Abstract
The invention discloses a novel anti-blocking device applied to a protective cropping system. According to the novel anti-blocking device, a rack is connected with a tractor through a three-point suspension device; the power output shaft of the tractor is connected with the input end of a gearbox through a universal coupler; two output ends of the gearbox respectively transmit power to an obliquely arranged circular disc and a Roots blower through chain transmission and belt transmission; a press wheel drives a seed sowing plate to rotate through chain transmission; an air-suction seed sowing device realizes seed distribution; seed sowing pipes are connected with a seed injecting device. When a unit goes forwards, the obliquely arranged circular disc furrows a furrow on the no-tillage earth surface, so that straws are cut and soil is loosened at the same time; the seed injecting device can mix compressed air provided by the Roots blower and seeds sown by the air-suction seed sowing device, and the seeds are injected into loosened soil at certain speed and are compacted by the press wheel, so that the sowing work can be finished. According to the device, the sowing work without a furrow opener can be realized, the probability of straw blockage in the operation of a no-tillage seed sowing machine is lowered, and the passing capacity of the seed sowing machine is improved.
