Description

Technical Field

[0001] The utility model belongs to the technical field of forestry bird-repelling equipment, and in particular relates to bird-repelling equipment based on a bionic bird mechanism. Background Art

[0002] With improvements in the ecological environment both domestically and internationally and growing public awareness of bird protection, the number of birds has increased, causing significant damage to fruit trees and placing immense pressure on orchards. Bird damage to orchards is increasing, severely impacting fruit yield and quality, and causing significant economic losses for fruit growers. To control bird damage, fruit growers invest heavily in bird control each year. Surveys show that annual fruit yield losses due to bird feeding are as high as 20% for early-maturing varieties, 5% for mature varieties, and even 30% for low-quality fruit. This severely impacts fruit quality and yield, reducing farmers' incomes. Bird feeding not only affects fruit quality and yield but also creates secondary damage. The pecked fruit is susceptible to pathogens, which multiply rapidly in the wounds, attracting flies and insects. This can cause disease in otherwise healthy fruit, exacerbating the spread of pathogens and contributing to the occurrence of fruit tree diseases. Furthermore, bird activity can cause severe damage to spring fruit tree branches, buds, and grafted stems, directly impacting the economies of major fruit-producing regions. Researchers in fields like agriculture and ecology often cultivate or raise specific plants and animals as research materials. When these materials (such as mature sorghum or crops in experimental fields) become targets for birds, they can consume them in large quantities, preventing researchers from collecting sufficient data or samples, thus impacting the effectiveness of their research. Faced with this damage, fruit farmers are at a loss, and traditional bird-repelling methods are ineffective in mitigating local losses. In plain areas, orchards are vast, requiring significant labor and time to maintain these vast expanses, resulting in less effective bird-repelling efforts. In mountainous areas, access to these orchards is difficult, making bird-repelling even more challenging and a significant source of frustration for farmers. Therefore, it is of positive practical significance and also of great necessity to improve the existing orchard bird-repelling equipment and innovate a bird-repelling equipment to achieve simple structure and high efficiency in bird-repelling.

[0036] The bionic bird-like bird-repellent device uses a support and conveying device, a tensioning device, and a suspension and lifting device to achieve reciprocating motion in the horizontal and vertical directions. A controller controls this reciprocating motion, creating an irregular pattern. This results in a flight pattern that fluctuates between fast and slow, high and low. Combined with a mouth opening and closing device, a head rotation device, and wing transmission devices, the device mimics the full-body movements of a bird, specifically the ability to soar high, descend low, wag its head and tail, and swing its body side to side. The uncertainty of the bionic bird-like bird-repellent device's motion makes its operation irregular, making it difficult for birds in orchards to form conditioned reflexes.
