Abstract
Description
Technical Field

[0002] Sand and gravel aggregates are the general names of materials such as sand, pebbles, crushed stones, block stones, and dressed stones in water conservancy projects. According to different uses, the particle sizes of the sand and gravel aggregates used are different. In actual use, sieves with different apertures are required to screen the sand and gravel aggregates. At present, the sand and gravel aggregates are usually screened by vibrating screens, which takes less time and has higher screening efficiency.
[0003] However, in the actual use of the existing method for screening sand and gravel aggregates, due to the vibration of the sieve, some sand and gravel aggregates may get stuck in the sieve holes, and as the vibration becomes tighter and tighter, it is necessary to stop the machine and manually remove the sand and gravel aggregates stuck in the sieve holes, which seriously increases the working hours and has low efficiency. In view of this, and when the sand and gravel aggregates are screened by a vibrating screen, dust will fly during the screening process, which endangers the physical health of workers and is not environmentally friendly. In view of this, a sand and gravel aggregate vibrating screen is now proposed. Content of the Utility Model
