mechanism adopts a quadrangular structure and the portion between a long rod and a vertical rod of a chassis is adjusted through a ratchet wheel control assembly, the angle of the long rod relative to the vertical rod ofthe chassis is kept unchanged due to the ratchet wheel characteristics of bidirectional ratchet wheel sliding blocks; the operator does not need to hold the handle rod to maintain the angle of the long rod relative to the vertical rod of the chassis, so that more strength is saved, operation is more efficient, jujube picking operation can be conducted for a long time, and the applicability is high.

Description

technical field [0001] The invention relates to the technical field of mechanical picking control, in particular to a control method of a telescopic jujube picking device with lifting arms. Background technique [0002] Although the output and types of jujubes in my country are relatively large, mechanization has not been implemented for jujube picking, and there are still deficiencies in many places. The efficiency of large-scale machinery is relatively low, and the types of small-scale equipment are also less and not complete, mainly semi-automatic It is dominated by advanced machinery, such as movable fruit picking ladders and retractable high pickers. These types of machinery have improved the quality of fruit picking to a certain extent, but jujubes are distributed in various parts of fruit trees, and traditional picking methods are mainly manual. Sticks are used to beat large-scale mechanized equipment, which is not only costly, but also has strict requirements on the pl...

[0003] The invention patent with the patent number CN201320085511.9 discloses an economical and changeable jujube picking pole. When the chain link bar is disassembled, when the picker picks the jujube, it takes a lot of strength to lift the jujube picking pole, and when the continuous working time is long, the picker is prone to fatigue, resulting in low efficiency of jujube picking, and it is impossible to carry out labor-saving and efficient work for a long time. Jujube picking; the invention patent with the patent number of CN201520182378.8 discloses an economical and changeable jujube picking pole, in which the engine, cab and steering device are arranged on the fuselage, and the fuselage is installed on the walking parts. The fruit container is located at the lower part of the front end of the fuselage, the sweeping plate is located at the front end of the fruit suction device, the horizontal conveying device is installed at the lower end of the fuselage, the vertical conveying device is installed at the tail of the fuselage, and the fork-shaped disc follower fruit receiving mechanism is installed on the The lower end of the fuselage, and the fork-shaped disc follow-up fruit receiving mechanism corresponds to the horizontal conveying device. The fruit collection box is installed at the rear of the fuselage, and the main fruit collection box corresponds to the output end of the vertical conveying device; The red dates that fell on the ground are collected into the random fruit collection box of the harvester, but the self-propelled fully hydraulic red date harvester is huge in size, complex in equipment structure, high in cost, and has high requirements on the layout of the orchard, requiring the orchard planting distance It is larger than the self-propelled full hydraulic jujube harvester, so it is not suitable for small orchards with high fruit tree planting density
