Description

Technical Field

[0001] The invention relates to a hand-push type oil-tea fruit collecting device, belonging to the technical field of equipment manufacturing. Background Art

[0002] The oil tea tree is an evergreen shrub of the genus Camellia in the Theaceae family. The oil tea tree, oil palm tree, olive tree and coconut tree are known as the world's four major woody edible oil tree species. The oil tea fruit of its fruit is of very high value. It can not only be used to extract oil, but also has very high medicinal value.

[0003] In my country, tea trees are mostly planted in hilly and mountainous areas, with a wide planting area, lush growth, many branched branches, and high yields. Since tea trees are mostly planted in hilly and mountainous areas, the terrain is undulating, the terrain is complex and changeable, and there are limited management personnel. Tea trees basically grow naturally and are managed extensively. The branches are many and the branches at the bottom of the main trunk of the tree are very close to the ground. Every year during the tea fruit harvesting and picking season, conventional tea fruit collection devices cannot get close to the tree, and the collection effect is poor for some irregular branches and fruits on the forks at the bottom of the main trunk. Fruit collection is difficult, and a large number of mature fruits are scattered under the tree, causing waste.

[0004] In addition, common camellia fruit collecting devices generally have problems such as complex structure, large size, difficulty in transporting up the mountain, and inconvenience in walking on complex terrain. For example, the patent application for an automatic camellia fruit collecting machine, with the publication number CN117158191A, was submitted by Chen Hong of Huazhong Agricultural University. The automatic camellia fruit collecting machine adopts crawler self-propelled walking, with a complex overall structure, difficulty in transporting up the mountain, poor flexibility under mountainous conditions, and the movement of the umbrella ribs is completed by an electric push rod in conjunction with a gear rack, which is relatively complicated and has a high failure rate.

[0005] The patent application for a tea fruit collecting device is CN117441488A, and the invention name is submitted by Yu Hang et al. of the Wood Industry Research Institute of the Chinese Academy of Forestry. The tea fruit collecting device requires manual deployment of the umbrella to collect the tea fruits, which is cumbersome to operate.

[0006] For example, the patent application for a circular expandable camellia fruit collecting device, which is published as CN116711542A, was filed by Tang Lewei et al. of Hunan Agricultural University. The scissor-fork structure of the camellia fruit collecting device is complex, and the flexibility of the whole machine is poor.

[0007] For example, the patent application with publication number CN201216070Y, titled "Inverted umbrella-shaped fruit-catching device" submitted by Tang Zhihui et al. from the Institute of Agricultural Machinery of Xinjiang Academy of Agricultural Reclamation Sciences, is a device that expands and contracts through a hydraulic cylinder and drives the rack and pinion to unfold the umbrella. It has a complex structure and a high failure rate.

[0008] For example, the patent application for an inverted umbrella-shaped oil-tea fruit collecting device filed by Rao Honghui of Jiangxi Agricultural University, with publication number CN208095231U, requires manual pulling of the pull rod to drive the umbrella ribs to rotate, close the umbrella surface, and surround the fruit tree, which is cumbersome to operate.

[0009] For example, Yang Jialin et al. from Jiangxi Agricultural University published a paper titled "Design and Experiment of a Portable Camellia Oil Fruit Collection Device". The study designed a portable umbrella-shaped Camellia Oil Fruit Collection Device. The Camellia Oil Fruit Collection Device has a complex structure, and is difficult to operate in terms of umbrella folding, height adjustment, and angle adjustment. It has poor collection effect on Camellia Oil Fruit trees with irregular trunks. Summary of the invention
