Description

Technical Field

[0001] This invention relates to the field of cement molding product manufacturing and processing technology, specifically to a manufacturing and processing equipment for building energy-saving and heat-insulating precast cement pipes. Background Technology

[0002] Energy-saving and heat-insulating precast cement pipes are cement pipes manufactured through a prefabrication process. They typically contain built-in insulation materials (such as polyurethane, rock wool, or aerogel) and are used in heating and cooling precast cement pipe systems in buildings and municipal engineering projects. They combine structural strength with thermal insulation performance, reducing energy consumption.

[0003] At construction and installation sites, precast concrete pipes often need to be cut, fabricated, and reprocessed to match the length, width, and layout of the work site. However, traditional precast concrete pipe cutting and processing equipment is either bulky and inconvenient to carry, or simple in structure and limited in function. Portable cutting and fabrication machines are often used at precast concrete pipe installation sites. These machines have the advantages of simple structure, portability, and low cost; however, their disadvantages include an exposed cutting and fabrication process, high noise levels, and the generation of large amounts of dust during the cutting and processing of precast concrete pipes. Inhaling this dust can cause lung inflammation. Therefore, how to efficiently and comprehensively solve the problem of improving the portability of precast concrete pipe cutting and processing machines while simultaneously avoiding noise and excessive dust concentrations that could affect environmental health and enhance safety is one of the urgent issues that need to be addressed in the current precast concrete pipe cutting and processing industry.

[0004] Further analysis reveals that at construction and installation sites, precast concrete pipes often require beveling to improve connection stability and lifespan. For example, in flange connections, this facilitates insertion of the precast concrete pipe into the socket or flange, preventing damage to the sealing ring from right-angle cuts. Generally, V-shaped or U-shaped beveling is required. However, traditional methods involve manual marking, fixing, and finally cutting. This approach is time-consuming, labor-intensive, and poses significant safety hazards. Furthermore, manual operation results in inaccurate angle control during beveling, leading to numerous burrs or sharp points that require further manual cleaning to prevent scratches. At the same time, whether the precast cement pipe is cut straight or obliquely, the quality protection of the cut is of paramount importance. Generally speaking, both the cut and the pipe body need to be sprayed with a waterproof and moisture-proof coating to improve the service life of the precast cement pipe. Therefore, in addition to the burr removal mentioned above, automated and standardized cutting processing, reducing subsequent operation steps and troubles, and integrated time-saving and labor-saving waterproof protection are also issues that urgently need to be considered. Summary of the Invention

[0005] To address the shortcomings and deficiencies of existing precast cement pipe cutting and manufacturing structures, this invention provides a building energy-saving and thermal insulation precast cement pipe manufacturing and processing equipment with an optimized spatial structure, an integrated design that is easy to carry and move, and improved freedom of cutting angles and processing efficiency.

Finally, it provides effective fixing and support points on both sides of the precast pipe cuts, preventing the problem of cut deformation caused by bending during the cutting of longer precast pipes. One of the key innovations of this invention lies in the optimized and upgraded storage space. While ensuring the storage of components, the use of foam boards to store the soundproofing panels and cover structures ensures neat and organized storage. At the same time, the assembly of the soundproofing panel structure is simple and provides enhanced protection.

[0020] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0021] It should be noted that, in specific embodiments of the present invention, relational terms such as "first" and "second" are used merely to distinguish one entity or operation from another, and do not necessarily require or imply any actual relationship or order between these entities or operations. Furthermore, terms such as "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitations, the use of phrases such as "comprising one" to define an element does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes said element.

[0022] In the description of this invention, unless otherwise explicitly specified and limited, the terms "installed," "connected," "linked," and "equipped" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; or they can refer to the internal connection of two components. Those skilled in the art will understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0023] Example 1: As Figures 1 to 8 As shown: A precast concrete pipe manufacturing and processing equipment for building energy-saving and thermal insulation includes a support mechanism 1, a cutting mechanism 2, a grinding mechanism 3, and a spraying mechanism 4. The support mechanism 1 includes a first base plate 11 and a second base plate 12, which are movably connected by a connector 13 to allow for free switching between an assembled, retractable state and an unfolded, cutting state. In the cutting state, both the first base plate 11 and the second base plate 12 are horizontal and arranged in a straight line; see details below. Figure 2 The structure is shown. In the moving state of this processing equipment, the first base plate 11 and the second base plate 12 are folded together, maintaining surface contact, and can be securely connected via fasteners. See details... Figure 8 As shown.

