Lifting apparatus and safflower picking manipulator

Abstract

The invention provides a lifting apparatus and a safflower picking manipulator, and relates to the technical field of safflower picking. The lifting apparatus provided by the invention comprises a support shell, a first driving mechanism, and a position-limiting claw movably connected with the support shell, wherein the support shell and the position-limiting claw are connected with the first driving mechanism, and the first driving mechanism is used to drive the position-limiting claw to move relative to the support shell, so that the position-limiting claw forms a channel for grabbing a flower stem, and a lifting cavity for lifting filaments. The lifting apparatus provided by the invention can directly grasp the flower stem and lift the filaments through the lifting cavity, and effectively limits a position of a fruit ball. Even in relatively severe weather, such as windy weather, the position-limiting claw can ensure that the flower stem is stable, the lifting cavity formed by the position-limiting claw can play a certain position-limiting role in the filaments to avoid scattered distribution of the filaments, and thereby the occurrence of incomplete filament picking is effectively reduced.

Description

technical field [0001] The invention relates to the technical field of safflower picking, in particular to a lifting device and a safflower picking manipulator. Background technique [0002] Since the beginning of the 21st century, safflower has been a commercial crop. With the vigorous development of the domestic industry, the planting area of ​​safflower has grown rapidly. It is planted in Xinjiang, Tibet, Henan, Hunan, Sichuan and other places in my country. It generally takes 15-20 days for safflower to bloom from the beginning to the end of flowering. With the number of days after safflower blooming, the shape of safflower will gradually change. Therefore, safflower should not be picked too early or too late, and must be picked in good time. The fruit balls on a single safflower plant are spatially distributed relative to the plant stem, and there are about 20 fruit balls per plant. The fruit balls are of different heights and open at different times, making it difficul...

Problems solved by technology

However, in the air-suction collection equipment, there is friction between the airflow itself and the inner wall of the pipeline, so that the energy carried by the airflow itself gradually decreases in the flow direction, which will cause the pressure of the airflow in the separation device to decrease, and finally Causes the fan to waste a lot of power, and the high-pressure airflow will damage the safflower filaments

In the roller collection equipment: there will be a lot of vibration during work, the bearing seat will be subject to intermittent loads, and at the same time, the bearing will generate a lot of heat when carrying high-speed motion, which will accelerate the deformation of the shell, and the size of each safflower flower varies. Poor applicability and serious damage to the shape of safflower, and the traditional mechanical cutting collection equipment cannot stably limit the position of the fruit ball, resulting in incomplete filament picking when picking filaments
