Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of municipal engineering, and particularly relates to a solid waste crushing and transferring device for municipal road construction operation. BACKGROUND

[0002] A large amount of solid waste such as steel slag, coal gangue, and coagulated concrete blocks will be generated in municipal road construction operation. The solid waste needs to be transferred out of the construction site for recycling or classified landfill. However, the solid waste such as bricks and coagulated concrete blocks is large in size and occupies a large space, which is not convenient for transportation. Therefore, the solid waste is usually crushed by a crushing device and then transferred by a transferring device.

[0003] For example, a municipal road solid waste crushing and transferring device is disclosed in Chinese Patent No. CN110280348B, which includes a conveying frame provided with an air suction channel. An array of drive rods is arranged on one side of the conveying frame and connected with a servo motor. A crushing roller is arranged on the surface of the drive rod. An array of crushing rods is arranged on the surface of the crushing roller. The crushing roller is driven to rotate by a motor, so that the crushing rods on the crushing roller crush the solid waste. The solid waste is crushed in the conveying frame and discharged from the discharge port to the transferring device, so as to realize the crushing of the solid waste and the transfer of the crushed solid waste to the transferring device. During the solid waste transferring process, the solid waste is only transferred to the crushing and transferring device to realize the crushing of the solid waste and the automatic transfer of the crushed solid waste to the transferring device. The operation of transferring the crushed solid waste to the transferring device is omitted, so that the labor intensity of the operator is reduced and the work efficiency is improved compared with the prior art.

[0004] The solid waste crushing and transferring device provided by the application can more efficiently realize the crushing and transferring of solid waste, but has the disadvantage that: since the conveying frame plays a role of conveying solid waste from the feeding port of the conveying frame to the discharging port of the conveying frame and then onto the transferring equipment, that is, provides a conveying channel, and the plurality of crushing rollers are arranged in an array, the conveying frame must have a certain length in the direction from the feeding port to the discharging port, and the increase in the length of the conveying frame will inevitably increase the distance that the solid waste travels in the conveying channel of the conveying frame, and a large amount of crushed slag that cannot be sucked away by the fan will be generated in the process of crushing the solid waste, and when the crushing of the solid waste is completed, the crushed slag cannot continue to slide or roll in the conveying channel of the conveying frame because the volume of the crushed slag is small, the crushing rollers cannot contact the crushed slag, and the gravity of the crushed slag is relatively light, so that the crushed slag cannot overcome the friction between the crushed slag and the conveying frame under the action of the gravity of the crushed slag, and a large amount of the crushed slag will be left in the conveying channel of the conveying frame and be difficult to discharge.

[0028] To enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0029] like Figures 1-8 As shown in the figure, an embodiment of the present invention provides a solid waste crushing and transfer device for municipal road construction operations, including a conveying frame 1 on which a crushing roller 4 is rotatably mounted. A pad 5 located below the crushing roller 4 is elastically rotatably mounted in the conveying frame 1. A locking mechanism for locking the pad 5 is connected between the pad 5 and the conveying frame 1. The pad 5 has a crushing position when locked and a cleaning position when unlocked. In the cleaning position, the pad 5 elastically abuts against the crushing roller 4. At this time, the rotation of the crushing roller 4 impacts the pad 5, causing it to swing up and down so that the solid waste is discharged from the conveying frame 1 along the pad 5.

