It can effectively clean and recycle some defective products and then reprocess them, which not only improves the quality of castings but also realizes the recycling and utilization of resources.

[0003] At present, when a crusher crushes automobile parts, the crushing effect may be poor, resulting in some larger crushed objects. Due to their large volume, these larger crushed objects may block the equipment inlet when entering the next process, such as magnetic separation, eddy current separation or melting, increasing energy consumption and even damaging the equipment. Moreover, the existing device cannot screen the crushed automobile parts, resulting in the need to select the crushed objects again later, increasing a certain amount of workload.

[0004] In view of this, it is necessary to design a crushing device for casting sand molds of automobile parts that can screen to solve the above problems. Content of the Utility Model

The fixed frame 4 is fixedly connected to the housing 2 by welding. Two crushing rollers 5 are rotatably arranged on the fixed frame 4. The right side of the fixed frame 4 is fixedly connected with the mounting bracket 6 by bolt connection. The first motor 7 is installed on the mounting bracket 6. The output shaft of the first motor 7 is connected to the front crushing roller 5. Gears 8 are installed on the left sides of both crushing rollers 5, and the two gears 8 mesh with each other. It further includes a cam 9, a pressing rod 10, a limiting collar 1001, a sliding frame 11, a filter screen 12, a baffle 13, a transmission frame 14, an aggregate box 15, and an elastic member 16. The cam 9 is fixedly connected to the right side of the rear crushing roller 5 by welding. The sliding frame 11 is slidably arranged on the housing 2. The filter screen 12 is fixedly connected to the sliding frame 11 by welding. The baffle 13 is fixedly connected to the front side of the filter screen 12 by welding, and the front side of the sliding frame 11 is inclined downward. The pressing rod 10 is installed on the right side of the sliding frame 11. The limiting collar 1001 is fixedly connected to the right side of the housing 2 by welding, and the pressing rod 10 is slidably connected to the limiting collar 1001. A plurality of elastic members 16 are arranged between the sliding frame 11 and the housing 2. The transmission frame 14 is fixedly connected to the right side of the housing 2 by welding, and an opening corresponding to the transmission frame 14 is provided on the housing 2. The aggregate box 15 is installed on the rear side of the housing 2, and the transmission frame 14 is connected to the aggregate box 15.

[0025] Refer to as Figure 5 and Figure 6 As shown in the figure, it further includes a support frame 17, a collection frame 18, a second motor 19, a flip plate 20, and an electromagnet 21. The support frame 17 is fixedly connected to the installation frame 1. The collection frame 18 is fixedly connected to the support frame 17 by welding. The flip plate 20 is rotatably arranged on the collection frame 18. Electromagnets 21 are installed on both sides of the flip plate 20. The second motor 19 is installed on the support frame 17. The output shaft of the second motor 19 is connected to the flip plate 20.

[0026] Refer to as Figure 7 As shown in the figure, it further includes an electric slide rail 22, a sliding frame 23, and a partition box 24. The electric slide rails 22 are installed on both sides of the installation frame 1. The sliding frame 23 is arranged on the two electric slide rails 22. The partition box 24 is placed on the sliding frame 23.

[0027] When this device needs to be used, start the first motor 7 through the control panel 3. The first motor 7 rotates, causing the crushing roller 5 to rotate. The crushing roller 5 drives the gears 8 to mesh with each other, causing the crushing roller 5 on the other side to rotate. Then, place the automotive parts to be crushed onto the two rotating crushing rollers 5. The two crushing rollers 5 rotate to crush the automotive parts. When the crushed automotive parts fall, the rotation of the crushing roller 5 drives the cam 9, and the cam 9 presses the extrusion rod 10 downward. The downward pressing of the extrusion rod 10 causes the sliding frame 11 to be pressed downward, and at the same time, applies pressure to the elastic member 16, causing it to deform. When the cam 9 is no longer in contact with the extrusion rod 10, the elastic member 16 returns to its original state, causing the sliding frame 11 to move upward. This process repeats, causing the sliding frame 11 and the filter screen 12 to continuously move up and down. When the automotive parts fall onto the filter screen 12 on the sliding frame 11, due to the front side of the sliding frame 11 being inclined downward, the smaller crushed automotive parts will fall through the filter screen 12, while the larger automotive parts will fall onto the baffle 13 along the slope. Moreover, the continuous up and down movement of the sliding frame 11 and the filter screen 12 vibrates the larger automotive parts onto the transmission rack 14, and then they slide from the transmission rack 14 into the inside of the aggregate box 15. When the smaller automotive parts fall onto the electromagnets 21 on both sides of the turning plate 20, energize the electromagnets 21 to make the electromagnets 21 adsorb the smaller automotive parts. After adsorbing the smaller automotive parts, start the second motor 19 to make the turning plate 20 rotate by an appropriate angle, and then stop supplying power to the electromagnets 21, causing other objects such as sand and gravel to fall forward and into the separation box 24. Then start the second motor 19 to make the turning plate 20 rotate and reset. When the inside of the separation box 24 is full, energize the electric slide rail 22 to make the sliding frame 23 slide forward. The sliding of the sliding frame 23 drives the separation box 24 to move forward, carry out the separation box 24, and then clean the inside of the separation box 24. After the separation box 24 is cleaned, put it back on the sliding frame 23, and then drive the sliding frame 23 through the electric slide rail 22 to send the separation box 24 back to its original position. This process repeats. When the automotive parts are crushed, then close the first motor 7 through the control panel 3 to stop the rotation of the crushing roller 5.

[0028] Refer to as Figure 1 and Figure 3 shown, it also includes a protective shell 26 and a push plate 27. A groove 25 is opened on the separation box 24. The protective shell 26 is installed on the left side of the fixed frame 4, and the protective shell 26 encloses the two gears 8. The push plate 27 is slidably arranged on the transmission rack 14.

[0029] The groove 25 opened on the separation box 24 can facilitate lifting the separation box 24. The protective shell 26 can protect the gears 8 to prevent obstacles from affecting the operation when the gears 8 are rotating. The push plate 27 can push the larger fragments of automotive parts accumulated on the transmission rack 14 onto the aggregate box 15.

[0030] The above are only embodiments of the present utility model, and thus do not limit the patent scope of the present utility model. Any equivalent structure or equivalent process transformation made by using the content of the specification of the present utility model, or directly or indirectly applied in other related technical fields, shall similarly be included within the patent protection scope of the present utility model.
