Description
Technical Field
[0001] The utility model relates to the technical field of sand and gravel screening, and more specifically to a sand and gravel screening device for construction engineering. Background Art
[0002] Construction engineering refers to the activities of constructing and installing buildings and structures using building materials and engineering technology within a certain location and space, in accordance with design requirements and construction plans.
[0003] Sand and gravel screening devices are commonly used in construction projects to screen and separate granular materials such as sand and gravel. This type of device usually includes equipment such as vibrating screens and rotary screens. Through different screen hole sizes and screen materials, impurities of different particle sizes in the raw materials can be separated to ensure the quality of building materials and construction effects.
[0004] The existing sand and gravel screening device still has the following problems: when screening, the existing sand and gravel screening device often uses a screening plate in conjunction with a vibration motor to vibrate and screen the sand and gravel. In this process, the dust inside the sand and gravel is very easy to be raised. Such dust will undoubtedly bring great pollution to the working environment of the personnel, seriously affecting the working environment of the personnel, and even affecting their health;
[0005] Secondly, the existing sand and gravel screening devices often need to screen sand and gravel of different particle sizes, but the screen plate often needs to be replaced when screening according to the particle size. The existing replacement methods mostly use professional tools to remove the screws used to fix the screen plate. This results in a lot of time and manpower required every time sand and gravel of various sizes need to be screened, which is extremely inconvenient to use.
[0006] In view of this, we propose a sand and gravel screening device for construction engineering. Utility Model Content

[0017] 3. Beneficial effects
[0018] Compared with the prior art, the advantages of the utility model are: when it is necessary to screen the sand and gravel, the sand and gravel can be put into the feed hopper first, and then a plurality of vibration motors can be used to drive the sieve plate frame carrying the sieve plate to vibrate, and the vibration and the sieve plate can be used to screen the sand and gravel. In this process, a water pump can be used in combination with a water spray head to spray water on the sand and gravel to reduce dust, so as to avoid the dust from being raised and affecting the working environment of the staff. Secondly, the water source after the dust is sprayed can fall on the metal filter net through a plurality of sieve plates for filtration, so that it returns to the inside of the fixed box, and then it can be better recycled, effectively reducing the waste of water resources. Secondly, if there are more impurities accumulated on the metal filter net, a plurality of screw motors can be used to drive the rubber scraper to scrape the impurities on the metal filter net and drop them into the discharge trough for collection, so as to avoid the accumulation of impurities affecting the filtering effect of the metal filter net.

After that, the limit on the screen plate can be released, and then the screen plate of the top screening assembly can be pulled out using the pull groove and replaced with a screen plate of suitable caliber. The installation can be done in reverse, which can better reduce the tediousness of screen plate replacement, effectively improve the screening efficiency and facilitate screening of sand and gravel particles of various sizes.