[0024] like Figures 1-3As shown: In a preferred embodiment, the connector 13 includes a connecting plate 131, a guide rod 132, and a moving wheel 133. The connecting plate 131 is hinged to the first base plate 11 via a hinge 134. One end of the guide rod 132 is fixedly connected to the connecting plate 131, and the other end is installed in a guide groove 135 opened in the second base plate 12. That is, the connecting plate 131 and the second base plate 12 are an integral structure, forming a hinged structure with the first base plate 11 via the hinge 134. Thus, when the first base plate 11 and the second base plate 12 are unfolded, they form a straight line, which is a flat, adjustable-length cement precast pipe manufacturing and processing platform. When the first base plate 11 and the second base plate 12 are folded and connected by snaps to form a surface contact and secure fastening, a combined storage and moving structure similar to a "suitcase" is formed. One of the key innovations of this invention lies in its modular base plate design, which incorporates cavities to house components. Through the hinged connection of the connecting plate 131, guide rod 132, moving wheels 133, and hinge 134, the processing equipment can be freely switched between a modular, mobile state and an unfolded, production / cutting state. While ensuring efficient production and cutting operations and multi-functionality, the ingenious "suitcase" design of the modular structure enhances the equipment's portability, making it easy to carry, time-saving, and labor-saving. It can be widely applied in precast pipe processing scenarios with multiple work sites in construction. All power required in this embodiment is supplied via an external power source.

[0025] like Figure 3 As shown: In a preferred embodiment, the guide rod 132 is further provided with a scale line 136. The purpose of this arrangement is to facilitate the observation and positioning of the moving distance of the second base plate 12 through the scale line 136 of the guide rod 132. The vertical position of the cutting blade on the first base plate 11 is determined, and the vertical position of the baffle 152 on the second base plate 12 is also determined. The baffle 152 serves to limit the movement of one end of the precast cement pipe. Combined with the indication of the scale line 136 on the guide rod 132, the required cutting length for different specifications of precast cement pipes can be clearly known. This optimizes the traditional fixed structure mode, allowing for free adjustment, saving time and effort, and greatly improving the versatility of the processing equipment. Furthermore, the sum of the length of the second base plate 12 and the length of the connecting plate 131 is equal to the length of the first base plate 11. The purpose of this arrangement is to facilitate the formation of a flat column structure in the combined folded storage state, and then, with the cooperation of the moving wheels 133 and the handle 17, push and pull movement, making operation simple and saving time and effort. The movable wheel 133 is mounted on the end of the first base plate 11 via a bracket, such as Figure 2As shown: Rubber support protrusions 16 are provided on the first base plate 11, the connecting plate 131, and the second base plate 12; simultaneously, the height of the moving wheels 133 is consistent with the support protrusions 16, thus achieving horizontality during the cutting process and stability during vertical movement. A handle 17 is also provided on the side of the first base plate 11 away from the moving wheels 133; this design facilitates pulling by the operator. Figure 2 As shown: A fixing hole 137 with a guide groove 135 is also provided on the side wall of the second base plate 12, and a fastening bolt 138 is installed at the fixing hole 137. The purpose of this arrangement is that when the guide rod 132 is adjusted to the required length, the use of the fastening bolt 138 fixes the position of the second base plate 12 and the guide rod 132, thereby ensuring the stability of the precast concrete pipe manufacturing and cutting operation. The first base plate 11 and the connecting plate 131 can also be connected and fastened by a strong magnet 139; the purpose of this arrangement is that when the first base plate 11 and the second base plate 12 are unfolded and flat, the strong magnet 139 provides a strong connection support, ensuring the flatness of the manufacturing and cutting work surface.

