In this specification, the schematic descriptions of the above terms do not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials, or characteristics described can be combined in a suitable manner in any one or more embodiments or examples.

[0032] Please refer to Figures 1 to 2 , the embodiment of the present application provides a sample mixing device 100, and the sample mixing device 100 can be used to mix a variety of materials to obtain the required mixed materials. For example, the sample mixing device 100 can mix a variety of materials to obtain cement with the required ratio.

[0033] The sample mixing device 100 includes a base 110, a cylinder 130, a stirring member 150, and a connecting member 170.

[0034] Among them, the base 110 can be used to support the cylinder 130, the stirring member 150, the connecting member 170, and other structural members.

[0035] The base 110 can serve as a counterweight structure to prevent the sample mixing device 100 from tipping over.

[0036] The shape of the base 110 can be set according to requirements. For example, the base 110 can adopt a columnar solid structure, a frame structure, a support rod, or a structure with other shapes. For the support rod, a counterweight block can be provided at the bottom of the support rod to prevent the sample mixing device 100 from tipping over.

[0037] The stirring member 150 is arranged inside the cylinder 130, and the stirring member 150 is used to stir the materials inside the cylinder 130, which helps to make the various materials inside the cylinder 130 mix more evenly.

[0038] The barrel 130 is rotatably connected to the base 110, so that the barrel 130 can be manually rotated without a complex driving structure, and the operation is more natural and flexible.

[0039] The barrel 130 is provided with a material port 1351 for feeding and discharging materials, so that a single material port 1351 can be shared during loading and unloading, simplifying the structure of the barrel 130. Moreover, by rotating the barrel 130, the position of the material port 1351 can be adjusted, making both loading and unloading more convenient.

[0040] The connecting member 170 has a first state (as shown in Figure 1 ) and a second state (as shown in Figure 2 and Figure 3 ). When the connecting member 170 is in the first state, the connecting member 170 is connected between the barrel 130 and the base 110 to fix the barrel 130 to the base 110, so that the barrel 130 is in a fixed state and the stirring member 150 can stably stir the materials.

[0041] When the connecting member 170 is in the second state, the barrel 130 can rotate relative to the base 110 to adjust the position of the material port 1351. Thus, the barrel 130 can be manually rotated to adjust the position of the material port 1351 without a complex driving structure to drive the rotation of the barrel 130. For scenarios with a small mixing sample size (such as during experiments), users (such as laboratory technicians) can freely and flexibly manually operate the barrel 130, making the operation more convenient and enhancing the flexibility of the mixing device 100.

[0042] Among them, when the connecting member 170 is in the second state, the connecting member 170 can be arranged in various ways.

[0043] As an example, when the connecting member 170 switches to the second state, the connecting member 170 can still be connected between the barrel 130 and the base 110. At this time, the connecting member 170 and the barrel 130 can be switched to a rotatable connection, and the barrel 130 can rotate relative to the connecting member 170; or the connecting member 170 and the base 110 can be switched to a rotatable connection, and the barrel 130 and the connecting member 170 can rotate synchronously relative to the base 110.

[0044] As another example, the connecting member 170 can include two connected structural members, one of which is connected to the base 110 and the other is connected to the barrel 130. When the connecting member 170 is in the first state, the two structural members are fixedly connected. When the connecting member 170 switches to the second state, the two structural members can be rotatably connected, so that the barrel 130 can rotate relative to the base 110.

[0045] As another example, the connecting member 170 can also be detached from the cartridge 130 or the base 110. The cartridge 130 and the base 110 can be connected by other rotating structures. The cartridge 130 can rotate around the rotating structure, or the cartridge 130 and the rotating structure can rotate relative to the base 110 synchronously.

[0046] Understandably, the connecting member 170 can also be connected or detachably connected between the cartridge 130 and the base in other ways to freely switch between the first state and the second state.

[0047] During the actual operation of the sample mixing device 100, as an example, when loading is required, the connecting member 170 can be adjusted to the second state. The user can hold the cartridge 130 and rotate the cartridge 130 to make the material inlet 1351 face the desired position (such as the material inlet 1351 facing upward or facing the user), so that the material to be mixed can be conveniently loaded into the cartridge 130 through the material inlet 1351.

