[0002] During the storage process of grain, its quality is affected by various factors, such as temperature, humidity, storage time, etc. The quality of the grain in the grain warehouse, especially the surface layer, often differs from that of the internal grain. Based on this, the grain detection device for the grain storage warehouse in the prior art can insert sampling tubes into different depths and positions in the grain warehouse to obtain more representative samples, thereby more accurately reflecting the quality condition of the grain in the whole warehouse.

[0003] However, since the depths of grain warehouses are different, when a deep grain warehouse is encountered, or when sampling detection of grain at different depths is required, the length of the sampling tube needs to be adaptively extended. In the related art, there is a sampling device formed by butt joint combination of multiple sampling tubes, for example, in the patent document with publication number CN201555727U, multiple sampling tubes are butt jointed together through threaded connection, and in addition, the related art uses clamping and other methods to butt joint the sampling tubes together.

[0004] Regardless of which connection method is used, the sampling tubes need to be fixed, so that subsequent connection of the sampling tubes can be facilitated. However, the fixing effect of the sampling tubes in the prior art is poor, and manual assistance is still required for butt joint, which increases labor costs and has low automation degree. CONTENT OF THE UTILITY MODEL

[0005] The present application discloses a sampling tube butt joint device and a grain detection device for a grain storage warehouse to at least partially improve the above technical problems.

[0006] In order to solve the above problems, the present application adopts the following technical solutions:

[0007] On the one hand, the present application provides a sampling tube butt joint device for butt jointing sampling tubes, the sampling tubes having opposite first end portions and second end portions, wherein the first end portion of one of the sampling tubes is used to butt joint the second end portion of another of the sampling tubes, and the sampling tube butt joint device comprises a base plate, and first and second positioning mechanisms. The base plate has a positioning hole penetrating in a first direction, and the positioning hole is used for the sampling tubes to pass through. The first positioning mechanism is arranged on one side of the base plate, and the second positioning mechanism is arranged on the other side of the base plate. In two longitudinally adjacent sampling tubes, the first positioning mechanism is used to position and clamp the upper sampling tube, and the second positioning mechanism is used to position and clamp the lower sampling tube.

[0008] In one embodiment, the first positioning mechanism comprises a driving assembly and two clamping assemblies, the two clamping assemblies are movably arranged on the base plate and located at opposite sides of the positioning hole, and the driving assembly is connected with the two clamping assemblies to drive the two clamping assemblies to move towards or away from each other to position and clamp the sampling tube or release the sampling tube.

[0009] In one embodiment, the driving assembly is one of a reciprocating screw, a forward-reverse screw or a left-right rotating screw, and the two clamping assemblies are arranged at two ends of the driving assembly.

[0010] In one embodiment, the clamping assembly comprises a rotating wheel, when the clamping assembly positions the sampling tube, the sampling tube abuts between at least two rotating wheels, and the axial direction of the rotating wheel is parallel to the first direction.

[0011] In one embodiment, the first positioning mechanism further comprises a driver connected with the rotating wheel and used to drive the rotating wheel to rotate.

[0012] In one embodiment, the second positioning mechanism comprises a base connected with the base plate and at least one positioning wheel set, the positioning wheel set comprises two positioning wheels arranged on the base, the two positioning wheels are arranged in parallel and define a positioning gap therebetween, the positioning gap is used for the sampling tube to pass through, and when the second positioning mechanism positions the sampling tube, the two positioning wheels abut the outer periphery of the sampling tube.

[0013] In one embodiment, the second positioning mechanism further comprises a fixing claw arranged on the base, the fixing claw is distributed along the first direction with the positioning wheel, and the fixing claw is used to clamp the sampling tube.

[0014] In one embodiment, when the positioning wheel set is two sets, the two sets of positioning wheel sets are distributed along the first direction, and the fixing claw is arranged between the two sets of positioning wheel sets.

[0015] In one embodiment, the base comprises a first structure connected with the base plate and extending along the first direction, and a second structure connected with two sides of the first structure, the positioning wheel is rotatably connected between the two second structures, and the axial direction of the positioning wheel is perpendicular to the first direction.

[0016] In another aspect, the embodiments of the present application also provide a grain detection device for a grain storage bin, which comprises the sampling tube docking device as described above.

