[0002] In the agricultural field, in order to improve the survival rate and yield of seedlings, it is usually necessary to use a seedling raising device for seedling raising. Currently, seedlings are mostly raised in planting pots, which are placed in the seedling raising room to ensure that the seedlings grow under suitable conditions. However, for those seedlings with a longer seedling raising cycle, as the seedlings grow, it is necessary to constantly replace the planting pots with larger sizes to adapt to the growth needs of the seedlings. In addition, in order to ensure that the seedlings can fully receive sunlight, it is also necessary to adjust the gap between the seedlings after each repotting. Repotting means that planting pots of different sizes need to be prepared, which increases the cultivation cost. Repotting and transplanting will also reduce the survival rate of the seedlings, and the steps of repotting and adjusting the seedling gap are performed separately, which makes the operation more cumbersome. In response to the above problems, the present invention proposes a transplant-free agricultural seedling raising device. Summary of the Invention

[0014] Compared with the prior art, the present invention provides a transplant-free agricultural seedling raising device with the following beneficial effects: 1. The present invention provides an adjustment device. During the seedling cultivation period, the adjustment device can be used to expand the seedling spacing and adjust the size of the planting trough.

When the planting trough surrounded by the enclosure is scaled with a certain scaling base point on plane Y, the soil and the seedlings in the soil can be pushed in the same direction as the moving direction of the seedling raising unit through the seedling transplanting structure, so that the position of the seedlings in the planting trough is always maintained in the center of the planting trough, providing sufficient space for the growth of the seedling roots. In addition, the soil-fixing end of the seedling transplanting structure can also reduce the loosening of the soil around the seedling roots, thereby improving the survival rate of the seedlings.

DETAILED DESCRIPTION
[0017] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0018] Example: See Figures 1 to 5 According to an embodiment of the present invention, a transplant-free agricultural seedling raising device is provided, which includes a plurality of seedling raising units 100 arranged in a plane Y at intervals, each seedling raising unit 100 having an adjustable planting trough 110, and the plurality of seedling raising units 100 are movable in plane Y; the transplant-free agricultural seedling raising device also includes an adjustment device capable of driving the plurality of seedling raising units 100 to synchronously adjust the size of the planting trough 110 as they move in plane Y. Specifically, in this embodiment, four seedling raising units 100 are provided, and the four seedling raising units 100 are arranged in a rectangular shape with a center point located on plane Y. The four seedling raising units 100 move in plane Y in a direction toward or away from the center point. It should be noted that when the plurality of seedling raising units 100 are moved in a direction away from each other in plane Y, the size of the planting trough 110 should gradually increase; and when the plurality of seedling raising units 100 are moved in a direction toward each other in plane Y, the size of the planting trough 110 should gradually decrease.
[0019] The transplant-free agricultural seedling raising device employing the above-described structure plants and cultivates seedlings by laying soil within a planting trough 110. During the seedling cultivation period, an adjustment device can be used to increase the spacing between seedlings while adjusting the size of the planting trough 110. Compared to existing technologies, this not only saves the cultivation costs associated with repotting and improves the survival rate of seedlings, but also allows for simultaneous adjustment of the planting trough 110 size and the seedling spacing, reducing operational difficulty. It should be noted that when the size of the planting trough 110 is adjusted, soil can be added or removed from the planting trough 110 to meet the soil requirements of the seedlings.
[0020] In some embodiments, each seedling unit 100 includes a base plate 120, a surrounding plate 130 and a reel 140. The base plate 120 has a support surface 121, and the support surface 121 is coplanar with plane Y. The surrounding plate 130 is elastic and forms a circular planting trough 110 on the support surface 121. The reel 140 is rotatably provided on the base plate 120; specifically, in this embodiment, the number of reels 140 is two, and the two ends of the surrounding plate 130 are respectively fixed to the two reels 140. By rotating the two reels 140 in opposite directions, the purpose of changing the size of the planting trough 110 surrounded by the surrounding plate 130 can be achieved; in other embodiments, the number of reels 140 can also be one, one end of the surrounding plate 130 is fixed to the base plate 120, and the other end is fixed to the reel 140. By rotating the reel 140, the size of the planting trough 110 surrounded by the surrounding plate 130 can also be changed.
