Description

Technical Field

[0001] The invention relates to the technical field of construction waste crushing, and in particular to an energy-saving waste recycling and crushing device for environmental engineering. Background Art

[0002] During the construction process, a large amount of construction waste will be generated. If these construction wastes are simply piled up, it will not only cause a waste of resources, but also affect the environment. In order to ensure the full utilization of resources and reduce the impact on the environment, the existing treatment of construction waste can be carried out by using a hammer crusher to use the rotational force and centrifugal force to crush the construction waste into powder, which is convenient for subsequent recycling.

[0003] When using a hammer crusher to crush construction waste, if too much large pieces of construction waste are added at a time, the hammer head will encounter too much resistance during rotation, which will increase the power consumption of the hammer crusher and cause it to take a long time to crush and have low crushing efficiency.

DETAILED DESCRIPTION

[0018] In order to make the objectives, technical solutions and advantages of the present invention more clear, the present invention will be further described in detail below with reference to the accompanying drawings.

[0019] In order to avoid excessive large pieces of construction waste blocking the normal operation of the hammer, an energy-saving waste recycling and crushing device for environmental engineering is proposed. By intercepting, the amount of large pieces of construction waste in contact with the hammer is controlled to ensure the normal operation of the hammer. The specific plan is as follows: Combination Figure 1-Figure 3 As shown, it includes: a crusher body 1, the crusher body 1 has a frame 101, a power unit 102 and a crushing unit 103; a support frame 2, which has at least two, and a first hydraulic rod 3 is fixedly connected to the upper part of the support frame 2; a bracket 4, which is slidably connected to the upper part of the frame 101 and is used to lift waste materials. The part of the bracket 4 in the frame 101 is arched to improve its compression resistance. The bracket 4 is fixedly connected to the telescopic ends of all the first hydraulic rods 3. The number of support frames 2 is used to ensure the stability of the moving process of the bracket 4. The bracket 4 is provided with a through groove for unloading; an oil injection assembly, which is arranged on the frame 101 and is used to simultaneously control the extension length of all the first hydraulic rods 3.

[0020] In the above scheme, it is intended to prevent the problem of too many large pieces of construction waste from jamming the hammer head and causing low crushing efficiency or even damage to the crusher, thereby improving work efficiency and reducing energy loss. In this embodiment, the crusher body 1 is not limited to the three parts of the frame 101, the power unit 102 and the crushing unit 103. Except for the power shaft of the crushing unit 103, the others are existing structures (no more description will be given). The support frame 2 has at least two, which are located on both sides of the frame 101 and are symmetrically distributed to ensure the stability of the bracket 4. The number of the first hydraulic rods 3 on the support frame 2 is not limited to one, and it is sufficient to ensure the stability of the up and down movement of the bracket 4 (that is, if the support frame 2 has only one first hydraulic rod 3, the first hydraulic rod 3 is in the middle of the support frame 2, and if the support frame 2 has multiple first hydraulic rods 3, the first hydraulic rods 3 are equidistantly arranged on the support frame 2). The bracket 4 can be made of a wear-resistant and tough material such as high manganese steel to ensure its service life. The bracket 4 is provided with evenly distributed through grooves so that the initially crushed construction waste falls evenly to the lower side of the bracket 4. When the telescopic ends of all the first hydraulic rods 3 move together, the bracket 4 is driven to move synchronously, changing the relative position between the bracket 4 and the crushing part 103. An elastic shielding net (not shown in the figure) is provided between the bracket 4 and the frame 101 to prevent the discharge of construction materials.

[0021] Combination Figure 1 and Figure 3-Figure 5 As shown, the oil injection assembly includes: a first mounting frame 5, which is fixedly connected to the frame 101, the first mounting frame 5 is spline-connected with a threaded barrel 6, the threaded barrel 6 is fixedly connected with an extrusion plate 7, and a cylinder 8 is installed on the side of the frame 101 close to the first mounting frame 5 through a fixed frame. The cylinder 8 is used to inject hydraulic oil into the first hydraulic rod 3, and the telescopic end of the cylinder 8 is fixedly connected to the extrusion plate 7; a threaded sleeve 9, which is rotatably connected to the first mounting frame 5, the threaded sleeve 9 is threadedly connected to the threaded barrel 6, and is used to drive the threaded barrel 6 to slide along the first mounting frame 5. The frame 101 is installed with a transmission 10 through a fixed frame, and a transmission member is arranged between the output shaft of the transmission 10 and the threaded sleeve 9, and the transmission 10 is used to control the reciprocating rotation of the threaded sleeve 9; a power transmission assembly is arranged on the frame 101, and is used to drive the input shaft of the transmission 10 to rotate.

