[0033] The following is a specific embodiment of the present invention. People familiar with the technology can easily understand the other advantages and functions of the present invention from the contents disclosed in this specification. Obviously, the described embodiment is a part of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0034] Refer to the instruction manual Figure 1 , a soil sampling device for environmental protection of this embodiment includes a fixing mechanism 1, and also includes:

[0035] The sampling mechanism 2 is arranged on the top of the fixing mechanism 1 and is used for sampling the soil;

[0036] The cleaning mechanism 3 is arranged on both sides of the top of the fixing mechanism 1 and is used for cleaning the outer wall of the sampling mechanism 2 .

[0037] In order to conveniently sample soil at different locations, Figure 2 and Figure 3As shown, the fixing mechanism 1 includes a fixed base plate 101, universal wheels 102 are fixedly installed at the four bottom corners of the fixed base plate 101, a push rod 103 is rotatably installed at one end of the top of the fixed base plate 101, and a fixing frame 104 is fixedly installed on one side of the top of the fixed base plate 101. The staff can use the push rod 103 to move the device on the ground through the universal wheels 102, so that soil sampling operations can be performed on different positions.

[0038] In order to conveniently sample soil at different depths, Figure 2 and Figure 4 As shown, the sampling mechanism 2 includes a mounting plate 201, which is arranged on the outer wall of one side of the fixing frame 104, and hydraulic cylinders 203 are arranged at both ends of the top of the mounting plate 201 close to the fixing frame 104. A rotating shaft 204 is rotatably mounted on the inner wall of the mounting plate 201, and a first motor 205 is arranged on the top of the rotating shaft 204. A spiral sleeve 206 is fixedly mounted on the bottom of the rotating shaft 204, and three feed ports 207 are opened on the inner wall of the bottom of one side of the spiral sleeve 206. The inner wall of the spiral sleeve 206 is rotatably mounted with a first motor 205. A sampling rod 208 is provided with a second motor 209 at the top of the sampling rod 208. A sampling port 210 corresponding to the feed port 207 is provided on the bottom outer wall of one side of the sampling rod 208. The hydraulic cylinder 203 can adjust the depth of the spiral sleeve 206 extending into the ground. The feed port 207 is aligned with the sampling port 210 so that soils at different depths can be sampled. Then, the second motor 209 is operated to stagger the sampling port 210 with the feed port 207, so as to prevent the sampled soil from falling off from the feed port 207.

[0039] In order to prevent the spiral casing 206 from having residual soil and affecting the next sampling work, Figure 2 and Figure 5 As shown, the cleaning mechanism 3 includes two adjusting screw rods 301, and the two adjusting screw rods 301 are respectively arranged on the inner walls at the two ends of the top of the fixed base plate 101, and a third motor 302 is arranged at one end of the adjusting screw rod 301, and a movable plate 304 is arranged on the outer side of the adjusting screw rod 301, and a cleaning brush 305 is fixedly installed on the outer wall of the opposite end of the two movable plates 304. When the third motor 302 is operated, the adjusting screw rod 301 rotates, and the distance between the cleaning brush 305 and the spiral sleeve 206 can be adjusted, so that the cleaning brush 305 can clean the outer wall of the spiral sleeve 206.

[0040] In order to keep the spiral sleeve 206 stable during the lifting process, Figure 2-4As shown, the fixing mechanism 1 includes a movable groove 105, and two movable grooves 105 are provided. The two movable grooves 105 are respectively opened on the inner walls at both ends of the fixing frame 104, and movable seats 202 are fixedly installed at both ends of the outer wall of one side of the mounting plate 201 close to the fixing frame 104. The outer walls of the two movable seats 202 are movably connected to the inner walls of the two movable grooves 105, respectively. The two ends of the top of the fixing frame 104 are respectively fixedly connected to the two hydraulic cylinders 203, and the output ends of the two hydraulic cylinders 203 are respectively fixedly connected to the tops of the adjacent movable seats 202. The movable groove 105 can limit the movement of the movable seat 202, so that the mounting plate 201 remains stable during the movement, and then the spiral sleeve 206 remains stable during the lifting process.

