Description

Technical Field

[0001] This utility model relates to the technical field of waste crushing, specifically a waste crusher for water conservancy and hydropower projects. Background Technology

[0002] Hydraulic and hydropower engineering is an engineering science that regulates and utilizes water energy resources through engineering or non-engineering measures based on the study of the natural characteristics of water. During the construction of hydropower projects, excess waste is generated, such as engineering slag and engineering waste. When treating hydraulic waste, a hydraulic waste crusher is needed to crush the waste.

[0003] An existing patent, CN220277083U, describes a crusher for hydraulic waste. It consists of a secondary crushing chamber, a screen, and springs. Hydraulic waste falls onto the top of the screen, pushing the screen plate downwards. A moving frame compresses the springs, causing small waste particles to fall through the screen holes. The springs cause the screen to vibrate up and down, improving the screening effect. Larger waste particles slide down the screen to the top of an inclined plate and enter the secondary crushing chamber. A motor drives a fine crushing roller via a transmission belt and drive wheel, further crushing the larger hydraulic waste particles and improving the overall crushing efficiency.

[0004] However, this device relies solely on two fixed sets of meshing gears for the transmission of the crushing roller, making maintenance inconvenient and reliability poor. Utility Model Content

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Example

[0024] Please see Figure 1-4A waste crusher for water conservancy and hydropower projects includes a casing 1, rotating shafts 2, and crushing rollers 3. A set of rotating shafts 2 are rotatably mounted on the left and right sides inside the casing 1. The outer wall of each set of rotating shafts 2 is connected to the inner wall of a set of crushing rollers 3. The machine also includes a drive motor 4, a reducer 5, a rear limiting plate 6, a polygonal prism 7, an external threaded head 8, a nut 9, a tightening plate 10, a gear 11, and a polygonal groove 12. One rear end of the casing 1 is connected to the inner side of the reducer 5. The output end of the drive motor 4 is connected to the input end of the reducer 5. The output end of the reducer 5 is connected to the rear side of a set of rotating shafts 2. Both sets of rotating shafts 2 extend forward inside the casing 1. The front end of each set of rotating shafts 2 is connected to the middle of the rear side of a set of rear limiting plates 6. The middle of the front side of the rear limiting plate 6 is connected to the rear end of the polygonal prism 7. The front end of the polygonal prism 7 is connected to the rear end of the external threaded head 8. The outer side of 8 and the inner side of nut 9 are detachably screwed together. A tightening plate 10 is connected to the rear side of nut 9. A multi-faceted groove 12 is provided in the middle of gear 11. The multi-faceted groove 12 is movably fitted on the outer side of the multi-faceted prism 7. During installation, the two sets of gears 11 can be movably fitted on the outer side of the corresponding multi-faceted prism 7 through the multi-faceted groove 12 and limited by the rear limit plate 6. Then, the screw-on nut 9 is rotated on the outer side of the corresponding external thread head 8 so that the tightening plate 10 connected to the nut 9 supports and limits the front side of the gear 11, thereby completing the relative fixation of the rotating shaft 2 of the two sets of gears 11 meshing with each other. During operation, the drive motor 4 acts on the reducer 5 to drive one set of rotating shaft 2 to rotate, and under the fixed condition, the two sets of gears 11 mesh and rotate in opposite directions, thereby driving the other set of rotating shaft 2 to act on the crushing roller 3 to rotate, so that the waste placed in the machine housing 1 can be crushed by the two sets of crushing rollers 3 rotating in opposite directions.

[0025] It also includes internal threaded grooves 13, mounting screws 14, and handles 15. Each set of gears 11 has two sets of internal threaded grooves 13 facing each other on the outer side. The inner wall of the internal threaded groove 13 is detachably screwed to the outer wall of the mounting screw 14. The outer side of the mounting screw 14 is connected to the middle of the inner side of the handle 15. When the mounting screw 14 is screwed into the internal threaded groove 13 on the gear 11, the handle 15 can be fixed relative to the gear 11. Thus, holding the two sets of handles 15 can connect the movement of the gear 11, improving convenience.

