[0064] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0065] In the description of the present invention, it should be understood that descriptions involving orientation, such as up, down, front, back, left, right, etc., indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0066] In the description of the present utility model, "several" means more than one, "many" means more than two, "greater than", "less than", "exceed" etc. are understood to exclude the number itself, and "above", "below", "within" etc. are understood to include the number itself. If there is a description of "first" or "second", it is only used to distinguish the technical features, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features or implicitly indicating the order of the indicated technical features.

[0067] In the description of the present invention, unless otherwise clearly defined, terms such as setting, installing, connecting, etc. should be understood in a broad sense, and technicians in the relevant technical field can reasonably determine the specific meanings of the above terms in the present invention based on the specific content of the technical solution.

[0068] In the description of the utility model, the description with reference to the terms "one embodiment", "some embodiments", "illustrative embodiments", "examples", "specific examples", or "some examples" means that the specific features, structures, materials or characteristics described in conjunction with the embodiment or example are included in at least one embodiment or example of the utility model. In this specification, the schematic representation of the above terms does not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials or characteristics described can be combined in any one or more embodiments or examples in a suitable manner.

[0069] At present, the sample processing system is usually integrated with a loading device, which is used to transfer the sample container. During the transfer process, the posture of the sample container is adjusted so that a single sample container can be output in an inverted horizontal posture (horizontal posture). In the related art, the loading device includes a pushing mechanism, an inner warehouse and an outer warehouse. The inner warehouse is arranged inside the housing, and the outer warehouse is arranged outside the housing. After the user pours the scattered and disordered sample containers into the outer warehouse, the sample containers will enter the inner warehouse from the outer warehouse and be sorted and output by the pushing mechanism. The sample container in the inner warehouse is lifted upward by the pushing mechanism to transfer the sample container to the discharge port for output. During the lifting process, the sample container needs to be tilted and placed horizontally before it can pass through the discharge port. Since the number of sample containers entering the inner warehouse is large and scattered, some sample containers are pushed upward by the pushing mechanism in an upright or inclined posture, resulting in the sample container being unable to pass through the discharge port normally, affecting the output of the sample container and reducing the output efficiency of the sample processing system.

[0070] Based on the above problems, the present invention proposes a sample processing unit 20, which can sort the sample containers 10 by setting a sample loading component 200 to ensure that the sample containers 10 are output in a horizontal posture, which is described below in conjunction with the accompanying drawings and specific embodiments.

[0071] Before describing the solution, the relevant concepts involved in the utility model are first explained:

[0072] The sample container 10 refers to a container for carrying a sample to be tested or a tested sample, such as a test tube. Figure 1 , shows a schematic diagram of a sample container 10, the sample container 10 includes a tube body 11 and a cover 12, the cover 12 is connected to one end of the tube body 11, the outer diameter of the cover 12 is usually larger than the outer diameter of the tube body 11, and the color and material of the cover 12 are usually different from those of the tube body 11. The tube body 11 is attached with a barcode 13, and the barcode 13 records the barcode 13 information related to the sample, which can be read by a barcode scanning device or a visual device. For the convenience of description, the sample container 10 carrying the sample to be tested is named as the container to be tested, and the container carrying the tested sample is named as the tested container.

[0073] The sample carrying component refers to a component for placing the sample container 10, such as a tray or a sample rack, wherein the tray or the sample rack has a plurality of sockets, each of which is used to place a sample container 10, wherein the sample rack generally includes a single row of sockets, and the tray includes multiple rows and columns of sockets arranged in an array. The top of the sample rack is provided with a plurality of first sockets, and the side is provided with slots corresponding to the first sockets. The first sockets are used to fix the sample container 10, and the slots are used for an external barcode scanning device or a visual device to read the barcode 13 information.

[0074] Reference Figures 2 to 4 , respectively showing a three-dimensional schematic diagram of the sample processing unit 20 of the first embodiment of the utility model, a three-dimensional schematic diagram of the hidden shell, and a brief schematic diagram showing the connection relationship between the sample loading component 200 and the shell. It should be noted that, Figure 4 As shown in the figure, the sample processing unit 20 in this embodiment includes a housing component 100, a sample loading component 200, a transfer component 300 and an output component 400, the sample loading component 200, the transfer component 300 and the output component 400 are all connected to the housing component 100, and the transfer component 300 and the output component 400 are arranged in the housing component 100.

[0075] Reference Figures 4 to 6The loading assembly 200 includes a material bin 201 and a feeding mechanism 230. The material bin 201 is used to store sample containers 10. The feeding mechanism 230 is used to sort the sample containers 10 in the material bin 201, thereby sorting out a single sample container 10 and sending the single sample container 10 out in a horizontal posture. Specifically, the housing assembly 100 includes a relatively independent first housing 110 and a second housing 120. In some embodiments, the aforementioned material bin 201 is a first material bin 210. The loading assembly 200 also includes a second material bin 220 connected to the first material bin 210. The first material bin 210 is located in the first housing 110, and the second material bin 220 is located in the second housing 120. The second material bin 220 is provided with an inlet 121 for users to pour the sample containers 10. The inlet 121 is provided at a position convenient for users to pour, such as the top of the second material bin 220. Based on the above structure, when the sample loading component 200 is provided with a second material bin 220, the user can directly pour the sample container 10 into the second material bin 220, and the sample container 10 flows into the first material bin 210 under the action of gravity. When the sample loading component 200 is not provided with a second material bin 220, a corresponding door body can be provided on the first shell 110. When sampling is required, after opening the corresponding door body on the first shell 110, the sample container 10 can be directly poured into the first material bin 210.

