中文摘要:基于矩形循环图法,设计了一种籽瓜挖瓤机。上瓜机构采用改进的摆动凸轮机构,插瓜架转位机构选择两圆销四槽轮机构,挖瓤刀升降机构选取平底式直动从动件盘形凸轮机构与改进的杠杆传动。以试验机为基础进行籽瓜挖瓤正交试验,确定了适合籽瓜挖瓤的工艺参数:挖刀类型为半圆形挖刀、挖刀转速为240r/min、挖刀安装角度为15°。重复试验表明:该挖瓤机挖净率在98%以上,籽粒洁净率在98%以上,损失率在2%以内,破碎率小于1%。

Abstract:Based on rectangle circulating chart method, a seed melon pulp-excavated machine was designed. Improved swinging cam was used for feeding melon mechanism, a 2-round pin and 4-grooved wheel mechanism were chosen to realize precise indexing motion of a plug melon saddle, and flat-bottom tappet disc cam mechanism with improved rod gear mechanism was used for lifting tool saddle. The orthogonal experiment was done and the optimum parameters of digging was discovered as follows: the type of digging tool is hemicycle, the speed of digging tool is 240r/min and the installation angle of digging tool is 15°. Replicated tests showed the cleaning rate is more than 98%, grain seedless rate is more than 98%, loss rate is less than 2% and broken rate is less than 1%, respectively.

Transactions of the Chinese Society for Agriculture Machinery (CSAM), in charged of China Association for Science and Technology (CAST), sponsored by CSAM and Chinese Academy of Agricultural Mechanization Science(CAAMS), started publication in 1957. It is the earliest interdisciplinary journal in Chinese which combines agricultural and engineering. It always closely grasps the development direction of agriculture engineering disciplines and the published papers represent the highest academic level of agriculture engineering in China. Currently, nearly 8,000 papers have been already published. There are around 3,000 papers contributed to the journal each year, but only around 600 of them will be accepted. Transactions of CSAM focuses on a wide range of agricultural machinery, irrigation, electronics, robotics, agro-products engineering, biological energy, agricultural structures and environment and more. Subjects in Transactions of the CSAM have been embodied by many internationally well-known index systems, such as: EI Compendex, CA, CSA, etc.
