The second rotating member and the second driven member are connected by transmission through the conveying member. The second rotating member and the second driven member are rotatably arranged around a third direction, and the third direction, the second direction, and the first direction intersect each other. The second driven members are arranged in multiple intervals along the second direction. The conveying member forms a conveying surface within the distribution range of the multiple second driven members along the second direction.

[0020] The features and exemplary embodiments of various aspects of this application will be described in detail below. To make the objectives, technical solutions, and advantages of this application clearer, the application will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described herein are only intended to explain this application and not to limit it. For those skilled in the art, this application can be implemented without some of these specific details. The following description of the embodiments is merely to provide a better understanding of this application by illustrating examples.

[0021] It should be noted that, in this document, relational terms such as "first" and "second" are used merely to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitations, an element defined by the phrase "comprising..." does not exclude the presence of additional identical elements in the process, method, article, or apparatus that includes said element.

[0022] During the operation of the transplanter, it is necessary to ensure the stability of the transfer of seedlings or saplings to ensure reliable and stable transportation. During transportation, it is also necessary to minimize damage to the seedlings or saplings to improve their survival rate after transplanting.

[0023] In view of this, firstly, please refer to Figure 1 , Figure 2 and Figure 3 This application provides a conveying device, including a base 10, a support assembly 20, a lifting assembly 30, and a conveying assembly 40. The support assembly 20 is connected to the base 10 and has a support surface M1 in a first direction X. The lifting assembly 30 is connected to the base 10 and includes a lifting platform 31 spaced apart from the base 10 in the first direction X. The lifting platform 31 is drive-connected to the base 10 and is movably disposed relative to the base 10 along the first direction X. The conveying assembly 40 is connected to the side of the lifting platform 31 facing away from the base 10 along the first direction X. The conveying assembly 40 includes a conveying member 41 that transmits along a second direction Y, which intersects with the first direction X. The conveying assembly 40 includes a first position and a second position along the first direction X. In the first position, the conveying member 41 is located on the side of the first direction X where the support surface M1 faces the base 10; in the second position, the conveying member 41 is located on the side of the first direction X where the support surface M1 faces away from the base 10.

[0024] The conveying device provided in this application embodiment is mainly used in transplanters to transport seedlings or saplings that need to be transferred. While ensuring the stability of the transport, it also reduces damage to the seedlings or saplings, ensuring a high survival rate after transplanting. Specifically, the conveying device includes a base 10, a support component 20, a lifting component 30, and a conveying component 40. The base 10 provides an installation position for the other structures in the conveying device. The support component 20, the lifting component 30, and the conveying component 40 work together to transport the seedlings or saplings.

[0025] In this embodiment of the application, for ease of description, the conveying device for transporting seedlings is used as an example. The support component 20 is connected to the base 10 and has a support surface M1 in the first direction X. During the transport of the seedlings, the support component 20 can stably support the seedlings. The seedlings are located on one side of the support surface M1, and the support surface M1 can contact the seedlings and support them in the first direction X.

[0026] After the support component 20 provides stable support for the sapling, the lifting component 30 and the conveying component 40 can cooperate to convey the sapling on the support component 20 along a specific direction. The lifting component 30 includes a lifting platform 31 spaced apart from the base 10 in the first direction X. The lifting platform 31 is connected to the base 10 by transmission, and the lifting platform 31 is movable relative to the base 10 along the first direction X. That is, the distance between the lifting platform 31 and the base 10 in the first direction X can be adjusted, the distance between the lifting platform 31 and the support surface M1 in the first direction X can be adjusted, and the distance between the lifting platform 31 and the sapling in the first direction X can also be adjusted when the sapling is on the support surface M1.

[0027] The conveying assembly 40 is connected to the side of the lifting platform 31 opposite to the base 10 along the first direction X. As the lifting platform 31 moves up and down along the first direction X, the conveying assembly 40 also moves up and down along the first direction X. The conveying assembly 40 includes a conveying component 41 that transmits along the second direction Y. When the conveying assembly 40 moves up and down along the first direction X with the lifting platform 31, the conveying component 41 can come into contact with the sapling. After contact with the sapling, the conveying component 41 can transport the sapling along the second direction Y.

[0028] Specifically, during the lifting process of the lifting platform 31 along the first direction X, the conveying component 40 includes a first position and a second position in the first direction X. In the first position, the conveying component 41 is located on the side of the support surface M1 facing the base 10. That is, the conveying component 41 does not protrude from the support surface M1 in the first direction X, and the conveying component 41 does not contact the sapling on the support surface M1. The sapling is stably supported by the support component 20. In the second position, the conveying component 41 is located on the side of the support surface M1 facing away from the base 10. That is, the conveying component 41 protrudes from the support surface M1 in the first direction X. The conveying component 41 contacts and supports the sapling. Since the conveying component 41 protrudes from the support surface M1, during the process of the conveying component 41 supporting the sapling, the sapling loses contact with the support surface M1, and the conveying component 41 conveys the sapling along the second direction Y.

