Description
Technical Field
[0001] This application relates to the field of conveying devices, and in particular to a grain conveying device for flour processing. Background Technology
[0002] Flour is a staple food in most parts of northern China, and there are many varieties of food made from it, with diverse styles and flavors. The "flour" we usually refer to is wheat flour, which is powder made from milled wheat. In the flour processing, conveyor systems are used to transport the grain raw materials.
[0003] A related technology proposes a grain conveying device, including a mounting bracket, a conveying pipe, and a hydraulic rod. One end of the conveying pipe is rotatably connected to the mounting bracket, and one end of the hydraulic rod is rotatably connected to the mounting bracket and the other end is rotatably connected to the conveying pipe. A screw driven by a motor is installed inside the conveying pipe. One end of the conveying pipe has an inlet hopper, and the other end has a outlet pipe. In operation, material enters the conveying pipe from the inlet hopper, and the rotation of the screw causes the material to rise and exit from the high outlet pipe. The extension and retraction of the hydraulic rod allows for adjustment of the conveying height and angle, adapting to docking with flour processing devices of different heights.
[0004] Regarding the aforementioned technologies, when the height of the flour processing device to be connected is higher than the limit conveying height of the conveying pipe, the connection with the flour processing device cannot be achieved solely through the adjustment of the hydraulic rod, resulting in poor applicability. Utility Model Content
[0005] To address the issue that when the height of the flour processing device to be connected exceeds the limit conveying height of the conveying pipe, the connection cannot be achieved solely through hydraulic rod adjustment, resulting in poor applicability, this application provides a grain conveying device for flour processing.
[0006] The grain conveying device for flour processing provided in this application adopts the following technical solution:
[0007] A grain conveying device for flour processing includes a mounting frame, a fixed frame, a movable frame, and a conveyor belt. The fixed frame is rotatably connected to the mounting frame, and the mounting frame is provided with an angle adjustment mechanism for adjusting the angle of the fixed frame. The movable frame is slidably connected to the fixed frame, and the movable frame is provided with a position adjustment mechanism for adjusting the position of the movable frame. The fixed frame is provided with a first rotating roller, and the movable frame is provided with a second rotating roller at one end away from the fixed frame. A lifting seat is slidably connected vertically to the mounting frame, and a third rotating roller is provided on the lifting seat. The conveyor belt is wound around the first rotating roller, the second rotating roller, and the third rotating roller. The lifting seat is provided with a first rotating motor, and the rotating shaft of the first rotating motor is connected to the third rotating roller.
[0008] By adopting the above technical solution, the first rotating motor drives the third rotating roller to rotate, which in turn drives the conveyor belt wrapped around the first, second, and third rotating rollers to rotate for grain conveying. The fixed frame can rotate under the action of the angle adjustment mechanism, and the movable frame can slide and adjust its position on the fixed frame under the action of the position adjustment mechanism, thereby flexibly adjusting the position of the first and second rotating rollers, and thus changing the conveying angle and conveying distance of the conveyor belt. The lifting seat can slide vertically to adapt to the adjustment of the distance between the first and second rotating rollers, thereby improving the problem that when the height of the flour processing device to be connected is higher than the limit conveying height of the conveying pipe, the connection with the flour processing device cannot be achieved by adjusting the hydraulic rod alone, resulting in poor applicability.
[0009] Optionally, the angle adjustment mechanism includes a sliding seat and a linear drive assembly. A long slot is provided on one side of the fixed frame along its own length direction. The sliding seat is slidably connected to the mounting frame in a transverse direction. A positioning post is provided on the top of the sliding seat. The positioning post is slidably locked in the long slot. The linear drive assembly is used to drive the sliding seat to move.
[0010] By adopting the above technical solution, the linear drive component drives the sliding seat to move laterally on the mounting frame. The positioning column at the top of the sliding seat slides in the long groove of the fixed frame, thereby driving the fixed frame to rotate around the mounting frame, realizing the adjustment of the angle of the fixed frame. In addition, the sliding seat, the fixed frame and the mounting frame form a stable triangular structure, which improves the stability of the fixed frame and thus improves the stability of the grain conveying device of this application.
[0011] Optionally, the linear drive assembly includes a gear, a rack, and a rotating component. The gear is rotatably connected to a sliding seat, the rack is mounted on a mounting bracket along the sliding direction of the sliding seat, the gear meshes with the rack, and the rotating component is mounted on the sliding seat to drive the gear to rotate.
