Description

Technical Field

[0001] The present invention relates to the technical field of grid dirt removal machines, and particularly relates to a grid dirt removal machine with a crushing device. Background Technique

[0002] A grid dirt removal machine is a special water treatment device that can continuously and automatically intercept and remove various shaped sundries in a fluid. The sundries contained in sewage vary in type. Generally, a crushing device can be used to pre-crush the larger-sized sundries to facilitate subsequent cleaning of the sundries by the grid dirt removal machine.

[0003] Currently, generally, a power device is used to drive a driving roller to rotate, and the driving roller then drives the driven roller to rotate synchronously. Through the mutually meshing gears arranged on the surfaces of the two rollers, the sundries can be crushed.

[0004] During the process of crushing sundries with the crushing rollers, if the sewage contains long strip-shaped sundries, the strip-shaped sundries are likely to rotate synchronously with the two crushing rollers, and thus are easily wound around the outer surface of the crushing rollers. After the crushing rollers rotate for a long time, the strip-shaped sundries on their outer surfaces will become tighter and tighter, which is likely to limit the rotation of the crushing rollers, and thus affect the effect of crushing other sundries. Therefore, it is necessary to propose a grid dirt removal machine with a crushing device. Summary of the Invention

[0005] The purpose of the present invention is to provide a grid dirt removal machine with a crushing device to solve the problems raised in the above background technique.

[0006] To solve the above technical problems, the technical solution adopted by the present invention is:

[0007] A grille sewage cleaner with a crushing device, comprising a sewage cleaner main body; a crushing roller set is arranged at one end of the sewage cleaner main body, a pair of fixed frames are fixedly installed on both sides of the sewage cleaner main body, each fixed frame is respectively rotationally connected to the top and bottom of the crushing roller set, a control panel is fixedly connected to one side of the sewage cleaner main body at the top of the fixed frame, a motor is fixedly installed at the top of the fixed frame on one side of the sewage cleaner main body, an output shaft of the motor extends into the interior of the fixed frame and is fixedly connected to the top end of the crushing roller set, a plurality of crushing bars are arranged on the periphery inside the crushing roller set, and each crushing bar extends out of the interior of the crushing roller set. A plurality of cutting knives are arranged inside the crushing roller set, each cutting knife extends out of the interior of the crushing roller set, and each cutting knife is arranged in a staggered manner with each crushing bar. An adjusting component for adjusting the movement of the cutting knife and the crushing bar is arranged on the inner side of each cutting knife. Each adjusting component includes a connecting block, each connecting block is fixedly connected to the inner surface of the crushing bar respectively. A plurality of second springs are fixedly installed inside the crushing roller set, the outer side of each second spring is fixedly connected to the inner surface of each crushing bar respectively, and each second spring is respectively located at the top and bottom of each connecting block. An extrusion block is fixedly installed on the inner surface of each cutting knife, a plurality of first springs are fixedly installed inside the crushing roller set, each first spring is fixedly connected to the top of each extrusion block respectively. A push block is arranged between each connecting block and each extrusion block, the surface of each push block close to each connecting block is set to be bevel-shaped, and each bevel surface is in fit with the connecting block. The surface of each extrusion block close to each push block is set to be bevel-shaped, and each bevel surface is in fit with the push block.

