DETAILED DESCRIPTION

[0035] Example one: please refer to Figures 1-4 , the present application provides a technical solution: a flour processing dust recovery device, including fixed frame 5, fixed frame 5 top set up conveyor 1, conveyor 1 side set up discharging plate 7, discharging plate 7 below set up box 6, discharging plate 7 outer wall set up fixed frame 9, fixed frame 9 outer wall fixedly connected with pull rod 8, one end of pull rod 8 and the outer wall of conveyor 1 are fixedly connected, the outer wall of discharging plate 7 is provided with dust recovery mechanism 2;

[0036] Dust recovery mechanism 2 includes:

[0037] The fixed plate 201 is provided with a connecting frame 202 fixedly installed on the outer wall of the fixed plate 201, and the connecting frame 202 is fixedly connected with a connecting rod 203 on one side. The fixed plate 201 is used for connecting the fixed frame 9 and the connecting frame 202. The connecting frame 202 is a square frame structure.

[0038] The connecting cover 205 is a square sleeve structure, and a through groove 206 is formed in the inner wall of the connecting cover 205. The connecting cover 205 is fixedly connected with an arc-shaped plate 204 on the top. The arc-shaped plate 204 is fixedly connected with a motor 207 on one side. The output end of the motor 207 is fixedly connected with a rotating shaft 208. The outer wall of the rotating shaft 208 is fixedly connected with a push plate 209. The motor 207 is used to drive the rotating shaft 208 to rotate.

[0039] The connecting cover 205 is fixedly connected with an identification sensor 210 on the inner wall. The identification sensor 210 is electrically connected with the motor 207. The identification sensor 210 is a long strip shape.

[0040] The connecting cover 205 is provided with a through groove 206 in the inner wall, and a groove 212 is formed in the outer wall of the connecting cover 205. The through groove 206 is communicated with the outside of the through groove 206 through the groove 212. The groove 212 is used for realizing air communication outside.

[0041] In use, when the flour is processed, the flour needs to be put into the conveyor 1, and then transported to the discharging plate 7 through the conveyor 1. The flour is uniformly poured on the box 6 through the inclination of the discharging plate 7, and the flour is completed. When the flour is poured through the discharging plate 7, the connecting frame 202 can be fixed on the fixed frame 9 through the fixed plate 201. The fixed frame 9 is pulled by the pull rod 8 to control and adjust the angle of the discharging plate 7.

[0042] When the flour on the discharging plate 7 naturally slides into the through groove 206 in the connecting cover 205, the flour in the through groove 206 is naturally poured out from the left side of the connecting cover 205 along the inclined surface in the through groove 206. At the same time, the motor 207 is started, and the motor 207 drives the rotating shaft 208 and the push plate 209 to rotate synchronously. When the push plate 209 rotates, the flour in the through groove 206 is pushed to the left side, so as to accelerate the flour discharging speed and avoid the problem of flour jamming in the connecting cover 205, thereby ensuring that the overall flour processing efficiency is not affected. The flour is more accurately poured into the specified drop point through the opening of the connecting cover 205. The four closed connecting covers 205 reduce the dust overflow during flour pouring.

[0043] When the dial plate 209 is rotated by the rotating shaft 208, the dial plate 209 rotates clockwise, and the air below is stirred, so that the air above the flour flows from right to left, and the air in the recess 212 and the opening on the right side of the connecting cover 205 forms a negative pressure, so that the air outside is sucked into the through groove 206 through the opening on the right side of the connecting cover 205 and the recess 212, and the flour dust scattered in the open conveying of the fixed frame 5 and the discharging plate 7 is automatically recovered to the connecting cover 205 and then concentrated and poured to the designated position through the smaller opening on the right side of the connecting cover 205, thereby effectively reducing the problem of flour dust scattering in flour processing and transportation, and automatically recovering the scattered dust.

[0044] When the flour conveying amount is large, the height of the flour in the connecting cover 205 will also be high, and when passing through the through groove 206, the height of the flour will cover the recognition sensor 210 on the inner wall of the through groove 206. The recognition sensor 210 automatically detects the area covered by itself, collects and processes the information, and sends a command to the motor 207. When the covered area of the recognition sensor 210 is larger, the motor 207 controls the rotating speed of the rotating shaft 208 to be larger, so that when the flour passes through the inner wall of the through groove 206 and the flow is large, the rotating speed of the rotating shaft 208 is automatically increased to drive the dial plate 209 to rotate, and the circulation of the air above the flour is accelerated, so that the recovery speed of the dust-containing air in the recess 212 and the right side of the connecting cover 205 is automatically increased for this situation, to avoid the increase of dust scattering in the large flow dust circulation situation, and when the flow is small, the recovery speed of the air dust is reduced to ensure the rational utilization rate of energy, avoid energy waste, and ensure the targeted recovery efficiency of the dust.