[0012] By adopting the above technical solution, the rotating component drives the gear to rotate. Since the gear meshes with the rack on the mounting frame along the sliding direction of the sliding seat, the gear will move along the rack when it rotates, thereby driving the sliding seat to slide laterally on the mounting frame, realizing the movement of the sliding seat and providing power for adjusting the angle of the fixed frame.
[0013] Optionally, the rotating component includes a worm gear, a worm, and a first servo motor. The first servo motor is mounted on a sliding seat, the worm is mounted on the rotating shaft of the first servo motor, the worm gear is coaxially connected to a gear, and the worm gear meshes with the worm.
[0014] By adopting the above technical solution, the first servo motor drives the worm gear to rotate, the worm gear drives the worm wheel meshing with it to rotate, and the worm wheel drives the coaxially connected gear to rotate. Because the gear meshes with the rack, the sliding seat moves on the mounting bracket, thereby realizing the adjustment of the angle of the fixed bracket. By setting a worm gear transmission between the first servo motor and the gear, a larger transmission ratio can be achieved, making the device structure more compact. At the same time, the worm gear transmission has a self-locking function, which can prevent the gear from rotating in the opposite direction due to external forces, ensuring the stability of the sliding seat position, and thus ensuring the accuracy and reliability of angle adjustment.
[0015] Optionally, the position adjustment mechanism includes a second servo motor and a lead screw. The second servo motor is mounted on the movable frame, and the lead screw is mounted on the rotating shaft of the second servo motor. The lead screw is inserted into the fixed frame along the sliding direction of the movable frame and is threadedly connected to the fixed frame.
[0016] By adopting the above technical solution, the second servo motor drives the lead screw to rotate. Since the lead screw is threadedly connected to the fixed frame, the rotation of the lead screw is converted into the sliding of the movable frame along the fixed frame, thereby adjusting the position of the movable frame on the fixed frame to change the length of grain conveying. The structure is simple and the position adjustment of the movable frame is stable and reliable.
[0017] Optionally, a locking rod is inserted horizontally along the upper edge of the lifting seat, and multiple locking holes are spaced vertically along the upper edge of the mounting bracket, with the locking rod inserted into the locking holes.
[0018] By adopting the above technical solution, when it is necessary to adjust the height of the lifting seat, the locking rod is pulled out from the current locking hole, allowing the lifting seat to slide vertically along the mounting frame. After the lifting seat slides to the appropriate height, the locking rod is inserted horizontally into the corresponding locking hole, thereby locking the position of the lifting seat and ensuring the tension and conveying stability of the conveyor belt.
[0019] Optionally, the conveyor belt is provided with multiple baffles at intervals.
[0020] By adopting the above technical solution and setting multiple baffles at intervals on the conveyor belt, the grain can be prevented from slipping during the conveying process, thereby improving the stability and efficiency of grain conveying.
[0021] In summary, this application includes at least one of the following beneficial technical effects:
[0022] 1. The angle and position adjustment mechanisms can be used to flexibly adjust the angle and length of the conveying device, which improves the problem in the existing technology that when the height of the flour processing device to be connected is higher than the limit conveying height of the conveying pipe, the connection with the flour processing device cannot be achieved by adjusting the hydraulic rod alone, resulting in poor applicability.
[0023] 2. The linear drive assembly drives the sliding seat to move laterally on the mounting frame. The positioning post at the top of the sliding seat slides in the long slot of the fixed frame, thereby driving the fixed frame to rotate around the mounting frame, realizing the adjustment of the angle of the fixed frame. The sliding seat, fixed frame and mounting frame form a stable triangular structure, improving the stability of the grain conveying device of this application.
[0024] 3. The second servo motor drives the lead screw to rotate. Since the lead screw is threadedly connected to the fixed frame, the rotation of the lead screw is converted into the sliding of the movable frame along the fixed frame, thereby adjusting the position of the movable frame on the fixed frame to change the length of grain conveying. The structure is simple and the position adjustment of the movable frame is stable and reliable. Attached Figure Description

[0030] The following is in conjunction with the appendix Figure 1-3 This application will be described in further detail.