[0029] When the support assembly 20 supports the sapling, the conveying assembly 40 is in the first position. The conveying component 41 is positioned on the side of the support surface M1 facing the base 10 in the first direction X. The conveying component 41 is spaced apart from the sapling, and the support assembly 20 provides stable support for the sapling. There is no contact between the conveying component 41 and the sapling, and the conveying component 41 will not cause wear to the sapling. When the conveying assembly 40 conveys the sapling, it is in the second position. The conveying component 41 is positioned on the side of the support surface M1 away from the base 10 in the first direction X. The conveying component 41 provides stable support for the sapling, and the support assembly 20 is spaced apart from the sapling. There is no contact between the support surface M1 and the sapling, and the support assembly 20 will not cause wear to the sapling. In other words, during the process of supporting or conveying the sapling, only one structural component in the conveying device contacts the sapling, and no additional structural components come into contact with the sapling. This ensures stable conveying of the sapling while reducing damage to the sapling, thereby improving the survival rate of the sapling after transplanting.

[0030] In summary, in this embodiment, the conveying device includes a base 10, a support component 20, a lifting component 30, and a conveying component 40. The base 10 provides an installation position for the remaining structures in the conveying device. The support component 20, the lifting component 30, and the conveying component 40 cooperate to convey the seedlings. The support component 20 is connected to the base 10 and has a support surface M1 in the first direction X. During the conveying of the seedlings, the support surface M1 can contact the seedlings and support them in the first direction X. The lifting component 30 includes a lifting platform 31 spaced apart from the base 10 in the first direction X. The lifting platform 31 is movably disposed relative to the base 10 along the first direction X. The conveying component 40 is connected to the side of the lifting platform 31 facing away from the base 10 along the first direction X. During the lifting process of the lifting platform 31 moving up and down in the first direction X, the conveying component 40 also moves up and down with the lifting platform 31 in the first direction X. The conveying assembly 40 includes a conveying component 41 that transports along the second direction Y. When the conveying assembly 40 moves up and down along the first direction X with the lifting platform 31, the conveying component 41 can come into contact with the sapling. After contact with the sapling, the conveying component 41 can transport the sapling along the second direction Y. When the support assembly 20 supports the sapling, the conveying component 41 is spaced apart from the sapling, and the support assembly 20 provides stable support for the sapling. There is no contact between the conveying component 41 and the sapling, and the conveying component 41 will not cause wear to the sapling. When the conveying assembly 40 transports the sapling, the conveying component 41 provides stable support for the sapling. The support assembly 20 is spaced apart from the sapling, and the support surface M1 does not contact the sapling. The support assembly 20 will not cause wear to the sapling. During the process of supporting or transporting the sapling, only one structural component in the conveying device comes into contact with the sapling, and no additional structural components come into contact with the sapling. This ensures stable transport of the sapling while reducing damage to the sapling, thereby improving the survival rate of the sapling after transplanting.

[0031] In some embodiments, please refer to Figure 2 and Figure 3 The conveying device also includes a first transmission assembly 50, which includes a first rotating member 51 connected to the base 10, a first driving member 52 connected to the first rotating member 51, and a first driven member 53 connected to the lifting platform 31. The first rotating member 51 rotates in the second direction Y. The first driving member 52 includes a cam structure, and the first driven member 53 includes a roller structure. The cam structure and the roller structure are in contact.

[0032] During the transport of seedlings, the transport component 40 needs to circulate back and forth between a first position and a second position to progressively transport the seedlings along the second direction Y. The movement of the transport component 40 in the first direction X is driven by the lifting platform 31. A first transmission component 50 is provided between the lifting platform 31 and the base 10. The first transmission component 50 is used to drive the lifting platform 31 to rise and fall in the first direction X, so that the transport component 40 circulates back and forth between the first position and the second position.

