Problems solved by technology

[0003] At present, there are often a lot of construction waste on the construction site, and it takes a lot of time and manpower to place a large number of them. Because most of the waste is large in size and different in size, it increases the difficulty of construction. In view of this phenomenon, now There are some

Example Embodiment

[0019] Example 1

[0020] see Figure 1~3 , in an embodiment of the present invention, a construction waste crushing and recycling device includes a base 1, a fixed outer frame 2, a crushing shell 3 and a crushing shell 4, the base 1 is fixedly mounted with a fixed outer frame 2, and the fixed outer frame 2 The crushing shell 4 is installed, and the crushing shell 3 is fixedly installed on the fixed outer frame 2. The crushing shell 3 is provided with a crushing chamber 6, and a pair of crushing rollers 7 with opposite rotation directions are installed in the crushing chamber 6. The surface of the crushing roller 7 is Teeth 8 are fixed, and a lower hopper 5 is installed on the top of the crushing shell 3. When the construction waste put into the lower hopper 5 enters between the crushing rollers 7, it can be crushed by the relatively rotating crushing rollers 7. The crushing chamber The bottom of the crushing chamber 6 is connected to the crushing shell 4 through the discharg...

[0023] Example 2

[0024] see Figure 1~3 , this embodiment is mainly to further illustrate the driving structure of the crushing roller 7 and the crushing blade 11. Specifically, the crushing shell 3 is equipped with a gear box 19, and the gear box 19 is equipped with a crushing motor 17, and the crushing motor 17 The output end stretches into the gear box 19 and is fixedly connected with the driving gear 14. The gear box 19 is also provided with a driven gear one 15 and a driven gear two 16 which mesh with each other. The driven gear one 15 and the driven gear two 16 are installed on the axle ends of two crushing rollers 7 respectively, and driving gear 14 meshes with driven gear one 15 or driven gear two 16 for realizing the relative rotation of two crushing rollers 7 . A crushing motor 18 is fixed outside the crushing shell 4, and the output end of the crushing motor 18 is connected with the drum for driving the drum to rotate at a high speed. Both the crushing motor 17 ...

Abstract

The invention discloses a building waste crushing and recycling device. The building waste crushing and recycling device comprises a base, a fixed outer framework, a breaking outer casing and a crushing outer casing, wherein the fixed outer framework is fixedly arranged on the base; the crushing outer casing is arranged in the fixed outer framework; the breaking outer casing is fixedly arranged onthe fixed outer framework; the interior of the breaking outer casing is provided with a breaking cavity; a pair of breaking rolls with opposite directions is arranged in the breaking cavity; teeth are fixedly arranged at the surface of each breaking roll; a material discharge hopper is arranged at the top part of the breaking outer casing; the bottom part of the crushing cavity is connected withthe crushing outer casing through a material falling port; the crushing outer casing is provided with a circular inner cavity; the crushing outer casing is provided with a material outlet at the tangential line of the bottom part. The building waste crushing and recycling device has the beneficial effects that under the synergistic function of the devices in the breaking outer casing and the crushing outer casing, the building wastes can be firstly broken and then crushed; the whole process is simple, the efficiency is high, the integration degree is high, the emission amount of dust is low inthe working process, and the building waste crushing and recycling device can be widely applied into the field of buildings.

Description

technical field [0001] The invention relates to the technical field of construction, in particular to a construction waste crushing and recycling device. Background technique [0002] With the development of social economy, my country continues to deepen urban construction, because my country's modern urban construction is mainly based on concrete buildings, and concrete buildings have a certain service life limit due to aging problems. The service life of concrete buildings in my country is mostly designed to be about 70 years. These old buildings urgently need to be demolished and rebuilt. At the same time, because many earthquake disasters have occurred in my country in recent years, some old concrete buildings whose service life has not yet expired are due to earthquake resistance. The unsuitability of the structural design also required demolition and reconstruction. [0003] At present, there are often a lot of construction waste on the construction site, and it takes ...
