[0002] Currently, there is a sample processing system, which includes a test tube dumping processing device, which can pour the scattered and disordered test tubes containing samples into the dumping processing device of the sample processing system, and the dumping processing device can orderly organize and output the test tubes. Then, the sample processing system can clamp the test tubes organized by the dumping processing device to a multi-hole sample rack, or a single-hole / double-hole sample holder, so as to realize the automatic processing of disordered test tubes, thereby eliminating the operation of manually inserting test tubes into the test tube rack, and achieving the purpose of saving manpower. When the silo volume of the dumping processing device is limited, if a large number of test tubes are poured into the silo in a short time, it may cause the test tubes to be blocked, resulting in the test tubes being stuck and affecting the output of the test tubes.

[0051] 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.

[0052] 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.

[0053] 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.

[0054] In the description of the present utility model, 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 utility model based on the specific content of the technical solution.

[0055] 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.

[0056] As mentioned above, there is currently a sample input and output module that is integrated with a pouring type sample loading unit, which can support batch and disordered sample loading of sample containers. Specifically, the pouring type sample loading unit includes an inner compartment and an outer compartment, the inner compartment is arranged inside the housing of the sample input and output module, and the outer compartment is arranged outside the housing. After the user pours the scattered and disordered sample containers into the outer compartment, the sample containers will enter the inner compartment from the outer compartment, and will be sorted and output by the feeding mechanism. Since the inner compartment is arranged inside the housing of the sample input and output module, and the space inside the housing is limited, the volume of the inner compartment is usually also limited. For such a sample loading unit, if a large number of sample containers are poured into the outer compartment in a short time, the sample containers may be blocked in the inner compartment with a smaller volume, resulting in the inability of the feeding mechanism to sort the sample containers normally, thereby affecting the output of the sample containers. Based on the above problems, the utility model proposes a sample processing unit, which stirs the sample container by setting a stirring mechanism to improve the problem of blockage, which is described below in conjunction with the accompanying drawings and specific embodiments.

[0057] Reference Figures 1 to 3 , respectively showing a three-dimensional schematic diagram of the sample processing unit 1 of the first embodiment of the utility model, a three-dimensional schematic diagram of the hidden housing assembly 100, and a brief schematic diagram showing the connection relationship between the sample loading assembly 200 and the housing assembly 100. It should be noted that, Figure 3 The dotted frame in the figure indicates the approximate range of the housing assembly 100. As shown in the figure, the sample processing unit 1 in this embodiment includes a housing assembly 100, a sample loading assembly 200, a transfer assembly 300 and an output assembly 400. The housing assembly 100 includes a first housing 110. The sample loading assembly 200, the transfer assembly 300 and the output assembly 400 are all connected to the first housing 110, and the transfer assembly 300 and the output assembly 400 are disposed in the first housing 110.

[0058] Reference Figure 3 , Figure 4The sample loading component 200 includes a first material bin 210 and a feeding mechanism 230. The first material bin 210 is used to store sample containers. The feeding mechanism 230 is used to sort the sample containers in the first material bin 210, thereby sorting out a single sample container and sending the single sample container out in a set posture (for example, a horizontal posture). Specifically, the first material bin 210 is located in the first housing 110, that is, as an inner bin of the sample loading component 200. In some embodiments, refer to Figure 1 The housing assembly 100 further includes a second housing 120, and the first housing 110 and the second housing 120 are relatively independent. For example, the first housing 110 and the second housing 120 are arranged side by side. Figure 1 , Figure 2 The sample loading assembly 200 further includes a second material bin 220 connected to the first material bin 210. The second material bin 220 is located in the second housing 120, that is, it serves as an outer bin of the sample loading assembly 200. The second material bin 220 is provided with an inlet 221 for users to pour sample containers. The inlet 221 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 assembly 200 is provided with the second material bin 220, the user can directly pour the sample container into the second material bin 220, and the sample container flows into the first material bin 210 under the action of gravity. When the sample loading assembly 200 is not provided with the second material bin 220, a corresponding door body can be provided on the housing assembly 100. When it is necessary to load samples, the corresponding door body on the housing assembly 100 is opened and the sample container is directly poured into the first material bin 210.

[0059] It should be noted that the number of the first silo 210 can be one or more. Figure 4 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 front-to-back direction shown in the figure. Accordingly, the feeding mechanism 230 and the second material bin 220 can also be provided in multiples. 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 can flow directly from the second material bin 220 into the first material bin 210, and the two can also be connected by, for example Figure 2 The connecting component 270 shown is connected, and the sample container flows from the second material bin 220 into the connecting component 270 , and then flows from the connecting component 270 into the first material bin 210 .