[0076] It should be noted that the number of the first silo 210 can be one or more. Figure 5 and Figure 6 As shown, the sample loading component 200 includes two first material bins 210, and the two first material bins 210 are arranged side by side along the left-right direction shown in the figure. Accordingly, the feeding mechanism 230 and the second material bin 220 can also be set to multiple. It should also be noted that when the sample loading component 200 is provided with the second material bin 220, the first material bin 210 and the second material bin 220 can be directly connected, and the sample container 10 can flow directly from the second material bin 220 into the first material bin 210. The two can also be connected through a transmission component, and the sample container 10 flows from the second material bin 220 into the transmission component, and then flows from the transmission component into the first material bin 210.

[0077] Specific to Figures 5 to 7 In the embodiment, the first silo 210 includes a silo bottom wall 211 and a silo side wall 212, which together define a storage space for storing sample containers 10 entering the first silo 210, for example, for storing sample containers 10 flowing from the second silo 220 into the first silo 210. In some specific embodiments, the first silo 210 also includes a silo top wall, a silo bottom wall 211 and a silo side wall 212, which together define a substantially closed storage space. In other specific embodiments, the top of the first silo 210 is as shown in FIG. Figure 5 , Figure 6Open setting shown.

[0078] Reference Figure 3 As shown, the transfer assembly 300 is used to receive a single sample container 10 sorted by the feeding mechanism 230, and transfer the single sample container 10 to the output assembly 400. The movement of the transfer assembly 300 to transfer the single sample container 10 may include horizontal movement, vertical movement, or a combination of horizontal movement and vertical movement. For example, the transfer assembly 300 includes a horizontally arranged transmission track, and the transmission track is used to transmit the sample container 10 in the horizontal direction. For another example, the transfer assembly 300 includes a vertically arranged lifting mechanism, which can transport the sample container 10 from a lower position to a higher position, or from a higher position to a lower position. For another example, the transfer assembly 300 includes a flipping mechanism, which is used to flip the sample container 10 from a horizontal position to a vertical position with the cover 12 facing upward. In a specific embodiment, the transfer assembly 300 includes the aforementioned transmission track, flipping mechanism and lifting mechanism. The transmission track transfers the horizontally placed sample container 10 to the flipping mechanism, and the flipping mechanism drives the sample container 10 to flip from a horizontal position to a vertical position, and then the lifting mechanism drives the flipping mechanism to move upward, so that the upright sample container 10 moves to a higher position. The present embodiment does not limit the specific manner in which the transfer component 300 transfers the sample container 10 . For example, the transfer component 300 may drive the sample container 10 to move horizontally through a conveyor belt, or may drive the sample container 10 to move horizontally through a pushing mechanism.

[0079] Reference Figure 3As shown, the output component 400 is used to receive a single sample container 10 from the transfer component 300, and output a single sample container 10 or at least one single sample container 10 carried on a sample carrying component. In some specific embodiments, the output component 400 outputs a single sample container 10. Such an output component 400 generally includes a manipulator capable of transferring a single sample container 10, which is suitable for an analysis system that uses a single tube holder as a carrier for transmission. For example, the analysis system includes a track unit, and a plurality of empty single tube holders are transported on the track unit. Then, the output component 400 can directly transfer the single sample container 10 to the single tube holder on the track unit. In other specific embodiments, the output component 400 outputs a sample carrying part that carries a single sample container 10. Such an output component 400 generally includes a manipulator capable of transferring the sample carrying part, or a pushing mechanism capable of pushing out / introducing the sample carrying part, and a storage area for the sample carrying part, which is suitable for an analysis system that uses the sample carrying part as a carrier for transmission. For example, the analysis system includes a track unit, and the track unit is docked with the sample processing unit 20. After the output component 400 receives the single sample container 10 from the transfer component 300, it first transfers the single sample container 10 to the sample carrying part in the storage area, and then further transfers the sample carrying part to the track unit through the manipulator or the pushing mechanism. Specifically, the sample carrying part refers to a part for placing the sample container 10, such as a tray or a sample rack, the tray or the sample rack having a plurality of sockets, each socket for placing a sample container 10, wherein the sample rack generally includes a single row of sockets, and the tray includes a plurality of rows and columns of sockets arranged in an array.

[0080] As mentioned above, in the embodiment of the present invention, the sample loading assembly 200 is used to sort the sample containers 10, sort out a single sample container 10, and send the single sample container 10 out in a horizontal posture.

The movable plate 231a and the fixed plate 231b are both square plate structures, and the two are arranged side by side, wherein the fixed plate 231b is fixedly arranged relative to the silo 201, that is, the position of the fixed plate 231b is fixed, and the movable plate 231a is connected to the first driving component 232, and the movable plate 231a is driven by the first driving component 232 to move relative to the fixed plate 231b.

[0082] Specifically, driven by the first driving component 232, the movable plate 231a can reciprocate between the first position and the second position, the first position is lower than the second position, the first position is the lowest point of the movable plate 231a movement process, and the second position is the highest point of the movable plate 231a movement process. In the first position, the top of the movable plate 231a is lower than the top of the fixed plate 231b, and at this time, the top of the movable plate 231a receives the sample container 10 in the first bin 210, and the sample container 10 does not move toward the fixed plate 231b. In order to transfer the sample container 10 in the first bin 210 to the top of the movable plate 231a, the top of the movable plate 231a needs to be set lower than the bin bottom wall 211 of the first bin 210 when it is in the first position, so that the sample container 10 can roll from the bin bottom wall 211 to the top of the movable plate 231a. After the top of the movable plate 231a receives the sample container 10, the first driving component 232 drives the movable plate 231a to move toward the second position, and the sample container 10 can be lifted upward by the movable plate 231a. When the movable plate 231a is in the second position, the top of the movable plate 231a is not lower than the top of the fixed plate 231b, that is, the top of the movable plate 231a is higher than the top of the fixed plate 231b, so that the sample container 10 can be transferred from the top of the movable plate 231a to the top of the fixed plate 231b. After the sample container 10 reaches the top of the fixed plate 231b, it can move toward the discharge port 244 of the first bin 210 to achieve the output of the sample container 10. In some embodiments, the first driving component 232 includes a motor, and the motor can be connected to the movable plate 231a through a transmission component. For example, the output shaft of the motor drives the movable plate 231a to move through a transmission gear. Driven by the motor, the movable plate 231a reciprocates between the first position and the second position.