[0033] Specifically, to ensure the reliability and stability of the transmission, the first transmission assembly 50 includes a first rotating member 51 connected to the base 10, a first driving member 52 connected to the first rotating member 51, and a first driven member 53 connected to the lifting platform 31. The first rotating member 51 serves as the power source for the first transmission assembly 50, providing rotational power. The first rotating member 51 can drive the first driving member 52 to rotate, and with the cooperation of the first driving member 52 and the first driven member 53, the lifting platform 31 can be raised and lowered in the first direction X. The first driving member 52 includes a cam structure, and the second driven member 52 includes a roller structure. Through the contact transmission between the cam structure and the roller structure, the rotational motion of the first rotating member 51 in the second direction Y is converted into the lifting motion of the lifting platform 31 in the first direction X. The first transmission assembly 50 has fewer transmission structures, thus possessing good transmission reliability and stability, to ensure the reliability and stability of the lifting platform 31's raising and lowering along the first direction X.

[0034] In some embodiments, please refer to Figure 2 and Figure 3 The lifting platform 31 is provided with a clearance groove C on the side facing the first rotating member 51 along the first direction X. The clearance groove C is provided through the lifting platform 31 along the second direction Y. The projections of the first rotating member 51, the first driving member 52, and the first driven member 53 in the second direction Y all overlap with the projections of the clearance groove C in the second direction Y.

[0035] To reduce the overall size of the conveying device in the first direction X, the lifting platform 31 and the first transmission assembly 50 have a certain overlap in size in the first direction X. The lifting platform 31 is provided with a clearance groove C on the side facing the first rotating member 51. Part of the structure of the first rotating member 51, part of the structure of the first driving member 52, and part of the structure of the first driven member 53 are all located inside the clearance groove C, so that the first transmission assembly 50 and the lifting platform 31 are close to each other, thereby reducing the overall size of the conveying device in the first direction X and improving the applicability of the conveying device.

[0036] In some embodiments, please refer to Figure 2 and Figure 3The lifting platform 31 has a through-hole structure K extending along the first direction X, and part of the conveying component 40 is located inside the through-hole structure K. The conveying device also includes a second transmission component 60, which drives the conveying component 41 to move along the second direction Y, and part of the second transmission component 60 is located inside the through-hole structure K.

[0037] To further reduce the overall size of the conveying device in the first direction X, the lifting platform 31 and the second transmission component 60 have a certain overlap in size in the first direction X. The lifting platform 31 is provided with a through hole structure K, and part of the structure of the second transmission component 60 is located inside the through hole structure K, so that the second transmission component 60 and the lifting platform 31 are close to each other, thereby reducing the overall size of the conveying device in the first direction X and improving the applicability of the conveying device.

[0038] In some embodiments, please refer to Figure 2 and Figure 3 The second transmission assembly 60 includes a second rotating member 61 connected to the lifting platform 31 and a second driven member 62 connected to the lifting platform 31. The second rotating member 61 and the second driven member 62 are connected by a conveying member 41. The second rotating member 61 and the second driven member 62 are rotatably arranged around the third direction Z. The third direction Z, the second direction Y, and the first direction X intersect each other. Multiple second driven members 62 are spaced apart along the second direction Y. The conveying member 41 forms a conveying surface M2 within the distribution range of the multiple second driven members 62 along the second direction Y. The conveying member 41 is rotatably arranged around the third direction Z, and different parts of the conveying member 41 alternately form a part of the conveying surface M2 around the third direction Z.

[0039] The second transmission assembly 60 is used to drive the conveyor 41 to transport along the second direction Y. The second transmission assembly 60 includes a second rotating member 61 and a second driven member 62, which are connected by the conveyor 41. The second rotating member 61 is the power source of the second transmission assembly 60. Under the rotation of the second rotating member 61, the conveyor 41 also acts as a transmission member between the second rotating member 61 and the second driven member 62, driving the second driven member 62 to reciprocate, so that the conveyor 41 can reciprocate in the second direction Y to realize the transport of the seedlings.

[0040] To ensure the stability of the seedling transport by the conveyor 41, multiple second driven members 62 are provided. The conveyor 41 is simultaneously connected to multiple second driven members 62, and a conveying surface M2 is formed within the distribution range of the multiple second driven members 62. During the transport of the seedling, the conveying surface M2 provides stable support for the seedling. At the same time, the conveyor 41 rotates in the third direction Z around the circumference, and different parts of the conveyor 41 alternately form a part of the conveying surface M2 to realize the transport of the seedling.

[0041] In some embodiments, please refer to Figure 2 and Figure 3 The second rotating member 61 and the second driven member 62 are spaced apart in the first direction X, and both the second rotating member 61 and the second driven member 62 are located on the side of the conveying surface M2 facing the base 10 in the first direction X. The conveying assembly 40 also includes a first limiting member 42 and a second limiting member 43 spaced apart in the third direction Z. The first limiting member 42 and the second limiting member 43 are both connected to the lifting platform 31. A portion of the structure of the conveying member 41 is located between the first limiting member 42 and the second limiting member 43 in the third direction Z, and at least a portion of the structure of the second driven member 62 is located between the first limiting member 42 and the second limiting member 43 in the third direction Z.

