Specific implementation mode
The utility model is described in further detail in the following with reference to the drawings and specific embodiments.
As shown in Figures 1 to 3, a kind of trash rack being convenient to clean, including fence 1 and the grapple 2 set on 1 upstream side of fence,
The top of the grapple 2 is connect with power traction mechanism output end, and 2 side of the grapple is slidably connected by pulley 3 and sliding rail 4,
The sliding rail 4 is fixed on the supporting rack 1.1 of 1 side of fence, and hydraulic pressure sensor 5, the grid are equipped on support frame as described above 1.1
Sieve 6 is partly also equipped on column 1.
Preferably, the grapple 2 includes vertically movable axis 2.1,2.1 top of the vertically movable axis and power traction mechanism
Output end connects, and 2.1 side of vertically movable axis is slidably connected by pulley 3 and sliding rail 4,2.1 bottom of vertically movable axis
Portion is articulated and connected with the first rotary shaft 2.2.1 set on 2.2 one end of the first returning face plate, 2.2 other end of the first returning face plate with
The second rotary shaft 2.3.1 articulated connection set on 2.3 one end of the second returning face plate, the first rotary shaft 2.2.1 input terminals with set
Axis connection, input terminal and another electric rotating machine of the second rotary shaft 2.3.1 are exported in the electric rotating machine on supporting rack 1.1
Export axis connection.After designing in this way, vertically movable axis 2.1 can be pulled to move up by power traction mechanism, so that entirely
Grapple 2 moves up, to pull sundries out；And the first rotary shaft 2.2.1 can drive the first returning face plate 2.2 to overturn, the second rotation
Axis 2.3.1 can drive the second returning face plate 2.3 to overturn, and can be incited somebody to action by the overturning of the first returning face plate 2.2 and the second returning face plate 2.3
