Description

Technical Field

[0001] The present invention relates to the technical field of soil detection, and more particularly to a soil quick-drying device for soil detection. Background Art

[0002] Soil monitoring is basically consistent with water quality and air monitoring. By adopting appropriate measurement methods to measure various physical and chemical properties of the soil, such as iron, manganese, total potassium, organic matter, total nitrogen, available phosphorus, total phosphorus, moisture, total arsenic, available boron, fluoride, chloride, mineral oil and total salt, the current status of soil quality can be monitored.

[0003] At present, the soil used for soil testing needs to be dried and then crushed. After the soil is crushed, the soil is screened and finally the screened soil is collected and tested. However, the temperature generated during the drying process will cause the nitrate nitrogen in the soil to decompose, thereby reducing the nitrate nitrogen content in the soil, and further reducing the accuracy of soil testing. Although some testing institutions do not use drying equipment to dry the nitrate nitrogen in the soil, but place the soil in a cool place for shade drying, the time required for the soil to be dried in the shade is relatively long. If the soil is dried in the shade for too long, the nitrate nitrogen content in the soil will also be reduced, thereby reducing the accuracy of soil testing. Summary of the invention

[0023] Specifically, by starting the first drive motor 901, the sealing plate 903 will be driven to move toward the sealing chamber 8. When the sealing plate 903 coincides with the sealing chamber 8, the first bevel gear 907 will be driven to rotate one hundred and eighty degrees, thereby driving the second bevel gear 403 to rotate, and then driving the air-drying plate 401 and the second gear 404 to rotate.

[0027] Working principle: first, the soil to be air-dried is placed on the air-drying plate 401 through the feed port 2, and then the fan 6 is started to draw the natural wind from the outside to air-dry the soil in the air-drying chamber 3. When the soil has been air-dried, the first drive motor 901 is started to drive the threaded rod 902 to rotate, thereby driving the sealing plate 903 to move along the threaded rod 902 toward one end of the sealing chamber 8 until the sealing plate 903 coincides with the sealing chamber 8. In the process of moving, the sealing plate 903 will drive the first rack 904 to move toward the sealing chamber 8, thereby driving the first gear 905 to rotate during the movement of the first rack 904, and then driving the first rotating belt 906 to rotate. As the first rotating belt 906 rotates, the first bevel gear 907 will be driven to rotate, thereby driving the second bevel gear 403 to rotate, and then driving the rotating rod 402 to rotate. The rotation of the rotating rod 402 will drive the air-drying plate 401 to rotate, thereby driving the second gear 404 to rotate, and then driving the second rack 405 to move upward along the second gear 404. When the sealing plate 903 coincides with the sealing chamber 8, it will drive the first bevel gear 907 to rotate 180 degrees, thereby driving the second bevel gear 403 to rotate 180 degrees, and then driving the air-drying plate 401 to rotate 180 degrees. During the rotation of the air-drying plate 401, the air-dried soil will fall into the inner cavity of the grinding chamber 1105. As the air-drying plate 401 rotates 180 degrees, the second rack 405 will coincide with the trigger groove provided at the lower end of the controller 10, starting the second drive motor 1101 and driving the circular rotating rod 1102 to rotate, thereby driving the crushing rod 1103 and the grinding plate 1104 to rotate, thereby crushing and grinding the soil, and the ground soil will be transported to the feed through the filter hole 1106. The soil in the rectangular receiving cavity 1202 increases, and the return spring 1204 is driven to contract, thereby driving the rectangular support plate 1203, the circular trigger block 1205 and the rectangular receiving cavity 1202 to move downward along the second slide slot until the circular trigger block 1205 coincides with the circular hole opened on the upper end surface of the second controller 1206. At this time, the second controller 1206 will turn off the rotation of the second drive motor 1101, and the rectangular receiving cavity 1202 is filled with air-dried soil for soil detection. Then, the handles connected to the two end surfaces of the rectangular receiving cavity 1202 are used to take out the air-dried soil and perform soil detection operations, and all operations are ended.
