Detailed Implementation

[0045] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the embodiments and accompanying drawings. The illustrative embodiments and descriptions of this application are only for explaining this application and are not intended to limit this application.

[0046] like Figure 1As shown, in a first aspect, embodiments of this application provide a material transfer device, which includes a rotating mechanism, a first swing arm, a second swing arm 4, a hopper 2, and a controller. The rotating mechanism is typically fixed to some fixed facility. For example, if the material transfer device is used in a material handling system, the material transfer device can be fixedly connected to a material handling platform 12. The rotating mechanism has a rotating output end. The first swing arm can be designed as a welded solid-web box-shaped structure. One end of the first swing arm is rotatably connected to the rotating mechanism. A first drive mechanism 6 is connected between the first swing arm and the rotating mechanism. The first swing arm can rotate on the rotating mechanism under the drive of the first drive mechanism 6 and rotate circumferentially under the drive of the rotating mechanism, that is, the other end of the first swing arm can rotate around a... The first swing arm 4 can be designed as a welded solid box structure, with one end of the second swing arm 4 rotatably connected to the other end of the first swing arm. A second drive mechanism 5 is also connected between the second swing arm 4 and the first swing arm. The second swing arm 4 can swing on the first swing arm under the drive of the second drive mechanism 5. The hopper 2 is rotatably connected to the other end of the second swing arm 4. A third drive mechanism 3 is also connected between the hopper 2 and the second swing arm 4. The hopper 2 can swing on the second swing arm 4 under the drive of the third drive mechanism 3. The hopper 2 has a material gate 1. The rotation mechanism, the first drive mechanism 6, the second drive mechanism 5 and the material gate 1 are respectively connected to the controller for controlled operation.

[0047] In use, the rotating mechanism, under the control of the controller, can drive the first swing arm, the second swing arm 4, and the hopper 2 to rotate in three-dimensional space. The first drive mechanism 6, under the control of the controller, can drive the first swing arm, the second swing arm 4, and the hopper 2 to swing as a whole on the rotating mechanism. The second drive mechanism 5, under the control of the controller, can drive the second swing arm 4 and the hopper 2 to swing as a whole on the first swing arm. The third drive mechanism 3, under the control of the controller, can drive the hopper 2 to swing on the second swing arm 4. Through the coordinated action of the rotating mechanism, the first drive mechanism 6, and the second drive mechanism 5, the hopper 2 can be aligned with different receiving and unloading positions. The material gate 1 opens under the control of the controller to achieve unloading. During the movement of the first swing arm and the second swing arm 4, the third drive mechanism 3, driven by the controller, can adjust the posture of the hopper 2 so that the feed inlet of the hopper 2 always faces upward to prevent internal material from leaking from the feed inlet.

[0048] The material transfer device provided in this application embodiment, through the coordinated action of the rotating mechanism, the first driving mechanism 6 and the second driving mechanism 5, enables the first swing arm and the swing arm to move together to drive the hopper 2 to move in various directions in three-dimensional space, thereby facilitating the hopper 2 to quickly reach the material transfer endpoint from the material transfer start point; when the hopper 2 reaches the material transfer endpoint, the controller controls the material gate 1 to achieve automatic unloading, eliminating the need for manual operation of the material gate 1, effectively reducing the labor burden of the staff, and improving the material receiving and unloading efficiency.

[0049] In some optional embodiments, the rotating mechanism includes a rotating platform, a drive assembly 10, and a drive source 9; a slewing support 8 can be connected to the rotating platform, and the slewing support 8 rotates synchronously with the rotating platform, and the slewing support 8 facilitates the connection between the first swing arm and the rotating mechanism; the drive assembly 10 is connected to the rotating platform, and the rotating platform rotates under the drive of the drive assembly 10; the drive source 9 is connected to the drive assembly 10 to drive the rotating platform to rotate through the drive assembly 10, and the drive source 9 is usually connected to other fixed facilities, such as when the material transfer device is used in the material handling system, the drive source 9 is fixedly connected to the material handling platform 12.

[0050] Following the above, the specific structure of the drive assembly 10 is not limited. For example, it can be a belt drive mechanism, a cam linkage mechanism, a rocker linkage mechanism, a gear drive mechanism, or a worm gear drive mechanism. To facilitate implementation, control manufacturing costs, and ensure a certain motion accuracy of the rotating mechanism, in some optional embodiments, the drive assembly 10 includes a drive gear ring and a drive gear. The drive gear ring is sleeved on the rotating platform, and the rotating platform rotates synchronously with the drive gear ring. The drive gear ring has an external tooth structure. The drive gear is driven and engaged with the drive gear ring. The drive gear is also driven and connected to the drive source 9 to rotate around its own axis under the drive of the drive source 9. The drive gear ring rotates synchronously under meshing action, thereby driving the rotating platform to rotate.

[0051] To facilitate the installation of the material transfer device, in some optional embodiments, the material transfer device further includes a support platform 11, with a rotating platform rotatably connected to the support platform 11. The support platform 11 is used to connect to the material conveying platform 12. In actual implementation, the drive source 9 described above can be fixedly connected to the support platform 11.

