DETAILED DESCRIPTION

[0033] The following will be described in detail with reference to the accompanying drawings. Figures 1-6 The application is further described in detail.

[0034] The embodiment of the application discloses a liquid supplementing device in a seedling transplanting process.

[0035] Reference Figure 1 A liquid supplementing device in a seedling transplanting process comprises two slide rails 1 arranged in parallel and a plug tray 2 arranged on the slide rails 1, a plurality of planting cavities are arranged in the plug tray 2, and a plurality of seedlings 21 are planted in the planting cavities in an array. The slide rail 1 is provided with a stacking tray feeding mechanism 3 at one end away from the advancing direction and a draining rack 4 at the end of the advancing direction. The former is used for continuously feeding the plug tray 2 to the slide rail 1, so as to ensure efficient and continuous feeding and moving of the plug tray 2, and the latter is used for draining nutrient solution on the plug tray 2, so as to avoid the seedlings 21 from being excessively soaked in the nutrient solution and dying.

[0036] Reference Figure 1 The slide rail 1 comprises a movable part 11 that can move up and down and two fixed parts 12 located at two ends of the movable part 11 in the horizontal direction, and the two fixed parts 12 both have mechanical structures capable of driving the plug tray 2 to move horizontally. When the slide rail 1 is in an initial state, the movable part 11 and the two fixed parts 12 are located on the same horizontal plane. The mechanical structures mentioned herein include but are not limited to structures such as a conveying belt, a transmission chain and a supporting plate.

[0037] Reference Figure 1 and Figure 2 The movable part 11 is arranged on a stand 6 in the vertical direction, and the stand 6 is integrally connected with an immersion barrel 5 containing nutrient solution on one side. The movable part 11 is arranged on the stand 6 in the vertical direction, and the stand 6 is provided with a displacement mechanism 7 for driving the movable part 11 to move up and down, so that the plug tray 2 can be fully soaked in the nutrient solution, and the nutrient supplement of the seedlings 21 is ensured.

[0038] It should be noted that the nutrient solution in the present application can not only provide nutrition for the seedlings 21, but also has a screening effect, which can be used to help the seedling tray cultivation personnel remove weak seedlings, small seedlings and mixed plants during the seedling 21 period, and improve the yield and output rate of corn.

[0039] With reference to Figure 2 Further, the top end of the stand 6 is slidingly provided with a telescopic baffle 61 for abutting the plug tray 2 moving to the active part 11 on the fixed part 12 to move to the designated position. The telescopic baffle 61 is connected with a driving member 62 to drive the telescopic baffle 61 to move up and down. When the plug tray 2 moves along the slide rail 1, the bottom of the telescopic baffle 61 is below the slide rail 1, at this time it will not affect the movement of the plug tray 2. When the plug tray 2 needs to be immersed, the telescopic baffle 61 is driven to rise by the driving member 62 to limit the plug tray 2.

[0040] Preferably, the stand 6 and the telescopic baffle 61 are provided with a force relieving pad 611 on the side close to the liquid immersion barrel 5, which is used to prevent the plug tray 2 from colliding with the telescopic baffle 61 and the stand 6, thereby causing damage to the structure of the plug tray 2, and improving the safety of the device operation.

[0041] With reference to Figure 2 Specifically, the displacement mechanism 7 includes two guide screws 71 symmetrically arranged to rotate on the side of the stand 6 away from the liquid immersion barrel 5, a driving motor 72 fixedly arranged on the stand 6, and two supporting rods 73 one end of which is respectively threadedly connected with the two guide screws 71. The ends of the two supporting rods 73 away from the guide screws 71 are abutted to the bottom side of the active part 11 and are slidingly arranged on the stand 6 in the transverse direction, which is used to support the active part 11 to move up and down. The driving motor 72 is drivingly connected with the two guide screws 71, and drives the two guide screws 71 to rotate synchronously to ensure that the two supporting rods 73 are always on the same horizontal plane.

[0042] With reference to Figure 2 and Figure 3 The ends of the two supporting rods 73 away from the guide screws 71 are slidingly arranged along the axis of the limiting slide rod 74, and the end of the limiting slide rod 74 away from the supporting rod 73 is fixedly connected with a limiting baffle 75 on the side close to the fixed part 12. The limiting baffle 75 is arranged obliquely with the limiting slide rod 74, and a tension spring 76 is sleeved on the limiting slide rod 74. The two ends of the tension spring 76 are connected with the limiting baffle 75 and the supporting rod 73 respectively, so that when the supporting rod 73 supports the active part 11 to move up and down, the limiting baffle 75 can abut the side of the plug tray 2, thereby ensuring that the plug tray 2 will not be separated from the active part 11 to cause an accident.

