[0011] Preferably, a plurality of bumps are provided at the bottom of the pulverizing hammer, the bumps are truncated cone-shaped, and the diameter of the bottom of the bump is smaller than the diameter of the top of the bump.

[0012] Preferably, the method for using the building material crushing device comprises the following steps: S1: First, the building material enters the feed port through the feed end, and then enters the crushing chamber and falls on the second bottom plate and the first bottom plate. After a small amount of material enters, the first motor drives the first arm to rotate, thereby driving the I-shaped slider to slide, and then the slide rail and the support seat are lowered, so that the crushing hammer descends to hammer the material. During the descent of the crushing hammer, the roller slides along the guide groove, so that the crushing hammer can rotate, thereby increasing the crushing strength of the material. The material that meets the requirements falls onto the first screen plate through the leak hole. When the crushing hammer rises to the top, the first rack is squeezed by the lifting block to move the first rack, so that the first gear rotates, and then the second rack moves, so that the second arm and the first rotating shaft rotate along the axis of the first rotating shaft, and at the same time, the second rotating shaft and the first rotating shaft are rotated synchronously through the fifth arm and the fourth connecting rod, and then the third arm and the fourth arm rotate, so that the first connecting rod, the second connecting rod and the third connecting rod rotate, so that the blocking block seals the feed port, and at the same time, the first bottom plate and the second bottom plate move inversely to pull the first bottom plate and the second bottom plate out of the range of the crushing chamber, so that the first crushed material falls onto the first screen plate; S2: The second motor drives the magnetic wheel and the first synchronous wheel to rotate, so that the metal is adsorbed on the magnetic wheel, and the metal on the magnetic wheel is dropped off by the unloading plate. The second synchronous wheel and the first synchronous wheel are rotated synchronously by the synchronous belt, thereby driving a crushing wheel and a cam to rotate, so that the first screen plate rotates repeatedly, and the material is screened quickly. The material passing through the first screen plate finally falls to the bottom of the screening chamber. Due to the meshing of the two second gears, the two crushing wheels rotate at the same time, so that the second crushing of the material is realized, and the material after the second crushing falls onto the second screen plate; S3: While the first screen plate rotates repeatedly, the second screen plate rotates synchronously through the synchronization rod, which is convenient for screening the material. The material that does not pass through the second screen plate moves to the bottom of the wedge block. When the second screen plate rotates upward, it can cooperate with the wedge block to squeeze the material, so that the material is crushed and passes through the second screen plate to the bottom of the screening chamber.

[0013] Compared with the prior art, the present invention has the following beneficial effects: In the present invention, through the coordinated use of components such as the hammer crushing mechanism and the feeding mechanism, when the crushing hammer rises to the top, the hammer crushing mechanism and the feeding mechanism cooperate to make the material in the crushing chamber fall onto the first screen plate, and at the same time, the lower opening of the feed end can be sealed to stop feeding, thereby preventing the material that has not been hammered from falling onto the first screen plate when the crushing chamber is opened.

[0014] In the present invention, by using the hammer crushing mechanism and the guide groove in combination, the crushing hammer can be guided when it descends, so that the crushing hammer can descend and rotate along the guide groove, and the cooperating protrusion can improve the crushing efficiency of the crushing hammer on the material.

DETAILED DESCRIPTION

[0017] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technical personnel in this field without creative work are within the scope of protection of the present invention.

[0018] See also Figures 1 to 12 The present invention provides a technical solution: a building material crushing device, including a processing box 1, a screening chamber is provided at the bottom of the processing box 1, a crushing chamber is provided at the top of the processing box 1, the top of the processing box 1 is connected to a feeding mechanism 3, the top of the processing box 1 is connected to a hammer crushing mechanism 2, one side of the bottom of the processing box 1 is connected to an extrusion crushing mechanism 4, one side of the processing box 1 is connected to a magnetic suction component 5, and the magnetic suction component 5 is located above the extrusion crushing mechanism 4.

