Specific embodiment

To keep the purpose of this utility model, technical solution and advantage clearer, below by the technology to the utility model Scheme is described in detail.Obviously, the described embodiments are only a part of the embodiments of the utility model, rather than all Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are not before making creative work Obtained all other embodiment is put, the range that the utility model is protected is belonged to.

Shown in referring to figures 1-4, the utility model provides construction of the highway stone screening plant, including internal is cavity Screen box 1, and upper surface offers charging aperture 101；1 top of screen box is provided with the loading hopper 4 being connected to charging aperture 101； 1 length direction of screen box, one side lower part is provided with the tapping valve 8 of flanged joint, and 1 other side of screen box is provided with water circulation Component 7,7 top of water circulation component are connect by connecting tube 6 with filter assemblies 5, and filter assemblies 5 pass through overflow pipe 3 and screen box 1 Connection；

Screen box 1 offers discharge hole 102 far from 3 one upper lateral part of overflow pipe, and discharge hole 102 is higher than overflow pipe 3, screening Case 1 is internally provided with the barrier 2 that bottom end is lower than discharge hole 102, and 2 upper surface of barrier and two sides are and in screen box 1 Wall connection, and 2 upper end link position of barrier is located at side of the charging aperture 101 far from filter assemblies 5；

Screen box 1 is internally provided with upper end and is pierced by the conveyer belt 10 driven by motor 9, and conveyer belt 10 by discharge hole 102 Lower end is located at immediately below charging aperture 101, and is located at 3 or less overflow pipe；Do not connect between 10 upper surface of conveyer belt and barrier 2 Touching.

As this programme preferred embodiment, 10 inside upper part of conveyer belt is uniformly arranged along its length there are five V-type Support frame 11, and 11 length direction of support frame is vertical with 10 length direction of conveyer belt, and 11 both ends of support frame and 1 inner wall of screen box It is fixedly connected, 10 material of conveyer belt is rubber, and is reticular structure；

So set, passing through the support of support frame 11, to make conveyer belt 10 transmit steadily, and conveyer belt 10 has deformation Ability, then conveyer belt 10 keeps 10 top section of conveyer belt V-shaped under the supporting role of support frame 11, can be in conveying Rising prevents material sideslip from scattering, to improve transmission effect, and silt is allow to fall into 1 bottom of screen box by netted gap Portion；

Filter assemblies 5 include Rose Box 501 and filter cage 504, and screen box 1 is connect with Rose Box 501 by overflow pipe 3, Filter cage 504 is installed inside Rose Box 501, filter cage 504 is the cage construction that top and length direction side are open, and The side of filter cage 504 is open close to overflow pipe 3；504 outer wall of filter cage is in contact with 501 inner wall of Rose Box, on filter cage 504 Portion is provided with case lid 503, and 503 upper surface center of case lid is fixedly installed with handle 502, and the floating inside screen box 1 is miscellaneous Object enters Rose Box 501 by overflow pipe 3, and water flow can carry out sundries after entering Rose Box 501 by filter cage 504 Filter, and water circulation component 7 is inputted from affiliated connecting tube 6；When filter assemblies 5 are using after certain time, operator passes through handle Filter cage 504 by taking out inside Rose Box 501, and is cleared up filter cage 504 by hand 502；After cleaning is completed, it can incite somebody to action Filter cage 504 is reinstalled in inside Rose Box 501；

Water circulation component 7 include water tank 701 and water pump 703, screen box 1 far from 8 one side lower part of tapping valve by flange with Water pump 703 connects, and 703 top of water pump is connect by delivery pipe 702 with water tank 701, when needing to carry out stone screening, beats first Boiled water pump 703, water pump 703 enters the water pump 703 inside water tank 701 inside screen box 1, makes to screen by complement filter component 5 Water circulation is formed inside case 1；After stone is completed to screen, open tapping valve 8, water pump 703 to sending water inside screen box 1, and 1 bottom of screen box is rinsed, thus by inside screen box 1 sewage and silt be discharged by tapping valve 8；

Using the above structure, when needing to screen stone, it will add inside screen box 1 add water to height of water level first Between overflow pipe 3 and discharge hole 102, then stone to be screened is added in loading hopper 4, stone is entered by loading hopper 4 Inside screen box 1；10 surface of conveyer belt is fallen in after the water that stone is fallen into inside screen box 1, and is sent by conveyer belt 10 to discharge hole 102 outputs；Lighter impurity swims in circulation water surface, and concentrates on barrier 2 and screening under the effect of blocking of barrier 2 In the cavity that 1 inner wall of case is formed, then exported along overflow pipe 3 to recirculation assembly with recirculated water, heavier impurity falls in conveyer belt On 10, and 1 bottom of screen box is fallen into the flushing of recirculated water；After the completion of stone screening, tapping valve 8 is opened, water is then opened and follows Ring assemblies 7, water circulation component 7, can be to 1 bottom deposits of screen box to being directly discharged through tapping valve 8 after sending water inside screen box 1 Silt is rinsed.

By setting conveyer belt and water circulation component, continuous screening and removing impurities can be carried out to stone, netted conveyer belt can The silt in stone is sieved into screen box bottom, screening efficiency is high, and good impurity removing effect；

By the filter assemblies of installation and the cooperation of water circulation component, screened water can be filtered, and make water flow Water circulation is formed inside screen box, recycling, to realize water-saving result, the feature of environmental protection is good.

Above description is only a specific implementation of the present invention, but the protection scope of the utility model is not limited to In this, anyone skilled in the art within the technical scope disclosed by the utility model, can readily occur in variation Or replacement, it should be covered within the scope of the utility model.Therefore, the protection scope of the utility model should be with the power Subject to the protection scope that benefit requires.
