DETAILED DESCRIPTION

[0028] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work fall within the protection scope of the present application.

[0029] Referring to Figures 1-8 The embodiments of the present application disclose a rape pot seedling transplanting machine, which comprises:

[0030] The power car head 1;

[0031] The seedling planting mechanism 3 comprises a support, a transmission shaft 27 and a first side plate 5, the support is connected with the power car head 1, the transmission shaft 27 is in transmission connection with the power car head 1, the transmission shaft 27 is in rotation connection with the support, and each end of the transmission shaft 27 is provided with a first side plate 5, a plurality of rotating shafts are arranged in parallel between the two first side plates 5, a plurality of duckbill planters 7 are arranged on each rotating shaft, and a switch assembly for controlling the opening and closing of the duckbill planter 7 is arranged on the duckbill planter 7;

[0032] The seedling sending mechanism 2 comprises a conveying belt connected with the power car head 1, and the seedling tray is placed on the conveying belt;

[0033] The seedling taking mechanism comprises a seedling taking support, a seedling taker 16, a central shaft and a rotating disc. The seedling taking support is connected with the power car head 1. The central shaft is fixedly connected with the seedling taking support. Two cams 13 are arranged on the central shaft. Two rotating discs are arranged at the two ends of the central shaft respectively. The rotating disc is rotationally connected with the central shaft. The rotating disc is drivingly connected with the power car head 1. A plurality of rotating frames 15 are arranged between the two rotating discs. A plurality of seedling clamps are arranged on each rotating frame 15. A slide rail is arranged on the sidewall of the two ends of the rotating frame 15. A first sliding block 11 is arranged on the slide rail. A lifting plate 12 is connected between the two first sliding blocks 11. A slide rod is arranged on the end of the lifting plate 12 close to the bottom plate of the rotating frame 15. The slide rod penetrates through the bottom plate and is slidingly connected with the bottom plate. A first spring 14 is arranged between the bottom plate and the lifting plate 12. The first spring 14 is arranged on the outer side of the slide rod. Two rotating plates are rotationally connected with the end of the slide rod away from the lifting plate 12. The seedling taker 16 comprises two clamping parts. The two clamping parts are rotationally connected with the rotating frame 15. A slide way is arranged on each clamping part. The end of the rotating plate away from the slide rod is arranged in the slide way. The seedling taker 16 is located at the output end of the conveying belt and above the duckbill planter 7.

[0034] In the process of transplanting the oilseed rape pot seedlings, the power car head 1 drives the conveying belt to move, so that the oilseed rape pot seedlings are transported to above the seedling taking mechanism. The power car head 1 drives one rotating disc to rotate. The rotating disc drives the other rotating disc to rotate through the rotating frame 15. When the rotating frame 15 rotates to the uppermost position, the protruding part of the cam 13 extrudes the lifting plate 12. At this time, the first sliding blocks 11 at the two ends of the lifting plate 12 slide on the slide rail to drive the lifting plate 12 to rise. The lifting plate 12 rises to compress the first spring 14. At the same time, the slide rod is pushed to rise. The slide rod drives the rotating plate to slide in the slide way, so as to push the two clamping parts to move away from each other, so that the seedling clamp is opened. At this time, the oilseed rape pot seedling is between the two clamping parts. The rotating disc continues to rotate. The rotating frame 15 moves away from the uppermost end. The cam 13 no longer extrudes the lifting plate 12. The lifting plate 12 returns to the initial position under the elastic force of the first spring 14. At the same time, the lifting plate 12 drives the slide rod to pull the clamping part to close, so as to realize the clamping of the pot seedling.

[0035] When the rotating frame 15 rotates to the lowermost end, the lifting plate 12 is extruded by the cam 13 again, so that the lifting plate 12 drives the slide rod to move to open the seedling clamp. At this time, the duckbill planter 7 moves to below the seedling clamp. The seedling clamp puts the pot seedling into the duckbill planter 7, so as to complete the transportation of the pot seedling.

[0036] The duckbill planter 7 rotates with the transmission shaft 27. When the duckbill planter 7 reaches the lowermost end, the duckbill planter 7 is inserted into the soil.

[0040] In the process of downward rotation of the spline shaft 22, the bidirectional screw rod 25 and the transmission shaft 27 are driven by the power car head 1, the rotation of the bidirectional screw rod 25 drives the two moving blocks 8 to move in different directions, and simultaneously drives the duckbill planters 7 at both ends to move in different directions, so that the pull rope 23 is straightened, and the distance between the duckbill planters 7 is adjusted.

[0041] In this process, the first side plate 5 drives the second side plate 4 to rotate, and at the same time, under the action of the interaction force, the second side plate 4 drives the first side plate 5 to rotate, so as to ensure that the duckbill planter 7 is always downward during the rotation of the key shaft 22, thereby avoiding that the pot body seedling is thrown out of the duckbill planter 7.