[0031] This application discloses a grain conveying device for flour processing. (Refer to...) Figure 1The grain conveying device for flour processing includes a mounting frame 1, a fixed frame 2, a movable frame 3, and a conveyor belt 4. The mounting frame 1 is positioned on the ground and has self-locking casters 11 at its bottom. The fixed frame 2 is rotatably connected to the mounting frame 1 via a rotating shaft and bearings. The mounting frame 1 has an angle adjustment mechanism for adjusting the angle of the fixed frame 2. The movable frame 3 is slidably connected to the fixed frame 2 along its length and has a position adjustment mechanism for adjusting its position. A first roller 21 is rotatably connected to the end of the fixed frame 2 away from the movable frame 3, and a second roller 31 is rotatably connected to the end of the movable frame 3 away from the fixed frame 2. A lifting seat 5 is slidably connected to the mounting frame 1 along the vertical direction. The lifting seat 5 is provided with a locking component for locking the position of the lifting seat 5. A third roller 51 is rotatably connected to the lifting seat 5. A conveyor belt 4 is simultaneously wound around the first roller 21, the second roller 31, and the third roller 51. Multiple baffles 41 are spaced apart on the conveyor belt 4. A first rotating motor 52 is bolted and fixed to the lifting seat 5. The rotating shaft of the first rotating motor 52 is connected to the third roller 51.
[0032] In operation, the first rotating motor 52 drives the third rotating roller 51 to rotate, which in turn drives the conveyor belt 4, which is wound around the first rotating roller 21, the second rotating roller 31, and the third rotating roller 51, to rotate for grain conveying. The fixed frame 2 can rotate under the action of the angle adjustment mechanism to change the conveying angle of the conveyor belt 4. The movable frame 3 can slide and adjust its position on the fixed frame 2 under the action of the position adjustment mechanism, thereby flexibly adjusting the position of the first rotating roller 21 and the second rotating roller 31, and thus changing the conveying distance of the conveyor belt 4. This improves the problem that when the height of the flour processing device to be connected is higher than the limit conveying height of the conveying pipe, it is impossible to achieve docking with the flour processing device by adjusting the hydraulic rod alone, resulting in poor applicability. In addition, the lifting seat 5 can slide vertically to adjust the tension of the conveyor belt 4 to adapt to the adjustment of the distance between the first rotating roller 21 and the second rotating roller 31.
[0033] For example, the angle adjustment mechanism includes a sliding seat 6 and a linear drive assembly. The sliding seat 6 is slidably connected to the mounting frame 1 along the lateral direction. This slidable connection can be achieved through a guide rail and a slider. The guide rail is mounted on the mounting frame 1, and the slider is mounted on the bottom of the sliding seat 6, ensuring smooth sliding of the sliding seat 6 on the mounting frame 1. A positioning post 61 is provided at the top of the sliding seat 6 along the lateral direction. A long groove 22 is provided on one side of the fixed frame 2 along its length. The positioning post 61 is slidably engaged within the long groove 22 of the fixed frame 2. The linear drive assembly is used to drive the sliding seat 6 to move. When the linear drive assembly drives the sliding seat 6 to slide, the positioning post 61 slides within the long groove 22, thereby causing the fixed frame 2 to rotate around its rotational connection point with the mounting frame 1, thus adjusting the angle of the fixed frame 2.
[0034] Specifically, refer to Figure 1 and Figure 2The linear drive assembly includes a gear 62, a rack 63, and a rotating component. The gear 62 is rotatably connected to the sliding seat 6, and the rack 63 is welded and fixed to the mounting bracket 1 along the sliding direction of the sliding seat 6. The gear 62 meshes with the rack 63. The rotating component is located on the sliding seat 6 and is used to drive the gear 62 to rotate. When the rotating component drives the gear 62 to rotate, the sliding seat 6 will slide on the mounting bracket 1 due to the meshing action of the gear 62 and the rack 63, thus fulfilling the functional requirement of the linear drive assembly to drive the sliding seat 6 to move.
