Description

Technical Field

[0001] This utility model relates to the field of soil sample drying technology, specifically a portable soil sample drying and testing device. Background Technology

[0002] Soil is a loose layer of material on the Earth's surface, composed of various granular minerals, organic matter, water, air, microorganisms, etc., and is capable of supporting plant growth. Soil consists of minerals formed from the weathering of rocks, organic matter produced by the decomposition of plant and animal remains and microbial remains, soil organisms (solid phase), water (liquid phase), air (gaseous phase), and oxidized humus.

[0003] Soil pollution testing requires samples to be pre-dried. The current standard procedure involves collecting soil samples on-site, returning them to the laboratory, and drying them using large drying equipment before testing. This method cannot achieve rapid on-site testing, resulting in long testing cycles and difficulty in meeting real-time requirements. Existing laboratory drying equipment is generally bulky and cumbersome, lacking portability and cannot be deployed to the sampling site. During the drying process, moist soil easily clumps together into dense clumps. The clump structure severely hinders heat transfer and moisture evaporation, requiring a significantly longer drying time to achieve the target dryness, and the drying effect is uneven.

[0004] The purpose of this invention is to provide a portable soil sample drying and testing device to solve the problems mentioned in the background art. Utility Model Content

[0032] The rotating shaft 4 is symmetrically installed on the outside of the housing 1 with the housing 1 as the center reference. The handle 5 and the rotating shaft 4 are connected to each other. The top of the handle 5 is fixedly opened with a fixing port. The sealing cover 6 is threadedly connected to the housing 1 through the fixing ring 7.

[0033] There are four openings 16, and the openings 16 are fan-shaped. The mounting port 20 is symmetrically installed inside the housing 1 with the housing 1 as the center reference. The placement plate 14 is connected to the connecting port 13 on the rotor 12 through the connecting port 15. The guide plate 21 is an inclined structure.

[0034] In this embodiment, the storage tray 22 is placed on the placement plate 14 inside the housing 1. The interlocking plate 26 installed in the center of the storage tray 22 and the square connecting block 27 at the lower end are precisely interlocked with the square connecting port 13 at the bottom of the housing 1. The weighed soil sample is placed into the assembled storage tray 22.

The guide plates 21 guide and disperse the hot airflow, so that it flows quickly and evenly inside the housing 1. The evenly distributed hot airflow dries the soil sample in the storage tray 22 quickly and efficiently.

[0035] Example 2:

[0036] Please see Figure 5 This embodiment provides a technical solution based on Embodiment 1:

[0037] Storage tray 22 is installed on the upper end of placement plate 14.
