Background

In the technical field of flour processing, a flour mill is an important processing device, a grinding roller is a main working component of the flour mill, the hardness of the surface material and the surface structure of the grinding roller have great influence on the production benefit of the flour milling industry, when the flour mill is just used, the grinding teeth are sharp, the yield is high, the power consumption is low, after a new roller is used for a certain time, along with the dulling of the grinding teeth, the yield is reduced, the power consumption is increased, the crushing and scraping effects are reduced, the powder containing rate of drum skin is increased, the flour yield is reduced, in addition, the hardness of the roller surface of a smooth roller is much lower than that of a nonmetal grinding material, the service life is relatively short, the grinding roller is frequently replaced, the grinding roller of the traditional grain flour mill is a grinding roller, the load of the grinding roller is large, the service life of the grinding.

SUMMERY OF THE UTILITY MODEL

The utility model aims at solving the defects existing in the prior art and providing a grain grinding roller of a grain grinding machine.

In order to achieve the above purpose, the utility model adopts the following technical scheme:

the utility model provides a grain milling machine grinding roller, includes that two are located same water flat line's axis of rotation, two the card strip that the equidistance distributes is all welded to the axis of rotation outer wall, and the axis of rotation outer wall all cup joints the mill that the inner wall opened the draw-in groove and presses the sleeve, and grinds and press the sleeve outer wall welding to have the mill that the equidistance distributes and press the granule, two external screw thread tooth has all been opened to axis of rotation both ends outer wall, and the equal spiro union of external screw thread tooth has the internal thread fixed block, axis of rotation one end welding has the rotation wheel, and two are located same water flat line's axis of rotation and have welded driving gear and driven gear in proper order with the one end, two the bearing.

Preferably, the distance between the grinding and pressing sleeves inserted into the two rotating shafts forms a grinding and pressing groove.

Preferably, the center of the outer wall of one side of each of the two connecting rods is welded with a fixing rod perpendicular to the connecting rod.

Preferably, the driving gear and the driven gear are meshed with each other.

Preferably, the number of the clamping strips is equal to that of the clamping grooves, and the clamping strips are connected with the clamping grooves in a sliding mode.

Preferably, the grinding roller of the grain mill is provided with a plurality of grinding pressure sleeves with equal inner diameters and unequal outer diameters.

The utility model has the advantages that:

1. use motor belt strip to rotate an axis of rotation through rotating the wheel, then all rotate to the inboard through driving gear and driven gear and grind and press grain, roll grain through two axis of rotation and not only be of value to the quality that improves grain and grind out, and improved the life of grinding roller.

2. The grinding and pressing sleeve is sleeved and connected with the rotating shaft, so that the size of the grinding and pressing sleeve is convenient to replace and used for grinding and pressing powder of different grains, the grinding roller only needs to be replaced when damaged and replaced, and the cost is saved.