[0052] In some optional embodiments, the support platform 11 includes a support column, a base, and stiffening ribs; the rotating platform is rotatably connected to the support column, for example, a mating groove can be opened on the rotating platform, and the rotating platform is fitted onto the support column through the mating groove. Rolling bearings and / or planar bearings can be provided between the rotating platform and the support column to ensure smooth rotation of both; the base is connected to one end of the support column along its length direction. The base has a disc-shaped structure, which can be a disc structure or a ring structure. In actual implementation, the base can be a flange. The base is fitted onto the end of the support column through an inner hole. The edge of the inner hole of the base can be welded to the support column to ensure connection strength. From the perspective of the length direction of the support column, the support column is located within the projected outline of the base. For example, the support column can be a cylinder, in which case the outer diameter of the base is larger than the outer diameter of the support column; stiffening ribs are connected between the support column and the base. There can be multiple stiffening ribs, which are evenly distributed around the support column. The stiffening ribs are welded to the side wall of the support column and to the disc surface of the base. By setting up the chassis, especially by setting the chassis to a flange, it is easy to connect the material transfer device as a whole with other fixed facilities. After the chassis is connected to the fixed facilities, the chassis has a large support surface, which can ensure the overall stability of the material transfer device after installation.

[0053] In some alternative embodiments, the first drive mechanism 6 is configured as a first telescopic rod, wherein the two ends of the first telescopic rod are rotatably connected to the first swing arm and the rotating mechanism, respectively.

[0054] In this embodiment, the first drive mechanism 6 is used to drive the first swing arm, the second swing arm 4, the hopper 2, and the material inside the hopper 2. Therefore, the number of first drive mechanisms 6 can be set to multiple to increase the output torque. At the same time, the setting of multiple first drive mechanisms 6 can avoid safety accidents caused by the failure of a single drive mechanism. In actual implementation, the number of first drive mechanisms 6 can be configured as two, with the two first drive mechanisms 6 arranged in parallel and spaced apart. The first drive mechanism 6 can be specifically configured as a hydraulic rod, which can provide a stable and large output torque under the premise of easy availability.

[0055] In some optional embodiments, the second drive mechanism 5 is configured as a second telescopic rod, wherein both ends of the second telescopic rod are rotatably connected to the first swing arm and the second swing arm 4, respectively. The second drive mechanism 5 is located between the two first drive mechanisms 6, thereby ensuring that the force on the second swing arm 4 is relatively balanced when swinging, which is beneficial to improving the smoothness of the movement. In actual implementation, the second drive mechanism 5 can also be configured as a hydraulic rod.

[0056] In some alternative embodiments, the third drive mechanism 3 is configured as a third telescopic rod, wherein the two ends of the third telescopic rod are rotatably connected to the second swing arm 4 and the hopper 2, respectively.

[0057] In this embodiment, the third drive mechanism 3 needs to control the posture of the hopper 2 in real time to ensure that the feed opening of the hopper 2 always faces upward. Since the hopper 2 is usually a non-elongated structure, the length of the third drive mechanism 3 is usually set to be relatively short when it is a telescopic rod. Considering the accuracy of the movement of the hopper 2, the number of third drive mechanisms 3 is set to two. In actual implementation, the third drive mechanism 3 can also be configured as a hydraulic rod.

[0058] In some optional embodiments, a bracket is also welded onto the hopper 2. When the hopper 2 is placed on the ground to receive material, the bracket can be used to support the hopper 2 and reduce the load-bearing pressure on the first swing arm and the second swing arm 4.

[0059] In some optional embodiments, a drive rod is connected to the material gate 1, and a fourth telescopic rod is rotatably connected to the hopper 2. The fourth telescopic rod is rotatably connected to the drive rod, wherein the length direction of the drive rod forms an angle with the surface of the material gate 1. By controlling the extension and retraction of the fourth telescopic rod through a controller, the drive rod can be driven to move, thereby controlling the opening and closing of the material gate 1 to achieve automatic unloading.

[0060] In some optional embodiments, a rubber cover may be provided at the feed inlet of the hopper 2 to prevent material spillage when the hopper 2 receives material.

[0061] like Figures 2-4 As shown, in a second aspect, embodiments of this application provide a material handling system, which includes a material handling platform 12, a material handling device 13, a receiving container 14, and a material transfer device 15 as described in the first aspect; the material handling device 13 is located on the material handling platform 12; the receiving container 14 is located on one side of the material handling platform 12; the material transfer device 15 is connected to the material handling platform 12 and is used to transfer coarse material to the receiving container 14, or to transfer coarse material to the material handling device 13.

[0062] The material handling system provided in this application embodiment, through the setting of the material transfer device 15, allows the hopper 2 in the material transfer device 15 to move arbitrarily within a certain range in three-dimensional space. A single material transfer device 15 can be applied to situations where material is received and unloaded at multiple locations, reducing the system complexity of the material handling system, reducing the overall space occupation of the material handling system, and helping to improve the material receiving and unloading efficiency of the material handling system.

[0063] In some optional embodiments, a limit switch is provided on the material conveying platform 12. The limit switch is used to detect the rotation angle of the material transfer device 15 to prevent the material transfer device 15 from rotating excessively and causing the hopper to collide with other structures.