[0019] A feed port 12 is provided on one side of the top of the processing box 1, and a feed end 121 is connected to one side of the top of the feed port 12. The feed port 12 is connected to the crushing chamber, and two guide grooves 11 formed in a circumferential array are provided on the side wall of the crushing chamber. It should be noted that: the top of the feed end 121 is connected to a vibrating feeder to realize the transportation of building materials, so that the building materials enter the crushing chamber through the feed port 12. The vibrating feeder is a prior art and will not be described in detail here. The guide groove 11 consists of a vertical groove and a spiral groove, and the spiral groove is located below the vertical groove.

[0020] One side of the top of the screening chamber is rotatably connected to the first screen plate 6 tilted downward, one side of the bottom of the screening chamber is rotatably connected to the second screen plate 7 tilted upward, one side of the top of the second screen plate 7 is connected to the synchronization rod 8, and the top of the synchronization rod 8 is rotatably connected to the first screen plate 6. It should be noted that the downward tilt of the first screen plate 6 can make the material slide to the extrusion crushing mechanism 4 for secondary crushing, and the upward tilt of the second screen plate 7 can make the material slide to the rotating end of the second screen plate 7, so that the material can be screened during the sliding process, and the synchronization rod 8 can make the second screen plate 7 and the first screen plate 6 rotate synchronously to achieve a vibration effect, which can speed up the screening of the material.

[0021] The hammer crushing mechanism 2 includes a first motor 21 connected to one side of the top of the processing box 1, a first arm 22 connected to the driving end of the first motor 21, an I-shaped slider 23 rotatably connected to one side of the first arm 22, and a slide rail 24 slidably connected to the I-shaped slider 23. The slide rail 24, the I-shaped slider 23 and the first arm 22 are located inside the part cavity set in the processing box 1. The bottom of the slide rail 24 is connected to a support seat 25. One end of the support seat 25 passes through the processing box 1 and is located inside the crushing cavity. A lifting block 26 is connected to one side of the top of the support seat 25. One side of the bottom of the support seat 25 is rotatably connected to a crushing hammer 27. The crushing hammer 27 is slidably connected to the cavity body of the crushing cavity. Guide rods 272 are provided on both sides of the top of the crushing hammer 27. One end of the guide rod 272 is rotatably connected to a roller 273. The roller 273 is slidably connected to the groove body of the guide groove 11. It should be noted that the part cavity and the crushing cavity are connected through a lifting hole, and the hole body of the lifting hole is slidably connected to the support seat 25, which limits the position of the support seat 25. Limiting protrusions are provided on both sides of the support seat 25, and the limiting protrusions are slidably connected to the groove bodies on both sides of the lifting hole, which further improves the stability of the support seat 25. When the first motor 21 drives the first arm 22 to rotate, the I-shaped slider 23 can slide repeatedly in the slide rail 24, so that the slide rail 24 can be lifted and lowered, thereby realizing the lifting and lowering of the crushing hammer 27. When the crushing hammer 27 descends, the roller 273 slides in the guide groove 11, which can make the crushing hammer 27 rotate while descending, thereby improving the crushing strength of the material.

