[0029] By twisting the rotating ring 305, the rotating shaft 301 can be driven to rotate, which can drive the spiral conveying blade 302 to rotate. When the device is inserted into the interior of the microbial fertilizer, the rotating spiral conveying blade 302 can accelerate the flow of the fertilizer, so that it can be transported through the inner side of the mounting plate 102 through the spiral conveying blade 302 and introduced into the internal storage of the sample collection component 2, thereby achieving the purpose of sampling.

[0030] like Figure 1-Figure 7 As shown, the connecting component 31 includes a top rod 3103 fixedly connected to the bottom of the connecting block 303, the lower end of the top rod 3103 extends to the inner side of the mounting shell 104, the surface of the top rod 3103 is fixedly connected with evenly distributed fixing blocks, an adjusting cavity is opened inside the fixing block, the inner wall of the adjusting cavity is slidably connected with a limiting rod 3105, one end of the limiting rod 3105 passes through the fixing block, and a second spring 3106 is fixedly connected between the other end of the limiting rod 3105 and the inner wall of the adjusting cavity.

[0031] A connecting cavity 3104 is provided inside the push rod 3103, a through hole connected to the adjusting cavity is provided on the inner wall of the connecting cavity 3104, a connecting channel 3102 connected to the connecting cavity 3104 is provided inside the connecting block 303, and a flow channel 3101 connected to the connecting channel 3102 is provided inside the rotating shaft 301.

The upper end of the adjusting rod 3110 passes through the rotating shaft 301 and is fixedly connected to a pull block 3111.

[0033] A third spring 3109 is sleeved on the surface of the adjusting rod 3110 , one end of the third spring 3109 is fixedly connected to the surface of the extrusion plate 3108 , and the other end of the third spring 3109 is fixedly connected to the inner wall of the liquid storage chamber 3107 .

[0034] Under normal conditions, the extrusion plate 3108 squeezes the hydraulic oil stored in the liquid storage chamber 3107 under the action of the third spring 3109, so that the hydraulic oil is injected into the connecting chamber 3104 through the flow channel 3101 and the connecting channel 3102, and then injected into the adjusting chamber through the through hole, thereby pushing the limit rod 3105 to extend from the inside of the fixed block. In this process, the second spring 3106 is stretched, and the pulling block 3111 can be lifted up to drive the extrusion plate 3108 to move upward under the action of the adjusting rod 3110, so that the space between the bottom of the extrusion plate 3108 and the inside of the liquid storage chamber 3107 is increased and the third spring 3109 is compressed. At this time, the second spring 3106 can drive the limit rod 3105 to shrink to the inside of the adjusting chamber and squeeze the hydraulic oil in the adjusting chamber through the through hole, the connecting chamber 3104, the connecting channel 3102 and the flow channel 3101 to be guided back to the inside of the liquid storage chamber 3107 for storage. After releasing the pulling block 3111, it can be reset under the action of the third spring 3109, so that the limit rod 3105 extends out of the adjusting chamber again.

[0035] like Figure 1-Figure 7 As shown, the sample collecting component 2 includes a mounting ring 206 which is slidably connected to the inner side of the mounting shell 104, the inner side of the mounting ring 206 is fixedly connected to a connecting shell 207, the lower end of the connecting shell 207 passes through the mounting shell 104, and the surface of the connecting shell 207 is provided with an external thread, the inner side of the connecting shell 207 is fixedly connected to a mounting block 208, the surface of the mounting block 208 is provided with a mounting hole, the inner wall of the mounting hole is fixedly connected to a ring-shaped spacer block 210, and a guide groove is formed between the two spacer blocks 210.

[0036] The inner wall of the mounting hole is provided with a limiting hole 209 located inside the guide groove.

[0037] A blocking block 213 located below the mounting block 208 is provided on the inner side of the connecting shell 207. The cross-sectional shape of the blocking block 213 is conical. The surface of the blocking block 213 is fixedly connected with evenly distributed fixing plates 214. The top of the fixing plate 214 is fixedly connected with a connecting column 212. The upper end of the connecting column 212 is slidingly connected to the inner wall of the mounting block 208. The inner wall of the connecting column 212 is fixedly connected with a first spring 211. The upper end of the first spring 211 passes through the connecting column 212 and is fixedly connected to the inner wall of the mounting block 208.

