Description

Technical Field

[0001] The utility model relates to the field of detection assistance, in particular to a detection reagent extraction auxiliary device. Background Art

[0002] Detection reagent extraction is a commonly used separation and enrichment technology for extracting target compounds from complex samples. Compared with the extraction steps of liquid samples, the extraction steps for solid samples are more cumbersome. The operator needs to perform a preliminary crushing process on the solid sample so that the solid sample can be refined, thereby facilitating the sample to enter the test tube for extraction reaction with the reagent. However, the preliminary crushing process does not pursue refinement, so the crushed solid sample will still have particles of different sizes. In the process of feeding the solid sample into the test tube, it is easy to cause blockage or incomplete reaction with the reagent, affecting the extraction efficiency and the final effect. In addition, in the process of feeding, the existing operation relies on the operator to manually feed the material, and the level of automation is low. The operator needs to observe the feed amount at all times, which will increase the operator's workload in the repeated process.

[0003] Therefore, in order to solve the above problems, a detection reagent extraction auxiliary device is now developed which can perform automatic intermittent feeding and perform secondary crushing and dispersion treatment during the feeding process. Utility Model Content

[0004] In order to overcome the shortcomings of the existing devices, which require operators to continuously add samples into the equipment during the specific operation process, and the sample adding process is generally manually controlled, with low accuracy in controlling the feed amount, and it is difficult for operators to immediately check the internal situation and determine whether to continue adding materials, the utility model provides a detection reagent extraction auxiliary device that can perform automatic intermittent feeding and perform secondary crushing and dispersion processing during the feeding process.

[0005] The technical solution of the utility model is as follows: a detection reagent extraction auxiliary device, including a feeding chamber, a first mounting frame is connected to the right side of the upper portion of the feeding chamber, a second mounting frame is connected to the right side of the lower portion of the feeding chamber, a first driving motor is installed in the second mounting frame, a rotating shaft is connected to the output shaft of the first driving motor, the rotating shaft is rotatably connected to the second mounting frame, the upper end of the rotating shaft is located inside the second mounting frame, crushing rings are rotatably connected to the upper and lower sides of the feeding chamber, gears are connected to the crushing rings, the upper ends of the rotating shaft and the output shaft of the first driving motor are also connected to the gears, the adjacent gears are meshed with each other, and a feeding mechanism for intermittent feeding processing is provided at the upper portion of the feeding chamber.

[0006] Optionally, the unloading mechanism includes a third mounting frame, the third mounting frame is mounted on the top of the second mounting frame, the second driving motor is mounted inside the third mounting frame, a unloading piece is connected to the output shaft of the second driving motor, and the left side of the unloading piece passes through the unloading cavity.

[0007] Optionally, an anti-blocking mechanism is further included, and the anti-blocking mechanism includes a mounting ring. The mounting ring is rotatably arranged on the top of the feeding chamber, and a material removing rod is connected to the inner side of the mounting ring.

[0008] Optionally, the diameters of the openings at the upper and lower ends of the material discharge cavity are larger than the diameter of the internal channel.

[0009] Optionally, a material holding groove is provided in the middle of each of the material discharging parts.

[0010] Optionally, a manual control handle is connected to the left end of the blanking piece.

[0011] By adopting the above technical solution, the beneficial effects of the utility model are:

[0012] 1. The utility model controls the automatic rotation of the unloading part through the output shaft of the second driving motor to achieve the effect of intermittent automatic unloading, avoiding pouring too much sample raw material at one time, resulting in the crushing ring being unable to efficiently crush and scatter and causing sample blockage. At the same time, during the unloading process, the operator can use the manual control handle to finely control the unloading part according to the unloading situation of the sample to improve the accuracy of the operation. After the sample enters the unloading chamber, the sample is crushed and scattered for the second time, making the sample more scattered and small, which is convenient for subsequent efficient extraction operations.

