Description

Technical Field

[0001] The present invention relates to the technical field of environmental protection engineering equipment, and in particular to solid waste treatment equipment for environmental protection engineering. Background Art

[0002] Solid waste treatment, whose full name is solid waste disposal, usually refers to the process of converting solid waste into materials suitable for transportation, storage, utilization or disposal through physical, chemical, biological, physicochemical and biochemical methods. The goal of solid waste treatment in environmental protection projects is to make it harmless, reduce its volume and utilize it as a resource. Generally, it is necessary to crush the solid waste first to facilitate transportation and disposal.

[0003] The existing solid waste treatment equipment for environmental protection projects generally puts the solid waste into a crushing box, and crushes it through two crushing rollers in the crushing box. Since the solid waste in environmental protection projects varies in shape and size, its position cannot be adjusted after entering the crushing box. When the contact area between the solid waste and the two crushing rollers is small, the crushing rollers need to spend a lot of time to crush it, which can easily cause solid waste congestion on the top of the crushing rollers, thereby reducing the efficiency of solid waste treatment.

[0013] The working principle and beneficial effects of the present invention are:

[0014] 1. By setting a material dividing mechanism, when the solid waste is crushed, the second drive motor is started, and the output end of the second drive motor drives the second reciprocating screw to rotate, thereby driving the sliding plate to reciprocate along the direction of the second rectangular limit rod, thereby driving the push plate to reciprocate horizontally to flatten the solid waste accumulated in one place, so that the solid waste can be spread between the two crushing rollers, thereby improving the solid waste crushing effect;

[0015] 2. By setting up the cooperation of the connecting spring and other parts, when the push plate encounters a hard object during the lateral movement, the push plate will slide relative to the sliding plate briefly and squeeze the connecting spring, so that the sliding plate can buffer when encountering obstacles, so that it can stop briefly, so that the two crushing rollers can crush the hard object, thereby reducing the greater wear caused during the operation of the equipment;

[0016] 3. By setting a material-dispensing mechanism, when the second reciprocating screw rotates in a circle, it drives the pulley to rotate, and then drives the belt to drive another pulley to drive another first reciprocating screw to rotate in a circle, thereby driving the slider to drive the first connecting plate to move back and forth horizontally, thereby pushing the solid waste on the slope, so that in the process of cooperating with the push plate to move horizontally, the first connecting plate moves relatively, and the position of the long waste can be calibrated so that it can lie flat on the two crushing rollers, thereby increasing the contact area between the long workpiece and the crushing roller, thereby improving the crushing effect of the solid waste;

[0017] 4. By setting up the coordination of parts such as spur racks, the first connecting plate drives the rectangular slide bar to move while performing the horizontal reciprocating movement. When the roller contacts the power block, when the roller moves from the lowest point of the power block to the highest point, the roller pushes the rectangular slide bar to drive the spur rack to move toward the second spur gear, thereby driving the second spur gear to drive the swing rod to rotate through the second rotating shaft, so that the swing rod can swing toward the outside of the first connecting plate, so as to perform oblique pushing, which is conducive to the long strips of solid waste placed on the slope to slide down obliquely;

[0018] 5. By arranging the cooperation of parts such as strong torsion springs, when the first connecting plate drives the two swing rods to reset, if there is an obstacle between the two and the reset is resisted, the second rotating shaft drives one end of the strong torsion spring to rotate, thereby causing the strong torsion spring to twist, so as to ensure the normal operation of the equipment. Since the swing rod can rotate 120 degrees to an inclined state, the obstructed solid waste can slide down from the middle, thereby further improving the overall practicality of the device.

The material-discharging mechanism includes a first connecting plate 21 arranged on the slope 7. The material-discharging mechanism includes a fixed seat 9 fixedly connected to both sides of the material guide box 2. The inner side of the fixed seat 9 is rotatably connected with a first reciprocating screw 8. A slider 10 is installed on the outer wall of the first reciprocating screw 8.

The inner side of the slider 10 is provided with a crescent pin matching the first reciprocating screw 8.

[0038] When the second reciprocating screw 18 rotates in a circle, it drives the pulley 19 to rotate, and then drives the belt 20 to drive another pulley 19 to drive another first reciprocating screw 8 to rotate in a circle, thereby driving the slider 10 to drive the first connecting plate 21 to move back and forth laterally, thereby pushing the solid waste on the slope 7, so that in the process of cooperating with the push plate 15 to move laterally, the first connecting plate 21 moves relatively, and the position of the long waste can be calibrated so that it can lie flat on the two crushing rollers 12, thereby increasing the contact area between the long workpiece and the crushing roller 12, thereby improving the crushing effect of the solid waste.

[0039] Embodiment 3: An oblique push assisting device for obliquely pushing materials accumulated on the slope 7 is arranged on the inner side of the first connecting plate 21, and the oblique push assisting device comprises a connecting shell 31 fixedly connected to the top of the first connecting plate 21, and two second rotating shafts 34 are rotatably connected to the inner side of the connecting shell 31, and a connecting shaft 37 is rotatably connected to the bottom of the second rotating shaft 34, and the connecting shaft 37 is fixedly connected to the swing rod 29, and a strong torsion spring 13 is installed on the top of the connecting shaft 37 and the inner side of the second rotating shaft 34, and the oblique push assisting device also comprises a second spur gear 35 fixedly connected to the outer wall of the second rotating shaft 34, and a rectangular slide bar 24 is slidably connected to the inner side of the connecting shell 31, and the rectangular slide bar 24 One end of the second connecting plate 32 is fixedly connected to the inside of the connecting shell 31, and spur racks 36 meshing with the second spur gear 35 are fixedly connected to the two sides of the second connecting plate 32. An auxiliary spring 33 is fixedly connected to the inner side of the second connecting plate 32, and one end of the auxiliary spring 33 is fixedly connected to the connecting shell 31. The other end of the rectangular slide bar 24 passes through the outside of the connecting shell 31 and is rotatably connected to the roller 25. The top of the guide box 2 is fixedly connected to the fixing plate 22, and the inner side of the fixing plate 22 is fixedly connected to the power block 23. The power block 23 is set to an arch shape, and a plurality of power blocks 23 are provided, and the plurality of power blocks 23 are equidistantly distributed on the inner side of the fixing plate 22;

