[0036] Working principle: Before using the biomass boiler material conveying equipment, you need to check the overall condition of the device to make sure it can work normally. Figure 1 - Figure 5 As shown, firstly, the raw material is poured in through the feeding port 103, and then the bidirectional motor 218 is started, and the cam 205 is driven to rotate through the connecting shaft 219, and the connecting rod 207 is pulled to rotate as the cam 205 rotates;

[0037] Thus, the first slider 203 and the second slider 204 slide in the inner slot 202 at the same time, and as the cam 205 rotates, the first slider 203 and the second slider 204 move in the same direction and in opposite directions synchronously to achieve reciprocating motion;

[0038] When the first slider 203 moves, it drives the ash tray 210 to move left and right through the support block 209. When the second slider 204 moves, it drives the tray 213 to move through the bracket 211, so that the tray 213 drives the screen plate 217 inside it to shake, and finally the raw materials are spread on the screen plate 217 with the shaking. At this time, small particles of material will fall into the ash tray 210, and then the small particles of material in the ash tray 210 will be sucked away through the connecting pipe 212, thereby avoiding the situation where small particles of raw materials fly during screening;

[0039] By starting the hydraulic rod 221, the angle of the tray 213 can be controlled, so that when it is necessary to discharge the material, the tray 213 is tilted, so that the screened raw materials are poured into the boiler through the discharge port 102, and the tilt angle of the tray 213 can also control its discharge speed. Even when one side of the tray 213 is lifted up, the material cannot be discharged, which increases the screening time of the raw materials and fully ensures the effectiveness of the screening.

[0040] When the sieve plate 217 is blocked and needs to be replaced, the rotating plate 306 is pressed to rotate it. At this time, the positioning teeth 308 are disengaged from the restriction of the limiting teeth 307. At this time, the sieve plate 217 can be pulled out of the tray 213 by pulling the fixing block 301, and finally the sieve plate 217 can be quickly disassembled and maintained to avoid blockage of the sieve plate 217 and ensure the stability of screening.
