[0004] However, there are some problems with the existing technology: the traditional device directly places the test object into the detection body for detection, and the test object needs to be pretreated before detection. When detecting pesticide residues in eggs, the eggshell needs to be peeled off and the pesticide residues in the egg white and egg yolk need to be detected. The traditional detection device does not have this function, so we propose an ultrasonic extraction device for pesticide residues in eggs. Utility Model Content

[0005] In view of the problems existing in the prior art, the utility model provides an ultrasonic extraction device for pesticide residues in eggs, which solves the problem that traditional devices directly place the detection object into a detection body for detection, and the object to be detected needs to be pre-treated before detection. When detecting pesticide residues in eggs, it is necessary to peel off the eggshell and detect pesticide residues in egg white and egg yolk, and traditional detection devices do not have this function.

[0006] The utility model is implemented as follows: an ultrasonic extraction device for pesticide residues in eggs comprises an ultrasonic extractor for detecting pesticide residues, wherein the input end of the ultrasonic extractor is connected to a pretreatment component via a transmission tube, wherein the pretreatment component comprises a treatment tube, wherein a cylindrical channel is provided inside the treatment tube, wherein a motor is fixedly mounted on the input end of the treatment tube, wherein a gradient auger is rotatably mounted inside the treatment tube, wherein the output end of the motor is connected to the gradient auger, and the gradient auger is driven by the motor to transmit and squeeze the egg action.

The motor is closely connected to the gradient auger, which is the core transmission mechanism in the processing tube. The design of the gradient auger is particularly unique, and the spacing on the side away from the motor gradually decreases.

In this process, due to the change in the spacing of the gradient auger, the eggs are subjected to a gradually increasing extrusion force, and the eggshell is finally broken. This design not only ensures the smooth transmission of the eggs, but also realizes the automatic breaking of the eggshell, greatly simplifying the operation process. The eggs after pretreatment are accurately sent to the ultrasonic extractor through the transmission tube. Under the action of ultrasound, the pesticide residues in the eggs are quickly and effectively extracted, providing reliable samples for subsequent detection and analysis.

[0019] In order to further understand the content, features and effects of the utility model, the following embodiments are given as examples and described in detail with reference to the accompanying drawings.

[0020] The structure of the utility model is described in detail below in conjunction with the accompanying drawings.

[0021] like Figures 1 to 3As shown, the ultrasonic extraction device for pesticide residues in eggs provided by the embodiment of the utility model includes an ultrasonic extractor 3 for detecting pesticide residues. The input end of the ultrasonic extractor 3 is connected to a pretreatment component 6 through a transmission tube 5. The pretreatment component 6 includes a treatment tube 602. A cylindrical channel is opened inside the treatment tube 602. A motor 601 is fixedly installed at the input end of the treatment tube 602. A gradient auger 604 is rotatably installed inside the treatment tube 602. The output end of the motor 601 is connected to the gradient auger 604. The gradient auger 604 is driven by the motor 601 to transmit and squeeze the egg action.

[0022] In the ultrasonic extraction device for pesticide residues in eggs, a cylindrical channel is designed inside the processing tube 602 to ensure the stability of the eggs during the transmission process. A motor 601 is fixedly installed at one end of the processing tube 602 to provide power for the entire pretreatment process. The motor 601 is closely connected to the gradient auger 604, which is the core transmission mechanism in the processing tube 602. The design of the gradient auger 604 is particularly unique, and the spacing on the side away from the motor 601 gradually decreases. When the motor 601 is started, the gradient auger 604 starts to rotate, and the eggs are gradually transferred to the depth of the processing tube 602. In this process, due to the change in the spacing of the gradient auger 604, the eggs are subjected to a gradually increasing extrusion force, and the eggshell is finally broken. This design not only ensures the smooth transmission of the eggs, but also realizes the automatic breaking of the eggshell, greatly simplifying the operation process. The eggs after pretreatment are accurately sent to the ultrasonic extractor 3 through the transmission tube 5. Under the action of ultrasound, the pesticide residues in the eggs are quickly and effectively extracted, providing a reliable sample for subsequent detection and analysis. In actual use, the operator only needs to place the eggs on one side of the processing tube 602 and start the motor 601, and the entire pretreatment and extraction process will be automatically carried out. This not only improves the detection efficiency, but also reduces the difficulty of operation, making the detection of pesticide residues in eggs more convenient and accurate.

[0023] In this embodiment, the bottom of the ultrasonic extractor 3 is fixedly connected to the bottom plate 1, a support frame 2 is fixedly installed on one side of the bottom plate 1, a shunt seat 4 is fixedly installed on the top of the support frame 2, and the input end of the shunt seat 4 is fixedly connected to the transmission pipe 5. A plurality of feed pipes 7 are fixedly connected to the bottom of the shunt seat 4, and the plurality of feed pipes 7 are arranged corresponding to the test tube placement slots of the ultrasonic extractor 3, and the plurality of feed pipes 7 are connected to the transmission pipe 5 through the shunt seat 4.

[0024] A base plate 1 is firmly connected to the bottom of the ultrasonic extractor 3, which not only plays a supporting role, but also ensures the stable operation of the entire device. A support frame 2 is installed on one side of the base plate 1. The support frame 2 has a solid structure and is responsible for carrying the important diverter seat 4. The diverter seat 4 is located at the upper part of the support frame 2, and the input end of the diverter seat 4 is tightly fixed to the transmission tube 5 to ensure that the sample can smoothly enter the diverter seat 4. The lower part of the diverter seat 4 is connected to a plurality of feed pipes 7, which are not only numerous, but also precisely correspond to the test tube placement slot of the ultrasonic extractor 3. Each feed pipe 7 can accurately introduce the sample into the corresponding test tube, thereby realizing multi-test tube detection of the same sample. Multiple feed pipes 7 are connected to the transmission tube 5 through the diverter seat 4 to form a complete sample transmission system. After the sample is pretreated, it enters the diverter seat 4 through the transmission tube 5, and then the diverter seat 4 evenly distributes the sample to each feed pipe 7, and finally enters the test tube of the ultrasonic extractor 3 for detection. This improves the detection efficiency. More importantly, by using multiple test tubes to test the same sample, more data samples can be obtained, further improving the accuracy and reliability of the data.

