Description

Technical Field

[0001] This utility model relates to the field of connector technology, specifically a connector for a silo. Background Technology

[0002] As a key piece of equipment for storing bulk materials in industrial production, silos often need to be connected to conveying equipment such as screw conveyors to achieve material transfer. Currently, the connection between silos and conveying equipment is mostly achieved by using flanges and bolts and nuts for fixing. That is, flanges are installed at the silo outlet and the conveying equipment inlet, and bolts are inserted after manually aligning the bolt holes on the flanges to complete the fixing.

[0003] However, in actual working conditions, manual docking is easily affected by factors such as shaking of the hoisting equipment and differences in the physical strength of the operators, which can cause the bolt hole axis deviation to exceed 2mm. The equipment position needs to be repeatedly adjusted for calibration. At the same time, if the flange collide during manual lifting, it may cause bolt hole deformation or flange surface damage, further increasing the installation difficulty. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a special connector for silos, which can quickly align the silo body with the flange on the screw conveyor.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a special connector for a silo, comprising a silo body, a screw conveyor installed at the lower end of the silo body, the silo body and the screw conveyor being connected by bolts and nuts to two flanges, flange one and flange two. A mounting block is placed on flange one, a guide rod is mounted on the mounting block, a height adjustment mechanism is fixedly connected to the mounting block, a fixing block is fixedly connected to the height adjustment mechanism, a rotating shaft is fixedly connected to the fixing block, and a pressing mechanism is rotatably connected to the rotating shaft.

[0006] Furthermore, the mounting block has a threaded hole, and the upper end of the guide rod is fixedly connected to a threaded rod that matches the threaded hole.

[0007] Furthermore, the height adjustment mechanism includes a threaded rod two fixedly connected to the mounting block, an internally threaded tube one connected to the threaded rod two, two connecting rods fixedly connected to the internally threaded tube one, an internally threaded tube two fixedly connected to the upper ends of the two connecting rods, a threaded rod three threadedly connected to the internally threaded tube two, and a fixing block fixedly connected to the upper end of the threaded rod three.

[0008] Furthermore, the pressing mechanism includes rotating blocks rotatably connected to both ends of the rotating shaft, and a pressing plate is fixedly connected between the two rotating blocks.

[0009] Furthermore, the mounting block has a groove inside, and a long bolt is rotatably connected to the inner wall of the groove. A slider is threaded onto the long bolt, and the slider is slidably connected to the groove. An arc-shaped plate is fixedly connected to the lower surface of the slider.

[0010] Furthermore, both the surface of the arc-shaped plate and the surface of the extrusion plate are fixedly connected with anti-slip and wear-resistant pads.

[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] This type of silo-specific connector, by setting a mounting block with a guide rod on the flange, together with a height adjustment mechanism and a pressing mechanism, enables rapid alignment and auxiliary fixing of the silo body and the screw conveyor flange, effectively reducing bolt hole alignment time and speeding up the installation process; the guide rod, through the detachable design of threaded rod and threaded hole, can be adapted to the round holes of flanges of different sizes, improving the versatility of the connector.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0018] Please see Figures 1 to 3A special connector for a silo includes a silo body 1, a screw conveyor 2 installed at the lower end of the silo body 1, and the silo body 1 and the screw conveyor 2 are connected by bolts and nuts through two flanges 3 and 4. An mounting block 5 is placed on the flange 3, a guide rod 6 is installed on the mounting block 5, a height adjustment mechanism is fixedly connected to the mounting block 5, a fixing block 7 is fixedly connected to the height adjustment mechanism, a rotating shaft 8 is fixedly connected to the fixing block 7, and a pressing mechanism is rotatably connected to the rotating shaft 8.

