鸡蛋鸭蛋人人爱吃,可是要把散在地上的鸭蛋一个一个的捡拾收集起来,却不是一件轻松而愉快的劳动。我校学生彭彩艳的叔公家是养凫鸭的专业户,她见叔公每天要从鸭棚里捡回150～160个鸭蛋,上了年纪的人,弯腰拱背用手捡蛋,劳动强度大,效率又不高,非常辛苦。她就为叔公制作了一个拾蛋器。这种拾蛋器在84年全国第二届青少年科学发明比赛和科学讨论会上荣获了二等奖。有了拾蛋器,捡蛋者就可站着工作了,而且还能提高捡蛋的工效,所以饲养家禽的专业户非常喜爱。我校科技小组听取了几个养鸭专业户的意见,对彭彩艳同学发明的拾蛋器进行了改进,制成了下列三种形式的拾蛋器。竹制简易拾蛋器:(图1)找一截竹筒,直径比所要捡拾的蛋大1—1.5厘米为好,一般取直径为5—
Egg duck eggs, all people love to eat, but to collect scattered duck eggs one by one to collect, but not a relaxed and pleasant work. PENG Cai-yan, our school's uncle is the public family to raise duck private households, she saw the uncle from the duck shed every day to retrieve 150 to 160 duck, the older people, bent over arch back hand picking eggs, labor-intensive, Efficiency is not high, very hard. She made an egg picker for her uncle. This Egg Yolk won the second prize at the Second National Youth Science Invention Contest and Science Symposium in 1984. With the egg picker, the picker can stand and work, but also to improve the efficiency of picking up eggs, so the professional farming poultry favorite. Our science and technology group listened to the opinions of several duck raising professional households, and improved the egg picker invented by PENG Cai-yan and made the following three types of egg picker. Bamboo simple egg picker: (Figure 1) Find a section of bamboo, the diameter of the egg to be picked up 1-1.5 cm larger is better, generally take a diameter of 5-