[0083] It can be understood that, in the first feeding component 231, the spacing between the movable plate 231a and the fixed plate 231b is smaller than the minimum diameter of the sample container 10, and the length of the top of the movable plate 231a and the fixed plate 231b is greater than the length of the sample container 10, and the width of the top of the movable plate 231a and the fixed plate 231b can meet the requirements of stably supporting the sample container 10. For example, the width of the top of the movable plate 231a and the fixed plate 231b is set to be greater than or equal to the diameter of the sample container 10.

[0084] In some specific embodiments, the number of first feeding components 231 is not limited to one, and two or more first feeding components 231 may be provided. The two or more first feeding components 231 are arranged in sequence along the front-to-back direction to form multi-stage first feeding components 231, and the height of the fixed plate 231b of each stage gradually increases, and the height of the movable plate 231a of each stage gradually increases. The movable plates 231a of each stage are connected to the first driving component 232, and the first driving component 232 can drive the movable plates 231a of each stage to move synchronously, wherein the first feeding component 231 where the fixed plate 231b with the lowest top height is located is located at the first stage, and the first feeding component 231 where the fixed plate 231b with the highest top height is located is located at the last stage, and along the direction from the first stage to the last stage, the first feeding components 231 of each stage are arranged in sequence. In the first feeding component 231 of the first stage, the passive plate 231a of the sample container 10 is lifted to the top of the fixed plate 231b, and is transferred from the top of the fixed plate 231b to the top of the movable plate 231a of the first feeding component 231 of the next stage. In this way, the reciprocating motion can lift the sample container 10 up step by step, and the sample container 10 can be output to the discharge port 244 through the first feeding component 231 of the last stage.

[0085] Reference Figures 8 to 10 As shown, in the first feeding member 231, the fixed plate 231b includes a main body 2311b and at least two protrusions 231c, at least two protrusions 231c are connected to the upper end of the main body 2311b, and are spaced apart along the extension direction of the upper end of the main body 2311b, and the extension direction is Fig.10 In the left and right directions shown in , the main body 2311b is a square plate, and the protrusion 231c is arranged on the upper end surface of the main body 2311b by a fixed connection, or the protrusion 231c and the main body 2311b are formed in one piece, so the structure is more stable. Since the protrusion 231c is added to the top of the main body 2311b, the end of the protrusion 231c away from the main body 2311b is the top of the fixed plate 231b, and the height difference between the top of the fixed plate 231b and the top of the main body 2311b is the height of the protrusion 231c. The sample container 10 is supported by the protrusion 231c, and the sample container 10 is placed on the top of the protrusion 231c in a horizontal posture when it is tilted, that is, the sample container 10 can lie flat on the top of the fixed plate 231b.

[0086] In the embodiment, four protrusions 231c are provided at the top of the main body 2311b, and the four protrusions 231c are evenly distributed along the upper end surface of the main body 2311b. The distance between two adjacent protrusions 231c is smaller than the length of the sample container 10, so as to prevent the sample container 10 from falling downward through the gap between the two protrusions 231c when it is tilted, and the sample container 10 can pass through the gap between the two adjacent protrusions 231c when it is in an upright or inclined posture; in addition, there is also a gap between the protrusion 231c close to the left or right edge of the main body 2311b and the side of the main body 2311b, and the sample container 10 can also pass through the gap when it is in an upright or inclined posture.

[0087] Among them, an inclined separation surface 231d is formed at the upper end of the main body 2311b, and the separation surface 231d is inclined downward in the direction of the movable plate 231a. Specifically, the bottom wall 211, the movable plate 231a and the fixed plate 231b of the first material bin 210 are arranged in sequence along the front-to-back direction, and the separation surface 231d is specifically inclined downward toward the bin bottom wall 211. The sample container 10 falling from the above-mentioned gap can fall back onto the bin bottom wall 211 under the guidance of the separation surface 231d, avoiding the sample container 10 from being pushed upward in an upright or inclined posture, and the sample container 10 in a horizontal posture can lie flat on the top of the fixed plate 231b, ensuring that the sample container 10 is output in a horizontal posture, which helps to improve the output efficiency of the sample processing unit 20. In some embodiments, the inclination angle of the separation surface 231d is set to be greater than 30°. For example, the inclination angle of the separation surface 231d can be 45°, 60°, etc., so that the sample container 10 can fall along the separation surface 231d and avoid the sample container 10 being stuck on the separation surface 231d.

[0088] Fig.10The protrusion 231c shown in the figure is a flat plate structure. The width dimension of the protrusion 231c along the left-right direction of the fixed plate 231b is much smaller than the size of the sample container 10. The protrusion 231c occupies a small space on the upper end surface of the main body 2311b, thereby preventing the sample container 10 from being placed on the top of the protrusion 231c in an upright or inclined posture. In other embodiments, the protrusion 231c can also be set to a cylindrical, polygonal columnar or other structure. In addition, the above embodiments are only examples, and the number of protrusions 231c is not limited to four. Two, three or more protrusions 231c can also be set, which is selected according to the size of the fixed plate 231b and the sample container 10. In order to ensure that the feeding mechanism 230 pushes a single sample container 10 for output, the length dimensions of the fixed plate 231b and the movable plate 231a along the left and right directions in the embodiment are not greater than the total length of the two sample containers 10; of course, in other embodiments, when two or more sample containers 10 need to be output at the same time, the length dimensions of the fixed plate 231b and the movable plate 231a can also be set to be greater than the total length of the two sample containers 10, that is, the top ends of the fixed plate 231b and the movable plate 231a can simultaneously lie flat on two or more sample containers 10.

