Description

Technical Field

[0001] The utility model relates to the field of environmentally friendly building material crushing and processing, in particular to environmentally friendly building material crushing and processing equipment. Background Art

[0002] According to the patent document with the publication number CN 221580744 U, the building materials are crushed by driving the motor to make the two crushing rollers mesh with each other and rotate, and then the building material particles on the filter plate are vibrated by the vibrator, and then the building material particles screened by the filter plate are crushed again;

[0003] When the patent document re-throws the two crushing rollers to screened building material particles, it is still possible that the same size of building material particles will fall on the filter plate again, and then it is necessary to repeatedly put the screened building material particles into the crushing position, which is troublesome. This repetitive crushing will greatly reduce the crushing speed of the building materials. If the building material particles are slightly larger than the sieve holes and cannot be crushed by the two crushing rollers, the building material particles of this size will clog the sieve holes and affect the extraction of the entire crushed building materials, which is very troublesome.

[0027] The utility model is further described below in conjunction with the accompanying drawings:

[0028] like Figure 1-Figure 8 As shown, an environmentally friendly building material crushing and processing equipment includes a protection mechanism 3, a crushing mechanism 1 for initially crushing the environmentally friendly building materials, and a crushing mechanism 2 for screening the crushed environmentally friendly materials.

[0029] In this embodiment: the crushing mechanism 2 includes a crushing box 21, and inclined grinding side walls 22 are provided on both sides of the crushing box 21. The front and rear ends of the crushing box 21 are provided with penetrating grinding guide grooves 23. The front side of the crushing box 21 is provided with a discharge port, and the discharge port is hinged with a guard plate 24. The bottom of the crushing box 21 is provided with an inclined surface for convenient delivery of crushed building materials. The crushing box 21 is used to support the crushing mechanism 1 and the protective mechanism 3, and the guard plate 24 is used to prevent dust from flying during crushing.

[0030] In this embodiment: the crushing mechanism 1 includes a screening mesh plate 15, a support rod is provided in the middle position of the screening mesh plate 15, and the front and rear ends of the support rod are rotatably connected to the inside of the crushing box 21, and arc-shaped grinding plates 16 are fixed at both ends of the screening mesh plate 15. A first crushing wheel 11 and a second crushing wheel 12 are provided inside the protection mechanism 3, and guide columns 13 are fixed at the front and rear ends of the first crushing wheel 11 and the second crushing wheel 12. The ends of the guide columns 13 are rotatably connected to connecting rods 14, and the lower ends of the connecting rods 14 are rotatably connected to the arc-shaped grinding plates 16. A driving mechanism 4 for driving the first crushing wheel 11 and the second crushing wheel 12 to rotate is provided on the rear side of the protection mechanism 3. Support rods for sliding in the grinding guide grooves 23 are provided at the front and rear ends of the arc-shaped grinding plates 16. The lower ends of the connecting rods 14 are sleeved on the support rods extending out of the crushing box 21. The first crushing wheel 11 and the second crushing wheel 12 are rotated to The building materials are crushed, and at the same time, when the first crushing wheel 11 and the second crushing wheel 12 rotate, the two connecting rods 14 on the front and rear sides of the crushing box 21 are driven by the guide column 13 to move up and down alternately, and then the two connecting rods 14 on the front and rear sides of the crushing box 21 drive the two arc-shaped grinding plates 16 to swing up and down with the supporting rod of the screening mesh plate 15 as the center. In this process, the preliminary crushed building materials are screened by the screening mesh plate 15, and the larger particles of building materials will roll to the arc-shaped grinding plates 16 on both sides of the screening mesh plate 15. Then, when the larger particles of splashed materials roll between the arc-shaped grinding plates 16 and the grinding side walls 22, the arc-shaped grinding plates 16 follow the swing of the screening mesh plate 15 to squeeze the larger particles of building materials onto the grinding side walls 22 of the crushing box 21, and then the larger particles of building materials are crushed again.

[0031] In this embodiment: the protection mechanism 3 includes a protection box 31, a feed port is provided at the upper end of the protection box 31, and two relatively arranged flaps 32 are hinged in the feed port, and rubber strips 33 are fixed at the front and rear ends of the top of the flap 32, and the end of the rubber strip 33 away from the flap 32 is fixedly connected to the top of the protection box 31, and a guide outlet is provided at the lower end of the protection box 31, and the guide outlet is located in the middle position of the top of the screening mesh 15, and a support hole for the rotation of the first crushing wheel 11 and the second crushing wheel 12 is provided in the middle position of the protection box 31, and the rubber strip 33 on the protection box 31 is used to pull the top of the flap 32 upward, and then the two flaps 32 are in a relatively horizontal position, so as to avoid splashing when the first crushing wheel 11 and the second crushing wheel 12 inside the protection box 31 crush the building materials, and at the same time, the preliminarily crushed building materials will fall into the middle position of the screening mesh 15 through the guide outlet, and be screened as the two sides of the screening mesh 15 swing.

