Description

Technical Field

[0001] This invention belongs to the field of conveyor technology, specifically a multi-point unloading disc conveyor. Background Technology

[0002] The multi-point discharge disc conveyor is a conveying device that uses a ring chain to pull a reversible disc and runs continuously within a closed casing. It automatically tilts the disc by using inclined tracks at the discharge points along the line, enabling long-distance, multi-point, fixed-point, non-stop discharge. It is suitable for the closed conveying and distribution of powdery and granular materials.

[0003] In practical use, in order to ensure work efficiency, multi-point unloading disc conveyors all adopt the non-stop unloading method, that is, the unloading operation is completed in a continuous running state; however, when the disc is tilted for unloading, the material will generate sliding friction inside the disc, which will easily lead to the bottom plate and side plate of the disc being worn thin or even worn through after long-term use; and the disc of the existing equipment is not easy to replace quickly, and usually requires the use of special tools to complete the disassembly and assembly, which not only has strong limitations in use, but also reduces the overall performance of the machine.

A positioning spring is disposed inside a positioning cylinder; one end of the positioning spring is fixedly connected to the bottom surface inside the positioning cylinder, and the other end is fixedly connected to the positioning cylinder. A positioning square plate is connected to the end of the positioning cylinder away from the positioning spring; a buffer pad is connected to the side of the positioning square plate near the material tray; the side of the material tray is located on the moving path of the buffer pad.

[0016] Compared with the prior art, the beneficial effects of the present invention are: (1) The fixed connection device uses the automatic reset of the elastic component and the precise insertion of the plug slot to realize the tool-free quick loading and unloading of the material tray, which greatly improves the operation efficiency of the material tray disassembly and assembly and reduces the intensity of manual operation; the compression spring provides a buffer for the insertion of the fixed column and provides assistance for disassembly, while the limit spring ensures the tightness of the fixed plug insertion and avoids the fixed plug from loosening and the fixed column from shifting due to equipment vibration and transmission shaking during material conveying and unloading, ensuring the stability of the connection between the material tray and the rotating square cylinder and preventing the material tray from falling off and the material from spilling; at the same time, the sliding fit design of the fixed column and the rotating square cylinder, as well as the precise alignment of the fixed plug and the fixed slot, ensure the coaxiality and positional accuracy of the material tray installation, providing a structural basis for subsequent precise unloading, and the structure of each component is simple. The equipment features smooth operation, a simple transmission structure, low failure rate, and easy daily maintenance and repair. Multiple retaining slots allow the tray to be installed at different positions or heights to accommodate different material specifications. Furthermore, the assembly position of the tray and rotating cylinder can be flexibly adjusted according to the actual material capacity requirements of the unloading operation, improving the adaptability and flexibility of the fixed components. This allows the multi-point unloading mechanism to handle diverse material conveying and unloading scenarios without the need to replace the tray or adjust other structures, further simplifying the operation process and increasing the equipment's versatility. The tray can be quickly replaced without the need for special tools, reducing the equipment's limitations and improving the overall performance. (2) When disassembling the tray, pull the limit plate by the handle, and the limit slide will slide in the opposite direction on the limit base. The limit spring will be compressed, and the fixed insert will be pulled out from the fixed slot and the rotating square tube, releasing the limit on the fixed square column. At this time, the compression spring in the rotating square tube will release its elastic potential energy and push the fixed square column out from the rotating square tube, so that the tray can be disassembled quickly. When the tray is installed and fixed, the compression spring that was originally in the buffer state cannot be reset. The resulting elastic force acts on the fixed square column, thereby increasing the contact force and friction between the fixed insert and the fixed slot, so as to avoid the fixed insert being dislocated due to non-human factors when fixing the tray, thereby improving the installation