Description

Technical Field

[0001] The present invention relates to the technical field of construction waste treatment and recycling, and specifically to a production device and a production method for recycled aggregate of construction waste for roadbed hardening. Background Art

[0002] With the rapid development of urbanization, the generated construction waste has also increased, such as building structures, decoration materials, wood, steel bars, etc., which has caused great pressure on the urban environment.

[0003] Construction waste poses great risks to the environment and human health. For the environment, construction waste wastes a large amount of resources, occupies land area, contains toxic and harmful components, and will pollute the ecological environment. For humans, the sites occupied by construction waste will make the city generally in a closed state, reducing people's activity range and increasing health risks.

[0004] In line with the concept of people-oriented and sustainable development, most of the existing construction waste will be recycled for secondary use. Specifically, the construction waste is crushed into aggregate and then recycled according to the material type. Among them, concrete is the majority of construction waste. In order to avoid the generation of dust during crushing, most of this kind of construction waste will use a spraying device for dust reduction during crushing, so that the crushed construction waste has a certain water content. On the one hand, the water-containing construction waste is not conducive to storage, and on the other hand, it is not convenient for transportation and is prone to secondary pollution. Summary of the Invention

A driving member is rotatably installed on the action end of the electric telescopic rod. A slider is slidably installed on the driving member. The slider is rotatably connected to the first connecting shaft, and the slider is connected to the driving member through an elastic structure;

[0018] The driving assembly further includes a horizontal shaft installed on the driving member. A connecting member is slidably installed on the horizontal shaft. The connecting member is rotatably connected to the second connecting shaft.

[0019] As a further solution of the present invention: The elastic structure includes a horizontal shaft provided on the driving member and slidably connected to the slider. A first cylindrical spring is sleeved on the horizontal shaft. One end of the first cylindrical spring is connected to the slider, and the other end is connected to the driving member.

[0020] As a further solution of the present invention: It further includes:

[0021] A support is arranged on the base. A transverse moving plate capable of moving in the width direction of the conveying device is arranged on the support, and a plurality of sorting rods are arranged on the transverse moving plate along its length direction;

[0022] A limiting component is connected to the transverse moving plate, and the limiting component is used to keep the position of the transverse moving plate stable;

[0023] A triggering component is connected to the transverse moving plate. The triggering component cooperates with the limiting component and can enable the transverse moving plate to move along its length direction.

[0024] As a further scheme of the present invention: a sliding groove is arranged on the support, a sliding connection block is slidably installed in the sliding groove, and the sliding connection block is connected to a driving device arranged on the support;

[0025] The limiting component includes a connecting frame fixedly connected to the sliding connection block.

[0028] An inclined guiding surface is arranged on the triggering part.

[0029] A method for producing recycled aggregates of hardened roadbed construction waste using the production equipment described above includes the following steps:

[0030] Step 1: The two telescopic plate members block the discharge port of the crushing device through the driving component;

[0031] Step 2: Pour the construction waste into the crushing device;

[0032] Step 3: The two telescopic plate members move away from the discharge port through the driving component, so that under the action of the groove shaft structure and the driving component, the two telescopic plate members deflect relatively and extend outwards;

[0033] Step 4: The conveying device operates to spread the crushed construction waste on the conveying device;

[0034] Step 5: The transverse moving plate moves along the width direction of the conveying device to allocate the crushed construction waste. When the transverse moving plate moves to the end of the stroke, the triggering component acts to make the transverse moving plate move along its length direction. When the transverse moving plate moves in the reverse direction along the width direction of the conveying device, it allocates the crushed construction waste again, and at the same time, uses an external pump and blower to pump hot air to dry the crushed construction waste.

