A reinforcing beam 14 is provided between adjacent support columns 8. A support seat 15 is provided on the top of the crossbeam 9. An L-shaped support plate 10 is provided on one side of the top of the support seat 15, which is placed outside the conveyor belt 7, and a support frame 11 for supporting the hopper body 1 is provided on the other side.

[0021] Specifically, the construction of the assembled steel structure support 3: This support is the basic load-bearing structure of the entire system. First, several independent concrete foundations are fabricated according to design requirements, and anchor bolts are pre-embedded in the foundations. Then, four support columns 8 with steel bases 13 are hoisted into place and firmly connected to the concrete foundations with anchor bolts. The support columns 8 are preferably made of H-beams or square tubes to provide good axial load-bearing and bending resistance. Afterwards, along the running direction of the conveyor belt 7, a crossbeam 9 is installed on the top of the support columns 8 on the same side, and reinforcing beams 14 are installed between adjacent support columns 8. These are fixed with bolts or welding to form a stable frame structure, ensuring connection strength and rigidity.

[0022] As per the instruction manual Figure 1 , 3As shown in Figure 4: The lower-mounted conveyor belt channel 2 also includes a drive roller 4, several support rollers 5, and driven rollers 6 supported between the assembled steel structure support parts 3. A matching conveyor belt 7 is provided between the drive roller 4, several support rollers 5, and driven rollers 6. The L-shaped support plate 10 is rotatably connected to the drive roller 4, several support rollers 5, and driven rollers 6. A motor 12 is provided on the outer wall of one side of the L-shaped support plate 10. The output end of the motor 12 is fixedly connected to one end of the drive roller 4. The bottom of the hopper body 1 is provided with a discharge port 17, and an electric motor is provided on the discharge port 17. The slide gate valve 18 and the discharge port 17 are provided with outwardly expanding anti-splash plates 19 on both sides of the discharge port 7. Specifically, the hopper body 1 has a typical funnel-shaped structure with a larger top and a smaller bottom. The discharge port 17 is located at the bottom. An electric slide gate valve 18 is installed on the discharge port 17. The opening and closing of the valve can be easily controlled by an electrical controller, thereby controlling the release of materials. When the material falls from the discharge port 17, the anti-splash plates 19 can play a role in guiding and restraining the flow, preventing the material from splashing outside the conveyor belt and keeping the site environment clean.

[0023] As per the instruction manual Figure 1 , 2 As shown: The two side walls of the hopper body 1 are symmetrically provided with support legs 16 that are fixedly connected to the bottom of the support frame 11. The support column 8 is fixed to the reinforcing beam 14, the support column 8 is fixed to the crossbeam 9, the crossbeam 9 is fixed to the support seat 15, and the support frame 11 is fixed to the support legs 16 by high-strength bolts or welding. The connection is reliable and the overall integrity is good. It is suitable for permanent or long-term fixed occasions. The L-shaped support plate 10 and the support frame 11 are fixedly connected to the support seat 15 by high-strength bolts. The support seat 15 is provided with several through holes 20 for high-strength bolts to pass through. The L-shaped support plate 10 and the support frame 11 are provided with several slotted holes 21 for high-strength bolts to pass through. During assembly, the high-strength bolts pass through the slotted holes 21 and the through holes 20 to connect them. Using the adjustment margin provided by the slotted holes 21, the position of the L-shaped support plate 10 and the support frame 11 can be precisely adjusted before tightening the bolts, so as to ensure the relative position of the hopper outlet and the conveyor belt. This is crucial for the stable operation of the equipment.

[0024] Specifically, the installation of the conveyor belt channel 2 and the hopper body 1 is as follows: A support base 15 is welded or bolted to the top of the crossbeam 9. The support base 15 is a thickened steel plate, serving as a connecting platform. An L-shaped support plate 10 is installed on one side of the top of the support base 15, with its vertical surface facing inwards, for installing the drive roller 4, several support rollers 5, and driven rollers 6. A support frame 11 for supporting the hopper body 1 is installed on the other side of the top of the support base 15. The support frame 11 is designed according to the shape of the bottom of the hopper body 1, typically a rectangular or ring frame. Subsequently, the lower-mounted conveyor belt channel... The active roller 4, several support rollers 5, and driven roller 6 of the 2 are installed between two opposing L-shaped support plates 10. All rollers are rotatably connected to the L-shaped support plates 10 through bearing seats. The conveyor belt 7 is fitted between the active roller 4, several support rollers 5, and driven roller 6 and tensioned. A motor 12 is installed on the outer wall of one side of the L-shaped support plate 10. Its output shaft is fixedly connected to one end of the active roller 4 through a coupling, serving as the power source for the conveyor belt 7. Finally, the hopper body 1 with support legs 16 is hoisted onto the support frame 11, and the support legs 16 are welded and fixed to the support frame 11.

[0025] The control method of this utility model is through a controller. The controller adopts existing known mature technology, which is not shown in the figure and will not be described in detail here. The control circuit of the controller can be implemented by those skilled in the art through simple programming. The power supply is also common knowledge in the field. Furthermore, this utility model is mainly used to protect mechanical devices, so the control method and circuit connection will not be explained in detail here.

[0026] The principle of this utility model Work process: The material is stored in the silo body 1. When it needs to be discharged, the motor 12 is started to drive the drive roller 4 to rotate. Under the combined action of the support roller 5 and the driven roller 6, the conveyor belt 7 is driven to start running. Then, the electric slide valve 18 is opened by the controller. The material falls from the discharge port 17 onto the conveyor belt 7 under the action of gravity. Guided by the anti-splash plate 19, it is smoothly transported to the next process by the conveyor belt 7. When discharging is stopped, the electric slide valve 18 is closed first. After the material on the conveyor belt 7 has been basically transported, the motor 12 is stopped.

[0027] This invention significantly shortens the construction cycle: the main components of the device are prefabricated in the factory, and only foundation construction and bolt welding assembly are required on site, eliminating the long formwork, reinforcement, and curing process of traditional concrete structures, thus greatly improving construction speed; it significantly reduces overall costs: the steel structure is lightweight, which reduces the requirements for the foundation and reduces investment in foundation engineering; standardized factory production can improve material utilization, reduce on-site wet work and construction waste, and reduce labor and management costs; it offers high flexibility and reusability: the entire under-mounted conveyor belt channel 2 is easy to disassemble, relocate, and reassemble. When the production line is adjusted, the material yard is relocated, or the project ends, the under-mounted conveyor belt channel 2 can be completely dismantled and rebuilt in another location, realizing asset preservation and recycling, which meets the requirements of green environmental protection and sustainable development.
