[0030] 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.

[0031] Reference Figure 1-Figure 3The utility model provides an embodiment: a raw material crushing device for processing a resettable fuse, comprising a shell 1, a feeding port 2 is provided at the top of the shell 1, and raw materials are fed into the device through the feeding port 2, a motor 3 is welded to the outer wall of the shell 1, a rotating shaft a4 is fixedly connected to the output shaft of the motor 3, a transmission assembly is fixedly connected to the outer wall of the rotating shaft a4, the transmission assembly comprises two sets of bevel gears a5, a bevel gear b6 is meshed on the outer wall of the bevel gear a5, a rotating shaft b7 is fixedly connected to the inner wall of the bevel gear b6, and a rotating shaft b7 is fixedly connected to the inner wall of the transmission assembly, The outer wall of the rotating shaft b7 is rotatably connected to the inner wall of the shell 1, and the outer wall of the rotating shaft b7 is fixedly connected with a crushing roller 8. The driving motor 3 causes the rotating shaft a4 to drive the bevel gear a5 to rotate, so that the bevel gear b6 drives the rotating shaft b7 to rotate, thereby driving the two groups of staggered crushing rollers 8 to crush the raw materials. The inner wall of the shell 1 is fixedly connected with a rectangular sheet 13, which is stuck in the gap outside the crushing roller 8, and works together to crush the raw materials that fall into it. The inner wall of the shell 1 is fixedly connected with a sieve plate 12, which is placed obliquely to pass the raw materials that have not passed the screening along the The inclined surface slides out, and the inner wall of the shell 1 is elastically connected with the baffle 11 through the return spring 10. One end of the return spring 10 is fixedly connected to the inner wall of the shell 1, and the other end of the return spring 10 is fixedly connected to the bottom end of the baffle 11. The baffle 11 can squeeze the return spring 10 to move downward. At the same time, the elastic force generated by the deformation of the return spring 10 gives the baffle 11 a reverse thrust to reset it. The outer wall of the shell 1 is fixedly connected with the driving wheel 19, and the outer wall of the driving wheel 19 is connected with the chain 18. The driving wheel 19 is started to drive the chain 18 to run, and the chain 18 is reversed. A slider 15 is fixedly connected to the surface, and a receiving trough 14 is fixedly connected to the inner side of the slider 15. A slide groove 9 is opened on the inner wall of the shell 1. The outer wall of the slider 15 is slidably connected to the inner wall of the slide groove 9. The bottom end of the receiving trough 14 contacts the top of the baffle 11. A cross plate is fixedly connected to the top of the baffle 11. Under normal circumstances, the receiving trough 14 squeezes the baffle 11 to lower it, so that the unscreened raw materials can slide into the receiving trough 14. After that, the chain 18 can drive the receiving trough 14 to move up along the slide groove 9, and tilt it to the top to pour the raw materials into the delivery port 2 for secondary crushing.

[0032] Reference Figure 1 and Figure 4 The inner wall of the shell 1 is detachably connected to a collecting bin 16, and a disc 20 is rotatably connected to the outer wall of the collecting bin 16 on an axis. An arc groove 23 is provided on the inner wall of the disc 20, and two groups of blocks 21 are slidably connected to the inner wall of the collecting bin 16. A column block 24 is fixedly connected to the outer wall of the block 21, and the outer wall of the column block 24 is slidably connected to the inner wall of the arc groove 23. Rotating the disc 20 can make the arc groove 23 pull the column block 24 to drive the arc groove 23 to be retracted. A slot 22 is provided on the inner wall of the shell 1, and the outer wall of the block 21 is engaged with the inner wall of the slot 22. The block 21 is retracted and pulled out of the slot 22, and the collecting bin 16 can be taken out of the shell 1 at this time. A handle 17 is fixedly connected to the outer wall of the collecting bin 16.

[0033] Working principle: put the raw materials into the device through the delivery port 2, start the motor 3, make the rotating shaft a4 drive the bevel gear a5 to rotate, and then make the bevel gear b6 drive the rotating shaft b7 to rotate, so that the two sets of crushing rollers 8 interact with each other to crush the raw materials, and the crushed raw materials pass through the screen plate 12, and part of them fall into the collecting bin 16, and the other part slides into the receiving trough 14 with the inclined screen plate 12. At this time, start the driving wheel 19 to drive the slider 15 to lift the receiving trough 14 along the slide 9, lift it to the highest point and then tilt it, and put the raw materials in the receiving trough 14 back into the device through the delivery port 2 for secondary crushing to make the crushing more complete. When the crushed raw materials need to be collected, rotate the disc 20 to make the arc groove 23 drag the column block 24 to slide, and drive the card block 21 to be pulled out of the card groove 22. At this time, the collecting bin 16 can be taken out by the handle 17, which can ensure that the raw materials are completely taken out and will not adhere to the inner wall of the device, and there is no need to clean the inside of the device.
