Description

Technical Field

[0001] The present invention relates to the technical field of grain detection, and in particular to a feeding device and a detection system for a sampling tube. Background Art

[0002] During storage, grain quality is affected by a variety of factors, such as temperature, humidity, and storage time. The quality of grain within a silo, especially the surface layer, often differs from that of the grain further inside. Therefore, by inserting a sampling tube at different depths and locations within the silo, more representative samples can be obtained, providing a more accurate reflection of the quality of the entire silo.

[0003] The grain in the granary is piled so deep that a large number of sampling tubes are needed to extract samples at different depths during grain quality inspections. However, these sampling tubes are often heavy and numerous, and a feeding device is often used to move the sampling tubes from the storage tray. However, the size of the feeding device is limited by the size of the storage tray and should not be set too large, which will affect the feeding device's carrying range.

[0028] To make the objectives, technical solutions, and advantages of the present invention more apparent, the technical solutions of the present invention will be described in detail below. Obviously, the embodiments described are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other implementations obtained by those of ordinary skill in the art without inventive effort are within the scope of protection of the present invention.

[0029] The terms "first," "second," and the like in the specification and claims of this application are used to distinguish similar objects, and are not used to describe a specific order or precedence. It should be understood that the terms used in this manner are interchangeable where appropriate, so that the embodiments of this application can be implemented in an order other than that illustrated or described herein, and that the objects distinguished by "first," "second," and the like are generally of the same type, and do not limit the number of objects; for example, the first object can be one or more. In addition, the term "and / or" in the specification and claims refers to at least one of the connected objects, and the character " / " generally indicates that the objects connected are in an "or" relationship.

[0030] In each embodiment of the present application, "proximal end" and "distal end" refer to the position of each component relative to the user in the use environment, wherein the end closer to the user is designated as the "proximal end" and the end farther from the user is designated as the "distal end".

[0031] During storage, grain quality is affected by a variety of factors, such as temperature, humidity, and storage time. The quality of grain within a silo, especially the surface layer, often differs from that of the grain further inside. Therefore, by inserting a sampling tube at different depths and locations within the silo, more representative samples can be obtained, providing a more accurate reflection of the quality of the entire silo.

[0032] Grain is piled so deeply in granaries that grain quality inspections require numerous sampling tubes to extract samples at varying depths. However, these tubes are often heavy and numerous, necessitating a feeding mechanism to move them from the storage tray. However, the size of the feeding mechanism is limited by the size of the storage tray and should not be too large, as this would restrict the feeding mechanism's handling range. Manually moving and placing the tubes one by one at remote locations consumes considerable time and effort, significantly impacting work efficiency.

[0033] This application provides a feeding device for a sampling tube, please refer to Figure 1 The feeding device 100 is referred to as the feeding device 100 below. The feeding device 100 may include a storage tray 110, a telescopic assembly 120, a clamping assembly 130 and a driving assembly 140. The storage tray 110 and the clamping assembly 130 are correspondingly arranged, and the telescopic assembly 120 is connected to the driving assembly 140 and the clamping assembly 130.

[0034] See also Figure 2The storage tray 110 is used to accommodate the sampling tubes 200, and the plurality of sampling tubes 200 are distributed along the circumference of the storage tray 110. The plurality of sampling tubes 200 can be fixed in the storage tray 110, and for the convenience of subsequent use, the sampling tubes 200 can be distributed along the circumference of the storage tray 110. The storage tray 110 is rotatably arranged relative to the telescopic assembly 120 and the clamping assembly 130. When a plurality of sampling tubes 200 are needed, the storage tray 110 can drive the sampling tubes 200 to rotate to predetermined positions in sequence for sequential use. The setting of the storage tray 110 can not only improve the placement and use efficiency of the sampling tubes 200, but also improve the volume ratio of the sampling tubes 200 and reduce the volume of the feeding device 100.

[0035] In this example, see Figure 3 The telescopic assembly 120 is disposed above the storage tray 110. This arrangement facilitates the telescopic assembly 120 in removing or placing the sampling tube 200 from the storage tray 110. Furthermore, the telescopic assembly 120 acts on the higher portion of the sampling tube 200, reducing the risk of the sampling tube 200 falling from a height. The telescopic assembly 120 is located within the accommodating space 118 formed by the multiple sampling tubes 200. The telescopic assembly 120 can move radially along the storage tray 110, cooperating with the rotation of the storage tray 110 to enable the telescopic assembly 120 to act on the sampling tube 200 at each position, thereby improving the effectiveness of the telescopic assembly 120.

