AI Technical Summary
During the maintenance of traditional cement board pavement, the old cement board material must be transported to the crushing plant and then returned to the site for use, resulting in increased fuel costs and environmental pollution. At the same time, the walking cement block crusher is prone to uneven heights when paving, and requires manual or mechanical Leveling, increasing workload and cost.
Design a walking cement block crusher flattening mechanism, including installing a flattening mechanism on the back of the bottom of the crusher body, using a hydraulic motor or a motor-driven active sprocket and passive sprocket to crush cement through a tripod and spiral blade. Evenly spread the blocks.
The device can directly and evenly spread the broken cement blocks on site, saving additional leveling work, saving manpower and material resources, and improving construction efficiency.

Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of highway construction equipment, in particular to a walking type cement block crusher flattening mechanism. Background Art
[0002] With the development of highway construction and the increase in traffic volume in my country, more and more cement slab pavements have entered the maintenance period and need to be rebuilt. One of the traditional ways to deal with damaged cement slab pavements is to use a pickaxe to crush the old pavement cement slab material into large blocks of cement concrete and then send it to the crushing plant. After crushing, it is transported back to the site as gravel material. Its advantage is that it can effectively utilize the cement slab crushed material, and the particle size of the cement slab crushed material can be adjusted according to requirements. However, since it needs to rely on vehicles to transport it back and forth, it increases fuel costs and pollutes the environment. The use of a walking cement block crusher can directly crush cement blocks on site into a particle size that can directly serve as a base layer, solving the above problems. However, when the walking cement block crusher lays the cement blocks on the road, it is inevitable that there will be unevenness, which requires manual or mechanical leveling at the rear, increasing the workload and cost. Utility Model Content
