Garbage crushing device for constructional engineering

Abstract

The invention discloses a garbage crushing device for constructional engineering in the technical field of constructional engineering. The garbage crushing device comprises a base with rollers, wherein a pushing handle is fixed to the left end of the base; supporting rods are fixed to the periphery of the upper end of the base; a box body is fixed to the upper ends of the supporting rods; a crusher is fixed inside the box body; a discharging seat is fixed to the middle of the box body; the upper end of the discharging seat is arranged to be in a funnel shape; a discharging opening is formed inthe middle of the discharging seat; a rotating shaft is rotationally limited inside the discharging seat; a plurality of rotating blades are uniformly arranged at the position, positioned inside thedischarging opening, of the outer side of the rotating shaft; a rectangular plate is fixed to the outer end of the box body; a transmission motor is fixed to the upper end of the rectangular plate; anoutput shaft of the transmission motor is connected with the rotating shaft; and a first transmission mechanism and a second transmission mechanism are arranged on the upper side and the lower side of the output shaft of the transmission motor correspondingly. According to the garbage crushing device, the transmission motor rotates to drive the rotating blades to rotate, so that a discharging hole is prevented from being blocked, the discharging speed is reduced, the operation is convenient and fast, and dust can be prevented from escaping out of the box body in the crushing process.

Description

technical field [0001] The invention relates to the technical field of construction engineering, in particular to a garbage crushing device used in construction engineering. Background technique [0002] China is in a period of rapid economic development, and hundreds of millions of tons of construction waste are inevitably produced every year, such as cement blocks, stones, abandoned welding slag, welding rods, and small metal objects. At present, the amount of construction waste in China has accounted for the total urban waste. One-third of the amount, if not processed and utilized in time, will definitely bring adverse effects to society, environment and resources. [0003] The patent publication No. CN210545602U discloses a construction waste crushing device for construction engineering, which belongs to the field of construction waste crushing. A construction waste crushing device for construction engineering includes a box body, and the surface of the box body is provi...

Problems solved by technology

[0004] Although the above-mentioned scheme has realized the crushing of construction waste, there are still deficiencies: one is that in the above-mentioned scheme, the construction waste that has been crushed for the first time passes through the discharge hole during the process of falling, which will easily cause the discharge hole to be blocked, and the construction waste can be blocked in one time. The speed and amount of falling are large, resulting in insufficient secondary crushing; secondly, because construction waste is prone to generate a large amount of dust during the crushing process, once the dust overflows the box, it is easy to cause injury to the operator; thirdly, in the above scheme The device is not easy to move, and it is not convenient to transfer according to the location of the construction waste
