为了在播种时能同时施肥,并保证施肥均匀,和便于调整施肥量,我们在СД-24行条播机上加设了带施肥杯的施肥箱。经过多次改进,已消除易堵、不匀及施肥量不准确等毛病。施肥箱的安装方法如下:施肥箱用木板制成,容量为0.1立方公尺,用支架固定在种子箱后,和种子箱并列,并用三根拉筋和种子箱固定在一起。在施肥前后侧板的下部,固定两块三公厘厚的薄角铁,24个排肥杯和左右两个调整施肥量的指度盘,都固定在这两块角铁上,如右图所示。施肥杯是仿照排种杯的构造翻砂制成的。施肥轴由排种方轴驱动,在排种方轴端部加一轴套,安上7个牙的链轮,在施肥轴上安10个牙的链轮,用链条传动。
In order to fertilize at the same time at planting, to ensure uniform fertilization and to facilitate the application of fertilizers, we applied a fertilizing tank with a fertilizer cup on the СД-24 line of seed drill. After many improvements, it has eliminated the problems of easy blocking, unevenness and inaccurate fertilization. The fertilizer box is installed as follows: The fertilizer box is made of wood and has a capacity of 0.1 cubic meter. After it is fixed in the seed box with the bracket, it is placed side by side with the seed box and fixed with the three seed boxes. Before and after fertilization in the lower part of the side panels, fixed two three-centimeter thick thin angle iron, 24 fertilizer cups and about two adjust the amount of fertilizer dial, are fixed in the two angle iron, as shown Show. Fertilizer cup is modeled after the construction of cup seedling made of sand. The fertilizing shaft is driven by a seeding square shaft. A sleeve is mounted on the end of the seeding square shaft, sprocket mounted on 7 teeth, and 10 tooth sprockets on the fertilizing shaft are driven by the chain.
