Description

Technical Field

[0001] This utility model relates to the field of material conveying equipment technology, specifically to a hopper conveying mechanism. Background Technology

[0002] In existing technologies, when hoppers turn, change direction, and connect at different angles, manual or AGV-driven hoppers are generally used to turn and change direction. However, manual pushing is labor-intensive, and it is difficult to push when the hopper is too heavy. It also easily leads to contamination of the material inside the hopper. AGV pushing takes up a lot of space and has a long running time, especially the reversing time, which significantly increases the work efficiency.

[0003] Therefore, a hopper conveying mechanism is provided to solve the problems of difficult turning or reversing operations and low reversing efficiency in the hopper conveying process. Utility Model Content

[0004] Therefore, this utility model provides a hopper conveying mechanism to solve at least one problem existing in the prior art.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] This utility model provides a hopper conveying mechanism, including:

[0007] A rotating base, which is fixed to the ground;

[0008] A support wheel is mounted on the rotating base;

[0009] A rotating track, which is supported above the support wheel and rolls in contact with the support wheel;

[0010] A rotary motor, which is mounted on the rotary base;

[0011] A drive sprocket, which is mounted on the output shaft of the rotary motor;

[0012] A rotating shaft, which is rotatably mounted on the rotating base and extends in the vertical direction;

[0013] The driven sprocket is connected to the driving sprocket via chain drive, and the driven sprocket is fixedly mounted on the rotating shaft.

[0014] When hoppers need to be transported, one end of the rotating track aligns with the upstream docking track, pushing the hopper from the upstream docking track onto the rotating track. Then, the rotating motor is started, and its output shaft drives the drive sprocket to rotate. The drive sprocket transmits power to the driven sprocket via a chain. Since the driven sprocket is fixed to the rotating shaft, its rotation along with the drive sprocket causes the rotating track to rotate around the shaft. Supported by support wheels, the rotating track rotates smoothly, with the support wheels rolling against the track to reduce friction and ensure smooth rotation. The hopper pushed onto the rotating track also rotates. When the hopper reaches the desired position or angle, the rotating track aligns with the downstream docking track, pushing the hopper from the rotating track onto the downstream docking track, thus completing the hopper's reversal or turn. This solves the problems of difficult turning or reversing operations and low efficiency in hopper conveying, improving the efficiency and ease of operation for hopper turning or reversing.

[0015] In some embodiments, the hopper conveying mechanism further includes:

[0016] A rotating disk, wherein the driven sprocket is mounted on the rotating shaft via the rotating disk.

[0017] In some embodiments, the hopper conveying mechanism further includes:

[0018] A limiting block, wherein the limiting block is mounted on the rotating base;

[0019] A stop block is installed on the rotating disk. When the rotating disk rotates to a preset limit position, the stop block abuts against the limiting block.

[0020] In some embodiments, there are two limiting blocks, which are spaced apart on the rotating base.

[0021] In some embodiments, the hopper conveying mechanism further includes:

[0022] A chain tension adjustment device, which is used to adjust the tension of the chain.

[0023] In some embodiments, the rotating track includes:

[0024] A track frame, wherein the rotating disk is fixedly connected to the track frame;

[0025] The track is installed on both sides of the track frame.

[0026] In some embodiments, the rotating track further includes:

[0027] A support wheel guide rail is provided, which is mounted on the track frame, and the support wheel is rotatably mounted on the support wheel guide rail.

[0028] In some embodiments, the rotating track further includes:

[0029] A track motor drives the track to move linearly. Attached Figure Description

[0040] The following specific embodiments illustrate the implementation of this utility model. Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0041] To address the problems existing in the prior art, this utility model provides a hopper conveying mechanism. This hopper conveying mechanism can be considered as a rotating (reversing) track for the hopper. A track motor transports the hopper from the upstream docking track to the center of the rotating track 3 and then stops. The rotating motor 4 starts, and the hopper rotates with the rotating track 3 at a predetermined angle or to a predetermined position. After reaching the desired position, the rotating track 3 docks with the downstream docking track, and the track motor starts again, transporting the hopper onto the downstream docking track, thus completing the hopper's turning or reversing. Throughout the entire operation, manual intervention is minimal, the automatic rotating conveying is stable, and labor costs are reduced.