[0089] Reference Fig. 9 As shown, the end surface of each protrusion 231c away from the main body 2311b is set as a first inclined surface 231e, and the first inclined surface 231e is set to be inclined downward in the direction away from the movable plate 231a. When the sample container 10 moves from the top of the movable plate 231a to the top of the protrusion 231c, the first inclined surface 231e guides the sample container 10, so that the sample container 10 can be more easily rolled to the discharge port 244 or the movable plate 231a of the next-level first feeding component 231. As shown in the figure, the inclination direction of the first inclined surface 231e is opposite to the inclination direction of the separation surface 231d, ensuring that the sample container 10 in a horizontal posture can be transferred smoothly, and the vertical or inclined sample container 10 can fall back downward. In some embodiments, the inclination angle of the first inclined surface 231e is set to be no greater than 30°, so as to facilitate the sample container 10 to flow to the discharge port 244 or the moving plate 231a of the next level. For example, the inclination angle of the first inclined surface 231e can be 20°, 25°, 30°, etc., to avoid the sample container 10 rolling too fast due to its excessive inclination angle, thereby protecting the sample container 10.

[0090] Taking into account the possibility that the sample container 10 may lean against a certain angle, when the sample container 10 is in a leaning position, its lower end is stuck between two adjacent protrusions 231c, and its upper end is leaning against the side plate or other upright plate of the rack 240. In order to solve this problem, two or more protrusions 231c are reasonably arranged. In some embodiments, the spacing between two adjacent protrusions 231c is set to be larger than the maximum diameter of the sample container 10. Here, the maximum diameter of the sample container 10 refers to the outer diameter of its cover 12, because usually, the outer diameter of the cover 12 of the sample container 10 is larger than the outer diameter of the tube body 11. This ensures that the sample container 10 can pass between any two adjacent protrusions 231c and fall along the separation surface 231d, thereby preventing the sample container 10 from staying on the top of the moving plate 231a in a leaning position.

[0091] It should be noted that, since different sample containers 10 have different length dimensions, the first silo 210 can simultaneously store multiple sample containers 10 with different length dimensions. In order to make the distribution of the protrusions 231c meet the feeding requirements of sample containers 10 of different sizes and enable each sample container 10 to be output in a horizontal posture, in some specific examples, it is necessary to meet the requirement that the spacing between two adjacent protrusions 231c is smaller than the minimum length of the sample container 10, and the distance between three adjacent protrusions 231c is smaller than the maximum length of the sample container 10, thereby ensuring that the sample container 10 in an upright or inclined posture can pass through the adjacent protrusions 231c and fall, and the sample container 10 in a horizontal posture can be pushed normally for output.

[0092] In other embodiments, at least two protrusions 231c are spaced apart from each other on the upper end of the main body 2311b and are symmetrically arranged with the central axis of the main body 2311b as the symmetry axis. Fig.10 The example shown is for explanation, the four protrusions 231c are divided into two groups, each group has two protrusions 231c, the central axis of the main body 2311b is the L axis, the two groups of protrusions 231c are symmetrically arranged on the upper end surface of the main body 2311b about the L axis, the two groups of protrusions 231c can simultaneously support the sample container 10 in a horizontal posture, and the spacing between the two groups of protrusions 231c is sufficient for the sample container 10 to pass through, or one of the protrusions 231c is located at the position of the central axis, and the protrusions 231c on both sides of the central axis are symmetrically arranged about the protrusion 231c at the position of the central axis. The layout spacing design of the protrusions 231c in this embodiment can adopt the structure of the aforementioned embodiment, that is, it is satisfied that the spacing between two adjacent protrusions 231c needs to be less than the minimum length of the sample container 10, and the distance between three adjacent protrusions 231c is less than the maximum length of the sample container 10.

[0093] The feeding mechanism 230 further includes a pushing member 260, which is disposed on the side of the movable plate 231a of the first feeding member 231 facing the fixed plate 231b. The pushing member 260 is connected to the movable plate 231a. When the motor drives the movable plate 231a to reciprocate, it can drive the pushing member 260 to move synchronously. The pushing member 260 can push down the sample container 10 located above the separation surface 231d. When the sample container 10 leans against the fixed plate 231b in an inclined posture, the pushing member 260 can push down the sample container 10 to make it tilt to a horizontal posture, or make the sample container 10 fall along the separation surface 231d, so as to prevent the sample container 10 from being in an upright or inclined posture and being unable to be pushed to the discharge port 244. For example, the pushing member 260 can be a push plate structure. When the push plate is driven to move by the movable plate 231a, the push plate can push the sample container 10 in an upright state. The pushing component 260 can push the sample container 10 from both sides, and can push the sample container 10 from bottom to top.

[0094] When the pushing member 260 moves from bottom to top, a through hole 231f can be set on the separation surface 231d, and the pushing member 260 can pass through the through hole 231f to push the sample container 10 located above the separation surface 231d, so that the sample container 10 is tilted to a horizontal posture or slides from the separation surface 231d, avoiding the sample container 10 from being stuck on the upper end of the fixed plate 231b.

