DETAILED DESCRIPTION

[0022] The utility model will be further explained in detail in combination with the drawings. The drawings are simplified schematic diagrams, and only the basic structure of the utility model is schematically shown, so they only show the structure related to the utility model.

[0023] Referring to Figures 1-6 The utility model discloses a feeding hopper 1, feeding shell 2, fixedly connected with the communication pipe 3 between feeding hopper 1 and feeding shell 2, the upper end of feeding shell 2 is equipped with the feeding port 19, the right end of feeding shell 2 is equipped with the discharging port 20, two front and back symmetry's first rotating shaft 4 is rotatably connected in feeding shell 2, and the second rotating shaft 5 rotatably connected with feeding shell 2 is equipped between two first rotating shafts 4, the first rotating shaft 4 is rotatably connected with spiral blade 6, the right end of spiral blade 6 extends into the discharging port 20, a plurality of stirring members are fixedly connected on the second rotating shaft 5, the bottom of feeding hopper 1 is equipped with the pushing block 7 that can move left and right, and the pushing block 7 can be moved to the upper of communication pipe 3.

[0024] As shown in Figure 1 Feeding hopper 1 is above communication pipe 3, and communication pipe 3 is above feeding shell 2, garbage is supplied from feeding hopper 1, part enters feeding shell 2 through communication pipe 3 and feeding port 19, and another part will slowly accumulate in feeding hopper 1, so that garbage can not all fall and accumulate in feeding shell 2, leading to excessive pressure, difficult garbage conveying and large wear of conveying parts, and the garbage accumulated in feeding hopper 1 is pushed to the upper of communication pipe 3 and falls into feeding shell 2 by the pushing block 7 that can move left and right, and the pushing block 7 can be driven by a cylinder, a hydraulic cylinder or the like.

[0025] The garbage entering the feeding shell 2 is pushed by the two non-parallel and front-back symmetrical spiral blades 6, so that a small amount of garbage enters the gasification furnace for combustion. When the two spiral blades 6 rotate, the second rotating shaft 5 drives the stirring member to rotate between the two spiral blades 6. The second rotating shaft 5 can be driven by a motor and a transmission system, so as to avoid compacting the garbage when the spiral blade 6 rotates and feeds, which causes the feeding to be blocked or stuck.

[0026] As shown in Figure 6 , in order to avoid compacting the garbage when feeding, a plurality of stirring members are uniformly distributed along the axial direction of the second rotating shaft 5. Each stirring member includes four stirring protrusions uniformly distributed in a circle. The four stirring protrusions are composed of two square blocks 8 of different lengths and two sharp tapered blocks 9 staggered. Each adjacent two stirring members are staggered by ninety degrees.

[0027] During the feeding process of the spiral blade 6, the stirring member rotates continuously, and the sharp tapered block 9 can break up the garbage that is about to be compacted and continuously scatter it by the direction block 8. In this way, during the feeding process of the spiral blade 6, the garbage can be prevented from being compacted, and the wear of the parts is reduced. The square block 8 is arranged at an angle such that one diagonal of the cross section is perpendicular to the axial direction of the second rotating shaft 5. When the stirring member rotates, the vertical edge of the direction block 9 exerts force on the garbage rather than a face. In this way, the stirring member can more easily stir and scatter the garbage.

[0028] Specifically, as shown in Figure 2 , in order to avoid the garbage in the feeding hopper 1 falling directly into the feeding shell 2, causing excessive accumulation and excessive feeding pressure, which can easily cause wear of the parts, the feeding hopper 1 includes a feeding part 101, an inclined guide part 102, and a connecting part 103. The pushing block 7 is below the inclined guide part 102, and the pushing block 7 does not completely extend out of the left side slope of the inclined guide part 102 when moving the pushing block 7.

[0029] The right side of the pushing block 7 is provided with a first slope 10.

[0030] The garbage enters the feeding hopper 1 from the feeding part 101 and falls onto the pushing block 7 through the inclined guide part 102. The garbage on the inclined guide part 102 falls into the feeding shell 2 through the first slope 10. In addition, when the pushing block 7 moves left and right, the first slope 10 facilitates the garbage falling into the feeding shell 2. The feeding part 101 and the connecting part 103 are staggered, so that a part of the garbage is accumulated in the inclined guide part 102. The garbage is orderly pushed by the movement of the pushing block 7, avoiding accumulation in one place and causing pressure and wear to the feeding spiral blade.

[0031] In order to make the rotation of the first rotating shaft 4 and the spiral blade 6 fixedly connected to the first rotating shaft 4 more stable, the bottom right end of the feeding shell 2 is provided with a sloping connection port 11, and the upper right end of the feeding shell 2 is fixedly connected with a baffle 12. The first rotating shaft 4 and the second rotating shaft 5 are rotatably connected to the baffle 12.

[0032] Furthermore, in order to prevent the temperature inside the feeding shell 2 and the connecting pipe 3 from becoming too high and causing a fire, a temperature sensor 13 is fixedly connected to the lower side of the connecting pipe 3, and a nozzle 14 controlled by the temperature sensor 13 is fixedly connected to the feeding hopper 1, with the nozzle 14 located above the connecting pipe 3.

[0033] like Figure 2 As shown, the temperature sensor 13 is connected to a controller. The controller monitors the temperature sensor 13's measurement value every moment. If the temperature sensor 13 detects that the temperature of the area of ​​the feeding shell 2 and the connecting pipe 3 is too high, the controller sends a signal to the nozzle 14 and turns on the switch to control the nozzle, and the nozzle sprays water to cool it down.

[0034] Specifically, in order to realize the rotation of the two spiral blades 6 to transport garbage, the first rotating shaft 4 extends outward through the feeding housing 2 and is fixedly connected to a worm gear 15. The first drive motor 16 is fixedly installed on the feeding housing 2. The output end of the drive motor 16 is fixedly connected to an output shaft 17. Two symmetrical worms 18 are fixedly connected to the output shaft 17. The worms 18 correspond one-to-one with the worm gears 15.

[0035] The upper right side of the feeding shell 2 is provided with a second inclined surface 21.

[0036] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
