Embodiment 1

[0016] see Figures 1 to 3 As shown, a kind of asphalt laying device based on municipal road engineering involved in this embodiment includes a fuselage 2 provided with a push handle 1, and the bottom of the fuselage 2 has a planar bottom plate 3, on which the fuselage 2 A hollow feed shaft 4 extending vertically up and down is provided, the lower end of the hollow feed shaft 4 protrudes from the bottom plate 3, and the upper end is provided with a feed unit 5, the hollow feed shaft 4 is rotatably connected with a disc 6, The upper end surface of the disc 6 is provided with a ring gear 7 coaxial with the ring gear 7, and a gear 8 is meshed with the ring gear 7. The gear 8 is provided with a first motor 9 for controlling its rotation. The first motor 9 is located on the On the fuselage 2, the lower end surface of the disc 6 is provided with a plurality of pressure roller assemblies 10 arranged in an annular array at equal intervals around its axis. , an outer bracket 102 away ...

Embodiment 2

[0021] see Figures 1 to 3 As shown, a kind of asphalt laying device based on municipal road engineering involved in this embodiment, on the basis of Embodiment 1, it is further set that the side of the feed bin 51 is provided with a compartment surrounding it 54, the compartment 54 is provided with an electric heating wire 55 arranged on the feed bin 51 in the form of a spiral disk.

[0022] In this embodiment, through the arrangement of the compartment 54 and the electric heating wire 55, it is used to provide heat supply and heat preservation to the feed bin 51, so that the inside of the feed bin 51 is heated up, and the asphalt mixed with sand and gravel is prevented from being heated by the outside. Solidification occurs due to lower temperature, resulting in poor transportation.

Embodiment 3

[0024] see Figures 1 to 3 As shown, a kind of asphalt laying device based on municipal road engineering involved in this embodiment, on the basis of Embodiments 1 and 2, it is further set that, the hollow feed shaft 4 is connected in series with a close to the feed Solenoid valve 14 of unit 5.

[0025] In this embodiment, the solenoid valve 14 is used to control the on-off of the hollow feed shaft 4 .

Abstract

The invention discloses an asphalt laying device based on municipal road engineering, which comprises a machine body, the bottom of the machine body is provided with a bottom plate, the machine body is provided with a hollow feeding shaft, the lower end of the hollow feeding shaft extends out of the bottom plate, the upper end of the hollow feeding shaft is provided with a feeding unit, the hollow feeding shaft is rotatably connected with a disc, the upper end face of the disc is provided with a gear ring, and the gear ring is engaged with a gear. A first motor is arranged on the gear, a plurality of compression roller assemblies which are distributed in an annular array at equal intervals around the axis of the disc are arranged on the lower end face of the disc, each compression roller assembly is composed of an inner support, an outer support and a compression roller shaft, a floating assembly is arranged between every two adjacent compression roller assemblies, and each floating assembly is composed of a follow-up pressing block, a bearing plate and a compression spring; a first universal ball is arranged on the inner side of the floating assembly, and a second universal ball is arranged on the outer side of the floating assembly. The asphalt paving device is suitable for local repair of the road, flat in press fit, high in construction efficiency, complete in overall function and high in practicability.

Description

technical field [0001] The invention relates to the technical field of mechanical equipment, more specifically, it relates to an asphalt laying device based on municipal road engineering. Background technique [0002] During the road paving process of asphalt mixed with gravel, the asphalt mixed with gravel needs to be poured on the road to be paved first, then artificially pre-pressed, and finally rolled repeatedly by rolling equipment, and the asphalt road is completed after solidification layout. This type of laying method is traditional and efficient, but it is not suitable for partial repair of municipal roads, resulting in partial repair operations that are mostly done manually, which is cumbersome and time-consuming. There is no special small rolling equipment, and the pressing is not smooth. bad. Accordingly, the present invention proposes an asphalt laying device based on municipal road engineering. Contents of the invention [0003] The purpose of the present ...
