Description

Technical Field

[0001] The utility model relates to the technical field of sewage treatment, and particularly relates to a crushing device for sewage filtration. Background Art

[0002] In areas with frequent rainfall, if the drainage system is not well done, local waterlogging often occurs, resulting in the ground being flooded. Even for a long time after the rainfall ends, if not dealt with in time, the rainwater is still very difficult to handle.

[0003] At present, a relatively effective measure is to provide a sewage collection vehicle to clean up the trapped sewage in time, and then repair the damaged road surface in time to facilitate the travel of vehicles. The existing sewage collection vehicles are mainly equipped with a water tank, a water pump and a filtering device. The water pump absorbs the trapped sewage through a water pipe and sends it to the filtering device for filtration, and then discharges it into the water tank for collection and temporary storage. In order to prevent the blocking of the filtering device, a crushing device is added at the water inlet of the water pump to crush large particles of impurities, so as to facilitate the normal filtration of the subsequent filtering device.

[0004] However, the existing crushing device is easily entangled by flexible substances such as weeds and hair. If it is entangled on the rotating shaft of the crushing device, it is easy to affect the normal use of the crushing device. Summary of the Utility Model

[0005] The purpose of the utility model is to provide a crushing device for sewage filtration to solve the problems in the above background art.

[0031] In addition, the technical features involved in different embodiments of the present utility model described below can be combined with each other as long as they do not conflict with each other.

[0032] Refer to Figures 1 to 5, as a comminuting device for sewage filtration provided by an embodiment of the present utility model, comprises a main body 1, a comminuting assembly 2 and a cutting assembly 3. An inlet 11 is provided on one side of the main body 1, and an outlet 12 is provided on the other side. The comminuting assembly 2 is arranged inside the main body 1 and includes a driving member 21, a driving shaft 22 and comminuting blades 23. The output end of the driving member 21 is fixedly connected to the driving shaft 22, and the comminuting blades 23 are fixed on the side wall of the driving shaft 22. The cutting assembly 3 includes cutting blades 31, a driving pressing member 32 and a reset member. The driving shaft 22 is hollow inside, and a receiving groove 221 communicating with the inside is formed on the side wall of the driving shaft 22. The cutting blades 31 are arranged inside the driving shaft 22 and are slidably connected to the receiving groove 221. The driving pressing member 32 drives the cutting blades 31 to extend out of the receiving groove 221, and the reset member drives the driving pressing member 32 to reset and drives the cutting blades 31 to reset.

[0033] When it is necessary to clean the impurities wound on the driving shaft 22, press the driving pressing member 32. After the driving pressing member 32 acts, it drives the cutting blades 31 to extend out of the receiving groove 221. At the same time of extension, there is a certain impact force, which can cut off the wound weeds, hairs and other impurities. Subsequently, the reset member drives the driving pressing member 32 to reset and drives the cutting blades 31 to reset, facilitating the next cutting action of the cutting blades 31. By adding the cutting assembly 3 in this application, the winding on the driving shaft 22 can be cut in time and made to fall off, facilitating the normal use of the comminuting device.

[0034] Specifically, a sealing chamber 13 and a crushing chamber 14 are provided inside the body 1. The sealing chamber 13 is arranged near the top end of the body 1, and the crushing chamber 14 is arranged near the bottom end of the body 1. The driving member 21 is arranged inside the sealing chamber 13, and the output end of the driving member 21 extends into the crushing chamber 14. The driving shaft 22 is located inside the crushing chamber 14, and the crushing chamber 14 communicates with the water inlet 11 and the water outlet 12. The driving pressing member 32 includes a pressing shaft 321 and a driving connecting rod 322. One end of the pressing shaft 321 is embedded inside the driving shaft 22 and is slidably connected to the driving shaft 22, and the other end passes through the driving member 21 and extends from the sealing chamber 13 to the top end of the body 1. The driving connecting rod 322 is located inside the driving shaft 22 and connects the pressing shaft 321 and the cutting blade 31. The driving connecting rod 322 includes a fixed rod 3221, a first connecting rod 3222, a second connecting rod 3223, a third connecting rod 3224, and a fourth connecting rod 3225. The fixed rod 3221 is fixed inside the driving shaft 22. One end of the first connecting rod 3222 is hinged to the fixed rod 3221, and the other end is hinged to the three-link rod through a pin shaft 3226. One end of the second connecting rod 3223 is hinged to the fixed rod 3221, and the other end is hinged to the four-link rod through a pin shaft 3226. The central positions of the third connecting rod 3224 and the fourth connecting rod 3225 are rotatably connected through a pin 3227, and the pressing shaft 321 is fixedly connected to the pin 3227. The cutting blade 31 includes a blade body 311 and a blade edge 312. A connecting groove 313 is provided on the blade body 311, and the pin shaft 3226 is embedded in the connecting groove 313 and is slidably connected to the connecting groove 313. The fixed rod 3221 hinges and limits one end of the first connecting rod 3222 and the second connecting rod 3223. When the pressing shaft 321 moves, the pressing shaft 321 can drive the pin 3227 to move, thereby realizing the expansion and approach or the expansion and approach of the first connecting rod 3222 and the second connecting rod 3223 or the third connecting rod 3224 and the fourth connecting rod 3225. At this time, the pin shaft 3226 slides in the connecting groove 313. The movement of the pin shaft 3226 can realize the expansion and approach or the expansion and closing of the first connecting rod 3222 and the second connecting rod 3223 or the third connecting rod 3224 and the fourth connecting rod 3225, and further realize the extension and retraction of the cutting blade 31.

