Description

Technical Field

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

[0002] When detecting agricultural products, it is necessary to randomly collect samples before they can be used for detection.

[0003] Although the existing sampling devices for agricultural product detection can shear and collect agricultural products, most of them are used for agricultural products at relatively close distances. However, to ensure the randomness of samples, it is often necessary to collect samples at relatively high heights or in relatively complex environments. The existing collection devices are not competent, and the existing sampling devices do not have a transmission component. After the agricultural products are sheared and collected, they need to be held by hand to prevent damage. Summary of the Utility Model

[0008] Further, a sliding ring is connected in the sleeve, both the sliding ring and one end of the sleeve are connected with sliding holes, and the sliding holes are slidably matched with the inner rod. Sliding between two points is convenient to ensure that the inner rod can move stably under the drive of the driving component, so that the movable knife and the fixed knife can cooperate for shearing.

[0009] Further, a connecting seat is connected between the inner rod and the end wall of the sleeve and the sliding ring, and a spring is connected between the connecting seat and the end wall of the sleeve. The spring is sleeved outside the inner rod. Through the cooperation of the connecting seat and the spring, it is convenient to make the movable knife reset after the shearing operation is completed and the driving component is released, so that a gap is reserved between the movable knife and the fixed knife, which is convenient for shearing agricultural products.

[0010] Further, the driving component includes a first through hole connected to the sleeve and a second through hole connected to the inner rod. A connecting shaft is connected in the first through hole, and a driving rod is hinged on the connecting shaft. One end of the driving rod passes through the second through hole, and the other end is connected with a driving handle. By pulling the driving handle, the driving handle drives the driving rod to rotate around the connecting shaft. Due to the through-fit of the driving rod and the second through hole, the driving rod slides.

[0011] Further, the transmission component includes connecting frames at both ends. A tension spring is connected between the opposite connecting frames. A flexible tube is connected to the connecting frames outside the tension spring. The top connecting frame is connected to the fixed frame, and a plurality of fastening buttons are circumferentially hinged to the bottom connecting frame. The cooperation of the connecting frames, the tension spring, the flexible tube, and the fastening buttons facilitates the stretching and contraction of the flexible tube, and further facilitates the guiding of the transmission of agricultural products. The setting of the fastening buttons facilitates the positioning of the flexible tube after contraction or stretching, which is convenient for storage or for supporting the flexible tube.

[0012] Further, the fixed frame and the connecting frame are concentrically arranged. The fixed frame is of a U-shaped structure. A limiting rod is connected to the free end of one end of the fixed knife on the fixed frame. The setting of the fixed frame facilitates the support of the fixed knife and the transmission component, and the setting of the limiting rod facilitates the limitation of the root during the sliding of the root between the movable knife and the fixed knife during the shearing process.

[0013] Further, a support rod is hinged in the middle of the sleeve, and the other end of the support rod is connected with a support leg. The setting of the support rod and the support leg facilitates the support of the sleeve when the sleeve is suddenly stressed after the agricultural product is sheared off and falls.
