Description

Technical Field

[0001] The present application relates to the technical field of construction waste processing, and in particular to a jaw crusher for processing construction waste. Background Art

[0002] Jaw crusher is abbreviated as jaw crusher, which mainly includes a fixed jaw plate for crushing and a movable jaw plate for swinging and squeezing crushing. The movable jaw plate periodically swings toward the fixed jaw plate to crush the material. The crushed material is discharged when the movable jaw plate swings away from the fixed jaw plate in the opposite direction, creating a large gap and relying on the material's own weight to move downward. Each periodic swinging movement of the movable jaw crushes the material once and discharges it downward for a distance. The material is finally discharged from the discharge port at the lower end of the two jaw plates. However, when the fixed jaw plate and the movable jaw plate crush the construction waste, some of the crushed construction waste may be stuck in the crushing grooves on the fixed jaw plate and the movable jaw plate, affecting the crushing effect of subsequent materials and requiring manual cleaning.

[0003] In the existing jaw crusher, such as the Chinese patent with announcement number CN205925802U, a jaw crusher is disclosed, which specifically includes a frame, a left and a right bearing seat on each side of the frame, an eccentric shaft passing through the left and right bearing seats and the frame, and a movable jaw is connected to the eccentric shaft. The lower part of the frame is connected to an adjustment seat and a pull rod, and the top rod and the pull rod on the adjustment seat are respectively connected to the lower end of the movable jaw, and the other side of the frame is connected to a static jaw; the movable jaw and the static jaw are respectively connected to a movable tooth plate and a fixed tooth plate, and the movable tooth plate and the fixed tooth plate both have convex long teeth, and the convex long tooth tips have concave and convex hard alloy transverse teeth.

[0004] In the above-mentioned existing technology, the function of crushing construction waste can also be achieved, but on the first hand, when the above-mentioned existing technology crushes the material, the construction waste in the crushing grooves on the surface of the fixed jaw plate and the movable jaw plate cannot be cleaned, resulting in clogging of the grooves, affecting the subsequent crushing effect of subsequent construction waste; on the second hand, when the above-mentioned existing technology crushes the material, the soil and fine particles in the construction waste may adhere to the grooves on the surface of the fixed jaw plate and the movable jaw plate, resulting in the grooves being easily clogged and affecting the crushing effect of the material; based on this, there is still room for improvement on the technology of the existing jaw processing crusher.

[0031] The embodiment of the present application discloses a jaw crusher for processing construction waste, which can accurately crush construction waste and clean impurities.

[0032] Reference Figure 3As shown, the present embodiment discloses a jaw crusher for processing construction waste, comprising: a shell 1, which is a hollow rectangular structure, a feed rack is installed on the upper left end of the shell 1, and the cross-section of the feed rack is triangular; a fixed jaw plate 2, which is installed on the left side of the inside of the shell 1, and a fixed cavity is provided between the fixed jaw plate 2 and the shell 1; a driving module 3, which is installed on the shell 1, and an inclined groove is provided on the left side of the driving module 3; a movable jaw plate 4, which is installed in the inclined groove of the driving module 3, and a movable cavity is provided between the movable jaw plate 4 and the driving module 3, and crushing grooves are evenly provided on the inner sides of the fixed jaw plate 2 and the movable jaw plate 4; a cleaning module 5, which is respectively installed in the fixed cavity and the movable cavity, and the cleaning module 5 cooperates with the fixed jaw plate 2 and the movable jaw plate 4 respectively to clean Module 5 is used to clean the gravel stuck in the crushing grooves on the inner sides of the fixed jaw plate 2 and the movable jaw plate 4; the extrusion module 6 is arranged on the right side of the interior of the shell 1, and the extrusion module 6 cooperates with the cleaning module 5 on the movable jaw plate 4. The extrusion module 6 is used to drive the cleaning module 5 to clean the inside of the crushing groove on the movable jaw plate 4; the connecting module 7 is symmetrically installed on the inner wall of the shell 1, the left end of the connecting module 7 is connected to the cleaning module 5 on the left side of the shell 1, and the right end of the connecting module 7 is connected to the driving module 3. The connecting module 7 is used to drive the cleaning module 5 to clean the inside of the crushing groove on the fixed jaw plate 2; the support module 8 is arranged at the lower end of the right side of the interior of the shell 1, and the support module 8 is used to support the lower end of the driving module 3.

