[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0020] Please see Figure 1-6This utility model discloses a greenhouse device for leech farming, including a greenhouse body 1. The greenhouse body 1 has an overall U-shaped frame 3. The top inner wall of the frame 3 is connected to a crossbeam 5 by a reinforcing rod 4. The bottom of the crossbeam 5 located at both ends of the greenhouse body 1 is connected to a fixed rod 7 by a connecting rod 6. The top of the fixed rod 7 is provided with a movable groove 8. A movable block 10 is movably connected to the top of the fixed rod 7. A rack 11 is evenly provided on one side inner wall of the movable groove 8. The bottom of the movable block 10 is rotatably connected to a traveling gear 14 that meshes with the rack 11. A shade net 12 is connected to one side of the movable block 10. The side of the shade net 12 away from the movable block 10 is connected to the end of the fixed rod 7.
[0021] A transparent greenhouse film is installed on the outside of frame 3.
[0022] Adjacent skeletons 3 are connected by a connecting rod.
[0023] Specifically, one end of the main body 1 of the greenhouse is provided with an entrance / exit 2.
[0024] In this implementation plan, curtains are installed at the entrances and exits of the main body of the greenhouse 1 to facilitate the entry and exit of personnel.
[0025] Specifically, a drive motor 13 with an output shaft extending into the movable groove 8 is installed on the top of the movable block 10, and the walking gear 14 is fixedly sleeved on the output shaft of the drive motor 13.
[0026] In this embodiment, the drive motors 13 on the two movable blocks 10 operate synchronously. One end of the shade net 12 is fixedly connected to the end of the fixed rod 7, and the other end is connected to the movable block 10. When the drive motor 13 drives the walking gear 14 to rotate, the walking gear 14 can move along the rack 11 in the movable groove 8, causing the movable block 10 to move. Then the movable block 10 can pull the shade net 12 to unfold.
[0027] Specifically, the top of the fixed rod 7 is provided with a guide groove 9, and the bottom of the movable block 10 is equipped with a guide wheel 15 that is movably set in the guide groove 9.
[0028] In this embodiment, the cooperation between the guide wheel 15 and the guide groove 9 is to guide the movement of the traveling gear 14 and the moving block 10.
[0029] Specifically, the bottom end of the shade net 12 is evenly connected with guide blocks that are movably set in the guide groove 9.
[0030] In this embodiment, the shade net 12 is like a curtain with creases. Guide blocks are connected to the creases. When the traveling gear 14 moves toward the shade net 12, the guide wheel 15, which moves in the guide groove 9, can contact and abut against the guide block in the guide groove 9 so that the shade net 12 can be easily folded and stored.
[0031] Specifically, the two movable blocks 10 are connected by a connecting frame 17, and a reinforcing block 16 connected to the connecting rod 6 is fixedly connected to the top of the fixed rod 7.
[0032] In this embodiment, the reinforcing block 16 is triangular in shape.
[0033] In summary, the greenhouse device for leech farming uses a traveling gear 14 to move along the rack 11 in the movable groove 8, thereby moving the movable block 10. This allows the shade net 12 connected to the movable block 10 to be easily unfolded or retracted, and when the shade net 12 is unfolded, it can provide shade.
[0034] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