[0008] When the main body of the decontamination machine is working, it can adsorb the sundries in the sewage from one end and drive the sundries close to the inner side of the crushing roller group. During the process of the motor driving its output shaft to rotate, it can drive the crushing roller group to rotate synchronously, so as to realize the crushing treatment of the sundries in the sewage, break the relatively large sundries into small pieces, so as to facilitate the subsequent treatment of the sundries by the main body of the decontamination machine. During the crushing process, if the strip-shaped sundries are still wound around the periphery of the crushing roller group, as the winding time increases, the force of the strip-shaped sundries wound around the periphery of the crushing roller group becomes tighter and tighter. At the same time, each crushing strip can be continuously extruded towards the inside of the crushing roller group, and the connecting block drives the extrusion block. By setting the surface of the extrusion block close to the connecting block as an inclined surface, the extrusion block can be extruded, so that the extrusion block moves along the chute opened inside the crushing roller group following the fixed block. And by setting the surface of the extrusion block close to the pushing block as an inclined surface, the extrusion block can be extruded, and the cutter is driven to move towards the outside of the crushing roller group, so that the length of the cutter extending out of the periphery of the crushing roller group is greater than the length of the crushing strip on the periphery of the crushing roller group. At the same time, the cutter can be in contact with and extrude the strip-shaped sundries, so as to cut off the strip-shaped sundries, so that the sundries are separated from the periphery of the crushing roller group, avoiding the sundries continuing to wind around the periphery of the crushing roller group and affecting the crushing effect of the crushing roller group on other sundries. After the sundries are separated from the periphery of the crushing roller group, the crushing strip can be automatically extruded towards the outside of the crushing roller group by installing the second spring, and the cutter can be automatically pulled towards the inside of the crushing roller group by installing the first spring, so as to continue to use the crushing strip to crush other sundries; and by setting the adjusting component, the positions of the crushing strip and the cutter can be moved and adjusted at the same time. During the process of the crushing strip moving towards the inside, the cutter can be extruded towards the outside, so that the crushing strip and the cutter can move in the opposite direction, thus facilitating the alternation of crushing and cutting work.

[0009] A further improvement of the technical solution of the present invention lies in that: the outer surface of each crushing strip is set to an arc shape.

[0010] Adopting the above technical solution, in this solution, by setting the outer surface of the crushing strip to an arc shape, the smoothness of the outer surface of the crushing strip can be improved compared with the rectangular crushing strip, and to a certain extent, it can prevent the strip-shaped sundries from getting stuck on the surface of the crushing strip and winding around the periphery of the crushing roller group.

[0011] A further improvement of the technical solution of the present invention lies in that: a pair of fixed blocks are fixedly installed on the top of each pushing block, and a chute matching the shape of each fixed block is opened inside the crushing roller group, and each fixed block is slidably connected with each chute respectively.

[0012] By adopting the above technical solution, in this solution, the sliding track of the push block inside the crushing roller group can be guided and limited by installing the fixed block, ensuring that the push block can maintain linear movement, thereby ensuring that the push block can squeeze the squeezing block.

[0013] A further improvement of the technical solution of the present invention is that a pair of separation rollers are arranged at one end of the crushing roller group, a connecting frame is fixedly installed at one end of each fixing frame, each connecting frame is rotatably connected to the top and bottom of each separation roller, and a plurality of protrusions are arranged on the periphery of the separation roller.

[0014] The above technical solution is adopted. In this solution, the separation roller is rotatably connected to the connecting frame so that the separation roller can automatically rotate following the flow direction of the water flow. At the same time, a plurality of protrusions are arranged on the periphery of the separation roller so that part of the band-like debris can be pre-wound around the periphery of the separation roller, and the band-like debris can be separated from other debris, thereby preventing the band-like debris from being wound around the periphery of the crushing roller group and affecting the operation of the crushing roller group to a certain extent.

[0015] A further improvement of the technical solution of the present invention is that a scraping disc is slidably mounted on the periphery of each separation roller, and a plurality of grooves are formed on the inner surface of each scraping disc, and each groove and each protrusion are interlocked.

[0016] By adopting the above technical solution, in this solution, by pushing the scraper disc upward, the strip-shaped debris wrapped around the periphery of the separation roller can be moved upward, so that the user can uniformly collect the strip-shaped debris and quickly clean the separation roller.

[0017] A further improvement of the technical solution of the present invention is that a plurality of connecting rods are fixedly installed on the top of each scraper disk outside each separation roller, and a plurality of pull rings are arranged on the top of each separation roller, and each connecting rod extends out of the top of each separation roller and is fixedly connected to the lower surface of each pull ring.

[0018] The above technical solution is adopted. In this solution, the pull ring and the scraper disc can be connected by installing a connecting rod. By pulling the pull ring, the user can move the scraper disc upward, which further facilitates the cleaning of the separation roller and improves work efficiency.

