[0011] Figure 1 The structure of the utility model is shown Figure 1 ;

[0012] Figure 2 The structure of the utility model is shown Figure 2 ;

[0013] Figure 3 A schematic diagram of the internal structure of the sampler is shown. DETAILED DESCRIPTION

[0014] In order to more clearly understand the above-mentioned purpose, features and advantages of the utility model, the utility model is further described in detail below in conjunction with the accompanying drawings and specific implementation methods. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0015] like Figure 1~Figure 3 A dairy product sampling and testing device shown in the figure includes a detector 1 and a sampling device. The detector 1 is a self-cleaning detector 1. The self-cleaning detector 1 mainly enables it to automatically clean the dairy products that have been completely tested. A cleaning joint 2 is provided on one side of the detector 1. The cleaning joint 2 is connected to an external cleaning liquid pump through a water pipe. A discharge joint 3 is provided on the other side. One end of the discharge pipe is connected to the discharge joint 3 and the other end is connected to the processing box. The display control panel 4 of the detector 1 is located on the rear side of the detector 1, which is convenient for the tester to observe and set parameters.

[0016] The sampling device is composed of a support rod 5, a slide rail 6, a walking cylinder 7, a lifting cylinder 8, and a sampler 9. The detector 1 is installed on the base, the support rod 5 is fixed on the base, and two slide rails 6 are fixed in parallel to the upper end of the support rod 5. A slide plate 17 is provided on the slide rail 6, and a vertical lifting cylinder 8 is provided on the slide plate 17. The front section of the lifting cylinder 8 serves as a push-pull rod 801 of the sampler 9 (for the convenience of description, the front section of the lifting cylinder 8 is described as the push-pull rod 801) and a plunger 13 is provided at the front section of the lifting cylinder 8. A baffle 14 is provided at the rear end of the sampler 9. The push-pull rod 801 passes through the opening in the center of the baffle 14. A snap ring 15 is provided at the front of the push-pull rod 801. The snap ring The outer diameter of 15 is larger than the diameter of the opening. As the push-pull rod 801 continues to rise until the retaining ring 15 presses against the baffle 14, the sampler 9 will be driven to rise. In order to ensure the normal lifting and lowering of the sampler 9, the friction between the slide bar 10 and the adjustment plate 16 and the slide plate 17 is much greater than the friction between the plunger 13 and the sampler 9; two symmetrical slide bars 10 are provided at the end of the sampler 9, and the upper ends of the slide bars 10 slide through the slide plate 17, and the lower end of the sampler 9 is provided with a sampling head 11; a horizontal fixing frame 12 is provided between the slide rails 6, and the rear section of the traveling cylinder 7 is fixed to the middle of the fixing frame 12 and is parallel to the slide rail 6, and the front section of the traveling cylinder 7 is fixed to the middle of the slide plate 17.

[0017] The detection process of this device is:

[0018] The sampling head 11 is detachably mounted on the lower end of the sampler 9. You can select a suitable sampling head 11 and tighten it on the lower end of the sampler 9, then set the sampling interval time and sampling area and other parameters, start the detector 1 and the control system of the entire device. After the device is started, the travel cylinder 7 will push the slide plate 17 forward along the slide rail 6 to the sampling area, and then the lifting cylinder 8 will descend. When the push-pull rod 801 is against the lower end of the sampler 9, it will drive the sampler 9 to descend as a whole until the sampling head 11 arrives at the sampling area for sampling, that is, extracting dairy products. During the extraction process, due to the large friction between the slide bar 10 and the slide plate 17, the sampler 9 will not move upward, so that the sampling can be completed. After the sampling is completed, the lifting cylinder 8 drives the plunger 1 3 pulls back. With the pull back of the lifting cylinder 8, the clamping ring 15 on the push-pull rod 801 reaches the baffle 14, thereby driving the sampler 9 to rise. Then the walking cylinder 7 drives the slide plate 17 to move toward the detector 1. After the movement is completed, the sampling head 11 will face the docking port 18 at the top of the detector 1. Finally, the lifting cylinder 8 pushes the sample in the sampler 9 from the docking port 18 into the detector 1 for detection. After the detection is completed, the sample is discharged from the discharge joint 3 and cleaned with cleaning fluid for the next detection.

[0019] In order to facilitate the adjustment of the lateral position of the sampler 9, a slot 19 is provided in the middle of the slide plate 17, an adjustment plate 16 is installed on the upper side of the slot 19, the rear section of the lifting cylinder 8 is fixed in the middle of the adjustment plate 16, and the slide rod 10 also passes through the adjustment plate 16.

[0020] The above description is only the preferred embodiment of the utility model, and is not intended to limit the utility model. For those skilled in the art, the utility model can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
