扣种大豆等距点播机工农-12手扶拖拉机扣种大豆等距点播机作业时,一去破茬,回来点播、掏墒,一次可播种三条垅。用四速中油门作业时,每天可扣种30～32亩,能代替八匹马、十八个人工,提高工效五到六倍。更换排种轮可穴播高粱、宽幅条播谷子,每天可播种45～60亩。主要结构和参数该机主要由等距点播装置和翻耕犁铧两部分组成。点播装置主要由牵引方梁、起落机构和点播车组成。翻耕犁铧是用随车带的弯勾和培土铧。点播车由排种器、四连杆仿形机构和引导轮组成(见图1)。排种器主要由排种轮2、种子箱7、护种
Isochronous Sowing Soybean Offset Workers-Peasants -12 Walking Tractor Sowing Isometric Soybean On-boarding Job, go to stubble, back on-demand, dig soil moisture, once can sow three 垅. With four-speed throttle operation, the buckle per day can buckle 30 to 32 acres, can replace eight horses, eighteen artificial, improve work efficiency five to six times. Replacement of seed wheels can be punched sorghum, broad-band corn, daily sowing 45 ~ 60 acres. The main structure and parameters This machine is mainly composed of isocasting on-demand devices and tillage plowshare two parts. On-demand devices mainly by the beam beam, landing gear and on-demand car components. Plowshare Plowshare is with the truck with hook and Pei Hua land. The on-demand car consists of a seed metering device, a four-bar contouring mechanism and a guide wheel (see Figure 1). The seed metering device mainly consists of a seed metering wheel 2, a seed box 7 and a seed guard
