In the soil testing process, it is necessary to use a dryer to remove free water and hygroscopic water from the soil to avoid the interference of moisture on the determination of nutrient content and make the test results more accurate.

[0003] A search revealed an existing technology (publication number: N213811433U) for a soil sample drying device. The document describes a device that "includes a soil dryer body, with a fixed frame on the inner wall of the dryer body, a fixed plate on the top of the frame, a screw inserted into the fixed plate, a clamping block on one side of the screw, a soil placement box on the inner wall of the clamping block, and the clamping blocks symmetrically distributed about the bisector of the soil placement box. A pressure plate is also provided on the inner wall of the dryer body, and a downward pressure cylinder is located on the top of the dryer body and connected to the pressure plate." However, during the drying process, the soil composition can cause a pungent odor, which can be uncomfortable for testing personnel if inhaled. Therefore, designing a land natural resource engineering testing device is essential. Utility Model Content

[0004] The purpose of this invention is to provide a land natural resource engineering testing device that solves the problem in related technologies that the device is affected by soil composition during use, and produces a pungent odor during drying, which can cause discomfort if inhaled by the testing personnel.

An electric heating wire 17 is installed inside the heating trough 15 and is connected to the power supply 16. A controller 18 is screwed onto the outer wall of the drying chamber 1. The power supply 16 supplies power to the electric heating wire 17, which can generate heat energy. The power of the heating wire 17 can be adjusted using the controller 18. A pair of brackets 19 are screwed onto the inner walls of both sides of the drying chamber 1, and the drying rack 2 is inserted into each of the two pairs of brackets 19 on both sides. A threaded rod 20 is threaded onto the top of each bracket 19, and an anti-slip pad 21 is fitted onto the bottom of the threaded rod 20. The bottom of the anti-slip pad 21 fits against the top end face of the drying rack 2. The brackets 19 can support and fix the drying rack 2. Rotating the threaded rod 20 can lower the anti-slip pad 21 and press it to fix the drying rack 2. Several mounting holes 22 are evenly spaced on the top end face of the drying rack 2, and a drying frame 23 is inserted into the mounting hole 22. A base 24 is welded to the bottom of the drying frame 23. The drying frame 23 and the base 24 can restrict soil moisture.

The drained moisture can be collected using the collection box 5. By closing the chamber door 29 and using the controller 18 to start the heating wire 17, and powering the heating wire 17 with the power supply 16, the heating wire 17 can generate heat energy, thereby increasing the temperature inside the drying chamber 1. Outside air can be transported to the exhaust hood 25 through the air intake fan 27 and the connecting pipe 28, and then exhausted through the air outlet 26. The force generated by the airflow can make the heat evenly distributed. Simultaneously, the outside air can be used to regulate the temperature inside the drying chamber 1. The exhaust fan 8 can remove the odor produced during soil drying. The activated carbon in the deodorizing box 7 can perform preliminary filtration. The gas is discharged into the filter box 9 through the exhaust fan 8. The flow valve 13 is activated to make the air freshener in the storage tank 12 drip onto the sponge 11. The gas passes through the sponge 11 and neutralizes with the air freshener, which can reduce the pungent odor. The treated gas will be discharged from the exhaust pipe 10. After drying, the drying frame 23 can be removed from the installation port 22 by lifting the base 24, making it easy to obtain the dried soil. The composition of the dried soil can be detected by the soil tester 30. The drying box 1 can be moved by pushing the push rod 31 under the action of the universal wheels 32, making it convenient to carry when going out. The heat insulation plate 34 in the heat insulation tank 33 can play a heat preservation role to prevent heat loss. The anti-slip pad 21 can be separated from the drying rack 2 by turning the threaded rod 20, making it easy to remove the drying rack 2.
