Description

Technical Field

[0001] This utility model relates to the technical field of grain warehouse monitoring equipment, and more specifically, to a sampling device for grain warehouse monitoring. Background Technology

[0002] In the field of grain storage, ensuring the quality and safety of grain within granaries is of paramount importance. Regular monitoring of grain within granaries is a crucial step in guaranteeing grain quality, and accurate sampling is the foundation of this monitoring work. However, existing grain granary sampling methods have several shortcomings. Traditional sampling methods often fail to obtain representative samples, failing to accurately reflect the grain condition at different depths and locations within the granary. Some sampling devices are complex to operate and inefficient, increasing the time and labor costs of monitoring. Other devices cannot simultaneously perform multi-depth, stratified sampling of grain and monitoring of granary environmental parameters. These problems not only affect the accuracy and reliability of monitoring results but also create difficulties for the scientific management of granaries and the assurance of grain quality.

[0021] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0022] like Figures 1-5 The sampling device shown is used for monitoring grain warehouses. The device includes a main cylinder 1 and a sampling cylinder 2. The main cylinder 1 is inserted into the grain in the grain warehouse. Its lower end is a cone to facilitate insertion into the grain pile. The upper outer support plate 3 is used to support and fix the main cylinder 1. The inner wall of the main cylinder 1 is provided with a vertical slot 5. A vertical plate 4 is slidably installed in the slot 5. The vertical plate 4 is in close contact with the slot 5, which can effectively prevent grain from entering the slot 5 and affecting the operation of the device. The inner wall of the slot 5 is provided with evenly spaced outer openings 14 for grain to enter.

[0023] The sampling cylinder 2 is slidably inserted into the main cylinder 1. Its side wall is provided with an inner inlet 6 that corresponds one-to-one with the outer opening 14 and is in the same horizontal position. The vertical plate 4 is provided with multiple through ports 7, which correspond one-to-one with the outer opening 14, but their cross-sectional dimensions are smaller than the cross-sectional dimensions of the outer opening 14 and the inner inlet 6. The through ports 7 are also staggered from the outer opening 14 and the inner inlet 6. This design allows the outer opening 14, through ports 7, and inner inlet 6 to form a channel after the sampling cylinder 2 is inserted into the main cylinder 1. Grain can enter the layered sampling chamber to achieve layered quantitative sampling. The sampling cylinder 2 is provided with multiple horizontal plates 8. Each inner inlet 6 has a horizontal plate 8 at its bottom. The horizontal plates 8 divide the inside of the sampling cylinder 2 into multiple sampling chambers, which facilitates separate sampling and monitoring of grain at different depths.

[0024] As a further improvement, a temperature sensor and a humidity sensor are installed on the outer wall of the main cylinder 1, which can monitor the temperature and humidity in the grain silo in real time and provide more reference data for grain storage. The temperature sensor and humidity sensor are installed inside the sensor housing 9. The sensor housing 9 has smooth rounded corners to reduce obstruction to grain flow. The left and right sides of the sensor housing 9 have arrayed small holes to ensure the normal operation of the sensor.

[0025] As a further improvement, the inner surface of the vertical plate 4 is an arc-shaped surface, which matches the curvature of the inner wall of the main cylinder 1, ensuring the smooth sliding and sealing of the vertical plate 4 inside the main cylinder 1.

[0026] As a further improvement, a baffle 10 is provided on the top of the outside of the opening 7 on the vertical plate 4. The baffle 10 is located above the lower side of the outer opening 14. The baffle 10 is arranged horizontally. When the vertical plate 4 is lifted, the baffle 10 can be used as a limit for lifting the vertical plate 4 to avoid lifting too much and causing the opening 7 to be misaligned with the outer opening 14.

[0027] As a further improvement, multiple slots 5 are provided, and the slots 5 are symmetrical. Each slot 5 has an evenly spaced outer opening 14 and a vertical plate 4. The inner wall of the sampling tube 2 has multiple rows of inner inlets 6. The inner openings and outer openings 14 correspond one-to-one, which improves the efficiency and accuracy of sampling.

[0028] As a further improvement, the upper ends of multiple vertical plates 4 are all connected and fixed with a lifting ring 11 to facilitate the sliding of the vertical plates 4.

[0029] As a further improvement, the inner wall of the main cylinder 1 is provided with two centrally symmetrical vertical grooves 12, which are parallel to the slot 5. The outer wall of the sampling cylinder 2 is provided with vertical ribs 13 corresponding to the vertical grooves 12. After the vertical ribs 13 are aligned with the vertical grooves 12, the sampling cylinder 2 is vertically inserted into the main cylinder 1. When inserted, the inner opening 6 is vertically aligned with the outer opening 14 and the through opening 7.

[0030] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
