[0004] However, in actual use of the above-mentioned soil sampler, when sampling the soil, the operator needs to manually put the soil of different depths into the sample bottle, and for soil sampling in some special environments, the soil needs to be promptly put into a sealed bottle for sealing. The operation of the device is relatively cumbersome, which reduces the convenience of the device. For this reason, the applicant proposed a soil sampler. Utility Model Content

DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] In environmental testing, soil sampling and analysis are often required, so a soil sampler is needed. In actual use, most traditional soil samplers require the collected soil to be taken out of the device, and the operator scrapes off the outer wall of the collected soil, and then divides the collected soil and fills it into sample cans in turn. This process is relatively cumbersome, which reduces the convenience of the device and the rate of soil sampling. For this reason, the applicant proposes a soil sampler.

[0025] like Figure 1-Figure 7As shown, the utility model provides a technical solution: a soil sampler, including a soil sampling spring 1, the bottom end of the soil sampling spring 1 contacts with a sampling mechanism 2, the sampling mechanism 2 includes a plurality of groups of fixing rings 201, connecting tubes 202 are fixed to opposite ends of adjacent fixing rings 201, an opening is provided on one side of the outer wall of the connecting tube 202, and slide rods 203 are fixed to both sides of the opening of the outer wall of the connecting tube 202, a shovel plate 204 is slidably connected between the two slide rods 203, a rotating tube 205 is connected to the outer walls of adjacent fixing rings 201 for common rotation, notches are provided on both sides of the outer wall of the rotating tube 205, soil discharge tubes 206 are fixed to both sides of the inner wall of the rotating tube 205, and spatula frames 207 are fixed to the soil inlet ends of the two soil discharge tubes 206, and two limit plates are fixed between the adjacent fixing rings 201. 208, a plurality of oblique teeth 209 are fixed on the inner wall of the fixing ring 201, a drilling mechanism 3 is clamped at the bottom of the sampling mechanism 2, the sampling mechanism 2 is located inside the drilling mechanism 3, a positioning frame 4 is fixed at the bottom of the drilling mechanism 3, the opposite ends of adjacent connecting pipes 202 are respectively threadedly clamped with connecting frames 210, the top of the connecting frame 210 located at the outermost top is closed, and the closed part of the top is in contact with the bottom end of the soil sampling spring 1, the inner walls of the notches opened on both sides of the outer wall of the rotating tube 205 are respectively clamped with sealing strips 211, one side of the outer wall of adjacent soil discharge pipes 206 is in contact with the back sides of the adjacent limiting plates 208, the distance between the frame openings of adjacent spatula frames 207 is smaller than the distance between the two adjacent limiting plates 208, and the soil discharge ends of the two soil discharge pipes 206 correspond to the two notches of the rotating tube 205 respectively.

[0026] It should be noted that: when sampling the soil, the hydraulic cylinder 302 is first started to make several drill teeth 307 contact with the ground, and then the motor 303 is started to drive the drilling mechanism 3 to rotate. At the same time, the hydraulic cylinder 302 is also continuously stretched, so that the threaded drill bit 305 and the threaded conveying tube 304 drill the soil. At this time, the sample soil will first pass through the feed pipe 306 to the bottom of the connecting tube 202, and enter the fixed ring 201 through the connecting tube 202. At this time, the soil will form tooth-like patterns on the outer wall due to several oblique teeth 209. At this time, the inner walls of two of the tooth-like patterns will contact the outer walls of the two adjacent spatula frames 207, and the two will not affect each other. At the same time, in order to ensure the stability of the sample soil during collection, the opposite surfaces of the two adjacent limit plates 208 will contact them. As the drilling mechanism 3 continues to go deeper, the sample soil will also be in several rotating tubes 205. When the soil is collected, under the action of the drilling mechanism 3, the threaded conveying tube 304 and the threaded drill bit 305 away from the ground, then the operator disassembles the threaded conveying cylinder 304 through the clamping part of the motor 303 and the threaded conveying cylinder 304, and then disassembles the threaded conveying cylinder 304 through the clamping part of the threaded conveying cylinder 304 and the threaded drill bit 305, then the operator needs to push a plurality of shovel plates 204 to make a plurality of rotating tubes 205 in a sealed state, then rotate the rotating tube 205, because there are two fixing rings 2 inside the plurality of rotating tubes 205. 01, and because the inner walls of the two fixing rings 201 are fixed with a plurality of oblique teeth 209, the spatula frame 207 cuts off the outer wall of the sample soil inside the rotating tube 205, and the soil will not move due to the rotation of the rotating tube 205. Afterwards, the cut soil will enter the soil discharge pipe 206. When cleaning, the sealing strip 211 can be removed to clean the soil inside the soil discharge pipe 206, and finally, the plurality of rotating tubes 205 can be removed one by one by twisting the connecting frame 210.

[0027] like Figure 6-Figure 7 As shown, the utility model provides a technical solution: a soil sampler, including a drilling mechanism 3, the drilling mechanism 3 includes a fixing frame 301, a hydraulic cylinder 302 is fixed on the top of the fixing frame 301, a motor 303 is fixed after the output end of the hydraulic cylinder 302 passes through the top of the fixing frame 301, a threaded conveying tube 304 is clamped on the output end of the motor 303, a threaded drill bit 305 is clamped on the tube mouth at the bottom of the threaded conveying tube 304, a hole is opened at the center position of the top of the threaded drill bit 305, a feed pipe 306 is fixed on the inner wall of the hole of the threaded drill bit 305, a plurality of drill teeth 307 are fixed on the feed end of the feed pipe 306, the top of the inner wall of the threaded conveying tube 304 is fixed to the top of the soil sampling spring 1, the top of the threaded drill bit 305 is clamped with the outermost bottom connecting frame 210 in the sampling mechanism 2, and the discharge end of the feed pipe 306 is connected to the outermost bottom connecting frame 210 in the sampling mechanism 2.

[0028] It should be noted that the positioning frame 4 can help the operator to clearly identify the drilling point, and because the drilling mechanism 3 is fixed on the positioning frame 4, the stability of the drilling mechanism 3 can also be further improved.

[0029] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is limited by the attached embodiments and their equivalents.
