Description
Technical Field
The utility model belongs to the technical field of the construction machinery technique and specifically relates to an automatic screening sand machine for job site.
Background
The concrete is an indispensable part in the construction of modern houses, roads and bridges, and is formed by mixing cement, sand, coarse stones and fine stones according to a certain proportion, and the quality of the concrete is directly influenced by the proportion; the sand, which is an important raw material, inevitably contains sand or stones with overlarge particles, which affect the proportion of each composition component of the concrete, so that the sand needs to be screened before production.
The thickness of the sand is an average thickness of sand grains of different grain sizes mixed together. Generally, the sand is divided into coarse sand, medium sand and fine sand. The grain composition of the sand refers to the matching proportion of the sand particles. The graded sand not only can save cement, but also improves the compactness and strength of concrete and mortar.
The method of traditional screening sand is that after people stipulated the sand net, the manual work utilizes the spade to put in the sand on the screen cloth a bit, and fine sand can run through the screen cloth and fall into collection device, and the stone and the great impurity in the sand can be blockked by the screen cloth and stop on the screen cloth on the surface, and the screening sand that utilizes artifical a bit not only wastes time and energy but also the screening sand effect is not good like this, and this problem that leads to traditional screening sand mode practicality to be poor appears.
CN 107737710A discloses an automatic screening sand device, including rectangular frame, the embedded screen cloth that is equipped with of rectangular frame, rectangular frame left surface is equipped with the mounting box No. one, the right side surface is equipped with the rotating electrical machines of rotatory end left in the mounting box No. one, the rotating electrical machines rotatory end is equipped with the decurrent electric putter of catch end No. one, processing has a through-hole on the left of the mounting box front surface, the mounting box below is equipped with No. two mounting boxes, the left side surface is equipped with the No. two rotating electrical machines of rotatory end rightwards in No. two mounting boxes, No. two mounting box right side surface center department processing and No. two through-holes, rectangular frame right side surface is equipped with No. three mounting boxes. The sand screening machine has the advantages that sand screening needs to be performed manually, labor is saved, screened sand is directly collected without being sorted again, and can be manually screened when the using amount is small, so that the sand screening machine can be manually and automatically used, and is not limited to automatic sand screening. But the specification of the screened sand is single, the particle grading of the sand can not be met, and certain use limitation is realized.
Disclosure of Invention
To the not enough of above-mentioned prior art, provide an automatic sand screening machine for job site, its autofilter that has realized the sand has reduced workman's intensity of labour, effectively improves the screening efficiency of sieve, and can realize the sand of screening different specifications simultaneously, satisfies different construction demands, has stronger practicality.
In order to solve the technical problems, the invention adopts the technical scheme that the automatic sand screening machine for the construction site comprises a bottom frame and two bearing frames which are connected with the bottom frame through steel wire ropes and are composed of two longitudinal plates and two transverse plates, a sand screening net is arranged at the bottom of each transverse plate, a driving mechanism for driving the two bearing frames to operate is arranged between the two bearing frames, each driving mechanism comprises an operation frame and driving pipes correspondingly arranged at two sides of the operation frame, a driving cam for driving the operation frame to operate is arranged in each operation frame, a bearing platform is arranged at one side of each operation frame, and a driving motor connected with the driving cam is arranged on each bearing platform.
Foretell an automatic sand screening machine for job site is equipped with between driving tube and diaphragm and is used for the detachable connecting piece of connecting the two, detachable connecting piece includes a connecting plate of locating on the driving tube to and locate the stud on the connecting plate.
In the automatic sand screening machine for the construction site, the mesh aperture of the sand screening net on the left side of the operation frame is larger than that of the sand screening net on the right side.
The utility model discloses an automatic sand screening machine for job site's beneficial effect is, and it has realized the autofilter of sand, has reduced workman's intensity of labour, effectively improves the screening efficiency of sieve, and can realize the sand of screening different specifications simultaneously, satisfies different construction demands, has stronger practicality.
Drawings
Fig. 1 is a schematic structural view of the present invention;
fig. 2 is a schematic structural view of the connection plate.
Detailed Description
The invention is described in detail below with reference to the figures and the embodiments.
As shown in fig. 1 and 2, an automatic sand sieving machine for construction site comprises an underframe 1, two bearing frames which are connected with the underframe through a steel wire rope 2 and are composed of two longitudinal plates 3 and two transverse plates 4, a sand sieving net 5 is arranged at the bottom of the transverse plates, a driving mechanism for driving the two bearing frames to operate is arranged between the two bearing frames, the driving mechanism comprises an operation frame 6 and driving pipes 7 correspondingly arranged at two sides of the operation frame, a driving cam 8 for driving the operation frame to operate is arranged in the operation frame, a bearing platform 9 is arranged at one side of the operation frame, and a driving motor 10 connected with the driving cam is arranged on the bearing platform. It has realized the autofilter of sand, has reduced workman's intensity of labour, effectively improves the screening efficiency of sieve.
Between the driving tube and diaphragm, be equipped with the connecting piece of dismantling that is used for being connected the two, can dismantle the connecting piece and include one and locate connecting plate 11 on the driving tube to and locate the stud on the connecting plate, be equipped with on diaphragm and the connecting plate with the screw 12 of stud adaptation, stud can set up two, reach and connect stable effect. When the impurity on the screening sand net is too much, the detachable connecting piece is detached, and the bearing frame is lifted to dump the impurity.
The mesh aperture of the sand screening net on the left side of the operation frame is larger than that of the sand screening net on the right side. Can realize both sides and screen the sand of different specifications simultaneously, satisfy different construction demands, have stronger practicality.
Of course, the above description is not intended to limit the present invention, and the present invention is not limited to the above examples, and the changes, modifications, additions or substitutions made by those skilled in the art within the scope of the present invention should also belong to the protection scope of the present invention.