[0032] In this embodiment: the driving mechanism 4 includes a fixed frame 44, a driving gear 42 is provided at the upper side of the rear end of the first crushing wheel 11, a driving motor 41 for driving the driving gear 42 to rotate is fixedly provided on the fixed frame 44, and driven gears 43 meshing with each other are fixed to the outer sides of one end of the first crushing wheel 11 and the second crushing wheel 12 extending out of the protective box 31, and the driving gear 42 is driven to rotate by the rotating part of the driving motor 41, and the first crushing wheel 11 is driven to rotate by the meshing of the driving gear 42 and the driven gear 43 on the first crushing wheel 11, and at the same time, the two driven gears 43 on the first crushing wheel 11 and the second crushing wheel 12 are meshed with each other, so as to drive the second crushing wheel 12 and the first crushing wheel 11 to rotate in opposition.

[0033] Working principle: When in use, first put the environmentally friendly building materials to be crushed into the feed port of the protection box 31, and then the two flaps 32 of the feed port are flipped toward the inside of the protection box 31. When the building materials are completely inside the protection box 31, the four rubber strips 33 are used to pull the two flaps 32 to flip upwards, and then the feed port of the protection box 31 is closed by the two flaps 32, so as to prevent the building material debris from flying out of the feed port during crushing;

[0034] At this time, the rotating part of the driving motor 41 drives the driving gear 42 to rotate, and the first crushing wheel 11 is driven to rotate by the engagement of the driving gear 42 with the driven gear 43 on the first crushing wheel 11, and at the same time, the two driven gears 43 are engaged with each other to drive the second crushing wheel 12 and the first crushing wheel 11 to rotate in opposition, and then the building materials in the protection box 31 are preliminarily crushed by the first crushing wheel 11 and the second crushing wheel 12, and the preliminarily crushed building materials will fall to the middle position of the top of the screening mesh plate 15 through the outlet of the protection box 31. At this time, one end of the screening mesh plate 15 is lower than the other end, and the building materials on the screening mesh plate 15 will roll to one side thereof, and at the same time, smaller particles of building materials will fall on the lower side of the screening mesh plate 15, and larger particles of building materials will roll between the arc-shaped grinding plate 16 at one end of the screening mesh plate 15 and the grinding side wall 22;

[0035] During this process, as the guide columns 13 at the front and rear ends of the first crushing wheel 11 drive the two connecting rods 14 connected thereto upward, the two connecting rods 14 move upward to allow the two support rods to drive the arc-shaped grinding plate 16 at one end of the screening mesh plate 15 to flip upward. At this time, the arc-shaped grinding plate 16 at one end of the screening mesh plate 15 will press the larger particles of building materials against the grinding side wall 22 on one side of the crushing box 21, and then the arc-shaped grinding plate 16 at one end of the screening mesh plate 15 will continue to flip upward to squeeze and crush the larger particles of building materials. In addition, when the first crushing wheel 11 rotates, the second crushing wheel 12 also drives the corresponding two connecting rods 14 to move downward through the guide columns 13 at its front and rear ends, and then drives the arc-shaped grinding plate 16 at the other end of the screening mesh plate 15 to flip downward, and then provides a thrust for the arc-shaped grinding plate 16 at one end of the screening mesh plate 15 to flip upward.

[0036] When one end of the screening mesh plate 15 turns over to the highest point, as the first crushing wheel 11 and the second crushing wheel 12 continue to rotate, one end of the screening mesh plate 15 is higher than the other end, and the building materials will roll from one end of the screening mesh plate 15 to the other end, and then the building materials will be screened again. At the same time, the building materials with larger particles will roll between the arc-shaped grinding plate 16 at the other end of the screening mesh plate 15 and the grinding side wall 22 on the other side of the crushing box 21;

[0037] Then, as the first crushing wheel 11 and the second crushing wheel 12 continue to rotate, the connecting rod 14 connected to the second crushing wheel 12 begins to move upward. At this time, the arc-shaped grinding plate 16 at the other end of the screening mesh plate 15 pushes the larger particles of building materials against the grinding side wall 22 at the other side of the crushing box 21, thereby squeezing and crushing the larger particles of building materials. The connecting rod 14 connected to the first crushing wheel 11 pushes the arc-shaped grinding plate 16 of the screening mesh plate 15 downward, thereby providing a certain turning thrust for the arc-shaped grinding plate 16 at the other end of the screening mesh plate 15.

[0038] The building materials screened by the screening mesh 15 will fall on the inclined surface at the bottom of the crushing box 21, and will be sent out through the discharge port on the front side of the crushing box 21. At the same time, a protective plate 24 is used at the discharge port to prevent a large amount of dust from flying out of the discharge port.

[0039] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments, and the above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, and these changes and improvements fall within the scope of the utility model to be protected.
