Vertical mechanical stone mill

Abstract

The invention provides a vertical mechanical stone mill, consisting of a fixed bracket, a lower grinding disc, an upper grinding disc, and a power transmission shaft which is arranged at the central hole of the lower grinding disc and the upper grinding disc; one end of the power transmission shaft is connected with a power mechanism; the upper grinding disc is provided with a grain inlet; the upper grinding disc is fixedly connected with the fixed bracket; the top end of the power transmission shaft is provided with an adjusting nut and the bottom end thereof is provided with a supporting shoulder; the power transmission shaft is fixedly connected with the lower grinding disc; the clearance between the upper grinding disc and the lower grinding disc is more than or equal to 0mm; a bearing is arranged between the power transmission shaft and the central hole of the upper grinding disc; and the lower end of the bearing is provided with an adjusting washer. The upper grinding disc and the lower grinding disc have a certain clearance and are not contacted with each other; no matter the change of the feeding quantity of the grains, the direct contact of the upper grinding tooth and the lower grinding tooth is not generated, the clearance is not increased under the action of the grains, the defect of the quick abrasion of the grinding tooth is thoroughly solved, the service life of the grinding tooth is prolonged, the repairing time is reduced, the production efficiency and the one-step powder yield of the flour are improved, the power dissipation is reduced, the working noise is reduced, and the energy resource is saved.

Description

Technical field: [0001] The invention relates to the field of daily necessities, in particular to a vertical mechanical stone mill. Background technique: [0002] In the process of traditional stone milling, the upper millstone runs and the lower millstone is fixed. When the speed increases, the centrifugal force generated by the upper millstone is large, which is inconvenient and poor in safety when adding grain. At the same time, the traditional stone mill relies on the gravity pressure of the upper millstone. On the lower grinding disc, the grinding teeth directly contact the friction grinding powder, which makes the grinding teeth wear quickly, especially when no grain is added, and a large amount of stone powder is mixed into the flour, which affects the quality of the flour. In addition, because the weight of the upper grinding disc is Limited, during the milling process, due to the effect of grain, the upper millstone will jump up and down, resulting in impact, high n...
