[0041] See Figures 1 to 4 This embodiment provides a tidal device for a circulating seedling bed. The circulating seedling bed 100 includes a conveyor chain 110. The conveyor chain 110 forms a seedling tray hanging basket conveying track. The seedling tray hanging basket conveying track includes a curved track 111 and a straight track 112. The straight track 112 forms a tidal immersion area 113 at the front end position along the conveying direction of the conveyor chain 110. The tidal device of the circulating seedling bed is located in the tidal immersion area 113. The tidal device of the circulating seedling bed includes a water collection tank 1 and a reflux area 2.

[0042] The water collecting tank 1 is arranged below the conveying chain 110 so as to be immersed in the seedling tray hanging basket 120 which moves along the curved track 111 to the straight track 112 .

[0043] The reflow zone 2 is located behind the water collecting tank 1 along the conveying direction of the conveyor chain 110 and is used to guide the liquid dripping from the seedling tray hanging basket 120 into the water collecting tank 1.

[0044] The straight track 112 is inclined upward along the conveying direction of the conveyor chain 110 .

[0045] The conveyor chain 110 can be a chain structure, and the conveyor chain 110 is used to drive the seedling tray hanging basket 120 to circulate along the curved track 111 and the straight track 112. Along the movement direction of the seedling tray hanging basket 120, the intersection of the curved track 111 and the straight track 112 is a tidal immersion area 113, see Figure 2 , the movement direction of the conveying chain 110 in the straight track 112 is from left to right, and the left end of the straight track 112 is divided into a tidal immersion area 113. The water collection tank 1 can be filled with water. When the conveying chain 110 drives the seedling tray hanging basket 120 to move from the curved track 111 to the straight track 112, the seedling tray hanging basket 120 can be partially immersed in the water of the water collection tank 1. Since the straight track 112 is inclined upward, the seedling tray hanging basket 120 continues to move along the straight track. The basket 120 can gradually move away from the sump 1 and move to above the recirculation area 2. During the movement above the recirculation area 2, excess water in the seedling tray hanging basket 120 can drip onto the recirculation area 2 and flow into the sump 1 through the recirculation area 2. When the seedling tray hanging basket 120 continues to move away from above the recirculation area 2, the excess water in the seedling tray hanging basket 120 is basically filtered out, thereby avoiding the situation where excess water in the tray drips layer by layer along the bottom of the seedling tray hanging basket 120 during the rising process of the seedling tray hanging basket 120.

[0046] The tidal device of the circulating seedling bed provided in this embodiment provides a water collection trough 1 and a recirculation area 2 arranged in front and back at the end of the straight track 112 of the circulating seedling bed 100, so that the seedling tray hanging basket 120 moving on the straight track 112 can first be immersed in the water in the water collection trough 1 and then the excess water can be dripped into the recirculation area 2 and flowed back to the water collection trough 1, thereby solving the problem in the background technology that the excess liquid in the seedling hanging basket of the traditional circulating seedling bed will drip down layer by layer along the bottom of the seedling hanging basket.

[0047] Further, see Figure 2 The reflow zone 2 includes a guide plate 21, one end of the guide plate 21 is connected to the side wall of the water collection tank 1, and the other end is inclined upward along the conveying direction of the conveyor chain 110, so that excess water on the seedling tray hanging basket 120 can flow back to the water collection tank 1 smoothly when it drips onto the guide plate 21.

[0048] Furthermore, along the conveying direction of the conveyor chain 110, the length of the recirculation zone 2 is 1.5 to 3 times, preferably 2 times, the length of the water collection tank 1, to ensure that the excess water in the seedling tray hanging basket 120 can be fully drained during the transportation process above the recirculation zone 2.

[0049] Furthermore, the guide plate 21 is parallel to the straight track 112, so that excess water of the seedling tray hanging basket 120 can drip onto the guide plate 21 during the movement.

[0050] Further, see Figure 1 and Figure 2, and also includes a spraying mechanism 3, which is located above the water collecting tank 1 and is used to spray liquid, such as water or liquid medicine, on the seedling tray hanging basket 120 above the water collecting tank 1, and allow excess water or liquid medicine after spraying to flow directly into the water collecting tank 1.

[0051] Further, see Figure 1 , and also includes a depth adjustment mechanism 4, which is connected to the part of the conveying chain 110 relative to the tidal immersion area 113. The immersion depth of the seedling tray hanging basket 120 in the water collection tank 1 can be adjusted by adjusting the part of the conveying chain 110 relative to the tidal immersion area 113.

[0052] Further, see Figure 1 and Figure 2 The depth adjustment mechanism 4 includes a lifting wheel 41 and a tensioning wheel 42.