[0038] Align the mounting shell 104 with the mounting ring 206 and insert it into the interior of the mounting shell 104. During this process, the guide groove can guide the position of the fixed block, so that after installation, the limiting rod 3105 can be inserted into the limiting hole 209 to complete the connection with the mounting block 208. During the installation process, the upper lifting block 3111 shrinks the limiting rod 3105 to avoid affecting the insertion of the fixed block into the guide groove. During the process of inserting the mounting ring 206 into the interior of the mounting shell 104, the push rod 3103 can push the blocking block 213 downward, so that the blocking block 213 can be separated from the mounting hole, so that the sample can pass through the mounting hole and the blocking block 213. During the process of separating the blocking block 213 from the mounting hole, the connecting column 212 can limit its position and stretch the first spring 211 at the same time. During disassembly, the blocking block 213 can be inserted into the interior of the mounting hole and close to its inner wall under the action of the first spring 211, thereby achieving a self-sealing effect.

[0039] like Figure 1-Figure 7 As shown, the sample collecting assembly 2 also includes a base 204 disposed below the connecting shell 207 , a connecting groove is provided on the top of the base 204 , an internal thread is provided on the inner wall of the connecting groove, and evenly distributed support plates 205 are fixedly connected to the surface of the base 204 .

[0040] A plurality of connecting tubes 201 are arranged between the connecting shell 207 and the base 204 . The top of the connecting tube 201 is provided with a thread groove 202 . The bottom of the connecting tube 201 is fixedly connected with a connecting piece 203 . The outer side of the connecting piece 203 is provided with an external thread.

[0041] A corresponding number of connecting tubes 201 are selected according to the sampling requirements, wherein one connecting tube 201 can be threadedly connected to the thread groove 202 of another connecting tube 201 through a connecting piece 203, and the connecting shell 207 can be threadedly connected to the thread groove 202 on the top connecting tube 201 through an external thread arranged on the surface, and the connecting piece 203 of the bottom connecting tube 201 can be threadedly connected to the connecting groove of the base 204, and different numbers of samples can be stored by changing the connection of different numbers of connecting tubes 201. The operation is simple, and the sample passing through the connecting shell 207 can be introduced into the inner side of the connecting tube 201 for storage, and after the sampling is completed, the automatic sealing effect can be achieved by separating the mounting ring 206 and the mounting shell 104, and the staff does not need to touch the sample collecting component 2, thereby avoiding the influence of the strains in the microbial fertilizer on the human body.

[0042] Working principle: According to the sampling requirements, the sampling volume can be adjusted by docking different numbers of connecting tubes 201. During installation, first lift the pull block 3111 to shrink the limit rod 3105 to the inside of the adjustment cavity, and then align the mounting shell 104 with the mounting ring 206 to insert it into the mounting shell 104. After the insertion is in place, release the pull block 3111 and reset it under the action of the third spring 3109, so that the limit rod 3105 can be extended from the adjustment cavity again, and the limit rod 3105 can be inserted into the inside of the limit hole 209 to complete the limitation of the sample collection component 2. The sample collection component 2 is inserted into the microbial fertilizer through the connecting rod 1. By twisting the rotating ring 305, the rotating shaft 301 can be driven to rotate, which can drive the spiral conveying blade 302 to rotate. When the device is inserted into the microbial fertilizer, the rotating spiral conveying blade 302 can accelerate the flow of the fertilizer, so that it can be transported through the inner side of the mounting disk 102 through the spiral conveying blade 302 and introduced into the internal storage of the sample collecting component 2 to achieve the purpose of sampling. After the sampling is completed, the automatic blocking effect can be achieved by separating the mounting ring 206 and the mounting shell 104. There is no need for the staff to touch the sample collecting component 2, thereby avoiding the influence of the bacteria in the microbial fertilizer on the human body.