[0060] Specific to Figures 6 to 8In 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 entering the first silo 210, for example, for storing sample containers 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, and the silo bottom wall 211, the silo side wall 212 and the silo top wall together define a substantially closed storage space. In other specific embodiments, the top of the first silo 210 is as shown in FIG. Figure 4 , Figure 5 Open setting shown.

[0061] The transfer component 300 is used to receive a single sample container sorted by the feeding mechanism 230 and transfer the single sample container to the output component 400. The movement of the transfer component 300 to transfer a single sample container may include horizontal movement, vertical movement, or a combination of horizontal movement and vertical movement. For example, the transfer component 300 includes a horizontally arranged transmission track, and the transmission track is used to transmit the sample container in the horizontal direction. For another example, the transfer component 300 includes a vertically arranged lifting mechanism, which can transport the sample container from a lower position to a higher position, or from a higher position to a lower position. For another example, the transfer component 300 includes a flipping mechanism, which is used to flip the sample container from a horizontal posture to a vertical posture with the cover facing up. In a specific embodiment, the transfer component 300 includes the aforementioned transmission track, flipping mechanism and lifting mechanism. The transmission track transfers the horizontally placed sample container to the flipping mechanism. The flipping mechanism drives the sample container to flip from a horizontal posture to a vertical posture, and then drives the flipping mechanism to move upward through the lifting mechanism, so that the upright sample container moves to a higher position. This embodiment does not limit the specific manner in which the transfer component 300 transfers the sample container. For example, the transfer component 300 may drive the sample container to move horizontally through a conveyor belt, or may drive the sample container to move horizontally through a pushing mechanism.

[0062] The output component 400 is used to receive a single sample container from the transfer component 300, and output a single sample container or at least one single sample container carried on a sample carrying component. In some specific embodiments, the output component 400 outputs a single sample container. Such an output component 400 generally includes a manipulator capable of transferring a single sample container, 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. The output component 400 can directly transfer the single sample container to the single tube holder on the track unit. In other specific embodiments, the output component 40 0 outputs a sample carrying component carrying a single sample container. Such an output component usually includes a manipulator capable of transferring the sample carrying component, or a pushing mechanism capable of pushing out / introducing the sample carrying component, and a storage area for the sample carrying component. It is suitable for an analysis system that uses the sample carrying component 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. After the output component 400 receives a single sample container from the transfer component 300, it first transfers the single sample container to the sample carrying component in the storage area, and then further transfers the sample carrying component to the track unit through the manipulator or the pushing mechanism. Specifically, the sample carrying component refers to a component for placing sample containers, such as a tray or a sample rack, and the tray or the sample rack has a plurality of sockets, each of which is used to place a sample container, wherein the sample rack usually includes a single row of sockets, and the tray includes multiple rows and columns of sockets arranged in an array.

[0063] As mentioned above, the first material bin 210 of the sample loading assembly 200 is disposed in the first housing 110. Figure 2 As shown, since the first housing 110 also needs to be filled with functional components such as the transfer component 300 and the output component 400, the volume of the first bin 210 is limited. If too many sample containers enter the first bin 210 in a short period of time, there is a possibility of blockage. Based on this, the sample loading component 200 of this embodiment also includes a stirring mechanism 240, which is used to stir the sample containers in the first bin 210, thereby driving the sample containers in the first bin 210 to move, thereby improving the problem of blockage and stagnation of the sample containers, and facilitating the feeding mechanism 230 to sort out a single sample container. It should be noted that this embodiment does not limit the specific movement mode of the stirring mechanism 240, which can achieve the stirring function by rotating or moving, which will be explained in subsequent embodiments.

[0064] Based on the first embodiment, in some embodiments of the present invention, referring to Figure 5 , Figure 6The stirring mechanism 240 includes a stirring member 241 and a first driving member. The stirring member 241 is disposed at the bottom of the first material bin 210 and can be driven by the first driving member to move relative to the bin bottom wall 211 of the first material bin 210 to stir the sample container. By disposing the stirring member 241 at the bottom of the first material bin 210, it can indirectly drive the upper sample container to move during stirring, thereby expanding the influence range of the stirring action. At the same time, the loading position of the feeding mechanism 230 is usually also disposed at the bottom of the first material bin 210. Therefore, the stirring member 241 can directly drive the sample container near the loading position to move when it moves at the bottom. The sample containers at these positions have a large movement amplitude, which is more conducive to breaking up the sample containers.

[0065] It should be noted that the term “the stirring member 241 is disposed at the bottom of the first silo 210” in the present invention is used to roughly describe the relative position of the stirring member 241 and the first silo 210, which can be understood as being closer to the bottom of the first silo 210 than the top of the first silo 210. In addition, the stirring member 241 may be entirely located in the first silo 210, that is, entirely located in the storage space, or only partially located in the first silo 210.

