Description

Technical Field

[0001] The utility model relates to the technical field of biochemical engineering, in particular to a biochemical engineering soil sampling device. Background Art

[0002] Biochemical soil sampling refers to the process of collecting soil samples for biochemical soil analysis. Through biochemical soil sampling and analysis, researchers can understand the biological, chemical and physical properties of the soil, help guide soil management, improve soil quality, promote plant growth, reduce soil pollution, and protect the ecological environment. Soil sampling requires the use of a soil sampling device.

[0003] The current soil sampling device is mainly composed of a rod body and a sampling tube. During operation, the sampling tube is inserted into the soil through the rod body to collect soil samples. The judgment of the sampling amount in this sampling process depends entirely on visual observation. Once the sampling tube is filled with soil, if it continues to be pressed down, the soil sample will be over-compacted, which will have a significant impact on the density and pore structure of the sample soil. At the same time, it may significantly change the soil's water permeability, gas exchange capacity, and microbial activity and other key properties, thereby greatly affecting the analysis results of the soil sample. Therefore, a biochemical soil sampling device is proposed. Utility Model Content

[0026] Reference Figure 1-Figure 4 , is an embodiment of the utility model, and provides a biochemical soil sampling device, which includes:

[0027] The main body 100 includes a tube body 101, a connecting tube 102 is fixedly connected to the bottom of the tube body 101, a sampling tube 103 is detachably connected to the bottom of the connecting tube 102, and two groups of cross bars 104 are fixedly connected to the top of the side wall of the tube body 101, and the two groups of cross bars 104 are vertically arranged with the tube body 101, and the axes of the two groups of cross bars 104 coincide with each other;

[0028] The indicating mechanism 200 includes an indicating rod 201, which passes through the tube body 101. A bottom plate 202 is arranged in the sampling tube 103, and the bottom plate 202 is fixedly connected to the bottom end of the indicating rod 201. The top of the indicating rod 201 is fixedly connected to the limiting block 203. A push tube 204 is fixedly connected to the top of the bottom plate 202, and the push tube 204 is sleeved on the outside of the indicating rod 201. A limiting ring 205 is fixedly sleeved on the inside of the connecting tube 102. A slip ring 206 is also arranged in the connecting tube 102. The slip ring 206 is slidably sleeved on the outside of the indicating rod 201 and its bottom abuts against the limiting ring 205. A spring 207 is arranged above the slip ring 206. The spring 207 is sleeved on the outside of the indicating rod 201 and its two ends abut against the connecting tube 102 and the slip ring 206 respectively.

[0029] Among them, scale lines are set on the outside of the indicator rod 201. When the bottom of the bottom plate 202 is flush with the bottom of the sampling tube 103, the top of the tube body 101 is aligned with the zero scale of the scale line. A red indicator bar is also set on the outside of the indicator rod 201. The indicator bar is located directly below the scale lines. The top of the push tube 204 and the bottom of the slip ring 206 are in contact with the top of the tube body 101 and are aligned with the top of the indicator bar.

[0030] In addition, the axes of the tube body 101, the connecting tube 102 and the sampling tube 103 are arranged to overlap, which is beneficial to improving the structural stability of the device. The bottom of the sampling tube 103 is serrated, which is convenient for cutting the soil. The main body 100 also includes an anti-slip sleeve 105. There are two groups of anti-slip sleeves 105. The two groups of anti-slip sleeves 105 are respectively fixed on the outside of the two groups of cross bars 104. The anti-slip sleeves 105 are used to avoid slipping during use.

[0031] In addition, both sets of anti-slip covers 105 are made of rubber material, which has strong elasticity and is conducive to improving the grip feel. Both sets of anti-slip covers 105 are provided with anti-slip grooves on the outside to further improve the anti-slip performance.

[0032] It should be noted that an external thread is provided at the bottom of the side wall of the connecting tube 102, and an internal thread is provided at the top of the side wall of the sampling tube 103 and is threadedly connected to the connecting tube 102. The connecting tube 102 and the sampling tube 103 are detachably connected through threaded cooperation. The thread rotation direction of the connecting tube 102 is clockwise, and a clockwise rotation indicator arrow is engraved on the top of the connecting tube 102 to prevent the sampling personnel from rotating counterclockwise during sampling, which may cause the connecting tube 102 to separate from the sampling tube 103.

[0033] Working principle: The thread of the connecting tube 102 is rotated clockwise, and the sampling tube 103 is tightened with the connecting tube 102 clockwise. When sampling, the device is rotated clockwise through two sets of cross bars 104 and pressure is applied to the device downward. The serrations at the bottom of the sampling tube 103 cut and separate the soil. The device is gradually pressed into the soil, and the soil enters the sampling tube 103. The bottom plate 202 moves up, driving the indicator rod 201 to move up. The sampling amount can be judged by observing the scale of the indicator rod 201 facing the top of the tube body 101. When the push tube 204 abuts the slip ring 206, the device is continued to be pressed down. The indicator bar of the indicator rod 201 gradually extends out of the tube body 101. At this time, stop pressing the device, shake the device appropriately, separate the sample in the sampling tube 103 from the soil, and pull out the device to complete the sampling.

[0034] The sampling tube 103 can be removed by rotating it counterclockwise, so as to facilitate taking out samples and cleaning the device.

[0035] It should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the spirit and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
