Problems solved by technology

[0003] Scientific sampling is a prerequisite for carrying out environmental risk monitoring of pesticides. If there are obvious defects in sampling methods and tools, the samples will inevitably be separated from the real environmental background, and there will be problems such as large fluctuations in residual values ​​and low reliability of prediction results, which will further affect risk assessment. bring difficulties
For example, in the field of pesticide environmental risk monitoring and sampling in paddy fields, the current method of sampling field water and soil separately has virtually broken the internal relationship between the two, and there is a lack of field water depth parameters and inconsistent overlap of samples in vertical space As a result, the test results of sample residues can only be used as a general reference, and cannot meet the rigid requirements of environmental prediction calculations and risk prevention
Moreover, various tools such as water bottles, soil drills, and grabs are used to sample field water and soil, but there are still shortcomings such as a large number of tools to carry and use, cumbersome operating procedures, heavy workload for operators, and inaccurate sample depth.

Embodiment 1

[0016] A paddy field environmental monitoring sampler, comprising a scale conduit 1, a tube base 2, a sealing piston 7, a handle 4, and a rack linkage device, the scale conduit is connected to the tube base 2, the tube base 2 is connected to the handle 4, and the There is a sealing piston 7 inside the scale guide, and the seal piston moves in the scale guide through a rack linkage. The rack linkage device includes an adjustable wrench 3, a rack 8, a paddle return spring 10, and a movable paddle 11. The middle part of the tube base 2 has a tube rack hole 19, and the tube base 2 is connected to the handle by screws. 4. The handle 4 is made of iron sheet tailoring and bending. The left end of the handle 4 has a paddle return spring 10. The right end of the paddle return spring 10 is connected to the movable paddle 11. The movable paddle 11 The middle part has a paddle rack hole 18, the bottom of the movable paddle 11 has a paddle tongue 22, the cross section of the adjustable wre...

Embodiment 2

[0018] In the paddy field environmental monitoring sampler described in Example 1, the scale conduit 1 is made of a transparent pipe, and the scale conduit has centimeter scales, which can extract soil columns in sections or at fixed depths. The right side of the scale conduit 1 has 1 or 2 air valves 9, and the right end of the scale conduit is connected with the internal thread of the pipe seat with external threads, and the distance between the air valve 9 and the pipe seat 2 is greater than the thickness of the sealing piston 7, so The scale conduit 1 has a sealing piston 7 inside, the sealing piston 7 is connected to the left end of the rack 8 , and the right end of the rack 8 is connected to the handle 14 .

Embodiment 3

[0020] A paddy field environmental monitoring sampling method, comprising the following steps:

[0021]1. Open the valve: press the stopper, pull out the handle of the rack, move the piston back to the top of the duct valve, release the stopper to automatically return to its position under the action of the return spring of the stopper, and withstand the rack;

[0022] 2. Insert the sampling conduit into the paddy field and exhaust: hold the conduit firmly with one hand and hold the handle with the other hand, gently spin the sampler conduit perpendicular to the field surface into the plow layer soil to reach the bottom of the plow, so that the excess gas in the conduit is discharged through the valve;

[0023] 3. Close the air valve to form a closed space: Pull the adjustable wrench with your fingers to drive the movable paddle to catch the rack and move forward one to several grids. After the movable wrench is released, the movable paddle returns to the initial state under th...

Description

technical field [0001] The invention relates to the field of farmland environment monitoring and sampling, in particular to a paddy field environment monitoring sampler and a sampling method. Background technique [0002] Pesticide risk monitoring is a complex system engineering. For various risks, it is necessary to prevent them in advance, and to make necessary improvements to the risk management methods during and after the events, and to repeat and cycle improvements. In recent years, out of the need to protect the safety of agricultural production, the quality and safety of agricultural products, the ecological safety of the environment, and the health and safety of humans and animals, my country has begun to strengthen the risk monitoring of pesticide use. Farmland environmental risk monitoring is an important part of it. However, due to work Late start, poor foundation, some technical methods are still incomplete and need to be improved urgently. [0003] Scientific ...