[0036] In addition, the telescopic component 120 does not occupy any space other than the accommodating space 118, and it does not affect the volume of the feeding device 100. Especially when conducting inspections in a granary, the smaller volume enables the feeding device 100 to enter smaller places and perform sampling and inspections at more locations, thereby ensuring the accuracy of sample inspections.

[0037] The scope of action of the telescopic assembly 120 is limited by the size of the telescopic assembly 120, that is, the larger the size of the telescopic assembly 120, the larger its scope of action. However, the size of the accommodating space 118 enclosed by the sampling tube 200 may affect the volume and scope of action of the telescopic assembly 120. The telescopic assembly 120 in this embodiment may include a first arm body 121 and a second arm body 122 connected to each other. The first arm body 121 and the second arm body 122 may be a plate-like structure or a rod-like structure, etc., which is not limited in this embodiment. The second arm body 122 is slidably arranged relative to the first arm body 121. For example, the first arm body 121 and the second arm body 122 can be connected by a slider and a slide groove. More specifically, the first arm body 121 is provided with a first guide rail 1211, the first guide rail 1211 extends along a first direction, and the second arm body 122 is slidably fitted to the first guide rail 1211. The telescopic setting between the first arm 121 and the second arm 122 can increase the range of action of the telescopic component 120 and reduce the idle volume of the telescopic component 120, which is conducive to its application in a smaller accommodating space 118, so as to balance the range and volume of the telescopic component 120 and improve the use effect of the telescopic component 120.

[0038] Please continue reading Figure 3 The clamping assembly 130 is used to clamp or release the sampling tube 200 in the storage tray 110. This arrangement can utilize the clamping assembly 130 to complete the use and storage of the sampling tube 200. The clamping assembly 130 is slidably connected to the second arm body 122. After the clamping assembly 130 can clamp the sampling tube 200, the clamping assembly 130 and the sampling tube 200 are slidably arranged relative to the second arm body 122. For example, the second arm body 122 is provided with a second guide rail 1221, and the second guide rail 1221 extends along the first direction, and the clamping assembly 130 is slidably fitted with the second guide rail 1221. In addition, the relative sliding arrangement between the first arm body 121 and the second arm body 122 allows the feeding device 100 to achieve two-stage telescopic movement, further improving the range of action of the clamping assembly 130, and the clamping assembly 130 can grab the sampling tube 200 to a farther distance. At the same time, the two-stage telescopic setting can further reduce the volume of the feeding device 100, which is beneficial to the transportation and use of the feeding device 100.

[0039] For more details, please refer to Figure 3The clamping assembly 130 includes a first clamping portion 131, a second clamping portion 132, and a second drive motor 133. The first clamping portion 131 and the second clamping portion 132 are arranged opposite each other. The second drive motor 133 is connected between the first clamping portion 131 and the second clamping portion 132, and is used to drive the first clamping portion 131 and the second clamping portion 132 to move toward or away from each other, so that the first clamping portion 131 and the second clamping portion 132 clamp or release the sampling tube 200. This arrangement can utilize the second drive motor 133 to complete the grasping and releasing of the sampling tube 200, which has a higher degree of automation, reduces manual operation, and ensures the efficiency of sampling the sampling tube 200.

[0040] The weight of a single sampling tube 200 is heavy. In order to ensure the clamping effect of the clamping assembly 130 and prevent the sampling tube 200 from falling off the clamping assembly 130, please continue to refer to Figure 3 In this embodiment, a first recess 1311 is provided on the surface of the first clamping portion 131 near the second clamping portion 132, and a second recess 1321 is provided on the surface of the second clamping portion 132 near the first clamping portion 131. The first recess 1311 and the second recess 1321 are provided correspondingly, and the first recess 1311 and the second recess 1321 are adapted to the outer surface of the sampling tube 200. When the clamping assembly 130 clamps the sampling tube 200, the first recess 1311 and the second recess 1321 move toward each other until they abut the outer surface of the sampling tube 200. The provision of the first recess 1311 and the second recess 1321 can increase the contact area between the clamping assembly 130 and the sampling tube 200, significantly improving the clamping effect of the clamping assembly 130 and preventing the sampling tube 200 from falling.