[0042] In general, the hopper conveying mechanism includes a gear rotating mechanism and a rotating track 3. The gear rotating mechanism is fixed to the ground, and the rotating track 3 is flexibly fixed to the driven sprocket 7 of the rotating mechanism. The rotating motor 4 of the rotating mechanism starts, driving the transmission mechanism to rotate, thereby driving the rotating track 3 to rotate. It should be understood that when the outlet docking track of the rotating track 3 is on the left, the rotating mechanism rotates clockwise, causing the hopper to rotate and turn; when it rotates counterclockwise, the track rotates and turns normally. When the docking track of the rotating track 3 is on the right, the rotating mechanism rotates clockwise, causing the rotating track 3 to rotate and turn normally; when it rotates counterclockwise, it causes the hopper to rotate and turn. The inlet and outlet docking tracks of the rotating track 3 are the same track, and the clockwise or counterclockwise rotation of the rotating mechanism only serves to change the direction of the hopper.

[0043] In one specific implementation, such as Figures 1-4As shown, the hopper conveying mechanism provided by this utility model includes a rotating base 1, a support wheel 2, a rotating track 3, a rotating motor 4, a drive sprocket 5, a rotating shaft 6, a driven sprocket 7, a chain 12, and a rotating disk 11. The rotating base 1 is fixed to the ground, the support wheel 2 is mounted on the rotating base 1, and the rotating track 3 supports the support wheel 2 above it and rolls in contact with it. The rotating motor 4 is mounted on the rotating base 1, the drive sprocket 5 is mounted on the output shaft of the rotating motor 4, and the rotating shaft 6 is rotatably mounted on the rotating base 1 and extends vertically. The driven sprocket 7 is connected to the drive sprocket 5 via the chain 12, the driven sprocket 7 is fixedly mounted on the rotating shaft 6, and the rotating track 3 rotates with the driven sprocket 7.

[0044] When hoppers need to be transported, one end of the rotating track 3 connects with the upstream docking track, and the hopper is pushed from the upstream docking track onto the rotating track 3. Then, the rotating motor 4 is started, and the output shaft of the rotating motor 4 drives the drive sprocket 5 to rotate. The drive sprocket 5 transmits power to the driven sprocket 7 through the chain 12. Since the driven sprocket 7 is fixedly installed on the rotating shaft 6, as the driven sprocket 7 rotates with the drive sprocket 5, it drives the rotating track to rotate around the rotating shaft. The rotating track rotates smoothly with the support of the support wheels, and the support wheels and the rotating track make rolling contact, reducing friction and ensuring smooth rotation. At this time, the hopper pushed onto the rotating track 3 also rotates. When the hopper rotates to the required position or angle, the rotating track 3 connects with the downstream docking track, and the hopper is pushed from the rotating track 3 onto the downstream docking track, thus completing the hopper's reversal or turn. This solves the problems of difficult turning or reversing operations and low reversing efficiency in the hopper conveying process, improving the efficiency and ease of operation of hopper turning or reversing.

[0045] The hopper conveying mechanism also includes a rotary disc, through which the driven sprocket is mounted on the rotating shaft. During operation, when the driving sprocket drives the driven sprocket to rotate via a chain, the power of the driven sprocket is first transmitted to the rotary disc, which then smoothly transmits the power from the driven sprocket to the rotating track. Due to the transitional effect of the rotary disc, the rotating track can rotate more smoothly, reducing vibration and swaying caused by uneven power transmission, resulting in a more rational overall structure of the mechanism.

[0046] Furthermore, during the conveying process, the support wheel 2 rolls in contact with the rotating track 3, providing support for the rotation of the rotating track 3 and reducing friction to ensure smooth rotation. Through the cooperation of the rotating base 1, support wheel 2, rotating track 3, rotating motor 4, drive sprocket 5, rotating shaft 6, and driven sprocket 7, the rotating track 3 achieves omnidirectional rotation, enabling the hopper to change direction or turn at different angles. The rotating track 3 provides stable support and guidance for the hopper, ensuring that the hopper does not shake or tip over during conveying, effectively preventing material spillage and improving production efficiency and material utilization.

