[0002] Take Chuxiong, Yunnan as an example. In the fragmented tobacco planting area, tobacco transplanting is still mainly manual transplanting, supplemented by small semi-automatic transplanting machinery, because the area available for tobacco planting is widely distributed, the area of ​​a single area is small, and the transportation between areas is inconvenient. The transplanting efficiency is low, and it is difficult to use large transplanting machinery to achieve efficient transplanting. In addition, during the working process of the semi-automatic transplanting machinery, a large number of personnel are required to manually send the tobacco seedlings into the semi-automatic transplanting machinery one by one. If the operation time is too long, it will cause fatigue to the personnel, often resulting in the phenomenon of missing seedlings. In addition, due to the limitation of human physiological reaction speed, the transplanting speed is low, only about 1 plant / second, which is only 2-5 times that of manual planting.

In addition, the terms "first" and "second" are only used to distinguish in the description and have no special meaning.

[0049] The following is based on the attached Figure 1 To Attachment Fig.10 The paper pot type transplanter provided by the present invention is introduced. Specifically, in the present invention, the paper pot refers to a chain paper pot, which includes a plurality of seedling hole structures connected in sequence, and each seedling hole structure can accommodate a substrate (ie, soil) and a single seedling.

[0050] like Figure 1 As shown, in this embodiment, the paper pot transplanter mainly includes a seedling storage mechanism 1, a seedling support mechanism 2, a soil breaking mechanism 3, a seedling emergence mechanism 4, a soil covering mechanism 5 and a compacting mechanism 6. Among them, the seedling storage mechanism 1 is provided with a supporting plate 11, which can play the role of limiting the support chain paper pot during the transplanting process. The seedling support mechanism 2 is connected to the seedling storage mechanism 1, and the seedling support mechanism 2 forms a tobacco seedling channel. The above-mentioned seedling hole structure can enter the tobacco seedling channel one by one, and under the action of the seedling support mechanism 2, the seedling hole structure and the individual seedlings in the seedling hole structure are kept in a vertical posture.

[0051] The soil-breaking mechanism 3 is arranged at the bottom of the paper pot transplanter. When the paper pot transplanter performs transplanting operation, the soil-breaking mechanism 3 can invade the soil surface and form a transplanting ditch. The seedling-emerging mechanism 4 is connected to the seedling-supporting mechanism 2, which is connected to the tobacco seedling channel. The seedling hole structure can move through the seedling-supporting mechanism 2 and the seedling-emerging mechanism 4 in sequence, and fall into the transplanting ditch after leaving the seedling-emerging mechanism 4. The seedling hole structure is set at a preset distance from the bottom surface of the transplanting ditch, thereby limiting the falling distance of the seedling hole structure and avoiding the phenomenon of individual seedlings tipping over during the falling process.

[0052] The soil covering mechanism 5 is connected to the end of the seedling emergence mechanism 4 away from the seedling supporting mechanism 2, and can move the soil at the edge of the transplanting ditch, so that the soil moves toward the middle of the transplanting ditch to form a covering soil layer, thereby covering the seedling hole structure. Subsequently, the compacting mechanism 6 is used to further compact the covering soil layer, thereby fixing the seedling hole structure and further preventing the phenomenon of individual seedlings from falling over.

[0053] When operating the paper pot transplanter to perform transplanting operations, illustratively, the chain paper pot is first placed on the seedling storage mechanism 1, and one end of the chain paper pot is passed through the seedling support mechanism 2 and the seedling emergence mechanism 4, and the paper pot transplanter is moved at the same time to form a transplanting ditch on the soil surface. When the seedling emergence mechanism 4 moves to the top of the transplanting ditch, a seedling hole structure located at the end of the chain paper pot is dropped through the seedling emergence mechanism 4 until it enters the transplanting ditch and contacts the soil. Subsequently, as the paper pot transplanter moves, a tight covering soil layer is formed by the covering mechanism 5 and the compacting mechanism 6, thereby fixing the seedling hole structure, pulling the chain paper pot, and then pulling the seedling hole structure through the seedling support mechanism 2 and the seedling emergence mechanism 4 one by one, forming a continuous transplanting process.

[0054] Through the paper pot transplanter, a transplanting ditch suitable for the planting needs of individual seedlings can be formed, and the individual seedlings planted in the chain paper pots can be quickly placed in the transplanting ditch in a vertical posture through the seedling supporting mechanism 2 and the seedling emerging mechanism 4, and finally a compact covering soil layer is formed through the soil covering mechanism 5 and the compacting mechanism 6, thereby continuously completing the steps of trenching, transplanting, soil covering and compacting, getting rid of the speed limitation of manual seedling removal and delivery, and greatly improving the transplanting efficiency of tobacco seedlings.

