DETAILED DESCRIPTION

[0035] The preferred embodiments of the present application will be described in detail with reference to the drawings, however the present application can be realized in various different forms, therefore the present application is not limited to the embodiments described below, and in order to more clearly describe the present application, components not connected with the invention will be omitted from the drawings;

[0036] The technical solutions in the embodiments of the present application are to solve the problems in the above background art, and the general idea is as follows:

[0037] Embodiment:

[0038] Please refer to Figures 1-6 The present embodiment introduces the specific structure of a soil parameter detection device, which includes a sampling bucket 2, and the top of the sampling bucket 2 is detachably installed with a bucket cover 14. Considering that the soil needs to be poured into the sampling bucket 2 for sampling, a pouring hole is arranged on one side of the top of the bucket cover 14, and a sealing cover 15 is hingedly installed on one side of the pouring hole. Considering that sealing is needed during sampling, a sealing plug is fixedly installed on one side of the sealing cover 15. In order to facilitate the pouring of soil, a first handle 16 is fixedly installed on one side of the top of the sealing cover 15. The sealing cover 15 is rotated by the first handle 16, which facilitates the pouring of soil into the sampling bucket 2, and at the same time, the sealing plug is sealed, preventing soil leakage during sampling and affecting the detection results.

[0039] In order to improve the accuracy of the detection result, the soil in the sampling barrel 2 needs to be stirred when sampling the soil. The bottom center of the barrel cover 14 is fixedly installed with a first electric telescopic rod 17. One end of the first electric telescopic rod 17 is fixedly installed with a first driving motor 18. The driving end of the first driving motor 18 is connected with a driving column 19. The two sides of the driving column 19 are installed with a first stirring column 20. The bottom of the driving column 19 is fixedly installed with a second stirring column 21. The first electric telescopic rod 17 is controlled to stretch and retract, and the first driving motor 18 is controlled to move up and down, so that the first stirring column 20 and the second stirring column 21 move to the appropriate position. The first driving motor 18 is controlled to operate, so that the driving column 19 drives the first stirring column 20 and the second stirring column 21 to rotate, the soil is stirred, the soil from different positions is mixed uniformly, and the accuracy of the detection is improved. During the stirring process, the first electric telescopic rod 17 can also be controlled to move up and down, so that the soil is more uniformly mixed, and the accuracy of the detection is further improved.

[0040] In order to further improve the uniformity of the soil from different positions, the first stirring column 20 is obliquely arranged on the two sides of the driving column 19, and the oblique angle is 30 degrees with the horizontal plane. The second stirring column 21 is vertically installed at the bottom of the driving column 19. The oblique arrangement of the first stirring column 20 causes the soil at the bottom to turn over, so that the soil is more uniformly mixed, and the accuracy of the detection is improved.

[0041] When the soil is detected, it needs to be air dried. If it is naturally air dried, it needs a long time. Ventilation holes are symmetrically arranged on the two sides of the sampling barrel 2. One side of the two ventilation holes is respectively installed with a suction and blowing integrated machine 22. The upper and lower sides of the suction and blowing integrated machine 22 are detachably fixedly connected with the sampling barrel 2 through supporting rods. One of the two suction and blowing integrated machines 22 blows air, and the other one sucks air, so that the air in the sampling barrel 2 flows, and the soil is air dried, improving the sampling efficiency of the soil. In order to prevent some substances in the soil from being lost during the air drying process and affecting the detection result, a filter membrane is detachably fixedly installed on the other side of the two ventilation holes. The filter membrane is made of polytetrafluoroethylene film. The polytetrafluoroethylene film has strong hydrophobicity and can withstand 200℃. It is suitable for pretreatment of soil samples containing organic solvents and can intercept microorganisms such as bacteria, fungi and volatile organic compounds. After the soil is air dried, the two suction and blowing integrated machines 22 blow air respectively or simultaneously, blow the filtered substances on the filter membrane into the soil, and then stir the first stirring column 20 and the second stirring column 21 to mix the soil uniformly, further improving the accuracy of the detection.