[0033] During actual use, when the construction waste is crushed, the construction waste enters from the feed rack, and the driving module 3 drives the movable jaw plate 4 to swing periodically toward the fixed jaw plate 2 to crush the construction waste. The crushed construction waste is discharged downward when the movable jaw plate 4 swings away from the fixed jaw plate 2. The construction waste moves downward under its own weight. Each periodic swing of the movable jaw plate 4 crushes the construction waste once and discharges it downward for a distance. The construction waste is finally discharged from the lower ends of the fixed jaw plate 2 and the movable jaw plate 4; when the driving module 3 drives the movable jaw plate 4 to swing away from the fixed jaw plate 2, the cleaning module 5 located on the right side of the shell 1 is pressed against the extrusion module 6 Under the action of the movable jaw plate 4, the cleaning module 5 located on the left side of the shell 1 extends into the crushing groove on the fixed jaw plate 2 under the action of the connecting module 7. The extended cleaning module 5 cleans the construction waste and impurities stuck in the crushing groove, thereby improving the crushing efficiency; when the driving module 3 drives the movable jaw plate 4 to swing toward the fixed jaw plate 2, the movable jaw plate 4 and the fixed jaw plate 2 crush the construction waste, and the supporting module 8 supports the lower end of the driving module 3. The movable jaw plate 4 and the fixed jaw plate 2 on the driving module 3 are arranged in a V shape, so that the mineral is gradually crushed into the required size by the passive jaw plate 4 and the fixed jaw plate 2.

[0034] Reference Figure 5As shown, the driving module 3 includes an eccentric shaft 31, a movable jaw frame 32, a flywheel 33, a pulley 34, a driving motor 35 and a belt 36. The eccentric shaft 31 is installed on the upper right end of the shell 1 through a bearing, the movable jaw frame 32 is installed in the middle of the eccentric shaft 31, and an inclined groove is provided on the left side of the movable jaw frame 32. Flywheels 33 are symmetrically installed at both ends of the eccentric shaft 31, and a pulley 34 is installed on the flywheel 33 on the front side. The driving motor 35 is installed on the right side of the shell 1 through the motor seat, and a belt 36 is installed between the output shaft of the drive motor 35 and the belt pulley 33.

[0035] During actual use, when construction waste is crushed, the driving motor 35 drives the pulley 34 to rotate at a constant speed through the belt 36, and the eccentric shaft 31 rotates synchronously with the pulley 34 through the flywheel 33, so that the movable jaw frame 32 swings back and forth under the action of the eccentric shaft 31, and the movable jaw plate 4 swings synchronously with the movable jaw frame 32, thereby achieving the effect of crushing the construction waste.

[0036] It should be noted that the flywheel plays the role of energy storage and inertia. The flywheel forms inertial force through rotation, which can obtain sufficient kinetic energy and achieve efficient crushing of construction waste.

[0037] Reference Figure 6 As shown, the cleaning module 5 includes a cleaning frame 51, a dredging plate 52, a connecting plate 53, a cleaning unit 54 and a sealing ring 55. A rectangular groove is provided on the inner side of the crushing groove on the fixed jaw plate 2 and the movable jaw plate 4. The cleaning frame 51 is slidably provided in the rectangular groove. The dredging plate 52 is installed on the outer side of the cleaning frame 51. The dredging plate 52 is a wear-resistant steel plate. Crushing protrusions are evenly provided on the outer surface of the dredging plate 52. Connecting plates 53 are installed between the inner sides of the cleaning frames 51. Mounting grooves are evenly provided between the connecting plates 53 and the cleaning frames 51. The cleaning unit 54 is installed in the mounting groove. Sealing rings 55 are provided on the outer sides of the fixed cavity and the movable cavity. The sealing rings 55 are made of flexible and retractable material.

[0038] During actual use, when the movable jaw plate 4 swings away from the fixed jaw plate 2, the connecting plate 53 located on the left side of the shell 1 drives the cleaning frame 51 to extend into the crushing groove on the movable jaw plate 4 under the action of the connecting module 7, and the connecting plate 53 located on the right side of the shell 1 extends into the crushing groove on the fixed jaw plate 2 under the action of the extrusion module 6. The dredging plate 52 outside the cleaning frame 51 can push out the gravel in the crushing groove, and the cleaning unit 54 cleans the impurities in the crushing groove, thereby realizing the function of cleaning the crushed construction waste and impurities in the crushing grooves on the fixed jaw plate 2 and the movable jaw plate 4, which is beneficial to improving the crushing effect of subsequent construction waste.

