Liquid nitrogen flower thinning and fruit thinning device

Abstract

The invention discloses a liquid nitrogen flower thinning and fruit thinning device, which comprises a liquid nitrogen storage tank. The upper surface of the liquid nitrogen storage tank is respectively provided with a liquid nitrogen injection pipe and a piston device, and the side walls of the liquid nitrogen storage tank are respectively provided with a liquid nitrogen spraying device and a rodlength adjusting device. A control device is further arranged on the rod length adjusting device, and universal wheels are arranged at the bottom of the liquid nitrogen storage tank. The liquid nitrogen flower thinning and fruit thinning device has the advantages of fully utilizing the principle of liquid nitrogen gasification and refrigeration to spray liquid nitrogen onto flower buds or fruitsthat need to be killed to freeze them to death, thusachieving the goal of fast flower thinning and fruit thinning.

Description

technical field [0001] The invention belongs to the technical field of agricultural machinery and equipment, and in particular relates to a liquid nitrogen flower and fruit thinning device. Background technique [0002] The mechanization development level of my fruit orchards is relatively backward, and the development of each production area is very uneven. The mechanical operations such as plowing, pruning, plant protection, fertilization and picking in the production process are more difficult. Most production areas even only use some simple machines. Do manual work. Flower thinning and fruit thinning is one of the important measures to improve fruit quality in fruit production. The main purpose is to improve fruit quality by preventing excessive fruiting, reduce nutrient consumption, improve the quality of flower bud differentiation, and reduce or avoid the phenomenon of large and small years. [0003] There are three main methods of flower thinning and fruit thinning: ...

AI Technical Summary

Problems solved by technology

[0003] There are three main methods of flower thinning and fruit thinning: artificial, mechanical and chemical methods; the manual method is simple, but time-consuming and labor-intensive; the mechanical method has been in the experimental state, and the existing flower and fruit thinning machines are hand-held machines. The efficiency is limited; the chemical method has high efficiency and low cost, but it is easy to cause fruit pesticide residues and ecological environment pollution. From the perspective of food and environmental pollution, and from the perspective of food and environmental safety, the prospect of chemical flower thinning is not optimistic

Therefore, the labor dependence of flower thinning and fruit thinning operations still exists
