早期备耕生产中,传统的木耢子由于后面拖带的圆木易上下跳动,对明垡多、冰茬厚的地块的耢地有一定困难。解决的办法是将木耢子改成重耢子。改装后的铁耢有三种:一是把从拖拉机上换下的旧大架子两个焊在一起,后面再带上一个链轨耢子,形成一个作业组;二是在割晒架的顺梁后面带上一个链轨耢子;三是用钢管圆木做撑杆,后面带链轨耢子,链轨耢子后面再带道轨或者联结器边梁。这三种耢子造价低,重量大,具有上下不易跳动、铁角碎土能力强和保墒好等特点。 In the early stage of tillage production, the traditional wooden razor clam could easily jump up and down due to the roundwoods towed behind. The solution is to change the wood clam into heavy clapper. There are three modified iron:: First, replace the old big tractor from the two welded together, followed by a chain rail 耢 son, the formation of a working group; Second, cut the sunning beam rack Behind the belt with a razor clam; third is to do with steel pipe strut rod, with a railing behind the raccoon, rail raccoon followed by rail or coupler side beams. These three kinds of prickly heat low cost, weight, with not easily up and down beating, iron angle broken soil strong and good soil moisture characteristics.