[0030] The solid waste crushing and transferring device for municipal road construction operation provided by the embodiment is used for crushing large-volume solid waste and transferring the crushed solid waste to a transferring equipment. The words related to directions and positions in the embodiment are relative to the drawings. Specifically, the conveying frame 1 provides a crushing space and a conveying channel for the solid waste. The crushing roller 4 cooperates with the conveying frame 1 to crush the solid waste in the conveying channel of the conveying frame 1. The cushion plate 5 is located inside the conveying frame 1. The conveying channel is enclosed by the top surface of the cushion plate 5 and the inner wall of the conveying frame 1. The front and rear sides of the cushion plate 5 are respectively in sliding fit with the front and rear inner walls of the conveying frame 1, so that the crushed slag generated in the crushing process cannot leak out from between the cushion plate 5 and the conveying frame 1. The crushing roller 4 is rotationally connected to the conveying frame 1 through the roller shaft 401. The front and rear ends of the roller shaft 401 are respectively rotationally penetrated through the front and rear side plates of the conveying frame 1. The roller shaft 401 is fixedly connected to the crushing roller 4. The roller shaft 401 is provided with a driven gear. The conveying frame 1 is provided with a driving motor 3. The driving motor 3 is a reduction motor or a servo motor. The output end of the driving motor 3 is connected with a driving gear (not shown in the figure). The driving gear and the driven gear are drivingly connected through a chain (not shown in the figure). The driving motor 3 can drive the driving gear to rotate, and then drive the driven gear and the crushing roller 4 to rotate through the chain. A plurality of crushing tooth plates are fixedly arranged on the outer circumferential surface of the crushing roller 4. The crushing tooth plates are used for extruding the solid waste. The rotation of the crushing roller 4 can crush the solid waste by the crushing tooth plates (the distance between the crushing roller 4 and the cushion plate 5 in the embodiment is the minimum distance between the free end of the crushing tooth plate and the cushion plate 5. The abutment between the crushing roller 4 and the cushion plate 5 is the abutment between the free end of the crushing tooth plate and the cushion plate 5).The conveying frame 1 is a hollow cuboid with both left and right ends open, the right open end of the conveying frame 1 is the feeding port 101, and the left open end is the discharging port 102, the crushing roller 4 rotates from the feeding port 101 to the discharging port 102, the solid waste enters the conveying channel in the conveying frame 1 from the feeding port 101 and is located on the top of the cushion plate 5, the bottom height of the feeding port 101 is greater than the top height of the cushion plate 5, and the bottom surface of the feeding port 101 is inclined downward toward the inside of the conveying frame 1, so that the solid waste can smoothly enter between the cushion plate 5 and the crushing roller 4 for crushing, the cushion plate 5 and the crushing roller 4 are elastically connected, the elastic rotation direction of the cushion plate 5 is toward the crushing roller 4, and the locking mechanism is used for position locking of the cushion plate 5, when the cushion plate 5 is locked, the cushion plate 5 is in a crushing station, and the cushion plate 5 has a distance from the crushing roller 4 to make the crushed solid waste pass through and be crushed in the distance, in work, the conveying frame 1 is inclined downward from the feeding port 101 to the discharging port 102, so that the crushed solid waste can slide out of the discharging port 102 along the top surface of the cushion plate 5, the transfer equipment is located below the discharging port 102, and then the solid waste sliding out of the discharging port 102 can directly fall into the transfer equipment, thereby saving the work of separately loading the solid waste onto the transfer equipment, and the large amount of crushed slag generated during crushing falls on the top surface of the cushion plate 5 and remains in the conveying frame 1, the crushed slag falling on the top surface of the cushion plate 5 is difficult to slide out of the discharging port 102, when the cushion plate 5 is unlocked by the locking mechanism, the cushion plate 5 is in a cleaning station, at this time, the cushion plate 5 is rotated toward the crushing roller 4 under the elastic rotation action of the cushion plate 5 and elastically abuts against the crushing roller 4, that is, the crushing tooth plate on the crushing roller 4 abuts against the top surface of the cushion plate 5, when the crushing roller 4 rotates, each crushing tooth plate follows the rotation and abuts against the top surface of the cushion plate 5 one by one, under the elastic rotation force of the cushion plate 5, the cushion plate 5 is continuously hit by the crushing tooth plate and repeatedly swings up and down, and then the crushed slag falling on the cushion plate 5 is repeatedly bounced up, because the conveying frame 1 is inclined, the cushion plate 5 is also inclined in the same direction, and then the crushed slag bounced up in the process of being hit and repeatedly swinging up and down has a force in the direction of the discharging port, so that the crushed slag can continuously move toward the discharging port until it is discharged from the conveying channel of the conveying frame 1 and will not remain in the conveying channel of the conveying frame 1.In the prior art, when the crushing of solid waste is completed, the volume of the crushed slag is small, the crushed block rod does not contact the crushed slag, and the gravity of the crushed slag is relatively light, so that the crushed slag cannot overcome the friction between the crushed slag and the conveying frame under the action of the gravity of the crushed slag, and the crushed slag cannot continue to slide or roll in the conveying channel of the conveying frame. Although the conveying frame can be adjusted to an inclination of 120° (because the design of the structure of the conveying frame and the existence of the transfer device at the discharge port 102 make it impossible for the inclination angle of the conveying frame to reach 180° or an angle close to 180°), under the condition that the inclination angle of the conveying frame is limited, the crushed slag cannot effectively overcome the friction between the crushed slag and the conveying frame by relying only on the gravity of the crushed slag, and a large amount of crushed slag is left in the conveying channel of the conveying frame and is difficult to discharge. The main innovation of the present application is that the setting of the base plate 5 and the locking mechanism is increased, so that the base plate 5 has two different working positions, and the cleaning position of the base plate 5 can clean the crushed slag left in the conveying channel of the conveying frame under the action of the rotation of the crushing roller 4, thereby solving the problem of the residual of the crushed slag.

