DETAILED DESCRIPTION

[0027] The present invention is further described below in conjunction with specific embodiments. It should be understood that these embodiments are only used to illustrate the present invention and are not used to limit the scope of the present invention. In addition, it should be understood that after reading the content taught by the present invention, those skilled in the art can make various changes or modifications to the present invention, and these equivalent forms also fall within the scope defined by the present application.

[0028] like Figures 1 to 4 As shown, a device for automatically delivering and removing seedlings from a plug tray comprises a plug tray conveying mechanism, and a transmission mechanism and a seedling lifting mechanism installed on the plug tray conveying mechanism.

[0029] The hole tray conveying mechanism includes a frame 1, and a first rotating shaft 2 and a second rotating shaft 3 respectively connected to the frame 1 for rotation, the first rotating shaft 2 and the second rotating shaft 3 are connected for transmission via two transmission chains 4 arranged at intervals, a plurality of seedling transport rods 5 evenly arranged along the circumference of the transmission chains 4 are provided between the two transmission chains 4, both ends of the seedling transport rods 5 are respectively connected to the two transmission chains 4, the frame 1 is connected to a plurality of seedling guide rods 6, the seedling guide rods 6 are located between the two transmission chains 4 and are arranged on the outside of the plurality of seedling transport rods 5 at the first rotating shaft 2, and the shape of the seedling guide rods 6 is adapted to the trajectory of the transmission chain 4 at the first rotating shaft 2.

[0030] Specifically, the first rotating shaft 2 is respectively provided with the first sprocket 7 at both ends, and the second rotating shaft 3 is respectively provided with the second sprocket 8 at both ends, and the first sprocket 7 and the second sprocket 8 cooperate with the transmission chain 4. In the present embodiment, the hole tray conveying mechanism is used to convey the hole tray, realize the feeding of the hole tray, that is, send the seedling. The seedling transporting rod 5 is used to clamp the hole tray, and the hole tray is placed on the top of the hole tray conveying mechanism, so that the seedling transporting rod 5 is stuck in the interval between the two adjacent rows of holes at the bottom of the hole tray (the length direction of the seedling transporting rod 5 in the present embodiment is the row direction of the hole tray, and the conveying direction of the hole tray is the column direction of the hole tray), and now the transmission chain 4 rotates through the seedling transporting rod 5 to drive the hole tray to feed. The seedling guide rod 6 is used to guide the feeding of the hole tray, and ensures that the hole tray is fed along the track of the transmission chain 4 at the first rotating shaft 2, so as to avoid the hole tray from falling off. When the hole tray contacts with the seedling guide rod 6, the seedling guide rod 6 is located at the interval between the top row and the row of the hole tray, so as to avoid damaging the hole tray seedling.

[0031] The seedling pushing mechanism includes a plurality of seedling pushing rods 10 that reciprocate, and a third rotating shaft 11 for indirectly driving the seedling pushing rods 10 to reciprocate. The seedling pushing rods 10 are arranged between the two transmission chains 4 and face the seedling guide rods 6, and are used to be inserted into the drainage port of the plug tray to push the plug tray seedlings out of the plug tray. When the plug tray is fed to the seedling pushing mechanism, the seedling pushing rods 10 push the plug tray seedlings out of the plug tray to achieve seedling removal. The number of seedling pushing rods 10 is set according to the number of plug tray columns.

[0032] The transmission mechanism is arranged between the first rotating shaft 2 and the third rotating shaft 11, and is used to convert the continuous rotation of the third rotating shaft 11 into the intermittent rotation of the first rotating shaft 2. In this embodiment, the third rotating shaft 11 is a driving shaft, which can be driven by a power device such as a motor. The third rotating shaft 11 continuously rotates to make the top seedling rod 10 reciprocate and perform the top seedling action. The third rotating shaft 11 drives the first rotating shaft 2 to rotate intermittently through the transmission mechanism, and then makes the transmission chain 4 intermittently move, thereby realizing the intermittent feeding of the plug tray. When the plug tray feeds a certain angle, it will stagnate for a period of time. At this time, the plug tray seedlings are ejected from the plug tray by the top seedling rod 10. After the top seedling rod 10 leaves the plug tray, the plug tray performs the next step of feeding, and then the top seedlings are ejected until the entire plug tray seedlings are all taken out, thereby completing the entire seedling delivery operation process. After the plug tray that has completed the seedling removal is separated from the guide seedling rod 6, it can be removed from the bottom of the plug tray conveying mechanism. It should be noted that a receiving plate can be set at the seedling emergence position to receive the pushed out seedlings, and the receiving plate can be fixed on the frame 1.

[0033] The automatic seedling feeding and removing device for the plug tray of the present embodiment is driven by the plug tray conveying mechanism to intermittently feed the plug tray, and the seedling pushing mechanism pushes the plug tray seedlings out of the plug tray, which can replace manual seedling removal operations for the plug tray seedlings, thereby reducing labor costs, increasing efficiency, and avoiding the problem of manual seedling removal easily damaging the seedlings.

The plug tray transition plate 15 is arranged at one end of the frame 1, and is used to place the plug tray to be taken out of the seedlings. The partition 16 is located in the interval between the rows at the bottom of the plug tray. The partition 16 is used to preliminarily position the plug tray to be taken out of the seedlings. After completing the seedling taking operation of the previous plug tray, the plug tray on the plug tray transition plate 15 can be directly pulled onto the seedling transport rod 5.

[0037] In some embodiments, the seedling pushing mechanism further includes a bracket 17, a push rod 18, a seedling pushing rod seat 19, a reset spring 20 and a cam 21, the bracket 17 is relatively fixed to the frame 1, the push rod 18 is slidably connected to the bracket 17, the seedling pushing rod seat 19 is fixedly connected to one end of the push rod 18, a plurality of seedling pushing rods 10 are arranged on the seedling pushing rod seat 19 at equal intervals, the bracket 17 is rotatably connected to the third rotating shaft 11, the cam 21 is fixed on the third rotating shaft 11, and abuts against the other end of the push rod 18, and the reset spring 20 is arranged between the push rod 18 support and the bracket 17, and is used to reset the seedling pushing rod 10. The third rotating shaft 11 drives the cam 21 to rotate, and through the cam 21 and the reset spring 20, the push rod 18 and the seedling pushing rod 10 can reciprocate to push the seedlings out of the hole tray.

[0038] Specifically, the bracket 17 is fixedly connected to a connecting seat 22, the connecting seat 22 is rotatably connected to the first rotating shaft 2, the third rotating shaft 11 is rotatably connected to the frame 1, and the bracket 17 is fixed to the frame 1 through the above connection method.