[0035] Furthermore, an activity space is left in the connecting groove 313 to facilitate the rotation of the first connecting rod 3222, the second connecting rod 3223, the third connecting rod 3224, and the fourth connecting rod 3225, and prevent the driving connecting rod 322 from abutting and jamming in the connecting groove 313, resulting in the inability of the cutting blade 31 to extend and contract.

[0036] Furthermore, the driving pressing member 32 also includes a pressing block 323. The reset member is a telescopic rod 33. One end of the telescopic rod 33 is fixed to the top of the body 1, and the other end is inserted into the insertion hole 3231 of the pressing block 323. The telescopic rod 33 supports the pressing block 323. The pressing block 323 is provided with a connecting hole 3232. The connecting hole 3232 is provided with a rotating bearing 3233. The other end of the pressing shaft 321 can be inserted into the rotating bearing 3233. The rotating bearing 3233 can eliminate the rotation effect of the pressing shaft 321, so that the pressing block 323 can drive the pressing shaft 321 to move downward, thereby realizing the extending and cutting action of the cutting blade 31.

[0037] Specifically, the diameter of the connecting hole 3232 is larger than the diameter of the pressing shaft 321, so that the side walls of the two do not contact each other. When the telescopic rod 33 is in the extended state, the end of the pressing shaft 321 extends into the connecting hole 3232 and is spaced apart from and does not contact the side wall of the connecting hole 3232. In this case, the connecting hole 3232 has the effect of covering the end of the pressing shaft 321, preventing the operator from accidentally touching the pressing shaft 321 and causing damage. Because the pressing shaft 321 is always rotating when the pulverizing device is in operation, it is prone to certain safety hazards. Therefore, this structural arrangement is adopted. When the pressing block 323 is pressed, the telescopic rod 33 is in a compressed state, the end of the pressing shaft 321 is inserted into the rotating bearing 3233, and the pressing block 323 pushes the pressing shaft 321 to move a certain distance. After the pressing shaft 321 moves, it can drive the pin 3227 to move, thereby realizing the expansion of the first link 3222 and the second link 3223 or the expansion of the third link 3224 and the fourth link 3225, further realizing the extension and cutting of the cutting blade 31.

[0038] Among them, in order to facilitate the pressing of the pressing block 323, the top of the pressing block 323 is set as a plane, and the pressing block 323 can be hit by knocking to press it downward. The cutting blade 31 is instantly extended to cut. After the pressing block 323 loses its pressing effect, it can be driven to move upward under the elongation of the telescopic rod 33. A spring is connected between the pin 3227 and the fixed rod 3221. When the pressing block 323 moves upward, under the action of the restoring force of the spring, the pin 3227 and the pressing shaft 321 move upward at the same time. At this time, the first connecting rod 3222 and the second connecting rod 3223 are brought closer together, or the third connecting rod 3224 and the fourth connecting rod 3225 are brought closer together, further realizing the retraction of the cutting blade 31.

[0039] When the cutting blade 31 in the present application extends out of the storage groove 221, it has a certain impact force, which can cut off impurities such as entangled weeds and hairs. Subsequently, the reset member drives the pressing member 32 to reset and drives the cutting blade 31 to reset, facilitating the next cutting action of the cutting blade 31. Through the additional cutting assembly 3 in the present application, the winding on the drive shaft 22 can be cut in time and made to fall off, facilitating the normal use of the crushing device.

[0040] The embodiments of the specific implementation manners are all preferred embodiments of the present invention, and do not limit the protection scope of the present invention accordingly. Therefore, all equivalent changes made according to the structure, shape, and principle of the present invention should be covered within the protection scope of the present invention.
