Description

Technical Field

[0001] This invention relates to the field of sampling equipment technology, specifically to a sampling device for detecting wolfberry with multiple divisions and its usage method. Background Technology

[0002] Goji berries are harvested in summer and autumn when the fruit is ripe. After removing the stems, they are placed in a cool place to dry until the skin wrinkles, and then sun-dried until the outer skin is hard and the flesh is soft. In the process of agricultural industrialization, the production of agricultural products such as goji berries increasingly relies on exogenous substances such as pesticides, antibiotics and hormones. The amount of pesticides used in agricultural products remains high, and the unreasonable use of these substances will inevitably lead to excessive pesticide residues in agricultural products, affecting the safety of consumers. In severe cases, it can cause consumers to get sick, develop abnormally, or even directly cause poisoning and death. Therefore, it is necessary to sample and test goji berries and other agricultural products before putting them on the market.

[0003] However, in the existing technology, when preparing and testing samples, it is necessary to first weigh several equal portions of the goji berry sample on an electronic weighing device, then place the equal portions of the goji berry sample into each testing container, and finally inject the testing liquid into each testing container for processing. This process is quite complicated and increases the labor intensity of the staff. It is impossible to automatically divide the goji berry sample into several equal portions and add the testing liquid. Summary of the Invention

[0004] (a) Technical problems to be solved

[0005] The purpose of this invention is to provide a sampling device and method for detecting wolfberry that can be divided into multiple segments in order to solve the above-mentioned problems, thereby solving the problems of complicated sampling and segmentation process, repetitive work, and high labor intensity of workers.

[0006] (II) Technical Solution

[0007] To achieve the above objectives, the present invention provides the following technical solution:

[0008] This invention provides a sampling device for detecting wolfberry with multiple divisions, comprising a cylindrical sampling box. The sampling box has a detection liquid storage chamber and a sample division chamber arranged from bottom to top. The sample division chamber contains a division box structure for equally dividing the sample into several portions. Several sampling slots are evenly distributed at equal angles around the central axis on the outer wall of the sampling box near the sample division chamber. The number of sampling slots corresponds to the number of equal portions the sample is divided by the division box structure. Each sampling slot can be detachably fitted with a sampling box for collecting the sample after it has been equally divided by the division box structure. A detection liquid adding component is provided between the detection liquid storage chamber and the sampling slots for adding detection liquid to each sampling box. A PLC controller is located on the outer side of the sampling box.

[0009] Furthermore, the dividing box structure includes a sample dividing box body with a W-shaped axial cross-section. A vibration motor is installed on the top side of the middle part of the sample dividing box body. Several feeding slots are evenly distributed at equal angles around the central axis of the sample dividing box body on the inner bottom surface. Each feeding slot has a funnel at its lower opening that is wider at the top and narrower at the bottom. Dividing slots are provided on the side walls of the sample dividing box body between two feeding slots. Dividing plates are slidably installed in each dividing slot. The upper ends of these dividing plates that are close to each other are fixedly connected to each other by a connecting top plate. An electric telescopic rod is fixedly installed at the middle of the bottom surface of the sample dividing chamber. The push rod head of the electric telescopic rod is fixedly connected to the lower side of the connecting top plate. A sealing cover is installed directly above each feeding slot. The upper side of the sealing cover is a convex spherical surface. The two sides of the sealing cover are fixedly connected to the top side of the dividing plate by connecting ribs. A soft baffle plate is fixedly installed along the edge of the top side of the dividing plate. The output terminal of the PLC controller is electrically connected to the input terminal of the vibration motor.

[0010] Furthermore, when the push rod of the electric telescopic rod reaches its maximum stroke, the connecting top plate and the dividing plate move to the top side of the sample dividing box. At this time, the dividing plate divides the sample dividing box into several dividing chambers. The sealing cover separates from the discharge slot. Then, the connecting top plate drives the dividing plate to slide up and down in the dividing slot. When the push rod of the electric telescopic rod reaches its minimum stroke, the connecting top plate and the dividing plate move to the bottom side of the sample dividing box. At this time, the several dividing chambers in the sample dividing box form a connected whole, and the sealing cover seals the discharge slot.

