Description

Technical Field

[0001] This utility model relates to the field of shredding equipment technology, specifically a four-axis dual-motor shredder. Background Technology

[0002] The four-axis dual-motor shredder is a high-efficiency solid waste treatment equipment, consisting of four sets of independent shearing rollers. It adopts a dual-motor drive system to enhance the shearing force. The blades adopt an interlaced design, and the shearing and tearing forces are generated by the reverse rotation of the rollers. It can effectively process materials such as metal drums, waste tires, and hard plastics. The equipment is equipped with an adjustable screen to control the output size. It features a large crushing chamber, high crushing ratio, and high crushing efficiency. It is widely used in the crushing and treatment of industrial waste, domestic waste, and other fields.

[0003] Chinese patent CN218250663U discloses a four-axis shredder for solid waste. Through the cooperation of a limiting block and a spring, the spring promptly resets the movable rod due to vibrations generated by the shredder during operation, preventing the filter screen from loosening. Simultaneously, the cooperation between the limiting prism on the movable rod and the limiting through groove and limiting slot in the fixed groove allows for easy installation and removal of the filter screen, greatly facilitating its cleaning. Rollers at the bottom of the support slide facilitate pushing or pulling the filter screen into or out of the mounting slot. A discharge conveyor belt facilitates the removal of the shredded waste.

[0004] The filter screen of the above patent has a fixed installation position, and the distance between the filter screen and the shredding roller cannot be adjusted according to different shredding needs. It cannot control the output particle size, nor can it adapt to the characteristics of different materials. It cannot adjust the distance between the filter screen and the shredding roller according to the hardness, toughness, size and shape of different materials. Utility Model Content

[0005] The purpose of this utility model is to provide a four-axis dual-motor shredder. By extending the extension bar to the upper end of the corresponding suspension bar according to different spacing requirements, the extension piece is attached to the front end of the suspension bar and then bolted through the extension piece and embedded in the fixing hole. This can fix the sliding extension bar. After fixing, the distance between the cutter shaft and the filter screen can also be directly adjusted and fixed, thus solving the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a four-axis dual-motor shredder, comprising a base, four blade shafts horizontally arranged in the middle of the base, a filter screen at the lower end of each blade shaft, and a mounting frame welded around the lower end of the filter screen. Extension strips are provided at both ends of the mounting frame, and six suspension strips are evenly distributed longitudinally at one end of each of the two extension strips. A fixing hole is provided on one side of each suspension strip, and an extension piece is provided on the side outside the fixing hole. The extension piece is fixedly connected to the corresponding fixing hole inside the suspension strip by bolts. After the extension strip corresponding to the filter screen slides to the upper end of the suspension strip, it facilitates the fixing of the mounting frame and the filter screen, making it suitable for different shredding needs.

[0007] Preferably, the extension piece is welded and fixed to the extension strip. The extension piece limits the sliding distance of the extension strip and also facilitates the passage of bolts to complete the fixation.

[0008] Preferably, a protective plate is provided on one side of the mounting frame. The protective plate is connected to the base slot, and the protective plate can also be used to wrap and protect the mounting frame.

[0009] Preferably, the protective plate is fixedly connected to the outer wall of the base by bolts. The bolts passing through the protective plate facilitate its fixation to the base surface, making it easy to disassemble and install the protective plate, as well as to replace the filter screen.

[0010] Preferably, the mounting frame has a recessed movable cavity on the outside facing the fixing hole. The reserved movable cavity can accommodate the longitudinal sliding of the suspension strip, which facilitates the adjustment of the horizontal position and height of the filter screen.

[0011] Preferably, the upper end of the base is provided with a feeding frame. The reserved feeding frame can help to gather the material after it is put in, so that the material can be sent into the device to contact the rotating cutter shaft.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] Before the filter screen is wrapped around the lower ends of the four cutter shafts, this invention fixes the filter screen by sliding the extension strip to the upper end of the suspension strip at the corresponding horizontal height, according to the required distance between the filter screen and the cutter shafts. This facilitates adjustment of the distance between the filter screen and the cutter shafts, as well as easy installation and removal of the filter screen. After the mounting frame slides to the upper end of the suspension strip via the extension strip, the extension piece at the front end of the extension strip will fit against the front end of the suspension strip. The mounting frame and filter screen can be fixed after installation by bolting through the extension piece and embedding it into the fixing hole. This facilitates adjustment of the filter screen and also makes it easy to fix the adjusted filter screen, adapting to different pulverizing needs. Attached Figure Description

[0021] The present invention will be further described below with reference to specific embodiments.

[0022] like Figure 1 and Figure 2 As shown, a four-axis dual-motor shredder of this embodiment includes a base 1, and a feeding frame 2 is provided at the upper end of the base 1. The feeding frame 2 can collect the material inside the upper feeding device, which facilitates the material transfer and feeding into the base 1.

