Description

Technical Field

[0001] This utility model relates to a seedling raising machine, and more particularly to a lane-changing robot for a seedling raising site. Background Technology

[0002] Seedling cultivation is the process of raising seedlings. It is a labor-intensive, time-consuming, and technically demanding task. Previously, seedling cultivation was done manually by experienced staff. This method of seedling cultivation is inefficient and cannot meet the needs of large-scale, high-volume seedling production.

[0003] Current seedling cultivation methods generally employ mechanized sowing in factories, followed by placing the sown seedling trays in greenhouses or outdoor cement fields / rice paddies for germination and seedling cultivation. The materials used to manufacture these seedling trays typically include polystyrene foam, polystyrene, polyvinyl chloride, and polypropylene, and manufacturing methods include blow molding and injection molding. Polystyrene is commonly used for seedling trays of vegetables and ornamental plants. For standardized management, a separate area can be set up as a seedling cultivation zone. This zone has multiple rows of evenly spaced longitudinal tracks. Multiple seedling trays are placed into the same tray, which is then moved by a transport trolley. The transport trolley has two rows of wheels, each row consisting of two front and two rear wheels. The trolley travels along the tracks, placing the seedling trays into the spaces between the tracks.

[0004] When the transport vehicle moves along the longitudinal track, it only achieves linear movement. If the transport vehicle needs to move from one row of longitudinal tracks to another row of longitudinal tracks, a lane-changing robot is needed to carry the transport vehicle on the transverse track and move it to the longitudinal track where the destination is located. Utility Model Content

[0005] This utility model provides a lane-changing robot for seedling nurseries, solving the problem of changing lanes for transport vehicles from one straight track to another. The technical solution is as follows:

[0006] A lane-changing robot for a seedling nursery includes a vehicle body. Fixed support frames for supporting transport vehicles or other robots are installed on the left and right sides of the vehicle body. Folding brackets are provided at the front and rear ends of the fixed support frames. When the lane-changing robot moves, the folding brackets flip upward at a certain angle. Wheels that move along a transverse track are provided under the vehicle body. At least one wheel is equipped with a drive motor, which is powered by a rechargeable battery inside the vehicle body.

[0007] The vehicle body includes two longitudinal supports and two transverse supports. The left and right sides of the transverse supports are fixedly connected to the two longitudinal supports. The longitudinal supports are used to fix the support frame. The front and rear sides of the longitudinal supports protrude.

[0008] The vehicle body is provided with positioning posts on the left and right sides, which are used to cooperate with the grooves of the charging pile.

[0009] The two longitudinal supports include a first longitudinal frame and a second longitudinal frame, and the two transverse supports include a first transverse frame and a second transverse frame; a first wheel and a second wheel are respectively installed on the left and right sides of the first transverse frame, and a third wheel and a fourth wheel are respectively installed on the left and right sides of the second transverse frame; a reinforcing support is provided between the first transverse frame and the second transverse frame, which are the first reinforcing frame and the second reinforcing frame.

[0010] The fixed support frame includes a first support frame installed on the left side of the vehicle body and a second support frame installed on the right side of the vehicle body; the folding brackets at the front and rear ends of the first support frame are respectively a first folding frame and a second folding frame; the folding brackets at the front and rear ends of the second support frame are respectively a third folding frame and a fourth folding frame; the first support frame and the second support frame are symmetrically arranged, the first folding frame and the second folding frame are symmetrically arranged, and the third folding frame and the fourth folding frame are symmetrically arranged.

[0011] The folding bracket includes a folding frame body, a first connecting rod, an electric telescopic rod, and a limiting connecting rod. The folding frame body is connected to one end of a fixed support frame via a pivot. The first connecting rod is fixed below one end of the fixed support frame near the folding frame body. A limiting connecting rod is fixed below the folding frame body. An electric telescopic rod is installed between the first connecting rod and the limiting connecting rod.

[0012] One end of the electric telescopic rod is connected to the first connecting rod via a first hinge, and the other end is connected to the limiting connecting rod via a second hinge.

[0013] The limiting connecting rod is designed in a triangular shape, with one side fixedly connected to the folding frame body, and the lower corner connected to the electric telescopic rod through a second hinge.

[0014] When the electric telescopic rod extends, the rod body at the front end of the electric telescopic rod enters the inner side of the limiting connecting rod until it touches the edge of the limiting connecting rod.

[0015] The lane-changing robot in the seedling nursery can move on a transverse track, assisting transport vehicles that can only move along a longitudinal track in changing lanes. The lane-changing robot can precisely move transport vehicles or other robots from the longitudinal track to different tracks, enabling robots to operate in multiple areas throughout the planting site, improving the equipment's working coverage and flexibility.