effect and use stability of the tray. (3) When the material tray loaded with material moves to the corresponding position of the discharge port with the transmission belt, the rotating square cylinder rotates to drive the material tray to complete the discharge action. The material falls into the matching storage box below through the discharge port. During the discharge process, the energy reduction and anti-motion unit can effectively reduce the impact on the material tray, avoid the material tray from shaking and deviating, and ensure smooth discharge. This structure, through the circulation transmission of the transmission belt and the cooperation of the equally spaced drive base, discharge port and storage box, realizes multi-point accurate discharge on the material conveying path, and the material at each discharge point can accurately fall into the corresponding storage box to complete the classification. The collection system breaks through the limitations of traditional single-point unloading, improving the efficiency of material unloading and collection; the fixed-connection device allows for quick loading and unloading of the material tray without complicated tools, reducing operational intensity and improving the ease of use of the equipment; the energy-saving and anti-vibration unit buffers the impact during unloading, preventing material loss due to tray shaking and spillage, and avoiding wear on equipment parts caused by impact, extending equipment life and reducing maintenance costs; thus, it realizes the integration of material conveying and unloading, eliminating the need for additional transfer steps, simplifying the material handling process, and adapting to the needs of large-scale, multi-station material handling. (4) When the material tray rotates to unload, the rotating arc rods on the positioning horizontal plates on both sides slide within the rotating arc cylinder, so that the arc spring is in a buffer state, which is used to limit and guide the rotation of the material tray to prevent the material tray from becoming unstable; thus improving the stability of the material tray during unloading; at the same time, the energy reduction and anti-motion unit and the limiting and fixing device form a linkage structure, and the material tray is automatically clamped and protected while it is installed and fixed, without the need for additional operation steps, which improves the automation level and ease of operation of the equipment; through the flexible contact of the buffer pad, the axial energy absorption buffer of the positioning spring and the circumferential energy absorption buffer of the arc spring, a multi-level energy reduction and protection structure is formed, which fully offsets various impacts during unloading, greatly reduces the shaking and offset amplitude of the material tray, fundamentally avoids material spillage caused by the shaking of the material tray, and reduces material loss; at the same time, the flexible clamping and elastic buffering method is adopted to avoid hard contact with the material tray, prevent the material tray and clamping parts from being worn due to impact, extend the service life of the parts, improve the use effect of the equipment, and further reduce the limitations of the equipment; (5) The displacement block drives the rotating arc cylinder and rotating arc rod to approach the material tray, causing the positioning horizontal plates on both sides of the material tray to move closer to the side of the material tray. Under the action of the positioning cylinder, positioning column and positioning spring, the positioning horizontal plate drives the positioning square plate to move closer to the side of the material tray, so that the buffer rubber pad on the positioning square plate is in close contact with the side of the material tray, thus completing the flexible clamping and limiting of the material tray. When the material tray is impacted and tends to shake when it is unloading material as the rotating square cylinder rotates, the extrusion pressure of the material tray is first transmitted to the buffer rubber pad, which first performs flexible buffering and resists. Part of the impact force is absorbed, and the remaining impact force is transmitted sequentially to the positioning square plate and the positioning cylinder, causing the positioning cylinder to slide into the positioning cylinder and compress the positioning spring. The positioning spring further absorbs energy and buffers the impact. If the material tray sways circumferentially, the rotating arc rod will slide along the rotating arc cylinder and compress or stretch the arc spring. The elastic force of the arc spring can counteract the impact force of the circumferential sway. At the same time, the clamping components set on both sides form a bidirectional limit, forming a stable clamping force from both sides of the material tray to prevent the material tray from moving radially or circumferentially unexpectedly.

