Description

Technical Field

[0001] The utility model relates to the technical field of sewage pumps, in particular to a cutting device for a sewage pump. Background Art

[0002] The cutting device of the sewage pump is a device specially designed to cut impurities in sewage. The main purpose of this device is to prevent impurities such as long fibers, plastics, paper, tapes, cloth strips, straw, ropes, etc. in the sewage from being entangled on the impeller of the sewage pump, thereby maintaining the efficient operation of the sewage pump;

[0003] The existing patent CN216224677U cutting device shreds the garbage through the cutting mechanism. When the sewage pump works to discharge the sewage, the double-axis motor works, and the main reamer disc can be driven to rotate through the main rotating shaft, thereby driving the main reamer to rotate, and the garbage entering the housing is cut and separated, which can prevent the garbage from accumulating and clogging the sewage pump when the sewage pump is working, thereby affecting the normal use of the sewage pump, thereby improving the sewage pump sewage discharge efficiency, and facilitating the sewage pump to discharge sewage and garbage;

[0004] However, in this patent, the garbage is cut only by rotating the cutter disc driven by a dual-axis motor, which cannot cut harder garbage. Instead, the cutter disc may be damaged. In addition, when the cutter disc directly cuts a large volume of garbage into small pieces, the work efficiency is reduced. Therefore, the utility model proposes a cutting device for a sewage pump. Utility Model Content

[0005] The utility model aims to solve the shortcomings in the prior art and provides a cutting device for a sewage pump.

[0006] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a cutting device for a sewage pump, comprising a cutter body, the cutter body comprising a first processing box and a second processing box, a connecting pipe is fixedly connected between the first processing box and the second processing box, and the first processing box and the second processing box are connected through the connecting pipe;

[0007] One side of the first processing box is fixedly connected with a water outlet pipe, and a first cover plate is arranged on the top of the water outlet pipe. One side of the second processing box is fixedly connected with a water inlet pipe, and a second cover plate is arranged on the top of the second processing box.

[0008] As a preferred embodiment, a first rotating shaft is rotatably connected to the first processing box, a first cutting blade is arranged on the first rotating shaft, a first extrusion block is arranged inside the first processing box, and the first extrusion block and the first rotating shaft are both distributed in a ring shape.

[0009] The beneficial effect of adopting the above-mentioned further scheme is: when sewage enters the first treatment box, due to the structural design of the arc surface of the first cutting blade, the sewage can drive the first cutting blade to rotate. At this time, the garbage in the sewage is cut under the action of the first cutting blade. When encountering garbage that cannot be cut, the first cutting blade drives the garbage to rotate to the first extrusion block. Under the action of the first extrusion block, an extrusion force is generated with the first cutting blade, so that the garbage is torn horizontally.

[0010] As a preferred embodiment, a first movable opening is formed on the first cutting blade, and the width of the first movable opening is greater than the width of the first extrusion block.

[0011] The beneficial effect of adopting the above further scheme is: the first movable opening is displaced with the first extrusion block after contact, so that the garbage is extruded and cut, so that the garbage with higher hardness is torn laterally under the action of the first extrusion block, and the first movable opening can prevent the first cutting blade from getting stuck after contacting the first extrusion block during rotation.

[0012] As a preferred embodiment, the second processing box is rotatably connected to a second rotating shaft, the second rotating shaft is provided with a second cutting blade, the inner wall of the second processing box is provided with a second extrusion block, and the second cutting blade and the second extrusion block are distributed in a ring shape.

[0013] The beneficial effect of adopting the above-mentioned further scheme is: when the pre-treated sewage enters the second treatment box, due to the structural design of the arc surface of the second cutting blade, the sewage can drive the second cutting blade to rotate. At this time, the garbage in the sewage is cut under the action of the second cutting blade. When encountering garbage that cannot be cut, the second cutting blade drives the garbage to rotate to the second extrusion block. Under the action of the second extrusion block, an extrusion force is generated with the second cutting blade, causing the garbage to be torn horizontally.

