Description

Technical Field

[0001] The invention relates to a construction concrete crushing and separation device, which is used for recovering and separating sand and stone materials from waste concrete blocks in construction of building projects. Background Art

[0002] Concrete uses cement as a binder, sand and stone as aggregates, and water in a certain proportion and is prepared by mixing. It is widely used in construction projects. During the construction process of construction projects, excessive concrete is often used. The excess concrete cannot be used after it agglomerates. If it is directly discarded, it will cause environmental pollution and waste of materials.

[0003] Agglomerated concrete contains cement, sand and other agglomerates, as well as stones. These agglomerates can be used as backfill materials, and stones can be used to reconfigure concrete. To avoid waste of materials, the prior art generally uses a double-roll crusher to crush the agglomerated concrete, and then uses a vibrating screen to screen it.

[0004] The Chinese patent with patent publication number: CN116078462A discloses a high-efficiency crushing device for recycling waste concrete, which relates to the technical field of concrete recycling; it includes a crushing box, a crushing chamber is opened inside the crushing box along the height direction, and the inner wall of the crushing chamber is sequentially provided with a first crushing mechanism, a second crushing mechanism and a screening mechanism along the height direction, a feeding funnel is provided on the upper surface of the crushing box, the feeding funnel is communicated with the inner wall of the crushing chamber, the feeding funnel is located on the upper side of the first crushing mechanism, a discharging plate is provided on the inner wall of the crushing chamber and located on the lower side of the screening mechanism, and a discharging component is provided on the outer wall of the crushing box, and the discharging component is used to discharge the crushed waste concrete into the crushing box; it has the effect of improving the work efficiency of the staff.

[0005] The above patent has at least the following problems: First, the distance between the two crushing rollers of the roller crusher is relatively fixed. When crushing agglomerated concrete, due to the different sizes of stones in the concrete, when the distance between the crushing rollers is large, the crushing effect is not good. When the distance between the crushing rollers is small, excessive crushing will occur, resulting in stone crushing. Secondly, under the bonding effect of cement, some sand will adhere to the outside of the stone. It is difficult to fully separate the sand from the stone only by using a double-roll crusher, resulting in some sand still adhering to the processed stone, affecting subsequent use.

[0024] 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 technicians in this field without creative work are within the scope of protection of the present invention.

[0025] like Figure 1-16 As shown, the present invention has the following four specific embodiments. Example 1

[0026] The construction concrete crushing and separation device comprises a base 1, on which a collecting tank 11 is provided, a coarse crushing mechanism 2, a conveying mechanism 3 and an oscillating crushing mechanism 4, wherein the coarse crushing mechanism 2 is used for preliminarily crushing agglomerated concrete, the conveying mechanism 3 is used for conveying the preliminarily crushed concrete to the oscillating crushing mechanism 4, and the oscillating crushing mechanism 4 is used for oscillatingly crushing the preliminarily crushed concrete; The oscillation crushing mechanism 4 includes a separation cylinder 41, a rotating cylinder 42 and an oscillation box 43. The separation cylinder 41 is fixedly connected to the base 1 and is located directly above the collecting tank 11. A feed port 44 and a discharge port 45 are symmetrically provided on the upper and lower sides of the separation cylinder 41. The rotating cylinder 42 is rotatably connected in the separation cylinder 41. An oscillation cavity 46 is evenly provided on the inner circumference of the rotating cylinder 42. An opening 47 is provided on the outer wall of the rotating cylinder 42 corresponding to the position of the oscillation cavity 46. An oscillation box 43 is slidably connected in the oscillation cavity 46. The rotating cylinder 42 rotates intermittently at equal angles so that each oscillation box 43 is aligned with the feed port 44 in turn to receive the initially crushed concrete. The oscillation box 43 vibrates left and right to fully separate the sand and gravel in the concrete.

[0027] In this embodiment, Figure 2 As shown, the agglomerated concrete is preliminarily crushed by the coarse crushing mechanism 2 so that the concrete is broken into small pieces, and the conveying mechanism 3 conveys the small pieces of concrete to the oscillating crushing mechanism 4.