[0095] Reference Fig.12As shown, the feeding mechanism 230 also includes a second feeding component 233, and the second feeding component 233 includes at least two movable plates 231a and at least one fixed plate 231b. The second feeding component 233 is arranged side by side with the first feeding component 231. The feeding mechanism 230 feeds the sample container 10 through the first feeding component 231 and the second feeding component 233 in sequence. The movable plates 231a of the first feeding component 231 and the second feeding component 233 are driven by the first driving component 232 to move. Along the direction from the first feeding component 231 to the second feeding component 233, the top surface height of each movable plate 231a increases in sequence, and the top surface height of each fixed plate 231b increases in sequence. It can be understood that since the movable plates 231a are not arranged at the same height, the first position and the second position of each movable plate 231a are not the same. Taking the first position as an example, the first position of each movable plate 231a increases in sequence along the direction from the first feeding component 231 to the second feeding component 233. In the second feeding component 233, the number of movable plates 231a is one more than the number of fixed plates 231b, and a fixed plate 231b is arranged between two adjacent movable plates 231a, wherein the movable plate 231a with the lowest top surface height is arranged close to the fixed plate 231b of the first feeding component 231, and when in the first position, the movable plate 231a receives the sample container 10 transferred from the fixed plate 231b of the first feeding component 231, so that the sample container 10 is pushed from the first feeding component 231 to the second feeding component 233.

[0096] Driven by the first driving component 232, the movable plate 231a of the second feeding component 233 can reciprocate between the first position and the second position. In the first position, in the second feeding component 233, the movable plate 231a with the lowest top surface height is lower than the top surface of the fixed plate 231b in the first feeding component 231. At this time, the top of the movable plate 231a receives the sample container 10 from the first feeding component 231. After the top of the movable plate 231a receives the sample container 10, the first driving component 232 drives the movable plate 231a to move toward the second position, and lifts the sample container 10 upward through the movable plate 231a. When the movable plate 231a is in the second position, the first driving component 232 drives the movable plate 231a to move toward the second position. The top of the moving plate 231a in the second feeding component 233 is not lower than the top of the fixed plate 231b adjacent thereto, and the sample container 10 can be transferred from the top of the moving plate 231a to the top of the fixed plate 231b in the second feeding component 233, and then transferred from the top of the fixed plate 231b to the next moving plate 231a. During the movement of the moving plate 231a, the fixed plate 231b remains stationary, so that the second feeding component 233 can feed the sample container 10 by alternately pushing the moving plate 231a and the fixed plate 231b. In some embodiments, when the sample container 10 reaches the moving plate 231a with the highest top surface height in the second feeding component 233, the sample container 10 can be pushed to the discharge port 244, thereby completing the output of the sample container 10.

[0097] It can be understood that, since the arrangement of the movable plates 231a and the fixed plates 231b is gradually increased along the feeding direction of the sample container 10, the more movable plates 231a and fixed plates 231b there are in the second feeding component 233, the higher the height of the sample container 10 is lifted, and the number of movable plates 231a and fixed plates 231b in the second feeding component 233 can be specifically selected according to the height difference between the discharge port 244 and the bottom wall 211 of the bin. The upper end of the main body 2311b of each fixed plate 231b in the second feeding component 233 is provided with a protrusion 231c and a separation surface 231d, and the specific structure of the protrusion 231c and the separation surface 231d can refer to the aforementioned embodiment of the first feeding component 231.

[0098] The difference between the second feeding component 233 and the first feeding component 231 is that the number of the movable plates 231a and the fixed plates 231b in the second feeding component 233 is not limited to one, and the second feeding component 233 can be provided with two or more movable plates 231a and fixed plates 231b, wherein the number of the fixed plates 231b is one less than the movable plates 231a, so that a fixed plate 231b is provided between two adjacent movable plates 231a; and the last plate body in the second feeding component 233 is the movable plate 231a, and the sample container 10 is pushed upward by the movable plate 231a, which can more flexibly cooperate with the discharge port 244 to complete the discharge operation.

[0099] Reference Fig.12 and Fig.13 As shown, for ease of understanding, the embodiment is specifically described. The movable plate 231a and the fixed plate 231b of the first feeding component 231 are respectively the first movable plate 2311 and the first fixed plate 2312. The second feeding component 233 includes two movable plates 231a and one fixed plate 231b. Along the direction from the first feeding component 231 to the second feeding component 233, the two movable plates 231a are respectively the second movable plate 2313 and the third movable plate 2315. The second feeding component The fixed plate 231b of 233 is the second fixed plate 2314, the first fixed plate 2312 is located between the first movable plate 2311 and the second movable plate 2313, the second fixed plate 2314 is located between the second movable plate 2313 and the third movable plate 2315, the top surface heights of the first movable plate 2311, the second movable plate 2313 and the third movable plate 2315 are increased in sequence, and the top surface heights of the first fixed plate 2312 and the second fixed plate 2314 are increased in sequence, and the whole is arranged in a stepped structure. The first movable plate 2311, the second movable plate 2313 and the third movable plate 2315 are all driven by a motor to move synchronously to reciprocate between the first position and the second position.

[0100] In addition, the first silo 210 also includes a frame 240, the frame 240 includes a left plate 241 and a right plate 242, the discharge port 244 is arranged at the top position of the frame 240, the first feeding component 231 and the second feeding component 233 are both installed between the left plate 241 and the right plate 242, wherein the first fixed plate 2312 and the second fixed plate 2314 are fixedly connected to the frame 240, and since the movable plate 231a and the fixed plate 231b are alternately distributed, the first fixed plate 2312 and the second fixed plate 2314 do not affect the movement of the first movable plate 2311, the second movable plate 2313 and the third movable plate 2315, and the top ends of the first fixed plate 2312 and the second fixed plate 2314 are respectively provided with a protrusion 231c and a separation surface 231d. During operation, the moving path of the sample container 10 passes through the first movable plate 2311, the first fixed plate 2312, the second movable plate 2313, the second fixed plate 2314 and the third movable plate 2315 in sequence, and during the pushing process of the feeding mechanism 230, the sample container 10 maintains a horizontal posture to move, and is pushed to the discharge port 244 for output by the third movable plate 2315. When the sample container 10 appears in an upright or inclined posture at the upper end of the second fixed plate 2314, the sample container 10 will slide down from both sides of the protrusion 231c and fall along the separation surface 231d to the first fixed plate 2312; if the sample container 10 still maintains an upright or inclined posture on the first fixed plate 2312, the sample container 10 will further slide down along the separation surface 231d of the first fixed plate 2312, and then fall back to the bottom of the first material bin 210.

