Description

A kind of new sand sieving machine
Technical field:
The utility model is related to Casting Equipment technical field, more particularly to a kind of new sand sieving machine.
Background technology:
Cast in sand casting, it is necessary to use sand, the fineness of sand is related to the precision of product after casting, In existing sand screening installation, typically all screened using vibratory sieve, screening efficiency is poor, and screening effect is not Very well, easy impurity after screening, influences end product quality.
Utility model content:
The utility model provides a kind of new sand sieving machine, solves that screening efficiency in the prior art is low, and screening effect is poor Technical problem.
Technology solution of the present utility model is as follows:A kind of new sand sieving machine, includes and is installed on workbench, workbench It is sequentially installed with upwards in organic frame, frame on multiple guide rails, each guide rail and a screening frame is installed, screening frame bottom is installed There is pulley, pulley is embedded in guide rail, a screen cloth, screening frame bottom and screening frame side wall are fixed with screening frame and positioned at sieve The top of net forms a discharging opening, also includes drive mechanism, and drive mechanism includes two installed on the table Individual motor, each motor output shaft end is provided with a cam, also includes and is connected with one on two first connecting rods, each cam It is also associated with a connecting plate, each screening frame being connected with a second connecting rod on individual first connecting rod, first connecting rod, second connects Bar is connected with connecting plate.
Preferably, guide rail quantity is 3.
Preferably, cam is disc cam.
Preferably, guide rail is in horizontally disposed.
Preferably, motor is stepper motor.
The beneficial effects of the utility model are:In the utility model, sand to be screened is placed into frame most In that high screening frame, then in the presence of motor, two motors do counter motion, and cam is reversely rotated, cam Drive first connecting rod, first connecting rod drive connection plate, connecting plate driving second connecting rod, second connecting rod driving screening frame, so that real Now to the front and rear stretching of screening frame, so as to realize that the screening to sand forms discharging opening because each screening frame bottom, screen Sand afterwards is dropped in next screening frame, and large granular impurity is rolled out out of discharging opening on the wall of screening frame side, so as to realize Hierarchical screening, the utility model is simple in construction, realizes hierarchical screening, it is ensured that product quality, improves operating efficiency.
Brief description of the drawings:
Fig. 1 is the utility model structural representation.
In figure:1st, workbench;2nd, connecting plate;3rd, screening frame;4th, guide rail;5th, cam;6th, motor;7th, second connecting rod;8th, One connecting rod.
Embodiment:
With reference to a kind of new sand sieving machine of 1 pair of this practicality of accompanying drawing, it is described further.
A kind of new sand sieving machine, includes to install on workbench 1, workbench 1 and is sequentially installed with upwards in organic frame, frame One screening frame 3 is installed, the bottom of screening frame 3 is provided with pulley, and pulley is embedded in guide rail 4 on multiple guide rails 4, each guide rail 4 It is interior, a screen cloth, the bottom of screening frame 3 and the side wall of screening frame 3 are fixed with screening frame 3 and one is formed positioned at the top of screen cloth Individual discharging opening, also includes drive mechanism, and drive mechanism includes two motors 6 on workbench 1, each motor 6 Output shaft end is provided with a cam 5, also includes and is connected with a first connecting rod 8 on two first connecting rods 8, each cam 5, It is also associated with a connecting plate 2, each screening frame 3 being connected with a second connecting rod 7 on first connecting rod 8, second connecting rod 7 is with connecting Fishplate bar 2 is connected.
Specifically, the quantity of guide rail 4 is 3, can carry out hierarchical screening, lifts screening efficiency.
Specifically, cam 5 is disc cam, and the driving first connecting rod 8 of cam 5 is moved.
Specifically, guide rail 4 is in horizontally disposed so that screening frame 3 carries out level screening.
Specifically, motor 6 is stepper motor, can effectively control breakneck acceleration, improves screening effect.
Operation principle of the present utility model is:In the utility model, sand to be screened is placed into highest in frame That screening frame 3 in, then in the presence of motor 6, two motors 6 do counter motion, and cam 5 is reversely rotated, convex Wheel 5 drives first connecting rod 8, the drive connection plate 2 of first connecting rod 8, the driving second connecting rod 7 of connecting plate 2, the driving screening of second connecting rod 7 Frame 3, so that the front and rear stretching to screening frame 3 is realized, so as to realize that the screening to sand is formed because of each bottom of screening frame 3 Discharging opening, the sand after screening is dropped in next screening frame 3, and large granular impurity is out of, discharging opening on the side wall of screening frame 3 Roll out, so as to realize hierarchical screening.
Preferred embodiment of the present utility model is the foregoing is only, those of ordinary skill in the art are not making creativeness The every other embodiment obtained under the premise of work, should all belong to the scope of the utility model protection.
