Problems solved by technology

[0003] At present, there are mainly two detection methods based on water-sensitive test paper. One is the method of manual counting. Under a magnifying glass, direct visual estimation is performed. This method wastes a lot of human resources and has large detection errors and low efficiency.
The other is the method of laying water-sensitive test paper, that is, lay water-sensitive test paper in the target area, and evaluate the spraying effect by calculating the proportion of the spray droplets scattered on the test paper. This method needs to use a scanner to collect images Finally, using computer software to analyze the spraying effect, it is impossible to achieve rapid detection and data acquisition, and at the same time, the detection results will be deviated due to fog droplet blooming

Embodiment 1

[0045] On the basis of the above structure, in this embodiment, a gear 6 and a rack 7 are installed in the outer box 1 , the rack 7 is arranged vertically, and the upper end of the rack 7 is connected to the image capturing device 3 ; the gear 6 can be positioned and rotated horizontally It is on one side of the rack 7 and meshes with the rack 7 ; the gear 6 rotates and drives the image acquisition device 3 to move up and down through the rack 7 . When the position of the image capturing device 3 in the vertical direction needs to be adjusted, the gear 6 is rotated in a manner that those skilled in the art can think of, and the gear 6 uses the meshing force between the gear 6 and the rack 7 to drive the rack 7 to move up and down, Therefore, the image capturing device 3 is driven to move up and down, thereby adjusting the position of the image capturing device 3 in the vertical direction, the structure is simple, and the adjustment is convenient and quick.

Embodiment 2

[0047] On the basis of the first embodiment, in this embodiment, the upper end of the rack 7 is fixedly installed with a carrier box 8 for carrying the image capture device 3, and the carrier box 8 is fixed to the upper end of the rack 7 by welding or bolting; The image capturing device 3 is fixed in the carrying box 8 by bolts. Here, the image capture device 3 is carried by the carrier box 8 , which is convenient for installation and can increase the stability of the image capture device 3 in the moving process.

Embodiment 3

[0049] On the basis of the first embodiment, in this embodiment, a gear shaft 9 is installed in the outer case 1 to be positioned and rotated horizontally, and the gear 6 is coaxially fixed and sleeved on the gear shaft by means that those skilled in the art can think of. 9, a bar-shaped opening 10 is horizontally provided on one side of the outer case 1; During adjustment, the gear shaft 9 is rotated to drive the gear 6 to rotate, so as to use the meshing force between the gear 6 and the rack 7 to drive the rack 7 to move up and down, thereby driving the image acquisition device. 3 Move up and down to adjust the position of the image capture device 3 in the vertical direction; in addition, move the gear shaft 9 horizontally to drive the gear 6, the rack 7 and the image capture device 3 to move in the horizontal direction to adjust the image capture device 3 The position in the horizontal direction is suitable for water-sensitive test strips of different sizes and has a wide r...

Abstract

The invention relates to rapid detection equipment for water-sensitive test paper. The equipment comprises an outer box, a processor, an image acquisition device and an illumination device, the imageacquisition device and the illumination device are in communication connection with the processor, and the top of the outer box is open and a transparent plate used for containing to-be-detected water-sensitive test paper is installed horizontally. The image acquisition device is horizontally and movably mounted in the outer box, can move up and down and is used for acquiring an image of the water-sensitive test paper on the transparent plate; the illumination device and the processor are both fixedly installed in the outer box, and the processor receives images collected by the image acquisition device and processes and analyzes the images. The invention also provides a rapid detection method of water-sensitive test paper. The equipment and the device have the beneficial effects that accurate data can be immediately obtained after spraying, the detection cost is reduced, the workload is reduced, the equipment is flexible, the precision and efficiency of test paper detection after spraying can be greatly improved, and portable and efficient detection operation is realized.

Description

technical field [0001] The invention relates to the technical field of pesticide spraying effect detection, in particular to a water-sensitive test paper rapid detection device and a detection method. Background technique [0002] Fruit tree spraying is a regular work in the process of orchard plant protection. Although this operation can effectively improve the quality of fruit production, the residue of pesticides in the soil will lead to the decline of soil fertility and even hardening. In order to solve the serious damage caused by pesticides to the orchard environment and achieve the goal of precise spraying in the orchard, the sprayer will use water-sensitive test paper to measure the coverage of pesticide droplets during the research and development process. [0003] At present, there are two main detection methods based on water-sensitive test strips. One is the manual counting method. Under the magnifying glass, direct visual estimation is performed. This method was...
