Description

Technical Field

[0001] The utility model relates to the technical field of soil sampling devices, in particular to an environmental monitoring soil sampler. Background Art

[0002] A soil sampler is a tool used to obtain soil samples. Currently, soil sampling is used to collect soil samples in all soil experiments and rock surveys. A soil sampler is an effective test tool for agricultural workers or geological surveyors to study the distribution of soil at different depths, organic matter content, soil moisture content and other data.

[0003] For example, patent application No. CN202020234962.4 discloses a soil monitoring and sampling device for environmental protection projects, whose structure includes a handle, an air pusher, a pushing rod, a grab plate, a sampling tube, and a pedal. The utility model provides a soil monitoring and sampling device for environmental protection projects. When some soils have strong adhesion and partially adhere to the inner wall of the sampling tube, the push rod on the outer shell can be pressed to push the cleaning scraper ring to slide on the inner wall of the outer shell, so that the air push block on the air push groove is pressurized, and the gas is pushed to the sliding groove through the ventilation pipe, so that the pressure block extends out and contacts the telescopic soft layer and the inner wall of the outer shell. In the process of sliding down, the soil adhered to the inner wall is cleaned and pushed out. By improving the structure of the equipment, the equipment can better scrape and clean some soil adhered to the inner wall of the sampling tube when it is in use, and push it out of the sampling tube.

[0004] After sampling, this structure can scrape off the soil attached to the inner wall by pressing the push rod, but this structure still requires too many manual operation steps when sampling and discharging samples, and the steps cannot be simplified, resulting in inconvenience in operation. At the same time, the fixed position of the foot pedal of this structure leads to poor applicability. Therefore, professionals in this field provide an environmental monitoring soil sampler to solve the above-mentioned problems. Utility Model Content

[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0022] See also Figures 1 to 4 In the utility model, an environmental monitoring soil sampler comprises a sampling rod 1, a cavity 2 is provided inside the sampling rod 1, a handle 3 is fixedly connected to the top of the sampling rod 1, a movable column 4 is slidably connected to the inner wall of the cavity 2, a reset spring 5 is fixedly connected to the top of the movable column 4, and the top of the reset spring 5 is fixedly connected to the inner wall of the cavity 2, movable grooves 6 are provided on the left and right sides of the sampling rod 1, the interior of the movable groove 6 is communicated with the interior of the sampling rod 1, a synchronous cylinder 7 is fixedly connected to the top of the movable column 4, the reset spring 5 is located inside the synchronous cylinder 7, and an extension rod 8 is fixedly connected to the left and right sides of the synchronous cylinder 7, the extension rod 8 passes through the movable groove 6 and extends to the outside of the sampling rod 1, a threaded sleeve 9 is rotatably connected to the outer wall of the sampling rod 1, a threaded tube 10 is slidably connected to the outer wall of the sampling rod 1, the outer wall of the threaded tube 10 is threadedly connected to the inner wall of the threaded sleeve 9, and a pedal 16 is hinged on the threaded tube 10.

[0023] The bottom end of the sampling rod 1 is fixedly connected with an insert 14, and the surface of the insert 14 is smooth.

[0024] When it is necessary to sample the soil, the user holds the handle 3 so that the sampling rod 1 is at the top of the sampled soil, and then the user inserts the insert 14 into the soil to facilitate the subsequent user to exert force. Then the user rotates the threaded sleeve 9, and the threaded tube 10 threadedly connected to the inner wall of the threaded sleeve 9 begins to move downward, thereby driving the pedal 16 to move downward. As the user continues to rotate the pedal 16, it moves to a suitable position and then stops rotating. At this time, the height of the pedal 16 is suitable for the user. The user holds the handle 3 with both hands and then steps on the pedal 16 to send the sampling rod 1 downward. At this time, the soil is When the sampling rod 1 enters the cavity 2, the movable column 4 begins to move upward by the thrust, and the reset spring 5 begins to contract and generate an opposite force. At this time, the synchronous cylinder 7 drives the extension rod 8 to slide inside the movable groove 6 close to the user's hand. When the soil is entered, the extension rod 8 is close to the user's hand. The user can hold the extension rod 8 with his fingers. At this time, the movable column 4 remains stable, and then the user pulls the sampling rod 1 out of the soil. When the soil needs to be taken out, the user releases the extension rod 8. At this time, the reset spring 5 rebounds and pushes the movable column 4 to slowly push out the soil sample, so that environmental protection monitoring can be carried out through the soil.

[0025] In the utility model, soil sampling for environmental monitoring is achieved through the cooperation of the sampling rod 1 and the insert 14. At the same time, the vertical pedal 16 on the sampling rod 1 can adjust the height according to different users and usage situations to find a suitable force point to improve practicality. In addition, a movable column 4 supported by a reset spring 5 is arranged inside the sampling rod 1. When sampling downward, the soil will press the movable column 4 to make the reset spring 5 produce an opposite force. Then, when taking out, the limit on the reset spring 5 can be released to completely take out the soil inside the sampling rod 1, thereby reducing the number of operating steps for personnel.

[0026] See also Figure 1 and 3 , wherein: a push rod 11 is fixedly connected to the outer wall of the threaded sleeve 9, and the push rod 11 is provided with evenly distributed anti-slip patterns.

[0027] In the utility model, when the user needs to rotate the threaded sleeve 9, the protruding push rod 11 can provide a good fulcrum for the user, and the anti-slip pattern can prevent the user from slipping, thereby enabling the user to better adjust the threaded sleeve 9.

[0028] See also Figure 4 , wherein: the movable column 4 is in a hollow state, and evenly distributed reinforcing rods 12 are fixedly connected to the inner wall of the movable column 4.

[0029] In the utility model, the hollow movable column 4 can reduce the weight of the entire device, and the reinforcing rod 12 improves the integrity and durability of the movable column 4, saving costs and reducing the burden on personnel when using it.

[0030] See also Figure 1 , wherein: a guide groove 13 is opened on the outer wall of the sampling rod 1, and the threaded tube 10 is slidably connected to the inner wall of the guide groove 13.

[0031] In the utility model, the setting of the guide groove 13 can limit the threaded tube 10, so that the threaded tube 10 is always located at the outer ring of the sampling rod 1 to maintain stable movement in the vertical direction.

[0032] See also Figure 4 , wherein: a sealing ring 15 is fixedly connected to the bottom of the outer side of the movable column 4 , and the sealing ring 15 is slidably connected to the inner wall of the cavity 2 .

[0033] In the utility model, when the movable column 4 moves vertically in the cavity 2, the sealing ring 15 will also move accordingly. The sealing ring 15 can prevent the sampled soil from entering the top of the movable column 4 through the gap, and can also scrape off the soil attached to the inner wall of the cavity 2 when discharging the soil.

[0034] The above is a preferred specific implementation of the utility model; however, the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the utility model according to the technical solution and its improved conception of the utility model, which should be included in the protection scope of the utility model.