[0055] Specifically, Figure 1 , Figure 2As shown, in this embodiment, the seedling storage mechanism 1, the seedling support mechanism 2, the seedling emergence mechanism 4, the soil covering mechanism 5 and the compacting mechanism 6 are connected in sequence, and the soil breaking mechanism 3 is arranged below the seedling support mechanism 2 and the seedling emergence mechanism 4, and can penetrate the soil surface (the dotted line indicates the soil surface) to form a transplanting ditch when the paper pot type transplanter is moved. In addition, the paper pot type transplanter also includes a traction mechanism 7, which is connected to the end of the seedling storage mechanism 1 away from the seedling support mechanism 2. The traction mechanism 7 is used for people to grasp or connect to power equipment, and the traction mechanism 7 includes a traction roller 71, which can abut against the soil surface to reduce the movement resistance of the paper pot type transplanter, thereby reducing the physical burden when transferring the paper pot type transplanter or performing transplanting operations, so that the paper pot type transplanter is more suitable for fragmented planting areas such as mountains and hills.

[0056] Preferably, continue to refer to Figure 1 , Figure 2 As shown, the traction mechanism 7 mainly includes a traction handle 72 and a sleeve 73. The upper end of the sleeve 73 is open. The traction handle 72 is T-shaped and is arranged at the top of the traction mechanism 7, and its vertical end can be inserted into the sleeve 73. One of the sleeve 73 and the traction handle 72 is provided with at least one through hole, and the other is provided with at least two through holes. The adjustment bolt can pass through the through holes located in the sleeve 73 and the traction handle 72 at the same time, so that the traction handle 72 is inserted and fixed in the sleeve 73 at a preset depth. When in use, by selectively passing the adjustment bolt through the through holes located at different positions on the sleeve 73 or the traction handle 72, the traction handle 72 can be inserted and fixedly connected to the sleeve 73 at different depths, so as to adjust the height distance between the top of the traction handle 72 and the soil surface, thereby meeting the connection requirements of different power equipment, or meeting the grasping requirements of people with different heights and different postures (upright posture or bent posture), reducing the labor burden, and improving the work efficiency of transplanting.

[0057] like Figure 2 , Figure 3 As shown, in this embodiment, the traction mechanism 7 also includes a traction connection plate 74, a roller support rod 75 and a roller adjustment rod 76. Among them, the traction connection plate 74 is connected and arranged between the sleeve 73 and the seedling storage mechanism 1, so as to realize the fixed connection between the traction mechanism 7 and the seedling storage mechanism 1, the soil breaking mechanism 3 and other structures. The roller straight rod and the roller adjustment rod 76 are connected to the traction roller 71 together, so as to play the effect of installing the traction roller 71. In addition, the upper end of the roller support rod 75 is inserted into the lower end opening of the sleeve 73, and the lower end thereof is fixedly connected to the traction roller 71. The upper end of the roller adjustment rod 76 is connected to the traction connection plate 74, and the position is adjustable along the traction connection plate 74, so that the traction roller 71 and the soil breaking mechanism 3 are connected in an adjustable distance along the height direction, so as to achieve the effect of adjusting the depth of the soil breaking mechanism 3 invading the soil surface.

[0058] Exemplarily, in this embodiment, a comb-shaped notch 741 is provided on the traction connecting plate 74, and the comb-shaped notch 741 forms a plurality of buckle positions, and the plurality of buckle positions are arranged in a height direction. A buckle portion is provided at the upper end of the roller adjustment rod 76, and the buckle portion can be selectively inserted into the buckle position, so that the traction roller 71 and the traction connecting plate 74 are fixed according to a preset spacing, so that the soil-breaking mechanism 3 can penetrate the soil surface according to a preset depth. When it is necessary to deepen the depth of penetration into the soil surface, the buckle portion can be moved and inserted and connected with the buckle position at a higher position. At this time, the distance between the traction roller 71 and the soil-breaking mechanism 3 in the height direction is reduced, and the soil-breaking mechanism 3 will penetrate further into the soil surface. On the contrary, when the buckle portion is inserted and connected with the buckle position at a lower position, the distance between the traction roller 71 and the soil-breaking mechanism 3 in the height direction increases, and the depth of penetration of the soil-breaking mechanism 3 on the soil surface is reduced. Therefore, by adjusting the height distance between the traction roller 71 and the soil-breaking mechanism 3, the depth of the soil-breaking mechanism 3 penetrating into the soil surface can be adjusted to form transplanting trenches of different depths to meet different specific transplanting needs.

