Description

Technical Field

[0001] The utility model relates to the technical field of sampling equipment, in particular to a directional sampling and detection device for agricultural products. Background Art

[0002] It's well known that when purchasing agricultural products, especially granular agricultural products (such as soybeans, rice, corn kernels, and wheat), or after a period of storage, sampling and testing of the agricultural products is necessary to intuitively judge the quality of the batch. Traditional agricultural product sampling methods typically include random sampling or quantitative sampling, but these methods may not be able to obtain accurate and comprehensive samples when dealing with granular agricultural products.

[0003] Especially when sampling stacked agricultural products, the varying depths of the produce can lead to variations in sampling depth, potentially affecting the accuracy of test results. Furthermore, traditional sampling equipment often cannot accurately select the sampling depth, potentially sampling agricultural products at non-target depths, thus affecting sampling accuracy.

[0004] A search of the publication number CN221100143U discloses a directional sampling and testing device for agricultural products. Through the design of the blocking block, the device can accurately sample agricultural products at a target depth while ignoring agricultural products at other depths, thereby improving the accuracy and efficiency of sampling. The block is driven by an electric push rod.

[0005] The above patent has shortcomings when used. The above patent inserts the detection equipment into the crops. Since the force-bearing area of ​​the block is large, the block is driven to move by the electric push rod. When collecting agricultural products with higher density (such as corn kernels), the block is not easy to open, resulting in low collection efficiency and even easy damage to the electric push rod. Utility Model Content

[0006] (1) Technical problems solved

[0007] In view of the deficiencies in the prior art, the present invention provides a directional sampling and detection device for agricultural products, which can effectively improve the collection efficiency of crops and enhance practicality.

[0008] (2) Technical solution

[0010] Furthermore, the blocking assembly includes a polygonal pin arranged on the driving rod, and a slot arranged on the collecting cylinder and matching with the pin.

[0011] Furthermore, the blocking assembly includes a shift rod provided on the driving rod, and a stopper provided on the collecting cylinder and matching with the shift rod.

[0012] Furthermore, a first limiting ring is fixedly provided on the inner wall of the insertion tube, a fixing block is provided on the outer wall of the driving rod, and a spring is provided between the first limiting ring and the fixing block.

[0013] In addition, the inner diameter of the first limiting ring matches the outer diameter of the driving rod.

[0015] In addition, a first handle is provided on the insertion tube.

[0016] In addition, a second handle is provided on the driving rod.

[0017] (3) Beneficial effects

[0018] Compared with the existing technology, the present invention provides a directional sampling and testing device for agricultural products, which has the following beneficial effects:

[0019] 1. This agricultural product directional sampling and testing equipment uses a driving rod and a collecting barrel. When the insertion tube is inserted into place, the driving rod is used to drive the collecting barrel to rotate. At this time, the collecting barrel does not need to overcome the resistance of the crops to the collecting barrel, thereby facilitating the rotation of the collecting barrel. After the first opening and the second opening overlap, the crops enter the storage chamber, facilitating the collection of crops and improving the collection efficiency of crops.

[0020] 2. This agricultural product directional sampling and detection equipment is separated by a driving rod and a collecting cylinder. When the driving rod drives the collecting cylinder to rotate, causing the first opening and the second opening to overlap, the driving rod can hit the collecting cylinder, and the vibration force generated by the impact can be used to accelerate the speed at which crops enter the storage chamber, thereby improving practicality.