[0047] It should be understood that the rotating base 1 can be fixed to the ground with anchor bolts, or a suction cup can be installed at the bottom of the rotating base to adhere to the ground, adapting to different ground materials and installation environments. The support wheels 2 can be made of polyurethane, which has good wear resistance and shock absorption performance; or support wheels 2 with bearings can be used to further reduce friction and improve rotational flexibility. The rotating track 3 can be designed in different shapes and lengths according to the shape and size of the hopper, such as circular, elliptical, or irregularly shaped tracks, to meet the needs of different hopper conveying paths. Rotary motors 4 of different power and types can be selected, such as servo motors, which can achieve more precise speed and positioning control, improving conveying accuracy; or variable frequency motors can be used, where the rotation speed is controlled by adjusting the motor frequency to adapt to different conveying speed requirements.

[0048] Furthermore, the hopper conveying mechanism also includes a limiting block 8 and a stop block 9. The limiting block 8 is mounted on the rotating base 1, and the stop block 9 is mounted on the rotating disk 11. When the rotating disk 11 rotates to a preset limit position, the stop block 9 abuts against the limiting block 8. During the rotation of the rotating track 3, when the rotating disk 11 rotates to the preset limit position, the stop block 9 mounted on the rotating disk 11 abuts against the limiting block 8 mounted on the rotating base 1. At this time, the rotating disk 11 cannot continue to rotate, thereby limiting the rotation angle of the rotating track 3 and preventing the rotating track 3 from over-rotating. When it is necessary to change the rotation direction of the rotating track 3, the rotating motor 4 reverses, the rotating disk 11 rotates in the opposite direction, the stop block 9 separates from the limiting block 8, and the rotating track 3 continues to rotate in the new direction. In this way, the rotation angle of the rotating disk 11 can be precisely limited by the cooperation of the limit block 8 and the stop block 9, thereby ensuring that the rotating track 3 rotates within the predetermined range, avoiding conveying errors or equipment damage caused by excessive rotation, and improving the accuracy and reliability of the conveying process. At the same time, the limit structure can also prevent the rotating track 3 from colliding with other equipment, protecting the safe operation of the equipment, reducing the equipment failure rate and maintenance costs, and also ensuring the personal safety of the operators.

[0049] In practical applications, limit blocks 8 of different shapes and materials can be used. For example, limit blocks 8 made of rubber have a certain elastic buffering effect, which can reduce impact and noise when the stop block 9 abuts against the limit block 8. Alternatively, limit blocks 8 with sensors can be used. When the stop block 9 approaches the limit block 8, the sensor can detect it and send a signal to control the rotating disk 11 to stop rotating in advance, further improving the accuracy and reliability of the limit. Similarly, stop blocks 9 of different shapes and materials can be used. For example, stop blocks 9 made of metal have high strength and wear resistance. Alternatively, stop blocks 9 with ball bearings can be used. When the stop block 9 abuts against the limit block 8, the ball bearings can reduce the friction between the two, allowing the rotating disk 11 to stop rotating more smoothly.

[0050] In this embodiment, there are two limiting blocks 8, which are spaced apart on the rotating base 1. When the rotating disk 11 reaches its limit position during forward rotation, the stop block 9 abuts against one of the limiting blocks 8, restricting the rotating disk 11 from continuing to rotate forward; when the rotating disk 11 reaches its limit position during reverse rotation, the stop block 9 abuts against the other limiting block 8, restricting the rotating disk 11 from continuing to rotate in the reverse direction. This bidirectional limiting method ensures that the rotation angle of the rotating disk 11 is effectively controlled in both forward and reverse directions.

[0051] It should be understood that, depending on actual needs, a greater number of limit blocks 8 can be set to achieve more precise rotation angle control; or the layout of the limit blocks 8 can be changed, such as using multiple limit blocks 8 arranged in an arc, to achieve more flexible rotation angle restriction and adapt to more complex conveying path requirements. In addition to the limiting method using mechanical limit blocks 8 and stops 9, other limiting methods can also be used, such as electronic limiting. By installing an angle sensor on the rotating disk 11, the rotation angle of the rotating disk 11 can be monitored in real time, and the start and stop of the rotating motor 4 can be controlled by the control system to achieve precise rotation angle control.