[0041] Preferably, the first clamping portion 131 and / or the second clamping portion 132 are provided with a buffer, and the buffer is provided at the first recess 1311 of the first clamping portion 131 and / or the second recess 1321 of the second clamping portion 132. For example, the buffer can be a structural member made of materials such as nylon and polyethylene, which will undergo a certain elastic deformation when clamping. While the buffer has a buffering effect, it can also increase the friction resistance with the sampling tube 200 and improve the clamping stability of the first clamping portion 131 and the second clamping portion 132. The buffer has a certain buffering capacity, and the buffer can abut against the sampling tube 200. The buffer can slow down the clamping effect of the clamping assembly 130 on the sampling tube 200, avoid the sampling tube 200 from being damaged due to uneven force, and improve the safety of the sampling tube 200.

[0042] In this example, please refer to Figure 1The drive assembly 140 is fixed to the first arm 121. The drive assembly 140 is used to drive the second arm 122 to move relative to the first arm 121 in the first direction or the second direction, and simultaneously drive the clamping assembly 130 to move relative to the second arm 122 in the first direction or the second direction. The drive assembly 140 can adjust the relative position between the first arm 121 and the second arm 122, and simultaneously adjust the relative position between the second arm 122 and the clamping assembly 130. This configuration can realize the automated setting of the clamping assembly 130, reduce manual operations, and improve the working efficiency of the feeding device 100.

[0043] The first direction may be an extending direction of the first arm 121 and the second arm 122 , and the second direction may be a direction opposite to the first direction.

[0044] For more details, please refer to Figure 3 The drive assembly 140 may include a first drive motor 141, a drive rod 142, and a connecting block 143. The drive rod 142 may be a rod-shaped structure, and the drive rod 142 extends along a first direction. The drive rod 142 is connected between the first drive motor 141 and the connecting block 143. The first drive motor 141 may be used to drive the drive rod 142 to move in the first direction or the second direction, and the drive rod 142 drives the connecting block 143 to move in the first direction or the second direction. The drive rod 142 has a certain limiting function, which can provide the connecting block 143 with a clear moving path, thereby improving the use effect of the feeding device 100.

[0045] Please also refer to Figure 4 as well as Figure 5 The end of the connecting block 143 away from the driving rod 142 is connected to the second arm 122. The connecting block 143 can be used to drive the second arm 122 to move in the first direction or the second direction. The second arm 122 can move in the first direction or the second direction along with the connecting block 143. This arrangement can effectively drive the second arm 122 to move in the first direction or the second direction, ensuring the flexibility and accuracy of the connecting block 143 in different working scenarios, while greatly improving the overall performance and operational efficiency of the robotic arm.

[0046] See also Figure 5, the connecting block 143 is provided with a mounting groove 1431, and the end of the driving rod 142 close to the connecting block 143 is provided with a snap-in member 1421. The snap-in member 1421 and the mounting groove 1431 are rotationally matched, and the snap-in member 1421 is snapped into the mounting groove 1431. This arrangement can make the snap-in member 1421 and the connecting block 143 move stably along the first direction or the second direction, thereby realizing a stable connection between the driving rod 142 and the connecting block 143. This snap-in connection method is not only simple and efficient, but also easy to maintain and replace. In addition, the rotational fit between the snap-in member 1421 and the mounting groove 1431, and / or the rotational fit between the snap-in member 1421 and the driving rod 142, can eliminate the problem of poor coaxiality between the driving rod 142 and the mounting groove 1431 caused by design tolerances or errors, thereby improving the driving effect of the driving assembly 140.

[0047] In addition, the drive assembly 140 is fixed to the surface of the first arm 121 away from the second arm 122, and the connecting block 143 is located on the side of the first arm 121 and is movable relative to the first arm 121. The connecting block 143 is cleverly located on the side of the first arm 121 and is movable relative to the first arm 121. This arrangement ensures that the connecting block 143 can maintain stability while also allowing for freedom of movement, thereby better meeting the movement requirements of the telescopic assembly 120 in different working scenarios.