[0035] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0036] Through the set telescopic plate member and groove shaft structure, on the one hand, the telescopic plate member can be used to block the feeding port, so that the construction waste can be fully crushed to a predetermined diameter in the crushing device, which is convenient for subsequent processing and secondary use. On the other hand, when the telescopic plate member moves away from the feeding port, it can deflect, so that the two telescopic plate members form a "V" - shaped structure and act on the construction waste falling on the conveying device, enabling the construction waste to be evenly distributed on the conveying device, ensuring that the construction waste can be evenly heated during drying, and drying the moisture inside it, which is convenient for subsequent storage and transportation. At the same time, when the telescopic plate member deflects, the telescopic plate can move relative to the blocking plate towards the outside, so that when the telescopic plate member deflects in place, the telescopic plate can fit with the baffle, thus ensuring the evenness of the construction waste on the conveying device and improving the conveying capacity of the conveying device while spreading the construction waste;

[0037] Through the set driving component, transverse moving plate and dividing rod, when the dividing rod follows the driving device to move to the end of the stroke, several grooves can be formed on the construction waste. Under the action of the grooves, heat exchange can occur between the inside of the construction waste and the hot air, thereby improving the overall drying speed of the construction waste;

[0038] Through the set limiting component and triggering component, during the reciprocating movement of the transverse moving plate and the dividing rod, the dividing rod can allocate different grooves on the construction waste, increasing the number of grooves on the construction waste, and further improving the heat exchange effect between the inside of the construction waste and the hot air, and further improving the drying effect on the construction waste.

Detailed implementation manners

[0050] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0051] In addition, the elements in the present invention are referred to as "fixed to" or "disposed on" another element, and it can be directly on another element or there may also be an intermediate element. When an element is considered to be "connected" to another element, it can be directly connected to another element or there may be an intermediate element at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are only for illustrative purposes and do not represent the only implementation manners.

[0052] Please refer to Figures 1 to 10 , in the embodiment of the present invention, a production device for recycled aggregates of construction waste for subgrade hardening includes: a base 1, a connecting plate 3, and a driving assembly.

[0053] A crushing device 2 and a conveying device 28 are arranged on the base 1. A baffle 29 is arranged on the side of the conveying device 28 to prevent the crushed construction waste from falling from the side of the conveying device 28 after the crushing device 2 discharges materials;

[0054] The connecting plate 3 is connected to the discharge port of the crushing device 2. Two sets of telescopic plate members for blocking the discharge port are arranged on the connecting plate 3, and the telescopic plate members are connected to the connecting plate 3 through a groove shaft structure;

[0055] The groove shaft structure includes a first straight groove body 301 and a guiding groove arranged on the connecting plate 3. A first connecting shaft 601 connected to the telescopic plate member can slide in the first straight groove body 301, and a second connecting shaft 602 connected to the telescopic plate member can slide in the guiding groove;

[0056] The guiding groove includes a second straight groove body 302 arranged on the connecting plate 3 and an arc groove body 303 connected to the second straight groove body 302. The length of the second straight groove body 302 is the same as that of the first straight groove body 301. When the first connecting shaft 601 moves to the end of the first straight groove body 301 and the second connecting shaft 602 moves to the end of the second straight groove body 302, the second connecting shaft 602 can move along the arc groove body 303.

[0057] It should be noted that the ends of the first straight groove body 301 and the second straight groove body 302 are flush, so that when the second connecting shaft 602 is at the end of the first straight groove body 301 and the first connecting shaft 601 is at the end of the second straight groove body 302, the telescopic plate can maintain a state of being in contact with the discharge port. At this time, the discharge port can be blocked, so that when the crushing device 2 crushes construction waste, it is ensured that after the construction waste is crushed to a predetermined particle size, it is selectively discharged, that is, the construction waste can be recycled and crushed multiple times in the crushing device 2 to ensure the particle size after crushing and prevent the phenomenon that the construction waste is directly discharged without being crushed in place.

[0058] Further, after the crushing device 2 finishes crushing the construction waste, the driving assembly is controlled to act. At this time, the driving assembly can drive the two telescopic plates to move away from the discharge port along the length directions of the first straight groove body 301 and the second straight groove body 302 respectively. And because the lengths of the first straight groove body 301 and the second straight groove body 302 are the same, after the second connecting shaft 602 moves to the end of the first straight groove body 301, the first connecting shaft 601 just moves to the end of the second straight groove body 302. At this time, the second connecting shaft 602 is in a state of abutting against the end of the first straight groove body 301. When the driving assembly further acts, it can drive the first connecting shaft 601 to move along the arc groove body 303. At this time, the telescopic plate can be deflected, so that the two telescopic plates can form a "V" - shaped structure. During the process that the discharge port is opened for discharging materials and the conveying device 28 acts simultaneously, the "V" - shaped structure can be used to evenly spread the crushed construction waste into the conveying device 28, so that the hot air pumped out by the hot air pumping devices (not shown in the figure) arranged on both sides of the conveying device 28 can act on the construction waste evenly, ensuring that the construction waste is heated evenly and drying the moisture inside the dryer, which is convenient for subsequent storage and transportation.

