Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0027] The following is a further detailed description of this application in conjunction with the attached Figures 1-9 This application discloses an automatic feeding device for a flour mill. Refer to

[0028] This application embodiment discloses an automatic feeding device for a flour mill. Refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 and Figure 9, an automatic feeding device for a grinding mill, comprising a feeding machine body 1. The feeding machine body 1 includes a tank body 101. The top of the inner cavity of the tank body 101 is communicated with a feeding pipe 107. The bottom of the inner cavity of the tank body 101 is communicated with a connecting pipe 102. The bottom of the connecting pipe 102 is communicated with a horizontal pipe 103. The right side of the horizontal pipe 103 is fixedly connected with a first motor 106. The output end of the first motor 106 penetrates into the inner cavity of the tank body 101 and is fixedly connected with a screw rod 109. The left side of the screw rod 109 is movably connected to the left side of the inner cavity of the horizontal pipe 103. The right side of the bottom of the inner cavity of the horizontal pipe 103 is communicated with a discharge pipe 104. The bottom of the surface of the discharge pipe 104 is fixedly connected with a flange 105. A screening mechanism 2 is arranged at the bottom right side of the tank body 101.

[0029] Referring to Figure 1 , Figure 2 , Figure 5 and Figure 6 , the screening mechanism 2 includes a second motor 201. The left side of the second motor 201 is installed on the right side of the tank body 101. The output end of the second motor 201 penetrates into the inner cavity of the tank body 101 and is fixedly connected with a turntable 217. A disc 215 is installed on the left side of the turntable 217. Connecting pieces 214 are movably connected to both the left side of the turntable 217 and the right side of the disc 215. The top of the surface of the connecting piece 214 is movably connected with a connecting plate 210. The top of the connecting plate 210 is fixedly connected with a push rod 209. The top of the push rod 209 is fixedly connected with a push plate 212. Outer columns 206 are movably connected to the surfaces of both the push rod 209 and the push plate 212. The top of the outer column 206 is fixedly connected with a screening plate 204. The surface of the screening plate 204 is movably connected to the inner cavity of the tank body 101. By starting the second motor 201, the rotation of the turntable 217 is driven by the operation of the second motor 201. The rotation of the positioning rod 216 is driven by the rotation of the turntable 217, and the rotation of the disc 215 is driven thereby. The rotation of the support column 208 in the inner cavity of the tank body 101 is driven by the rotation of the disc 215. When the positioning rod 216 rotates, the bottom and top of the connecting piece 214 rotate around the positioning rod 216 and the rotating shaft 213 respectively while moving upward, thereby pushing the rotating shaft 213 upward. The movement of the connecting plate 210 is driven by the movement of the rotating shaft 213. The upward movement of the push rod 209 and the push plate 212 in the inner cavity of the outer column 206 is pushed by the movement of the connecting plate 210, and the upward movement of the outer column 206 is pushed thereby. The upward movement of the screening plate 204 is further pushed thereby. The movement of the slider 205 on the surface of the fixed rod 207 is driven by the movement of the screening plate 204, and the shock-absorbing spring 203 is compressed accordingly. On the contrary, when the outer column 206 loses the thrust, the shock-absorbing spring 203 will restore its deformation, so that the slider 205 returns to its original position, and then the screening plate 204 returns to its original position, and reciprocating motion is performed in this way. Thus, not only can the function of uniformly screening the material be achieved, but also the effect of preventing blockage inside the subsequent connecting pipe 102 can be realized.

[0030] Refer to Figure 5 and Figure 6 Figure 6 , a support column 208 is fixedly connected to the left side of the disc 215. The left side of the surface of the support column 208 is movably connected to the left side of the inner cavity of the tank body 101 through a bearing. The bottom of the right side of the disc 215 and the bottom of the left side of the turntable 217 are both fixedly connected with positioning rods 216. The surface of the positioning rods 216 is movably connected to the bottom of the inner cavity of the connecting piece 214. The bottom of the inner cavity of the connecting plate 210 is fixedly connected with a rotating shaft 213. The surface of the rotating shaft 213 is movably connected to the top of the inner cavity of the connecting piece 214. Through the arrangement of the support column 208, the disc 215 in the working state can be supported and stabilized. Through the arrangement of the positioning rods 216 and the connecting plate 210, the connecting piece 214 can smoothly rotate and move up and down in the inner cavity of the connecting plate 210, on the left side of the turntable 217 and on the right side of the disc 215, thereby achieving the effect of vibrating the screening plate 204, and further realizing the effect of screening the materials on the top of the screening plate 204.

