[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1-5This utility model provides a technical solution: a flour conveying device, comprising: a conveying cylinder 1, a motor plate 101 fixedly connected to the bottom end of the conveying cylinder 1, bottom support rods 102 fixedly connected to both sides of the bottom end of the circumferential surface of the conveying cylinder 1, top support rods 103 fixedly connected to both sides of the top end of the circumferential surface of the conveying cylinder 1, a feeding inlet 104 fixedly embedded in the upper part of the bottom end of the conveying cylinder 1, the feeding inlet 104 communicating with the inner cavity of the conveying cylinder 1, and the lower part of the top end of the conveying cylinder 1... A feed inlet 105 is fixedly embedded, and the feed inlet 105 communicates with the inner cavity of the conveying cylinder 1. Both ends of the inner cavity of the conveying cylinder 1 are fitted with augers 106 through bearings. The bottom end of the auger 106 is connected to a motor 107. The output end of the motor 107 is fixedly connected to the center of the bottom end of the auger 106. The bottom of the motor 107 is fixedly connected to the surface of the motor plate 101. A screening component 2 is provided on the top of the feed inlet 104, and a grinding component 3 is provided on the top of the screening component 2.

[0024] Specifically: The vibrating motor 213 generates an excitation force, causing the flour on the surface of the sieve plate 211 to undergo a throwing motion. Flour that meets the size of the sieve holes in the sieve plate 211 falls through the sieve holes, while flour that does not meet the size of the sieve holes remains on the surface of the sieve plate 211. This design can sieve flour that has become damp and clumped during storage, preventing the clumped flour from affecting its flowability. The clumped flour falls into the gap between the inner grinding wall 305 and the outer grinding wall 307 and is ground by grinding blocks 306 and 308. After grinding, the flour falls from the bottom of the gap between the inner grinding wall 305 and the outer grinding wall 307. This design allows the clumped flour to be ground and then put back into the conveying device, reducing waste. Flowability refers to the ease with which materials flow under the action of gravity or external force, which directly affects conveying efficiency, energy consumption, equipment selection, and system stability.

[0025] In one embodiment, the screening assembly 2 includes a base plate 201, with a staggered groove 202 extending through the surface of the base plate 201. Four support legs 203 are fixedly connected to the bottom of the base plate 201 at equal intervals around the circumference, and four connecting columns 204 are fixedly connected to the top of the base plate 201 at equal intervals around the circumference. Springs 205 are fixedly sleeved on the surface of each of the four connecting columns 204, and connecting columns 206 are fixedly embedded in the top of the inner cavity of each of the four springs 205. A screening cylinder 207 is fixedly connected to the top of the four connecting columns 206, and a discharge port 208 is fixedly connected to the bottom of the screening cylinder 207.

[0026] Specifically, such as Figure 3-4 As shown: Four springs 205 support the device located on top of it.

[0027] In one embodiment, the discharge port 208 is connected to the inner cavity of the screening cylinder 207. The top of the screening cylinder 207 is fixedly connected to the inlet 209, which is connected to the inner cavity of the screening cylinder 207. The top of the inner cavity of the screening cylinder 207 is fixedly connected to four support rods 210 at equal intervals around the circumference. The bottom of the four support rods 210 is fixedly connected to a screening plate 211. The bottom of both sides of the circumferential surface of the screening cylinder 207 is fixedly connected to a motor plate 212, and the bottom of the two motor plates 212 is fixedly connected to a vibration motor 213.

[0028] Specifically, such as Figure 3-4 As shown: The sieve plate 211 is fixed to the inner cavity of the sieve cylinder 207 by the support rod 210, and there is a certain gap between the edge of the sieve plate 211 and the inner wall of the sieve cylinder 207. Since the lumpy flour is relatively brittle, when the lumpy flour vibrates and shakes between the sieve plate 211 and the sieve cylinder 207, it will hit the inner wall of 207 or the flour will collide with each other and break. Then, the broken flour falls into the gap between the grinding outer wall 307 and the grinding inner wall 305 under the action of vibration. The vibration motor 213 is a common vibrating sieve motor, and its specific structure will not be described here.

[0029] In one embodiment, the grinding assembly 3 includes an F-shaped support arm 301 and a grinding outer wall 307. A motor 302 is fixedly connected to the bottom of the top of the F-shaped support arm 301. A rotating shaft 303 is fixedly connected to the output end of the motor 302. Four support rods 304 are fixedly connected to the bottom of the surface of the rotating shaft 303 at equal intervals around the circumference. The other ends of the four support rods 304 are fixedly connected to the grinding inner wall 305.