[0066] It should also be noted that the present embodiment does not limit the specific scheme of the first driving component. When the stirring mechanism 240 stirs by rotating, the first driving component may be a motor, which can directly drive the stirring mechanism 240 to rotate, or indirectly drive the stirring mechanism 240 to rotate through a transmission system such as a synchronous belt-synchronous wheel; when the stirring mechanism 240 stirs by moving, the first driving component may also be a motor, which indirectly drives the stirring mechanism 240 to move through a transmission system such as a synchronous belt-synchronous wheel, a screw-screw seat, a gear-rack, etc., and the first driving component may be an electric cylinder.

[0067] When the stirring mechanism 240 includes a stirring member 241 and a first driving member, in some embodiments of the present invention, Figure 5 , Figure 6 The stirring component 241 is configured to move in the up and down directions relative to the bottom wall 211 of the bin to stir the sample container. Specifically, when the stirring component 241 moves upward, its top will push the sample container to move. When the stirring component 241 moves downward, the sample container will move to fill the space left by the stirring component 241. In this way, as the stirring component 241 moves back and forth, the sample container can be stirred.

[0068] It should be noted that the “movement in the up-down direction” in this embodiment may refer to the stirring member 241 moving up and down in the vertical direction or moving upward in the inclined direction. In other words, the movement of the stirring member 241 only needs to have a movement component in the vertical direction.

[0069] When the stirring member 241 moves in the up and down direction to stir the sample container, in some embodiments of the present invention, Figure 6 The stirring member 241 is tilted relative to the horizontal plane, and the tilting direction is toward the feeding mechanism 230. For example, the feeding mechanism 230 is located on the left side of the stirring mechanism 240, and the stirring member 241 is toward Figure 6 Based on the above structure, the stirring member 241 in this embodiment is configured to move up and down relative to the bin bottom wall 211 along the inclined direction. In this way, during the upward movement of the stirring member 241, in addition to being able to drive the sample container to move upward, it can also drive the sample container to move toward the feeding mechanism 230, thereby achieving a better stirring effect.

[0070] When the stirring mechanism 240 includes a stirring member 241 and a first driving member, in some embodiments of the present invention, Figure 5 , Figure 6 Combined with Fig. 9 The stirring member 241 includes a first stirring portion 241a spaced apart from the feeding mechanism 230, and a first stirring portion 241a and a first stirring portion 241a are spaced apart from the feeding mechanism 230, for example, approximately along the direction of the first stirring portion 241a and the feeding mechanism 230. Figure 6 In the inclination direction of the bottom wall 211 of the middle chamber, the minimum distance between the two is greater than the diameter of the sample container. In this way, the gap between the first stirring part 241a and the feeding mechanism 230 can accommodate at least one sample container. While realizing the stirring and breaking function, it is convenient to accommodate the sample container between the first stirring part 241a and the feeding mechanism 230, thereby facilitating the feeding mechanism 230 to obtain the sample container from the gap.

[0071] It should be noted that the width of the gap between the first stirring part 241a and the feeding mechanism 230 can be constant. For example, when the feeding mechanism 230 is a push plate transfer mechanism, the minimum distance between the first stirring part 241a and the feeding mechanism 230 actually refers to the minimum distance between the first stirring part 241a and the lowest fixed plate 231 or the movable plate 232. When the first stirring part 241a is parallel to the lowest fixed plate 231 or the movable plate 232, the width of the gap between the two is constant; the width of the gap between the first stirring part 241a and the feeding mechanism 230 can also be variable. It should also be noted that the first silo 210 can store sample containers of different diameters. In this case, the so-called "diameter of the sample container" refers to the diameter of the largest sample container (including the container cover).

[0072] When the stirring mechanism 240 includes a stirring member 241 and a first driving member, in some embodiments of the present invention, Figure 5 , Figure 6 Combined with Fig. 9The stirring member 241 includes a second stirring portion 241b spaced apart from the feeding mechanism 230, and a direction along which the second stirring portion 241b and the feeding mechanism 230 are distributed, for example, approximately along Figure 6 In the inclined direction of the middle bin bottom wall 211, the maximum distance between the two is smaller than the diameter of a single sample container. In this way, when the second stirring portion 241b moves up and down relative to the bin bottom wall 211, it can push the sample container adjacent to the feeding mechanism 230 to move, thereby preventing the sample container from being in an upright position. It should be noted that, whether the feeding mechanism 230 adopts a push plate type solution or a chain plate type solution, it requires the sample container to be in a horizontal position when transporting a single sample container. In addition, during the process of transferring the sample container from the first bin 210 to the feeding mechanism 230, the sample container also needs to be in a horizontal position, or at least In an inclined posture, if the sample container is in an upright posture, on the one hand, it will be difficult to transfer the sample container to the feeding mechanism 230 (for example, the top of the sample container leans against the side wall of the bin, and therefore will not move to the feeding mechanism 230 under the action of gravity), causing the sample container to remain in the first bin 210. On the other hand, even if the sample container is transferred to the feeding mechanism 230, its upright state will affect further output, thereby causing an alarm shutdown. Based on this, this embodiment, by providing a second stirring portion 241b, can push the sample container to tip over, thereby improving related problems caused by the upright sample container.

