[0040] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0041] The following is combined Figures 1-4 The sampling components and sample retrieval device provided in the utility model embodiments will be described in detail through specific implementation examples and application scenarios.

[0042] In the first aspect, such as Figure 1 and Figure 2 As shown, this utility model embodiment provides a sampling component, including: a movable base 1, a telescopic frame 2, a locking component 3, and a sampling hose 4;

[0043] The mobile seat 1 is configured to be mounted on the sampling vehicle 7;

[0044] The telescopic frame 2 includes multiple frame sections 21, which are connected sequentially from top to bottom. Adjacent frame sections 21 slide in a vertical direction. The top section of the multiple frame sections 21 is set at a predetermined position on the movable seat 1.

[0045] The locking assembly 3 includes a locking member 31 and a lever mechanism 32. The locking member 31 and the lever mechanism 32 are respectively disposed on the movable seat 1. The locking member 31 is located on one side of the set position. The lever mechanism 32 is used to move the frame 21 located below the set position to the set position. The locking member 31 is used to lock the frame 21 moved by the lever mechanism 32.

[0046] The sampling hose 4 is configured to communicate with the negative pressure container, and extends at least partially along the extension direction of the telescopic frame 2, reaching the bottom end of the telescopic frame 2.

[0047] Understandably, the sampling vehicle 7 is used to move the mobile seat 1 so that the port of the sampling hose 4 at the bottom of the telescopic frame 2 can be set vertically opposite to the opening of the milk tanker.

[0048] The sampling hose 4 can be made of silicone or plastic. The lower end of the sampling hose 4 is the sampling end, which is located at the bottom of the telescopic frame 2. The upper end of the sampling hose 4 is connected to the negative pressure container. Under the negative pressure in the negative pressure container, the sampling end of the sampling hose 4 can draw raw milk from the milk tanker. The raw milk flows along the sampling hose 4 to the negative pressure container until it is collected in the negative pressure container.

[0049] The telescopic frame 2 is equipped with at least two frame sections 21. Depending on the model of the milk tanker, it can ensure the height of the tank opening of the milk tanker from the ground. This allows the locking part 31 and the lever mechanism 32 to cooperate to adjust the telescopic length of the telescopic frame 2, so that the port of the sampling hose 4 at the bottom of the telescopic frame 2 can be inserted into the tank opening of the milk tanker.

[0050] Taking a telescopic frame 2 with three sections 21 as an example, if it is necessary to control the telescopic frame 2 to retract, the lever mechanism 32 can be connected to the second section 21 in the vertical direction, and the section 21 can be moved upward until it moves to the set position. Then, the locking member 31 is locked to the section 21 moved by the lever mechanism 32. At this time, the section 21 locked by the locking member 31 overlaps with the original top section 21 of the telescopic frame 2, so the length of the telescopic frame 2 is shortened and becomes the length of two sections 21.

[0051] By following this operation, the third vertically arranged frame 21 can be moved upwards. When the frame 21 is moved to the set position, it is locked by the locking piece 31. The length of the telescopic frame 2 continues to shorten and becomes the length of one frame 21.

[0052] Correspondingly, if it is necessary to control the extension of the telescopic frame 2, the operation sequence can be reversed as described above. First, control the locking member 31 to release the lock on the frame 21, and then control the frame 21 to move downward by the lever mechanism 32. Each frame 21 can be controlled to move downward in sequence until the telescopic frame 2 returns to the length of two or three frames 21.

[0053] As can be seen from the above, the sampling assembly shown in this utility model, by setting up a movable seat 1, a telescopic frame 2, a locking assembly 3, and a sampling hose 4, can adjust the coordination state between different frames 21 of the telescopic frame 2 by utilizing the mutual cooperation of the locking part 31 of the locking assembly 3 and the lever mechanism 32, thereby realizing the length adjustment of the telescopic frame 2. Since at least part of the sampling hose 4 extends along the extension direction of the telescopic frame 2 and reaches the bottom end of the telescopic frame 2, the position of the sampling end of the sampling hose 4 relative to the mouth of the milk tanker can be adjusted by using the telescopic frame 2, which can conveniently sample raw milk from milk tankers of different sizes. Compared with manual sampling, this design improves the efficiency of raw milk sampling.

[0054] In some embodiments, such as Figure 1 and Figure 2 As shown, the locking member 31 includes a first telescopic member and a first fork; the first telescopic member is disposed on the movable seat 1, the telescopic end of the first telescopic member is connected to the first fork, and the first fork is used to be inserted into the frame 21 and to achieve a locking connection with the frame 21.

[0055] Understandably, the first telescopic member can be a cylinder, and the first telescopic member can be configured to be horizontal and located at the upper end of the top one of the multi-section frame 21.