[0052] Furthermore, the hopper conveying mechanism also includes a chain tension adjustment device 10, which is used to adjust the tension of the chain so that the chain reaches the optimal tension state.

[0053] In some embodiments, the rotating track 3 includes a track frame 31 and a track 32. The rotating disk 11 is fixedly connected to the track frame 31, and the track 32 is installed on both sides of the track frame 31. When the rotating disk 11 rotates, since the rotating disk 11 is fixedly connected to the track frame 31, the track frame 31 rotates accordingly, and the tracks 32 installed on both sides of the track frame 31 also rotate correspondingly, thereby driving the hopper installed on the track 32 to move along the track. In this way, the track frame 31 provides stable support for the track 32, can bear the weight of the hopper and the materials it carries, ensures that the track 32 will not deform or be damaged during operation, ensures that the hopper is stably placed on the track 32 and can move smoothly, effectively avoiding the phenomenon of the hopper shaking or tipping during transportation, and improving the stability of the hopper transportation.

[0054] It should be understood that track frames 31 of different shapes and materials can be used. For example, a track frame 31 made of lightweight materials can reduce the weight of the mechanism and improve the flexibility of the mechanism; or a track frame 31 made of alloy materials with high strength and high rigidity can bear greater loads and improve the bearing capacity of the mechanism. According to the shape and size of the hopper, tracks with matching shapes and sizes can be designed, such as V-shaped tracks, U-shaped tracks or flat-bottom tracks, etc., to meet the loading and transportation requirements of different hoppers; or anti-slip patterns or coatings can be provided on the surface of the track to increase the friction between the track and the bottom of the hopper, further improving the stability of the hopper on the track.

[0055] Furthermore, the rotating track 3 further includes a support wheel guide rail 33. The support wheel guide rail 33 is installed on the track frame 31, and the support wheel 2 is rollably installed on the support wheel guide rail 33. During the rotation of the rotating track 3, the support wheel 2 rolls along the support wheel guide rail 33. The shape and size of the support wheel guide rail 33 match those of the support wheel 2, which can effectively guide and restrict the support wheel 2, making the support wheel 2 always roll smoothly along the guide rail. In this way, the support wheel 2 can provide stable support force for the rotating track 3, reduce the shaking and vibration of the rotating track 3 during rotation, and improve the rotation stability and accuracy of the rotating track 3. The guiding and restricting effect of the support wheel guide rail 33 on the support wheel 2 enables the support wheel 2 to roll smoothly along the guide rail, thereby improving the rotation stability of the rotating track 3, avoiding the shaking or vibration of the rotating track 3 caused by the unsmooth rolling of the support wheel 2, and improving the smoothness of the transportation process.

[0056] The support wheel guide rail 33 can adopt different shapes and sizes, such as circular guide rails, rectangular guide rails or trapezoidal guide rails, etc., and be reasonably designed according to the shape and size of the support wheel 2 to achieve the best guiding and restricting effect; or a lubricating coating or rolling bearing can be provided on the surface of the support wheel guide rail 33 to reduce the friction between the support wheel 2 and the guide rail, and improve the flexibility and life of the rolling.

[0057] The rotating track 3 also includes a track motor 34, which drives the track 32 to move linearly. When the hopper enters the rotating track 3 from the upstream docking track or enters the downstream docking track from the rotating track 3, the track motor 34 is activated. The track motor 34 drives the track 32 to move linearly through a transmission device (such as gear transmission, belt transmission, etc.). Driven by the track motor 34, the track moves along a preset linear path, thereby driving the hopper installed on the track 32 to be conveyed linearly along the track. There is no need for manual pushing or pushing of the hopper into or out of the rotating track 3, which further reduces the degree of manual intervention and improves the degree of automation.

[0058] In practical applications, different power and type of track motors can be selected. For example, servo motors can achieve more precise speed and positioning control, improving conveying accuracy; or stepper motors can be used, achieving precise linear conveying by controlling the motor's step angle and step frequency. In addition to common transmission devices such as gear drives or belt drives, other transmission methods can also be used, such as chain drives and hydraulic drives. The appropriate transmission device should be selected according to actual needs and equipment characteristics to achieve linear motion of the track.