[0041] In order to keep the cleaning brush 305 stable during the adjustment process, Figure 2-3 and Figure 5 As shown, the fixing mechanism 1 includes a mounting groove 106, and two mounting grooves 106 are provided. The two mounting grooves 106 are respectively opened on the inner walls at both ends of the top of the fixed base plate 101, and the inner walls of the two mounting grooves 106 are respectively rotatably connected to the two adjusting screw rods 301, and the bottoms of the two movable plates 304 are fixedly installed with sliders 303, and the inner walls of the sliders 303 are threadedly connected to the outer walls of the adjacent adjusting screw rods 301, and the outer walls of the sliders 303 are movably connected to the inner walls of the adjacent mounting grooves 106. The mounting grooves 106 can limit the movement of the sliders 303, so that the movable plate 304 remains stable during the movement, and the cleaning brush 305 can stably clean the outer wall of the spiral sleeve 206.

[0042] In order to stably carry out soil sampling operations at different depths, such as Figure 2 and Figure 4 As shown, the three feed ports 207 and the three sampling ports 210 are arranged at equal intervals, and the front vertical section area size of the feed port 207 is the same as the front vertical section area size of the sampling port 210. By aligning the feed port 207 with the sampling port 210, soil at different depths can be sampled, and then the sampling port 210 is rotated to be staggered with the feed port 207, so that the sampled soil can be stored inside the sampling port 210.

[0043] In order to facilitate the adjustment of the position of the sampling port 210, Figure 2 and Figure 4 As shown, the top of the inner wall of the spiral sleeve 206 is fixedly connected to the second motor 209, and the second motor 209 is connected to the top of the sampling rod 208 through an output shaft transmission. The inner wall of the spiral sleeve 206 can be used to install and fix the second motor 209. The operation of the second motor 209 can drive the sampling rod 208 to rotate, and then the corresponding relationship between the sampling port 210 and the feed port 207 can be adjusted, so that the soil can be sampled conveniently.

[0044] The specific implementation scenario is as follows: in environmental protection work, it is necessary to sample and test the soil. The staff uses the push rod 103 to make the device move on the ground through the universal wheel 102, so that the soil at different positions can be sampled. The first motor 205 works to make the rotating shaft 204 rotate, thereby making the spiral sleeve 206 rotate. At the same time, the two hydraulic cylinders 203 work to make the two movable seats 202 move downward along the inner walls of the two movable grooves 105 respectively, so that the mounting plate 201 can move along the fixed The outer wall of one side of the fixed frame 104 moves downward, so that the spiral sleeve 206 can penetrate into the soil, so that the surface soil can enter the bottom sampling port 210 through the bottom feed port 207. As the spiral sleeve 206 continues to penetrate, the deep soil can enter the high sampling port 210 through the high feed port 207. When the three sampling ports 210 are completely filled, the sampling rod 208 is rotated by the second motor 209, so that the distance between the sampling port 210 and the feed port 207 can be adjusted. The corresponding relationship between the sampling port 210 and the feeding port 207 can prevent the soil sampled inside the sampling port 210 from falling off from the feeding port 207 during the removal process of the spiral sleeve 206, and at the same time, it can ensure that the sampled soil can be stably taken out from the soil. At the same time, as the spiral sleeve 206 is taken out by rising, the two third motors 302 work to make the two adjusting screw rods 301 rotate, so that the two sliders 303 can be respectively moved along the inner walls of the two mounting grooves 106 on the outside of the two adjusting screw rods 301. The movable plates 304 can be moved, and the distance between the two movable plates 304 and the spiral sleeve 206 can be adjusted, so that the two cleaning brushes 305 can clean the outer wall of the spiral sleeve 206, so that the spiral sleeve 206 can be kept clean during the next soil sampling process, and the residual soil can be prevented from affecting the subsequent sampling work, and the efficiency and quality of soil sampling can be improved. This embodiment specifically solves the problem that the soil sampling device in the prior art cannot conveniently sample soil at different levels, and the residual soil will affect the subsequent soil sampling work.

[0045] Although the utility model has been described in detail above with general descriptions and specific embodiments, it is obvious to those skilled in the art that some modifications or improvements can be made to the utility model. Therefore, these modifications or improvements made without departing from the spirit of the utility model are within the scope of protection claimed by the utility model.
