Description

Technical Field

[0001] This application relates to the technical field of grain conveying correction, and in particular to a chain plate type grain conveying correction mechanism. Background Technology

[0002] A chain conveyor is a mechanical device that uses metal or plastic chain plates as the load-bearing surface and is driven by sprockets to continuously transport materials. Its core structure consists of a drive unit, chain plates, chains, sprockets, a frame, and a tensioning device. During operation, the drive unit drives the sprockets to rotate, and the sprockets mesh with the chains, causing the chains to circulate along the track. The chain plates are fixed on the chains and form a continuous conveying plane, thereby achieving stable transmission of various materials. Due to the rigidity and durability of the chain plates, this type of conveyor can adapt to the conveying needs of materials of different shapes, sizes, and weights, including bulk materials such as ores, coal, and grains, as well as block and piece materials such as boxes, packaging materials, and parts. It is especially suitable for scenarios that need to bear large loads or operate under complex conditions, such as assembly lines in heavy industry, sorting systems in logistics warehousing, and cleaning and disinfection processes in food processing.

[0003] When conveying grain using chain conveyors, traditional chain conveyors do not have a limit mechanism, which causes bagged grain to roll off the conveyor and affect the conveying of the bagged grain, thus posing certain drawbacks.

[0004] Therefore, in order to solve the above problems, this application provides a chain plate type grain conveying correction mechanism. Utility Model Content

[0005] The purpose of this invention is to provide a chain plate type grain conveying correction mechanism to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a chain plate type grain conveying correction mechanism, including a support base, a chain plate conveyor mounted on the top of the support base, a fixed box mounted on the bottom of the support base, symmetrically opened grooves at both ends of the top of the fixed box, symmetrically installed slide rails at both ends of the bottom inner side of the fixed box, symmetrically installed sliders at both ends of the top of the slide rails, a connecting plate mounted between the tops of the two slide rails on one side of the slide rails, fixed columns mounted at both ends of the top of the connecting plate and inside the two slide grooves, a support plate mounted on the top of the fixed columns and above the fixed box, a support frame mounted on the top of the support plate, two connecting frames mounted on the outside of the support frame, a limiting plate mounted between one end of the connecting frames, a plurality of limiting grooves equally spaced on the outside of the limiting plate, limiting blocks mounted inside the limiting grooves, and a limiting roller mounted on the bottom of the limiting block at one end outside the limiting groove.

[0007] Preferably, a gear is installed at the center of the bottom inner side of the fixed box, and racks are symmetrically arranged on both sides of the gear. The gear meshes with the two racks. A connecting lug is installed on one end of the outer side of one of the racks. An electric telescopic rod is installed on one end of the bottom inner side of the fixed box, and the movable end of the electric telescopic rod is connected to the outside of the connecting lug.

[0008] Preferably, the top end of each rack is connected to the bottom of the connecting plate, and when the rack moves the connecting plate, the two sliders at the bottom slide synchronously on the slide rail.

[0009] Preferably, the bottom of the support plate is in contact with the top of the fixed box, and when the connecting plate moves, the two fixed columns slide inside the slide groove, synchronously driving the support plate to slide on the fixed box.

[0010] Preferably, the inner wall dimension of the limiting groove is adapted to the outer side dimension of one end of the limiting block, and the inner wall of the limiting groove is slidably connected to one end of the limiting block.

[0011] Preferably, a plurality of fixing brackets are installed at equal intervals on the top of the limiting plate, a limiting rod is installed on the top inner side of the fixing bracket, an elastic element is installed on the outer ring surface of the limiting rod, a fixing plate is installed on the outer ring surface of the limiting rod and below the elastic element, a pull ring is installed at one top end of the limiting rod through the top of the fixing bracket, and a bottom end of the limiting rod extends into the interior of the limiting groove and connects to the interior of the limiting block.