[0017] The technical scheme adopted by the present application can achieve the following beneficial effects:

[0018] The sampling tube docking device provided in this application embodiment uses positioning holes on a substrate and a first positioning mechanism and a second positioning mechanism on both sides of the substrate to position the sampling tubes to be docked. Specifically, the first positioning mechanism can be located on the upper surface of the substrate, and the second positioning mechanism can be located on the lower surface of the substrate. This allows the first positioning mechanism to be fixed at the lower end of the upper sampling tube, and the second positioning mechanism to be fixed at the upper end of the lower sampling tube. When both sampling tubes are fixed, docking of the two sampling tubes is facilitated, which in turn facilitates subsequent thread tightening or snap-fitting of the sampling tubes. This solves the problems of poor sampling tube fixing effect in the prior art, which still requires manual docking, increases labor costs, and has a low degree of automation. Applying the above-mentioned sampling tube docking device to a grain storage silo grain testing device can also solve the above problems. Attached Figure Description

[0027] To make the objectives, technical solutions, and advantages of this application clearer, the technical solutions of this application will be described in detail below. Obviously, the described embodiments are merely some embodiments of this application, and not all embodiments. Based on the embodiments in this application, all other implementation methods obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0028] The terms "first," "second," etc., used in the specification and claims of this application are used to distinguish similar objects and not to describe a specific order or sequence. It should be understood that such use of data can be interchanged where appropriate so that embodiments of this application can be implemented in orders other than those illustrated or described herein, and the objects distinguished by "first," "second," etc., are generally of the same class and the number of objects is not limited; for example, a first object can be one or more. Furthermore, in the specification and claims, "and / or" indicates at least one of the connected objects, and the character " / " generally indicates that the preceding and following objects are in an "or" relationship.

[0029] The inventive concept of this application is described here:

[0030] During storage, the quality of grain is affected by various factors, such as temperature, humidity, and storage time. The quality of grain in a grain silo, especially the surface layer, often differs from that of the grain inside. Therefore, existing grain testing devices for grain storage silos can obtain more representative samples by inserting sampling tubes into different depths and locations within the silo, thus more accurately reflecting the overall quality of the grain in the silo.

[0031] However, due to the varying depths of grain silos, when encountering deeper silos or when sampling and testing grain at different depths is required, the length of the sampling tube needs to be adapted. Related technologies include sampling devices formed by connecting multiple sampling tubes together. For example, in patent document CN201555727U, multiple sampling tubes are connected together by threads. Other related technologies use snap-fit ​​methods to connect the sampling tubes together.

[0032] Regardless of the connection method used, the sampling tubes need to be fixed in place to facilitate subsequent connection. However, the current technology for fixing sampling tubes is ineffective. Specifically, although the non-connecting ends of the two sampling tubes that need to be joined can be fixed by instruments in the current technology, the length of the sampling tubes is usually quite long. Therefore, the ends of the two sampling tubes that need to be joined are prone to swinging, which still requires manual assistance for connection, increasing labor costs and resulting in low automation.

[0033] Based on this, the inventor provides a sampling tube docking device. By setting two positioning mechanisms and using these two positioning mechanisms to fix the lower end of the upper sampling tube and the upper end of the lower sampling tube respectively, the ends that need to be docked can be kept relatively fixed, thus preventing swaying and improving the efficiency of sampling tube splicing.

[0034] The following is in conjunction with the appendix Figures 1 to 6 The sampling tube docking device 10 provided in this application will be described in detail through specific embodiments and application scenarios.

[0035] To facilitate understanding of the scheme in this application, the structure of the sampling tube 2 is first introduced. Please refer to [link / reference]. Figure 1 The sampling tube 2 is typically a linear tube with a first end 210 and a second end 220. The first end 210 of one sampling tube 2 can be used to connect to the second end 220 of another sampling tube 2. For example, in one embodiment, the first end 210 of the sampling tube 2 may have an internal thread, and the second end 220 of the sampling tube 2 may have an external thread that matches the aforementioned internal thread. This facilitates connecting multiple sampling tubes 2 together to improve the overall strength of the sampling tube 2.

[0036] Please also refer to Figure 2 and Figure 3 In this embodiment, the sampling tube docking device 10 may include: a base plate 110, a first positioning mechanism 120 and a second positioning mechanism 130, wherein the base plate 110 can serve as a carrier for the first positioning mechanism 120 and the second positioning mechanism 130, and the first positioning mechanism 120 and the second positioning mechanism 130 can be respectively disposed on both sides of the base plate 110 and are respectively used to position the mutually close ends of the two sampling tubes 2.

[0037] It should be noted that the embodiments of this application do not limit the specific form and structure of the substrate 110. Preferably, in this embodiment, the substrate 110 can be set as a plate-like structure with a flat surface, which can facilitate the installation of the first positioning mechanism 120 and the second positioning mechanism 130. The substrate 110 can be provided with positioning holes 111, which can penetrate along the first direction (Z direction in the figure). Preferably, the first direction can be a vertical direction, that is, the first direction can be perpendicular to the surface of the substrate 110.