[0023] Furthermore, four blade shafts 3 are horizontally arranged in the middle of the interior of the base 1. The rotation of the blade shafts 3 can crush the material falling from above, such as... Figure 6 As shown, each of the four cutter shafts 3 is equipped with a transmission gear 13 at one end. The two transmission gears 13 on the two sides of the middle inside the base 1 are connected by an output gear 12. The rotation of the output gear 12 can drive the transmission gears 13 to rotate respectively. A motor is provided at one end of the output gear 12. The motor can drive the cutter shaft 3 to rotate. The simultaneous rotation of the cutter shaft 3 can contact and crush the material falling from the top.

[0024] It is worth mentioning that, in order to ensure that the crushed material can be crushed to the corresponding particle size before falling, a filter screen 10 is provided at the lower end of the cutter shaft 3. A mounting frame 5 is provided around the lower end of the filter screen 10, and the mounting frame 5 is welded and fixed to the filter screen 10. Extension strips 7 are provided at both ends of the mounting frame 5, which facilitates the installation of the mounting frame 5.

[0025] In this embodiment, in order to suspend the protruding extension bar 7, six suspension bars 6 are evenly distributed longitudinally at one end of each of the two extension bars 7, and the suspension bars 6 are welded and fixed to the inner wall of the base 1. The protruding suspension bars 6 make it easy for the mounting frame 5 with the extension bars 7 to be suspended at the lower end of the cutter shaft 3.

[0026] The six longitudinally evenly distributed suspension strips 6 are spaced further apart than the thickness of the extension strip 7. The extension strip 7 can slide laterally between two suspension strips 6. A fixing hole 9 is provided on one side of each suspension strip 6. Figure 3 As shown, an extension piece 8 is provided on one side outside the fixing hole 9, and the extension piece 8 is welded and fixed to the extension strip 7. The extension piece 8 can limit the maximum sliding distance of the extension strip 7 when it slides into the two suspension strips 6.

[0027] To secure the extension piece 8 and the suspension strip 6, the extension piece 8 and the corresponding fixing holes 9 inside the suspension strip 6 are fixedly connected by bolts. After the extension strip 7 slides and the extension piece 8 adheres to one side of the suspension strip 6, as... Figure 4 As shown, the extension bar 7, the corresponding mounting frame 5, and the filter screen 10 can be fixed by bolts, so that the mounting frame 5 and the filter screen 10 can be fixed to the corresponding height, and the distance between the fixed cutter shaft 3 and the filter screen 10 can be adjusted.

[0028] In this embodiment, a protective plate 4 is provided on one side of the mounting frame 5. The protective plate 4 is connected to the base 1 through a slot. After the mounting frame 5 slides into the base 1, the protective plate 4 can wrap and protect the mounting frame 5. The protective plate 4 is fixedly connected to the outer wall of the base 1 by bolts. The mounting frame 5 and the filter screen 10 can be easily fixed and replaced by disassembling and fixing the protective plate 4.

[0029] To facilitate the sliding of the hanging strip 6 and to allow for adjustments to the filter 10 at different heights, such as... Figure 5 As shown, the mounting frame 5 has a recessed movable cavity 11 facing the fixing hole 9. When the hanging bar 6 is adjusted to a horizontal position, the hanging bar 6 will slide into the movable cavity 11 to prevent the mounting frame 5 from restricting the hanging bar 6 when sliding horizontally, thus avoiding affecting the adjustment of the distance between the cutter shaft 3 and the filter screen 10.

[0030] Working principle: When using the four-axis dual-motor shredder to shred materials, the mounting frame 5 slides into the upper end of the suspension strip 6 through the extension strips 7 at both ends. By sliding to the upper end of different suspension strips 6, the suspension strip 6 and the corresponding mounting frame 5 can be fixed to the lower end of the cutter shaft 3. The sliding position of the extension strip 7 can adjust the distance between the cutter shaft 3 and the filter screen 10. After the distance is adjusted, the bolts pass through the extension piece 8 and are embedded in the fixing hole 9 to fix the extension strip 7. The protective plate 4 faces the bolt fixing position and covers the front end of the mounting frame 5. The bolts pass through the protective plate 4 and are embedded in the base 1 to fix the protective plate 4. At the same time, the motors corresponding to the two output gears 12 are started. The output of the motors drives the output gears 12 to rotate. The rotation of the output gears 12 drives the two meshing transmission gears 13 to rotate. The rotation of the transmission gears 13 can drive the cutter shaft 3 to rotate. The rotation of the four cutter shafts 3 can shred the material. The material passes through the filter screen 10 and finally falls down.