[0042] To ensure the connection stability between the conveying component 41 and the second driven component 62, the conveying assembly 40 also includes a first limiting component 42 and a second limiting component 43 spaced apart along the third direction Z. A limiting space is formed between the first limiting component 42 and the second limiting component 43. Parts of the structure of the conveying component 41 and part of the structure of the second driven component 62 are located inside the limiting space. By setting the first limiting component 42 and the second limiting component 43, the relative positional stability of the conveying component 41 and the second driven component 62 in the third direction Z can be guaranteed to a certain extent, reducing the probability of deviation between the conveying component 41 and the second driven component 62, ensuring the transmission stability between the conveying component 41 and the second driven component 62, thereby ensuring the conveying stability of the seedling by the conveying component 41.

[0043] In some settings, please refer to Figure 1 , Figure 2 and Figure 3 To ensure the lifting stability of the lifting assembly 30, multiple sets of the first transmission assembly 50 can be provided, with these multiple sets of first transmission assemblies 50 spaced apart along the second direction Y. To ensure the conveying stability of the clinker, multiple sets of the second transmission assembly 60 and conveying member 41 are also provided, with these multiple sets of second transmission assemblies 60 and conveying member 41 spaced apart along the third direction Z. To ensure the support stability of the support assembly 20 for the seedlings, the support assembly 20 may include first support members 21 and second support members 22 spaced apart along the second direction Y. The first support members 21 and second support members 22 can support different positions of the seedlings in the second direction Y, thereby improving the support stability of the seedlings. Optionally, multiple sets of first transmission assemblies 50 are disposed between the first support members 21 and the second support members 22, and multiple sets of second transmission assemblies 60 and conveying member 41 are also disposed between the first support members 21 and the second support members 22, thereby reducing the overall structural size of the conveying device.

[0044] In some embodiments, please refer to Figure 2 and Figure 3The conveying device also includes a connecting assembly 70 connecting the base 10 and the lifting platform 31. The connecting assembly 70 includes a first connecting member 71 fixedly connected to the base 10, a second connecting member 72 fixedly connected to the lifting platform 31, and a third connecting member 73 connecting the first connecting member 71 and the second connecting member 72. The first connecting member 71 and the third connecting member 73 are rotatably connected in the second direction Y, and the second connecting member 72 and the third connecting member 73 are rotatably connected in the second direction Y.

[0045] During the lifting process of the lifting platform 31, the conveying component 40 changes from being spaced from the sapling to coming into contact with the sapling, thereby exerting a force on the sapling. At the same time, the sapling also exerts a force on the conveying component 40. To improve the stability of the lifting platform 31, the conveying device also includes a connecting component 70 connected between the base 10 and the lifting platform 31. The connection between the base 10 and the lifting platform 31 via the connecting component 70 can improve the stability of the lifting platform 31.

[0046] Furthermore, to make the force exerted by the conveyor 41 on the seedling more gentle, the first connector 71, the second connector 72, and the third connector 73 in the connecting assembly 70 are rotatably connected around the second direction Y. This allows the lifting platform 31 to rotate a certain amount around the second direction Y during the contact process between the conveyor 41 and the seedling. In other words, after the conveyor 41 contacts the seedling, the seedling exerts a certain force on the conveyor 41, and the conveyor 41 transmits the force to the lifting platform 31. The lifting platform 31 can then sway a certain amount in a plane perpendicular to the first direction X to alleviate the force exerted by the seedling on the conveyor 41. At the same time, this makes the force exerted by the conveyor 41 on the seedling more gentle, reduces damage to the seedling, and ensures the survival rate of the seedling after transplanting.

[0047] In some embodiments, please refer to Figure 2 and Figure 3 Multiple first connectors 71, second connectors 72, and third connectors 73 are provided, and these multiple first connectors 71, second connectors 72, and third connectors 73 are spaced apart within the projection of the lifting platform 31 in the first direction X. The connecting assembly 70 also includes a fourth connector 74, which is connected between adjacent third connectors 73, and the fourth connector 74 and the third connector 73 are rotatably connected around the second direction Y.

[0048] Considering that the lifting platform 31 has a certain size and area, multiple first connectors 71, second connectors 72 and third connectors 73 are provided. The multiple first connectors 71, second connectors 72 and third connectors 73 are distributed at intervals within the projection of the lifting platform 31 in the first direction X, so as to form multiple connection points between the lifting platform 31 and the base 10, thereby improving the stability of the lifting platform 31.
