This paper analysed and studied the relationships between structures and power parameters of type of cylinder, the velocity of feed chain, rpm of cylinder, type of threshing and feed rate to the threshing loss and power consumption in semi-feeding threshing apparatus. As well as the three kinds of concaves have an influence upon the threshing loss and grain-cleaning rate.The experiment has proved that the side-threshing is optimal to the semi-feed threshing type. Either wheat or rice threshing can be obtained...

This paper analysed and studied the relationships between structures and power parameters of type of cylinder, the velocity of feed chain, rpm of cylinder, type of threshing and feed rate to the threshing loss and power consumption in semi-feeding threshing apparatus. As well as the three kinds of concaves have an influence upon the threshing loss and grain-cleaning rate.The experiment has proved that the side-threshing is optimal to the semi-feed threshing type. Either wheat or rice threshing can be obtained result ideal while the velocity of chain is 0.75~0.85m/sec., linear velocity of cylinder is 14-17m/sec. and the feed rate is less than 2 kg/sec. It is difficulty to increase the feed-rate for wheat threshing based on the present threshing mechanism.By means of high-speed photgraph. we observed the threshing process of "bowteeth" cylinder to thresh wheat and rice. In threshing functions, the rice is threshed by combing action and the wheat is threshed by impact action.

本文分析研究了半喂入脱粒部件的滚筒型式、夹持链速度、滚筒转速,脱粒方式及工作量等的结构和动力参数对脱粒损失和功率消耗的影响,以及三种不同型式的凹板对脱粒损失和籽粒清洁度的影响。 试验表明,半喂入脱粒方式以侧脱为最佳、夹持链输送速度在0.75~0.8米/秒时,滚筒的线速度在14~17米/秒时,工作最在2公斤/秒以内,脱稻、麦均能达到理想效果。在现有结构上再增加工作量脱小麦有一定困难。 另外,通过高速摄影,观察了弓齿型滚筒脱稻、麦时的脱粒全过程。清楚的反映出脱水稻是靠弓齿的梳刷作用,脱小麦是靠弓齿的打击作用。

Based upon analysis of the relation between kinematical of rake finger and crops, two fundamental equations are derived. According to these equations, this paper discusses and suggests three parameters. The rake finger is opened up atψ = 80°~π/2 to reduce K(ratio between kinematical velocity of rake finger and forward velocity of semi-feed combine). θ(inclination of the stalk lifter)in a range from 60° to 65° and K from 1.44 to 3.51 can adapt better to the harvesting of wheat and dwarf rice.These estimate...

The position of rakestar-wheel is also discussed.
