fig. 2 is a simplified exploded view of a side plate and a control plate of the fine screen of the present invention.

Detailed Description

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

In order to realize the purpose of comparatively thoroughly eliminating the grain that mildenes and rot, the utility model provides a fine screening sieve embodiment includes frame (not shown), the grain clearing device that mildenes and rot that fig. 1 shows, hopper 6, the grain clearing device that mildenes and rot includes the proportion platform, this proportion platform includes mesa 1, two curb plates 2, the moving direction (the direction that the arrow head is shown in fig. 1) of grain sets up respectively in the left and right sides of mesa 1 upper surface on two curb plates 2 along mesa 1, be equipped with the discharge port 21 that is used for discharging the grain that mildenes and rot on the curb plate 2, discharge port 21 corresponds with the region that the grain that mildenes and rot concentrates in the operation process. In the use, mesa 1 is making complicated reciprocating motion for grain moves along the arrow direction, and the granule that mildenes and rot moves, progressively concentrates towards the direction of curb plate, sets up discharge port 21 in the concentrated region of the granule that mildenes and rot and can even discharge the granule that mildenes and rot, prevents to mildenes and rot and grain and continues to mix together with normal grain, can improve screening quality.

In order to improve the screening quality, since the concentration region of the mold grains is distributed in a band shape along the inner wall of the side plate 2, it is preferable that a plurality of discharge ports 21 are provided in each side plate 2, and the plurality of discharge ports 21 are provided along the longitudinal direction of the side plate 2.

In order to collect the mildew grains intensively, a channel 40 which corresponds to the discharge port 21 and is used for collecting and conveying the mildew grains is also arranged on the outer side of the side plate 2, the channel 40 is connected with the table board 1, and the channel 40 and the table board 1 move simultaneously. The channel 40 is relatively simple to form, with side plates 2 on one side, a channel plate 4 on one side and a bottom plate 3 on the bottom, preferably with a fish-scale screen plate 3 on the bottom. The channel plate 4 outside the channel 40 is parallel to the side plate 2, and the end of the channel plate 4 is provided with an opening 41 for concentrated unloading of the mold grains.

In order to collect the mildewed granules, the present embodiment further comprises a hopper 6, the hopper 6 is fixed on the frame, and the upper end of the hopper 6 corresponds to the opening 41. If there is no channel, one hopper per discharge port is required.

In practical application, the presence or absence and the amount of the mildewed particles may be different, and in order to meet the requirement, the outer side of the side plate 2 of the embodiment can be further provided with a movable regulating plate 7, and the regulating plate 7 can completely or partially cover the discharge opening 21.