[0019] In this utility model, the silo-specific connector is used when the silo body 1 is fixed at a fixed position on the ground and connected to the screw conveyor 2 below it. At this time, it is necessary to connect the flange 4 at the inlet of the screw conveyor 2 to the flange 3 below the outlet of the silo body 1, and secure them together with bolts and nuts. Before this operation, this connector can be installed on the flange 3 below the silo body 1, and at least two connectors should be used. The installation method is as follows: insert the guide rod 6 on the mounting block 5 into a round hole on the flange 3, and ensure that the lower surface of the mounting block 5 is in contact with the surface of the flange 3. Then, adjust the height adjustment mechanism so that the pressing mechanism is flush with the outer wall of the silo body 1. The guide rod 6 is positioned below the flange 3. When the flange 4 moves upward and approaches the guide rod 6, a gap exists between the flange 4 and the flange 3. This gap facilitates the adjustment of the screw conveyor 2, allowing the round hole on the flange 3 to align with the guide rod 6. The flange 4 moves upward along the guide rod 6, thus connecting the flange 4 and the flange 3 together. The round holes on both flanges are aligned, making it easy to directly insert bolts into the round holes and screw in nuts to secure them. This method reduces alignment time and speeds up the installation process of the hopper body 1 and the screw conveyor 2.

[0020] like Figure 3 As shown, the mounting block 5 has a threaded hole 22, and the upper end of the guide rod 6 is fixedly connected to a threaded rod 9 that matches the threaded hole 22.

[0021] Specifically, the guide rod 6 is threaded to the threaded hole 22 via the threaded rod 9, and can be adjusted according to the diameter of the round hole on the flange of different sizes to suit the installation of different models of silo body 1 and screw conveyor 2.

[0022] like Figure 3As shown, the height adjustment mechanism includes a threaded rod 10 fixedly connected to the mounting block 5. The threaded rod 10 is connected to an internally threaded tube 11. Two connecting rods 12 are fixedly connected to the internally threaded tube 11. The upper ends of the two connecting rods 12 are fixedly connected to an internally threaded tube 13. The internally threaded tube 13 is threadedly connected to a threaded rod 14. The fixing block 7 is fixedly connected to the upper end of the threaded rod 14.

[0023] Specifically, after the mounting block 5 is placed, the two connecting rods 12 are rotated so that the first internal thread tube 11 and the second internal thread tube 13 rotate in the same direction at the same time. This causes the first internal thread tube 11 to move upward along the second thread rod 10, and the third thread rod 14 to move upward along the thread direction of the second internal thread tube 13, thereby adjusting the height of the fixing block 7 so that the pressing mechanism is in contact with the outer wall of the hopper body 1.

[0024] like Figure 3 As shown, the pressing mechanism includes rotating blocks 15 rotatably connected to both ends of the rotating shaft 8, and a pressing plate 16 is fixedly connected between the two rotating blocks 15.

[0025] Specifically, as the fixed block 7 and the rotating shaft 8 move upward simultaneously, the extrusion plate 16 also gradually moves upward and comes into contact with the outer wall of the hopper body 1. During the contact process, the tilt angle of the extrusion plate 16 changes with the rotation of the rotating block 15 on the rotating shaft 8, and gradually becomes the same as the tilt angle of the outer wall of the hopper body 1. This allows the extrusion plate 16 to be completely in contact with the outer wall of the hopper body 1 and to stop moving. At this time, the height of the height adjustment mechanism and the tilt angle of the extrusion plate 16 are fixed, so that the mounting block 5 can be supported, extruded and fixed. Thus, when the flange 4 touches the guide rod 6, the guide rod 6 will not move upward.

[0026] like Figure 3 As shown, the mounting block 5 has a sliding groove 17 inside, and a long rod bolt 18 is rotatably connected to the inner wall of the sliding groove 17. A slider 19 is threadedly connected to the long rod bolt 18. The slider 19 is slidably connected to the sliding groove 17, and an arc plate 20 is fixedly connected to the lower surface of the slider 19.

[0027] Specifically, after the mounting block 5 is placed on the flange 3, the long bolt 18 is rotated to move the slider 19 along the direction of the groove 17 until the arc plate 20 is in contact with the outer wall of the flange 3, thereby initially fixing the position of the mounting block 5. This eliminates the need to manually press the mounting block 5 when rotating the two connecting rods 12 on the height adjustment mechanism.

[0028] like Figure 3 As shown, both the surface of the arc plate 20 and the surface of the extrusion plate 16 are fixedly connected with anti-slip and wear-resistant pads 21.

[0029] Specifically, the anti-slip and wear-resistant pad 21 can increase the friction between the arc plate 20 and the surface of the flange 3, as well as the friction between the extrusion plate 16 and the outer wall of the hopper body 1, thereby increasing the fixing effect.

[0030] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