[0021] In the above embodiment, when the size of the planting trough 110 is increased by rotating the reel 140, the gaps at both ends of the enclosure 130 will also increase, and the soil in the planting trough 110 may leak. In order to solve this problem, in some embodiments, each seedling unit 100 also includes a positioning shaft 150, and both ends of the enclosure 130 pass through between the two positioning shafts 150. The size of the enclosure 130 is scaled based on the positions of the two positioning shafts 150. The two positioning shafts 150 can limit the joints at both ends of the enclosure 130 to a reasonable gap to prevent the soil in the planting trough 110 from leaking out of the gaps at both ends of the enclosure 130. In order to reduce the friction during relative motion between the enclosure 130 and the positioning shaft 150, the positioning shaft 150 can be rotatably connected to the base plate 120 through a bearing.
[0022] In some embodiments, a retaining ring 122 is fixedly mounted on the support surface 121 of the base plate 120. The circle surrounding the retaining ring 122 is tangent to the scaling base point. The position of the retaining ring 122 near the scaling base point is open. The two ends of the retaining ring 122 are attached to the outer wall of the enclosure 130. The retaining ring 122 and the enclosure 130 together form a crescent-shaped closed area 160 on the support surface 121 of the base plate 120. The side of the enclosure 130 facing the closed area 160 is provided with a water outlet 131. The contact surface between the enclosure 130 and the base plate 120 and the contact surface between the retaining ring 122 and the enclosure 130 are both provided with a sealing structure (not shown). Specifically in this embodiment, the sealing structures between the contact surface between the enclosure 130 and the base plate 120 and the contact surface between the retaining ring 122 and the enclosure 130 can both be made of rubber. It is understandable that the closed area 160 is connected to the planting trough 110 through the water outlet 131, and a portion of the excess water in the planting trough 110 can flow into and be stored in the closed area 160 through the water outlet 131. This excess water can continue to provide the moisture required for the growth of the seedlings in the planting trough 110. In addition, since the planting trough 110 surrounded by the retaining ring 122 and the enclosure 130 is tangent to a certain scaling base point, the planting trough 110 will be scaled with the scaling base point as the reference point, and under the elastic action of the enclosure 130 and the action of the sealing structure, the four sides of the crescent-shaped closed area 160 will remain sealed during the scaling process of the planting trough 110, thereby ensuring that the closed area 160 always has the function of storing and supplying water.
[0023] In some embodiments, the adjustment device includes a support frame 200, a transmission component 210 and a driving component 220. The bottom plate 120 is slidably connected to the support frame 200 in plane Y. The driving component 220 is used to drive the bottom plate 120 to slide in plane Y. The support frame 200 and the reel 140 are connected by transmission component 210. Specifically, in this embodiment, the support frame 200 includes a top bracket 202, and the bottom plate 120 is slidably connected to the top bracket 202 through a slider 230. It can be understood that when the driving component 220 applies a driving force to the bottom plate 120, the driving force of the driving component 220 will be transmitted to the reel 140 through the transmission component 210, thereby driving the reel 140 to rotate, thereby achieving the purpose of driving multiple seedling units 100 to move in plane Y to synchronously adjust the size of the planting trough 110.
[0024] In some embodiments, the transmission component 210 is a first rack and pinion structure. More specifically, the first rack and pinion structure includes a first rack 2100 mounted on the top bracket 202 and a first gear 2101 coaxially fixed to the spool 140. The first gear 2101 and the first rack 2100 are meshed. It will be appreciated that when the spool 140 rotates, the first gear 2101 rotates along with the spool 140. The first gear 2101, through its engagement with the first rack 2100, drives the bottom plate 120 to slide within plane Y. In other embodiments, the transmission component 210 may also be a worm gear mechanism or a sprocket structure.