[0073] It should be noted that the width of the gap between the second stirring part 241b and the feeding mechanism 230 can be constant. For example, when the feeding mechanism 230 is a push plate transfer mechanism, the maximum distance between the second stirring part 241b and the feeding mechanism 230 actually refers to the maximum distance between the second stirring part 241b and the lowest fixed plate 231 or movable plate 232. When the second stirring part 241b is parallel to the lowest fixed plate 231 or movable plate 232, the width of the gap between the two is constant; the width of the gap between the second stirring part 241b and the feeding mechanism 230 can also be variable. It should also be noted that the first silo 210 can store sample containers of different diameters. In this case, the so-called "diameter of the sample container" refers to the diameter of the smallest sample container (including the container cover).

[0074] When the stirring mechanism 240 includes a stirring member 241 and a first driving member, in some embodiments of the present invention, Figure 5 , Figure 6 Combined with Fig. 9, the stirring member 241 includes a first stirring portion 241a and a second stirring portion 241b, and the first stirring portion 241a and the second stirring portion 241b can be understood with reference to the aforementioned embodiment. In this embodiment, the first stirring portion 241a and the second stirring portion 241b are spaced apart, and the second stirring portion 241b is located on the side of the first stirring portion 241a facing the feeding mechanism 230. In this way, the stirring member 241 can both break up the sample container and reduce the uprightness of the sample container. In some specific embodiments, along the distribution direction of the first stirring portion 241a and the second stirring portion 241b, the minimum spacing between the two is greater than the diameter of a single sample container, so that the gap between the two can accommodate at least one sample container.

[0075] It should be noted that, in the aforementioned embodiments, the first stirring portion 241a can also play a certain role in preventing uprightness, and the second stirring portion 241b can also play a certain role in stirring and breaking up.

[0076] When the stirring member 241 moves in the up-down direction to stir the sample container, in some embodiments of the present invention, a guide portion is provided on the top of the stirring member 241, and the guide portion is configured such that when the sample container abuts against the guide surface and the stirring member 241 moves in the up-down direction relative to the bin bottom wall 211, the guide portion is used to guide the sample container to slide along the guide portion to change its posture. When the sample container is in a certain posture, it is also difficult for the stirring member 241 to directly stir and break it up. For example, the container cover of the sample container is hung on the top of the stirring member 241, and the top end is placed on the bin bottom wall 211. At the same time, the axis of the sample container is approximately located in a vertical plane. In this way, as the stirring member 241 moves up and down, the sample container will only change the angle between it and the stirring member 241 (for example, from tilting relative to the stirring member 241 to being approximately parallel to the stirring member 241), but will not separate from the stirring member 241, thereby also causing the sample container to be retained. By providing a guide portion, the present embodiment can drive the sample container to change its own posture through the up-down movement of the stirring member 241, thereby improving the problem of sample container retention.

[0077] When a guide portion is provided on the top of the stirring member 241, in some embodiments of the present invention, Fig. 9 The stirring component includes a first side and a second side that are arranged opposite to each other. For example, the first side is the left side in the figure, and the second side is the right side in the figure. Along the direction pointing from the first side to the second side, for example, from left to right in the figure, the guide portion includes a first guide surface 2411 and a second guide surface 2412 that are arranged in sequence.

[0078] In which, along the direction pointing from the first side to the second side, the distance between the first guide surface 2411 and the bottom wall 211 of the bin decreases. For example, the first guide surface 2411 may be an inclined surface or an arc surface. When the container cover of the sample container is hung at a higher position of the first guide surface 2411 (for example, the left side of the first guide surface 2411), and the axis of the sample container is approximately located in the vertical plane, as the stirring component 241 moves up and down, the sample container will slide along the first guide surface 2411 to a lower position (for example, the right side of the first guide surface 2411) under the action of gravity, and the sample container as a whole will also tip over, that is, the axis of the sample container is no longer located in the vertical plane. In this way, when the sample container is tipped to a certain angle, the sample cover will separate from the first guide surface 2411 under the action of gravity.

[0079] Along the direction from the second side to the first side, the distance between the second guide surface 2412 and the bottom wall 211 of the bin decreases. For example, the first guide surface 2411 may be an inclined surface or an arc surface, and the working mode of the second guide surface 2412 may be understood with reference to the first guide surface 2411.

