Description
Technical Field
The utility model relates to a wax matrix sand-lined technical field especially relates to the centrifugal sand spreader of belt.
Background
The wax pattern casting comprises a sand coating process, namely, the prepared wax pattern is coated with molding sand, and a sand shell, namely a mould for casting, is formed after drying; in the prior art, a sand coating process or a sand blowing process is adopted, namely, molding sand falls onto a wax mold from the upper part, or an air blower blows up the molding sand in a container to turn over the molding sand, so that the passing wax mold is coated with the sand; these two kinds of modes all can produce a large amount of dust, seriously pollute workshop environment, bring the injury for workman's health, and these two kinds of modes all are that the molding sand freely falls on the wax matrix simultaneously, so the compactness and the efficiency of cover sand are not high, often need carry out the multilayer and cover sand, and the sand shell that forms is also very thick.
Disclosure of Invention
An object of the utility model is to prior art not enough, and provide the centrifugal sand spreader of belt, it spills the molding sand through the belt feeder, makes the molding sand be stained with the wax matrix under steerable speed on, improved sand-lined efficiency, simultaneously, the dust that this mode produced is also very little.
The utility model provides a technical scheme that its technical problem adopted is: centrifugal sand spreader of belt, including connecing the sand box, connect the top of sand box uncovered, the top left and right sides that connects the sand box respectively is provided with a belt feeder, the belt feeder upwards extends to from both sides slope connect the top of sand box, the bottom that connects the sand box is provided with the lifting machine, the top of lifting machine is provided with down the hopper, the bottom of hopper respectively is connected with a slant shakeout passageway about to, the export of shakeout passageway hang in the top of belt feeder.
Furthermore, the sand receiving box is provided with a dust collector.
Further, the elevation angle of the belt conveyor is 30 degrees.
Further, the belt both sides of belt feeder are provided with the backplate that prevents the blanking, the backplate with the belt of belt feeder has the clearance, the bottom of backplate is provided with keeps off the material brush.
Further, the bottom surfaces of the two shakeout channels form a sharp corner at the intersection of the tops.
The utility model has the advantages that: centrifugal sand spreader of belt, it is including connecing the sand box, connect the top of sand box uncovered, the top left and right sides that connects the sand box respectively is provided with a belt feeder, the belt feeder upwards extends to from both sides slope connect the top of sand box, the bottom that connects the sand box is provided with the lifting machine, the top of lifting machine is provided with the blanking fill, the bottom of blanking fill respectively is connected with a slant shakeout passageway about to, the export of shakeout passageway hang in the top of belt feeder. The belt feeder to connect the top of sand box to shed the grit to make the grit hit with certain speed connect the wax matrix on the wax matrix line on the sand box, thereby cover sand fast, simultaneously, the utility model discloses the dust of production is few, has improved workshop production environment.

Detailed Description
The following detailed description of the present invention is provided in connection with the accompanying drawings and the embodiments, and is not intended to limit the scope of the invention.
As shown in fig. 1-4, the centrifugal belt sand spreader of the present embodiment includes a sand receiving box 1, the top of the sand receiving box 1 is open, two belt conveyors 2 are respectively disposed on the left and right sides of the top of the sand receiving box 1, the belt conveyors 2 extend obliquely upward from both sides to the top of the sand receiving box 1, a lifting machine 3 is disposed at the bottom of the sand receiving box 1, a blanking hopper 4 is disposed at the top of the lifting machine 3, a downward inclined sand falling channel 5 is respectively connected to the bottom of the blanking hopper 4 from left to right, and an outlet of the sand falling channel 5 is suspended above the belt conveyors 2.
The utility model discloses when using, can carry out totally closed from the outside, and the wax matrix production line that will carry out the cover sand passes from the utility model discloses the left and right sides, promptly the wax matrix production line is in belt feeder 2 with pass this sand spreader between shakeout passageway 5, like this, when the molding sand on belt feeder 2 is spilled out when rotating, the molding sand hits the wax matrix under certain speed, and this speed can be adjusted through adjusting the speed of belt feeder 2, has improved the efficiency of cover sand greatly, and has reduced the number of piles and the sand shell thickness of cover sand, has improved the molding sand utilization ratio; in addition, the dust generated by the invention is little, and the dust collector 6 is arranged on the sand receiving box 1, so that the generated little dust can be sucked away, and the workshop environment is well improved.
The included angle between the belt conveyor 2 and the ground can be adjusted within the range of 20-45 degrees, and according to practice, the efficiency of casting molding sand and sand coating by the belt is the best when the included angle is 30 degrees. In order to prevent from falling from the shakeout passageway the grit on the belt feeder 2 is unrestrained, the belt both sides of belt feeder 2 are provided with backplate 7, there is the clearance between backplate 7 and the belt, the bottom of backplate 7 is provided with keeps off the material brush 8, the bottom of belt feeder 2 also is provided with and spanes the horizontal baffle of belt feeder 2.
The bottom surfaces of the two shakeout channels 5 form a sharp corner where the tops meet. Thus, the molding sand in the lower hopper 4 is not accumulated and can smoothly fall down.
It should be finally noted that the above embodiments are only intended to illustrate the technical solutions of the present invention, and not to limit the scope of the present invention, and although the present invention has been described in detail with reference to the preferred embodiments, it should be understood by those skilled in the art that the technical solutions of the present invention can be modified or replaced with equivalents without departing from the spirit and scope of the technical solutions of the present invention.
