Description
Technical field
It the utility model is related to molding sand triage techniques field, more particularly to a kind of molding sand sorting mechanism.
Background technology
Molding sand will be used using sand casting in casting industry, the particle diameter of the molding sand typically used is 0.53-
3.35mm, therefore molding sand should be screened before casting starts and filtration treatment.Moulding sand for casting screening plant is to casting
The machine screened with molding sand is made, including screening export is carried out to the molding sand of various rugosity.Use traditional moulding sand for casting
Screening plant, before screening is started, artificially molding sand to be sieved need to be poured on the screen cloth of screening plant, the work of worker is strong
Degree is big, and the efficiency of screening is also low；And need manually to rock molding sand when screening molding sand and screen, manually
Rock manually and occur and rock uneven so as to cause to screen incomplete phenomenon, and automaticity is relatively low, increases type
The work difficulty of sand sieve choosing.
Utility model content
The purpose of this utility model is providing a kind of molding sand sorting mechanism, can realize self-feeding, mitigate the labor of worker
Momentum, improve the efficiency of molding sand screening.
In order to achieve the above object, base case of the present utility model is：Molding sand sorting mechanism, including motor, the first bar,
Second bar, feeding roller, support, the hopper for being shaped as taper and the screen cloth for being horizontally disposed with and being slidably connected on support, it is described to send
Material roller is located at the top of screen cloth；The bottom of the hopper is provided with discharging opening, and the surface of feeding roller offers stock chest vertically, institute
Feeding roller is stated to be located at the underface of discharging opening and block discharging opening；One end of first bar is hinged on the side of screen cloth, separately
One end is hinged with the second bar；Second bar is fixedly connected with the output shaft of motor, and the output shaft of the second bar and motor mutually hangs down
Directly；Rotating shaft is connected with the center of rotation of the feeding roller, rotating shaft is connected with the output shaft of motor by belt.
The operation principle of this base case is：Molding sand to be sieved is put into hopper, starts motor, motor passes through skin
Band drive shaft rotates, and feeding roller together rotates with rotating shaft.When the stock chest on feeding roller turns to the underface of discharging opening,
Molding sand in hopper is fallen into stock chest, and when stock chest turns to lower section, the molding sand in stock chest is under gravity
Fall on screen cloth.While motor driving feeding roller rotates, motor drives the second bar to rotate, and the second bar is driven by the first bar
Screen cloth moves back and forth along support so that the molding sand on screen cloth realizes screening.
The beneficial effect of this base case is：
1st, self-feeding is realized using hopper and feeding roller, is not required to worker and molding sand to be sieved is poured into screening one after another
On the screen cloth of device, the working strength of worker is effectively reduced, improves processing efficiency；
2nd, under the common cooperation of hopper, feeding roller and motor, the molding sand in hopper is periodically fallen into screen cloth, is avoided
It is once excessive toward the molding sand of screen cloth addition so that sorting mechanism can fully sieve molding sand, and screening effect is good；
3rd, swinging back and forth for screen cloth is driven by motor, the screening of molding sand is realized during screen cloth swings back and forth, automatically
Change degree is higher, it is not necessary to manually rocks molding sand and is screened, effectively reduces the labor intensity of worker；
4th, the moving back and forth of screen cloth, the rotation of feeding roller drives by same motor, reduce and make molding sand screening machine
The space of the occupancy of the cost of structure and the mechanism.
Further, in addition to 2 are used for the baffle plate for preventing that molding sand from dropping；The both sides of the support are provided with along short transverse point
The guide groove of cloth；The side of the baffle plate is hinged on the side that screen cloth is distributed along the direction of motion, and opposite side is slidably connected at guide groove
In.During screen cloth moves back and forth, the side of side plate can slide up and down along guide groove, and the setting of side plate increases screen cloth
Area, effectively prevent the molding sand on screen cloth from dropping.And when molding sand is fallen on side plate from stock chest, molding sand can be along side plate
Slide on screen cloth, avoid molding sand from being scattered in outside screen cloth.
Further, the both sides below the screen cloth are rotatably connected to pulley, and the screen cloth is slidably connected at branch by pulley
On frame.Pulley is set, and screen cloth is slided by pulley along guide groove, and the setting of pulley reduces coefficient of friction, is reduced screen cloth and is being transported
The frictional force being subject to during dynamic, extend the service life of screen cloth.
Further, the lower section of the screen cloth is provided with and connects sand hopper, and the bottom for connecing sand hopper is communicated with molding sand delivery line.Molding sand passes through
Screen cloth is sieved, and qualified molding sand is by screen cloth and then falls in sand hopper is connect, and is connect sand hopper Sand and is turned by molding sand delivery line
The external world is moved on to, the molding sand sieved can be collected by molding sand delivery line, it is very convenient.
Further, three are provided with the feeding roller along the circumferentially equally distributed stock chest of feeding roller.Three storings are set
Groove, then when feeding roller rotates one week, feeding roller realizes feeding three times, improves the efficiency of screening.
