A raw material conveying mechanism, a sand screening mechanism, a feeding mechanism and an operating box are respectively mounted on the frame car, the sand screening mechanism is mounted right above the frame car, the raw material conveying mechanism is mounted on the left upper side of the sand screening mechanism, one end of the feeding mechanism is arranged right below the sand screening mechanism, the other end of the feeding mechanism is arranged on the right upper side of the sand screening mechanism, an operating box is arranged on one side of the feeding mechanism on the frame car, and a speed regulator for controlling movement of the frame car is arranged on the operating box. The full-automatic sand screening feeder has functions of automatically taking, screening and feeding sand, and has the advantages of structural stability, convenience in operation, high degree of automation and labor-saving and time-saving performance.

Description

technical field [0001] The invention relates to a sand screening machine, in particular to a fully automatic sand screening and feeding machine. Background technique [0002] In construction sites, etc., it is necessary to sieve out the coarse sand and stones in the sand. At present, sand screening on the market is generally carried out manually. The raw material sand transported is manually poured into the screen, and the screen is manually shaken to screen the sand. The fine sand screened by the sand screen machine is then manually transported and poured In the mixer, this kind of manual sand sifting is time-consuming and laborious, and it is increasingly unable to meet the needs of the market. [0003] With the advancement of science and technology and the demand of the market, in recent years, many different types of sand screening machines have appeared on the market. Most of them only realize automatic sand screening in the sand screening part. The transportation of ...

Problems solved by technology

At present, sand screening on the market is generally carried out manually. The raw material sand transported is manually poured into the screen, and the screen is manually shaken to screen the sand. The fine sand screened by the sand screen machine is then manually transported and poured In the mixer, this kind of manual sand sieving is time-consuming and laborious, and it is increasingly unable to meet the needs of the market.

[0003] With the progress of science and technology and the demand of the market, in recent years, many different types of sand screening machines have appeared on the market, most of which only realize the automatic screening of the sand screening part Sand, other such as transporting the raw material sand to the sieve, and transporting the fine sand after the sieve to the mixer, etc., still need manpower to complete, such as the Chinese patent, the publication number is CN 202143877U, and the publication date is 2012.02.15, The invention patent application named "Sand Screening Machine" has the main technical features: it includes a frame with a hopper, and the frame is equipped with a conveyor belt connected to the first motor and a roller connected to the second motor. The above-mentioned hopper is provided with a stirring shaft with stirring hands, and the stirring shaft is connected with the second motor. The emergence of this sand screening machine has solved the time-consuming and laborious situation of manual sand screening to a certain extent, but still requires a forklift or manual The raw sand is transported to the screen, and the fine sand screened by the screen also needs to be manually transported to the mixer, which still consumes a lot of manpower, and the efficiency is low, and it still cannot meet the current market demand.
