[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0023] See also Figure 1-5 A sand-falling machine capable of crushing sand clumps comprises a machine body 1, an inclined screen plate 2 is fixed on the inner side of the machine body 1, a partition plate 6 is fixedly connected to the inner side of the machine body 1, a through slot 7 is provided on the partition plate 6, a fixing hole 8 is provided between two through slots 7 on the partition plate 6, a swing mechanism is provided in the fixing hole 8, a crushing mechanism is rotatably connected in the machine body 1, the crushing mechanism comprises a clamping plate 12, a communicating fixed pipe 4 is connected to the clamping plate 12, an upper end of the fixed pipe 4 is fixedly connected to an exhaust pipe 5, and the other end of the exhaust pipe 5 is fixedly connected to a vacuum cleaner.
[0024] Specific working principle and implementation method: the casting wrapped with molding sand is placed on the screen plate 2 of the machine body 1, and the machine body 1 is turned on and starts to vibrate. The casting and the molding sand will separate during the vibration, and the fallen large pieces of molding sand will enter the back side of the partition 6 through the lower end of the through groove 7. The large pieces of molding sand will contact the clamping plate 12. As the machine body 1 vibrates, the large pieces of molding sand will continuously collide with the clamping plate 12, and the clamping plate 12 rotates inside the machine body 1. As the machine body 1 vibrates, the clamping plate 12 swings up and down, thereby Large pieces of molding sand are clamped into small particles and fall down from the sieve plate 2 and discharged, and when they hit the molding sand, the dust inside is driven by the vacuum cleaner to be sucked out to the outside through the exhaust pipe 5; the advantage of such a design is that the casting and large pieces of molding sand are separated by the partition plate 6, and the separated molding sand is clamped and reduced by the continuous vibration of the swinging clamping plate 12, so that the molding sand on the upper end of the sieve plate 2 can smoothly fall to the lower end of the machine body 1 for discharge, and the dust of the crushed molding sand is discharged through the vacuum cleaner, so as to achieve the effect of purifying the internal environment.
[0025] like Figure 5 As shown, the rocking mechanism includes a rocking arm 9, the end of which is fixedly connected to a connecting rod 10, and a limit buckle 11 is penetrated on the back side of the connecting rod 10 located on the partition 6; as the body 1 vibrates, the connecting rod 10 and the rocking arm 9 are driven to swing up, down, left and right, and the limit buckle 11 is used to limit the connecting rod 10 and the rocking arm 9 from falling off, and the operation is convenient, the rocking arm 9 can prevent the casting from being close to the partition 6, and prevent the casting from blocking the molding sand from passing through the groove 7, and the rocking arm 9 vibrating up, down, left and right can hit large pieces of molding sand, so that the molding sand can pass through the groove 7.
[0026] like Figure 4As shown, one end of the splint 12 is rotatably connected to the inner side of the body 1 close to the screen plate 2, the upper end of the splint 12 away from the rotating end is fixedly connected to a fixing plate 13, the upper end of the fixing plate 13 is fixedly connected to a spring 14, the upper end of the body 1 is fixedly connected to a cover plate 3 by screws, and the cover plate 3 is fixedly connected to the spring 14; the upper end of the spring 14 is fixed to the inner end of the cover plate 3, and the cover plate 3 is fixed to the body 1 by screws. When the body 1 vibrates, the spring 14 is relatively still, and the cover plate 3 vibrates with the body 1 and then pulls the spring 14. The spring 14 stretches the splint 12 with its own elastic force to vibrate up and down with the rotating end as the center. As the angle becomes smaller and smaller, the block shape of the molding sand becomes smaller and smaller. As the screen plate 2 is tilted, the molding sand can be better crushed.
[0027] like Figure 4 As shown, the number of springs 14 is set to be multiple, and the spacing between the springs 14 is set to be equal; multiple springs 14 can make the clamping plate 12 swing up and down more balanced, so that the clamping efficiency of the clamping plate 12 is higher and the crushing efficiency is higher.
[0028] like Figure 5 As shown, the outer diameter of the connecting rod 10 is smaller than the inner diameter of the fixing hole 8. The connecting rod 10 is located inside the fixing hole 8 and can swing in a wider range through the gap, thereby making the swing amplitude of the rocker arm 9 larger and the impact force of the rocker arm 9 with the molding sand greater; the effect of breaking large pieces of molding sand is better.
[0029] like Figure 5 As shown, the outer end of the rocker 9 is rounded; the rounded corners at the end of the rocker 9 prevent the surface of the casting from being worn when swinging.
[0030] like Figure 5 As shown, the fixing holes 8 are arranged vertically, and the spacing between the fixing holes 8 is equal; the position of the rocker 9 can be adjusted according to the size of the casting, so that the rocker 9 can swing and hit the sand balls of different sizes, thereby improving the efficiency and practicality of the crushing.
[0031] The above description is only a preferred embodiment of the present invention and does not constitute any form of limitation to the present invention. Although the present invention has been disclosed as a preferred embodiment as above, it is not intended to limit the present invention. Any technical personnel in this field can make some changes or modify the technical contents disclosed above into equivalent embodiments without departing from the scope of the technical solution of the present invention. However, any simple modification, equivalent change and modification made to the above embodiments based on the technical essence of the present invention without departing from the content of the technical solution of the present invention still fall within the scope of the technical solution of the present invention.