[0030] Specifically, such as Figure 4-5 As shown: The top end of motor 2 302 is fixedly connected to the bottom of the top end of F-type support arm 301 to prevent motor 2 302 from shaking during operation and affecting the normal operation of this device.

[0031] In one embodiment, a plurality of grinding blocks 306 are fixedly connected at equal intervals on the circumferential surface of the grinding inner wall 305, and a plurality of grinding blocks 308 are fixedly connected at equal intervals on the circumferential cavity of the grinding outer wall 307. The top end of the surface of the rotating shaft 303 is embedded in the interior of one end of the middle part of the F-type support arm 301 through a bearing.

[0032] Specifically, such as Figure 4-5 As shown: multiple grinding blocks 306 on the surface of the inner grinding wall 305 can cooperate with multiple grinding blocks 308 on the surface of the outer grinding wall 307 to grind the clumps of flour that fall from above; the gap between the inner grinding wall 305 and the outer grinding wall 307 gradually decreases in size from top to bottom.

[0033] In one embodiment, the bottom ends of the four support legs 203 are fixedly connected to the top of the feed inlet 104, and the surface of the bottom end of the discharge outlet 208 is embedded in the inner cavity of the feed inlet 104.

[0034] Specifically, such as Figure 1 As shown: the four support legs 203 connect the base plate 201 to the feed inlet 104, which provides fixed support for the screening component 2 and the grinding component 3; the bottom end of the discharge port 208 is located in the inner cavity of the feed inlet 104, which facilitates the flour after screening and grinding to fall into the feed inlet 104 for subsequent transportation.

[0035] In one embodiment, the bottom end of the F-type support arm 301 is fixedly connected to one side of the top of the feed inlet 209, the surface of the rotating shaft 303 is embedded in the inside of the screening plate 211 through a bearing, the top surface of the grinding inner wall 305 is attached to the bottom of the screening plate 211, the circumferential surface of the grinding outer wall 307 is fixedly embedded in the inner cavity of the screening cylinder 207, and the grinding outer wall 307 is located below the screening plate 211.

[0036] Specifically, such as Figure 4 As shown: The F-type support arm 301 provides fixed support for the grinding assembly 3, and is connected to the rotating shaft 303 through the bearing, which improves the stability of the rotation of the rotating shaft 303.

[0037] Working principle: Connect this flour conveying device to an external power supply to provide power to the device. The external controller is associated with and controls motor 107, vibrating motor 213 and motor 302.

[0038] The external controller starts motor 107, vibration motor 213 and motor 302, and pours the flour to be conveyed into the feed port 209. The flour falls onto the surface of the sieve plate 211. The started vibration motor 213 generates excitation force, which causes the flour on the surface of the sieve plate 211 to be thrown. Flour that meets the size of the sieve holes in the sieve plate 211 falls through the sieve holes, while flour that does not meet the size of the sieve holes stays on the surface of the sieve plate 211.

[0039] This design allows for the sieving of flour that has become damp and clumped during storage, preventing the clumps from affecting its flowability.

[0040] The lumpy flour that does not meet the sieve hole size requirement and remains on the surface of the sieve plate 211 falls into the gap between the inner grinding wall 305 and the outer grinding wall 307 under the action of the vibrating motor 213. The output end of the second motor 302 drives the rotating shaft 303 to rotate, and the rotating shaft 303 drives the second support rod 304 and the inner grinding wall 305 to rotate. The lumpy flour that falls into the gap is ground by the first grinding block 306 and the second grinding block 308. After grinding, the flour falls from the bottom of the gap between the inner grinding wall 305 and the outer grinding wall 307.

[0041] This design allows clumps of flour to be ground and then fed back into the conveyor, reducing waste.

[0042] The falling flour passes through the sieving cylinder 207 and the discharge port 208, and finally falls into the bottom of the inner cavity of the conveying cylinder 1 through the feed inlet 104. The output end of the motor 107 drives the auger 106 to rotate. The rotating auger 106 transports the flour located at the bottom of the inner cavity of the conveying cylinder 1 to the top of the inner cavity of the conveying cylinder 1 and falls out from the discharge port 105, completing the conveying of the flour for subsequent processing.

[0043] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