[0042] Considering that the soil needs to be divided several times by quartering, and the final reserved soil sample can represent the overall characteristics of the original mixed sample by multiple sub-division, this process reduces the influence of local unevenness through uniform mixing and scientific sampling, the first arc block 3 is symmetrically and fixedly installed at the bottom of the sampling barrel 2, two first arc blocks 3 are fixedly connected, two second arc blocks 4 are symmetrically and slidably installed on the two sides of the two first arc blocks 3, in order to make the soil more uniformly distributed on the first arc block 3 and the second arc block 4, the first arc block 3 and the second arc block 4 are the same size, two first arc blocks 3 and two second arc blocks 4 form a cylinder, a plurality of pressure sensors are arranged at the top of the two first arc blocks 3 and the two second arc blocks 4, for detecting the weight of the soil falling on the first arc block 3 and the second arc block 4, when the weight of the soil is approximately the same, it means relatively uniform, considering that two of the quartered soils need to be separated, the connecting block 5 is fixedly installed at the bottom of the two second arc blocks 4, the second electric telescopic rod 6 is fixedly installed at the top center of the connecting circular plate 8.

[0043] Considering that the soil on the first arc block 3 may fall off from the first arc block 3 and fall onto the second arc block 4 when the second arc block 4 moves up and down, affecting the accuracy of detection, by controlling the operation of the two suction and blowing integrated machines 22, blowing air into the sampling barrel 2 to create pressure, giving the surface of the soil a certain pressure, at the same time, by controlling the extension of the second electric telescopic rod 6, the second arc block 4, the inner wall of the sampling barrel 2 and the pressure cooperate with each other to slightly shape the first arc block 3, preventing the soil on the first arc block 3 from falling off into the second arc block 4 during the up and down movement of the second arc block 4, even if the soil on the first arc block 3 falls off slightly, it will not cause a fundamental impact on the final detection result, and the first electric telescopic rod 17 can also be controlled to operate, so that the second stirring column 21 presses on the surface of the soil, further preventing the soil from falling off.

[0044] In view of the fact that the above operation needs to be carried out multiple times when carrying out the quartering method, the bottom of the sampling barrel 2 is fixedly connected with a separation barrel 7, the bottom of the separation barrel 7 is fixedly connected with a circular plate 8, the top center of the circular plate 8 is symmetrically installed with a garbage can 9, two garbage cans 9 are arranged at the bottom of two second arc-shaped blocks 4, the top of the two garbage cans 9 is installed with a connecting plate 10, the side of the connecting plate 10 is fixedly installed with a connecting rod 11 which is detachably connected with the inner wall of the separation barrel 7 for supporting, the side of the connecting plate 10 is fixedly installed with a third electric telescopic rod 12, one end of the third electric telescopic rod 12 is detachably connected with a push plate 13, by operating the second electric telescopic rod 6, the second arc-shaped block 4 is moved downward, when the top of the second arc-shaped block 4 is on the same plane as the bottom of the push plate 13, by controlling the third electric telescopic rod 12 to operate, the soil on the second arc-shaped block 4 is pushed into the garbage can 9.

[0045] In view of the fact that the soil will fall off during the pushing process of the push plate 13, three limiting plates 28 are fixedly installed on the side of the connecting plate 10, the three limiting plates 28 are respectively slidably connected with the top of the garbage can 9 and the detection equipment body 1, the distance between the two adjacent limiting plates 28 is slightly greater than the radius of the second arc-shaped block 4, the length of the limiting plate 28 is the same as or slightly greater than the radius of the second arc-shaped block 4, by limiting the second arc-shaped block 4 with the limiting plate 28, the soil is prevented from falling off from the two sides of the second arc-shaped block 4 during the pushing process of the push plate 13, so as to pollute the equipment, and at the same time, the push plate 13 and the limiting plate 28 are high enough to prevent the soil from accumulating in front of the push plate 13 and scattering to the back or both sides of the push plate 13 during the pushing process, so as to pollute the equipment.

[0046] When the soil on the second arc-shaped block 4 all enters the garbage can 9, the second electric telescopic rod 6 is controlled to stretch, so that the second arc-shaped block 4 is moved upward until it is flush with the first arc-shaped block 3, and the above operation is repeated.

