Description

Technical Field

[0001] This utility model relates to the field of agricultural machinery, and more specifically, to a handheld harvesting device. Background Technology

[0002] Traditional seed harvesting equipment typically relies on large-scale mechanized machinery, using tractor-mounted harvesting platforms to achieve large-scale harvesting of tall, densely growing crops. However, such equipment has significant limitations when dealing with short-stalked, dispersed crops like milkvetch. Milkvetch plants are characterized by short stems, scattered branching, uneven seed pod distribution, and a tendency to crack easily. Large harvesting devices struggle to accurately locate effective seed pods, leading to missed pods or seed loss during operation. Furthermore, the harvested material contains a large amount of stem impurities, increasing subsequent cleaning costs. Simultaneously, traditional equipment is bulky and cumbersome, unsuitable for small-scale planting and unable to maneuver flexibly in complex terrain, resulting in high purchase costs and low utilization rates. Currently, there are no lightweight, dedicated harvesting tools available for such crops, forcing farmers to rely heavily on manual harvesting, which suffers from low efficiency, high labor intensity, and unsatisfactory seed collection rates.

Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. The components of the embodiments of this application described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0027] Therefore, the following detailed description of the embodiments of this application provided in the accompanying drawings is not intended to limit the scope of the claimed application, but merely to illustrate selected embodiments of the application. All other embodiments obtained by those skilled in the art based on the embodiments of this application without inventive effort are within the scope of protection of this application.

[0028] Please refer to Figures 1 to 3 In a preferred embodiment, the handheld harvesting device of this utility model mainly includes a handheld component 1 and a cutting component 2. The handheld component 1 includes a rod 11, a power supply battery 12 detachably connected to the rod 11, and a handheld part 13 disposed on the rod 11. The cutting component 2 is disposed at one end of the rod 11 and includes a protective cover 21, a blade assembly 22, a drive assembly 23, and a seed bag 24. The protective cover 21 is rotatably connected to the rod 11. The blade assembly 22 and the drive assembly 23 are disposed inside the protective cover 21. The seed bag 24 is detachably connected to the protective cover 21 and is located below the blade assembly 22.

[0029] For example, the pole 11 can be a telescopic pole, allowing for flexible adjustment of the operating distance according to crop height and working environment, while significantly reducing the storage volume when not in use and improving transportation convenience.