[0080] By providing the first guide surface 2411 and the second guide surface 2412 , the problem of sample container retention can be effectively improved no matter the sample container is hung on the first side or the second side of the stirring component 241 .

[0081] When the guide portion includes the first guide surface 2411 and the second guide surface 2412, in some embodiments of the present invention, Fig. 9 The first guide surface 2411 extends to the first side away from one end of the second guide surface 2412, for example, the left end of the first guide surface 2411 extends to the left side of the stirring member 241; the second guide surface 2412 extends to the second side away from one end of the first guide surface 2411, for example, the right end of the second guide surface 2412 extends to the right side of the stirring member 241. In this way, it is possible to avoid forming a plane that is easy to hang between the first guide surface 2411 and the left side of the stirring member 241, and between the second guide surface 2412 and the right side of the stirring member 241.

[0082] When the guide portion includes the first guide surface 2411 and the second guide surface 2412, in some embodiments of the present invention, Fig. 9 , an end of the first guide surface 2411 away from the second guide surface 2412 and an end of the second guide surface 2412 away from the first guide surface 2411 intersect, thereby avoiding the formation of a plane that is easy to hang between the first guide surface 2411 and the second guide surface 2412.

[0083] It should be noted that, in some specific embodiments, when the stirring member 241 includes the first stirring portion 241a in the aforementioned embodiment, a first guide surface 2411 and a second guide surface 2412 may be provided on the top of the first stirring portion 241a to enhance the anti-standing function of the first stirring portion 241a. In other specific embodiments, when the stirring member 241 includes the second stirring portion 241b in the aforementioned embodiment, a first guide surface 2411 and a second guide surface 2412 may be provided on the top of the second stirring portion 241b to enhance the anti-standing function of the second stirring portion 241b.

[0084] When the stirring member 241 moves in the up and down direction to stir the sample container, in some embodiments of the present invention, Figure 6 The loading component 200 also includes a storage chamber 250 disposed below the first material bin 210. The bottom wall 211 of the first material bin 210 has a through groove 2111 connected to the storage chamber 250. The stirring member 241 is configured to move downward relative to the bin bottom wall 211 so as to be retracted into the storage chamber 250 through the through groove 2111, and to move upward relative to the bin bottom wall 211 so as to extend into the first material bin 210 through the through groove 2111. In this way, when the stirring member 241 is in a retracted state, it will not occupy the space in the first material bin 210, thereby not hindering the flow of the sample container to the feeding mechanism 230.

[0085] It should be noted that, when the stirring member 241 includes the first stirring portion 241a and the second stirring portion 241b, the bin bottom wall 211 is correspondingly provided with two through grooves 2111, and the width of the through grooves 2111 is slightly wider than the corresponding stirring portion.

[0086] It should also be noted that the storage cavity 250 may be defined by an independent storage body, or by components such as the first shell 110 .

[0087] When the stirring member 241 moves relative to the bottom wall of the bin to stir the sample container, in some embodiments of the utility model, the feeding mechanism 230 includes a fixed member, a movable member and a second driving member 233, the fixed member is connected to the first bin 210, the movable member is movably connected to the fixed member, and can be driven by the second driving member to move relative to the fixed member to transport a single sample container. In some specific embodiments, the first driving member and the second driving member are the same driving member, so that the feeding mechanism 230 can be driven to complete feeding and the stirring mechanism 240 can be driven to complete stirring by one driving member.

[0088] In some embodiments, the feeding mechanism 230 may be a chain plate feeding mechanism, which includes a frame as a fixed component and a conveyor belt as a movable component. The conveyor belt is annular and arranged on the frame. A plurality of raised conveyor plates are arranged on the outer side of the conveyor belt. The length of the conveyor plate is greater than the length of the sample container, and the spacing between adjacent conveyor plates is greater than the diameter of the sample container. Thus, a transfer space for accommodating the sample container is formed between adjacent conveyor plates. With the driving of the second driving component, the conveyor belt rotates, thereby driving the sample container to be lifted upward. After being lifted to the highest point, the sample container will fall onto the transfer assembly 300 under the action of gravity. In some embodiments, the bottom wall 211 of the first material bin 210 is inclined toward the feeding mechanism 230, so that the sample container can be close to the conveyor belt of the feeding mechanism 230 under the action of gravity. The conveyor belt of the feeding mechanism 230 can be inclined, and the lowest point of the conveyor belt is lower than the lowest point of the bin bottom wall 211, so that the sample container at the bottom of the first material bin 210 can also enter the transfer space of the feeding mechanism 230.

