Abstract
Description
Technical Field
[0001] This utility model relates to the field of dock hopper technology, specifically an adjustable angle hopper gate control device. Background Technology
[0002] Terminal truck hoppers are important pieces of equipment used for loading and unloading bulk cargo at ports. They are mainly used to unload bulk materials from ships onto trucks or from trucks onto other conveying equipment. As an important auxiliary production tool for unloading ocean-going vessels, the truck hoppers at bulk cargo terminals control the speed of cargo flow by adjusting the size of the hopper gate during operation. Currently, all hoppers have automatic unloading functions.
[0003] However, the opening size of the hopper gate is set in the background by setting time or installing limit switches to control the opening size of the hopper gate. Due to the mechanical reasons of the hopper, the gap between the synchronous rotating teeth is large. Often, the opening size of each hopper is different in the same amount of time. Due to space limitations, the limit switch control can only open in one position, which cannot meet the needs of discharging multiple types of materials. This leads to poor material discharge during the discharge process and causes hopper blockage. Utility Model Content

One end of the connecting shaft extends through the end cover flange into the hopper and is connected to the drive shaft of the gate panel through a coupling.
[0008] Preferably, the other end of the connecting shaft passes through the connecting frame and extends to the detection end inside the angle sensor. The connecting frame is connected to the outer wall of the hopper by welding. The angle sensor is located outside the connecting frame and corresponds to the angle of the end cover flange and the connecting shaft.
[0009] Preferably, the sleeve is connected to the inner wall of the connecting frame by bolts, and the connecting shaft passes through the inside of the sleeve. One end of the protrusion is connected to the outer wall of the connecting shaft by bolts and is located in the inner area of the sleeve outside the connecting shaft.

[0012] Compared with the prior art, the beneficial effects of this utility model are:
[0013] 1. By pre-setting the opening and closing angle of the hopper gate before operation, when the hopper gate is opened, the drive shaft drives the gate to rotate while the connecting shaft is linked, so that the other end of the connecting shaft rotates between the detection ends of the angle sensor. The angle sensor detects whether the opening angle of the gate corresponds to the set angle, and controls the gate to stop after the angle corresponds, thus realizing precise control of the gate opening and closing and improving the accuracy of the gate opening and closing angle.
[0014] 2. By sleeved outside the connecting shaft, and with the protrusion outside the connecting shaft embedded in the through groove inside the sleeve and abutting against the arc plate, when the connecting shaft rotates, the protrusion pushes the arc plate to slide in the through groove, causing its other end to extend into the positioning groove. At the same time as the extension, the corresponding push rod extending out of the positioning groove abuts and presses against it, causing it to retract and press the trigger button in the cavity. By comparing the trigger range of the trigger button in multiple cavities with the angle detected by the angle sensor, the opening and closing angle of the door panel is further detected and compared with the angle sensor signal to reduce errors.
[0015] This invention connects an angle sensor to the drive shaft of the hopper gate panel. The angle sensor detects the rotation angle of the drive shaft and the gate panel, enabling precise control of the gate panel's opening and closing angle. Simultaneously, the detection results of the angle sensor are compared to ensure detection accuracy, reduce errors, and improve the precision of gate panel angle control. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0022] Example 1: Please refer to Figures 1-3An adjustable angle hopper gate control device includes a hopper 1. A detection component for detecting the opening angle of the feed inlet is installed outside the hopper 1. The detection component includes an end cap flange 2 located outside the feed inlet at the bottom of the hopper 1, corresponding to the drive shaft area at one end of the inner door panel of the hopper 1. A connecting shaft 3 is installed outside the end cap flange 2. One end of the connecting shaft 3 is connected to the drive shaft of the door panel via a coupling, and the other end extends into an angle sensor 9 and is connected to the detection end of the sensor. When the drive shaft drives the door panel to rotate, the connecting shaft 3 rotates synchronously via the coupling. Simultaneously, the other end of the connecting shaft 3 and the detection end of the angle sensor 9 will generate a position, thereby allowing the angle sensor 9 to monitor the rotation angle of the door panel. A protrusion 301 is provided on the outer wall of shaft 3, and a connecting frame 4 is provided at the other end of connecting shaft 3 to provide auxiliary support for the position of connecting shaft 3 and to install angle sensor 9. A sleeve 5 is provided on the inner wall of connecting frame 4, and angle sensor 9 is provided on the outside of connecting frame 4. End cover flange 2 is connected to the outside of hopper 1 by bolts and is located in the area of drive shaft of material outlet door panel on the inner wall of hopper 1. One end of connecting shaft 3 passes through end cover flange 2 and extends into hopper 1 and is connected to drive shaft of door panel through coupling. The other end of connecting shaft 3 passes through connecting frame 4 and extends to detection end inside angle sensor 9. Connecting frame 4 is connected to outer wall of hopper 1 by welding. Angle sensor 9 is located outside connecting frame 4 and corresponds to the angle of end cover flange 2 and connecting shaft 3.