[0053] The lifting wheel 41 is connected to the portion of the conveying chain 110 relative to the tidal submerged area 113 through a transmission mechanism, and the lifting wheel 41 is connected to the circulating seedling raising bed 100 through a lifting structure 43 .

[0054] The tensioning wheel 42 is connected to the portion of the conveying chain 110 relative to the curved track 111 , and the tensioning wheel 42 is connected to the circulating seedling bed 100 through the tensioning structure 44 .

[0055] Among them, the conveying chain 110 can be a chain, the lifting wheel 41 and the tensioning wheel 42 can be sprockets, and the lifting structure 43 and the tensioning structure 44 can be conventional air pressure or hydraulic rod drive structures to drive the lifting wheel 41 and the tensioning wheel 42 to rise and fall. In the process of adjusting the immersion depth of the seedling tray hanging basket 120 in the water collection tank 1, the lifting structure 43 drives the lifting wheel 41 to descend, which can drive the part of the conveying chain 110 engaged with it to descend, so that the seedling tray hanging basket 120 in the tidal immersion area 113 can be lowered, and at the same time, the tensioning structure 44 can drive the tensioning wheel 42 to rise, thereby ensuring that the conveying chain 110 is not loose; if the seedling tray hanging basket 120 in the tidal immersion area 113 needs to be raised, the lifting wheel 41 can be driven to rise by the lifting structure 43, and at the same time, the tensioning structure 44 can drive the tensioning wheel 42 to fall.

[0056] Furthermore, the immersion depth of the seedling tray hanging basket 120 in the water collection tank 1 is two-thirds of the height of the seedling tray hanging basket 120 to ensure that the matrix in the seedling tray hanging basket 120 fully obtains water.

[0057] Further, see Figure 3 , in the examples provided in this embodiment:

[0058] A drain pipe 11 is provided on the side of the water collecting tank 1 to discharge excess water in the water collecting tank 1. The drain pipe 11 can be connected to an external container or directly connected to a ditch through a pipe; the side of the water collecting tank 1 can also be connected to a water inlet pipe, and water can be added to the water collecting tank 1 through the water inlet pipe.

[0059] The height of the seedling tray hanging basket 120 is 10-100 mm, preferably 30 mm.

[0060] Furthermore, a silt removal mechanism 12 is provided at the bottom of the water collection tank 1 to facilitate cleaning of the silt at the bottom of the water collection tank 1 .

[0061] See Figure 3 The silt removal mechanism 12 includes a sand filter net 121 laid at the bottom of the water collection tank 1. When the sediment at the bottom of the water collection tank 1 needs to be cleaned, the sand filter net 121 can be taken out from the bottom of the water collection tank 1 and replaced with a new sand filter net 121 at the bottom of the water collection tank 1.

[0062] See Figure 4 In another embodiment provided in this embodiment, the silt removal mechanism 12 may further include a sand scraper 122 slidably arranged at the bottom of the water collection tank 1. The sand scraper 122 is connected to a control rod 123 extending to the outside of the water collection tank 1. By manually pulling or pulling the control rod 123 by a linear motor, the sand scraper 122 can be pulled to slide along the bottom of the water collection tank 1, thereby gathering the mud and sand at the bottom of the water collection tank 1 on one side for easy cleaning.

[0063] Working principle:

[0064] The conveyor chain 110 can be a chain structure, and is used to drive the seedling tray hanging basket 120 to circulate along the curved track 111 and the straight track 112. Along the movement direction of the seedling tray hanging basket 120, the intersection of the curved track 111 and the straight track 112 is a tidal immersion area 113, see Figure 2 , the movement direction of the conveying chain 110 in the straight track 112 is from left to right, and the left end of the straight track 112 is divided into a tidal immersion area 113. The water collection tank 1 can be filled with water. When the conveying chain 110 drives the seedling tray hanging basket 120 to move from the curved track 111 to the straight track 112, the seedling tray hanging basket 120 can be partially immersed in the water of the water collection tank 1. Since the straight track 112 is inclined upward, the seedling tray hanging basket 120 continues to move along the straight track. The basket 120 can gradually move away from the sump 1 and move to above the recirculation area 2. During the movement above the recirculation area 2, excess water in the seedling tray hanging basket 120 can drip onto the recirculation area 2 and flow into the sump 1 through the recirculation area 2. When the seedling tray hanging basket 120 continues to move away from above the recirculation area 2, the excess water in the seedling tray hanging basket 120 is basically filtered out, thereby avoiding the situation where excess water in the tray drips layer by layer along the bottom of the seedling tray hanging basket 120 during the rising process of the seedling tray hanging basket 120.
