草坪根茎采集收获机气吸输送装置的设计
摘要
实验发现，在草坪跟根茎采集收获时，伴随着根茎尚有大量的泥土砂石被甩刀甩了上来。为了保证根茎采集收获的质量，必须在草坪根茎采集收获机上添加一个清选装置，即草坪根茎采集收获机的气吸输送装置。
草坪根茎采集收获机的气吸输送装置主要包括两个部分，一部分是贯流风机，它利用叶轮的旋转，在进风口处形成一个负压。从而使质量较轻的根茎被吸上来。而把质量较重的泥土，砂石留在了筛板上。第二个部分是振动筛。它主要是利用其自身的振动，把存在其上的颗粒较小的泥土、砂石从筛孔中漏到地面上。
本文主要对贯流风机的几何参数和运动参数进行了分析、研究和设计，确定了其传动方案，并对贯流风机的轴进行了设计计算及校核。选择并校核了轴承和键。同时对振动筛进行了研究设计，确定了其几何参数及筛孔的分布情况。最后对贯流风机及振动筛进行了装配和布置。

Abstract
Experiments show that, on the lawn with rhizomes collected at harvest time, accompanied by the root there are a lot of clay sand flail throw up. In order to ensure the rhizome acquisition harvest quality, must add a cleaning device in the lawn rhizome acquisition harvester, namely grass roots acquisition harvester pneumatic conveying device.
Lawn rhizome acquisition harvester pneumatic conveying device mainly consists of two parts, one part is a cross flow fan, which utilizes the impeller rotation, the formation of a negative pressure in the air inlet. So that the quality of the lighter roots are sucked up. The quality of the heavier mud, sand and gravel in the sieve plate. The second part is the vibration sieve. It is mainly the use of vibration of its own, the smaller grains on the clay, sand and gravel from the mesh of the leakage to the ground.
The geometric parameters and the movement parameters of the main flow fan on the penetration of research and design, analysis, the transmission scheme is determined, and the flow fan on the tubular shaft design calculation and checking. Selection and check of bearing and bond. At the same time of the vibrating screen is researched and designed, the distribution of the geometric parameters and the mesh was determined. At the end of the cross flow fan and vibration screen assembly and arrangement.