[0035] Furthermore, the rotating components include a worm gear 64, a worm 65, and a first servo motor 66. The first servo motor 66 is fixedly mounted on the sliding seat 6. The worm 65 is coaxially connected to the rotating shaft of the first servo motor 66, and the worm gear 64 is coaxially connected to the gear 62, meshing with the worm 65. When the first servo motor 66 starts, its rotating shaft drives the worm 65 to rotate, which in turn drives the worm gear 64 to rotate, which in turn drives the gear 62 to rotate, thereby realizing the movement of the sliding seat 6. The first servo motor 66 can also be replaced by other power devices such as a stepper motor, as long as precise rotation control can be achieved. Through the transmission of the worm gear 64 and worm 65, a larger transmission ratio can be achieved, making the device structure more compact. Simultaneously, the worm gear 64 and worm 65 transmission has a self-locking function, preventing the gear 62 from rotating in the opposite direction due to external forces, ensuring the stability of the sliding seat 6's position, and thus ensuring the accuracy and reliability of angle adjustment.
[0036] For example, refer to Figure 1 The position adjustment mechanism includes a second servo motor 32 and a lead screw 33. The second servo motor 32 is fixedly mounted on the movable frame 3, and the lead screw 33 is coaxially connected to the rotating shaft of the second servo motor 32. The lead screw 33 is inserted into the fixed frame 2 along the sliding direction of the movable frame 3 and is threadedly connected to the fixed frame 2. When the second servo motor 32 is started, its rotating shaft drives the lead screw 33 to rotate. Due to the threaded connection between the lead screw 33 and the fixed frame 2, the movable frame 3 will slide on the fixed frame 2, thereby adjusting the position of the movable frame 3. The position adjustment of the movable frame 3 is driven by the threaded connection between the lead screw 33 and the fixed frame 2, making the movement of the movable frame 3 smooth and reliable, thereby improving the stability of the transmission.
[0037] Reference Figure 3The locking assembly includes a locking rod 7 and a return spring 8. The locking rod 7 is inserted laterally onto the lifting seat 5. Multiple locking holes 12 are spaced vertically along the mounting frame 1, and the locking rod 7 is inserted into each locking hole 12. The return spring 8 is sleeved on the locking rod 7, with one end connected to the locking rod 7 and the other end connected to the lifting seat 5. The return spring 8 tends to tighten the locking rod 7 into the locking hole 12. When the height of the lifting seat 5 needs to be adjusted, the locking rod 7 is pulled out of the current locking hole 12, allowing the lifting seat 5 to slide vertically along the mounting frame 1. After the lifting seat 5 slides to the appropriate height, the return spring 8 laterally inserts the locking rod 7 into the corresponding locking hole 12, thereby locking the position of the lifting seat 5 and ensuring the tension and conveying stability of the conveyor belt 4.
[0038] The implementation principle of the grain conveying device for flour processing in this embodiment is as follows: During use, the material falls onto the conveyor belt 4. The first rotating motor 52 is started to drive the third rotating roller 51 to rotate, thereby driving the conveyor belt 4 to rotate, thus realizing the conveying of the material along the conveyor belt 4. When it is necessary to adjust the conveying angle, it is only necessary to start the first servo motor 66 to drive the worm gear 65 to rotate, drive the worm wheel 64 to rotate, and drive the gear 62 to rotate. Under the meshing action of the gear 62 and the rack 63, the sliding seat 6 is driven to move. The positioning post 61 at the top of the sliding seat 6 slides in the long groove 22 of the fixed frame 2, driving the fixed frame 2 to rotate around the mounting frame 1, thus realizing the adjustment of the angle of the fixed frame 2. When the conveying length needs to be adjusted, simply start the second servo motor 32 to drive the lead screw 33 to rotate. Since the lead screw 33 is threadedly connected to the fixed frame 2, the rotation of the lead screw 33 is converted into the sliding of the movable frame 3 along the fixed frame 2, thereby adjusting the position of the movable frame 3 on the fixed frame 2 and changing the distance between the first roller 21 and the second roller 31, thus adjusting the conveying length. At the same time, the lifting seat 5 moves up and down to adjust the tension of the conveyor belt 4 to adapt to the adjustment of the distance between the first roller 21 and the second roller 31, ensuring the stable conveying function of the conveyor belt 4. This application, through the coordinated arrangement of the position adjustment mechanism, the lifting seat 5, and the locking component, makes the conveying distance of the conveyor belt 4 adjustable, improving the problem that when the height of the flour processing device to be connected is higher than the limit conveying height of the conveying pipe, the connection with the flour processing device cannot be achieved by adjusting the hydraulic rod alone, resulting in poor applicability.
[0039] The above are all optional embodiments of this application and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
