[0025] In order to make the purpose, technical scheme and advantages of the utility model clearer, the technical scheme of the utility model will be described in detail below. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor belong to the scope protected by the utility model.

[0026] The terms "first", "second", etc. in the specification and claims of the present application are used to distinguish similar objects, and are not used to describe a specific order or sequence. It should be understood that the data used in this way can be interchanged under appropriate circumstances, so that the embodiments of the present application can be implemented in an order other than those illustrated or described herein, and the objects distinguished by "first", "second", etc. are generally of a kind and do not limit the number of objects, for example, the first object can be one or more. In addition, "and / or" in the specification and claims indicates at least one of the connected objects, and the character " / ", generally indicates that the front and rear associated objects are in an "or" relationship.

[0027] In the embodiments of the present application, "proximal end" and "distal end" refer to the relative position of each component to the user in the use environment, wherein the end closer to the user is designated as "proximal end" and the end farther from the user is designated as "distal end".

[0028] During storage, the quality of grain is affected by various factors, such as temperature, humidity, storage time, etc. The quality of grain in the granary, especially the surface layer, often differs from that of the internal grain. Based on this, by inserting a sampling tube into the granary at different depths and positions for sampling, a more representative sample can be obtained, thereby more accurately reflecting the quality condition of the whole warehouse grain.

[0029] The grain in the granary is accumulated too deep, so that a large number of sampling tubes are needed to extract samples at different depths during grain quality inspection. However, these sampling tubes are often heavy and numerous, and are not suitable for fixing and placing. If the sampling tubes to be used are not properly placed or fixed, they are easy to fall and may cause risk of injury to people.

[0030] The present application provides a sampling tube storage tray 100, please refer to Figure 1 The sampling tube storage tray 100 can include a base 110, a first rotating disc 120, a second rotating disc 130, and a plurality of clamping pieces 140, the first rotating disc 120 is rotatably connected to the base 110, the second rotating disc 130 is connected to the first rotating disc 120, and the clamping pieces 140 are arranged on the first rotating disc 120 and / or the second rotating disc 130.

[0031] In the present embodiment, please continue to refer to Figure 1The base 110 can be constructed from multiple trusses to reduce its weight and facilitate the handling and installation of the storage tray 100. Furthermore, the base 110 can be equipped with a drive component 111, which may include, but is not limited to, a drive motor, drive belt, cylinder, etc. This embodiment does not limit the type of drive component 111. However, for ease of subsequent description, a drive motor will be used as an example.

[0032] In other cases, the base 110 can also be an integrated unit, which can improve the structural strength and load-bearing capacity of the base 110, as well as the storage capacity and safety of the storage tray 100.

[0033] Please see Figure 2 The first turntable 120 has multiple first slots 121, which are distributed circumferentially along the first turntable 120. The first slots 121 can be used to fix the sampling tubes 200. More specifically, the multiple first slots 121 can be arranged radially outwards along the first turntable 120. An installer or robotic arm can drive the sampling tubes 200 radially inwards along the first turntable 120 until the sampling tubes 200 are completely installed within the first slots 121, thus completing the storage operation of the sampling tubes 200, allowing multiple sampling tubes 200 to be stored in the storage tray 100. An installer or robotic arm can also drive the sampling tubes 200 radially outwards along the first turntable 120 until the sampling tubes 200 are completely pushed out of the first slots 121, thus completing the unloading operation of the sampling tubes 200.

[0034] Meanwhile, please see Figure 2 The first turntable 120 can be connected to the drive component 111 for transmission. There are multiple first bayonets 121. When a sampling tube 200 needs to be taken out or placed into a designated first bayonet 121, in this embodiment, the drive component 111 can drive the first turntable 120 to rotate to a predetermined position, and multiple sampling tubes 200 will also rotate to the predetermined position to facilitate subsequent taking out or placing of the sampling tubes 200, thereby achieving automatic feeding and retrieval of the sampling tubes 200. This setting improves the automation level of the storage tray 100, further reduces manual operation, and improves the sampling efficiency of the sampling tubes 200.

[0035] Furthermore, the drive unit 111 can drive the first turntable 120 to rotate clockwise or counterclockwise. Preferably, the transmission shaft of the drive unit 111 is located on the axis of the first turntable 120, so that the first turntable 120 is driven to rotate along its own axis, avoiding the center of gravity of the first turntable 120 from shifting, thereby ensuring the stable operation of the storage tray 100 and improving the safety of the storage tray 100 in use.

