Rail, 7 idler wheels, 8 mounting bases, 9 motors, 10 crankshafts, 11 pull rods, 12 mounting plates.
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without making creative work
Every other embodiment obtained, fall within the protection scope of the utility model.
Fig. 1-3 is please referred to, the utility model provides a kind of technical solution: a kind of biomass fuel pellet processing screening dress
It sets, including board 1, bottom plate 2 and sieve nest 3, the upper surface of the board 1 is equipped with several idler wheels 7, the bottom by bracket
The downside of plate 2 is equipped with guide rail 6, and the upside of the idler wheel 7 and the groove of guide rail 6 are clamped, and the left side of the bottom plate 2 passes through bracket
It is hinged with pull rod 11, the left end of the pull rod 11 and the axle journal of crankshaft 10 are hinged, and the lower end of the crankshaft 10 and the rotation of board 1 connect
It connects, the sieve nest 3 includes box body 31, and the inner cavity of the box body 31 is fixedly connected with sieve plate 32, and the upside of the board 1 is hinged with
Hydraulic cylinder 4, the push rod of the hydraulic cylinder 4 and the left end bottom of box body 31 are hinged.
Specifically, the upper surface of the board 1 is fixedly connected with mounting base 8, the mounting base 8 is inverted U shape, the installation
The upside of seat 8 is equipped with motor 9, and the output end of the motor 9 is fixedly connected with the upper end of crankshaft 10, and motor 9 drives crankshaft 10
Rotation, crankshaft 10 drive bottom plate 2 to move reciprocatingly by pull rod 11.
Specifically, being welded with mounting plate 12 on the right side of the upper surface of the bottom plate 2, the right end bottom of the sieve nest 3 is welded with
Trunnion 5 is installed, hinged by pin shaft between the installation trunnion 5 and mounting plate 12, the right end of sieve nest 3 is hinged, and left end is by hydraulic
Cylinder 4 supports, the flexible inclination angle that can adjust sieve nest 3 of hydraulic cylinder 4.
Specifically, the left end closing right end of the box body 31 opens wide, the spacing of the sieve plate 32 to 31 bottom of box body is 10
~15cm, short grained biological particles pass through sieve plate 32 and fall on the bottom plate 2 of box body 31 during vibration.
Specifically, the right end of the box body 31 is welded with discharge port 33, the left end of the discharge port 33 is connect with sieve plate 32,
