The transmission screw is vertically connected to the bottom power output end of the direct drive motor via a coupling, and the support guide rail is vertically installed on the side surface of the support frame near the transmission screw.

[0012] Furthermore, the transmission screw and the support guide rail are parallel to each other, and the moving seat and the support guide rail are connected to each other by a slotted embedded structure, and the moving seat and the transmission screw are connected by a thread.

[0013] Furthermore, the mounting bracket and the support frame are welded together, and the mounting bracket has holes for bolt installation at the four opposite corners of its vertical side surface.

[0014] This utility model provides a directional collection cover for dust from sanding hard silica calcium slabs, which has the following beneficial effects: 1. This utility model, through the structural design of the adjustable arm component, allows for flexible adjustment of the length of the electric telescopic arm within a certain range according to actual needs. This enables the collection hood component to more accurately cover the area where sanding dust from hard calcium silicate slabs is generated, effectively improving dust collection efficiency. The cooperation between the first electric joint and the electric rotary seat allows the collection hood component to rotate and swing at multiple angles, further expanding the collection range. Dust from both horizontal and vertical directions can be effectively collected, enhancing the applicability of the equipment. The connection design between the second electric joint and the fixed angle bracket provides a stable support structure for the entire adjustable arm, ensuring the stability of the collection hood component during adjustment and preventing the dust collection effect from being affected by shaking. At the same time, the connection between the movable seat and the drive component allows the adjustable arm component to move as a whole under the action of the drive component, facilitating switching between different workstations and improving the flexibility and convenience of the equipment. This multi-structure collaborative adjustable arm component greatly enhances the performance and practicality of the directional dust collection hood for sanding dust from hard calcium silicate slabs.

[0015] 2. This utility model, through the structural design of the drive component, utilizes a direct-drive motor as a power source to provide stable and powerful driving force, ensuring precise rotation of the transmission screw. The threaded connection between the transmission screw and the moving seat allows the moving seat to move precisely in a straight line along the axial direction of the transmission screw. This transmission method has the advantages of high transmission accuracy and high transmission efficiency, effectively avoiding problems such as slippage and jamming that may occur in traditional transmission methods.

[0019] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model.

[0020] like Figures 1 to 4As shown, a directional collection hood for sanding dust from hard silica calcium slabs includes a collection hood component 1, an adjusting arm component 2, and a driving component 3. The adjusting arm component 2 is horizontally connected and installed on one side of the collection hood component 1. The driving component 3 is connected and installed at the end of the adjusting arm component 2 away from the collection hood component 1. The adjusting arm component 2 includes an electric telescopic arm 201, a first electric joint 202, an electric rotary seat 203, a second electric joint 204, a fixed bracket 205, and a movable seat 206. The first electric joint 202 is installed at the end of the electric telescopic arm 201 near the collection hood component 1, and the electric rotary seat 203 is installed at the end of the first electric joint 202 away from the electric telescopic arm 201. Furthermore, the driving component 3 is installed at the end of the electric telescopic arm 201 away from the first electric joint 202. The second electric joint 204 is connected to a fixed bracket 205 at the end of the second electric joint 204 away from the electric telescopic arm 201. A movable seat 206 is connected to the side of the fixed bracket 205 near the drive component 3 of the adjusting arm component 2. The electric telescopic arm 201, the first electric joint 202, the electric rotary seat 203, and the second electric joint 204 are integrally structured. Holes for bolt installation are provided at the four opposite corners of the connection between the second electric joint 204 and the fixed bracket 205. Utilizing the length adjustment characteristic of the electric telescopic arm 201, the coverage area of ​​the collection hood component 1 can be flexibly adjusted according to the specific location and dust generation range of the hard silica calcium slab sanding powder generating equipment. When the dust generation point location changes or... When the dust-generating area expands, simply operating the electric telescopic arm 201 to extend or shorten it accordingly allows the collection hood component 1 to quickly and accurately reach the appropriate position, ensuring that dust can be collected in a timely and effective manner, preventing dust from spreading to the surrounding environment and causing pollution. The combined use of the first electric joint 202 and the electric rotary seat 203 provides the collection hood component 1 with multi-angle rotation and swing functions. The first electric joint 202 allows the collection hood component 1 to rotate at a certain angle in the horizontal direction, while the electric rotary seat 203 allows the collection hood component 1 to swing in the vertical direction. Through the synergistic effect of the two, the collection hood component 1 can flexibly adjust its posture in three-dimensional space, ensuring that dust in both the horizontal and vertical directions can be collected comprehensively. This design significantly enhances the equipment's adaptability to different dust-generating conditions, improving the comprehensiveness and efficiency of dust collection. The connection design between the second electric joint 204 and the fixed angle bracket 205 provides a stable support structure for the entire adjusting arm component 2. The second electric joint 204 possesses sufficient strength and rigidity to withstand the weight of the collection hood component 1 and the adjusting arm component 2, as well as various forces generated during adjustment. The fixed angle bracket 205 is firmly connected to the movable seat 206 through holes at four opposite corners, further enhancing the stability of the adjusting arm component 2. During adjustment, even if the collection hood component 1 undergoes various angle adjustments and movements, the adjusting arm component 2 remains stable without swaying or tilting, thus ensuring that the dust collection effect is not affected.The connection between the movable seat 206 and the drive component 3 allows the adjusting arm component 2 to move as a whole under the action of the drive component 3. When switching between different workstations is required, simply start the direct drive motor 303 in the drive component 3. The direct drive motor 303 drives the transmission screw 304 to rotate. Since the movable seat 206 is threadedly connected to the transmission screw 304 and interconnected with the support guide rail 305 using a slotted embedded structure, the movable seat 206 will move precisely in a straight line along the axial direction of the transmission screw 304, thereby moving the entire adjusting arm component 2 and the collection cover component 1 to the designated workstation. This design greatly improves the flexibility and convenience of the equipment, reduces the workload of manual handling and adjustment, and improves work efficiency.

