Description

Technical Field

[0001] The utility model belongs to the technical field of wheat moisture content detection, in particular to a sampling device for wheat moisture content detection. Background Art

[0002] The moisture content of wheat is generally between 13% and 14%. It is particularly important to test the moisture content of wheat because the moisture content directly affects the storage, processing and quality safety of wheat. Understanding the moisture content of wheat can help determine appropriate storage conditions.

[0003] Before testing the moisture content of wheat, a sampling device is needed to be inserted into the pile of wheat to take samples, and then the samples are sent to the testing instrument for testing. However, some sampling devices have a multi-porous interconnected structure, that is, only one wheat pile can be sampled in one sampling work. In order to improve the efficiency of sampling work, a sampling device for detecting the moisture content of wheat is designed. The device samples the wheat pile through an arc-surface storage trough, and the wide surface tube and the narrow surface tube are used separately, so that multiple wheat piles can be sampled. Different wheat piles can be sampled separately in one sampling work, which can improve the efficiency of sampling work. Utility Model Content

Example

[0026] Figure 1-6The present invention shows a sampling device for detecting moisture content of wheat according to an embodiment of the utility model, which comprises: a straight rod 1: a plurality of rectangular grooves 2 are provided on the surface of the straight rod 1, a straight hole 3 is provided in the inner cavity of the straight rod 1, a curved material storage groove 4 is slidably connected to the inner cavity of the rectangular groove 2, an expansion sheet 5 is fixedly connected to the inner wall of the straight hole 3, a spring 6 is welded between the curved material storage groove 4 and the expansion sheet 5, a wide surface tube 7 is rotatably connected to the surface of the straight rod 1, a narrow surface tube 8 is rotatably connected to the surface of the straight rod 1, an annular groove 12 is provided on the surface of the straight rod 1, and a wide surface tube 8 is rotatably connected to the surface of the straight rod 1. The inner walls of the noodle tube 7 and the narrow noodle tube 8 are fixedly connected with a limiting ring 13, and the surface of the limiting ring 13 is rotatably connected to the inner cavity of the annular groove 12. Through the coordinated use of the annular groove 12 and the limiting ring 13, the positions of the wide noodle tube 7 and the narrow noodle tube 8 can be limited when the wide noodle tube 7 or the narrow noodle tube 8 is rotated, which can prevent the wide noodle tube 7 or the narrow noodle tube 8 from sliding on the surface of the straight rod 1. A conical head 14 is welded to the bottom end of the straight rod 1, and handles 15 are fixedly connected to the left and right sides of the top of the straight rod 1.

[0027] Working principle: When the utility model is used, the user rotates the wide tube 7 on the surface of the straight rod 1. When the position of the rectangular hole 9 is aligned with the position of the rectangular groove 2, the arc surface storage groove 4 is pushed to slide to the outside of the rectangular groove 2 under the elastic force of the spring 6, and then the straight rod 1 is pushed toward the direction of the wheat pile. Under the action of the conical head 14, the straight rod 1 and the arc surface storage groove 4 are inserted into the interior of the wheat pile until the wheat grains fill the inner cavity of the arc surface storage groove 4, and then the wide tube 7 is rotated again. At this time, under the action of the arc surface of the rectangular hole 9 and the arc surface of the arc surface storage groove 4, the arc surface storage groove 4 is pushed to slide in the inner cavity of the rectangular groove 2 until the position of the rectangular hole 9 is misaligned with the position of the rectangular groove 2, so that the arc surface storage groove 4 and the wheat grains are stored in the inner cavity of the rectangular groove 2, and then the wide tube 7 is moved to another wheat pile to rotate the narrow tube 8, and the above work is repeated, so that different wheat piles can be sampled separately in one sampling work, which can improve the efficiency of the sampling work.

[0028] In summary, the sampling device for detecting the moisture content of wheat rotates the wide tube 7 or the narrow tube 8 on the surface of the straight rod 1. At this time, under the elastic force of the spring 6, the arc surface storage trough 4 slides to the outside of the rectangular groove 2, and the wheat pile is sampled, so that different wheat piles can be sampled separately in one sampling work, thereby improving the efficiency of the sampling work.
