Since the technology of the trash remover body 10 is mature, the trash remover is widely used in the market, and the structure of the trash remover having the rake teeth set, the chain and the driving member and the rake teeth set performing the rotation motion will not be further described, and the trash remover body 10 includes, but is not limited to, the grid trash remover disclosed in patent document (CN 219072241U). In addition, in the embodiment of the present application, the waste collecting member 102 is a collecting box with a blanking hole at the top.

It should be noted that, when the rake teeth group 101 with floating garbage lifted moves to the top of the annular guide rail group 103, the rake teeth group 101 will turn 180 ° along the annular guide rail group 103, and the rake teeth group 101 will not support the floating garbage lifted originally, and the floating garbage will fall freely under the action of gravity and fall into the waste collecting member 102 below.

It should be further noted that, after long-term use, the tooth side and root of the rake teeth set 101 are easy to adhere and accumulate sewage floats, small particles sand grains and grating residues, and if these dirt enter into the subsequent treatment equipment or damage the subsequent equipment, in view of this, the existing practice is to clean the rake teeth set 101 periodically, but because the whole volume of the fine grating trash remover is large and the rake teeth are many, the labor intensity of cleaning the rake teeth set 101 is high, and there is a risk of being scratched and scratched by the rake teeth in the cleaning process, so in the embodiment of the application, as shown in fig. 2 to 4, the fine grating trash remover with cleaning device further comprises a cleaning device 20, the cleaning device 20 is located above the waste collection piece 102, the cleaning device 20 comprises a plurality of cleaning pieces 201 and a frame 202, each cleaning piece 201 comprises a rod 2011, a plurality of bristles 2012 and a blocking hopper 2013, the bristles 2013 are fixed on the rod 2011, and the blocking hopper 2011 is connected with the rod 2011 and can be rotatably mounted on the outer side of the frame 2011. In the embodiment of the present application, the blocking hopper 2013 is U-shaped.

In the cleaning process, the rod 2011 and the cleaning member 201 are separated from the rake teeth 101 in an initial state, the rake teeth 101 stop moving, the rod 2011 moves a predetermined distance toward the rake teeth 101 and makes the bristles 2012 contact with the rake teeth 101, and accumulated dirt on the sides and the roots of the rake teeth 101 is cleaned along with the reciprocating movement of the cleaning member 201; in addition, during the reciprocating movement of the cleaning member 201, during the movement of the bristles 2012 in the direction away from the cleaner body 10, the dirt will move along with the bristles 2012 and finally fall into the blocking hopper 2013, after the bristles 2012 are cleaned for a predetermined time, the rod 2011 is far away from the rake teeth 101, then the rod 2011 is rotated for a predetermined angle, and the side of the blocking hopper 2013 close to the bristles 2012 faces the blanking port of the waste collecting member 102, so that the dirt falling into the blocking hopper 2013 will move along the bristles 2012 under the action of inertia and be thrown into the waste collecting member 102, thereby realizing the cleaning of the corresponding rake teeth 101, then the rake teeth 101 can be made to act, and the other rake teeth 101 are made to face the cleaning member 201, and the above actions are repeated until each rake teeth 101 are cleaned, thus completing the cleaning of the fine grid cleaner.

Further, since there are a plurality of cleaning members 201, in order to avoid that each cleaning member 201 is provided with a driving member, as shown in fig. 2, the cleaning device 20 further includes a connecting member 203 and a linear driving device 204, the connecting member 203 is fixedly connected with one end of each rod 2011 facing away from the bristles 2012, the fixed connection manner includes, but is not limited to, bolting or welding, the linear driving device 204 is rotatably mounted on the frame 202, and the push rod of the linear driving device 204 is fixedly connected with the connecting member 203 in a welding manner.

It should be noted that, in the embodiment of the present application, the linear driving device 204 is an air cylinder, the fine grid trash remover with a cleaning device further includes an air tank 30 for providing an air source for the linear driving device 204, the air tank 30 is disposed on the frame 202, and the linear driving device 204 is in pipeline communication with the air tank 30. In addition, by providing the connecting member 203, each rod 2011 is integrally connected, so that a driving member can drive each rod 2011 to move.

Further, in order to realize that the linear driving device 204 is rotatably mounted on the frame 202, as shown in fig. 2 and 5, the cleaning device 20 further includes a connection plate 205 and a rotation driving device 206, the rotation driving device 206 is further implemented as a rotation motor, the rotation driving device 206 is fixedly mounted on the frame 202 by a bolt connection manner, and two ends of the connection plate 205 are respectively fixedly connected with a rotation shaft of the rotation driving device 206 and a cylinder of the linear driving device 204, and the fixed connection manner includes, but is not limited to, threaded connection. The connection of the rotary drive 206 to the linear drive 204 is achieved by means of the connection plate 205.

Further, in order to achieve that the lever 2011 faces between the two corresponding rake teeth 101 in the normal state, as shown in fig. 5, the cleaning device 20 further includes a torsion spring 207, and two ends of the torsion spring 207 are fixedly connected with the body of the rotation driving device 206 and the connecting plate 205, respectively, and the fixing connection manner includes, but is not limited to, welding.