[0059] like Figure 4 As shown, the supporting plate 11 of the seedling storage mechanism 1 is provided with a plurality of circular hollow structures 111, which can separate part of the matrix and water contained in the seedling hole structure at the seedling storage mechanism 1, so that the excess matrix can be directly discharged, avoiding blockage of the seedling supporting mechanism 2, the seedling emergence mechanism 4 and other positions by excessive matrix, and is also beneficial to reducing the weight and material consumption of the entire fuselage.

[0060] Preferably, in this embodiment, the seedling supporting mechanism 2 includes a guide surface and at least one protruding structure 24, the guide surface is used to support the chain paper pot, and the chain paper pot can slide from the seedling storage mechanism 1 through the guide surface and enter the seedling emergence mechanism 4. The protruding structure 24 is arranged on the guide surface and can slide against the side of the chain paper pot to adjust or maintain the individual seedlings to a vertical posture.

[0061] Specifically, in this embodiment, the seedling supporting mechanism 2 includes a bottom plate 21, a side plate 22, a first connecting plate 23, a first protrusion 241 and a second protrusion 242. The bottom plate 21 and the seedling storage mechanism 1 are fixedly connected by a square tube, and the side plate 22 and other structures are fixed on the bottom plate 21, so as to avoid the misalignment movement between the seedling storage mechanism 1 and the seedling supporting mechanism 2, and ensure the stable movement of the chain paper pot during the normal transplanting process. The seedling storage mechanism 1, the bottom plate 21 and the seedling emergence mechanism 4 are arranged from high to low, and the end of the bottom plate 21 close to the seedling storage mechanism 1 is higher than the end close to the seedling emergence mechanism 4, so that the chain paper pot can further slide down into the seedling emergence mechanism 4 under the action of gravity. The two opposite edges of the bottom plate 21 close to the end of the seedling storage mechanism 1 are each connected to a side plate 22, and the side plate 22 is connected to the bottom plate 21 in an upwardly bent posture, so as to form a groove structure between the bottom plate 21 and the two side plates 22, so as to prevent the chain paper pot from falling out of the seedling supporting mechanism 2.

[0062] The first protrusion 241 and the second protrusion 242 are arranged on the first connecting plate 23, and the first connecting plate 23 is installed above the bottom plate 21. The first connecting plate 23 and part of the surface of the bottom plate 21 constitute the above-mentioned guide surface, which can support the chain paper bowl. The first protrusion 241 and the second protrusion 242 both adopt a C-shaped structure, which has an abutting arc surface, and the abutting arc surface is used to slide against the chain paper bowl, which can play a better guiding and supporting effect, and avoid the phenomenon that the edge of the first protrusion 241 or the second protrusion 242 cuts and tears the chain paper bowl. The first protrusion 241 can slide against one side of the chain paper bowl, and the second protrusion 242 can slide against the other side of the chain paper bowl. A curved or straight tobacco seedling channel is defined between the first protrusion 241 and the second protrusion 242, thereby playing a supporting effect.

[0063] Preferably, in this embodiment, along the length direction and thickness direction of the chain paper pot, the first protrusion 241 and the second protrusion 242 are staggered to form a bent tobacco seedling channel, so that the chain paper pot forms an S-shaped extension state under the action of the first protrusion 241 and the second protrusion 242, which can not only achieve a better seedling support effect, but also form a certain resistance to the sliding of the chain paper pot, preventing the phenomenon of too small resistance and uncontrolled sliding of the chain paper pot. At the same time, a detachable connection method can be adopted between the first connecting plate 23 and the bottom plate 21, so that the first connecting plate 23 (and the protrusion structure 24 arranged on the first connecting plate 23) can be replaced according to different transplanting needs, and a straightening effect can be achieved for tobacco seedlings of different sizes or types or other plant seedlings.

[0064] It should be noted that, in some embodiments, protrusion structures 24 with other shapes or other relative position relationships may be used. As long as a tobacco seedling channel with a seedling-supporting effect can be formed, it falls within the scope of protection of the present invention.

