Road asphalt paving head and paving device with head

Abstract

The invention discloses a road asphalt paving head and a paving device with the head. The paving head comprises a double-shaft motor, a first transmission shaft is fixedly arranged on the double-shaftmotor, three sets of adjusting gears are movably engaged in a transmission chain, the outer side of a thread rod is provided with an outer nut in a threaded manner, a push rod is fixedly arranged onthe outer nut, the push rod is in abut joint with a first base plate, a second base plate and a third base plate, an extension rod is fixedly arranged on the first base plate, a compressing roller ismovably arranged on the rotating shaft, an ironing plate is fixedly arranged on the second base plate, and rake teeth are fixedly arranged on the third base plate. The road asphalt paving head is provided with the three paving structures of the rake teeth with the height capable of being independently adjusted, the ironing plate and the compressing roller, a stirring structure capable of preventing hardening is arranged in a hopper, the paving effect is effectively improved, the invention further discloses a paving device based on the road asphalt paving head, use is convenient, and the deviceis quite worth popularization.

Description

technical field [0001] The invention relates to the technical field of road paving devices, in particular to a road asphalt paving head and paving equipment thereof. Background technique [0002] In the prior art, an asphalt paving device for building construction with the application number "201811316792.8" includes a fixed base plate, a control box is fixed on the top outer wall of the fixed base plate by bolts, and one side of the inner wall of the control box passes The processor is fixed by bolts, four first hydraulic cylinders are fixed by bolts on the top outer wall of the fixed bottom plate, and the top of the first hydraulic cylinders is fixed with a mounting plate by bolts, and the top of the mounting plate is provided with cooling holes. The asphalt paving device for building construction can stir the raw materials in the material box body and scrape the inner wall of the material box body to prevent the raw materials from agglomerating and sticking to the inner w...

AI Technical Summary

Problems solved by technology

[0003] However, there are still relatively obvious defects in its use: 1. The above-mentioned device only realizes asphalt paving by rake teeth, and lacks a device for timely screed and compaction of asphalt, which affects the smoothness of asphalt and has limited effect ; 2. The above-mentioned device uses an independent motor to stir the material in the material box, and uses the first hydraulic cylinder and the second hydraulic cylinder to realize the asphalt paving of different thicknesses, which requires more power devices, not only the structure is complex, And it will increase the assembly cost and use cost
