Patent number: 11470771Abstract: A ground-contour-following autonomous obstacle avoidance mower for hillside orchards and a control method thereof are provided to achieve multi-angle cutting and low energy consumption in mowing operation through cooperation of a push rod motor and a connecting-rod rotating pair. A connecting rod is arranged and forms a flexible mechanism together with an upper base bearing, a lower base bearing and a base-connecting unthreaded shaft. The flexible mechanism interacts with the push rod motor to achieve ground contour following operation, so that the mower as a whole can conduct ground-contour-following mowing operation on a complex orchard terrain, with a better cutting effect than that of a traditional mower.Type: GrantFiled: June 11, 2020Date of Patent: October 18, 2022Assignee: Jiangsu UniversityInventors: Xianping Guan, Zhipeng Liu, Fubin Dai, Baijing Qiu, Xiaoya Dong

Publication number: 20220124974Abstract: The present invention provides a ground-contour-following autonomous obstacle avoidance mower for hillside orchards and a control method thereof. Through cooperation of a push rod motor and a rotating pair, multi-angle cutting is achieved, and energy consumption needed by mowing operation is reduced. A connecting rod is arranged and forms a flexible mechanism together with an upper base bearing, a lower base bearing and a base-connecting unthreaded shaft. The flexible mechanism interacts with the push rod motor to achieve ground contour following operation, so that the mower as a whole can conduct ground-contour-following mowing operation on a complex orchard terrain, with a better cutting effect than that of a traditional mower. The use of a right-angle bypassing obstacle avoidance mode realizes precise obstacle avoidance of the mower, and achieves the operation purpose of not excessively relying on operators.Type: ApplicationFiled: June 11, 2020Publication date: April 28, 2022Applicant: Jiangsu UniversityInventors: Xianping GUAN, Zhipeng LIU, Fubin DAI, Baijing QIU, Xiaoya DONG

Publication number: 20210056685Abstract: An apparatus for monitoring comprehensive growth condition of potted lettuce consists of a polarized hyperspectral imaging system and a 3D laser scanning system. The polarized hyperspectral imaging system includes a control system, a dual-coordinate sample holder, an image acquisition system, and a light source system, and the polarized hyperspectral imaging system detects water and fertilizer stress in lettuce by polarized hyperspectral multi-dimensional reflection imaging of characteristics on a canopy/leaf scale. The 3D laser scanning system detects morphological characteristics such as the biomass, stem diameter, plant height, and leaf area of lettuce.Type: ApplicationFiled: December 19, 2017Publication date: February 25, 2021Applicant: JIANGSU UNIVERSITYInventors: Xiaodong ZHANG, Xuewei ZHANG, Hanping MAO, Baijing QIU, Hongtao ZHANG, Zhiyu ZUO, Hongyan GAO, Jiheng NI, Yixue ZHANG, Fang ZHANG

Patent number: 10773803Abstract: An automatic degradable sphere distributing device for an unmanned aerial vehicle, relating to the technical field of plant protection mechanism. Said distributing device comprises a ranking portion, an adjustment portion and a distributing portion. The ranking portion consists of a rotating shaft (2), blades (1a, 1b), a rolling bearing (12), a sphere cabinet (3), a coupling (9b), a motor support (11b) and a motor (10b). The adjustment portion consists of a housing (501), a bevel gear transmission group (502, 503) and adjustment sheets (504a, 504b, 504c). The distributing portion consists of circular wheels (8a, 8b), a spur gear group (6a, 6b), a guide rod (13), a coupling (9a), a motor support (11a) and a motor (10a). Said distributing device may rank the degradable spheres vertically in sequence, being adaptable to spheres of different volumes, being highly universal, and being capable of distributing the spheres at intervals, with high precision and automation degree.Type: GrantFiled: November 10, 2015Date of Patent: September 15, 2020Assignee: JIANGSU UNIVERSITYInventors: Baijing Qiu, Xiang Tong