[0059] In general, the rotating track 3 includes a track frame 31, a track, a track motor, and a support wheel guide rail. The track frame 31 is installed on the rotating disk 11, and the track is installed on both sides of the track frame 31. The track motor drives the track to rotate, pushing the hopper forward and backward.

[0060] Furthermore, multiple photoelectric switches for detecting the hopper's position can be installed on the rotating track 3. During operation, the hopper is transported from the inlet docking track to the rotating track 3. After the photoelectric switches on the rotating track 3 detect that the hopper has reached the preset position, the track motor starts, and the hopper moves. When the photoelectric switch located at the center detects that the hopper has reached the center position, the track motor stops. The rotating motor 4 starts, driving the drive sprocket 5 to rotate. The drive sprocket 5 drives the driven sprocket 7 to rotate via the chain 12, thereby driving the rotating track 3 and the hopper on it to rotate. When the hopper reaches the end position, the photoelectric switch detects that the hopper is in place, the rotating motor 4 stops, the track motor starts, the hopper is transported to the outlet docking track, the track motor stops, the rotating motor 4 starts, and the rotating track 3 returns to the initial position.

[0061] For ease of understanding, the overall structure and working process of the hopper conveying mechanism provided by this utility model are briefly described below through an embodiment.

[0062] The hopper conveying mechanism includes a rotating base 1, support wheels 2, a chain tension adjustment device 10, a rotary motor 4 (using a brake-operated variable frequency motor), a drive sprocket 5, a chain 12, a driven sprocket 7, a rotating shaft 6, a rotating disk 11, and a limiting block 8. The rotating base 1 is fixed to the ground; the support wheels 2 are fixed to the four sides of the rotating base 1 to support the rotating track 32 and prevent it from tilting or falling; the rotary motor 4 is mounted on the rotating base 1; the drive sprocket 5 is mounted on the output shaft of the rotary motor 4; the rotating shaft 6 is flexibly mounted on the rotating base 1 as a driving shaft; the driven sprocket 7 and the rotating disk 11 are fixed to the rotating shaft 6 and can rotate freely around it; a stop block 9 is fixed to the rotating disk 11; the limiting block 8 is welded to the rotating base 1, and the chain 12 passes over the drive sprocket 5 and the driven sprocket 7. The chain tension adjustment device 10 adjusts the tension of the chain 12 to prevent excessive swaying of the rotating track. Rotary motor 4 starts, driving the drive sprocket 5 to rotate, which in turn drives the driven sprocket 7 to rotate. Once the rotation reaches its designated position, rotary motor 4 stops. If the positioning photoelectric sensor does not give a signal, the driven sprocket 7 continues to rotate. If the line-crossing photoelectric sensor detects the movement, rotary motor 4 stops. If the line-crossing photoelectric sensor does not give a signal, the stop block contacts the limit block, causing excessive force on the motor, triggering an alarm and stopping the motor.

[0063] During operation, the hopper enters the rotating track 3 via the inlet docking track. The track motor 34 starts, and the hopper continues to move. When the hopper reaches the center position of the rotating track 3, the track motor 34 stops, and the hopper stops moving. The rotating motor 4 starts, and the rotating track 3 rotates around the rotating shaft 6. After the hopper rotates to its position, the rotating motor 4 stops, and docking with the outlet track is completed. The track motor 34 starts, and the hopper moves to the outlet docking track. The track motor 34 stops, and the hopper continues to move along the outlet docking track. The rotating motor 4 starts, and the rotating track 3 rotates in the opposite direction around the rotating shaft 6, returning the rotating track 3 to its initial position and re-docking with the inlet docking track.

[0064] The hopper conveying mechanism provided by this utility model realizes the function of automatic rotation (reversal) and movement of the hopper on the track; it also realizes fully automatic rotation and conveying without manual intervention, and stable operation; it eliminates the health impact of dust on workers, reduces labor costs, and improves work efficiency.

[0065] The above specific embodiments further illustrate the purpose, technical solution, and beneficial effects of this utility model. It should be understood that the above are only specific embodiments of this utility model and are not intended to limit the scope of protection of this utility model.
