Description

Technical Field

[0001] The utility model relates to the technical field of detection equipment, in particular to a detection equipment for soil pesticide residue detection. Background Technique

[0002] Pesticide residue refers to the phenomenon that after pesticides are applied in agricultural production, a part of the pesticides directly or indirectly remain in grains, vegetables, fruits, livestock products, aquatic products, as well as in soil and water bodies.

[0003] After long-term cultivation of the soil, it is necessary to detect the pesticide residues in the soil, and the internal pesticides in the soil are compared and detected through a detection device.

[0004] However, before the existing detection device detects the pesticides in the soil, it is necessary to add a variety of different solvents to the soil sample and then shake it. The existing detection device cannot automatically add reagents to the sample, thus reducing the work efficiency of the staff.

[0005] Moreover, when the existing detection equipment detects the sample in the test tube, it is necessary for the staff to manually move the test tube into the detection port on the detection equipment. During the manual movement process, it is easy to cause the reagent to pour, resulting in the need to reconfigure, which is troublesome and cumbersome. Summary of the Invention

[0006] The purpose of the utility model is to provide a detection equipment for soil pesticide residue detection to solve the problems raised in the above background technique.

[0044] In use, first place the soil sample inside the test tube 7, then move the test tube 7 into the inside of the bottom plate 4. Open the cylinder 9, and the cylinder 9 drives the top plate 5 to move downward. The movement of the top plate 5 drives the pressing rod 10 and the syringe 6 to move downward. The pressing rod 10 pushes the baffle 11 on the test tube 7 downward, and the baffle 11 rotates and opens through the rotating column 14.

Open the second telescopic motor 23, and the second telescopic motor 23 drives the telescopic column 24 to move upward. The movement of the telescopic column 24 drives the test tube 7 to move out of the inside of the bottom plate 4 through the feeding block 22. Control the threaded column 18 to rotate in the reverse direction to drive the test tube 7 on the feeding block 22 to move above the detection port 2.
