[0005] (2) Technical Solution

[0006] To solve the above technical problems, the utility model provides such a splash-proof device for a belt conveyor, which includes a conveyor main body and a material blocking component. The conveyor main body is distributed in a high-low staggered layer, and the material blocking component is installed on the conveyor main body with a lower height; the material blocking component includes a shielding frame, a movable flap, a fan, and a wind hood. The shielding frame is in a U-shaped structure, and a movable flap is movably installed on one side corresponding to the conveying direction of the conveyor main body.

An exhaust duct is connected above the fan; the wind hood is movably arranged inside the shielding frame, and a hose is connected above the wind hood, and the other end of the hose is connected to the fan. Thanks to the setting of the material blocking component, the sand and gravel aggregates moving on the conveyor main body can be protected to avoid the splashing of the falling sand and gravel aggregates, making the sand and gravel aggregates more concentrated. By arranging the wind hood inside the shielding frame, the adsorption force generated by the fan is transmitted to the wind hood, and the wind hood adsorbs the dust raised inside the shielding frame and transmits it to the exhaust duct through the hose, avoiding the flying of dust and effectively improving the environmental sanitation on site.

[0013] (3) Beneficial effects

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

[0015] Benefiting from the setting of the material blocking assembly, the present utility model can protect the sand and gravel aggregate moving on the main body of the conveyor, prevent the falling sand and gravel aggregate from splashing everywhere, and make the sand and gravel aggregate more concentrated. By arranging an air hood inside the shielding frame, the adsorption force generated by the fan is transmitted to the air hood, and the air hood adsorbs the dust raised inside the shielding frame and transmits it to the exhaust duct through a hose, avoiding dust flying, effectively improving the environmental sanitation on site. The air hood itself is movably arranged. When the telescopic cylinder starts to expand and contract, it drives the driving plate to reciprocate horizontally inside the shielding frame. During the movement of the driving plate, the tooth groove on its surface fits and drives the driving gear, and the driving gear rotates under force, and then the driving shaft rotates. The driving shaft drives the air hood to swing through the connecting block. As the telescopic cylinder continuously expands and contracts, the air hood swings inside the shielding frame under force, which can effectively improve the dust adsorption effect. The principle is simple and easy to implement, and can be widely promoted. Description of the drawings

[0023] This specific embodiment is a splash-proof device for a belt conveyor, and its structural schematic diagram is as shown in Figure 1 shown, including a conveyor main body 1 and a material baffle assembly 2. The conveyor main body 1 is distributed in a high-low staggered layer, and the material baffle assembly 2 is installed on the conveyor main body with a lower height;

[0024] Referring to Figure 2 , Figure 3, the material baffle assembly 2 includes a shielding frame 9, a movable flap 8, a fan 4 and a wind hood 10. The shielding frame 9 is in a U-shaped structure, and a movable flap 8 is movably installed on one side corresponding to the conveying direction of the conveyor main body 1. The fan 4 is fixed on the upper surface of the shielding frame 9. The wind hood 10 is arranged at an interval from the inner side of the shielding frame 9. An exhaust duct 3 is connected above the fan 4. The wind hood 10 is movably arranged inside the shielding frame 9. A hose is connected above the wind hood 10, and the other end of the hose is connected to the fan 4. A motor is fixedly installed on the outer wall of the shielding frame 9. A rotating shaft 6 is rotatably installed at the inner top end of the shielding frame 9. The rotating shaft 6 is connected to the output shaft of the motor. A connecting pipe 7 is fixedly sleeved outside the rotating shaft 6. The movable flap 8 is fixedly connected to the outer wall of the connecting pipe 7. A telescopic cylinder 5 is fixedly installed on the outer wall of the shielding frame 9. The telescopic cylinder 5 is horizontally arranged, and its telescopic end penetrates into the shielding frame 9.

[0025] Refer to Figure 3 , Figure 4 , the telescopic end of the telescopic cylinder 5 is fixedly connected with a driving plate 12. The driving plate 12 is horizontally arranged inside the shielding frame 9. A driving gear 16 is rotatably arranged below the driving plate 12. The surface of the driving plate 12 in contact with the gear has a tooth groove 13. The driving gear 16 is adapted to the tooth groove 13. A driving shaft 14 is fixedly penetrated inside the driving gear 16. The two ends of the driving shaft 14 are respectively rotatably connected to the conveyor main body 1. The driving shaft 14 and the driving gear 16 are concentrically distributed. A connecting block 15 is fixedly connected to the bottom end surface of the driving shaft 14. The connecting block 15 is fixedly connected to the outer wall of the upper surface of the wind hood 10.

[0026] Working principle: When in use, when the conveyor main body 1 is conveying sand and gravel aggregates, the sand and gravel aggregates will fall at the staggered position. At this time, the material baffle assembly 2 intercepts the sand and gravel aggregates splashing during the falling process. The motor is started to drive the rotating shaft 6 to rotate. The connecting pipe 7 fixed to the rotating shaft 6 rotates synchronously. The movable flap 8 changes from a horizontal state to an inclined state approaching the shielding frame 9 in the reverse direction to shield the sand and gravel aggregates. The splashing sand and gravel aggregates are blocked by the inner side wall of the shielding frame 9. During the falling process of the sand and gravel aggregates, the fan 4 is started. Through the hose, the wind hood 10 has an adsorption force. The wind hood 10 adsorbs the dust raised by the sand and gravel aggregates inside the shielding frame 9. The telescopic cylinder 5 is started to expand and contract, driving the driving plate 12 to reciprocate horizontally inside the shielding frame 9. During the movement of the driving plate 12, the tooth groove 13 on its surface fits and drives the driving gear 16. The driving gear 16 is forced to rotate, and then the driving shaft 14 rotates. The driving shaft 14 drives the wind hood 10 to swing through the connecting block 15. As the telescopic cylinder 5 continuously expands and contracts, the wind hood 10 swings inside the shielding frame 9 under force. The adsorption force generated by the fan 4 is transmitted to the wind hood 10. The wind hood 10 adsorbs the raised dust inside the shielding frame 9 and transmits it to the exhaust duct 3 through the hose, avoiding dust flying and effectively improving the environmental hygiene on site. The fan 4 is a device for pumping and exhausting air in the prior art.
