Description

Technical Field

[0001] The invention belongs to the technical field of construction waste recycling and treatment, and in particular relates to a construction waste roller type crushing and treatment device. Background Art

[0002] Construction waste is mainly composed of concrete, bricks, rubble, etc. In order to improve the utilization rate of resources, various construction waste treatment equipment has been introduced. Among them, the roller crusher is a device specially used to crush construction waste into reusable small particles. However, in practical application, this equipment faces several key challenges: First of all, the working principle of the roller crusher is that two relatively rotating rollers exert an extrusion and grinding action on the material to achieve the purpose of crushing. By adjusting the gap between the two rollers, the particle size of the crushed material can be controlled. However, if the rotation speeds of the two rollers are inconsistent, the material will be unevenly stressed between the two rollers. This will not only cause some of the material to fail to be fully crushed, but also another part may be over-crushed, resulting in uneven particle size distribution of the final product, and the expected effect cannot be achieved. What's more serious is that asynchronous operation will increase the sliding friction of one roller relative to the other roller. Especially when handling hard materials, this additional friction will significantly increase the wear rate of the roller surface, thereby increasing maintenance costs and requiring more frequent replacement of wearing parts.

[0003] Secondly, the goal of crushing construction waste is to process it into a specific size for subsequent recycling. Since the construction waste initially put into the crusher varies in size, if the gap between the two rollers is set too wide, the material may not be completely crushed; on the contrary, if the gap is too narrow, it may cause material blockage or excessive crushing. In addition, the difference in the angle and position of the material entering will also cause the actual pressure acting on the material to be different even in the same gap, thus affecting the crushing effect. These problems make it difficult for the crushed construction waste to meet the requirements of subsequent recycling and reuse. Summary of the invention

[0004] In view of this, the purpose of the present invention is to provide a roller-type construction waste crushing and processing equipment to solve the problems existing in the above-mentioned background technology.

[0005] In order to solve the above technical problems, the first technical solution of the present invention is a roller crushing and processing equipment for construction waste, the processing equipment includes a frame and crushing rollers, the crushing rollers are arranged in pairs on the frame; a driving component, the driving component is used to allow the two crushing rollers in the same pair to rotate relative to each other; the driving component includes a passive gear transmission member arranged on both sides of the crushing roller, the passive gear transmission member has a matching active gear transmission member, the active gear transmission member located on the same side of the crushing roller is arranged in a colinear manner and is driven by the same transmission shaft; the passive gear transmission member and the active gear transmission member are intersecting axis transmission or staggered axis transmission.

[0006] Preferably, a first option for selecting a passive gear transmission member and a driving gear transmission member is as follows: when the passive gear transmission member and the driving gear transmission member are bevel gear transmission members, the passive gear transmission member and the driving gear transmission member are driven by intersecting axes, and the passive gear transmission member and the driving gear transmission member are both bevel gears; the passive gear transmission members located on the same side of the crushing roller have a nearest end and a farthest end, and the driving gear transmission members located on the same side of the crushing roller are respectively a first bevel gear and a second bevel gear, and the first bevel gear and the second bevel gear are simultaneously arranged at the nearest end or the farthest end.

[0007] Preferably, a second option for the passive gear transmission member and the active gear transmission member is as follows: when the passive gear transmission member and the active gear transmission member are worm gear transmission components, the passive gear transmission member and the active gear transmission member are staggered axis transmission, the passive gear transmission member is a worm wheel, and the active gear transmission member is a worm; the passive gear transmission members located on the same side of the crushing roller are respectively the first worm wheel and the second worm wheel, and the active gear transmission members located on the same side of the crushing roller are respectively the first worm wheel and the second worm wheel, the helical lines of the first worm wheel and the first worm wheel are in the same direction, the helical lines of the second worm wheel and the second worm wheel are in the same direction, and the helical lines of the first worm wheel and the second worm wheel are in opposite directions.

