<p>A combine harvester threshing in combing manner. A blade-type reaping device (1) is mounted at the front end of a frame, a threshing device (2) with an upper drum and a lower drum is mounted on the frame at the rear of the blade-type reaping device, a vibrating sieve and a grain tank (5) are disposed at the lower side of the threshing device with an upper drum and a lower drum, a lower threshing drum (32) is dynamically connected to the vibrating sieve and the grain tank by an eccentric gear, an upper threshing drum (31) is dynamically connected to the blade-type reaping device, and a rotary-type spiral-drum straw breaker (3) is mounted on the frame at the lower sides of the vibrating sieve and the grain tank. A rear threshing drum (4) is mounted on the frame at the rear end of the threshing device with an upper drum and a lower drum, a vibrating sieve and a grain tank are disposed at the lower side of the rear threshing drum, a suction outlet is disposed at each of the bottoms of the vibrating sieve and the grain tank, the suction outlet is communicated, by an suction outlet pipe, with a multi-cylinder separator (6) for separating grains from debris, so that the grains and the debris enter the multi-cylinder separator for separating grains from debris and are separated, the grains are bagged at a grain exit (55) and the debris is blown out by a fan (53).</p> |