[0031] In the present embodiment, the base plate 5 located below the crushing roller 4 is elastically rotated in the conveying frame 1, and the locking mechanism is arranged between the base plate 5 and the conveying frame 1, so that the base plate 5 has a crushing position when locked and a cleaning position when unlocked. In the crushing position state, the base plate 5 has a distance from the crushing roller 4, and at this time, the solid waste is located between the base plate 5 and the crushing roller 4 and is crushed under the action of the rotation of the crushing roller 4. A large amount of crushed slag is left in the conveying frame 1 during the crushing process. When the crushing is completed, the base plate 5 is adjusted to the cleaning position by the locking mechanism. In the cleaning position state, the base plate 5 is elastically abutted with the crushing roller 4 in the direction of the crushing roller 4. At this time, the rotation of the crushing roller 4 will hit the base plate 5 and make the base plate 5 swing up and down. The up-and-down swing of the base plate 5 and the vibration force generated when the crushing roller 4 hits the base plate 5 make the residual crushed slag smoothly discharge from the conveying channel of the conveying frame 1, realize the cleaning of the crushed slag, and prevent the residual of the crushed slag in the conveying channel of the conveying frame 1. Compared with the prior art, the present application increases the setting of the base plate 5, so that after the crushing of the solid waste is completed, the rotation of the crushing roller 4 hits the base plate 5 to make the base plate 5 swing up and down elastically, and then the residual crushed slag in the conveying channel of the conveying frame 1 is effectively cleaned to prevent the residual of the crushed slag.

[0032] Further, the direction from the feeding port 101 of the conveying frame 1 to the discharging port 102 of the conveying frame 1 is inclined downward, and the cushion plate 5 is inclined downward in the direction from the feeding port 101 to the discharging port 102, whether the cushion plate 5 is located in the crushing position or the cleaning position, so that the cushion plate 5 has a larger inclination angle relative to the conveying frame 1 during operation. The inclination angle of the conveying frame 1 in the prior art has a maximum angle limit, and the inclination of the conveying channel of the conveying frame 1 is the same as the inclination angle of the conveying frame 1. Compared with the prior art, the inclination of the conveying channel is larger than the inclination angle of the conveying frame 1, so as to reduce the friction of the solid waste in the conveying channel, and the crushed solid waste can be effectively discharged from the discharging port 102, thereby avoiding or reducing the residue of the crushed solid waste in the conveying channel. Therefore, the cushion plate 5 has unexpected technical effects.