[0028] The oscillating crushing mechanism 4 includes a separation cylinder 41, a rotating cylinder 42 and an oscillation box 43. The rotating cylinder 42 rotates intermittently at equal angles. When the opening 47 is aligned with the feed port 44, the concrete enters the oscillation box 43, and the oscillation box 43 vibrates left and right, thereby shaking off the sand adhering to the stone. The device fully separates the sand and stone through the oscillation box 43 that vibrates left and right. Compared with the traditional double-roll crushing equipment, on the one hand, it will not cause the crushing of the stone, and on the other hand, it makes the surface of the stone smooth, thereby improving the effect of subsequent reuse. Example 2

[0029] The inner walls of the left and right side plates of the separation cylinder 41 are fixedly connected with an annular rotating seat 49, and the left and right ends of the rotating cylinder 42 are provided with an annular mounting groove 410, and the inner wall of the mounting groove 410 is rotatably connected to the rotating seat 49. The center of the separation cylinder 41 is rotatably connected with a driving shaft 411, and a pair of disks 412 are fixedly connected to the driving shaft 411. The disks 412 are fixedly connected to the inner wall of the rotating cylinder 42 through supporting plates 413 evenly arranged around the circumference. A pair of vertical frames 414 are fixedly connected to the left side of the separation cylinder 41, and the driving shaft 411 is rotatably connected to the vertical frame 414 on the right side. A groove wheel 415 is fixedly connected to the left end of the driving shaft 411, and the groove wheel 415 Radial grooves 416 and locking grooves 417 are evenly arranged on the upper circumference, and the number of radial grooves 416 and locking grooves 417 is consistent with that of the oscillation box 43. A power shaft 418 is rotatably connected to the stand 414 on the left side, and an arc gear 419 is fixedly connected to the right end of the power shaft 418. A lock disk 420 is fixedly connected to the right side of the arc gear 419, and an avoidance opening 421 is arranged on the lock disk 420. A pin 422 is fixedly connected to the arc gear 419. A distribution box 423 is fixedly connected to the base 1, and a servo motor 424 is fixedly connected to the distribution box 423. The output of the servo motor 424 is connected to the power shaft 418 through a coupling.

[0030] Furthermore, a round roller 426 is rotatably connected between the two left and right supporting plates 413 through a rotating shaft 425, a rolling gear 427 is fixedly connected to the head of the rotating shaft 425, a gear ring 428 is fixedly connected to the inner ring of the rotating seat 49, the rolling gear 427 is meshed with the gear ring 428, two spiral grooves 429 with opposite rotation directions are provided on the round roller 426, the heads of the two spiral grooves 429 are connected through a transverse groove 430, a track groove 431 is provided at the bottom of the oscillation chamber 46, a track rod 432 is fixedly connected in the track groove 431, a track block 433 is fixedly connected to the side of the oscillation box 43 close to the center of the rotating drum 42, the track block 433 is slidably connected to the track rod 432, a spring 434 is sleeved on the track rod 432 on the left side of the track block 433, a push rod 435 is fixedly connected to the side of the track block 433 away from the oscillation box 43, and the head of the push rod 435 is slidably connected in the spiral groove 429 and the transverse groove 430.

[0031] Furthermore, when the push rod 435 is located at the right end of the transverse groove 430 , the spring 434 is in a compressed state.

[0032] Furthermore, a hanging plate 436 is evenly fixed in the opening 47 in the transverse direction, and a hanging rod 437 is evenly fixed on the inner wall circumference of the hanging plate 436 .

[0033] In this embodiment, the driving structure of the drum 42 and the oscillation box 43 is disclosed, such as Figure 1 as well as Figure 3As shown, when the servo motor 424 is working, it drives the power shaft 418 to rotate, and the power shaft 418 drives the arc gear 419, the lock plate 420 and the pin 422 to rotate. When the pin 422 enters the radial groove 416, the groove wheel 415 rotates. When the pin 422 disengages from the radial groove 416, the groove wheel 415 remains stationary, and the groove wheel 415 drives the drive shaft 411 to rotate, so that the rotating drum 42 rotates. Since the number of radial grooves 416 and the vibration box 43 is the same, the angle of each rotation of the groove wheel 415 is equal to the angle between two adjacent vibration boxes 43, that is, the intermittent rotation of the rotating drum 42 and the vibration box 43 is realized. When the position of the vibration box 43 and the opening 47 is aligned with the feed port 44, the concrete enters the vibration box 43.

