Description

Technical Field

[0001] This utility model relates to the field of sampling and collection technology, and in particular to a sampling and collection device. Background Technology

[0002] Soil sampling is a fundamental step in obtaining soil information. Collecting representative soil samples using scientific methods provides a basis for soil analysis, agricultural management, and environmental monitoring. Sampling typically employs strategies such as diagonal sampling, checkerboard sampling, or serpentine sampling, combined with tools like soil drills and shovels. Samples are collected from multiple points at a specified depth (e.g., 0-20cm of topsoil) and mixed, then reduced to the required amount using the quartering method.

[0003] Existing sampling and collection equipment, especially portable ones, can only collect soil samples from a single depth. When collecting samples from different depths, the equipment must be changed, which is cumbersome, labor-intensive, and inefficient. Furthermore, the collected soil can only be temporarily stored in the equipment, preventing the collection of other soil samples. Exposure to outside air may also alter the soil properties, leading to inaccuracies in soil testing. To overcome these disadvantages, this invention provides a sampling and collection device.

[0006] Furthermore, one end of the conveying pipe is provided with an internal thread, and the collection box is provided with an external thread. The collection box is threadedly connected to one end of the conveying pipe through the external thread.

[0007] Furthermore, the first connecting assembly includes a first fixing groove fixedly connected to one end of the first spiral conveying rod, a first fixing hole is provided on one side of the first fixing groove, a first fixing bolt is threadedly connected to the first fixing hole, a first insert is fixedly connected to one end of the second spiral conveying rod, a second fixing hole is provided on one side of the first insert, and the second fixing hole and the first fixing bolt are threadedly connected.

[0008] Furthermore, the second connecting assembly includes a second fixing groove fixedly connected to one end of the second spiral conveying rod, a third fixing hole opened on one side of the second fixing groove, a second fixing bolt threadedly connected to the third fixing hole, a second insert fixedly connected to one side of the drill bit, a fourth fixing hole opened on one side of the second insert, and the fourth fixing hole and the second fixing bolt threadedly connected.

[0009] Furthermore, one end of the collection tube is fixedly connected with several tooth tips.

[0010] Furthermore, a handle is rotatably connected to one end of the collection tube, and one end of the handle passes through the collection tube and is fixedly connected to one end of the first spiral conveying rod.

[0011] The beneficial effects of this utility model are:

[0012] In use, this invention uses a first connecting component and a second component to sample soil at the required depth. A certain number of second spiral conveying rods are added between the drill bit and the first spiral conveying rod, thereby enabling the collection of soil samples at different depths. The collected soil is collected using a collection box, allowing the device to collect samples from multiple locations and store them to avoid contamination. Furthermore, different drill bits can be used to adapt to different soil types during collection. Attached Figure Description