[0065] Optionally, in some embodiments, the paper pot transplanter also includes an inclined plug plate, which can be inserted between the support plate 11 and the chain paper pot, so as to increase the height of the chain paper pot, until the chain paper pot is not lower than the first connecting plate 23, so as to facilitate the chain paper pot to slide from the support plate 11 into the seedling supporting mechanism 2. When the transfer is required, the inclined plug plate can be taken out from between the support plate 11 and the chain paper pot, so as to increase the resistance of the chain paper pot to slide into the seedling supporting mechanism 2, thereby preventing the chain paper pot from sliding accidentally. Preferably, when the inclined plug plate is placed on the support plate 11, its top surface is not lower than the first connecting plate 23, and the end of the support plate 11 close to the first connecting plate 23 is set lower than the first connecting plate 23, so that the inclined plug plate forms a switch effect, so that the chain paper pot can slide normally into the seedling supporting mechanism 2 only when the inclined plug plate is inserted.

[0066] Continue to refer to Figure 5 As shown, in some embodiments, the seedling supporting mechanism 2 further includes two guide plates 25, which are mounted on the bottom plate 21 and arranged on one side of the second protrusion 242 close to the seedling emergence mechanism 4, defining a vertical seedling channel, and the spacing between the two guide plates 25 is small, thereby ensuring that the straightened single seedling can quickly enter the vertical seedling channel and ensure that it will not fall again before entering the seedling emergence mechanism 4. Preferably, along the direction from the seedling supporting mechanism 2 to the seedling emergence mechanism 4, the spacing between the two guide plates 25 gradually decreases to form a trumpet shape, which can conveniently accommodate the seedling hole structure.

[0067] Furthermore, the above-mentioned circular hollow structure 111 is also provided in the portion of the bottom plate 21 between the two guide plates 25, which can also achieve the effect of discharging part of the matrix and moisture, and is also beneficial to reducing the weight and material usage of the fuselage.

[0068] like Figure 6 , Figure 7 and Figure 8As shown, in this embodiment, the soil-breaking mechanism 3 includes a soil-breaking member 31 and a ditching member 32. Along the moving direction of the paper pot transplanter, the soil-breaking member 31 is arranged in front of the ditching member 32, and the ditching member 32 is fixedly installed at the bottom of the seedling-supporting mechanism 2. The soil-breaking member 31 has a soil-breaking end for invading the soil surface, which can loosen and break the harder soil blocks and reduce the resistance to movement. The ditching member 32 is formed by connecting two plates arranged in the vertical direction. The ends of the two plates are welded and connected to form a sharper part and connected with the above-mentioned soil-breaking member 31, and the distance between the two plates gradually increases in the direction away from the soil-breaking member 31, so that the soil can be moved to form a transplanting ditch. Preferably, in this embodiment, the soil-breaking member 31 adopts a plate with a triangular tip, and the triangular tip constitutes the above-mentioned soil-breaking end. In addition, the plate is arranged at a certain angle to the horizontal plane when in use, and can lift the soil and stones in the soil upward, so as to achieve a better soil-breaking effect.

[0069] like Figure 7 , Figure 8 As shown, in this embodiment, the seedling mechanism 4 includes a first connecting arm 41 and a second connecting arm 42. One end of the first connecting arm 41 is connected to the seedling supporting mechanism 2, and the other end is used to connect a part of the soil covering mechanism 5 and a part of the compacting mechanism 6. One end of the second connecting arm 42 is also connected to the seedling supporting mechanism 2, and the other end is used to connect another part of the soil covering mechanism 5 and another part of the compacting mechanism 6. The first connecting arm 41 and the second connecting arm 42 are arranged at a certain distance, and a seedling emergence piece 43 is also arranged between the two. The seedling emergence piece 43, the first connecting arm 41 and the second connecting arm 42 define a seedling emergence groove, and the length of the seedling emergence piece 43 is less than that of the first connecting arm 41 and the second connecting arm 42, thereby forming a seedling drop mouth 40, and the seedling hole structure can move along the seedling emergence groove until it falls from the seedling drop mouth 40 to the transplanting ditch.

[0070] Specifically, in this embodiment, taking the tobacco seedlings of flue-cured tobacco as an example, in the paper pot type transplanter, the spacing between the first connecting arm 41 and the second connecting arm 42 is not less than 35 mm, so as to ensure that the seedling hole structure can smoothly enter the seedling groove. The width of the above-mentioned ditching member 32 is not less than 40 mm, so as to form a transplanting ditch that meets the requirements of flue-cured tobacco transplanting. In addition, based on the requirement of 50-60 cm spacing between two adjacent seedling hole structures when transplanting flue-cured tobacco, the length of the seedling piece 43 is set between 5-10 cm, so as to ensure that the chain paper pot can be normally tightened after the seedlings fall, and avoid the phenomenon of stuck seedlings.

