초록

This study was carried out to develop a belt pick-up type two-row soybean reaper, using physical properties and production conditions of soybeans. The prototype soybean reaper consisted of 4 parts: cutting part, conveying part, collecting part, and travelling part. The prototype soybean reaper was designed to cut soybeans planted with a row spacing of 400 ㎜, and at a height of 30 ㎜ from the bed bottom using two disk saws. Through various trials with different peripheral velocities of the disk saw and forward speed of the soybean reaper, determined ranges of the peripheral velocity of the disk saw cutting soybeans stems were greater than 18.3 ㎧. Spacing between pick-up belts (clearance) was in a range of 60-120 ㎜ and the size and shape of the pick-up belt were determined the conventional manual harvesting method. The optimal ratio between the forward speed of reaper and the peripheral speed of pick-up belts were from 1 to 1.2 by theoretical analysis. the pick-up belts had a 35° of tilted angle to pick up soybeans safely from the plant input to the lower end of the belts and convey soybeans to the upper end of belts nearby a container. The soybeans at the rear container were dropped down on the soybean row with an interval. The effective field capacity of the prototype soybean reaper was 0.196 ha/h, reducing the working hour by 94% when compared with the manual cutting.
