Description

Technical Field

[0001] The utility model belongs to the technical field of oil-tea fruit picking, and in particular relates to a hand-push type oil-tea fruit picking machine. Background Art

[0002] The oil-tea industry has become an important pillar for the development of my country's forestry economy and the increase of farmers' income. The problem of oil-tea fruit harvesting has seriously hindered its industrial development. Oil-tea is mostly planted in hilly and mountainous areas, and special requirements are placed on oil-tea fruit harvesting machinery, such as flexible operation and compact size. At present, manual harvesting of fallen oil-tea fruits is inefficient and labor-intensive. Existing studies mostly use methods such as beating and vibration to make mature oil-tea fruits fall to the ground, without considering the collection of fallen oil-tea fruits. Although some studies have collection mechanisms, the equipment is large in size and high in cost. On the other hand, before the oil-tea fruits are harvested, some oil-tea fruits will mature prematurely and fall naturally, increasing the cost of picking up and the losses of growers. The picking of oil-tea fruits has become an important problem that needs to be solved urgently in the current harvesting process.

[0003] Aiming at the problems of manual picking consuming manpower and mechanical picking having high requirements on forest environment in the picking of oil tea fruit, Patent CN111194615A discloses a ground-based forest fruit picking robot, which completes the picking and collecting work through a picking cage and a fruit collector, but the whole machine is large in size, the picking cage has a small capacity, the missed picking rate is high, and the energy consumption is high. Patent CN115968656A discloses an integrated machine for picking and preprocessing fresh oil tea fruit, which completes the picking of oil tea fruit under the tree crown through the cooperation of a gathering disk and a picking roller, but the equipment is large and the cost is high, and it is not easy for small and medium-sized growers to use.

[0004] The current machinery for picking up fallen tea fruits has low efficiency, large size and high cost. Therefore, there is an urgent need to develop a mechanical equipment for picking up fallen tea fruits that has high picking efficiency, is lightweight and energy-saving. This will have important research value and application prospects for promoting the mechanized picking of tea fruits. Utility Model Content

[0009] Preferably, the auxiliary wheel consists of a rubber tire, a wheel hub, a mounting hole and a fruit outlet; the rubber tire is installed on the circumference of the wheel hub; four fan-shaped fruit outlets are evenly arranged along the circumference of the wheel hub center and are installed at both ends of the feed shaft by keys; the mounting holes are distributed along the circumference near the fan-shaped outlet of the wheel hub.

[0010] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0011] (1) The utility model is designed based on the material characteristics of tea fruit. The rubber rod of the picking mechanism is deformed after encountering the fallen tea fruit, and the picking is completed under the wrapping effect of the adjacent rubber rods, which can effectively reduce the missed picking rate and greatly reduce the manual picking labor; (2) The utility model has strong terrain adaptability and can set the gap between the rubber rods of different picking mechanisms according to the conditions of the planted forest.