[0011] Furthermore, a retaining edge is formed on the top outer edge of the sample dividing box, and four or more springs are fixedly connected to the lower side of the retaining edge, which are evenly distributed at equal angles with the central axis of the sample dividing box as the center. The upper edge of the sampling box is provided with a corresponding insertion hole for each spring. The depth of the insertion hole is smaller than the length of the spring. A box cover structure is provided on the upper side of the sample dividing box.

[0012] Furthermore, the detection liquid addition assembly includes a liquid pump fixedly installed on the bottom surface inside the detection liquid storage chamber. The outlet of the liquid pump is connected to one end of a liquid outlet pipe, and the other end of the liquid outlet pipe passes through the detection liquid storage chamber and is connected to an annular liquid passage pipe. The annular liquid passage pipe passes through the top of each sampling slot in sequence and is fixedly installed on the inner wall of the sample dividing chamber. A branch liquid guide pipe corresponding to each sampling slot is connected to the annular liquid passage pipe. A solenoid valve is installed on each branch liquid guide pipe. The output terminal of the PLC controller is electrically connected to the input terminal of the liquid pump and the solenoid valve respectively.

[0013] Furthermore, a liquid addition pipe is provided on the bottom surface of one of the sampling tanks. The bottom end of the liquid addition pipe is connected to the inside of the detection liquid storage chamber. A sealing cap is detachably provided on the upper end of the liquid addition pipe. A transparent observation plate is provided on the outer wall of the sampling box near the detection liquid storage chamber.

[0014] Furthermore, the sampling box is shaped like an elliptical cylinder with a hollow interior and an open top. A handle is fixedly installed on the outer wall of one end of the sampling box along its long axis. The handle is L-shaped. Each sampling slot is fixedly equipped with a baffle plate for placing and positioning the sampling box.

[0015] Furthermore, the lid structure includes a top cover, and the lower side of the top cover is fixedly provided with an insert edge that fits into the upper opening edge of the sample dividing box body. The top cover is made of transparent material, and a handle is fixedly provided on the upper side of the top cover.

[0016] A method of using a sampling device for detecting wolfberry with multiple fractions includes the following steps:

[0017] S1: Weigh a certain amount M of the wolfberry sample to be tested, open the box cover structure, and pour the wolfberry sample weighing M into the sample dividing box. At this time, the push rod of the electric telescopic rod of the dividing box structure is at its minimum stroke, and the sealing cover, dividing plate and connecting top plate are all at their lowest positions. At this time, the sealing cover seals the discharge hole groove.

[0018] S2 is controlled by a PLC controller to open the vibration motor located on the top side of the sample dividing box. The vibration motor vibrates, causing the sample dividing box to vibrate, thereby achieving uniform distribution of the wolfberry sample within the dividing box structure.

[0019] S3: The electric telescopic rod of the dividing box structure extends upward, thereby driving the sealing cover, dividing plate and connecting top plate to move upward. The dividing plate divides the sample goji berries into several equal portions. At this time, the sealing cover is separated from the feeding hole groove. The goji berry samples after equal division enter the sampling box in the sampling groove through the feeding hole groove and the funnel in sequence.

[0020] S4: The test liquid addition component adds the test liquid from the test liquid storage chamber into each sampling box. The PLC controller controls the opening of the liquid pump and solenoid valve. The liquid pump sequentially inputs the test liquid into the sampling box through the liquid outlet pipe, the annular liquid passage pipe and the branch liquid guide pipe. Finally, the sampling box is removed from the sampling tank.

[0021] (III) Beneficial Effects

[0022] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0023] 1. The dividing box structure can divide a certain amount of wolfberry sample weighed by an electronic weigher into several equal parts, and then the several equal parts of wolfberry sample can be dropped into each sampling box to realize automatic dividing and sampling of wolfberry.

[0024] 2. The vibration motor in the dividing box structure can play a dual role. The first role is to distribute the wolfberry sample evenly in the sample dividing box, which is convenient for subsequent equal division. The second role is to make the wolfberry sample fall out of the feeding hole groove under the vibration, so as to prevent the wolfberry sample from remaining in the sample dividing box.