[0022] In the above scheme, the purpose is to control the amount of hydraulic oil in the fixed part of all the first hydraulic rods 3 and change the position of the bracket 4. The first mounting frame 5 is composed of a U-shaped frame, an L-shaped frame and a spline rod, wherein the threaded barrel 6 is spline-connected to the spline rod. There are at least two cylinders 8, and the number of the first hydraulic rods 3 is an integer multiple of the number of cylinders 8, which are used to synchronously control the movement of the telescopic parts of all the first hydraulic rods 3. When the threaded barrel 6 moves, the position of the extrusion plate 7 is controlled to change the position of the telescopic end of the cylinder 8, and then the amount of hydraulic oil in the first hydraulic rod 3 is controlled through the pipeline. The threaded sleeve 9 is located at the U-shaped frame, and the threaded barrel 6 is driven to move by the rotation of the threaded sleeve 9. The transmission 10 is used to change the unidirectional rotational force into a bidirectional reciprocating rotational force, so that the threaded sleeve 9 drives the threaded barrel 6 to reciprocate horizontally.

[0023] Combination Figure 1 and Figure 6-Figure 8 As shown, the power transmission component includes: a reducer 11, which is installed on the frame 101 through a mounting plate, a transmission member is arranged between the input shaft of the reducer 11 and the power unit 102, and a transmission sleeve 12 is installed on the output shaft of the reducer 11, the reducer 11 is used to reduce the rotation speed transmitted to the transmission sleeve 12 and increase the torque of the transmission sleeve 12, and a blind hole 1201 is arranged in the transmission sleeve 12, and the blind hole 1201 has a spline groove 1202; a second mounting frame 13, which is fixed to the frame 101 through a mounting plate, the second mounting frame 13 is rotatably connected with a first spline sleeve 1301, the first spline sleeve 1301 is spline-connected with a second spline sleeve 14, the second spline sleeve 14 is slidably matched with the blind hole 1201, and the second spline sleeve 14 is limitedly matched with the spline groove 1202 for transmitting power to the second spline sleeve 14, and a transmission member is arranged between the first spline sleeve 1301 and the input shaft of the transmission 10. The spline groove 1202 is provided with symmetrically distributed inclined portions 1203 for guiding the second spline sleeve 14 into the blind hole 1201; the rotation speed identification component is arranged at a position of the frame 101 close to the crushing portion 103, and is used to detect whether the crushing portion 103 is operating normally.

[0024] In the above scheme, it is intended to provide stable unidirectional power for the transmission 10. The reducer 11 changes the low torque and high speed provided by the power unit 102 into a high torque and low speed of the transmission sleeve 12. A blind hole 1201 is provided on the side of the transmission sleeve 12 away from the reducer 11. The blind hole 1201 is cylindrical as a whole. A truncated cone-shaped guide surface is provided on the side of the blind hole 1201 away from the reducer 11 to prevent hard collision with the second spline sleeve 14 when docking. The inclined portion 1203 is located on the side of the spline groove 1202 close to the second spline sleeve 14, and is used to guide the second spline sleeve 14 into the spline groove 1202 to make the docking process smoother. When the second spline sleeve 14 is successfully docked with the transmission sleeve 12, the transmission sleeve 12 drives the input shaft of the transmission 10 to rotate through the second spline sleeve 14, the first spline sleeve 1301 and the transmission member.

[0025] Combination Figure 2 , Fig.10 and Fig.11 As shown, the speed identification component includes: a power shaft 15 and a sleeve shaft 16, both of which are located in the middle of the frame 101, the sleeve shaft 16 is rotatably connected to the power shaft 15 and the frame 101, the sleeve shaft 16 is used to drive the crushing part 103, and a transmission member is arranged between the power shaft 15 and the power part 102; a first fixed disk 17, mounted on the power shaft 15, the sleeve shaft 16 is mounted with a second fixed disk 18, a torsion spring is fixedly connected between the second fixed disk 18 and the first fixed disk 17, so that the power shaft 15 drives the sleeve shaft 16 to rotate through the first fixed disk 17, the torsion spring and the second fixed disk 18; a limit block 19, fixedly connected to the second fixed disk 18, the first fixed disk 17 is spline-connected with a sliding sleeve 20, the sliding sleeve 20 is provided with a guide groove 2001, the limit block 19 slides in the guide groove 2001, and is used to make the sliding sleeve 20 and the first fixed disk 17 slide relative to each other; an oil circuit transmission component, arranged on the frame 101, and is used to control the movement of the second spline sleeve 14.

