DETAILED DESCRIPTION

[0061] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments 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.

[0062] The specific implementation of the present invention is described in detail below in conjunction with specific embodiments.

[0063] See also Figure 1-Figure 13 A soil microorganism detection sampler provided in an embodiment of the present invention comprises a sampling drill tube 6, a drill bit 7 is detachably mounted on the bottom end of the sampling drill tube 6, and further comprises:

[0064] The sampling telescopic part 8 is located on the sampling drill tube 6 and is connected to the sampling chamber 19 provided in the sampling drill tube 6. The sampling telescopic part 8 is also provided with a telescopic opening 13;

[0065] A transverse sampling box 14, which is inserted into the telescopic opening 13 and is slidably connected to the telescopic opening 13;

[0066] and a sampling control mechanism, the sampling control mechanism is respectively connected to the transverse sampling box 14 and the sampling chamber 19, and is connected to the sampling drill tube 6, wherein the sampling control mechanism includes a telescopic drive component and an opening and closing sampling control component;

[0067] The telescopic drive assembly is located in the sampling chamber 19 and is connected to the sampling drill tube 6 . The telescopic drive assembly is also connected to the transverse sampling box 14 . The opening and closing sampling control assembly is connected to the transverse sampling box 14 and to the inner wall of the sampling chamber 19 .

[0068] See also Figure 1-Figure 13 There are four sampling telescopic parts 8, each of which is provided with a telescopic opening 13 on the side, and each of which is provided with a transverse sampling box 14 in the telescopic opening 13. Adjacent transverse sampling boxes 14 are vertically arranged. Before reaching the sampling position, the four transverse sampling boxes 14 are all retracted in the sampling chamber 19 to form a square structure.

[0069] When sampling the soil, first, the staff can place the drill bit 7 on the ground of the designated sampling area, and use an external drive device to drive the sampling drill tube 6 and the drill bit 7 into the soil. Then, after the sampling telescopic part 8 reaches the designated depth position, the telescopic drive component is started, wherein the telescopic drive component can be driven manually or mechanically, and the human-driven method is preferred. The telescopic drive component will drive four horizontal sampling boxes 14 to move in the telescopic opening 13 at the same time, and move toward the outside of the sampling drill tube 6 at the same time, so as to sample the horizontal position at the designated depth position, and four samples can be collected at the same time to ensure the accuracy of the subsequent soil microorganism detection results, wherein the end of the horizontal sampling box 14 is provided with a soil-breaking cutter head 15 to ensure that the horizontal sampling box 1 4 can be smoothly extended into the soil for sampling. In the process of the lateral sampling box 14 extending outward for sampling, the sampling control assembly is set. On the one hand, the sampling drill tube 6 and the drill bit 7 can be extended into the soil. Since the lateral sampling box 14 blocks the telescopic opening 13 and the sampling position of the sampling control assembly is blocked, the soil at other positions can be completely prevented from entering the sampling position, thereby ensuring that the soil samples collected subsequently are not contaminated. On the other hand, the sampling control assembly can control the opening and closing time of multiple sampling positions and the opening and closing order of multiple sampling positions, which can not only avoid cross contamination of soil samples, but also realize sampling operations at multiple depth positions, and can collect multiple soil samples at the same time each time, thereby ensuring the accuracy of the sampling results and providing convenience for the sampling work of the staff.

[0070] In one embodiment of the present invention, see Figure 1-Figure 13 , the telescopic drive assembly comprises:

[0071] A driving gear 20, the driving gear 20 is rotatably mounted in the middle of the sampling chamber 19;

[0072] Driven gears 21, the number of the driven gears 21 is four, the four driven gears 21 are all rotatably mounted in the sampling chamber 19, and are all meshed and connected with the driving gear 20;

[0073] A swing rod 23, one end of which is fixedly connected to the driven gear 21, and the other end of which is provided with a movable notch 24;

[0074] And a linkage sliding post 30 , wherein the linkage sliding post 30 is fixedly mounted on the transverse sampling box 14 , and the linkage sliding post 30 is also inserted into the movable slot 24 and slidably connected with the movable slot 24 .

[0075] It also includes: a sampling control rotating rod 10, the bottom end of which is fixedly connected to the driving gear 20, and the other end of which passes through the sampling drill tube 6 and is rotatably connected to the sampling drill tube 6;

[0076] And a foldable handle 12 , wherein the foldable handle 12 is fixedly mounted on the top end of the sampling control rotating rod 10 .

