[0002] Construction sites typically require a large quantity of wood products such as formwork, wedges, and timber. Due to the complexity of construction sites, most wood products need to be processed on-site. Circular saws are commonly used on construction sites because they can easily cut wood into shapes. However, most circular saws on the market lack effective sawdust and sawdust collection capabilities. The sawdust and sawdust generated during cutting are directly scattered on the ground. This not only easily leads to the accumulation of sawdust and dust on the ground, making cleaning difficult, but also hinders civilized construction practices and causes environmental pollution. Furthermore, the blade height of existing circular saws is generally not adjustable, making it difficult to meet the safety requirements for processing wood of different thicknesses. These problems severely restrict the efficiency and quality of wood processing on construction sites.

Detailed Implementation

[0023] The following specific examples illustrate the implementation of this utility model. Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification. This utility model can also be implemented or applied through other different specific embodiments, and various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of this utility model. It should be noted that the illustrations provided in the following embodiments are only for illustrating the basic concept of this utility model. Unless otherwise specified, the following embodiments and features in the embodiments can be combined with each other.

[0024] Please see Figure 1-4 Please see Figure 1-4This embodiment discloses a multifunctional circular saw operating platform, including a support frame 1, an operating plate 2, a circular saw 3, and a sawdust collection mechanism 4. The operating plate 2 is height-adjustable and located at the top of the support frame 1. The operating plate 2 has a saw blade mounting hole 201 in its central area and multiple chip-extraction holes 202 distributed around the saw blade mounting hole 201. The circular saw 3 includes a drive motor 301 mounted on the support frame 1 and a circular saw blade 302 connected to the output end of the drive motor 301. The circular saw blade 302 is located in the saw blade mounting hole 201 and partially protrudes upwards from the top surface of the operating plate 2. The sawdust collection mechanism 4 is located on the support frame 1 and below the operating plate 2, used to collect sawdust falling from the chip-extraction holes 202 and the saw blade mounting hole 201 during the cutting process. It is understood that the height adjustment of the operating plate 2 can be achieved in various ways, such as using a threaded lifting mechanism or a hydraulic lifting device, etc., which are not limited here. The support frame 1 can be welded from steel to ensure load-bearing strength. The sawdust holes 202 can be arranged in a ring array or radial distribution, etc. The hole diameter is designed according to the sawdust particle size to ensure that the sawdust can fall smoothly. The sawdust collection mechanism 4 can be a drawer-type chip box 401 or a funnel-type collection container for easy cleaning. It can be understood that in construction, the saw blade mounting holes 201 are basically rectangular elongated holes, and the width of the saw blade mounting holes 201 is slightly larger than the width of the circular saw blade 302. During the cutting process, a protective cover can be added to the top of the circular saw blade 302 to ensure construction safety. This part is the same as that of existing circular saws used in construction, and will not be described in detail here. The central area of ​​the operating panel 2 refers to the area located near the geometric center of the operating panel 2.

[0025] Therefore, in this technical solution: by setting an adjustable operating plate 2, the exposed height of the circular saw blade 302 can be precisely controlled according to different wood thicknesses, avoiding excessive exposure that could cause cutting safety hazards. Since the exposed height of the circular saw blade 302 can be adjusted directly by adjusting the operating plate 2, it is convenient to use and helps improve the efficiency and quality of timber processing on construction sites. By arranging the saw blade mounting hole 201 in the central area of ​​the operating plate 2 and adding multiple sawdust leakage holes 202 distributed around the saw blade mounting hole 201, it is possible to ensure that all sawdust during the cutting process can automatically fall into the sawdust collection mechanism 4 below, reducing the risk of it falling to the ground and thus maintaining the cleanliness of the working environment. The multifunctional circular saw operating table provided in this embodiment can not only collect sawdust conveniently and effectively, but also meet the processing safety requirements of wood of different thicknesses, thereby improving the efficiency and quality of timber processing on construction sites.

