Description

Technical Field

[0001] This utility model relates to the field of shredding machine technology, specifically a dual-drive biomass resource shredding machine. Background Technology

[0002] Biomass resource reuse refers to the process of converting organic matter (such as crop straw, forestry waste, livestock and poultry manure, food processing waste, etc.) into energy, materials, or high-value-added products through physical, chemical, or biological technologies. When processing biomass resources such as crop straw, the first step is to shred the biomass resources using a shredder.

[0003] In the prior art, a shredder with publication number CN210449416U includes a frame, a shredding chamber, a hopper, a moving cutter roller, a drive mechanism, and a fixed cutter. This shredder also includes chip removal units located at both ends of the shredding chamber parallel to the extension direction of the moving cutter roller. Each chip removal unit includes a baffle parallel to a side wall of the shredding chamber perpendicular to the extension direction of the moving cutter roller, and a gap between the baffle and the side wall of the shredding chamber. A bearing seat is located on the side of the baffle away from the shredding chamber, and a bearing is embedded in the bearing seat. The end of the moving cutter roller shaft can pass through the shredding chamber axially and then sequentially through the gap and the baffle before being inserted into the bearing. This shredder, by setting a gap, prevents a small amount of shredded material falling from the gap between the roller shaft and the side wall of the shredding chamber during operation from directly entering the bearing. Instead, it enters the gap and eventually falls to the ground, effectively preventing shredded material from entering the bearing and extending its service life.

[0004] However, while this type of shredder can perform a good tearing operation on materials, it often uses a single shredding roller to tear the materials. This results in a low double tearing effect within the shredder, reducing the thoroughness of material crushing. At the same time, the patting and unblocking effect on the discharge screen is not high after long-term use, and the large pieces of debris can easily cause blockage on the surface of the discharge screen, reducing the material discharge speed.

[0005] Therefore, in view of this, we have studied and improved the existing structure to address its shortcomings, and proposed a dual-drive biomass resource shredder. Utility Model Content

[0006] The purpose of this utility model is to provide a dual-drive biomass resource shredder to solve the problems mentioned in the background art, such as the low dual shredding effect of materials in the shredder, the reduced crushing of materials in the shredder, and the low patting and unblocking effect of the discharge screen after long-term use.

A reduction gearbox is provided at one end of the first transmission belt. A second three-phase asynchronous motor is provided on the outer wall of the tearing machine body, and a second transmission belt is fixedly connected to the output end of the second three-phase asynchronous motor and fixedly connected to the rotation center of the rolling scraper.

[0009] Furthermore, the first transmission belt is fixedly connected to the input shaft of the gearbox, and the coupling body is fixedly connected to the output shaft of the gearbox.

[0010] Furthermore, the first tearing tooth and the second tearing tooth are arranged in opposite directions of rotation, and the surface of the first tearing tooth is provided with eight teeth.

[0011] Furthermore, the side toothed rows are symmetrically arranged on both sides of the rolling scraper, and the swing toothed plates are arranged in a straight line on the outer wall of the rolling scraper.

[0027] like Figures 1-3 As shown, a first three-phase asynchronous motor 3 is provided on the outer wall of the tearing machine body 1. A first transmission belt 4 is fixedly connected to the output end of the first three-phase asynchronous motor 3. A reduction gearbox 5 is provided at one end of the first transmission belt 4. A second three-phase asynchronous motor 11 is provided on the outer wall of the tearing machine body 1. A second transmission belt 12 is fixedly connected to the output end of the second three-phase asynchronous motor 11 and fixedly connected to the rotation center of the rolling scraper 13, which plays the role of driving the first tearing tooth 7 and the rolling scraper 13 to rotate in a dual-drive manner.

[0028] like Figure 2 As shown, the first transmission belt 4 is fixedly connected to the input shaft of the reduction gearbox 5, and the coupling body 6 is fixedly connected to the output shaft of the reduction gearbox 5. The fixed connection between the first transmission belt 4 and the input shaft of the reduction gearbox 5 facilitates the rotation of the first tearing tooth 7.

[0029] like Figure 4 As shown, the first tearing tooth 7 and the second tearing tooth 10 are arranged in opposite directions of rotation, and the surface of the first tearing tooth 7 is provided with eight teeth, which is beneficial to fully tearing biological resources by means of the opposite rotation directions of the first tearing tooth 7 and the second tearing tooth 10.

[0030] like Figure 3 As shown, the side toothed rows 14 are symmetrically arranged on both sides of the rolling scraper 13, and the swing toothed plates 15 are arranged in a straight line on the outer wall of the rolling scraper 13. This arrangement of the side toothed rows 14 on both sides of the rolling scraper 13 further enhances the tearing effect on biological resources.

[0031] like Figure 5As shown, a discharge screen 16 is provided at the bottom of the shredding machine body 1, and a servo motor 17 is provided on the outer wall of the shredding machine body 1.

Through the meshing connection of the drive gear 8 and the connecting gear 9, the second shredding tooth 10 is driven to rotate, thus playing a role in the initial shredding of biological resources (crop straw, weeds, etc.). At the same time, the second three-phase asynchronous motor 11 is turned on and connected to the second transmission belt 12, driving the rolling scraper 13 to rotate. Under the action of the side tooth row 14, the initially shredded biological resources are further shredded.

[0034] Finally, when discharging the fully shredded biological resources through the discharge screen 16, in order to prevent the mesh holes on the surface of the discharge screen 16 from becoming clogged, the servo motor 17 is turned on, and the rotation of the threaded rod 18 drives the threaded slide rod 19 to slide along the outer wall of the shredder body 1. The rotation of the pull rod 20 drives the striking rod 21 to slide along the inner wall of the slide groove 22, performing a reciprocating relative striking motion on the surface of the discharge screen 16, thereby reducing the clogging of the mesh holes on the surface of the discharge screen 16.