[0077] After the sampling telescopic part 8 reaches the sampling depth, the sampling drill tube 6 and the drill bit 7 stop moving downward, and the staff opens the foldable handle 12 in the folded state, and then manually rotates the foldable handle 12, thereby driving the sampling control rotating rod 10 to rotate in the sampling drill tube 6. During the rotation of the sampling control rotating rod 10, the driving gear 20 can be driven to rotate, and multiple driven gears 21 can be driven to rotate synchronously, and the driven gear 21 can drive the swing rod 23 to rotate a certain angle in the sampling chamber 19. When the swing rod 23 rotates, under the action of the active notch 24 and the linkage slide column 30, the horizontal sampling box 14 can be driven to move toward the outside of the sampling drill tube 6 in the telescopic opening 13, so that the sampling operation can be performed on the horizontal position of the specified position, and through the synchronous movement of the four horizontal sampling boxes 14 to the outside, four samples can be taken at the same depth position at the same time to ensure the accuracy of the subsequent sample detection results. No more details will be given here.

[0078] In one embodiment of the present invention, see Figure 1-Figure 13 , the opening and closing sampling control component comprises:

[0079] A fixed support rod 22, wherein the fixed support rod 22 is fixedly connected to the inner wall of the sampling chamber 19;

[0080] A position controller 31, wherein the position controller 31 is fixedly mounted on the other end of the fixed support rod 22, and a connecting rod 32 is fixedly mounted on the output end of the position controller 31;

[0081] A station adjustment slider 25, wherein the station adjustment slider 25 is slidably mounted on the transverse sampling box 14 and is fixedly connected to the connecting rod 32;

[0082] An L-shaped blocking rod 26, one end of which is fixedly connected to the station adjustment slider 25;

[0083] and a telescopic opening and closing unit, wherein the number of the telescopic opening and closing units is two sets, and the two sets of the telescopic opening and closing units are both located on the same transverse sampling box 14 and are respectively detachably connected to the L-shaped blocking rod 26;

[0084] When one set of the telescopic opening and closing units contacts the L-shaped blocking rod 26 , the other set of the telescopic opening and closing units contacts the adjacent transverse sampling box 14 .

[0085] The telescopic opening and closing unit comprises:

[0086] A movable rod 27, the movable rod 27 is inserted into the horizontal sampling box 14 and is slidably connected to the horizontal sampling box 14, and an arc-shaped smooth head 28 is fixedly installed on the other end of the movable rod 27;

[0087] An L-shaped slide bar 34, the L-shaped slide bar 34 is slidably mounted in the transverse sampling box 14 and fixedly connected to the movable bar 27;

[0088] A spring 37, two ends of which are fixedly connected to the transverse sampling box 14 and the L-shaped slide bar 34 respectively;

[0089] And a sample storage module, wherein the sample storage module is connected to the horizontal sampling box 14 and connected to the L-shaped sliding rod 34.

[0090] The sample storage module comprises:

[0091] A sample inlet 16, wherein the sample inlet 16 is opened on the horizontal sampling box 14;

[0092] A sample containing chamber 33, wherein the sample containing chamber 33 is fixedly installed in the transverse sampling box 14 and communicated with the sample inlet 16;

[0093] A flip portion 36, wherein the flip portion 36 is rotatably connected to the inner wall of the transverse sampling box 14, and a flip cover 17 is fixedly mounted on the flip portion 36, and the flip cover 17 is detachably connected to the sample inlet 16;

[0094] and a driving portion 35 , wherein the driving portion 35 is fixedly connected to the L-shaped sliding rod 34 and connected to the flipping portion 36 .