[0022] In this embodiment, Figures 1 to 12 As shown, the unloading mechanism 3 includes a first rack 31 slidably connected to the top of the processing box 1 and a first gear 32 meshingly connected to one side of the first rack 31, the bottom of the first gear 32 is rotatably connected to the processing box 1, one side of the first gear 32 is meshedly connected to the second rack 33, the bottom of the second rack 33 is slidably connected to the processing box 1, one end of the second rack 33 is rotatably connected to the second arm 34, the bottom of the second arm 34 is connected to the first rotating shaft 35, both ends of the first rotating shaft 35 are rotatably connected to the fixed plate set in the processing box 1, springs 36 are sleeved on both sides of the first rotating shaft 35, and the outer ends of the springs 36 are connected to the fixed plate. It should be noted that: two T-shaped slide grooves are provided on the top of the processing box 1, and T-shaped sliders compatible with the T-shaped slide grooves are fixed at the bottom of the first rack 31 and the second rack 33, which improves the stability of the first rack 31 and the second rack 33. When the lifting block 26 rises, it can squeeze the first rack 31 to move the first rack 31. Since the first gear 32 is engaged with the first rack 31 and the second rack 33, the first rack 31 and the second rack 33 move in opposite directions. The movement of the second rack 33 can make the second arm 34 and the first rotating shaft 35 rotate along the axis of the first rotating shaft 35. When the lifting block 26 descends, the elastic force of the spring 36 can reset the first rotating shaft 35, thereby resetting the second arm 34, the second rack 33, the first gear 32 and the first rack 31.

[0023] The center of the first rotating shaft 35 is connected with a third arm 38, one side of the bottom of the third arm 38 is rotatably connected to the first connecting rod 39, and one end of the first connecting rod 39 is rotatably connected to the first bottom plate 312. It should be noted that the portion of the third arm 38 located below the first rotating shaft 35 is long enough, so that when the third arm 38 rotates along the axis of the first rotating shaft 35, the first bottom plate 312 can be completely separated from the range of the crushing chamber through the first connecting rod 39, so that the material on the first bottom plate 312 falls onto the first screen plate 6.

[0024] One side of the top of the third arm 38 is rotatably connected to the second connecting rod 310, and the top of the second connecting rod 310 is rotatably connected to the blocking block 311, which cooperates with the feed port 12, and the blocking block 311 is slidably connected to the limit frame 14 provided in the processing box 1. It should be noted that the length of the portion of the third arm 38 located below the first rotating shaft 35 is greater than the portion located above the first rotating shaft 35. When the third arm 38 rotates along the axis of the first rotating shaft 35, the blocking block 311 can block the opening at the bottom of the feed end 121 through the second connecting rod 310. When the first rotating shaft 35 is in the initial state, one end of the blocking block 311 is located in the feed port 12 and does not cooperate with the opening at the bottom of the feed end 121, thereby preventing the material from leaking from the feed port 12 to the outside, and also preventing the material from being unable to enter the crushing chamber through the feed port 12.

[0025] The fixed plate away from the first rotating shaft 35 is rotatably connected to the second rotating shaft 316, one end of the second rotating shaft 316 is connected to the fourth arm 315, one side of the top of the fourth arm 315 is rotatably connected to the third connecting rod 314, one end of the third connecting rod 314 is rotatably connected to the second bottom plate 313, the second bottom plate 313 and the first bottom plate 312 are slidably connected in the groove body set in the processing box 1, and the second bottom plate 313 and the first bottom plate 312 are provided with multiple leakage holes 318. It should be noted that: when the second bottom plate 313 and the first bottom plate 312 are fitted together, the screening chamber and the crushing chamber are separated. When the material is crushed, the material of the appropriate size can pass through the leakage hole 318. A rectangular hole compatible with the second bottom plate 313 and the first bottom plate 312 is provided inside the processing box 1. Support grooves are provided on both sides of the rectangular hole. The support grooves can support the two ends of the second bottom plate 313 and the first bottom plate 312, thereby improving the stability of the second bottom plate 313 and the first bottom plate 312. The length of the fourth arm 315 is long enough, so that when the fourth arm 315 rotates, the second bottom plate 313 can be completely separated from the range of the crushing chamber through the third connecting rod 314, so that the material on the second bottom plate 313 falls onto the first screen plate 6.

[0026] One end of the first rotating shaft 35 and the second rotating shaft 316 passes through the fixing plate and is connected to the fifth arm 37, and the bottom ends of the two fifth arm 37 are rotatably connected through the fourth connecting rod 317. It should be noted that the fourth connecting rod 317 can make the two fifth arm 37 rotate in the same direction, thereby making the first rotating shaft 35 and the second rotating shaft 316 rotate in the same direction.