It should be noted that, the materials of the rod 2011 and the connecting piece 203 are preferably plastic, and the torsion force of the torsion spring 207 is greater than the sum of the weights of the cleaning piece 201 and the connecting piece 203. Under the torsion of the torsion spring 207, the lever 2011 normally faces between the two corresponding rake teeth 101.

Further, in order to avoid that when the rotation driving device 206 rotates the rod 2011 toward the waste collection member 102, the inertia of the rod 2011 before stopping is completely applied to the rotation driving device 206 when the rotation shaft of the rotation driving device 206 stops, as shown in fig. 2, the cleaning device 20 further includes a support 2021, where the support 2021 is fixedly connected to the frame 202, and the fixed connection manner includes, but is not limited to, welding or screwing, and when the rotation shaft of the rotation driving device 206 rotates, the cylinder of the linear driving device 204 is abutted against or separated from the support 2021; in addition, the support 2021 has a cushioning layer (not shown), which is preferably a rubber pad.

It should be noted that, when the torsion spring 207 is in an undeformed state, the cylinder of the linear driving device 204 is separated from the support 2021, and when the bristles 2012 clean the corresponding rake teeth 101 for a predetermined time, and the rotary driving device 206 drives the rod 2011 to rotate for a predetermined angle, the cylinder of the linear driving device 204 abuts against the support 2021. By providing the buffer layer for shock absorption, the cylinder of the linear driving device 204 is prevented from colliding with and being damaged by the support 2021 due to inertia.

Further, when the rod 2011 reciprocates, only when the bristles 2012 move toward the blocking hopper 2013, dirt is easy to push toward the blocking hopper 2013, and when the bristles 2012 move away from the blocking hopper 2013, the bristles 2012 either push the dirt to fall freely or fall on the next rake teeth set 101, in order to avoid this phenomenon, as shown in fig. 3, each cleaning member 201 further includes a sliding member 2014 and a spring 2015, a sliding slot 20111 is disposed on one side of the rod 2011 near the waste collecting member 102, the sliding slot 20111 is located on the bottom surface of the rod 2011, the sliding member 2014 is slidably disposed in the sliding slot 20111, two ends of the spring 2015 are respectively connected with the sliding member 2014 and the sliding slot 20111, and when the spring 2015 is in an undeformed state, the sliding member 2014 extends from one end of the rod 2011 with the bristles 2012 by a predetermined distance. More specifically, as shown in fig. 3 and 4, a side of the sliding member 2014 near the chute 20111 has a concave cavity 20141, and a cavity surface of the concave cavity 20141 is an arc surface.

It should be noted that, during the process that the rod 2011 gradually approaches the rake teeth set 101, the sliding member 2014 first abuts against the shaft seat 106 of the trash remover body 10, and moves when the bristles 2012 gradually move in a direction away from the blocking hopper 2013, the sliding member 2014 is blocked by the shaft seat 106 and stops moving further toward the rake teeth set 101, and at this time, the spring 2015 is pressed. It is easy to see that, since the slider 2014 fills the area under the bristles 2012 first, when the bristles 2012 move towards the hopper 2013 and sweep away dirt, the swept dirt will fall into the cavity 20141 of the slider 2014 under during the falling process, thereby avoiding the risk of the dirt falling to the next rake teeth set 101 when the bristles 2012 move away from the hopper 2013.

It should be further noted that, during the tightening of the spring 2015, the spring 2015 has an increasing elastic force, and the sum of the elastic force of the spring 2015 and the gravity of the cleaning member 201 and the connecting member 203 overcomes the partial torsion force of the torsion spring 207, so that the lever 2011 swings downward by a small angle during the approaching process to the rake teeth set 101, and in addition, swings upward by a small angle during the moving away of the lever 2011 from the rake teeth set 101, so that the cleaning capability of the rake teeth set 101 is further improved by the small swing during the reciprocating movement of the lever 2011.

In addition, in order to improve the cleaning capability, as shown in fig. 3 and 4, each rod 2011 is provided with a plurality of air nozzles 20112, the air nozzles 20112 are communicated with the air storage tank 30, and the air nozzles 20112 blow away the dirt with higher viscosity on the rake teeth set 101.

Further, since each rod 2011 is disposed in parallel and the connecting members 203 are disposed in an inclined manner, the length of each rod 2011 is different, the length of the rod 2011 near one side of the waste collecting member 102 is shortest, the rigidity is best, and the lengths of the remaining rods 2011 are sequentially longer and the rigidity is worse, so that the rod diameter of the rod 2011 near one side of the waste collecting member 102 is gradually increased from the rod diameter of the rod 2011 near the other side as shown in fig. 2.

In summary, the fine grid trash remover with the cleaning device according to the embodiment of the application is explained, which provides mechanical cleaning for the fine grid trash remover with the cleaning device, and is beneficial to reducing labor intensity, labor risk and the like.

It should be noted that in the embodiment of the application, the fine grid trash remover with the cleaning device has a simple structure, does not relate to complex manufacturing process and expensive materials, and has higher economical efficiency. Meanwhile, for manufacturers, the fine grid trash remover with the cleaning device is easy to produce, low in cost, beneficial to control of production cost and further beneficial to product popularization and use.