[0048] In this example, please refer to Figure 4 The telescopic assembly 120 may further include a synchronization device 123. The synchronization device 123 may be provided on the second arm 122, and the synchronization device 123 is provided adjacent to the second guide rail 1221. The first arm 121 and the clamping assembly 130 are connected to the synchronization device 123. The synchronization device 123 is used to move the second arm 122 relative to the first arm 121 in the first direction or the second direction, and the synchronization belt 1233 drives the clamping assembly 130 to move relative to the second arm 122 in the first direction or the second direction. When the second arm 122 moves relative to the first arm 121 in a predetermined first direction or an opposite second direction, it can synchronously drive the clamping assembly 130 to move correspondingly in the same first direction or the second direction relative to the second arm 122. Such a design not only greatly improves the operational flexibility and coordination of the telescopic assembly 120, but also ensures the stability and accuracy of the clamping assembly 130 during the telescopic process, thereby meeting the scope of use requirements in various complex application scenarios.

[0049] For more details, please refer to Figure 4The synchronization device 123 may include a first pulley 1231, a second pulley 1232, and a synchronous belt 1233. The first pulley 1231 and the second pulley 1232 are arranged opposite each other, distributed along a first direction, and fixed to the second arm 122. The first pulley 1231 and the second pulley 1232 are connected to the synchronous belt 1233 in a transmission manner, and the synchronous belt 1233 can rotate between the first pulley 1231 and the second pulley 1232. The first arm 121 is provided with a driving block 1212, and the clamping assembly 130 is provided with a driven block 134. The synchronous belt 1233 connects the driven block 134 and the driving block 1212. Exemplarily, the driving block 1212 includes a first rack and a first clamping block that are detachably connected, and a portion of the synchronous belt 1233 can be clamped between the first rack and the first clamping block. Driven block 134 includes a detachably connected second rack and second clamping block. Another portion of timing belt 1233 can be clamped between the second rack and the second clamping block, and the first and second racks mesh with timing belt 1233. This arrangement ensures the synchronization of synchronization device 123 during its extension and retraction, ensuring the multi-stage extension and retraction effect of telescopic assembly 120 on clamping assembly 130. This improves the integration of feeding device 100, reduces its size, and expands its application range.

[0050] Furthermore, the driven block 134 and the driving block 1212 are respectively arranged on either side of the line connecting the first pulley 1231 and the second pulley 1232. It is understood that the second arm 122 can move in a first direction relative to the first arm 121, and the driving block 1212 can move in a second direction relative to the synchronizing device 123. Because the driven block 134 and the driving block 1212 are respectively arranged on either side of the synchronous belt 1233, the driven block 134 and the driving block 1212 move in opposite directions relative to the synchronizing device 123, that is, the driven block 134 can move in the first direction relative to the synchronizing device 123. This arrangement can align the movement directions of the clamping assembly 130 and the second arm 122, forming a two-stage telescopic structure, ensuring that the clamping assembly 130 has a wider range of use, while improving the integration of the feeding device 100 and reducing its volume.

[0051] Because the first pulley 1231 and the second pulley 1232 occupy a certain amount of space, the movable space of the driving block 1212 or the driven block 134 is limited, which in turn limits the range of motion of the clamping assembly 130. In this embodiment, the distance between the first pulley 1231 and the second pulley 1232 is greater than the stroke of the second arm 122 on the first guide rail 1211, so that the clamping assembly 130 can have the same displacement distance as the second arm 122. This arrangement ensures that there is sufficient distance between the first pulley 1231 and the second pulley 1232 to ensure that the driving block 1212 and the driven block 134 have sufficient movable travel. In other words, the stroke of the driving block 1212 and the driven block 134 on the synchronizing device 123 is greater than or equal to the maximum movable distance of the second arm 122 relative to the first arm 121. This avoids limiting the range of motion of the driving assembly 140 and ensures that the clamping assembly 130 can have the same displacement distance as the second arm 122.

[0052] Specifically, the second arm 122 has a first end and a second end that are spaced apart from each other, and the first end is provided with a raised portion. The raised portion is provided in a raised position relative to the end face forming the first end, and the raised portion extends in a direction away from the second end. The first pulley 1231 is provided on the raised portion, and the second pulley 1232 is provided on the second end. The raised portion can increase the distance between the first end and the second end, and further increase the distance between the first pulley 1231 and the second pulley 1232, to ensure that there is sufficient distance between the first pulley 1231 and the second pulley 1232, so as to ensure that the driving block 1212 and the driven block 134 have sufficient movable travel. In addition, the protruding raised portion can adapt to the arc-shaped accommodating space 118, thereby preventing the second arm 122 from being configured too large.