[0021] like Figures 1 to 4As shown, the collecting cover component 1 includes a main cover 101, a connecting seat 102, a docking seat 103, a transmission pipe 104, and an anti-stick coating 105. The connecting seat 102 is located in the middle of the side of the main cover 101 near the adjusting arm component 2, and the docking seat 103 is installed in the middle of the top of the main cover 101. The transmission pipe 104 is vertically connected to the top of the docking seat 103, and the inner surface of the transmission pipe 104 is coated with an anti-stick coating 105. Holes for bolt installation are provided around the bottom edges of the main cover 101. The main cover 101 and the connecting seat 102 are integrally formed. Holes for bolt installation are provided at the four opposite corners of the connecting seat 102 and the electric rotary seat 203. Holes for bolt installation are also provided at the four opposite corners of the docking seat 103. The main cover 101 has four diagonal holes at its top for bolt installation. The transmission pipe 104 and the connecting seat 103 are connected by flanges. The transmission pipe 104 uses a bellows-like structure, with flanges at both ends. The holes around the bottom edge of the main cover 101 allow for easy and quick installation of the main cover 101 securely onto the corresponding position in the hard silica calcium slab sanding powder generating equipment. This ensures that the collection cover component 1 will not shift due to vibration or other factors during equipment operation, guaranteeing stable dust collection. The integrated structure of the main cover 101 and the connecting seat 102 not only enhances the overall structural strength but also improves its ability to withstand dust impacts and the tensile force of the adjusting arm component 2. The structure is not easily damaged during operation and improves sealing, effectively preventing dust leakage from the joint between the two components, thus avoiding dust pollution and resource waste. The perforated structure at the four diagonal corners of the connecting seat 102 and the electric rotary seat 203 facilitates the connection between the collection hood component 1 and the adjusting arm component 2. Bolts are used to fasten the connection through these perforated structures, ensuring its firmness. When the adjusting arm component 2 moves and adjusts the collection hood component 1 at various angles, there will be no loosening, thus ensuring the accuracy and stability of dust collection. The perforated structure at the four diagonal corners of the connecting seat 103 and the four diagonal corners of the top of the main hood 101, as well as the flange structure connecting the transmission pipe 104 and the connecting seat 103, further enhance the connection. This makes the installation and disassembly of the transmission pipe 104 extremely simple. When cleaning, maintenance, or replacement of the transmission pipe 104 is required, simply loosen the bolts at the flange connection to easily remove the transmission pipe 104. The operation is convenient and quick, greatly improving the maintenance efficiency of the equipment. The transmission pipe 104 adopts a bellows pipe structure with flange structures at both ends. The bellows pipe has excellent extensibility and flexibility. When the adjusting arm component 2 moves the collection cover component 1, the transmission pipe 104 can freely expand and contract with the position change of the collection cover component 1, without being damaged by excessive stretching or compression. At the same time, it will not affect the normal transmission of dust in the pipe, ensuring the continuity and stability of the dust collection system. The inner surface of the transmission pipe 104 is coated with an anti-stick coating 105.This effectively prevents dust from adhering to the pipe wall during transmission. Due to the anti-stick coating 105, dust does not easily adhere to the inner surface of the transmission pipe 104 during dust transmission, reducing dust residue and clogging. This allows dust to be transported more smoothly through the transmission pipe 104 to subsequent processing equipment, improving the efficiency and smoothness of dust transmission, reducing the probability of equipment failure, and extending the service life of the equipment.

