Description

Technical Field

[0001] The invention relates to the technical field of soil sampling, in particular to a sampling device for soil environment monitoring. Background Art

[0002] Soil sampling refers to the process of obtaining representative soil samples from a specific soil area. This is a very important basic work in many fields such as soil science research, environmental monitoring, and agricultural production. Its purpose is to infer the properties, composition, fertility, pollution level, and other characteristics of a larger area of ​​soil by analyzing a small amount of soil samples.

[0003] A Chinese invention patent with publication number CN118500800A discloses a greening soil sampling device for municipal gardens, including: a fixed plate, and also including: a lifting component, the lifting component is connected to the fixed plate, and the output end of the lifting component is connected to the lifting plate; a rotating component, the rotating component is connected to the lifting plate, and the output end of the rotating component is connected to the rotating plate, and the rotating plate is rotatably connected to the bottom of the lifting plate through a bracket. The present invention is provided with a lifting component, a rotating component, a sampling barrel and an auxiliary mechanism, and the lifting component and the rotating component drive the sampling barrel to rotate while moving downward, so as to cut and sample the frozen soil, and the sampling barrel is ventilated and cooled in real time by the auxiliary mechanism, so that the heat generated by friction can be discharged in time during the sampling process, thereby effectively improving the sample quality and ensuring the accuracy of the sample detection.

[0004] In addition, when sampling on harder soil, the soil sample will be squeezed to a certain extent during the rotation process, thereby destroying the original structure of the soil sample. In addition, it is inevitable that some stones will be mixed in the soil. If the stones are not cleaned, the soil content in the soil sample will be reduced, and the resistance of the soil entering the sampling tube will increase, thereby affecting the sampling rate. When there is more and more soil in the sampling tube, the gas inside the sampling tube will become larger. If the pressure is not relieved, the looseness of the soil inside the sampling tube will increase, and the soil at different depths will be mixed with each other intermittently, thereby affecting the accuracy of the soil sample test results. Therefore, the greening soil sampling equipment for municipal gardens disclosed in Chinese invention patent CN118500800A cannot filter the stones in the soil and cannot prevent the soil sample from being mixed after loosening, resulting in inaccurate test results.

The two ends of the spring 411 are respectively fixedly connected to the limit plate 42 and the piston plate 410. The filtering holes 48 set in the sampling mechanism 4 can filter the stones inside the soil. At the same time, under the action of the piston plate 410 and the spring 411, the soil is prevented from entering the interior of the sampling tube, which causes the air pressure on the inner wall of the sampling tube to increase.

[0039] The following is the working process and principle of the above embodiment:

[0040] The initial state is as follows: the driving impact rod 25 is in an unextended state, the impact plate 26 is at the top end of the slide rod 41, the spring 411 is in an uncontracted state, and the piston plate 410 is at the bottom end of the fixed rod 49.

[0041] The working steps are as follows:

[0042] First, the personnel need to place the rotating head 47 set inside the device at the position where sampling is required, and then the personnel presses the handle 23 downward, so that the handle 23 drives the driving impact rod 25 to move downward synchronously, so that the driving impact rod 25 drives the impact plate 26 to move downward synchronously, so that the impact plate 26 moves downward on the outer wall of the sliding rod three 41, and the impact plate 26 presses downward against the limit plate 42, so that the limit plate 42 drives the slot plate 1 43 to move downward through the sliding rod three 41, so that the slot plate 1 43 drives the sampling tube 1 44 and the sampling tube 2 46 to move downward synchronously, so that the rotating head 47 is inserted into the shallow soil area under the joint action of the sampling tube 1 44 and the sampling tube 2 46, and then the personnel moves the slide plate 37 downward on the outer wall of the sliding rod 1 22, so that the slide plate 37 drives the hinge block 2 38 to move downward synchronously, so that the hinge block 2 38 drives the bottom end of the support rod 36 rotatably connected thereto to begin to flip to the side away from the slide plate 37, so that the bottom end of the support rod 36 drives the hinge block 1 35 rotatably connected thereto to move synchronously away from The movement of one side of the slide plate 37 causes the hinge block 1 35 to drive the fixed block 2 34 to move toward the side away from the groove plate 31, so that the fixed block 2 34 drives the sliding rod 2 33 to slide inside the groove plate 31 until the distance between the ground cone 32 connected to the fixed block 2 34 and the ground is not much different. Then, the personnel presses the groove plate 31 downward by stepping on it, so that the ground cone 32 fixedly connected to the groove plate 31 and it enters the soil. Then, the groove plate 31 drives the fixed block 2 34 to move downward synchronously through the sliding rod 2 33, so that the ground cone 32 fixedly connected to the fixed block 2 34 is completely inserted into the soil, and the device is fixed; the fixed block 2 34 drives the sliding rod 2 33 to extend inside the groove plate 31, so that the fixed position of the ground cone 32 and the soil can be expanded, thereby avoiding the problem of the device being tilted due to the uneven ground, preventing the sampling tube from sampling the soil in an inclined manner, thereby avoiding the deviation of the sampling depth, and thereby improving the diversity of soil samples.

