Therefore, the drawings and descriptions are considered to be exemplary and non-restrictive in nature.

[0028] The embodiments of the present utility model are described in detail below with reference to the accompanying drawings.

[0029] Embodiment 1:

[0030] like Figure 1-5 As shown, a lime kiln feeding device comprises a mounting plate 2 mounted above a kiln mouth 1, a mixing plate 8 is fixedly connected to one side of the mounting plate 2, a top cover 3 is fixedly connected above the mixing plate 8, a driving motor 4 is fixedly connected above the top cover 3, a driving shaft 13 is fixedly connected to the power output end of the driving motor 4, a crushing assembly is fixedly connected to one end of the driving shaft 13, a spreading pipe 21 is fixedly connected to the bottom of the driving shaft 13, and a discharge plate 22 is fixedly connected to one end of the spreading pipe 21;

[0031] The crushing assembly includes a downward pressure spring 18, a driving boss 17, a rotating collar 16 and a crushing roller 11, wherein one end of the driving boss 17 is fixedly connected to the driving shaft 13, one end of the rotating collar 16 is slidably connected to the driving boss 17, one end of the crushing roller 11 is rotatably connected to the rotating collar 16, one end of the downward pressure spring 18 is rotatably connected to the top cover 3, and the other end of the downward pressure spring 18 is fixedly connected to the rotating collar 16;

[0032] When loading, limestone mixed with coke is put into the top cover 3 from one side and falls onto the mixing plate 8. At this time, the driving motor 4 works to drive the driving shaft 13 to rotate, and the driving boss 17 drives the rolling roller 11 on one side to rotate while further crushing and mixing the material above the mixing plate 8. Then the material falls from one side of the mixing plate 8 to the spreading pipe 21. The spreading pipe 21 can rotate with the driving shaft 13 to evenly spread the material into the kiln. The unloading plate 22 is an elongated rectangle, and the crushed and mixed material can be more evenly spread into the kiln to prevent the kiln from being biased.

[0033] In this embodiment, a feed opening 9 is provided at one end of the top cover 3, a plurality of screening slots 10 are provided at the other end of the mixing plate 8, a gear ring 15 is fixedly connected to one side of the top cover 3, a driving gear 12 is meshed at one end of the gear ring 15, and one end of the driving gear 12 is fixedly connected to the rolling roller 11;

[0034] The material discharge port 9 is located on the opposite side of the screening slot 10, so that the material can be at least squeezed and crushed by the crushing roller 11 before falling. The driving gear 12 can cooperate with the gear ring 15 to allow the crushing roller 11 to rotate to improve the crushing effect.

[0035] In this embodiment, a material receiving funnel 19 is fixedly connected below the screening trough 10, and a material discharge sleeve 20 is fixedly connected to one end of the material receiving funnel 19. One end of the material discharge sleeve 20 is rotatably connected to the driving shaft 13 and the material spreading pipe 21. The bottom of the material discharge sleeve 20 has a groove, which can receive the falling material and pass it to the material spreading pipe 21.

[0036] In this embodiment, a vibration plate 23 is slidably connected above the blanking plate 22, and a return spring 24 and a support rod 25 are fixedly connected at both ends of the vibration plate 23, and a roller 26 is rotatably connected at one end of the support rod 25;

[0037] A plurality of extrusion bosses 27 are fixedly connected to the inner side of the kiln mouth 1, and limited baffles 28 are fixedly connected to both sides of the extrusion bosses 27;

[0038] As the unloading plate 22 rotates following the driving shaft 13, the roller 26 at one end of the upper vibration plate 23 will move due to the fit with the extrusion boss 27, allowing the vibration plate 23 to move back and forth, thereby allowing the material falling onto the top of the vibration plate 23 to be evenly scattered, thereby improving the uniformity of material spreading. At the same time, the repeated staggering of the openings of the vibration plate 23 and the unloading plate 22 can further crush larger particles, and the limit baffle 28 can prevent the roller 26 from running off track.

[0039] In this embodiment: when loading, limestone mixed with coke is put into the top cover 3 from one side and falls onto the mixing plate 8. At this time, the driving motor 4 works to drive the driving shaft 13 to rotate, and the rolling roller 11 on one side is driven by the driving boss 17 to rotate, and the material above the mixing plate 8 is further crushed and mixed. Then the material falls from one side of the mixing plate 8 to the spreading pipe 21. The spreading pipe 21 can rotate with the driving shaft 13 to evenly spread the material into the kiln, and the unloading plate 22 is an elongated rectangle, and the crushed and mixed material can be more evenly spread into the kiln to prevent the kiln from being biased.

[0040] The material discharge port 9 is located on the opposite side of the screening slot 10, so that the material can be at least squeezed and crushed by the crushing roller 11 before falling. The driving gear 12 can cooperate with the gear ring 15 to allow the crushing roller 11 to rotate to improve the crushing effect;

[0041] As the unloading plate 22 rotates following the driving shaft 13, the roller 26 at one end of the upper vibration plate 23 will move due to the fit with the extrusion boss 27, allowing the vibration plate 23 to move back and forth, thereby allowing the material falling onto the top of the vibration plate 23 to be evenly scattered, thereby improving the uniformity of material spreading. At the same time, the repeated staggering of the openings of the vibration plate 23 and the unloading plate 22 can further crush larger particles, and the limit baffle 28 can prevent the roller 26 from running off track.