[0034] like Figure 8-10 As shown, when the drum 42 rotates, it drives the rolling gear 427 to revolve around the axis of the driving shaft 411. Under the action of the gear ring 428, the rolling gear 427 rotates, thereby driving the round roller 426 to rotate. Assuming that in the initial position, under the action of the spring 434, the push rod 435 is located at the right end of the transverse groove 430. Looking from right to left, when the round roller 426 rotates counterclockwise, the driving push rod 435 moves to the left in the spiral groove 429, so that the track block 433 and the shock box 43 move to the left, and the spring 434 is further compressed. When the push rod 435 moves to the left end of the spiral groove 429, under the action of the spring 434, the push rod 435 quickly impacts to the right in the transverse groove 430, thereby realizing the leftward movement and rapid rightward movement of the shock box 43, and realizing the left and right reciprocating vibration of the shock box 43.

[0035] Since the suspension rod 437 is provided and the position of the suspension rod 437 relative to the rotating drum 42 is fixed, when the vibration box 43 vibrates, the concrete blocks inside it will continuously move and collide with the suspension rod 437, so that the sand material adhered to the stone can be shaken off and crushed. Example 3

[0036] An annular cavity 51 is provided inside the separation cylinder 41, an arc-shaped groove body 52 is provided at the lower part of the separation cylinder 41, a cylinder 53 is rotatably connected in the annular cavity 51, a first screen 54 is fixedly connected to the bottom of the cylinder 53, a loading port 55 is provided above the cylinder 53 opposite to the first screen 54, a discharge port 56 is provided on the front side of the cylinder 53, a positioning screw 57 is fixedly connected to the cylinder 53, and a slide groove 58 communicated with the annular cavity 51 is provided on the separation cylinder 41, the positioning screw 57 extends through the slide groove 58, and a positioning nut 59 is meshed on the positioning screw 57.

[0037] Furthermore, an isolation seat 12 is fixedly connected to the middle of the collecting trough 11, and the top of the isolation seat 12 is tilted downward in the direction from the back to the front. The isolation seat 12 separates the collecting trough 11 into a sand trough 1101 on the front side and a stone trough 1102 on the rear side. A first positioning plate 510 is fixedly connected to the cylinder 53 on the rear side of the first screen 54, and a sliding plate 511 is fixedly connected to the front side of the first positioning plate 510. A second positioning plate 512 is fixedly connected to the cylinder 53 above the discharge port 56, and a second screen 513 is fixedly connected to the lower part of the second positioning plate 512.

[0038] In this embodiment, this embodiment discloses a structure for screening concrete processed by the oscillating crushing mechanism 4, such as Figure 4-6 As shown, the cylinder 53 is rotatably connected in the annular cavity 51 , and the slot 52 is provided to facilitate the installation and movement of the first positioning plate 510 and the second positioning plate 512 .

[0039] like Figure 7 As shown, during the operation of the device, first, the first screen 54 is aligned with the discharge port 45, and the first positioning plate 510 is in contact with the rear side of the isolation seat 12. At this time, the loading port 55 is aligned with the feeding port 44, and small pieces of concrete enter the separation cylinder 41 through the feeding port 44 and the loading port 55. The intermittent equal-angle rotation of the rotating cylinder 42 allows the concrete to enter each vibration box 43 in turn. The left and right vibration of the vibration box 43 separates the sand from the gravel. When the vibration box 43 moves to the bottom, the sand that meets the size requirements is screened out through the first screen 54, and the screened sand enters the sand trough 1101 through the sliding plate 511, and the remaining material continues to vibrate.

[0040] like Figure 7 As shown, when there are more stones in the vibration box 43, the cylinder 53 can be rotated counterclockwise by a certain angle so that the first screen 54 is staggered from the discharge port 45, and the discharge port 56 is also staggered from the discharge port 45. At this time, the feed port 44 and the discharge port 45 are closed, and no concrete enters the separation cylinder 41. The rotating cylinder 42 continues to rotate, and the vibration mechanism drives the vibration box 43 to vibrate left and right to completely separate the sand and stones.

[0041] Then rotate the cylinder 53 counterclockwise again so that the second positioning plate 512 contacts the front side of the isolation seat 12. At this time, the discharge port 56 and the outlet port 45 are aligned, and the feed port 44 is closed by the cylinder 53. The material is discharged through the outlet port 45 and the discharge port 56, and is further screened by the second screen 513, so that the sand falls to the top of the isolation seat 12 and slides into the sand trough 1101 from the top of the isolation seat 12, while the stone slides into the stone trough 1102 on the second screen 513.

