The utility model discloses a set up the blend stop of multichannel area brush on the screen cloth, can block the gliding speed of stone, can also make things convenient for the jujube benevolence to slide fast simultaneously, realize the reposition of redundant personnel to stone and jujube benevolence.

Drawings

Fig. 1 is a schematic structural diagram of the present invention.

Wherein: 1. the fruit stone screening machine comprises a dustpan type screen, 2 parts of a machine shell, 3 parts of a screen plate, 4 parts of a fruit core discharge port, 5 parts of a date seed discharge port, 6 parts of a filter screen, 7 parts of a baffle, 8 parts of an air cylinder and 9 parts of a barrier strip.

Detailed Description

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

A screen of a swinging type screening machine for processing spina date seeds is shown in a figure 1, and comprises a dustpan type screen 1, wherein the dustpan type screen is arranged above a shell 2 in an inclined mode, and a screen plate 3 is arranged at the bottom of the dustpan type screen and used for blanking smaller kernel particles; the lower end of the dustpan type screen mesh 1 is provided with a discharge hole for the fruit pits and the jujube kernels to flow out.