[0045] Example two: please refer to Figures 1-8 On the basis of example one, the application provides a technical solution: the dial plate 209 is internally provided with an auxiliary mechanism 3, the auxiliary mechanism 3 comprises a first sliding plate 301, the first sliding plate 301 is slidingly connected to the inner wall of the dial plate 209, and the inner wall of the first sliding plate 301 slidingly connects a second sliding plate 302.

[0046] The dial plate 209 is internally provided with an internal spring, one end of the internal spring is fixedly connected to the inner wall of the dial plate 209, and the other end of the internal spring is fixedly connected to the outer wall of the second sliding plate 302. The internal spring is used to reset the first sliding plate 301 and the second sliding plate 302.

[0047] With the rotation speed of the dial plate 209 is different, the first slide plate 301 and the second slide plate 302 of the inner wall of the dial plate 209 will also be thrown outwards by different centrifugal forces, and will overcome the elastic force of the built-in spring inside the dial plate 209 to stretch outwards, thereby allowing it to automatically stretch out into the flour under the condition of fast rotation of the rotating shaft 208, and to accelerate the stirring and flow of the flour, avoiding the situation of jamming and clogging of the flour due to excessive friction;

[0048] At the same time, when the flour flows in large quantities, the first slide plate 301 and the second slide plate 302 will extend out as an extension of the dial plate 209 to increase the area of the dial plate 209, thereby further increasing the speed of air and dust recovery through the increase in speed and the increase in area of the dial plate 209, and through the rapid entry of air from the right side of the connecting cover 205, the flour passing through the through slot 206 will be accelerated, and the flour will be accelerated to be sprayed out from the left side of the through slot 206, thereby reducing the problem of a large amount of scattering and overflowing of the flour due to its lightness under free fall;

[0049] Example three: please refer to Figures 1-11 Finally, on the basis of example one and example two, the present application provides a technical solution: the rotating shaft 208 is provided with an opening and closing mechanism 4, the opening and closing mechanism 4 includes a communication slot 401, the communication slot 401 is provided in the inner wall of the rotating shaft 208, the outer wall of the connecting cover 205 is fixedly connected with an arc-shaped expansion plate 402, one side of the arc-shaped expansion plate 402 is fixedly connected with a hinged plate 403, one side of the hinged plate 403 is fixedly connected with a rotating rod 404, one side of the rotating rod 404 is fixedly connected with a circular plate 405, one side of the circular plate 405 is fixedly connected with a spring 406, one end of the spring 406 is fixedly connected with one side of the connecting cover 205.

[0050] The inside of the dial plate 209 is communicated with the inside of the communication slot 401 through the rotating shaft 208, the inside of the communication slot 401 is communicated with the inside of the arc-shaped expansion plate 402 through the connecting cover 205, and the arc-shaped expansion plate 402 and the communication slot 401 are provided with hydraulic oil.

[0051] The outer wall of the hinged plate 403 is fixedly connected with a limiting slide plate 407, the outer wall of the limiting slide plate 407 is slidingly connected with the inner wall of the connecting cover 205, and the hinged plate 403 slides in the inner wall of the connecting cover 205 through the limiting slide plate 407 to stabilize the opening and closing;

[0052] When the rotating shaft 208 drives the dial plate 209 to rotate, because the larger the flour flow is, the more area the dial plate 209 covers the recognition sensor 210, the faster the rotating speed of the rotating shaft 208 drives the dial plate 209, the more distance the first slide plate 301 and the second slide plate 302 in the inner wall of the dial plate 209 extend, the inner part of the dial plate 209 is communicated with the inner part of the communication groove 401 through the rotating shaft 208, the communication groove 401 is communicated with the inner part of the arc-shaped telescopic plate 402 through the connecting cover 205, so when the first slide plate 301 and the second slide plate 302 extend more, the hydraulic oil in the arc-shaped telescopic plate 402 is drawn into the first slide plate 301 and the second slide plate 302 through the communication groove 401, so that the first slide plate 301 and the second slide plate 302 expand and lengthen, and the arc-shaped telescopic plate 402 is shortened and the hinge plate 403 and the rotating rod 404 below are pulled to rotate and lift, so that the hinge plate 403 which is originally in a relatively closed state is lifted in this state, the larger flow-through space on the left side of the connecting cover 205 is opened, so that the efficient discharge efficiency of the flour under the condition of large flow is adapted, and under the condition of normal and conventional flour discharging, the hinge plate 403 is pulled to rotate and reset by the elastic force of the spring 406, so that the hinge plate 403 and the rotating rod 404 are rotated and reset, the rotating rod 404 is in a relatively closed state, so as to ensure the concentration and stability of the flour discharging, and avoid the problem of flour scattering and escaping due to the large opening under the condition of small flow discharging.