[0048] During the loading process, to maintain the stability of the cartridge 130, the user can hold the cartridge 130 to fix the cartridge 130, or the connecting member 170 can be adjusted to the first state to fix the cartridge 130.

[0049] After the loading is completed, the connecting member 170 can be adjusted to the second state. The user can rotate the cartridge 130 to make the material inlet 1351 face downward, which is convenient for subsequent unloading. Understandably, the material inlet 1351 can be closed by a sealing structure at this time to prevent material leakage; the cartridge 130 can also not rotate, and the orientation of the material inlet 1351 can be maintained in the state during loading. After determining the position of the material inlet 1351, the connecting member 170 is adjusted to the first state to fix the cartridge 130. After the cartridge 130 is fixed, the stirring member 150 starts to stir the material.

[0050] After the material stirring is completed, if the material inlet 1351 faces downward at this time, the sealing structure can be removed to start unloading; if the material inlet 1351 faces other directions at this time, the connecting member 170 can be adjusted to the second state, and then the cartridge 130 is rotated to make the material inlet 1351 face downward or the desired direction for unloading. Understandably, during unloading, the connecting member 170 can be adjusted to the first state to fix the cartridge 130, so that unloading can be carried out stably, or the connecting member 170 can also remain in the second state. The user can hold the cartridge 130 to fix the cartridge 130, and unloading can also be carried out stably.

[0051] In some embodiments, the connecting member 170 may include a first connecting shaft 171 and a second connecting shaft 173 that are detachably connected. The first connecting shaft 171 may be connected to the base 110, and the second connecting shaft 173 may be connected to the cartridge 130. For example, the first connecting shaft 171 is detachably connected to the base 110, and the second connecting shaft 173 is detachably connected to the cartridge 130.

[0052] When the connecting member 170 is in the first state, the first connecting shaft 171 and the second connecting shaft 173 are fixedly connected, so that the cartridge 130 can be fixed to the base 110.

[0053] When the connecting member 170 is in the second state, the cartridge 130 can rotate about the axis of the second connecting shaft 173 to adjust the position of the material outlet 1351.

[0054] Wherein, when the connecting member 170 is in the second state, the first connecting shaft 171 can be fixedly connected to the base 110, and the second connecting shaft 173 can be connected between the cartridge 130 and the first connecting shaft 171 and rotatably connected to the first connecting shaft 171, that is, the cartridge 130 and the second connecting shaft 173 can rotate synchronously about the axis of the second connecting shaft 173.

[0055] As an example, the connecting member 170 may further include a connecting block, a first adjusting member, and a second adjusting member. The connecting block may be provided with a mounting through hole, a mounting through slot, a first adjusting hole, and a second adjusting hole.

[0056] Wherein, the axial direction of the mounting through hole may be parallel to the axial direction of the first connecting shaft 171 and penetrate through the connecting block, and the first connecting shaft 171 may be inserted into the mounting through hole. The first adjusting hole may communicate with the mounting through hole. The first adjusting hole may be a threaded hole, and the first adjusting member may be inserted into the first adjusting hole and provided with an external thread adapted to the internal thread of the first adjusting hole.

[0057] When the first adjusting member rotates, it can move along the axial direction of the first adjusting hole to abut against the first connecting shaft 171 or move away from the first connecting shaft 171. When the first adjusting member abuts against the first connecting shaft 171, the connecting block and the first connecting shaft 171 are fixedly connected; when the first adjusting member moves away from the first connecting shaft 171, the connecting block can move along the axial direction of the first connecting shaft 171 to facilitate the installation of the connecting block on the first connecting shaft 171 or the removal of the connecting block from the first connecting shaft 171.

[0058] The mounting through slot may penetrate through the connecting block along the horizontal direction X. When the connecting member 170 is in the first state, the second connecting shaft 173 may be located in the mounting through slot. The second adjusting hole may communicate with the mounting through slot. The second adjusting hole may be a threaded hole, and the second adjusting member may be inserted into the second adjusting hole and provided with an external thread adapted to the internal thread of the second adjusting hole.

