[0075] 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.

[0076] In one specific implementation, such as Figures 1-3 As shown, the material bucket tilting and lifting machine provided by this utility model includes a frame 1, a guide rail 2, a bucket holding mechanism 3, and a drive mechanism. The guide rail 2 is mounted on the frame 1 and includes a first vertical section, a horizontal section, and a second vertical section in its extending direction. A first inflection point is formed between the first vertical section and the horizontal section, and a second inflection point is formed between the horizontal section and the second vertical section. The bucket holding mechanism 3 has a bucket mounting position, where the bucket to be lifted 100 is detachably mounted. This bucket holding mechanism 3 is particularly suitable for smaller buckets. The drive mechanism is connected to the bucket holding mechanism 3, and the bucket holding mechanism 3 moves along the extending direction of the guide rail 2 under the action of the drive mechanism. When the bucket holding mechanism 3 moves to the first inflection point, it tilts horizontally, and when it moves to the second inflection point, it tilts vertically.

[0077] During operation, the bucket to be lifted 100 is fixed on the bucket-holding mechanism 3. Driven by the drive mechanism, the bucket-holding mechanism 3 moves along the guide rail 2, achieving horizontal flipping when passing the first inflection point and vertical flipping when passing the second inflection point, ultimately lifting the bucket to the designated height and flipping it to the target position. After unloading, the drive mechanism moves in the opposite direction to reset the bucket. In this way, the bucket tilting and lifting machine realizes the lifting and tilting of the bucket, improving material turnover efficiency, and is especially suitable for occasions with limited space.

[0078] like Figures 4-5As shown, frame 1 is welded from stainless steel plates and square tubes, and is fixed to the ground using a base plate 11, making the entire frame 1 perpendicular to the ground. Specifically, frame 1 includes a base plate 11, a truss 12, and a surrounding plate 13; wherein, the base plate 11 is fixed to the ground, the truss 12 is installed on the base plate 11, the truss 12 has an L-shaped structure, the first side (i.e., the vertical side) of the L-shaped structure forms a vertical segment, the second side (i.e., the horizontal side) of the L-shaped structure forms a horizontal segment, the bottom of the first side is installed on the base plate 11, and the surrounding plate 13 is installed on the outer periphery of the truss 12. The base plate 11 is fixed to the ground, and the truss 12 supports the entire equipment through the base plate 11, providing a stable installation foundation for the guide rail 2 and the bucket clamping mechanism 3; the L-shaped truss 12 has a simple structure and high stability, and can effectively support the weight of the equipment and the forces generated by its movement, and the surrounding plate 13 is installed on the outer periphery of the truss 12.

[0079] In some embodiments, the drive mechanism includes a motor 54, a drive sprocket assembly 5, a first driven sprocket assembly 6, a second driven sprocket assembly 7, and a chain 8; wherein, the drive sprocket assembly 5 is connected to the output shaft of the motor 54 and rotates under the drive of the motor 54; there are two first driven sprocket assemblies 6, which are respectively installed at the first corner and the second corner of the guide rail 2; the second driven sprocket assembly 7 is installed at the end of the stroke of the guide rail 2; the chain 8 passes around the drive sprocket 52 of the drive sprocket assembly 5, each of the first driven sprockets of the first driven sprocket assembly 6, and the second driven sprocket of the second driven sprocket assembly 7; the bucket-holding mechanism 3 is installed on the chain 8 and moves along the guide rail 2 with the chain 8.

[0080] During operation, motor 54 drives the drive sprocket 52 to rotate, which in turn drives the bucket-holding mechanism 3 to move along guide rail 2 via chain 8. The first driven sprocket assembly 6 and the second driven sprocket assembly 7 guide the direction of chain 8. Chain drive has a simple structure, high reliability, and can achieve precise position control and a large load capacity. Synchronous belt drive can also be used instead of chain drive to reduce noise and improve transmission accuracy.

[0081] like Figures 6-8 As shown, the drive sprocket assembly 5 includes a motor 54 with a brake structure, a drive shaft 51, a second bearing seat 53, and a drive sprocket 52. Two sets of second bearing seats 53 support the drive shaft 51, and the drive sprocket 52 is mounted and fixed on the drive shaft 51. The motor 54 drives the drive shaft 51 to rotate, which in turn drives the chain 8 to rotate, thereby realizing the lifting and lowering of the material bucket.

[0082] Specifically, the drive sprocket assembly 5 includes a drive shaft 51, a drive sprocket 52, and a second bearing housing 53. The drive shaft 51 is connected to the output shaft of the motor 54. The drive sprocket 52 is mounted on the drive shaft 51 and rotates with the drive shaft 51. The second bearing housing 53 is mounted on the frame 1, and the drive shaft 51 is rotatably mounted on the second bearing housing 53.

[0083] During operation, the output shaft of the motor 54 is connected to the drive shaft 51 via a coupling or transmission belt. The drive shaft 51 drives the drive sprocket 52 to rotate, thereby driving the chain 8 to move. This structure ensures the stability and reliability of power transmission, while the drive shaft 51 is supported by the bearing housing, reducing shaft wear and vibration.