[0031] Refer to Figure 5 Figure 5 , a fixed frame 211 is fixedly connected to the surface of the second motor 201. Four corners on the left side of the fixed frame 211 are fixedly connected with support rods 202. The left sides of the support rods 202 are fixedly connected to the right side of the tank body 101. Through the arrangement of the fixed frame 211 and the support rods 202, the second motor 201 in the working state can be supported and stabilized, and the phenomenon that the second motor 201 shakes and collapses during the working process can be avoided.

[0032] Refer to Figure 3 and Figure 5 Figure 5 , inner grooves 108 are formed in the four circumferences of the inner cavity of the tank body 101. Fixed rods 207 are fixedly connected to the inner cavities of the inner grooves 108. Sliders 205 are movably connected to the bottoms of the surfaces of the fixed rods 207. The inner sides of the sliders 205 are fixedly connected to the surfaces of the screening plates 204. Shock-absorbing springs 203 are sleeved on the tops of the surfaces of the fixed rods 207. The tops of the shock-absorbing springs 203 are fixedly connected to the tops of the inner cavities of the inner grooves 108. The bottoms of the shock-absorbing springs 203 are fixedly connected to the tops of the sliders 205. Through the arrangement of the fixed rods 207, the screening plates 204 in the moving state can be guided, and the phenomenon that the screening plates 204 deviate during the moving process can be prevented. Through the arrangement of the shock-absorbing springs 203, when the screening plates 204 move, the sliders 205 will move, so as to absorb the generated force. Further, when the screening plates 204 lose force, the sliders 205 will return to their original positions, thereby achieving the effect of damping the screening plates 204 in the vibrating state.

[0033] Refer to Figure 1 , Figure 2 , Figure 7 , Figure 8and Figure 9 , a splash-proof mechanism 3 is provided at the top of the surface of the feed pipe 107. The splash-proof mechanism 3 includes a connecting frame 301. The bottom of the inner cavity of the connecting frame 301 is fixedly connected to the top of the surface of the feed pipe 107. A protection plate 304 is movably connected in the inner cavity of the connecting frame 301. The front side and the back side of the left side of the protection plate 304 are both fixedly connected with a first mounting plate 305. The front side and the back side of the left side of the connecting frame 301 are both fixedly connected with a second mounting plate 307. The left side of the second mounting plate 307 is fixedly connected with a positioning frame 312. The top and the bottom of the left side of the first mounting plate 305 are both fixedly connected with a support frame 310. An irregular rod 311 is movably connected in the inner cavity of the support frame 310. The outer side of the bottom of the irregular rod 311 is clamped and connected to the top of the inner cavity of the positioning frame 312. By manually pulling the pull ring 306 to the right, the movement of the pull ring 306 drives the protection plate 304 to move. Through the movement of the protection plate 304, the guide block 303 slides to the right on the surface of the guide rod 302. At the same time, through the movement of the protection plate 304, the first mounting plate 305 is driven to move. Through the movement of the first mounting plate 305, the support frame 310 is driven to move. Through the movement of the support frame 310, the irregular rod 311 is driven to move. When the irregular rod 311 contacts the positioning frame 312, the inclined surface at the top of the positioning frame 312 causes the irregular rod 311 to move upward. And at the same time, the limiting plate 309 slides on the surface of the moving column 314, and then the return spring 313 is compressed. Subsequently, when the irregular rod 311 reaches the specified position, the limiting plate 309 will return to its original position under the action of the return spring 313, and then drive the irregular rod 311 to be clamped in the inner cavity of the positioning frame 312, thereby achieving the effect of preventing dust from flying out of the inner cavities of the feed pipe 107 and the tank body 101.

[0034] Refer to Figure 2 , guide rods 302 are fixedly connected to the front side and the back side of the inner cavity of the connecting frame 301. The right side of the surface of the guide rod 302 is movably connected with a guide block 303. The inner side of the guide block 303 is fixedly connected to the outer side of the protection plate 304. A pull ring 306 is fixedly connected to the left side of the protection plate 304. The pull ring 306 is arranged in a ring structure. Through the arrangement of the guide rod 302, the function of guiding the protection plate 304 in the moving state is achieved, preventing the protection plate 304 from shifting during the movement. Through the arrangement of the pull ring 306, it is more convenient for the operator to pull the protection plate 304.

