Vegetable liquid spray pollination spray head with adjustable spray width

Abstract

The invention discloses a vegetable liquid spray pollination spray head with adjustable spray width, and belongs to the technical field of agricultural machinery. The vegetable liquid spray pollination spray head structurally comprises a positioning center shaft, a telescopic arm, a support joint rod, spray nozzles, a hydraulic cylinder, a telescopic joint, an annular pin, a sliding connecting column, a fixed connecting column, a telescopic hose, a pin and a pipeline which are connected with one another. The structure is novel, and the cylinder wall of the hydraulic cylinder drives the slidingconnecting column to slide along the positioning center shaft to drive the supporting joint to move, fine adjustment of the included angle between the telescopic arm and the positioning center shaftis achieved, and therefore the relative position distance between the spray nozzles is changed. A pollen solution enters from a feeding port and enters electrostatic nozzles through the positioning center shaft, the telescopic hose and an internal channel of the telescopic arm for pollination. When pollination is conducted on other objects, positions are adjusted again according to positions and sizes of flowers, and the operation is repeated. Compared with a traditional pollination structure, the pollination spray head has the advantages that the adaptability is high, the operation efficiencyis high, pollination can be uniform through an electrostatic spraying pollination mode, the pollen deposition amount is increased, and pollen grain waste is avoided.

Description

technical field [0001] The invention belongs to the technical field of agricultural machinery and relates to a vegetable pollination mechanism, in particular to a vegetable liquid spray pollination nozzle with adjustable spray width. Background technique [0002] The flowering period of vegetables is short, the traditional manual pollination method is time-consuming and laborious, the work efficiency is low, and it is difficult to complete the pollination within the specified time, so the promotion and use of mechanical pollination methods is necessary. [0003] The liquid spray pollination technology uses a sprayer to atomize and spray a special pollen suspension to the stamen stigma for pollination. However, the current spray pollination method has low precision and the spraying is blind. Large-scale spraying methods are mostly used to make pollen deposits on the stamens Insufficient pollination will significantly affect the success rate of vegetable pollination, seed sett...

[0003] The liquid spray pollination technology uses a sprayer to atomize and spray a special pollen suspension to the stamen stigma for pollination. However, the current spray pollination method has low precision and the spraying is blind. Large-scale spraying methods are mostly used to make pollen deposits on the stamens Insufficient pollination will significantly affect the success rate of vegetable pollination, seed setting rate, internal and external quality, endogenous hormone content and seed germination ability, etc.

[0004] Chinese patent application number 201620195084.3 utility model patent proposes a spray-type kiwifruit powder end actuator, including a spray mechanism, a distance adjustment mechanism, a fine-tuning mechanism, a sensing system and a control system. The distance adjustment mechanism is driven by a vertical screw. Two support rods drive the spraying mechanism to move up and down to achieve the optimal distance for pollination. The fine-tuning mechanism distributes three thin cylinders corresponding to the three nozzles to realize real-time fine-tuning of each nozzle. However, the spray-type kiwifruit powder end effector It can only adjust the longitudinal distance from flowers, and cannot adapt to the pollination of flowers of different sizes, meeting the high adaptability requirements of agricultural machinery