[0026] In the above scheme, it is intended to determine when the relative position of the bracket 4 and the frame 101 needs to be adjusted. Both the power shaft 15 and the sleeve shaft 16 can be made of high-quality alloy steel to give them higher toughness and strength. Both the limit blocks 19 and the guide grooves 2001 can be a number of evenly distributed circumferentially, and the limit blocks 19 slide in adjacent guide grooves 2001 to ensure the stability of the movement process of the sliding sleeve 20. The guide groove 2001 is an inclined slide groove for guiding the sliding sleeve 20 to slide. In the normal crushing process, the torsion spring between the second fixed disk 18 and the first fixed disk 17 is in a slightly charged state. When the power shaft 15 is driven by the transmission member and the power part 102 to rotate, the power shaft 15 drives the sleeve shaft 16 to rotate through the first fixed disk 17, the torsion spring and the second fixed disk 18, and then the sleeve shaft 16 drives the crushing part 103 to rotate to perform the crushing operation. When the power shaft 15 and the sleeve shaft 16 rotate relative to each other, the torsion spring accumulates force, and all the limit blocks 19 squeeze the corresponding guide grooves 2001 respectively, so that the sliding sleeve 20 slides along the first fixed plate 17 to detect whether the crushing efficiency decreases.

[0027] Combination Figure 3 , Figure 6 , Figure 7 and Fig.10 As shown, the oil circuit transmission component includes: a second hydraulic rod 21, which is installed on the frame 101, and the telescopic end of the second hydraulic rod 21 is fixedly connected with a sliding block 22, and the sliding sleeve 20 is provided with an annular protrusion, and the sliding block 22 is slidably matched with the annular protrusion of the sliding sleeve 20, so that when the sliding sleeve 20 and the first fixed plate 17 slide relative to each other, the telescopic end of the second hydraulic rod 21 is driven to move synchronously; an elastic hydraulic rod 23, which is fixedly connected to the frame 101 through a mounting plate, and the elastic hydraulic rod 23 and the second hydraulic rod 21 are connected through a pipeline, and the telescopic end of the elastic hydraulic rod 23 is fixedly connected to the second spline sleeve 14; a delayed reset component, which is arranged on the first mounting frame 5, and is used to delay the separation X of the transmission sleeve 12 and the second spline sleeve 14.

[0028] In the above scheme, the second spline sleeve 14 is controlled to move by oil circuit transmission. The sliding block 22 is always in contact with the annular protrusion of the sliding sleeve 20. When the sliding sleeve 20 moves, the annular protrusion of the sliding sleeve 20 drives the sliding block 22 to move, thereby pulling out the telescopic end of the second hydraulic rod 21, so that the hydraulic oil in the second hydraulic rod 21 flows through the pipeline to the elastic hydraulic rod 23. The elastic hydraulic rod 23 accumulates force, and the contraction of the telescopic end of the elastic hydraulic rod 23 drives the second spline sleeve 14 to dock with the transmission sleeve 12. When the rotation speed of the power shaft 15 and the sleeve shaft 16 is in the process of restoring stability, the elastic hydraulic rod 23 accelerates the flow of hydraulic oil into the second hydraulic rod 21 due to its own elastic force.

[0029] Combination Figure 4-Figure 9As shown, the time-delay reset assembly includes: a third hydraulic rod 24, which is installed on the first mounting frame 5, and the telescopic end of the third hydraulic rod 24 is squeezed and matched with the extrusion plate 7 to change the amount of hydraulic oil in the third hydraulic rod 24; a fourth hydraulic rod 25, which is installed on the second spline sleeve 14, and the fourth hydraulic rod 25 is connected to the third hydraulic rod 24 through a pipeline, and the telescopic end of the fourth hydraulic rod 25 is fixedly connected to a sliding cylinder 26, and a tension spring is fixedly connected between the sliding cylinder 26 and the second spline sleeve 14; a limit slider 27, which is slidably connected to the second spline sleeve 14 away from the On one side of the fourth hydraulic rod 25, a limiting portion 1204 connected to the blind hole 1201 is provided in the transmission sleeve 12, and the limiting slider 27 is limitedly matched with the limiting portion 1204 to fix the transmission sleeve 12 and the second spline sleeve 14. The limiting slider 27 is limitedly matched with the transmission sleeve 12 to control the triggering timing of the limiting slider 27. The limiting slider 27 is provided with an inclined slide groove, and the sliding cylinder 26 is fixedly connected with an extrusion column 28 which is extruded and matched with the inclined slide groove of the limiting slider 27 to change the position of the limiting slider 27 in the second spline sleeve 14.

