Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings and specific embodiments.

As shown in fig. 1-3, the embodiment of the present invention includes a driving wheel 1, a roller 2, a screen 3, a casing (not shown), a covering plate (not marked, covering above the first partition and the second partition), the screen 3 and the roller 2 are located in the casing and driven by the driving wheel 1 to rotate, the screen 3 is arc-shaped, the roller 2 is located above the screen 3, the covering plate is located above the first end of the roller 2, the surface of the casing is provided with an impurity discharging outlet 7, and the impurity discharging outlet 7 corresponds to the first end of the roller 2.

The corn straw is fed along arrow K1, and cylinder 2 is rotatory (fig. 2) along arrow K3 for the corn straw moves along arrow K2, in order to slow down the translation rate of corn straw, and this embodiment still includes parallel arrangement and the middle first baffle 5, the second baffle 6 that set up the spaced, and first baffle 5, the second baffle 6 is located the first end of cylinder 2, and cylinder 2 passes first baffle 5, the second baffle 6, forms the structure that first baffle 5, the second baffle 6 encircle cylinder 2. The first partition plate 5 is close to the casing and is spaced from the casing, namely a separation chamber 41 is formed between the first partition plate 5 and the casing, a separation chamber 42 is formed between the second partition plate 6 and the first partition plate 5, and the impurity discharging outlet 7 corresponds to the separation chamber 41 between the first partition plate 5 and the casing. The lower side of the first clapboard 5 is provided with a first diversion channel 50, and the feeding side of the second clapboard 6 is provided with a second diversion channel 60. Inside the casing, a horizontal step 30 is provided at a position of the screen 3 corresponding to the trash outlet 7, and the horizontal step 30 corresponds to the bottom of the trash outlet 7 (fig. 3).