[0033] In the embodiment, one end of the cushion plate 5 close to the discharging port 102 is rotationally connected to the conveying frame 1 through the rotating shaft 501, and the bottom of the other end of the cushion plate 5 away from the discharging port 102 is connected to the bottom of the inner cavity of the conveying frame 1 through the spring 6. The bottom of the spring 6 is fixedly connected to the bottom of the inner cavity of the conveying frame 1, and the top of the spring 6 is fixedly connected to the bottom of the cushion plate 5. The spring 6 is always in a compressed state, and the spring force of the spring 6 enables the cushion plate 5 to be elastically connected to the conveying frame 1. Of course, a torsional spring can be arranged on the rotating shaft 501 to replace the spring 6. The arrangement and function of the torsional spring are both prior art, and will not be described in detail.

[0034] In the embodiment, the bottom of the cushion plate 5 is fixedly provided with the abutting plate 7, and the abutting plate 7 rotates synchronously with the rotation of the cushion plate 5. In the crushing position, the bottom of the abutting plate 7 abuts against the bottom of the inner cavity of the conveying frame 1. The abutting plate 7 serves to limit and support the cushion plate 5. Under the joint action of the locking mechanism, the cushion plate 5 is hard connected to the conveying frame 1 when the cushion plate 5 is in the crushing position, so that the solid waste on the cushion plate 5 can be stably crushed by the crushing roller 4.

[0035] In the embodiment, the locking mechanism comprises a horizontal rod 10 slidingly inserted with the abutting plates 7, the number of the abutting plates 7 is two and oppositely arranged, the abutting plates 7 are provided with through holes 701 for the horizontal rod 10 to pass through, the two ends of the horizontal rod 10 pass through the through holes 701 of the two abutting plates 7 respectively, the horizontal rod 10 is a cylinder, the bottom surface of the through hole 701 slidingly abuts with the outer surface of the horizontal rod 10 so that the horizontal rod 10 can pull the abutting plate 7 to move downward when the horizontal rod 10 moves downward, and the horizontal rod 10 can slide relative to the through hole 701, the horizontal rod 10 is rotatably clamped with the locking rod 8 through the vertical rod 9, the vertical rod 9 is located between the two abutting plates 7, the bottom of the locking rod 8 extends to the outside of the conveying frame 1, the outer surface of the locking rod 8 is provided with a threaded segment 801 which is screwed with the bottom plate of the conveying frame 1, the locking rod 8 is pulled downward to pull the horizontal rod 10 to pull the abutting plate 7 downward to make the backing plate 5 rotate downward, and the threaded segment 801 is screwed with the bottom plate of the conveying frame 1 to make the backing plate 5 be locked to enter the crushing station, in the process of rotating the locking rod 8, the screw rod 8 continuously moves downward to drive the abutting plate 7 to continuously rotate downward, until the bottom of the abutting plate 7 abuts with the bottom of the inner cavity of the conveying frame 1. The operation time of locking the backing plate 5 can be reduced by the operation mode of first pulling the locking rod 8 and then rotating the locking rod 8, and the locking effect of the backing plate 5 is improved, when the backing plate 5 is unlocked to enter the cleaning station, the threaded segment 801 can be separated from the screwing relationship between the conveying frame 5 by reversely rotating the locking rod 8. Through the above design of the locking mechanism, the backing plate 5 can freely rotate up and down in the cleaning station, and the purpose of the backing plate 5 bouncing the crushed slag is achieved.

[0036] In the embodiment, the crushing roller 4 is located at the end of the backing plate 5 away from the rotating shaft 501, so that the backing plate 5 has greater vibration force.