[0025] In this embodiment, the motor 601 and the processing tube 602 are fixedly installed on one side of the upper part of the bottom plate 1, and an egg liquid collection box 605 and an egg shell collection box 607 are plugged and installed between the bottom plate 1 and the processing tube 602. A delivery port 603 for placing eggs is provided on the side of the processing tube 602 close to the motor 601, and two discharge ports 609 are opened and closed at the lower part of the side of the processing tube 602 away from the motor 601. A sieve plate 608 is fixedly installed at one of the discharge ports 609 close to the motor 601, and the sieve plate 608 is aligned with the center of the egg liquid collection box 605, and the other discharge port 609 is aligned with the center of the egg shell collection box 607. An inclined slot is provided inside the egg liquid collection box 605, and a micro liquid pump 606 is fixedly installed at the lower part of the egg liquid collection box 605, and the input end of the micro liquid pump 606 is connected with the inclined slot, and the output end of the micro liquid pump 606 is fixedly connected to the transmission tube 5.

[0026] The motor 601 and the processing tube 602 are firmly fixed on one side of the upper part of the bottom plate 1. Between the bottom plate 1 and the processing tube 602, an egg liquid collection box 605 and an egg shell collection box 607 are cleverly plugged and installed to facilitate subsequent cleaning and collection work. A delivery port 603 is opened on the side of the processing tube 602 close to the motor 601 for placing the eggs to be processed. When the motor 601 is started, the gradient auger 604 starts to rotate, and the eggs are transferred from the delivery port 603 to the depth of the processing tube 602. As the eggs gradually go deeper, the spacing of the gradient auger 604 gradually decreases, exerting an increasing squeezing force on the eggs until the eggshell is broken. When the eggshell is broken, the egg white and the egg yolk flow out through the discharge port 609 close to the motor 601, and a sieve plate 608 is fixedly installed at the discharge port 609. The design of the sieve plate 608 allows the eggshell fragments to be intercepted, while the egg white and the egg yolk pass smoothly and fall directly into the egg liquid collection box 605 below. Since the egg liquid collection box 605 is provided with an inclined slot inside, the egg liquid can be quickly gathered to a lower position along the inclined slot, which is convenient for the extraction of the micro-liquid pump 606. When the micro-liquid pump 606 is started, the egg liquid is quickly extracted from the inclined slot, and the egg liquid is transported to the ultrasonic extractor 3 through the transmission tube 5 fixed at its output end for subsequent pesticide residue detection. At the same time, the eggshell fragments flow out through another feed opening 609, which is aligned with the center of the eggshell collection box 607 to ensure that the eggshell can fall into the eggshell collection box 607 accurately. In this way, egg white and eggshell are effectively separated, which provides convenience for subsequent processing and detection. The whole process realizes automated operation, which not only improves work efficiency, but also ensures the separation effect of egg white and eggshell, and provides high-quality samples for subsequent pesticide residue detection.

[0027] The working principle of this utility model:

[0028] When in use, the cylindrical channel designed inside the processing tube 602 ensures the stability of the eggs during transmission. The motor 601 drives the gradual auger 604 to rotate, and the spacing of the auger away from the motor 601 gradually decreases, gradually increasing the squeezing force on the eggs to achieve automatic breaking of the eggshell. The broken eggs are sent to the ultrasonic extractor 3 through the transmission tube 5. Under the action of ultrasound, the pesticide residues in the eggs are quickly extracted. The entire pretreatment and extraction process is automated, and the operator only needs to place the eggs and start the motor 601. This design simplifies the operation process, improves the detection efficiency, reduces the difficulty of operation, makes the detection of pesticide residues in eggs more convenient and accurate, and provides technical support for food safety testing. When the motor 601 is started, the gradual auger 604 starts to rotate, and the eggs are transferred from the delivery port 603 to the depth of the processing tube 602. As the eggs gradually go deeper, the spacing of the gradual auger 604 gradually decreases, exerting more and more squeezing force on the eggs until the eggshell is broken. When the eggshell is broken, the egg white and the yolk flow out through the feed opening 609 near the motor 601, and the sieve plate 608 is fixedly installed at the feed opening 609. The design of the sieve plate 608 allows the eggshell fragments to be intercepted, while the egg white and the yolk pass smoothly and fall directly into the egg liquid collection box 605 below. Since the egg liquid collection box 605 is provided with an inclined slot inside, the egg liquid can be quickly gathered to a lower position along the inclined slot, which is convenient for the extraction of the micro liquid pump 606. When the micro liquid pump 606 is started, the egg liquid is quickly extracted from the inclined slot, and the egg liquid is transported to the ultrasonic extractor 3 through the transmission pipe 5 fixed at its output end for subsequent pesticide residue detection. At the same time, the eggshell fragments flow out through another feed opening 609, which is aligned with the center of the egg shell collection box 607 to ensure that the eggshell can fall into the egg shell collection box 607 accurately. In this way, the egg white and the eggshell are effectively separated, which provides convenience for subsequent processing and detection. The entire process is automated, which not only improves work efficiency but also ensures the separation of egg white and eggshell, providing high-quality samples for subsequent pesticide residue testing.
