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

[0049] Below according to the drawings Figure 1 to the drawings Figure 10 Introduce the paper pot type transplanting machine provided by the utility model. Specifically, in the utility model, the paper pot refers to chain type paper pot, which comprises a plurality of sequentially connected seedling hole structures, and each seedling hole structure can accommodate substrate (i.e. soil) and single seedling.

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

[0051] The soil breaking mechanism 3 is arranged at the bottom of the paper-pot type transplanting machine, and can penetrate into the soil surface and form a transplanting ditch when the paper-pot type transplanting machine is used for transplanting operation. The seedling taking mechanism 4 is connected to the seedling supporting mechanism 2 and is arranged in communication with the tobacco seedling channel. The seedling hole structure can move through the seedling supporting mechanism 2 and the seedling taking mechanism 4 in sequence and fall into the transplanting ditch after leaving the seedling taking mechanism 4. The seedling hole structure is arranged at a preset distance from the bottom surface of the transplanting ditch, so as to limit the falling distance of the seedling hole structure and avoid the phenomenon of single seedling falling during the falling process.

[0052] The soil covering mechanism 5 is connected to the end of the seedling taking mechanism 4 away from the seedling supporting mechanism 2, and can move the soil located at the edge of the transplanting ditch, so as to move the soil towards the middle part of the transplanting ditch and form a covering soil layer to cover the seedling hole structure. Then, the compacting mechanism 6 is used to further compact the covering soil layer, so as to fix the seedling hole structure and further prevent the phenomenon of single seedling falling.

[0053] When the paper-pot type transplanting machine is used for transplanting operation, for example, the chain paper pot is first placed on the seedling storing mechanism 1, and one end of the chain paper pot is passed through the seedling supporting mechanism 2 and the seedling taking mechanism 4. Then, the paper-pot type transplanting machine is moved to form a transplanting ditch on the soil surface. When the seedling taking mechanism 4 moves above the transplanting ditch, one seedling hole structure at the end of the chain paper pot falls through the seedling taking mechanism 4 and enters the transplanting ditch and contacts the soil. Then, with the movement of the paper-pot type transplanting machine, the soil covering mechanism 5 and the compacting mechanism 6 form a compact covering soil layer, so as to fix the seedling hole structure and pull the chain paper pot, and then pull the seedling hole structure through the seedling supporting mechanism 2 and the seedling taking mechanism 4 one by one, to form a continuous transplanting process.

[0054] Through the paper-pot type transplanting machine, a transplanting ditch suitable for the planting of single seedlings can be formed, and the single seedlings planted in the chain paper pot can be quickly placed into the transplanting ditch in a vertical posture through the seedling supporting mechanism 2 and the seedling taking mechanism 4, and finally a compact covering soil layer is formed through the soil covering mechanism 5 and the compacting mechanism 6, so as to continuously complete the steps of ditching, transplanting, soil covering and compacting, and the speed limitation of manual seedling taking and seedling sending is eliminated, and the transplanting efficiency of tobacco seedlings is greatly improved.

[0055] Specifically, as Figure 1 , Figure 2As shown, in the embodiment, the seedling storage mechanism 1, the seedling supporting mechanism 2, the seedling emergence mechanism 4, the soil covering mechanism 5 and the soil compacting mechanism 6 are sequentially connected, and the soil breaking mechanism 3 is arranged below the seedling supporting mechanism 2 and the seedling emergence mechanism 4, which can invade the soil surface (the dotted line represents the soil surface) to form a transplanting trench when the paper-pot type transplanting machine is moved. In addition, the paper-pot type transplanting machine further comprises a traction mechanism 7 connected to the seedling storage mechanism 1 away from the seedling supporting mechanism 2. The traction mechanism 7 is used for holding or connecting to a power device, and the traction mechanism 7 comprises a traction roller 71 which can abut the soil surface to reduce the moving resistance of the paper-pot type transplanting machine, thereby reducing the physical burden when the paper-pot type transplanting machine is moved or transplanted, so that the paper-pot type transplanting machine is more suitable for fragmented planting areas such as mountains and hills.

[0056] Preferably, continuing to refer to Figure 1 、 Figure 2 As shown, the traction mechanism 7 mainly comprises 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 arranged at the top of the traction mechanism 7, and the 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, and the adjusting bolt can pass through the through holes in the sleeve 73 and the traction handle 72 at the same time, so as to insert and fix the traction handle 72 in the sleeve 73 at a predetermined depth. In use, by selectively passing the adjusting bolt through the through holes 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 end of the traction handle 72 and the soil surface, thereby meeting the connection needs of different power devices, or meeting the holding needs of personnel of different heights and different postures (standing posture or bending posture), achieving the reduction of labor burden and improving the work efficiency of transplanting.