[0095] Before the four transverse sampling boxes 14 move toward the outside of the sampling drill tube 6 at the same time, the position controller 31 can be started by the staff to drive the connecting rod 32 to move upward or downward, thereby driving the station adjustment slider 25 and the L-shaped blocking rod 26 to move synchronously to control the working state of the two sets of telescopic opening and closing units, wherein the two sets of telescopic opening and closing units have the same structure and working mode (the following content is an example of the way in which the sample inlet 16 located on the upper side of the transverse sampling box 14 is opened for sampling, such as Figure 5-Figure 13 As shown in the figure, only when one set of the telescopic opening and closing units contacts the L-shaped baffle 26, the other set of the telescopic opening and closing units contacts the adjacent transverse sampling box 14, that is, one set is in an extended state, and the other set is in a contracted state under the limiting action of the L-shaped baffle 26, wherein the other set of telescopic opening and closing units includes a sample inlet 218 and a movable rod 29, etc. When the arc-shaped smooth head 28 on the movable rod 27 contacts the adjacent transverse sampling box 14 and slides on the adjacent transverse sampling box 14, as the spacing between the adjacent transverse sampling boxes 14 increases, under the pulling force of the spring 37, the spring 37 will drive the L-shaped slide bar 34 to slide in the transverse sampling box 14 toward the outside direction of the transverse sampling box 14 (that is, move toward the direction of the adjacent transverse sampling box 14), At this time, the driving part 35 will pull the flip part 36 to rotate on the horizontal sampling box 14, and drive the flip cover 17 to open the sample inlet 16 (wherein, the driving part 35 and the flip part 36 can adopt a gear meshing transmission structure, so that when the driving part 35 moves, the flip part 36 can be pushed to rotate, and the contact time between the teeth on the driving part 35 and the teeth on the flip part 36 can be designed, that is, only a part of the teeth is provided on the driving part 35, and the other parts are smooth planes, so that after the horizontal sampling box 14 moves a certain distance toward the outside of the telescopic opening 13, the driving part 35 drives the flip part 36 to flip and open the flip cover 17, and when the horizontal sampling box 14 retracts, the driving part 35 drives the flip cover 17 to close quickly, thereby ensuring smooth soil collection, which will not be described in detail here). Fig.10 and Fig.12As shown, during this process, the arc-shaped smooth head 28 on the movable rod 29 contacts the L-shaped blocking rod 26. At this time, under the blocking effect of the L-shaped blocking rod 26, the movable rod 29 is always retracted in the horizontal sampling box 14, and the sample inlet 18 is always in a closed state, so as to prevent the soil at this depth from entering the sample inlet 18 when the soil sample is collected at the sample inlet 16. After the sampling at this depth is completed, the sampling control lever 10 is rotated in the reverse direction by human power, so that the four horizontal sampling boxes 14 can be restored to their original positions (that is, the four horizontal sampling boxes 14 are simultaneously retracted in the sampling chamber 19). In the process of the horizontal sampling boxes 14 returning to their original positions, the flip cover 17 blocks the sample inlet 16 again to prevent the collected samples from leaking out. When sampling at another depth position, the sampling drill tube 6 and the drill bit 7 continue to move downward. After reaching the specified position, the position controller 31 is started. The position controller 31 can be in the form of an electric push rod or an electromagnet. Under the pulling action of the position controller 31, the connecting rod 32 can drive the station adjustment slider 25 to slide upward on the horizontal sampling box 14, so that the L-shaped stopper 26 can contact the arc-shaped smooth head 28 on the movable rod 1 27, and the arc-shaped smooth head 28 on the movable rod 29 can contact the adjacent horizontal sampling box 14. , thereby ensuring that when sampling at another depth, the sample inlet 16 is in a closed state, while the sample inlet 2 18 is in an open sampling state (wherein, when the sample inlet 2 18 is in an open sampling state, since the structure of the sample inlet 2 18 is the same as that of the sample inlet 16, the sample inlet 2 18 is also provided with a flip cover 17. After the flip cover 17 on the sample inlet 2 18 is opened, the soil around the horizontal sampling box 14 will flow under its own gravity and the disturbance of the sampling device, and fill in The sample inlet 16 and the sample inlet 2 are located near the sample inlet 18, and then, as the lateral sampling box 14 retracts, the driving unit 35 drives the flip cover 17 to close. The flip cover 17 can push the soil into the sample inlet 18 and seal the sample inlet 18, so that the soil sampling work at different depths can be completed smoothly). Since the sample inlet 16 and the sample inlet 2 are on different planes, the cross contamination of soil samples at different depths can be avoided during the sampling process, and the soil at two depths can be sampled in one process of sampling deep into the soil. Among them, the arc-shaped smooth head 28 is set. When the arc-shaped smooth head 28 contacts the surface of the lateral sampling box 14, there are gaps on the upper and lower sides between the arc-shaped smooth head 28 and the lateral sampling box 14. Since the arc-shaped smooth head 28 is an arc-shaped structure, it is convenient for the L-shaped baffle 26 to smoothly change the working position, so as to realize the opening and closing of the sample inlet 16 and the sample inlet 2 at different depths, thereby avoiding the cross contamination of soil samples at different depths.

[0104] and a display panel 2, wherein the display panel 2 is located on the sampling support 1 and is electrically connected to the opening and closing sampling control component.

[0105] After reaching the soil sampling position, the drill bit 7 is brought into contact with the ground, and the driving motor 11 is started to drive the rotating transmission member 9 to rotate, wherein the rotating transmission member 9 can adopt a gear meshing transmission structure, thereby driving the sampling drill tube 6 to rotate on the sampling bracket 1, and the sampling bracket 1 is provided with a handrail, and the staff can control the stability of the drill bit 7 and the sampling drill tube 6 drilling into the soil.