[0038] Please also refer to Figure 2 , Figure 3 and Figure 4 The first positioning mechanism 120 can be used to position and clamp the upper sampling tube 2, specifically to position the second end 220 of the upper sampling tube 2, preventing the upper sampling tube 2 from swinging during docking. In this embodiment, the first positioning mechanism 120 may include a driving component 121 and a clamping component 122. The driving component 121 can be used to drive the clamping component 122 to move, so as to selectively position and clamp the sampling tube 2 or release the sampling tube 2.

[0039] In this embodiment, multiple clamping components 122 can be provided, such as two, three, or four, etc., without any specific limitation. The clamping components 122 can be evenly arranged around the positioning hole 111. Specifically, for ease of explanation, the following description will take two clamping components 122 as an example.

[0040] Two clamping components 122 are positioned on opposite sides of the positioning hole 111 in the radial direction, which improves the positioning and clamping effect of the clamping components 122 on the sampling tube 2. The driving component 121 can be used to drive the two clamping components 122 to move towards or away from each other. Specifically, when the two clamping components 122 move towards each other, they can be used to position and clamp the sampling tube 2; when the two clamping components 122 move away from each other, they can be used to release the sampling tube 2.

[0041] Please refer to it again. Figure 2 and Figure 4 In a more specific embodiment, the drive assembly 121 can be one of a reciprocating screw, a forward and reverse threaded screw, or a left and right threaded screw, and the two clamping assemblies 122 can be respectively disposed at both ends of the drive assembly 121. Taking the drive assembly 121 as a reciprocating screw as an example, this screw has two threaded grooves with the same pitch but opposite directions of rotation. By rotating the screw, the two clamping assemblies 122 can be driven to reciprocate in opposite directions along the screw axis, thereby realizing the positioning and clamping of the sampling tube 2 or the release of the sampling tube 2 by the two clamping assemblies 122.

[0042] Furthermore, this application does not limit the specific form and structure of the clamping component 122. For example, in some embodiments, the clamping component 122 can be configured as a clamping block, and the sampling tube 2 can be positioned and clamped by abutment and compression. As another example, in this embodiment, the clamping component 122 may include rotating wheels 122a. When the clamping component 122 positions the sampling tube 2, the sampling tube 2 abuts between at least two rotating wheels 122a. Specifically, taking the sampling tube 2 abutting against three rotating wheels 122a as an example, one side of the sampling tube 2 abuts against one rotating wheel 122a, and the other side abuts against two rotating wheels 122a. The triangularly stable structure can firmly position and clamp the sampling tube 2. Preferably, both sides of the sampling tube 2 can abut against two rotating wheels 122a, which facilitates the fixation of the sampling tube 2.

[0043] It should be noted that in this embodiment, the axial direction of the rotating wheel 122a can be parallel to the first direction, that is, the axial direction of the rotating wheel 122a is also parallel to the axial direction of the sampling tube 2, so that the sampling tube 2 and the rotating wheel 122a can rotate relative to each other.

[0044] Furthermore, in this embodiment, the first positioning mechanism 120 may also include a driver 124, which may be connected to the rotating wheel 122a and used for the rotation of the driver 124. This embodiment of the application does not limit the specific structure and form of the driver 124. For details, please refer to the relevant description of the driving component 121, which will not be repeated here.

[0045] In this embodiment, the rotating wheel 122a can be a driving wheel. When the rotating wheel 122a abuts against the outer surface of the sampling tube 2, it can rotate under the drive of the driver 124, thereby driving the sampling tube 2 to rotate. Since the two sampling tubes 2 are connected by threads, the upper sampling tube 2 can rotate when driven by the rotating wheel 122a. It should be noted that the direction of rotation is not limited here. That is, when the upper sampling tube 2 rotates, it can be threadedly connected to the lower sampling tube 2 or separated from it. Therefore, in this embodiment, the first positioning mechanism 120 not only has the function of positioning the sampling tube 2, but also can rotate the upper sampling tube 2, so that the two sampling tubes 2 can be threadedly connected or disassembled, thereby realizing the quick completion of the splicing operation after the sampling tubes 2 are connected or the quick disassembly operation of the two sampling tubes 2.

[0046] It should be noted that, in this embodiment, since the docking of the sampling tube 2 is performed at the end, the rotating wheel 122a is positioned near the end of the sampling tube 2, which can improve the docking effect and accuracy of the sampling tube 2, and at the same time save effort and reduce the driving burden of the driver 124.

[0047] Furthermore, in some embodiments, the first positioning mechanism 120 may also include a guide 123, which may be disposed on the base 131, and the clamping assembly 122 may be movably disposed on the guide 123. This ensures a more precise movement path for the clamping assembly 122 and more precise positioning and clamping of the sampling tube 2 by the clamping assembly 122. It should be noted that the embodiments of this application do not limit the specific structure of the guide 123. For example, in one embodiment, the guide 123 may be a guide rail, and the clamping assembly 122 may be movably disposed on the guide rail. This not only ensures a more accurate movement path for the clamping assembly 122 but also improves the structural stability of the clamping assembly 122 relative to the base 131, preventing the sampling tube 2 from colliding with the clamping assembly 122 during swinging, thus avoiding displacement of the clamping assembly 122.

