Description

Technical Field

[0001] This utility model belongs to the field of soil testing technology, specifically relating to a soil drying device for soil testing. Background Technology

[0002] Soil testing is essentially the same as water and air quality testing. By employing appropriate testing methods, various physicochemical properties of the soil are measured, including iron, manganese, total potassium, organic matter, total nitrogen, available phosphorus, total phosphorus, moisture, total arsenic, available boron, fluoride, chloride, mineral oil, and total salt content. This achieves purposes such as monitoring the current state of soil quality; detecting soil pollution incidents; dynamically monitoring land remediation of pollutants; and investigating soil background values. When inspecting certain aspects of the soil, dry soil is required, thus necessitating soil drying equipment.

[0003] Currently, the conventional method for drying soil samples is to place them in a cool environment for natural air drying. Although this method is simple, it has significant drawbacks such as being time-consuming and inefficient. It usually takes several days or even weeks to reach the required drying standards for experiments, which seriously restricts the overall efficiency of soil testing and makes it difficult to meet the needs of modern laboratories for rapid acquisition of test results. The problem that this device addresses is how to significantly accelerate the soil drying speed and thus improve processing efficiency. Utility Model Content

The second screw 20 is spirally connected to the fixed base plate 3. The protective net 2 can be detached and installed through the fixing plate 19 and the second screw 20. A blower is installed inside the protective net 2. An exhaust port 10 is fixedly installed at the output end of the blower. The blower can effectively accelerate the airflow inside the chamber. A first movable shaft 18 is movably installed at the front of the drying chamber 1. An outer chamber door 4 is fixedly installed on the surface of the first movable shaft 18. An inner door 5 is installed on the left side of the outer door 4. Sealing rubber 11 is installed on both sides of the inner door 5. A display screen 7 is fixedly installed on the left side of the drying oven 1. A temperature sensor 8 is fixedly installed on the right side of the display screen 7, and the display screen 7 is electrically connected to the temperature sensor 8. The temperature sensor 8 monitors the temperature inside the oven through physical contact. The first movable shaft 18 allows the outer door 4 to open, close, and rotate. The outer door 4, together with the inner door 5 and the sealing rubber 11, forms a double-layer elastic sealing layer, which can block external moisture intrusion and internal heat dissipation in both directions when closed. A handle 13 is installed on the right side of the outer door 4. First screws 12 are screwed onto both sides of the handle 13 and are screwed to the outer door 4. The handle 13 is used for convenient opening and closing of the outer door. Door 4 and air vents are provided on both sides of the drying chamber 1. A fixed frame 16 is fixedly installed inside the air vents. A first protective shell 22 is fixedly installed inside the fixed frame 16. A first motor is fixedly installed inside the first protective shell 22. An exhaust fan 17 is fixedly installed on the first motor through a drive shaft at the output end. The first motor drives the exhaust fan 17 to forcibly draw in moisture, forming a directional airflow circulation with the bottom blower, thereby increasing the speed of moisture discharge. A receiving plate 9 is fixedly installed on the inner wall of the drying chamber 1. A limiting plate 6 is installed on the upper surface of the receiving plate 9 to fix the placement box 14. Ventilation mesh 15 is installed on both sides of the receiving plate 9. The placement box 14 is movably installed on the top of the receiving plate 9.

The second motor drives the first movable wheel 28.The conveyor belt 27 drives the metal comb 25 to periodically scrape and comb, forcibly breaking up soil clumps and turning over deep, wet soil. The heating element is embedded and fixed inside the metal receiving plate 9, achieving full heat diffusion through heat conduction. The sealing plate 24, riveted by rivets 23, completely seals the maintenance port of the heating element, preventing the intrusion of moisture and soil particles, thus avoiding the risk of electrode corrosion and short circuits. All electrical equipment in this device is powered by an external power source.

[0023] In one aspect of this embodiment, the protective net 2 is fixed to the fixed base plate 3 by the fixing piece 19 and the second screw 20, thereby achieving detachable installation. At the same time, the protective net can ensure that the blower exhaust port 10 will not be blocked. While facilitating the cleaning of accumulated soil particles, it can maintain airflow stability. The inner box door 5 and the sealing rubber 11 form a double-layer sealing structure, which can isolate most of the moisture intrusion when closed, thereby ensuring the internal environment of the drying box 1 and preventing the samples from being moistened again.

[0024] In one aspect of this embodiment, a first screw 12, spirally connected to the outer door 4, can fix a handle 13, which makes it more convenient and quick to open or close the door. A display screen 7 is fixedly installed on the left side of the drying chamber 1, and a temperature sensor 8 is fixedly installed on the right side of the display screen 7.