[0037] In the embodiment, the vertical rod 9 and the horizontal rod 10 are integrally formed, the diameter of the lower half of the vertical rod 9 is greater than the diameter of the upper half of the vertical rod 9, the lower half of the vertical rod 9 is a disc 901 provided with an annular groove at the top, a plurality of balls 902 protruding from the annular groove are rollingly arranged in the disc 901, the locking rod 8 is sleeved outside the vertical rod 9, the inner cavity of the locking rod 8 is slidingly fitted with the outer surface of the disc 901, the bottom surface of the opening at the top of the locking rod 8 slidingly abuts with the top of the ball 902, so that the locking rod 8 can pull the vertical rod 9 to move downward. The setting of the ball 902 can reduce the rotation resistance of the rotating locking rod 8, and the operation is more labor-saving.

[0038] In this embodiment, the crushing roller 4, the pad plate 5, the abutting plate 7 and the locking mechanism jointly constitute a crushing mechanism, the number of the crushing mechanism is multiple and arranged in sequence along the direction from the feeding port 101 to the discharging port 102, the crushing rollers 4 in the multiple crushing mechanisms are drivingly connected through a transmission chain (not shown in the figure), so that the driving motor 3 can drive the multiple crushing rollers 4 to rotate together and in the same direction, the roller shaft 401 on each crushing roller 4 is provided with a driven gear 401, the transmission chain is arranged on each driven gear 401, and a driving gear is connected with the driven gear closest to the feeding port 101. The multiple crushing mechanisms are arranged to enable the solid waste to be crushed multiple times to improve the crushing quality of the solid waste, so that the size of the crushed solid waste is more uniform and the volume of the crushed solid waste is smaller.

[0039] Further, in the crushing position, the distance between the pad plate 5 and the crushing roller 4 in each crushing mechanism decreases in sequence along the direction from the feeding port 101 to the discharging port 102. The design has the following effects: first, since the smaller the distance between the pad plate 5 and the crushing roller 4 relative to the volume of the solid waste, the more difficult the solid waste is to be crushed, and the distance between the pad plate 5 and the crushing roller 4 decreases in sequence, which can reduce the size difference between the distance between the pad plate 5 and the crushing roller 4 and the volume of the solid waste, thereby enabling the solid waste to be crushed layer by layer and greatly reducing the difficulty of crushing the solid waste; second, since the distance between the pad plate 5 and the crushing roller 4 in the crushing mechanism closest to the feeding port 101 is the largest, the solid waste can pass through the pad plate 5 and the crushing roller 4 more easily, and the degree of crushing of the solid waste is the lowest, thereby preventing the solid waste from splashing and causing harm to the operator; third, when the solid waste passes through the first crushing mechanism and is crushed by the second crushing mechanism, the first crushing mechanism becomes a blocking mechanism, and when the second crushing mechanism is crushed and splashes, the splashed solid waste is blocked by the first crushing mechanism, thereby preventing the solid waste from passing through the feeding port and causing harm to the operator, and further improving the safety of the operator.

[0040] Further, in the crushing position, the inclination angle of each pad plate 5 increases in sequence along the direction from the feeding port 101 to the discharging port 102. Since the larger the inclination angle of the pad plate 5, the smaller the frictional resistance of the solid waste, through this design, as the degree of crushing of the solid waste deepens, the frictional resistance of the solid waste in the conveying channel gradually decreases, thereby the solid waste moves in the direction of the discharging port 102 and the resistance it receives is smaller, and the sliding speed is faster, so that the crushed solid waste is less likely to accumulate and remain in the conveying channel, and the efficiency of discharging the crushed solid waste is greatly improved.