[0025] 3. When adding test liquid to the goji berry samples that have been divided into each sampling box, the PLC controller controls the test liquid adding component to extract the test liquid storage chamber and inject it into each sampling box, avoiding the need for staff to repeatedly add test liquid to each sampling box one by one.

[0026] 4. Through the combination of the segmentation box structure and the detection liquid addition component, the automatic segmentation and sampling of wolfberry samples and the addition of detection liquid can be realized, making the repetitive detection and sampling work simpler and faster, simplifying the process, reducing the labor intensity of staff, and saving sampling and testing time.

[0033] To make the objectives, technical solutions, and advantages of this invention clearer, the technical solutions of this invention will be described in detail below. Obviously, the described embodiments are merely some embodiments of this invention, and not all embodiments. Based on the embodiments of this invention, all other implementation methods obtained by those skilled in the art without creative effort are within the scope of protection of this invention.

[0034] See Figure 1-4As shown, this invention provides a sampling device for goji berry testing with multiple divisions and its usage method. It includes a cylindrical sampling box 1. The sampling box 1 has a detection liquid storage chamber 10 and a sample division chamber, respectively, arranged from bottom to top. The sample division chamber has a division box structure 5 for equally dividing the sample into several portions. In the prior art, when preparing and testing a sample, several equal portions of the goji berry sample are first weighed on an electronic weighing device and then injected into the testing container. The division box structure 5, however, can quickly divide a certain amount of goji berries weighing M. The sample is divided into several equal portions, greatly saving the time of sample preparation. The sampling box 1 has several sampling slots 3 evenly distributed at equal angles around its central axis on the outer wall near the sample division chamber. The number of sampling slots 3 corresponds to the number of equal portions divided by the division box structure 5. Each sampling slot 3 can be detachably equipped with a sampling box 4 for collecting the sample after it has been divided by the division box structure 5. A detection liquid adding component 9 is installed between the detection liquid storage chamber 10 and the sampling slots 3 to add detection liquid to each sampling box 4. A PLC controller 2 is installed on the outside of the sampling box 1. Through the above specific structural design, the detection liquid adding component 9 can quickly inject detection liquid into the goji berry samples divided into each sampling box 4.

[0035] See instruction manual attached Figure 3 and 4As shown, the dividing box structure 5 includes a sample dividing box body 501. The axial cross-sectional shape of the sample dividing box body 501 is W-shaped. A vibration motor 507 is installed on the top side of the middle part of the sample dividing box body 501. In practical applications, the vibration motor 507 can play a dual role. The first role is to evenly distribute the wolfberry sample in the sample dividing box body 501, which facilitates subsequent equal-volume dividing. The second role is to fully discharge the wolfberry sample from the feeding slots 511 under vibration, preventing the wolfberry sample from remaining in the sample dividing box body 501. The bottom surface of the sample dividing box body 501 has several feeding slots 51 evenly distributed at equal angles with its central axis as the center. 1. In practical applications, the feeding slot 511 is used to discharge the equally divided wolfberry samples downwards into the sampling box 4. The feeding slot 511 is circular in shape, which can also be adapted to the contour shape between the two adjacent dividing slots 503, ensuring that the wolfberry samples fall into the sampling box 4 and avoiding residue in the sample dividing box 501. Each feeding slot 511 has a funnel 509 that is wider at the top and narrower at the bottom at the lower opening. Dividing slots 503 are opened on the side wall of the sample dividing box 501 between the two feeding slots 511. Dividing plates 506 are slidably arranged in each dividing slot 503. The two sides are fixedly connected to each other by a connecting top plate 512. An electric telescopic rod 510 is fixedly installed at the center of the bottom surface of the sample dividing chamber. The push rod head of the electric telescopic rod 510 is fixedly connected to the lower side of the connecting top plate 512. A sealing cover 502 is installed directly above each feeding slot 511. The upper side of the sealing cover 502 is a convex spherical surface. The two sides of the sealing cover 502 are fixedly connected to the top side of the dividing plate 506 by connecting ribs 504. A soft baffle plate 508 is fixedly installed along the edge of the top side of the dividing plate 506. The output terminal of the PLC controller 2 is electrically connected to the input terminal of the vibration motor 507. When the push rod of the electric telescopic rod 510 reaches... When the maximum stroke is reached, the connecting top plate 512 and the dividing plate 506 move to the top side inside the sample dividing box 501. At this time, the dividing plate 506 divides the sample dividing box 501 into several dividing chambers. The sealing cover 502 separates from the discharge hole groove 511. Then, the connecting top plate 512 drives the dividing plate 506 to slide up and down in the dividing slot 503. When the push rod of the electric telescopic rod 510 reaches the minimum stroke, the connecting top plate 512 and the dividing plate 506 move to the bottom side inside the sample dividing box 501. At this time, the several dividing chambers inside the sample dividing box 501 form a connected whole, and the sealing cover 502 seals the discharge hole groove 511.