[0047] When the pressure value detected by the two pressure sensors on the two first arc-shaped blocks 3 reaches the preset interval after multiple quartering methods are carried out, it means that the quartering method is completed, the two first arc-shaped blocks 3 are fixedly connected with a first communication pipe 23, one end of the first communication pipe 23 is connected with the inlet end of a soil suction machine 24, the outlet end of the soil suction machine 24 is connected with a second communication pipe 25, the second communication pipe 25 is connected with the detection equipment body 1, the two detection equipment bodies 1 are symmetrically installed at the top of the connecting circular plate 8, by controlling the soil suction machine 24 to operate, the soil to be detected is introduced into the detection equipment body 1 for detection.

[0048] Considering that the first communication pipe 23 is connected with the first arc-shaped block 3 through and through, in order to prevent the first communication pipe 23 from affecting the operation of the four-part method, an electric valve is installed at the connection between the first communication pipe 23 and the first arc-shaped block 3, when the pressure value detected by the pressure sensor reaches the preset range, the electric valve is opened, cooperating with the operation of the soil suction machine 24, wherein the first electric telescopic rod 17, the second electric telescopic rod 6, the third electric telescopic rod 12, the electric valve and the controller are connected, and are controlled through the controller.

[0049] The two sides of the separation barrel 7 are symmetrically hinged with a movable door 26, the movable door 26 is arc-shaped, and the movable door 26 is sealingly connected with the separation barrel 7 through a sealing element, which can be a sealing plug or a sealing ring, one side of the movable door 26 is provided with a second handle 27, the movable door 26 is opened through the second handle 27, and then the soil in the garbage can 9 and the detection equipment body 1 is taken out for reuse.

[0050] As described above, the two suction-blowing integrated machines 22 cooperate with each other to dry the soil, thereby improving the drying efficiency. The filter membrane made of polytetrafluoroethylene film is detachably and fixedly installed on one side of the two ventilation holes. After the soil is dried, the two suction-blowing integrated machines 22 blow air respectively or simultaneously, and the filtered substances on the filter membrane are blown off into the soil. Then, the first stirring column 20 and the second stirring column 21 are driven to stir the soil, so that the soil is uniformly mixed, thereby improving the detection accuracy. Then, the soil weight on the first arc-shaped block 3 and the second arc-shaped block 4 is detected by the plurality of pressure sensors. When the error between the weights of the four parts of soil is within the preset range, it means that the soil is divided into four parts. Then, the second electric telescopic rod 6, the third electric telescopic rod 12 and the push plate 13 cooperate to perform multiple automatic operations, thereby improving the sampling efficiency and the detection efficiency.

[0051] When the soil is divided into four parts, the two suction-blowing integrated machines 22 are controlled to operate simultaneously to blow air into the sampling barrel 2 to generate pressure and give the surface of the soil a certain pressure. At the same time, the second electric telescopic rod 6 is controlled to stretch, and the inner walls of the second arc-shaped block 4 and the sampling barrel 2 cooperate with the pressure to slightly shape the soil on the first arc-shaped block 3, so as to prevent the soil on the first arc-shaped block 3 from falling off into the second arc-shaped block 4 during the downward movement of the second arc-shaped block 4, thereby affecting the accuracy of the detection result.

[0052] Then, the first stirring column 20 is obliquely arranged on both sides of the driving column 19, the oblique angle is 30 degrees with the horizontal plane, and the second stirring column 21 is vertically arranged at the bottom of the driving column 19, so that the bottom of the soil is turned upside down, and the soil is mixed more uniformly, thereby improving the detection accuracy.

[0053] Finally, by setting the distance between the two adjacent limiting plates 28 to be slightly greater than the radius of the second arc-shaped block 4, and setting the length of the limiting plate 28 to be the same as or slightly greater than the radius of the second arc-shaped block 4, the second arc-shaped block 4 is limited by the limiting plate 28, so that the soil is prevented from separating from the two sides of the second arc-shaped block 4 during the process of pushing the soil by the push plate 13, and the equipment is prevented from being contaminated. At the same time, the push plate 13 and the limiting plate 28 are set to be high enough, so that the front part of the push plate 13 is prevented from being accumulated and scattered to the rear part or the two sides of the push plate 13 during the process of pushing the soil, and the equipment is prevented from being contaminated.

[0054] Finally, it should be noted that: obviously, the above embodiments are only examples for clearly illustrating the present application, and are not limitations on the embodiments. Based on the above description, those skilled in the art can also make other different forms of changes or variations. Here, it is not necessary and impossible to enumerate all the embodiments. The obvious changes or variations derived therefrom are still within the protection scope of the present application.
