[0004] However, in practical applications, unloading platforms are commonly used in construction to transport building materials from higher to lower levels. However, most existing unloading platforms rely on manual or simple mechanical controls, making it difficult to control the amount of material unloaded. This often results in too much or too little material being unloaded, affecting construction efficiency and potentially causing material waste or safety hazards. Utility Model Content

[0005] The purpose of this invention is to provide a material unloading platform for construction, addressing the issues raised in the background section. Material unloading platforms are commonly used in construction processes to transport building materials from higher to lower levels. However, most existing unloading platforms rely on manual or simple mechanical control methods, making it difficult to control the unloading volume. This often results in excessive or insufficient material during unloading, affecting construction efficiency and potentially causing material waste or safety hazards.

[0006] To achieve the above objectives, this utility model provides the following technical solution: including a lower mounting bracket and an upper mounting bracket;

[0007] A reduction motor is fixedly mounted on the rear support of the lower mounting frame. A first pulley is fixedly mounted on the inner drive shaft of the reduction motor. A second pulley is connected to the outer end of the first pulley via a belt drive. A drive shaft is fixedly mounted in the middle of the second pulley. A belt roller is fixedly mounted on the outer curved surface of the middle of the drive shaft. A conveyor belt for conveying materials is driven to the outer end of the belt roller. An upper support frame is fixedly mounted on the upper side of the lower mounting frame. An upper support roller for rolling support of the upper end of the conveyor belt is rotatably connected to the upper end of the upper support frame via a pin. A lower support is fixedly mounted on the lower side of the lower mounting frame. The support frame includes a lower support roller rotatably connected to the lower end of the conveyor belt via a pin. An opening groove is fixedly installed on the inner side of the upper end of the lower mounting frame. A limit groove is fixedly connected to the rear end of the opening groove. A discharge hopper is fixedly installed on the upper end of the limit groove. A discharge hopper is fixedly connected to the upper end of the discharge hopper. Vibration motors are fixedly installed on both sides of the lower end of the discharge hopper. An extension frame is fixedly installed in the middle of the upper end of the lower mounting frame. A hydraulic telescopic rod is rotatably connected to the inner front end of the extension frame via a pin. An arc-shaped limit plate for blocking and limiting the inner wall of the limit groove is rotatably connected to the rear end of the extension frame via a pin.

[0008] Preferably, the drive shaft is rotatably connected to the rear end of the lower mounting frame via a bearing seat.

[0009] Preferably, there are several upper support frames, which are symmetrically distributed from front to back on the upper side of the lower mounting frame.

[0010] Preferably, a limiting side plate for limiting the upper sides of the conveyor belt is fixedly installed on the front side of the upper end of the lower mounting frame.

[0011] Preferably, the outer end of the unloading hopper is fixedly installed on the inner side of the upper end of the upper mounting frame.

[0012] Preferably, there are two vibration motors, which are symmetrically distributed on both sides of the lower end of the unloading hopper.

[0013] Preferably, the hydraulic telescopic rod is connected to a hydraulic control cylinder via a hydraulic pipeline, and the telescopic portion at the rear end of the hydraulic telescopic rod is rotatably connected to the outer upper end of the arc-shaped limiting plate via a pin.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. When materials are fed into the unloading hopper, they will be discharged downwards into the limiting groove due to gravity. When the materials are discharged into the limiting groove, the arc-shaped limiting plate will block and limit the inner wall of the limiting groove, causing the materials to accumulate in the limiting groove and the unloading hopper. When the materials accumulate in the limiting groove and the unloading hopper, the hydraulic telescopic rod is retracted by controlling the opening. When the hydraulic telescopic rod retracts, it will drive the arc-shaped limiting plate to swing open. When the arc-shaped limiting plate swings open, the materials accumulated in the limiting groove and the unloading hopper can be discharged downwards into the opening groove and the upper end of the conveyor belt. By controlling the degree of swing opening of the arc-shaped limiting plate, the downward discharge amount of the materials can be controlled. At the same time, by controlling the opening of the vibration motor, the materials in the unloading hopper will be vibrated to prevent the materials from accumulating in the unloading hopper and becoming blocked and difficult to discharge. Thus, it is possible to unload construction materials while facilitating the control of the material discharge amount.

[0016] 2. When the reduction motor is turned on, it drives the first pulley to rotate. When the first pulley rotates, it drives the second pulley to rotate via belt drive. When the second pulley rotates, it drives the transmission shaft to rotate. When the transmission shaft rotates, it drives the belt roller to rotate. When the belt roller rotates, it works with the upper support roller and the lower support roller to drive the conveyor belt to rotate and convey. When the conveyor belt rotates and conveys, the material at the upper end of the conveyor belt can be conveyed outward. The limiting side plate limits the material conveyed at the upper end of the conveyor belt, thereby realizing the unloading of material and facilitating the outward conveying of the unloaded material.