[0039] It should be noted that when there is a lot of sticky substance remaining on the surface of the construction waste, the crushed construction waste is not easy to fall off, and the sticky substance is easy to accumulate in the crushing groove. The sealing ring 55 can be connected to the water inlet pipe, and the cleaning unit 54 can facilitate the water in the sealing ring 55 to clean the crushing groove, thereby ensuring the crushing effect of the fixed jaw 2 and the movable jaw 4.

[0040] Reference Figure 7 As shown, the cleaning unit 54 includes a rectangular frame 541, a sleeve 542, a piston rod 543, a sealing plug 544 and a control component 545. The rectangular frame 541 is installed in the installation groove, a cylindrical groove is provided in the middle of the rectangular frame 541, a sleeve 542 is installed in the cylindrical groove, a piston rod 543 is slidingly provided in the middle of the sleeve 542, a sealing plug 544 is installed on the outside of the sleeve 542, and a control component 545 is installed on the sealing plug 544. The end of the piston rod 543 located on the left side of the shell 1 is connected to the inner wall of the shell 1, and the end of the piston rod 543 located on the right side of the shell 1 is connected to the driving module 3. A circulation groove is provided in the rectangular frame 541, and the circulation groove is connected to the outside of the sleeve 542. Inclined grooves are evenly provided on the rectangular frame 541, and the inclined grooves are connected to the circulation grooves.

[0041] During actual use, when the cleaning frame 51 extends into the crushing groove, the sleeve 542 moves synchronously with the cleaning frame 51. Since the piston rod 543 is fixed, the pressure between the sealing plug 544 and the piston rod 543 increases, and the control component 545 is closed. At this time, the piston rod 543 squeezes the water on the outside of the sleeve 542 into the circulation groove. The water is sprayed out from the inclined groove through the circulation groove to clean the sticky substance in the crushing groove, preventing the crushing groove from being blocked, and improving the crushing efficiency of construction waste.

[0042] When the cleaning frame 51 is reset from the crushing groove, the sleeve 542 moves synchronously with the cleaning frame 51. Since the piston rod 543 is fixed, the pressure between the sealing plug 544 and the piston rod 543 is reduced, the control component 545 is opened, and the water in the sealing ring 55 enters the sleeve 542, making it easier to clean the crushing groove next time.

[0043] Reference Figure 7 As shown, the control assembly 545 includes a tapered piston 5451, a T-shaped rod 5452 and a telescopic spring 5453. The sealing plug 544 is provided with a T-shaped slot, the inner side of the T-shaped slot is provided with a tapered piston 5451, the outer side of the tapered piston 5451 is installed with a T-shaped rod 5452, and the telescopic spring 5453 is installed on the T-shaped rod 5452.

[0044] During actual use, when the cleaning frame 51 is reset from the crushing groove, the sleeve 542 moves synchronously with the cleaning frame 51. Since the piston rod 543 is fixed, the pressure between the sealing plug 544 and the piston rod 543 is reduced, and the tapered piston 5451 drives the T-shaped rod 5452 to move toward the inside of the sleeve 542. The telescopic spring 5453 is in a compressed state. At this time, the T-shaped slot is opened, and the water in the sealing ring 55 enters the inside of the sleeve 542, realizing the function of automatically controlling the one-way flow of water, which is convenient for subsequent flushing of the crushing groove.

[0045] When the cleaning frame 51 extends into the crushing groove, the sleeve 542 moves synchronously with the cleaning frame 51. Since the piston rod 543 is fixed, the pressure between the sealing plug 544 and the piston rod 543 increases. At the same time, under the action of the telescopic spring 5453, the T-shaped rod 5452 drives the conical piston 5451 to reset, the T-shaped groove is closed, and the piston rod 543 squeezes the water outside the sleeve 542 into the circulation groove.

[0046] It should be noted that a flexible sealing ring is provided on the outside of the inclined groove on the rectangular frame 541. When the flexible sealing ring is located in the rectangular groove, the inclined groove is closed. When the flexible sealing ring is located in the groove, the inclined groove is opened to facilitate water to enter the interior of the sleeve 542.

[0047] Reference Figure 4 As shown, the extrusion module 6 includes a connecting column 61, a return spring 62 and an extrusion roller 63. The movable jaw plate 4 is evenly provided with a card slot, and a connecting column 61 is provided in the card slot. The connecting column 61 is connected to the cleaning module 5 on the movable jaw plate 4. A return spring 62 is installed on the connecting column 61. A squeezing roller 63 is installed inside the outer shell 1, and the squeezing roller 63 cooperates with the cleaning module 5.

