[0015] Compared with the prior art, the beneficial effects of the present invention are: 1. This invention employs a linkage control structure between the side baffle and the bottom baffle. The side baffle moves via a second telescopic component, and a rack and pinion drive a second screw to rotate, thereby causing the moving plate, connecting frame, and bottom baffle to move synchronously, achieving synchronized adjustment of the side and bottom baffles. This linkage method eliminates the need for a separate drive for the bottom baffle, simplifying the drive layout, reducing control logic, ensuring consistency and coordination of actions, and effectively avoiding material leakage, spillage, and flow fluctuations caused by baffle asynchrony. This significantly improves discharging accuracy and delivery stability. The gear, rack, and second screw transmission system is compact, provides smooth transmission, and accurate positioning, meeting the requirements of multi-station and automated delivery, improving the system's automation level and operational reliability, and reducing material loss.

[0016] 2. In this invention, an anti-clogging structure is incorporated. A third drive source continuously rotates the connecting column and multiple sets of agitator plates, creating continuous disturbance within the hopper and connecting pipe. This effectively breaks up material arching and bridging phenomena easily formed by sticky bulk materials, preventing blockage of the feeding channel at its source. Compared to traditional passive anti-clogging methods, this structure employs active stirring and dispersing, resulting in more uniform and smooth material descent, significantly reducing equipment downtime and ensuring continuous and stable operation throughout the entire process of material handling, lifting, and distribution. Simultaneously, the agitator plates rotate synchronously with the connecting column, ensuring uniform force distribution and reliable operation. This adaptable to various bulk material conditions such as distiller's grains, grains, and powders, enhancing system versatility and stability, reducing the frequency of manual unclogging, lowering labor intensity and maintenance costs, and improving overall operational efficiency and equipment lifespan.

[0017] 3. In this invention, the multi-directional material handling mechanism composed of the first support as a whole, the feeding mechanism composed of the guide frame as a whole, and the conveying structure composed of the conveyor belt as a whole are designed as independent modular structures. Each module has a clear function, which greatly improves installation and maintenance efficiency. The material handling mechanism integrates the material handling cylinder, auger, first telescopic component, and drive structure, etc. The guide frame integrates the discharge port, side baffle, bottom baffle, second telescopic component, hopper, anti-blocking structure, and linkage structure, etc. The conveying structure integrates the rotating roller, conveyor belt, and fourth drive source, etc. The three do not interfere with each other and can be quickly connected, which is convenient for flexible replacement according to different bulk material characteristics and working conditions, enhancing the system's flexibility and adaptability. The modular design simplifies the processing, manufacturing, and assembly process, reduces production and maintenance costs, and facilitates equipment upgrades and component interchangeability, improving the system's standardization and overall service life, making it more suitable for industrial batch applications and long-term stable operation.

Below each of the three discharge ports 17, there is a conveyor belt 28. The top of the guide frame 14 is provided with three second telescopic members 19. The output ends of the three second telescopic members 19 are all fixed with side baffles 20. The bottom ends of the three discharge ports 17 are all provided with bottom baffles 21. A machine box 22 is provided on one side of the bottom baffle 21.

The hopper 12 is provided with an anti-blocking structure 15 to prevent material blockage. The first bracket 2 is provided with a drive structure 5 to drive the material picking cylinder 7 to move in multiple directions.

[0022] In this embodiment, the operation of the second telescopic member 19 drives the side baffle 20 to move downward, blocking one side of the corresponding discharge port 17. At this time, the operation of the linkage structure 23 will simultaneously drive the bottom baffle 21 at the bottom of the discharge port 17 to open, realizing the synchronous action of both, simplifying the drive layout, reducing control logic, ensuring consistency and coordination of actions, and effectively avoiding material leakage, spillage and flow fluctuation caused by asynchronous baffles. The anti-blocking structure 15 can create continuous disturbance inside the hopper 12 and the connecting pipe 13, effectively breaking the material arching and bridging phenomenon that is easily formed by sticky bulk materials, and preventing the feeding channel from being blocked from the root. The three-dimensional movement of the feeding cylinder 7 is realized through the setting of the drive structure 5.

One connecting block 501 is threadedly connected to the first screw 503. The other connecting block 501 is slidably connected to a first limiting post 504.

[0024] In this embodiment, the second telescopic member 19 drives the side baffle 20 to move, and the rack 2306 and gear 2305 mesh to drive the second screw 2301 to rotate, so that the moving plate 2302 moves under the limit of the second limiting post 2303, thereby driving the bottom baffle 21 connected to the connecting frame 2304 to move, realizing the synchronous adjustment of the side baffle 20 and the bottom baffle 21. The third driving source 1501 drives the connecting post 1502 and multiple sets of actuating plates 1503 to rotate continuously, which can create continuous disturbance inside the hopper 12 and the connecting pipe 13, effectively breaking the material arching and bridging phenomenon that is easy to form in sticky bulk materials, and avoiding the blockage of the feeding channel from the root. The first driving source 502 drives the first screw 503 to rotate, so that the moving frame 3 or the moving block 4 can move in three dimensions along the X and Y axes under the limit of the connecting block 501 and the first limiting post 504, and the position of the feeding cylinder 7 can be adjusted according to the actual position of the bulk materials in the material pool 1.

The rack 2306 is guided by the limit frame 24, and the moving groove 25 provides movement space for the connecting frame 2304, ensuring the smoothness and accuracy of the operation of the linkage structure 23, avoiding the offset of the rack 2306 and the jamming of the connecting frame 2304, and improving the reliability of the system.

[0027] In this invention, the control cabinet 30 issues a material retrieval task. The drive structure 5 drives the first screw 503 to rotate via the first drive source 502, causing the moving frame 3 or moving block 4 to move in three dimensions along the X and Y axes under the limitation of the connecting block 501 and the first limiting post 504.