[0071] Preferably, in this embodiment, the distance between the seedling emergence piece 43 and the bottom surface of the transplanting groove is reduced along the direction away from the seedling supporting mechanism 2 to control the falling distance of the seedling hole structure and prevent the phenomenon of individual seedlings tipping over during the seedling dropping process.

[0072] like Fig. 9 As shown, in this embodiment, the soil covering mechanism 5 includes two soil covering plates 51 that are arranged to roll, and the spacing between the two soil covering plates 51 is reduced in the direction away from the soil breaking mechanism 3, so as to push the soil on both sides of the transplanting ditch into the transplanting ditch to form a covering soil layer. The rolling setting enables the soil covering plate 51 to roll against the soil, greatly reducing the resistance during soil covering, and the edge of the soil covering plate 51 can invade the soil surface, thereby ensuring that the amount of soil moved can form a covering soil layer of sufficient thickness, which has a good wrapping effect on the root system and will not cause a large labor burden on the transplanting operation. Preferably, the two soil covering plates 51 are installed in a movable setting in the axial direction, so as to change the spacing between the two soil covering plates 51. At the same time, the soil covering plate 51 is also connected to an elastic member, and the elastic force generated by the elastic member makes the spacing between the two soil covering plates 51 tend to the above-mentioned reduced setting in the direction away from the soil breaking mechanism 3. During use, when encountering stones or larger seedling hole structures, the resistance encountered by the soil covering plate 51 will overcome the elastic force of the elastic member, causing the soil covering plate 51 to rotate around the rotation axis, achieving a certain avoidance effect and further reducing the resistance during transplanting operations.

[0073] Exemplarily, in the present embodiment, each soil covering plate 51 is sleeved on a stud 52 in a gap assembly manner, and each stud 52 is provided with two limit nuts 53, and the soil covering plate 51 is arranged between the two limit nuts 53. At the same time, the spacing between the two limit nuts 53 is greater than the thickness of the soil covering plate 51, so that the axial direction of the soil covering plate 51 can be movable, thereby realizing the change of the distance between the two soil covering plates 51. Of course, in some embodiments, the axial movement of the soil covering plate 51 can also be realized by setting a rotating connection structure such as a rotating shaft, which also belongs to the scope of protection of the present invention. Optionally, the soil covering plate 51 has a curved plate surface, and the spacing between the two soil covering plates 51 is reduced along the direction close to the stud 52, thereby further optimizing the movement effect on the soil and increasing the amount of soil moved.

[0074] It should be noted that, in some embodiments, the rotating shaft can be installed on the first connecting arm 41 and the second connecting arm 42 through an adapter plate, and in some other embodiments, the rotating shaft can also be directly installed on the first connecting arm 41 and the second connecting arm 42, or installed through other structures. Therefore, the specific installation method of the rotating connecting structure such as the rotating shaft is not limited in the present invention, as long as the covering plate 51 rotates around the rotating shaft, the overall spacing or the local spacing between the two covering plates 51 can be changed. Similarly, the elastic member can also be set in a variety of ways such as a spring and a spring sheet, so the specific structure and specific installation method of the elastic member are not limited in the present invention.

[0075] Continue to refer to Fig. 9As shown, in this embodiment, the compaction mechanism 6 includes two compaction rollers 61, and the two compaction rollers 61 are arranged at a certain inclination angle, so that the distance between the two compaction rollers 61 gradually decreases from top to bottom, thereby avoiding structures such as the top leaves of individual seedlings and also achieving a good compacting effect on the covering soil layer.

[0076] like Fig.10 As shown, in this embodiment, the paper pot transplanter also includes a lifting handle 8, which is fixedly connected to the center of gravity of the paper pot transplanter, so that a single person can lift and move the paper pot transplanter conveniently, further facilitating the application and promotion of the paper pot transplanter in mountainous areas, hilly areas and the like.

[0077] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the embodiments of the present invention. For those skilled in the art, various obvious changes, readjustments and substitutions can be made without departing from the protection scope of the present invention. It is not necessary and impossible to list all the embodiments here. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the claims of the present invention.