[0043] With reference to Figure 4, the draining rack 4 comprises a bottom plate 41 and two side plates 42 arranged on both sides of the bottom plate 41 and serving as position limiters. The bottom plate 41 comprises two flat areas 411 arranged on both sides and connected with the two side plates 42, two bending areas 412 connected with the two flat areas 411 respectively, and an arc area 413 integrally connected with the two bending areas 412 on the side close to each other.

[0044] The bending areas 412 are bent towards the ground, so that the nutrient solution dripping from the plug tray 2 can flow along the bending areas 412 to the arc area 413 for collection. In addition, the two ends of the arc area 413 along the axis of the draining rack 4 are located at different heights, so that the nutrient solution can be collected more conveniently, and the recycling of the nutrient solution is facilitated while maintaining the overall cleanliness of the device.

[0045] Referring to Figure 1 and Figure 4 , further, the end of the arc area 413 close to the ground in the vertical direction is close to the fixed part 12 and is connected with a recovery pipeline 43. The other end of the recovery pipeline 43 is in communication with the liquid immersion barrel 5, so as to ensure that the nutrient solution can be fully utilized and avoid resource waste.

[0046] Referring to Figure 5 , specifically, the stacked plug tray loading mechanism 3 comprises a loading transmission platform 31 placed on the ground and a lifting frame 32 arranged on the loading transmission platform 31 close to one end of the fixed part 12. The lifting frame 32 is symmetrically provided with two circulating transmission belts 321, and a plurality of lifting plates 322 are symmetrically and spacedly connected on the two circulating transmission belts 321. The two lifting plates 322 on the same horizontal plane jointly lift the plug tray 2 to make it rise.

[0047] The top end of the lifting frame 32 is provided with a horizontal transmission belt 323 coplanar with the slide rail 1, and a push piece 324 for pushing the plug tray 2 and pushing it onto the slide rail 1 is connected on the horizontal transmission belt 323.

[0048] Through the above structure, the device can continuously move the plug tray 2 to the draining rack 4, realize automatic liquid immersion operation during the transplanting process, and greatly save labor consumption.

[0049] Referring to Figure 1 and Figure 6 , the liquid immersion barrel 5 is provided with an auxiliary push rod 8 away from the stand 6, and the auxiliary push rod 8 is connected with a directional cylinder 81 for pushing the plug tray 2 on the movable part 11 to the other fixed part 12, so as to ensure that the plug tray 2 immersed in the nutrient solution can be transported to the draining rack 4.

[0050] Specifically, the auxiliary push rod 8 is flush with the lower end of the fixed part 12 on the side away from the liquid immersion barrel 5, so as to avoid affecting the movement of the plug tray 2 conveyed from the fixed part 12 to the movable part 11. The auxiliary push rod 8 is provided with an elastic pin 82 at the end away from the directional air cylinder 81, and the top end of the elastic pin 82 penetrates the slide rail 1 in the vertical direction when the elastic pin 82 is not compressed.

[0051] When the plug tray 2 moves from one fixed part 12 to the movable part 11, the elastic pin 82 is compressed and shrinks, and does not affect the movement of the plug tray 2. When the plug tray 2 moves from the movable part 11 to another fixed part 12, the elastic pin 82 is pushed out and pushes the plug tray 2 to move.

[0052] The implementation principle of the seedling transplanting process liquid supplementing device is as follows:

[0053] The plug tray 2 is first placed on the feeding transmission platform 31 by workers or a flow line, and is moved to the lifting position of the lifting frame 32 with the operation of the feeding transmission platform 31. Then, the lifting plates 322 located on the two circulating transmission belts 321 are jointly lifted to lift the plug tray 2 under the drive of the two circulating transmission belts 321. When the plug tray 2 is lifted to the top end of the lifting frame 32, the plug tray 2 is sent to the fixed part 12 by the paddle 324 under the drive of the horizontal transmission belt 323.

[0054] When the plug tray 2 is conveyed to the movable part 11 after passing through the first fixed part 12, the telescopic baffle 61 at the top end of the stand 6 limits the plug tray 2, and the plug tray 2 is driven by the supporting rod 73 to enter the liquid immersion barrel 5 to be soaked in nutrient solution. Then, the soaked plug tray 2 is lifted and pushed to the second fixed part 12 by the auxiliary push rod 8 to continue moving in the horizontal direction.

[0055] The second fixed part 12 continuously operates to convey the plug tray 2 to the draining frame 4. At this time, excessive nutrient solution in the plug tray 2 falls under the action of gravity and is collected in the arc-shaped area 413, and finally returns to the liquid immersion barrel 5 through the recovery pipeline 43, so as to realize the recycling of resources.

[0056] The above are preferred embodiments of the present application, and are not intended to limit the protection scope of the present application, so that: any equivalent changes made on the basis of the structure, shape, principle of the present application should be covered within the protection scope of the present application.