[0057] As shown in Figure 2 、 Figure 3 In the embodiment, the traction mechanism 7 further comprises a traction connecting plate 74, a roller supporting rod 75 and a roller adjusting rod 76. The traction connecting plate 74 is connected between the sleeve 73 and the seedling storage mechanism 1, realizing the fixed connection of the traction mechanism 7 and the seedling storage mechanism 1, the soil breaking mechanism 3 and the like. The roller straight rod and the roller adjusting rod 76 are commonly connected to the traction roller 71, achieving the effect of installing the traction roller 71. In addition, the upper end of the roller supporting rod 75 is inserted into the lower end opening of the sleeve 73, and the lower end is fixedly connected with the traction roller 71. The upper end of the roller adjusting rod 76 is connected to the traction connecting plate 74 and is adjustably arranged along the position between the traction connecting plate 74, so that the traction roller 71 and the soil breaking mechanism 3 are adjustably connected in the height direction, which can achieve the effect of adjusting the depth of the soil breaking mechanism 3 invading the soil surface.

[0058] Exemplarily, in the present embodiment, the traction connecting plate 74 is provided with a comb-shaped notch 741, which forms a plurality of buckle positions arranged in the height direction. The upper end of the roller adjusting rod 76 is provided with a buckle part, which can be selectively inserted into the buckle position, so as to fix the traction roller 71 and the traction connecting plate 74 at a preset interval, so that the soil breaking mechanism 3 can penetrate the soil surface at a preset depth. When it is necessary to deepen the depth of penetration into the soil surface, the buckle part can be moved 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 penetrates the soil surface further. Conversely, when the buckle part is 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 is increased, and the depth of penetration of the soil breaking mechanism 3 into 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 penetration of the soil breaking mechanism 3 into the soil surface can be adjusted, and a transplanting trench of different depth can be formed to meet different specific transplanting needs.

[0059] As shown in Figure 4 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 substrate and water contained in the seedling hole structure at the seedling storage mechanism 1, so that the excess substrate is directly discharged, avoiding excessive substrate from causing blockage at the seedling supporting mechanism 2, the seedling discharging mechanism 4 and the like, and also being beneficial to reduce the weight and material consumption of the entire machine body.

[0060] Preferably, in the present embodiment, the seedling supporting mechanism 2 comprises a guide surface and at least one protruding structure 24, the guide surface being used to support the chain paper pots, and the chain paper pots can slide through the guide surface from the seedling storage mechanism 1 and enter the seedling discharging mechanism 4. The protruding structure 24 is arranged on the guide surface and can slide against the side surface of the chain paper pot to adjust or maintain the single seedling to an upright posture.

[0061] Specifically, in the embodiment, the seedling supporting mechanism 2 comprises a bottom plate 21, side plates 22, a first connecting plate 23, first protrusions 241 and second protrusions 242. The bottom plate 21 is fixedly connected with the seedling storing mechanism 1 through square tubes, and the side plates 22 are fixedly arranged on the bottom plate 21, so as to avoid dislocation between the seedling storing mechanism 1 and the seedling supporting mechanism 2 and ensure stable movement of the chain paper pots in the normal transplanting process. The seedling storing mechanism 1, the bottom plate 21 and the seedling supporting mechanism 4 are arranged from high to low, and the end of the bottom plate 21 close to the seedling storing mechanism 1 is higher than the end close to the seedling supporting mechanism 4, so that the chain paper pots can further slide into the seedling supporting mechanism 4 under the action of gravity. The opposite edges of the end of the bottom plate 21 close to the seedling storing mechanism 1 are respectively connected with a side plate 22, and the side plates 22 are connected to the bottom plate 21 in an upwardly bent manner, so as to form a groove structure between the bottom plate 21 and the two side plates 22 and avoid the chain paper pots from falling out of the seedling supporting mechanism 2.