[0048] During actual use, when the movable jaw plate 4 swings away from the fixed jaw plate 2, the squeezing roller 63 serves to limit the cleaning module 5, so that the cleaning module 5 extends into the rectangular groove on the movable jaw plate 4. At this time, the reset spring 62 is gradually compressed; when the movable jaw plate 4 approaches the side of the fixed jaw plate 2, the cleaning module 5 is reset under the action of the reset spring 62.

[0049] Reference Figure 8 As shown, the connecting module 7 includes a mounting bracket 71, a connecting rod 72, a connecting bracket 73 and a limit block 74. A through groove is provided on the inner wall of the shell 1, and the mounting bracket 71 is installed in the through groove. A connecting rod 72 is slidingly provided in the middle of the mounting bracket 71, and an empty groove is provided on the right side of the mounting bracket 71. The connecting bracket 73 is symmetrically installed on the end of the movable jaw plate 4, the connecting bracket 73 is located in the empty groove, and a movable groove is provided in the middle of the connecting bracket 73. The end of the connecting rod 72 passes through the movable groove, and limiting blocks 74 are respectively installed on the connecting rods 72 located at both ends of the connecting bracket 73.

[0050] When the movable jaw plate 4 is swung toward the side close to the fixed jaw plate 2, the movable jaw frame 32 drives the connecting frame 73 to move to the right, and the connecting rod 72 moves synchronously with the connecting frame 73 under the action of the limit block 74 located on the right side of the connecting frame 73, and the connecting rod 72 pulls the cleaning module 5 on the left side of the shell 1 to extend from the crushing groove on the fixed jaw plate 2; when the movable jaw plate 4 is swung toward the side close to the fixed jaw plate 2, the movable jaw frame 32 drives the connecting frame 73 to move to the left, and the connecting rod 72 moves synchronously with the connecting frame 73 under the action of the limit block 74 located on the left side of the connecting frame 73, and the connecting rod 72 pushes the cleaning module 5 on the left side of the shell 1 to reset from the crushing groove on the fixed jaw plate 2.

[0051] Reference Figure 4 As shown, the support module 8 includes a support seat 81, a toggle plate 82, a pull rod 83, a limiting ring 84 and a tension spring 85. The support seat 81 is installed at the lower end of the right inner wall of the shell 1, and the toggle plate 82 is installed at the upper end of the support seat 81. The end of the toggle plate 82 is connected to the driving module 3. The lower end of the support seat 81 is symmetrically provided with a slide groove, and a pull rod 83 is installed in the slide groove. One end of the pull rod 83 is connected to the driving module 3, and a limiting ring 84 is installed at the other end of the pull rod 83. A tension spring 85 is installed on the pull rod 83 located between the support seat 81 and the limiting ring 84.

[0052] During actual use, the elbow plate 82 can support the movable jaw frame 32 and make the movable jaw plate 4 and the fixed jaw plate 2 form a V-shaped structure, which is conducive to the movable jaw plate 4 and the fixed jaw plate 2 gradually crushing the construction waste into the required size.

[0053] The implementation principle of this embodiment is:

[0054] 1: Gradual crushing, the driving motor 35 drives the pulley 34 to rotate at a constant speed through the belt 36, and the eccentric shaft 31 rotates synchronously with the pulley 34 through the flywheel 33, so that the movable jaw frame 32 swings back and forth under the action of the eccentric shaft 31, and the movable jaw plate 4 swings synchronously with the movable jaw frame 32, achieving the effect of crushing the construction waste.

[0055] 2: Extend for cleaning. When the cleaning frame 51 extends into the crushing groove, the sleeve 542 moves synchronously with the cleaning frame 51. Since the piston rod 543 is fixed, the pressure between the sealing plug 544 and the piston rod 543 increases, and the control component 545 is closed. At this time, the piston rod 543 squeezes the water on the outside of the sleeve 542 into the circulation groove. The water is sprayed out from the inclined groove through the circulation groove to clean the impurities in the crushing groove.

[0056] 3: Reset feeding. When the cleaning frame 51 is reset from the crushing groove, the sleeve 542 moves synchronously with the cleaning frame 51. Since the piston rod 543 is fixed, the pressure between the sealing plug 544 and the piston rod 543 is reduced, and the tapered piston 5451 drives the T-shaped rod 5452 to move inside the sleeve 542. The telescopic spring 5453 is in a compressed state. At this time, the T-shaped slot opens, and the water in the sealing ring 55 enters the interior of the sleeve 542.

[0057] The embodiments of this specific implementation method are all preferred embodiments of the present invention and are not intended to limit the scope of protection of the present invention. Therefore, any equivalent changes made based on the structure, shape, and principle of the present invention should be included in the scope of protection of the present invention.
