Scheme 2 is further improved on the basis of scheme 1 and obtains: being equipped on the crank and extends along its length
Dovetail groove, the pouring weight are equipped with the guide pad cooperated with the dovetail groove guiding movement.
Scheme 3 is further improved on the basis of scheme 1 or 2 and obtains: upper interval is set along its length on the crank
Casing there are two setting, the driving lead screw is installed in described sleeve pipe to be rotatably assorted with the crank.
Scheme 4 is further improved on the basis of scheme 1 or 2 and obtains: being equipped on the crank and is used to indicate the pouring weight
The indicating graduation of position.
Scheme 5 is further improved on the basis of scheme 1 or 2 and obtains: the operation structure is hand wheel structure.
The beneficial effects of the utility model are: in use, material is placed in screening cylinder, since crank is equipped with weight
Block, driving motor generate the vibration force in multiple directions during rotation and vibration force are transmitted to screening by connecting component
On cylinder, so that the material in screening cylinder is sieved by filter screen, finally flowed out from corresponding discharging structure, when for difference
Material when being sieved, need to adjust the vibrational state of vibrating motor, pass through operation structure rotate driving lead screw, driving at this time
Lead screw drives pouring weight to move on crank under the action of thread matching structure, so that position of the pouring weight on crank obtains
Adjustment, so that the rotary state of vibrating motor is also adjusted, and the position of pouring weight is adjusted using nut screw driving mechanism
It is simple to set structure, adjusts easy to operate.
Further, pouring weight is cooperated by the dovetail groove on guide pad and crank, and structure is simple, and dovetail groove is with anti-
De- function, improves reliability.
Further, driving lead screw is rotatably assorted by casing and crank, and structure is simple, and cost reduces.

Specific embodiment
The utility model is further described with reference to the accompanying drawings and examples.
The embodiment 1 of the shaking screen of the utility model, as shown in Figure 1 to Figure 3, a kind of shaking screen, including pedestal 1 and set
The screening cylinder 2 on pedestal 1 is set, is arranged at intervals with two layers or more of filter screen 4, screening in the inner cavity of screening cylinder 2 up and down
Cylinder 2 is equipped with discharging structure 6 corresponding with filter screen 4, sieves and is connected with vibrating motor 8 by connecting component 11 on cylinder 2,
The both ends of the power output shaft 21 of vibrating motor 8 are mounted on crank, and two cranks are respectively top crank according to upper and lower position
10 and lower crank 9.Top crank is identical with the structure of lower crank, includes corresponding crank body, in crank body 22
