Description

Concrete mixing plant sandstone two-wire blanking device

Technical field

The utility model is related to a kind of mixing plant sandstone blanking device, more particularly to a kind of concrete mixing plant sandstone two-wire Blanking device.

Background technology

With continuing to develop for urban construction, construction site to ready-mixed concrete the need for also more and more, premixing coagulation Soil refer to by cement, gather materials, the component such as water and the additive mixed as needed, mineral admixture by a certain percentage, stirring Mix that station is sold after metering, mixing and use transport vehicle, the concrete mix of place to use is transported at the appointed time.

The production of ready-mixed concrete generally comprises below scheme：Raw material enters factory, stock ground heap sand, sandstone blanking transport, proportioning Metering and stirring discharging, the sandstone of sandstone factory accumulation are needed on the belt conveyor by hopper blanking to underface, then Concrete mixer is entered by belt conveyor.

But in actual production process, larger stone can be mixed into sandstone, these exceed concrete and stir standard Major diameter stone be not only able to block hopper, cause blanking slow, stir serious once entering in concrete mixer It has impact on concrete mixing amount of substance.

Utility model content

The purpose of this utility model, which is to provide, a kind of can filter the concrete mixing plant sandstone two-wire blanking compared with ratchel Device.

Above-mentioned technical purpose of the present utility model technical scheme is that：

A kind of concrete mixing plant sandstone two-wire blanking device, including discharging platform on the ground is installed, positioned at discharging Be arranged side by side two groups of blanking bins below platform and the discharging opening for corresponding to every group of blanking bin respectively immediately below blanking bin Feed belt, the discharging platform reaches the track of discharging platform and covering between track including both sides for dumper On the screen cloth covered above blanking bin, the orbit plane multiple auxiliary feed openings are offered along the length direction of track.

By using above-mentioned technical proposal, dumper opens upper rail, then during track is pulled back from downwards Blanking bin in carry out batch turning, sandstone enter blanking bin before by filter screen filtration, the sandstone for not meeting normal diameter is filtered Net filtration, larger stone is left on screen cloth, and the auxiliary feed opening opened up in orbit in addition is while can be to larger sand Stone carries out filtering blanking, the filtering by screen cloth with auxiliary feed opening to sandstone so that larger stone will not enter blanking bin It is interior, it is to avoid blanking bin blocking, it is ensured that the blanking velocity of sandstone, while also make to ensure that concrete mixing amount of substance.

Preferably, every group of blanking bin segmentation has at least four hoppers.

By using above-mentioned technical proposal, set two groups of blanking bins to carry out two-wire transport below discharging platform, improve Sandstone transmission efficiency, in addition each blanking bin be divided into four hoppers, sandstone can be from four hoppers blankings simultaneously, can either Accelerate the blanking velocity of sandstone so that sandstone uniformly can be spread out on feed belt, while can also reduce sandstone under The impulsive force of square feed belt.

Preferably, the section of the hopper is trapezoidal.

By using above-mentioned technical proposal, the trapezoidal hopper in section facilitates the blanking of sandstone, more effectively keeps away The blocking of sandstone is exempted from.

Preferably, the auxiliary feed opening is equidistantly arranged at intervals along track length direction.

By using above-mentioned technical proposal, dumper constantly batch turning in reversing process again, sandstone can be dropped on track, Auxiliary hopper on track can carry out blanking filtering to sandstone simultaneously, more effectively reduce sandstone heap in orbit Product, equidistantly spaced auxiliary feed opening adds the frictional force that raceway surface is contacted with dumper wheel in addition so that Haul is in stable enforcement in orbit.

Preferably, the both sides of the screen cloth are respectively fixedly connected with orbit, screen cloth is in middle high, both sides low setting.

By using above-mentioned technical proposal, sandstone is largely poured over the surface of screen cloth, can form heap on the surface of screen cloth Product, will shine net and sets in the low arch in middle high, two ends, enables to be poured on and shines online sandstone and is rolled on screen cloth, increase Mobility of the sandstone on screen cloth, angle improves sandstone blanking velocity effectively to avoid accumulation of the sandstone on screen cloth.

Preferably, being fixedly connected with bracing piece between two tracks and positioned at equidistant be spaced in lower section of the screen cloth.

By using above-mentioned technical proposal, sandstone is poured over solarization on the net by a large amount of, and larger impact can be formed to screen cloth, long Time is used, and screen cloth is easily bent, or even can be fractureed, and the bracing piece fixed at equal intervals in the lower section of screen cloth can Play a part of support to screen cloth, strengthen, more effectively raise the service life for shining net, reduce the maintenance of screen cloth into This.

Preferably, the hopper, which is located on the side wall of discharging opening, is fixedly connected with vibrating motor.

By using above-mentioned technical proposal, easily blocked during sandstone blanking above the discharging opening of hopper, under A vibrating motor is fixedly connected with the side wall of hopper, continual in sandstone blanking discharging opening can be vibrated, So that sandstone is not easy to accumulate in discharge outlet, the blocking of sandstone is more effectively avoided.

Preferably, the side of the feed opening is fixedly connected with the inclined buffer board of feed belt downwards.

By using above-mentioned technical proposal, sandstone from hopper flow down when speed, cause transmission of the sandstone to lower section Belt impulsive force is larger, causes belt serious wear, by the inclined buffer board set in discharge outlet, and sandstone can be risen To the effect of buffering blanking, impulsive force of the sandstone to feed belt surface is reduced, the abrasion of feed belt is reduced.

Preferably, the back side of the buffer board is fixedly connected with two support bars being parallel to each other, support bar is away from buffering One end of plate is each fixedly connected on the both sides of the feed belt.

By using above-mentioned technical proposal, support bar is set at the back side of buffer board, bracing reinforcement can be played to buffering Effect so that buffer board can stablize row buffering is entered to sandstone.

In summary, the utility model has the advantages that：

1st, by setting two-wire blanking bin to improve the transmission efficiency of sandstone；

2nd, sandstone blanking velocity can be accelerated by the way that blanking bin is divided into multiple hoppers；

3rd, enable to sandstone that there is mobility by the low screen cloth in high, two ends in the middle of setting, accelerate blanking velocity, separately Outer screen cloth can filter the stone for not meeting normal diameter size, it is to avoid the blocking of hopper；

4th, the accumulation of sandstone in orbit can be reduced by the auxiliary feed opening set in orbit.