[0019] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0020] Implementation examples, by Figures 1 to 13 The present invention includes a machine body 1; a material tray 2; a multi-point unloading mechanism installed inside the machine body 1 for multi-point unloading during material conveying; the multi-point unloading mechanism includes a partition plate 3 installed inside the machine body 1; a T-shaped base 4 installed on top of the partition plate 3; drive pulleys 5 connected to the T-shaped base 4; two drive pulleys 5 are connected to a transmission belt 6; drive bases 7 are installed on the transmission belt 6; several drive bases 7 are arranged at equal intervals; a drive shaft 8 is installed on the drive bases 7; and a rotating square cylinder 9 is connected to the drive shaft. On shaft 8; a limited stop connecting device is provided on the rotating square cylinder 9 for convenient loading and unloading of the material tray 2 onto the rotating square cylinder 9; an energy reduction and anti-impact unit is provided on the rotating square cylinder 9; the energy reduction and anti-impact unit is used to reduce the impact on the material tray 2 during unloading; a discharge port 12 is provided on the partition plate 3; several discharge ports 12 are arranged equidistantly along the contour of the transmission belt 6; a storage box 13 is installed inside the machine body 1; the storage box 13 is located at the bottom of the partition plate 3; several storage boxes 13 correspond one-to-one with the discharge ports 12, and the quantity and position are matched. The machine body 1 is equipped with a multi-point unloading mechanism to achieve multi-point unloading during material conveying. A partition plate 3 is installed inside the machine body 1, and a T-shaped base 4 on its top is connected to a drive pulley 5. Two drive pulleys 5 work together to drive a transmission belt 6. Several drive bases 7 are equidistantly installed on the transmission belt 6. A drive shaft 8 on the drive base 7 is connected to a rotating square cylinder 9. The material tray 2 is easily loaded and unloaded through a limiting and fixing device on the rotating square cylinder 9, allowing the material tray 2 to move synchronously with the rotating square cylinder 9 and the transmission belt 6 to complete material conveying. When the material tray 2 loaded with material moves with the transmission belt 6 to the corresponding position of the unloading port 12, the rotating square cylinder 9 rotates, driving the material tray 2 to complete the unloading action. The material falls through the unloading port 12 into the matching storage box 13 below. During the unloading process, the energy-reducing and anti-vibration unit effectively reduces the impact on the material tray 2, preventing the material tray 2 from shaking and shifting, ensuring unloading. Stable operation; this structure, through the cyclic transmission of the transmission belt 6 and the cooperation of the equally spaced drive base 7, discharge port 12, and storage box 13, achieves multi-point precise unloading along the material conveying path. Material at each unloading point can accurately fall into the corresponding storage box 13 for classified collection, breaking the limitations of traditional single-point unloading and improving material unloading and collection efficiency. The fixed-connection devices allow for quick loading and unloading of the material tray 2 without complex tools, reducing operational intensity and improving equipment usability. The energy-saving and anti-vibration unit buffers impacts during unloading, preventing material loss due to spillage caused by the shaking of the material tray 2 and avoiding wear on equipment components caused by impacts, extending equipment lifespan and reducing maintenance costs. Thus, it achieves integrated material conveying and unloading, eliminating the need for additional transfer steps, simplifying the material handling process, and adapting to large-scale, multi-station material handling needs.

