Description

Technical Field

[0001] This utility model relates to the field of sampling device technology, and more specifically to a soil seed bank sampling device. Background Technology

[0002] Soil sampling is fundamental to soil seed bank research. Due to the highly uneven distribution of seeds in the soil, extensive sampling is necessary during this process. Soil samplers are typically used for sampling, such as CN219434379U-Soil Sampler, CN221594349U-A Soil Sampler, CN222393810U-Loose Soil Sampling Cylinder, and CN103424279A-Soil Sampler.

[0003] However, existing soil sampling devices require the soil sample to be removed after drilling into the soil layer with a single drill bit before the next sampling can be carried out. This makes the multi-point sampling operation cumbersome and inefficient.

[0004] Therefore, how to provide a soil seed bank sampling device that can improve the efficiency of multi-point sampling is a problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0005] In view of this, the present invention provides a soil seed bank sampling device that can improve the efficiency of multi-point sampling.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A soil seed bank sampling device, comprising:

[0008] Sampling cylinders, wherein multiple sampling cylinders are detachably connected end to end;

[0009] A handle, the lower end of which is detachably connected to the upper end of any of the sampling tubes.

[0010] As can be seen from the above technical solution, compared with the prior art, this utility model discloses a soil seed bank sampling device. This device contains multiple sampling tubes, each of which can be individually sampled by attaching a handle. For example, after sampling with one sampling tube, the handle can be detached from the tube containing the soil sample and attached to another empty sampling tube, allowing sampling at other locations. This significantly improves the efficiency of multi-point sampling and effectively avoids the problems of traditional soil sampling devices, which require removing the soil sample after drilling into the soil layer with a single drill bit before proceeding to the next sampling operation. This addresses the cumbersome and inefficient nature of multi-point sampling. Furthermore, multiple sampling tubes and handles can be assembled together for easy portability before and after sampling.

[0011] Furthermore, the sampling tube includes:

[0012] A soil sample collection tube, wherein the internal cavity of the soil sample collection tube is a soil sample holding cavity, the lower end of the soil sample collection tube is a soil inlet and outlet communicating with the soil sample holding cavity, and the upper end of the soil sample collection tube is sealed with a cover plate.

[0013] A connecting seat, the bottom of which is fixedly connected to the top of the soil sample collection tube, the top of which is detachably connected to the bottom of the adjacent soil sample collection tube, and the lower end of the handle is detachably connected to any one of the connecting seats.

[0014] The beneficial effects of adopting the above technical solution are as follows: by setting a connecting seat on the soil sample collection tube, it is possible to connect two adjacent soil sample collection tubes end to end and to connect the handle to the soil sample collection tube at the head end, so that the multiple parts of the device are connected into a whole structure, which is convenient for carrying the device before and after sampling; moreover, the handle can also be connected to a single soil sample collection tube through the connecting seat to assemble into a traditional sampling device to realize soil sample collection.

[0015] Furthermore, the top of the connecting seat is provided with a first internal thread hole, and the bottom outer wall of the soil sample collection cylinder is provided with a first external thread. The first internal thread hole on the connecting seat is threadedly connected to the first external thread on the adjacent soil sample collection cylinder.

[0016] The beneficial effects of adopting the above technical solution are: the use of threads between two adjacent soil sampling tubes enables quick assembly and disassembly, making it easy for outdoor sampling personnel to perform convenient assembly and disassembly operations.

[0017] Furthermore, a second internal threaded hole is provided on the bottom surface of the first internal threaded hole, and a second external thread is provided on the outer wall of the handle, and the second internal threaded hole is threadedly connected to the second external thread.

[0018] The beneficial effect of adopting the above technical solution is that it makes it easy for outdoor sampling personnel to conveniently assemble and disassemble the handle with any soil sampling tube.

[0019] Furthermore, the soil sample receiving cavity is provided with a soil sample ejection plate, and the cover plate is provided with a through hole arranged coaxially with the second internal thread hole. The lower end of the handle can pass through the through hole and abut against the top surface of the soil sample ejection plate.

[0020] The beneficial effects of adopting the above technical solution are as follows: When it is necessary to remove the soil sample from the soil sample receiving cavity, simply turn the handle. Because the handle is threadedly connected to the connecting seat, the handle can be inserted into the soil sample receiving cavity and push the soil sample ejection plate to move. The soil sample ejection plate can then push the soil sample out of the soil sample receiving cavity through the soil inlet and outlet. Therefore, the handle of this device can not only serve as a force-applying rod to press the sampling tube into the soil during sampling, but also as a force-applying rod to push the soil sample ejection plate to move when removing the soil sample. That is, this device can achieve the dual functions of sampling and removal with a single handle, avoiding the problem of existing sampling devices requiring both a handle and a push rod, resulting in a larger number of structural components and a more complex structure.

[0021] Furthermore, a positioning groove is provided on the top surface of the soil sample ejection plate, and the lower end of the handle is inserted into the positioning groove.

[0022] The beneficial effects of adopting the above technical solution are: it makes it easy for the handle to apply force evenly to the soil sample ejection plate, facilitates the smooth movement of the soil sample ejection plate, and prevents jamming. Attached Figure Description

[0034] See Figures 1-6 As shown in the figure, this utility model embodiment discloses a soil seed bank sampling device, characterized in that it includes:

[0035] Sampling cylinders, wherein multiple sampling cylinders are detachably connected end to end;

[0036] A handle, the lower end of which is detachably connected to the upper end of any of the sampling tubes.

[0037] In a specific embodiment, the sampling tube includes:

[0038] The soil sample collection tube 11 has an internal cavity that serves as a soil sample receiving cavity 111. The lower end of the soil sample collection tube 11 is a soil inlet / outlet 112 that communicates with the soil sample receiving cavity 111. The upper end of the soil sample collection tube 11 is sealed with a cover plate 113.

[0039] The bottom of the connecting seat 12 is fixedly connected to the top of the soil sample collection tube 11, and the top of the connecting seat 12 is detachably connected to the bottom of the adjacent soil sample collection tube 11. The lower end of the handle 2 is detachably connected to any one of the connecting seats 12.

[0040] The top of the connecting seat 12 is provided with a first internal thread hole 121, and the bottom outer wall of the soil sample collection cylinder 11 has a first external thread. The first internal thread hole 121 on the connecting seat 12 is threadedly connected to the first external thread on the adjacent soil sample collection cylinder 11.