[0059] Furthermore, after the crushed construction waste falls onto the conveying device 28, the construction waste can move under the drive of the conveying device 28. When the construction waste is in contact with the telescopic plate, because the telescopic plate is in an inclined state, the excessive construction waste can move along the length direction of the telescopic plate, so as to spread to both sides along the width direction of the conveying device 28, thereby improving the evenness of the dispersion of the construction waste on the conveying device 28.

[0060] With the above settings, on the one hand, the telescopic plate member can be used to block the blanking port, so that the construction waste can be fully crushed to a predetermined diameter in the crushing device 2, which is convenient for subsequent processing and secondary use. On the other hand, when the telescopic plate member moves away from the blanking port, it can deflect, so that the two telescopic plate members form a "V" - shaped structure and act on the construction waste falling on the transmission device 28, enabling the construction waste to be evenly distributed on the transmission device 28, ensuring that the construction waste can be evenly heated during drying to dry the moisture inside, which is convenient for subsequent storage and transportation.

[0061] Please refer to Figures 4 to 5 , the telescopic plate member includes a blocking plate 6 connecting the first connecting shaft 601 and the second connecting shaft 602. The inside of the blocking plate 6 is a hollow structure, and a telescopic plate 7 is slidably installed in the blocking plate 6. The telescopic plate 7 is connected to the connecting plate 3 through a guiding structure;

[0062] When the second connecting shaft 602 can move along the arc groove body 303, the guiding structure can drive the telescopic plate 7 to move towards the outside of the blocking plate 6. The guiding structure includes a side frame 5 arranged on the connecting plate 3. A third straight groove body 501 and an inclined groove body 502 are arranged on the side frame 5. The third straight groove body 501 has the same length as the first straight groove body 301;

[0063] The guiding structure further includes a fitting shaft 701 rotatably connected to the telescopic plate 7. The fitting shaft 701 can roll in the third straight groove body 501 and the inclined groove body 502.

[0064] When the blocking plate 6 is in a state of abutting against the discharge port, the fitting shaft 701 is at one end of the third straight groove body 501 far from the inclined groove body 502. At this time, the telescopic plate 7 is in a state of being retracted into the blocking plate 6, making the length of the entire telescopic plate member shorter, reducing its space occupancy rate, and facilitating subsequent disassembly, installation, maintenance and repair.

[0065] When the blocking plate 6 moves away from the discharge port, and when the second connecting shaft 602 moves to the end of the first straight groove body 301 and the first connecting shaft 601 moves to the end of the second straight groove body 302, the fitting shaft 701 just moves to the end of the third straight groove body 501. And during the deflection process of the blocking plate 6, the fitting shaft 701 can move along the inclined groove body 502. At this time, the telescopic plate 7 can move towards the outside of the blocking plate 6. When the first connecting shaft 601 moves to the end of the arc groove body 303 and the fitting shaft 701 moves to the end of the inclined groove body 502, the extension amount of the telescopic plate 7 reaches the maximum. At this time, the telescopic plate 7 is in a state of being attached to the baffle 29, so that the two telescopic plate members can cover the transmission device 28, enabling the crushed construction waste to be evenly and fully spread on the transmission device 28, and increasing the paving amount of the construction waste on the transmission device 28.

[0066] It should be noted that in the initial state, the telescopic plate member is in a state of abutting against the discharge port. At this time, the maximum length of the telescopic plate member can only be such that the sum of the lengths of the two sets of telescopic plate members is equal to the width of the conveying device 28. When the telescopic plate member deflects, the end of the telescopic plate member will move closer to the inside of the conveying device 28. At this time, if the length of the telescopic plate member does not change, excessive construction waste will accumulate on the conveying device 28 after moving to the end of the telescopic plate member, resulting in a large thickness of construction waste on both sides of the conveying device 28, which is not conducive to the drying of this part. In this embodiment, the telescopic plate 7 can move towards the outside of the blocking plate 6, so that when the telescopic plate member reaches the maximum deflection amount, the distance between the ends of the telescopic plates 7 on the two sets of telescopic plate members is equal to the width of the conveying device 28, so that the upper surface of the conveying device 28 can be completely and evenly filled with construction waste.

