Abstract
Description
Technical Field
[0001] This utility model relates to the field of bird netting technology, and in particular to a detachable bird netting. Background Technology
[0002] Bird netting is a mesh fabric made primarily of polyethylene and heddles. Covering the erected sheds with bird netting creates an artificial barrier, preventing birds from flying into the pear orchard. This effectively controls birds from damaging the pears and is environmentally friendly and pollution-free. It also has the function of resisting natural disasters such as hail.
[0003] To address this, patent CN213281277U discloses a bird-proof netting device, which is fixedly installed at the inside corner formed by the eaves and wall outside a poultry farm. The bird-proof netting device includes an inclined net body, with its two ends connected to the eaves and wall respectively. Because the inclined net body is unfavorable for birds to perch between the eaves and wall, it can prevent birds from nesting between the eaves and wall.
[0004] Existing bird netting is inconvenient to retract and extend during installation, and its length cannot be adjusted as needed, which affects the installation effect and reduces installation efficiency. Utility Model Content
[0005] The purpose of this invention is to provide a detachable bird net to solve the problem that existing detachable bird nets are inconvenient to put away and take off.
[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a detachable bird net, including a fixing frame, a winding shaft installed inside the fixing frame, a bird net body installed on the winding shaft, a driving structure provided at one end of the winding shaft, the driving structure including a second gear installed on the upper end of the winding shaft, a first handle installed on the top of one side of the fixing frame and a first gear installed at one end of the first handle, a fixing structure provided at the top of the other side of the fixing frame, a protective shell installed at one end of the fixing frame, a positioning groove opened on one side of the fixing frame, and a cleaning structure provided on the inner wall of the positioning groove.
[0007] Preferably, the first gear meshes with the second gear.
[0008] With the above structure, turning the handle causes the first gear to drive the second gear to rotate, allowing the winding shaft to rotate.
[0009] Preferably, a second limiting block is symmetrically installed on one end of the protective shell, and a first limiting block is installed on the top of one side of the protective shell, and a limiting hole is provided on the first limiting block.
[0010] With the above structure, the second limiting block can limit the winding shaft, and the limiting hole allows the adjusting rod to pass through.
[0011] Preferably, the cleaning structure includes a limiting groove, a limiting spring, and a brush. The limiting groove is formed on the inner wall of the positioning groove. Limiting springs are evenly installed inside the limiting groove, and a brush is installed at one end of each limiting spring.
[0012] The above structure allows for the cleaning of bird netting, improving its effectiveness.
[0013] Preferably, one end of the brush is disposed in the limiting groove, and the brush and the limiting spring form a telescopic structure.
[0014] Through the above structure, the limiting spring moves the brush, causing it to come into contact with the bird net.
[0015] Preferably, the fixing structure includes a second handle and an adjusting rod, the adjusting rod being installed at the top of the other side of the fixing frame, and a handle being installed on one side of the adjusting rod.
[0016] The above structure allows the take-up shaft to be fixed in place.
[0017] Preferably, the top and bottom of the fixing frame are provided with slots, and the top and bottom of the winding shaft are inserted into the slots and slidably connected thereto.
[0018] The above structure allows the slot to position the take-up shaft to a certain extent.
[0019] The advantages of the detachable bird net provided by this utility model are as follows:
[0020] The bird netting can be wound up and down by rotating the winding shaft through the drive structure, and the length of the bird netting can be adjusted to meet different laying requirements. The fixing structure can fix the winding shaft, and the cleaning structure can clean the bird netting to improve its effectiveness.
[0021] Through the set drive structure, turning the first handle drives the second gear to rotate, and the winding shaft rotates. During the rotation of the winding shaft, the bird net can be retracted and extended to adjust the length of the bird net to meet different laying requirements.
[0022] By using the fixed structure, rotating the second handle moves the adjusting rod until it passes through the limiting hole and abuts against the second gear, thus achieving the purpose of fixing the protective shell and the winding shaft, and releasing the fixed restriction on the protective shell and the winding shaft so as to disassemble the bird net.
[0023] The cleaning mechanism uses a limit spring to move the brush, bringing it into contact with the bird netting. When the bird netting is being raised or lowered, the brush can remove dust from the netting, thus cleaning it. Attached Figure Description
