The demand of forestry seeds also increased. In order to meet the needs of the forestry production, meet the requirements of high-speed development of forestry and forestry modernization, especially the seed seed work must continue to improve management level. Scientific seed, mechanization seed instead of heavy manual seed, is receiving more and more attention. Portable forestry seed harvesters can adapt to various complicated environment with high efficiency, very suitable for Chinas national conditions. Based on the complex terrain, wooded mountain environment has an irreplaceable advantage. In this paper, the specific design of the portable forestry seed harvesters. Completed the portable forestry seed harvesters theory analysis, calculation and structural design. Including the portable forestry seed harvesters overall design, engine selection, clutch design, shaft design, the design of the vibration head. The working principle of portable forestry seed harvesters is driven by the engine clutch is connected through a flexible shaft, gear and transmission rod is connected to the slider, rotary motion into li