[0056] The first telescopic member has an extended state and a retracted state. When it is necessary to lock the frame 21, the first telescopic member is in the extended state and the first fork is inserted into the frame 21. When it is not necessary to lock the frame 21, the first telescopic member is in the retracted state and the first fork is separated from the frame 21.

[0057] In some embodiments, such as Figure 1 As shown, the lever mechanism 32 includes a lifting drive 321 and a locking member 322. The lifting drive 321 is located on the movable seat 1 and connected to the locking member 322. The lifting drive 321 is used to drive the locking member 322 to move up and down in the vertical direction. The locking member 322 is used to connect to the frame 21 so that the frame 21 can be moved up and down under the drive of the lifting drive 321.

[0058] Understandably, the lifting drive component 321 can be a telescopic component or a screw lifting mechanism; the locking component 322 can be a telescopic rod or a gripper; wherein, the telescopic rod can be inserted into the frame 21 to achieve connection with the frame 21; the gripper can clamp the frame 21 to achieve connection with the frame 21.

[0059] The lifting drive 321 and the locking member 322 are connected to control the locking member 322 to switch between a first height position and a second height position, wherein the first height position is lower than the second height position.

[0060] When the telescopic frame 2 is retracted, the lifting drive 321 controls the locking member 322 to be in the first height position. The locking member 322 is connected to the frame 21 on the lower side in the set position. The lifting drive 321 controls the locking member 322 to rise from the first height position to the second height position. After the locking member 31 is locked to the frame 21 moved by the lever mechanism 32, the locking member 322 is separated from the frame 21.

[0061] Accordingly, when the telescopic frame 2 is extended, the lifting drive 321 controls the locking member 322 to be in the second height position. The locking member 322 is connected to the frame 21 which is folded in the set position. After the locking member 31 is released from the locking connection with the frame 21, the lifting drive 321 controls the locking member 322 to descend from the second height position to the first height position, and then controls the locking member 322 to separate from the frame 21.

[0062] In some embodiments, such as Figure 1 As shown, the lifting drive component 321 includes a drive motor 3211, a belt 3212 and multiple pulleys 3213; the drive motor 3211 and multiple pulleys 3213 are respectively disposed on the movable seat 1, the drive motor 3211 and the belt 3212 are connected, and the belt 3212 is wound between the multiple pulleys 3213.

[0063] The locking element 322 slides in a vertical direction with the movable seat 1, and at least a portion of the belt 3212 extends vertically and is connected to the locking element 322.

[0064] Specifically, the movable seat 1 is provided with a slide rail extending in the vertical direction, and the locking member 322 is movably disposed on the slide rail in the vertical direction so as to realize the sliding engagement of the locking member 322 with the movable seat 1 in the vertical direction.

[0065] Meanwhile, the output end of the drive motor 3211 is provided with a wheel, and the drive motor 3211 is connected to the belt 3212 through the wheel; there are at least two pulleys 3213, which are arranged in a vertically opposite manner. When the belt 3212 is wound around multiple pulleys 3213, this arrangement ensures that at least part of the belt 3212 is located on one side of the slide rail and extends in the vertical direction.

[0066] In practical applications, by controlling the forward and reverse rotation of the drive motor 3211, the drive motor 3211 can drive the belt 3212 to move in different directions, and the belt 3212 can then drive the locking member 322 to move up and down relative to the moving seat 1 in the vertical direction.

[0067] In some embodiments, such as Figure 1As shown, the locking member 322 includes a second telescopic member and a second fork; the lifting drive member 321 is connected to the second telescopic member, the telescopic end of the second telescopic member is connected to the second fork, and the second fork is used to be inserted into the frame 21 and to achieve a locking connection with the frame 21.

[0068] Understandably, the second telescopic member may be a cylinder, and the second telescopic member is configured to be horizontal and located at the lower end of the one at the top of the multi-section frame 21.

[0069] The second telescopic member has an extended state and a retracted state. When it is necessary to lock the frame 21, the second telescopic member is in the extended state and the second fork is inserted into the frame 21. When it is not necessary to lock the frame 21, the second telescopic member is in the retracted state and the second fork is separated from the frame 21.

[0070] In some embodiments, such as Figure 1 As shown, the frame 21 includes a first connecting seat 211, a second connecting seat 212, and a connecting rod 213; the first connecting seat 211 is located at the upper end of the connecting rod 213, and the second connecting seat 212 is located at the lower end of the connecting rod 213.

[0071] For two adjacent frame sections 21, the connecting rod 213 of the upper frame section 21 passes through the first connecting seat 211 of the lower frame section 21, and the locking member 31 and the lever mechanism 32 are both configured to be connected to the first connecting seat 211.

[0072] In practical applications, when the locking member 31 includes the first telescopic member and the first fork, if the locking member 31 is locked to the frame 21, the first telescopic member can be controlled to be in the extended state so that the first fork is located on the lower side of the first connecting seat 211 and abuts against the first connecting seat 211 from top to bottom.