[0035] Refer to Figure 8 and Figure 9, a limiting plate 309 is fixedly connected to the bottom of the special-shaped rod 311. Moving columns 314 are movably connected to the four corners inside the limiting plate 309. The top of the moving column 314 is fixedly connected to the bottom of the support frame 310. A limiting block 315 is fixedly connected to the bottom of the moving column 314. A return spring 313 is sleeved on the surface of the moving column 314. The top of the return spring 313 is fixedly connected to the bottom of the support frame 310, and the bottom of the return spring 313 is fixedly connected to the top of the limiting plate 309. A pull rod 308 is fixedly connected to the bottom on the left side of the special-shaped rod 311. Through the arrangement of the moving column 314, the function of guiding the limiting plate 309 and the special-shaped rod 311 in the moving state is achieved. Through the arrangement of the limiting block 315, the effect of limiting the limiting plate 309 in the moving state is realized, avoiding the phenomenon that the limiting plate 309 falls off from the surface of the moving column 314. Through the arrangement of the pull rod 308, it is more convenient for the operator to pull the special-shaped rod 311 in the disassembled state.

[0036] Working principle: First, connect the flange 105 with the grinding mill, so as to install and connect the discharge pipe 104 and the grinding mill. After the discharge pipe 104 is installed, start the second motor 201. The rotation of the second motor 201 drives the turntable 217 to rotate. The rotation of the turntable 217 drives the positioning rod 216 to rotate, and then drives the disc 215 to rotate. The rotation of the disc 215 drives the support column 208 to rotate in the inner cavity of the tank body 101. The rotation of the positioning rod 216 makes the bottom and top of the connecting piece 214 rotate around the positioning rod 216 and the rotating shaft 213 respectively while moving upward, and then pushes the rotating shaft 213 to move upward. The movement of the rotating shaft 213 drives the connecting plate 210 to move. The movement of the connecting plate 210 pushes the push rod 209 and the push plate 212 to move upward in the inner cavity of the outer column 206, and pushes the outer column 206 to move upward, and then pushes the screening plate 204 to move upward. The movement of the screening plate 204 drives the slider 205 to move on the surface of the fixed rod 207, and then the shock-absorbing spring 203 is compressed. On the contrary, when the outer column 206 loses the thrust, the shock-absorbing spring 203 will restore its deformation, so that the slider 205 returns to its original position, and then the screening plate 204 returns to its original position, and reciprocates in this way. This can not only evenly screen the materials, but also prevent blockage in the subsequent connecting pipe 102. Secondly, manually pull the pull rod 308 upward. The movement of the pull rod 308 drives the special-shaped rod 311 to move in the inner cavity of the support frame 310, and makes the surface of the special-shaped rod 311 disengage from the inner cavity of the positioning frame 312. Then manually pull the pull ring 306 to the left. The movement of the pull ring 306 drives the protective plate 304 to move, and drives the guide block 303 to slide on the surface of the guide rod 302. Then the operator can pour the materials into the inner part of the feeding pipe 107. After the materials are poured, manually pull the pull ring 306 to the right. The movement of the pull ring 306 drives the protective plate 304 to move. The movement of the protective plate 304 makes the guide block 303 slide to the right on the surface of the guide rod 302. At the same time, the movement of the protective plate 304 drives the first mounting plate 305 to move. The movement of the first mounting plate 305 drives the support frame 310 to move. The movement of the support frame 310 drives the special-shaped rod 311 to move. When the special-shaped rod 311 contacts the positioning frame 312, the inclined surface at the top of the positioning frame 312 makes the special-shaped rod 311 move upward, and at the same time makes the limiting plate 309 slide on the surface of the moving column 314, and then the return spring 313 is compressed. Then when the special-shaped rod 311 reaches the specified position, the limiting plate 309 will return to its original position under the action of the return spring 313, and then drive the special-shaped rod 311 to be clamped in the inner cavity of the positioning frame 312, so as to prevent dust from flying out of the inner cavities of the feeding pipe 107 and the tank body 101. Finally, start the first motor 106,The operation of the first motor 106 drives the screw rod 109 to rotate, thereby achieving the function of transporting materials. Subsequently, the materials are screened by the screening plate 204 in the inner cavity of the tank body 101, enter the interior of the connecting pipe 102, and then enter the interior of the horizontal pipe 103. Then, they are transported by the screw rod 109 and discharged into the interior of the pulverizer through the discharge pipe 104.,