[0019] A further improvement of the technical solution of the present invention is that a guide plate is provided at one end of each separation roller, and each guide plate is inclined toward the outside of one end.

[0020] With the above technical solution, in this solution, by setting the two guiding plates to be inclined to both sides respectively, it is convenient to guide the sundries in the sewage between the two guiding plates, so that the sundries can pass between the two separating rollers, and finally ensure that the crushing roller group can normally crush the sundries, ensuring the normal operation of the device.

[0021] The beneficial effects of the present invention are as follows:

[0022] 1. The present invention provides a grille decontaminator with a crushing device. Through the mutual cooperation between components, if the strip-shaped sundries continuously wind around the periphery of the crushing roller group, the winding force will become tighter and tighter, continuously squeezing the crushing bars into the interior of the crushing roller group, driving the connecting block to squeeze the pushing block, so that the pushing block can squeeze the extrusion block, enabling the cutter to contact the strip-shaped sundries and squeeze the strip-shaped sundries, thereby automatically cutting off the strip-shaped sundries and preventing the sundries from continuing to wind around the periphery of the crushing roller group and affecting the crushing effect of the crushing roller group on other sundries.

[0023] 2. The present invention provides a grille decontaminator with a crushing device. By setting the outer surface of the crushing bar to be arc-shaped, compared with the rectangular-shaped crushing bar, it can improve the smoothness of the outer surface of the crushing bar, and to a certain extent, prevent the strip-shaped sundries from getting stuck on the outer surface of the crushing bar, avoiding affecting the crushing work of the crushing roller group on the sundries.

[0024] 3. The present invention provides a grille decontaminator with a crushing device. By installing the separating rollers, it can pre-wind some strip-shaped sundries around the periphery of the separating rollers, thereby preventing the strip-shaped sundries from winding around the periphery of the crushing roller group and affecting the work of the crushing roller group to a certain extent; by pulling up the scraping disc, the strip-shaped sundries wound around the periphery of the separating rollers can be moved upward, facilitating the user to collect the strip-shaped sundries uniformly, thus improving the work efficiency.

[0035] As Figure 1 , Figure 3 , Figure 4 and Figure 5As shown in the figure, the present invention provides a grille dirt remover with a crushing device, including a dirt remover main body 1; a crushing roller set 3 is arranged at one end of the dirt remover main body 1, and a pair of fixing frames 2 are fixedly installed on both sides of the dirt remover main body 1. Each fixing frame 2 is respectively rotationally connected to the top and bottom of the crushing roller set 3. On one side of the dirt remover main body 1 at the top of the fixing frame 2, a control panel 4 is fixedly connected. At the top of the fixing frame 2 on one side of the dirt remover main body 1, a motor 6 is fixedly installed. The output shaft of the motor 6 extends into the interior of the fixing frame 2 and is fixedly connected to the top end of the crushing roller set 3. A number of crushing bars 11 are arranged on the periphery inside the crushing roller set 3, and each crushing bar 11 extends out of the interior of the crushing roller set 3. A number of cutting knives 9 are arranged inside the crushing roller set 3, and each cutting knife 9 extends out of the interior of the crushing roller set 3, and each cutting knife 9 is arranged in a staggered manner with each crushing bar 11. Inside each cutting knife 9, an adjusting component 10 for moving and adjusting the cutting knife 9 and the crushing bar 11 is arranged. Each adjusting component 10 includes a connecting block 1001, and each connecting block 1001 is fixedly connected to the inner surface of the crushing bar 11. A number of second springs 1101 are fixedly installed inside the crushing roller set 3, and the outer sides of each second spring 1101 are respectively fixedly connected to the inner surfaces of each crushing bar 11, and each second spring 1101 is respectively located at the top and bottom of each connecting block 1001. An extrusion block 1002 is fixedly installed on the inner surface of each cutting knife 9. A number of first springs 1003 are fixedly installed inside the crushing roller set 3, and each first spring 1003 is respectively fixedly connected to the top of each extrusion block 1002. A pushing block 1004 is arranged between each connecting block 1001 and each extrusion block 1002. The surface of each pushing block 1004 close to each connecting block 1001 is arranged in an inclined plane shape, and each inclined plane is in contact with the connecting block 1001. The surface of each extrusion block 1002 close to each pushing block 1004 is arranged in an inclined plane shape, and each inclined plane is in contact with the pushing block 1004. The outer surface of each crushing bar 11 is arranged in an arc shape. A pair of fixing blocks 1005 are fixedly installed on the top of each pushing block 1004. Inside the crushing roller set 3, a chute matching the shape of each fixing block 1005 is opened, and each fixing block 1005 is respectively slidably connected to each chute.