[0036] To improve the securing effect and safety of the storage tray 100, please refer to the following: Figure 2The second rotating disc 130 of the embodiment is provided with a plurality of second clamping holes 131 distributed along the circumference of the second rotating disc 130, and the first clamping holes 121 correspond to the second clamping holes 131 one by one. The first clamping holes 121 and the second clamping holes 131 arranged correspondingly can clamp the same sample tube 200 at the same time, further fix the sample tube 200 in the storage tray 100, avoid the sample tube 200 from swinging, vibrating and other situations, and improve the fixing effect of the storage tray 100.

[0037] Preferably, the plurality of second clamping holes 131 are arranged along the radial direction of the second rotating disc 130 outward, in other words, the first clamping holes 121 and the second clamping holes 131 are arranged in the same direction. This arrangement can facilitate the taking out or placing of the sample tube 200 in the storage tray 100, improve the work efficiency of sampling the sample tube 200, and also improve the use safety of the storage tray 100, avoiding the situation that the center of gravity of the sample tube 200 is unstable.

[0038] Please continue to refer to Figure 2 The second rotating disc 130 is arranged correspondingly and connected with the first rotating disc 120. In other words, the second rotating disc 130 can rotate together with the first rotating disc 120, that is, the second rotating disc 130 can also be arranged to rotate relative to the base 110. This arrangement can make the sample tube 200 more stable in rotating to the designated position, facilitating the taking out or placing of the sample tube 200 in the storage tray 100 by the installation personnel or the mechanical arm. In addition, the axis of the first rotating disc 120 is collinear with the axis of the second rotating disc 130, which can make the first rotating disc 120 and the second rotating disc 130 rotate more stably.

[0039] More specifically, please continue to refer to Figure 2 The storage tray 100 can also include a plurality of second connecting rods 150. The plurality of second connecting rods 150 are distributed along the circumference of the second rotating disc 130 and arranged at intervals, and each second connecting rod 150 is connected between the first rotating disc 120 and the second rotating disc 130. The plurality of second connecting rods 150 can improve the connection stability between the first rotating disc 120 and the second rotating disc 130, and synchronize the rotating speeds of the first rotating disc 120 and the second rotating disc 130, to ensure that the storage tray 100 can operate normally.

[0040] When the storage tray 100 is subjected to vibration or impact, the sample tube 200 may fall off or the like. Please refer to Figure 3The clamping piece 140 of the embodiment is arranged at the first clamping opening 121 and / or the second clamping opening 131, and is used to clamp the sampling tube 200 placed in the first clamping opening 121 and / or the second clamping opening 131. The clamping piece 140 can be matched with the outer contour of the sampling tube 200, so that the clamping piece 140 can clamp the sampling tube 200. This arrangement can fix the sampling tube 200 by the clamping piece 140, so as to avoid the sampling tube 200 from being separated from the storage tray 100, and eliminate the risk of falling and hurting people caused by the sampling tube 200. Further, the protection capability and use safety of the storage tray 100 are improved.

[0041] In a more specific embodiment, the clamping piece 140 can be arranged at the second clamping opening 131, and is used to clamp the sampling tube 200 placed in the second clamping opening 131. The first rotating disc 120 is driven to rotate the plurality of sampling tubes 200. The driving force can cause the end of the plurality of sampling tubes 200 away from the first rotating disc 120 to swing, vibrate and the like, but the clamping piece 140 arranged at the second clamping opening 131 can stably clamp the sampling tube 200. This arrangement can avoid the sampling tube 200 from swinging, vibrating and the like, and improve the use safety of the storage tray 100.

[0042] In another embodiment, the clamping piece 140 can be arranged at the first clamping opening 121, and is used to clamp the sampling tube 200 placed in the first clamping opening 121. In other words, a plurality of clamping pieces 140 are arranged at a plurality of first clamping openings 121. This arrangement can stably connect the sampling tube 200 and the first rotating disc 120, and the driving force of the first rotating disc 120 can be more uniformly transmitted to the sampling tube 200 under the driving of the driving piece 111, so as to improve the rotation stability of the sampling tube 200.