[0036] The top outer edge of the sample dividing box 501 is formed with a retaining edge 505. Further, the retaining edge 505 has a height of 2mm-6mm and is made of silicone material. Four or more springs 14 are fixedly connected to the lower side of the retaining edge 505, evenly distributed at equal angles around the central axis of the sample dividing box 501. The upper edge of the sampling box 1 has corresponding insertion holes for each spring 14, the depth of which is less than the length of the spring 14. A lid structure 6 is provided on the upper side of the sample dividing box 501.

[0037] The detection liquid addition assembly 9 includes a liquid pump 9a fixedly installed on the bottom surface inside the detection liquid storage chamber 10. The outlet of the liquid pump 9a is connected to one end of the liquid outlet pipe 9b. The other end of the liquid outlet pipe 9b passes through the detection liquid storage chamber 10 and is connected to an annular liquid passage pipe 9d. The annular liquid passage pipe 9d passes through the top of each sampling slot 3 in sequence and is fixedly installed on the inner wall of the sample dividing chamber. The annular liquid passage pipe 9d is connected to branch liquid guide pipes 9c corresponding to each sampling slot 3. Each branch liquid guide pipe 9c is equipped with a solenoid valve 9e. The output terminal of the PLC controller 2 is electrically connected to the input terminal of the liquid pump 9a and the solenoid valve 9e respectively.

[0038] One of the sampling tanks 3 has a liquid addition pipe 11 installed on its inner bottom surface. The bottom end of the liquid addition pipe 11 is connected to the inside of the detection liquid storage chamber 10. The upper end of the liquid addition pipe 11 is detachably equipped with a sealing cap 12. Furthermore, the sealing cap 12 is connected to the liquid addition pipe 11 by a threaded connection. A transparent observation plate 7 is installed on the outer wall of the sampling box 1 near the detection liquid storage chamber 10. Through the above-mentioned structural design, the operator can observe the liquid volume inside the detection liquid storage chamber 10 through the transparent observation plate 7. When the liquid volume in the detection liquid storage chamber 10 is low, the sealing cap 12 at the upper end of the liquid addition pipe 11 can be removed, and detection liquid can be added to the detection liquid storage chamber 10 through the liquid addition pipe 11.

[0039] The sampling box 4 is shaped like an elliptical cylinder with a hollow interior and an open top. A handle 4a is fixedly installed on the outer wall of one end along its long axis. The handle 4a is L-shaped. Each sampling slot 3 has a baffle 13 fixedly installed inside for positioning the sampling box 4. In practical applications, the sampling box 4 adopts an elliptical cylinder shape. One focal point of the sampling box 4 is located directly below the discharge slot 511, while the other focal point is located directly below the outlet of the branch liquid pipe 9c.

[0040] The lid structure 6 includes a top cover 6a. A flange 6b is fixedly provided along the lower edge of the top cover 6a, which engages with the upper opening edge of the sample dividing box 501. The flange 6b ensures a seal at the connection point with the upper opening of the sample dividing box 501. The top cover 6a is made of transparent material, and a handle 6c is fixedly provided on the upper side of the top cover 6a. In practical applications, the lid structure 6 protects the goji berry samples when dividing them into equal portions.

