The lower part of the low-speed bag breaking and crushing roller 6 is equipped with a material cleaning device a8, which is a slat with a concave groove hole, and the crushing blade a10 of the roller extends into the concave groove hole, and cooperates with it, the material cleaning device a8 There is a gap between the concave slot and the crushing blade a10 of the roller extending into the slot, and the number of concave slots matches the number of rows of the crushing knife assembly a7.

The basic structure of the high-speed bag-breaking and crushing roller 9 in this device is the same as that of the above-mentioned low-speed bag-breaking and crushing roller 6. The broken bag crushing roller 6 is opposite, and the material cleaning device b38 is arranged on its right side, and is fixed on the cabinet 2 .

The shifting roller 20 is paired with the high-speed bag-breaking and crushing roller 9. The two rollers rotate in the same direction. An eccentric roller 21 is installed inside the shifting roller 20. A slider 22 and a shifting rod 23 are installed on the outer circumference of the eccentric roller 21. The material rod 23 is connected with the slide block 22 .

The crushing knife assemblies of the above-mentioned high-speed bag-breaking roller 9 and the low-speed bag-breaking roller 6 are arranged in seven rows according to the axial direction, and the driving rods 23 of the feeding roller 20 are arranged in six rows according to the axial direction, and the high-speed bag-breaking roller The crushing blades between the cylinder 9 and the low-speed bag-breaking roller 6 are arranged oppositely, and the crushing blades 30 of the high-speed bag-breaking roller 9 and the material rods 23 of the material roller 20 are arranged in a staggered manner.

Among Fig. 6, dodge device 15 is the side plate that is hingedly connected in cabinet 2 tops, comprises compression spring 16, avoids bent plate 17, tension spring 18, has seven pairs of dodged bent plates 17 to be hinged at the bottom of dodged device 15.

In this device, the rotating speed of the low-speed bag-breaking and crushing roller 6 is 5-60 rpm, the rotating speed of the high-speed bag-breaking and crushing roller 9 is 10-120 rpm, and the rotating speed of the feeding roller 20 is 5-80 rpm. Minutes, the speed difference between the high-speed bag-breaking crushing roller 9 and the shifting roller 20 is 1-20.

There is a certain distance between each row of crushing knife assemblies on the rollers of the low-speed bag-breaking and crushing roller 6 and the high-speed bag-breaking and crushing roller 9, and the crushing knife assemblies are equally divided on the circumference of the roller; There is a certain distance between the rods 23, and the rods 23 are equally divided on the circumference of the drum.

The crushing blade on the crushing knife assembly of the device is made of high-quality alloy steel material, and the crushing knife assembly, crushing blade and material shifting rod are all detachable and replaceable.

The working process of this embodiment is as follows: After the material enters from the feed port 3, it is first crushed by the low-speed bag-breaking roller 6. When the crushing blade a10 is breaking the bag, it encounters bricks, tiles, stones, ceramic glass, etc. in the garbage. , batteries and other unbreakable bulky hard materials, the avoidance curved plate 17 hinged on the avoidance device 15 first retreats, and the stretch spring 18 deforms and stretches; when the retreat of the avoidance curved plate 17 cannot allow the object to pass, then avoid The device 15 retreats, and the compression spring 16 of the avoidance device 15 deforms and compresses; when the retreat of the avoidance curved plate 17 and the avoidance device 15 cannot allow objects to pass through, the crushing blade a10 automatically rotates toward the roller axis with the return spring pin 11 as the center of the circle A certain angle and close up. Make the crushing blade a10 avoid the material and let the material pass through smoothly; when the material passes through, under the action of the return spring 12 in the crushing knife assembly a7, the crushing blade a10 automatically rotates back to its original position. Avoid bending plate 17, avoiding device 15 and crushing blade a10 return to original position under the effect of spring force. This avoids the over-breaking of unbreakable large hard materials such as bricks, tiles, stones, ceramic glass, batteries, etc. in the garbage, reduces the difficulty of sorting in the subsequent process, and facilitates the recycling and utilization of various resources in the garbage; secondly , to form a certain protection for the broken blade a10, prolonging its service life.

At the lower part of the low-speed bag-breaking and crushing roller 6, a cleaning device a8 is installed to clean the fiber materials wound on the crushing blade a10 of the low-speed bag-breaking and crushing roller 6, and make the fiber materials wound on the low-speed bag-breaking and crushing roller 6 Plastic bags and bulk organic materials are further crushed, and also play a role in blocking materials coming down from the feeding port 3.

The high-speed bag-breaking and crushing roller 9 performs further bag-breaking and crushing on the bag-broken garbage that has been broken by the low-speed bag-breaking and crushing roller 6, which is convenient for subsequent processing. The cleaning device b38 installed on the right side of the high-speed bag-breaking and crushing roller 9 is used to clean the entanglement on the crushing blade b30 installed on the high-speed bag-breaking and crushing roller 9 .

The shifting roller 20 is paired with the high-speed bag-breaking and crushing roller 9. When the shifting roller 20 rotates, the shifting rod 23 rotates with the rotation of the shifting roller 20, and the rotation of the shifting rod 23 drives the sliding The block 22 slides along the outer circumference of the eccentric roller 21, and the eccentricity of the eccentric roller 21 enables the poking rod 23 to expand and contract along the radial direction of the cylinder. Take away plastic bags in the rubbish, winding materials and bricks and tiles, ceramic glass, batteries and other unbreakable bulk hard materials when the material rod 23 is stretched out. When the material rod 23 is retracted, the material rod 23 The entanglement on it is automatically detached.

In this way, through the first bag breaking of the low-speed bag breaking and crushing roller 6, the large pieces of organic matter are crushed to a certain extent while the garbage in the bag is dispersed, and the automatic avoidance device 15 and the bag breaking and crushing blade 10 make the large, hard Inorganic matters pass through directly without being crushed; the high-speed bag-breaking roller 9 breaks the garbage bags that are insufficiently broken by the low-speed bag-breaking roller 6 again, and at the same time selectively crushes the garbage again to make large pieces of organic matter Obtain crushing; the expansion and contraction of the material rod 23 in the material material roller 20 picks away the plastic bag after the bag is broken, the flexible material and the bulk inorganic matter in the rubbish. Finally, the organic matter in the garbage is discharged from the organic matter discharge port 5, and the inorganic matter is discharged from the inorganic matter discharge port 4, thereby achieving the purpose of bag breaking, crushing and sorting of garbage.
