玉米脱粒机的发展
According to statistics, since the 1980s, China has begun to purchase a batch of advanced 玉米打谷机 from abroad. From the hand-operated 玉米打谷机 to electric corn thresher, farmers gradually relieve from the heavy manual labor. In the end of 2014, there were more than 240 top agricultural machine manufacturers in China, and they sold more than 350,000 sets, corn sheller, annually. China’s agricultural development constantly tends to be mechanized, and the development and research of it has gradually been put on the agenda and has become the focus of China’s agricultural development.
从玉米脱粒机的诞生、发展到普及，是中国农业现代化的标志。由于中国国土辽阔，山区的气候条件、农艺要求和经济条件差异很大，因此玉米脱粒机的使用非常广泛。
The annual harvest season is a busy time. Many farmers began buying 玉米打谷机 in advance, referring to its band, price and the technical parameter.
However, we can’t just look at the appearance to judge the quality of the machine, and the internal fittings are the most important. Thus, good thresher must be practical. Taizy Machinery specializes in agricultural equipment for more than 10 years, regarding designing machines, we consider both aesthetics and practicality. Our corn thresher is not only efficient but also designed with good looking.
As we all know, machine many occur some problems when operation. The biggest problem is that corn kernels can not be threshed fully. Today I will introduce some common problems and suggestions for you.
1. 一些玉米籽仍留在玉米棒上
reason:
(1). operator places too much corns into machine or the it is not uniform to put corn into machine.
(2). The threshing gap between the groove and the concave plate is too large.
(3). The rotation speed of the drum is too low;
(4). The corn is too moist.
解决方案
(1). reduce the amount of feed, even feeding.
(2). Correctly adjust the threshing gap, and replace the worn parts in time.
(3). The pulley of the power 玉米打谷机 should match the pulley of the thresher. If the pulley is slippery, adjust the tensioner to tighten the belt.
(4). the straw too wet food should be properly ventilated, dried and then threshed.
2. 清洁率 玉米打谷机 脱粒率低。
原因：
(1). 气流不足导致皮带打滑，导致风扇转速未达到指标。
(2). 风扇皮带轮螺丝松动，形成空转，风扇无法正常使用。
(3). 脱粒鼓中有太多稻草。
解决方案：
(1). 检查风扇皮带的张紧度，如果张紧轮过松，正确调整张紧器并将皮带调整到合适的程度；如果风扇皮带轮的固定螺丝松动，拧紧它。
(2). 减少喂入玉米的量或调整喂入间隙。
