[0028] Refer to Figures 1-4, an embodiment provided by the present utility model: an environmental protection acceptance sampling device, including a bottom plate 1, a sample loading assembly 2, a lifting assembly 3, a sampling assembly 4, rollers 5, and a pusher 6. The sample loading assembly 2 includes a first baffle 21, which is fixedly connected to the bottom plate 1. A funnel 22 is fixedly connected to the first baffle 21. A first feeding port 23 is opened on the first baffle 21. A second baffle 24 is slidably connected inside the first baffle 21. A second feeding port 25 is opened on the second baffle 24. A material cylinder 26 is fixedly connected to the bottom of the second baffle 24. The material cylinder 26 is a hollow cylinder. A cover plate 27 is hinged to the bottom of the material cylinder 26. An L-shaped plate 28 is fixedly connected to the bottom of the first baffle 21. A cylinder 29 is fixedly connected to the L-shaped plate 28. The output end of the cylinder 29 is fixedly connected to the material cylinder 26. A sample container 210 is fixedly connected to the bottom plate 1, and the sample container 210 is located directly below the material cylinder 26. The lifting assembly 3 includes a first limiting frame 31, which is fixedly connected to the bottom plate 1. A first movable frame 32 is slidably connected to the first limiting frame 31. The first limiting frame 31 limits the first movable frame 32. A screw rod 33 is threadedly connected to the first limiting frame 31. One end of the screw rod 33 is fixedly connected to a first helical gear 34. The first helical gear 34 is meshed with a second helical gear 35. The second helical gear 35 is fixedly connected to a rotating shaft 36. The rotating shaft 36 is rotatably connected to the first movable frame 32. One end of the rotating shaft 36 is fixedly connected to a crank 37. A second limiting frame 38 is fixedly connected to the bottom plate 1. A second movable frame 39 is slidably connected to the second limiting frame 38. The second limiting frame 38 limits the second movable frame 39. A connecting rod 310 is fixedly connected between the first movable frame 32 and the second movable frame 39. The connecting rod 310 is used to receive soil.
[0029] The sampling assembly 4 includes a motor 41, which is fixedly connected to the connecting rod 310. The connecting rod 310 is fixedly connected to a sampling cylinder 42. The sampling cylinder 42 penetrates through the connecting rod 310. The sampling cylinder 42 is a hollow cylinder. The output end of the motor 41 is fixedly connected to an auger 43. The motor 41 provides the power for the rotation of the auger 43.
[0030] A discharge port 44 is fixedly connected to the side of the auger 43. The discharge port 44 is communicated with the inside of the auger 43.
[0031] The auger 43 is arranged inside the sampling cylinder 42.
[0032] The funnel 22 is located directly below the discharge port 44.
[0033] Rollers 5 are installed at the four corners of the bottom of the bottom plate 1. A pusher 6 is installed on the bottom plate 1. The rollers 5 and the pusher 6 facilitate the operator to move the sampling device.
[0034] Working principle: The operator moves the sampling device to a suitable position and turns the crank 37, driving the second helical gear 35 and the rotating shaft 36 to rotate. The second helical gear 35 drives the first helical gear 34 and the screw 33 to rotate. The screw 33 rotates and descends on the first limiting frame 31. The screw 33 then drives the first helical gear 34, the second helical gear 35, the rotating shaft 36, the first movable frame 32, the first movable frame 32, the connecting rod 310, and the second movable frame 39 to descend. The sampling cylinder 42 and the auger 43 are inserted into the soil sample to be measured. Then the operator starts the motor 41. The motor 41 drives the auger 43 to rotate. The auger 43 breaks up the soil and conveys it upward along the sampling cylinder 42. When the soil is conveyed to the top, it falls into the funnel 22 from the discharge port 44, and then falls into the material cylinder 26 through the first feed port 23 on the first baffle 21 and the second feed port 25 on the second baffle 24. At this time, the material cylinder 26 is above the L-shaped plate 28. The cover plate 27 is blocked by the cylinder 29 and fits with the bottom of the material cylinder 26. The material cylinder 26 is filled with soil. The operator starts the cylinder 29. The cylinder 29 pushes the material cylinder 26 away from the L-shaped plate 28. When the material cylinder 26 leaves the L-shaped plate 28, the second baffle 24 blocks the first feed port 23 to prevent the soil from falling below the first baffle 21 and polluting the device. The cover plate 27 is turned over and separated from the material cylinder 26 under the action of the gravity of the soil and itself. The soil falls from the material cylinder 26 into the sample container 210, thus completing a quantitative sampling. When sampling soil at other depths is required, the operator continues to rotate the crank 37 to control the lifting of the sampling assembly 4 and the lifting assembly 3.
[0035] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
