Folding unloading and dust suppression device of road cleaning special vehicle and road cleaning special vehicle

Abstract

The invention discloses a folding unloading and dust suppression device of a road cleaning special vehicle and the road cleaning special vehicle. The folding unloading and dust suppression device of the road cleaning special vehicle comprises a tarpaulin, a framework, a protective plate and a driving device; and the folding unloading and dust suppression device of the road cleaning special vehiclecan physically isolate unloading areas in the unloading process of the road cleaning special vehicle and can effectively inhibit a dust flying phenomenon during unloading dry powder garbage. According to the folding unloading and dust suppression device of the road cleaning special vehicle, in a non-working state, the framework and the external protective plate can be all folded by using one setof connecting rod mechanism; the highly weather resistant tarpaulin fixed on the framework can be all folded at the tail part of the whole vehicle; and therefore, it can be guaranteed that the tarpaulin cannot be blown out by airflow during running. Before materials need to be unloaded, the driving device pushes the connecting rod mechanism to be unfolded, and meanwhile, the protective plate is opened, and the whole folding type unloading and dust suppression device completely seals a garbage pouring area to achieve a dust suppression effect. The folding unloading and dust suppression device of the road cleaning special vehicle has the advantages of lightweight and compact structure and no secondary pollution; and a common dry powder type garbage unloading flying dust problem is directly and effectively solved.

Description

technical field [0001] The invention belongs to the technical field of special-purpose vehicles, and in particular relates to a folding dust suppression device for a special vehicle for road cleaning and a special vehicle for road cleaning. Background technique [0002] With the continuous development and popularization of the mechanization of sanitation work in our country, special vehicles for road cleaning are currently widely used in cleaning operations on urban roads, expressways, squares and other occasions. [0003] The general road cleaning special vehicle drives a fan through the power system to generate a certain negative pressure in the garbage bin, and finally connects the suction nozzle close to the ground through the pipeline to suck the ground garbage into the garbage bin cabin, and then through inertial dust removal, dust removal filter Dust removal methods such as drums keep the particles in the airflow with the smallest PM2.5 level in the dustbin cabin, and...

Problems solved by technology

[0004] For cold periods and water-scarce areas, the cleaning process often does not use a large amount of water or even uses an anhydrous operation mode for cleaning. Therefore, the garbage left in the garbage bin often has a low water content and a large amount of dry powdery dust is accumulated. When unloading, gravel and other garbage particles, with the rapid dumping of a large amount of garbage, it will cause an instant and severe dust phenomenon, commonly known as "dust explosion", which will cause serious secondary pollution to the environmental sanitation near the unloading site

[0005] In order to prevent the phenomenon of "dust explosion", a dust suppression device is usually installed at the back door of the garbage bin body. A common dust suppression device is to install a high-pressure water mist nozzle on the edge of the rear door of the garbage bin. Water is used for dust suppression, but this method cannot effectively discharge enough water mist for dust suppression at the moment of "dust explosion", and the effect is not good. On the other hand, it is not suitable for some working conditions that require no water operation, and the applicability is not enough. wide, and the water mist and fine dust will adsorb each other to become mud, resulting in secondary pollution

The other is to directly wrap the unloading part of the rear door with a cover, but on the one hand, this structure will greatly increase the size of the vehicle and affect the mobility of the vehicle; Because of the reciprocating swing of the airflow, it will seriously affect the driving safety. Therefore, this kind of structure is rarely seen now.