[0059] Rotation of the second adjusting member can cause axial movement along the second adjusting hole to abut against the second connecting shaft 173 or move away from the second connecting shaft 173. When the second adjusting member abuts against the second connecting shaft 173, the second connecting shaft 173 is fixedly connected to the connecting block, the first connecting shaft 171 and the second connecting shaft 173 are fixed, the connecting member 170 is in the first state, and the cartridge 130 is fixed to the base 110; when the second adjusting member moves away from the second connecting shaft 173, the second connecting shaft 173 can rotate within the installation through slot, and the connecting member 170 is in the second state, so that the cartridge 130 and the second connecting shaft 173 can rotate synchronously about the axis of the second connecting shaft 173. Thus, rotating the second adjusting member can switch the connecting member 170 to the first state or the second state.

[0060] It can be understood that the notch of the installation through slot can be located on the side of the connecting block facing upward in the vertical direction Y, so that the connecting block can support the second connecting shaft 173.

[0061] In some embodiments, the sample mixing device 100 may further include a third connecting shaft 190, and the third connecting shaft 190 can be connected between the base 110 and the cartridge 130.

[0062] Wherein, when the connecting member 170 is in the first state and the third connecting shaft 190 is connected between the cartridge 130 and the base 110, at this time the connecting member 170 is also connected between the cartridge 130 and the base 110. The cooperation of the third connecting shaft 190 and the connecting member 170 can stably support the cartridge 130 at two positions, which helps the cartridge 130 to be more stably fixed to the base 110, reduces the shaking of the cartridge 130 when the sample mixing device 100 is operating, and reduces the noise.

[0063] When the connecting member 170 is in the second state, the third connecting shaft 190 is disengaged from at least one of the base 110 and the cartridge 130, so that the degree of freedom of the cartridge 130 can be released, and the cartridge 130 can rotate about the axis of the second connecting shaft 173.

[0064] Thus, by disassembling the third connecting shaft 190 from the base 110 and / or disassembling the third connecting shaft 190 from the cartridge 130, the degree of freedom of the cartridge 130 can be released. At this time, only the connecting member 170 supports the cartridge 130. Then, by rotating the second adjusting member to switch the connecting member 170 to the second state, the cartridge 130 can be freely rotated.

[0065] Please refer to Figure 1 and Figure 3 In some embodiments, when the connecting member 170 is in the second state, the first connecting shaft 171 is disengaged from the base 110 and / or the second connecting shaft 173 is disengaged from the cartridge 130 and / or the second connecting shaft 173 is disengaged from the first connecting shaft 171 (such as Figure 3As shown in the figure, that is, at least one of the states between the first connecting shaft 171 and the base 110, between the second connecting shaft 173 and the cartridge 130, and between the first connecting shaft 171 and the second connecting shaft 173 is in a state of being disengaged from each other, so that the degree of freedom of the cartridge 130 can be released. At this time, the connecting member 170 no longer supports the cartridge 130, and only the third connecting shaft 190 supports the cartridge, so that the cartridge 130 can rotate around the axis of the third connecting shaft 190.

[0066] Specifically, the first connecting shaft 171 is detached from the base 110, and / or the second connecting shaft 173 is detached from the cartridge 130, and / or the second connecting shaft 173 is detached from the first connecting shaft 171. At this time, the connecting member 170 switches to the second state, and the connecting member 170 no longer supports the cartridge 130. Only the third connecting shaft 190 supports the cartridge, and the cartridge 130 can rotate around the axis of the third connecting shaft 190.

[0067] In this embodiment, the connecting member 170 can be used as a fixing structure to fix the cartridge 130, and the third connecting shaft 190 can be used as a rotating structure. When the first connecting shaft 171 is disengaged from the base 110 and / or the second connecting shaft 173 is disengaged from the cartridge 130 and / or the first connecting shaft 171 is disengaged from the second connecting shaft 173, the connecting member 170 switches to the second state, and the connecting member 170 releases the degree of freedom of the cartridge 130. The cartridge 130 can rotate around the axis of the third connecting shaft 190. For example, the cartridge 130 and the third connecting shaft 190 can rotate around the axis of the third connecting shaft 190 synchronously.