[0027] In this embodiment, Figures 1 to 12 As shown, the extrusion crushing mechanism 4 is located on a side close to the second rotating shaft 316, and the extrusion crushing mechanism 4 includes two crushing wheels 41 rotatably connected to one side of the bottom of the processing box 1, and a gap is provided between the two crushing wheels 41. One end of the crushing wheel 41 is connected to a second gear 42, and the two second gears 42 are meshed and connected. Cams 43 are connected to both sides of the crushing wheel 41 close to the processing box 1, and the cams 43 cooperate with the first screen plate 6. It should be noted that: through the mutual meshing of the two second gears 42, the two crushing wheels 41 can be rotated in opposite directions to achieve the extrusion and crushing of the material, and the cam 43 can rotate with the crushing wheel 41. During the rotation, the first screen plate 6 can be repeatedly rotated to achieve a vibration effect, which can speed up the screening speed of the material.

[0028] In this embodiment, Figures 1 to 12 As shown, the magnetic attraction component 5 includes a magnetic attraction wheel 52 rotatably connected to one side of the processing box 1, the magnetic attraction wheel 52 is located above the crushing wheel 41 near the processing box 1, one end of the magnetic attraction wheel 52 is connected to the second motor 51, and the other end of the magnetic attraction wheel 52 is connected to the first synchronous wheel 53, the outer wall of the first synchronous wheel 53 is connected to a synchronous belt 54, the inner wall of the bottom of the synchronous belt 54 is connected to a second synchronous wheel 55, and the second synchronous wheel 55 is connected to one end of the crushing wheel 41 near the processing box 1. It should be noted that the magnetic attraction wheel 52 can absorb metal in the material, thereby achieving the effect of removing metal and allowing the metal to be reused, and the synchronous belt 54 can make the first synchronous wheel 53 and the second synchronous wheel 55 rotate synchronously, so that a crushing wheel 41 and the magnetic attraction wheel 52 rotate synchronously.

[0029] In this embodiment, Figures 1 to 12 As shown, one end of the first screen plate 6 passes through the discharge port provided in the processing box 1 and is located above the crushing wheel 41 and below the magnetic wheel 52. It should be noted that the first screen plate 6 will not collide with the magnetic wheel 52 when it rotates repeatedly.

[0030] A wedge block 13 is fixed to one side of the bottom of the screening chamber near the rotating end of the second screen plate 7. The wedge block 13 is located above the second screen plate 7. One end of the second screen plate 7 passes through the feed port set in the processing box 1 and is located below the crushing wheel 41. The holes of the second screen plate 7 and the first screen plate 6 are the same size as the holes of the leakage hole 318. It should be noted that: the second screen plate 7 will not collide with the crushing wheel 41 when it rotates repeatedly. There is a gap between the second screen plate 7 and the wedge block 13 when the second screen plate 7 rotates upward, which can squeeze the material that has not passed through the second screen plate 7 to achieve the third crushing. After the material crushed for the third time meets the requirements, it falls to the bottom of the screening chamber through the holes of the second screen plate 7. A discharge port is set on one side of the bottom of the processing box 1. The staff can take out the materials that meet the requirements through the discharge port. The hole of the discharge port is connected with a sealing block to prevent the material from floating out of the processing box 1 and affecting the environment.

[0031] In this embodiment, Figures 1 to 12 As shown, a first bevel 261 is provided on the top of the lifting block 26 near the first rack 31, and a second bevel 3101 matching the first bevel 261 is provided on the bottom of the first rack 31 near the lifting block 26. It should be noted that when the lifting block 26 squeezes the first rack 31, the first bevel 261 and the second bevel 3101 are in contact, which can facilitate the lifting block 26 to push the first rack 31.

