Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of water quality detection equipment and method, and particularly relates to an automatic dyeing detection equipment and method for agricultural water quality. BACKGROUND

[0002] Water is the source of life, and human beings cannot live without water in life and production activities. The quality of drinking water is closely related to human health. With the development of social economy, scientific progress and the improvement of people's living standards, people's requirements for the quality of drinking water are increasing, and the drinking water quality standards are also continuously developed and improved. Because the formulation of drinking water quality standards is related to many factors such as people's living habits, culture, economic conditions, scientific and technological development level, water resources and water quality status, there are differences in the requirements for drinking water quality not only between countries but also between different regions of the same country.

[0003] The principle of water quality dyeing detection is mainly to measure the color intensity of water quality by measuring the absorption or reflection of light, so as to judge the quality of water. A specific wavelength of light emitted by a light source is used to irradiate the water body, and the colored substances in the water body will absorb part of the light, resulting in a decrease in light intensity. The photoelectric converter converts the light intensity into an electrical signal, and the signal processor calculates the color value of the water body according to the change of the electrical signal and displays it through the display.

[0004] In the process of water quality dyeing detection, if there are a large number of stones or obstructions on the inner wall and bottom of the water body and a large amount of garbage floating on the water body, the emitted light cannot pass through, thereby affecting the normal water body detection work. Therefore, it is often necessary to remove the impurities in the water tank before detection, but the above process is inconvenient to operate, reduces the work efficiency, and the water body in the water tank also has an odor, which is not conducive to the normal work of personnel in such an environment, and the application of the device is also reduced.

Based on the embodiments in the present application, all other embodiments obtained by a person of ordinary skill in the art without creative effort belong to the scope of protection of the present application.

[0043] As shown in Figure 1 and Figure 2 , the automatic dyeing detection equipment for agricultural water quality comprises:

[0044] a water storage tank 1;

[0045] a first cleaning treatment mechanism 2, the first cleaning treatment mechanism 2 comprises a driving motor 3 arranged on the water storage tank 1, an output shaft of the driving motor 3 extends to a central rotating tooth 5 through a first bevel gear 4, a triangular plate 6 connected through the output shaft of the driving motor 3 is arranged between the central rotating tooth 5 and the first bevel gear 4, gear plates 7 reversely moving in engagement are arranged on the outer wall of the central rotating tooth 5 at both ends, one end of the gear plates 7 is connected to a push plate 8, and a storage box 9 with a notch is arranged at both ends of the water storage tank 1;

[0046] a second cleaning treatment mechanism 10, the second cleaning treatment mechanism 10 comprises a second bevel gear 11 in engagement with the first bevel gear 4, one end of the second bevel gear 11 is fixed on a movable shaft 12, the movable shaft 12 and a driving wheel 13 on the side wall of the water storage tank 1 are drivingly connected through a first conveying belt 14, the driving wheel 13 and a driven wheel 15 are drivingly connected through a second conveying belt 16, a scraper 17 is integrally connected on the second conveying belt 16, the scraper 17 is arranged in a direction of movement and is arranged on the water storage tank 1, an opening is arranged between the scraper 17 and a collecting cylinder 18, and the opening and the collecting cylinder 18 are connected through an inclined plate 19.

[0047] As shown in Figure 3 , Figure 4 , Figure 5 and Figure 6 , the first cleaning treatment mechanism 2 cooperates with the second cleaning treatment mechanism 10 to clean the stones at the bottom of the inner wall of the water storage tank 1 and the floating garbage, so as to facilitate normal fiber emission of the light source, and in extension, the triangular plate 6 above the push plate 8 is arranged, on one hand, the large-particle impurities such as stones can be guided to both sides of the push plate 8, so as to facilitate subsequent cleaning work, and on the other hand, the triangular plate 6 provides a moving space for the central rotating tooth 5 and the gear plates 7, so as to ensure normal movement of the transmission member.

[0048] The second cleaning treatment mechanism 10 can drive the rotation of the first bevel gear 4 under the action of the driving motor 3, the second bevel gear 11 can reverse the transmission force, and can drive the rotation of the second conveying belt 16. During the rotation of the second conveying belt 16, the floating garbage can be pushed into the collecting cylinder 18 through the cleaning plate 19, so as to directly further the compression treatment work.

[0049] The first cleaning treatment mechanism 2 is arranged. After the driving motor 3 is started, the central gear 5 can drive the gear plates 7 at both ends to move reversely, so as to clean the stones and large-particle impurities deposited at the bottom of the water storage tank 1 into the storage box 9.

During the movement of the pressing plate 24, the guide column 25 can effectively prevent the transmission member from deviating during movement. The guide column 25 and the reciprocating screw 22 are arranged in parallel at the same height, so that the pressing plate 24 can maintain corresponding stability during movement.

[0054] The pressing mechanism and the material guiding assembly 26 are arranged, when the driving motor 3 is started, the third conveying belt 21 can drive the rotation of the reciprocating lead screw 22, under the action of the screw transmission, the pressing plate 24 can move up and down and press the garbage, so that the space inside the collecting cylinder 18 is effectively utilized, in addition, since the garbage is continuously conveyed into the collecting cylinder 18, in order to ensure that the garbage can be effectively conveyed into the collecting cylinder 18, the movable material guiding opening is arranged on the pressing plate 24, the compression spring 29 and the limiting plate 30 are matched, the baffle 28 can only rotate and move downward and open the material guiding opening, and the compression spring 29 can help the baffle 28 reset, so that the pressing mechanism can stably press the garbage, and the garbage can be continuously conveyed, and the working efficiency is improved.
