[0002] In the process of watermelon transplanting, in order to prevent flooding and retain moisture, the land for transplanting seedlings needs to be covered with film; this makes watermelon seedlings unsuitable for planting by sowing, because when the seeds germinate and emerge from the soil, the film will cover the seedlings. Therefore, watermelon transplanting is mainly divided into two types: transplanting first and then covering with film and covering with film first and then transplanting; among them, transplanting first and then covering with film, that is, after the watermelon seedlings are transplanted, the ground film is spread on the ground, and an opening is made on the ground film above the watermelon seedlings so that the seedlings are exposed from the opening of the ground film. This method is easy to damage the leaves of the seedlings and has a great impact on the survival rate of the watermelon seedlings; covering with film first and then transplanting, that is, first covering the ground with film and then transplanting the seedlings, which will not damage the leaves of the seedlings, and the survival rate of the seedlings is also high, but because the film covering only covers its edges with soil, when transplanting the watermelon seedlings, it is necessary to drill through the film from top to bottom and then realize drilling and transplanting, the film is easy to shift, and the coverage effect on the land is poor.

[0018] 1. The present invention provides an automatic planting device for transplanting watermelon seedlings. Before transplanting the watermelon seedlings, the watermelon seedlings are cultivated using a seedling tray. When the watermelon seedlings grow to a size suitable for transplanting, the entire seedling tray is placed in a seedling box on a frame. When transplanting the watermelon seedlings, the power platform is used to drive the entire planting device to operate on the ridged land covered with film. The operator sits on a seat and only needs to take the seedling tray out of the seedling box and place it on a conveyor belt group, and the planting device can be used to transplant the watermelon seedlings. The power platform transmits power to the transplanting component via the first transmission component, transmits power to the seedling guide component via the first transmission component and the second transmission component, and transmits power to the seedling guide component via the first transmission component, the second transmission component and the third transmission component.

[0019] 2. The automatic planting device for transplanting watermelon seedlings provided by the present invention has a seedling-pushing transmission cam connected to a seedling-pushing transmission shaft. During the rotation of the seedling-pushing transmission cam, the seedling-pushing main shaft arranged in cooperation with the seedling-pushing main shaft is periodically lifted upward. The seedling-pushing rod connected to the seedling-pushing main shaft passes through the water leakage hole of the seedling tray to push out the watermelon seedlings inside the main shaft. After one seedling-pushing is completed, the seedling-pushing main shaft is restored to the original device under the action of a second spring and is retracted from the water leakage hole of the seedling tray to wait for a second operation. The device has a simple structure and reliable functions.

[0020] 3. The automatic planting equipment for transplanting watermelon seedlings provided by the present invention has a seedling guide control cam with a slide groove connected to the seedling guide transmission shaft, and is connected to the seedling guide tube through a slider. When the seedling guide transmission shaft rotates with the second transmission component, the seedling guide control cam rotates accordingly, and the seedling guide tube is clamped between the guide slide bars and can only slide along its axial direction, so that the two middle seedling guide tubes move toward each other (away from each other or closer to each other) along the axial direction of the guide slide bars, and the remaining seedling guide tubes are rotatably connected through the first connecting rod, the second connecting rod, the third connecting rod and the fourth connecting rod that constitute a parallelogram truss, so that the remaining seedling guide tubes also move toward each other (away from each other or closer to each other), that is, the multiple seedling guide tubes can be brought closer to each other or dispersed away under the action of the seedling guide control cam, the slider, the parallelogram truss structure (the first connecting rod, the second connecting rod, the third connecting rod and the fourth connecting rod) and the guide slide bar. When all the seedling guide tubes are folded up, the seedling guide tubes are correspondingly arranged under the seedling tray so as to catch the watermelon seedlings pushed out from the seedling tray. When all the seedling guide tubes are far away and dispersed, the seedlings inside them are transported to the position of the corresponding transplanting assembly. In the process of transporting the seedlings, the bottom plate is slidably connected with the control slide bar, the bottom plate is in a horizontal state to close the outlet end of the seedling guide tube. After reaching the specified position, the bottom plate is separated from the control slide bar, and the bottom plate is in a vertical state under the action of the torsion spring, so that the outlet end of the seedling guide tube is opened, so that the seedlings inside can fall out smoothly; when the seedling guide tube is folded up again, the bottom plate will be in a horizontal state again under the action of the control slide bar to overcome the force of the torsion spring, close the outlet end of the seedling guide tube, and wait for the second operation; the guide tube is set to a wedge shape with a larger top and a smaller bottom, so that the seedlings can enter the seedling guide tube, and the seedlings inside it are straightened, so that the self-reliance of the seedlings to be transplanted is good and the survival rate of transplanting is high;

