- the height of the thickness baffle plate 7 is adjusted first. If it is necessary to adjust the thickness of the lime powder, the height of the thickness baffle plate 7 is adjusted first, so that the worker pulls the frame 1 The force does not change much, and if the speed ratio is not adjusted by adjusting the thickness of the baffle plate 7, the rotation speed of the worker acting on the conveying roller 5 at the same walking speed is increased, and it is necessary to increase the pulling force of the worker and increase the labor of the worker.
- the strength is therefore in the design range. If the lime powder is increased, the height of the lime powder baffle is preferentially adjusted, which saves the worker's strength. Of course, the height of the lime powder retaining plate cannot be increased without limit. At least it is lower than the height of the discharge port of the hopper 3. Therefore, if the height of the baffle plate is adjusted to the maximum limit, if the thickness of the lime powder is to be increased, the speed ratio can be adjusted.
- the lime powder is provided with a width baffle plate 8 and a thickness baffle plate 7 to ensure uniformity of lime powder laying. Of course, in addition to adjusting the thickness of the lime powder by using the dial 16, it is also possible to adjust the power shaft by measuring the thickness of the lime powder after laying.