[0025] In some embodiments, the driving component 220 includes a sliding member 221, a connecting rod 222, and a driver 223. The sliding member 221 is slidably connected to the support frame 200, the connecting rod 222 is movably connected between the sliding member 221 and the bottom plate 120, and the driver 223 is used to drive the sliding member 221 to slide on the support frame 200. Specifically, in this embodiment, the support frame 200 also includes a main frame 201 perpendicular to the plane Y. The sliding member 221 is slidably sleeved on the outside of the main frame 201. The ends of the connecting rod 222 are respectively connected to the sliding member 221 and the slider 230 via a rotating shaft 224. The driver 223 can be specifically a cylinder, an electric push rod, or a hydraulic cylinder. It is understood that the sliding member 221 is driven to slide by the driver 223, and the sliding member 221 drives the bottom plate 120 to slide via the connecting rod 222, thereby changing the spacing between the multiple seedling raising units 100. At the same time, when the bottom plate 120 slides, it also drives the reel 140 to rotate via the first rack and pinion structure, thereby adjusting the size of the planting trough 110. Of course, there is no particular limitation on the specific structure of the driving component 220 as long as it can drive the bottom plate 120 to slide within the plane Y. In addition, in order to ensure that the support frame 200 can be stably placed on the ground, the support frame 200 can further include a bottom bracket 203. The structure of the bottom bracket 203 is substantially the same as that of the top bracket 202, both of which are cross-shaped.
[0026] In the above embodiment, when the planting trough 110 surrounded by the enclosure 130 is scaled with respect to a certain scaling base point on the plane Y, the position of the soil and seedlings in the planting trough 110 will not be able to remain in the middle position of the planting trough 110, which will be detrimental to the growth of the seedling root system. For this reason, in some embodiments, each seedling unit 100 further includes a seedling transplanting structure 170. The seedling transplanting structure 170 can move relative to the seedling unit 100 in the same direction as the movement direction of the seedling unit 100. The seedling transplanting structure 170 has a soil-fixing end, which includes a ring frame 171 and a plurality of plug-in parts 172. The plurality of plug-in parts 172 are arranged along the axial direction of the ring frame 171 and extend toward the axial direction of the ring frame 171. In a specific implementation, the soil-fixing end is placed in the planting trough 110, the ring frame 171 of the soil-fixing end is sleeved on the outside of the seedling, and the plug-in part 172 of the soil-fixing end is inserted into the soil in the planting trough 110. When the planting trough 110 surrounded by the enclosure 130 is scaled with a certain scaling base point on plane Y, the soil and the seedlings in the soil can be pushed in the same direction as the moving direction of the seedling unit 100 through the seedling transplanting structure 170, so that the position of the seedlings in the planting trough 110 is always maintained in the center of the planting trough 110, providing sufficient space for the growth of the seedling roots. In addition, the soil-fixing end of the seedling transplanting structure 170 can also reduce the loosening of the soil around the seedling roots, thereby improving the survival rate of the seedlings.
[0027] In some embodiments, the transplanting structure 170 further includes a driving end, which is connected to the reel 140 via a linkage component 173 so that the transplanting structure 170 and the seedling raising unit 100 move synchronously in the same direction. Specifically, in this embodiment, a plug-in sleeve 174 is fixed to the main frame, and the driving end of the transplanting structure 170 is movably connected to the plug-in sleeve 174. By providing the driving end of the transplanting structure 170, the three steps of moving the transplanting structure 170, moving the seedling raising unit 100, and adjusting the size of the planting trough 110 are synchronized, which facilitates the cultivation of seedlings.
[0028] In some embodiments, the linkage component 173 is a second rack and pinion structure. More specifically, the second rack and pinion structure includes a second rack 1730 provided on the driving end of the transplanting structure 170 and a second gear 1731 coaxially fixed to the reel 140, and the second gear 1731 and the second rack 1730 are engaged. It is understood that when the reel 140 rotates, the second gear 1731 rotates along with the reel 140, and the second gear 1731 drives the transplanting structure 170 to move in the same direction as the movement direction of the seedling raising unit 100 through engagement with the second rack 1730. In other embodiments, the linkage component 173 can also be a worm gear mechanism or a sprocket structure.
[0029] In some embodiments, in order to provide more sufficient light for the plants in the planting troughs 110 of multiple cultivation units, a fill light 300 fixed to the main frame is provided at the center point of plane Y. The fill light 300 can increase light for the easily obscured parts inside the seedlings.
[0030] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