[0089] In some embodiments, reference Figure 6 , Fig. 9 The feeding mechanism 230 may also be a push-plate feeding mechanism, which includes at least one first feeding component, each of which includes a single fixed plate 231 and a single movable plate 232. In the same first feeding component, the movable plate 232 and the fixed plate 231 are arranged side by side, and the two are parallel, for example, they are arranged side by side along the direction from the first material bin 210 to the feeding mechanism 230, and the movable plate 232 is closer to the first material bin 210 than the fixed plate 231. The fixed plate 231 is fixedly arranged relative to the first material bin 210, and the second driving component is connected to the movable plate 232, and is used to drive the movable plate 232 to reciprocate between the first position and the second position relative to the fixed plate 231, wherein when the movable plate 232 is located at the first position, the top of the movable plate 232 is lower than the top of the fixed plate 231, and the top of the movable plate 232 can receive a single sample container; when the movable plate 232 is located at the second position, the top of the movable plate 232 is not lower than the top of the fixed plate 231, and the single sample container is transferred from the top of the movable plate 232 to the top of the fixed plate 231, so that as the movable plate 232 reciprocates, a single sample container can be sorted and lifted.

[0090] Typically, the feeding mechanism 230 includes a plurality of first feeding components, thereby increasing the lifting range of the feeding mechanism 230, thereby enabling the first silo 210 to have a sufficient depth and increasing the capacity of the first silo 210. For example, the feeding mechanism 230 includes three first feeding components, each of the fixed plates 231 in the three first feeding components constitutes the aforementioned fixed component, and each of the movable plates 232 constitutes the aforementioned movable component. The three first feeding components are arranged in a direction away from the stirring mechanism 240 and close to the stirring mechanism 240, that is, a plurality of fixed plates 231 and a plurality of movable plates 232 are arranged in sequence, and the top surfaces of the fixed plates 231 at each level are lowered in sequence. The first feeding component located in the middle is used as an example to illustrate that when the movable plate 232 moves to the first position, its top end is not higher than the top end of the fixed plate 231 of the first feeding component adjacent to and closer to the stirring component 241, and when the movable plate 232 moves to the second position, its top end is not lower than the top end of the fixed plate 231 of the same feeding component; the first feeding component closest to the stirring component 241 is used as an example to illustrate that when the movable plate 232 moves to the first position, its top end is not higher than the bin bottom wall 211, and when the movable plate 232 moves to the second position, its top end is not lower than the top end of the fixed plate 231 of the same feeding component. Specifically, Figure 6 , Fig. 9 In the illustrated embodiment, along the direction away from the stirring mechanism 240 to the direction close to the stirring mechanism 240, that is, from left to right in the figure, each fixed plate 231 is named as a first-stage fixed plate 231, a second-stage fixed plate 231 and a third-stage fixed plate 231, and each movable plate 232 is named as a first-stage movable plate 232, a second-stage movable plate 232 and a third-stage movable plate 232. When the third-stage movable plate 232 is located at the first position, it is lower than the bottom wall 211 of the first bin 210, so that the sample container can roll to the top of the third-stage movable plate 232, and then when the third-stage movable plate 232 moves upward to the second position, its level When the second movable plate 232 is at the first position, it is lower than the top of the third fixed plate 231, so that the sample container can roll to the top of the second movable plate 232, and then when the second movable plate 232 moves upward to the second position, it is flush with the top of the second fixed plate 231, and the sample container automatically rolls to the top of the second fixed plate 231. According to this understanding, a single sample container can be finally transported to the top of the first fixed plate 231 and fall from the top of the first fixed plate 231 to the transfer assembly 300. In some embodiments, the bottom wall 211 of the first bin 210 is inclined toward the feeding mechanism 230, so that the sample container can lean against the movable plate 232 of the feeding mechanism 230 under the action of gravity.

[0091] In some specific embodiments, the movable plates 232 are fixedly connected to each other so that they can be driven uniformly by the second driving component. Fig. 9 The stirring mechanism 240 can be fixedly connected to each movable plate 232, so that when the second driving component drives the movable plate 232 to move relative to the fixed plate 231, it can also synchronously drive the stirring mechanism 240 to move up and down relative to the bin bottom wall 211.

[0092] When the feeding mechanism 230 includes a first feeding component, in some embodiments of the present invention, the feeding mechanism 230 may also include a second feeding component, and the second feeding component includes a single fixed plate 231 or a single movable plate 232. When the second feeding component includes a single fixed plate 231, the fixed plate 231 can be used as the highest-level fixed plate or the lowest-level fixed plate of the entire feeding mechanism 230. When the second feeding component includes a single movable plate 232, the movable plate 232 can be used as the highest-level movable plate or the lowest-level movable plate of the entire feeding mechanism 230.

