Description

A filter and dust suction structure for an electric self-priming cleaning vehicle

Technical Field

The invention relates to, in particular to, a filtering and dust collecting structure of an electric self-priming cleaning vehicle.

Background technique

As cities continue to expand, the flow of people and vehicles increases dramatically, and there is more and more garbage and dust on the roads. At present, there are many types of sanitation cleaning vehicles used for road cleaning, including large fuel-powered road cleaning vehicles and small road cleaning vehicles. The common problems of large fuel-powered road cleaning vehicles are: poor economy, high emissions, and failure to meet increasingly stringent environmental protection requirements; the large size leads to dead corners during road cleaning, and the sides and corners of the road cannot be cleaned; dust will be raised during cleaning and garbage dumping, causing secondary pollution. Small road cleaning vehicles are favored by sanitation departments because of their mobility and thorough cleaning. However, the existing small road cleaning vehicles cannot achieve automatic filtering and dust collection and automatic garbage sorting. There are many problems such as secondary dust generated by manual cleaning operations, manual picking and sorting, and time-consuming and labor-intensive operations.

Summary of the invention

The technical problem to be solved by the present invention is to provide a filtering and dust collection structure for an electric self-priming cleaning vehicle that can realize automatic filtering and dust collection and automatic garbage classification, avoid secondary dust generation and manual picking and classification, and save time and effort.

To solve the above problems, the present invention adopts the following technical solutions:

A filtering and dust collecting structure of an electric self-priming cleaning vehicle comprises a frame, a vehicle bottom dust collecting device and a mounting frame are arranged on the frame, and a dust collecting fan and a filter bag are installed on the mounting frame;

The special feature is that a vertically arranged trash bin is fixed at the rear end of the frame, and a main dust suction pipe is arranged in the trash bin. The main dust suction pipe is an inverted U-shape, and both ends of the main dust suction pipe are sealed and pass through the trash bin respectively, and are connected to the two circular outlets of the undercar dust suction device through hoses. A main suction port with a downward opening is arranged in the middle of the main dust suction pipe;

An air inlet is arranged below the main suction port on the bottom plate of the trash bin and is connected to the air duct inlet arranged on the mounting frame; a semi-spherical filter is arranged at the air inlet in the trash bin to filter the dust sucked into the dust suction fan.

As a further preference, a filter bag is fixed to the main suction port in the middle of the main dust suction pipe by a clamping ring so as to filter the dust sucked into the main dust suction pipe.

As a further preference, corrugated hoses are respectively connected to both ends of the main dust suction pipe, and lower gates rotatably inserted into the corrugated hoses are respectively provided in the middle of the corrugated hoses corresponding to both sides of the trash can to control the on and off of the main dust suction pipe.

As a further preference, an auxiliary dust suction pipe is installed at the upper end of the trash can. One end of the auxiliary dust suction pipe is located in the trash can and is provided with an auxiliary suction port opening downward. The other end of the auxiliary dust suction pipe is led out of the trash can and is connected to a quick connector through a corrugated rubber hose for connecting an extension pipe to clean dust at a distance.

As a further preference, a filter bag is fixed to the auxiliary suction port by a clamping ring so as to filter the dust sucked in by the auxiliary dust suction pipe.

As a further preference, an upper gate plate which can slide in the longitudinal direction is provided in the middle of the corrugated rubber hose corresponding to the other end of the auxiliary dust suction pipe on the outside of the garbage bin, so as to control the opening and closing of the auxiliary dust suction pipe.

As a further preference, a door is hinged on one side of the rear end of the trash bin to achieve sealing of the trash bin.

As a further preference, a pull-out lower drawer is provided on the frame below the trash bin via a slideway for collecting the trash sucked into the trash bin.

As a further preference, a tightening device is provided on the frame at the bottom surface of the slideway, and after the tightening device is activated, the lower drawer box can be lifted up so that the lower drawer box is pressed against the bottom surface of the trash bin to achieve sealing.

The beneficial effects of the present invention are as follows: since the main dust suction pipe is an inverted U-shape and both ends are sealed and passed through the garbage bin, and are correspondingly connected to the two circular outlets of the under-vehicle dust suction device through hoses, the dust sucked in by the under-vehicle dust suction device can be discharged into the garbage bin through the main dust suction pipe; and filtered and separated by a semi-spherical filter net arranged at the air inlet in the garbage bin, finer dust is sucked into the filter bag by the dust suction fan, and larger particles and garbage remain in the garbage bin, which can realize automatic filtering and dust suction and automatic garbage sorting, avoid the generation of secondary dust and manual picking and sorting, and save time and effort.

The lower end of the piston rod of the electric push rod 12 is connected to one end of one of the tightening shafts 14 through a crank 25, so that after the electric push rod 12 is extended, it can drive the two tightening shafts 14 to rotate simultaneously to lift the lower drawer 15. Each tightening shaft 14 is formed by welding two long rods of different lengths in parallel, wherein the longer long rod is hinged on the bottom of the slideway, and after rotation, the lower drawer 15 is lifted up through the shorter long rod.

As shown in FIG6 , the undercar dust suction device 17 includes a fixing frame 32 fixed to the bottom of the frame 1, an electric linear guide 31 and a polished rod 30 are installed on the fixing frame 32, a dust suction shell 35 is connected to the polished rod 30 through a bracket 37, one end of the bracket 37 is mounted on the polished rod 30 through a sliding sleeve 28 and is connected to the slider of the electric linear guide 31, and is used to drive the dust suction shell 35 to reciprocate laterally under the drive of the electric linear guide 31; a rectangular suction port is provided on the bottom surface of the dust suction shell 35 and a sealing strip 36 is provided around the rectangular suction port, and two circular outlets 34 respectively connected to the rectangular suction port are arranged in parallel on the dust suction shell 35, which are used to connect a hose to discharge the sucked dust into the trash can; directional wheels are symmetrically installed at the rear bottom of the dust suction shell 35, and universal wheels 27 are symmetrically installed at the front end of the dust suction shell 35, which are used to support the dust suction shell 35 during operation. Side guide wheels 38 are symmetrically arranged at the rear of both sides of the dust collecting housing 35, and the outer edges of the side guide wheels 38 protrude from the edges of both sides of the dust collecting housing 35 so as to reduce friction when working on the roadside by leaning against the curbstone. A lifting frame 29 is hinged on the fixed frame 32, and the lifting frame 29 is passed through by a crossbeam arranged on the bracket 37. An electric push rod 33 is connected to one end of the lifting frame 29, and the upper end of the electric push rod 33 is fixedly hinged on the frame, and is used to drive the bracket 37 and the dust collecting housing 35 to achieve lifting through the lifting frame 29.

During cleaning, the dust suction fan 21 is started to generate negative pressure in the trash bin, and the dust is sucked into the trash bin through the main dust suction pipe 4 and the undercar dust suction device 17. The sucked dust is filtered by the filter bag on the main suction port to filter out larger garbage such as leaves and cigarette butts. Then, it is filtered through the filter net 11 to filter out larger particles such as stones and fall into the lower drawer below. The filtered dust is sucked into the filter bag by the dust suction fan for re-filtration, and the dust filtered by the filter bag falls into the dust collection box 3.
