我们有一台浙江湖州4BL—1型半喂入联合收割机,但在收早稻时发现收割损失超过规定的3%。经过检查,主要由于我们收割的早稻产量高,禾秆粗大、穗长,因而在侧板槽、水平输送链和水平输送链与夹持输送链交接处谷粒散失严重。针对上述情况我们作了以下改进:1.在原弯槽的基础上加深挡禾槽,槽的始端加深为220毫米。这样禾穗在输送中,全部在槽内滑行,不被铁板刮脱掉谷粒。改装时(见图1、
We have a 4W-1 semi-fed combine harvester in Huzhou, Zhejiang Province, but we found the harvest loss exceeded the stipulated 3% when harvesting early rice. After the inspection, mainly due to our high yield of early rice harvest, straw stalks, spike length, so in the side slot, horizontal conveyor chain and horizontal conveyor chain and gripping conveyor chain junction grain loss seriously. In view of the above situation, we made the following improvements: 1. On the basis of the original curved slot to deepen the block Wo groove, the beginning of the deepening groove is 220 mm. This Wo spike in the transport, all gliding in the tank, not by the iron scraping remnants of grain. Modified (see Figure 1,