[0101] It should be noted that the first movable plate 2311, the second movable plate 2313 and the third movable plate 2315 can also be driven separately by driving components, for example, each movable plate 231a is connected to a motor for driving. In addition, the feeding mechanism 230 also includes a mounting seat 235, and the first movable plate 2311, the second movable plate 2313 and the third movable plate 2315 are all connected to the mounting seat 235. The motor is connected to the mounting seat 235 or one of the movable plates 231a through a transmission component, so as to drive the above three movable plates 231a to move synchronously. In some specific embodiments, the first movable plate 2311, the second movable plate 2313 and the third movable plate 2315 have different heights. Along the direction from the first feeding component 231 to the second feeding component 233, the three movable plates 231a are arranged on the mounting seat 235 from low to high. The bottom of each movable plate 231a is fixedly connected to the mounting seat 235. A connecting seat 236 is provided on the back of the third movable plate 2315. The transmission component is specifically a transmission belt. The motor is connected to the transmission belt through gears, and the transmission belt is connected to the connecting seat 236. When the motor drives the transmission belt to move, the transmission belt can drive the connecting seat 236 to move, thereby achieving the purpose of driving the three movable plates 231a to move synchronously.

[0102] In other embodiments, the second feeding component 233 includes a movable plate 231a, and the movable plate 231a of the second feeding component 233 is arranged side by side with the fixed plate 231b of the first feeding component 231. Specifically, the first feeding component 231 includes a first movable plate 2311 and a first fixed plate 2312, and the second feeding component 233 includes a second movable plate 2313. When working, the first movable plate 2311 pushes the sample container 10 to the top of the first fixed plate 2312, and then rolls from the top of the first fixed plate 2312 to the top of the second movable plate 2313, and the sample container 10 is pushed to the discharge port 244 for output through the second movable plate 2313. The first movable plate 2311 and the second movable plate 2313 can be driven by the same motor or by different motors. In this embodiment, the second feeding component 233 adopts a single movable plate 231a structure combined with the first feeding component 231, which is beneficial to reducing the overall size of the feeding mechanism 230 and is suitable for a silo 201 with a smaller installation space.

[0103] Reference Figure 6 and Figure 7 As shown, the silo 201 is provided with a feed port 213, and the feeding mechanism 230 further includes at least one stirring plate 234, and at least one stirring plate 234 is arranged at intervals on the bottom wall 211 of the first silo 210, and is located between the first feeding component 231 and the feed port 213. Since the sample containers 10 are stored in the storage space in a disorderly manner, when the first feeding component 231 pushes the sample containers 10, the sample containers 10 in an upright or tilted posture are easily pushed, and when the sample containers 10 in an upright or tilted posture are transported to the fixed plate 231b, they will fall back to the storage space along the separation surface 231d, thus reducing the feeding efficiency. Therefore, the embodiment stirs the sample containers 10 by adding stirring plates 234, so that the sample containers 10 are transferred to the moving plate 231a of the first feeding component 231 in a horizontal or tilted posture, thereby improving the feeding efficiency.

[0104] Reference Fig.12 and Fig.13As shown, in some embodiments, two stirring plates 234 are provided, and the two stirring plates 234 are arranged at intervals. The upper end surfaces of the two stirring plates 234 are provided with fourth inclined surfaces 2341 inclined from the two ends of the stirring plates 234 to the middle, and the fourth inclined surfaces 2341 are inclined downward. When the stirring plates 234 move, when the fourth inclined surfaces 2341 contact the sample container 10, the upright or inclined sample container 10 can be pushed down, so that the sample container 10 can easily enter the first feeding component 231 in a horizontal posture. The feeding mechanism 230 also includes a second driving component, and the second driving component drives the stirring plates 234 to move in the up-down direction to achieve stirring of the sample container 10 in the storage space. This is only an example. The second driving component can also drive the stirring plates 234 to move in the left-right direction to achieve the purpose of stirring the sample container 10. In other embodiments, the stirring plates 234 can also be driven by the first driving component 232, that is, the first driving component 232 can drive the moving plate 231a and the stirring plates 234 to move synchronously.

[0105] Reference Figure 7 and 12 As shown, the feeding mechanism 230 also includes at least one pushing component 260, the number of which is consistent with the number of the fixed plates 231b, and the pushing component 260 is arranged on the side of the movable plate 231a facing the fixed plate 231b, and the pushing component 260 is connected to the movable plate 231a, and when the motor drives the movable plate 231a to reciprocate, it can drive the pushing component 260 to move synchronously, and when the sample container 10 leans against the fixed plate 231b in an inclined posture, the pushing component 260 can push the sample container 10 down, so that the sample container 10 is tilted to a horizontal posture, or the sample container 10 falls along the separation surface 231d, so as to prevent the sample container 10 from remaining in an upright or inclined posture and being unable to be pushed to the discharge port 244.

