Description
Technical Field
The utility model belongs to the field of machinery, especially, relate to a concrete raw materials screening plant.
Background
Need use sand and stone in the raw materials of concrete, and the diameter grain that the concrete of different specifications needs is different with the sand of stone, consequently often need use the screen cloth to filter, but current sieving mechanism uses the vibrator usually, this raw materials that leads to adding at every turn can not be too much, otherwise the raw materials on upper portion are difficult to down filter, consequently someone adopts the mode that the motor drove the crank to increase and shakes the range, but make the screen cloth remove about through the crank and still can move from top to bottom, not only can cause great load to screen cloth etc. lead to the screen cloth to produce the leak, its life has been reduced. And the use of the cylinder or the oil cylinder requires a corresponding large-scale power source, so that the installation and the movement in real time are inconvenient. In addition, current filter equipment needs the manual work to unload, extravagant manpower.
SUMMERY OF THE UTILITY MODEL
In order to solve the problem, the utility model provides a concrete raw materials sieving mechanism. The utility model discloses simple structure, convenient to use's electric energy drive can be full-automatic select qualified material, has saved the manual work.
In order to achieve the above technical effects, the technical scheme of the utility model is that:
A concrete raw material screening device comprises two screening structures which are oppositely arranged, wherein one screening structure is positioned right above the other screening structure; the screening structures are the same and comprise screen meshes, the screen meshes are arranged on an enclosing frame, rollers are arranged at the bottom of the enclosing frame, a support frame is arranged below the enclosing frame, and a slideway matched with the rollers is formed on the support frame; the surrounding frame is connected with a sleeve, and the sleeve is connected with a sliding rod in a sliding manner; the sleeve is connected with a first connecting rod in a shaft coupling mode, the first connecting rod is connected with a second connecting rod in a shaft coupling mode, and the second connecting rod is fixedly connected with a first motor;
The surrounding frame comprises a lower surrounding frame and an upper surrounding frame; the lower enclosing frame and the upper enclosing frame are hinged with each other, and the screen is connected with the upper enclosing frame; the lower enclosing frame is connected with a second motor in a shaft mode, the second motor is fixedly connected with an internal thread rotating cylinder, the internal thread rotating cylinder is connected with a screw rod in a threaded mode, and the screw rod is hinged to the upper enclosing frame.
In a further improvement, the outer end of the upper enclosing frame is convexly provided with an inclined part.
In a further improvement, the sliding rod is fixed on the bracket.
The utility model discloses simple structure, convenient to use's electric energy drive can be full-automatic select qualified material, has saved the manual work.

FIG. 2 is a schematic top view of the support frame;
Fig. 3 is a schematic view of the overall structure of the present invention.
Detailed Description
The technical solution of the present invention will be described in detail with reference to the following embodiments and accompanying drawings.
Example 1
1-3, a concrete feedstock screening apparatus comprising two oppositely disposed screening structures, one of which is directly above the other; the screening structures are the same and comprise screen meshes 1, the screen meshes 1 are arranged on an enclosure frame 2, rollers 3 are arranged at the bottom of the enclosure frame 2, a support frame 4 is arranged below the enclosure frame 2, and a slide way 5 matched with the rollers 3 is formed on the support frame 4; the surrounding frame 2 is connected with a sleeve 6, and the sleeve 6 is connected with a sliding rod 7 in a sliding manner; the sleeve 6 is connected with a first connecting rod 8 in a shaft mode, the first connecting rod is connected with a second connecting rod 9 in a shaft mode, and the second connecting rod 9 is fixedly connected with a first motor 10;
the enclosure frame 2 comprises a lower enclosure frame 21 and an upper enclosure frame 22; the lower surrounding frame 21 and the upper surrounding frame 22 are hinged with each other, and the screen mesh 1 is connected with the upper surrounding frame 22; the lower enclosing frame 21 is coupled with a second motor 23, the second motor 23 is fixedly connected with an internal thread rotating cylinder 24, the internal thread rotating cylinder 24 is connected with a screw rod 25 in a threaded manner, and the screw rod 25 is hinged with the upper enclosing frame 22.
the outer end of the upper frame 22 is formed with an inclined portion 26.
The slide bar 7 is fixed on the bracket 11.
The utility model discloses a use as follows: for example, if sand of a certain specification needs to be screened, the sand is firstly placed on the screen mesh 1 of the upper screening structure, then the sand rotates correspondingly to the motor, the rotating force of the motor is converted into swinging force which moves left and right through the second rotating shaft and the first rotating shaft, so that the aim of rapidly screening the sand is fulfilled by using the action of screening by a left-right swinging simulator, the screen mesh 1 can screen the sand in large batch, the sand larger than qualified particles is intercepted, then the screened sand falls into the screen mesh 1 of the lower layer to be continuously screened, the sand smaller than the qualified particles is leaked, namely the qualified sand is obtained on the screen mesh of the lower layer. The second motor then rotates to raise the upper enclosure frame 22 by means of the screw, so that the qualified sand is poured into the corresponding hopper or container. Sand with a particle size larger than the specified particle size on the upper screen is also poured into the corresponding hopper or discarded in the same manner.
The above-mentioned is only a concrete direction embodiment of the utility model, nevertheless the utility model discloses a design concept is not limited to this, and all utilize this design right the utility model discloses carry out immaterial change, all should belong to the action of infringing the scope of protection of the utility model.