[0084] It should be understood that the terms "first" and "second" in the text refer to different components with the same name, and are used only for the convenience of description. They do not imply any limitation, nor should they be interpreted as any order.

[0085] The first driven wheel assembly and the second driven wheel assembly mentioned above are only different in their positions, but their composition structures are roughly the same. The specific structure of the first driven wheel assembly will be briefly described below.

[0086] like Figure 9 As shown, the driven sprocket assembly (including the first driven wheel assembly and the second driven wheel assembly) includes a driven shaft 61, a driven sprocket 62, a third bearing seat 63, etc. The driven shaft 61 is supported by a double bearing seat, and the driven sprocket 62 is installed and fixed on the driven shaft 61. The chain 8 drives the driven sprocket 62 to rotate, which drives the material bucket to rise and fall.

[0087] In some embodiments, the drive mechanism further includes a tensioner assembly 9, which is installed between the second driven wheel assembly and the driving sprocket assembly 5, with the chain 8 passing around the tension sprocket 91 of the tensioner assembly 9. The tensioner assembly 9 applies tension to the chain 8 through the tension sprocket 91, ensuring that the chain 8 maintains proper tension during operation and preventing the chain 8 from becoming slack or skipping teeth.

[0088] like Figure 10 and Figure 11As shown, the tensioning wheel assembly 9 includes a tensioning sprocket 91, a tensioning shaft 92, and an adjusting assembly. Two tensioning sprockets 91 are fixed to both ends of the tensioning shaft 92, and the adjusting assembly is mounted on both ends of the tensioning shaft 92 via first bearing seats 95. The adjusting assembly includes a guide seat 93, a sliding block 94, an adjusting rod 96, a movable rod 97, and a spring 98. The guide seat 93 is mounted on the frame 1 and has a slide rail. The sliding block 94 slidably slides along the slide rail. The first bearing seat 95 is fixed to the sliding block 94 and mounted on the guide seat 93; the adjusting rod 96 passes through the sliding block 94 and is fixed to the guide seat 93, the sliding block 94 can move axially along the adjusting rod 96, the movable rod 97 passes through the sliding block 94, the sliding block 94 can move axially along the movable rod 97, the spring 98 is sleeved on the movable rod 97, one end of the spring 98 abuts against the sliding block 94, and the other end abuts against the guide seat 93.

[0089] During use, the sliding block 94 moves along the slide rail under the guidance of the adjusting rod 96 and the movable rod 97, guided by the elastic force of the spring 98, thereby adjusting the position of the tension shaft 92 and adjusting the tension of the chain 8. This structure can automatically compensate for the elongation or shortening of the chain 8, ensuring that the chain 8 always maintains an appropriate tension, thus improving the operational stability and reliability of the equipment.

[0090] In specific applications, the tensioning wheel assembly includes a tensioning shaft 92 (in a driven position), a tensioning sprocket 91, a first bearing seat 95, a guide seat 93, an adjusting rod 96, a movable rod 97, a spring 98, and a sliding block 94. The tensioning shaft 92 is supported by double bearing seats, and the tensioning sprocket 91 is mounted and fixed on the tensioning shaft 92. The first bearing seats 95 are mounted at both ends of the tensioning shaft 92 and are fixed to the sliding block 94. The sliding block 94 is mounted on the slide rail of the guide seat 93. The adjusting rod 96 passes through the sliding block 94 and is fixed to the guide seat 93, secured with a nut. The movable rod 97 passes through the sliding block 94 and is mounted on the guide seat 93. The spring 98 is mounted on the movable rod 97, and its two end faces contact the sliding block 94 and the guide seat 93, forming an automatic tensioning device for the chain 8. This device is used to adjust the tension of the chain 8 and ensure its normal operation.

[0091] In some embodiments, such as Figure 12 and Figure 13As shown, the bucket-holding mechanism 3 includes a platform 31, a guide rod 32, and a rotating shaft seat 33. The bucket mounting position is set on the platform 31, the guide rod 32 is mounted on the platform 31, and a contact block 34 is mounted on the platform 31 via an adapter 38. A second rotating shaft 36 is slidably mounted on the guide rod 32 along the axial direction. The second rotating shaft 36 is connected to the chain 8 and moves with the chain 8 in the extension direction of the guide rail 2. The rotating shaft seat 33 is mounted on the platform 31, and a first rotating shaft 35 is fixedly mounted on the rotating shaft seat 33. The first rotating shaft 35 is connected to the chain 8 and moves with the chain 8 in the extension direction of the guide rail 2.

[0092] The bucket-holding mechanism 3 is connected to the chain 8 via a rotating shaft seat 33 and moves along the guide rail 2 with the chain 8. The contact block 34 is used to detect the position of the bucket-holding mechanism 3 or trigger related actions. This structure ensures that the bucket-holding mechanism 3 remains stable during movement and realizes the position detection or triggering function through the contact block 34, thereby improving the automation level of the equipment.