[0036] In this embodiment, when the main body 1 of the decontamination machine is working, it can adsorb the sundries in the sewage from one end and drive the sundries close to the inner side of the crushing roller set 3. During the process of the motor 6 driving its output shaft to rotate, it can drive the crushing roller set 3 to rotate synchronously, so as to realize the crushing treatment of the sundries in the sewage, and crush some of the relatively large sundries into small pieces, which is convenient for subsequent use of the main body 1 of the decontamination machine to process the sundries. During the crushing process, by setting the outer surface of the crushing strip 11 to an arc shape, the smoothness of the outer surface of the crushing strip 11 can be improved compared with the rectangular crushing strip 11, and to a certain extent, it can prevent the strip-shaped sundries from getting stuck on the surface of the crushing strip 11 and winding around the periphery of the crushing roller set 3. If the strip-shaped sundries still wind around the periphery of the crushing roller set 3, as the winding time increases, the winding force of the strip-shaped sundries around the periphery of the crushing roller set 3 becomes tighter and tighter. At the same time, each crushing strip 11 can be continuously squeezed towards the inside of the crushing roller set 3, and the connecting block 1001 can be driven to squeeze the pushing block 1004. By setting the surface of the pushing block 1004 close to the connecting block 1001 to be an inclined surface, the pushing block 1004 can be squeezed, so that the pushing block 1004 moves along the chute opened inside the crushing roller set 3 following the fixed block 1005. And by setting the surface of the extrusion block 1002 close to the pushing block 1004 to be an inclined surface, the extrusion block 1002 can be squeezed, and the cutter 9 can be driven to move towards the outside of the crushing roller set 3, so that the length of the cutter 9 extending out of the periphery of the crushing roller set 3 is greater than the length of the crushing strip 11 on the periphery of the crushing roller set 3. At the same time, the cutter 9 can be made to contact and squeeze the strip-shaped sundries, so as to cut off the strip-shaped sundries, so that the sundries can be separated from the periphery of the crushing roller set 3, avoiding the sundries from continuing to wind around the periphery of the crushing roller set 3 and affecting the crushing effect of the crushing roller set 3 on other sundries. After the sundries are separated from the periphery of the crushing roller set 3, by installing the second spring 1101, the crushing strip 11 can be automatically squeezed towards the outside of the crushing roller set 3, and by installing the first spring 1003, the cutter 9 can be automatically pulled towards the inside of the crushing roller set 3, which is convenient for continuing to use the crushing strip 11 to crush other sundries; by installing the fixed block 1005, the sliding track of the pushing block 1004 inside the crushing roller set 3 can be guided and limited, ensuring that the pushing block 1004 can move in a straight line, and further ensuring that the pushing block 1004 can squeeze the extrusion block 1002.

[0037] Embodiment 2

[0038] As Figure 1 and Figure 6As shown, on the basis of Example 1, the present invention provides a technical solution: preferably, a pair of separation rollers 7 are provided at one end of the crushing roller group 3, a connecting frame 5 is fixedly installed at one end of each fixing frame 2, each connecting frame 5 is rotatably connected to the top and bottom of each separation roller 7, a plurality of protrusions are provided on the periphery of the separation roller 7, a scraping disk 12 is slidably installed on the periphery of each separation roller 7, a plurality of grooves are provided on the inner surface of each scraping disk 12, each groove is engaged with each protrusion, a plurality of connecting rods 1201 are fixedly installed on the top of each scraping disk 12 on the periphery of each separation roller 7, a plurality of pull rings 1202 are provided on the top of each separation roller 7, each connecting rod 1201 extends out of the top of each separation roller 7 and is fixedly connected to the lower surface of each pull ring 1202.