[0026] In this embodiment, the support frame 1 includes a horizontally arranged rectangular frame 101 and four sets of support columns 102 respectively located at the four corners of the rectangular frame 101. The operating plate 2 is height-adjustable and connected to the top of the four sets of support columns 102. Specifically, the rectangular frame 101 is a welded steel square tube structure. The four sets of support columns 102 are preferably made of hollow square steel. A threaded rod is fixed to the top of the support column 102, and the top of the threaded rod passes through the operating plate 2. The operating plate 2 is connected to the top of the threaded rod by two locking nuts. In use, the height of the operating plate 2 can be adjusted by adjusting the height of the locking nuts. Thus, this technical solution constructs a stable spatial support system through the topological optimization design of the rectangular frame 101 and the four corner columns. It can effectively ensure the installation stability of the operating plate 2 and effectively resist the horizontal torque generated by the cutting operation. This solution significantly improves the vibration resistance and structural reliability of the equipment under dynamic cutting conditions.

[0027] In this embodiment, the sawdust collecting mechanism 4 includes: a chip collection box 401 with a top opening and a sawdust guide plate 402 located below the operating plate 2 and arranged at an angle. The chip collection box 401 is supported on the rectangular frame 101, and the vertical downward projection of the lower edge of the sawdust guide plate 402 is located within the top opening area of ​​the chip collection box 401. A drive motor arrangement space 402a is formed between the lower part of the sawdust guide plate 402 and the rectangular frame 101 for accommodating the drive motor 301, and the drive motor 301 is disposed in the drive motor arrangement space 402a. Specifically, the chip collection box 401 is formed by welding metal plates. The angle between the inclined sawdust guide plate 402 and the horizontal plane is preferably 30-45 degrees. This angle range can ensure that the sawdust slides smoothly and avoid the structural height from increasing due to an excessive angle. The height dimension of the drive motor arrangement space is determined according to the shape of the motor. The sawdust guide plate 402 is made of stainless steel plate, and its surface is polished to reduce frictional resistance.

[0028] Therefore, this technical solution achieves dual optimization through structural integration: the inclined sawdust guide plate 402 forms a continuous sliding channel, allowing sawdust to efficiently collect in the chip collection box 401 under gravity. Simultaneously, the unused space below the guide plate is used to house the drive motor 301, effectively improving the overall space utilization of the device. Furthermore, this layout prevents sawdust from accumulating on the motor, ensuring effective heat dissipation and reducing motor failure rates caused by sawdust buildup. Compared to conventional split designs, this integrated structure effectively reduces the overall equipment footprint while maintaining the same functionality, making it particularly suitable for installation and use in confined spaces on construction sites.

[0029] In this embodiment, the sawdust collection mechanism 4 further includes a first side baffle 403 and a first side baffle 404 respectively disposed at both ends of the rectangular frame 101 along the circular saw cutting feed direction; the first side baffle 403 and the first side baffle 404 are arranged in parallel, with both ends of the first side baffle 403 along its length direction respectively attached to and fixed to the corresponding side support column 102, and both ends of the first side baffle 404 along its length direction respectively attached to and fixed to the corresponding side support column 102; the sawdust collection box 401 along the circular saw cutting feed direction has both ends respectively attached to and fixed to the first side baffle 403 and the first side baffle 404; the sawdust guide plate 402 along the circular saw cutting feed direction has both ends respectively attached to and fixed to the first side baffle 403 and the first side baffle 404. Specifically, the first side baffle 403 and the first side baffle 404 are made of steel plate with a thickness of 2-5mm. The tops of the first side baffles 403 and 404 are slightly lower than the top surface of the supporting column 102. The baffles are fixed to the supporting column 102 by bolts, welding, or snap-fit ​​connections. The chip collection box 401 is fitted to the baffle using a sliding plug-in structure, wherein guide grooves are provided on both sides of the chip collection box 401, and matching guide protrusions are provided on the inner side of the baffle. The sawdust guide plate 402 is welded and fixed to the first side baffles 403 and 404 respectively.