[0053] In this example, please refer to Figure 3 The feeding device 100 may also include a drag chain 150, one end of the drag chain 150 is connected to the first arm 121, and the other end is connected to the clamping assembly 130. When the clamping assembly 130 needs to move or adjust its position to grab or release the sampling tube 200, the drag chain 150 can synchronously extend or contract accordingly, and always maintain a close connection with the clamping assembly 130. The drag chain 150 is used for the wiring harness of the second drive motor 133 to pass through. The drag chain 150 can provide a safe and orderly channel for the wiring harness of the second drive motor 133. In the complex feeding process, the wiring harness is easily interfered with and damaged by the external environment, such as being pulled, squeezed or worn. At this time, the drag chain 150 plays its key role.

[0054] In one embodiment, the drag chain 150 can be designed with multiple partitioned channels to neatly accommodate and secure the wire harnesses, preventing them from becoming entangled or otherwise damaged during movement. Furthermore, the drag chain 150 can be constructed from high-performance, wear-resistant and corrosion-resistant materials, such as nylon or polyurethane, to ensure its performance and longevity over extended use. The drag chain 150 not only provides a safe passage for the wire harnesses but also ensures the overall aesthetics and compactness of the feeding device 100.

[0055] Please refer again Figure 2 In this embodiment, the accumulator tray 110 includes a third drive motor 116, which drives the accumulator tray 110 to rotate relative to the clamping assembly 130. This arrangement enhances the automation of the accumulator tray 110, further reducing manual operations and improving sampling efficiency. During this time, the accumulator tray 110 controls at least one of the multiple latches to rotate into the path of the clamping assembly 130. This arrangement reduces the number of operating steps required for the clamping assembly 130 and further improves the efficiency of the feeding device 100.

[0056] In one embodiment, in order to improve the fixing effect and safety of the storage tray 110, please continue to refer to Figure 2 The material storage tray 110 of this embodiment includes a first rotating disk 111 and a second rotating disk 112 that are interconnected. The first rotating disk 111 and the second rotating disk 112 are arranged opposite each other. The first rotating disk 111 is provided with a plurality of first bayonet holes 113, and the second rotating disk 112 is provided with a plurality of second bayonet holes 114. The first bayonet holes 113 and the second bayonet holes 114 correspond one to one. The corresponding first bayonet holes 113 and the second bayonet holes 114 can simultaneously engage the same sampling tube 200, further securing the sampling tube 200 within the material storage tray 110, preventing the sampling tube 200 from swinging or vibrating significantly, and improving the securing effect of the material storage tray 110.

[0057] It is understandable that the multiple bayonet openings opened on the storage tray 110 of this embodiment are the multiple first bayonet openings 113 of the first turntable 111 and / or the multiple second bayonet openings 114 of the second turntable 112. The opening direction of the multiple bayonet openings is radially outward of the storage tray 110. The first bayonet opening 113 and the second bayonet opening 114 can be used to accommodate and fix the sampling tube 200, and the clamping assembly 130 is arranged opposite to the storage tray 110. The clamping assembly 130 cooperates with the third drive motor 116, and the clamping assembly 130 is driven to move in the radial outward direction of the first turntable 111 and take the sampling tube 200 away from the first bayonet opening 113 and the second bayonet opening 114. That is, the material removal operation of multiple sampling tubes 200 can be completed.

[0058] Preferably, please continue to see Figure 2, the distance between two adjacent second bayonet holes 114 is 1.5 times to 2 times the width of the first clamping part 131 and the second clamping part 132. The spacing should not be set too large or too small. An excessively large spacing will reduce the storage capacity of the storage tray 110, thereby affecting the sampling capacity of the sampling tube 200. An excessively small spacing will hinder the first clamping part 131 and the second clamping part 132 from clamping the sampling tube 200 placed on the second bayonet hole 114, thereby hindering the clamping work of the clamping assembly 130. An appropriate spacing can ensure the storage capacity of the storage tray 110 while ensuring that the first clamping part 131 or the second clamping part 132 can extend into the gap between the two adjacent second bayonet holes 114, so as to ensure that the clamping assembly 130 can accurately clamp the sampling tube 200, thereby improving the flexibility and efficiency of use of the clamping assembly 130.

[0059] It is understandable that the first bayonet 113 and the second bayonet 114 correspond one to one. In other words, the distance between two adjacent first bayonet 113 is 1.5 to 2 times the width of the first clamping portion 131 or the second clamping portion 132 , which will not be elaborated here.