[0008] Preferably, a third option for the passive gear transmission member and the active gear transmission member is: when the passive gear transmission member and the active gear transmission member are face gear transmission members, the passive gear transmission member and the active gear transmission member are intersecting axis transmission, the passive gear transmission member is a face gear, and the active gear transmission member is a cylindrical gear meshing with the face gear; the passive gear transmission members located on the same side of the crushing roller have a nearest end and a farthest end, and the active gear transmission members located on the same side of the crushing roller are respectively a first cylindrical gear and a second cylindrical gear, and the first cylindrical gear and the second cylindrical gear are simultaneously arranged at the nearest end or the farthest end.

[0009] Preferably, the crushing rollers are optimized so that the gaps between them can be adjusted: the crushing rollers are relatively slidably arranged on the frame, and the gaps between the crushing rollers are adjusted by sliding; the driving gear transmission member is slidably arranged on the transmission shaft, and when the crushing rollers adjust the gaps, the driving gear transmission member slides on the transmission shaft, so that the driving assembly is suitable for driving different gaps between crushing rollers.

[0010] Furthermore, when the gap between the crushing rollers is adjusted, the active gear transmission member and the passive gear transmission member always remain in meshing: a sliding seat for mounting the crushing roller is provided on the frame, a mounting seat for mounting the active gear transmission member is provided on the transmission shaft, a connecting member is provided between the mounting seat and the sliding seat, and the connecting member and the mounting seat are rotatably connected; when the gap between the crushing rollers is adjusted, the active gear transmission member is driven by the sliding seat and the connecting member to slide on the transmission shaft, ensuring that the active gear transmission member and the passive gear transmission member can remain in meshing when the gap is adjusted.

[0011] Further, the third option for optimizing the passive gear transmission and the active gear transmission is as follows: when the first cylindrical gear and the second cylindrical gear are arranged at the nearest end, the first cylindrical gear and the second cylindrical gear are integrated to form a long cylindrical gear; the crushing rollers are arranged on the frame in a relatively sliding manner, and the gap between the crushing rollers is adjusted by sliding; the transmission gear transmission member slides on the long cylindrical gear to adjust the gap between the crushing rollers, while ensuring the meshing of the active gear transmission member and the passive gear transmission member.

[0012] Preferably, a screen is added to ensure that the material is crushed to a qualified size: the processing equipment includes a screen, which is obliquely arranged at the bottom end of the crushing roller, and the screen is used to crush and screen the construction waste into particles with a size that meets the specifications and particles with a size that does not meet the specifications; a discharging belt, which is used to send materials with a particle size that meets the specifications out of the processing equipment, and the discharging belt is arranged at the bottom of the screen, and the transmission direction of the discharging belt is opposite to the inclination direction of the screen; a feeding belt, which is used to send materials with a particle size that does not meet the specifications out of the processing equipment for secondary crushing, and the feeding belt is arranged at the bottom of the screen, and the transmission direction of the feeding belt is the same as the inclination direction of the screen.

[0013] In order to solve the above technical problems, the second technical solution of the present invention is a method for using a construction waste roller crushing and processing device, and the construction waste roller crushing and processing device described in schemes 1 to 3 is selected by applying the passive gear transmission member and the active gear transmission member in the first technical solution. The method of use includes adjusting the gap between the crushing rollers, and the steps of adjusting the gap between the crushing rollers are as follows: S1. The position of the crushing roller is changed by adjusting the sliding seat arranged on the frame. The sliding seat allows the crushing roller to move relative to the frame so as to adjust the gap between the two crushing rollers. S2. Since the driving gear transmission part is slidably arranged on the transmission shaft, when the position of the crushing roller is adjusted, the driving gear transmission part is synchronously driven to slide on the transmission shaft through the connecting part; while adjusting the gap between the crushing rollers, the driving gear transmission part and the passive gear transmission part can maintain a good meshing state.

[0014] In order to solve the above technical problems, the third technical solution of the present invention is a method for using a construction waste roller crushing and processing equipment, and the construction waste roller crushing and processing equipment described in the third technical solution is selected by applying the optimized passive gear transmission part and the active gear transmission part in the first technical solution. The method of use includes adjusting the gap between the crushing rollers, and the steps of adjusting the gap between the crushing rollers are as follows: S1. Since the long cylindrical gear and the passive gear transmission member are not connected, the active gear transmission member and the passive gear transmission member are separated to release the meshing state of the active gear transmission member and the passive gear transmission member; S2. The position of the crushing roller is changed by adjusting the sliding seat arranged on the frame. The sliding seat allows the crushing roller to move relative to the frame so as to adjust the gap between the two crushing rollers; S3, bringing the driving gear transmission member and the passive gear transmission member closer together to achieve re-engagement of the driving gear transmission member and the passive gear transmission member.

