Description

Technical Field

[0001] The utility model relates to the technical field of port machinery and equipment, in particular to a dustproof tonnage bucket. Background Art

[0002] During port operations, ton buckets, as a common means of transportation, often need to work in a high-dust environment. In the existing technology, dust-proof ton buckets are equipped with a flexible plastic plate between the storage hopper and the chute. However, the dust-proof effect of the existing technology is poor. After the material enters the chute from the ton bucket, a large amount of dust will be emitted during the flow and impact of the material itself. The large amount of dust not only causes cargo loss but also increases the cost of maintaining the ton bucket. At the same time, it also seriously endangers the health of the operators. Utility Model Content

[0003] The main purpose of the utility model is to provide a dustproof tonnage bucket, which aims to solve the technical problem of poor dustproof effect of the dustproof tonnage bucket in the existing technology and further improve the dustproof effect of the dustproof tonnage bucket.

Furthermore, the dust suction mechanism of the present invention is an air control component and a pressure relief duct arranged on the chute below the ton bucket.

[0048] The following content serves as an explanation of the working principle of the dust prevention process of this utility model:

[0049] Start the control box 6 to carry out manual bagging. After the manual bagging is completed at the lower part of the chute 4, the switch 611 is pulled by the pull rope, and then the control box 6 controls the first cylinder 311 to open the first hopper 31, and the material in the storage hopper 2 passes through the first material port 221 and is discharged from the first hopper 31. Thereafter, the control box 6 controls the second cylinder 321 to open the second hopper 32, and the material in the storage hopper 2 passes through the second hopper 32 from the second material port 222 and is discharged into the chute 4. The dust suction mechanism 5 operates the directional exhaust in the direction of the storage hopper 2, that is, the gas control valve 51 delivers gas to the pressure relief pipe 52 through the pressurized air duct 512, and the compressed gas adsorbs the dust floating in the chute 4, and the gas guides the dust back to the inlet 21 of the storage hopper 2 for refilling and bagging cycle operation; the material bagged from the bottom of the chute 4 is collected normally.

[0050] The key to the present invention is that during operation, workers cover the outlet 42 below the chute with a woven bag. In this process, a large amount of material dust will be generated at the chute 4 due to the flow and impact of the material. A dust collection mechanism 5 is used. Specifically, the air control component 51 transports gas, and the gas absorbs the material dust. The material dust is then transported back to the storage hopper 2 in the dust-proof tonnage hopper for re-filling through the pressure relief conduit 52, thereby reducing dust flying and cargo damage.
