Abstract
The utility model discloses a grader with a cylindrical flow guiding cylinder. According to the grader, a flow guiding body in a flow guiding section, which is cone-shaped in the prior art, is changed to be column casing-shaped, and the surface of a column is used for guiding flow, so that air flow containing dust entering from an air inlet can rise in a straight line along an annular space formed by the flow guiding cylinder and a shell, and does not turn and reverse in midway. The dust-containing air flow rising in a straight line enters into a grading wheel uniformly, so that the lower section of the grading wheel can be prevented from being impacted by materials, therefore, the abrasion loss of the upper and lower parts of the blade of the grading wheel is the same, and the service life of the grading wheel is prolonged greatly.
Description
Technical field
The utility model relates to a kind of grader, particularly the grader housing.
Background technology
Existing grader is shown in Figure of description 1, and its diversion section is a conically shaped.Conical surface water conservancy diversion, make the dust-contained airflow major part of coming in rush at grader grading wheel base plate central authorities by air inlet, move to bottom edge along the base plate lower surface then, folding turn 90 degrees up again, make grading wheel blade bottom near a bit of rapid wearing of base plate, shorten the service life of grading wheel greatly.Can't satisfy needs of society.
Summary of the invention
The purpose of this utility model is, at the deficiency of above technology, innovates improvement by the structure to diversion section, and a kind of prolongation grading wheel service life, the grader that classification efficiency is higher are provided.
The technical solution of the utility model is: a kind of guide shell is columned grader, comprises grading wheel 1, guide shell 2, air inlet 3, housing 4 and discharging opening, it is characterized in that: being shaped as of its guide shell 2 is cylindrical.
Effect of the present utility model:
This grader is that columniform benefit is with the shaped design of the guide shell of charging aperture: the dust-contained airflow of coming in from air inlet rises the commutation of not turning midway along the annular space straight line that guide shell and housing form.The dust-contained airflow that straight line rises evenly enters grading wheel, avoids the grading wheel hypomere to avoid material impacting, thus grading wheel blade wear extent uniformity up and down, and prolong the service life of grading wheel greatly.
Description of drawings
The utility model can illustrate in conjunction with the embodiments.
Fig. 1 is the structure chart of conical surface water conservancy diversion grader general in the industry;
Fig. 2 is an example structure figure of the present utility model.
1 is that grading wheel, 2 is that guide shell, 3 is that air inlet, 4 is housing among the figure.
The specific embodiment
Referring to Fig. 1, the specific embodiment of the present utility model is: a kind of guide shell is columned grader, comprises grading wheel 1, guide shell 2, air inlet 3, housing 4 and discharging opening, and being shaped as of guide shell 2 is cylindrical.It is to make the shape of the baffle in the diversion section into column casing by existing awl tube, and the cylinder water conservancy diversion makes dust-contained airflow that air inlet comes in to rise the commutation of not turning midway along the annular space straight line that guide shell and housing form.The dust-contained airflow that straight line rises evenly enters grading wheel, avoids the grading wheel hypomere to avoid material impacting, thus grading wheel blade wear extent uniformity up and down, and prolong the service life of grading wheel greatly.Through on probation, the utility model reaches goal of the invention fully.
Claims (1)
1. a guide shell is columned grader, comprises grading wheel (1), guide shell (2), air inlet (3), housing (4) and discharging opening, and it is characterized in that: being shaped as of its guide shell (2) is cylindrical.