[0043] In another embodiment, a plurality of clamping pieces 140 are arranged at the first clamping opening 121 and the second clamping opening 131. In other words, a part of the plurality of clamping pieces 140 are arranged at the plurality of first clamping openings 121, and the remaining part are arranged at the plurality of second clamping openings 131. The sampling tube 200 can be stably connected with the first rotating disc 120 and the second rotating disc 130 at the same time. This arrangement can further improve the use safety of the storage tray 100.

[0044] It can be understood that, for the convenience of subsequent writing, the embodiment is described by taking the example that the clamping piece 140 is arranged at the second clamping opening 131.

[0045] Please continue to refer to Figure 3 and Figure 4The plurality of clamping members 140 can each include an elastic member 141, a first clamping portion 142, and a second clamping portion 143. The first clamping portion 142 and the second clamping portion 143 can be correspondingly arranged, and the first clamping portion 142 and the second clamping portion 143 can be rotatably arranged relative to the second turntable 130. The elastic member 141 can include, but is not limited to, a spring or the like.

[0046] The elastic member 141 is connected between the first clamping portion 142 and the second clamping portion 143, and the elastic member 141 provides a driving force for the first clamping portion 142 and the second clamping portion 143 to move towards each other, i.e., the elastic member 141 is used to drive the first clamping portion 142 and the second clamping portion 143 to move towards each other to clamp the sample tube 200. The elastic member 141 can continuously exert a pulling force between the first clamping portion 142 and the second clamping portion 143, so that the first clamping portion 142 and the second clamping portion 143 can continuously clamp the sample tube 200, thereby improving the safety of the storage tray 100.

[0047] In addition, please continue to refer to Figure 3 The first clamping portion 142 can be provided with a first recess 144, and the second clamping portion 143 can be provided with a second recess 145. The first recess 144 and the second recess 145 are correspondingly arranged and correspondingly arranged with the outer contour of the sample tube 200. When the clamping member 140 clamps the sample tube 200, the first recess 144 and the second recess 145 abut against the outer wall of the sample tube 200. The contact surface between the sample tube 200 and the first recess 144 and the second recess 145 has a friction force, which avoids the movement of the sample tube 200 in the clamping member 140, and further improves the safety of the sample tube 200.

[0048] In addition, the first recess 144 and the second recess 145 can also increase the contact area between the clamping member 140 and the sample tube 200, so that the sample tube 200 is subjected to a more uniform clamping force, thereby improving the stability of the sample tube 200 in the storage tray 100.

[0049] In the present embodiment, please continue to refer to Figure 3 One end of the elastic member 141 is connected to the first clamping portion 142 away from the first or second clamping portion 143, and the other end is connected to the second clamping portion 143 away from the first or second clamping portion 131. For example, the clamping member 140 is arranged at the first clamping portion 121, and one end of the elastic member 141 of the clamping member 140 is connected to the first clamping portion 142 away from the first clamping portion 121, and the other end is connected to the second clamping portion 143 away from the first clamping portion 121. This arrangement can avoid the elastic member 141 interfering with the insertion or removal operation of the sample tube 200 while driving the first clamping portion 142 and the second clamping portion 143 to clamp the sample tube 200, thereby further improving the use effect of the storage tray 100.

[0050] Please continue to refer to Figure 3 , the end of the first clamping part 142 close to the first or second bayonet 121 131 is configured as an arc structure, and the end of the second clamping part 143 close to the first or second bayonet 121 131 is configured as an arc structure. The arc structure has a certain guiding effect, which effectively guides the sampling tube 200 to be placed into the first or second bayonet 121 131, improves the efficiency of taking out or placing the sampling tube 200, and shortens the operation time of sampling the sampling tube 200.

[0051] And, please continue to refer to Figure 3 The sampling tube 200 is also provided with a plurality of limiting pieces 146, and the plurality of limiting pieces 146 correspond one-to-one with the plurality of clamping pieces 140. Each limiting piece 146 is arranged between the first clamping part 142 and the second clamping part 143 of the same clamping piece 140. The limiting piece 146 is used to limit the relative movement of the first clamping part 142 and the second clamping part 143 to a certain extent, so as to avoid the first clamping part 142 and the second clamping part 143 from being clamped too tightly, which affects the subsequent operation of placing the sampling tube 200 into the storage tray 100. This setting can further improve the efficiency of taking out or placing the sampling tube 200, and shorten the operation time of sampling the sampling tube 200.

