高州县石鼓公社低坡大队林场,创造了一种营养磗育苗的联合机,可一次完成切磗、打孔、播种三个工序,效率比手工提高20倍。机件原理简单,制作容易。现介绍如下:一、构造:(如图)在木框架上装上三道工序的机构。打孔机是由圆木和一排排的小稜柱级成。播种机是由一枝圆形竹筒(两端有节),中间开孔而成,并设有装孔口及塞,以备装入种子及封口。切磗器是用方木锯缝插上切刀而成。切刀与地面成50—60度角。打孔器与播种器是可转动的,两者用链带和齿轮连系起来,转数相同。在前进中,打孔器稜柱与播种器播种孔在同一直线上,而切磗器
Gaozhou Shek Kwu Commune low slope brigade forest farm, to create a joint nutrition nursery seedlings, can be completed at one time, drilling, sowing three processes, the efficiency of 20 times more than the manual. Mechanical principle is simple, easy to make. Are introduced as follows: First, the structure: (Figure) installed in the wooden frame on the three processes of the agency. Punch is made of round wood and small rows of rows of prisms. The seeder is made of a round bamboo tube (with two ends) with a hole in the middle and a hole and plug for mounting seeds and seals. Cutter is cut with a wooden saw cut into the knife. Cutter and the ground into a 50-60 degree angle. Punch and seeder is rotatable, both linked with the chain and gear, the same number of revolutions. In progress, the puncher’s prongs are on the same straight line as the planter sowing holes, while the cutters are cut
