Abstract
Description
Technical Field
[0001] The invention belongs to the technical field of casting equipment, and mainly relates to a sand block crushing device for a sand falling machine, which is used for improving the efficiency of the sand falling operation in the sand regeneration link of the casting industry. Background Art
[0002] In the sand casting process, after the molding and pouring are completed, the foundry sand needs to be recycled and reused. Since it contains resin and curing agent, the foundry sand retained after the casting molding and pouring is in block form. When recycling, the sand blocks are mainly transported to the vibrating sand shakeout machine by a loader, and the sand shakeout machine is used to vibrate up and down to break the sand blocks, and then the sand is regenerated. However, since some sand blocks are large and hard, they cannot be crushed and recycled in a short time by the vibrating sand shakeout machine. The sand shakeout machine can only be vibrated continuously until the sand blocks are broken, which significantly reduces the working efficiency of the sand shakeout machine and wastes energy. Summary of the invention
[0003] In order to overcome the shortcomings of the prior art, the present invention provides a sand block crushing device for a sand shaker. By adding a sand block crushing device to the sand shaker, the sand blocks can be quickly crushed, the working efficiency of the sand shaker can be significantly improved, and the energy consumption can be significantly reduced.
[0004] A sand block crushing device for a sand falling machine, the crushing device comprises a pressure plate, a bracket, a hoisting motor, and a steel wire rope; the pressure plate is tiltedly arranged above the vibration platform of the sand falling machine, the pressure plate comprises a first surface and a second surface arranged opposite to each other, the first surface faces the vibration platform, and the first surface is provided with a plurality of protrusions; the second surface is provided with a lifting lug; a pulley is fixed above the bracket; the bracket is arranged between the hoisting motor and the pressure plate; the steel wire rope is wound on the drum of the hoisting motor, and the steel wire rope passes through the pulley and is fixedly connected to the lifting lug; wherein the hoisting motor, the pressure plate, and the bracket are all arranged on the same horizontal plane.
[0005] Among them, the hoisting motor rotates forward and reverse to realize the tightness of the wire rope, that is, the hoisting motor tilts and pulls the pressure plate through the wire rope; when the hoisting motor relaxes the wire rope until the pressure plate contacts the vibration platform of the sand falling machine, the sand blocks are crushed by the raised blocks provided on the pressure plate, and then the wire rope is pulled to pull up the pressure plate, and the above operation process is repeated until the sand blocks on the vibration platform are broken.
[0006] In one of the embodiments, the pressing plate is hingedly arranged above the vibrating platform of the sand shakeout machine through a flip support.
[0007] In one of the embodiments, a fulcrum ear is provided at one end of the second surface away from the ear, and the fulcrum ear is mounted with the flip support via a pin.
[0008] In one of the embodiments, the pressure plate is rotatably arranged along the pin shaft.
[0009] In one of the embodiments, the rotation range of the pressure plate is 0° to 90°; if the rotation angle of the pressure plate is greater than 90°, the pressure plate will fall onto the vibration platform when the hoisting motor relaxes the wire rope.
[0010] In one embodiment, the exposed end of the protruding block is a spike-like structure, which makes it easier to break up the sand block and improve the working efficiency of the sand shaker.
[0011] In one embodiment, the crushing device also includes a support frame. When the pressure plate is in a pulled-up state, the support frame is placed under the pressure plate to support the pressure plate and prevent the pressure plate from falling or sliding down, which facilitates other operations.
[0012] In one of the embodiments, a limit plate is fixedly provided on the side of the bracket; in order to prevent the pressure plate from being unable to be released and fall down after being pulled up beyond 90°, a reasonable angle is pre-set and a limit plate is fixedly provided on the side of the bracket, so that the pressure plate will not be pulled beyond 90°.
[0013] The present invention provides a sand block crushing device for a sand shaking machine. The sand block crushing device is added to the sand shaking machine. When in use, the hoisting motor is turned on, the hoisting motor pulls up a pressure plate, and then the recovered casting sand blocks are added to the vibration platform of the sand shaking machine. At this time, the sand shaking machine is started, and at the same time, the hoisting motor loosens the wire rope to drop the pressure plate. This operation is repeated, and the recovered casting sand blocks are crushed by the vibration of the sand shaking machine, the dead weight of the pressure plate and the raised blocks on the pressure plate, thereby achieving rapid crushing of the sand blocks, thereby significantly improving the efficiency of the sand shaking link and reducing the purchase amount of new sand; in addition, the effective startup time of the equipment is reduced, and energy consumption is reduced.