[0052] Because a large number of sampling tubes 200 are needed to extract samples from deep places, the sampling tubes 200 are heavy and numerous, and the sampling tubes 200 are easy to slide out of the storage tray 100 under the influence of gravity. In this embodiment, please refer to Figure 1 The storage tray 100 can also include a bearing plate 160, which can be arranged corresponding to the first rotating disc 120, and the bearing plate 160 is connected to the surface of the first rotating disc 120 away from the second rotating disc 130. The bearing plate 160 is used to bear the sampling tube 200, so as to avoid the sampling tube 200 from separating from the storage tray 100 under the influence of gravity, and further improve the safety of the sampling tube 200.

[0053] Please refer to Figure 2 The bearing plate 160 can be a ring structure. Specifically, the bearing plate 160 is provided with an avoiding hole 161 which avoids the driving piece 111. The driving piece 111 or its transmission shaft can extend into the avoiding hole 161 and be in transmission connection with the first rotating disc 120. This setting can not only avoid the interference of the bearing plate 160 with the transmission of the driving piece 111, but also optimize the structure of the storage tray 100 and reduce its volume, so that the storage tray 100 is easy to install and transport.

[0054] In an embodiment, please continue to refer to Figure 2In addition, the storage tray 100 can further include a plurality of first connecting rods 170. The plurality of first connecting rods 170 are distributed along the circumference of the first rotating disc 120 and are arranged at intervals, and each first connecting rod 170 is connected between the bearing disc 160 and the first rotating disc 120. The plurality of first connecting rods 170 can not only improve the connection stability between the bearing disc 160 and the first rotating disc 120, but also synchronize the rotation speeds of the bearing disc 160 and the first rotating disc 120, so that the bearing disc 160, the first rotating disc 120 and the second rotating disc 130 can stably rotate, and the normal use of the storage tray 100 can be ensured.

[0055] In the embodiment, please refer to Figure 1 The storage tray 100 can further be provided with a sensor 180. The sensor 180 is used to detect the relative position of the bearing disc 160, so as to determine the relative position of the sample tube 200. For example, the sensor 180 is installed on the base 110. The sensor 180 can detect the relative position between the bearing disc 160 and the base 110, so as to avoid the situation that the storage tray 100 cannot be rotated to the correct position, and the sample tube 200 cannot be taken out or placed in. In addition, the sensor 180 can be electrically connected with the driving member 111. The sensor 180 can transmit signals with the driving member 111, so as to control the driving member 111 to drive the sample tube 200 to rotate to the specified position.

[0056] In addition, in some other cases, the number of sensors 180 can be multiple. The multiple sensors 180 can be arranged on the first rotating disc 120, the second rotating disc 130 and the bearing disc 160, so as to more accurately control the rotation of the storage tray 100 and improve the work efficiency of the sample tube 200 sampling. Alternatively, the multiple sensors 180 can be arranged on the multiple first clamping holes 121 and the multiple second clamping holes 131, so as to determine the placement of the sample tube 200 and check the safety risks of the storage tray 100.

[0057] Please refer to Figure 5 which is another exemplary embodiment of the present application, and shows a detection system 1. The detection system 1 is applied to the sampling of the sample tube 200. The detection system 1 can include a storage tray 100. The storage tray 100 can store one or more sample tubes 200 and facilitate subsequent placement and use.

[0058] The storage tray 100 and the detection system 1 provided by the embodiment are characterized in that the first rotating disc 120 is provided with first sockets 121, the second rotating disc 130 is provided with second sockets 131, and a plurality of sample tubes 200 can be placed in the plurality of first sockets 121 and the plurality of second sockets 131, so that the plurality of sample tubes 200 can be stored in the storage tray 100. The clamping piece 140 clamps the sample tube 200 placed in the first socket 121 or the second socket 131, and the sample tube 200 can be fixed by the clamping piece 140. The first rotating disc 120 is driven by the driving piece 111 to drive the whole storage tray 100 to rotate. The storage tray 100 can be automatically rotated to a predetermined angle, so as to facilitate the automatic device to take or place the sample tube 200, and improve the automation degree of the storage tray 100 and the adaptation degree of the storage tray 100 to the automatic device. At the same time, the setting can also reduce the manual error, so as to ensure that the sample tube 200 can be accurately placed and taken.