[0041] Working principle:

[0042] After weighing a certain amount M of the goji berry sample to be tested using an electronic weighing device, open the box cover structure 6. First, push the electric telescopic rod 510 to its minimum stroke, with the sealing cover 502, dividing plate 506, and connecting top plate 512 all at their lowest positions. At this time, the sealing cover 502 seals the discharge slot 511. The internal spaces of the sample dividing box 501 are connected. Then, pour the goji berry sample weighing M into the sample dividing box 501. After pouring the goji berry sample weighing M into the sample dividing box 501, P... LC controller 2 controls the opening of the vibration motor 507 located on the top side of the sample dividing box 501. The vibration motor 507 vibrates, causing the sample dividing box 501 to vibrate. At this time, the outer edge of the sample dividing box 501 is elastically supported by spring 14, allowing the sample dividing box 501 to sway within the elastic range of spring 14. This ensures that the wolfberry sample is evenly distributed within the dividing box structure 5, meaning that the upper surface of the wolfberry sample remains horizontal within the sample dividing box 501. When dividing the wolfberry sample into equal portions, the electric... The telescopic rod 510 extends upward, thereby moving the sealing cover 502, the dividing plate 506, and the connecting top plate 512 upward. The dividing plate 506 divides the goji berry sample into several equal portions. In practical applications, 6, 8, 10, or 12 dividing plates 506 are provided, correspondingly dividing the goji berry sample into 6, 8, 10, or 12 portions. At this time, the sealing cover 502 separates from the discharge slot 511. The upper side of the sealing cover 502 is a convex spherical surface, allowing the goji berry sample to slide off the upper surface of the sealing cover 502, avoiding... The goji berry sample remains on the upper surface of the sealing cap 502. The goji berry samples, after being divided into equal amounts, enter the sampling box 4 in the sampling tank 3 through the feeding hole groove 511 and the funnel 509. The detection liquid adding component 9 adds the detection liquid in the detection liquid storage chamber 10 into each sampling box 4. The PLC controller 2 controls the opening of the liquid pump 9a and the solenoid valve 9e. The liquid pump 9a sequentially inputs the detection liquid into the sampling box 4 through the liquid outlet pipe 9b, the annular liquid passage pipe 9d and the branch liquid guide pipe 9c. Finally, the sampling box 4 can be removed from the sampling tank 3. In practical applications, the PLC controller 2 controls the solenoid valve 9e on the branch liquid pipe 9c, thereby enabling the flow or closure of the branch liquid pipe 9c. Correspondingly, the dividing plate 506 is detachably connected to the connecting top plate 512 by bolts, thereby allowing the number of dividing plates 506 to be increased or decreased, thus enabling the sampling of different quantities of goji berry samples. In practical applications, the gap of the dividing slot 503 is smaller than the outer diameter of the goji berry to prevent the goji berry from falling into the gap of the dividing slot 503.

[0043] The sampling device used in this application is suitable for dividing goji berries into equal portions, but is not limited to goji berries. It can be used for similar granular materials, such as rice, soybeans, and other bean granules.

Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in the present invention should be included within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the scope of the claims.

The sealing cover (502), the dividing plate (506) and the connecting top plate (512) are all at their lowest positions. At this time, the sealing cover (502) seals the discharge hole groove (511). S2: The vibration motor (507) installed on the top side of the sample dividing box (501) is opened by the PLC controller (2). The vibration motor (507) vibrates and drives the sample dividing box (501) to vibrate, thereby achieving uniform distribution of wolfberry samples in the dividing box structure (5). S3: The electric telescopic rod (510) of the dividing box structure (5) extends upward, thereby driving the sealing cover (502), the dividing plate (506) and the connecting top plate (512) to move upward. The dividing plate (506) divides the sample wolfberry into several equal portions. At this time, the sealing cover (502) is separated from the feeding hole groove (511). The wolfberry samples after equal division enter the sampling box (4) in the sampling groove (3) through the feeding hole groove (511) and the funnel (509) in sequence. S4: The detection liquid addition component (9) adds the detection liquid from the detection liquid storage chamber (10) into each sampling box (4). The PLC controller (2) controls the opening of the liquid pump (9a) and the solenoid valve (9e). The liquid pump (9a) sequentially inputs the detection liquid into the sampling box (4) through the liquid outlet pipe (9b), the annular liquid passage pipe (9d) and the branch liquid guide pipe (9c). Finally, the sampling box (4) is taken out from the sampling tank (3).
