Dust prevention device used on cement mixer

Abstract

The invention belongs to the technical field of dust prevention devices, and particularly relates to a dust prevention device used on a cement mixer. The dust prevention device comprises a dust prevention plate, a first gear and the like. The dust prevention device is provided with a heavy thread ring. When the cement mixer carries out charging and loading, the opening end of a cement mixing shellcan be inclined downwards and upwards, at that time, the heavy thread ring does rotational movement along two symmetric spiral grooves formed in a second fixing ring under the action of gravity, sixdust prevention plates can do rotational movement around the axis of a first fixing shaft, and the cement mixer can complete the charging or loading work. When the cement mixer does normal mixing work, at that time, the six dust prevention plates do rotational movement around the axis of the first fixing shaft, the purpose of closing the opening end of the cement mixing shell is achieved, and therefore the purpose that when the cement mixer does normal mixing work, a dust prevention mechanism can play a role in preventing dust in the cement mixing shell from going out is achieved.

Description

technical field [0001] The invention belongs to the technical field of dust-proof devices, in particular to a dust-proof device used on 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 indu...

[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 the computer. 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 the boards and cards, and may cause corrosion of the circuit board. It will cause great economic losses to enterprises, individuals and the country, so it is very necessary to design a dust-proof device used on cement mixers