[0026] like Figure 1 As shown: In a preferred embodiment, a first cavity 111 and a second cavity 121 are respectively formed in the first base plate 11 and the second base plate 12. This arrangement aims to create storage space for facilitating the storage of parts of the processing equipment, primarily slitting tools and bottled waterproofing agents. In a preferred embodiment, as... Figure 4 As shown: A fastening component 14 is provided on the first base plate 11. The fastening component 14 includes a fastening rod 141, a fastening plate 142, a first electromagnet 143, and a second electromagnet 144. The fastening rod 141 is vertically distributed and can maintain a threaded connection with the first base plate 11; and ensures that the side of the fastening plate 142 is parallel to the cutter 23. The first base plate 11 has holes, and the fastening component 14 as a whole serves as a storage-disassembly unit, connected and installed to the first base plate 11 through the fastening rod 141. There are two fastening plates 142, and one side is hinged. The first electromagnet 143 is disposed on the upper fastening plate 142, and the second electromagnet 144 is disposed on the lower fastening plate 142, ensuring that the first electromagnet 143 and the second electromagnet 144 are matched and installed. Figure 4 As shown, the length of the first electromagnet 143 is greater than the length of the second electromagnet 144, thus adapting to the fixing of precast concrete pipes of different sizes. The fastening plate 142 has an arc-shaped structure, designed to achieve the purpose of fastening precast concrete pipes of different sizes and specifications. The fastening component 14 is located on the left side of the cutter 23, forming a stable support for the left side of the precast concrete pipe.

[0027] like Figure 1 and Figure 2As shown: In a preferred embodiment, a rotating component 15 is provided on the second base plate 12, which can accurately cut and manufacture precast cement pipes of different lengths and diameters. The rotating component 15 includes a support rod 151, a baffle 152, a three-jaw chuck 153, and a rotating motor 154. The support rod 151 is vertically distributed and rotatably mounted on the second base plate 12; specifically, the support rod 151 and the second base plate 12 are connected by a threaded rotation to achieve a fixed position and ensure that the baffle 152 is parallel to the cutter 23. The baffle 152 is circular and is located at the top of the support rod 151; its main purpose is to limit the end of the precast cement pipe, and the precast cement pipe at the position from the right side of the cutter 23 to the baffle 152 is the length required for manufacturing the cut product. The three-jaw chuck 153 is located on one side of the baffle 152. The structure of the three-jaw chuck 153 is existing technology and will not be described in detail. The rotary motor 154 is located on the other side of the baffle 152, and its output shaft is connected to the three-jaw chuck 153. The rotary motor 154 is a servo-controlled motor. This arrangement aims to secure the precast concrete pipe using the three-jaw chuck 153 and limit the end position of the precast concrete pipe using the baffle 152. Furthermore, with the assistance of the rotary motor 154, the precast concrete pipe can be rotated for cutting and polishing, achieving multi-functionality. Simultaneously, effective fixing and support points are provided on both sides of the precast concrete pipe cut, avoiding the problem of cut deformation caused by bending during the cutting of longer precast concrete pipes.

[0028] like Figure 1 and Figure 5As shown: In this embodiment, the slitting mechanism 2 includes a fabrication slitting frame 21, a connecting arm 22, a cutter 23, and a rotary motor 24. The fabrication slitting frame 21 is rotatably mounted on the first base plate 11 to complete the oblique cutting of the precast cement pipe. Specifically, the fabrication slitting frame 21 can be a concave frame structure mainly composed of a crossbeam and side plates. The side plates are hinged to the first base plate 11. The fabrication slitting frame 21 has an overall concave structure and is threadedly connected to the adjustment hole 26 opened in the first base plate 11 through an adjusting rod 25. An tilt sensor 27 is also provided on the fabrication slitting frame 21, specifically, the tilt sensor 27 can be an HMS series IoT tilt sensor 27. An LED display screen 28 is also provided on one side of the first base plate 11, and the LED display screen 28 is signal connected to the tilt sensor 27 for real-time parameter display. The purpose of this arrangement is to fix the position of the fabrication slitting frame 21 by matching the adjusting rod 25 with the adjustment hole 26. Initially, the slitting frame 21 is vertically aligned. When the precast concrete pipe needs to be cut at an angle, the adjusting rod 25 is first loosened, causing the slitting frame 21 to tilt (the angle range for precast concrete pipe cutting is generally 30-45 degrees). The tilt angle is intelligently detected by the tilt sensor 27 and displayed visually on the LED display screen 28. This allows workers to precisely adjust the tilt angle by observing the displayed parameters, improving the cut quality of the precast concrete pipe and avoiding the inaccurate tilt angles caused by manual cutting in existing technologies. The tilt sensor 27 and the LED display screen 28 are connected via a PLC controller; the specific working principle and circuitry are existing technologies and will not be elaborated upon. This section primarily protects the mechanical structure of the cutter 23 for adjusting its tilt angle.

