Description

Technical Field

[0001] An adjustable device for sticky insect traps in greenhouses belongs to the field of greenhouse planting technology. Background Technology

[0002] In greenhouses, several sticky insect traps need to be set up to capture flying insects and reduce their damage to crops. These traps are usually yellow because flying insects are sensitive to yellow and are attracted to them. To facilitate insect capture, the traps are typically suspended by ropes from the top of the crops, with the traps positioned on the side closest to the walkway where the view is clearer and the insects are more easily caught.

[0003] As crops grow in the greenhouse, the height of the sticky insect traps needs to be adjusted. Currently, this is mainly done manually. Since there are many sticky insect traps in the greenhouse, a lot of manpower and time are needed to adjust them. In addition, since the sticky insect traps are placed on the side near the aisle, it is easy to touch the sticky insect traps when operating crops, which causes inconvenience to the operation in the greenhouse. Utility Model Content

[0004] The technical problem to be solved by this utility model is to overcome the shortcomings of the existing technology and provide a greenhouse sticky insect board adjustment device that can conveniently adjust the sticky insect boards in the greenhouse, saving labor and costs.

[0005] The technical solution adopted by this utility model to solve its technical problem is as follows: The greenhouse sticky insect board adjustment device includes a winding and unwinding roller, a hanging rope, and several support rods arranged along the length of a row of crops. Multiple sticky insect boards are provided on the lower side of the support rods. One end of the hanging rope is connected to the winding and unwinding roller, and the other end of the hanging rope passes around the support rod and is connected to the sticky insect board. The hanging ropes on each support rod are parallel and spaced apart. The winding and unwinding roller is connected to a winding and unwinding motor that drives its rotation.

[0006] Preferably, a counterweight is provided at the connection between the hanging rope and the sticky insect board, or a counterweight is provided on the sticky insect board.

[0007] Preferably, the counterweight is a hook, the upper end of which is connected to a hanging rope, and the upper part of the sticky insect board is provided with a connecting hole for connecting the hook.

[0008] Preferably, the take-up and undo reel is provided with retaining rings, and one end of the suspension rope is connected to the take-up and undo reel between two retaining rings.

[0009] Preferably, the retaining ring has an expansion joint, and a force-applying protrusion is provided on at least one side of the retaining ring along the expansion joint. This facilitates fixing the retaining ring to the take-up / untake-off reel or removing the retaining ring from the take-up / untake-off reel.

[0010] Preferably, the support rod is provided with a grooved wheel, and the suspension rope is wound around the inside of the grooved wheel.

[0011] Preferably, the support rod is further connected to a position adjustment mechanism, which adjusts the horizontal position of the support rod.

[0012] Preferably, the position adjustment mechanism includes a swing rod, a fixed rod, an adjusting rod, and a column. The fixed rod is arranged parallel to the support rod. The middle part of the swing rod is rotatably arranged. One end of the swing rod is connected to the support rod, and the other end is connected to the adjusting rod through a pull rope. The middle part of the pull rope is arranged to pass around the fixed rod. The column is provided with multiple hooks, and the adjusting rod is fixed to the lower side of the hooks.

[0013] Preferably, a swing arm is connected to each end of the support rod.

[0014] Preferably, the support rod is disposed between the fixed rod and the take-up / unwind reel.

[0015] Compared with existing technologies, the beneficial effects of the above-mentioned technical solution of the greenhouse sticky insect board adjustment device are:

[0016] This invention allows for the overall height adjustment of all sticky insect traps within a greenhouse via a retractable roller, ensuring the traps are positioned at a suitable height for the crops, thus improving insect capture efficiency. The adjustment is convenient and saves labor. Furthermore, because the height of the sticky insect traps is automatically adjustable, they can be placed directly above the center of the greenhouse aisles, making it easier to capture flying insects. During operation, simply adjust the traps upwards.

[0017] Inside the greenhouse, there is also a position adjustment mechanism for adjusting the horizontal position of the support rod. This mechanism can be used to adjust the support rod from the middle of the walkway to one side, and adapt to different needs for the horizontal position of the sticky insect board, so as to meet the needs of different crops for capturing flying insects.

[0024] Figures 1-5 This is the optimal embodiment of the adjustable sticky insect board device for the greenhouse, as detailed below in conjunction with the attached document. Figures 1-5 The present invention will be further described below.

