DETAILED DESCRIPTION

[0019] like Figure 1-6As shown: A folding vibration grate for a biomass boiler, including a furnace 1, an ash discharge port 2 is opened at the bottom of the front side wall of the furnace 1, and the inner top wall of the ash discharge port 2 is rotatably connected to the furnace door 3. Guide holes 4 are opened in the middle of the front and rear inner walls of the furnace 1, and the guide holes 4 are located above the ash discharge port 2. There are several grates 5 between the two guide holes 4. The grates 5 are arranged on the left and right, and the adjacent grates 5 are rotatably connected. The middle of the front and rear ends of the grates 5 are rotatably connected with pulleys 6, which are located in the guide holes 4. The pulleys 6 are slidably matched with the guide holes 4. Slide holes 8 are opened on the left side of the front and rear side walls of the furnace 1, and the slide holes 8 are located on the left side of the guide holes 4. The leftmost grate 5 The left ends of the front and rear ends are fixedly connected to the sliding rod 9, which is inserted into the sliding hole 8 on the same side. The sliding rod 9 slides with the sliding hole 8. A cylinder 10 is fixedly installed on the bottom of the left side wall of the furnace 1. The top of the cylinder column 11 of the cylinder 10 is fixedly connected to a connecting block 14. The front and rear ends of the connecting block 14 are fixedly connected to a connecting rod 13. The connecting rod 13 passes through the connecting block 14. Both ends of the connecting rod 13 are fixedly connected to the fixing blocks 12. The two fixing blocks 12 are respectively located on the front and rear sides of the left side wall of the furnace 1. The opposite ends of the two fixed blocks 12 are fixedly connected with a connecting plate 15, which extends to the right. The two connecting plates 15 are respectively rotatably connected to the sliding rod 9 on the same side.

[0020] The exteriors of the two guide holes 4 are fixedly connected to cover plates 7 , which seal the guide holes 4 .

[0021] Ventilation holes 16 are provided on the rear side and the right side of the outer wall of the furnace 1 , and the ventilation holes 16 are located below the grate 5 .

[0022] Initially, the grate 5 is laid flat in the furnace 1 and slides in the guide hole 4 via the pulley 6 to maintain a stable arrangement.

[0023] The slide rod 9 is inserted into the slide hole 8 to provide support and a sliding track for the leftmost grate 5.

[0024] When the grate needs to be vibrated, the cylinder 10 is started, and the cylinder column 11 begins to stretch up and down. The stretching and retracting of the cylinder column 11 drives the connecting block 14, the connecting rod 13 and the fixing block 12 to rise and fall together.

[0025] The slide rod 9 moves up and down along the slide hole 8 as the fixed block 12 rises and falls.

[0026] The movement of the slide bar 9 drives the leftmost grate 5 to move. Since the grates 5 are rotationally connected to each other, the entire grate sequence will be folded and unfolded in sequence, forming a wave-like vibration effect. The pulley 6 slides in the guide hole 4 to ensure that the grate 5 remains stable during the vibration process. The vibration helps the biomass particles to burn more fully in the furnace 1.

[0027] When the cylinder 10 stops working, the cylinder column 11 retracts, the connecting block 14, the connecting rod 13, and the fixed block 12 descend together, and the grate 5 is re-flattened under the action of gravity. This utility model only protects the mechanical part. The related functions realized by the software control part are not within the scope of protection of this utility model.