[0021] 4. The present invention provides an automatic planting device for transplanting watermelon seedlings. The transplanting component adopts a duckbill transplanting component. The transplanting main shaft is connected to the transplanting crankshaft through a driving connecting rod, and is also slidably connected to a limiting groove body, so that when the transplanting crankshaft rotates with the first transmission component, the duckbill component moves up and down to be used for transplanting the seedlings inside it; wherein, when the duckbill component moves downward and does not contact the duckbill control board, the first duckbill and the second duckbill move closer to each other under the action of the first spring, so that the watermelon seedlings are always on the inside of the duckbill component, and the tips of the lower sides of the first duckbill and the second duckbill pierce the film and are inserted into the soil, and are inserted into the soil to the finger After the depth is determined, the duckbill control shafts connected to the first duckbill and the second duckbill abut against the triangular duckbill control plate, so that the first duckbill and the second duckbill move away from each other under the action of the first spring, so as to open the duckbill so that the seedlings fall out of the duckbill assembly, and at the same time the duckbill moves upward, the first duckbill and the second duckbill move closer to each other under the action of the first spring, and the soil around the seedlings completes the covering of the seedlings under the action of the self-restoring force; after the transplanting of one row of seedlings is completed, the duckbill assembly moves upward under the action of the driving connecting rod to wait for the secondary operation; the structure can directly transplant watermelon seedlings on the film-covered land, and the transplanting effect is good and the efficiency is high;

[0022] 5. The automatic planting device for transplanting watermelon seedlings provided by the present invention sets twelve watermelon seedlings in one row of a seedling tray, sets twelve seedling-lifting rods, seedling-guiding tubes, duckbill assemblies and duckbill control panels, and can complete the transplanting of 12 rows in one action; and the power platform sets multiple operating gears, and different operating gears can adjust the spacing of each row of watermelon seedlings, and the adjustment is convenient; the power platform selects a tractor, which has good passability and is suitable for operation / use in watermelon fields; the passability of the entire planting equipment and / or the height of the frame from the ground are adjusted by the height adjustment assembly, which can not only ensure the passability of the entire equipment, but also adjust the transplanting depth of the watermelon seedlings to adapt to different land properties; the transmission assembly selects a chain transmission assembly, which has reliable transmission and accurate transmission ratio, and is convenient for controlling the operating parameters of each assembly;

[0023] 6. The present invention provides an automatic planting device for transplanting watermelon seedlings. A protective plate is arranged between a seat and a conveyor belt group to prevent soil in the seedling tray from falling onto the operator. A horizontal placement portion and an inclined seedling emergence portion are arranged on the conveyor belt group. The horizontal placement portion is convenient for workers to place the seedling tray, and the inclined seedling emergence portion is convenient for the seedlings to be pushed out. A baffle is arranged on the base frame so that the pushed-out seedlings are "straightened" under the action of the baffle, so that they fall vertically downward under the action of soil at the roots, further improving the correctness of transplanting and ensuring the survivability of transplanting. Moreover, the baffle can also protect the seedling guide component and the transplanting component to prevent external soil / rainwater / leaves from falling into the component and affecting the functionality of each component.
