The sampling process is cumbersome. Existing soil microorganism samplers are large in size, complex in structure, and inconvenient to carry. In addition, during the sampling process, the soil layer is sampled in the vertical direction. There are problems such as interference of microorganisms at different depths of soil layers on the test results and pollution caused by sample transfer and sealing. Utility Model Content

[0017] The present invention is described in detail below through exemplary embodiments. However, it should be understood that without further description, elements, structures and features in one embodiment may also be beneficially combined in other embodiments.

[0018] A sampler for soil microbial investigation, see Figure 1 ,2 As shown, including:

[0019] The shell 1 is an annular shell with a hollow structure inside. A breaking cutter head 2 is arranged at the bottom end of the shell 1. A pressing plate 3 is arranged horizontally above the shell 1. A sliding rod 4 is vertically connected to the bottom of the pressing plate 3, and the sliding rod 4 is slidably connected to the shell 1. A transmission mechanism is arranged in the shell 1, and the sliding rod 4 is connected to the transmission mechanism. A sampling box 5 is arranged horizontally on the side of the shell 1. The sampling box 5 is slidably connected to the shell 1, and the inner end of the sampling box 5 is connected to the transmission mechanism, so that when the pressing plate 3 is pressed downward, the sampling box 5 extends horizontally outward for sampling.

[0020] Furthermore, the transmission mechanism includes a rack 6 connected to the bottom end of the sliding rod 4, and a fixed seat connected to the bottom of the shell 1, and a gear 8 that can mesh with the rack 6 is rotatably connected to the fixed seat, and the center of the gear 8 is provided with internal teeth. A screw 9 is horizontally arranged on the side of the shell 1, and the screw 9 is threadedly connected to the internal teeth, and the end of the screw 9 is connected to the sampling box 5.

[0021] Furthermore, a spring 10 is connected to the bottom end of the rack 6 . The spring 10 is located inside the housing 1 and fixedly connected to the bottom of the housing 1 .

[0022] Furthermore, the fixing seat includes two vertical support plates 11 , and the vertical support plates 11 are provided with connecting holes. A sleeve 7 is arranged in the connecting hole. The hole diameter of the sleeve 7 is larger than the rod diameter of the screw rod 9 , and the gear 8 is rotatably connected between the two sleeves 7 .

[0023] Furthermore, a test tube 12 is installed inside the sampling box 5 .
