Description

Technical Field

[0001] The utility model relates to the technical field of equipment for construction engineering, in particular to a crushing device for construction engineering. Background Art

[0002] Building is a general term for buildings and structures. People use the material and technical means they have mastered to meet the needs of social life. During the construction of construction projects, a large amount of building material waste with high hardness will be generated. In order to save space and recycle, crushing equipment will be used to crush it.

[0003] Some equipment on the market generally lifts the rotating arm under the action of the support seat, and then limits it through the auxiliary limit assembly, and then starts the pressing assembly. Under the action of the pressing assembly, the crushed garbage can be pressed down, so that the crushing roller inside the crusher body can crush the garbage more efficiently.

[0004] However, in actual use of the above equipment, when materials are continuously input, the materials that have not been completely crushed in the first part will cause a certain amount of accumulation inside the crushing device. The natural descent of the materials under their own gravity causes the crushing progress inside the crushing device to be low, affecting the overall crushing efficiency of the device. In view of this, we propose a crushing device for construction engineering. Utility Model Content

[0010] Preferably, the size of the collecting member is matched with the size of the interior of the shell, and the collecting member is arranged above the crushing roller, so that the material inside the collecting member can better contact with the crushing roller.

[0011] Preferably, the size of the fixing block matches the size of the mounting groove, and the size of the sliding groove matches the size of the sliding block, which allows the sliding block to move well inside the sliding groove.

[0012] Preferably, the position of the limiter corresponds to the position of the rotating shaft of the crushing roller, and one end of the electric telescopic rod passes through the top of the shell and is fixedly connected to the pressing block, which enables the pressing block to press the material well.

[0015] Compared with the prior art, the utility model provides a crushing device for construction engineering, which has the following beneficial effects:

[0016] 1. In order to prevent a large amount of material from entering the equipment and causing blockage, the crushing device for construction engineering puts the material into the feed port, and the material falls through the conveyor belt to the crushing rollers arranged inside the shell for crushing. When the material is piled up, the material will be stuck inside the collecting piece, so that the material will press the collecting piece downward, which makes the material fall with the collecting piece. At the same time, the limiter arranged at the bottom of the collecting piece contacts the outer surface of the rotating shaft of the crushing roller, which stops the collecting piece from descending, and the material at the center of the collecting piece contacts between the two crushing rollers. The inner wall of the collecting piece is funnel-shaped, so that the material inside the collecting piece can better contact with the crushing rollers for crushing, and at the same time, the pressing block presses the material downward, so that the material is crushed faster and will not be blocked.

[0017] 2. In order to make the materials fall better into the center of the crushing roller, the materials will contact the inner wall of the baffle when entering the feed port. The baffle is U-shaped and the inner wall of the baffle is inclined, which allows the materials to fall well on the upper surface of the conveyor belt. When the materials fall from the upper surface of the conveyor belt, they contact the guide, which is trapezoidal, so that the materials can fall better in the center of the crushing roller for crushing.
