Description

Technical Field

[0001] The utility model relates to a dust-proof loading funnel, in particular to a tire-mobile spray dust-proof loading funnel. Background Art

[0002] With the improvement of environmental protection requirements in port terminals, the old-fashioned unloading funnels can no longer meet the current environmental protection requirements due to the dust generated during the loading and unloading of materials, causing environmental pollution. Port terminals at home and abroad are eager to upgrade their equipment to meet environmental protection requirements. The tire-mobile spray dust removal funnel is suitable for the loading and unloading operations of materials such as coal and ore that have low requirements for water content.

[0003] After retrieval, the patent: A loading funnel with a dust removal system (CN202310154464.7), includes a funnel frame and a funnel body erected on the funnel frame. At the discharge port at the bottom of the funnel body, three discharge funnels are connected side by side. Below the three discharge funnels, a telescopic sealed carriage cover is connected. A telescopic material pipe is connected between the connection hole and the funnel mouth. The feeding port of the funnel body is connected with a feeding dust-proof mechanism communicating with the connection hole. On the upper layer frame surrounding the feeding dust-proof mechanism, a dust removal device for dust removal of the feeding dust-proof mechanism is connected. The dust removal device is communicated with the telescopic material pipe through a connecting pipe. At the top of the funnel frame, an anti-collision mechanism for preventing the gantry grab from colliding is connected. At the bottom of the lower layer frame, a guiding device for positioning the truck loading is connected. The output end of the guiding device is connected with the input end of the control device. Although the above structure also has dust prevention and adsorbs through the air duct, there is no dust prevention treatment at the discharge port, and dust may splash during unloading, affecting the environment.

[0004] In view of the above defects, the designer actively conducts research and innovation in order to create a dust-proof loading funnel with a new structure, making it more valuable in industrial utilization. Summary of the Utility Model