[0021] The limiting and fixing device in this embodiment includes a limiting base 10 connected to both sides of the rotating square cylinder 9; a fixing column 14 installed on the tray 2; a fixing slot 15 disposed through the fixing column 14; a plurality of fixing slots 15 arranged at equal intervals; the opening of the rotating square cylinder 9 faces the fixing column 14; the opening of the rotating square cylinder 9 is located on the moving path of the fixing column 14, and the two fit together; the fixing column 14 and the rotating square cylinder 9 are slidably engaged; a limiting slide column 16 is connected through the limiting base 10; the limiting slide column 16 is slidably engaged with the limiting base 10; a limiting horizontal plate 17 is fixedly installed on the limiting slide column 16; a handle 18 is connected to the limiting horizontal plate 17 away from the limiting slide column 16; and a limiting circular plate 19 is connected to... A limiting slide post 16 is located away from the limiting horizontal plate 17; a compression spring 20 is installed at one end inside the rotating square tube 9, and the other end is located on the moving path of the fixed square post 14; a limiting spring 21 is sleeved on the limiting slide post 16; one end of the limiting spring 21 is fixedly connected to the limiting circular plate 19, and the other end is fixedly connected to the limiting base 10; a fixing block 22 is installed on the side of the limiting horizontal plate 17 near the fixing slot 15; when the fixing square post 14 on the material tray 2 is inserted into the rotating square tube 9, one of the fixing slots 15 is located on the moving path of the fixing block 22; when the fixing block 22 passes through the rotating square tube 9 and is inserted into the fixing slot 15, the fixing of the fixing square post 14 is achieved, and the installation of the material tray 2 is completed; The limiting and fixing device achieves rapid loading, unloading, and stable connection between the material tray 2 and the rotating square cylinder 9 through the sliding, elastic cooperation, and insertion of various components. When installing the material tray 2, the fixing column 14 slides into the rotating square cylinder 9 through the opening. During the sliding process, the fixing column 14 compresses the compression spring 20 inside the rotating square cylinder 9, putting it in a buffer state to control the speed of the material tray 2 during installation. This prevents excessive speed from impacting components and damaging the material tray 2, thus extending its service life. When the fixing column 14 slides to the preset position, several equidistantly arranged fixing... One of the slots 15 is located on the moving path of the retaining block 22 on the limiting horizontal plate 17. At this time, by releasing the limiting horizontal plate 17 that was originally pulled outward, the limiting spring 21 that was originally in the buffer state is reset, thereby driving the limiting horizontal plate 17 to move at the upper limit of the limiting base 10 through the limiting slide 16, thereby driving the retaining block 22 on the limiting horizontal plate 17 to move and reset, so that it passes through the rotating square tube 9 and is accurately inserted into the corresponding retaining slot 15, thereby achieving axial and radial limiting and fixing of the retaining square column 14, and thus completing the stable installation of the material tray 2 and the rotating square tube 9. When disassembling tray 2, the limit plate 17 is pulled by the handle 18, which causes the limit slide 16 to slide in the opposite direction on the limit base 10. The limit spring 21 is compressed, and the fixing block 22 is pulled out from the fixing slot 15 and the rotating square tube 9, releasing the limitation on the fixing column 14. At this time, the compression spring 20 in the rotating square tube 9 releases its elastic potential energy, pushing the fixing column 14 out of the rotating square tube 9, thus quickly completing the disassembly of tray 2. After tray 2 is installed and fixed, the compression spring 20, which was originally in a buffer state, cannot return to its original state. The resulting elastic force acts on the fixing column 14, thereby increasing the contact force and friction between the fixing block 22 and the fixing slot 15. This prevents the fixing block 22 from dislodging due to non-human factors when fixing tray 2, thus improving the installation effect and usage stability of tray 2. This limiting and fixing device, through the automatic reset of the elastic component and the precise engagement of the insert slot, enables tool-free and rapid loading and unloading of the material tray 2, significantly improving the operational efficiency of tray assembly and disassembly and reducing manual labor intensity. The compression spring 20 provides both cushioning for the insertion of the fixing column 14 and assistance for disassembly, while the limiting spring 21 ensures the tightness of the fixing insert 22, preventing the fixing insert 22 from loosening or the fixing column 14 from shifting due to equipment vibration and transmission shaking during material conveying and unloading. This ensures the stability of the connection between the material tray 2 and the rotating square cylinder 9, preventing the material tray from falling off and material from spilling. At the same time, the sliding fit design of the fixing column 14 and the rotating square cylinder 9, as well as the precise alignment of the fixing insert 22 and the fixing slot 15, ensures the coaxiality and positional accuracy of the material tray installation, providing a structural foundation for subsequent precise unloading. Each component has a simple structure and smooth operation, with no complex transmission structure, resulting in a low failure rate and facilitating daily maintenance and repair. Furthermore, the numerous fixing slots 15 allow the material tray 2 to be installed at different positions or heights to accommodate the loading requirements of materials of different specifications. Simultaneously, the assembly position of the material tray 2 and the rotating square cylinder 9 can be flexibly adjusted according to the actual material capacity requirements of the unloading operation, improving the adaptability and flexibility of the fixing components. This allows the entire multi-point unloading mechanism to handle diverse material conveying and unloading scenarios without the need to replace the material tray or adjust other structures, further simplifying the operation process and enhancing the equipment's versatility. Consequently, the material tray 2 can be quickly replaced during equipment use, without the need for special tools, reducing the limitations of equipment use and improving the overall performance of the machine.