[0026] It also includes an information engraving 16, which is provided on one side of the outer end of the gear 11; the information of the gear 11 can be displayed through the information engraving 16, making it easy to distinguish and use, and improving convenience.

[0027] It also includes a hinge 17, a protective cover 18, and a connecting frame 19. The front exterior of the housing 1 is connected to the rear side of the connecting frame 19. The lower front end of the connecting frame 19 is movably connected to the rear inner end of the protective cover 18 via the hinge 17. Under the constraint of the hinge 17, the protective cover 18 can be opened and closed relative to the connecting frame 19. When the protective cover 18 is open, it is convenient to perform installation, inspection, and maintenance operations on the internal structure. When the protective cover 18 is closed, it can work together with the connecting frame 19 to protect the structure and improve reliability.

[0028] It also includes a shaft 20, a throttle 21, a moving pin holder 22, a shaft movable sleeve 23, and a fixed pin 24. The inner side of the middle front of the protective cover 18 is connected to the outer side of the shaft movable sleeve 23. The inner wall of the shaft movable sleeve 23 is rotatably connected to the outer wall of the shaft 20. The outer end of the shaft 20 is connected to one side of the inner end of the throttle 21. The inner end of the shaft 20 is connected to one side of the inner end of the moving pin holder 22. The fixed pin 24 is connected to the upper middle front side of the inner side of the connecting frame 19. When the protective cover 18 is closed, the throttle 21 can be turned to rotate the shaft 20 in the shaft movable sleeve 23, thereby causing the moving pin holder 22 to rotate and be inserted into the fixed pin 24, thus closing and fixing the protective cover 18 and improving stability.

[0029] It also includes an inner frame 25 and a filter screen 26. The inner side of the bottom of the protective cover 18 is connected to the outer side of the inner frame 25, and the filter screen 26 is connected to the inner side of the inner frame 25. The inner frame 25 can provide ventilation and heat dissipation when the protective cover 18 is closed, and the filter screen 26 filters external impurities, thereby improving reliability.

[0030] In summary, when using a waste crusher for water conservancy and hydropower projects, during installation, the appropriate gear 11 is selected according to the information engraving 16. The screw rod 14 is rotated and installed within the internal thread groove 13 of the gear 11, fixing the handle 15 relative to the gear 11. This allows the two sets of handles 15 to be connected to the movable gear 11. The two sets of gears 11 can be movably fitted onto the outer side of the corresponding polygonal prism 7 via the polygonal groove 12, and limited by the rear limit plate 6. Then, the screw nut 9 is rotated on the outer side of the corresponding external thread head 8, causing the top clamping plate 10 connected to the nut 9 to support and limit the front side of the gear 11. This completes the relative fixation of the rotating shaft 2 of the two sets of gears 11 meshing with each other. During operation, the drive motor 4, acting on the reducer 5, drives one set of rotating shaft 2 to rotate, and under fixed conditions... Two sets of gears 11 mesh and rotate in opposite directions, thereby driving another set of rotating shafts 2 to rotate the crushing rollers 3. This crushes the waste material placed in the housing 1 through the opposing rotation of the two sets of crushing rollers 3. Under the constraint of the hinge 17, the protective cover 18 can be opened and closed relative to the connecting frame 19. When the protective cover 18 is open, it is convenient to perform installation, inspection and maintenance operations on the internal structure. When the protective cover 18 is closed, it can work together with the connecting frame 19 to protect the structure. When the protective cover 18 is closed, the handle 21 can be turned to rotate the shaft 20 in the shaft movable sleeve 23, thereby causing the moving pin frame 22 to rotate and pin into the fixed pin plate 24, closing and fixing the protective cover 18. The inner frame 25 allows for ventilation and heat dissipation inside and outside after the protective cover 18 is closed, and the filter screen 26 filters external impurities, improving reliability.

[0031] The drive motor 4 and the reducer 5 are commercially available devices known to those skilled in the art. We are simply using them here without making any structural or functional improvements, and we will not elaborate further on them here.

[0032] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
