Description

Technical Field

[0001] The utility model relates to the technical field of soil sample collection equipment, in particular to a soil sample collector. Background Art

[0002] Soil sampling refers to the samples taken during the soil testing process. A hole is dug at the sampling point as needed, and then the sample is collected using a collector. It is also one of the main sampling methods for soil testing. Through sampling, the soil composition and land health status can be clearly analyzed in the laboratory, facilitating timely response.

[0003] The inner walls of current collectors are all flat, and the soil is brought out from underground by relying on the expansion of the soil inside the collector. This method easily causes the soil to fall out of the collector, affecting the collection effect. In addition, the current collection length is generally fixed. Some can be extended by adding a connecting rod, but the connecting rod is generally connected by a thread, which does not change when assembled or disassembled. Moreover, the collector will be rotated during the collection process, which easily loosens the connecting rod. Therefore, a soil sample collector is proposed. Utility Model Content

[0020] A slot 12 is provided inside the end of the fixing rod 5 away from the collection head 1. A slot 12 is provided on the side wall of the collection head 1 for the slot 12. The slot 12 is an L-shaped structure. A limiting slot 13 is provided on the side wall of the fixing rod 5 near the slot 12. The slot 12 is communicated with the limiting slot 13. The edge of the slot 12 near the limiting slot 13 is rotatably connected to an anti-return baffle 17 through a torsion spring. The top of the anti-return baffle 17 is fixedly connected to a soft block 18, and the top side wall of the slot 12 opposite to the soft block 18 is fixedly connected to a blocking block 19.

[0021] The technical effect of this solution is as follows: because the auxiliary protrusion 10 is fixed on the inner wall of the collecting head 1, and the collecting head 1 is designed to be a conical structure, the collected soil will gradually be sheathed in the collecting head 1 when the collecting head 1 is gradually inserted into the soil layer. As the internal space of the collecting head 1 shrinks, pressure will gradually be applied to the collected sample, thereby ensuring that the sample is stably in the collecting head 1. Then, the collecting head 1 is rotated, and as the collecting head 1 rotates, the auxiliary protrusion 10 will be stuck in the sample, thereby improving the stability of the sample in the collecting head 1. At the same time, as the cutting line 11 rotates, the connection between the sample and the soil layer will be cut, thereby avoiding the soil layer pulling the sample during the lifting process, causing the sample to fall off, and improving the stability of the sample after collection.

[0022] The side wall of the connecting rod 6 near one end of the fixed rod 5 is fixedly connected to an expansion plate 15, and the side wall position of the connecting rod 6 near the expansion plate 15 and opposite to the slot 12 is fixedly connected to an insert block 14, and the insert block 14 passes through the slot 12 and is inserted into the limiting groove 13.

The expansion plate 15 is inserted into the slot 12 of the fixed rod 5, and the outer wall of the expansion plate 15 is evenly fixedly connected with an anti-slip rubber pad 16, which fits tightly with the inner wall of the slot 12. The end of the connecting rod 6 away from the fixed rod 5 has the same structure as the top end of the fixed rod 5, and the end of the connecting rod 6 away from the fixed rod 5 is detachably connected to the control column 7. The connection method of the control column 7 to the connecting rod 6 is the same as that of the fixed rod 5 and the connecting rod 6. The side walls on both sides of the control column 7 away from one end of the connecting rod 6 are fixedly connected with handles 8.

[0023] The technical effect of this solution is: when the length needs to be increased, the expansion plate 15 is inserted into the slot 12, and the insert block 14 is inserted into the slot 12 at the same time, and then the connecting rod 6 is rotated to drive the insert block 14 to move in the slot 12. During the movement, the anti-return baffle 17 will be pushed open, so that the insert block 14 can be smoothly moved into the limiting groove 13, completing the assembly connection of the connecting rod 6 and the fixed rod 5. When disassembling, it is only necessary to rotate the connecting rod 6 in the opposite direction to move the insert block 14 out of the limiting groove 13 and the slot 12, thereby improving the convenience of disassembly and assembly and the stability during use.