[0093] As mentioned above, since the volume of the first material bin 210 is limited, if a large number of sample containers enter the first material bin 210 in a short period of time, blockage will occur. Based on this, in some embodiments of the present invention, referring to Figures 4 to 8 The loading component 200 also includes a flow limiting mechanism 260. When the sample container flows into the first bin 210, for example, from the second bin 220 into the first bin 210, the flow limiting mechanism 260 is configured to limit the flux of the sample containers flowing into the storage space. In this way, even if a large number of sample containers are introduced into the second bin 220 in a short period of time, they will be limited by the flow limiting mechanism 260, so that they gradually enter the first bin 210 over a relatively long period of time, thereby improving the problem of sample containers being blocked in the first bin 210.

[0094] When the sample loading assembly 200 further includes a flow limiting mechanism 260, in some embodiments of the present invention, Figure 6 , the flow limiting mechanism 260 is used to define a transmission channel 261 for transmitting sample containers, and the transmission channel 261 is configured to gradually shrink toward the storage space along the inflow direction of the sample container, so that the flux of the sample container output by the transmission channel 261 is less than the flux of the sample container input, thereby realizing the flow limiting function. It should be noted that the "transmission channel 261 for defining the transmission sample container" referred to herein includes both a solution in which the flow limiting mechanism 260 itself can define the transmission channel 261, and a solution in which the flow limiting mechanism 260 and other mechanisms jointly define the transmission channel 261. In addition, it should also be noted that this embodiment does not limit the setting position of the flow limiting mechanism 260, which can be located inside the first material bin 210 or outside the first material bin 210, which will be explained in subsequent embodiments.

[0095] When the flow limiting mechanism 260 is used to define a transmission channel 261 for transmitting a sample container, in some embodiments of the present invention, Figures 4 to 8 The side wall 212 is provided with a first opening 2121 for allowing sample containers to flow from the second bin 220 into the first bin 210, wherein the first opening 2121 is a shape suitable for batch sample containers to pass through and convenient for processing, such as a rectangular shape as shown in the figure. The first opening 2121 can be provided on any side of the side wall 212, such as Figure 6 The side shown is facing the feeding mechanism 230.

[0096] The flow limiting mechanism 260 includes a flow limiting component 262 that at least partially extends into the storage space. In this embodiment, the transmission channel 261 is formed between the extending portion of the flow limiting component 262 and the corresponding structure of the first silo 210. In other words, the transmission channel 261 of this embodiment is at least partially located inside the first silo 210. Figures 6 to 8 As shown, the transmission channel 261 includes a guide space 261a located between the protruding portion of the flow-limiting component 262 and the first opening 2121, the guide space 261a is connected to the first opening 2121, and the guide space 261a is at least open toward the bottom wall 211. When the sample container flows into the first material bin 210, it will first pass through the guide space 261a. If there are a large number of sample containers in the first material bin 210 at this time, the newly entered sample containers will be temporarily retained in the guide space 261a due to accumulation. However, since the guide space 261a is open toward the bottom wall 211, it is in an unstable state. When the number of sample containers below decreases (for example, when the sample containers are transferred to the feeding mechanism 230 through the stirring of the stirring mechanism 240), the sample containers in the guide space 261a will automatically fall under the action of gravity. Therefore, the flow-limiting component 262 of this embodiment can not only limit the flow, but also play a certain guiding role, which can prevent the sample containers from being blocked in the transmission channel 261 due to the tapered setting of the transmission channel 261.

[0097] It should be noted that, in addition to being open toward the bin bottom wall 211, the guide space 261a can also be opened toward the bin side wall. Figure 4 For example, when the front side and / or rear side of the flow limiting component 262 does not extend to the side plate on the corresponding side of the bin side wall 212, the front side and / or rear side of the guide space 261a are also open, which can eliminate the restriction of the flow limiting component 262 on the sample container along the front and rear directions, making it easier for the sample container to escape from the guide space 261a.

[0098] In some specific embodiments, the distance between the flow-limiting component 262 and the first opening 2121 increases in the direction toward the bottom wall 211 of the chamber, that is, the width of the guide space 261a increases. In other words, a local area that directly flows with the first opening 2121 and has a gradually increasing width is formed in the overall tapered transmission channel 261, thereby further strengthening the guiding effect, preventing the flow-limiting component 262 from hindering the downward movement of the sample container, and further preventing blockage in the transmission channel 261. Figure 6 As shown in the example, the flow limiting component 262 is a flow limiting plate, which is arranged to be inclined as a whole, so as to form a guide space 261a whose width gradually increases. In other specific embodiments, the flow limiting component 262 can be a flow limiting seat, which is provided with an inclined flow limiting surface on the side facing the first opening 2121, and the flow limiting surface and the first opening 2121 form a guide space 261a.