[0043] Then, the personnel control the driving impact rod 25 through the external control device to start working, so that the driving impact rod 25 repeatedly drives the impact plate 26 to push downward against the limit plate 42, so that the limit plate 42 drives the slot plate 1 43 to move downward synchronously through the slide bar 3 41, so that the slot plate 1 43 drives the sampling tube 1 44 to move downward synchronously, so that the sampling tube 1 44 drives the sampling tube 2 46 to move downward synchronously through the screw 45, so that the rotating head 47 moves downward synchronously under the action of the sampling tube 1 44 and the sampling tube 2 46, so that the rotating head 47 moves intermittently toward the inside of the soil ... The soil around the head 47 enters the interior of the rotating head 47 through the filter hole 48, and then enters the interior of the sampling tube 1 44 and the sampling tube 2 46 through the rotating head 47; the stones in the soil are filtered through the filter hole 48, thereby reducing the volume occupied by the stones in the soil sample, improving the ability to obtain sufficient soil during the sampling process, and thus improving the accuracy of the soil monitoring results. At the same time, it also avoids excessive stones from increasing the resistance of the soil, which not only prevents the sampling tube from being difficult to insert to the predetermined depth, but also reduces the workload of the driving impact rod 25, thereby increasing the service life of the equipment.

[0044] When the soil inside the sampling tube 1 44 and the sampling tube 2 46 gradually increases, the air inside the sampling tube 2 46 and the sampling tube 1 44 is compressed, so that the air pressure inside the sampling tube 2 46 and the sampling tube 1 44 increases, and the air pressure inside the sampling tube 2 46 and the sampling tube 1 44 upwardly resists the piston plate 410, so that the piston plate 410 slides vertically upward on the outer wall of the fixing rod 49, so that the piston plate 410 resists the spring 411 and begins to shrink upward until the piston plate 410 moves to a position where it no longer blocks the interior of the sampling tube 1 44 and the sampling tube 2 46. At this time, the interior of the sampling tube 2 46 and the sampling tube 1 44 is The atmospheric pressure enters the air through the gap at the bottom of the piston plate 410 until the air pressure inside the sampling tube 1 44 and the sampling tube 2 46 is the same as the air pressure in the air. At this time, the piston plate 410 moves downward under the elastic action of the spring 411, so that the piston plate 410 moves to the position for sealing the inside of the sampling tube 1 44 and the sampling tube 2 46 again. The sampling tube is intermittently vented by the piston plate 410, which avoids the increase of soil looseness due to excessive air pressure inside the sampling tube and prevents the mixing of soil at the top and the middle of the sampling tube under the action of impact force, thereby ensuring the representativeness of the soil sample.

[0045] Then, the impact rod 25 is driven to repeatedly intermittently punch the top of the sampling tube, so that the sampling tube drives the rotor 47 to intermittently extend into the soil, and then the soil enters the rotor 47 through the filter hole 48 opened on the outer wall of the rotor 47, and then slowly enters the sampling barrel, and finally the soil is collected and sampled.
