2BJM小麦精播机作为一种新型播种机已经走在了同类产品的前列,在使用中受到了广大农民朋友的欢迎。但是该机具是否就完美无缺了呢?带着这种想法,笔者走访了许多用户,从用户提出的要求中筛选出了4个问题,在此提出来,以便科研单位及厂家研究改进。 1.机架的刚度差 2BJM小麦精播机机架是由平行四连杆仿形机构和排种器支架连接而成,使用材料是50毫米×50毫米,40毫米×40毫米的角钢,连接点由两个螺栓紧固。使用中,当土质较硬或者土壤泥泞,阻力超过两个螺栓连接处角钢的承受力时,会使
2BJM wheat sowing machine as a new type of sowing machine has walked in the forefront of similar products, in use by the majority of farmers friends welcome. However, whether the equipment is perfect or not? With this idea, I visited many users, from the user’s request out of the four selected in this proposed, so that research institutes and manufacturers to improve. 1. Rigidity difference of 2BJM wheat precision broadcast machine rack is composed of parallel four-bar linkage mechanism and seed metering device bracket, the use of materials is 50 mm × 50 mm, 40 mm × 40 mm angle steel, connected Point fastened by two bolts. In use, when the soil is harder or the soil is muddy, the resistance exceeds the bearing capacity of the angle at the two bolted joints