[0073] Accordingly, if the locking member 322 of the lever mechanism 32 includes a second telescopic member and a second fork, and the locking member 322 is used to lock the connection with the frame 21, the second telescopic member can be controlled to be in the extended state so that the second fork is located on the lower side of the first connecting seat 211 and abuts against the first connecting seat 211 from top to bottom.

[0074] For example, two connecting rods 213 can be provided, with the two connecting rods 213 arranged side by side.

[0075] In some embodiments, such as Figure 1 As shown, in order to simplify the layout of the sampling hose 4, one of the multi-section frame 21 at the bottom is configured as a material delivery tube. The lower end of the material delivery tube is used to insert into the sample, and the upper end of the material delivery tube is connected to the sampling hose 4.

[0076] In some embodiments, such as Figure 1As shown, the bottom of the telescopic frame 2 is provided with at least one of a retrieval net 5 and a thermometer 6.

[0077] Specifically, the bottom of the telescopic frame 2 is equipped with a retrieval net 5 and a thermometer 6, with the retrieval net 5 set with its opening facing upwards.

[0078] When sampling raw milk, thermometer 6 is used to detect the temperature of the raw milk. A retrieval net 5 is used to retrieve clumps or foreign objects floating on the surface of the raw milk. If the retrieval net 5 retrieves clumps or foreign objects, the raw milk is deemed unqualified.

[0079] In the second aspect, such as Figure 3 and Figure 4 As shown, this utility model embodiment also provides a sample retrieval device, including: a sampling vehicle 7 and the sampling components described above;

[0080] The sampling vehicle 7 is movable along the first direction, and the movable seat 1 is movably mounted on the sampling vehicle 7 along the second direction, with the first and second directions being perpendicular.

[0081] Understandably, since the sampling vehicle 7 is movable along the first direction, the movable seat 1 is movable along the second direction, and the telescopic frame 2 can extend and retract in the vertical direction, the telescopic frame 2 can drive the sampling end of the sampling hose 4 to different positions in the three-dimensional space. Thus, the port of the sampling hose 4 located at the bottom of the telescopic frame 2 can reach the opening of the tank of different sizes of milk tank trucks, ensuring the feasibility of the sampling operation.

[0082] Since the sample retrieval device includes a sampling component, and the specific structure of the sampling component is as described in the above embodiments, the sample retrieval device of this embodiment includes all the technical solutions of the above embodiments. Therefore, it has at least all the beneficial effects achieved by all the technical solutions of the above embodiments, which will not be described in detail here.

[0083] In some embodiments, such as Figure 3 and Figure 4 As shown, the sampling vehicle 7 includes a main body 71, a crossbeam 72 and a transverse drive module 73; the main body 71 is movable along a first direction and connected to one end of the crossbeam 72, and the crossbeam 72 extends along a second direction.

[0084] A transverse drive module 73 is disposed on the crossbeam 72 and connected to the movable seat 1. The transverse drive module 73 is used to drive the movable seat 1 to move along the extension direction of the crossbeam 72.

[0085] Specifically, the main body 71 has two legs arranged side by side, each leg corresponding to one of the two track grooves, and can move along the extension direction of the track grooves.

[0086] The main vehicle body 71 is equipped with a braking assembly 74, which can abut against the track groove to limit the position of the sampling vehicle 7 relative to the track groove.

[0087] For example, the brake assembly 74 includes a telescopic drive member, a pressure rod, and a polyurethane brake block. The middle portion of the pressure rod is rotatably mounted on the main vehicle body 71. One end of the telescopic drive member is rotatably connected to the main vehicle body 71, and the other end is rotatably connected to the first end of the pressure rod. The second end of the pressure rod is connected to the polyurethane brake block. The telescopic drive member controls the rotation of the pressure rod relative to the main vehicle body 71 through telescopic movement, thereby causing the pressure rod to abut or separate from the track groove.

[0088] To ensure the stability of the crossbeam 72 installation, an oblique support is provided between the main body 71 and the crossbeam 72; the lateral drive module 73 is located on the top of the crossbeam 72. The lateral drive module 73 can be a linear slide module known in the art. The slide of the linear slide module is connected to the moving seat 1 of the sampling component to drive the sampling component to move horizontally in the second direction.

[0089] In addition, a control cabinet 8 is also provided on the main body 71. The control cabinet 8 is equipped with a control module and operation buttons and a touch screen that are electrically connected to the control module. The control module is electrically connected to the lateral drive module 73 and the locking component 3 respectively. For example, the control module can be a microcontroller or a PLC controller. The control module is electrically connected to the lateral drive module 73, the locking component 31, the lifting drive component 321 and the locking component 322 respectively.

[0090] In practical applications, staff can input control commands via a touchscreen. The control module responds to the control commands and controls the working status of the lateral drive module 73 and the locking component 3, thereby enabling the sampling of raw milk based on the sampling component.

[0091] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