[0039] In this embodiment, the separation roller 7 is rotatably connected to the connecting frame 5 so that the separation roller 7 can automatically rotate following the flow direction of the water flow. At the same time, a plurality of protrusions are provided on the periphery of the separation roller 7 so that part of the band-like debris can be pre-wound around the periphery of the separation roller 7 to separate the band-like debris from other debris, thereby preventing the band-like debris from being wound around the periphery of the crushing roller group 3 and affecting the operation of the crushing roller group 3 to a certain extent. By pushing the scraper plate 12 upward, the band-like debris wrapped around the periphery of the separation roller 7 can be moved upward so that the user can collect the band-like debris uniformly and clean the separation roller 7 quickly. By installing the connecting rod 1201, the pull ring 1202 can be connected to the scraper plate 12. By pulling the pull ring 1202, the user can move the scraper plate 12 upward, which further facilitates the cleaning of the separation roller 7 and improves the work efficiency.

[0040] Example 3

[0041] like Figure 1 As shown, based on Example 2, the present invention provides a technical solution: preferably, a guide plate 8 is provided at one end of each separation roller 7, and each guide plate 8 is inclined toward the outside of one end.

[0042] In this embodiment, the two guide plates 8 are respectively set to be inclined to both sides, so that the debris in the sewage can be guided between the two guide plates 8, so that the debris can pass between the two separation rollers 7, and finally ensure that the crushing roller group 3 can normally crush the debris, ensuring the normal operation of the device.

[0043] The following is a detailed description of the working principle of the grille cleaner with a crushing device.

[0044] like Figures 1-6As shown, after the user finishes installing and fixing the device, the decontamination machine main body 1 and the motor 6 can be turned on. The decontamination machine main body 1 can adsorb sewage and the sundries in the sewage. At the same time, the two guide plates 8 can guide and limit the flow trajectory of the sundries, so that the sundries continuously approach the inside of the crushing roller group 3. At the same time, it can drive the separation roller 7 to rotate along the flow direction of the water flow. If there are strip-shaped sundries in the sundries, part of the strip-shaped sundries can be pre-wound around the periphery of the separation roller 7 to separate the strip-shaped sundries from other sundries, preventing the strip-shaped sundries from winding around the periphery of the crushing roller group 3 and affecting the subsequent crushing work. And the motor 6 is used to drive the crushing roller group 3 to rotate. When the sundries pass through the crushing roller group 3, the crushing roller group 3 can be used to crush the sundries, so as to facilitate the subsequent use of the decontamination machine main body 1 to further remove the sundries. If part of the strip-shaped sundries wind around the periphery of the crushing roller group 3, the strip-shaped sundries continuously rotate with the crushing roller group 3, making the winding force tighter and tighter. It can continuously squeeze the crushing strip 11 into the inside of the crushing roller group 3, and at the same time drive the connecting block 1001 to squeeze the pushing block 1004, and the pushing block 1004 then squeezes the extrusion block 1002, so that the cutter 9 contacts and squeezes the strip-shaped sundries, so as to cut off the strip-shaped sundries, avoiding the sundries from continuing to wind around the periphery of the crushing roller group 3 and affecting the crushing effect of the crushing roller group 3 on other sundries. When the sundries leave the periphery of the crushing roller group 3, the second spring 1101 automatically squeezes the crushing strip 11 out of the crushing roller group 3, and at the same time the first spring 1003 automatically pulls the cutter 9 into the inside of the crushing roller group 3, so as to continue using the crushing strip 11 to crush other sundries; after the device is used, the user can pull up the pull ring 1202 and at the same time dial up the scraping disc 12, so as to move the strip-shaped sundries wound around the periphery of the separation roller 7 upward, facilitating the user to collect the strip-shaped sundries uniformly.

[0045] The above text generally describes the present invention in detail. However, based on the present invention, some modifications or improvements can be made, which are obvious to those of ordinary skill in the technical field. Therefore, the modifications or improvements made without departing from the spirit of the present invention are all within the protection scope of the present invention.