[0062] The first protrusions 241 and the second protrusions 242 are arranged on the first connecting plate 23, and the first connecting plate 23 is arranged above the bottom plate 21. The first connecting plate 23 and part of the surface of the bottom plate 21 constitute the guiding surface, which can support the chain paper pots. The first protrusions 241 and the second protrusions 242 both adopt C-shaped structures, which have abutting arc surfaces for slidingly abutting the chain paper pots, so as to achieve better guiding and seedling supporting effects and avoid cutting or tearing the chain paper pots by the edges of the first protrusions 241 or the second protrusions 242. The first protrusions 241 can slidingly abut one side of the chain paper pots, and the second protrusions 242 can slidingly abut the other side of the chain paper pots. The first protrusions 241 and the second protrusions 242 define a bending or straight tobacco seedling channel therebetween, so as to achieve the seedling supporting effect.

[0063] Preferably, in the embodiment, the first protrusions 241 and the second protrusions 242 are staggered between each other along the length direction and the thickness direction of the chain paper pots, so as to form a bending tobacco seedling channel. The chain paper pots form an S-shaped extension state under the action of the first protrusions 241 and the second protrusions 242, which not only achieves better seedling supporting effect, but also forms certain resistance to the sliding of the chain paper pots, so as to prevent the chain paper pots from sliding uncontrollably due to too small resistance. Meanwhile, the first connecting plate 23 and the bottom plate 21 can be detachably connected, so that the first connecting plate 23 (and the protrusion structures 24 arranged on the first connecting plate 23) can be replaced according to different transplanting needs, so as to support different sizes or different types of tobacco seedlings or other plant seedlings.

[0064] It should be noted that in some embodiments, other shapes or other relative position relationships of the protruding structure 24 can also be adopted as long as the tobacco seedling channel with the seedling supporting effect can be formed, which falls within the scope of the present application.

[0065] Optionally, in some embodiments, the paper pot type transplanting machine further comprises an inclined plate which can be inserted between the supporting 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, facilitating the chain paper pot to slide from the supporting plate 11 into the seedling supporting mechanism 2. When it is necessary to be transferred, the inclined plate can be removed from between the supporting plate 11 and the chain paper pot, increasing the resistance of the chain paper pot to slide into the seedling supporting mechanism 2, thereby preventing the chain paper pot from accidentally sliding. Preferably, when the inclined plate is placed on the supporting plate 11, the top surface thereof is not lower than the first connecting plate 23, and the end portion of the supporting plate 11 close to the first connecting plate 23 is lower than the first connecting plate 23, so that the inclined plate forms an on-off effect, so that the chain paper pot can normally slide into the seedling supporting mechanism 2 only when the inclined plate is inserted.

[0066] Continuing to refer to Figure 5 In some embodiments, the seedling supporting mechanism 2 further comprises two guide plates 25 which are installed on the bottom plate 21 and are arranged on the side close to the seedling emergence mechanism 4 of the second protrusion 242, thereby defining a seedling standing channel, and the distance between the two guide plates 25 is small, so as to ensure that the single seedling which has been righted can quickly enter the seedling standing channel, thereby preventing it from falling again before entering the seedling emergence mechanism 4. Preferably, the distance between the two guide plates 25 gradually decreases in the direction from the seedling supporting mechanism 2 to the seedling emergence mechanism 4, forming a horn shape, which can conveniently accommodate the seedling hole structure.

[0067] Further, the part of the bottom plate 21 between the two guide plates 25 is also provided with the above-mentioned circular hollow structure 111, which can also achieve the effect of discharging part of the substrate and water, and is also beneficial to reduce the weight and material consumption of the machine body.

[0068] As Figure 6 , Figure 7 and Figure 8As shown, in the present embodiment, the soil breaking mechanism 3 comprises a soil breaking piece 31 and a ditching piece 32. The soil breaking piece 31 is arranged in front of the ditching piece 32 along the moving direction of the paper-pot type transplanting machine, and the ditching piece 32 is fixedly installed at the bottom of the seedling supporting mechanism 2. The soil breaking piece 31 has a soil breaking end for penetrating into the soil surface, which can loosen and break the hard soil blocks to reduce the moving resistance. The ditching piece 32 is connected by two plate pieces arranged in the vertical direction. The end portions of the two plate pieces are welded to form a sharp part and are connected with the soil breaking piece 31. The distance between the two plate pieces gradually increases in the direction away from the soil breaking piece 31, which can move the soil to form a transplanting ditch. Preferably, in the present embodiment, the soil breaking piece 31 is a plate piece with a triangular tip, which constitutes the soil breaking end. The plate piece is arranged at a certain angle with the horizontal plane during use, which can lift the soil and stones in the soil upward to achieve a better soil breaking effect.

