It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0020] Reference Figure 1-4 The utility model provides a chain conveyor dust prevention device, including a fixed frame 1, the internal rotation connection of the fixed frame 1 is two sprocket groups 8 distributed on the left and right, each sprocket group 8 includes a rotating rod and two sprockets distributed front and back, the two sprockets are fixedly connected by the rotating rod, the two sprockets distributed on the left and right are connected by a chain 10, a plurality of chain plates 9 are fixedly installed on the upper end of the chain 10, and a gap is left between two adjacent chain plates 9, the front end of the fixed frame 1 is fixedly connected to a motor 2, and the output shaft end of the motor 2 is fixedly connected to the sprocket group 8 on the left end; the upper and lower ends of the fixed frame 1 are respectively installed with a blowing assembly and a dust extraction assembly.

[0021] Through the cooperation of the blowing assembly and the dust extraction assembly, in the process of conveying goods from right to left, the dust and debris attached to the surface of the goods will be blown away by the blowing assembly and absorbed by the dust extraction assembly. At this time, the amount of dust and debris on the chain plate 9 and the surface of the goods can be reduced. When the goods are finally conveyed to the receiving equipment, the amount of dust and debris entering the receiving equipment is reduced, thereby reducing the probability of damage to the receiving equipment. At the same time, when the chain plate 9 rotates to the lower end of the chain 10 and passes through the dust extraction assembly, the dust extraction assembly can vacuum the surface of the chain plate 9 again, so that the chain plate 9 can circulate and transport the goods more cleanly.

[0022] Among them, the blowing assembly includes a support frame 6, a first connecting pipe 7, a diverter pipe 13, a nozzle 14, a second connecting pipe 12 and a fan 5. The support frame 6 is fixedly installed on the upper end of the fixed frame 1, and a diverter pipe 13 is arranged inside the support frame 6. The lower end of the diverter pipe 13 is fixedly connected to a plurality of nozzles 14. The upper end of the diverter pipe 13 is fixedly connected to the first connecting pipe 7, the first connecting pipe 7 passes through the support frame 6 upward and is slidably connected to the support frame 6, the lower end of the first connecting pipe 7 is fixedly connected to the second connecting pipe 12, the front end of the fixed frame 1 is fixedly connected to the fan 5, and the exhaust end of the fan 5 is fixedly connected to the second connecting pipe 12; the dust extraction assembly includes a dust collector 4 and a dust hood 11, the dust collection end of the dust collector 4 is fixedly connected to the dust hood 11, the dust hood 11 is located in the fixed frame 1 and at the bottom end of the chain plate 9.

[0023] Further, if Figure 1 As shown, the bottom end of the fixing frame 1 is fixedly connected with a supporting leg 3. Under the action of the supporting leg 3, the fixing frame 1 can be supported on the ground more stably.

[0024] Further, if Figure 2 As shown, the nozzle 14 gradually tilts downward from left to right, and the dust collecting hood 11 is located on the side facing the nozzle 14. When working, the gas blown out from the nozzle 14 can be blown to the chain plate 9 on the right side of the nozzle 14 and the goods, so that the dust and debris on the surface of the chain plate 9 on the right side of the nozzle 14 and the goods fall off, and pass through the gap between the two chain plates 9, fall into the dust collecting hood 11, and are finally absorbed and processed by the vacuum cleaner 4, thereby completing the dust cleaning operation.

[0025] Further, if Figure 4 As shown, sliding holes 15 are provided on both the front and rear end surfaces of the support frame 6, the shunt pipe 13 extends into the sliding hole 15 and is slidably connected to the sliding hole 15, the front and rear ends of the shunt pipe 13 are fixedly connected to the connecting block 16, the front and rear ends of the fixed frame 1 are fixedly connected to the electric telescopic rod 17 through the support seat, and the output end of the electric telescopic rod 17 is fixedly connected to the connecting block 16. The first connecting pipe 7 is a flexible and retractable hose. During operation, the electric telescopic rod 17 can drive the shunt pipe 13 to move up and down with the cooperation of the connecting block 16, and then drive the multiple nozzles 14 to move up and down, so that the nozzles 14 can be height-adjusted, so that it is convenient to use the overall equipment to clean the goods at different heights. In this process, since the second connecting pipe 12 is a flexible and retractable hose, it can ensure that the shunt pipe 13 and the first connecting pipe 7 can be smoothly adjusted in height.

[0026] Further, if Figure 2As shown, the dust hood 11 is provided with a first inclined surface and a second inclined surface, and two first inclined surfaces and second inclined surfaces are provided, which are respectively located at the front and rear sides and the left and right sides of the dust hood 11, and are gradually inclined downward from the outside to the inside. During operation, dust and debris falling into the dust hood 11 can enter the vacuum cleaner 4 more smoothly along the first inclined surface and the second inclined surface.

[0027] The working principle of this utility model:

[0028] When in use, the motor 2 drives the sprocket group 8 to rotate, and at the same time, with the cooperation of the chain 10, the chain plate 9 is driven to rotate. As the chain plate 9 rotates, the goods can be gradually transported from right to left. During the transportation process, the fan 5 and the vacuum cleaner 4 are in operation, and the wind brought by the fan 5 enters the shunt pipe 13 along the first connecting pipe 7 and the second connecting pipe 12, and is finally ejected from the multiple nozzles 14 at high speed to clean the surface of the goods and the upper end surface of the chain plate 9. The vacuum cleaner 4 is in operation, and the suction force generated can suck a large amount of dust and debris blown away into the vacuum cleaner 4 along the dust collecting hood 11. At this time, the amount of dust and debris on the surface of the chain plate 9 and the goods can be reduced. When the goods are finally transported to the receiving device, the amount of dust and debris entering the receiving device is reduced, thereby reducing the probability of damage to the receiving device. At the same time, when the chain plate 9 rotates to the lower end of the chain 10 and passes through the dust extraction component, the dust extraction component can again perform dust extraction on the surface of the chain plate 9, so that the chain plate 9 can circulate and transport the goods more cleanly.

[0029] Finally, it should be noted that the above are only preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
