Description

Technical Field

[0001] The invention relates to the technical field of vegetable sampling, in particular to a sampling device used for vegetable resource investigation. Background Art

[0002] As the demand for vegetable variety identification, genetic analysis, and resource assessment increases, the need for efficient acquisition of vegetable samples is becoming increasingly urgent.

[0003] Referring to a Chinese patent, a vegetable sample detection sampling device (Announcement No.: CN213209511U, Announcement Date: 2021-05-14) solves the problem that the existing vegetable sample sampling device only takes samples from one part at a time, and the sample is directly exposed to the outside, which requires multiple samplings, and the water content of the sample is easily lost, increasing the error of the detection. However, this patent still has the following shortcomings:

[0004] (1) When sampling vegetables, the sampling position is fixed, and there is no automatic flipping device to automatically flip the vegetables to achieve the purpose of switching sampling at different parts. In other words, it is not possible to perform multi-angle and multi-point sampling at the same time. The samples after sampling are relatively single, which affects the accuracy of the test data;

[0005] (2) After sampling, the vegetables are prone to leaking juice and residue, which will pollute the working environment. The juice and residue need to be manually wiped away, which increases the workload of the staff;

[0043] Example 3

[0044] This embodiment is obtained by combining Example 1 and Example 2. Figure 1-Figure 7As shown, when working, pull the two pull rings 48, so that the pull rings 48 drive the pull rod 45 and the arc plate 46 to move upward, further place the vegetables between the two vegetable placement rings 44, use the two vegetable placement rings 44 to support the vegetables, further loosen the two pull rings 48, and use the reset elasticity of the spring 47 and the arc plate 46 to clamp the vegetables on the vegetable placement rings 44. When the length of the vegetables is longer or shorter, by pulling the two pull rings 76, the vertical rod 72 slides out of the slot, and further slide the horizontal rod 42 left and right to adjust the length to the appropriate After the length is reached, the pull ring 2 76 is loosened, and the vertical rod 72 is further reset and inserted into the slot 73, so that the horizontal position of the two vegetable placement rings 44 can be adjusted to meet the needs of vegetables of different lengths.

The sampling steps are further repeated. While the motor 2 410 drives the right side horizontal tube 41 to rotate, the rotation of the pulley 3 51 and the pulley 4 54 further drives the driving rod 53 to rotate. At the same time, the driving rod 53 drives the bevel gear 1 56, the bevel gear 2 58 and the threaded rod 57 to rotate.
