A dust-proof device for a cement mixer

Abstract

The invention belongs to the technical field of dustproof devices and particularly relates to a dustproof device for a cement mixing machine. The dustproof device comprises dustproof plates, driving arc strips and the like. The dustproof device is provided with a heavy threaded ring, an opening end of a cement stirring shell inclines downwards and upwards in the loading and filling processes of acement stirring joint, the heavy threaded ring rotates along two symmetrical spiral slots formed in a second fixed ring under the effect of gravity, the six driving arc strips drive the correspondingdustproof plates to rotate around a second column pin, and the loading or filling operation of the cement mixing machine can be finished; and when the cement mixing machine is used for normally stirring, the six driving arc strips drive the corresponding dustproof plates to rotate around the second column pin so as to close the opening end of the cement stirring shell, so that a dustproof mechanism is capable of preventing dust in the cement stirring shell from being discharged out during the normal stirring operation of the cement mixing machine.

Description

technical field [0001] The invention belongs to the technical field of dust-proof devices, in particular to a dust-proof device for a cement mixer. Background technique [0002] At present, the dust-proof device adopted by the existing cement mixer has a simple structure and a single function. When the cement mixer is in the process of mixing, due to the rotary motion of the cement mixer, the cement ash in the cement mixing shell will be quickly agitated, thereby As a result, there will be a lot of dust on the work site, and more dust will spread into the air, but dust is the enemy of human health, because dust can carry many bacteria, viruses and insect eggs flying around, it will be very likely of spreading diseases. Industrial dust and fiber dust can cause construction workers to suffer from various difficult-to-cure occupational diseases. Excessive dust at the work site can also cause environmental pollution, thereby affecting people's normal life and work, and inducing...

[0002] At present, the dust-proof device adopted by the existing cement mixer has a simple structure and a single function. When the cement mixer is in the process of mixing, due to the rotary motion of the cement mixer, the cement ash in the cement mixing shell will be quickly agitated, thereby As a result, there will be a lot of dust on the work site, and more dust will spread into the air, but dust is the enemy of human health, because dust can carry many bacteria, viruses and insect eggs flying around, it will be very likely spread of diseases

Industrial dust and fiber dust can cause construction workers to suffer from various difficult-to-cure occupational diseases. Excessive dust at the work site can also cause environmental pollution, thereby affecting people's normal life and work, and inducing human respiratory diseases. Dust is also very harmful to engineering computers. Too much dust may block the CPU fan and stop the fan, causing the CPU to overheat and burn. It will also affect the contact between boards and cards, and may also cause corrosion of the circuit board. This will cause great economic losses to enterprises, individuals and the country, so it is very necessary to design a dust-proof device for cement mixers