[0015] The technical effects of the present invention are mainly reflected in the following aspects: The synchronous rotation between the crushing rollers is ensured by adopting the transmission mode of bevel gear, worm gear or face gear and cylindrical gear combination. This avoids the problem of uneven force on the material, uneven particle size distribution and additional wear caused by the speed difference; due to the reduction of relative sliding friction, especially the self-locking function when using worm gear transmission, it not only reduces the roller surface wear rate, but also extends the service life of the equipment and reduces maintenance costs.

[0016] The crushing rollers are designed to be mounted on the sliding seat on the frame in a relatively sliding manner, allowing the gap between the two crushing rollers to be adjusted quickly and accurately as needed to meet the processing requirements of materials of different sizes. Regardless of the transmission method, it is ensured that even when adjusting the gap between the crushing rollers, the active gear transmission part and the passive gear transmission part can maintain a good meshing state, thereby maintaining stable and efficient power transmission.

DETAILED DESCRIPTION

[0018] The specific implementation methods of the present invention are further described in detail below in conjunction with the accompanying drawings to make the technical solution of the present invention easier to understand and grasp. In the embodiments, it should be understood that the orientation or position relationship indicated by the terms "middle", "upper", "lower", "top", "right side", "left end", "above", "back", "middle", etc. is based on the orientation or position relationship shown in the accompanying drawings, which is only for the convenience of describing the present invention, and does not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation of the present invention. In addition, in this specific implementation method, if the connection or fixing method between the components is not particularly specified, the connection or fixing method can be fixed by bolts or pins commonly used in the prior art, or by pin connection, etc., and therefore, it will not be described in detail in this embodiment.

[0019] Embodiment 1 See also Figure 1This embodiment discloses a roller crushing and processing equipment for construction waste, the processing equipment includes a frame 1 and crushing rollers 2, the crushing rollers 2 are arranged in pairs on the frame 1; a driving assembly 3, the driving assembly 3 is used to make the two crushing rollers 2 of the same pair rotate relative to each other; the driving assembly 3 includes a passive gear transmission 31 arranged on both sides of the crushing roller 2, the passive gear transmission 31 has a matching active gear transmission 32, the active gear transmission 32 located on the same side of the crushing roller 2 is arranged in a colinear axis and driven by the same transmission shaft 33; it ensures that there is no speed difference between the same pair of crushing rollers 2, thereby avoiding the problem of uneven force on the material and uneven particle size distribution caused by asynchronous speed. At the same time, due to the reduction of relative sliding friction, the roller surface wear rate is also reduced, the service life of the equipment is extended, and the maintenance cost is reduced.

[0020] The passive gear transmission member 31 and the active gear transmission member 32 are intersecting axis transmission or staggered axis transmission. Explanation on intersecting axis transmission or staggered axis transmission: There are many types of gears, and the most common classification method is based on the gear axis type; they are generally divided into three types: parallel axis, intersecting axis and staggered axis. Among them, parallel axis gears include spur gears, helical gears, internal gears, racks and helical racks, etc.; intersecting axis gears: there are straight bevel gears, arc bevel gears, zero-degree bevel gears, etc.; staggered axis gears: there are staggered axis helical gears, worm gears, hypoid gears, etc.