[0030] Therefore, this technical solution constructs a closed sawdust collection channel by forming a rigid sidewall structure with double-sided baffles and supporting columns 102, combined with the end-fitting fixation of the chip collection box 401 and sawdust guide plate 402. Specifically, the parallel baffles effectively block the lateral scattering path of sawdust; the tight fit between the chip collection box 401 and the baffles achieves lateral sealing of the collection area; and the fixation of the sawdust guide plate 402 to the baffles ensures that the sawdust slides directionally into the chip collection box 401. The resulting three-in-one closed system ensures that the sawdust must be collected through the predetermined channel of chip leakage hole 202 - sawdust guide plate 402 - chip collection box 401, effectively improving sawdust collection efficiency. This design is particularly suitable for high-frequency cutting operations on construction sites.

[0031] In this embodiment, the rectangular frame 101 has a first base plate 6 laid flat and fixed on the rectangular frame 101 at one end corresponding to the first side baffle 403, and a third side baffle 7 at the end of the first base plate 6 away from the first side baffle 403. A first storage space 10 for placing construction site tools is formed between the first side baffle 403, the first base plate 6, the third side baffle 7, and the sawdust guide plate 402. The rectangular frame 101 has a second base plate 8 laid flat and fixed on the rectangular frame 101 at one end corresponding to the second side baffle 404, and a fourth side baffle 9 at the end of the second base plate 8 away from the second side baffle 404. A second storage space 11 for placing construction site tools is formed between the second side baffle 404, the second base plate 8, the fourth side baffle 9, and the sawdust guide plate 402. Specifically, the first base plate 6 and the second base plate 8 can be fixed to the rectangular frame 101 by welding or bolting, and the steel plate with a thickness of 1.5-3mm is preferably used to ensure load-bearing strength. The third side panel 7 and the fourth side panel 9, together with the first side panel 403 and the second side panel 404, form a closed enclosure structure. The storage space depth is recommended to be controlled within the range of 200-400mm to ensure convenient access to tools.

[0032] Therefore, this technical solution integrates the sawdust collection mechanism 4 with tool storage function through structural reuse. Without increasing the floor space, it forms a closed storage area using a combination of side panels, a bottom plate, and a sawdust guide plate 402. The sawdust guide plate 402, as a shared structural component, serves both as a sawdust guide and as a boundary component of the storage space. This symmetrical storage space design allows commonly used tools such as measuring tapes and wrenches to be categorized and stored on both sides of the saw blade, enabling operators to access tools without leaving the work area. Compared to existing technologies, this solution effectively solves the safety hazards caused by scattered tools, while optimizing space design to avoid increasing the equipment's size and maintain the circular saw's mobility.

[0033] In this embodiment, the chip collection box 401 is slidably inserted between the first side baffle 403 and the first side baffle 404. The sliding insertion structure can be achieved in the following ways: slide rails or protrusions are provided on both sides of the chip collection box 401, cooperating with guide grooves on the inner sides of the first side baffle 403 and the first side baffle 404; or a drawer-type slide rail assembly is used, fixing the slide rail to the side baffle, with the chip collection box 401 connected to the slide rail via a slider; alternatively, rollers can be provided at the bottom of the chip collection box 401, and limiting rails can be provided on the inner side of the side baffle. As a preferred embodiment, a handle or groove can be provided at the front end of the chip collection box 401 for easy pull-out operation.

[0034] Therefore, this technical solution, through the sliding fit between the side baffle and the chip collection box 401, allows the operator to easily retrieve and place sawdust by simply pulling the chip collection box 401 along the guide path formed by the side baffle, without needing to lift the entire device. The side baffle not only limits the range of sawdust splashing but also ensures the stability of the chip collection box 401 during the pulling process through a precise guiding structure. This design significantly reduces the labor intensity of cleaning operations and avoids the problem of sawdust scattering caused by moving the chip collection box 401.