[0041] In the embodiment, the height of each pad 5 decreases in sequence from the feeding port 101 to the discharging port 102, so that the pad 5 located downstream will not block the solid waste sliding down from the pad 5 upstream, and the height difference between the pads 5 makes the solid waste generate potential energy in the process of sliding from the pad 5 upstream to the pad 5 downstream, and when the solid waste slides down to the pad 5 downstream, the potential energy generated by the solid waste is partially converted into the power of the sliding of the solid waste, thereby promoting the sliding of the solid waste and increasing the sliding speed of the solid waste again, and improving the efficiency of discharging the solid waste from the discharging port 102; the gap 12 is arranged between each pad 5, because in order to enable the pad 5 to swing up and down, the gap 12 must be arranged between each two pads 5, that is, the gap 12 must exist, and since the height of each pad 5 decreases in sequence from the feeding port 101 to the discharging port 102, the existence of the gap 12 will not affect the discharge of the solid waste, the width of the gap 12 is smaller than the width of the crushed solid waste and greater than the width of the slag generated in the crushing process, and through the design, the gap 12 has an unexpected technical effect, that is, the slag generated in the crushing process of the solid waste can be filtered. Because the slag is small in volume and in the form of powder, in the process of transferring the solid waste, the slag is easy to scatter from the transfer equipment to the external environment, causing environmental pollution, or directly scattering on the road surface, causing road dust, so the solid waste should be loaded into the transfer equipment as much as possible together with the slag, and the existing technology cannot filter the slag in the process of transferring the solid waste to the transfer equipment. The specific implementation process of filtering the slag in the process of transferring the solid waste to the transfer equipment is as follows: in the process of crushing the solid waste, the crushed solid waste has a large volume and a large inertia, and in addition, the height difference between each two pads 5 and the width limitation of the gap 12 make the crushed solid waste slide along each pad 5 to the discharging port 102, and then finally slide out of the discharging port 102 to the transfer equipment, while the small-volume slag is small in volume, light in gravity, and small in inertia, so it cannot cross the gap 12 and is discharged downward from the gap 12 along the corresponding pad 5, thereby realizing automatic filtering of the slag, making the solid waste entering the transfer equipment more pure, and greatly reducing the amount of slag, thereby reducing the pollution to the environment.

[0042] Further, a plurality of discharge ports 103 corresponding to the gaps 12 are arranged on the bottom of the conveying frame 1, so that the slag discharged from the gaps 12 can be discharged through the discharge ports 103, and in order to realize the centralized collection of the slag, a collection box (not shown in the figure) is installed on the bottom of the conveying frame 1. The collection box covers each discharge port 103 to realize the collection of the slag.

[0043] Meanwhile, through the design of the above structure, when the solid waste is completed to be crushed, each base plate 5 is in the cleaning state by operating each locking mechanism respectively, the top surface of each base plate 5 is respectively in abutment with the corresponding crushing roller 4, and each crushing roller 4 is driven by the driving motor 3 to realize the impact on each base plate 5, so that each base plate 5 simultaneously vibrates and swings up and down, and then the residual crushed slag on each base plate 5 can slide off the corresponding base plate 5 and be discharged and collected in turn through the corresponding gap 12 and the discharge port 103. As can be seen, by arranging a plurality of base plates 5 and gaps 12 between the base plates 5, when cleaning the residual crushed slag in the conveying channel, the path length of the crushed slag walking in the conveying channel is greatly reduced, and each base plate 5 corresponds to a crushing roller 4, so that the vibration force of the base plate 5 is enhanced, so that the residual crushed slag in the conveying channel can be discharged from the base plate 5 more quickly and completely, and the effect of cleaning the residual crushed slag is greatly improved.

[0044] The operation sequence when unlocking each base plate 5 is sequentially performed from the direction of the discharge port 102 to the direction of the feeding port 101, so that each base plate 5 can be unlocked one by one in the case of a smaller gap 12 width (because when the base plate 5 is unlocked, the base plate 5 will be turned upward under the action of the spring 6, and after being turned upward, the base plate 5 located upstream will move in the downstream direction, so that the upstream base plate 5 will consume the width of the gap 12, and then easily block the rotation of the downstream base plate 5 or even cause the downstream base plate 5 to be unable to rotate).

[0045] In the embodiment, the lengths of the crushing tooth plates on each crushing roller 4 are different, so that each roller shaft 401 can be located on the same straight line, and the distance between the base plate 5 and the crushing roller 4 in each crushing mechanism can be sequentially reduced, and the action of each roller shaft 401 being located on the same straight line is to realize better driving of each roller shaft 401 by one driving motor 3.
