Detailed Description
The following description will further describe embodiments of the present invention with reference to the accompanying drawings and examples. The following examples are only for illustrating the technical solutions of the present invention more clearly, and the protection scope of the present invention is not limited thereby.
As shown in fig. 1-3, drum-type sand and stone screening machine, including frame 1, driving motor 9, the rotatable cylinder 2 that is used for sieving husky that is equipped with in frame 1, the rotatable returning face plate 7 that is equipped with of axis of rotation 8 is passed through to one end in frame 1, driving motor 9 is fixed to be located on the returning face plate 7, driving motor 9's drive shaft is connected with the connection pad 12 of 2 tip of cylinder, the 2 other end of cylinder is equipped with the feed inlet 4 of seting up feedstock channel, the rotatable dwang 5 that is equipped with on the feed inlet 4, the fixed pneumatic cylinder 3 that is used for making 2 luffing motion of cylinder that is equipped with in frame 1, 5 movable groove 51 that runs through the dwang has been seted up on the dwang, wear to be equipped with bolt 6 and bolt 6 is located movable groove 51 between the extension bar of pneumatic cylinder 3 and the dwang 5, bolt 6 is locked and is equipped with the nut that is used for preventing the extension bar of pneumatic cylinder 3 and dwang 5 and breaks away from.
In order to conveniently replace the rollers 2 with different models so as to screen gravels with different sizes, a rotating disc 10 is fixedly arranged on a driving shaft of the driving motor 9, and the rotating disc 10 is locked on a connecting disc 12 at the end part of the roller 2 through a bolt 11.
In order to facilitate replacement of the roller 2, the rotating disc 10 and the connecting disc 12 at the end of the roller 2 are aligned neatly and better, the rotating disc 10 is provided with a square groove 101, and the connecting disc 12 at the end of the roller 2 is fixedly provided with a square block which can be clamped into the square groove 101.
The working principle is as follows:
when will sifting the grit, not hard up nut makes dwang 5 articulate on bolt 6, then the hydraulic stem of pneumatic cylinder 3 drops to the most suitable height that makes things convenient for the staff to fill out the grit, and the staff puts into the grit 2 back, rises to the most suitable height of sieve grit stone with the hydraulic stem of pneumatic cylinder 3, then lock nut, and driving motor 9 rotates again, drives cylinder 2 and rotates, and then carries out the screening of grit. When the screening is finished, the nut is loosened, the hydraulic rod of the hydraulic cylinder 3 descends to the lowest point, unqualified gravel in the roller 2 is automatically poured out, the operation is repeated again when the unqualified gravel is cleaned, the sand screening is continued, and the gravel screening by workers is greatly facilitated. When the grit of different specifications will be screened, as long as loosen bolt 10 on connection pad 12 and bolt 6 on the hydraulic stem of pneumatic cylinder 3, take off cylinder 2, then load onto the cylinder 2 of different specifications, can accomplish the change of cylinder 2, it is simple again convenient.
Having shown and described the basic principles and essential features of the invention and its advantages, it will be understood by those skilled in the art that the present invention is not limited by the embodiments described above, which are merely illustrative of the principles of the invention, but is susceptible to various changes and modifications without departing from the spirit and scope of the invention, all of which are intended to be covered by the appended claims and their equivalents.