[0014] As a preferred embodiment, a second movable opening is formed on the second cutting blade, and the width of the second movable opening is greater than the width of the second extrusion block.

[0015] The beneficial effect of adopting the above further scheme is: the second movable opening is displaced with the second extrusion block after contact, so that the garbage is extruded and cut, so that the garbage with higher hardness is torn laterally under the action of the second extrusion block, and the second movable opening can prevent the second cutting blade from getting stuck after contacting the second extrusion block during rotation.

[0016] As a preferred embodiment, the first processing box and the second processing box are both provided with threaded rods, the first cover plate and the second cover plate are both provided with rotating seats, the rotating seats are rotatably connected with a clamping plate, the clamping plate and the threaded rod are clamped with each other, and the threaded rod is threadedly connected with a nut located on the outer side of the clamping plate.

[0017] The beneficial effect of adopting the above further scheme is: by clamping the clamping plate on the threaded rod, the first processing box and the first cover plate and the second processing box and the second cover plate are limited, and the nut is further threaded on the threaded rod to limit the clamping plate to prevent the clamping plate from flipping over during use.

[0018] Compared with the prior art, the advantages and positive effects of the utility model are:

[0019] 1. In the utility model, by setting the second treatment box and the first treatment box, the garbage in the sewage can be graded and treated. First, the sewage enters the interior of the second treatment box through the water inlet pipe. While the sewage drives the second cutting blade, the second cutting blade will cut the garbage and rotate the garbage toward the second extrusion block. Under the action of the second extrusion block, the garbage is torn horizontally and torn into two ends. The torn garbage enters the interior of the first treatment box through the connecting pipe. Under the action of the first cutting blade and the first extrusion block, the garbage is torn into multiple sections to achieve graded treatment. The advantage of this method is that it can not only improve the cutting efficiency, but also increase the service life of the blade.

[0020] 2. In the utility model, the clamping plate is clamped on the threaded rod to limit the first processing box and the first cover plate, as well as the second processing box and the second cover plate. The nut is further threaded on the threaded rod to limit the clamping plate to prevent the clamping plate from flipping during use. Even if the nut is loose and falls off during use, the first processing box and the first cover plate, as well as the second processing box and the second cover plate, can still be limited by the clamping between the clamping plate and the threaded rod, and will not be directly separated, thereby improving the practicality of the device. The design of the detachable structure of the first processing box and the second processing box makes it more convenient to repair the blade later. BRIEF DESCRIPTION OF THE DRAWINGS

When sewage enters the first treatment box 2, due to the structural design of the arc surface of the first cutting blade 25, the sewage can drive the first cutting blade 25 to rotate. At this time, the garbage in the sewage is cut under the action of the first cutting blade 25. When encountering garbage that cannot be cut, the first cutting blade 25 drives the garbage to rotate to the first extrusion block 22. Under the action of the first extrusion block 22, an extrusion force is generated with the first cutting blade 25, so that the garbage is torn horizontally.

[0033] Example 2

[0034] like Figure 1-4 As shown, the first cutting blade 25 is provided with a first movable opening 26, the width of the first movable opening 26 is greater than the width of the first extrusion block 22, and the first movable opening 26 and the first extrusion block 22 are displaced with each other after contacting, so that the garbage is extruded and cut, so that the garbage with higher hardness is torn laterally under the action of the first extrusion block 22, and the first movable opening 26 can prevent the first cutting blade 25 from getting stuck after contacting the first extrusion block 22 during rotation.

[0035] The second treatment box 5 is rotatably connected with a second rotating shaft 53, and a second cutting blade 54 is arranged on the second rotating shaft 53.

At this time, the garbage in the sewage is cut under the action of the second cutting blade 54. When encountering garbage that cannot be cut, the second cutting blade 54 drives the garbage to rotate to the second extrusion block 55. Under the action of the second extrusion block 55, an extrusion force is generated with the second cutting blade 54, so that the garbage is torn horizontally.
