Description

Technical Field

[0001] This application belongs to the field of automated production line technology and relates to a discrete material discharge device. Background Technology

[0002] In the field of discrete material handling, smooth material discharge is crucial for ensuring production continuity. However, traditional discharge devices typically have the outlet at the bottom, which presents some technical limitations in practical use. For example, the "arching effect" can easily occur, causing material blockage at the outlet and affecting stable discharge. To address this issue, existing technologies usually add auxiliary devices such as vibrators or agitators to the outside of the device. These additional auxiliary devices not only increase the complexity of the system but also lead to additional energy consumption. Furthermore, the impact force generated by the vibration device may affect the physical properties of the material, and its operating noise can also impact the working environment. From a resource utilization perspective, this technical solution still has room for improvement in energy consumption control and material protection. Utility Model Content

[0003] The purpose of this application is to provide a discrete material discharge device, which aims to solve the technical problems of dependence on additional arch-breaking devices and unstable discharge of discrete materials in the prior art.

[0004] To achieve the above objectives, the technical solution adopted in this application embodiment is as follows: This application provides a discrete material discharge device, including a cylindrical base, a drive motor disposed at the bottom of the cylindrical base, and a discharge cylinder disposed inside the cylindrical base and driven to rotate by the drive motor. The discharge cylinder has at least two independent hoppers, and the cylinder wall of the discharge cylinder is provided with discharge ports corresponding to each of the hoppers. The side wall of the cylindrical base is provided with a spiral guide groove. When the discharge cylinder rotates, the discharge ports of each hopper can communicate with the spiral guide groove so that the discrete material is discharged from the discharge port through the spiral guide groove.

[0005] Specifically, the discharge port is a rectangular discharge port arranged longitudinally along the cylinder wall.

[0006] Specifically, the bottom wall of the discharge cylinder is conical, and a connecting rod is provided at the top of the conical bottom wall. The bottom of the connecting rod is connected to the output shaft of the drive motor. The discharge cylinder is provided with a partition plate for separating the material bin, and the connecting rod is located at the center of the partition plate.

[0007] Specifically, the discharge cylinder also has a top cover, which is fixedly connected to the top of the connecting rod by fasteners.

[0008] Specifically, the discharge cylinder has multiple ribs evenly arranged on its wall to assist in discharge.

[0009] Specifically, rolling members for reducing friction are further provided between the cylindrical base and the bottom of the discharge barrel.

[0010] Specifically, the rolling members are a plurality of rollers uniformly arranged along the circumference of the cylindrical base, and the bottom of the discharge barrel is placed on the plurality of rollers.

Therefore, they should not be construed as limitations on this application.

[0020] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, "multiple" means two or more, and "several" means one or more, unless otherwise explicitly specified.

[0021] Reference Figure 1 This application provides a discrete material discharge device, including a cylindrical base 10, a drive motor 20 disposed at the bottom of the cylindrical base 10, and a discharge cylinder 30 disposed inside the cylindrical base 10 and driven to rotate by the drive motor 20. The discharge cylinder 30 has at least two independent hoppers 31 (in this embodiment, there are two hoppers 31). The cylinder wall of the discharge cylinder 30 is provided with discharge ports 32 corresponding to each hopper 31. The side wall of the cylindrical base 10 is provided with a spiral guide groove 40. When the discharge cylinder 30 rotates, the discharge ports 32 of each hopper 31 can communicate with the spiral guide groove 40 so that the discrete material is discharged from the discharge port 32 through the spiral guide groove 40.

[0022] In this application, when the discharge cylinder 30 rotates under the drive of the drive motor 20, at least two discharge ports 32 move relative to the spiral guide groove 40 and connect with the spiral guide groove 40 to form an involute discharge channel. This involute top-down discharge mode changes the traditional bottom discharge to side layering and peeling, so that the discharge can be smooth, linear and controllable without the need for additional arch-breaking devices, reducing the equipment's dependence on arch-breaking devices, improving the accuracy of material processing, and optimizing the equipment's resource utilization efficiency.

[0023] Specifically, in this embodiment, the discharge port 32 is a rectangular discharge port 32 arranged longitudinally along the cylinder wall. When the discharge cylinder 30 rotates, the two rectangular discharge ports 32 and the spiral guide groove 40 will sequentially form a dynamic V-shaped opening from top to bottom, gradually widening. When the rectangular discharge port 32 of the first hopper 31 first forms a V-shaped channel with the edge of the spiral guide groove 40, the material in the first hopper 31 is discharged; as the discharge cylinder 30 continues to rotate, the second rectangular discharge port 32 subsequently forms a V-shaped channel with the edge of the spiral guide groove 40, realizing the discharge of material in the second hopper 31. The opening area of ​​the rectangular discharge port 32 has a highly linear relationship with the rotation angle, thereby achieving precise material flow control.