[0068] The base 110 can adopt a support rod. The connection method between the third connecting shaft 190 and the support rod can refer to the connection method between the first connecting shaft 171 and the second connecting shaft 173 through the connecting block, the first adjusting member and the second adjusting member, which will not be elaborated here. In addition, the support rod can replace the first connecting shaft 171, and the second connecting shaft 173 and the third connecting shaft 190 can be directly connected to the support rod, so that the number of structural members of the mixing device 100 can be reduced.

[0069] In some embodiments, the first connecting shaft 171 and the base 110 can be detachably connected. For example, a threaded connection can be adopted between the first connecting shaft 171 and the base 110 to facilitate the detachment of the first connecting shaft 171 from the base 110.

[0070] As an example, a threaded hole can be provided on the base 110, and an external thread adapted to the threaded hole can be provided on the outer peripheral surface of the end of the first connecting shaft 171. The first connecting shaft 171 can be inserted into the threaded hole.

[0071] As another example, a threaded hole can be recessed on the end face of the first connecting shaft 171, and a threaded protrusion adapted to the threaded hole can be protruded on the base 110. The threaded protrusion can be inserted into the threaded hole.

[0072] Alternatively, a detachable connection can also be achieved between the first connecting shaft 171 and the base 110 through a fixing structure.

[0073] As an example, the sample mixing device 100 can further include a fixing plate. The fixing plate can be sleeved on the end of the first connecting shaft 171 and fixedly connected to the first connecting shaft 171. For example, the fixing plate and the first connecting shaft 171 can be welded or integrally formed. The fixing plate and the base 110 can be fixedly connected through a fixing member, so that the first connecting shaft 171 can be detachably connected to the base 110. Among them, the fixing member can be a screw, a rivet or other fixing structure.

[0074] It can be understood that the connection manner between the second connecting shaft 173 and the cartridge 130 and the connection manner between the third connecting shaft 190 and the cartridge 130 can both refer to the connection manner between the first connecting shaft 171 and the base 110, and will not be elaborated here.

[0075] In some embodiments, the cartridge 130 can be located on the side of the base 110, so as to reduce the overall height of the sample mixing device 100, which helps to control the cartridge 130 at a suitable height. The cartridge 130 can be closer to the placement plane (such as the ground) where the base 110 is located, facilitating the user to operate the cartridge 130 conveniently.

[0076] As an example, the third connecting shaft 190 can be connected between the outer side wall of the cartridge 130 and the outer side wall of the base 110, and the connecting member 170 can be connected between the top wall of the base 110 and the outer side wall of the cartridge 130.

[0077] In some embodiments, the rotation axis direction of the cartridge 130 can be parallel to the horizontal direction X, so that the cartridge 130 can rotate in the vertical plane, which helps to reduce the space required for the rotation of the cartridge 130, reduces the space required for the sample mixing device 100, and can also reduce the interference between the cartridge 130 and the base 110.

[0078] As an example, the third connecting shaft 190 can be connected between the outer side wall of the cartridge 130 and the outer side wall of the base 110, and the axial direction of the third connecting shaft 190 can be parallel to the horizontal direction X.

[0079] Please refer to Figures 1 to 2, in some embodiments, the sample mixing device 100 may further include a sealing cover 210. The sealing cover 210 is detachably connected to the barrel 130 and is used to open or seal the material inlet 1351. When the sealing cover 210 is installed on the barrel 130, the sealing cover 210 can seal the material inlet 1351, which helps to avoid material leakage; when the sealing cover 210 is detached from the barrel 130, feeding and discharging can be carried out from the material inlet 1351 at this time. Among them, the sealing cover 210 can be the sealing structure in the above embodiments.

[0080] In some embodiments, a threaded connection can be adopted between the sealing cover 210 and the barrel 130 to detachably connect the sealing tank to the barrel 130.

[0081] As an example, an external thread can be provided on the outer side wall of the barrel 130 at one end of the material inlet 1351, and the sealing cover 210 can be provided with an internal thread adapted to the external thread, so that the sealing cover 210 can be detachably connected to the barrel 130 by means of a threaded connection.

[0082] As another example, an internal thread can be provided on the inner side wall of the barrel 130 at one end of the material inlet 1351, and the sealing cover 210 is provided with an external thread adapted to the internal thread, so that the sealing cover 210 can be detachably connected to the barrel 130 by means of a threaded connection.

