A single locking cotton feeder was designed to maintain a constant feed rate of individual pods at the ginning point of the double roller (DR) cotton gin. It consists of a pair of feed rollers, spike cylinders, grids, feed hoppers and distribution chutes. The spike cylinder has spikes, the tips of which are closer to the supply roller than the fixed thickness of cotton and have a ginning interval. The spike cylinder travels at a linear speed greater than the feed roller, whereby the cotton pods held between the feed rollers are hit by the spikes of the spike cylinder, thus ensuring a single locking of the cotton. The effect of single locking on the ginning efficiency of the DR cotton gin was investigated. The degree of unlocking was determined by measuring the change in cotton bulk density before and after passing through the feeder, which decreases with increasing spike cylinder speed. It was found that the DR cotton gin output was increased by 15 to 20% by adopting a single locking compared to the conventional feeding system consisting of an auto feeder and a micro feeder. Cotton quality was also found to improve in color grade. A single locking feeder has proved to be very useful in the cotton gin industry in India.
Maize harvest was a bottleneck for maize-scale production in the Huanghai Plain. Factors influencing the harvest of corn grains are: the biomechanical properties of corn and the technical parameters of the harvesting machine. In this study, we described how the threshing system is established in the combination of tangential flow and lateral axial flow. Shell grain damage rate was selected as the goal of this experimental study, and variation in the goal was investigated in relation to the biological properties of maize. Threshing experiments were performed to determine the effect of the main biological factor, the water content of the grains. After that, the main technical parameters were defined for the peripheral velocity of the threshing drum. The feed amount was economically maintained at 2.6 kg · s -1, and in this study, the threshing clearance was maintained at 36 mm for corn ears of average diameter. When the water content was 28% or less, the threshing ability of the tangential flow drum was similar to that of the axial flow drum. When the water content was 28% or more, the threshing ability of the tangential flow drum decreased significantly. When the water content is 24-26% and the peripheral velocity of the axial threshing drum is 17.28 m / s -1, the minimum value of the shell grain damage rate of the threshing system is 1.7%, which is the minimum value. there were.