[0106] Reference Fig.12 and Fig.16As shown, a specific embodiment is used for explanation, the pushing component 260 is a structure of a hook 239, and two hooks 239 are provided. One hook 239 is arranged on the side of the second movable plate 2313 facing the first fixed plate 2312, and the other hook 239 is arranged on the side of the third movable plate 2315 facing the second fixed plate 2314. For example, on the second movable plate 2313, one end of the hook 239 is fixedly connected to the side wall of the second movable plate 2313, and the other end is extended from bottom to top. The upper ends of the first fixed plate 2312 and the second fixed plate 2314 are respectively provided with through holes 231f, which penetrate the separation surface 231d from bottom to top, and the through holes 231f are matched with the hooks 239. When the second movable plate 2313 and the third movable plate 2315 reciprocate, they respectively drive the corresponding hooks 239 to move. When moving to the second position, the upper ends of the hooks 239 on the second movable plate 2313 pass through the through hole 231f of the first fixed plate 2312 and protrude from the separation surface 231d, and the upper ends of the hooks 239 on the third movable plate 2315 pass through the through hole 231f of the second fixed plate 2314 and protrude from the separation surface 231d. When the sample container 10 is in a leaning state, the lower end of the sample container 10 is inserted between two adjacent protrusions 231c. At this time, the sample container 10 is pushed upward by the hook 239, thereby lifting one end of the sample container 10 and tilting the sample container 10 to a horizontal position.

[0107] It should be noted that when the sample container 10 is in a leaning state, its center of gravity is relatively low. At this time, the hook 239 only needs to push the partial structure of the lower end of the sample container 10 between the two protrusions 231c to make the sample container 10 leave the leaning state and return to a horizontal posture. The movement of the hook 239 does not need to be higher than the protrusion 231c, so as to avoid the hook 239 pushing the sample container 10 too high and breaking away from the support of the protrusion 231c.

[0108] Reference Fig.16As shown, in some specific embodiments, each hook 239 specifically includes a base 2391 and a claw 2392, and the hook 239 is connected to the movable plate 231a through the base 2391. Taking the second movable plate 2313 as an example, the base 2391 of the hook 239 is fixedly connected to the side wall of the second movable plate 2313, and the claw 2392 is extended downward and upward. A second inclined surface is provided at the top of the claw 2392, and the second inclined surface is inclined downward toward the second movable plate 2313. When the claw 2392 pushes the sample container 10, the guidance of the second inclined surface can facilitate the rolling of the sample container 10 toward the second movable plate 2313, thereby facilitating the transfer of the sample container 10. In the embodiment, two claws 2392 are provided, and the two claws 2392 are arranged at intervals. The separation surface 231d of the first fixed plate 2312 is provided with two through holes 231f. The two claws 2392 are respectively arranged opposite to the two through holes 231f. The two claws 2392 move synchronously and can extend or retract from the through holes 231f. The sample container 10 is pushed at the same time by the two claws 2392, which facilitates more efficient pushing down of the sample container 10.

[0109] Considering that the sample container 10 has a certain length, when the lower end of the sample container 10 is stuck in the protrusion 231c near the edge, the inclination angle of the sample container 10 is large, close to the upright state, and the stability of the leaning state is poor at this time, and it is easy to fall from the separation surfaces 231d on both sides of the protrusion 231c. When the sample container 10 is in the leaning state, and its lower end is stuck between the two middle protrusions 231c, the sample container 10 is not easy to fall and not easy to tip over. Therefore, in the embodiment, two claws 2392 are set between the two middle protrusions 231c, which can effectively solve the problem that the sample container 10 is easy to get stuck between the middle protrusions 231c. Of course, this is only an example, and the number of claws 2392 is not limited to two, and three or more claws 2392 can also be set, and the three or more claws 2392 can be distributed at the separation surfaces 231d at different positions.

[0110] Reference Fig.11 As shown, in order to improve the stability of the hook claw 239 during the movement process, a first guide groove 231g is respectively provided on one side of the first fixed plate 2312 and the second fixed plate 2314. The first guide groove 231g is extended in the up-down direction, and the first guide groove 231g is connected with the through hole 231f. The hook claw 239 is guided by the first guide groove 231g so that the hook claw 239 can stably slide toward the through hole 231f. Specifically, the first guide groove 231g includes two groove bodies, and the two claws 2392 are arranged in a one-to-one correspondence with the two groove bodies, which plays an effective guiding role and prevents the claw 2392 from deviating from the through hole 231f.

[0111] Reference Fig.14 and Fig.15As shown, the feeding mechanism 230 further includes a baffle 237 and a third material dividing component, the third material dividing component includes a fixed plate 2317, the fixed plate 2317 can be understood as a third fixed plate 2316, along the discharging direction of the discharging port 244, the third movable plate 2315, the third fixed plate 2316 and the baffle 237 are arranged in sequence, wherein the third fixed plate 2316 is fixedly connected to the frame 240, the baffle 237 is movably arranged on the back of the third fixed plate 2316, the baffle 237 is located below the discharging port 244, and the baffle 237 can open or close the discharging port 244. When the first driving component 232 drives the third movable plate 2315 to move, it can drive the baffle 237 to move. When the first driving component 232 drives the movable plate 231a to rise to the second position, the baffle 237 is driven to rise and block the discharge port 244 to close the discharge port 244, and the single sample container 10 rolls from the top of the third movable plate 2315 to the top of the third fixed plate 2316, and then when the movable plate 231a falls to the first position, the baffle 237 moves downward and opens the discharge port 244, so that the single sample container 10 at the top of the third fixed plate 2316 rolls to the discharge port 244, thereby ensuring that only a single sample container 10 can be output from the discharge port 244 at a time.

[0112] It should be noted that the difference between the third fixed plate 2316 and the first fixed plate 2312 and the second fixed plate 2314 is that the upper end of the third fixed plate 2316 does not have a protrusion 231c. Specifically, a third inclined surface 2316a can be set at the upper end of the third fixed plate 2316, and the third inclined surface 2316a is tilted downward in the direction of the baffle 237 to facilitate the sample container 10 to slide toward the discharge port 244.