[0023] In this embodiment: the drive shaft of the door panel is linked with the connecting shaft 3 through a coupling. Before the hopper 1 operates, the angle sensor 9 is preset with an angle. Then, the drive shaft drives the connecting shaft 3 to rotate synchronously while controlling the door panel to rotate and open. At the same time, the other end of the connecting shaft 3 and the detection end of the angle sensor 9 are displaced. Thus, the angle sensor 9 can cooperate with the connecting shaft 3 to detect the angle of the door panel's rotation and opening. After the door panel rotates to the preset angle, the drive shaft is controlled to stop. The angle sensor 9 replaces the original time control, realizing precise control of the hopper door opening. Compared with limit control, angle control can realize the selection of any angle from 0-90°, reducing the use of limit switches, reducing on-site wiring, reducing costs, and realizing the function of precise control of the hopper door.
[0024] Example 2: This example is an improvement on Example 1. For details, please refer to [link / reference]. Figures 1-4The inner wall of the sleeve 5 is provided with a through groove 6 for housing the arc-shaped plate 601 and for positioning the angle of the arc-shaped plate 601 during sliding, in conjunction with the positioning groove 7. The protrusion 301 on the outside of the connecting shaft 3 is embedded in the through groove 6. When the connecting shaft 3 rotates, the protrusion 301 rotates synchronously within the through groove 6, pushing the arc-shaped plate 601 against and extending it into the positioning groove 7. Simultaneously, one end of the arc-shaped plate 601 is magnetically connected to the protrusion 301 via a magnet. The inner wall of the through groove 6 is provided with the arc-shaped plate 601. The end is provided with a positioning groove 7, and the inner wall of the positioning groove 7 is provided with multiple cavities 8 for housing the push rod 803 and positioning the angle of the push rod 803 during extension and retraction. Each cavity 8 is provided with a trigger button 801 and a spring 802. The spring 802 is used to support the push rod 803 and push one end of it to extend from the cavity 8 into the positioning groove 7. When the arc plate 601 extends into the positioning groove 7, it abuts against the push rod 803 extending into the cavity 8, causing it to retract into the cavity 8 and press the trigger button 801 to activate it. After the trigger button 801 is activated, it sends a signal. The number and position of the trigger buttons 801 activated in multiple cavities 8 can assist in the angle detection of the door panel, and the detection result is compared with that of the angle sensor 9 to further improve the accuracy of the detection. A push rod 803 is provided at one end of the spring 802; the sleeve 5 is connected to the inner wall of the connecting frame 4 by bolts, and the connecting shaft 3 passes through the inside of the sleeve 5. One end of the protrusion 301 is connected to the outer wall of the connecting shaft 3 by bolts, and is located in the area inside the sleeve 5 outside the connecting shaft 3. The other end of the protrusion 301 An arc-shaped plate 601 is located in the through groove 6 extending into the inner wall of the sleeve 5 and is slidably connected to the inner wall of the through groove 6. A magnet is installed at one end of the arc-shaped plate 601 and is magnetically attracted to the protrusion 301. The other end is an arc-shaped structure that extends into the positioning groove 7. Multiple cavities 8 are distributed in a ring on the inner wall of the positioning groove 7. One end of the push rod 803 is located in the cavity 8 and is slidably connected to the inner wall of the cavity 8. The other end is an arc-shaped structure that extends into the positioning groove 7. The two ends of the spring 802 are connected to the inner wall of the cavity 8 and the push rod 803, respectively.
[0025] In this embodiment: while the connecting shaft 3 rotates, the external protrusion 301 rotates in conjunction with the through groove 6 on the inner wall of the sleeve 5. The protrusion 301 is connected to the arc plate 601 by magnetism. When the connecting shaft 3 rotates, it pushes the arc plate 601 to extend into the positioning groove 7. The arc angle at one end of the arc plate 601 abuts and presses the top rod 803 extending from the inner wall of the positioning groove 7, causing it to retract into the cavity 8. At the same time as the top rod 803 retracts, it presses and activates the trigger button 801 in the cavity 8. Then, the opening and closing angle of the door panel is detected by the number and position of the activated trigger buttons 801 in the multiple cavities 8. The detection result is compared with the detection result of the angle sensor 9 to improve the detection accuracy of the angle sensor 9 and reduce the generation of errors.