[0048] This application does not limit the specific form of the second positioning mechanism 130. For example, in one embodiment, the second positioning mechanism 130 can be configured in the same way as the first positioning mechanism 120. For details, please refer to the configuration of the first positioning mechanism 120, which will not be elaborated here.

[0049] Please also refer to Figure 3 and Figure 5 In this embodiment, the second positioning mechanism 130 may include a base 131 and at least one positioning wheel assembly. The base 131 may be connected to the substrate 110. The positioning wheel assembly may include two positioning wheels 132 disposed on the base 131. Both positioning wheels 132 are rotatably connected to the base 131. The two positioning wheels 132 may be arranged in parallel, and a positioning gap 134 may be defined between the two positioning wheels 132. The positioning gap 134 may be used for the sampling tube 2 to pass through. When the second positioning mechanism 130 positions the sampling tube 2, the sampling tube 2 may be inserted into the positioning gap 134, and the two positioning wheels 132 may abut against the outer periphery of the sampling tube 2.

[0050] Preferably, the contact surface between the positioning wheel 132 and the sampling tube 2 can be concave. When the second positioning mechanism 130 positions the sampling tube 2, the outer surface of the sampling tube 2 can be wrapped around the outer surfaces of the two positioning wheels 132. This not only improves the positioning and clamping effect of the sampling tube 2, but also reduces the possibility of damage to the sampling tube 2 caused by the external environment. Specifically, in this embodiment, the axial direction of the positioning wheel 132 can be perpendicular to the first direction, that is, the axial direction of the positioning wheel 132 can also be perpendicular to the axial direction of the sampling tube 2.

[0051] This application embodiment does not limit the specific structure of the substrate 131; it can be configured according to actual conditions. In this embodiment, the substrate 131 may include a first structural portion 132a and a second structural portion 132b, wherein the first structural portion 132a can be connected to the substrate 110 and extends along a first direction, disposed away from the substrate 110. Specifically, in this embodiment, the first structural portion 132a can be configured as a structure similar to a hanging basket. The second structural portion 132b can be configured as a sheet-like structure with a hollowed-out central portion, and the second structural portion 132b can be connected to both sides of the first structural portion 132a. The positioning wheel 132 can be rotatably connected between the two second structural portions 132b.

[0052] Furthermore, in this embodiment, multiple sets of positioning wheels can be provided, and these multiple sets of positioning wheels can be arranged along the first direction, which can further increase the positioning and clamping effect of the second positioning mechanism 130 on the sampling tube 2.

[0053] In one embodiment, the second positioning mechanism 130 may further include a fixing claw 133, which may be disposed on the base 131, specifically on the first structural portion 132a, and connected to the surface of the first structural portion 132a away from the substrate 110. The fixing claw 133 can be used to selectively grip or release the sampling tube 2, thereby further improving the positioning and clamping capability of the second positioning mechanism 130 on the sampling tube 2. In a more specific embodiment, when two sets of positioning wheels are provided, the fixing claw 133 may be disposed between the two sets of positioning wheels.

[0054] In addition, please see Figure 6 This application embodiment also provides a grain storage warehouse grain testing device 1, which includes any of the sampling tube docking devices 10 described above, so that the grain storage warehouse grain testing device 1 can be spliced ​​with sampling tubes 2 more quickly, which is conducive to improving the efficiency of grain testing.

[0055] In summary, the sampling tube docking device 10 provided in this application embodiment provides a positioning hole 111 on a substrate 110, and a first positioning mechanism 120 and a second positioning mechanism 130 on both sides of the substrate 110. The first positioning mechanism 120 and the second positioning mechanism 130 are used to position the sampling tube 2 to be docked. Specifically, the first positioning mechanism 120 can be located on the upper surface of the substrate 110, and the second positioning mechanism 130 can be located on the lower surface of the substrate 110. This allows the first positioning mechanism 120 to be fixed at the lower end of the upper sampling tube 2, and the second positioning mechanism 130 to be fixed at the upper end of the lower sampling tube 2. When both sampling tubes 2 are fixed, it is easier to dock the two sampling tubes 2, which is beneficial for subsequent thread tightening or clamping of the sampling tubes 2. This solves the problems of poor fixing effect of the sampling tubes 2 in the prior art, which still requires manual docking, increases labor costs, and has a low degree of automation. Applying the above-mentioned sampling tube docking device 10 to the grain testing device 1 in the grain storage warehouse can also solve the above problems.