[0012] In summary, this application includes the following beneficial technical effects:

[0013] This chain-plate grain conveyor correction mechanism, when the rack moves horizontally, drives the connecting plate to move synchronously through the connection between the top and the connecting plate. As the connecting plate moves, the sliding of the fixed column within the chute drives the support plate to move horizontally. This, along with the support frame and connecting frame, allows for adjustment of the distance between the two sets of limiting plates. The limiting rollers on the limiting plates are used to correct the grain conveyor chain on the chain conveyor, facilitating the correction and guidance of bagged grain of different sizes. When a limiting roller is damaged and needs replacement, pulling the pull ring upwards moves the limiting rod upwards. The movement of the limiting rod causes the fixed plate to compress the elastic element, and simultaneously, the bottom of the limiting rod is pulled out from the limiting block. At this point, the limiting block can slide freely within the limiting groove for replacement. After replacement, releasing the pull ring allows the fixed plate to move the limiting rod downwards under the elastic force of the elastic element, causing the bottom of the limiting rod to re-engage with the limiting block, thus fixing the position of the limiting block and ensuring the stability of the limiting roller during operation. This mechanism is convenient to operate and highly practical. Attached Figure Description

[0019] The following is in conjunction with the appendix Figure 1 - Figure 4 This application will be described in further detail.

[0020] A chain-plate type grain conveyor correction mechanism, referring to Figure 1 - Figure 4 The system includes a support base 1, a chain conveyor 2 mounted on top of the support base 1, a fixed box 3 mounted on the bottom of the support base 1, symmetrical grooves 4 at both ends of the top of the fixed box 3, symmetrical slide rails 5 mounted on both ends of the bottom inner side of the fixed box 3, symmetrical sliders 6 mounted on both ends of the top of the slide rails 5, a connecting plate 7 mounted between the tops of the two slide rails 5 on one side of the slide rails 5, fixed columns 8 mounted at both ends of the top of the connecting plate 7 and inside the two grooves 4, a support plate 9 mounted on the top of the fixed columns 8 and above the fixed box 3, a support frame 10 mounted on the top of the support plate 9, two connecting frames 11 mounted on the outside of the support frame 10, a limit plate 12 mounted between one end of the connecting frames 11, a plurality of limit grooves 13 equally spaced on the outside of the limit plate 12, a limit block 14 mounted inside the limit groove 13, and a limit roller 15 mounted on the bottom of the limit block 14 at one end outside the limit groove 13.

[0021] Reference Figure 3A gear 16 is installed at the center of the bottom inner side of the fixed box 3. Racks 17 are symmetrically arranged on both sides of the gear 16. The gear 16 meshes with the two racks 17. A connecting ear 18 is installed on one end of the outer side of one rack 17. An electric telescopic rod 19 is installed on one end of the bottom inner side of the fixed box 3. The movable end of the electric telescopic rod 19 is connected to the outside of the connecting ear 18. When the electric telescopic rod 19 extends or retracts, it drives one of the racks 17 to move horizontally through the connecting ear 18. Since the gear 16 meshes with the racks 17 on both sides, the movement of the rack 17 will drive the gear 16 to rotate, thereby driving the other rack 17 to move in the opposite direction, realizing the synchronous reverse movement of the racks 17 on both sides.

[0022] Reference Figure 1 - Figure 3 The top end of rack 17 is connected to the bottom of connecting plate 7. When rack 17 moves connecting plate 7, the two sliders 6 at the bottom slide synchronously on slide rail 5. When rack 17 moves horizontally, it drives connecting plate 7 to move synchronously through the connection between the top and the top. The sliders 6 at the bottom of connecting plate 7 slide along slide rail 5, providing guidance and support for the movement of connecting plate 7, ensuring the smoothness and straightness of the movement of connecting plate 7, and avoiding deviation or jamming. The bottom of support plate 9 is in contact with the top of fixed box 3. When connecting plate 7 moves, the two fixed columns 8 slide synchronously inside the slide groove 4, driving the support plate 9 to move synchronously. Plate 9 slides on the fixed box 3. When the connecting plate 7 moves, the sliding of the fixed column 8 in the slide groove 4 drives the support plate 9 to move horizontally. The bottom of the support plate 9 is in contact with the top of the fixed box 3 to reduce shaking during movement. At the same time, the slide groove 4 restricts the movement range of the fixed column 8 to ensure the stability and directional accuracy of the support plate 9. Thus, the spacing between the two sets of limiting plates 12 can be adjusted through the support frame 10 and the connecting frame 11. The limiting roller 15 on the limiting plate 12 is used to correct the grain conveying chain plate on the chain plate conveyor 2, which is convenient for correcting and guiding bagged grain of different sizes.

