Background technology
Municipal works refer to urban operating mechanism construction project, and in China, urban operating mechanism refers to being built in metropolitan district, town (township) planning
If being arranged in range, based on government responsibility and the voluntary various buildings for providing paid or free public product and service for resident
Object, structures, equipment etc..The mating various public infrastructure developments of urban life belong to municipal works scope, than as usual
The urban road seen, bridge, subway, for example, with the various pipelines that are closely related of life:Rainwater, sewage, upper water, middle water, electric power,
Telecommunications, heating power, combustion gas etc., also square, the construction in gardens etc. belong to municipal works scope.
During Municipal Engineering Construction, sand is as one of most common construction material, in actual use, due to city
The technology requirement of political affairs construction, needs to sieve sand, to obtain more fine and smooth, that grain size is smaller sand, at present
Municipal construction Sand screen it is poor to the screening effect of sand, screening process needs hand feed mostly, and the amount of labour is larger, and
Inefficiency is unfavorable for current municipal construction demand.

Specific implementation mode
The technical solution of this patent is described in more detail With reference to embodiment:
- 3 are please referred to Fig.1, a kind of municipal works Sand screen, including control box 1,1 top of control box are installed with support
Frame 3, rotary type is equipped with runner 4 on support frame as described above 3, and rotary type is arranged with the limit of the first position-limited wheel 2 and second on supporting rack 3
Wheel 7, is equipped with the first drawstring 10 between the first position-limited wheel 2 and the second position-limited wheel 7,10 runner of the first drawstring, 4 front is eccentric fixed
Positioning column 5 is installed, positioning column 5 is equipped with lantern ring 6 in upper movable sleeve, and 10 upper end of the first drawstring is fixed on lantern ring 6, operates
Two feed hoppers 8 are arranged on case 1, horizontal slidingtype is equipped with sliding panel 9 on feed hopper 8, and 9 upper surface of sliding panel is fixed vertically
Upper vertical plate 12 is installed, 1 inner top of control box is installed with lower riser 20 vertically, fixed between lower riser 20 and upper vertical plate 12
It is connected with resetting spring 21, the symmetrical rotary type of 1 inner top of the control box is equipped with fixed pulley II19, is arranged on fixed pulley II19
Second drawstring 18,18 one end of the second drawstring are fixed on 9 end of sliding panel, and 18 other end of the second drawstring and the first drawstring 10, which are fixed, to be connected
It connects, is equipped with screening slot 17 in the control box 1, rotary type is equipped on 17 or so lateral wall of screening slot supports with 1 madial wall of control box
The guide roller 16 connect is installed with postive stop baffle 14 in the control box 1, fixed between postive stop baffle 14 and screening slot 17
It is connected with resetting spring 15;Fixed pulley I11 is equipped with by holder pivots formula inside the control box 1, the first drawstring 10 passes through downwards
It wears screening slot 17 and bypasses fixed pulley I11, the first drawstring 10 is fixed on 17 bottom surface of screening slot far from 6 one end of lantern ring.
The application method and operation principle of the present invention.
The sand sieved is placed in feed hopper 8 when use, runner 4 is turned under the drive of driving motor
Dynamic, runner 4 drives lantern ring 6 to rotate by positioning column 5, and lantern ring 6 drives the first drawstring 10 to pull screening slot 17 in resetting spring 15
Elastic acting force under pump, the first drawstring 10 drive sliding panel 9 resetting spring 21 elastic acting force bottom left
The right side reciprocatingly slides, and when sliding panel 9 is to the first 10 1 Slideslip of drawstring, 21 deformation of resetting spring compression, 8 lower end of feed hopper goes out
Mouth gap increases, and when sliding panel 9 is to 8 one Slideslip of feed hopper, 21 deformation of resetting spring restores former long, and sliding panel 9 is extend into
Part in feed hopper 8 is increased, and the outlet gap reduction of 8 lower end of feed hopper at this time closes feed hopper 8 up to sliding panel 9, sliding
The reciprocating sliding of movable plate 9 realizes that sand intermittence is fallen under feed hopper 8 in screening slot 17, avoids under sand excessively concentrates
It falls in screening slot 17, realizes the abundant screening of sand.
In conclusion the present invention realizes that the first drawstring 10 moves up and down by the rotation of runner 4, and then drive screening slot 17
The up-down vibration under the elastic acting force of resetting spring 15 promotes the shaking of sand in screening slot 17, substantially increases sand
Screening speed;The left and right of sliding panel 9 reciprocatingly slides, and realizes intermittent blanking of the sand from feed hopper 8, avoids sand mistake
It is dropped into screening slot 17 in concentration, the screening of sand is more fully completely.
