Technical Field

[0001] The utility model relates to a hanging device, in particular to a yellow belt quick hanging device for a multi-span greenhouse, belonging to the technical field of greenhouse pest control. Background Art

[0002] Pest and disease control is a crucial component of greenhouse production. It's a long-term process, spanning from greenhouse preparation to completion. It's a multifaceted process, encompassing everything from soil and water sources to greenhouse interiors, from tool disinfection to skylight insect screens. All of this is designed to reduce the likelihood of pests and diseases, minimize chemical pesticide use, and ultimately produce healthy and safe agricultural products.

[0003] Yellow tape, also known as yellow-blue sticky insect tape, is a single-sided glue-coated strip structure, mainly used for pest control in multi-span greenhouses. It uses specific colors (yellow / blue) and insect pheromones in combination with hanging to lure and kill pests such as aphids, whiteflies, tobacco whiteflies, planthoppers, leafhoppers, leafminers, etc. These pests have a strong tendency to yellow, so they will be attracted to the yellow tape and stick to it, thereby achieving the purpose of pest control.

[0053] The top of the reel-and-unreel rack 401 is opened by rotating the cover plate 403 so that the take-up roller 405 and the yellow tape roll 404 can be installed into the interior of the reel-and-unreel rack 401 and sleeved on the two connecting shafts 410; the output shaft of the reduction motor 406 drives the first gear 407 to rotate, and the rotating first gear 407 drives the two connecting shafts 410 to rotate using the second gear 408 and the third gear 409, and one rotating connecting shaft 410 drives the yellow tape roll 404 to release the yellow tape, and the other reversely rotating connecting shaft 410 drives the take-up roller 405 to rewind and recycle the used yellow tape.

[0054] In one embodiment, four slide grooves 52 are formed on adjacent sides of the inner side walls of the four expansion ears 304. The inner side walls of the four slide grooves 52 are slidably connected to two slides 51. Four springs 53 are fixedly connected to one side of the inner side walls of the four expansion ears 304. One end of the four springs 53 is fixedly connected to one side of the two slides 51. A pressure roller 54 is rotatably connected to one side of the inner side walls of the two slides 51. The outer side walls of the pressure roller 54 are covered with an anti-sticking film 55. A handle 56 is fixedly connected to the non-adjacent sides of the two slides 51.

[0055] By moving the handle 56 and utilizing the slide 51 to drive the spring 53 and the pressure roller 54 to move, the moving spring 53 is compressed, and the moving pressure roller 54 drives the anti-sticking film 55 to separate from one side of the drum 303, and the sliding groove 52 is provided to guide the moving slide 51.

[0056] When the present invention is in operation: the cover plate 403 is rotated by twisting the knob 57, and the cover plate 403 is rotated to open the top of the retracting rack 401 so that the take-up roller 405 and the yellow tape roll 404 can be installed into the interior of the retracting rack 401 and sleeved on the two connecting shafts 410, and then the cover plate 403 is turned over and rotated to connect with the retracting rack 401, so as to limit the yellow tape roll 404 and the take-up roller 405 inside the retracting rack 401.

[0057] When the yellow tape wrapped around the yellow tape roll 404 needs to be hung, one end of the yellow tape is removed from the yellow tape roll 404 by moving, and then the handle 56 is moved to use the slide 51 to drive the spring 53 and the pressure roller 54 to move. The moving spring 53 is compressed, and the moving pressure roller 54 drives the anti-sticking film 55 to separate from one side of the roller 303, so that one end of the yellow tape can pass through the two pressure rollers 54 and the anti-sticking film 55 in turn, and be wound in the yellow tape support frame 301. Then, one end of the yellow tape is wound around the tape take-up roller 405 and fixed, and the initial hanging and winding operation of the yellow tape is completed. The roller 303 is used to rotate under the action of friction to reduce the friction of the yellow tape when it is wound on the yellow tape support frame 301, making the yellow tape hanging operation easier and more convenient.

[0058] When the yellow belt hanging and winding operation is completed, the internal threaded sleeve 203 is rotated to use the thread and positioning block 204 to drive the wire rope 202 to move, so that the hanging height of the yellow belt can be adjusted according to the growth of the crops, so that the hanging yellow belt is located 20-40CM above the crops.

[0059] When the yellow tape has been used for a long time and its insect attracting and sticking effects are reduced, the output shaft of the reduction motor 406 drives the first gear 407 to rotate, and the rotating first gear 407 drives the two connecting shafts 410 to rotate using the second gear 408 and the third gear 409. One rotating connecting shaft 410 drives the yellow tape roll 404 to release the yellow tape, and the other connecting shaft 410 rotating in the opposite direction drives the tape take-up roller 405 to rewind the used yellow tape, thereby completing the recycling of the used yellow tape at the same time. The hanging and winding operation of the new yellow tape is carried out by providing a slide 51 to use the compressed spring 53 to provide continuous thrust to the pressure roller 54, so that the yellow tape can be squeezed and fitted into the yellow tape support frame 301 by the pressure roller 54 using the anti-sticking film 55, so as to ensure the stability of the yellow tape during movement, and prevent the used yellow tape from detaching from the yellow tape support frame 301 when replacing the new yellow tape roll 404, and then the new and old yellow tapes can be connected by bonding, so as to complete the laying of the new yellow tape while winding up the old yellow tape.

[0060] The above are merely specific embodiments of the present invention, but the scope of protection of the present invention is not limited thereto. Any person skilled in the art can easily conceive of various variations or substitutions within the technical scope disclosed in the present invention, and such variations or substitutions are intended to fall within the scope of protection of the present invention. Therefore, the scope of protection of the present invention shall be subject to the scope of protection of the claims.