[0032] In this embodiment, Figures 1 to 12 As shown, a blanking plate 9 is fixed to one side of the bottom of the processing box 1, and one side of the top of the blanking plate 9 is in contact with the outer side of the magnetic wheel 52. A baffle 91 is fixed to one side of the bottom of the blanking plate 9, and the baffle 91 is located above the crushing wheel 41 away from the processing box 1. It should be noted that when the magnetic wheel 52 rotates, the metal on its surface collides with the blanking plate 9, which can scrape the metal on the surface of the magnetic wheel 52 and make the metal fall onto the blanking plate 9. The baffle 91 can block the material and prevent the material from falling to the outside of the crushing wheel 41.

[0033] In this embodiment, Figures 1 to 12 As shown, a plurality of protrusions 271 are provided at the bottom of the crushing hammer 27. The protrusions 271 are truncated cone-shaped, and the diameter of the bottom of the protrusion 271 is smaller than the diameter of the top of the protrusion 271. It should be noted that the protrusions 271 can improve the crushing strength of the material when the crushing hammer 27 hits the material.

[0034] In this embodiment, Figures 1 to 12 As shown, the method for using the building material crushing device comprises the following steps: S1: First, the building material enters the feed port 12 through the feed end 121, and then enters the crushing chamber and falls on the second bottom plate 313 and the first bottom plate 312. After a small amount of material enters, the first motor 21 drives the first arm 22 to rotate, thereby driving the I-shaped slider 23 to slide, and then the slide rail 24 and the support seat 25 to descend, so that the crushing hammer 27 descends to hammer the material. During the descent of the crushing hammer 27, the roller 273 slides along the guide groove 11, so that the crushing hammer 27 can rotate, thereby improving the crushing strength of the material. The material that meets the requirements falls onto the first screen plate 6 through the leak hole 318. When the crushing hammer 27 rises to the top, it squeezes the first rack 3 through the lifting block 26. 1 moves the first rack 31, thereby rotating the first gear 32, and then moves the second rack 33, thereby rotating the second arm 34 and the first rotating shaft 35 along the axis of the first rotating shaft 35, and at the same time, the second rotating shaft 316 is rotated synchronously with the first rotating shaft 35 through the fifth arm 37 and the fourth connecting rod 317, and then the third arm 38 and the fourth arm 315 are rotated, so that the first connecting rod 39, the second connecting rod 310 and the third connecting rod 314 are rotated, so that the blocking block 311 seals the feed port 12, and at the same time, the first bottom plate 312 and the second bottom plate 313 move inversely to pull the first bottom plate 312 and the second bottom plate 313 out of the range of the crushing chamber, so that the first crushed material falls onto the first screen plate 6; S2: The magnetic wheel 52 and the first synchronous wheel 53 are driven to rotate by the second motor 51, so that the metal is adsorbed on the magnetic wheel 52, and the metal on the magnetic wheel 52 is dropped by the unloading plate 9, and the second synchronous wheel 55 and the first synchronous wheel 53 are driven to rotate synchronously by the synchronous belt 54, thereby driving a crushing wheel 41 and a cam 43 to rotate, so that the first screen plate 6 rotates repeatedly, and the material is screened quickly. The material passing through the first screen plate 6 finally falls to the bottom of the screening chamber. Since the two second gears 42 are meshed, the two crushing wheels 41 rotate at the same time, so that the second crushing of the material is realized, and the material after the second crushing falls onto the second screen plate 7; S3: While the first sieve plate 6 rotates repeatedly, the second sieve plate 7 is rotated synchronously through the synchronization rod 8, so as to facilitate the screening of the material. The material that has not passed through the second sieve plate 7 moves to the bottom of the wedge block 13. When the second sieve plate 7 rotates upward, it can cooperate with the wedge block 13 to squeeze the material, so that the material is crushed and passes through the second sieve plate 7 to fall to the bottom of the screening chamber.
