Problems solved by technology

First of all, after a large amount of land is piled with construction waste, it will reduce the quality of the soil and reduce the production capacity of the soil; the construction waste is piled in the air, which affects the air quality, and some dust particles will be suspended in the air, which is harmful to human health; Medium and long-term accumulation is the harmful substances of construction waste infiltrating into the groundwater and polluting the water environment; if construction waste is piled up in the city, it is not good for the urban environment and aesthetics; some accidents may happen
[0003] By recycling construction waste, screening and crushing, concrete blocks can be used as recycled building aggregates. The traditional crushing device uses crushing rollers, which cannot squeeze and crush large concrete blocks well, and the concrete blocks may not be able to enter The gap to the crushing roller reduces the crushing efficiency

Embodiment 1

[0020] see Figure 1-3 , in an embodiment of the present invention, a construction waste crushing device includes a crushing box 1; multiple groups of crushing rollers 2 arranged longitudinally and equidistantly are arranged in the crushing box 1, and the crushing rollers 2 are connected with a driving device, and the crushing rollers are 2 pairs Concrete blocks are squeezed and crushed.

[0021] The top of the crushing roller 2 is provided with evenly distributed short drill rods 4 and long drill rods 3, and the short drill rods 4 and long drill rods 3 are distributed at intervals; , the sliding frame 5 is nested in the crushing box 1 and is slidingly connected with the inner wall of the crushing box 1; the upper ends of the short drill rod 4 and the long drill rod 3 are respectively fixedly connected with transmission teeth 6, and the upper ends of the long drill rod 3 located in the center are fixedly connected There is a connecting shaft 7, which is rotationally connected...

Embodiment 2

[0025] The difference between this embodiment and Embodiment 1 is that: a grinding cylinder 13 is provided below the crushing roller 2, and a feeding port 14 is provided at the upper end of the grinding cylinder 13; a grinding cone 15 is nested in the grinding cylinder 13, and the grinding cone 15 It is conical, and the grinding cone 15 is connected with a grinding motor 17 through a drive shaft 16, and the grinding motor 17 is fixedly connected with the crushing box 1; the bottom of the grinding cylinder 13 is provided with a discharge port 18 for unloading, and the concrete is crushed by the grinding cone 15. The particles are further ground to further granulate the concrete block, which is convenient for subsequent recycling.

Abstract

The invention discloses a construction waste crushing device. The device comprises a crushing box, wherein a plurality of groups of crushing rollers which are longitudinally arranged at equal intervals are arranged in the crushing box, short drill rods and long drill rods which are uniformly distributed are arranged above the crushing rollers, and the short drill rods and the long drill rods are distributed at intervals. According to the device, the short drill rods, the long drill rods, transmission teeth and a sliding frame are arranged, the short drill rods and the long drill rods can moveup and down while rotating, concrete blocks are drilled and crushed, the problem that the concrete blocks cannot enter into the spaces between the crushing rollers is avoided while accelerating concrete crushing, so that the crushing efficiency is improved; and a grinding cone and a grinding cylinder are arranged, so that the concrete blocks are further granulated, and the subsequent recycling isfacilitated.

Description

technical field [0001] The invention relates to the field of construction waste treatment equipment, in particular to a construction waste crushing device. Background technique [0002] Construction waste has a wide range of erosive effects on our living environment. If construction waste is ignored for a long time, it will have a bad impact on urban environmental sanitation, living conditions, and land quality assessment. First of all, after a large amount of land is piled with construction waste, it will reduce the quality of the soil and reduce the production capacity of the soil; the construction waste is piled in the air, which affects the air quality, and some dust particles will be suspended in the air, which is harmful to human health; The medium and long-term accumulation is that harmful substances of construction waste infiltrate into the groundwater and pollute the water environment; if construction waste is piled up in the city, it is not good for the urban envir...