[0022] The energy-reducing and anti-motion unit of this embodiment includes a U-shaped base 11, mounted on a rotating square tube 9; a rotating gear 23, mounted on the U-shaped base 11; a retaining rack 24, connected to a limiting horizontal plate 17; the retaining rack 24 meshing with the rotating gear 23; displacement screws 25, mounted on both sides of the U-shaped base 11; the threads of the two displacement screws 25 facing opposite directions; the displacement screws 25 rotatingly engaging with the rotating gear 23; a displacement block 26, connected to the displacement screws 25; and the displacement screw 25... 5. Threaded engagement with displacement block 26; guide slider 27, mounted on displacement block 26; guide cylinder 28, fixedly connected to U-shaped base 11; guide slider 27 is through-connected to guide cylinder 28, the two slidingly engaged; extension base plate 29, mounted on displacement block 26; bent plate 30 mounted on extension base plate 29; rotating arc cylinder 31, mounted on bent plate 30; rotating arc rod 32, fitted into rotating arc cylinder 31; rotating arc cylinder 31 and rotating arc rod 32... The rod 32 is in sliding engagement; both the rotating arc rod 32 and the rotating arc cylinder 31 are coaxial with the center of the drive shaft 8; an arc spring 33 is disposed inside the rotating arc cylinder 31; one end of the arc spring 33 is fixedly connected to the inner bottom surface of the rotating arc cylinder 31, and the other end is fixedly connected to the rotating arc rod 32; a positioning horizontal plate 34 is installed on the end of the rotating arc rod 32 away from the arc spring 33; two positioning horizontal plates 34 are located on both sides of the material tray 2; a positioning cylinder 35 is installed on the side of the positioning horizontal plate 34 near the material tray 2; the positioning cylinder... A column 36 is fitted into the positioning cylinder 35; the positioning column 36 and the positioning cylinder 35 are slidably fitted; a positioning spring 37 is disposed inside the positioning cylinder 35; one end of the positioning spring 37 is fixedly connected to the bottom surface inside the positioning cylinder 35, and the other end is fixedly connected to the positioning column 36; a positioning square plate 38 is connected to the end of the positioning column 36 away from the positioning spring 37; a buffer pad 39 is connected to the side of the positioning square plate 38 near the material tray 2; the side of the material tray 2 is located on the moving path of the buffer pad 39; The energy-reducing and anti-motion unit works in conjunction with the limiting and fixing devices to automatically clamp, limit, and buffer the material tray 2 as it is installed. During unloading, it effectively counteracts impacts and prevents the material tray 2 from shaking or shifting. The U-shaped base 11 of the energy-reducing and anti-motion unit is mounted on the rotating square cylinder 9. The rotating gear 23 on the U-shaped base 11 meshes with the retaining rack 24 on the limiting horizontal plate 17. When the limiting horizontal plate 17 moves towards the retaining square column 14 under the action of the limiting spring 21 to fix the material tray 2, the retaining rack 24 moves synchronously and drives the rotating gear 23 to rotate. The rotating gear 23 then drives the displacement screws 25 on both sides of the U-shaped base 11, whose threads face opposite directions, to rotate synchronously. 5. The threaded displacement block 26 moves towards each other along the displacement screw 25 under the sliding guidance of the guide slider 27 and the guide cylinder 28, driving the extension base plate 29, the bending plate 30 and the subsequent clamping components to move towards the material tray 2 simultaneously; the displacement block 26 drives the rotating arc cylinder 31 and the rotating arc rod 32 to move closer to the material tray 2, so that the positioning horizontal plates 34 located on both sides of the material tray 2 move closer to the side of the material tray 2, so that the positioning horizontal plates 34 drive the positioning square plate 38 to move under the action of the positioning cylinder 35, the positioning cylinder 36 and the positioning spring 37, so that it moves closer to the side of the material tray 2, so that the buffer rubber pad 39 on the positioning square plate 38 is in close contact with the side of the material tray 2, completing the flexible clamping and limiting of the material tray 2; When the material tray 2 is impacted and tends to shake as it rotates with the rotating square cylinder 9 to unload material, the squeezing force of the material tray 2 is first transmitted to the buffer pad 39. The pad provides flexible buffering to offset part of the impact force. The remaining impact force is transmitted to the positioning square plate 38 and the positioning cylinder 36 in sequence, causing the positioning cylinder 36 to slide into the positioning cylinder 35 and compress the positioning spring 37. The positioning spring 37 further absorbs energy and buffers the impact elastically. If the material tray 2 shakes circumferentially, the rotating arc rod 32 will slide along the rotating arc cylinder 31 and compress or stretch the arc spring 33. The elastic force of the arc spring 33 can offset the impact force of the circumferential shaking. At the same time, the clamping components set on both sides form a bidirectional limit, forming a stable clamping force from both sides of the material tray 2 to prevent the material tray 2 from moving radially or circumferentially unexpectedly. When the material tray 2 rotates to unload material, the rotating arc rods 32 on the positioning horizontal plates 34 on both sides slide within the rotating arc cylinder 31, keeping the arc spring 33 in a buffer state. This limits and guides the rotation of the material tray 2, preventing instability and improving its stability during unloading. Simultaneously, this energy-reducing and anti-motion unit forms a linkage structure with the limiting and fixing devices, automatically completing clamping and protection while the material tray 2 is installed and fixed, requiring no additional steps and improving the automation and ease of operation of the equipment. The flexible contact of the buffer pad 39 further enhances the stability. The axial energy-absorbing buffer of the positioning spring 37 and the circumferential energy-absorbing buffer of the arc spring 33 form a multi-level energy-reducing protection structure, which comprehensively offsets various impacts during unloading, greatly reduces the swaying and offset of the material tray 2, fundamentally avoids material spillage caused by the swaying of the material tray, and reduces material loss; at the same time, the use of flexible clamping and elastic buffering avoids hard contact with the material tray 2, prevents the material tray 2 and clamping parts from being worn due to impact, extends the service life of the parts, improves the use effect of the equipment, and further reduces the limitations of the equipment in use.