[0030] In the above scheme, the purpose is to extend the reset time of the bracket 4 and ensure the stability of the movement process of the bracket 4. Initially, the telescopic end of the third hydraulic rod 24 is in a retracted state, the tension spring between the sliding cylinder 26 and the fixed plate of the telescopic end of the elastic hydraulic rod 23 (hereinafter referred to as the tension spring of the sliding cylinder 26) is initially in a stretched state, and the telescopic end of the fourth hydraulic rod 25 is in an extended state. Since the telescopic end of the third hydraulic rod 24 is squeezed by the plate 7 and cannot be extended, the tension of the tension spring is maintained. The limit slider 27 and the squeeze column 28 are both two centrally symmetrically distributed, which are used to ensure stability during the docking process. When the extrusion plate 7 moves, the telescopic end of the third hydraulic rod 24 loses its obstruction, and the tension spring of the sliding cylinder 26 drives it to squeeze the telescopic end of the fourth hydraulic rod 25. The telescopic end of the third hydraulic rod 24 slowly extends out, and there is a tendency of relative sliding between the sliding cylinder 26 and the second spline sleeve 14, but the limit slider 27 is limited by the transmission sleeve 12 and cannot extend until the second spline sleeve 14 moves to the extreme position of the blind hole 1201 in the transmission sleeve 12. At this time, the limit slider 27 corresponds to the position of the adjacent limit portion 1204, and the sliding cylinder 26 pushes the two limit sliders 27 through the two extrusion columns 28, so that the limit slider 27 is inserted into the adjacent limit portion 1204, fixing the second spline sleeve 14 and the transmission sleeve 12. In the process of resetting the extrusion plate 7, the extrusion plate 7 squeezes the telescopic end of the third hydraulic rod 24, so that the telescopic end of the fourth hydraulic rod 25 drives the sliding cylinder 26 to reset, and stretches the tension spring of the sliding cylinder 26 again to release the fixation of the second spline sleeve 14 and the transmission sleeve 12.

[0031] Working principle: When using this device to crush construction waste, the staff starts the power unit 102, the power unit 102 drives the power shaft 15 to rotate, the power shaft 15 drives the sleeve shaft 16 to rotate through the first fixed plate 17, the torsion spring and the second fixed plate 18, the sleeve shaft 16 drives the crushing unit 103 to work to perform the crushing action, and the preparation work is completed at this time.

[0032] After the preparation work is completed, the staff puts the construction waste into the opening on the upper side of the frame 101, and the construction waste falls onto the bracket 4. During the operation of the crushing unit 103, the crushing unit 103 gradually crushes the construction waste on the bracket 4, and then the crushed construction waste falls from the through slot of the bracket 4 and continues to be crushed. Finally, it is screened out of the frame 101 through the screen on the lower side, completing the normal crushing process. The staff collects the crushed construction waste and turns off the power unit 102 after use.

[0033] If the power shaft 15 and the sleeve shaft 16 rotate relative to each other during normal transmission, that is, the torsion spring between the first fixed plate 17 and the second fixed plate 18 is twisted and stored again, it proves that the resistance of the crushing part 103 is too large. If such a strong crushing process is continued, it will cause damage to the parts. At this time, the limit block 19 and the first fixed plate 17 are relatively displaced, and the limit block 19 squeezes the adjacent guide groove 2001, so that the sliding sleeve 20 slides along the first fixed plate 17 away from the frame 101. At this time, the annular protrusion of the sliding sleeve 20 pulls the sliding block 22 to move synchronously, so that the hydraulic oil in the second hydraulic rod 21 flows into the elastic hydraulic rod 23, and the telescopic end of the elastic hydraulic rod 23 pulls the second spline sleeve 14, which is driven by the round table Guided by the shaped guide surface and the inclined portion 1203, the second spline sleeve 14 is smoothly inserted into the spline groove 1202. At this time, the second spline sleeve 14 drives the first spline sleeve 1301 to rotate, so that the transmission device 10 transmits power to the threaded barrel 6. The threaded barrel 6 drives the extrusion plate 7 to move to the side away from the third hydraulic rod 24 to release the limit on the third hydraulic rod 24. As the second spline sleeve 14 continues to move, when the limit slider 27 is aligned with the adjacent limit portion 1204, the tension spring of the sliding cylinder 26 pulls the sliding cylinder 26, so that the extrusion column 28 squeezes the adjacent limit slider 27, fixes the transmission sleeve 12 and the second spline sleeve 14, and the telescopic end of the fourth hydraulic rod 25 contracts, and the telescopic end of the third hydraulic rod 24 extends.

