Abstract
Description
Technical Field
[0001] This utility model relates to the field of soil environmental testing technology, specifically to a sample screening device for soil environmental testing. Background Technology
[0002] Soil environmental monitoring is crucial in agriculture, environmental protection, and land management. To assess soil quality and health, and to analyze its particle composition and the levels of various pollutants, soil samples typically undergo sieving. Sieving soil particles of different sizes helps researchers better understand the physical and chemical properties of the soil, providing reliable basic data for subsequent analysis and research.
[0003] Traditional soil sieving methods mostly rely on manual operation or simple manual sieves. While these methods are relatively simple, they have several drawbacks in practical applications. First, manual sieving is not only time-consuming and labor-intensive, but also prone to uneven operation, leading to poor sieving results and an inability to accurately separate soil particles of different sizes. Second, traditional sieves are prone to clogging when processing wet soil, clay, or other soil samples with high moisture content, resulting in reduced sieving efficiency and potentially damaging the equipment. Furthermore, existing soil sieving devices generally lack multi-stage sieving designs, failing to efficiently separate soil particles of different sizes.
[0004] With the increasing demands for soil quality monitoring, traditional screening methods can no longer meet the requirements for accuracy and efficiency.
[0005] Therefore, based on the above-mentioned technical problems, it is necessary for those skilled in the art to develop a sample screening device for soil environmental testing. Utility Model Content

[0024] The features and exemplary embodiments of various aspects of this utility model will now be described in detail. To make the objectives, technical solutions, and advantages of this utility model clearer, the following description, in conjunction with the accompanying drawings and specific embodiments, will provide a further detailed description. For those skilled in the art, this utility model can be implemented without some of these specific details. The following description of the embodiments is merely intended to provide a better understanding of this utility model by illustrating examples.
[0025] like Figure 1 , Figure 2 and Figure 3 As shown, this utility model provides a technical solution for a sample sieving device for soil environmental testing: it includes a sieving box 1, the top of which is provided with a frame 11, and a box cover 12 is provided inside the frame 11. The box cover 12 is provided with a feeding port 121. The two sides of the sieving box 1 are provided with fixed upright plates 21 and reinforcing plates 22, and the upright plates 21 and reinforcing plates 22 are vertically connected to form a support structure.
[0026] like Figure 2 and Figure 3 As shown, the screening box 1 is equipped with at least two layers of inclined inverted V-shaped screens, including an inverted V-shaped screen 31 and an inverted V-shaped screen 32 distributed from top to bottom. The aperture of the inverted V-shaped screen 31 is larger than that of the inverted V-shaped screen 32. The inclination angle of the inverted V-shaped screen 31 and the inverted V-shaped screen 32 is 15°-30°, and they are arranged parallel and spaced apart. The bottom edge of the inverted V-shaped screen 31 is aligned with the feed inlet baffle 13, and the bottom edge of the inverted V-shaped screen 32 is aligned with the feed inlet baffle 14.
[0027] In addition, such as Figure 1 As shown, the screening box 1 is provided with multiple discharge ports, including a discharge port baffle 13, a discharge port baffle 2 14 and a discharge port 3 15 located on the side wall of the screening box, which correspond to the inverted V-shaped screen 1 31, the inverted V-shaped screen 2 32 and the discharge channel at the bottom of the screening box, respectively.
[0028] The vibrator 23 is fixed to the side wall of the vertical plate 21 and connected to the screening box 1. The vibrator 23 is a variable frequency motor with a frequency adjustment range of 20-60Hz, and is fixed to the central area of the vertical plate 21 by bolts.
[0029] The inverted V-shaped screen 1 (31) and the inverted V-shaped screen 2 (32) are detachably installed on the inner wall of the screening box 1 via snap fasteners, making them easy to clean and maintain.
[0030] When the soil environmental testing sample sieving device of this utility model is working, the soil sample to be sieved is first put into the sieving box 1 through the feeding port 121. The vibrator 23 is started, and the vibration generated by the vibrator 23 is transmitted to the sieving box 1 through the vertical plate 21, causing the inverted V-shaped screen 31 and the inverted V-shaped screen 32 to vibrate. Under the action of vibration, the soil sample is sieved through the sieve holes, and soil particles of different sizes fall into the corresponding discharge port baffles 13 and 14 and the discharge port 15, thereby realizing multi-stage sieving.
[0031] Due to the inclined design of the inverted V-shaped screen 31 and the inverted V-shaped screen 32, soil samples can pass smoothly through the screens during the screening process, effectively avoiding screen clogging. Meanwhile, the detachable design of the inverted V-shaped screens 31 and 32 makes cleaning and maintenance simple and convenient, further extending the service life of the screening device.
[0032] This utility model discloses a soil environmental testing sample sieving device. By setting an inverted V-shaped multi-stage sieve structure and a vibrator, it achieves efficient and accurate sieving of soil samples. It has the advantages of simple operation, high sieving efficiency and high accuracy, and is suitable for various soil environmental testing scenarios, providing strong technical support for soil quality monitoring.