[0022] like Figures 1 to 4As shown, the driving component 3 includes a support frame 301, mounting brackets 302, a direct drive motor 303, a transmission screw 304, and a support guide rail 305. Two sets of mounting brackets 302 are symmetrically installed on the upper and lower sides of the support frame 301. The direct drive motor 303 is vertically installed on the top of the support frame 301, and the transmission screw 304 is vertically connected to the bottom power output end of the direct drive motor 303 via a coupling. The support guide rail 305 is vertically installed on the side of the support frame 301 closest to the transmission screw 304. The transmission screw 304 and the support guide rail 305 are parallel to each other. The movable seat 206 and the support guide rail 305 are connected by a slotted embedded structure. Furthermore, the movable seat 206 and the transmission screw 305... The components 304 and 305 are connected by threads, while the mounting bracket 302 and the support frame 301 are connected by welding. The mounting bracket 302 has four diagonal holes on its vertical side surface for bolt installation. These holes allow for easy and secure mounting of the drive component 3 onto a suitable base or equipment frame, ensuring its stability during operation and preventing displacement due to vibration or external forces. This provides a fundamental guarantee for the stable operation of the entire hard silica calcium slab sanding dust directional collection hood. The direct drive motor 303, as the power core of the drive component 3, possesses stable and powerful power output characteristics, providing continuous and precise power support for the rotation of the transmission screw 304. After the direct drive motor 303 starts, its power is precisely transmitted to the transmission screw 304 through the coupling, driving the transmission screw 304 to rotate at a uniform and precise speed. The threaded connection design between the transmission screw 304 and the moving seat 206 is the key link for the drive component 3 to achieve linear motion conversion. When the transmission screw 304 rotates, due to the interaction of the threads, the moving seat 206 will move linearly along the axial direction of the transmission screw 304. This transmission method has significant advantages of high transmission accuracy and high transmission efficiency. Compared with traditional transmission methods, it can effectively avoid problems such as slippage and jamming, ensuring that the movement of the moving seat 206 is accurate and error-free. The setting of the support guide rail 305 further enhances the movement of the moving seat 206. To ensure stability, the support rail 305 and the movable seat 206 are connected by a slotted embedded structure. This structure ensures that the movable seat 206 maintains close contact with the support rail 305 during movement, effectively preventing deviation and shaking. Whether starting, running, or stopping, the movable seat 206 moves smoothly along the predetermined trajectory under the guidance of the support rail 305, thus ensuring the stability and accuracy of the entire adjusting arm component 2 during vertical movement. This structural design of the drive component 3 provides reliable power and precise transmission control for the overall operation of the hard silica calcium slab sanding dust directional collection hood, enabling operation in various working scenarios.For example, when the location of the hard silica calcium slab sanding powder generating equipment changes, the dust generation range expands, or it needs to switch between different workstations, the drive component 3 can respond quickly. By precisely controlling the movement of the moving seat 206, it drives the adjusting arm component 2 and the collection hood component 1 to the appropriate position, enabling the equipment to maintain a highly efficient and stable operating state at all times. This effectively improves the efficiency and quality of dust collection and reduces the workload and difficulty of manual operation.

[0023] In summary, as Figures 1 to 4 As shown, when using the directional collection hood for sanding dust of hard silica calcium slabs, first, according to the specific location and dust generation range of the hard silica calcium slab sanding dust generating equipment, the electric telescopic arm 201 in the adjusting arm component 2 is operated to extend or shorten accordingly, so as to adjust the collection hood component 1 to a suitable position to ensure that the dust generation area can be fully covered. At the same time, by utilizing the synergistic effect of the first electric joint 202 and the electric rotary seat 203, the collecting hood component 1 can be flexibly adjusted in the horizontal and vertical directions to adapt to dust generation in different directions and achieve all-round dust collection. During the adjustment process, the stable connection structure between the second electric joint 204 and the fixed angle bracket 205 ensures the overall stability of the adjusting arm component 2, preventing swaying or tilting and ensuring that the dust collection effect is not affected. When switching between different workstations is required, the direct drive motor 303 in the drive component 3 is started. The direct drive motor 303 drives the transmission screw 304 to rotate. Since the moving seat 206 is threadedly connected to the transmission screw 304 and is connected to the support guide rail 305 with a slotted embedded structure, the moving seat 206 will move precisely in a straight line along the axial direction of the transmission screw 304, thereby driving the entire adjusting arm component 2 and the collection cover component 1 to move to the designated workstation. During dust collection, the main hood 101 is securely installed at the corresponding position on the equipment. Its integrated structure enhances structural strength and sealing, preventing dust leakage. The transmission pipe 104 freely expands and contracts with the position of the collection hood component 1, and its inner surface anti-stick coating 105 effectively prevents dust adhesion, ensuring smooth dust transmission to subsequent processing equipment. Through this operation and usage, the directional collection hood for hard silica calcium slab sanding dust can efficiently and stably complete the dust collection work, effectively reducing dust pollution to the surrounding environment and improving the cleanliness and safety of the production environment.