[0034] The extrusion plate 7 performs a reciprocating motion, during which the extrusion plate 7 pushes the hydraulic oil in the cylinder 8 into the corresponding first hydraulic rod 3 and then withdraws it. The bracket 4 rises and then falls. When the bracket 4 rises, the crushing part 103 no longer contacts the construction waste on the bracket 4. The crushing part 103 only crushes the construction waste in the frame 101, preventing the construction waste from continuing to increase and causing excessive resistance of the crushing part 103 to affect the normal use of the power part 102, thereby saving energy consumption.

[0035] When the extrusion plate 7 is reset, the resistance of the crushing part 103 has been restored, the bracket 4 descends, and the crushing part 103 continues to crush the construction waste on the bracket 4. During the resetting process of the extrusion plate 7, the telescopic end of the third hydraulic rod 24 is squeezed to reset it, and the telescopic end of the fourth hydraulic rod 25 is extended, so that the limit slider 27 is separated from the limit of the adjacent limit part 1204, and at this time, the rotation of the power shaft 15 and the sleeve shaft 16 is restored to normal, and the torsion spring between the first fixed plate 17 and the second fixed plate 18 is gradually relaxed, and the power shaft 15 and the sleeve shaft 16 restore their initial relative relationship. The sliding sleeve 20 is reset and pushes the telescopic end of the second hydraulic rod 21 to reset through the sliding block 22, and the elastic hydraulic rod 23 is reset accordingly, so that the second spline sleeve 14 is reset, and the second spline sleeve 14 loses power and stops rotating. At this time, the transmission device 10 and subsequent transmission parts all stop working, completing the single problem handling. If this situation occurs again in the future, repeat the above actions. After use, turn off the power unit 102.

[0036] Embodiment 2: Based on Embodiment 1, Figure 6 and Figure 7 As shown, it also includes: an elastic telescopic rod 29, which is fixed to the side of the frame 101 close to the first mounting frame 5 through a mounting plate, and the second spline sleeve 14 is provided with a limiting hole that cooperates with the telescopic end of the elastic telescopic rod 29 to increase the telescopic speed of the elastic hydraulic rod 23.

[0037] Combination Figure 6 , Figure 7 and Fig.10 As shown, the flow area of ​​the hydraulic oil in the second hydraulic rod 21 is larger than the flow area of ​​the hydraulic oil in the elastic hydraulic rod 23 , so as to improve the sensitivity of the elastic hydraulic rod 23 .

[0038] In the above scheme, the purpose is to accelerate the movement and reset of the second spline sleeve 14 and increase the triggering speed. The telescopic end of the elastic telescopic rod 29 and the limiting hole on the second spline sleeve 14 are both hemispherical, which are used to limit the second spline sleeve 14. When the telescopic end of the elastic hydraulic rod 23 has a tendency to retract, the elastic telescopic rod 29 provides a limit for the fixed plate of the telescopic end of the elastic hydraulic rod 23, so that when it reaches a certain force storage condition, it is quickly triggered and stuck. In the process of resetting the telescopic end of the elastic hydraulic rod 23, the elastic telescopic rod 29 again provides a limit for the fixed plate of the telescopic end of the elastic hydraulic rod 23, so that the elastic hydraulic rod 23 stores force and prolongs the disengagement time of the second spline sleeve 14 and the transmission sleeve 12. By setting the comparative relationship of the flow area, the force storage speed of the telescopic end of the elastic hydraulic rod 23 is faster, and subsequent actions can be performed in the first time to protect the safety of the parts in the device.

[0039] What is described above is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
