[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] 1. The present invention improves the conveying efficiency; 1) Multi-area collaborative work, the interior of the loading bin is divided into two areas by a partition plate, and raw materials can be added at the same time. This design enables the conveying plates on both sides to synchronously vibrate and convey the raw materials. Compared with the traditional single-area loading bin, the waiting time for raw materials is reduced. For example, in the traditional single-area loading bin, when there are more raw materials to be loaded at one time, it is necessary to wait for the previous batch of raw materials to be completely delivered before the next batch of raw materials can be loaded. The dual-area design of the present device can realize continuous loading and conveying, which greatly improves the work efficiency. When a minor fault occurs on the vibration component on one side and needs to be repaired, the capacity of the other side area can be appropriately expanded to ensure that the overall conveying efficiency will not be greatly reduced. 2) Composite vibration and swing assistance, the first vibration motor in the vibration component drives the conveying plate to vibrate in the vertical direction, and the swing component drives the power output rod, the first connecting rod, the second connecting rod and other components to make the conveying plate swing left and right and vibrate in the vertical direction. This composite vibration and swing mode makes the movement of raw materials on the conveying plate faster and more uniform. Compared with the conveying device that only adopts a single vibration mode, the conveying speed of raw materials can be increased by 30%-50%. For example, in some whole wheat processing production lines that require high conveying speed, this efficient conveying device can meet the rapid operation requirements of the production line and reduce the production cycle.

[0019] 2. The present invention improves the uniformity of raw materials; 1) The role of the partition rod. The partition rod arranged on the inner wall of the conveying plate can break up the clumped raw materials. In the process of conveying whole wheat raw materials, the raw materials are easy to form lumps due to factors such as moisture and static electricity. If these lumps are not broken up in time, it will affect the uniformity of the raw materials and further affect the subsequent processing quality. The partition rod continuously hits the lumps to break them up into single particles or smaller lumps, so that the raw materials can be spread more evenly on the surface of the conveying plate. 2) With the assistance of the swing component, the swing component causes the conveying plate to swing left and right, exerting force on the raw materials from different directions. This multi-directional force can further break up the lumps in the raw materials and make the distribution of the raw materials on the conveying plate more even.

[0020] 3. The present invention reduces equipment failures and maintenance costs; the detachable and adjustable design is adopted, and the partition rod inside the conveying plate is detachable, which is convenient for cleaning and replacement of the partition rod, and reduces the need to replace the conveying plate as a whole due to blockage or damage of the partition rod. The height of the partition plate inside the loading bin is adjustable, which is convenient for equipment commissioning and maintenance and reduces maintenance costs.

[0035] Specific working principle:

[0036] First, prepare for loading. Fill the whole wheat raw material into the loading bin 1 through the feed port 102 at the upper end of the loading bin 1. The partition plate 107 divides the loading bin 1 into two areas, corresponding to the discharge ports 103 on both sides. Add raw materials to the areas on both sides of the loading bin 1 and prepare for vibration conveying. The second vibration motor 106 at the bottom of the loading bin 1 is driven to move the raw materials in the loading bin 1 toward the discharge port 103. The vibration components on both sides of the loading bin 1 start working, and the raw materials in the areas on both sides are synchronously vibrated and conveyed.

[0037] When the driving motor 402 is started, the driving rod 403 rotates, driving the first bevel gear 404 to rotate. Since the first bevel gear 404 and the second bevel gear 405 are meshed with each other, the power is transmitted to the power output rod 406. When the power output rod 406 rotates, the first connecting rods 303 on both sides are driven to rotate respectively. The other end of the first connecting rod 303 drives the inner gear 302 to rotate along the outer gear ring 301 in a satellite manner. At the same time, the connecting plate 305 is driven to swing left and right through the second connecting rod 304. Since the first chute 307 is provided in the vertical direction on the outer side of the connecting plate 305, and the wall surface corresponding to the conveying plate 205 is provided with a first slider 308 for sliding connection, the conveying plate 205 performs a vertical vibration action while performing a left and right swing action. This composite vibration and swinging mode can make the agglomerated raw materials more evenly dispersed. When the raw materials form larger clumps on the conveying plate 205, simple vibration may not be able to completely break them up, while the left and right swinging action can exert force on the clumps from different directions, making them easier to disperse, improving the uniformity of the raw materials and providing better raw material conditions for subsequent processing steps.

[0038] Finally, it should be noted that the above description is only a preferred example of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or replace some of the technical features therein by equivalents.