[0029] The connecting arm 22 is vertically distributed on the fabrication and slitting frame 21 and is telescopic. A rotary motor 24 is mounted on the connecting arm 22. In a preferred embodiment, the connecting arm 22 includes an electro-hydraulic telescopic rod 221 and a base 222. One end of the electro-hydraulic telescopic rod 221 is fixedly connected to the fabrication and slitting frame 21, and the other end is connected to the base 222. Specifically, one end of the electro-hydraulic telescopic rod 221 can be fixedly connected to the side wall of the fabrication and slitting frame 21 via a threaded post. This arrangement facilitates disassembly, storage, and installation. The rotary motor 24 is fixedly mounted on the base 222 via a bracket and is a servo-controlled motor. The cutter 23 is mounted on the output shaft of the rotary motor 24. Specifically, the cutter 23 can be installed via a ring sleeve on the output shaft and bolted together. This allows for targeted replacement of the cutter 23 for different specifications, models, and materials of precast cement pipes on-site, enhancing its practicality.

[0030] The specific working principle is as follows: In the initial stage, the cutting frame 21 and the cutter 23 are taken out from the first cavity 111 and positioned and fixed. The operator then turns on the rotary motor 24, which drives the cutter 23 to rotate at high speed. Under the action of the extension of the electric hydraulic telescopic rod 221, the cutter 23 moves downward until the precast concrete pipe is completely cut. This is mainly for cutting precast concrete pipes with smaller diameters. For cutting precast concrete pipes with larger diameters, the rotary motor 24 and the electric hydraulic telescopic rod 221 work together to simultaneously turn on the rotary motor 154 on the second base plate 12 on the right side. This drives the precast concrete pipe to move in a circular motion, achieving efficient cutting of the precast concrete pipe while effectively protecting the cutter 23 and avoiding damage to the cutter 23 caused by the traditional direct cutting method for larger diameter precast concrete pipes. This processing equipment is mainly designed for precast cement pipes with a radius of 10-50cm, which is the main application area for precast pipe construction in building construction.

[0031] like Figure 1 and Figure 6 As shown: In this embodiment, the grinding mechanism 3 includes an electric push rod 31, a base plate 32, a grinding motor 33, and a grinding wheel 34. The electric push rod 31 is located on one side of the fabrication slitting frame 21. Specifically, the electric push rod 31 is a detachable installation structure, which can be connected and installed to the side wall of the fabrication slitting frame 21 via a threaded post. The base plate 32 is located at the other end of the electric push rod 31, and can be fixed by welding. The grinding motor 33 is fixedly installed on the base plate 32 via a bracket, and the grinding wheel 34 is sleeved and installed on the output shaft of the grinding motor 33. The grinding motor 33 is a servo-controlled motor, facilitating subsequent iterative upgrades for automated and intelligent control. Specifically, in the initial state, the electric push rod 31 retracts, and the grinding wheel 34 does not affect the normal operation of the cutter 23. After the precast concrete pipe is manufactured and cut, the electric push rod 31 extends until the grinding wheel 34 contacts the outer wall of the precast concrete pipe end. The grinding wheel 34 is wide enough, and then the grinding motor 33 is activated. The grinding motor 33 drives the grinding wheel 34 to rotate at high speed, completely removing burrs and other imperfections from the end cut, preventing injuries to installation personnel. Next, after grinding is complete, the grinding motor 33 stops, and the electric push rod 31 retracts and resets synchronously.

