Description

Technical Field

[0001] The utility model belongs to the technical field of construction engineering, in particular to a stone crushing device for building earth and stone. Background Art

[0002] Buildings refer to man-made assets, which belong to the category of fixed assets, including houses and structures. Houses refer to engineering buildings for people to live, work, study, produce, operate, entertain, store goods and carry out other social activities. What is different from buildings is structures, which refer to engineering buildings other than houses. In the construction process, construction earthwork is indispensable, and there is a lot of earthwork and gravel that needs to be broken up and recycled for secondary use.

[0003] Most construction earth and stone are broken manually by vibrating the earth and stone with electric hammers. This method of work is very labor-intensive and inefficient. It generates a lot of dust and easily affects the health of operators. At the same time, the broken stone needs to be screened after the operation, which is time-consuming and labor-intensive.

[0004] In order to solve the above problems, the purpose of the utility model is to provide a stone crushing device for construction earthwork.

[0005] To achieve the above-mentioned purpose, the utility model proposes a stone crushing device for construction earth and stone, including a crusher, a motor is fixedly installed on the outside of the crusher, a first crushing plate and a second crushing plate are symmetrically installed inside the crusher, a roller is movably installed inside the crusher, crushing rods are evenly installed on the outside of the roller, a screen plate is fixedly installed between the first crushing plate and the second crushing plate, and the shape of the screen plate is arc-shaped.

[0006] Preferably, a feeding port is fixedly provided at the upper end of the crusher, and a protective plate is annularly installed outside the feeding port.

[0007] Preferably, a transmission shaft is movably mounted at the front end of the motor, a stabilizing frame is fixedly mounted on the outside of the transmission shaft, and a transmission wheel is fixedly mounted on the front end of the transmission shaft.

[0008] Preferably, a bracket is symmetrically mounted on the lower end of the crusher, a collecting trough is movably mounted on the bottom end of the crusher, and a handle is fixedly mounted on the outer side of the collecting trough.

[0009] Preferably, a transmission belt is movably installed outside the transmission wheel, and one end of the transmission belt is movably connected to a linkage wheel.

[0010] Preferably, a plurality of crushing teeth are fixedly mounted on the inner sides of the first crushing plate and the second crushing plate, and a plurality of guide plates are fixedly mounted on the lower end of the screen plate.

[0011] The stone crushing device for construction earthwork proposed by the utility model can bring the following beneficial effects:

[0012] 1. The utility model is provided with a mechanical stone crushing device. When in use, stones are put into the device. An inclined crushing plate is installed inside the device. Crushing teeth are installed on the side of the crushing plate. Meanwhile, a rotating roller is installed inside the device. A plurality of crushing rods are installed outside the rotating roller. The crushing rod drives the stone and the crushing plate to vibrate and squeeze, so that the stone is crushed. Since the crushing plate is inclined, the distance between the lower end and the rotating roller is getting closer and closer, so that the stone is gradually crushed. The mechanical device performs stone crushing operation, consumes less manpower, and improves work efficiency.

[0013] 2. The utility model has a screen plate installed inside the device, and an arc-shaped screen plate is installed at the lower end of the crushing plate. After the stone is gradually crushed, the crushed stone that meets the specifications is screened out under the action of the screen plate, and the crushed stone that does not meet the specifications is reciprocated by the action of the roller, thereby improving the processing effect of the device and reducing manual operation.