[0067] Through the above settings, when the telescopic plate member deflects, the telescopic plate 7 can move towards the outside relative to the blocking plate 6, so that when the telescopic plate member deflects and is in place, the telescopic plate 7 can be attached to the baffle 29, so that when spreading the construction waste, while ensuring the uniformity of the construction waste on the conveying device 28, the conveying capacity of the conveying device 28 is improved.

[0068] Please refer to Figures 1 to 4 , the driving assembly is connected to the two sets of telescopic plate members, and the driving assembly cooperates with the groove shaft structure, and can deflect and extend outward the two sets of telescopic plate members when the two sets of telescopic plate members move away from the discharge port;

[0069] The driving assembly includes an electric telescopic rod 4 rotatably installed on the crushing device 2. A driving member 9 is rotatably installed on the moving end of the electric telescopic rod 4. A slider 11 is slidably installed on the driving member 9. The slider 11 is rotatably connected to the first connecting shaft 601, and the slider 11 is connected to the driving member 9 through an elastic structure;

[0070] The driving assembly further includes a horizontal shaft 10 installed on the driving member 9. A connecting member 8 is slidably installed on the horizontal shaft 10. The connecting member 8 is rotatably connected to the second connecting shaft 602;

[0071] The elastic structure includes a horizontal shaft 13 provided on the driving member 9 and slidably connected to the slider 11. A first cylindrical spring 12 is sleeved on the horizontal shaft 13. One end of the first cylindrical spring 12 is connected to the slider 11, and the other end is connected to the driving member 9.

[0072] In the initial state, the first cylindrical spring 12 is in a compressed state, enabling the driving member 9 to abut against the slider 11. When the electric telescopic rod 4 operates, it can move through the driving member 9 and, supported by the first cylindrical spring 12, drive the slider 11 to move, causing the second connecting shafts 602 on the two telescopic plate members to move along the first straight groove body 301. At the same time, when the driving member 9 moves, the transverse shaft 10 drives the first connecting shaft 601 to move through the connecting member 8. And when the second connecting shaft 602 moves to the end of the first straight groove body 301 and the first connecting shaft 601 moves to the end of the second straight groove body 302, the slider 11 will stop moving. During the continued movement of the driving member 9, the first cylindrical spring 12 is further compressed, and at the same time, the transverse shaft 10 drives the connecting member 8 to continue moving, enabling the first connecting shaft 601 to move along the arc groove body 303 to drive the telescopic plate member to deflect, thus realizing the staggered movement of the first connecting shaft 601 and the second connecting shaft 602, enabling the telescopic plate member to deflect.

[0073] Please refer to Figures 6 to 10 , the construction waste recycling aggregate production equipment for subgrade hardening further includes: a bracket 14, a limiting component, and a triggering component.

[0074] The bracket 14 is arranged on the base 1, and a transverse moving plate 19 capable of moving in the width direction of the conveying device 28 is arranged on the bracket 14. A plurality of groups of deflector rods 20 are arranged along the length direction of the transverse moving plate 19. Specifically, a chute 1401 is arranged on the bracket 14, and a sliding connection block 16 is slidably installed in the chute 1401. The sliding connection block 16 is connected to a driving device 15 arranged on the bracket 14;

[0075] The limiting component is connected to the transverse moving plate 19, and the limiting component is used to keep the position of the transverse moving plate 19 stable;

[0076] The limiting component includes a connecting frame 17 fixedly connected to the sliding connection block 16. A cross bar 18 is arranged on the connecting frame 17. A follower plate 21 connected to the transverse moving plate 19 is slidably installed on the cross bar 18. A horizontal groove 2102 is arranged on the follower plate 21, and a group of limiting grooves 2101 are arranged at both ends of the horizontal groove 2102;

[0077] The limiting component further includes a hysteresis sleeve 24 connected to the cross bar 18. A connecting rod 23 is slidably installed in the hysteresis sleeve 24. The connecting rod 23 is connected to a second cylindrical spring 25 arranged in the hysteresis sleeve 24. And one end of the connecting rod 23 away from the second cylindrical spring 25 is rotatably installed with a fitting wheel 22, and the fitting wheel 22 can roll in the horizontal groove 2102 and the limiting grooves 2101.

