Portable chemical flower thinning device for orchard

Abstract

The invention relates to a portable chemical flower thinning device for an orchard. The device mainly comprises a portable bearing unit, a spray unit, a rod length adjustment unit and a control unit. The spray unit comprises a chemical case, a variable pump, a chemical delivery tube and a nozzle and is used for spraying flower thinning chemicals to fruit trees. The rod length adjustment unit comprises a handle, a motor, a coupler, telescopic rods, a screw, a nut and an adjustment nut and is used for adjusting the length of a spray rod and facilitating flower thinning and fruit thinning of fruit trees of different heights. The control unit comprises a power supply, a controller, a variable pump control switch and a motor control switch and is used for controlling the spray amount and the length of the spray rod. According to the portable chemical flower thinning device, a screw nut mechanism is driven by the motor to adjust the length of the spray rod automatically, multi-stage variable spray can be achieved through the variable pump, the smooth and easy completion of spraying can be achieved through a portable back pack, and by means of the chemical flower thinning method, the labor productivity is improved, and labor costs are saved.

Description

[0001] 1. Technical Field: The present invention relates to a flower thinning and fruit thinning machine for orchards, in particular to a portable chemical flower thinning equipment for orchards, which belongs to the field of agricultural machinery. 2. Background technology: [0002] Under normal growth conditions, fruit trees generally bloom excessively, causing the tree to consume too much nutrients. If it is allowed to grow, it will cause big and small fruit. Flower thinning is to preserve fruit. Fruit thinning can overcome the phenomenon of large and small year-round fruit, and timely and appropriate flower thinning can promote the healthy growth of fruit trees and increase the quality rate of fruit. Therefore, flower thinning and fruit thinning are very important in the growth process of fruit trees. Management links. [0003] There are three main methods for thinning flowers and fruits: manual, mechanical and chemical. The manual methods are simple, but they are time-consumin...

AI Technical Summary

Problems solved by technology

[0003] The main methods of flower thinning and fruit thinning are manual, mechanical and chemical. The manual method is simple, but labor-intensive and time-consuming, and the operation efficiency is low; the mechanical method has been in the experimental state, and there is no relatively mature and effective flower and fruit thinning machine for actual operation; The chemical method has high efficiency and low cost. In developed countries, the chemical method of flower thinning and fruit thinning has almost replaced manual labor and has become the main method of flower thinning. Therefore, chemical flower thinning has developed rapidly and is widely welcomed by fruit farmers. However, equipment for chemical flower thinning It is still relatively backward, and cannot meet the current flower and fruit thinning operations of large orchards