[0021] See also Figure 4 , Option 1 for the passive gear transmission 31 and the active gear transmission 32: When the passive gear transmission 31 and the active gear transmission 32 are bevel gear transmission components, the passive gear transmission 31 and the active gear transmission 32 are intersecting axis transmission; bevel gears (also called bevel gears) are mainly used for power transmission between intersecting axes, and are usually used in applications where the direction of force needs to be changed, such as in the equipment in this embodiment, to optimize the power transmission direction between the crushing rollers 2, ensuring that there is no speed difference between the same pair of crushing rollers 2 while being able to rotate relative to each other. The passive gear transmission 31 and the active gear transmission 32 are both bevel gears; the passive gear transmission 31 located on the same side of the crushing roller 2 has a proximal end and a distal end, and the active gear transmission 32 located on the same side of the crushing roller 2 are respectively the first bevel gear 41 and the second bevel gear 42, and the first bevel gear 41 and the second bevel gear 42 are simultaneously arranged at the proximal end or the distal end.

[0022] See also Figure 5, Option 2 for the passive gear transmission 31 and the active gear transmission 32: When the passive gear transmission 31 and the active gear transmission 32 are worm gear transmission components, the passive gear transmission 31 and the active gear transmission 32 are staggered shaft transmission, the passive gear transmission 31 is a worm wheel, and the active gear transmission 32 is a worm; worm gear transmission is a common mechanical transmission method, suitable for occasions where power needs to be transmitted between staggered shafts; the contact between the worm wheel and the worm is sliding friction, which makes it have a self-locking function (that is, power can only be transmitted from the worm to the worm wheel, and vice versa), especially when processing hard materials, it can avoid safety hazards caused by accidental reversal. Worm gear transmission can achieve a large speed change ratio in a relatively small space, which is very suitable for use in construction waste crushing equipment that requires a compact design. The passive gear transmission members 31 located on the same side of the crushing roller 2 are respectively a first worm wheel 51 and a second worm wheel 52, and the active gear transmission members 32 located on the same side of the crushing roller 2 are respectively a first worm 53 and a second worm 54, the helical lines of the first worm wheel 51 and the first worm 53 are in the same direction, the helical lines of the second worm wheel 52 and the second worm 54 are in the same direction, and the helical lines of the first worm 53 and the second worm 54 are in opposite directions.

[0023] See also Figure 6 , Option 3 of the passive gear transmission member 31 and the active gear transmission member 32 (this technology refers to the end face gear mechanism): When the passive gear transmission member 31 and the active gear transmission member 32 are face gear transmission components, the passive gear transmission member 31 and the active gear transmission member 32 are intersecting axis transmission, the passive gear transmission member 31 is a face gear, and the active gear transmission member 32 is a cylindrical gear meshing with the face gear; the face gear is a special type of gear that can mesh with other types of gears (such as cylindrical gears) to achieve power transmission between intersecting axes; the design of the face gear enables it to provide efficient force transmission in a compact space and can change the direction of force in different directions. The passive gear transmission members 31 located on the same side of the crushing roller 2 have a proximal end and a distal end, and the active gear transmission members 32 located on the same side of the crushing roller 2 are respectively a first cylindrical gear 61 and a second cylindrical gear 62, and the first cylindrical gear 61 and the second cylindrical gear 62 are simultaneously arranged at the proximal end or the distal end.

[0024] The above-mentioned options 1 to 3 of the passive gear transmission 31 and the active gear transmission 32: by using bevel gear transmission, worm gear transmission and face gear and cylindrical gear combination transmission, efficient and accurate power transmission is achieved, ensuring that the two crushing rollers 2 can rotate synchronously, avoiding the problems of uneven force on the material, uneven particle size distribution and additional wear caused by the speed difference, wherein the worm gear transmission mechanism reduces vibration and noise. A variety of transmission schemes based on bevel gears, worm gears and face gears and cylindrical gears are provided, providing flexible options for different application scenarios, and increasing the adaptability and versatility of the equipment.