[0035] In this embodiment, a reinforcing beam 1011 is provided in the rectangular frame 101, and a motor support plate 1012 is fixedly mounted on the reinforcing beam 1011. The drive motor 301 is fixedly mounted on the motor support plate 1012, and the output end of the drive motor 301 is arranged towards the end away from the chip box 401. The circular saw also includes a transmission assembly 303, which includes a drive wheel 3031, a vertical support plate 3032, a transmission shaft 3033, a driven wheel, and a transmission belt 3035. The drive wheel 3031 is connected to the drive... The output end of motor 301 is connected to the drive; a vertical support plate 3032 is fixed to the end of motor support plate 1012 facing away from the chip box 401; a drive shaft 3033 is rotatably mounted on the top of vertical support plate 3032, and the drive shaft 3033 extends towards the chip box 401 to the saw blade mounting hole 201, and the circular saw blade 302 is connected to the output end of drive shaft 3033; the driven wheel is connected to the input end of drive shaft 3033; a drive belt 3035 connects drive wheel 3031 and driven wheel 3034. Specifically, here the reinforcing beam 1011 is a rectangular steel pipe welded to rectangular frame 101, and there are two reinforcing beams 1011. Motor support plate 1012 is welded and fixed to the top surface of the two reinforcing beams 1011, and the plate thickness should preferably be 8-12mm steel plate to ensure rigidity. The outward-facing arrangement of the drive motor 301 is specifically manifested in that the motor axis forms a 90° angle with the length direction of the chip collection box 401. The vertical support plate 3032 is preferably made of 10-15mm thick steel plate, and its bottom is welded and fixed to the motor support plate 1012. The drive shaft 3033 passes through the gap between the sawdust guide plate 402 and the operating plate 2, achieving connection with the circular saw blade 302. The diameter ratio of the drive wheel 3031 to the driven wheel 3034 is controlled within the range of 1:1.5-2.5, and the drive belt 3035 can be a V-belt or a synchronous belt.

[0036] Therefore, this technical solution achieves dual optimization through spatial layering design: the combined structure of the reinforcing beam 1011 and the motor support plate 1012 effectively improves the installation rigidity of the drive motor 301, which can effectively suppress displacement caused by cutting vibration; the external layout of the transmission component 303 increases the effective volume of the chip collection box 401, and there is no mechanical interference in the sawdust falling path. Specifically, the motor support plate 1012 directly transmits the load of the drive motor 301 to the reinforcing beam 1011, avoiding frame deformation; the transmission shaft 3033 spans the cantilever structure above the chip collection box 401, and achieves bending moment balance through the bearing seat 3036.

[0037] In this embodiment, a bearing seat 3036 is fixedly mounted on the top of the vertical support plate 3032, and bearings are respectively provided at both ends of the bearing seat 3036. The transmission shaft 3033 is rotatably mounted in the bearings. Specifically, the bearing seat 3036 can be made of cast iron or cast steel, and its internal cavity machining accuracy must meet the concentricity requirements of bearing installation. The bearings are preferably deep groove ball bearings or self-aligning roller bearings, specifically selected according to the rotational speed and load of the transmission shaft 3033. The bearing seat 3036 is fixed to the vertical support plate 3032 by welding or bolting. When welding, the verticality error must be ensured to be no more than 0.1 mm / m.

[0038] Therefore, this technical solution effectively solves the radial runout problem of the drive shaft 3033 through a dual-bearing support structure. The rigid mounting base of the bearing housing 3036 can suppress the vibration generated by high-speed rotation, and the support span formed by the bearings at both ends can significantly improve the bending stiffness of the drive shaft 3033, thus significantly improving the stability of power transmission.

