Technical Field

The invention relates to the technical field of building construction, in particular to a crusher for buildings.

Background

In the construction process of a building, the construction waste needs to be recycled after being crushed. The conventional crushing device generally only uses the crushing blade to perform rotary cutting crushing on the waste materials, and the crushing efficiency is low.

Disclosure of Invention

The invention aims to provide a building crusher, which can overcome the defects of the prior art and improve the crushing efficiency of building waste.

In order to solve the technical problems, the technical scheme adopted by the invention is as follows.

The utility model provides a rubbing crusher for building, includes the casing, and casing lateral wall is provided with the dog-house, and chassis bottom is provided with the bin outlet, transversely install the rotation axis in the casing, the one end and the driving motor of rotation axis are connected, and driving motor installs outside the casing, evenly installs a plurality of crushing blade on the rotation axis, and the clamp plate is installed through the hydro-cylinder at the top of casing.

Preferably, a plurality of supports are fixed at the bottom of the machine shell, supporting wheels are axially connected on the supports and meshed with the crushing blades right above the supporting wheels, and at least one suspended crushing blade is arranged between every two adjacent supporting wheels.

Preferably, the outer side of the supporting wheel is provided with a stirring paddle.

Preferably, the supporting wheel is provided with an annular groove which is meshed with the crushing blades, the side wall of the annular groove is provided with notches which are in one-to-one correspondence with the stirring paddles, and the notches are positioned on the outer side of the stirring paddles.

Preferably, the stirring paddle is provided with a plurality of parallel through grooves, a guide plate is fixed in each through groove, and the included angle between each guide plate and the stirring paddle is 45 degrees.

Preferably, two ends of the rotating shaft are connected with the machine shell through bearings, each bearing comprises an inner sleeve and an outer sleeve which are sleeved with each other, an installation frame is installed between the inner sleeve and the outer sleeve, and balls are installed in the installation frame; the inner sleeve and the outer sleeve are respectively provided with a sliding groove, the mounting frame is in sliding clamping connection in the sliding grooves, two ends of a contact part of the mounting frame and the rolling balls are respectively provided with a rubber ring, and the edge of a contact surface of the rubber ring and the rolling balls is provided with an oil storage tank.

Preferably, the edge of the mounting bracket contacting the sliding groove is provided with an arc-shaped buffer part.

Adopt the beneficial effect that above-mentioned technical scheme brought to lie in: according to the invention, the waste is pressed down by the pressing plate while the crushing blade is rotated and crushed, so that the contact pressure between the waste and the crushing blade is effectively improved, and the crushing efficiency is improved. Through at casing bottom installation supporting wheel, can improve the radial shock resistance intensity of rotation axis on the one hand, on the other hand can utilize the rotation of supporting wheel to stir the waste material, makes the waste material of chassis bottom upwards turn to further improve crushing efficiency. Through the optimization to the stirring rake structure, can improve the stirring effect of stirring rake to bulky waste material. In addition, because the both ends of rotation axis are connected with the casing through the bearing, through the optimization to the bearing, further improve the installation stability of rotation axis. The invention provides a sliding fit structure of the mounting frame with the arc-shaped buffering part and the sliding groove for the first time, and meanwhile, the rubber ring with the oil storage groove is arranged, so that the elastic deformation of the arc-shaped buffering part can be fully buffered, and the surface abrasion of the ball under the condition of large impact force can be avoided.
