Specific embodiment
As shown in figs. 1 to 6, a kind of adjustable trash rack, including chassis body, the chassis body include interconnected
Top beam 1, vertical beam 2, bottom beam 3 and fixed grizzly bar 5, further include several movable grizzly bars 8, and movable grizzly bar 8 includes the centre of equal length
Steel band 81 and round tube 82, two round tubes 82 are respectively fixedly connected in long side surface corresponding with the cross section short side of intermediate steel band 81
On, and be aligned along the length direction of intermediate steel band 81；
It is provided on the top beam 1 of the chassis body and wears a hole 1a with movable 8 shape of grizzly bar corresponding first, first wears item
Hole 1a is arranged in accordingly on the position that two phases are stated between fixed grizzly bar 5,3 upper surface of the bottom beam setting of the chassis body
There is positioning pin 7, it is corresponding that a hole 1a is worn in the position of positioning pin 7 with first in the vertical direction；
Positioning pin 7 is cylindrical positioning pins, and the outer diameter of positioning pin 7 is consistent with the internal diameter of round tube 82, and round tube 82 can be inserted
Interior, the center of two positioning pins 7 of same group is away from the center with two round tubes 82 on any one movable grizzly bar 8 away from consistent；It is fixed
The top of position pin 7 is provided with ramp down angle, and the axis setting of positioning pin 7 described in the long edge at ramp down angle can guarantee movable grizzly bar 8
It is successfully inserted on positioning pin.It is several activity grizzly bars 8 lower end through described first wear a hole 1a after be located by connecting to positioning pin
On 7 and it is connected on bottom beam 3.
As shown in Figure 2,3, 4, the chassis body further includes central sill 4, and 4 both ends of central sill are welded on vertical beam 2, fixed railing
Item 5 is divided into upper and lower two parts, and upper fixed 5 both ends of grizzly bar, which are respectively welded, is connected to the top beam 1 and central sill 4 and equidistant cloth
It sets, lower 5 both ends of part fixed railing item, which are respectively welded, to be connected on the central sill 4 and the bottom beam 3 and be equally spaced.Central sill 4
The intensity of trash rack can be increased, can further fix movable grizzly bar 8.
It is provided with several second on central sill 4 and wears a hole 4a, second, which wears a position of hole 4a and first, wears mono- a pair of a hole 1a
It answers；First, which wears a hole 1a and second, wears and is provided with the consistent extending sleeve 6 of inner hole section, several extending sleeves 6 below a hole 4a
