[0029] like Figure 1-2 As shown, the present application provides a cement silo unloading and dust collecting device, including a unloading pipe 1 for fixedly connected to the unloading port of the cement silo, a dust collecting hood 2 is movably sleeved on the unloading pipe 1, the dust collecting hood 2 is connected to a telescopic hose 3, the telescopic hose 3 is connected to a dust collecting fan 4, a mounting seat 5 is fixedly provided on the unloading pipe 1, the dust collecting fan 4 is fixedly provided on the mounting seat 5, a lifting and adjusting component 6 for driving the dust collecting hood 2 to move up and down is provided on the unloading pipe 1, a buffer component 7 is provided in the dust collecting hood 2, and the buffer component 7 is used to buffer the cement falling from the unloading pipe 1. When in use, the unloading pipe 1 is fixedly connected to the unloading port of the cement silo, and the dust collecting fan 4 is connected to the existing The dust treatment equipment is connected, and the dust hood 2 is moved downward by the lifting and adjusting component 6 to reduce the distance between the dust hood 2 and the vehicle's cargo box, thereby reducing the diffusion space of cement dust. The cement falls from the discharge pipe 1 into the dust hood 2 and then falls from the buffer component 7 into the vehicle's cargo box. When the dust hood 2 moves downward, it drives the buffer component 7 to move downward, thereby reducing the drop of the cement, reducing the impact of the cement when it falls, and effectively reducing dust. At the same time, the dust collecting fan 4 extracts the dust in the dust hood 2 through the telescopic hose 3 to the dust treatment equipment for treatment, thereby effectively preventing dust from polluting the environment and preventing workers from inhaling dust and causing harm to their bodies.

[0030] like Figure 1-2As shown, the lifting and adjusting assembly 6 includes a lifting cylinder 61 and a pad 62. The lifting cylinder 61 is located between the mounting seat 5 and the dust hood 2. The fixed end of the lifting cylinder 61 is fixedly arranged on the mounting seat 5. The telescopic end of the lifting cylinder 61 is fixedly connected to the pad 62. The side of the pad 62 away from the lifting cylinder 61 is fixedly connected to the dust hood 2. The pad 62 is driven up and down by the lifting cylinder 61, thereby driving the dust hood 2 to move up and down. The telescopic end of the lifting cylinder 61 is welded to the top of the pad 62, and the bottom of the pad 62 is welded to the top of the dust hood 2. The pad 62 can increase the contact area between the dust hood 2 and the telescopic end of the lifting cylinder 61, thereby preventing the dust hood 2 from being directly subjected to excessive thrust or pulling force from the telescopic end of the lifting cylinder 61 and causing local damage.

[0031] like Figure 1-2 As shown, there are two lifting and adjusting components 6, and the two lifting and adjusting components 6 are symmetrically arranged, so that the dust hood 2 can move up and down more stably. After the cement is loaded, the lifting cylinder 61 drives the pad 62 to move up and drives the dust hood 2 to move up, so that the dust hood 2 leaves the covering range of the vehicle bucket, ensuring the normal departure of the vehicle after the cement is loaded.

[0032] like Figure 1-2 As shown, two telescopic hoses 3 are provided, and the two telescopic hoses 3 are symmetrically arranged. The two telescopic hoses 3 are respectively connected to dust collecting fans 4. The required number of dust collecting fans 4 can be selected to start according to actual needs, which can improve the dust collecting efficiency of the dust collecting hood 2.

[0033] like Figure 1-2 As shown, the buffer includes a buffer hopper 71 and a solenoid valve 72. The upper end of the buffer hopper 71 is fixedly connected to the inner top of the dust collecting hood 2. The solenoid valve 72 is arranged at the discharge port of the buffer hopper 71. Cement falls from the discharge port of the cement storage into the discharge pipe 1, and then falls into the buffer hopper 71. Then, the opening of the buffer hopper 71 is controlled by the solenoid valve 72 to control the loading speed of the cement. The buffer hopper 71 can temporarily store the cement falling from the discharge pipe 1 and play a buffering role on the cement.

[0034] like Figure 1-2 As shown, an air distribution plate 8 is fixedly provided in the dust collecting hood 2, and the buffer lower hopper 71 passes through the air distribution plate 8. A plurality of ventilation holes are evenly arranged on the air distribution plate 8. The air distribution plate 8 is used to equalize the suction force of the dust collecting fan 4 to improve the dust collecting effect.

[0035] like Figure 2 and Figure 3As shown, a conical distribution plate 9 is provided in the dust collecting hood 2, and the conical distribution plate 9 is detachably connected to the buffer lower hopper 71, so as to facilitate the replacement of the worn conical distribution plate 9. The conical distribution plate 9 is located directly below the buffer lower hopper 71, and a through opening 91 is provided on the conical distribution plate 9. The diameter of the through opening 91 is smaller than the diameter of the discharge port of the buffer lower hopper 71. Cement falls from the discharge port of the buffer lower hopper 71 and passes through the conical distribution plate 9. Part of the cement falls from the through opening 91 of the conical distribution plate 9, and part of the cement falls from the surrounding areas of the conical distribution plate 9, so as to prevent the cement from accumulating in the middle of the vehicle bucket and affecting the loading effect.

[0036] like Figure 2 and Figure 3 As shown, a plurality of screws 10 are fixedly provided on the top of the conical distribution plate 9, and a connecting piece 711 is fixedly provided on the peripheral side of the discharge port of the buffer discharge hopper 71. A through hole compatible with the screw 10 is provided on the connecting piece 711, and the upper end of the screw 10 passes through the through hole. A limiting ring 101 and a locking nut 102 are provided on the screw 10. The limiting ring 101 is fixed on the screw 10 and is located at the bottom of the connecting piece 711, and the locking nut 102 is threadedly connected to the screw 10 and is located at the top of the connecting piece 711. When the conical distribution plate 9 needs to be replaced, the locking nut 102 is rotated to separate the locking nut 102 from the screw 10, and then the conical distribution plate 9 is pulled downward to separate the screw 10 from the through hole on the connecting piece 711. It is simple and convenient. In this embodiment, four screws 10 are provided, and the four screws 10 are evenly arranged around the through hole 91 of the conical distribution plate 9, so that the conical distribution plate 9 can be installed stably.

[0037] like Figure 2 and Figure 3 As shown, a wear-resistant layer (not shown in the figure) is provided on the top of the conical distribution plate 9. The provision of the wear-resistant layer prolongs the service life of the conical distribution plate 9 and reduces the replacement frequency of the conical distribution plate 9.

[0038] The above are only preferred embodiments of the present application and are not intended to limit the present application. For those skilled in the art, the present application may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