[0020] Figure 5 It is the aforementioned Figure 4 A magnified schematic diagram of part of the structure. Detailed Implementation

[0021] like Figure 1 and Figure 3 As shown, the lane-changing robot in the seedling site includes a vehicle body 1 and a fixed support frame 2 for supporting the transport vehicle or other robots. The fixed support frame 2 includes a first support frame 13 installed on the left side of the vehicle body 1 and a second support frame 16 installed on the right side of the vehicle body 1. Folding brackets are installed at both the front and rear ends of the support frame. When the transport vehicle or other robot drives onto the lane-changing robot and the lane-changing robot is ready to move, the folding brackets flip upward at a certain angle.

[0022] The vehicle body 1 includes two longitudinal supports and two transverse supports. The left and right sides of the transverse supports are fixedly connected to the two longitudinal supports, and the longitudinal supports are used to fix the support frame 2. The two longitudinal supports include a first longitudinal frame 3 and a second longitudinal frame 4, and the two transverse supports include a first transverse frame 5 and a second transverse frame 6. The front and rear sides of the longitudinal supports protrude, and the support frame 2 is also fixed to the protruding parts of the longitudinal supports by bolts, except for the middle part. A first wheel 7 and a second wheel 8 are respectively installed on the left and right sides of the first transverse frame 5, and a third wheel 9 and a fourth wheel 10 are respectively installed on the left and right sides of the second transverse frame 10. The vehicle body 1 moves along the transverse track by means of the four wheels. A reinforcing bracket, namely a first reinforcing bracket 19 and a second reinforcing bracket 20, is provided between the first transverse frame 5 and the second transverse frame 6 to strengthen the vehicle body 1.

[0023] The vehicle body 1 is equipped with a rechargeable battery 21, and at least one wheel is equipped with a drive motor (not shown in the figure) powered by the rechargeable battery 21. The drive motor drives the wheel to move, thereby moving the vehicle body along the transverse track. Figure 2As shown, positioning posts are provided on the left and right sides of the vehicle body 1. Nuts are screwed onto the bottom of the positioning posts. When the vehicle body 1 is without power and moves to the charging station, the positioning posts engage with the grooves provided on the charging station. When the positioning posts enter the grooves, the nuts press against the pressure sensors inside the grooves. The pressure sensors receive a signal, indicating that the vehicle body 1 has moved into position and that the charging interface of the vehicle body 1 is engaged with the charging socket of the charging station, enabling charging. In this utility model, a first positioning post 11 is provided on the left side of the second transverse frame 6, and a second positioning post 12 is provided on the right side. The third wheel 9 and the fourth wheel 10 are located between the first positioning post 11 and the second positioning post 12.

[0024] Combination Figure 4 As shown, the folding brackets at the front and rear ends of the first support frame 13 are the first folding frame 14 and the second folding frame 15, respectively; the folding brackets at the front and rear ends of the second support frame 16 are the third folding frame 17 and the fourth folding frame 18, respectively.

[0025] like Figure 5 As shown, taking one of the folding brackets as an example, the folding bracket includes a folding frame body 22, a first connecting rod 23, an electric telescopic rod 24, and a limiting connecting rod 25. The folding frame body 22 is connected to one end of a fixed support frame via a pivot 26. The first connecting rod 23 is fixed below the end of the fixed support frame near the folding frame body 22, and the limiting connecting rod 25 is fixed below the folding frame body 22. An electric telescopic rod 24 is installed between the first connecting rod 23 and the limiting connecting rod 25. One end of the electric telescopic rod 24 is connected to the first connecting rod 23 via a first hinge 27, and the other end is connected to the limiting connecting rod 25 via a second hinge 28. The electric telescopic rod 24 is equipped with a first motor 29 for telescopic drive. When the electric telescopic rod 24 extends, it pushes one end of the folding frame body 22 to rotate upward around the pivot 26 until the other end reaches a set angle. When the electric telescopic rod 24 retracts, it drives one end of the folding frame body 22 to rotate downward around the pivot 26 until it is horizontal.

[0026] Furthermore, to allow the folding frame body 22 to flip upwards until a set angle is reached, the limiting connecting rod 25 is designed in a triangular shape. One side (the top) is fixedly connected to the folding frame body 22, and the bottom corner is connected to the electric telescopic rod 24 via a second hinge 28. When the electric telescopic rod 24 extends, its body enters the inner side of the limiting connecting rod 25 until it touches the edge (top) of the limiting connecting rod 25, at which point it can no longer extend. This is the angle at which the folding frame body 22 flips upwards. By adjusting the shape of the limiting connecting rod 25, the flipping angle can be controlled.

[0027] This invention allows for movement on transverse tracks, enabling transport trolleys that can only move along longitudinal tracks to change lanes with the assistance of a lane-changing robot. The lane-changing robot can precisely move transport trolleys or other robots from longitudinal tracks to different tracks, allowing the robot to operate in multiple areas throughout the planting site, thus improving the equipment's working coverage and flexibility.
