[0002] Ecological environmental monitoring refers to the activities of environmental monitoring agencies to monitor and measure environmental quality. Environmental monitoring is to monitor and measure indicators that reflect environmental quality to determine the level of environmental pollution and environmental quality. Therefore, in order to ensure the ecological and environmental safety of each region, it is necessary to conduct sampling surveys on air, soil, and other aspects.

[0003] Since soil sampling is required, soil sampling equipment will be used. When sampling, it is necessary to go vertically down into the soil. Each layer of soil samples is different, so sometimes it is necessary to sample soil at different depths. At this time, if sampling is repeated due to depth issues, it will easily affect the convenience of sampling. Utility Model Content

[0004] The purpose of the utility model is to provide a soil sampling device for ecological environment monitoring, so as to solve the problem that there are differences in each layer of soil samples proposed in the above background technology. Therefore, sometimes it is necessary to sample soil samples at different depths. At this time, if sampling is repeated due to depth issues, it is easy to affect the convenience of sampling.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical scheme: a soil sampling device for ecological environment monitoring, comprising a working frame and a base plate, mounting plates are installed on both sides of the inner wall of the working frame, a threaded rod is installed on the top of one of the mounting plates, and a guide rod is installed on the top of the other mounting plate, the outer wall of the guide rod is connected with a guide sleeve, the outer wall of the threaded rod is connected with a threaded block, the top of the threaded rod is connected with a servo motor, a connecting rod is installed on one side of the guide sleeve and the threaded block, a top plate is installed on one side of the connecting rod, a working motor is installed on the top of the top plate, a transmission disk is connected to the output end of the working motor, a connecting block is installed on the bottom end of the transmission disk, a sampling barrel is connected to the bottom end of the connecting block, a storage cavity is formed inside the sampling barrel, a connecting groove is opened inside the top end of the sampling barrel, and an injection hole is installed at a peripheral position of the connecting groove inside the top end of the sampling barrel.

[0006] Preferably, the injection holes are symmetrically distributed about the central axis of the connecting groove, and a threaded connection is formed between the connecting groove and the connecting block.

[0007] Preferably, a threaded connection is formed between the threaded block and the threaded rod, and the connecting rod is symmetrically distributed about the central axis of the top plate.

[0008] Preferably, the bottom end of the injection hole is communicated with the interior of the storage chamber, and a docking plate is installed at the bottom end of the sampling cylinder, and the docking plate is used for connection and installation with the connecting block.

[0009] Preferably, base plates are installed on both sides of the bottom end of the working frame, the base plates are symmetrically distributed about the central axis of the working frame, and threaded grooves are opened inside the base plates.

[0010] Preferably, an insertion rod is connected to the inside of the threaded groove, a rotating handle is fixed to the top end of the insertion rod, and a ground insertion block is fixed to the bottom end of the insertion rod.

[0011] Preferably, the thread grooves are distributed in two groups inside the bottom plate, and a threaded connection is formed between the insertion rod and the thread groove.

[0013] Compared with the prior art, the beneficial effects of the utility model are: the soil sampling device for ecological environment monitoring not only improves the convenience of multi-layer sampling, but also improves the bottom stability and adjustment and protection capabilities of the soil sampling device;

[0014] (1) After the servo motor is started, the threaded rod can be driven to rotate. At this time, after the threaded rod rotates, the threaded block cooperates with it. At the same time, after the guide sleeve and the guide rod cooperate to guide, the top plate can be vertically moved under the connection of the connecting rod. Therefore, after the height of the top plate is moved, the sampling tube and the whole body can be deeply embedded in the soil. According to needs, the connection work of the multi-layer sampling tube can be completed by using the connection block and the connection groove. Then, after the sampling tube is deeply embedded in the ground, the working motor is started to drive the transmission disk and the sampling tube to rotate as a whole. After the rotation, the soil gradually becomes loose, and the soil will penetrate from the position of the sampling hole and be collected inside the storage chamber. Therefore, the convenience of the overall multi-layer sampling is better improved during the work process;

[0015] (2) The working frame and the bottom plate are fixedly connected, and then the bottom plate is used to support the bottom. When supporting, the insertion rod cooperates with the bottom insertion block to be inserted into the soil. The handle is held and rotated. After rotation, the insertion rod cooperates with the threaded groove, so that the insertion block can gradually penetrate into the soil, thereby better improving the overall bottom stability during the work process;

[0016] (3) During the vertical movement of the top plate, a through slot is opened inside the work frame. The opening of the through slot can facilitate the insertion of the working motor. At the same time, when the working motor reaches the inside of the through slot, the buffer block can be used to protect the side of the working motor to prevent the working motor from rubbing against the inner wall of the through slot. Therefore, the overall insertion protection capability is better improved during the working process. BRIEF DESCRIPTION OF THE DRAWINGS