[0025] See also Figure 1 , Figure 3 In order to make the equipment adaptable to the processing requirements of materials of different sizes and ensure that the drive assembly 3 can work continuously and stably during the adjustment process, the crushing rollers 2 are optimized to enable gap adjustment: the crushing rollers 2 are relatively slidably arranged on the frame 1, and the gap between the crushing rollers 2 is adjusted by sliding; the driving gear transmission member 32 (such as a bevel gear, a worm gear or a cylindrical gear) is slidably arranged on the transmission shaft 33, and is designed to slide on the transmission shaft 33 to adapt to the change of the gap between the crushing rollers 2. When the crushing roller 2 adjusts the gap, the driving gear transmission member 32 slides on the transmission shaft 33, allowing the drive assembly 3 to be suitable for driving different gaps between the crushing rollers 2. When the gap of the crushing roller 2 is adjusted, the active gear transmission member 32 and the passive gear transmission member 31 always remain in meshing: a sliding seat 34 for mounting the crushing roller 2 is provided on the frame 1, and a mounting seat 35 for mounting the active gear transmission member 32 is provided on the transmission shaft 33, a connecting member is provided between the mounting seat 35 and the sliding seat 34, and a rotational connection is provided between the connecting member and the mounting seat 35; when the gap of the crushing roller 2 is adjusted, the active gear transmission member 32 is driven by the sliding seat 34 and the connecting member to slide on the transmission shaft 33, ensuring that the active gear transmission member 32 and the passive gear transmission member 31 can remain in meshing when the gap is adjusted.

[0026] Specifically, the above allows the operator to adjust the gap between the crushing rollers 2 very accurately, so as to better control the particle size of the crushed product and meet the needs of different application scenarios. By allowing the active gear transmission member 32 to slide on the transmission shaft 33 while maintaining engagement with the passive gear transmission member 31, it is ensured that no matter how the gap between the crushing rollers 2 changes, the power transmission is always stable and reliable, avoiding the problem of power transmission interruption or reduced efficiency due to gap adjustment. At the same time, the use of a rotating connection connector not only simplifies the structural design, but also enhances the mechanical stability of the entire system and reduces the risk of failure due to wear or loosening of parts.

[0027] See also Figure 2 , add a screen 11 to ensure that the material is crushed to a qualified size: the processing equipment includes a screen 11, which is tilted and arranged at the bottom of the crushing roller 2. The tilted screen 11 helps to accelerate the screening process of the material by gravity, and can make smaller particles pass through the screen 11 faster. The screen 11 is used to crush and screen the construction waste into particles that meet the specifications and particles that do not meet the specifications; the discharge belt 12 is used to send the material with the particle size that meets the specifications out of the processing equipment. The discharge belt 12 is arranged at the bottom of the screen 11, and the transmission direction of the discharge belt 12 is opposite to the tilt direction of the screen 11; this means that when the small particles that meet the specifications pass through the screen 11, they will be collected on the discharge belt 12 and transported out in the direction opposite to the tilt direction of the screen 11, so as to leave the processing equipment and enter the next stage of application or storage. The feeding belt 13 is used to send materials whose particle size does not meet the specifications out of the processing equipment for secondary crushing. The feeding belt 13 is arranged at the bottom end of the screen 11. The transmission direction of the feeding belt 13 is the same as the inclination direction of the screen 11, ensuring that these substandard materials can be smoothly transported to the secondary crushing area for further processing.

[0028] Embodiment 2 This embodiment discloses a construction waste roller crushing and processing device. The processing device of this embodiment optimizes the original selection scheme 3 of the passive gear transmission member 31 and the active gear transmission member 32 of the first embodiment, as follows: See also Figure 6When the first cylindrical gear 61 and the second cylindrical gear 62 are arranged at the nearest end, the first cylindrical gear 61 and the second cylindrical gear 62 are integrated to form a long cylindrical gear, which is specifically a crown gear (named because its tooth surface is formed by splines and the gear has a crown shape), which simplifies the complexity of the transmission system, reduces possible failure points, and improves the transmission efficiency; the crushing rollers 2 are arranged on the frame 1 in a relatively sliding manner, and the gap between the crushing rollers 2 is adjusted by sliding; the crushing rollers 2 are still installed on the frame 1 in a relatively sliding manner, allowing the operator to adjust the gap between the two crushing rollers 2 as needed. In this way, the processing requirements of materials of different sizes can be flexibly responded to, ensuring the best crushing effect. The adjustment of the gap between the crushing rollers 2 is achieved by sliding the transmission gear transmission member on the long cylindrical gear, while ensuring the meshing of the driving gear transmission member 32 and the driven gear transmission member 31. When adjusting the gap between the crushing rollers 2, the transmission gear transmission member (i.e., the driving gear transmission member 32 meshing with the face gear) can slide on the long cylindrical gear. This not only enables flexible adjustment of the gap between the crushing rollers 2, but also ensures that the active gear transmission 32 and the passive gear transmission 31 (i.e., the face gear) always maintain the correct meshing state during the entire adjustment process. Allowing the driving gear transmission to slide on the long cylindrical gear when adjusting the gap ensures that the active gear transmission 32 and the passive gear transmission 31 can maintain a good meshing state regardless of how the gap between the crushing rollers 2 changes; this feature is essential for maintaining stable power transmission, especially when the gap between the crushing rollers 2 is frequently adjusted.