[0099] When the flow limiting mechanism 260 includes the aforementioned flow limiting component 262 at least partially extending into the first material bin 210, in some embodiments of the present invention, Figures 4 to 8 , the flow limiting component 262 is arranged on the upper side of the first opening 2121 and extends obliquely toward the bin bottom wall 211. The flow limiting component 262, the bin side wall 212 and the bin bottom wall 211 jointly define the transmission channel 261. Usually, in order to facilitate the user to pour, the height of the second bin 220 is higher than the height of the first bin 210, so the sample container will flow into the first bin 210 from a high place. In this embodiment, the flow limiting component 262 is arranged on the upper side of the first opening 2121, which can play a better flow limiting function for the sample container flowing downward.

[0100] The above describes a scheme in which the transmission channel 261 is arranged inside the first silo 210. In other embodiments, the transmission channel 261 may also be arranged outside the first silo 210. Specifically, the flow limiting mechanism 260 is arranged outside the silo side wall 212. The transmission channel 261 is defined inside the flow limiting mechanism 260. The two ends of the transmission channel 261 are respectively connected to the first silo 210 and the second silo 220. For example, Figure 2 The connecting component 270 is used as the flow limiting mechanism 260.

[0101] It should be noted that the flow limiting mechanism 260 is arranged on the outside of the bin side wall 212 , which may include a solution in which the flow limiting mechanism 260 is arranged inside the second shell 120 , or a solution in which the flow limiting mechanism 260 is arranged between the first shell 110 and the second shell 120 .

[0102] When the current limiting mechanism 260 defines the transmission channel 261, in some embodiments of the present invention, Fig.10The flow limiting mechanism 260 includes an adjusting component 263, and the flow limiting mechanism 260 is configured to adjust the extension length of the transmission channel 261 along the inflow direction of the sample container through the adjusting component 263, and / or, adjust the outlet size of the transmission channel 261 through the adjusting component 263, thereby adjusting the flow limiting capacity of the flow limiting mechanism 260.

[0103] In some embodiments, when the flow limiting mechanism 260 includes a flow limiting component 262 that at least partially extends into the storage space, Fig.10 The flow limiting component 262 is connected to the first material bin 210 through the adjusting component 263, wherein the flow limiting component 262 is configured to move relative to the first material bin 210 through the adjusting component 263 to adjust the distance between the free end of the flow limiting component 262 and the first opening 2121, thereby adjusting the extension length of the transmission channel 261 along the inflow direction of the sample container, and / or, the flow limiting component 262 is configured to rotate relative to the first material bin 210 through the adjusting component 263 to adjust the inclination angle of the flow limiting component 262 relative to the first opening 2121, thereby adjusting the outlet size of the transmission channel 261.

[0104] In some specific embodiments, referring to Fig.10 The adjusting component 263 can simultaneously realize the adjustment of the extension length of the transmission channel 261 and the adjustment of the opening, and specifically includes a first adjusting part 2631, a second adjusting part 2632, a first locking part 2633 and a second locking part 2634. The first adjusting part 2631 is connected to the first silo 210, the second adjusting part 2632 is movably connected to the first adjusting part 2631, the flow limiting part 262 is movably connected to the second adjusting part 2632, the first locking part 2633 locks the first adjusting part 2631 and the second adjusting part 2632, and the second locking part 2634 locks the flow limiting part 262 and the second adjusting part 2632. Among them, when the first locking part 2633 is unlocked, the second adjusting part 2632 can drive the flow limiting part 262 to rotate relative to the first adjusting part 2631 to adjust the outlet size of the transmission channel 261, and, when the second locking part 2634 is unlocked, the flow limiting part 262 can move relative to the second adjusting part 2632 to adjust the extension length of the transmission channel 261 along the inflow direction of the sample container.

[0105] Specifically in the illustrated embodiment, the first adjusting portion 2631 and the second adjusting portion 2632 are plate-like structures, and the first locking component 2633 and the second locking component 2634 are threaded fasteners. The first adjusting portion 2631 includes a first base plate and a first connecting plate connected to the first base plate, and the second adjusting portion 2632 includes a second base plate and a second connecting plate connected to the second base plate, one of the first connecting plate and the second connecting plate is provided with an arc groove, and the other is provided with a first hole, and the first locking component 2633 is penetrated in the first hole and extends into the arc groove, so that when the first locking component 2633 slides in the groove, the first adjusting portion 2631 and the second adjusting portion 2632 can rotate relative to each other. In addition, one of the first base plate and the current limiting component 262 is provided with a linear groove, and the other is provided with a second hole, and the second locking component 2634 is penetrated in the first hole and extends into the linear groove, so that when the second locking component 2634 slides in the groove, the second adjusting portion 2632 and the current limiting component 262 can move relative to each other.

[0106] 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.
