Description

Technical Field

[0001] The utility model relates to the technical field of drug detection, in particular to an oscillating structure for pesticide residue detection. Background Art

[0002] Pesticides are chemical agents used to control pests and weeds in agricultural production. They can be divided into different types such as insecticides, fungicides, herbicides and plant growth regulators. The use of pesticides can help farmers increase the yield and quality of crops and reduce the damage to crops caused by pests and weeds. However, there are also some problems with the use of pesticides. First, excessive or improper use of pesticides may cause excessive crop residues and cause harm to human health. Secondly, the use of pesticides may also pollute the environment, have a negative impact on the ecosystem, and destroy biodiversity.

[0003] Excessive pesticide residues in agricultural products affect the food safety and health of consumers. In severe cases, they may cause poisoning or even endanger the lives of consumers. Therefore, countries around the world attach great importance to the problem of pesticide residues. When detecting pesticide residues, the pesticides need to be extracted and then shaken. The existing shaking device can only shake a single or multiple test tubes, and the test tubes are fixed by test tube clamps, and other containers cannot be used for shaking. Utility Model Content

[0004] The utility model discloses an oscillating structure for pesticide residue detection, aiming to solve the technical problem that the existing oscillating device can only oscillate a single or multiple test tubes, fix the test tubes by test tube clamps, and cannot oscillate other containers.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0007] The assembly mechanism comprises an oscillation box, the top of which is provided with evenly distributed placement grooves, the bottom of which is provided with a chassis, the circumferential inner wall of the placement groove is rotatably connected with a connecting rod, one end of which is fixedly connected with a clamping rod, the circumferential outer wall of the clamping rod is fixedly connected with a first spring near the middle part, one end of which is fixedly connected to the inner wall of the placement groove;

[0008] Limiting mechanism, used to fix a single sample.

[0009] In this solution, a single or multiple containers can be fixed by the assembly mechanism and the limiting mechanism. After the collection tube is placed in the placement groove, the bottom of the collection tube contacts the chassis, and the circumferential outer wall of the collection tube presses the clamping rod downward to stretch the first spring. Under the elastic force of the first spring, the clamping rod fixes the circumferential outer wall of the collection tube. It can be suitable for collection tubes of different diameters. While preventing the collection tube from tipping over, the collection tube has a certain amount of space for movement, which improves the vibration effect. The conical bottle is installed on the limiting mechanism, and the container can be fixed separately. Multiple limiting mechanisms are set, and vibration detection can be performed at the same time, saving vibration time and improving work efficiency.

[0010] In a preferred solution, the limiting mechanism includes a base plate, a vertical rod is fixed to the circumferential outer wall of the base plate, a fixing block is sleeved on the circumferential outer wall of the vertical rod, a threaded hole is opened on one side of the fixing block, an adjusting rod is rotatably connected in the threaded hole, one end of the adjusting rod is fixedly connected to a limiting ring, the circumferential outer wall of the vertical rod is located above the fixing block and is sleeved on a third spring, the circumferential outer wall of the vertical rod is located above the third spring and is rotatably connected to a fixing ring via a thread, a rubber pad is provided on the top of the base plate, and the conical flask is placed above the rubber pad.

[0011] By adopting the above scheme, the conical flask is placed on the bottom plate, the limiting ring is set at the bottle mouth of the conical flask, the fixing ring is rotated to move downward, and the third spring is compressed, so that the fixing block cooperates with the magnetic plate and the limiting ring to press the conical flask downward, so that the conical flask is stably placed on the bottom plate, and the pressure of the limiting ring on the conical flask is adjusted by the third spring to avoid the conical flask being broken due to excessive pressure during vibration, which is conducive to the safe implementation of the vibration work.

[0012] As can be seen from the above, an oscillating structure for pesticide residue detection includes a collection tube, a conical bottle, a base and an oscillating plate arranged above the base, and also includes:

[0013] The assembly mechanism comprises an oscillation box, the top of which is provided with evenly distributed placement grooves, the bottom of which is provided with a chassis, the circumferential inner wall of the placement groove is rotatably connected with a connecting rod, one end of which is fixedly connected with a clamping rod, the circumferential outer wall of the clamping rod is fixedly connected with a first spring near the middle part, one end of which is fixedly connected to the inner wall of the placement groove;

[0014] The limiting mechanism is used to fix a single sample. The utility model provides an oscillating structure for pesticide residue detection, which is suitable for collection tubes of different diameters to prevent the collection tubes from tipping over. The conical flask is installed on the limiting mechanism, which can fix the container separately. Multiple limiting mechanisms are set, and oscillation detection can be performed at the same time, saving oscillation time and improving work efficiency. BRIEF DESCRIPTION OF THE DRAWINGS
