Description

Technical Field

[0001] The utility model relates to the technical field of wheat processing, in particular to a wheat raw material screening device. Background Art

[0002] Wheat is a general term for plants of the genus Triticeae, with common wheat as the representative species. It is a grass plant and a cereal crop widely grown around the world. The caryopsis of wheat is one of the staple foods of humans. After being ground into flour, it can be used to make bread, steamed buns, biscuits, noodles and other foods. After fermentation, it can be made into beer, alcohol, liquor, or biomass fuel.

[0003] Most of the existing wheat usually needs to be screened before processing to ensure that the remaining granular impurities and impurities such as bran in the wheat can be cleaned, thereby ensuring the taste of the wheat flour. When most of the existing wheat screening devices are in use, they can often only vibrate and screen the granular impurities in the wheat, but light impurities such as bran in the wheat need to be processed twice. Although this method can effectively clean the wheat, it increases the process and efficiency of the wheat screening process, thereby reducing the overall efficiency of the wheat screening operation. Utility Model Content

[0012] Preferably, a spiral ring body is fixedly mounted on the surface of the sealing cover, a screw groove is provided on the surface of the collecting cover, and the sealing cover is threadedly mounted on the screw groove of the collecting cover through the spiral ring body.

[0013] Compared with the prior art, the beneficial effects of the present invention are:

[0014] (1) The wheat raw material screening device can prevent the bran from falling into the inner side of the collecting cover due to the funnel shape of the collecting cover, and the inclined shape of the supporting base will be biased toward the movable block, thereby ensuring that the impurities are automatically guided and collected after being collected at the supporting base. This method ensures that the wheat raw materials have the effect of screening and separating multiple impurities when screening, and ensures that the wheat raw materials have the effect of synchronously separating light impurities when screening granular impurities, thereby improving the disadvantage of the traditional wheat raw material screening that requires the distribution operation of granular impurities and bran, thereby improving the efficiency of the wheat raw material screening operation.

[0025] See also Figure 1-4 The utility model provides a technical solution: a wheat raw material screening device, including a supporting base 1, a vibrating screen body 2 is arranged above the supporting base 1, a collecting cover 3 is arranged on the surface of the vibrating screen body 2, a sealing cover 6 is arranged on the surface of the collecting cover 3, a spiral ring body 14 is fixedly installed on the surface of the sealing cover 6, a screw groove 15 is opened on the surface of the collecting cover 3, and the sealing cover 6 is threadedly installed with the screw groove 15 on the collecting cover 3 through the spiral ring body 14. The function of the sealing cover 6 is to seal the collecting cover 3, so that the wheat raw material has a good dust-proof effect when it reaches the vibrating screen body 2 for screening.

[0026] Furthermore, a positioning bolt 9 is opened on the inner side of the vibrating screen body 2, and a positioning groove 8 is fixedly installed on the surface of the collecting cover 3. The collecting cover 3 is threadedly installed with the positioning bolt 9 on the vibrating screen body 2 through the positioning groove 8. The collection cover 3 and the vibrating screen body 2 have a disassembly effect, which ensures that the inside of the vibrating screen body 2 has a convenient cleaning effect.

[0027] Furthermore, a filter screen 4 is provided on the inner side of the vibrating screen body 2, and an auxiliary handle 10 is fixedly installed on the surface of the filter screen 4. The function of the filter screen 4 is to fill the wheat and then put it into the vibrating screen body 2 for vibration screening, so as to facilitate the subsequent cleaning of the screened wheat.

[0028] Furthermore, a limiting ring 11 is fixedly installed on the inner side of the vibrating screen body 2. The limiting ring 11 is arc-shaped. The function of the limiting ring 11 is to support the filter screen 4 when it is placed in the vibrating screen body 2, and the arc shape of the limiting ring 11 can reduce the effect of impurities remaining on its surface.

[0029] Furthermore, a guide groove 5 is provided on the inner side of the collecting hood 3, a fan body 12 is fixedly installed on the surface of the supporting base 1, a movable block 13 is provided on the surface of the supporting base 1, the shape of the surface of the supporting base 1 is inclined, the fan body 12 is located below the filter screen 4, the filter screen 4 is located below the guide groove 5 on the collecting hood 3, and the shape of the collecting hood 3 is funnel-shaped.

[0030] The fan body 12 is blown upward by the wind, and the sand and gravel in the wheat will fall off to the inner side of the support base 1 through the filter screen 4 when the wheat raw materials in the filter screen 4 are screened, and the bran in the wheat material will be blown upward by the wind of the fan body 12. After the bran passes through the guide groove 5, the funnel shape of the collecting cover 3 can prevent the bran from being affected by the wind and falling on the inner side of the collecting cover 3 for collection. The inclined shape of the support base 1 will deviate toward the movable block 13, thereby ensuring that the impurities are automatically guided and collected after reaching the support base 1 for collection. This method ensures that the wheat raw materials have the effect of screening and separating multiple impurities when screening, and ensures that the wheat raw materials have the effect of synchronous separation of light impurities when screening granular impurities, thereby improving the disadvantage of the traditional wheat raw material screening that requires the distribution operation of granular impurities and bran, thereby improving the efficiency of the wheat raw material screening operation.

[0031] Working principle: A wheat raw material screening device, when the vibrating screen body 2 is used to vibrate and screen the wheat raw materials in the filter screen 4, the fan body 12 will work synchronously. The fan body 12 is blown upward due to the wind force, and when the wheat raw materials inside the filter screen 4 are screened, the sand and gravel in the wheat will fall off to the inner side of the support base 1 through the filter screen 4, and the bran in the wheat material will be blown upward with the wind force of the fan body 12. When the bran passes through the guide groove 5, the funnel shape of the collection cover 3 can prevent the bran from being affected by the wind and falling on the inner side of the collection cover 3 for collection.

[0032] The embodiments of the present invention are described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Various changes can be made within the scope of knowledge possessed by ordinary technicians in the technical field without departing from the purpose of the present invention.