[0069] As shown in Figure 7 , Figure 8 As shown, in the present embodiment, the seedling falling mechanism 4 comprises 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 apart, and a seedling falling piece 43 is arranged between them. The seedling falling piece 43, the first connecting arm 41 and the second connecting arm 42 define a seedling falling groove, and the length of the seedling falling piece 43 is less than that of the first connecting arm 41 and the second connecting arm 42, thereby forming a seedling falling opening 40. The seedling hole structure can move along the seedling falling groove until it falls into the transplanting ditch from the seedling falling opening 40.

[0070] Specifically, in the present embodiment, taking the tobacco seedlings of flue-cured tobacco as an example, the distance between the first connecting arm 41 and the second connecting arm 42 in the paper-pot type transplanting machine is not less than 35 mm, thereby ensuring that the seedling hole structure can smoothly enter the seedling falling groove. The width of the above-mentioned ditching piece 32 is not less than 40 mm, thereby forming a transplanting ditch that meets the needs of flue-cured tobacco transplanting. Moreover, based on the requirement that the distance between two adjacent seedling hole structures is 50-60 cm when transplanting flue-cured tobacco, the length of the seedling falling piece 43 is set to be between 5-10 cm, thereby ensuring that the chain paper-pot can be normally tightened after seedling falling, and avoiding the phenomenon of seedling jamming.

[0071] Preferably, in the present embodiment, the distance between the seedling falling piece 43 and the bottom surface of the transplanting ditch decreases in the direction away from the seedling supporting mechanism 2, thereby controlling the falling distance of the seedling hole structure and preventing the phenomenon of single seedling falling during seedling falling.

[0072] As Figure 9 shown in the drawings, in the present embodiment, the covering mechanism 5 comprises two covering discs 51 arranged in rolling manner, and the distance between the two covering discs 51 is arranged to decrease in the direction away from the 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 arrangement enables the covering disc 51 to roll against the soil, greatly reducing the resistance during covering, and the edge of the covering disc 51 can intrude into the soil surface, thereby ensuring that the amount of soil moved can form a covering soil layer meeting the thickness, providing a good wrapping effect for the root system, and also not causing a large labor burden to the transplanting operation. Preferably, both of the covering discs 51 are arranged in a manner that the axis direction is movable, so as to change the distance between the two covering discs 51. At the same time, the covering disc 51 is also connected with an elastic member, and the elastic force generated by the elastic member enables the distance between the two covering discs 51 to tend to decrease in the direction away from the breaking mechanism 3. During use, when encountering a stone or a larger seed hole structure, the resistance encountered by the covering disc 51 will overcome the elastic force of the elastic member, so that the covering disc 51 rotates around the rotating shaft, achieving a certain avoidance effect and further reducing the resistance during the transplanting operation.

[0073] For example, in the present embodiment, each covering disc 51 is arranged in a gap-fitting manner on a stud 52, and two limiting nuts 53 are arranged on each stud 52, and the covering disc 51 is arranged between the two limiting nuts 53. At the same time, the distance between the two limiting nuts 53 is greater than the thickness of the covering disc 51, so that the axis direction of the covering disc 51 is movable, thereby achieving a change in the distance between the two covering discs 51. Of course, in some embodiments, the axis direction of the covering disc 51 can also be achieved by arranging a rotating shaft or other rotating connection structure, which also belongs to the scope to be protected by the present application. Optionally, the covering disc 51 has a curved disc surface, and the distance between the two covering discs 51 decreases in the direction approaching the stud 52, thereby further optimizing the moving effect of 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 a conversion 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, and therefore the specific installation manner of the rotating shaft or other rotating connection structure is not limited in the present application, as long as the overall distance or the local distance between the two covering discs 51 can be changed when the covering disc 51 rotates around the rotating shaft. Similarly, the elastic member can also be arranged in various ways such as springs, elastic sheets, and therefore the specific structure and specific installation manner of the elastic member are not limited in the present application.

[0075] Continuing to refer to Figure 9As shown, in this embodiment, the compaction mechanism 6 includes two compaction rollers 61. The two compaction rollers 61 are set at a certain angle, so that the distance between the two compaction rollers 61 gradually decreases along the direction from top to bottom. This avoids the top leaves and other structures of individual seedlings, and also achieves a good compaction effect on the covering soil layer.

[0076] like Figure 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 it is convenient for a single person to lift and move the paper pot transplanter, further facilitating the application and promotion of the paper pot transplanter in mountainous and hilly areas.