[0078] During use, when the crushed construction waste is evenly spread on the transmission device 28, the driving device 15 will act. At this time, the driving device 15 can drive the transverse movement plate 19 to move along the width direction of the transmission device 28, and use the dividing rod 20 to allocate the construction waste. When the dividing rod 20 follows the driving device 15 to move to the end of the stroke, several grooves can be formed on the construction waste. Under the action of the grooves, heat exchange can be carried out between the inside of the construction waste and the hot air, thereby increasing the overall drying speed of the construction waste.

[0079] Among them, in the initial state, the second cylindrical spring 25 is in a compressed state. At this time, the engaging wheel 22 is located in one of the limiting grooves 2101. The engaging wheel 22 has the property of staying in the limiting groove 2101, which gives the transverse movement plate 19 a certain degree of stability, thereby ensuring the stability of the transverse movement plate 19 and the dividing rod 20 when moving along the width direction of the transmission device 28, making the allocated grooves parallel to the width direction of the transmission device 28, improving the smoothness of the hot air flow, and further enhancing the drying speed and drying effect.

[0080] Please refer to Figure 6 、 Figure 8 、 Figure 10 The trigger assembly is connected to the transverse movement plate 19, and the trigger assembly cooperates with the limiting assembly to enable the transverse movement plate 19 to move along its length direction;

[0081] The trigger assembly includes a trigger shaft 26 rotatably connected to the transverse movement plate 19, and the trigger shaft 26 is adapted to two groups of trigger members 27 provided on the transmission device 28;

[0082] The trigger member 27 is provided with an inclined guiding surface 2701.

[0083] When the transverse movement plate 19 moves to the end of the stroke, the trigger shaft 26 on the transverse movement plate 19 can abut against the inclined guiding surface 2701 on the trigger member 27, and under the drive of the inclined guiding surface 2701, the transverse movement plate 19 moves along the length direction of the cross bar 18. At this time, the engaging wheel 22 can engage with one of the limiting grooves 2101 and move to another limiting groove 2101 through the horizontal groove 2102. While ensuring the stability of the transverse movement plate 19 and the dividing rod 20 again, the dividing rod 20 moves a predetermined displacement amount, so that when the dividing rod 20 moves in the reverse direction, several grooves can be allocated on the construction waste again.

[0084] It should be noted that in this embodiment, the distance between two adjacent dividing rods 20 is marked as a, and the predetermined displacement amount of the above-mentioned dividing rod 20 movement is a / 2.

[0085] Through the above settings, during the reciprocating motion of the cross - moving plate 19 and the distributing rod 20, the distributing rod 20 can scrape out different grooves on the construction waste, increasing the number of grooves on the construction waste, and further improving the heat exchange effect between the interior of the construction waste and the hot air, and further enhancing the drying effect on the construction waste.

[0086] As an embodiment of the present invention, a method for producing recycled aggregate for roadbed hardening using the described production equipment is also proposed, including the following steps:

[0087] Step 1: Use the driving component to block the discharge port of the crushing device 2 with two sets of telescopic plate members;

[0088] Step 2: Pour the construction waste into the crushing device 2;

[0089] Step 3: Use the driving component to move the two sets of telescopic plate members away from the discharge port. Under the action of the groove - shaft structure and the driving component, the two sets of telescopic plate members deflect relatively and extend outwards;

[0090] Step 4: The transmission device 28 operates to spread the crushed construction waste on the transmission device 28;

[0091] Step 5: The cross - moving plate 19 moves along the width direction of the transmission device 28 to spread the crushed construction waste. When the cross - moving plate 19 moves to the end of the stroke, the triggering component operates to make the cross - moving plate 19 move along its length direction. When the cross - moving plate 19 moves in the reverse direction along the width direction of the transmission device 28, it spreads the crushed construction waste again, and at the same time, uses an external pump - blower to pump hot air to dry the crushed construction waste.

[0092] For those skilled in the art, it is obvious that the present invention is not limited to the details of the above - mentioned exemplary embodiments, and without departing from the spirit or basic characteristics of the present invention, the present invention can be implemented in other specific forms.