[0083] It should be noted that other detachable connection methods can also be adopted between the sealing cover 210 and the barrel 130. For example, the sealing tank can also be clamped to the material inlet 1351.

[0084] In some embodiments, the sample mixing device 100 may further include a sealing ring. The sealing ring can abut between the barrel 130 and the sealing cover 210 to enhance the sealing effect between the sealing cover 210 and the barrel 130, which helps to further improve the problem of material leakage.

[0085] In some embodiments, the barrel 130 can be a transparent barrel, so as to facilitate real-time monitoring of the mixing condition of the materials in the barrel 130 and facilitate real-time adjustment. For example, the barrel 130 can adopt a transparent plastic barrel 130 or a barrel 130 made of other transparent materials.

[0086] As an example, when it is observed that the materials in the barrel 130 are caking or piling up, the user can increase the rotation speed of the stirring member 150 to improve the caking or piling up of the materials; the user can also abandon the current mixing experiment, directly discharge the materials, and re-conduct the mixing experiment after changing the material ratio.

[0087] In some embodiments, the sample mixing device 100 may further include a driving member 230, and the driving member 230 may be connected to the barrel 130. The driving end of the driving member 230 may be connected to the stirring member 150 for driving the stirring member 150 to rotate to stir the materials in the barrel 130, so that manual stirring of the materials is not required, and the stirring efficiency and the uniformity of material mixing are improved.

[0088] Along the rotation axis of the stirring member 150, the material inlet 1351 and the driving member 230 are located at both ends of the barrel 130, which helps to more easily install the driving member 230 and the stirring member 150.

[0089] As an example, the barrel 130 may further be provided with an installation opening 1333, and the installation opening 1333 and the material inlet 1351 may be respectively provided at both ends of the barrel 130. One side of the driving member 230 having the driving end may be inserted into the installation opening 1333 so that the stirring member 150 can be connected to the driving end of the driving member 230.

[0090] The driving member 230 and the barrel 130 may be connected by means of screw connection, bonding or other connection methods.

[0091] Among them, the driving member 230 may adopt a driving motor or other rotary driving structures.

[0092] In some embodiments, the sample mixing device 100 may further include a controller 250, and the controller 250 may be in signal connection with the driving member 230. For example, the controller 250 and the driving member 230 may be connected by an electric wire. The controller 250 may control the on / off and rotation speed of the driving member 230.

[0093] In some embodiments, the connecting member 170 is in a first state. The connecting member 170 may be connected between the driving member 230 and the base 110. Thus, the connecting member 170 can fix the barrel 130 to the base 110 by fixing the driving member 230, and the connection of the connecting member 170 to the driving member 230 can also improve the vibration condition during the operation of the driving member 230, which helps to further reduce the noise during the operation of the sample mixing device 100.

[0094] As an example, the second connecting shaft 173 may be connected to the housing of the driving member 230.

[0095] In some embodiments, the stirring member 150 may include a rotating shaft 151 and a first stirring blade 153 for stirring materials.

[0096] Among them, the rotating shaft 151 can be located inside the barrel 130 and connected to the driving end of the driving member 230; the first stirring blade 153 can be connected to the rotating shaft 151, so that the driving member 230 can drive the rotating shaft 151 to rotate around the axis through the driving end. When the rotating shaft 151 rotates, it drives the first stirring blade 153 to rotate synchronously, and the rotation of the first stirring blade 153 can stir the materials in the barrel 130.

[0097] In some embodiments, the first stirring blade 153 can include a connecting portion and a blade connected to each other. The connecting portion can be sleeved on the rotating shaft 151 and fixed to the rotating shaft 151. The blade can be connected to the connecting portion and extend along the radial direction of the rotating shaft 151 to stir the materials when rotating.

[0098] Among them, the number of blades can be one or more, and more can refer to two or more.

[0099] In some embodiments, the number of the first stirring blades 153 can be one or more, and more can refer to two or more. When the number of the first stirring blades 153 is more than one, the multiple first stirring blades 153 can be distributed along the axial direction of the rotating shaft 151 to stir the materials in a larger area.

