Pebble removing device for flour production

Abstract

The invention discloses a pebble removing device for flour production. The pebble removing device comprises a shell and a mounting box, wherein supporting legs are welded to four corners of the bottomand the mounting box is welded to one side of the shell. A receiving hopper and a charging hopper are separately locked and welded to the top ends of the mounting box and the shell, a vibratory screening mechanism and a secondary screening mechanism are separately mounted in the shell and the mounting box, the vibratory screening mechanism comprises a sieve plate, one end of which is slidably connected to the inner wall of the shell, fixed blocks I are welded to two ends of the side, close to the sieve plate, of the shell, a same vibrating spring I is welded to the side, opposite to the sieveplate, of each fixed block I, a material conveying port is formed in one side, close to the other end of the sieve plate, of the shell, and a fixed block II is welded to the inner wall of one side ofthe material conveying port. The pebble removing device can screen wheat effectively by means of the arranged vibratory screening mechanism and secondary screening mechanism, and wheat will fall offfrom the first screening mechanism and the second screening mechanism, so that relatively large impurities such as pebbles can be removed effectively.

Description

technical field [0001] The invention relates to the technical field of flour production, in particular to a stone removing device for flour production. Background technique [0002] Flour is a powder made from wheat. According to the protein content in flour, it can be divided into high-gluten flour, medium-gluten flour, low-gluten flour and gluten-free flour. It is the staple food in most parts of northern my country. There are many varieties of food made from flour, with a variety of patterns and different flavors. [0003] During the harvesting process of wheat, some larger debris such as stones are often mixed. In order to ensure the quality of flour, before the wheat is processed into flour, these larger debris need to be separated from the wheat, and then need to use Screening device. However, most of the traditional screening devices are relatively simple in structure, and the screening method is relatively simple, and the screening effect is relatively general, so...