[0093] The bucket-holding mechanism 3 also includes a clamp 37, which is detachably mounted on the platform 31. The bucket 100 to be lifted is detachably clamped within the clamp 37. The clamp 37 opens and closes via a mechanical or hydraulic device, firmly holding the bucket within it to ensure it does not loosen during lifting and tilting. The clamp 37 is designed to accommodate buckets of different sizes, improving the equipment's versatility and reliability while ensuring the bucket's stability during movement. Vacuum suction cups or magnetic clamping devices can be used instead of the clamp 37 to accommodate buckets of special shapes or materials.

[0094] In a specific application scenario, the bucket-holding mechanism 3 includes a platform 31, a rotating shaft seat 33, a first rotating shaft 35, a second rotating shaft 36, a guide rod 32, a linear bearing, and a contact block 34. The rotating shaft seat 33 is fixed to the platform 31, the first rotating shaft 35 is fixed to the rotating shaft seat 33, and the guide rod 32 is fixed to the platform 31. The linear bearing is mounted on the second rotating shaft 36 and the guide rod 32, driving the second rotating shaft 36 to reciprocate on the guide rod 32. The contact block 34 is fixed to the platform 31 and touches the limit switch on the guide rail 2. Both ends of the first rotating shaft 35 are connected to the chain 8 via bearing seats and can rotate freely relative to the chain 8. Both ends of the second rotating shaft 36 are connected to the chain 8 via bearing seats and can rotate freely relative to the chain 8. When the bucket-holding mechanism 3 rises or falls to a 90° corner, the first rotating shaft 35 and the second rotating shaft 36 rotate, and simultaneously, the second rotating shaft 36 reciprocates on the guide rod 32.

[0095] In some embodiments, the frame 1 is also equipped with a descent deceleration photoelectric switch 41, a descent stop photoelectric switch 42, a descent safety protection photoelectric switch 43, an ascent deceleration photoelectric switch 44, an ascent stop photoelectric switch 45, and an ascent safety protection photoelectric switch. When the contact block 34 on the bucket-holding mechanism 3 touches the descent deceleration photoelectric switch 41, it indicates that the descent deceleration position has been reached, and the chain 8 drives the bucket-holding mechanism 3 to begin decelerating and descending. When the contact block 34 on the bucket-holding mechanism 3 touches the descent stop photoelectric switch 42, it indicates that the descent stop position has been reached, and the chain 8 drives the bucket-holding mechanism 3 to stop descending. When the contact block 34 on the bucket-holding mechanism 3 touches the descent safety protection photoelectric switch 43... When the contact block 34 on the bucket holding mechanism 3 touches the upward deceleration photoelectric switch 44, it indicates that the upward deceleration position has been reached, and the chain 8 drives the bucket holding mechanism 3 to begin decelerating upwards. When the contact block 34 on the bucket holding mechanism 3 touches the upward stop photoelectric switch 45, it indicates that the upward stop position has been reached, and the chain 8 drives the bucket holding mechanism 3 to stop upwards. When the contact block 34 on the bucket holding mechanism 3 touches the upward safety protection photoelectric switch, it indicates that the upward limit position has been reached, and the chain 8 drives the bucket holding mechanism 3 to brake urgently, and the alarm sounds.

[0096] In general, the bucket tilting and lifting machine includes a frame 1, a drive sprocket assembly 5, multiple driven sprocket assemblies, a tension wheel assembly, and a bucket holding mechanism 3. A variable frequency geared motor 54 (with a brake) drives the drive sprocket assembly 5 to rotate, which in turn drives the chain 8. The multiple driven sprocket assemblies are positioned at fixed points, causing the chain 8 to form a circular motion. The bucket holding mechanism 3 reciprocates around the circular chain 8. When the bucket holding mechanism 3 reaches a 90-degree turn, the connection point with the chain 8 automatically rotates, and the guide rod in the bucket holding mechanism 3 automatically retracts and extends, thus achieving functions such as bucket tilting and docking.

[0097] During operation, the bucket tilting and lifting machine is fixed in a specific area. The bucket is moved onto the bucket clamping mechanism 3, which clamps the bucket using clamping clamps 37. The equipment is started, and the chain 8 pulls the bucket clamping mechanism 3 upward. At the first 90° turn, the bucket clamping mechanism 3 rotates 90° around the driven sprocket at that point. The chain 8 then pulls the bucket clamping mechanism 3 horizontally. When the contact block 34 of the bucket clamping mechanism 3 collides with the upper deceleration limit switch, the chain 8 decelerates the bucket clamping mechanism 3. At the second 90° turn, the bucket clamping mechanism 3 rotates 90° around the sprocket. °, the chain 8 pulls the bucket holding mechanism 3 vertically. When the contact block 34 of the bucket holding mechanism 3 collides with the upper stop limit switch, the chain 8 pulls the bucket holding mechanism 3 to stop. At the same time, it docks with the next station to unload the material. After unloading, it returns along the original path. When the contact block 34 of the bucket holding mechanism 3 collides with the lower deceleration limit switch, the chain 8 pulls the bucket holding mechanism 3 to decelerate. When the contact block 34 of the bucket holding mechanism 3 collides with the lower stop limit switch, the chain 8 pulls the bucket holding mechanism 3 to stop. The bucket is then manually removed, and another bucket is used to repeat the above process.

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.
