Problems solved by technology

[0005] 1. The material cannot be uniformly and fully discharged from the feeding port. For the material remaining in the mixing chamber, it will cause waste of material and it is not easy to clean up.
[0006] 2. The material finally falls to the ground through only one outlet, and the material is not evenly discharged.
[0007] 3. The paving slab moves back and forth along the width of the pavement. If there is too much material, the material will overflow from both sides of the paving slab or scatter outside the paving width of the paving slab. It is beyond the paving range of the paving slab. It is necessary to check the overflow or scattering The materials are cleaned up, which wastes manpower and reduces the construction efficiency

Embodiment 1

[0040] A kind of road asphalt paving equipment that the present invention proposes, as figure 1 As shown, it includes a lower hopper 1, a frame 33, a headstock 34, a lower material mechanism, a flow divider 7 and a push frame 8. The lower hopper 1 is a rotary structure, and the inner diameter of the lower hopper 1 gradually decreases from top to bottom. 1 is arranged on the frame 33, and the frame 33 is arranged on the headstock 34.

[0041] Such as image 3 As shown, the unloading mechanism includes a bracket a2, a motor a3, a connecting platform a4, a deflection shaft 5 and a screw blade 6, the bracket a2 is arranged on the unloading hopper 1, the motor a3 is arranged on the bracket a2, and the motor a3 is driven and connected to the connecting platform a4. The connecting table a4 is connected with the deflection shaft 5, the deflection shaft 5 is set eccentrically with the central axis of the lower hopper 1, the screw blade 6 is set on the deflection shaft 5, the outer dia...

Embodiment 2

[0050] A kind of road asphalt paving equipment that the present invention proposes, compared with embodiment one, in the present embodiment, as figure 1 , figure 2 with Figure 4 As shown, there is an inverted Y-shaped channel inside the inverted Y-shaped structure. The inverted Y-shaped channel is composed of a vertical channel and two symmetrically arranged inclined channels. The top of the inclined channel communicates with the bottom end of the vertical channel. The connection of the inclined channel on the outside is defined as the external connection.

[0051] Such as Image 6 As shown, the diverter 7 is provided with a plurality of blocking mechanisms, the blocking mechanism includes a baffle 30, and is used to drive the baffle 30 to move so that the baffle 30 blocks the external communication or moves away from the external communication. drive mechanism 31.

[0052] In this embodiment, the baffle plate 30 can be driven to move back and forth by the mobile drive m...

Embodiment 3

[0054] A kind of road asphalt paving equipment that the present invention proposes, compares embodiment one or embodiment two, in this embodiment, if figure 2 with Figure 4 As shown, the pushing frame 8 is a Z-shaped plate structure, including a mounting plate part, a diverter plate part and a pressing plate part connected in sequence, and the diverter plate part is used to evenly spread the mixture falling from the diverter 7, The pressing plate part is arranged horizontally, the pressing plate part is lower than the mounting plate part, and the pressing plate part is used for pressing down the mixture. The diverter plate part is a wavy plate-shaped structure, and the wave-shaped protruding part faces the bottom of the discharge end of the lowest inverted Y-shaped pipe structure. Evenly stacked under multiple discharge ends, the protruding part of the splitter plate with a wave-shaped plate structure can face the accumulation place, spread the mixture evenly on both sides,...

Abstract

The invention relates to the field of road construction, in particular to road asphalt paving equipment and a method thereof. The device comprises a discharging hopper, a machine frame, a machine head, a discharging mechanism, a flow divider and a pushing and pressing frame, the discharging hopper is of a rotary structure, the inner diameter of the discharging hopper is gradually reduced from top to bottom, the discharging hopper is arranged on the machine frame, and the machine frame is arranged on the machine head; the discharging mechanism comprises a support a, a motor a, a connecting table a, a deflection shaft and a spiral blade, the support a is arranged on the discharging hopper, the motor a is in driving connection with the connecting table a, the connecting table a is connected with the deflection shaft, the deflection shaft and a center shaft of the discharging hopper are eccentrically arranged, the spiral blade is arranged on the deflection shaft, and the outer diameter of the spiral blade is gradually reduced from top to bottom. The spiral blade is eccentrically arranged on the inner side of the blanking hopper; a driving device used for driving the flow divider to vibrate front and back and driving the pushing frame to push the materials forwards in a circulating mode, then move backwards and press the materials downwards is arranged on the machine frame. According to the invention, materials can be fully and uniformly discharged and uniformly and efficiently paved.

Description

technical field [0001] The invention relates to the field of road construction, in particular to a road asphalt paving equipment and a method thereof. Background technique [0002] During road construction, if an asphalt road needs to be built, asphalt paving equipment is required to spread the mixture of asphalt and mineral aggregate on the road surface, and then use a road roller to compact and flatten the paved mixture. [0003] Chinese Patent Publication No. CN111676782A discloses a road engineering pavement asphalt paving equipment, including a base, a pressure roller is installed on the rear end of the lower surface of the base, and a vibrating motor is installed on the upper surface of the base near the side of the push handle. The upper surface of the base is located on the front side of the vibrating motor, and a stirring bin is installed. The lower end of the front surface of the stirring bin is connected with a discharge pipe, and the front end of the base is prov...