[0040] The first connecting plate 21 moves back and forth laterally while driving the rectangular slide bar 24 to move. When the roller 25 contacts the power block 23 and moves from the lowest point of the power block 23 to the highest point, the roller 25 pushes the rectangular slide bar 24 to drive the spur rack 36 to move in the direction of the second spur gear 35, thereby driving the second spur gear 35 to drive the swing rod 29 to rotate through the second rotating shaft 34, so that the swing rod 29 can swing toward the outside of the first connecting plate 21, so as to be able to push obliquely, which is conducive to the long strips of solid waste placed on the slope 7 to slide down obliquely.

[0041] When the rectangular slide bar 24 moves to the maximum distance, the swing bar 29 rotates 120 degrees. When the roller 25 moves from the highest point of the power block 23 to the lowest point, the rectangular slide bar 24 can be reset under the action of the auxiliary spring 33.

[0043] When the first connecting plate 21 drives the two swinging rods 29 to reset and there is an obstacle between them causing resistance to their reset, the second rotating shaft 34 drives one end of the strong torsion spring 13 to rotate, thereby causing the strong torsion spring 13 to twist, thereby ensuring the normal operation of the equipment. Since the swinging rod 29 can rotate 120 degrees to an inclined state, the obstructed solid waste can slide down from the middle, thereby further improving the overall practicality of the device.

[0044] Working principle:

[0045] First, when the solid waste for environmental protection projects enters the guide box 2 and slides onto the crushing roller 12 through the ramp 7, the first drive motor 3 is started, and the output end of the first drive motor 3 drives the first rotating shaft 6 to rotate, and then drives another first rotating shaft 6 to rotate through the first spur gear 5, so that the two crushing rollers 12 rotate relative to each other to crush the solid waste;

[0046] When the solid waste is crushed, the second drive motor 16 is started, and the output end of the second drive motor 16 drives the second reciprocating screw 18 to rotate, thereby driving the sliding plate 14 to reciprocate along the direction of the second rectangular limit rod 26, thereby driving the push plate 15 to reciprocate horizontally to flatten the solid waste accumulated in one place, so that the solid waste can be spread between the two crushing rollers 12, thereby improving the solid waste crushing effect;

[0047] When the push plate 15 encounters a hard object during the lateral movement, the push plate 15 will slide relative to the sliding plate 14 briefly and squeeze the connecting spring 30, so that the sliding plate 14 can buffer when encountering obstacles, thereby reducing the greater wear caused during the operation of the equipment;

[0048] The push plate 15 , the rectangular contraction block 28 , the rectangular frame 27 , and the connecting spring 30 can also be arranged symmetrically on the other side of the sliding plate 14 about the central axis of the sliding plate 14 , which is not shown in the drawings.

[0049] When the second reciprocating screw 18 rotates in a circle, it drives the pulley 19 to rotate, and then drives the belt 20 to drive another pulley 19 to drive another first reciprocating screw 8 to rotate in a circle, thereby driving the slider 10 to drive the first connecting plate 21 to move back and forth horizontally, thereby pushing the solid waste on the slope 7, so that in the process of cooperating with the push plate 15 to move horizontally, the first connecting plate 21 moves relatively, and the position of the long waste can be calibrated so that it can lie flat on the two crushing rollers 12, thereby increasing the contact area between the long workpiece and the crushing roller 12, thereby improving the crushing effect of the solid waste;

[0050] The first connecting plate 21 moves back and forth laterally while driving the rectangular slide bar 24 to move. When the roller 25 contacts the power block 23 and moves from the lowest point of the power block 23 to the highest point, the roller 25 pushes the rectangular slide bar 24 to drive the spur rack 36 to move in the direction of the second spur gear 35, thereby driving the second spur gear 35 to drive the swing rod 29 to rotate through the second rotating shaft 34, so that the swing rod 29 can swing toward the outside of the first connecting plate 21, so as to be able to push obliquely, which is conducive to the long strips of solid waste placed on the slope 7 to slide down obliquely.

[0051] When the rectangular slide bar 24 moves to the maximum distance, the swing bar 29 rotates 120 degrees. When the roller 25 moves from the highest point of the power block 23 to the lowest point, the rectangular slide bar 24 can be reset under the action of the auxiliary spring 33. The setting of multiple power blocks 23 can realize the continuous reciprocating movement of the swing bar 29, thereby improving the overall practicality of the device.

[0052] When the first connecting plate 21 is in the initial position and when it moves to the maximum position, there is always a distance between the first connecting plate 21 and the inner side of the material guide box 2, thereby avoiding material jamming;

[0053] When the first connecting plate 21 drives the two swinging rods 29 to reset and there is an obstacle between them causing resistance to their reset, the second rotating shaft 34 drives one end of the strong torsion spring 13 to rotate, thereby causing the strong torsion spring 13 to twist, thereby ensuring the normal operation of the equipment. Since the swinging rod 29 can rotate 120 degrees to an inclined state, the obstructed solid waste can slide down from the middle, thereby further improving the overall practicality of the device.

[0054] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
