[0030] Embodiment: Refer to Figures 1-5 A floating plate device of a transplanter shown in the figure, which includes a main floating plate 1 and a mounting frame 5. A counterweight box 2 and a fixing frame 3 are provided on the main floating plate 1. A cross plate 4 is fixed at the front end of the main floating plate 1. Two groups of buffer components 6 are rotatably connected between the cross plate 4 and the mounting frame 5;
[0031] Two rack plates 8 are vertically slidably matched inside the mounting frame 5. A plurality of object detecting rods 10 are fixed between the two rack plates 8. The bottom of the object detecting rod 10 is provided with a bent portion. A rotating rod 17 is rotatably connected inside the mounting frame 5. Two gears 18 are fixedly sleeved on the circumferential surface of the rotating rod 17. The two gears 18 are respectively meshed with the two rack plates 8. One end of the rotating rod 17 penetrates through the mounting frame 5 and is fixed with a locking wheel 11. A plurality of locking grooves are formed on the circumferential surface of the locking wheel 11. A square column 13 is slidably matched on one side of the mounting frame 5. The square column 13 is a square column, and one end of the square column 13 is slidably matched in the locking groove.
[0032] The main floating plate 1 can be fixedly installed at the bottom of the transplanter through the fixing frame 3. A plurality of counterweight blocks are installed inside the counterweight box 2. By reducing the counterweight blocks, the buoyancy of the main floating plate 1 can be changed to meet the requirements of different paddy field operations;
[0033] During the rice transplanting operation, when there are hard foreign objects in the paddy field, the object detection rod 10 will be blocked by the foreign objects first. After the buffer assembly 6 is squeezed, it will contract and deform, playing a role in buffering the impact force received by the main floating plate 1, avoiding the deformation of the main floating plate 1 due to extrusion, and improving the anti-deformation ability of the main floating plate 1. By rotating the locking wheel 11, the rotating rod 17 can be driven to rotate, so that the gear 18 rotates and drives the rack plate 8 to move vertically, realizing the adjustment of the horizontal height of the object detection rod 10. By sliding one end of the square column 13 into the locking groove on the circumferential side of the locking wheel 11, the locking wheel 11 is locked and fixed, avoiding the rotation of the rotating rod 17 and improving the stability of the rack plate 8 during operation.
[0034] In order to improve the structural strength of the installation frame 5 and enable the installation frame 5 to move stably horizontally along a straight line, in this embodiment, a group of sliding rods 7 are fixed on one side of the installation frame 5, and the sliding rods 7 slide through the cross plate 4.
[0035] In order to enable the buffer assembly 6 to buffer the impact force received by the installation frame 5 and improve the stability of the rotating rod 17 during rotation, in this embodiment, the buffer assembly 6 includes two swing plates 61. A sliding plate 62 is slidably fitted between the two swing plates 61. The swing plate 61 is a hollow plate with one end open. A group of first springs 63 are fixed between one end of the sliding plate 62 and the inner groove wall of the swing plate 61. A reinforcing plate 19 is fixed inside the installation frame 5, and the rotating rod 17 slides through the reinforcing plate 19. The setting of the reinforcing plate 19 enables the rotating rod 17 to rotate stably inside the installation frame 5. Hinge seats 20 are fixed on both the cross plate 4 and one side of the installation frame 5, and the swing plate 61 is rotatably connected in the hinge seats 20. Through the hinge seats 20, the buffer assembly 6 can be rotatably connected between the cross plate 4 and the installation frame 5. When the object detection rod 10 is blocked by hard foreign objects, the installation frame 5 will move towards the cross plate 4 direction, and the two swing plates 61 will approach each other. When the sliding plate 62 slides inside the swing plate 61, the first spring 63 will be squeezed and contracted, realizing the buffering of the impact force received by the installation frame 5.
[0036] In order to enable the rack plate 8 to move vertically stably inside the installation frame 5, in this embodiment, a limiting plate 14 is fixed on one side of the rack plate 8, and a limiting groove 15 is formed on the inner side wall of the installation frame 5. The limiting plate 14 is slidably fitted in the limiting groove 15, which can limit the rack plate 8 inside the installation frame 5. A bottom plate 16 is fixed at the bottom end of the rack plate 8, and the bottom plate 16 plays a role in limiting, avoiding the rack plate 8 sliding out of the inside of the installation frame 5 during the upward sliding process. And a group of connecting plates 9 are fixed between the two rack plates 8, and the object detection rod 10 is fixed on the connecting plate 9. The setting of the connecting plate 9 improves the structural strength of the object detection rod 10, and several object detection rods 10 are arranged equidistantly along a straight line on the connecting plate 9.
[0037] To facilitate the control of one end of the square column 13 to penetrate deep into the locking groove so that the locking wheel 11 can be quickly locked, in this embodiment, a crank 12 is fixedly installed on the locking wheel 11, a side plate 21 is fixed on one side of the installation frame 5, an extension plate 22 is provided on the peripheral side of the square column 13, and one end of the square column 13 slidably penetrates through the side plate 21 and is fixed with a pull plate 25. A locking plate 24 is fixed at the other end of the square column 13, and a second spring 23 is fixed between the side plate 21 and the extension plate 22. By pulling the pull plate 25, the square column 13 can be driven to move horizontally, so that the locking plate 24 can slide out of the locking groove, and the second spring 23 deforms and contracts. At this time, the locking wheel 11 can be rotated. When the external force applied to the pull plate 25 is removed, under the action of the elastic restoring force of the second spring 23, the square column 13 will move in a straight line, so that the locking plate 24 automatically snaps into the locking groove of the locking wheel 11, locking the locking wheel 11 and preventing the locking wheel 11 from rotating.
[0038] The above description is only the preferred embodiment of the present application and the explanation of the applied technical principles. Those skilled in the art should understand that the scope of the utility model involved in the present application is not limited to the technical solution formed by the specific combination of the above technical features, but should also cover other technical solutions formed by any combination of the above technical features or their equivalent features without departing from the inventive concept of the utility model.