A second pulley 5 is connected to the outer end of the first pulley 4 via a belt drive. A drive shaft 6 is fixedly mounted in the middle of the second pulley 5 and is rotatably connected to the rear end of the lower mounting frame 1 via a bearing seat. A belt roller 7 is fixedly mounted on the outer curved surface of the middle of the drive shaft 6. A conveyor belt 8 for conveying materials is connected to the outer end of the belt roller 7. An upper support is fixedly mounted on the upper side of the lower mounting frame 1. The support frame 9, and there are several upper support frames 9, which are symmetrically distributed from front to back on the upper side of the lower mounting frame 1. The upper end of the upper support frame 9 is rotatably connected to an upper support roller 10 for rolling support of the upper end of the conveyor belt 8 via a pin. A lower support frame 11 is fixedly installed on the lower side of the lower mounting frame 1. The lower end of the lower support frame 11 is rotatably connected to a lower support roller 12 for rolling support of the lower end of the conveyor belt 8 via a pin, so that the conveyor belt 8 is rotated and conveyed by the belt roller 7 in cooperation with the upper support roller 10 and the lower support roller 12. A limiting side plate 13 for limiting the upper sides of the conveyor belt 8 is fixedly installed on the front side of the upper end of the mounting frame 1. An opening groove 14 is fixedly installed on the inner side of the upper end of the lower mounting frame 1. The rear end of the opening groove 14 is fixedly connected to a limiting groove 15. A discharge hopper 16 is fixedly installed on the upper end of the limiting groove 15. A discharge hopper 16 is fixedly connected to the upper end of the discharge hopper 16, and the outer end of the discharge hopper 16 is fixedly installed on the inner side of the upper end of the upper mounting frame 2, so that the discharge hopper 16 is fixedly supported by the upper mounting frame 2. Vibration motors 17 are fixedly installed on both sides of the lower end of the discharge hopper 16. There are two vibration motors 17, which are symmetrically distributed on both sides of the lower end of the unloading hopper 16. An extension frame 18 is fixedly installed in the middle of the upper end of the lower mounting frame 1. A hydraulic telescopic rod 19 is rotatably connected to the inner side of the front end of the extension frame 18 through a pin. The hydraulic telescopic rod 19 is connected to a hydraulic control cylinder through a hydraulic pipeline. An arc-shaped limiting plate 20 for blocking and limiting the inner wall of the limiting groove 15 is rotatably connected to the rear end of the extension frame 18 through a pin. The telescopic part of the rear end of the hydraulic telescopic rod 19 is rotatably connected to the outer side of the upper end of the arc-shaped limiting plate 20 through a pin.

[0024] Working Principle: In use, this utility model involves feeding the construction materials to be unloaded into the unloading hopper 16. When the materials are fed into the unloading hopper 16, they are discharged downwards into the limiting groove 15 due to gravity. As the materials enter the limiting groove 15, the arc-shaped limiting plate 20 blocks and limits the material from accumulating in the limiting groove 15 and the unloading hopper 16. When the materials accumulate in the limiting groove 15 and the unloading hopper 16, the hydraulic telescopic rod 19 is retracted. When the hydraulic telescopic rod 19 retracts, it drives... The arc-shaped limiting plate 20 swings open. When the arc-shaped limiting plate 20 swings open, the material accumulated inside the limiting groove 15 and the unloading hopper 16 can be discharged downwards into the opening groove 14 and the upper end of the conveyor belt 8. By controlling the degree of swing opening of the arc-shaped limiting plate 20, the amount of material discharged downwards can be controlled. At the same time, by controlling the start of the vibration motor 17, when the vibration motor 17 is turned on, the material inside the unloading hopper 16 will be vibrated to avoid the material accumulating inside the unloading hopper 16 and becoming blocked and difficult to discharge. This allows for the unloading of construction materials while facilitating the control of the amount of material discharged.

[0025] Simultaneously, when the material is discharged downwards into the opening trough 14 and onto the upper end of the conveyor belt 8, the reduction motor 3 is activated by control. When the reduction motor 3 is activated, it drives the first pulley 4 to rotate. When the first pulley 4 rotates, it drives the second pulley 5 to rotate via belt transmission. When the second pulley 5 rotates, it drives the transmission shaft 6 to rotate. When the transmission shaft 6 rotates, it drives the belt roller 7 to rotate. When the belt roller 7 rotates, it works with the upper support roller 10 and the lower support roller 12 to drive the conveyor belt 8 to rotate and convey. When the conveyor belt 8 rotates and conveys, the material at the upper end of the conveyor belt 8 can be conveyed outwards. The limiting side plate 13 limits the material conveyed at the upper end of the conveyor belt 8, thereby realizing the unloading of material while facilitating the outward conveying of the unloaded material.