[0100] In some embodiments, the first stirring blade 153 can be provided with a number of through holes, so that the first stirring blade 153 is a hollow structure, which helps to better stir the materials and helps to stir the materials more evenly.

[0101] Among them, a number of through holes can specifically refer to two or more through holes.

[0102] The through holes can be circular holes, rectangular holes, polygonal holes, ellipses, semi-circular holes or special-shaped holes, and can be specifically designed according to actual needs.

[0103] The size of the through holes can also be designed according to requirements.

[0104] In some embodiments, a first space 1331 and a second space 1353 that are connected and communicated can be provided inside the barrel 130. The material inlet 1351 is communicated with the second space 1353, and the material inlet 1351, the second space 1353 and the first space 1331 are sequentially distributed along the rotation axis direction of the rotating shaft 151.

[0105] As an example, the barrel 130 may include a peripheral wall that surrounds and forms a receiving space 131. The stirring member 150 and the rotating shaft 151 are both disposed within the receiving space 131. Installation openings 1333 and a material opening 1351 are respectively formed at both axial ends of the peripheral wall along the axial direction of the rotating shaft 151. Along the axial direction of the rotating shaft 151, the peripheral wall may include a connected first section 133 and a second section 135. The first section 133 surrounds and forms a first space 1331, and forms an installation opening 1333 at one end facing away from the second section 135. The second section 135 surrounds and forms a second space 1353, and forms a material opening 1351 at one end facing away from the first section 133. That is, the receiving space 131 includes the first space 1331 and the second space 1353.

[0106] Wherein, the stirring member 150 may further include a second stirring blade 155 for stirring the material. The second stirring blade 155 is connected to the rotating shaft 151, and the second stirring blade 155 can rotate synchronously with the rotating shaft 151 to stir the material.

[0107] The first stirring blade 153 is at least partially located within the first space 1331, and the second stirring blade 155 is at least partially located within the second space 1353. Thus, the first stirring blade 153 and the second stirring blade 155 can cooperate to stir the materials in the two spaces (the first space 1331 and the second space 1353), which helps to avoid the situation of material accumulation in the first space 1331 or the second space 1353, and also helps to make the material mixing more uniform.

[0108] The structure of the second stirring blade 155 may be substantially the same as that of the first stirring blade 153, and the specific shape of the second stirring blade 155 can be designed according to requirements.

[0109] In some embodiments, the second space 1353 is a conical space, and the diameter gradually increases from the material opening 1351 towards the direction of the first space 1331. Thus, the second space 1353 can be generally in the shape of a funnel, which helps to more quickly discharge the material in the barrel 130 from the material opening 1351 during unloading.

[0110] Wherein, the conical space may refer to a conical hole, a pyramidal space or other shaped conical spaces.

[0111] As an example, the inner wall of the second section 135 is generally conical, and the diameter gradually increases from the material opening 1351 towards the direction of the first space 1331.

[0112] In the sampling mixing device 100 provided by the embodiment of the present application, the barrel 130 is rotatably connected to the base 110, and the stirring member 150 is disposed inside the barrel 130; the barrel 130 is provided with a material port 1351 for feeding and discharging materials, so that the same material port 1351 can be shared during loading and unloading, simplifying the structure of the barrel 130. The connecting member 170 has a first state and a second state. When the connecting member 170 is in the first state, the connecting member 170 is connected between the barrel 130 and the base 110 to fix the barrel 130 to the base 110, so that the barrel 130 is in a fixed state and the stirring member 150 can stably stir the materials. When the connecting member 170 is in the second state, the barrel 130 can rotate relative to the base 110, so that the position of the material port 1351 can be adjusted by freely and flexibly manually operating the barrel 130 without a complex driving structure to drive the rotation of the barrel 130. For scenarios with a small sampling mixing base, the operation is more convenient, improving the flexibility of the sampling mixing device 100.

However, the present utility model is not limited to the above embodiments. Within the knowledge scope of those of ordinary skill in the art to which the present utility model pertains, various changes can be made without departing from the gist of the present utility model. In addition, the embodiments of the present utility model and the features in the embodiments can be combined with each other without conflict.
