Embodiment Construction

[0023] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0024] Such as figure 1 , figure 2 As shown, the present invention includes a drug delivery device, a variable spray control device, a variable spray detection device, a drug application device and a machine vision target device; wherein:

[0025] 1) Drug delivery device: including a medicine box 1, a first filter 2, a spray pump 3, an accumulator 5, an exhaust valve 6, a first manual control valve 7 and a second filter 2 connected sequentially through the main pipeline , and the safety valve 4 provided in the loop between the spray pump 3 and the medicine box 1. The medicine box 1 is used to hold the medicinal liquid, and the medicinal liquid needs to be stirred and mixed before the spray test machine works. The first filter 2 is used to filter the impurities in the liquid medicine and protect the spray pump 3 and the main pipeline. The medicine s...

Abstract

The invention discloses a toward-target variable spray tester. The toward-target variable spray tester comprises a medicine feeding device, a variable spray controller, a variable spray detector, a medicine applying device and a machine vision toward-target device. The toward-target variable spray is realized according to the existence of a medicine spraying target, the size of a target crop area, and the change of the running speed of a spraying vehicle, so that the precision spraying of the crop can be realized, the effectiveness of the medicine liquid can be improved, and the waster of the medicine liquid and the pollution of the environment can be reduced. According to the tester, the spraying can be automatically completed, the corresponding control and adjustment can be carried out according to the real-time data, the spray tester ensures a spraying scheme and transmits to the spraying scheme to a singlechip according to an image acquired in the field and a preset image processing algorithm, the singlechip controls an electric proportioning valve to control the flow, an electromagnetic valve to control the length of the turning-off/on time, the toward-target variable spray is carried out, and the toward-target variable spray tester is multifunctional and convenient to operate. Meanwhile, the variable spray can be manually and automatically changed, so that the toward-target variable spray tester is convenient to select and use in the spraying field.

Description

technical field [0001] The invention relates to a spray machine, in particular to a target variable spray test machine applied to the spraying operation of pesticides. Background technique [0002] At present, ordinary sprayers used in pesticide spraying operations are mainly suitable for uniform operations over the entire area, and their pest control effects are better. However, in the process of operation, due to the lack of analysis of the presence or absence of the application target and the size of the target area, problems such as low effective utilization of pesticides, excessive pesticide residues in agricultural products, environmental pollution, crop injury, and operator poisoning have been caused. In order to reduce the amount of pesticide application and improve the effective utilization rate of pesticides, the application technology of target variables has become the focus of research in recent years.
