The middle part of the sampling rod is hollow, and a material taking port for extracting biological bacterial fertilizer in the bacteria cultivation box is opened on one side of the lower part of the sampling rod, and a material taking piece for accommodating biological bacterial fertilizer is connected inside the material taking port" and so on.

[0004] However, it is found in the implementation of the related technology that the above technical solution has the following problems: Although it achieves the effect of facilitating the sampling and detection of biological bacteria at different depths through the provided technical solution, when sampling biological bacteria at different depths, it is necessary to perform multiple sampling operations for biological bacteria at different depths. The operation is relatively cumbersome and time-consuming, and it is not convenient to complete the sampling operation of biological bacteria at different depths simultaneously at one time, thus reducing the overall efficiency and convenience of the sampling work. Content of the Utility Model

[0026] Next, in combination with the embodiments of the present utility model, the technical solutions in the embodiments of the present utility model will be clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts fall within the scope of protection of the present utility model. Embodiment 1

[0027] Please refer to Figure 1 - Figure 4 , a biological bacterial fertilizer detection device provided by the present utility model includes: a holding rod 1 and a sampling rod 2 fixedly connected to one end of the holding rod 1. Inner cavities communicating with each other are provided in both the sampling rod 2 and the holding rod 1;

[0028] A plurality of sampling ports 3 opened on the surface of the sampling rod 2 and evenly distributed along its length direction;

[0029] A movable rod 4 penetrating through the plurality of sampling ports 3 and sliding inside them;

[0030] A piston block 5 fixedly connected to one end of the movable rod 4 and in contact with the inner wall of the sampling port 3. The piston block 5 moves in the sampling port 3 through a movement mechanism provided in the inner cavity;

[0031] A chute is provided in the holding rod 1, and a baffle 7 for blocking the sampling port 3 is slidably connected in the chute;

[0032] The moving mechanism includes a magnet block 6 fixedly connected to one end of the movable rod 4, a rotating shaft rod 8 rotatably connected to the inner bottom wall of the cavity, a first magnetic strip 9 embedded on one side of the surface of the rotating shaft rod 8 and repelling the magnet block 6 with the same pole, a second magnetic strip 10 embedded on the other side of the surface of the rotating shaft rod 8 and magnetically connected to the magnet block 6, and a limiting component provided at one end of the rotating shaft rod 8 to prevent its rotation.

[0033] The technical solution provided in this embodiment is as follows: During sampling and detection, by holding the holding rod 1, the sampling rod 2 is inserted into the biological bacteria in the bacteria incubator. Then, the baffle 7 is lifted upward to expose the sampling port 3, and the rotating shaft rod 8 is rotated 180 degrees to drive the positions of the second magnetic strip 10 and the first magnetic strip 9 to be swapped. At the same time, the position of the rotating shaft rod 8 is fixed by the limiting component, so that the second magnetic strip 10 is aligned with the magnet block 6. Under the action of the second magnetic strip 10, the magnet block 6 is adsorbed on the surface of the rotating shaft rod 8, and the movable rod 4 and the piston block 5 are driven to move. Thus, the sample is sucked into the sampling port 3 through the piston block 5. Then, the baffle 7 is lowered to scrape off the excess sample on the surface of the sampling rod 2 and block the sampling port 3 to prevent the sample from falling during the process of taking out the sampling rod 2. At the same time, the holding rod 1 is lifted upward to take out the sampling rod 2. Finally, the baffle 7 is moved to pour the samples in the sampling port 3 one by one for detection. Therefore, it can achieve the effect of simultaneously sampling biological bacteria at different depths in one sampling process, avoiding the phenomenon of repeated sampling multiple times when detecting biological bacteria at different depths, and effectively improving the efficiency and effect of the sampling work.

[0034] Further, the limiting component includes a spring 11 fixedly connected to one end of the rotating shaft rod 8 and a limiting block 12 fixedly connected to one end of the spring 11. A limiting groove 13 engaged with the limiting block 12 is formed at one end of the holding rod 1.

[0035] The limiting block 12 has a linear structure, and the limiting groove 13 has the same shape as the limiting block 12.

[0036] Specifically, when rotating the rotating shaft rod 8 for sampling, the limiting block 12 is lifted upward to stretch the spring 11, so that the limiting block 12 and the limiting groove 13 are separated. Then, the limiting block 12 is rotated to drive the rotating shaft rod 8 to rotate 180 degrees, so that the positions of the second magnetic strip 10 and the first magnetic strip 9 are swapped. Thus, the second magnetic strip 10 adsorbs the magnet block 6 to move the piston block 5 for sampling. Then, the limiting block 12 is released, and the spring 11 drives the limiting block 12 to reset and engage with the limiting groove 13, achieving the purpose of limiting and fixing the rotating shaft rod 8 to prevent its rotation from affecting the sampling effect.

[0037] Further, a drill bit 14 is fixedly connected to one end of the sampling rod 2. The baffle 7 has an L-shaped structure, and the inner wall of its horizontal section is arc-shaped.

[0038] Specifically, by setting the drill bit 14, it is convenient for the sampling rod 2 to smoothly insert into the biological bacteria during sampling and to insert into different depths inside the biological bacteria.

[0039] Furthermore, a plurality of anti-slip rib blocks are fixedly installed on the surface of the holding rod 1, and the plurality of anti-slip rib blocks are evenly distributed around the surface of the holding rod 1 in a circular form.

[0040] Specifically, by setting the anti-slip rib blocks, it is convenient to prevent the phenomenon of hand slipping when a person holds the holding rod 1 for sampling, and the stability during the sampling process is ensured. Embodiment 2

[0041] Based on Embodiment 1, in this embodiment: an adsorption mechanism for fixing the holding rod 1 is provided on the surface of the holding rod 1.

[0042] The adsorption mechanism includes mounting blocks 15 symmetrically and fixedly installed on both sides of the surface of the holding rod 1 and suction cups 16 fixedly connected to one side surface of the mounting blocks 15.

[0043] The technical solution provided by this embodiment is: when the sampling rod 2 is inserted into the bacteria incubator for sampling, by keeping the holding rod 1 in a vertical state and pressing the suction cup 16 against the bacteria incubator for fitting, the holding rod 1 can be adsorbed and fixed under the action of the suction cup 16, which is convenient for ensuring that the sampling rod 2 can vertically extend into the biological bacteria for sampling, and improves the sampling effect and convenience.

[0044] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
