[0032] In order to further illustrate the technical solution of the utility model, the following Figures 1 to 7 , we further illustrate the utility model through five embodiments according to the on-site transformation implementation situation. Embodiment 1

[0033] like Figure 1 , 4 As shown in Figures 6 and 7, a feeder capable of controlling the amount of material discharged is mainly composed of a storage tank 1 and a distribution tank 3, which are connected by a uniquely designed eccentric feeder pipe 2, and the feeder pipe 2 and the discharge port 4 at the bottom of the distribution tank 3 are arranged in a staggered manner. This design significantly enhances the controllability and accuracy of the material discharge process. The feed hopper 5 arranged on the top of the storage tank 1 is convenient for the convenient addition of raw materials. A stepper motor 6 is installed on the top of the distribution tank 3, and a distributor 7 is cleverly installed on its output shaft. The distributor is composed of a rotating shaft 701, a plurality of distribution plates 702 and an annular baffle 703. Two adjacent distribution plates 702 and the annular baffle 703 jointly construct a plurality of discharge areas 704. In addition, the reinforced connection of the support rod 34 ensures the stability of the overall structure. In the actual material discharge operation, the on-site staff controls the driver through remote control to make the stepper motor 6 drive the distributor 7 to rotate accurately, and uses different discharge areas to transport the raw materials to the discharge port 4 for accurate discharge on demand. Embodiment 2

[0034] Based on the first embodiment, Figure 2 and 3 As shown, we have added a reversible cover plate 8 on the top of the storage tank 1. This design allows on-site personnel to close the feed hopper 5 by a simple reversal operation, effectively preventing foreign matter from entering the storage tank 1, thereby ensuring the purity of the raw materials. At the same time, the handle 9 provided on the cover plate 8 greatly facilitates the use of on-site operators. Embodiment 3

[0035] To solve the problem of poor fluidity of raw materials inside the storage tank, such as Figures 2 to 5As shown in the figure, innovative structural optimizations have been carried out inside the storage tank 1 in this embodiment. First, the bottom surface inside the storage tank 1 is designed with an eccentric inclined plane, which promotes the natural flow of raw materials and reduces the risk of blockage. Secondly, rotating supports 11 are fixedly installed at the upper and lower ends of the storage tank 1 through connecting support rods 10, a stirring shaft 12 is rotatably installed between the two rotating supports 11, and then a plurality of bushings 13 are axially arranged at equal distances on the stirring shaft. A plurality of stirring rods 14 are radially installed on each bushing. In addition, a stirring ring 15 is added at the end of the stirring rod to greatly improve the stirring effect. The upper end of the stirring shaft 12 is connected to the stirring motor 17 through a coupling 16 to achieve electric drive. Finally, a specially designed stirring ring 18 at the lower end of the stirring shaft 12 is directly located inside the feeding pipe 2. Driven by the stirring motor 17, rapid stirring and smooth feeding of raw materials are achieved, effectively preventing the occurrence of blockage in the feeding pipe. Example Four

[0036] To solve the problems of shaking and spilling during the docking and hoisting process of the traditional overhead crane and the feeder, as Figure 4 and 7 shown in the figure, the hoisting structure of the storage tank 1 has been optimized in this embodiment. We innovatively designed a U-shaped hanger 19 and a matching embedding block 21. The U-shaped hanger is provided with a first insertion hole 20, while the embedding block is provided with a second insertion hole 22 and is firmly fixed on the lifting beam 23. The lifting lug 24 on the lifting beam is connected to the overhead crane beam frame to ensure the safety and stability of hoisting. The embedding block 21 is tightly connected to the U-shaped hanger 19 through a plug rod 25, and a locking knob 26 passes through the second insertion hole 22 and cooperates with the positioning hole 27 on the plug rod 25 to further enhance the firmness of the connection. In addition, the limiting groove 28 of the U-shaped hanger 19 and the limiting block 29 of the embedding block 21 cooperate with each other to effectively prevent shaking during the hoisting process. The design of the slot baffle 30 at one end of the plug rod 25 is more convenient for on-site operators to install and adjust. Example Five

[0037] To meet the usage requirements under different working conditions, as shown in the appendix Figure 7 shown in the figure, a plurality of legs 31 are added at the bottom of the storage tank 1 in this embodiment, and the legs are tightly connected by a ring 32 to form a stable support structure. A leveling foot 33 is installed on each leg, allowing on-site operators to finely adjust the feeder according to the actual terrain and working conditions to ensure that the feeder is placed stably and operates stably. This design not only improves the applicability of the feeder but also greatly extends the service life of the feeder.