[0025] Reference Figure 1-2 The greenhouse sticky insect trap adjustment device includes a retractable roller 1, a hanging rope 4, and several support rods 3 arranged along the length of a row of crops. Multiple sticky insect traps 5 are located on the lower side of the support rods 3. One end of the hanging rope 4 is connected to the retractable roller 1, and the other end of the rope 4 passes over the support rods 3 and connects to the sticky insect trap 5. The retractable roller 1 is connected to a motor 2 that drives its rotation. The motor drives the retractable roller 1 to rotate, thereby retracting and extending the hanging rope 4, ultimately adjusting the height of the sticky insect trap 5.

[0026] The hanging ropes 4 on each support rod 3 are parallel and spaced apart to prevent the ropes of different sticky insect boards 5 from getting tangled together, ensuring reliable deployment and retrieval.

[0027] In this embodiment, the support rod 3 is also connected to a position adjustment mechanism, which adjusts the horizontal position of the support rod 3. This mechanism allows the support rod 3 to be adjusted from the center of the walkway to one side, adapting to different requirements for the horizontal position of the sticky insect board 5, and thus meeting the needs of different crops for capturing flying insects.

[0028] Specifically, the position adjustment mechanism includes a swing rod 6, a fixed rod 9, an adjusting rod 10, and a column 11. The fixed rod 9 is arranged parallel to the support rod 3. The middle part of the swing rod 6 is rotatably arranged. One end of the swing rod 6 is connected to the support rod 3, and the other end is connected to the adjusting rod 10 through a pull rope 8. The middle part of the pull rope 8 is arranged to pass around the fixed rod 9.

[0029] A swing rod 6 is connected to each end of the support rod 3. The middle part of the swing rod 6 is fixedly connected to the rotating shaft 7, which is set parallel to the support rod 3. The support rod 3 is positioned between the fixed rod 9 and the take-up and release roller 1. When the support rod 3 is horizontally close to the crop, the take-up and release roller 1 is not working, and the length of the hanging rope 4 remains unchanged. At this time, the sticky insect board 5 tends to move downwards. However, because the swing rod 6 drives the support rod 3 to move upwards, the height of the sticky insect board 5 remains basically unchanged as it approaches the crop.

[0030] See Figure 3The support rod 3 is equipped with a grooved wheel 14, and the lifting rope 4 is wound around the inside of the grooved wheel 14. The grooved wheel 14 ensures that the position of the lifting rope 4 on the support rod 3 is fixed, and prevents adjacent lifting ropes 4 from getting tangled together.

[0031] A counterweight is provided at the connection point between the hanging rope 4 and the sticky insect board 5, or a counterweight is provided on the sticky insect board 5. The counterweight ensures that the sticky insect board 5 can fall smoothly when it is lowered, and prevents the sticky insect board 5 from drifting inside the greenhouse due to spraying. Specifically, in this embodiment, the counterweight is a hook 13, the upper end of which is connected to the hanging rope 4, and the upper part of the sticky insect board 5 is provided with a connecting hole for connecting the hook 13.

[0032] See Figure 4 The take-up and take-down reel 1 is equipped with a retaining ring 15, and one end of the suspension rope 4 is connected to the take-up and take-down reel 1 between two retaining rings 15. The retaining ring 15 is provided with an expansion joint 16, and a force-applying protrusion 17 is provided on at least one side of the retaining ring 15 of the expansion joint 16. The force-applying protrusion 17 facilitates the widening of the expansion joint 16, thereby directly fixing the retaining ring 15 to the take-up and take-down reel 1.

[0033] See Figure 5 The column 11 is equipped with multiple hooks 12, and the adjusting rod 10 is fixed to the lower side of the hooks 12. By pulling the rope 8 with the adjusting rod 10, the rope 8 drives the swing rod 6 to swing, and the swing rod 6 drives the adjusting rod 10 to swing. The height can be adjusted at the same time as adjusting the horizontal position of the sticky insect board 5.

[0034] Working process: The reel 1 is rotated by the reel motor 2, which can adjust the height of all the sticky insect boards 5 in the greenhouse, placing them at a suitable height for the crops to improve the insect capture effect. The adjustment is convenient and saves labor. When the sticky insect board 5 needs to be adjusted to a horizontal position, the adjusting rod 10 drives the swing rod 6 to swing via the pull rope 8. This allows for both horizontal and height adjustment of the sticky insect board 5. After adjustment, the adjusting rod 10 is fixed to the lower side of the corresponding hook 12, adapting to different horizontal position requirements of the sticky insect board 5 and meeting the needs of capturing flying insects for different crops.

[0035] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of this utility model without departing from its technical solution shall still fall within the protection scope of this utility model.