[0113] Reference Fig.15As shown, in some embodiments, the feeding mechanism 230 also includes a support plate 238, which is fixedly connected to the frame 240, and the support plate 238 is arranged below the discharge port 244 and is located on the side of the baffle 237 facing away from the third fixed plate 2316. The baffle 237 is slidably arranged between the support plate 238 and the third fixed plate 2316. A stopper 2381 for supporting the baffle 237 is arranged on the side of the support plate 238 facing the baffle 237. When the third movable plate 2315 falls back to the first position, the baffle 237 moves downward, and the baffle 237 is moved downward by The stopper 2381 positions the baffle 237 to limit the baffle 237 from sliding downward, so that the baffle 237 stays below the discharge port 244 and keeps the discharge port 244 open; the first driving component 232 is provided with a thrust part 2361, and when the third movable plate 2315 moves toward the second position, the thrust part 2361 rises and pushes the baffle 237 to move upward, and when the third movable plate 2315 reaches the second position, the baffle 237 blocks the discharge port 244, thereby realizing the opening and closing of the discharge port 244. In some specific examples, the thrust part 2361 is a connecting seat 236 provided on the side of the third movable plate 2315 facing away from the second fixed plate 2314, and the connecting seat 236 moves synchronously with the third movable plate 2315, and the connecting seat 236 can abut against the lower end of the baffle 237 during the rising process and push the baffle 237 to move upward.

[0114] Reference Fig.13 As shown, the rack 240 includes a top plate 243, and a discharge port 244 is formed between the top plate 243 and the third movable plate 2315. The minimum distance between the top plate 243 and the third movable plate 2315 is greater than the maximum diameter of the sample container 10 and less than the length of the sample container 10. The top plate 243 is installed at the top of the left plate 241 and the right plate 242, and is located above the discharge port 244. Since the top plate 243 is tilted downward toward the discharge port 244, when the sample container 10 is pushed upward by the third movable plate 2315 in an upright posture, the sample container 10 is blocked when it contacts the top plate 243, thereby ensuring that the sample container 10 in an upright posture is blocked. In some embodiments, the top plate 243 is connected to the left plate 241 and the right plate 242 through a rotating shaft, so that the tilt angle of the top plate 243 can be adjusted, and the angle can be adjusted according to actual application requirements to avoid the sample container 10 being stuck at the discharge port 244.

[0115] Reference Fig.17 and Fig.18 As shown, in other embodiments, the pushing component 260 is a push plate 250, and the front sides of the second movable plate 2313 and the third movable plate 2315 are respectively provided with accommodating grooves 231h, and two push plates 250 are provided, and the two push plates 250 are respectively installed in the accommodating grooves 231h, and a rotating shaft 252 and a rocker rod 251 are respectively provided at both ends of each push plate 250, and the left plate 241 and the right plate 242 of the frame 240 are respectively provided with second guide grooves.

[0116] The assembly structure of the second movable plate 2313 and the push plate 250 is used as an example for explanation. The two sides of the receiving groove 231h of the second movable plate 2313 are respectively provided with shaft holes matching the rotating shaft 252. The rotating shafts 252 at both ends of the push plate 250 are respectively rotatably connected to the shaft holes at both ends, and the swing rods 251 at both ends of the push plate 250 are slidably connected to the second guide grooves on the two side plates, wherein the second guide groove has a connected straight groove section and a curved groove section, wherein the curved groove section is located at the upper end of the straight groove section. When the second movable plate 2313 moves upward, the swing rods 251 at both ends of the push plate 250 move upward along the straight groove section. When the push plate 250 moves, the moving directions of the rotating shaft 252, the swing rod 251 and the second movable plate 2313 are consistent with the guidance of the straight groove section. At this time, the push plate 250 is stored in the receiving groove 231h, and the surface of the push plate 250 is flush with the wall surface of the second movable plate 2313; when the swing rod 251 moves to the curved groove section, the moving directions of the swing rod 251 and the rotating shaft 252 are inconsistent. Under the guidance of the curved groove section, the push plate 250 is deflected around the rotating shaft 252, so that one end of the push plate 250 extends out of the receiving groove 231h and can push down the sample container 10 in an upright or inclined position on the first fixed plate 2312. When the second movable plate 2313 moves downward to a certain distance, the swing rod 251 of the push plate 250 is deflected, so that the push plate 250 gradually shrinks to be flush with the second movable plate 2313, so that the push plate 250 does not affect the movement of the second movable plate 2313. The working process of the push plate 250 on the third movable plate 2315 may refer to the description of the above embodiment.

[0117] In the embodiment, an abutment surface 253 is provided on the end surface of the push plate 250 away from the rotating shaft 252. The abutment surface 253 is used to contact the sample container 10. The abutment surface 253 is formed by the push plate 250 being inclined toward the middle direction along the axial direction of the rotating shaft 252 at both ends to form a concave surface. The cross section of the abutment surface 253 is V-shaped. When the push plate 250 is extended from the accommodating groove 231h, the abutment surface 253 contacts the upright or inclined sample container 10. The V-shaped concave surface can generate a thrust on the upright or inclined sample container 10, thereby pushing down the upright or inclined sample container 10, so that the sample container 10 is adjusted to a horizontal posture.

[0118] The embodiments of the utility model are described in detail above in conjunction with the accompanying drawings, but the utility model is not limited to the above embodiments. Various changes can be made within the knowledge of ordinary technicians in the relevant technical field without departing from the purpose of the utility model. In addition, the embodiments of the utility model and the features in the embodiments can be combined with each other without conflict.