[0060] The clamping assembly 130 cooperates with the third drive motor 116. The clamping assembly 130 can move the sampling tube 200 radially inward along the first turntable 111, and the sampling tube 200 can be installed in the bayonet, thereby completing the storage operation of the sampling tube 200, that is, completing the material removal operation of multiple sampling tubes 200.

[0061] Preferably, the distance between the first rotating disk 111 and the second rotating disk 112 (eg Figure 2 d1 in the figure) is 1 / 2 to 3 / 4 times the length of the sampling tube 200. The distance between the first turntable 111 and the second turntable 112 should not be too large or too small. If the distance is too large, the sampling tube 200 may fall off the first turntable 111 or the second turntable 112. If the distance is too small, the fixing effect of the storage tray 110 on the sampling tube 200 may be affected, and the end of the sampling tube 200 may swing. This setting can ensure that the first turntable 111 and the second turntable 112 have an appropriate distance, ensuring that the two have a good fixing effect on the sampling tube 200 and preventing the sampling tube 200 from falling and injuring staff.

[0062] In another embodiment, a large number of sampling tubes 200 are needed to extract samples from the deep part of the granary. The sampling tubes 200 are heavy and there are many of them. The sampling tubes 200 are easily affected by gravity and slide out of the storage tray 110. In this embodiment, please refer to Figure 2The storage tray 110 may further include a carrier tray 115, which may be disposed corresponding to the first turntable 111 and connected to a surface of the first turntable 111 away from the second turntable 112. The carrier tray 115 is used to carry the sampling tube 200, preventing the sampling tube 200 from escaping from the storage tray 110 under the influence of gravity, thereby further improving the safety of the sampling tube 200.

[0063] In another embodiment, the storage tray 110 may further include a clamping member 117, which is disposed at the first bayonet 113 and / or the second bayonet 114 and is used to clamp the sampling tube 200 placed in the first bayonet 113 and / or the second bayonet 114. The clamping member 117 can be adapted to the outer contour of the sampling tube 200 so that the clamping member 117 can clamp the sampling tube 200. This arrangement allows the sampling tube 200 to be fixed by the clamping member 117, thereby preventing the sampling tube 200 from detaching from the storage tray 110 and eliminating the risk of the sampling tube 200 falling and injuring someone. This further improves the protection capability and safety of the storage tray 110.

[0064] Preferably, the depth of the first bayonet 113 and the second bayonet 114 can be 1-1.5 times the diameter of the sampling tube 200. The depth of the first bayonet 113 and the second bayonet 114 should not be too small or too large. A too small setting may cause the sampling tube 200 to be not completely fixed and still have the risk of falling. An excessively large setting may expand the range of motion of the clamping assembly 130 and reduce the working efficiency of the clamping assembly 130. This setting can make the first bayonet 113 and the second bayonet 114 have an appropriate depth, balancing the fixing effect of the sampling tube 200 and the working efficiency of the clamping assembly 130.

[0065] This is another exemplary embodiment of the present application showing a detection system 1, see Figure 6 , the detection system 1 may include the aforementioned feeding device 100. In this way, the detection system 1 has the beneficial effects of any of the aforementioned solutions, which will not be described in detail here.

[0066] The feeding device 100 and the detection system 1 provided in this embodiment, the storage tray 110 can accommodate the sampling tube 200. When the sampling tube 200 is needed for sampling, the clamping assembly 130 clamps the sampling tube 200 and drives it to the designated position through the telescopic assembly 120 to complete the removal of the sampling tube 200. After the sampling of the sampling tube 200 is completed, the clamping assembly 130 can also clamp the sampling tube 200 at the designated position and drive it to the storage tray 110 through the telescopic assembly 120 to complete the placement of the sampling tube 200. This setting improves the degree of automation in the removal of the sampling tube 200, avoids consuming a lot of time and energy, and improves the work efficiency of grain sampling. When the telescopic assembly 120 is idle, it does not occupy other space outside the accommodating space 118, and it does not affect the volume of the feeding device 100. When telescopic assembly 120 is in operation, the multi-stage telescopic structure of first arm 121 and second arm 122 allows clamping assembly 130 to complete multiple movements in the first or second direction, extending the handling range of clamping assembly 130. Even at remote locations, feeding device 100 can be automated for improved work efficiency. This multi-stage telescopic arrangement, while ensuring a sufficient handling range for clamping assembly 130, increases the integration of feeding device 100, reduces its size, and expands its application range.