[0032] like Figure 2 and Figure 7As shown: In this embodiment, the spraying mechanism 4 includes a liquid storage chamber 41, a connecting pipe 42, a telescopic arm 43, a fixing block 44, and a spray pipe 45. The liquid storage chamber 41 is disposed on the first base plate 11, and the liquid storage chamber 41 and the first cavity 111 do not intersect or interfere with each other. The input end of the connecting pipe 42 is connected to the liquid storage chamber 41, and the output end is connected to the spray pipe 45. The length of the connecting pipe 42 is sufficiently long. One end of the telescopic arm 43 is disposed on the side of the fabrication slitting frame 21 away from the grinding wheel 34, and the other end is connected to the fixing block 44; the telescopic arm 43 is preferably a hydraulic telescopic arm 43 structure. Specifically, the grinding wheel 34 is disposed on the front side of the fabrication slitting frame 21, and the spraying mechanism 4 is disposed on the rear side of the fabrication slitting frame 21. The spray pipe 45 is disposed on the fixing block 44. That is, the spray pipe 45 can be moved by the extension and retraction of the telescopic arm 43. In a preferred embodiment, the liquid storage chamber 41 has a liquid inlet 411 on one side of its top end for adding waterproofing agent.

[0033] In this embodiment, a corrosion inhibitor can also be added to the storage chamber to improve the overall corrosion resistance of the precast cement pipe. In a preferred embodiment, a release agent can also be added to form a protective layer on the outer wall of the precast cement pipe, preventing damage caused by long-term exposure to ultraviolet radiation or chemical pollution. In a preferred embodiment, a stirring element 5 is provided within the storage chamber 41. The stirring element 5 includes a stirring rod 51, a stirring motor 52, and stirring blades 53. The stirring rod 51 is vertically distributed and rotatably disposed within the storage chamber 41. The stirring motor 52 is fixedly installed on the first base plate 11, and its output shaft is connected to the stirring rod 51. Multiple stirring blades 53 are evenly distributed on the stirring rod 51. With this arrangement, the stirring motor 52, upon startup, drives the stirring rod 51 and stirring blades 53 to perform stirring motion, improving the fluidity of the waterproofing agent and thus ensuring the continuity and stability of subsequent spraying operations. The liquid storage chamber 41 is also equipped with a liquid pump 46, and an infusion tube 47 is connected to one side of the liquid pump 46. The infusion tube 47 extends outward through the liquid storage chamber 41. The output end of the infusion tube 47 and the input end of the connecting tube 42 can be connected through a pipe valve connector 48. The purpose of this arrangement is to adopt a split connection structure, which is convenient for disassembly, installation and storage. That is, in the folded storage state, there are no debris on the end faces of the first and second plates, which makes it easy to fold and enclose to form a clever design structure similar to a "suitcase", improving its mobility and usability.

[0034] The specific working principle is as follows: After the cut of the precast concrete pipe is ground and reset, the telescopic arm 43 is extended, which drives the spray nozzle 45 to approach the precast concrete pipe. Specifically, a telescopic arm + PLC controller can be used to limit and adjust the travel of the telescopic arm 43 until the spray nozzle 45 is directly opposite the cut of the precast concrete pipe. Next, the liquid pump 46 is started, which drives the flowing waterproofing agent or waterproof and anti-corrosion mixture through the infusion pipe 47 and connecting pipe 42, and finally through the spray nozzle 45 to spray a waterproof and sealing coating on the cut to form a protective layer, thereby improving the safety, quality and lifespan of the precast concrete pipe. Simultaneously, the rotating motor 154 on the second base plate 12 drives the precast concrete pipe to perform a circular motion, which can easily complete the coating operation on the cut.

[0035] One of the key innovations of this invention lies in optimizing the spatial structure design. Using a cutting frame 21 as a foundation, it completes the basic function of cutting and manufacturing precast cement pipes. An optimized grinding structure is placed on one side of the cutting frame 21, automating the grinding of burrs on the precast cement pipe cut edges and avoiding the risk of workers being injured by burrs. Simultaneously, it improves space utilization by incorporating storage for waterproof and anti-corrosion protective liquids and an automated spraying structure, enabling intelligent spraying operations after grinding the precast cement pipe cut edges, effectively improving the quality and lifespan of the cut edges. By combining intelligent tools with a green and public-benefit approach, it achieves an integrated operation of cutting, grinding, and spraying precast cement pipes, avoiding subsequent processing of the cut edges and waterproofing spraying. Furthermore, effective fixing and support points are provided on both sides of the precast cement pipe cut edges, preventing the problem of cut edge deformation caused by bending during the cutting of longer precast cement pipes.

