Description

Technical Field

[0001] The invention belongs to the technical field of asphalt recovery, and in particular relates to a primary crushing device for asphalt recovery. Background Art

[0002] Road asphalt is asphalt used for paving roads. Asphalt-paved roads will cause damage, cracks or extrusion bulges after long-term use. In this case, the old asphalt needs to be recycled. Most asphalt recycling equipment digs up the old asphalt road surface and transports it back to the factory for centralized crushing. Although the old asphalt can be recycled, the efficiency is low and the recycling cost increases. In addition, the existing road asphalt recycling generally uses a crusher to crush the asphalt, and then relies on manual cleaning and recycling, which has the disadvantage of low cleaning and recycling efficiency. The crushing generates a lot of dust. When the crushed asphalt gravel is cleaned manually, it is easy to breathe the dust into the body, which is very harmful to the human body.

[0011] Preferably, a crushing and cleaning groove is provided in the middle of the mounting plate, and the crushing member and the cleaning frame are both movable through the crushing and cleaning groove, so as to facilitate crushing and cleaning of old asphalt on the road through the crushing and cleaning groove.

[0012] Among them, a storage box is also installed in the protection box. The storage box is arranged at the lower end of the pushing component. The storage box is a cavity structure with upper and lower openings. A control door is provided at the opening at the lower end of the storage box. The gravel in the cleaning frame is temporarily stored in the storage box. When the control door is opened, the gravel in the storage box falls out.

[0016] (2) The crushing parts and the cleaning frame work alternately. Each time the crushing parts are crushed, they are cleaned by the cleaning frame, which reduces the presence of gravel on the road and makes it easier for the crushing parts to directly impact and crush the old asphalt on the road.

[0017] (3) During the cleaning process, the cleaning driving plate can automatically push the gravel in the cleaning frame into the storage box by acting on the pushing component. When the cleaning driving plate is moved away, the elastic member can be adsorbed, causing the elastic member to be recessed into the pushing cavity, which is convenient for storing the gravel.

[0018] (4) During crushing and cleaning, the protective box can shield the splashing of dust and debris, and at the same time push the gas in the cavity into the pushing component. The gas mixed with dust is filtered through the filter tube and adsorbed into the elastic bag, reducing the discharge of dust and reducing the harm to the staff. BRIEF DESCRIPTION OF THE DRAWINGS

[0057] The slider 10 continues to move downward until it moves to the bottom of the chute 14, and the electromagnetic suction cup 29 absorbs the crushing piece 30. The slider 2 11 moves leftward to a position slightly left of the center of the chute 2 15. The pushing assembly 8 is in an expanded state under the action of the spring 38, and the gas in the pushing chamber 35 enters the pushing assembly 8. The elastic member 34 is recessed into the pushing chamber 35, and the control valve in the connecting pipe 36 is closed. The control valve in the filter pipe 47 is opened, and the gas mixed with dust is filtered by the filter pipe 47 and then absorbed into the elastic bag 37, thereby reducing the discharge of dust and facilitating the next cleaning of the crushed stone.

[0058] The slider 10 moves upward to drive the crushing member 30 to move upward, and the slider 2 11 continues to move to the left. The slider 10 moves to the middle of the chute 14, and the slider 2 11 moves to the leftmost end of the chute 2 15;

[0059] Slider 10 continues to move upward, and slider 2 11 moves to the right. During the movement, the cleaning frame 33 moves downward to fit the road surface and moves to the right. Slider 10 moves to the uppermost end of chute 14, and slider 2 11 is located at a position slightly to the right of the center of chute 2 15.

[0060] After the crushing and cleaning of the place, the staff pushes the protection box 1 again through the handrail 46 to move it to another road surface that needs to be crushed for crushing.

[0061] Although the embodiments of the present invention have been shown and described, it is understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents. In short, if those skilled in the art are inspired by them and design structural modes and embodiments similar to the technical solution without creativity without departing from the purpose of the present invention, they shall all fall within the scope of protection of the present invention.