[0039] In this embodiment, the drive wheel 3031, driven wheel, and transmission belt 3035 are all located on the side of the vertical support plate 3032 away from the drive motor 301, and a protective plate 5 covering the drive wheel 3031, driven wheel, and transmission belt 3035 is detachably and fixedly connected to the vertical support plate 3032. Specifically, the protective plate 5 can be made of metal sheet or engineering plastic and can be detachably fixed by bolts, buckles, or quick-clamping mechanisms. As a preferred embodiment, the protective plate 5 is designed with a U-shaped structure, with its top and sides extending downward to form a covering space. Ventilation mesh 501 can be opened on the top and sides of the U-shaped plate to facilitate heat dissipation. Here, mounting flanges are provided on the edges of the vertical support plate 3032, and the protective plate 5 is fixed to the flanges by screws. The coverage area of ​​the protective plate 5 should ensure that it completely covers the running trajectory of the transmission belt 3035, and its inner surface should maintain a safe distance of more than 10mm from the rotating parts.

[0040] Therefore, the protective plate 5 in this technical solution prevents operators from accidentally touching the rotating parts. The detachable design of the protective plate 5 facilitates the tension adjustment and replacement of the transmission belt 3035 without compromising its protective function. Compared with existing technologies, this structure ensures safety while also prioritizing ease of maintenance, solving the problems of workplace injury hazards and dust accumulation caused by the exposed transmission components 303 in traditional circular saws.

[0041] In this embodiment, the protective plate 5 is a U-shaped plate, and the U-shaped plate is provided with multiple ventilation mesh holes 501. In specific implementation, it can be formed by stamping 1.2mm thick galvanized steel plate. The ventilation mesh holes 501 can be designed as a circular hole array with a diameter of 3-8mm, or as a long strip mesh. During installation, the two sides of the U-shaped plate are fixed to the vertical support plate 3032 with bolts, so that the central recessed area maintains a safe distance of 15-25mm from the transmission belt 3035.

[0042] Therefore, this solution achieves dual functions through the coordinated design of geometric shape and hole structure: the zigzag structure forms a three-dimensional enclosed space, completely covering the driving wheel 3031, driven wheel 3034, and transmission belt 3035, effectively preventing the entry of external foreign objects and accidental contact by personnel; the ventilation mesh 501 forms an air convection channel on the surface of the protective plate 5, utilizing the airflow generated during equipment operation to achieve passive heat dissipation. It is especially suitable for the dusty and high-load working environment of construction sites.

[0043] In this embodiment, the operation plate 2 is equipped with an L-shaped positioning plate 12 that can be driven to slide along the cutting feed direction perpendicular to the circular saw and can be locked. The L-shaped positioning plate is used to limit the position of the workpiece during the cutting process. Specifically, the operation plate 2 is provided with a sliding groove hole arranged perpendicular to the cutting feed direction of the circular saw. The bottom plate of the L-shaped positioning plate 12 is slidably disposed in the sliding groove hole. A locking bolt is provided on the L-shaped positioning plate 12. When the locking bolt is loosened, the L-shaped positioning plate 12 can be slid; when tightened, the L-shaped positioning plate 12 can be slid to adjust its position. Thus, with the L-shaped positioning plate 12, during use, one end of the template or timber abuts against the vertical plate of the L-shaped positioning plate 12, which facilitates the guidance and positioning of the template or timber during the cutting process. Moreover, the L-shaped positioning plate 12 in this structure is easy to adjust.

[0044] In this embodiment, the operating plate 2 is provided with a chip baffle 13 extending along the cutting feed direction of the circular saw. The chip baffle 13 is located on the side of the L-shaped positioning plate away from the saw blade mounting hole 201. Specifically, the chip baffle 13 is an L-shaped plate structure, welded and fixed to the operating plate 2. By setting the chip baffle 13 in this structure, the risk of sawdust falling from the surface of the operating plate 2 to the ground can be further reduced.