[0029] Embodiment 3 This embodiment discloses a method for using a construction waste roller crushing and processing device, using the construction waste roller crushing and processing device described in the first embodiment, the method includes adjusting the gap between the crushing roller 2, and the steps for adjusting the gap between the crushing roller 2 are as follows: S1. Adjust the sliding seat 34 to change the position of the crushing roller 2: By operating the sliding seat 34 provided on the frame 1, the position of the crushing roller 2 relative to the frame 1 can be changed. The design of the sliding seat 34 allows the crushing roller 2 to move in a specific direction, thereby accurately adjusting the gap size between the two crushing rollers 2. This ensures that the appropriate crushing gap can be adjusted according to materials of different sizes.

[0030] S2, synchronously drives the driving gear transmission member 32 to slide: The driving gear transmission member 32 is slidably arranged on the transmission shaft 33, so when the position of the crushing roller 2 changes, the driving gear transmission member 32 can be synchronously driven to slide on the transmission shaft 33 through the connecting member. The purpose of this is to ensure that when the gap between the crushing roller 2 is adjusted, the driving gear transmission member 32 and the driven gear transmission member 31 can always maintain a good meshing state, thereby ensuring the continuity and stability of power transmission.

[0031] Embodiment 4 This embodiment discloses a method for using a construction waste roller crushing and processing device, using the construction waste roller crushing and processing device described in the second embodiment, and the method includes adjusting the gap between the crushing rollers 2, and the steps for adjusting the gap between the crushing rollers 2 are as follows: S1, releasing the meshing of the driving gear transmission member 32 and the driven gear transmission member 31: In this embodiment, since the long cylindrical gear and the passive gear transmission member 31 are not directly connected, before adjusting the gap between the crushing roller 2, it is first necessary to separate the active gear transmission member 32 and the passive gear transmission member 31 to release the meshing state between them and prevent unnecessary wear or damage to the gears during the adjustment process.

[0032] S2. Adjust the sliding seat 34 to change the position of the crushing roller 2: Next, the position of the crushing roller 2 is changed by adjusting the sliding seat 34 provided on the frame 1 according to the same steps as in the third embodiment. The sliding seat 34 allows the crushing roller 2 to move relative to the frame 1 so as to adjust the gap between the two crushing rollers 2. This process is similar to that in the third embodiment, but in this case it is performed in a state where the gears are not meshed.

[0033] S3, re-engage the driving gear transmission member 32 and the driven gear transmission member 31: After the adjustment of the gap between the crushing rollers 2 is completed, the driving gear transmission 32 and the driven gear transmission 31 are brought closer together to make them mesh again. This step requires careful operation to ensure that the two gears are accurately aligned to avoid any possible mechanical failure and ensure that the subsequent power transmission is smooth and unimpeded.

[0034] In this embodiment, it is proposed to release the meshing of the driving gear transmission member 32 and the driven gear transmission member 31 before adjusting the gap of the crushing roller 2 to prevent unnecessary wear or damage, which embodies the concept of preventive maintenance.

[0035] In addition, as common knowledge in the industry, the sliding seat 34 mentioned above can be driven by a sliding table and a telescopic cylinder. The above is common knowledge, so its principle and structure will not be described in detail.

[0036] Of course, the above are only typical examples of the present invention. In addition, the present invention may also have many other specific implementations. All technical solutions formed by equivalent replacement or equivalent transformation fall within the scope of protection required by the present invention.