[0042] Then, the cylinder 53 is rotated clockwise to make the first positioning plate 510 contact the rear side of the isolation seat 12 .

[0043] When the cylinder 53 rotates, the positioning nut 59 is loosened. When the cylinder 53 reaches a desired position, the positioning nut 59 is tightened to fix the position of the cylinder 53. Example 4

[0047] The position of the teeth on the arc gear 419 corresponds to the position of the push pin 422. When the push pin 422 disengages from the radial groove 416, the transmission gear 38 rotates, and then the transmission shaft 37 rotates. Under the action of the first pulley 29 and the first belt 210, the conveying shaft 32 and the conveying blade 36 rotate, that is, the conveying blade 36 and the rotating drum 42 rotate alternately. When the rotating drum 42 is braked, the conveying blade 36 rotates.

[0048] The concrete in the hopper 23 enters the conveying cylinder 31 through the drop pipe 34, and is transported from left to right by the rotating conveying blades 36, and enters the temporary storage box 33 through the feeding pipe 35. When the opening 47 is aligned with the feed port 44, the concrete can enter the vibration box 43. When the cylinder 53 closes the feed port 44, the concrete can be stored in the temporary storage box 33.

[0049] It should be noted that the present invention has certain requirements for the rotation direction of the crushing roller 22, the conveying blade 36 and the round roller 426. When viewed from right to left, the rotation direction of the servo motor 424 is set so that the power shaft 418 rotates counterclockwise. At this time: The pulverizing roller 22 rotates counterclockwise.

[0050] The power shaft 418 drives the transmission gear 38 to rotate through the arc gear 419. The outer meshing arc gear 419 rotates in the opposite direction to the transmission gear 38, that is, the transmission gear 38 rotates clockwise, and then the conveying blade 36 rotates clockwise. Figure 3 As shown, when the conveying blade 36 rotates clockwise, the material is conveyed from left to right.

[0051] The power shaft 418 drives the transmission gear 38 to rotate through the arc gear 419. The outer meshing arc gear 419 rotates in the opposite direction to the transmission gear 38, that is, the transmission gear 38 rotates clockwise, and then the conveying blade 36 rotates clockwise. Figure 3 As shown, when the conveying blade 36 rotates clockwise, the material is conveyed from left to right.

[0052] The working principle of the present invention is as follows: When the device is working, the servo motor 424 is powered by the distribution box 423. First, the first screen 54 is aligned with the discharge port 45, the positioning nut 59 is tightened to fix the cylinder 53, and the servo motor 424 is started. The agglomerated concrete is put into the crushing box 21. When the crushing rod 28 rotates, the concrete is crushed into small pieces and enters the conveying cylinder 31 through the hopper 23 and the drop pipe 34.

[0053] The conveying blade 36 conveys the concrete from the left to the rear when it rotates.

[0054] The drum 42 rotates intermittently. When the drum 42 brakes, the topmost vibration box 43 is aligned with the feed port 44. At this time, the conveying blades 36 work, and the concrete enters the vibration box 43. When the drum 42 rotates, the conveying blades 36 brake. During the rotation of the drum 42, the round roller 426 rotates to realize the left and right vibration of the vibration box 43 to separate the sand and the gravel. When the vibration box 43 moves to the bottom, it is screened through the first screen 54, and the sand enters the sand trough 1101 through the sliding plate 511, and the remaining material continues to be vibrated and crushed.

[0055] When there is a lot of residual material in the vibration box 43, the cylinder 53 is rotated to close the feed port 44 and the discharge port 45. At this time, the concrete transported by the conveying cylinder 31 can be retained in the temporary storage box 33, and the residual material in the vibration box 43 continues to vibrate for a period of time. Then the cylinder 53 is rotated again to make the second positioning plate 512 contact the front side of the isolation seat 12, and the sand and gravel are transported to the sand trough 1101 and the stone trough 1102 respectively through the second screen 513.

[0056] After a period of time, the cylinder 53 is rotated in the opposite direction so that the first screen 54 is aligned with the discharge port 45 .
