[0006] Preferably, an air outlet is left between the bottom end of the blocking plate and the grate plate frame, the blocking plate is designed in an L-shape and is used to support a plurality of grate rods, and slots are symmetrically provided at both ends of the blocking plate.
[0007] Preferably, one end of a plurality of the grate rods away from the blocking plate is fixedly connected to a connecting plate, and the connecting plate is hinged to the grate plate frame.
[0008] Preferably, a side of the grate frame away from the blocking plate is provided with an avoidance groove, and a stopper is slidably connected to the inner wall of the avoidance groove, and the stopper is designed in a L-shaped shape.
[0009] Preferably, the interior of the insertion rod is hollow.
[0010] Preferably, the insertion rod and the slot are fixedly connected by bolts.
[0011] Compared with the prior art, the beneficial effects of the utility model are:
[0012] The utility model increases the ventilation effect of the grate plate by respectively opening bottom ventilation slots and side ventilation slots at the bottom and both sides of the grate plate frame and leaving air outlets between the blocking plate and the grate plate frame. In addition, a plurality of flippable grate rods are designed, and the grate rods are cylindrical in design to reduce blockage between materials and the grate rods. When blockage occurs between the grate rods, the grate plate is lifted up and the blockage is cleared by a plurality of scraping rods on the blocking plate. BRIEF DESCRIPTION OF THE DRAWINGS