[0024] Reference Figure 2 In this embodiment, the bottom wall 35 of the discharge cylinder 30 is conical, and a connecting rod 33 is provided at the top of the conical bottom wall 35. The bottom of the connecting rod 33 is connected to the output shaft of the drive motor 20. The discharge cylinder 30 is provided with a partition plate 34 for dividing and forming a hopper 31, and the connecting rod 33 is located at the center of the partition plate 34. By designing the bottom wall 35 as conical, the bottom surface has an irregular slope design, ensuring that the tail material is completely discharged and avoiding residual material. The partition plate 34 divides the discharge cylinder 30 into two independent hoppers 31, which can process two different materials at the same time. The material pressure in a single hopper 31 is reduced by sequential discharge.

[0025] Furthermore, the discharge cylinder 30 has multiple ribs 36 evenly arranged on its wall to assist in material discharge. When the discharge cylinder 30 rotates, the ribs 36 move the material, effectively improving material flowability and ensuring smooth discharge.

[0026] In this embodiment, the discharge cylinder 30 also has a top cover 37, which is fixedly connected to the top of the connecting rod 33 by fasteners (not labeled in the figure). The top cover 37 protects the material inside the discharge cylinder 30.

[0027] Furthermore, referring to Figure 3 A rolling element 50 is also provided between the bottom of the cylindrical base 10 and the bottom of the discharge cylinder 30 to reduce friction. The rolling element 50 effectively reduces the cross-sectional contact area between the cylindrical base 10 and the bottom of the discharge cylinder 30, thereby reducing rotational friction.

[0028] Specifically, the rolling element 50 consists of multiple rollers evenly arranged around the circumference of the cylindrical base 10, and the bottom of the discharge cylinder 30 is placed on the multiple rollers. The cylindrical base 10 includes a base plate 11 and a cylinder 12 disposed on the base plate 11. Multiple receiving grooves (not labeled in the figure) are evenly arranged on the base plate 11, and the multiple rollers are disposed in the receiving grooves.

[0029] Reference Figure 3 In this embodiment, a U-shaped bracket 13 is provided inside the base plate 11, and the drive motor 20 is fixed to the top plate of the U-shaped bracket 13. The bottom of the base plate 11 has a hollow hole, and the two side plates of the U-shaped bracket are respectively fixed to the two sides of the hollow hole, while the drive motor 20 is located inside the hollow hole and fixed to the top plate. This structure provides good fixed support for the drive motor 20.

[0030] In this embodiment, the spiral guide groove 40 is formed by extending outward from the side wall of the cylinder 12 and spirally arranged. An installation port is also provided at the bottom discharge end of the spiral guide groove 40, and a discharge hopper 60 is provided at the installation port. In this way, the seamless connection with downstream equipment is achieved by integrating the side spiral discharge with the final discharge from the discharge hopper 60.

[0031] In this embodiment, the working process of the discrete material discharge device is as follows: When the drive motor 20 is not started, the discharge ports 32 of the two discharge bins 31 are blocked by the discharge cylinder 30, and the material is placed in the two independent bins 31 of the discharge cylinder 30. When the drive motor 20 is working, it drives the discharge cylinder 30 to rotate. At this time, the first rectangular discharge port 32 first forms a V-shaped channel with the edge of the spiral guide groove 40, and the material in the corresponding first bin 31 begins to be discharged in an orderly manner. As the rotation angle of the discharge cylinder 30 increases, the second rectangular discharge port 32 then forms a V-shaped channel with the edge of the spiral guide groove 40, and the material in the second bin 31 begins to be discharged in an orderly manner. During the material discharge process, the ribs 36 on the inner wall of the discharge cylinder 30 respectively agitate the material in the two bins 31, improving the flowability. Finally, under the influence of gravity, the materials in the two hoppers 31 sequentially and orderly peel off from the top layer of their respective V-shaped openings, sliding along the side spiral guide grooves 40 towards the discharge hopper 60. This eliminates the mechanical conditions that would lead to the arch bridge and allows for direct connection with the downstream equipment's inlet, achieving continuous feeding. When the material reaches the bottom, the irregularly shaped ramp on the conical bottom surface of the discharge cylinder 30 guides the remaining tailings towards the discharge port 32 for complete discharge. After the material is emptied, the drive motor 20 reverses the discharge cylinder 30, returning it to the initial hopper 31 state.

[0032] The discrete material discharge device in this application simplifies the equipment structure through integrated design, and the optimized support system ensures operational stability. These design features enable the device to maintain high discharge accuracy while having good operating economy and ease of maintenance.

[0033] The embodiments described above are merely specific implementations of this application, but the scope of protection of this application is not limited thereto. Any changes or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in this application should be included within the scope of protection of this application.