[0036] Example 2: Based on Example 1, as follows Figure 9 and Figure 10 As shown: A precast cement pipe manufacturing and processing equipment for building energy-saving and thermal insulation further includes: a foam board 18 is provided in the second cavity 121, and multiple storage areas 181 are evenly distributed in the foam board 18. Each storage area 181 is fitted with a sound-absorbing board 182; this arrangement facilitates installation, storage, and use, and ensures orderly storage. In a preferred embodiment, the sound-absorbing board 182 mainly consists of a base 183 and sound-absorbing cotton 184 disposed inside the base 183. One side of the sound-absorbing board 182 has a connecting groove 185, and the other side has a connecting post 186; the connecting post 186 of the sound-absorbing board 182 is matched and installed with the connecting groove 185 of the adjacent sound-absorbing board 182 to form a closed structure with end-to-end connection; specifically as follows... Figure 9As shown, the left and right sound-absorbing panels 182 have the same structure, with their connecting grooves 185 and connecting posts 186 both located on the inner side, but in opposite positions. That is, the connecting posts 186 of the left sound-absorbing panel 182 are on the front side, and the connecting posts 186 of the right sound-absorbing panel 182 are on the rear side. The front and rear sound-absorbing panels 182 have the same structure, with their connecting posts 186 and connecting grooves 185 both located on the outer side wall, but in opposite positions. The top and bottom of the sound-absorbing panel 182 also have connecting posts 186, and the first base plate 11 has a connecting groove 185. The connecting posts 186 at the bottom of the sound-absorbing panel 182 are matched and installed with the connecting grooves 185 of the first base plate 11. The top of the sound-absorbing panel 182 is fitted with a cover plate 19, which has the same structure as the sound-absorbing panel 182, that is, it adopts a combination structure of the base 183 and the sound-absorbing cotton 184. The purpose of this design is to enclose and absorb noise in the cement precast pipe manufacturing and cutting process through the soundproof panel 182, thereby improving the comfort and safety of the processing equipment.

[0037] One of the key innovations of this invention lies in the optimized and upgraded storage space. While ensuring the storage of components, the structure of storing the soundproof board 182 and the cover plate 19 using foam board 18 results in neat and organized storage. At the same time, the soundproof board 182 structure is easy to assemble and provides enhanced protection. This achieves an efficient and integrated solution to the complex functions of the manufacturing and cutting machine, effectively reducing the impact of noise and pungent odors generated during manufacturing and cutting, and improving the operational efficiency of safe manufacturing and cutting of precast cement pipes.

[0038] Example 3: Based on Example 2, such as Figure 11As shown: A precast concrete pipe manufacturing and processing equipment for building energy-saving and thermal insulation includes a purification component 6 further provided on the cover plate 19. In a preferred embodiment, the purification component 6 includes a purification chamber 61, a purification package 62, and a fan 63. The purification chamber 61 is opened in the cover plate 19, with an air inlet 64 at the bottom and an air outlet 65 at the top, thus forming a flow structure. The purification package 62 is adapted and installed inside the purification chamber 61, and the outer side of the purification package 62 is composed of air filter cotton to form a packaging structure. The purification body inside the purification package 62 is mainly composed of lemon granules, activated carbon granules, and osmanthus granules. The fan 63 is adapted and installed at the air outlet 65 through a bracket. The specific working principle is that during the HVAC fabrication and cutting process, the combined closed structure of the soundproof plate 182 and the cover plate 19 is first completed. One of the soundproof plates 182 is provided with a transparent observation window structure for easy observation by the staff. The specific operation can be completed through the operation panel with PLC controller set on the first base plate 11, which is simple to operate, saves time and effort, and is safe and automated. Specifically, the blower 63 is started, and it begins high-speed operation, drawing in the dust and pollutants generated during the cutting and sizing of precast cement pipes into the purification chamber 61. There, the dust is filtered and purified by the purification package 62, and then discharged to the outside through the outlet 65. This not only effectively controls dust pollution, preventing a dirty and chaotic construction site, but also achieves quiet processing during the cutting and sizing of precast cement pipes, avoiding disturbance to residents.

[0039] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