[0023] Reference Figure 4The inner wall dimension of the limiting groove 13 is adapted to the outer side dimension of one end of the limiting block 14, and the inner wall of the limiting groove 13 and the outer end of the limiting block 14 are slidably connected. When the limiting roller 15 is damaged and needs to be replaced, the limiting block 14 can be easily removed from the limiting groove 13, replaced with a new limiting block 14 with a intact limiting roller 15, and then slid back into the limiting groove 13 to achieve quick replacement of the limiting roller 15, reduce equipment downtime, and improve production efficiency. Several fixing frames 20 are evenly spaced on the top of the limiting plate 12. A limiting rod 21 is installed on the inner top of the fixing frame 20. An elastic element 22 is installed on the outer ring surface of the limiting rod 21. A fixing plate 24 is installed on the outer ring surface of the limiting rod 21 and below the elastic element 22. One end of the limiting rod 21 extends through to the top of the fixed frame 20 and is fitted with a pull ring 23. The bottom end of the limiting rod 21 extends into the limiting groove 13 and connects to the inside of the limiting block 14. By pulling the pull ring 23 upward, the pull ring 23 drives the limiting rod 21 to move upward. The movement of the limiting rod 21 causes the fixed plate 24 to compress the elastic element 22. At the same time, the bottom of the limiting rod 21 is pulled out from the limiting block 14. At this time, the limiting block 14 can slide freely in the limiting groove 13 for replacement. After replacement, the pull ring 23 is released. Under the elastic force of the elastic element 22, the fixed plate 24 drives the limiting rod 21 to move downward, so that the bottom of the limiting rod 21 is reconnected to the limiting block 14, thereby fixing the position of the limiting block 14 and ensuring the stability of the limiting roller 15 during operation.

[0024] The implementation principle of the chain plate type grain conveying correction mechanism in this application embodiment is as follows: When using the conveyor, the electric telescopic rod 19 is preferably of type LX600. The electric telescopic rod 19 is electrically connected to an external power source through a switch. When the electric telescopic rod 19 is activated by the switch, it drives one of the racks 17 to move horizontally through the connecting lug 18. Since the gear 16 meshes with the racks 17 on both sides, the movement of the rack 17 will drive the gear 16 to rotate, thereby driving the other rack 17 to move in the opposite direction, realizing the synchronous reverse movement of the racks 17 on both sides. When the rack 17 moves horizontally, it drives the connecting plate 7 to move synchronously through the connection between the top and the connecting plate 7. The slider 6 at the bottom of the connecting plate 7 slides along the slide rail 5, providing guidance and support for the movement of the connecting plate 7, ensuring the smoothness and straightness of the movement of the connecting plate 7, and avoiding deviation or jamming. When the connecting plate 7 moves, the sliding of the fixed column 8 in the slide groove 4 drives the support plate 9 to move horizontally. The bottom of the support plate 9 is in contact with the top of the fixed box 3 to reduce the movement process. The swaying in the middle, while the sliding groove 4 restricts the movement range of the fixed column 8, ensures the stability and directional accuracy of the support plate 9 movement, thereby realizing the spacing adjustment of the two sets of limit plates 12 through the support frame 10 and the connecting frame 11. The limit roller 15 on the limit plate 12 is used to correct the grain conveying chain plate on the chain plate conveyor 2, which is convenient for correcting and guiding bagged grain of different sizes. When the limit roller 15 is damaged and needs to be replaced, the pull ring 23 is pulled upward, and the pull ring 23 drives the limit rod 21 to move upward. The movement of the limiting rod 21 causes the fixing plate 24 to compress the elastic element 22. At the same time, the bottom of the limiting rod 21 is pulled out from the limiting block 14. At this time, the limiting block 14 can slide freely in the limiting groove 13 for replacement. After the replacement is completed, the pull ring 23 is released. Under the elastic force of the elastic element 22, the fixing plate 24 drives the limiting rod 21 to move downward, so that the bottom of the limiting rod 21 is reconnected to the limiting block 14, thereby fixing the position of the limiting block 14 and ensuring the stability of the limiting roller 15 during operation. This makes the operation convenient and the practicality better.
