Description

Technical Field

[0001] The utility model relates to the technical field of solution sampling devices, in particular to a sampling device for detecting the components of a solution. Background Art

[0002] Soil solution detection refers to the analysis and determination of the liquid phase part in soil. The soil solution contains a variety of inorganic and organic compounds, and their composition and properties are often affected by soil parent material, climate, terrain and organisms, and in turn affect soil formation, development and plant growth. The substances in the soil solution are the basis for the migration and transportation of soil substances and an important source for plant roots to obtain nutrients. Some can reduce the surface tension of the solution to varying degrees and produce positive adsorption, while others may increase the surface tension of the solution and produce negative adsorption.

[0003] When the existing soil solution sampling device is used, it is directly inserted into the soil to extract the solution sample, resulting in a large amount of soil in the solution sample after sampling, leading to a low purity of the solution. It is very difficult for the soil solution sampling device to effectively separate soil particles and soil solution, causing soil particles to mix into the solution and affecting the results of subsequent chemical analysis and experiments. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a sampling device for detecting the components of a solution. Under the action of air pressure, the soil solution enters the inside of the cylinder through the cylinder body, the piston and the suction cylinder. A filter cylinder is installed inside the suction cylinder, and the cylinder body realizes the effective separation of soil particles and soil solution through the filter cylinder inside the suction cylinder.

[0005] In order to achieve the above purpose, the utility model adopts the following technical scheme:

[0006] A sampling device for detecting the components of a solution, including a cylinder body, a sampling bottle is threadedly installed on the cylinder body, a piston is arranged inside the cylinder body, a suction cylinder is threadedly installed at the bottom end of the cylinder body, a conical head is arranged on the suction cylinder, a filter cylinder and a cleaning mechanism are installed inside the suction cylinder, the cleaning mechanism includes a brush, the brush is slidably matched inside the suction cylinder, and the brush is attached to the side wall of the filter cylinder.

[0007] Preferably, a T-shaped rod is installed on the piston, and a sealing cover penetrates through the T-shaped rod.

[0008] Preferably, the sealing cover is threadedly matched with the top end of the cylinder body.

[0009] Preferably, a conveying pipe is connected to one side of the cylinder body, and the sampling bottle is installed on the conveying pipe.

[0010] Preferably, the inside of the suction cylinder is hollow, the top end of the suction cylinder is threadedly matched with a T-shaped cylinder, and a chute and an opening are formed on the suction cylinder.

[0011] Preferably, a slider is fixed at the top of the brush, and the slider is slidably fitted inside the chute.

[0012] The utility model has the following beneficial effects:

[0013] 1. A filter cartridge is installed inside the suction cylinder at the bottom end of the cylinder body. Soil particles and soil solution in the soil can be separated and blocked by the filter cartridge inside the suction cylinder. The T-shaped rod drives the piston to move inside the cylinder body, so that a negative pressure is formed inside the cylinder body. Under the action of air pressure, the soil solution enters the cylinder body through the suction cylinder. The soil solution is transported to the sampling bottle through the delivery pipe, realizing the sampling of the soil solution, avoiding a large amount of soil in the solution sample after sampling, further improving the purity of the solution, and ensuring the accuracy of the detection and measurement results of the solution components.

[0014] 2. A filter cartridge and a cleaning mechanism are installed inside the suction cylinder. The brush is attached to the side wall of the filter cartridge, and the slider is slidably fitted inside the chute, preventing the filter cartridge inside the suction cylinder from being blocked. The cylinder body realizes the effective separation of soil particles and soil solution through the filter cartridge inside the suction cylinder, avoiding soil particles directly entering the cylinder body, ensuring the sampling operation of the soil solution, and facilitating the secondary use of the sampling device by the user.

A suction cylinder 3 is installed on the bottom end of the cylinder body 1 in a threaded manner. A conical head 4 is arranged on the suction cylinder 3. The cylinder body 1 enables the suction cylinder 3 to suck the soil solution into the inside of the cylinder body 1 under the action of air pressure through the sealing cover 101, the T-shaped rod 102 and the piston 103. A sampling bottle 2 is installed on the cylinder body 1 in a threaded manner. A conveying pipe 104 is connected to one side of the cylinder body 1.

[0022] A filter cylinder 5 and a cleaning mechanism 6 are installed inside the suction cylinder 3. The inside of the suction cylinder 3 is hollow. The top end of the suction cylinder 3 is in threaded fit with a T-shaped cylinder 301. A chute 302 and an opening 303 are formed on the suction cylinder 3. The cleaning mechanism 6 includes a brush 601. The brush 601 is slidably fitted inside the suction cylinder 3. The brush 601 is in contact with the side wall of the filter cylinder 5. A slider 602 is fixed to the top end of the brush 601. The slider 602 is slidably fitted inside the chute 302, preventing the filter cylinder 5 inside the suction cylinder 3 from being blocked. The cylinder body 1 realizes the effective separation of soil particles and soil solution through the filter cylinder 5 inside the suction cylinder 3, avoiding soil particles directly entering the inside of the cylinder body 1 and mixing into the solution collected by the sampling bottle 2 on the cylinder body 1, ensuring the sampling operation of the soil solution.

[0023] When using the sampling device to detect the components of the solution in the soil, place the cylinder body 1 in the soil. The cylinder body 1 moves to the specified depth in the soil through the conical head 4 at the bottom end of the suction cylinder 3. Pull the T-shaped rod 102 on the sealing cover 101, which can drive the piston 103 to move inside the cylinder body 1, causing a negative pressure inside the cylinder body 1. The soil particles and soil solution in the soil can be separated and blocked by the filter cylinder 5 inside the suction cylinder 3. The soil solution enters the inside of the cylinder body 1 through the suction cylinder 3 under the action of air pressure. The soil solution is transported to the inside of the sampling bottle 2 through the conveying pipe 104 to realize the sampling of the soil solution. After sampling, slide the brush 601 of the cleaning mechanism 6 inside the suction cylinder 3 through the chute 302, so that the brush 601 can clean the filter cylinder 5, avoiding the filter cylinder 5 from being blocked due to the influence of soil particles.