[0013] 2. When the sample raw materials are fed through the upper side of the feeding chamber, in order to avoid the sample accumulation and blocking at the feeding port, the mounting ring can be rotated after the sample is blocked so that the material pusher can push and guide the sample so that the sample can normally enter the feeding chamber for pre-treatment.

DETAILED DESCRIPTION

[0018] The following description is only a preferred embodiment of the present invention and does not limit the protection scope of the present invention.

[0019] Example 1

[0020] A detection reagent extraction auxiliary device, such as Figure 1 and Figure 2 As shown, it includes a feeding chamber 1, the opening diameters of the upper and lower ends of the feeding chamber 1 are larger than the diameter of the internal channel, a first mounting frame 2 is connected to the upper right side of the feeding chamber 1, a second mounting frame 3 is connected to the lower right side of the feeding chamber 1, a first driving motor 7 is installed in the second mounting frame 3, the output shaft of the first driving motor 7 is arranged upward, a rotating shaft 6 is connected to the output shaft of the first driving motor 7, the rotating shaft 6 is rotatably connected to the second mounting frame 3, the upper end of the rotating shaft 6 is located inside the second mounting frame 3, the upper and lower sides of the feeding chamber 1 are rotatably connected to the crushing ring 4, the crushing ring 4 is connected to the gear 5, the upper end of the rotating shaft 6 and the output shaft of the first driving motor 7 are also connected to the gear 5, the adjacent gears 5 are meshed with each other, and a feeding mechanism 8 for intermittent feeding processing is provided at the upper part of the feeding chamber 1.

[0021] like Figure 1 and Figure 3 As shown, the unloading mechanism 8 includes a third mounting frame 81, which is mounted on the top of the second mounting frame 3. A second driving motor 82 is installed inside the third mounting frame 81. The output shaft of the second driving motor 82 is set to the left. A unloading piece 83 is connected to the output shaft of the second driving motor 82. The left side of the unloading piece 83 passes through the unloading cavity 1. A material holding groove is opened in the middle of the unloading piece 83, and a manual control handle is connected to the left end of the unloading piece 83.

[0022] It should be noted that when performing detection reagent extraction, the sample needs to be processed and fed, and the sample is placed through the upper opening of the feeding chamber 1 so that the raw material enters along the inner wall of the feeding chamber 1. At this time, the second drive motor 82 is selected and controlled according to the sample feeding situation, and the feeding piece 83 is driven to rotate by the output shaft of the second drive motor 82, so that the sample at the upper opening position of the feeding chamber 1 can be intermittently fed. When feeding is no longer needed, the second drive motor 82 is turned off. It should be noted that due to the electric rotation characteristics, it is often difficult for operators to accurately control the sealing of the upper opening of the feeding chamber 1. When it is found that the sample still has a feeding situation, the feeding piece 83 can be completely blocked by rotating the manual control handle. After the sample enters the feeding chamber 1, the first drive motor 7 is started. The rotation of the output shaft of the first drive motor 7 will drive the rotating shaft 6 to rotate, so that the gear 5 drives the crushing ring 4 to rotate, and the sample entering the feeding chamber 1 is crushed and scattered for the second time to avoid sample accumulation and blockage. At the same time, the scattered sample can also improve the subsequent extraction efficiency.

[0023] Example 2

[0024] On the basis of Example 1, Figure 1 and Figure 3 As shown, it also includes an anti-blocking mechanism 9, which includes a mounting ring 91. The mounting ring 91 is rotatably arranged on the top of the feeding chamber 1, and a material moving rod 92 for moving and guiding the sample is connected to the inner side of the mounting ring 91.

[0025] It should be noted that when the sample raw material is fed through the upper side of the feed chamber 1, in order to avoid sample accumulation and blockage at the feed port, the mounting ring 91 can be rotated after the sample is blocked so that the feed rod 92 pushes and guides the sample, so that the sample can normally enter the feed chamber 1 for pre-processing.

[0026] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit the protection scope of the utility model. Although the utility model is described in detail with reference to the preferred embodiments, ordinary technicians in this field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the essence and scope of the technical solution of the utility model.
