Description

Simple screening hopper

Technical Field

The utility model belongs to the engineering machine tool field, concretely relates to simply sieve and fight.

Background

The grain size of materials is required in engineering construction, and only stone materials within a certain grain size range are usually selected, but the supplied mixture has different grain sizes and large span, so that the mixture needs to be screened. The common method is that a bucket of an excavator is used for conveying the mixture to a screen of a screening machine for screening, unqualified stone materials are piled on a construction site for being crushed again after screening is finished, and a large amount of useless stone materials are inconvenient to pile on the construction site with a small temporary material preparation site. In addition, need earlier to transport the mixture to the screening machine with the scraper bowl during screening operation, still need to transport the building stones that meet the requirements to the operation place after the screening is accomplished, operation process is complicated loaded down with trivial details, and operating time is long, and work efficiency is low.

Disclosure of Invention

The utility model discloses in overcoming the problem that current building stones screening operation is inconvenient, work efficiency is low, providing a simple and easy screening of convenient and fast screening building stones is fought.

The simple screening hopper is characterized in that the screening hopper can directly shovel mixed materials stacked on the ground into the screening hopper, enclosing blocks are arranged on the rear side, the left side and the right side of the screening hopper, materials are shoveled on the front side, and a grid-shaped screen is arranged on the bottom surface.

The utility model discloses a screening fill directly digs the mixture and falls into certified products and unqualified material with the mixture screening, and the certified products leaks down from the net of screen cloth, and the unqualified material then stays in the screening fill, does not need shovel building stones many times, also need not use the screening machine, only relies on simple and easy screening fill can accomplish the screening. Qualified materials are transported to a temporary material preparation field of a construction site to be stacked for standby application, the stone materials in the material preparation field are qualified, and the purpose of material clearing after work can be achieved.

The screening bucket is formed by transforming an excavator bucket, and the closed bottom surface of the bucket is changed into a grid-shaped screen.

The closed back of the screening hopper is changed into a grid-shaped screen.

The bottom surface and the back surface of the bucket are cut to form hollow parts, and a screen is installed at the hollow parts.

The bucket is transformed to obtain the screening bucket, the screening bucket is provided with a power device, the transformation is convenient, and the cost is low.

The mesh width of the screen is not more than 30 cm and not less than 25 cm.

The stones with the grain size of less than 30 cm can be directly separated for use, the stones with the grain size of more than 30 cm are crushed for a plurality of times until meeting the requirements, and the width of the grid can not be too small in order to ensure that most stones meeting the requirements can be screened out.

The mesh width of the screen is not more than 1 cm.

The denser grid can be used for soil and stone separation, and the stones in the soil pile are separated to obtain clean soil which can be directly used for backfill soil on the back of the retaining wall or soil for construction, so that the separation speed is high, and the operation is convenient.

The utility model discloses the less building site in specially adapted place of prepareeing material temporarily sieves in advance, ensures that the building stones of transporting the building site all are qualified building stones, avoids too much to occupy the place.

Detailed Description

The embodiments illustrated herein will enable those skilled in the art to more fully understand the present invention, without limiting it in any way, when the present invention is described in detail below with reference to the accompanying drawings.

As shown in fig. 1 to 3, the utility model provides a simple screening bucket 1, it is that the scraper bowl of excavator 2 is reformed transform and is formed, adopts the cutting technology to demolish the bottom surface of scraper bowl, welds net shape screen cloth 11 in fretwork position, selects the net 12 size of different screen cloths 11 according to the size requirement of screening building stones. Further, the back and the bottom surface of scraper bowl are all demolishd, and increase screen cloth 11 area can sieve qualified building stones from screen cloth 11 more, improves work efficiency, and avoids qualified building stones to press from both sides the unable accuracy in dead angle between the too big stone of particle diameter and the scraper bowl back and sieve out, improves the degree of accuracy of screening building stones. Grid 12 has two kinds of sizes, and big net screen cloth 11 is the stone that sieves particle size 30 centimetres below, can both be sieved out for most stone material that meets the requirements, and the width of grid 12 is not more than 30 centimetres and is not less than 25 centimetres. The dense screen mesh 11 with small meshes can be used for soil and stone separation, and the dense screen mesh with the mesh width not more than 1cm can separate stones in the soil and stone mixture from the muck.

Example 1

The large grid screen with the grid 12 width not more than 30 cm and not less than 25 cm is adopted to screen the stone particle size, and the screening hopper 1 screens the stone with qualified particle size and the stone with unqualified particle size. The unqualified grain diameter stone can be screened, dug and stacked for cracking treatment, and then the unqualified grain diameter stone and the qualified grain diameter stone are loaded together and transported to a construction site for use, so that temporary storage and secondary cracking caused by the fact that the grain diameter of the stone does not meet the design requirement after the stone is transported to the construction site are avoided. The method is suitable for masonry engineering with narrow temporary material preparation site on a construction site, difficult long-term storage of building materials, more professional types, more interference factors, short construction period and strict engineering progress requirement. The simple screening hopper 1 is utilized to screen stones (the diameter is not more than 30 cm) with the grain diameters meeting the design requirements in a quarry in advance, the condition that the finished materials are clear every day on a construction site is ensured, the input amount of stones every day is fully utilized, and favorable conditions are created for site civilized construction and scientific management.

Example 2

Adopt 12 width on net to be not more than 1 cm's intensive screen cloth can be used to the soil and stone separation and handle, carry out the screening pile with stone and dregs, and the clean soil of separating can directly be used to retaining wall back backfill soil or for the building soil. The stone can be reused as building materials, such as site hardening, temporary pavement building materials in the site and the like.

The rest parts which are not described in the prior art.

Above embodiment only is for explaining the utility model discloses a technical thought can not be injectd with this the utility model discloses a protection scope, all according to the utility model provides a technical thought, any improvement of doing on technical scheme basis and equal replacement all fall into within the protection scope of the utility model.
